SUMMARY The progress in pregnancy of a female with myophosphorylase deficiency (McArdle's disease) is described. In spite of the increased muscular effort expended, both pregnancy and labour were normal and the muscle symptoms unchanged, suggesting that compensatory mechanisms might have operated. These possible mechanisms are discussed. Women suffering from the myopathy need not expect any deterioration during pregnancy.

Summary A case of acardius amorphus is reported. The rarity of foetal monsters without a functioning heart is emphasized and the method of classification reviewed. The theories of teratogenesis are discussed. Evidence is presented in support of the theory that there is a primary failure of the organ to develop. The possibility of anoxia and nutritional deficiency of the foetus being solely responsible for the malformation seems unlikely.

Summary A prospective study of 1353 labours and the relevant newborn failed to reveal any significant difference between the incidence of neonatal hyperbilirubinaemia (defined as a level of 12 mg. or more per 100 ml.) following spontaneous labour, and after labour induced or accelerated by oxytocin. The incidence of unexplained neonatal hyperbilirubinaemia after spontaneous labour was 6.3 per cent. Following induced labour however there was a highly significant (P<0 00l) association between the mean total dose of oxytocin used for induction and the incidence of neonatal hyperbilirubinaemia. The proportion of babies who developed hyperbilirubinaemia increased in direct relation to the total dose of oxytocin used for the induction. In this series the incidence of hyperbilirubinaemia increased sharply when the total dose of oxytocin exceeded 20 units as it did in 12 per cent of induced labours. No association was demonstrated between neonatal hyperbilirubinaemia and birthweight, or duration of spontaneous labour. When labour was induced, however, the proportion of newborn babies with hyperbilirubinaemia increased with the duration of labour. The significance of these findings is discussed.

Conception had occurred despite the presence of a 'Gravigard' copper-releasing intrauterine contraceptive device (IUCD). She gave a history of congenital heart disease for which she had had surgery on two occasions. At 11 years of age an atrial septal defect (ASD) had been repaired. This operation was unsuccessful and further surgery was performed at the age of 16 years. At that time, in addition to the ASD she was found to have both mitral and tricuspid incompetence. The ASD was closed and a tricuspid anuloplasty carried out. The mitral valve was not repaired. Postoperatively she was left with mild residual tricuspid and mitral incompetence but was asymptomatic.
