ABSTRACT
OBJECTIVE: To examine associations with morbidly adherent placenta (MAP) among women with placenta previa. STUDY DESIGN: Women with MAP (cases) and previa alone (controls) were identified from a cohort of 236,714 singleton pregnancies with both first and second trimester prenatal screening, and live birth and hospital discharge records; pregnancies with aneuploidies and neural tube or abdominal wall defects were excluded. Logistic binomial regression was used to compare cases with controls. RESULT: In all, 37 cases with MAP and 699 controls with previa alone were included. Risk for MAP was increased among multiparous women with pregnancy-associated plasma protein-A (PAPP-A) ⩾95th percentile (⩾2.63 multiple of the median (MoM); adjusted OR (aOR) 8.7, 95% confidence interval (CI) 2.8 to 27.4), maternal-serum alpha fetoprotein (MS-AFP) ⩾95th percentile (⩾1.79 MoM; aOR 2.8, 95% CI 1.0 to 8.0), and 1 and ⩾2 prior cesarean deliveries (CDs; aORs 4.4, 95% CI 1.5 to 13.6 and 18.4, 95% CI 5.9 to 57.5, respectively). CONCLUSION: Elevated PAPP-A, elevated MS-AFP and prior CDs are associated with MAP among women with previa.

OBJECTIVE: To compare the efficacy of oral misoprostol to vaginal dinoprostone for labor induction in nulliparous women. STUDY DESIGN: Admissions for labor induction from January 2008 to December 2010 were reviewed. Patients receiving oral misoprostol were compared with those receiving vaginal dinoprostone. The primary outcome was time from induction agent administration to vaginal delivery. Secondary outcomes included vaginal delivery within 24 h, mode of delivery and maternal and fetal outcomes. RESULT: A total of 680 women were included: 483 (71%) received vaginal dinoprostone and 197 (29%) received oral misoprostol. Women who received oral misoprostol had a shorter interval to vaginal delivery (27.2 vs 21.9 h, P<0.0001) and were more likely to deliver vaginally in <24 h (47% vs 64%, P=0.001). There was no increase in the rate of cesarean delivery or adverse maternal or neonatal outcomes. CONCLUSION: Labor induction with oral misoprostol resulted in shorter time to vaginal delivery without increased adverse outcomes in nulliparous women.
