Acute abdomen in early pregnancy due to ovarian torsion following successful in vitro fertilization treatment.

Objective: Ovarian torsion is an acute abdomen requiring prompt intervention. Ovarian torsion seldom occurs during pregnancy. However, with in vitro fertilization (IVF) treatments, ovarian hyperstimulation may increase the size of the ovaries and result in the occurrence of adnexal torsion.

Multidisciplinary examination for prenatal diagnosis of posterior cervical teratoma in early second trimester.

Objective: Cervical teratomas represent approximately 3% of all congenital teratomas, which occur in approximately 1 in 20,000-40,000 live births. In this report, we present a case of congenital posterior cervical teratoma diagnosed by a two-dimensional (2D) ultrasound in the early second trimester.

Case Report: A 28-year-old woman, gravid 1, para 0, came to our prenatal clinic at 20 weeks of gestation for her first prenatal visit.

Premarin improves outcomes of spinal cord injury in male rats through stimulating both angiogenesis and neurogenesis.

Objective: To ascertain whether Premarin improves spinal cord injury outcomes in male rats by stimulating both angiogenesis and neurogenesis.

Design: Chi Mei Medical Center research laboratory.

Subjects: Male Sprague-Dawley rats 240-258 g.

Resuscitation from experimental heatstroke by estrogen therapy.

Objective: We investigated the effect of estrogen therapy on inflammatory responses, cardiovascular functions, and survival in a rat model of heatstroke.

Design: Controlled, prospective study.

Setting: Hospital medical research laboratory.

Endometrioma undergoing laparoscopic ovarian cystectomy: its influence on the outcome of in vitro fertilization and embryo transfer (IVF-ET).

Purpose: To evaluate the effect of laparoscopic ovarian cystectomy for endometrioma on the clinical outcome of IVF treatment.

Methods: Patients who received IVF treatment were retrospectively classified into two groups. Group 1 included 95 patients who received IVF due to tubal occlusion.

Vaginal disinfection with povidone iodine immediately before oocyte retrieval is effective in preventing pelvic abscess formation without compromising the outcome of IVF-ET.

Purpose: In this study, the method of employing preretrieval vaginal douching with aqueous povidone iodine is examined to see if it can decrease the incidence of pelvic abscess without compromising the clinical outcome of IVF-ET.

Methods: Patients with ovarian endometrioma and received IVF-ET treatment were retrospectively classified into two groups according to the difference of vaginal douching solution immediately before oocyte retrieval.

Results: There was no difference in the fertilization rate (81.

Comparing the clinical outcomes of intrauterine insemination by two different density gradient preparation methods.

Background: Sperm preparation has play an integral part in the success of in-vitro fertilization. The aim of this study was to compare 2 different density gradient preparations for sperm separation in respect to sperm recovery, motility, motion parameters and clinical outcome after intrauterine insemination.

Methods: One-hundred and 21 women who received intrauterine insemination due to ovulation dysfunction were randomly allocated into 2 groups, using either the Percoll (Amersham, Pharmacia Biotech AB, Sweden) or the PureSperm (Nidacon, Göteborg, Sweden) density gradient method for sperm preparation.

Agonist-induced transitions of the acetylcholine receptor.

Anti-acetylcholine receptor (AChR) monoclonal antibody 383C binds to the beta-hairpin loop alpha(187-199) of only one of the two Torpedo AChR alpha subunits. The loop recognized is associated with the alpha subunit corresponding to the high-affinity d-tubocurarine (dTC) binding site. Desensitization of the receptor with carbamylcholine completely blocks the binding of 383C.
