The effect of glucagon on spontaneous contractility of isolated pregnant uterine muscle.
To determine whether glucagon has relaxant effects on the spontaneous contractions of term pregnant human uterine smooth muscle in an isolated preparation. ⋯ These results suggest that relaxation of contractions was likely caused by the diluent rather than by glucagon. We conclude that glucagon does not have a direct relaxant effect on spontaneous contraction of isolated uterine muscle obtained from term pregnant uteri.

Case ReportsManagement of intermittent ovarian torsion by laparoscopic oophoropexy.
Ovarian torsion is a serious gynecologic condition that often results in adnexal removal. If recurrent, this can result in castration of young patients. Torsion in the pediatric population is rare, but it presents more management challenges for gynecologists. There are few reports of prophylactic oophoropexy in patients with intermittent torsion. ⋯ We believe that this is the first reported case of laparoscopic triplication of the utero-ovarian ligament to prevent recurrent torsion. In young patients, this treatment may be a reasonable alternative to oophoropexy as prophylaxis for ovarian torsion.

Randomized Controlled Trial Clinical TrialRandomized trial of oxytocin alone and with propranolol in the management of dysfunctional labor.
To compare oxytocin infusion alone and with intravenous (i.v.) propranolol in the management of dysfunctional labor. ⋯ Low-dose administration of IV propranolol in patients with dysfunctional labor augmented with oxytocin safely reduced the need for cesarean delivery, particularly among patients with inadequate uterine contractility.

Case ReportsEvaluation of fetal and uterine hemodynamics during maternal cardiopulmonary bypass.
About 4% of pregnant women have concomitant cardiac disease and a few of these do not respond to medical therapy and require surgical correction during pregnancy. We report a unique case describing fetal hemodynamics and uterine blood flow before, during, and after maternal cardiopulmonary bypass, and compare them to normal reference values in the second trimester. ⋯ Despite high peak flow rates, normal mean arterial pressure, and normothermia, fetal outcome was dismal. Nonpulsatile cardiopulmonary bypass under normothermia may not be able to meet the demands of the fetoplacental circulation.

Case ReportsSacrospinous colpopexy: management of postoperative pudendal nerve entrapment.
Sacrospinous colpopexy requires the placement of a suture through the sacrospinous ligament, under which lies the pudendal nerve. Entrapment of this nerve may result in perineal or buttock pain. This report analyzes a case of pudendal nerve entrapment and studies the management of the resultant neuropathy. ⋯ Pudendal nerve entrapment should be considered in the differential diagnosis of perineal or buttock pain after sacrospinous colpopexy. Relief of pain can be achieved even 2 years after initial surgery.
