Cervical dysplasia in pregnancy: progression versus regression post-partum.

Objective: To assess the natural history of cervical dysplasia during pregnancy and determine the rates for progression or regression post-partum by the severity of the lesion.

Method: This was a retrospective study of 100 patients screened by PAP smear. Lesions were graded by colposcopy and biopsy, and followed post-partum.

Preterm premature rupture of the membranes is associated with asymmetric intrauterine growth retardation and smaller placentas.

Objective: To show that infants delivered prematurely because of preterm premature rupture of the membranes (PPROM) show a tendency for asymmetric intrauterine growth retardation (IUGR). At the same time, to demonstrate that these pregnancies exhibit nutritional deprivation by the presence of correspondingly smaller placentas, as demonstrated by the placental-fetal ratio.Study Design: A prospective study was performed over 2 years comparing the tendency for IUGR in infants born of pregnancies with PPROM (N = 86), as compared to normal term controls (N = 351).

Cesarean section for the second twin.

Objective: To determine the reasons for cesarean section (C/S) for the second twin following vaginal delivery of twin A, and causes of neonatal death (NND).

Study Design: Five hundred forty-one twin deliveries were studied retrospectively from 1987 to 1995. Deliveries were fractionated by fetal presentation for twin A and twin B (i.

Cocaine-associated rhabdomyolysis causing renal failure in pregnancy.

Background: Cocaine use is known to have multisystemic effects. Recently, acute renal failure as a result of rhabdomyolysis has been described as a complication of cocaine use. During pregnancy, cocaine is associated with abruptio placentae.

Neuroprotective effect of phenytoin against in utero hypoxic brain injury in fetal guinea pigs.

The present study tests the hypothesis that phenytoin, an antiepileptic agent known to block Na+ and Ca2+ channels, will prevent hypoxic brain injury in the fetus by preventing lipid peroxidation and preserving Na+,K(+)-ATPase activity. Studies were performed in 37 fetuses obtained from pregnant guinea pigs at 58-60 days gestation (term). The pregnant guinea pigs were divided into four groups: a normoxic group, a hypoxic group, a normoxic group treated with phenytoin, and a phenytoin treated hypoxic group.
