METHODS: Surveys of pediatricians and family medicine physicians were conducted in August to October 2007.

RESULTS: Response rates were 84% for pediatricians and 79% for family medicine physicians (N = 623). Proportions routinely offering the vaccine were 85% of pediatricians and 45% of family medicine physicians (P < .0001); 70% of pediatricians and 22% of family medicine strongly recommended the vaccine (P < .0001). Sixty-two percent of pediatricians and 32% of family medicine physicians (P < .0001) knew the age by which all 3 doses should be completed. Definite barriers to vaccine use included reported lack of coverage by insurance companies (family medicine physicians: 22%; pediatricians: 19%; not significant), costs of purchasing vaccine (family medicine physicians: 22%; pediatricians: 17%; not significant), lack of adequate reimbursement (family medicine physicians: 18%; pediatricians: 15%; not significant), concerns about safety (family medicine physicians: 25%; pediatricians: 9%; P < .0001), and concerns about adding another vaccine to the schedule (family medicine physicians: 22%; pediatricians: 5%; P < .0001).

CONCLUSIONS: Rates of offering the new rotavirus vaccine are high among pediatricians but <50% among family medicine physicians. Both specialties identified financial barriers to use of the vaccine, but family medicine physicians had significantly more concerns about safety and about adding another vaccine to the vaccination schedule.

METHODS: This Swedish, population-based, case-control study included 1216 case subjects with autistic disorders who were born between 1987 and 2002 and 6080 control subjects who were matched with respect to gender, birth year, and birth hospital. We assessed associations between gestational age and autistic disorders and adjusted for maternal, birth, and neonatal characteristics. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS: Compared with infants born at term, the unadjusted ORs for autistic disorders among very and moderately preterm infants were 2.05 [95% CI: 1.26–3.34] and 1.55 [95% CI: 1.22–1.96], respectively. When we controlled for maternal, pregnancy, and birth characteristics, ORs were reduced to 1.48 [95% CI: 0.77–2.84] and 1.33 [95% CI: 0.98–1.81], respectively. When we also controlled for neonatal complications, ORs were 0.98 [95% CI: 0.45–2.16] and 1.25 [95% CI: 0.90–1.75], respectively. Reductions in risks of autistic disorders related to preterm birth were primarily attributable to preeclampsia, small-for-gestational age birth, congenital malformations, low Apgar scores at 5 minutes, and intracranial bleeding, cerebral edema, or seizures in the neonatal period. Neonatal hypoglycemia, respiratory distress, and neonatal jaundice were associated with increased risk of autistic disorders for term but not preterm infants.

CONCLUSION: The increased risk of autistic disorders related to preterm birth is mediated primarily by prenatal and neonatal complications that occur more commonly among preterm infants.

METHODS: Neonates who were admitted to 7 NICUs and developed SNT were enrolled for daily data collection.

RESULTS: Among 3652 neonatal admissions, 194 neonates (5%) developed SNT. The median gestational age of 169 enrolled neonates was 27 weeks (interquartile range [IQR]: 24–32 weeks), and the median birth weight was 822 g (IQR: 670–1300 g). Platelet count nadirs were <20 x 10⁹, 20 to 39 x 10⁹, and 40 to 59 x 10⁹ platelets per L for 58 (34%), 64 (39%), and 47 (28%) of all enrolled infants, respectively. During the study, 31 infants (18%) had no recorded hemorrhage, 123 (73%) developed minor hemorrhage, and 15 (9%) developed major hemorrhage. Thirteen (87%) of 15 episodes of major hemorrhage occurred in neonates with gestational ages of <28 weeks. Platelet transfusions (n = 415) were administered to 116 infants (69%); for 338 (81%) transfusions, the main recorded reason was low platelet count. Transfusions increased the platelet count from a median of 27 x 10⁹ platelets per L (IQR: 19–36 x 10⁹ platelets per L) to 79 x 10⁹ platelets per L (IQR: 47.5–127 x 10⁹ platelets per L).

CONCLUSIONS: Although one third of neonates enrolled in this study developed thrombocytopenia of <20 x 10⁹ platelets per L, 91% did not develop major hemorrhage. Most platelet transfusions were given to neonates with thrombocytopenia with no bleeding or minor bleeding only.

METHODS: We used data on all live births in the United States (for the years 1989–1991, 1995–1997, and 2002–2004) and Nova Scotia, Canada (for the years 1988–2007). Gestational age-specific temporal trends in infant deaths resulting from respiratory distress syndrome were quantified in the United States, and gestational age-specific temporal trends in corticosteroid use and morbidity (respiratory distress syndrome and intraventricular hemorrhage) were quantified in Nova Scotia.

RESULTS: In the United States, infant deaths associated with respiratory distress syndrome decreased by 48% (95% confidence interval: 46%–50%) from 1989–1991 to 1995–1997 and then decreased by another 18% (95% confidence interval: 15%–22%) by 2002–2004. The latter mortality reduction was evident at 28 to 32 weeks but not 33 to 36 weeks of gestation. Corticosteroid use at 28 to 32 weeks was high in Nova Scotia and increased from 30.7% in 1988–1989 to 50.0% in 1996–1997 and to 52.9% in 2006–2007, whereas rates of use at 33 to 36 weeks were much lower (eg, 6.7%, 17.0%, and 15.7% at 34 weeks in the 3 periods). Increased corticosteroid use at 33 and 34 weeks was estimated to reduce respiratory distress syndrome substantially.

CONCLUSION: Addressing the knowledge-practice gap in corticosteroid use at 33 to 34 weeks should reduce infant morbidity and mortality rates.

METHODS: A prospective study of sending TM reminders to the primary medication administrator (patient or caregiver) for pediatric transplant recipients was performed. Patient records were reviewed, comparing the year before and the year of the study. The SD of serum tacrolimus levels was used as an indicator of adherence.

RESULTS: Forty-one patients provided consent. The median age was 15 years (range: 1–27 years), and the median age at the time of transplantation was 2 years (range: 4 months to 23 years). Fourteen patients (34%) were male. In 29 of 41 cases, the medications were self-administered by the patient. The mean duration of study was 13 ± 1.5 months. Twenty-two patients were receiving 1 immunosuppressant, 14 were receiving 2, and 5 were receiving 3. Thirteen patients (37%) stopped the study after 4 months. The mean tacrolimus level SD decreased from 3.46 µg/L before the study to 1.37 µg/L (P < .005). The number of immunosuppressants taken and patient self/caregiver medication administration did not significantly affect the results. The number of acute cellular rejection episodes decreased from 12 to 2 during the study. Risk factors for rejection were older age (17.67 vs 13.28 years) and administration of >1 immunosuppressant.

CONCLUSION: We observed significant improvement in medication adherence and a reduction in rejection episodes with TM reminders for pediatric recipients of liver transplants.

METHODS: Neonates at 35 weeks of gestation were enrolled in a prospective study. Two TcB determinations were performed for all enrolled neonates (N = 358). The first assessment (TcB₁) was performed at 24 ± 6 hours of age, followed by a second (TcB₂) ≥12 hours later. Changes in TcB levels were calculated. TcB values were plotted on an hour-specific serum bilirubin nomogram, and risk zones were recorded. Of the 358 neonates enrolled, 325 neonates (91%) were monitored for hyperbilirubinemia until 5 days of age.

RESULTS: The mean ages of TcB₁ and TcB₂ estimations were 23 ± 4 hours and 42 ± 4 hours, respectively. A total of 14.9% of neonates (48 of 325 neonates) developed hyperbilirubinemia by 5 days of age. The sensitivity, specificity, and positive and negative likelihood ratios for prediction of subsequent hyperbilirubinemia for TcB₁ (zone >2, >75th percentile) were 80.4%, 58.0%, 1.9, and 0.34; those for TcB₂ (zone >2, >75th percentile) were 82.6%, 79.0%, 4.0, and 0.22; and those for the change in TcB levels (>0.18 mg/dL per hour, >75th percentile) were 82.5%, 82.9%, 4.8, and 0.21, respectively. Gestational age, TcB risk zone, and change in TcB levels were found to be independent predictors of subsequent hyperbilirubinemia.

CONCLUSIONS: Single TcB measurements at 30 to 48 hours predict hyperbilirubinemia with a reasonably high degree of accuracy. Changes in TcB levels do not offer any added clinical benefit.

METHODS: Patients with mild/moderate dehydration requiring parenteral treatment in US emergency departments were eligible for this phase IV, multicenter, single-arm study. They received subcutaneous injection of 1 mL rHuPH20 (150 U), followed by subcutaneous infusion of 20 mL/kg isotonic fluid over the first hour. Subcutaneous rehydration was continued as needed for up to 72 hours. Rehydration was deemed successful if it was attributed by the investigator primarily to subcutaneous fluid infusion and the child was discharged without requiring an alternative method of rehydration.

RESULTS: Efficacy was evaluated in 51 patients (mean age: 1.9 years; mean weight: 11.2 kg). Initial subcutaneous catheter placement was achieved with 1 attempt for 46/51 (90.2%) of patients. Rehydration was successful for 43/51 (84.3%) of patients. Five patients (9.8%) were hospitalized but deemed to be rehydrated primarily through subcutaneous therapy, for a total of 48/51 (94.1%) of patients. No treatment-related systemic adverse events were reported, but 1 serious adverse event occurred (cellulitis at infusion site). Investigators found the procedure easy to perform for 96% of patients (49/51 patients), and 90% of parents (43/48 parents) were satisfied or very satisfied.

CONCLUSIONS: rHuPH20-facilitated subcutaneous hydration seems to be safe and effective for young children with mild/moderate dehydration. Subcutaneous access is achieved easily, and the procedure is well accepted by clinicians and parents.

METHODS: Infants with gestational ages of ≥37 weeks and ages of <7 days were studied. Case subjects had ≥1 bilirubin level above the 95th percentile (high-risk zone), whereas control subjects had bilirubin levels of <40th percentile (low-risk zone) at study entry.

RESULTS: A total of 153 case subjects (median bilirubin level: 15.7 mg/dL) and 299 control subjects (median bilirubin level: 4.6 mg/dL) were evaluated. There were no statistical differences in the frequencies of G6PD, UGT1A1, and SCLO1B1 gene variants between case and control subjects (G6PD: 5.2% vs 3.3%; UGT1A1: 14.4% vs 9.4%; SLCO1B1: 73.2% vs 73.6%). However, coexpression of the G6PD African A– mutation with UGT1A1 and/or SLCO1B1 variants was seen more frequently for case subjects. Case subjects more often demonstrated ≥2 factors contributing to hyperbilirubinemia, including ABO blood group heterospecificity in which the mother had blood group O (47.7% vs 11.4%), positive direct Coombs test results (33.3% vs 4%), sibling treated with phototherapy (16.3% vs 5.4%), maternal circulating blood group antibodies (10.5 vs 0.7%), maternal diabetes mellitus (13.1% vs 6.4%), and maternal East Asian ethnicity (6.5% vs 1.3%).

CONCLUSIONS: Clinical contributors to hyperbilirubinemia were identified more frequently for case subjects but individually G6PD, UGT1A1, and SLCO1B1 variants were not. Coexpression of the G6PD African A– mutation with UGT1A1 and SLCO1B1 variants was seen more often for case subjects.

METHODS: Information was collected regarding 39096 children <60 months of age in the nationally representative 2005–2006 National Family Health Survey of India. The exposures were maternal reports of physical, sexual, psychological, and any IPV. Outcomes included infant (0 to <12 months), older child (12 to <60 months), and any child (0 to <60 months) deaths.

RESULTS: Maternal experience of physical IPV was associated with increased mortality rates among all children (risk ratio [RR]: 1.21 [95% confidence interval [CI]: 1.13–1.30]), infants (RR: 1.24 [95% CI: 1.01–1.53]), and older children (RR: 1.25 [95% CI: 1.00–1.56]). Sexual and psychological IPV were less strongly associated with child death. The associations between maternal IPV and death did not differ according to the child's gender.

CONCLUSION: The robust association between exposure to household IPV and infant and child death could be attributable to the mother's inability to care for her child, psychological stress associated with witnessing violence, and the use of maternal violence victimization as a proxy for child violence victimization.

METHODS: Thirty-four children, 6 to 15 years of age, with a physician diagnosis of functional abdominal pain were assigned randomly to receive 2 months of standard medical care with or without home-based, guided imagery treatment. Children who received only standard medical care initially received guided imagery treatment after 2 months. Children were monitored for 6 months after completion of guided imagery treatment.

RESULTS: All treatment materials were reported to be self-explanatory, enjoyable, and easy to understand and to use. The compliance rate was 98.5%. In an intention-to-treat analysis, 63.1% of children in the guided imagery treatment group were treatment responders, compared with 26.7% in the standard medical care–only group (P = .03; number needed to treat: 3). Per-protocol analysis showed similar results (73.3% vs 28.6% responders). When the children in the standard medical care group also received guided imagery treatment, 61.5% became treatment responders. Treatment effects were maintained for 6 months (62.5% responders).

CONCLUSION: Guided imagery treatment plus medical care was superior to standard medical care only for the treatment of abdominal pain, and treatment effects were sustained over a long period.

METHODS: This was a cross-sectional study of patients who presented with AHFS to the ED at our institution from January 2003 to October 2006. We defined AHFS as "the gradual or rapid deterioration in heart failure signs and symptoms resulting in a need for urgent therapy." Patients were included when they had documented signs or symptoms of HF attributable to ventricular dysfunction. Patients were excluded when they were older than 21 years or had HF symptoms that were attributable to left-to-right intracardiac shunting or left-sided obstructive lesions. All eligible ED patient visits were adjudicated by a pediatric HF specialist.

RESULTS: Fifty-seven patient visits to the ED met inclusion criteria. There was a significant difference in time from arrival to treatment with a diuretic when the therapy was started in the ED rather than in the inpatient units. Median time to initiation of a vasoactive agent was significantly less for patients whose infusions were started in the ED compared with the ICU. Two patients died in the ED, and overall mortality or need for mechanical circulatory support for hospitalized patients was 18% (n = 10).

CONCLUSIONS: These data yield important insight into the clinical features and initial treatment of children who present with AHFS in the ED and may allow for improved recognition and treatment of this clinical syndrome.

METHODS: This was a cross-sectional analysis of the National Health and Nutrition Examination Survey from 2001 to 2006. Studied were 8216 children aged 6 to 17 years, representative of the US population. BMI was calculated by using measured height and weight and converted to percentiles for age in months and gender. Outcome measures (dyslipidemia, dysglycemia, and hypertension) were based on laboratory and physical examination results; these were analyzed as both continuous and categorical outcomes.

RESULTS: Significant increases for total cholesterol values and prevalence of abnormal cholesterol begin at the 80th percentile. Significant increases in glycohemoglobin values and prevalence of abnormal values begin at the 99th percentile. Consistent significant increases in the prevalence of high or borderline systolic blood pressure begin at the 90th percentile.

CONCLUSIONS: Intervening for overweight children and their health requires clinical interventions that target the right children. On the basis of our data, a judicious approach to screening could include consideration of lipid screening for children beginning at the 80th percentile but for dysglycemia at the 99th percentile. Current definitions of overweight and obese may be more useful for general recognition of potential health problems and discussions with parents and children about the need to address childhood obesity.

METHODS: We performed a cross-sectional analysis of self-reported data from 7193 high school girls who completed the 2005 Youth Risk Behavior Surveillance survey. We used multivariate logistic regression to examine associations among 3 weight indices (BMI calculated from self-reported weight and height, perceived weight, and weight misperception) and 6 sexual behaviors (ever had vaginal sex; sex before age 13; ≥4 sexual partners; and alcohol, condom, and oral contraceptive use at last sex) adjusting for age, race/ethnicity, and a history of intimate partner violence.

RESULTS: There were no differences in the likelihood of ever having sex on the basis of BMI or weight perception accuracy; however, girls who perceived themselves as overweight were less likely to have ever had sex. Among sexually active girls, those who had low BMI and perceived themselves as overweight or had overweight misperceptions were less likely to report condom use at last sex. Sexually active girls who perceived themselves as overweight were also more likely to have had sex before age 13. Associations between the 3 weight indices and sexual risk behaviors varied across racial/ethnic groups.

CONCLUSIONS: Sexual risk behaviors may be more common among girls who are underweight or perceive themselves (accurately or not) to be overweight and vary by racial/ethnic group. This suggests that girls at weight extremes and those from different racial backgrounds may have unique sexual health education and prevention needs.

METHODS: A prospective study was conducted of 180 term newborn infants who were undergoing heel-lancing for routine neonatal screening of phenylketonuria and hypothyroidism. Newborns were assigned to 6 groups: (1) control (no pain relief intervention); (2) nonnutritive sucking; (3) holding by mother; (4) oral glucose solution; (5) oral formula feeding; or (6) breastfeeding. Outcome measures included the Neonatal Facial Coding System score; cry duration; and autonomic variables obtained from spectral analysis of heart rate variability before, during, and after heel-lancing.

RESULTS: Infants with no pain control showed the highest pain manifestation compared with newborns to whom pain control was provided. Infants who breastfed or received an oral formula showed the lowest increase in heart rate (21 and 23 beats per minute, respectively, vs 36; P < .01), lowest neonatal facial score (2.3 and 2.9, respectively, vs 7.1; P < .001), lowest cry duration (5 and 13 seconds, respectively, vs 49; P < .001), and lowest decrease in parasympathetic tone (–2 and –2.4, respectively, vs 1.2; P < .02) compared with the other groups.

CONCLUSIONS: Any method of pain control is better than none. Feeding and breastfeeding during heel-lancing were found to be the most effective methods of pain relief.

METHODS: Data come from a school-based asthma case detection validation study of 3539 children. Respiratory symptoms, emergency department (ED) visits, and hospitalizations were assessed by questionnaire for children whose case detection result and physician study diagnosis agreed.

RESULTS: Physician evaluation of 530 case detection results yielded 420 cases of agreement (168 children with previously diagnosed asthma, 39 with undiagnosed asthma, and 213 without asthma). Children with previously diagnosed asthma were more likely to be male (P < .0001). No differences in severity were observed in children with previously and undiagnosed asthma (P = .31). Children with undiagnosed asthma reported less frequent daytime and nighttime symptoms than children with previously diagnosed asthma but more than those without asthma (P < .0001). The proportion of children with at least 1 respiratory-related ED visit in the past year was 32%, 3%, and 3% for those with previously diagnosed, undiagnosed, and no asthma, respectively (P < .0001). The proportion with at least 1 respiratory-related hospitalization was 8%, 0%, and 0%, respectively (P < .0001). There were no differences in nonrespiratory ED visits (P = .93).

CONCLUSIONS: Despite similar physician-rated severity, children with undiagnosed asthma reported significantly less frequent respiratory symptoms and health care use than children with previously diagnosed asthma. These findings suggest that the potential health gains from case detection may be smaller than expected.

METHODS: A cohort of consecutive term SGA newborns with normal prenatal umbilical artery Doppler ultrasound findings was created and compared with a group of term infants with size appropriate for gestational age, who were sampled from our general neonatal population. Neonatal behavior was evaluated at corrected age of 40 ± 1 weeks with the Neonatal Behavioral Assessment Scale. The effect of the study group on each Neonatal Behavioral Assessment Scale area was adjusted, through multivariate analysis of covariance, for smoking during pregnancy, maternal BMI, socioeconomic level, onset of labor, mode of delivery, use of epidural anesthetic medication, gestational age at delivery, postnatal age (in days) at evaluation, and gender.

RESULTS: A total of 202 newborns (102 SGA and 100 appropriate for gestational age) were included. All of the neurobehavioral areas studied were poorer in the SGA group, with significance for attention, habituation, motor, social-interactive, and regulation of state. The average mean differences in scores between the study groups were 0.77 (95% confidence interval: 0.38–1. 14) for attention, 0.64 (95% confidence interval: 0.13–1.14) for habituation, 0.52 (95% confidence interval: 0.31–0.74) for motor, 0.95 (95% confidence interval: 0.54–1.37) for social-interactive, and 0.68 (95% confidence interval: 0.23–1.13) for regulation of state. These differences remained significant after adjustment for potential confounders.

CONCLUSION: Term SGA newborns with no signs of placental insufficiency had poorer neurobehavioral competencies, which suggests delayed neurologic maturation.

METHODS: Fontan procedure survivors 10 to 18 years of age were included in the study if the child completed the Child Health Questionnaire (CHQ) and the parent completed the parent form to assess the child's functional health status. Comparisons were made between raw domain scores for the parent- and child-completed CHQs.

