Letter Randomized Controlled Trial Clinical Trial
Intracluster correlation of STD prevalence in a community intervention trial in Kenya.
This study is a cluster-randomised, community intervention trial to measure the impact of female condom introduction on STD prevalence among Kenyan agricultural workers. The intracluster correlation coefficient of baseline STD prevalences at the 12 sites was 0.0011.

Randomized Controlled Trial Clinical TrialA randomized controlled trial of oxytocin administered at the end of the second stage of labor versus oxytocin administered at the end of the third stage of labor in the prevention of postpartum hemorrhage.
The general objective was to determine the incidence of postpartum hemorrhage when oxytocin was administered at the end of the second stage of labor compared to when oxytocin was administered at the end of the third stage. The specific objectives were to determine the mean amount of blood loss, duration of the third stage of labor, need for additional uterotonics and blood transfusion, incidence of hypotension and retained placenta, and mean difference in hemoglobin levels. A randomized controlled trial was conducted in a tertiary care training hospital. 130 women with term, singleton, live pregnancies in cephalic presentation who delivered vaginally were included. ⋯ There was no incidence of retained placenta. There is a trend towards a reduction of the risk of postpartum hemorrhage when oxytocin is administered at the end of the second stage of labor. This is not accompanied by an increased risk for any morbidity.

A school-based AIDS education programme for secondary school students in Nigeria: a review of effectiveness.
Nigerian secondary school students are becoming sexually active at an increasing earlier age. Sexually active students are at risk of contacting STDs, including HIV infection. As a result, health education initiatives to increase level of knowledge, influence attitudes and encourage safe sexual practices are being implemented in schools, but the effectiveness of these programmes have not been evaluated. ⋯ After the intervention, the mean number of reported sexual partners among the experimental students significantly decreased from 1.51 to 1.06, while it increased from 1.3 to 1.39 among the controls. Among the intervention students there was also an increase in consistent use of the condom and the use of the condom at last sexual intercourse. We conclude that students can benefit from specific education programmes that transmit important information necessary to prevent risky behavior, and improve knowledge and attitudes on HIV/AIDS.

AIDS knowledge, condom attitudes, and sexual behavior were examined in a sample of 193 substance-abusing juvenile offenders on probation or parole. The majority of these youths reported being sexually active, and many admitted to early onset of sexual activity as well as unsafe sexual practices. ⋯ General attitudes toward condoms and the reported use of a condom at first sexual intercourse experience were the only statistically significant predictors of subsequent condom use. The relevance of these findings to the development of AIDS prevention programs for juvenile offenders is discussed.
