Case Reports5-oxoprolinuria: biochemical observations and case report.
We have studied a patient with 5-oxoprolinuria who presented with hemolysis and metabolic acidosis as a neonate; he has had normal growth and development to one year of age. Compensated hemolytic anemia persists, and he requires alkalinizing agents for correction of acidosis. ⋯ Genetic heterogeneity was apparent on comparative study of glutathione synthetase kinetics in cells from two patients with this disorder. The consequences of the deficiency of glutathione synthetase, decreased intracellular glutathione, and overproduction of 5-oxoproline are discussed with reference to the possible cellular roles of these compounds.

Randomized Controlled Trial Clinical TrialUse of nalotone to to reverse narcotic respiratory depression in the newborn infant.
Twenty neonates whose mothers had received meperidine (1.0 to 1.5 mg/kg) intravenously within three hours of delivery were studied to determine the effectiveness of naloxone in reversing neonatal respiratory depression. The following measurements were carried out within 20 to 30 minutes after delivery: minute ventilation, end tidal CO2, and ventilatory response to CO2. These determinations were repeated after administration of either placebo or naloxone, 0.01 mg/kg intramuscularly. ⋯ After administration of placebo the test results did not change significantly. After administration of naloxone, VE increased significantly (P less than 0.05) and the slope of the CO2 response curve doubled (P less than 0.001). Naloxone effectively reverses narcotic depression of the respiratory center in the newborn infant.

Hypotension and bradycardia associated with airblock in the neonate. Preliminary report.
The hospital courses of 19 infants were analyzed retrospectively to determine if there was a relationship between hypotension and extra-alveolar air: interstitial emphysema, pneumomediastinum, and penumothorax. Of the 16 infants who subsequently developed PT, 12 had hypotension with IE/PM from one to 86 hours prior to the onset of PT (median 6.5 hours). ⋯ Four of the six infants of greater than or equal to 38 weeks' gestation had bradycardia throughout the duration of EAA. Hypotension and bradycardia appear to be associated with airblock and thus may alert the physician to those infants who are at greatest risk for developing PT.