RESULTS: Between March 2003 and April 2004, 1078 Fontan survivors were screened. Of the 546 eligible and consented patients, 354 were 10–18 years of age and 328 parent/child pairs completed the CHQs. Parents reported significantly lower scores (worse functioning) for their children than the children reported for themselves in the domains of physical functioning (P < .01), impact on school or activities from emotional and behavioral problems (P < .01), impact on school or activities from physical health issues (P < .01), general behavior (P < .01), mental health (P < .01), self-esteem (P < .01), and general health perceptions (P < .01). No significant differences were noted for the domains of bodily pain, family cohesiveness, or family activities. For the physical functioning domain, factors contributing to lower scores for parent versus child reports included pulmonary artery anomalies and fenestration at the time of the Fontan operation. Lower parent-reported scores also were associated with more noncardiac health problems in the child.

CONCLUSIONS: Parents' perceptions of the functional health status of their children after the Fontan procedure were worse than the children's perceptions.

METHODS: Sixty-one preterm infants with RDS undergoing mechanical ventilation received, within 24 hours after birth, 100 mg/kg (N = 40) or 200 mg/kg (N = 21) porcine surfactant mixed with [U-¹³C]dipalmitoylphosphatidylcholine. Clinical and respiratory parameters were recorded, and DSPC half-life and pool size and endogenous DSPC synthesis rate were calculated.

RESULTS: Clinical characteristics and short-term outcomes did not differ between groups. In the 100 mg/kg group, 28 infants (70%) received a second dose after 25 ± 11 hours and 9 (22.5%) a third dose after 41 ± 11 hours; in the 200 mg/kg group, 6 infants (28.6%) received a second dose after 33 ± 8 hours and 1 a third dose. The DSPC half-life was longer in the 200 mg/kg group (first dose: 32 ± 19 vs 15 ± 15 hours [P = .002]; second dose: 43 ± 32 vs 21 ± 13 hours [P = .025]). DSPC synthesis rates and pool sizes before the first and second doses did not differ between the groups. The 200 mg/kg group exhibited a greater reduction in the oxygenation index than did the 100 mg/kg group after the first (P = .009) and second (P = .018) doses.

CONCLUSIONS: Porcine surfactant given to preterm infants with RDS at a dose of 200 mg/kg resulted in a longer DSPC half-life, fewer retreatments, and better oxygenation index values.

METHODS: Forty-six preterm newborns with gestational ages of <33 weeks and 25 healthy term newborns were included. The cerebral tissue oxygenation index (c-TOI) was measured by using near-infrared spectroscopy in clinical steady state on the first day of life (median age: 19.2 hours). The mean gestational ages and birth weights in the 2 groups were 29.1 ± 2.6 weeks versus 39.7 ± 1.3 weeks and 1307 ± 437 g versus 3484 ± 346 g, respectively. Three preterm infants needed mechanical ventilation and 11 received inotropic drugs. Later, 3 preterm infants developed intraventricular hemorrhage and 2 infants died. All term infants were healthy newborns recruited in the maternity ward.

RESULTS: There was a significant difference in c-TOI (preterm: 78.6% [95% confidence interval: 76.9%–80.3%]; term: 74.7% [95% confidence interval: 72.3%–77.1%]). Preterm newborns had significantly lower fractional tissue oxygen extraction, which suggests lower oxygen extraction in this group. There was no significant correlation between head size and c-TOI. The mean peripheral oxygen saturation was 95% in both groups. The median blood Pco₂ for the preterm infants was 6.1 kPa (range: 3.4–7.3 kPa).

CONCLUSIONS: Cerebral oxygenation on the first day of life was higher in a group of relatively healthy, very preterm infants in stable condition, compared with healthy term newborns. Slightly elevated blood Pco₂ could be the explanation. Prematurity itself does not seem to dispose preterm infants to global cerebral hypoxia.

METHODS: High-resolution anatomic and diffusion tensor imaging data measuring diffusion in 30 directions were collected by using a 1.5-T MRI scanner. A total of 143 adolescents (12.18–17.7 years of age) participated in the study, including 74 formerly preterm infants with birth weights of ≤1500 g (range: 645–1486 g) and 69 term control subjects. The 2 groups were well matched with respect to demographic and socioeconomic data. The anatomic MRI data were used for calculation of total brain volumes and voxelwise comparison of gray matter (GM) volumes. The diffusion tensor imaging data were used for voxelwise comparison of white matter (WM) microstructural integrity.

RESULTS: The formerly preterm individuals possessed 8.8% smaller GM volume and 9.4% smaller WM volume. The GM and WM volumes of individuals depended on gestational age and birth weight. The reduction in GM could be attributed bilaterally to the temporal lobes, central, prefrontal, orbitofrontal, and parietal cortices, caudate nuclei, hippocampi, and thalami. Lower fractional anisotropy was observed in the posterior corpus callosum, fornix, and external capsules.

CONCLUSIONS: Although preterm birth was found to be a risk factor regarding long-term structural brain development, the outcome was milder than in previous reports. This may be attributable to differences in social structure and neonatal care practices.

METHODS: A total of 115 English-speaking families caring for children with type 1 diabetes mellitus who were attending the diabetes clinic at Texas Children's Hospital agreed to a questionnaire study designed to ascertain their level of preparedness for a disaster or emergency. The study was conducted from June through September 2008 and ended just before Hurricane Ike made landfall.

RESULTS: Families were better prepared for self-management of diabetes, compared with general disaster preparedness. Sixty-two percent of the families were generally unprepared for a major disaster. For self-management of diabetes specifically, however, 75% of families had adequate supplies to maintain care for 3 days. Families in higher and moderate socioeconomic status strata were better equipped for an emergency (P < .002). Preparedness was found to be independent of age, gender, ethnicity, and previous experience of a disaster.

CONCLUSION: Disaster preparedness still lags in families of lower socioeconomic status.

METHODS: We conducted a prospective, randomized, clinical trial with infants with birth weights of <1500 g (N = 20). The infants were assigned randomly to receive either a standard dose (45 mg/kg per day) or a high dose (81 mg/kg per day) of cysteine. Intakes of other amino acids were similar, providing a total protein intake of 2.4 g/kg per day in both groups. We recorded base requirements in the first 6 days of life. On postnatal day 2, we conducted a stable isotope study to determine glutathione concentrations and synthesis rates in erythrocytes.

RESULTS: Base requirements were higher in the high-dose cysteine group on days 3, 4, and 5. Despite an 80% increase in cysteine intake, plasma cystine concentrations did not increase. Glutathione concentrations and synthesis rates did not increase with additional cysteine administration.

CONCLUSIONS: Administration of a high dose of cysteine (81 mg/kg per day) to preterm infants seems clinically safe but does not stimulate glutathione synthesis, compared with a lower dose (45 mg/kg per day). Further research is required to determine whether there is significant benefit associated with cysteine supplementation.

DESIGN, SETTING, AND PARTICIPANTS: Nighttime sleep duration and hyperactivity were measured yearly by questionnaires administered to mothers of 2057 children from age 1.5 to 5 years. Developmental trajectories of nighttime sleep duration and hyperactivity throughout early childhood were analyzed to determine interassociations. A multinomial logistic regression was performed to determine which factors among selected child, maternal, and family characteristics and parental practices surrounding sleep periods in early childhood were associated with short nighttime sleep duration and high hyperactivity scores.

RESULTS: The trajectories of nighttime sleep duration and hyperactivity were significantly associated. The odds ratio (OR) of reporting short nighttime sleep duration was 5.1 for highly hyperactive children (confidence interval [CI]: 3.2–7.9), whereas the OR of reporting high hyperactivity scores was 4.2 for persistently short sleepers (CI: 2.7–6.6). The risk factors for reporting short nighttime sleep duration and high hyperactivity scores were (1) being a boy, (2) having insufficient household income, (3) having a mother with a low education, and (4) being comforted outside the bed after a nocturnal awakening at 1.5 years of age.

CONCLUSIONS: The risk of short nighttime sleep duration in highly hyperactive children is greater than the risk of high hyperactivity scores in short sleepers. Preventive interventions that target boys living in adverse familial conditions could be used to address these concomitant behavioral problems.

METHODS: This is a community-based cross-sectional study with 5159 children (49.6% boys), mean age of 9.25 years (SD: 1.78), from 13 primary schools in Hong Kong. Data on sleep patterns, lifestyle, body weight, and height of children were obtained from questionnaires. Sleep durations during weekdays, weekends, and holidays were predictor variables. BMI z scores and obesity/overweight status were the outcome measures.

RESULTS: Children slept significantly longer during holidays (mean [SD]: 10.20 (0.92) hours) and weekends (school terms) (10.07 [0.93] hours) than during school weekdays (9.18 [0.95] hours). Children with shorter sleep duration had higher BMI z scores regardless of the sleep parameters used in the analysis. Among children who slept <8 hours during weekdays, those children who did not compensate for their sleep deficit during weekends or holidays had significantly increased risk of overweight/obesity compared with those children with sleep compensation (odds ratios: 2.59 [95% confidence interval: 1.22–5.48] and 2.32 [95% confidence interval: 1.00–5.53], respectively).

CONCLUSIONS: There was a prominent difference in sleep duration between weekdays and weekends/holidays among school children. Short sleep duration was associated with higher BMI, but compensation of sleep during weekends/holidays may partly ameliorate the risk of childhood overweight/obesity. Further prospective and interventional study is needed to delineate the risk-benefit effect of these increasingly common sleep habits among children and adolescents.

METHODS: A total of 1467 infants born before the 28th postmenstrual week at 14 institutions were given Score for Neonatal Acute Physiology II (SNAP-II) and Score for Neonatal Acute Physiology Perinatal Extension II (SNAPPE-II) values based on data collected within the first 12 postnatal hours. All deaths in the intensive care nursery were identified.

RESULTS: The rate of death before postnatal day 28 was 13% (interinstitutional range: 7%–20%), whereas the overall mortality rate was 18% (8%–31%). SNAP-II values, SNAPPE-II values, and mortality rates tended to decrease with increasing gestational age. Even within gestational age strata, however, the risk of death decreased with decreasing SNAP-II and SNAPPE-II values. The positive predictive values of most SNAP-II and SNAPPE-II cutoff levels were close to 30%. In general, institutions' mortality rates increased with the proportions of infants whose SNAP-II values were ≥30.

CONCLUSION: The physiologic instability in the first 12 postnatal hours that is identified by illness severity scores conveys information about the risk of death among infants at the lowest gestational ages.

METHODS: School-aged boys with severe hemophilia A or B at a single center were included in the study. Clinical data on baseline joint status, BMI, hemophilia treatment, bleeding episodes, joint assessments, athletic participation, and injuries were retrospectively reviewed. Data on athletic participation were supplemented, when incomplete in the medical record, via structured telephone interview.

RESULTS: Among 37 children with severe hemophilia A or B receiving factor prophylaxis, 73% participated in high-impact activities, whereas 27% participated in exclusively low-impact activities. The frequency of joint hemorrhages and new injuries did not appreciably differ between high- and low-impact athletics. In most instances, children developed <1 bleed or injury per season. A new target joint developed in 1 (3%) child. Sixteen percent of children met established BMI criteria for overweight, and 3% were obese. In logistic regression analyses with adjustment for prophylaxis frequency, level of athletic participation was not a significant prognostic factor for joint hemorrhage.

CONCLUSIONS: In the setting of regular prophylaxis and adult coaching and supervision, significant bleeding complications were uncommon and level of impact of athletic participation was not a prognostic factor for joint outcomes. Athletic participation with appropriate supervision and precautions should be encouraged in children with hemophilia receiving prophylaxis, given potential health benefits in an increasingly overweight pediatric population.

METHODS: The HRSA Maternal and Child Health Bureau's health insurance core outcome was measured on the basis of whether a child had public or private coverage at the time of survey; continuity of coverage during the previous 12 months; and adequacy of coverage. Bivariate and multivariate statistical methods were used to assess independent predictors of respondents who met the health insurance core outcome and the impact of meeting the core outcome on measures of access and financial burden. Comparisons with a referent sample of children who did and did not have special needs and were included in the 2001 NS-CSHCN are also presented.

RESULTS: A total of 62.0% of CSHCN nationally met the health insurance core outcome in 2005–2006, up from 59.6% in 2001. Disparities by ethnicity and income remain, but some have narrowed, especially for Hispanic CSHCN. Children who did not meet the health insurance core outcome were more likely to have unmet needs and their families to experience financial problems. CSHCN were more likely to be insured than children without special needs but less likely to be adequately insured.

CONCLUSIONS: Results of the survey demonstrate that although a growing number of CSHCN have continuous and adequate health insurance, additional effort is needed to improve the adequacy of that insurance, particularly for children in vulnerable subpopulations.

METHODS: Data were collected from a longitudinal study of children who were involved in crashes in 16 states and the District of Columbia from December 1, 1998, to November 30, 2007, with data collected via insurance claims records and a validated telephone survey. The study sample included children who were aged 4 to 8 years, seated in the rear rows of the vehicle, and restrained by either a seat belt or a BPB seat. Multivariable logistic regression was used to determine the odds of injury for those in BPB seats versus those in seat belts. Effects of crash direction and booster seat type were also explored.

RESULTS: Complete interview data were obtained on 7151 children in 6591 crashes representing an estimated 120646 children in 116503 crashes in the study population. The adjusted relative risk for injury to children in BPB seats compared with those in seat belts was 0.55.

CONCLUSIONS: This study reconfirms previous reports that BPB seats reduce the risk for injury in children aged 4 through 8 years. On the basis of these analyses, parents, pediatricians, and health educators should continue to recommend as best practice the use of BPB seats once a child outgrows a harness-based child restraint until he or she is at least 8 years of age.

METHODS: DRIVE is a prospective cohort study of 20822 first-year drivers aged 17 to 24 in New South Wales (NSW), Australia. Participants completed a detailed questionnaire and consented to data linkage in 2003–2004. Questionnaire items included year of participation in 2 specific education programs: a 1-day workshop-only program focusing on driving risks ("driver-focused") and a whole-of-community program also including a 1-day workshop but also longer term follow-up activities and a broader focus on reducing risk-taking and building resilience ("resilience-focused"). Survey data were subsequently linked to police-reported crash and offense data for 1996–2005. Poisson regression models that adjusted for multiple confounders were created to explore offenses and crashes as a driver (dichotomized as 0 vs ≥1) after program participation.

RESULTS: Offenses did not differ between groups; however, whereas the driver-focused program was not associated with reduced crash risk, the resilience-focused program was associated with a 44% reduced relative risk for crash (0.56 [95% confidence interval: 0.34–0.93]).

CONCLUSIONS: The large effect size observed and complementary findings from a comparable randomized, controlled trial in the United States suggest programs that focus more generally on reducing risks and building resilience have the potential to reduce crashes. A large, representative, randomized, controlled trial is urgently needed to confirm road safety benefits and ensure evidence-based spending and practitioner recommendations in this field.

METHODS: This was an observational study from January to June 2008. Participants were children in grades 4 through 6 from 10 urban K-8 schools with ≥50% of students eligible for free or reduced-price meals. A total of 833 intercept surveys of children's purchases were conducted outside 24 corner stores before and after school. The main outcomes were type and energy content of items purchased.

RESULTS: The most frequently purchased items were energy-dense, low-nutritive foods and beverages, such as chips, candy, and sugar-sweetened beverages. Students spent $1.07 ± 0.93 on 2.1 ± 1.3 items (1.6 ± 1.1 food items and 0.5 ± 0.6 beverage items) per purchase. The total number of calories purchased per trip was 1497.7 ± 1219.3 kJ (356.6 ± 290.3 kcal). More calories came from foods than from beverages.

CONCLUSIONS: Purchases made in corner stores contribute significantly to energy intake among urban school children. Obesity prevention efforts, as well as broader efforts to enhance dietary quality among children in urban settings, should include corner store environments proximal to schools.

METHODS: We analyzed serum cotinine data from the 2003–2006 National Health and Nutrition Examination Survey for 5518 children (3–11 years) and nonsmoking adolescents (12–19 years). We calculated geometric mean serum cotinine levels by sociodemographic and household characteristics according to self-reported home SHS exposure. Multiple regression analysis was conducted to evaluate independent predictors of serum cotinine levels.

RESULTS: Geometric mean serum cotinine levels were 1.05 ng/mL among those with home SHS exposure and 0.05 ng/mL among those without home exposure. Among children who were exposed to SHS at home, serum cotinine levels were inversely associated with age and were similar for non-Hispanic black and non-Hispanic white children. Conversely, among children without SHS exposure at home, serum cotinine levels were higher among non-Hispanic black compared with non-Hispanic white children, and there was no relationship with age. Mexican American children had the lowest level of SHS exposure.

CONCLUSIONS: Serum cotinine levels were an order of magnitude higher among children with reported SHS exposure at home compared with those with no exposure in the home.

METHODS: A total of 32506 students aged 11 to 20 years from 85 randomly selected secondary schools in Hong Kong completed a self-administered questionnaire that included persistent respiratory symptoms (for 3 consecutive months in the past 12 months), number of days of SHS exposure per week at home and outside home, smoking status, amount of active smoking, and other basic demographic characteristics and socioeconomic status.

RESULTS: Adolescent current smokers who were exposed to SHS at home 1 to 4 and 5 to 7 days/wk were 50% (95% confidence interval [CI]: 3%–121%) and 77% (95% CI: 5%–199%) more likely, respectively, to report respiratory symptoms compared with those who were unexposed (P = .01 for trend). The corresponding figures for exposure outside home were 41% (95% CI: 3%–94%) and 85% (95% CI: 31%–161%; P = .004 for trend). Such associations were also observed among never-smokers, but they were weaker than those among current smokers (P < .01 for interaction).

CONCLUSIONS: This is the first evidence that SHS exposure is associated with increased risks for persistent respiratory symptoms among adolescent current smokers. Health promotion programs should aim at SHS reduction as well as smoking cessation among adolescent smokers.

METHODS: We conducted an analysis of restricted-access data from the complete long form of Census 2000 for internationally adopted children aged 5 to 15 in 2000, estimating disability rates by country of origin, controlling for gender, age at adoption, current age, and parental characteristics.

RESULTS: Internationally adopted children have disability rates similar to those adopted domestically (11.7% vs 12.2%, respectively) and more than twice the rate for all children in that age range (5.8%). The adjusted odds of disability relative to domestic adoptees range from one half or less (China and Korea) to twice as large or more (Romania, Bulgaria, other Eastern Europe, and other Western Europe).

CONCLUSIONS: The population of internationally adopted children is relatively small and diverse, posing challenges for researchers who hope to reach generalizable conclusions. Nevertheless, health, education, and social service professionals, as well as adoptive and prospective adoptive parents, should be aware of the risk for disabilities among internationally adopted children to devote the resources necessary to addressing them.

METHODS: A retrospective study was undertaken of published cases both fatal and nonfatal and included personal communications, referenced citations, clinical experience, and theoretical formulations as to causation. Characteristic AEA manifestations, prevalence, age range, methods of inducing hypoxia/anoxia, and gender weighting are presented. All sources were used as a basis for additional considerations of etiology and possibilities for intervention.

RESULTS: AEA can be conceptualized as a personalized, ritualized, and symbolic biopsychosocial drama. It seems to be a reenactment of intense emotional feeling-states involving an identification and sadomasochistic relationship with a female figure. Inept AEA practitioners can miscalculate the peril of the situation that they have contrived and for numerous reasons lose their gamble with death.

CONCLUSIONS: Pediatricians should be alert to the earliest manifestations of AEA. Awareness of choking games among the young and, of those, a subset who eventually progress to potentially fatal AEA is strongly encouraged among all primary care professionals who may be able to interrupt the behavior.

METHODS: We used patient-level data from the NO CLD randomized trial. The study took a third-party payer perspective and measured costs and effects through hospital discharge. We applied previously reported hospital per-diem costs stratified according to intensity of ventilatory support, nitric oxide costs from standard market prices, and professional (physician) fees from the Medicare fee schedule. We compared log transformed costs by using multivariable modeling and performed incremental cost-effectiveness analysis with estimation of uncertainty through nonparametric bootstrapping.

RESULTS: The mean cost per infant was $193125 in the placebo group and $194702 in the iNO group (adjusted P = .17). The point estimate for the incremental cost per additional survivor without BPD was $21297. For infants in whom iNO was initiated between 7 and 14 days of life, the mean cost per infant was $187407 in the placebo group and $181525 in the iNO group (adjusted P = .46). In this group of early treated infants, there was a 71% probability that iNO actually decreased costs while improving outcomes.

