Factors affecting neonatal jaundice.

Plasma bilirubin was estimated on 690 term infants on about the 6th day of life. Perinatal factors were recorded and the results analysed. Hyperbilirubinaemia was defined as a level greater than 205 micromol/1 (12 mg/100 ml) and this was present in 20% of cases. Three factors--epidural analgesia, breast feeding, and poor weight recovery--showed highly significant associations with jaundice. The relative importance of these is discussed and compared with recent reports. Induction of labour, for reasons other than postmaturity, and a gestational age less than 39 weeks showed a slightly increased incidence of jaundice. There was no correlation with other factors tested including oxytocic drug administration. Despite the high incidence (20%) of hyperbilirubinaemia, only 2.5% infants needed treatment and none required exchange transfusion. Radical changes in obstetric management or infant feeding are not indicated.

Carbon monoxide and ventricular fibrillation threshold in dogs with acute myocardial injury.

In a blind, randomized study, the effect of breathing 100 p.p.m. of CO versus compressed, purified air for 2 hours on ventricular fibrillation threshold (VFT) was investigated in 21 dogs with acute myocardial injury. The mean arterial carboxyhemoglobin was 1.16 per cent in the air control period, 1.07 per cent after air, 1.08 per cent in the CO control period, and 6.34 per cent after CO. In comparison to air, CO increased the mean arterial carboxyhemoglobin (P less than 0.001). One dog developed spontaneous ventricular fibrillation 100 minutes after CO. Mean VFTs in the other 20 dogs were 12.8 +/- 6.8 milliamperes after CO, 11.2 +/- 6.0 milliamperes in the air control period, and 15.0 +/- 5.1 milliamperes after air. In comparison to air, CO decreased the VFT (P less than 0.001). These data show that breathing 100 p.p.m. of CO for 2 hours reduces the VFT in dogs with acute myocardial injury.

Cervical neurogenic tumors presenting as thoracic apical masses in infants and children.

Seven cases of cervical neurogenic tumor presented in an almost identical manner roentgenographically; a polypoid extrapleural mass at the lung apex. The association of neuroblastoma with Horner syndrome and heterochromia of the irides is mentioned. Characteristic roentgen appearance should be appreciated due to good prognosis of cervical neuroblastoma with prompt therapy.

Neurological disturbance in a phenylketonic child after discontinuation of dietary treatment.

Signs of moderately severe spastic diplegia appeared in 14-year-old late-treated phenylketonuric boy 13 months after dietary restrictions were lifted. The literature contains reports of untreated phenylketonuric patients developing demyelinating conditions in later childhood. The possible implications of relaxing the diet in early- and late-treated cases of phenylketonuria are discussed.

Sequelae of neonatal jaundice.

A total of 371 newborn infants falling into 3 groups, non-haemolytic jaundice, haemolytic jaundice, and non-jaundiced controls, have been reassessed in the 6th year of life as regards neurological, audiological, and psychological function. Neurological handicap was concentrated among the infants of low birth weight and was not related to jaundice, apart from one case of athetoid cerebral palsy with deafness. No other cases of perceptive deafness were discovered. Intelligence testing on the Stanford Binet scale showed no relation between depth of jaundice and I.Q.These findings support the majority of reports in the literature that reduction in intelligence does not occur in non-haemolytic jaundiced babies with serum bilirubin below about 20 mg./100 ml. In haemolytic jaundice slight doubt remains. There is no indication for changing present standards for exchange transfusion.
