Amniotic fluid index as a predictor of latency after preterm premature rupture of the membranes.

To determine if latency following preterm premature rupture of membranes can be predicted using the amniotic fluid index, a retrospective observational study was performed using patient records to identify those admitted with a diagnosis of preterm premature rupture of membranes. Fifty-one patients with initial evaluation within 48 hours of rupture and gestational age 26 to 34 weeks were identified. Amniotic fluid index was evaluated along with a biophysical profile; these were followed serially until delivery.

The serum insulin-like growth factor-II/mannose-6-phosphate receptor in normal and diabetic pregnancy.

The extracellular domain of the insulin-like growth factor-II/mannose-6-phosphate (IGF-II/Man-6-P) receptor is present in the circulation of several species including man. The purpose of the present study was to establish whether this truncated receptor is present in higher concentrations in fetal sera compared with adult sera and whether the metabolic status of the individual alters serum concentrations of this protein. Nondiabetic and diabetic pregnant women were studied throughout gestation, and at term fetal cord sera were obtained.

Prenatal diagnosis and obstetric management of Larsen syndrome.

Background: Larsen syndrome is a disease of generalized defect in collagen formation including multiple disorders of the joints and cardiac anomalies. A review of the literature revealed no previous reported cases in pregnancy.

Case: A 29-year-old woman with known Larsen syndrome thought to be of the autosomal recessive type presented in pregnancy; second-trimester ultrasound suggested fetal involvement with Larsen syndrome.

Vaginal birth after cesarean section: the patient's point of view.

Advocacy of vaginal birth after cesarean section (VBAC) is the current standard of care. We interviewed patients in our program about their attitudes toward VBAC and cesarean section. The success rate in our VBAC program is similar to rates reported in the literature (65 percent).

The clinical significance of resolving polyhydramnios.

Polyhydramnios is associated with multiple maternal and fetal abnormalities. Although the risks of persistent polyhydramnios are well described, the clinical implications of polyhydramnios that resolves prior to delivery are not. Thirty-four non-diabetic patients with resolving polyhydramnios were studied.
