Long-term use of the female condom among couples at high risk of human immunodeficiency virus infection in Zambia.

Background: Few studies have measured female condom use for more than a 6-month period or among persons at high risk of STD.

Objective: To measure long-term use of the female condom among couples at high risk of HIV infection and to evaluate the effect of female condom use on unprotected coital acts.

Study Design: Ninety-nine Zambian couples with symptomatic sexually transmitted diseases (STD) received female condoms, male condoms, and spermicides and were counseled to use either condom plus spermicide for each coital act.

Sexually transmitted disease among married Zambian women: the role of male and female sexual behaviour in prevention and management.

Objectives: Few studies have evaluated the relation between male and female sexual behaviour and STD among married African women. The objectives of this study were to identify male and female sexual behaviour associated with female STD, and to explore whether incorporating male and female sexual behaviour and male symptoms can improve algorithms for STD management in married African women.

Methods: 99 married couples with one symptomatic member (58 males, 41 females) attending an STD clinic in Lusaka, Zambia were interviewed separately about sexual and contraceptive behaviour, and had physical examinations.

Monoclonal origin of multicentric Kaposi's sarcoma lesions.

Background: Kaposi's sarcoma has features of both hyperplastic proliferation and neoplastic growth. Multiple lesions, in which spindle cells are prominent, often arise synchronously over widely dispersed areas. We tested the hypothesis that the spindle cells in these multicentric lesions originate from a single clone of precursor cells.

Monoclonal antibodies against Haemophilus ducreyi lipooligosaccharide and their diagnostic usefulness.

Monoclonal antibodies against the lipooligosaccharide of Haemophilus ducreyi were produced. Two of them, MAHD6 and MAHD7, were found to be relatively, although not absolutely, specific and reacted with nearly all strains of Haemophilus ducreyi tested: 59 of 60 and 60 of 60, respectively. The diagnostic usefulness of MAHD7 was assessed.
