Postpartum anal sphincter lacerations in a population with minimal exposure to episiotomy and operative vaginal delivery.

This case-control study was designed to identify risk factors for anal sphincter lacerations (ASL) in a multicultural population where episiotomies and operative vaginal deliveries are rarely performed. Cases were subjects with ASL delivered between July 1997 and June 2003. Two controls were selected for each case matched for gestational age.

Endometrial adenocarcinoma within a single horn of a didelphic uterus: a report of 2 cases.

Background: Didelphic uterus results from incomplete fusion of the müllerian ducts.

Cases: In 2 cases, endometrial adenocarcinoma arose in 1 horn of a didelphic uterus.

Conclusion: Clinicians should be aware of müllerian anomalies, which may go undetected, resulting in diagnostic delay.
