Incorrect condom use and frequent breakage among female sex workers and their clients.

Our objective was to assess if female sex workers (FSWs) and their potential male clients in Cotonou, Benin, know how to use male condoms correctly. From April to June 2000, 314 FSWs and 208 men were interviewed, and asked to demonstrate on a wooden penis how they usually use male condoms. In all, 27.

Sexually transmitted infections in male clients of female sex workers in Benin: risk factors and reassessment of the leucocyte esterase dipstick for screening of urethral infections.

Objectives: (1) To assess risk factors for urethral infections with Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis among male clients of female sex workers (FSWs) in Benin; (2) to study the validity of LED testing of male urine samples compared to a highly sensitive gold standard (PCR) for the diagnosis of urethral infections with the organisms cited above.

Methods: Male clients of FSWs (n=404) were recruited on site at prostitution venues in Cotonou, Benin, between 28 May and 18 August 1998. A urine sample was obtained from each participant just before he visited the FSW, and tested immediately using a leucocyte esterase dipstick (LED) test.

Effectiveness of COL-1492, a nonoxynol-9 vaginal gel, on HIV-1 transmission in female sex workers: a randomised controlled trial.

Background: Nonoxynol-9 (rINN, nonoxinol-9) is an over-the-counter spermicide that has in-vitro anti-HIV-1 activity. Results of studies of its effectiveness in prevention of HIV-1 infection in women have been inconclusive. We aimed to assess effectiveness of this vaginal gel.

Role of core and bridging groups in the transmission dynamics of HIV and STIs in Cotonou, Benin, West Africa.

The potential for exposure of low and high risk women to HIV and sexually transmitted infections (STI) through unprotected sex with male clients of female sex workers in Cotonou could account for most if not all of the estimated yearly numbers of HIV infections in Cotonou women (approximately 1000). As ongoing transmission of HIV, and also of the most predominant STIs such as gonorrhoea and HSV-2, appears to be largely fuelled by transmission within core and bridging groups in Cotonou, interventions targeted at both female sex workers and their male clients remain of the utmost importance and could have a significant effect on the evolution of HIV/STI epidemics in Benin.

Syndromic versus laboratory-based diagnosis of cervical infections among female sex workers in Benin: implications of nonattendance for return visits.

Background: The syndromic diagnostic approach is the most realistic and cost-effective strategy for controlling sexually transmitted infections (STIs) in the developing world. Its potential advantages should be evaluated.

Goal: The goal of the current study was to examine whether the syndromic approach might diagnose more cases of cervicitis due to Neisseria gonorrhoeae or Chlamydia trachomatis than laboratory tests.
