Sexually transmitted diseases
-
The Internet is increasingly used for the recruitment of sex partners, potentially leading to increased risks for sexually transmitted infections (STIs). Less is known about the use of the Internet as a resource for STI education and prevention. ⋯ Among STI clinic clients in Denver, nearly half have access to the Internet. Sex-seeking appears to be most prevalent among MSM. Internet use for STI information is common among those with Internet access and even more widespread among those who access the Internet to seek sex. Research is needed to develop and evaluate Internet-based STI-prevention interventions.

Self-collected samples have been shown to be an acceptable and sensitive method for the detection by polymerase chain reaction (PCR) of sexually transmitted infections (STIs) among women. GOAL The goal of the study was to compare self-collected sampling methods to conventional practitioner endocervical sampling for the PCR detection of Chlamydia trachomatis and Neisseria gonorrhoeae to compare two self-collected sampling methods for the detection of T vaginalis by PCR. ⋯ Self-collected specimens offer women in remote communities an acceptable and sensitive alternative method of testing for STIs. The low sensitivity of N gonorrhoeae PCR of urine specimens may reflect poor transport and storage conditions, which we have shown can be improved by freezing urine specimens and reducing transport delays.

In the Netherlands 73% of cases of neonatal herpes are caused by herpes simplex virus type 1 (HSV-1), whereas in the United States a majority are caused by HSV type 2 (HSV-2). GOAL To understand this difference we undertook a seroepidemiological study on the prevalence of HSV-1 and HSV-2 among pregnant women. ⋯ The seroprevalence of HSV-1 and HSV-2 antibodies among pregnant women in the Netherlands shows significant geographical differences, which were attributed to ethnical variation. However, the epidemiologic differences did not correlate with the incidence of neonatal herpes in the Netherlands.

Adolescents are at high risk of sexually transmitted disease (STD)/HIV infection, and one vulnerable subgroup is African American females. The association between adolescents' previous experience of STD and recent sexual risk behaviors has been ill-defined. ⋯ Among this sample of female adolescents, past STD diagnosis was an indicator of current high-risk sexual activity and increased risk for two common STDs: gonorrhea and trichomoniasis. Although adolescents may gain factual knowledge from the experience of having an STD diagnosed, they are not applying that knowledge to their current sexual behaviors. Thus, these adolescents remain at risk for subsequent STD infection. Therefore, the findings suggest that there is a need to intensify clinic-based prevention efforts directed toward adolescents with a history of STDs, as a strategy for reducing STD-associated risk behaviors and, consequently, the likelihood of new STD infections.

Randomized Controlled Trial Comparative Study Clinical Trial
A randomized, comparative pilot study of azithromycin versus benzathine penicillin G for treatment of early syphilis.
Penicillin is the only medication currently recommended for treatment of early syphilis in non-penicillin-allergic patients. Preliminary data suggest that azithromycin may be effective for syphilis therapy. ⋯ Oral therapy with 2.0 g of azithromycin as a single dose or as two doses 1 week apart is a promising alternative to therapy with benzathine penicillin G for syphilis and should be studied further.
