Randomized Controlled Trial Clinical Trial
Clinical, endocrine and metabolic effects of metformin added to ethinyl estradiol-cyproterone acetate in non-obese women with polycystic ovarian syndrome: a randomized controlled study.
Oral contraceptive pills (OC) are usually the first choice of treatment for polycystic ovarian syndrome (PCOS), when fertility is not desired. However, they do not improve, or may even further induce impairment of insulin sensitivity, which is already impaired in women with PCOS. In this prospective, randomized study, we analysed the additional benefits of adding metformin to the OC treatment in non-obese women with PCOS. ⋯ Adding metformin to the OC treatment may improve the insulin sensitivity, and may further suppress the hyperandrogenaemia in non-obese women with PCOS.

Randomized Controlled Trial Multicenter Study Clinical Trial
A multicentre randomized controlled trial of oral misoprostol and i.m. syntometrine in the management of the third stage of labour.
Postpartum haemorrhage accounts for nearly 28% of maternal mortality in developing countries. Syntometrine is an effective and commonly used oxytocic in preventing postpartum haemorrhage, but it requires a controlled storage environment and i.m. administration. Misoprostol is an orally active uterotonic agent. ⋯ The need for additional oxytocic injection was significantly higher in the misoprostol group [relative risk (RR) 1.62, 95% confidence interval (CI) 1.34-1.96], but that of manual removal of placenta was reduced (RR 0.29, 95% CI 0.09-0.87). Shivering and transient pyrexia were more common in the misoprostol group. Oral misoprostol might be used in the management of the third stage, especially in situations where the use of syntometrine is contraindicated and facilities for storage and parenteral administration of oxytocics are limited.

Randomized Controlled Trial Comparative Study Clinical Trial
Midazolam/ketamine sedative combination compared with fentanyl/propofol/isoflurane anaesthesia for oocyte retrieval.
Assisted reproduction may be associated with repeated occasions of surgical intervention. Propofol, which is frequently used for induction of anaesthesia in such procedures, has been suspected of damaging oocytes. We compared in a randomized prospective design the use of general anaesthesia with fentanyl 0.017 mg/kg, propofol 2.5 mg/kg and isoflurane to that of sedation with midazolam 0.06 mg/kg and ketamine 0.75 mg/kg for transvaginal oocyte retrieval in 50 patients with no premedication. ⋯ No patient recalled any pain sensation during the procedure. The rate of embryo transfers and pregnancies were not different between the two groups. We conclude that the sedative combination of midazolam and ketamine for oocyte retrieval may serve as an alternative for general anaesthesia.

Randomized Controlled Trial Clinical Trial
Randomized trial of misoprostol and cervagem in combination with a reduced dose of mifepristone for induction of abortion.
Mifepristone (600 mg) in combination with a prostaglandin has been demonstrated to be a safe, acceptable alternative to vacuum aspiration for induction of abortion in the first 9 weeks of pregnancy. However, the efficacy and side-effects of different prostaglandins used in combination with mifepristone have not been assessed in a randomized trial. In this study, 800 women seeking an abortion at gestational age < or = 63 days amenorrhoea were randomized to receive either 0.5 mg gemeprost by vaginal pessary (group I) or 600 micrograms misoprostol (group II) by mouth approximately 48 h after taking 200 mg mifepristone by mouth. ⋯ However, there were significantly more ongoing pregnancies in the women who received misoprostol than in those who received gemeprost (nine versus one, P < 0.01) and in eight of these 10 women the gestation was > 49 days. Fewer women in group II required analgesia than in group I (48 versus 60%, P < 0.001) although the number requesting opiate was similar in each group (6.9 versus 5.2%, P > 0.4). The incidence of nausea and vomiting after misoprostol (47.8 and 21.9% respectively) was higher (P < 0.001) than after gemeprost (33.9 and 12% respectively).(ABSTRACT TRUNCATED AT 250 WORDS)
