Emergency cervical cerclage in twin and singleton pregnancies with 0-mm cervical length or prolapsed membranes.

Introduction: Cervical cerclage is controversial in twin pregnancies, although recent data from the USA supports its use where "physical examination-indicated". Limited data exist, however, in the extreme situation of 0-mm ultrasound-measured cervical length or even prolapsed membranes. This research compares the success of emergency cervical cerclage in multiple and singleton pregnancies.

External cephalic version after previous cesarean section: A cohort study of 100 consecutive attempts.

Objective: External cephalic version is commonly not performed in women with a previous cesarean section. Fear of uterine rupture and cesarean section in labor are prominent. The risks, however, of these are unclear.

Examination of the association between male gender and preterm delivery.

Objective: To examine possible reasons why a male fetus constitutes a risk factor for preterm delivery.

Study Design: Retrospective study of deliveries from hospital database in a UK teaching hospital. The population comprised all deliveries >23 weeks over an 11-year period, excluding multiples, terminations and pregnancies with major abnormalities including indeterminate gender.

The relationship between intrapartum maternal fever and neonatal acidosis as risk factors for neonatal encephalopathy.

Objectives: This study was undertaken to investigate the relationship among maternal intrapartum fever, neonatal acidosis, and the risk of neonatal encephalopathy.

Study Design: Cohort study of pregnancies at term. Logistic regression was used to estimate the effect of maternal fever and acidosis on the risk of neonatal encephalopathy.
