Multicenter StudyAssociations between 2 polymorphisms in the methylenetetrahydrofolate reductase gene and placental abruption.
Heritable thrombophilias have been implicated as a potential cause of abruption by vascular disruption at the uteroplacental interface. Polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) gene have been linked to vascular complications outside of pregnancy, which includes stroke. Given the underlying thrombotic nature of abruption, we hypothesized that polymorphisms in the MTHFR gene are associated with abruption. ⋯ In this population, neither heterozygosity nor homozygosity for the 677C-->T and 1298A-->C variants in MTHFR was associated with placental abruption.

Comparative StudyCase-control comparison of cesarean hysterectomy with and without prophylactic placement of intravascular balloon catheters for placenta accreta.
The objective of the study was to compare outcomes of women with placenta accreta who underwent cesarean hysterectomy with and without prophylactic intravascular balloon catheters. ⋯ Prophylactic intravascular balloon catheters did not benefit women with placenta accreta undergoing cesarean hysterectomy.

Liver position and lung-to-head ratio for prediction of extracorporeal membrane oxygenation and survival in isolated left congenital diaphragmatic hernia.
The purpose of this study was to determine the ability of liver position and lung-to-head ratio to predict outcome in isolated left congenital diaphragmatic hernia. ⋯ Liver position is the best prenatal predictor of outcome in isolated left congenital diaphragmatic hernia. Lung-to-head ratio alone should not be used to counsel families regarding mid gestational management choices.
