Randomized Controlled Trial Comparative Study Clinical Trial
Child mortality after high-titre measles vaccines: prospective study in Senegal.
The use of Edmonston-Zagreb high-titre (EZ-HT) vaccine at age 6 months has been recommended for countries in which measles before the age of 9 months is a substantial cause of death, but little is known about the long-term effects of high-titre live measles vaccines given early in life. In a randomised vaccine trial in a rural area of Senegal, children were randomly assigned at birth to three vaccine groups: EZ-HT at 5 months (n = 336); Schwarz high-titre (SW-HT) at 5 months (n = 321); and placebo at 5 months followed by standard low-titre Schwarz vaccine at 10 months (standard: n = 358). All children were prospectively followed for 24-39 months in a well-established demographic surveillance system. ⋯ The three vaccine groups were comparable as regards various social, family, and health characteristics, and there was no difference in mortality between children who received the standard vaccine and those who were eligible for the trial but did not take part for various reasons. The higher risk of death in the two high-titre vaccine groups remained significant in multivariate analyses. These findings suggest a need to reconsider the use of high-titre measles vaccines early in life in less developed countries.

Randomized Controlled Trial Comparative Study Clinical TrialOral ciprofloxacin versus ceftriaxone for the treatment of urethritis from resistant Neisseria gonorrhoeae in Zambia.
Neisseria gonorrhoeae strains resistant to treatment with penicillin, tetracycline, and/or spectinomycin are increasing in prevalence in many parts of the world. In Zambia, 52% of N. gonorrhoeae isolates produced beta-lactamase in 1986. Few oral regimens have proven effective for treatment of resistant N. gonorrhoeae. ⋯ Chlamydia trachomatis in urethral exudate was found by direct fluorescent-antibody microscopic examination or by culture in 10 (5%) participants. All N. gonorrhoeae isolates were inhibited by ceftriaxone at 0.06 micrograms/ml, except one which was inhibited at 0.125 micrograms/ml, while ciprofloxacin inhibited all isolates at 0.03 micrograms/ml. Ciprofloxacin is a safe and effective therapy for uncomplicated gonococcal urethritis, including that caused by PPNG and CMRNG in human immunodeficiency virus-infected men.

Randomized Controlled Trial Clinical TrialEffect of intraperitoneal instillation of 32% dextran 70 on postoperative adhesion formation after tubal surgery.
The intraperitoneal instillation of 32% dextran 70 (HyskonR, Pharmacia AB, Sweden) has previously been reported to prevent the formation of postoperative adhesions. Against this background, the present study was undertaken to evaluate the efficacy of HyskonR in counteracting peritoneal adhesions following tubal microsurgery. 105 infertile women were operated upon in a prospective, randomized, controlled, double-blind, multicenter study. ⋯ The extent of adhesions in the Hyskon group was not lesser than in the saline group, however. The pregnancy rates in the two groups were also similar.

Randomized Controlled Trial Comparative Study Clinical TrialA randomized prospective study of the use-effectiveness of two methods of natural family planning.
The final results of a prospective comparative study of two methods of natural family planning indicate a significant difference in the 12 month net cumulative pregnancy rates between the ovulation and symptothermal methods. These differences are on the order of two to one in favor of the symptothermal method. ⋯ Dropout rates for both methods were high. Lack of interest or dissatisfaction with the method was the major reason for dropout training while pregnancy or desire for pregnancy were the major reasons for dropout during the formal phase of the study.

Randomized Controlled Trial Clinical Trial
Steroids in the treatment of clinical septic shock.
A prospective (Part I) and a retrospective (Part II) study were used to determine the safety and efficacy of corticosteroids in the treatment of septic shock. In Part I, 172 consecutive patients in septic shock admitted over an 8-year period were treated with either steroid or saline: 43 received dexamethasone (DMP), 43 received methylprednisolone (MPS), and 86 received saline. The study was double-blind and randomized, and the three groups were compared for age, severity of shock, presence of underlying disease, and year of study. ⋯ Again, the two groups of patients were compared for severity of shock, underlying disease, age, and year of study. Mortality among patients treated without steroid was 42.5% (68/160) and among patients treated with steroid was 14% (24/168); there was no significant difference in mortality rate between DMP- and MPS-treated patients. In Parts I and II combined, complications occurred in 6% of steroid-treated patients with no significant difference between DMP- and MPS-treated groups.