CONCLUSIONS: Despite its higher price relative to many other neonatal therapies, iNO in this trial was not associated with higher costs of care, an effect that is likely due to its impact on length of stay and ventilation. Indeed, for infants who receive nitric oxide between 7 and 14 days of life, the therapy seemed to lower costs while improving outcomes.

METHODS: Premature newborns (gestational age ≤34 w, birth weight 500–1250 g) with respiratory failure randomly received 5 ppm iNO or placebo within 48 h of birth until 21 d or extubation. We assessed clinical outcomes via in-person neurodevelopmental evaluation at 1 y corrected age and telephone interviews every 3 m. We estimated costs from detailed hospital bills and interviews, converting all costs to 2008 US$. Of 793 trial subjects, 631 (79.6%) contributed economic data, and 455 (77.1% of survivors) underwent neurodevelopmental evaluation.

RESULTS: At 1 y corrected age, survival was not different by treatment arm (79.2% iNO vs. 74.5% placebo, P = .12), nor were other post-discharge outcomes. For subjects weighing 750–999 g, those receiving iNO had greater survival free from neurodevelopmental impairment (67.9% vs. 55.6%, P = .04). However, in subjects weighing 500–749 g, iNO led to greater oxygen dependency (11.7% vs. 4.0%, P = .04). Median total costs were similar ($235 800 iNO vs. $198 300 placebo, P = .19). Quality-adjusted survival was marginally better with iNO (by 0.011 quality-adjusted life-years/subject). The incremental cost-effectiveness ratio was $2.25 million/quality-adjusted life-year.

CONCLUSIONS: Subjects in both arms commonly experienced neurodevelopmental and pulmonary morbidity, consuming substantial health care resources. Prophylactic iNO beginning in the first days of life did not lower costs and had a poor cost-effectiveness profile.

PATIENTS AND METHODS: This was a randomized, 28-day pilot trial of pramlintide (maximum dose: 30 µg per meal) in 10 adolescents aged 13 to 17 years. End points included changes in hemoglobin A1c (HbA1c) values, body weight, and postprandial peak blood glucose levels and area under the curve on continuous glucose monitoring.

RESULTS: Changes in HbA1c values, body weight, and total insulin dose declined in the treatment group compared with the control group (bootstrapped, P ≤ .02 for each). The treatment group also demonstrated lower average dinner area under the curve (P = .02) and lower maximum breakfast (P = .03) and dinner (P = .02) postprandial blood glucose values.

CONCLUSIONS: Pramlintide can help some adolescents to decrease postprandial hyperglycemia, HbA1c values, body weight, and insulin dosages. Additional large-scale trials should now be considered.

METHODS: To develop the survey, we conducted 2 focus groups and conducted 9 cognitive interviews. We conducted a telephone pretest with 20 parents and coded potential problems with the interview (behavioral coding). We conducted a dual-language field test of the instrument with 670 parents who reported about their children's ambulatory care. We used data from that survey to assess the reliability and validity of the measures.

RESULTS: Questions about developmental monitoring and preventive care were developed and tested. Two scales that were based on those new questions had good internal consistency (coefficient ) and inter-physician reliability. A consortium of CAHPS investigators and federal sponsors have approved the resulting instrument as a national measure of pediatric care.

CONCLUSIONS: A new instrument for assessing ambulatory pediatric care by clinicians and groups that includes questions about developmental and preventive care is now available for use.

METHODS: The sample included 360 cocaine-exposed and 480 unexposed children from lower to lower middle class families of which 78% were black. Structural equation modeling was used to test models whereby prenatal exposure to cocaine and other substances would result in neurobehavioral dysregulation in infancy, which would predict externalizing and internalizing behavior problems in early childhood. Structural equation models were developed for individual and combined parent and teacher report for externalizing, internalizing, and total problem scores on the Child Behavior Checklist.

RESULTS: The goodness-of-fit statistics indicated that all of the models met criteria for adequate fit with 7 of the 9 models explaining 18% to 60% of the variance in behavior problems at age 7. The paths in the models indicate that there are direct effects of prenatal substance exposure on 7-year behavior problems as well as indirect effects, including neurobehavioral dysregulation.

CONCLUSIONS: Prenatal substance exposure affects behavior problems at age 7 through 2 mechanisms. The direct pathway is consistent with a teratogenic effect. Indirect pathways suggest cascading effects whereby prenatal substance exposure results in neurobehavioral dysregulation manifesting as deviations in later behavioral expression. Developmental models provide an understanding of pathways that describe how prenatal substance exposure affects child outcome and have significant implications for early identification and prevention.

METHODS: We conducted a cross-sectional survey of Oregon's food stamp program in 2005. We analyzed primary data from 2681 surveys and then weighted results to 84087 families, adjusting for oversampling and nonresponse. We then ascertained the percentage of children in the Oregon population who had ever changed a USC for insurance reasons, which characteristics were associated with USC change, and how USC change was associated with unmet need. We also conducted a posthoc analysis of data from the Medical Expenditure Panel Survey to confirm similarities between the Oregon sample and a comparable national sample.

RESULTS: Children without a USC in the Oregon population had greater odds of reporting an unmet health care need than those with a USC. This pattern was similar in national estimates. Among the Oregon sample, 23% had changed their USC because of insurance reasons, and 10% had no current USC. Compared with children with a stable USC, children who had changed their USC had greater odds of reporting unmet medical need, unmet prescription need, delayed care, unmet dental need, and unmet counseling need.

CONCLUSIONS: This study highlights the importance of ensuring stability with a USC. Moving low-income children into new medical homes could disturb existing USC relationships, thereby merely creating "temporary housing."

METHODS: Bone area (BA) and bone mineral content (BMC) of lumbar spine, hip, and whole body were measured with dual radiograph absorptiometry in 13- to 15-year-olds who were born preterm and randomly assigned standard or aluminum-depleted parenteral nutrition solutions during the neonatal period.

RESULTS: Fifty-nine children (32% of survivors) were followed. Those who were randomly assigned to standard parenteral nutrition solution had lower lumbar spine BMC, apparently explained by a concomitant decrease in bone size. In nonrandomized analyses, children who were exposed to neonatal aluminum intakes above the median (55 µg/kg) had lower hip BMC (by 7.6% [95% confidence interval 0.21–13.8]; P = 0.02), independent of bone (or body) size.

CONCLUSIONS: Neonates who are exposed to parenteral aluminum may have reduced lumbar spine and hip bone mass during adolescence, potential risk factors for later osteoporosis and hip fracture. These findings need confirmation in larger, more detailed studies. Nevertheless, given our previous finding of adverse developmental outcome in these individuals and the sizeable number of contemporary infants who undergo intensive neonatal care and are still exposed to aluminum via parenteral feeding solutions, the potential adverse long-term consequences of early aluminum exposure now deserve renewed attention.

METHODS: A cross-sectional study of 524 children in the second grade from 10 public schools was performed. A positive response rate was obtained for 416 (79.4%) children, and 411 (78.4%) children were clinically examined and tested for motor competence, whereas questionnaire response to items comprising musculoskeletal pain and injuries, in addition to daily level and duration of physical activity, corresponded to 377 (71.9%) children.

RESULTS: In total, 29% of the children had GJH4, 19% had GJH5, 10% had GJH6, and 9% had BJHS, with no gender difference. There was no difference in daily level and duration of physical activity and in frequency of musculoskeletal pain and injuries between those with and without GJH. Children with ≥GJH5 as well as with ≥GJH6 performed better in the motor competence tests.

CONCLUSION: Motor competence and physical activity are not reduced in primary school children at 8 years of age with GJH or BJHS. It is recommended that a potential negative influence on the musculoskeletal system over time, as a result of GJH, be investigated by longitudinal studies.

PATIENTS AND METHODS: Patients with Salmonella Paratyphi B var Java infections with a specific pulsed-field gel electrophoresis pattern (outbreak strain) and illness onset between May 2007 and January 2008, were compared with healthy controls. Reptile exposure and awareness of a Salmonella-reptile link were assessed. Turtle size and purchase information were collected.

RESULTS: We identified 107 patients with outbreak-strain infections. The median patient age was 7 years; 33% were hospitalized. Forty-seven (60%) of 78 patients interviewed reported exposure to turtles during the week before illness; 41 (87%) were small turtles, and 16 (34%) were purchased in a retail pet store. In the case-control study, 72% of 25 patients reported turtle exposure during the week before illness compared with 4% of 45 controls (matched odds ratio [mOR]: 40.9 [95% confidence interval (CI): 6.9–unbounded]). Seven (32%) of 22 patients versus 11 (28%) of 39 controls reported knowledge of a link between reptile exposure and Salmonella infection (mOR: 1.3 [95% CI: 0.4–4.6]).

CONCLUSIONS: We observed a strong association between turtle exposure and Salmonella infections in this outbreak. Small turtles continue to be sold and pose a health risk, especially to children; many people remain unaware of the link between Salmonella infection and reptile contact.

METHODS: The prevalence of parent-reported diagnosis of ASD among US children aged 3 to 17 years was estimated from the 2007 National Survey of Children's Health (sample size: 78037). A child was considered to have ASD if a parent/guardian reported that a doctor or other health care provider had ever said that the child had ASD and that the child currently had the condition. The point-prevalence for ASD was calculated for those children meeting both criteria. We examined sociodemographic factors associated with current ASD and with a past (but not current) ASD diagnosis. The health care experiences for children in both ASD groups were explored.

RESULTS: The weighted current ASD point-prevalence was 110 per 10,000. We estimate that 673,000 US children have ASD. Odds of having ASD were 4 times as large for boys than girls. Non-Hispanic (NH) black and multiracial children had lower odds of ASD than NH white children. Nearly 40% of those ever diagnosed with ASD did not currently have the condition; NH black children were more likely than NH white children to not have current ASD. Children in both ASD groups were less likely than children without ASD to receive care within a medical home.

CONCLUSIONS: The observed point-prevalence is higher than previous US estimates. More inclusive survey questions, increased population awareness, and improved screening and identification by providers may partly explain this finding.

METHODS: Data were obtained from the 2001–2006 National Health and Nutrition Examination Survey. Serum 25(OH)D levels were determined by radioimmunoassay and categorized as <25, <50, and <75 nmol/L. National estimates were obtained by using assigned patient visit weights and reported with 95% confidence intervals (CIs).

RESULTS: During the 2001–2006 time period, the mean serum 25(OH)D level for US children aged 1 to 11 years was 68 nmol/L (95% CI: 66–70). Children aged 6 to 11 years had lower mean levels of 25(OH)D (66 nmol/L [95% CI: 64–68]) compared with children aged 1 to 5 years (70 nmol/L [95% CI: 68–73]). Overall, the prevalence of levels at <25 nmol/L was 1% (95% CI: 0.7–1.4), <50 nmol/L was 18% (95% CI: 16–21), and <75 nmol/L was 69% (95% CI: 65–73). The prevalence of serum 25(OH)D levels of <75 nmol/L was higher among children aged 6 to 11 years (73%) compared with children aged 1 to 5 years (63%); girls (71%) compared with boys (67%); and non-Hispanic black (92%) and Hispanic (80%) children compared with non-Hispanic white children (59%).

CONCLUSIONS: On the basis of a nationally representative sample of US children aged 1 to 11 years, millions of children may have suboptimal levels of 25(OH)D, especially non-Hispanic black and Hispanic children. More data in children are needed not only to understand better the health implications of specific serum levels of 25(OH)D but also to determine the appropriate vitamin D supplement requirements for children.

METHODS: The study was based on a cross-sectional national telephone survey that involved a target sample of 4549 children aged 0 to 17 years.

RESULTS: A clear majority (60.6%) of the children and youth in this nationally representative sample had experienced at least 1 direct or witnessed victimization in the previous year. Almost half (46.3%) had experienced a physical assault in the study year, 1 in 4 (24.6%) had experienced a property offense, 1 in 10 (10.2%) had experienced a form of child maltreatment, 6.1% had experienced a sexual victimization, and more than 1 in 4 (25.3%) had been a witness to violence or experienced another form of indirect victimization in the year, including 9.8% who had witnessed an intrafamily assault. One in 10 (10.2%) had experienced a victimization-related injury. More than one third (38.7%) had been exposed to 2 or more direct victimizations, 10.9% had 5 or more, and 2.4% had 10 or more during the study year.

CONCLUSIONS: The scope and diversity of child exposure to victimization is not well recognized. Clinicians and researchers need to inquire about a larger spectrum of victimization types to identify multiply victimized children and tailor prevention and interventions to the full range of threats that children face.

METHODS: Through use of the National Electronic Injury Surveillance System database, cases of nonfatal burn-related injuries were selected by using diagnosis codes for burns (scalds, thermal, chemical, radiation, electrical, and not specified). Sample weights were used to calculate national estimates. US Census Bureau data were used to calculate injury rates per 10000 individuals ≤20 years of age. Computation of relative risks with 95% confidence intervals was performed.

RESULTS: An estimated 2054563 patients ≤20 years of age were treated in US emergency departments for burn-related injuries, with an average of 120856 cases per year. Boys constituted 58.6% of case subjects. Children <6 years of age sustained the majority of injuries (57.7%), and more than one half of all injuries (59.5%) resulted from thermal burns. The body parts injured most frequently were the hand/finger (36.0%), followed by the head/face (21.1%). Of the 1542913 cases for which locale was recorded, 91.7% occurred at home. The rate of burn-related injuries per 10000 children decreased 31% over the 17-year time period.

CONCLUSIONS: Burn-related injuries are a serious problem for individuals ≤20 years of age and are potentially preventable. Children <6 years of age consistently sustained a disproportionately large number of injuries during the study period. Increased efforts are needed to improve burn-prevention strategies that target households with young children.

RESULTS: Adults with hydrocephalus need continuous access to expert surgical and medical providers. Existing care models fail to meet this need. The number of young adults who have hydrocephalus, are aged 18 to 35 and need treatment in the United States is predicted to exceed 40000 annually within the next 2 decades. We are developing integrated teams of pediatric and adult medical and surgical specialists to provide continuous, coordinated, comprehensive care for individuals with hydrocephalus in a pediatric setting. This setting will train our future physician workforce on optimal transition care. Coordinated national efforts are also needed.

CONCLUSIONS: Providers need to implement appropriate management and transition care for individuals with hydrocephalus. We must work at local and national levels to transform the care model, improve the quality of health care delivery, and improve outcomes for young adults with hydrocephalus.

METHODS: A multidisciplinary group of specialists with expertise in PHACE syndrome drafted initial diagnostic criteria on the basis of review of published, peer-reviewed medical literature and clinical experience. The group then convened in both executive and general sessions during the PHACE Syndrome Research Conference held in November 2008 for discussion and used a consensus method. All conflicting recommendations were subsequently reconciled via electronic communication and teleconferencing.

RESULTS: These criteria were stratified into 2 categories: (1) PHACE syndrome or (2) possible PHACE syndrome. Major and minor criteria were determined for the following organ systems: cerebrovascular, structural brain, cardiovascular, ocular, and ventral/midline. Definite PHACE requires the presence of a characteristic segmental hemangioma or hemangioma >5 cm on the face or scalp plus 1 major criterion or 2 minor criteria. Possible PHACE requires the presence of a hemangioma >5 cm on the face or scalp plus 1 minor criterion. The group recognized that it may be possible to have PHACE syndrome with a hemangioma affecting the neck, chest, or arm only or no cutaneous hemangioma at all. In such cases, fulfillment of additional required criteria would also lead to a possible PHACE diagnosis.

CONCLUSIONS: These criteria represent current knowledge and are expected to enhance future assessments of PHACE syndrome. It is understood that modifications are to be expected over time to incorporate new research findings.

METHODS: A bibliographic search in the Medline (1967 through July 2008), Embase (1975 through July 2008), and PsycINFO (1967 through July 2008) databases was conducted for studies on breastfeeding and psychotropic medications for a total of 96 drugs. References of retrieved articles, reference books, and dedicated Web sites were also checked. The manufacturers were contacted for drugs without published information. Original articles and review articles that provide pharmacokinetic data on drug excretion in breast milk and infant safety data were considered, to estimate the "compatibility level" of each drug with breastfeeding.

RESULTS: A total of 183 original articles were eligible for analysis. Documentation was retrieved for 62 (65%) drugs. In all, 19 (31%) psychotropic drugs can be used during lactation according to an evidence-based approach. For 28 drugs, the available data do not permit an evaluation of the drug's safety profile during breastfeeding and, for an additional 15 drugs, the exposure dose or observed adverse effects make their use unsafe.

CONCLUSIONS: Although most drugs are considered safe during breastfeeding, compatibility with breastfeeding has not been established for all psychotropic drugs. There is a need for additional research and accumulation of experience to guarantee a more rational use of psychotropic drugs during breastfeeding.

METHODS: We selected 8 symptoms for inclusion in the Strep-PRO. We used the Strep-PRO to assess improvement in children who were aged 5 to 15 years and had confirmed GAS pharyngitis. Children completed the scale at study visits and as a diary at home. To evaluate internal reliability, we examined correlations between the items on the scale. To evaluate construct validity, we examined the correlation at entry between Strep-PRO scores and scores on other, previously validated measures of pain and functional status. To evaluate responsiveness, we examined the change in score from enrollment to follow-up. The correlation between the Strep-PRO score and parental assessment of symptoms was also evaluated.

RESULTS: A total of 131 children were enrolled; 113 returned completed diaries. The internal reliability of the scale was high. The magnitude of correlations between Strep-PRO scores and other measures of pain and functional status ranged from 0.39 to 0.63. The responsiveness of the Strep-PRO was very good. The overall level of agreement between child Strep-PRO scores and parental assessment of symptoms was 0.57.

CONCLUSIONS: The scale seems to measure effectively both pain and overall functional status in children with GAS pharyngitis. These data support the use of Strep-PRO as a measure of outcome in future clinical trials.

METHODS: We used data from a nationally representative cohort of 1116 British families (the Environmental Risk Longitudinal Study). Food insecurity, family SES, maternal mental health and exposure to domestic violence, and children's behavioral outcomes were measured by using validated methods.

RESULTS: Overall, 9.7% of study families were food-insecure. Among low-SES families, controlling for income variation, food insecurity co-occurred with maternal depression (odds ratio [OR]: 2.82 [95% confidence interval (CI): 1.62–4.93]), psychosis spectrum disorder (OR: 4.01 [95% CI: 2.03–7.94]), and domestic violence (OR: 2.36 [95% CI: 1.18–4.73]). In addition, food insecurity predicted elevated rates of children's behavior problems.

CONCLUSIONS: Among families with young children, food insecurity is frequent, particularly when the mother experiences mental health problems. This suggests that interventions that improve women's mental health may also contribute to decreasing the burden of food insecurity and its impact on the next generation.

METHODS: Parents referred to neonatology for prenatal consultation after the diagnosis of a congenital anomaly. Completed 2 qualitative interviews: the first within 1 week of the consultation and the second 1 week after delivery. Interviews were analyzed for themes by using the constant comparative method associated with the grounded theory method.

RESULTS: Thematic saturation was achieved after 42 interviews (22 women); only mothers participated. Five main themes emerged: (1) preparation; (2) knowledgeable physician; (3) caring providers; (4) allowing hope; and (5) time. Mothers believed that a consultation with a neonatologist helped them prepare for the perinatal course. They wished to know the management plan and all possible outcomes. Mothers wanted information specific to their situation and tailored to their knowledge base. Receiving conflicting information from physicians increased anxiety and eroded confidence. Seeing the NICU during the consultation was emotionally difficult but valuable. Mothers wanted realistic information, regardless of how grim, yet wanted to retain hope. All mothers would recommend a prenatal consultation with a neonatologist.

CONCLUSIONS: Mothers perceived that a consultation with a neonatologist, which included a NICU tour, prepared them for the perinatal course. Parents want realistic medical information, specific to their situation, provided in an empathetic manner and want to be allowed to hope for the best possible outcome.

METHODS: A total of 106 newborns who had neonatal seizures and were consecutively admitted to the NICU of the University of Parma from January 1999 through December 2004 were prospectively followed-up, and neurologic outcome was assessed at 24 months’ postconceptional age. We conducted a retrospective analysis on this cohort to identify variables that were significantly related to adverse outcome and to develop a scoring system that could provide early prognostic indications.

