The recent study by Avery, et al. makes a significant and much needed contribution to our understanding of transient tyrosinemia in the newborn. These investigators concluded that this condition is "relatively innocuous" and that there appears to be no indication for a change in general dietary recommendations for newborn infants, although their report applies only to observations in the neonatal period. On the basis of this, the pediatrician might reasonably feel that he has no responsibility either to look for or treat this quite common delay in enzyme maturation in the premature infant.
