The effects of barrier and spermicidal methods of contraception on cervical cancer risk were examined by studying 479 cases of histologically confirmed invasive cervical cancer cases and 788 random digit dialing controls. In addition to a detailed history of contraceptive practices, information was available on numerous potential confounders, including demographic characteristics, sexual behavior, reproductive factors, Pap smear screening history, and smoking. ⋯ Effects were only seen among subjects of higher income and education levels, suggesting that patterns of usage may be important. The potential ability of spermicides to reduce cervical cancer risk by neutralizing viral agents warrants further attention.

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.

Towards developing a diagnostic algorithm for Chlamydia trachomatis and Neisseria gonorrhoeae cervicitis in pregnancy.
C trachomatis and N gonorrhoeae are major causes of maternal and neonatal morbidity and mortality in developing countries. To identify characteristics predictive of cervical infection, we examined pregnant women attending an antenatal clinic in Nairobi, Kenya. ⋯ A screening programme for cervical infection which tested women with one or both risk markers would have a sensitivity of 68% (95% CI 51 to 85%) and a positive predictive value of 0.35 (95% CI 0.22 to 0.47). In countries where resources are limited, diagnostic algorithms incorporating clinical signs and behavioural characteristics may be useful in identifying pregnant women at high risk of cervical infection.
