Resistance to activated protein C and the leiden mutation: high prevalence in patients with abruptio placentae.

Objective: The Leiden mutation, a point mutation in the gene encoding coagulation factor V, is associated with a high frequency of thromboembolic phenomena. It has recently been connected with adverse outcomes of pregnancy. We carried out this study to define its connection with abruptio placentae.

Individual implantation rate: proposal for a new index for evaluation of assisted reproduction results.

Objective: To assess whether implantation in assisted reproductive technology (ART) cycles is a random event.

Design: Retrospective analysis of results.

Setting: Division for Reproductive Endocrinology and ART, Department of Obstetrics and Gynecology, Haemek Medical Center, Afula, Israel.

[Ultrasonographic diagnosis of amniotic band syndrome in pregnancy].

The amniotic band syndrome comprises a heterogenous group of congenital deformities which originate from rupture of the amnion during the early stages of fetal development. The diagnosis of the syndrome in the newborn is difficult because of the wide spectrum of anomalies, and its resemblance to other genetic or developmental deformities. The prenatal diagnosis of the syndrome is possible when there is ultrasonographic demonstration of multiple, nonembryological anomalies, with or without visualization of amniotic bands floating in the amniotic fluid.
