Office hysteroscopy before first in vitro fertilization. A randomized controlled trial.

Background: Implantation failure remains a mystery since decades. This procedure needs a "top quality embryo" and a "normal" uterine cavity. To assess uterine cavity before first in vitro fertilization (IVF), many diagnostic tools could be used.

Role of fetal sex in the outcome of antenatal glucocorticoid treatment to prevent respiratory distress syndrome: systematic review and meta-analysis.

Background: Antenatal glucocorticoid (AGC) therapy has been associated with a decrease in respiratory distress syndrome (RDS). While preterm males remain at greater risk of RDS than females, the role of fetal sex in AGC response is not well known.

Objectives: To review the available evidence regarding the effect of fetal sex in the prevention of RDS using AGC.

Sublingual misoprostol for first trimester termination of pregnancy.

Objectives: To compare blood loss, efficiency, and acceptability of repeated doses of sublingual misoprostol with the standard Tunisian regimen of mifepristone-misoprostol for first trimester medical abortion.

Methods: A prospective randomized trial of 252 healthy pregnant women requesting medical abortion in the first trimester (up to 56 days). Participants were randomized to receive 200mg of oral mifepristone followed by 400 microg of oral misoprostol (group 1) or 800 microg of sublingual misoprostol repeated every 4 hours for up to a maximum of 3 doses (group 2).
