Acute proliferative glomerulonephritis with crescents and renal failure in pregnancy successfully managed by intermittent haemodialysis. Case report.

A 26-year-old patient with no previous history of renal disease developed acute non-streptococcal crescentile glomerulonephritis with severe renal failure in the 17th week of her second pregnancy. It became necessary to treat her with haemodialysis to maintain the blood urea around 25 mmol/l. The haemoglobin was maintained above 9 g/dl with regular blood transfusion and the blood pressure was controlled with hypotensive drugs. Measurement of fetal biparietal diameter and human placental lactogen indicated normal fetal growth and placental function. The patient spontaneously delivered a healthy infant at 32 weeks. Haemodialysis requirements decreased post partum and the patient even managed without dialysis for 12 weeks. Renal function, however, remained severely impaired and maintenance haemodilysis was again necessary at nine months post partum. Glomerulonephritis complicating pregnancy is reviewed and the management of acute and chronic renal failure in pregnancy is discussed.

Search for superconducting regions in lysozyme.

The rate of electron transfer between a spin-labeled lysozyme molecule and a platinum electrode was measured in aqueous solution in the presence and absence of an external magnetic field of approximately 100 mT. The rate showed no significant change. This behavior is unlikely to be consistent with the regions of superconductivity in lysozyme proposed by Ahmed et al.

Postpartum haemorrhage after induced and spontaneous labour.

The labour records of 1000 consecutive deliveries were studied to compare the incidence of postpartum haemorrhage after induced labour with that after spontaneous labour. The discovery of an increased incidence of postpartum haemorrhage in the induced group prompted further analysis of the incidence of haemorrhage among 3674 normal deliveries. This analysis confirmed that the incidence of postpartum haemorrhage was increased after induction of labour; among primiparous patients the increased incidence after induced labours was nearly twice that after spontaneous labours, even when only normal deliveries were considered. These findings indicate that postpartum haemorrhage is another complication of induction that needs to be taken into account when induction is being considered.
