Effect of validated skills simulation on operating room performance in obstetrics and gynecology residents: a randomized controlled trial.

Objectives: To estimate whether training on previously validated laparoscopic skill stations translates into improved technical performance in the operating room.

Methods: We performed a multicenter, randomized, controlled trial evaluating the performance of a laparoscopic bilateral midsegment salpingectomy. Residents were randomized to either traditional teaching (no simulation) or faculty-directed sessions in a simulation laboratory.

Cesarean delivery and respiratory distress syndrome: does labor make a difference?

Objective: The purpose of this study was to determine if cesarean delivery is a risk factor for respiratory distress syndrome (RDS) and if this risk is modified by labor before cesarean.

Study Design: This population-based case-control study compared 4778 cases of RDS to 5 times as many controls.

Results: Unadjusted, cesarean delivery was associated with RDS, odds ratio (OR) 3.