RESULTS: A total of 70 (66%) of 106 infants had an adverse neurologic outcome. Six variables were identified as the most important independent risk factors for adverse outcome and were used to construct a scoring system: birth weight, Apgar score at 1 minute, neurologic examination at seizure onset, cerebral ultrasound, efficacy of anticonvulsant therapy, and presence of neonatal status epilepticus. Each variable was scored from 0 to 3 to represent the range from "normal" to "severely abnormal." A total composite score was computed by addition of the raw scores of the 6 variables. This score ranged from 0 to 12. A cutoff score of ≥4 provided the greatest sensitivity and specificity.

CONCLUSIONS: This scoring system may offer an easy, rapid, and reliable prognostic indicator of neurologic outcome after the onset of neonatal seizures. A final assessment of the validity of this score in routine clinical practice will require independent validation in other centers.

METHODS: Participants included 261 children, 2 to 12 years of age, undergoing routine tonsillectomy and adenoidectomy surgery. Baseline and demographic data were collected before surgery, and a standardized approach to anesthesia and surgical procedures was used. Pain and analgesic consumption were recorded for 2 weeks at home.

RESULTS: On the first day at home, although parents rated 86% of children as experiencing significant overall pain, 24% of children received 0 or just 1 medication dose throughout the entire day. On day 3 after surgery, although 67% of children were rated by parents as experiencing significant overall pain, 41% received 0 or 1 medication dose throughout the entire day.

CONCLUSIONS: We conclude that a large proportion of children receive little analgesic medication after surgery and research efforts should be directed to the discrepancy between high ratings of postoperative pain provided by parents and the low dosing of analgesics they use for their children.

METHODS: Patients participated in a longitudinal study of teens with and without probable depression, drawn from 11 primary care offices in Los Angeles, California, and Washington, DC. A total of 4856 teens completed full screening assessments; 4713 were eligible for the study, and 187 (4.0%) met the criteria for probable depression and were invited to participate, as were teens who were not depressed. A total of 184 baseline assessments for teens with probable depression and 184 for nondepressed teens were completed, as were 339 (90%) parent interviews. Follow-up interviews were conducted with 328 teens (89%) and 302 parents (82%). Measures included teen reports of peer and parent support, 2 measures of school functioning, grades, physical health, and days of impairment. Parent reports included peer, school, and family functioning and subjective and objective burdens on parents.

RESULTS: Teens with depression and their parents reported more impairment in all areas, compared with teens without depression at baseline, and reported more coexisting emotional and behavioral problems. Both depression and coexisting problems were related to impairment. There was a lasting impact of depressive symptoms on most measures of peer, family, and school functioning 6 months later, but controlling for coexisting baseline emotional and behavioral problems attenuated this relationship for some measures.

CONCLUSION: Improvements in teen depression might have benefits that extend beyond clinical symptoms, improving peer, family, and school functioning over time.

METHODS: Thirty-six children with cerebral palsy (mean age: 7.7 years; male: 69%; Gross Motor Function Classification System: level I, 47%; level II, 14%; level III, 16%; level IV, 7%; level V, 16%; spasticity, 85%; dyskinesia, 14%; ataxia, 3%) were randomly and equally assigned to OTHPs for 8 or 4 weeks or to no OTHP. The primary end point was Canadian Occupational Performance Measure scores 8 weeks after baseline. Secondary measures were recorded at 4 and 8 weeks.

RESULTS: Eight weeks of OTHP produced statistically significant differences in function and parent satisfaction with function, compared with no OTHP. Parents in the 4-week OTHP group did not discontinue use at 4 weeks, as instructed, and continued for 8 weeks; results demonstrated statistically significant differences, compared with no OTHP. There was no difference in primary or secondary end point measures between intervention groups.

CONCLUSION: Pediatricians can advise families that OTHPs developed with a collaborative, evidence-based approach and implemented by parents at home were clinically effective if implemented 17.5 times per month for an average of 16.5 minutes per session.

METHODS: Data were obtained from the New York State Congenital Malformation Registry (NYS-CMR) in this retrospective cohort study. The occurrence of RUTAs was assessed for children with and without DS who were born in NYS between 1992 and 2004. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for each malformation.

RESULTS: Between 1992 and 2004, 3832 children with DS and 3411833 without DS were born in NYS. The prevalence of RUTAs in the DS population was 3.2%, compared with 0.7% in the NYS population (OR: 4.5 [95% CI: 3.8–5.4]). Children with DS had significantly increased risks of anterior urethral obstruction (OR: 29.7 [95% CI: 4.0–217.7]), cystic dysplastic kidney (OR: 4.5 [95% CI: 1.5–14.1]), hydronephrosis (OR: 8.7 [95% CI: 6.8–11.0]), hydroureter (OR: 8.5 [95% CI: 3.5–20.4]), hypospadias (OR: 2.0 [95% CI: 1.4–2.9]), posterior urethral valves (OR: 7.1 [95% CI: 1.8–28.8]), prune belly syndrome (OR: 11.9 [95% CI: 1.6–85.4]), and renal agenesis (OR: 5.4 [95% CI: 2.8–10.4]). There was no significantly increased risk of ectopic kidney (OR: 1.6 [95% CI: 0.2–11.2]) or ureteropelvic junction obstruction (OR: 1.4 [95% CI: 0.2–9.9]) in the DS population.

CONCLUSION: Children with DS have significantly increased risks of RUTAs.

METHODS: We performed a prospective, randomized, placebo-controlled, multicenter trial. We randomly assigned 243 children with presumed gastroenteritis and vomiting to rectal dimenhydrinate or placebo. Children with no or mild dehydration were included. All children received oral rehydration therapy. Primary outcome was defined as weight gain within 18 to 24 hours after randomization. Secondary outcomes were number of vomiting episodes, fluid intake, parents' assessment of well-being, number of diarrheal episodes, and admission rate to hospital. We recorded potential adverse effects.

RESULTS: Change of weight did not differ between children who received dimenhydrinate or placebo. The mean number of vomiting episodes between randomization and follow-up visit was 0.64 in the dimenhydrinate group and 1.36 in the placebo group. In total, 69.6% of the children in the dimenhydrinate group versus 47.4% in the placebo group were free of vomiting between randomization and the follow-up visit. Hospital admission rate, fluid intake, general well-being of the children, and potential adverse effects, including the number of diarrhea episodes, were similar in both groups.

CONCLUSIONS: Dimenhydrinate reduces the frequency of vomiting in children with mild dehydration; however, the overall benefit is low, because it does not improve oral rehydration and clinical outcome.

METHODS: Charts of 997 patients who were seen in a multidisciplinary ADHD evaluation program were reviewed. Patients who were in first- through sixth-grade and had complete APQ and Wechsler Individual Achievement Test II Basic Reading and Numerical Operations subtests were enrolled in this study. The 271 eligible patients were randomly assigned to a score-development group (n = 215) and a validation group (n = 56). By using data from the score-development sample, APQ questions that predicted low academic achievement were identified and the scores for these questions were entered into a logistic regression to identify the APQ questions that independently predicted low achievement.

RESULTS: Only 2 APQ questions, 1 about reading and 1 about math, independently predicted low achievement. By using these 2 questions, the area under the receiver operating characteristic curve was 0.834, and the optimal combination of sensitivity and specificity occurred when the total score for the 2 items was >4. This cutoff had a sensitivity of 0.86 and a specificity of 0.63 in the score-development group and a sensitivity of 1.0 and a specificity of 0.53 in the validation sample.

CONCLUSIONS: The APQ may be a useful screening tool to identify children being evaluated for ADHD who need additional testing for learning problems. Although the predictive value of a negative screen on the APQ is good, the predictive value of a positive test is relatively low.

METHODS: Parents of 60 children aged 9 to 31 months completed PEDS and ASQ screens at the same visit. Concordance (PEDS and ASQ results agree) and discordance (results differ) for the 2 screens were determined.

RESULTS: The mean age of children was 17.6 months, 77% received Medicaid, and 50% of parents had a high school education or less. Overall, 37% failed the PEDS and 27% failed the ASQ. Thirty-one children passed (52%) both screens; 9 (15%) failed both; and 20 (33%) failed 1 but not the other (13 PEDS and 7 ASQ). Agreement between the 2 screening tests was only fair, statistically no different from agreement by chance.

CONCLUSIONS: There was substantial discordance between PEDS and ASQ developmental screens. Although these are preliminary data, clinicians need to be aware that in implementing revised American Academy of Pediatrics screening guidelines, the choice of screening instrument may affect which children are likely to be identified for additional evaluation.

METHODS: A group of pediatric clinicians and health informatics experts was convened to develop quality indicators reflecting different aspects of the developmental screening process. These indicators included the administration of a standardized, validated instrument to screen children for developmental delays, the documentation of abnormal screening results, and the provision of follow-up care. Six integrated provider systems across the United States, with fully implemented EHR systems, were evaluated to determine the feasibility of implementing these measures within each system. Barriers related to measure implementation were identified.

RESULTS: The EHR systems of all 6 health care organizations could implement measures examining developmental screening rates and could identify and track children with abnormal screening results. However, most of the systems did not have the ability to capture data for more-complex EHR-based measures. In particular, data elements based on workflow actions could not be captured with current EHR system designs.

CONCLUSIONS: This study identified 2 main barriers to the implementation of developmental quality measures: concerns about data reliability and the tracking of care coordination within patient records. Potential solutions to these problems, including terminology standardization, patient portal use, and use of a single developmental screening instrument, are discussed.

METHODS: All very preterm infants who were born at <33 weeks of gestation between January 1, 2003, and July 31, 2004, were hospitalized in the NICU, and survived to discharge were included in this study. Changes in serum sodium levels were measured, and infants were evaluated at corrected age of 2 years.

RESULTS: The analysis involved 237 patients, for whom 3927 serum sodium determinations were performed during the first month of life. We defined 3 tertiles of changes in serum sodium levels. A total of 84 infants demonstrated small changes in serum sodium levels (<8 mEq/L), 86 demonstrated large changes (8–13 mEq/L), and 67 demonstrated very large changes (>13 mEq/L). The reference group was represented by the first tertile. At 2 years of age, large and very large changes in serum sodium levels were significantly associated with risk of impaired functional outcomes, after adjustment for gestational age and perinatal and neonatal hospitalization characteristics (large changes: odds ratio: 3.5 [95% confidence interval: 1.1–11.8]; P = .04; very large changes: odds ratio: 5.1 [95% confidence interval: 1.3–13.6]; P = .02).

CONCLUSIONS: Although large and very large changes in serum sodium levels may simply reflect the severity of illness and/or the quality of care, a causal relationship with outcomes cannot be excluded. Cautious fluid and electrolyte management is recommended for very premature infants.

METHODS: Maternal (delivery; N = 53) and neonatal (cord; N = 52) serum S100B levels were compared between prenatally SSRI-exposed (maternal, N = 36; neonatal, N = 37; duration: 230 ± 71 days) and nonexposed (maternal, N = 17; neonatal, N = 15) groups. Measures of maternal depression and anxiety symptoms were assessed during the third trimester (33–36 weeks), and neonatal outcomes, including Apgar scores, birth weight, gestational age at birth, and symptoms of poor neonatal adaptation, were recorded.

RESULTS: S100B levels were significantly lower in prenatally SSRI-exposed neonates than in nonexposed neonates, controlling for gestational age and third-trimester maternal mood (P = .036). In contrast, SSRI-exposed mothers had significantly higher maternal serum S100B levels, compared with nonexposed mothers (P = .014), even controlling for maternal mood in the third trimester. S100B levels were not associated with maternal or neonatal drug levels, duration of prenatal exposure, demographic variables, or risk for poor neonatal adaptation.

CONCLUSIONS: Prenatal SSRI exposure was associated with decreased neonatal serum S100B levels, controlling for prenatal maternal mood. Neonatal S100B levels did not reflect neonatal behavioral outcomes and were not related to pharmacologic indices. These findings are consistent with prenatal alcohol and cocaine exposures, which also alter central serotonin levels.

METHODS: In a randomized, controlled trial conducted in 2001–2004 in Washington, DC, 714 women (126 active smokers [18%]) were tested for SCLs at the time of recruitment and later in pregnancy. Sociodemographic health risks and pregnancy outcomes were recorded.

RESULTS: Birth weights were significantly lower for infants born to mothers with baseline SCLs of ≥20 ng/mL in comparison with <20 ng/mL (P = .024), ≥50 ng/mL in comparison with <50 ng/mL (P = .002), and ≥100 ng/mL in comparison with <100 ng/mL (P = .002), in bivariate analyses. In linear regression analyses adjusting for sociodemographic and medical factors, SCLs of ≥20 ng/mL were associated with a reduction in birth weight of 88 g when SCLs were measured at baseline (P = .042) and 205 g when SCLs were measured immediately before delivery (P < .001). Corresponding results were 129 g (P = .006) and 202 g (P < .001) for ≥50 ng/mL and 139 g (P = .007) and 205 g (P < .001) for ≥100 ng/mL. Gestational age was not affected significantly at any SCL, regardless of when SCLs were measured.

CONCLUSIONS: Elevated SCLs early in pregnancy or before delivery were associated with reductions in birth weight. At any cutoff level, birth weight reduction was more significant for the same SCL measured in late pregnancy. Maintaining lower levels of smoking for women who are unable to quit may be beneficial.

METHODS: This was a retrospective cohort study with a data set for a group (N = 366) of infants of <1500 g and ≤30 weeks of gestation that was created initially to examine the association between rEPO treatment and retinopathy of prematurity. Infants who underwent developmental follow-up evaluations at corrected age of >12 months were included. The associations between rEPO doses and higher Bayley Scales of Infant Development Psychomotor Developmental Index and Mental Developmental Index (MDI) scores were estimated in multivariate linear regression analyses.

RESULTS: Eighty-two infants underwent developmental evaluations after 12 months. The median age of evaluation was 25 months. The median 6-week cumulative rEPO dose was 3750 U/kg. In multivariate analyses, Psychomotor Developmental Index (PDI) scores were associated with transfusions, female gender, birth weight, and 5-minute Apgar scores (R² = 0.39). MDI scores were associated with 6-week rEPO dose, female gender, prenatal steroid treatment for ≥48 hours, and breast milk feedings (R² = 0.40).

CONCLUSIONS: These findings identify a dose-response relationship between rEPO treatment and improved MDI scores. They are consistent with findings of adult studies and animal brain injury models and await confirmation.

METHODS: A retrospective analysis of the Nationwide Inpatient Sample (1988–2005) was performed, with additional factors incorporated from the Area Resource File (2006). International Classification of Diseases, Ninth Revision, diagnosis/procedure coding was used to identify patients. High-volume centers were defined as those with ≥50 neurosurgical cases per year. Patients >18 years of age were excluded. Covariates included age, gender, race, Charlson Index score, insurance, and county-level characteristics (including median home value, proportion of foreign born residents, and county neurosurgeon density). Multivariate analysis was performed by using multiple logistic regression models. P values of <.05 were considered statistically significant.

RESULTS: A total of 4421 patients were identified; 1651 (37.34%) were admitted to high-volume centers. Overall access to high-volume centers improved slightly over the 18-year period (odds ratio [OR]: 1.04). Factors associated with greater access to high-volume centers included greater county neurosurgeon density (OR: 1.72) and greater county home value (OR: 1.66). Factors associated with worse access included Hispanic ethnicity (OR: 0.68) and each 1% increase in foreign residents per county (OR: 0.59). All reported P values were <.05.

CONCLUSION: This study demonstrates that racial and socioeconomic disparities in access to high-volume neurooncological care exist for the pediatric population. We also identify numerous prehospital factors that potentially contribute to persistent disparities and may be amenable to change through national health policy interventions.

METHODS: Children <18 years of age who presented to an urban pediatric emergency department or were transferred from a referral hospital within 6 hours after accidental closed head trauma and who underwent cranial computed tomography were enrolled prospectively. Mean serum S100B levels for children with or without intracranial injury (ICI) and long-bone fractures were evaluated through analysis of covariance.

RESULTS: One hundred fifty-two children, 24 with ICI and 128 without ICI, were enrolled prospectively. Twenty-five children had long-bone fractures. Children with ICI were significantly younger than those without ICI (6.9 vs 9.8 years; P = .01). The time of venipuncture after injury was significantly later in children with ICI (P = .03). Mean S100B levels were significantly greater for children with ICI (212.9 vs 84.4 ng/L; P = .001), children with long-bone fractures (P = .008), and nonwhite children (P = .03). After controlling for time of venipuncture, long-bone fractures, and race, mean S100B levels were still greater for children with ICI (409 vs 118 ng/L; P = .001). The ability of serum S100B measurements to detect ICI, determined as the area under the curve, was 0.67.

CONCLUSIONS: After controlling for time of venipuncture, long-bone fractures, and race, S100B levels were still higher in children with ICI than in those without ICI. However, the ability of serum S100B measurements to detect ICI was poor.

METHODS: Focus groups were held with (1) mothers of young children with typical development, (2) mothers of young children who received EI services, and (3) EI specialists. Seven groups (N = 46 participants) were conducted in the greater Cleveland, Ohio, area. Meetings were audio-recorded, transcribed, coded, and analyzed, to identify themes.

RESULTS: Most mothers reported a preference for a nonalarmist style of communication when developmental delays are suspected. In contrast, some mothers preferred a more direct style, including the use of labels to help them understand their child's development. The importance of preparation to accept information about developmental delays emerged as a theme in all groups. Elements contributing to preparedness included information about expected developmental skills, suggestions for promoting skills, and a specific time frame for follow-up evaluation. Mothers of children with disabilities perceived that early reassurance of normalcy by providers in response to their concerns led to self-doubt and increased difficulty accepting the diagnosis.

CONCLUSIONS: Mothers and EI specialists have clear ideas about factors that promote or impede communication regarding child development. This information can inform primary care providers' approaches to monitoring and screening the development of young children and to communicating with parents regarding suspected developmental delays.

METHODS: We prepared a computerized, interactive curriculum, Enhancing Proficiency in Otitis Media (ePROM), that was centered around assemblages of clinically diverse, still and video images of tympanic membranes (TMs). To assess curriculum effectiveness, we constructed a test, the Diagnostic Ear Assessment Resource, that consisted of 50 video TM images. We administered the test to 84 residents in pediatrics or family practice who had not been exposed to ePROM and, varying the order in which the images were presented, to another group of 102 residents in the same programs both before and after exposure to ePROM.

RESULTS:o Mean proportions of correct diagnoses in the Diagnostic Ear Assessment Resource were larger among residents who had been exposed to ePROM than among residents at comparable levels of training who had not been exposed (67% vs 62%; P = .007). Among residents exposed to ePROM, mean proportions of correct diagnoses were larger after exposure than before (67% vs 55%; P < .001).

CONCLUSION: A structured, computerized curriculum to supplement standard clinical training can enhance residents' abilities to interpret still and video images of TMs and may improve their skills in diagnosing otitis media.

METHODS: Complete clinical and genetic information was available for 393 children with periodic fever; 82 had positive genetic test results, 75 had incomplete genetic test results, and 236 had negative results for MVK, TNFRSF1A, and MEFV mutations. Current diagnostic criteria for PFAPA syndrome were applied.

RESULTS: Of 393 children, 210 satisfied PFAPA syndrome criteria; 43 carried diagnostic mutations (mevalonate kinase deficiency: n = 33; tumor necrosis factor receptor-associated periodic syndrome: n = 3; familial Mediterranean fever: n = 7), 37 displayed low-penetrance mutations or incomplete genotypes, and 130 demonstrated negative genetic testing results. Genetically positive patients had higher frequencies of abdominal pain and diarrhea (P < .001), vomiting (P = .006), and cutaneous rash and arthralgia (P = .01). Genetically negative patients had a higher frequency of exudative pharyngitis (P = .010). Genetically undetermined patients showed the same pattern of symptom frequency as genetically negative patients. The Gaslini diagnostic score was able to identify 91% of genetically positive patients correctly, with a global accuracy of 66%.

CONCLUSION: The Gaslini diagnostic score represents a useful tool to identify patients meeting PFAPA syndrome criteria and at low risk of carrying relevant mutations in genes associated with periodic fevers.

PATIENTS AND METHODS: We performed a prospective, single-blinded study including 227 participants, comprising 131 parents, 58 nurses, and 38 doctors. Participants visually estimated the volume of 1 randomly allocated sample from each of the 2 categories: (1) 1, 5, or 10 mL of artificial blood applied to a diaper (simulated hematochezia) and (2) 5, 10, or 50 mL placed in a kidney-dish (simulated hematemesis). An "error factor" (=, estimated volume/actual volume shown) was used to facilitate comparisons.

