Maintenance tocolytics for preterm symptomatic placenta previa: a review.

The purpose of the review article is to determine if prolonged (≥48 hour) tocolytics with symptomatic preterm placenta previa improves perinatal outcome. OVID MEDLINE and Cochrane Databases were searched from January 1950 to January 2009. Odds ratio (OR) and 95% confidence intervals (CI) were calculated.

Evidence-based medicine in obstetrics: can levels B and C recommendations be elevated to level A recommendations?

In this study, 65% (132/195) of level B/C obstetric recommendations are amenable to randomized clinical trials (RCTs) and seven were identified as most needed. The purpose of the survey was to evaluate levels B and C recommendations in obstetric practice bulletins (PBs) regarding the feasibility of performing RCT to elevate each subject to level A evidence. Eleven geographically dispersed physicians with experience in research reviewed levels B and C recommendations for the ethical and logistical feasibility of performing an RCT.

Predicting the outcome of newborns with gastroschisis.

Objective: The objective of the study was to determine factors predicting outcome in newborns with gastroschisis.

Methods: A retrospective analysis of 155 consecutive cases admitted from 1 January 1990 to 31 December 2007 was performed. Prenatal ultrasound findings were available for 89 of 155 (57%) patients and were compared with final outcome.

Cornual heterotopic pregnancy and cornual resection after in vitro fertilization/embryo transfer. A report of two cases.

Background: Heterotopic pregnancy occurs in about 1% of pregnancies achieved with assisted reproductive technologies. The incidence of cornual pregnancy is approximately 1% of all ectopics.

Cases: Two patients became pregnant after treatment with IVF-ET.

Glucose metabolism during fasting through human pregnancy: comparison of tracer method with respiratory calorimetry.

Glucose turnover and glucose oxidation were quantified in six normal pregnant women serially throughout pregnancy, using [U-13C]glucose tracer in combination with open-circuit indirect respiratory calorimetry. Five normal nonpregnant women were studied for comparison. With advancing gestation and increase in maternal body weight, there was a proportionate increase in the rate of appearance (Ra) of glucose so that Ra expressed per kilogram body weight did not change from the first to third trimester.
