Tissue adhesives incorporate the qualities of an ideal skin-closure material. The results demonstrate their advantage over the current standard suture-based methods of repair in the perineum. The use of adhesives merits further evaluation.
Summary. A double‐blind placebo‐controlled trial was performed in 20 primigravidae to assess the physiological and clinical effects of oral mifepristone on myometrial contractility and sensitivity in the second trimester. Ten women received 600 mg of oral mifepristone and 10 women a placebo 24 h before abortion was induced in both groups, with extra‐amniotic PGE2 instillation. Intrauterine pressure recordings demonstrated increased spontaneous uterine activity and increased sensitivity to PGE2 and ergometrine, but no change in oxytocin sensitivity after mifepristone treatment. There were no significant differences in PGE or PGF metabolite concentrations in peripheral maternal plasma over the 24‐h study period after treatment between the mifepristone and placebo groups. The mean induction abortion interval in the mifepristone group was 512 (SD 321) min compared with 1128 (SD 606) min in the placebo group (P≤0.02). The mechanism whereby mifepristone provokes enhanced uterine contractility and sensitivity to prostaglandins, with a reduction in abortion times, does not appear to be through endogenous production of PGE or PGF.
A double-blind, placebo controlled clinical trial was conducted to assess the clinical and physiological effects of 'epostane', a progesterone synthesis inhibitor, in mid-trimester prostaglandin termination of pregnancy. Mean peripheral progesterone levels had fallen by 74% after 72 h in the patients treated wtih epostane. The mean induction-abortion interval in the treatment group was 490 (SD 271) min, comparcd with 1432 (SD 640) min in the control group. Intrauterine pressure recording demonstrated increased sensitivity to prostaglandin E2 after epostane treatment but no change in oxytocin sensitivity. The clinical implications of facilitated induction of abortion are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
