Specific Diagnostic Practice
Chairman Collins-Williams: The specific diagnosis of the child with respiratory allergy comprises the following: (1) general pediatric care; (2) careful allergic history; (3) complete physical examination; (4) indicated laboratory procedures including nasal smears; (5) skin testing.
Skin testing is necessary in order to help determine the specific etiologic allergens. The allergens tested with should include the common foods and the common inhalants, pollens and molds in the environment.
Eosinophiles and Eosinophilia
Eosinophilia occurs in a great many conditions other than allergy and these must be taken into account in interpreting differential blood counts.
The nasal smear is a useful laboratory test in the diagnosis of nasal allergy. Eosinophiles may temporarily appear in considerable numbers in the nasal smear of the nonallergic child during recovery from a respiratory infection, but otherwise a predominance of eosinophiles in the nasal smear is diagnostic of nasal allergy.
Office Treatment of Respiratory Allergy
The office treatment of a child with respiratory allergy includes the following: (1) general pediatric care; (2) symptomatic relief of allergic symptoms; (3) removal of incriminated foods from the diet; (4) as complete an elimination of environmental allergens as possible; (5) specific desensitization.
Dr. Ratner: The method of specific desensitization which we use in practice is as follows:
The treatment extract consists of a 1:5,000 dilution of each of the inhalants, pollens and molds with which the patient gave a positive reaction. Each week the patient receives one injection from a tuberculin syringe containing 0.15 cc. of this treatment extract, 0.15 cc. of a 1:20 dilution of mixed bacterial vaccine, 0.15 cc. of a 1:20 dilution of pertussis vaccine, and 2 minims of adrenaline.
