Genital ulcer disease in women infected with human immunodeficiency virus.

OBJECTIVE: The purpose of this study was to determine the prevalence and microbiologic characteristics of genital ulcer disease in a population of human immunodeficiency virus-infected women. STUDY DESIGN: A retrospective cohort study was performed in university-affiliated, hospital-based women's human immunodeficiency virus clinics. A total of 307 women with human immunodeficiency virus infection were followed up during 20 months. There were no interventions. Age, race, CD4+ cell counts, bacteriologic and virologic analyses in cases of ulcers, serologic testing for syphilis, and histopathologic examination in selected cases (n = 6). RESULTS: Among 307 women followed up over a 20-month period, 43 ulcers were detected with a prevalence of 14%. Among the ulcer cases the average absolute CD4+ lymphocyte number was 210/mm3. Diagnostic evaluation yielded no proven etiologic agent in 26 (60%) of the cases. Twelve of the 43 cases (28%) were positive for herpes simplex-2. Five cases (12%) yielded unusual or mixed bacteriologic types. No cases were attributable to primary syphilis infection. One case each of an ulcer infected with cytomegalovirus, Chlamydia trachomatis, and Gardnerella vaginalis, as well as three unusual presentations of herpetic ulcers, is analyzed in detail. CONCLUSION: These cases exemplify the often dramatic presentation of human immunodeficiency virus-related genital ulcers and the clinical complexity of both diagnosis and management. The frequent lack of an infectious or neoplastic cause in human immunodeficiency virus-infected women with genital ulcer disease suggests that human immunodeficiency virus may play a local role in causation or exacerbation. Biopsies of atypical genital ulcers should be considered to aid diagnosis. Further studies are needed to elucidate the pathogenesis of genital ulcer disease in human immunodeficiency virus-infected women.

The economic value of contraception: a comparison of 15 methods.

OBJECTIVES: The purpose of the study was to determine the clinical and economic impact of alternative contraceptive methods. METHODS: Direct medical costs (method use, side effects, and unintended pregnancies) associated with 15 contraceptive methods were modeled from the perspectives of a private payer and a publicly funded program. Cost data were drawn from a national claims database and MediCal. The main outcome measures included 1-year and 5-year costs and number of pregnancies avoided compared with use of no contraceptive method. RESULTS: All 15 contraceptives were more effective and less costly than no method. Over 5 years, the copper-T IUD, vasectomy, the contraceptive implant, and the injectable contraceptive were the most cost-effective, saving $14,122, $13,899, $13,813, and $13,373, respectively, and preventing approximately the same number of pregnancies (4.2) per person. Because of their high failure rates, barrier methods, spermicides, withdrawal, and periodic abstinence were costly but still saved from $8933 to $12,239 over 5 years. Oral contraceptives fell between these groups, costing $1784 over 5 years, saving $12,879, and preventing 4.1 pregnancies. CONCLUSIONS: Contraceptives save health care resources by preventing unintended pregnancies. Up-front acquisition costs are inaccurate predictors of the total economic costs of competing contraceptive methods.

Traditional birth attendants and maternal mortality in Ghana.

Maternal mortality is high in most African countries, particularly in rural areas where access to formal health care is limited. The sociopolitical and economic environment complicates the medical factors directly responsible for this high rate. Since the 1970s many African countries have addressed this problem by training traditional birth attendants (TBAs) in health promotion and in the basics of safe delivery and referral. The Danfa Rural Health Project in Ghana has trained and supervised TBAs since 1973. It is located relatively close to the health services of the capital city of Accra, providing an ideal environment for the practice of trained TBAs. Thirty-seven trained TBAs currently practice in the area. Most provide patient education and encourage women to go to the health center for preventive services. However, many report routinely performing the high risk deliveries that they have been taught to refer to higher level care and that when they do refer, their patients may not go. Reasons for referral refusal frequently cited by TBAs include financial limitation or lack of transportation and the patients fear of disrespectful or painful treatment from medical personnel. In the rural environment, the trained TBA's greatest contribution to lower maternal mortality rates may lie in the area of health promotion rather than disease intervention.

Maternity shelter care for adolescents: its effect on incidence of low birth weight.

A group of 112 pregnant adolescents residing in a maternity shelter was compared with a group of 113 pregnant adolescents residing in their own homes but receiving identical medical care. The sheltered group was made up of a particularly high-risk group: they were more likely to be black, unmarried, receiving public assistance, and registered later for prenatal care than the group living at home. Despite these differences, the sheltered group delivered significantly fewer infants of low birth weight and preterm gestation than the control group. Variables assessed in this study fail to explain this difference. It is concluded that the services offered in a maternity shelter can have a positive impact on the reduction of low birth weight deliveries in a group of high-risk patients. These results indicate that the social and behavioral correlates of low birth weight remain to be fully defined and understood.
