| fetal alcohol syndrome--south africa, 2001. | fetal alcohol syndrome (fas) is caused by maternal alcohol use during pregnancy and is one of the leading causes of preventable birth defects and developmental disabilities. the fas phenotype is characterized by a combination of facial dysmorphic features, growth retardation, and central nervous system (cns) abnormalities. state-based estimates of the prevalence of fas in the united states vary from 0.3 to 1.5 per 1,000 live-born infants. recently, the highest prevalence of fas worldwide was rep ... | 2003 | 12869904 |
| symptomatic relapse of hiv-associated cryptococcal meningitis after initial fluconazole monotherapy: the role of fluconazole resistance and immune reconstitution. | cryptococcal meningitis (cm) in south africa is often treated with fluconazole as initial therapy. surveillance data suggest that the prevalence of fluconazole-resistant cm is increasing, and expanding access to antiretroviral therapy is resulting in increasing recognition of immune reconstitution inflammatory syndrome. therefore, we conducted a study to assess the contribution of these factors to cm relapse in this context. | 2006 | 16983622 |

| molecular characterization of non-subtype c and recombinant hiv-1 viruses from cape town, south africa. | hiv was first diagnosed within south africa in 1982. homosexual transmission of hiv-1 dominated the epidemic within the country in the early stages of the 1980s. currently heterosexual transmission of hiv-1 is responsible for the majority of hiv cases in south africa with subtype c hiv-1 being responsible for an estimated 95% of infections. only a few papers have been published on non-subtype c hiv-1 detection within south africa. this study characterized subgenomic and near full-length sequence ... | 2009 | 19446657 |
| emergence and diversity of different hiv-1 subtypes in south africa, 2000-2001. | hiv-1 is a major health problem in south africa with an average prevalence rate of 29.1% in pregnant women and between 4.9 and 6.1 million people infected. using env gp120 v3 serotyping and genotyping techniques 410 patient samples were investigated. most of the samples were obtained from different clinics in the greater cape town area of the western cape province in south africa. these included an academic hospital, state and private clinics, an informal settlement, sex worker cohorts, and the ... | 2009 | 19774685 |