RESULTS: Parents provided the most inaccurate estimates overall, although individual accuracy varied considerably. The largest overestimate (518 mL) and the highest error factor (23.4) were recorded in a parent; overall, 71% of the estimates provided by parents were overestimates. The highest proportion of accurate estimates (±50% of actual volume) was recorded by nurses (29%). Doctors had a tendency to underestimate volumes (62% of the estimates were less than half the actual volume). However, there was no statistically significant difference between the performance of nurses and doctors. Health care professionals tended to overestimate small volumes and underestimate large volumes. Professional experience had no relevant impact on accuracy, nor did parental gender or age.

CONCLUSIONS: Visual estimation of blood losses is highly inaccurate, both by laypersons and by health care professionals. Physicians should, therefore, base management decisions primarily on clinical findings and not overly rely on the history provided, or their own estimates.

PATIENT AND METHODS: Information on asthma, zygosity, birth characteristics, and potential confounders was collected for all 9- and 12-year-old twins through the Swedish Twin Register and Medical Birth Register. To obtain an overall effect of birth weight on risk of asthma, we performed cohort analyses on all twins (N = 10918). To address genetic and shared environmental confounding, we performed a co-twin control analysis by using the 157 monozygotic and 289 dizygotic same-sex twin pairs who were discordant for asthma.

RESULTS: The overall rate of asthma ever was 13.7%. In the cohort analysis, the adjusted odds ratio (OR) for asthma in relation to a 1000-g decrease in birth weight was 1.57 (95% confidence interval [CI]: 1.38–1.79), and for each reduced gestational week the OR was 1.10 (95% CI: 1.07–1.13). In the co-twin control analyses, a 1000-g decrease in birth weight corresponded to an OR of 1.25 (95% CI: 0.74–2.10) for dizygotic same-sex twins and 2.42 (95% CI: 1.00–5.88) for monozygotic twins.

CONCLUSIONS: There is an association between fetal growth and childhood asthma that is independent of GA and shared (familial) environment and genetic factors, which indicates that fetal growth restriction affects lung development, supporting additional studies on the early metabolic and physiologic mechanisms of childhood asthma.

METHODS: Data were obtained from the National Center for Health Statistics, which collects information on patient visits to outpatient clinics and emergency departments throughout the United States. We analyzed data for children 0 to 18 years of age seeking medical treatment for an ADE between 1995 and 2005.

RESULTS: The mean annual number of ADE-related visits was 585922 (95% confidence interval [CI]: 503687–668156) of which 78% occurred in outpatient clinics and 12% occurred in emergency departments. Children 0 to 4 years of age had the highest incidence of ADE-related visits, accounting for 43.2% (95% CI: 35.6%–51.2%) of visits. The most common symptom manifestations were dermatologic conditions (45.4% [95% CI: 36.9%–54.1%]) and gastrointestinal symptoms (16.5% [95% CI: 11.1%–23.8%]). The medication classes most frequently implicated in an ADE were antimicrobial agents (27.5% [95% CI: 21.5%–34.5%]), central nervous system agents (6.5% [95% CI: 4.0%–10.5%]), and hormones (6.1% [95% CI: 3.1%–11.6%]). While ADEs related to antimicrobial agents were most common among children 0 to 4 years old and decreased in frequency among older children, ADEs resulting from central nervous system agents and hormones increased in frequency among children 5 to 11 and 12 to 18 years old.

CONCLUSIONS: ADEs result in a substantial number of health care visits, particularly in outpatient clinics. The incidence of ADEs and medications implicated vary by age, indicating that age-specific approaches for monitoring and preventing ADEs may be most effective.

OBJECTIVE: Our goal was to review systematically all available evidence regarding how physicians should approach the conversation in which they explain DS for the first time to new parents.

METHODS: We searched online databases from 1960 to 2008, including Medline and PsychInfo, as well as Web sites maintained by academic organizations (eg, American Academy of Pediatrics) and other nonprofit or private organizations (eg, the National Down Syndrome Society), by using the terms "Down syndrome," "trisomy 21," "mongolism," "prenatal diagnosis," "postnatal care," and "delivery of health care." Articles were selected that answered ≥1 research question, established a priori: (1) Who is the best person to communicate the news? (2) When is the best time to share the news? (3) Where is the best place or setting to deliver the news? (4) What information should be delivered? and (5) How should the news be communicated? All studies were evaluated for quality according to the method outlined by the US Preventative Services Task Force. Final recommendations were based on the strength of evidence.

RESULTS: Parents prefer to receive the diagnosis together in a joint meeting with their obstetrician and pediatrician. The conversation should take place in a private setting as soon as a physician suspects a diagnosis of DS. Accurate and up-to-date information should be conveyed, including information about local support groups and resources.

CONCLUSION: By implementing a few cost-neutral measures, physicians can deliver a postnatal diagnosis of DS in a manner that will be deemed by new parents as sensitive and appropriate.

METHODS: The study was performed in Umeå, a university city in Sweden. All children in grades 3 and 6 were invited, and 97% participated (313 girls and 292 boys in grade 3 [mean age: 9.7 years]; 386 girls and 464 boys in grade 6 [mean age: 12.6 years]). Pain and HRQoL were measured with questionnaires.

RESULTS: Two thirds of the children reported recurrent pain (at least monthly). One third reported weekly pain, and 4 of 10 experienced pain from multiple locations. HRQoL impairment was twice as common among children with recurrent pain, compared with children without pain. All aspects of HRQoL (ie, physical, emotional, social, and school functioning and well-being) were impaired. The level of impairment was classified as considerable, especially for children who experienced pain from multiple body sites and children with weekly pain (Cohen's d = 0.6–0.8).

CONCLUSIONS: This study shows that young schoolchildren with recurrent pain have considerable impairment of their HRQoL.

METHODS: Records for infants with LRTI as a cause of death were examined by using the linked birth/infant death database for 1999–2004. Singleton infants dying with LRTI and a random sample of surviving singleton infants were compared for selected characteristics.

RESULTS: A total of 5420 LRTI-associated infant deaths were documented in the United States during 1999–2004, for an LRTI-associated infant mortality rate of 22.3 per 100000 live births. Rates varied according to race; the rate for American Indian/Alaska Native (AI/AN) infants was highest (53.2), followed by black (44.1), white (18.7), and Asian/Pacific Islander infants (12.3). Singleton infants with low birth weight (<2500 g) were at increased risk of dying with LRTI after controlling for other characteristics, especially black infants. Both AI/AN and black infants born with a birth weight of ≥2500 g were more likely to have died with LRTI than other infants of the same birth weight. Other risk factors associated with LRTI infant death included male gender, the third or more live birth, an Apgar score of <8, unmarried mother, mother with <12 years of education, mother <25 years of age, and mother using tobacco during pregnancy.

CONCLUSIONS: Low birth weight was associated with markedly increased risk for LRTI-associated death among all of the racial groups. Among infants with a birth weight of ≥2500 g, AI/AN and black infants were at higher risk of LRTI-associated death, even after controlling for maternal and birth-related factors. Additional studies and strategies should focus on the prevention of maternal and birth-related risk factors for postneonatal LRTI and on identifying additional risk factors that contribute to elevated mortality among AI/AN and black infants.

Methods: Eighty children (4–10 years of age) and their guardians were recruited from a pediatric emergency department. A survey and color photographs of the same male and female physicians wearing face shields and surgical masks were distributed. The parents were asked to decide which set of physicians they would prefer to care for their children and with which set of physicians they thought their children would be most comfortable. The children then were asked to decide which set of physicians they would prefer to take care of them and why. The children also were asked whether they found any of the physicians frightening and, if so, why.

Results: Fifty-one percent of parents preferred the pictures of physicians wearing face shields, and 62% thought that their children would choose the physicians in the face shields because their faces were visible and therefore less frightening. However, 59% of children stated that either set of physicians would be fine and neither was frightening; if given a choice, 49% would choose physicians in face shields.

Conclusions: Physicians and parents have a perception that surgical masks are frightening to all children. Our study has shown that this perception is not completely true. Face shields may be a better choice, however, because both parents and children would prefer this option.

METHODS: A literature search of interventions was conducted of 14 electronic databases. Three reviewers independently evaluated studies to determine whether they met the inclusion criteria. Studies were compared on 5 components: design, methodologic quality, intervention components, efficacy, and alignment with the Consolidated Standard of Reporting Trials (CONSORT) and Transparent Reporting of Evaluation with Nonrandomized Designs (TREND) statements.

RESULTS: Seventeen studies met the inclusion criteria. More than half (65%) were controlled trials and delivered at child care settings or schools (65%). Three studies had high methodologic quality. Studies were ~12 weeks in duration and delivered by teachers, researchers, and students. Parents were involved in only 3 studies. Nearly 60% of the studies reported statistically significant improvements at follow-up. Three studies aligned with the CONSORT and TREND statements.

CONCLUSIONS: This review highlights the limited quantity and quality of interventions to improve motor development in young children. The following recommendations are made: (1) both teachers and researchers should be involved in the implementation of an intervention; (2) parental involvement is critical to ensuring transfer of knowledge from the intervention setting to the home environment; and (3) interventions should be methodologically sound and follow guidelines detailed in the CONSORT or TREND statement.

METHODS: A retrospective cohort study of patients <18 years of age who were discharged from 35 to 40 children's hospitals (depending on the year) across the United States in 2001–2007 was performed. By using the Pediatric Health Information System administrative database, cases were assessed for discharge diagnosis codes for VTE; the use of anticoagulants was assessed by using patient-specific pharmacy files.

RESULTS: During the 7-year study period, in which 11337 hospitalized patients were diagnosed with VTE, the annual rate of VTE increased by 70%, from 34 to 58 cases per 10000 hospital admissions (P < .001). This increase was observed in neonates, infants, children, and adolescents. The majority (63%) of children with VTE had ≥1 coexisting chronic complex medical condition. Pediatric malignancy was the medical comorbid condition associated most strongly with recurrent VTE (P < .001). The proportion of children with VTE who were treated with enoxaparin increased from 29% to 49% during this time period (P < .001); the use of warfarin decreased slightly from 11.4% to 9.6% (P = .02). Increasing age was associated with increased likelihood of patients with VTE being treated with either enoxaparin or warfarin.

CONCLUSION: This multicenter study demonstrates a dramatic increase in the diagnosis of VTE at children's hospitals from 2001 to 2007.

METHODS: This cluster-randomized, controlled trial took place in a large NICU in Canada, with follow-up evaluation at 18 months of age, from September 1999 to September 2004. One hundred VLBW singleton infants and 10 VLBW twin sets were assigned randomly to NIDCAP-based or control care, and 90% participated in follow-up assessments. The intervention was NIDCAP-based care (N = 56), that is, care by NIDCAP-educated staff members and behavioral observations. The control group (N = 55) received standard NICU care. Statistical analyses were adjusted for cluster randomization. Although the intervention was not blinded, the pediatricians making the decisions to discharge the infants were not involved in the study, and the follow-up staff members were blinded with respect to group.

RESULTS: NIDCAP group infants had reduced length of stay (median: NIDCAP: 74 days; control: 84 days; P = .003) and incidence of chronic lung disease (NIDCAP: 29%; control: 49%; odds ratio: 0.42 [95% confidence interval: 0.18–0.95]; P = .035). At 18 months of adjusted age, NIDCAP group infants had less disability, specifically mental delay (NIDCAP: 10%; control: 30%; odds ratio: 0.25 [95% confidence interval: 0.08–0.82]; P = .017).

CONCLUSION: NIDCAP-based care for VLBW infants improved short- and long-term outcomes significantly.

METHODS: Infants were assigned randomly, within 48 hours after birth, to a NIDCAP group or basic developmental care (control) group. The NIDCAP intervention consisted of weekly formal behavioral observations of the infants and caregiving recommendations and support for staff members and parents, as well as incubator covers and positioning aids. The control group infants were given basic developmental care, which consisted of only incubator covers and positioning aids. Outcome measures were respiratory support, intensive care, and weight of <1000 g. Growth parameters were measured weekly or biweekly and at term age. Neuromotor development was assessed at term age.

RESULTS: A total of 164 infants met the inclusion criteria (NIDCAP: N = 81; control: N = 83). In-hospital mortality rates were 8 (9.9%) of 81 infants in the NIDCAP group and 3 (3.6%) of 83 infants in the control group. No differences in mean days of respiratory support (NIDCAP: 13.9 days; control: 16.3 days) or mean days of intensive care (NIDCAP: 15.2 days; control: 17.0 days) were found. Short-term growth and neuromotor development at term age showed no differences, even with correction for the duration of the intervention.

CONCLUSIONS: NIDCAP developmental care had no effect on respiratory support, days of intensive care, growth, or neuromotor development at term age.

METHODS: In this retrospective cohort study of 358086 infants of ≥35 weeks and ≥2000 g born between January 1, 1995, and June 30, 2007, we obtained demographic data, bilirubin levels, and codes for inpatient phototherapy from existing databases. We compared the incidence of high total serum bilirubin (TSB) levels and phototherapy before and after implementation of universal screening and examined risk factors for high TSB levels.

RESULTS: A total of 38182 infants (10.6%) were born at facilities that had implemented universal bilirubin screening. Compared with infants born at facilities that were not screening, these infants had a 62% lower incidence of TSB levels exceeding the American Academy of Pediatrics exchange guideline (0.17% vs 0.45%; P < .001), received twice the inpatient phototherapy (9.1% vs 4.2%; P < .001), and had slightly longer birth hospitalization lengths of stay (50.9 vs 48.7 hours; P < .001). Of those receiving phototherapy, 56% after initiation of universal screening had TSB levels at which phototherapy was recommended by the guideline, compared with 70% before screening. The adjusted odds ratio for developing TSB levels exceeding the guideline value was 0.28 (95% confidence interval: 0.20–0.40) for those born at a facility using TSB screening and 0.28 (95% confidence interval: 0.19–0.42) for those born at a facility using transcutaneous bilirubin screening.

CONCLUSIONS: Universal bilirubin screening was associated with a significantly lower incidence of severe hyperbilirubinemia but also with increased phototherapy use.

METHODS: The 2006 National Young Driver Survey gathered data on driving safety behaviors from a nationally representative sample of 5665 ninth-, 10th-, and 11th-graders. A parenting style variable was based on adolescent reports and separated parents into 4 groups, (1) authoritative (high support and high rules/monitoring), (2) authoritarian (low support and high rules/monitoring), (3) permissive (high support and low rules/monitoring), and (4) uninvolved (low support and low rules/monitoring). Associations between parenting style and driving behaviors and attitudes were assessed.

RESULTS: One half of parents were described as authoritative, 23% as permissive, 8% as authoritarian, and 19% as uninvolved. Compared with teens with uninvolved parents, those with authoritative parents reported one half the crash risk in the past year (odds ratio [OR]: 0.47 [95% confidence interval [CI]: 0.26–0.87]), were 71% less likely to drive when intoxicated (OR: 0.29 [95% CI: 0.19–0.44]), and were less likely to use a cellular telephone while driving (OR: 0.71 [95% CI: 0.50–0.99]). Teens with authoritative or authoritarian parents reported using seat belts nearly twice as often (authoritative: OR: 1.94 [95% CI: 1.49–2.54]; authoritarian: OR: 1.85 [95% CI: 1.08–3.18]) and speeding one half as often (authoritative: OR: 0.47 [95% CI: 0.36–0.61]; authoritarian: OR: 0.63 [95% CI: 0.40–0.99]) as teens with uninvolved parents. No significant differences in crash risk or seat belt use were found between permissive and uninvolved parents.

CONCLUSIONS: Clinicians should encourage parents to set rules and to monitor teens' driving behaviors, in a supportive context.

METHODS: A total of 10382 TcB measurements were performed with 2039 healthy neonates (gestational age of ≥35 weeks and birth weight of ≥2000 g), with a BiliCheck bilirubinometer (SpectRx, Norcross, GA), at designated time points between 12 and 120 hours of life. According to their severity, these TcB measurements were selectively cross-checked with a direct spectrophotometric device, and significant hyperbilirubinemia was defined on the basis of the hour-specific threshold values for phototherapy proposed by the American Academy of Pediatrics. With the use of likelihood ratios (LRs), the high- and low-risk demarcators for each designated time were calculated and presented on an hour-specific nomogram.

RESULTS: Significant hyperbilirubinemia was documented for 122 neonates (6%). At 24 hours of life, the high-risk zone of the nomogram had 73.9% sensitivity and a positive LR of 12.1 in predicting significant hyperbilirubinemia, whereas the low-risk zone had 97.7% sensitivity and a negative LR of 0.04. At 48 hours, the high-risk zone had 90% sensitivity and a positive LR of 12.1, whereas the low-risk zone had 98.8% sensitivity and a negative LR of 0.02. In our study population, the probability of significant hyperbilirubinemia would be >35% for values in the high-risk zone and <0.5% for values in the low-risk zone of the nomogram.

CONCLUSIONS: We provide a predictive TcB tool that could allow for a noninvasive, risk-based approach to neonatal hyperbilirubinemia.

METHODS: Participants were 192 children 8.0 to 12.0 years of age (mean ± SD: 10.2 ± 1.2 years). The average BMI percentile for age and gender was 99.18 (SD: 0.72). Families were assigned randomly to the intervention or usual care. Assessments were conducted at baseline, 6 months, 12 months, and 18 months. The primary outcome was percent overweight (percent over the median BMI for age and gender). Changes in blood pressure, body composition, waist circumference, and health-related quality of life also were evaluated. Finally, we examined factors associated with changes in child percent overweight, particularly session attendance.

RESULTS: Intervention was associated with significant decreases in child percent overweight, relative to usual care, at 6 months. Intent-to-treat analyses documented that intervention was associated with a 7.58% decrease in child percent overweight at 6 months, compared with a 0.66% decrease with usual care, but differences were not significant at 12 or 18 months. Small significant improvements in medical outcomes were observed at 6 and 12 months. Children who attended ≥75% of intervention sessions maintained decreases in percent overweight through 18 months. Lower baseline percent overweight, better attendance, higher income, and greater parent BMI reduction were associated with significantly greater reductions in child percent overweight at 6 months among intervention participants.

CONCLUSIONS: Intervention was associated with significant short-term reductions in obesity and improvements in medical parameters and conferred longer-term weight change benefits for children who attended ≥75% of sessions.

METHODS: A nationally representative, school-based survey of 2167 ninth-, 10th-, and 11th-graders examined patterns of vehicle access (primary access [ie, the teen is the main driver of the vehicle] versus shared access) and associated driving exposure, risky driving behaviors, and sociodemographic factors.

RESULTS: Seventy percent of drivers reported having primary access to vehicles. They were more likely to be white, to be in 11th grade, to attend schools with higher socioeconomic levels, to have mostly A/B grades, to have a job, to drive a pickup truck, and to drive more hours per week but were not more or less likely to consume alcohol or to wear seat belts while driving. Compared with drivers with shared access, drivers with primary access reported more than twice the crash risk (risk ratio [RR]: 2.05 [95% confidence interval [CI]: 1.41–2.99]) and higher likelihoods of using cellular telephones while driving (RR: 1.23 [95% CI: 1.12–1.35]) and speeding ≥10 mph above the posted limit (RR: 1.24 [95% CI: 1.11–1.40]).

CONCLUSIONS: Primary access of novice teen drivers to vehicles is highly prevalent in the United States. This practice is a dangerous norm, because primary access is associated with risky driving behaviors. Healthcare providers and schools should consider counseling parents to discourage giving novice teen drivers primary access to vehicles. In communities where teens require primary access (eg, due to limited public transportation options), greater efforts should be made to promote safe behaviors.

METHODS: We surveyed health care providers regarding their knowledge and beliefs about HIV and generated a protocol for routine HIV screening. Free, routine, opt-out, HIV screening was offered for all adolescents (13–18 years of age) presenting for care in the ED. We studied ED HIV screening rates, rates of test acceptance among patients/guardians, patients' reasons for opting out, and HIV prevalence. A computerized prompt in the electronic chart was introduced 5 months after initiation, to address low screening rates.

RESULTS: Of the 118 health care providers who responded to the preimplementation survey, 78% were unaware of the revised HIV testing guidelines and 58% predicted that routine screening would fail because of patient or guardian refusal. Of the 5399 patients who qualified for routine screening, 37% (2002) were offered opt-out screening. Of those, 13% opted out. Patients offered screening were more likely than patients not offered screening to be older (≥15 years; P = .002), female (P = .003), and nonwhite (P = .006). Older patients (≥15 years of age) who were approached for screening were less likely to opt out (P = .002). Computerized prompting improved screening rates. One of the 1735 tests (0.57 per 1000 tests) performed yielded positive results for HIV.

