We report the results of a large-scale trial with mifepristone (RU 486) followed by the administration of a prostaglandin (PG) analogue for the medical termination of early pregnancy. Altogether, 16,173 patients from 300 centers were evaluated. 48 women (0.3%) were lost to follow-up prior to, and 416 (2.6%) after the PG administration, and therefore the efficacy was evaluated in 15,709 women. Overall, the success rate was 95.3%, with no statistical difference regarding the nature and dose of PG used. The median duration of bleeding was 8 days, being 12 days or less in 89.7% of the women. Bleeding was significant enough to necessitate a vacuum aspiration or a dilatation and curettage in 0.8% of the cases. A blood transfusion was necessary in 0.1% of the women (11 patients). Serious cardio-vascular side-effects were reported in 4 cases after the PG (sulprostone) injection: they consisted of one acute myocardial infarction attributed to a coronary spasm, and in marked hypotension in the other 3 women. All patients recovered uneventfully. In conclusion, RU 486 followed by a PG analogue provides an efficient and safe medical alternative to surgery for early pregnancy termination, provided that the recommended protocol is adequately followed and the contraindications to prostaglandins are respected.

In 2115 women seeking voluntary termination of pregnancy after 49 days of amenorrhea or less, we studied the effect of a single 600-mg dose of mifepristone (RU 486), followed 36 to 48 hours later by the administration of one of two prostaglandin analogues, either gemeprost (1 mg by vaginal suppository) or sulprostone (0.25, 0.375, or 0.5 mg by intramuscular injection). The women were monitored for four hours after prostaglandin administration. Efficacy was indicated by the complete expulsion of the conceptus without the need of an additional procedure. All other results were considered failures, and the pregnancy was then terminated by a surgical method. The overall efficacy rate was 96.0 percent (95 percent confidence interval, 95.0 to 96.8). The failures included persisting pregnancies (1.0 percent), incomplete expulsions (2.1 percent), and the need for hemostatic procedure (0.9 percent). The mean time to expulsion was significantly shorter when sulprostone was given in the high dose (4.5 hours) than when it was given in the two lower doses (13.1 and 19.3 hours) or when gemeprost was given (22.7 hours). The mean duration of uterine bleeding was 8.9 days (range, 1 to 35); one woman received a blood transfusion. Most women had transient abdominal pain after receiving prostaglandin, but there were few other side effects. We conclude that the administration of mifepristone followed by a small dose of a prostaglandin analogue is an effective and safe method for the early termination of pregnancy.

A prospective, randomized, multicentre trial was conducted to evaluate the efficacy and safety of roxithromycin (150 mg b.i.d. orally) and penicillin (2.5 MU x 8 daily intravenously, then 6 MU daily orally) in the treatment of hospitalized adult patients with erysipelas. Seventy-two patients entered the study. Thirty-one patients in the roxithromycin group and 38 patients in the penicillin group completed the trial. The overall efficacy rates (cure without additional antibiotics) were 84% (26/31) in the roxithromycin group and 76% (29/38) in the penicillin group (P = 0.43). No side-effects were observed in the roxithromycin-treated patients whereas rashes occurred in two cases in the penicillin group, leading to exclusion from the study. Oral roxithromycin can thus be considered an effective and well-tolerated treatment for erysipelas in adult hospitalized patients.

For patients with acute low back pain, normal activity is at least equivalent to bed rest. The findings of this study indicate that prescriptions for bed rest, and thus for sick leaves, should be limited when the physical demands of the job are similar to those for daily life activities.