CONCLUSION: Adolescents and their guardians accept routine, opt-out, HIV screening, regardless of gender or race, and a computerized reminder enhances screening.

METHODS: We conducted a longitudinal cohort study in which 45 of 62 eligible children with OCD were reassessed an average of 9 years later, in early adulthood. Main outcome measures included expert-rated, obsessive-compulsive (OC) symptom severity and time to remission of OC symptoms. Baseline clinical characteristics were evaluated in terms of their influence on OCD severity in adulthood and time to remission of OC symptoms.

RESULTS: Forty-four percent of subjects were determined to have subclinical OC symptoms at the follow-up evaluation. The absence of a comorbid tic disorder and the presence of prominent hoarding symptoms were associated with the persistence of OCD symptoms. Female gender, earlier age at childhood assessment, later age of OCD onset, more-severe childhood OCD symptoms, and comorbid oppositional defiant disorder also were associated with persistence of OCD symptoms into adulthood.

CONCLUSIONS: These results confirm that a significant proportion of treated children with OCD experience remission by adulthood. The presence of comorbid tics heralds a positive outcome, whereas primary hoarding symptoms are associated with persistent OCD.

METHODS: Eight 90-minute focus groups (4 parent groups and 4 family advocate groups) were conducted at 2 Head Start centers. Each discussion was audiotaped, transcribed, and analyzed for major themes.

RESULTS: A total of 63 adults (38 family advocates [92% female] and 25 parents [100% female]) participated in the 8 groups. Family advocates and parents agreed that Head Start was an important source of parenting advice and of referrals to community resources. Connected Kids topics were well received, although potential parental resistance to gun safety and discipline materials was identified. The positive nature of the advice was important to both types of groups. Brochures were generally well liked, but all groups thought that they should be linked directly to community resource information and offered as part of tailored education. Various venues for curriculum use were suggested, and formats involving multiple media were requested. Although Head Start serves preschool-aged children, parents and family advocates valued access to the full range of Connected Kids materials (for ages 0–18 years). Family advocates emphasized that supplementary materials on background information and delivery methods would be essential for effective implementation of Connected Kids at Head Start.

CONCLUSIONS: Head Start family advocates and parents found the Connected Kids curriculum desirable. Although modifications might improve its usefulness, the curriculum seems acceptable and appropriate for the Head Start environment.

METHODS: An online survey was conducted with 1000 parents selected to be demographically representative of the US population. Questions explored awareness of, knowledge of, and attitudes toward growth monitoring, as well as the ability to interpret growth chart data.

RESULTS: Seventy-nine percent of parents surveyed claimed to have seen a growth chart before, with the majority thinking that they understood it well. Sixty-four percent of parents thought it was important to be shown growth charts to see how their child was growing, and 40% expressed the need to see their child's growth chart as confirmation of their health care provider's verbal interpretation. However, when provided with multiple-choice questions and answers, only 64% could identify a child's weight when shown a plotted point on a growth chart. Ninety-six percent had heard of the term "percentile," but only 68% identified the percentile of the plotted point, and only 56% could identify the definition of percentile. Up to 77% interpreted incorrectly charts containing height/weight measurements in tandem.

CONCLUSIONS: Although growth charts are used frequently as visual aids to educate parents about their children's growth, many parents cannot comprehend the data. This finding is significant because many parents prefer to be shown growth charts by their health care provider, and many parents report recording their children's measurements on growth charts at home.

METHODS: We examined 847 students, 13 to 18 years of age, who had attended outdoor or indoor chlorinated pools at various rates. Of them, 114 had attended mainly a copper-silver pool and served as a reference group. We measured total and aeroallergen-specific immunoglobulin E (IgE) levels in serum and screened for exercise-induced bronchoconstriction. Outcomes were respiratory symptoms, hay fever, allergic rhinitis, and asthma that had been diagnosed at any time (ever asthma) or was being treated with medication and/or was associated with exercise-induced bronchoconstriction (current asthma).

RESULTS: Among adolescents with atopy with serum IgE levels of >30 kIU/L or aeroallergen-specific IgE, the odds ratios (ORs) for asthma symptoms and for ever or current asthma increased with the lifetime number of hours spent in chlorinated pools, reaching values of 7.1 to 14.9 when chlorinated pool attendance exceeded 1000 hours. Adolescents with atopy with chlorinated pool attendance of >100 hours had greater risk of hay fever (OR: 3.3-6.6), and those with attendance of >1000 hours had greater risk of allergic rhinitis (OR: 2.2-3.5). Such associations were not found among adolescents without atopy or with copper-silver pool attendance. The population attributable risks for chlorinated pool-related ever-diagnosed asthma, hay fever, and allergic rhinitis were 63.4%, 62.1%, and 35.0%, respectively.

CONCLUSION: Chlorinated pool exposure exerts an adjuvant effect on atopy that seems to contribute significantly to the burden of asthma and respiratory allergies among adolescents.

METHODS: This was an observational study of a convenience sample of morning work rounds in a PICU, followed by surveys of family members of patients in the unit and residents who had been present for rounds.

RESULTS: A total of 411 patient encounters were observed, 98 family questionnaires were fully completed, and 33 resident questionnaires were completed. Ninety-eight percent of family members liked to be present for rounds. On the first day of admission, family members were less likely to understand the plan (P = .03), to feel comfortable asking questions (P = .007), or to want bad news during rounds (P = .009). They were more likely to have privacy concerns (P = .02) and to want 1 individual to convey the plan after rounds (P = .01). Higher education level was associated with decreased privacy concerns (P = .002) but did not affect understanding of the plan. Fifty-two percent of residents perceived that teaching was decreased with families present. Time spent with individual patients was not increased by family member presence (P = .12).

CONCLUSIONS: Family satisfaction is high, but families of patients on the first day of admission may need special attention. The medical team should conduct rounds in a manner that addresses the privacy concerns of families. Residents often think that teaching is decreased when families are present.

OBJECTIVE: Our objective for this study was to evaluate the outcome of the CDB rotation since it was implemented.

METHODS: A survey was administered to 165 residents who completed the CDB rotation.

RESULTS: Of 165 residents, 136 (82%) responded to the survey. Of 122 residents who reported the type of project they conducted, 59 (48%) completed a clinical/health services project, 24 (20%) completed a project in education or curriculum development, and 7 (6%) worked in basic science. Thirty-five residents (27%) received funding to support their work. Thirty-five residents (26%) presented at national meetings such as the Pediatric Academic Societies Meeting. Fifteen (11%) residents have had manuscripts accepted for publication, and 22 (16%) additional residents have submitted manuscripts for publication. Factors associated with successful publication included having received funding (odds ratio: 3.37 [95% confidence interval: 1.34–8.42]) and the nature of the research project (odds ratio: 3.55 [95% confidence interval: 1.40–9.04]). The majority of residents (84%) stated that the CDB rotation enhanced residency training.

CONCLUSIONS: A dedicated academic rotation that includes protected time, senior faculty mentorship, and program funding, can lead to productive research accomplishments by pediatric residents. Support of academic work during residency training may encourage engagement in a variety of academically oriented activities.

OBJECTIVES: To develop an ED-based intervention including asthma symptom screening, a video addressing beliefs and a mailed reminder; and measure the effect on PCP follow-up and asthma-related outcomes.

METHODS: This randomized, controlled trial enrolled children aged 1 to 18 years who were discharged after asthma treatment in an urban pediatric ED. Control subjects received instructions to follow-up with a PCP within 3 to 5 days. In addition, intervention subjects (1) received a letter to take to their PCP if they screened positive for persistent asthma symptoms, (2) viewed a video featuring families and providers discussing the importance of asthma control, and (3) received a mailed reminder to follow-up with a PCP. All subjects were contacted by telephone 1, 3, and 6 months after the ED visit, and follow-up was confirmed by PCP record review. Asthma-related quality of life (AQoL), symptoms, and beliefs about asthma care were assessed by using validated surveys.

RESULTS: A total of 433 subjects were randomly assigned, and baseline measures were similar between study groups. After the intervention and before ED discharge, intervention subjects were more likely to endorse beliefs about the benefits of follow-up than controls. However, rates of PCP follow-up during the month after the ED visit (44.5%) were similar to control subjects (43.8%) as were AQoL, medication use, and ED visits.

CONCLUSIONS: An ED-based intervention influenced beliefs but did not increase PCP follow-up or asthma-related outcomes.

METHODS: From February to May 2008, 394 program directors from the Association of Pediatric Program Directors were surveyed.

RESULTS: Of 386 eligible survey respondents, 233 (60%) returned partial or complete surveys. Programs were evenly divided on whether ethics was taught as an organized curriculum or integrated. Professionalism was combined with the ethics curriculum in 27% of programs and taught independently in 38% of programs, but 35% had no professionalism curriculum. More than one third of the respondents did not answer each content and structure question. Approximately two thirds of those who responded stated that their program dedicated <10 hours per year to ethics and professionalism, respectively. Nearly three fourth of programs identified crowding of the curriculum and one third identified lack of faculty expertise as curricular constraints. Respondents expressed interest in more curricular materials from the American Board of Pediatrics or Association of Pediatric Program Directors.

CONCLUSIONS: Despite requirements to train and evaluate residents in ethics and professionalism, there is a lack of structured curriculum, faculty expertise, and evaluation methodology. Effectiveness of training curricula and evaluation tools need to be assessed if the Accreditation Council for Graduate Medical Education requirements for competencies in these areas are to be meaningfully realized.

METHODS: We used data from the 2004 Medical Expenditure Panel Survey linked to the National Health Interview Survey. Independent variables were grouped as predisposing characteristics, enabling factors, perceived need, and evaluated need. Multivariate logistic regression was used to assess the impact of independent variables on the outcomes of overall and specific types of medication use.

RESULTS: Hispanic, Spanish-interviewed children were less likely to have a usual source of care than were Hispanic, English-interviewed subjects. Both groups had lower odds of using any prescription medication, compared with white children, which was explained largely by having a usual source of care. The lower use of psychiatric medications in the Spanish-interviewed group was not explained by the independent variables, whereas the difference in the use of antibiotics was.

CONCLUSIONS: There are differences between Hispanic children according to acculturation, and acculturation affects prescription medication use. These findings may be used to address more specifically the needs of Hispanic children, particularly mental health needs.

OBJECTIVE: To systematically review the effectiveness of specific screening modalities to prevent neonatal bilirubin encephalopathy.

METHODS: We identified studies through Medline searches, perusing reference lists and by consulting with US Preventive Services Task Force lead experts. We included English-language publications evaluating the effects of screening for bilirubin encephalopathy using early total serum bilirubin (TSB), transcutaneous bilirubin (TcB) measurements, or risk scores. Severe hyperbilirubinemia was used as a surrogate for possible chronic bilirubin encephalopathy, because no studies directly evaluated the latter as an outcome. We calculated the sensitivity and specificity of early TSB, TcB measurements, or risk scores in detecting hyperbilirubinemia.

RESULTS: Ten publications (11 studies) were eligible. Seven (2 prospective) studies evaluated the ability of risk factors (n = 3), early TSB (n = 3), TcB (n = 2), or combinations of risk factors and early TSB (n = 1) to predict hyperbilirubinemia (typically TSB > 95th hour-specific percentile 24 hours to 30 days postpartum). Screening had good ability to detect hyperbilirubinemia: reported area-under-the-curve values ranged between 0.69 and 0.84, and reported sensitivities and specificities suggested similar diagnostic ability. Indirect evidence from 3 descriptive uncontrolled studies suggests favorable associations between initiation of screening and decrease in hyperbilirubinemia rates, and rates of treatment or readmissions for hyperbilirubinemia compared with the baseline of no screening. No study assessed harms of screening.

CONCLUSIONS: Effects of screening on the rates of bilirubin encephalopathy are unknown. Although screening can predict hyperbilirubinemia, there is no robust evidence to suggest that screening is associated with favorable clinical outcomes.

METHODS: The USPSTF reviewed experimental and observational studies that included comparison groups. For harms associated with phototherapy, case reports or case series were also included.

CONCLUSION: The evidence is insufficient to assess the balance of benefits and harms of screening for hyperbilirubinemia to prevent chronic bilirubin encephalopathy (I statement).

RESULTS: The accuracy of BMI varies according to the degree of body fatness. Among relatively fat children, BMI is a good indicator of excess adiposity, but differences in the BMIs of relatively thin children can be largely due to fat-free mass. Although the accuracy of BMI in identifying children with excess body fatness depends on the chosen cut points, we have found that a high BMI-for-age has a moderately high (70%–80%) sensitivity and positive predictive value, along with a high specificity (95%). Children with a high BMI are much more likely to have adverse risk factor levels and to become obese adults than are thinner children. Skinfold thicknesses and the waist circumference may be useful in identifying children with moderately elevated levels of BMI (85th to 94th percentiles) who truly have excess body fatness or adverse risk factor levels.

CONCLUSION: A BMI for age at ≥95th percentile of the CDC reference population is a moderately sensitive and a specific indicator of excess adiposity among children.

METHODS: An extensive search for scientific articles, position statements, and current state legislation related to BMI-measurement programs was conducted. A literature and policy review was written and presented to a panel of experts. This panel, comprising experts in public health, education, school counseling, school medical care, and parenting, reviewed and provided expertise on this article.

RESULTS: School-based BMI-measurement programs are conducted for surveillance or screening purposes. Thirteen states are implementing school-based BMI-measurement programs as required by legislation. Few studies exist that assess the utility of these programs in preventing increases in obesity or the effects these programs may have on weight-related knowledge, attitudes, and behaviors of youth and their families. Typically, expert organizations support school-based BMI surveillance; however, controversy exists over screening. BMI screening does not currently meet all of the American Academy of Pediatrics’ criteria for determining whether screening for specific health conditions should be implemented in schools.

CONCLUSION: Schools initiating BMI-measurement programs should adhere to safeguards to minimize potential harms and maximize benefits, establish a safe and supportive environment for students of all body sizes, and implement science-based strategies to promote physical activity and healthy eating.

METHODS: With a nationally representative sample of children aged 1 to 21 years in the National Health and Nutrition Examination Survey 2001–2004 (n = 6275), we measured serum 25(OH)D deficiency and insufficiency (25[OH]D <15 ng/mL and 15–29 ng/mL, respectively) and cardiovascular risk factors.

RESULTS: Overall, 9% of the pediatric population, representing 7.6 million US children and adolescents, were 25(OH)D deficient and 61%, representing 50.8 million US children and adolescents, were 25(OH)D insufficient. Only 4% had taken 400 IU of vitamin D per day for the past 30 days. After multivariable adjustment, those who were older (odds ratio [OR]: 1.16 [95% confidence interval (CI): 1.12 to 1.20] per year of age), girls (OR: 1.9 [1.6 to 2.4]), non-Hispanic black (OR: 21.9 [13.4 to 35.7]) or Mexican-American (OR: 3.5 [1.9 to 6.4]) compared with non-Hispanic white, obese (OR: 1.9 [1.5 to 2.5]), and those who drank milk less than once a week (OR: 2.9 [2.1 to 3.9]) or used >4 hours of television, video, or computers per day (OR: 1.6 [1.1 to 2.3]) were more likely to be 25(OH)D deficient. Those who used vitamin D supplementation were less likely (OR: 0.4 [0.2 to 0.8]) to be 25(OH)D deficient. Also, after multivariable adjustment, 25(OH)D deficiency was associated with elevated parathyroid hormone levels (OR: 3.6; [1.8 to 7.1]), higher systolic blood pressure (OR: 2.24 mmHg [0.98 to 3.50 mmHg]), and lower serum calcium (OR: –0.10 mg/dL [–0.15 to –0.04 mg/dL]) and high-density lipoprotein cholesterol (OR: –3.03 mg/dL [–5.02 to –1.04]) levels compared with those with 25(OH)D levels ≥30 ng/mL.

CONCLUSIONS: 25(OH)D deficiency is common in the general US pediatric population and is associated with adverse cardiovascular risks.

METHODS: We conducted a cross-sectional analysis of 3577 fasting, nonpregnant adolescents without diagnosed diabetes who participated in the 2001–2004 National Health and Nutrition Examination Survey. Cardiovascular risk factors were measured using standard methods and defined according to age-modified Adult Treatment Panel III definitions.

RESULTS: Mean 25(OH)D was 24.8 ng/mL; it was lowest in black (15.5 ng/mL), intermediate in Mexican American (21.5 ng/mL), and highest in white (28.0 ng/mL) adolescents (P < .001 for each pairwise comparison). Low 25(OH)D levels were strongly associated with overweight status and abdominal obesity (P for trend < .001 for both). After adjustment for age, gender, race/ethnicity, BMI, socioeconomic status, and physical activity, 25(OH)D levels were inversely associated with systolic blood pressure (P = .02) and plasma glucose concentrations (P = .01). The adjusted odds ratio (95% confidence interval) for those in the lowest (<15 ng/mL) compared with the highest quartile (>26 ng/mL) of 25(OH)D for hypertension was 2.36 (1.33–4.19); for fasting hyperglycemia it was 2.54 (1.01–6.40); for low high-density lipoprotein cholesterol it was 1.54 (0.99–2.39); for hypertriglyceridemia it was 1.00 (0.49–2.04); and for metabolic syndrome it was 3.88 (1.57–9.58).

CONCLUSIONS: Low serum vitamin D in US adolescents is strongly associated with hypertension, hyperglycemia, and metabolic syndrome, independent of adiposity.

PARTICIPANTS AND METHODS: Participants were 10 620 men and women from the 1958 British Birth Cohort Study whose IQ was assessed at the age of 11 years and who were followed up to age 46. Childhood covariates included birth weight, childhood height at 11 years of age, problem behaviors, father's occupational class, parents' interest in child's education, family size, and family difficulties. Adult risk factors were assessed at ages 23, 33, and 42 years, and they included education, occupational class, marital status, smoking, BMI, alcohol use, and psychosomatic symptoms.

RESULTS: Between ages 23 and 46 years, 192 participants died. Higher childhood IQ was related to lower mortality risk (standardized odds ratio [OR]: 0.80 [95% confidence interval (CI): 0.69–0.93]) with no gender differences (OR: 0.81 [95% CI: 0.67–0.98] [men] and 0.79 [95% CI: 0.63–0.98] [women]). Adjusting for parents' interest in child's education attenuated the IQ-mortality association by 15% to 20%, and adult education and psychosomatic symptoms both attenuated the association by 25%. Other covariates were less influential.

CONCLUSIONS: In a cohort of British men and women, the most important explanatory factors for the lower mortality rate among individuals with high IQ were parental interest in child's education, high adult educational level, and low prevalence of psychosomatic symptoms. However, common sociodemographic risk factors and health behaviors may not be sufficient to explain the association between IQ and early mortality completely.

SUBJECTS AND MATERIALS: Two phase-3, multicenter, randomized, evaluator/investigator-blinded studies compared 0.9% spinosad without nit-combing to 1% permethrin with combing (according to product instructions) in 1038 males and females aged ≥6 months. Spinosad-with-combing groups were included for descriptive, noninferential purposes only. Within 391 households, youngest members having ≥3 live lice were designated primary participants. All household members with lice received the same treatment. Participants administered product 1 to 2 times during the 21-day home-use period on the basis of complete lice eradication after a single use or the presence of lice requiring a second treatment. Scalp evaluations were performed at baseline, day 7, and day 14 (and day 21 for participants treated twice). The primary end point was the proportion of lice-free primary participants 14 days after last treatment.

RESULTS: A total of 84.6% (study 1) and 86.7% (study 2) of spinosad-treated participants were lice free versus 44.9% and 42.9% permethrin-treated participants (P < .001). Most spinosad-treated participants required 1 application, whereas most permethrin-treated participants required 2 applications. Few adverse events were reported, but those occurring were mild to moderate, including eye irritation (permethrin), ocular hyperemia, and application-site erythema/irritation (both medications). No laboratory measure changed significantly.

CONCLUSIONS: Spinosad, which did not require nit combing, was significantly more effective than permethrin in 2 studies reflecting actual-use conditions, and most spinosad-treated participants required only 1 application. Spinosad is a more convenient and effective treatment for pediculosis capitis.

METHODS: A consecutive series of 200 newborns was recruited on the second day of life. Each subject was studied while placed in the hospital crib (30 minutes), car bed (60 minutes), and car seat (60 minutes). Physiologic data, including oxygen saturation, frequency, and type of apnea, hypopnea, and bradycardia were obtained and analyzed in a blinded manner.

RESULTS: The mean oxygen saturation level was significantly different among all of the positions (97.9% for the hospital crib, 96.3% for the car bed, and 95.7% for the car seat; P < .001). The mean minimal oxygen saturation level was lower while in both safety devices (83.7% for the car bed and 83.6% for the car seat) compared with in the hospital crib (87.4%) (P < .001). The mean total time spent with an oxygen saturation level of <95% was significantly higher (P = .003) in both safety devices (car seat: 23.9%; car bed: 17.2%) when compared with the hospital crib (6.5%). A second study of 50 subjects in which each infant was placed in each position for 120 minutes yielded similar results.

CONCLUSIONS: In healthy term newborns, significant desaturations were observed in both car beds and car seats as compared with hospital cribs. This study was limited by lack of documentation of sleep stage. Therefore, these safety devices should only be used for protection during travel and not as replacements for cribs.

METHODS: Charts of all girls 5 to 17 of age who provided a history of nonacute, penile-genital, penetrative abuse were reviewed. Interviews and examinations occurred over a 4-year period at a children's advocacy center. Characteristics of the histories provided by the subjects were examined for associations with definitive findings of penetrative trauma.

RESULTS: Five hundred six patients were included in the study. Of the 56 children with definitive examination results, 52 had no history of consensual penile-vaginal intercourse and all were ≥10 years of age. Analysis was unable to detect an association between the number of reported penile-genital penetrative events and definitive genital findings. Eighty-seven percent of victims who provided a history of >10 penetrative events had no definitive evidence of penetration. A history of bleeding with abuse was more than twice as likely for subjects with definitive findings. Children <10 years of age were twice as likely to report >10 penetrative events, although none had definitive findings on examination.

CONCLUSIONS: Most victims who reported repetitive penile-genital contact that involved some degree of perceived penetration had no definitive evidence of penetration on examination of the hymen. Similar results were seen for victims of repetitive assaults involving perceived penetration over long periods of time, as well as victims with a history of consensual sex.

METHODS: A retrospective review of data for all patients seen between January 1990 and April 2007 was performed. Patients were stratified into 5 groups on the basis of age at diagnosis.

RESULTS: A total of 1374 patients were identified; 61 (4%) were <6 months of age at diagnosis, 114 (8%) 6 months to <1 year, 854 (62%) 1 to 4 years, 258 (19%) 5 to 9 years, and 87 (6%) >9 years. Patients <1 year of age and those >9 years of age were more likely to have coronary artery abnormalities than were patients diagnosed between 1 and 4 years of age. Patients diagnosed between the ages of 5 and 9 years were at the lowest risk. Patients at both extremes of the age spectrum were more likely to present with <4 of the classic KD features, but only those <6 months or >5 years of age were at increased risk of being diagnosed >12 days after illness onset. Patients <6 months of age had lower albumin levels, and those <1 year of age had higher white blood cell and platelet counts, all of which are known predictors of coronary artery abnormalities. Patients >9 years of age were less likely to receive intravenous immunoglobulin treatment.

CONCLUSION: Outcomes for children diagnosed with KD at either extreme of the age spectrum are suboptimal, although the associated factors are different.

METHODS: Magazines were included in this study if they had an average female readership of >5 million, circulation of >900000, and median age of female readers of 20 to 40 years. Twenty magazines met these criteria. An additional 8 magazines targeted toward expectant parents and parents of young children were included, for a total of 28 magazines. Pictures of infant sleep environments and sleeping infants in articles and advertisements in issues of these 28 magazines were analyzed for adherence to AAP guidelines for decreasing the risk of sudden infant death syndrome.

RESULTS: A total of 391 unique pictures from 34 magazine issues were included in the analysis. Only 57 pictures (64%) portraying sleeping infants not being held by an adult portrayed the infants in the supine position, and 14.8% of sleeping infants were portrayed as sleeping with another person. Only 36 pictures (36.4%) of infant sleep environments portrayed a safe sleep environment, as recommended by the AAP.

CONCLUSIONS: More than one third of pictures of sleeping infants in magazines geared toward childbearing women demonstrated infants in an inappropriate sleep position, and two thirds of pictures of infant sleep environments were not consistent with AAP recommendations. Messages in the media that are inconsistent with health care messages create confusion and misinformation about infant sleep safety and may lead inadvertently to unsafe practices.

METHODS: Propranolol was given to 32 children (21 girls; mean age at onset of treatment: 4.2 months) after clinical and ultrasound evaluations. After electrocardiographic and echocardiographic evaluations, propranolol was administered with a starting dose of 2 to 3 mg/kg per day, given in 2 or 3 divided doses. Blood pressure and heart rate were monitored during the first 6 hours of treatment. In the absence of side effects, treatment was continued at home and the child was reevaluated after 10 days of treatment and then every month. Ultrasound measurements were performed after 60 days of treatment.

RESULTS: Immediate effects on color and growth were noted in all cases and were especially dramatic in cases of dyspnea, hemodynamic compromise, or palpebral occlusion. In ulcerated IHs, complete healing occurred in <2 months. Objective clinical and ultrasound evidence of longer-term regression was seen in 2 months. Systemic corticosteroid treatment could be stopped within a few weeks. Treatment was administered for a mean total duration of 6.1 months. Relapses were mild and responded to retreatment. Side effects were limited and mild. One patient discontinued treatment because of wheezing.

CONCLUSION: Propranolol administered orally at 2 to 3 mg/kg per day has a consistent, rapid, therapeutic effect, leading to considerable shortening of the natural course of IHs, with good clinical tolerance.

METHODS: We conducted a nationally representative, Internet-based survey of parents. Parents received 2 vignettes describing hypothetical diseases without treatments. The first vignette described a disease in which symptoms were severe and timing of symptom onset was uncertain. The second vignette described a disease in which both symptom severity and timing of symptom onset were uncertain. Parents reported their interest in predictive genetic testing for their youngest child in each vignette by using a 5-point Likert scale. We collected information on parents' demographic features and parents' general opinions about genetic testing. We conducted logistic regression analyses to evaluate the independent associations between these factors and parents' interest in testing for both vignettes.

RESULTS: The response rate was 71%. For the first vignette, 35% of parents were definitely or probably interested in predictive genetic testing for their youngest child, 35% were unsure, and 31% were definitely or probably not interested. Responses were similar for the second vignette. More than one fourth of parents consistently expressed interest in testing in both vignettes.

CONCLUSIONS: Approximately one third of parents are interested in predictive genetic testing for their children, even for disorders with no treatment. Uncertainty about the severity of symptoms was not related to parents' testing preferences.

METHODS: Randomized assignment to receive 30% (N = 37) or 90% (N = 41) oxygen was performed. Targeted oxygen saturation values were 75% at 5 minutes and 85% at 10 minutes. Blood oxidized glutathione (GSSG)/reduced glutathione ratio and urinary o-tyrosine, 8-oxo-dihydroxyguanosine, and isoprostane levels, isofuran elimination, and plasma interleukin 8 and tumor necrosis factor levels were determined.

RESULTS: The low-oxygen group needed fewer days of oxygen supplementation (6 vs 22 days; P < .01) and fewer days of mechanical ventilation (13 vs 27 days; P < .01) and had a lower incidence of bronchopulmonary dysplasia at discharge (15.4% vs 31.7%; P < .05). GSSG/reduced glutathione x 100 ratios at day 1 and 3 were significantly higher in the high-oxygen group (day 1: high-oxygen group: 13.36 ± 5.25; low-oxygen group: 8.46 ± 3.87; P < .01; day 3: high-oxygen group: 8.87 ± 4.40; low-oxygen group: 6.97 ± 3.11; P < .05). Urinary markers of oxidative stress were increased significantly in the high-oxygen group, compared with the low-oxygen group, in the first week after birth. GSSG levels on day 3 and urinary isofuran, o-tyrosine, and 8-hydroxy-2'-deoxyguanosine levels on day 7 were correlated significantly with development of chronic lung disease.

CONCLUSIONS: Resuscitation of preterm neonates with 30% oxygen causes less oxidative stress, inflammation, need for oxygen, and risk of bronchopulmonary dysplasia.

METHODS: We collected data about prenatal, placental, and neonatal characteristics of 1241 newborns who were delivered before completion of the 28th week of gestation. Associations between prenatal factors, microbiologic and histologic characteristics of the placenta, and selected neonatal characteristics and CLD risk were first evaluated in univariate analyses. Subsequent multivariate analyses investigated the contribution of prenatal factors, particularly fetal growth restriction (FGR), to CLD risk.

RESULTS: Among the prenatal factors, birth weight z scores, used as a marker of FGR, provided the most information about CLD risk. Indicators of placental inflammation and infection were not associated with increased risk of CLD. Within nearly all strata of prenatal, placental, and neonatal variables, growth-restricted infants were at increased CLD risk, compared with infants who were not growth-restricted. FGR was the only maternal or prenatal characteristic that was highly predictive of CLD after adjustment for other risk factors.

CONCLUSIONS: FGR is independently associated with the risk of CLD. Thus, factors that control fetal somatic growth may have a significant impact on vulnerability to lung injury and in this way increase CLD risk.

METHODS: Continuous, multichannel, video-EEG was recorded for term infants with hypoxic-ischemic encephalopathy, from <6 hours to 72 hours after delivery. One-hour segments at 6, 12, 24, and 48 hours of age of the EEG were analyzed visually, and neurologic outcome was assessed at 24 months.

RESULTS: Forty-four infants completed neurodevelopmental follow-up. Of those, 20 (45%) had abnormal outcomes. The EEG grade assigned correlated significantly with outcome. EEG abnormalities improved with time, with the worst EEG grade seen on the earliest recording in all cases. The best predictive ability was seen at 6 hours of age (area under the receiver operator characteristic curve: 0.958 [95% confidence interval: 0.88–1.04]; P = .000). Normal/mildly abnormal EEG results at 6, 12, or 24 hours had 100% positive predictive values for normal outcomes and negative predictive values of 67% to 76%. By 48 hours, many of the EEG findings had improved significantly. This led to the positive predictive value of abnormal EEG results being greater at 48 hours (93%), with a concurrent negative predictive value of 71%. EEG features that were associated with abnormal outcomes were background amplitude of <30 µV, interburst interval of >30 seconds, electrographic seizures, and absence of sleep-wake cycling at 48 hours.

CONCLUSIONS: Early EEG is a reliable predictor of outcome in HIE. A normal or mildly abnormal EEG results within 6 hours after birth were associated with normal neurodevelopmental outcomes at 24 months.

METHODS: We obtained serial EEG findings for all premature infants who were admitted to our hospital at gestational age of ≤33 weeks between 1997 and 2006. EEG recordings were obtained on days 1 to 4, 5 to 14, 15 to 28, 29 to 56, and 57 to 84. Abnormal EEG findings were classified as acute-stage abnormalities (ASAs) or chronic-stage abnormalities (CSAs) and were subclassified as mild, moderate, or severe. PVL was classified as noncystic, localized cystic, or extensive cystic. The final diagnosis of PVL was made through neurologic assessment and MRI findings at 24 months.

RESULTS: Fifty-five infants were diagnosed as having PVL, including 23 with noncystic PVL, 9 with localized cystic PVL, and 23 with extensive cystic PVL. ASAs were observed most frequently on days 1 to 4 and were observed rarely thereafter in all groups. CSAs were observed most frequently on days 5 to 14, were most severe on days 5 to 14, and then resolved within 1 to 2 months in all groups. CSAs in patients with extensive cystic PVL were more severe and persisted longer, compared with other groups. ASA and CSA severity was correlated with PVL severity.

CONCLUSIONS: EEG findings in PVL differed according to the severity of PVL and the time of recording. To detect PVL, ≥2 EEG recordings are recommended, 1 within 48 hours after birth, to detect ASAs, and 1 in the second week of life, to detect CSAs.

METHODS: Patients followed at the NF1 clinic at the Hospital for Sick Children, Toronto, Ontario, Canada, between 1990 and 2007 were studied. Patients with confirmed NF1 diagnosis and neuroimaging results were included. All neuroimaging studies were reviewed for the presence of arteriopathy by 2 study pediatric neuroradiologists blinded to clinical information. Clinical records of children with cerebral arteriopathy were reviewed.

RESULTS: Among 419 children with confirmed NF1, 266 (63%) received neuroimaging. Among children with neuroimaging results, 17 had cerebral arteriopathy (minimum prevalence rate of 6%). Among the 35 patients who received magnetic resonance angiography (MRA), arteriopathy was more common in patients with NF1 with optic gliomas (11 of 21) compared with those without optic glioma (4 of 14). Forty-seven percent of children developed focal deficits months to years after the diagnosis of the arteriopathy. Follow-up at a mean of 7 years after diagnosis of arteriopathy showed that 35% (6 of 17) had progressive arteriopathy requiring revascularization surgery. Seven patients received aspirin for primary stroke prevention. On retrospective review of imaging studies, a mean delay of 51 months to clinical radiographic reporting of these findings was observed.

CONCLUSIONS: The prevalence of cerebral arteriopathy in children with NF1 in this study was at least 6% and was associated with young age and optic glioma. Arteriopathy causes stroke with resultant neurologic deficits. Medical and/or surgical interventions may prevent these complications. Therefore, the addition of vascular imaging (MRA/conventional angiography) to brain imaging studies for early detection of arteriopathy should be considered for children with NF1, particularly young patients with optic glioma.

METHODS: We used stored historic IVIg samples and current samples from our inpatient pharmacy. All samples were tested for varicella-specific IgG levels by enzyme-linked immunosorbent assay.

RESULTS: Ten historic lots and 24 current lots were tested. The overall mean value of varicella-specific IgG in the historic lots was 3.07 (SD: 0.70); the current lots had a mean of 3.83 (SD: 0.58). The postvaccine IVIg contained higher levels of antibody than the prevaccine lots.

CONCLUSIONS: We found that current IVIg preparations continue to have high levels of varicella-specific IgG despite the changing epidemiology of how immunity has been obtained. Given the results of this study, it is reasonable for physicians to comfortably substitute IVIg for varicella-specific immunoglobulin preparations when treating high-risk patients exposed to VZV.

OBJECTIVES: The objectives of this study were to (1) compare and audit our practice with the published standards for screening for CD in children with DM, (2) characterize the children with DM and biopsy-confirmed CD, in terms of growth and gastrointestinal symptoms, and compare them with children with DM and negative celiac serology, and (3) document the effects of a gluten-free diet (GFD) after 1 year of gastrointestinal symptoms, growth, and insulin requirement.

METHOD: We performed a retrospective case-note review of 22 children with DM, positive celiac serology ± biopsy-confirmed CD, and 50 children with DM and negative celiac serology.

RESULTS: Twenty-two children (3.9% of the total diabetic population) had positive celiac serology on screening, with 17 (3%) having biopsy-confirmed CD. Ninety-four percent of the children had standardized celiac serology testing. At diagnosis of CD, 13 of the 17 biopsy-positive children (76.4%) had ≥1 gastrointestinal symptom. The frequency of gastrointestinal symptoms in negative celiac serology diabetic children was 6% (3 of 50) (P < .0005). Symptoms resolved in all children after introduction of a GFD. A significant improvement in weight SD score (P = .008) and BMI SD score (P = .02) was noted in those compliant with a GFD after 1 year.

CONCLUSIONS: Children with DM and CD have a higher frequency of gastrointestinal symptoms than their diabetic peers with negative celiac serology and are not truly asymptomatic. Institution of a GFD has a positive effect on nutritional status and symptom resolution in the short-term.

METHODS: A retrospective chart review of 101 subjects with PCOS and 40 without PCOS was conducted. Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), Quantitative Insulin Sensitivity Check Index (QUICKI), and fasting glucose/insulin ratio (FGIR) values were calculated by using fasting glucose and insulin levels. Insulin resistance (IR) was defined as a fasting insulin level of >15 µU/mL, a 2-hour insulin level of >75 µU/mL, a HOMA-IR value of >3.16, a QUICKI value of <0.357, and/or a FGIR value of <7.

RESULTS: Of the 101 overweight subjects with PCOS (BMI: 33.2 ± 5.9 kg/m²), 4 had IGT and 2 had DM versus none of the 40 subjects without PCOS (BMI: 32.4 ± 5.3 kg/m²). IR was more frequent in the overweight PCOS than in the overweight non-PCOS group (QUICKI: 68.4% vs 14.3%, P = .014) and FGIR (47.4% vs 0%, P = .024). Of the 6 subjects with glucose intolerance, only the QUICKI value was abnormal in all.

CONCLUSIONS: This retrospective study demonstrated that overweight Hispanic adolescents with PCOS had more IR, IGT and DM than their non-PCOS counterparts. As the QUICKI Index was abnormal in all subjects with IGT and DM, we suggest its use as the first step in deciding which overweight Hispanic adolescents with PCOS should be further tested with an OGTT.

METHODS: Parents of children with food allergies were offered investigational oral immunotherapy (OIT) in a regular outpatient clinic. Forty parents (group A) declined, and 25 parents (group B) agreed to take part. Both groups agreed to complete the Food Allergy Quality of Life–Parent Form and the Food Allergy Independent Measure.

RESULTS: Children were aged between 1 and 12 years (mean: 6.5 years). Groups A and B displayed a similar and typical distribution for gender, age, number of foods, severity and number of symptoms, and socioeconomic variables. Parents who chose to enroll their children in the OIT trial reported a similar impact of food allergy on the HRQoL of their children as parents of children who did not volunteer for the study. Participating parents perceived a significantly higher likelihood (odds ratio: 6.753) of their child having a severe reaction and dying if food is ingested. By using this model, the likelihood of taking part in immunotherapy could be predicted accurately in 90% of cases.

CONCLUSIONS: Parents who had higher anxiety about negative outcomes from accidental ingestion were more likely to consent to experimental therapy for their child. This finding has ethical implications for investigators and supports the need to create mechanisms to avoid unintended coercion in vulnerable groups.

METHODS: Since 2002, we have considered prenatal intervention for fetal PA/IVS in patients with (1) membranous pulmonary atresia, with identifiable pulmonary valve (PV) leaflets or membrane; (2) an intact or highly restrictive ventricular septum; and (3) right heart hypoplasia, with a tricuspid valve annulus z score of –2 or below and an identifiable but small right ventricle. Intervention was performed through direct cardiac puncture under ultrasound guidance, with percutaneous access or access through a limited laparotomy.

RESULTS: Ten fetuses underwent attempted balloon dilation of the PV in utero. The first 4 procedures were technically unsuccessful, and the most-recent 6 were technically successful. Compared with control fetuses with PA/IVS who did not undergo prenatal intervention and had univentricular outcomes after birth, the tricuspid valve annulus, right ventricle length, and PV annulus grew significantly more from midgestation to late gestation in the 6 fetuses who underwent successful interventions.

CONCLUSIONS: In utero perforation and dilation of the PV in midgestation fetuses with PA/IVS is technically feasible and may be associated with improved right heart growth and postnatal outcomes for fetuses with moderate right heart hypoplasia in midgestation. There is an important learning curve for this procedure, and much remains to be learned about the selection of appropriate fetuses for prenatal intervention.

OBJECTIVE: To determine the impact of GH therapy on adult height in short SGA children by a meta-analysis of randomized, controlled trials (RCTs).

METHODS: We performed a systematic review of controlled studies using as data sources the Cochrane Central Register of Controlled Trials, Medline, and the bibliographic references from all retrieved articles describing RCTs up to November 2008. A meta-analysis of all RCT studies conducted up to the achievement of adult height was performed. Inclusion criteria were birth weight and/or length below –2 SD score (SDS), initial height less than –2 SDS, and GH dose range of 33 to 67 µg/kg per day. Adult height SDS and overall height gain SDS were the primary outcome measures.

RESULTS: Four RCTs (391 children) met the inclusion criteria. The adult height of the GH-treated group significantly exceeded controls by 0.9 SDS. Mean height gain was 1.5 SDS in treated versus 0.25 SDS in untreated SGA subjects. No significant difference in adult height was observed between the 2 GH dose regimens.

CONCLUSIONS: GH therapy seems to be an effective approach to partially reduce the adult height deficit in short SGA children. However, the response to therapy is highly variable, and additional studies are needed to identify the responders.

METHODS: A systematic review of electronic databases (PubMed, Ovid, Web of Science, Cochrane Reviews Database, Google Scholar) was conducted from 1982 to 2008, obtaining a sample of 16 empirical studies related to sitting-meditation interventions among youth.

RESULTS: Meditation modalities included mindfulness meditation, transcendental meditation, mindfulness-based stress reduction, and mindfulness-based cognitive therapy. Study samples primarily consisted of youth with preexisting conditions such as high-normal blood pressure, attention-deficit/hyperactivity disorder, and learning disabilities. Studies that examined physiologic outcomes were composed almost entirely of African American/black participants. Median effect sizes were slightly smaller than those obtained from adult samples and ranged from 0.16 to 0.29 for physiologic outcomes and 0.27 to 0.70 for psychosocial/behavioral outcomes.

CONCLUSIONS: Sitting meditation seems to be an effective intervention in the treatment of physiologic, psychosocial, and behavioral conditions among youth. Because of current limitations, carefully constructed research is needed to advance our understanding of sitting meditation and its future use as an effective treatment modality among younger populations.

METHODS: Thirty-one focus groups (282 pediatricians and 41 pediatric nurse practitioners) in 13 cities addressed current practices, priorities used to determine content of well-child care visits, and changes to improve visit quality and outcomes.

RESULTS: Although most clinicians were positive about their practice of well-child care, they reported areas of concern and suggested ideas for improvements. Establishing a therapeutic relationship and individualizing care were viewed as significant contributions to quality of care. Participants agreed about the importance of eliciting parent concerns as the first priority for all well-child care visits. Community resources outside the office setting were seen as both a major influence on and, in some communities, a limitation to pediatric care. The challenges of early recognition of developmental and behavior problems through standardized questionnaires and effective interviewing were viewed as a priority to improve pediatric effectiveness in monitoring and treatment. To enhance primary care practices in developmental and behavioral pediatrics, participants suggested innovations in practice organization, community linkages, information technology, and integration of existing innovative programs. Education for pediatricians and enhanced resident training in developmental and behavioral pediatrics were endorsed.

CONCLUSIONS: Pediatric clinicians' support a vision of preventive care that is comprehensive, family centered, and developmentally relevant, both for children with greater risk to long-term healthy development and for families with more normative child-rearing concerns.

METHODS: Twenty focus groups with parents (n = 131 [91% mothers]) were conducted by using a semistructured interview guide. Verbatim transcripts were coded for key words, concepts, and recurrent themes.

RESULTS: Primary reasons for visit attendance included reassurance (child and parent) and an opportunity to discuss parent priorities. Families valued an ongoing relationship with 1 clinician who was child-focused and respected parental expertise, but continuity of provider was not an option for all participants. Suggestions for enhancement included improved promotion of well-child care, greater emphasis on development and behavior, and expanded options for information exchange.

CONCLUSIONS: As the consumers of care, it is critical to understand parents' needs and desires as changes to the content and process of well-child care are considered. Taking into account the multifaceted perspectives of families suggests both challenges and opportunities for the rethinking discussion.

METHODS: This was a prospective regional study including all live-born infants ≤30 weeks' gestation born between July 1985 and June 1986 (cohort 1) and July 2005 and June 2006 (cohort 2). Sociodemographically matched term controls were recruited for each cohort. Perinatal characteristics, mortality rates, and survival with and without impairments at 24 months' corrected age were compared.

RESULTS: There was a 35% increase in the number of live-born preterm births (138 in cohort 1 and 187 in cohort 2) despite a >10% decline in total births in the region (P < .001). Assisted fertility (rarely available for mothers in cohort 1) was responsible for 20% of pregnancies in cohort 2. Survival to hospital discharge increased over 20 years from 82% to 93% (P = .002), primarily because of higher survival for infants born at <27 weeks' gestation (63% vs 88%; P = .004). Changes in management in cohort 2 included the use of surfactant (62% of infants) and increased use of postnatal steroids (39% vs 9%; P < .001), that were associated with a shorter median duration of mechanical ventilation (13 vs 21 days; P < .001); however, the incidence of bronchopulmonary dysplasia was higher in cohort 2 (56% vs 35%; P < .001). There was a significant decrease in incidence of severe ultrasound abnormalities from 17% in cohort 1 to 7% in cohort 2 (P = .008). At 24 months of age, 7% of cohort 1 and 5% of cohort 2 had an abnormal neurologic exam. Bayley cognitive scores were improved in cohort 2 (significantly closer to the mean of their controls). As a result, survival without severe neurodevelopmental impairment increased from 62% in cohort 1 to 81% in cohort 2 (P < .001).

CONCLUSION: Over 20 years, there has been a significant increase in live births at ≤30 weeks' gestational age, with a greater percentage of these neonates surviving without severe neurodevelopmental impairment at 24 months.

METHODS: We queried the American Association of Poison Control Center's National Poison Data System for the years of 1998–2005 for all cases involving people aged 13 to 19 years, for which the reason was intentional abuse or intentional misuse and the substance was a prescription medication used for ADHD treatment. For trend comparison, we sought data on the total number of exposures. In addition, we used teen and preteen ADHD medication sales data from IMS Health's National Disease and Therapeutic Index database to compare poison center call trends with likely availability.

RESULTS: Calls related to teenaged victims of prescription ADHD medication abuse rose 76%, which is faster than calls for victims of substance abuse generally and teen substance abuse. The annual rate of total and teen exposures was unchanged. Over the 8 years, estimated prescriptions for teenagers and preteenagers increased 133% for amphetamine products, 52% for methylphenidate products, and 80% for both together. Reports of exposure to methylphenidate fell from 78% to 30%, whereas methylphenidate as a percentage of ADHD prescriptions decreased from 66% to 56%. Substance-related abuse calls per million adolescent prescriptions rose 140%.

CONCLUSIONS: The sharp increase, out of proportion to other poison center calls, suggests a rising problem with teen ADHD stimulant medication abuse. Case severity increased over time. Sales data of ADHD medications suggest that the use and call-volume increase reflects availability, but the increase disproportionately involves amphetamines.

METHODS: Term neonates with a first symptomatic, community-acquired UTI participated in the study. Urinary tract ultrasonography and technetium-99m-labeled dimercaptosuccinic acid (^99mTc-DMSA) scintigraphy were performed within 72 hours after diagnosis and voiding cystourethrography within 1 to 2 months. DMSA scintigraphy, to determine the development of PRD, was repeated 6 months after UTI.

RESULTS: Seventy-two neonates (144 renal units) were enrolled. Acute pyelonephritis was diagnosed through early DMSA scintigraphy in 19% of renal units, VUR in 22%, and grade ≥III VUR in 13%. The majority (71%) of renal units with grade ≥III VUR had normal early DMSA scintigraphic results. The sensitivity and specificity of abnormal early DMSA scintigraphic results to predict grade ≥III VUR were 29% (95% confidence interval: 11%–55%) and 82% (95% confidence interval: 74%–88%), respectively. PRD was found in 7% of renal units, all of which had abnormal early DMSA scintigraphic results. PRD was significantly more frequent among renal units with grade ≥III VUR than among nonrefluxing renal units (P < .05).

CONCLUSIONS: Normal early DMSA scintigraphic results for neonates with symptomatic UTIs were helpful in ruling out later development of PRD but were not predictive of the absence of dilating VUR. To rule out dilating VUR, voiding cystourethrography may be required.

METHODS: A retrospective study of all subjects <21 years of age who presented to the emergency department at Akron Children's Hospital and underwent UCT of the abdomen between January 2002 and December 2005 was performed. Demographic, clinical, diagnostic, treatment, and disposition data were abstracted by using a standardized form. Univariate and logistic regression analyses of factors associated with urolithiasis were performed.

RESULTS: A total of 339 eligible patients were identified, with 110 cases of urolithiasis detected with UCT for 95 individual patients. The mean age of the study patients was 14.4 years; 72 patients (66%) were female. In 17 cases (15%) of urolithiasis, initial urinalysis results were negative for blood. Fifty-seven stones (51.8%) were ureteral, 26 (23.6%) were renal, and 4 (3.6%) were in the bladder. Among children who did not have a stone identified through UCT, 23 cases (10%) of potentially significant, alternative diagnoses were identified. A history of urolithiasis, a history of nausea and vomiting, the presence of flank pain on examination, and >2 red blood cells per high-power field in urine microscopy were positively associated with urolithiasis. A history of fever or dysuria and costovertebral angle tenderness on physical examination were inversely associated with urolithiasis on UCT scans.

CONCLUSIONS: UCT plays an important role in the diagnostic evaluation of children with flank pain. Approximately 15% of children with urolithiasis do not have hematuria.

METHODS: The analysis sample of 270 adolescent smokers was taken from the Raising Healthy Children project. Data were taken from annual interviews in grades 7 and 12. Daily smoking was defined as having smoked ≥1 cigarette per day in the past 30 days at the time of each interview. Discrete-time survival analysis was used to assess associations with individual, family, peer, and school predictors.

RESULTS: A total of 58% (n = 156) of the analysis sample made the transition to daily smoking by grade 12. The likelihood of onset of daily smoking among those who had not yet demonstrated onset was smallest in grade 9 (probability: 0.12) and greatest in grade 12 (probability: 0.25). Youth depression, prosocial beliefs, and antisocial behavior had overall associations with risk of smoking escalation. In addition, parents' and peers' smoking, family management, academic grades, and school commitment had significant univariate associations with smoking progression. After adjustment for gender, low-income status, and other potential predictors, youths' antisocial behavior and parents' and peers' smoking predicted greater likelihood of escalation to daily smoking, whereas parental use of positive family management predicted lower likelihood of escalation.

CONCLUSIONS: This study supports preventing escalation in adolescent smoking by targeting parents' and peers' smoking and involvement in other forms of antisocial behavior and working with parents to improve their use of positive family management practices.

METHODS: The study included 712 boys and girls in the sixth grade, from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Main outcome measures included Achenbach Teacher's Report Form internalizing, externalizing, and total scores; Children's Depression Inventory scores (child report); Life Orientation Test-Revised scores (child report); Child Behavior with Peers questionnaire asocial with peers, excluded by peers, and peer victimization subscale scores (teacher report); peer social support and victimization scores (child report); and relationships with peers score (teacher report). In bivariate comparisons, these outcomes were compared for children of relatively short (height of <10th percentile) versus nonshort (height of ≥10th percentile) stature, and effect sizes were calculated. Multivariate linear regression models adjusted for maternal education, income/needs ratio, race, and gender.

RESULTS: Effect sizes ranged from 0.00 to 0.35. Short children reported marginally higher levels of self-perceived peer victimization, compared with their nonshort peers. There were no significant differences in the rest of the outcomes for children of short versus nonshort stature, in either unadjusted or adjusted models.

CONCLUSION: Although short children from a population-based sample reported marginally higher levels of self-perceived peer victimization, they did not differ from their nonshort peers in a range of social, emotional, and behavioral outcomes.

METHODS: As part of the Strong African American Families preventive intervention study, data were collected from 641 black families in rural Georgia, assigned randomly to the prevention or control condition. The prevention condition consisted of 7 consecutive meetings at community facilities, with separate parent and youth skill-building curricula and a family curriculum. Each meeting included separate, concurrent sessions for parents and youths, followed by a joint parent-youth session in which families practiced skills they learned in the separate sessions. Involvement in risk behaviors was assessed when the youths were 11 (pretest), 12 (posttest), and 14 (long-term follow-up) years of age. A genetic vulnerability factor, that is, a variable-nucleotide repeat polymorphism in the promoter region of the SLC6A4 gene (5HTT), was assessed 2 years after the long-term follow-up assessment.

RESULTS: Youths at genetic risk who were assigned to the control condition displayed greater increases in risk behaviors across the 29 months that separated the pretest and long-term follow-up assessments, compared with youths at genetic risk who were assigned to the Strong African American Families condition and youths without genetic risk who were assigned to either condition.

CONCLUSION: This is the first study to demonstrate that participation in an efficacious preventive intervention can ameliorate a genetic risk for increasing involvement in health-compromising risk behaviors across preadolescence.

METHODS: A retrospective analysis was conducted with data for children and adolescents (5–18 years of age) from the National Electronic Injury Surveillance Study of the US Consumer Product Safety Commission, from 1997 through 2007. Sample weights provided by the National Electronic Injury Surveillance System were used to calculate national estimates of PE-related injuries. Trend significance of the number of PE-related injuries over time was analyzed by using linear regression analysis.

RESULTS: An estimated 405305 children and adolescents were treated in emergency departments for PE-related injuries. The annual number of cases increased 150% during the study period (P = .001). Nearly 70% of PE-related injuries occurred during 6 activities, that is, running, basketball, football, volleyball, soccer, and gymnastics. Boys' injuries were more likely to involve the head, to be diagnosed as a laceration or fracture, to be attributable to contact with a person or structure, and to occur during group activities. Girls' injuries were more likely to involve the lower extremities, to be strains and sprains, to be acute noncontact injuries, and to occur during individual activities.

CONCLUSION: More research is needed to identify the cause of the increase in PE-related injuries, to examine the gender difference in PE-related injuries, and to determine appropriate injury prevention solutions and policies.

PATIENTS AND METHODS: We queried 535 participants diagnosed before 18 years of age from the Chicago Childhood Diabetes Registry. Demographic, social, and clinical data were used in logistic models of diabetes-related rehospitalization, as well as, among those rehospitalized, frequent (≥ once per 2 years' duration) versus infrequent rehospitalization rates.

RESULTS: Mean (range) duration was 5.1 years (0.1–19.2 years). The sample was 55% non-Hispanic black, 11% non-Hispanic white, 26% Hispanic, and 7% other/mixed race; 86% had presumed type 1 diabetes; and 47% were underinsured. Overall, 46% reported rehospitalization for diabetes. In multivariable logistic regression, ever being rehospitalized was significantly associated with diabetes duration (per year, odds ratio [OR]: 1.26; P < .01), female gender (OR: 1.67; P = .01), underinsurance (versus private insurance; OR: 1.79; P < .01), presumed phenotype (non–type 1 diabetes versus type 1; OR: 0.32; P < .01), and diagnosis at a community hospital (versus tertiary care facility; OR: 1.96; P < .01) and tended to be higher for those of nonwhite race (OR: 1.94; P = .07). Among those rehospitalized, multivariable associations with frequent rehospitalization were presumed phenotype (non–type 1 diabetes versus type 1; OR: 2.74; P = .04), head of household not working (versus employed; OR: 1.88; P = .02), and younger age at questionnaire (per year; OR: 0.94; P = .01).

CONCLUSIONS: Rehospitalization is common in young patients with diabetes, especially for those with limited resources, indicating the need for improved outpatient services. Comprehensive initial education and support available to young patients with diabetes diagnosed at tertiary care facilities and their families may have lasting protective effects.

METHODS: In a PICU of a major tertiary-care pediatric medical center, 5000 orders were reviewed, that is, 1250 orders from each of 4 periods: period 1, before CPOE implementation; period 2, 1 year after CPOE implementation; period 3, after CDSS implementation; and period 4, after a change in prescription authorization. Prescription errors were identified and classified into: potential adverse drug events (ADEs), medication prescription errors (MPEs), and rule violations (RVs).

RESULTS: We identified 273 errors (5.5%). The rate of potential ADEs decreased slightly between periods 1 and 2 (from 2.5% to 2.4%) and significantly in periods 3 and 4 (to 0.8% and 0.7%, respectively; P < .005). The rate of MPEs decreased slightly between periods 1 and 2 (from 5.5% to 5.3%), but new types of MPEs appeared. There was a significant decrease in period 3 (to 3.8%; P < .05) and a dramatically significant decrease in period 4 (to 0.7%; P < .0005). Only 3 RVs were found. Interrater agreement ( statistic) was 0.788 between evaluators.

CONCLUSIONS: CPOE implementation decreased prescription errors only to a small extent. However, the addition of a CDSS that limits doses by weight significantly reduced prescription error rates and, most importantly, potential ADEs. This finding emphasizes the major impact of weight-based calculation errors in pediatrics.

METHODS: The Longitudinal Studies of Child Abuse and Neglect was a multisite, longitudinal investigation. Participants ranged from at-risk to substantiated maltreatment. Maltreatment history was assessed through Child Protective Service records and youth self-report at age 12. Youth reported emotional distress by using the Trauma Symptom Checklist at the age of 12 years and sexual intercourse at ages 14 and 16. Logistic and multiple regressions, adjusting for gender, race, and site, were used to test whether maltreatment predicts sexual intercourse, the explanatory effects of emotional distress, and gender differences.

RESULTS: At ages 14 and 16, maltreatment rates were 79% and 81%, respectively, and sexual initiation rates were 21% and 51%. Maltreatment (all types) significantly predicted sexual intercourse. Maltreated youth reported significantly more emotional distress than non-maltreated youth; emotional distress mediated the relationship between maltreatment and intercourse by 14, but not 16. At 14, boys reported higher rates of sexual intercourse than girls and the association between physical abuse and sexual intercourse was not significant for boys.

CONCLUSIONS: Maltreatment (regardless of type) predicts sexual intercourse by 14 and 16. Emotional distress explains the relationship by 14. By 16, other factors likely contribute to intercourse. Maltreated children are at risk for early initiation of sexual intercourse and sexually active adolescents should be evaluated for possible maltreatment.

METHODS: A self-complete survey was sent to a cross-sectional, stratified, random sample of 5 provider groups in Ontario (obstetricians, midwives, family physicians, pediatricians, and nurses). Univariate and multivariate analyses were used to investigate the effects of core beliefs, perceived barriers, and demographic characteristics on the reported frequency of informing parents about NBS before sample collection.

RESULTS: Virtually all of the midwives and almost half of the nurses reported discussing NBS with parents, whereas less than one sixth of the physicians did so. Providers who perceived a responsibility to inform parents were 3 times more likely to report doing so than those who did not perceive this responsibility (odds ratio: 2.9 [95% confidence interval: 2.1–4.1]). Those who lacked confidence to inform parents were 70% less likely to discuss NBS with parents compared with those who did not experience this cognitive barrier (odds ratio: 0.3 [95% confidence interval: 0.2–0.4]). Controlling for these covariates, family physicians and obstetricians were more likely than pediatricians to inform parents.

CONCLUSIONS: These results provide guidance for capacity building among providers who are positioned to inform parents about NBS before sample collection. Our findings call for targeted educational interventions that consider patterns of provider practice related to prenatal and NBS care, seek to redress confidence limitations, and engage key provider groups in the importance of this professional responsibility.

METHODS: This is a secondary analysis of data from validated questionnaires provided to adolescents (>12 years old) diagnosed with cancer and parents of children with cancer at 3 sites in Canada (Halifax, Vancouver, and Montreal) and 2 in the United States (Atlanta, GA, and Memphis, TN). Respondents reported their own research participation and cited factors that would influence their own decision to participate in, or to provide parental authorization for their child to participate in health research.

RESULTS: Completed questionnaire rates for AYAs and parents were 86 (46.5%) of 185 and 409 (65.2%) of 627, respectively. AYAs (n = 86 [67%]) and parents (n = 409 [85%]) cited that they would participate in research because it would help others. AYAs perceived pressure by their family and friends (16%) and their physician (19%). Having too much to think about at the time of accrual was an impediment to both groups (36% AYAs and 47% parents). The main deterrent for AYAs was that research would take up too much time (45%). Nonwhite parents (7 of 56 [12.5%]) were more apt to decline than white parents (12 of 32 [3.7%]; P < .01).

CONCLUSIONS: AYAs identified time commitment and having too much to think about as significant impediments to research participation. Addressing these barriers by minimizing time requirements and further supporting decision-making may improve informed consent and impact on enrollment in trials.

METHODS: We assessed our Sudden Death in Young Athletes Registry, 1980–2008, to formulate a clinical profile of those sudden deaths attributed to commotio cordis (and other causes) occurring in competitive lacrosse, the most rapidly growing youth sport in the United States.

RESULTS: Twenty-three sudden deaths or cardiac arrests were identified in high school and college lacrosse participants. Ages were 18 ± 2 years; each athlete was male. Ten died after blunt precordial blows, including 4 goalies wearing commercially available chest protectors. Twelve others collapsed because of presumed or documented cardiovascular disease, including hypertrophic cardiomyopathy, long QT syndrome, mitral valve prolapse, or ruptured cerebral aneurysm. The mortality rate associated with lacrosse was 1.46 deaths per 100000 person-years and was similar to that of other sports including baseball, basketball, football, and hockey. However, deaths attributed to commotio cordis were more frequent in lacrosse (0.63 deaths per 100000 person-years) than in other sports (P < .02), with the exception of hockey.

CONCLUSIONS: Sudden deaths in competitive lacrosse participants are rare and no more common than in most other sports. These catastrophic events were caused disproportionately by commotio cordis and included athletes wearing chest barriers, thereby underscoring the importance of developing effective chest protection to create a safer athletic environment for our youth.
