BACKGROUND Mortality in the first months of antiretroviral therapy (ART) is a significant clinical problem in sub-Saharan Africa. To date, no post-mortem study has investigated the causes of mortality in these patients. METHODS HIV-positive adults who died as in-patients at a Johannesburg academic hospital underwent chart-review and ultrasound-guided(More)
Interactions between HIV and surgical diseases are relatively poorly described in high HIV prevalence settings. We report HIV prevalence and its associations in a prospective study of adults admitted to surgical units in Soweto, South Africa. Voluntary counselling and testing (VCT) for HIV was offered to surgical inpatients. Research nurses interviewed(More)
OBJECTIVE To ascertain the immediate and underlying causes of death in adults who died in hospital with a premortem diagnosis of tuberculosis. DESIGN Causes of death were assessed independently by internists and pathologists in 50 adults admitted to two Soweto hospitals who died 24 h or more after admission. Detailed record reviews and complete autopsies,(More)
OBJECTIVE To ascertain progression and regression of cervical dysplasia in HIV-infected women in Soweto. DESIGN Prospective cohort. METHODS Women attending an HIV wellness clinic were offered cervical smears as part of care; smears were assessed using the Bethesda system. Those with high-grade lesions or worse were referred for colposcopy. Progression(More)
BACKGROUND HIV-infected women are at increased risk for developing cervical cancer. Women living in resource-limited countries are especially at risk due to poor access to cervical cancer screening and treatment. We evaluated three cervical cancer screening methods to detect cervical intraepithelial neoplasia grade 2 and above (CIN 2+) in HIV-infected women(More)
OBJECTIVE To determine the impact of HAART on incidence, regression, and progression of cytopathological abnormalities in HIV-infected women. DESIGN Prospective cohort. METHODS HIV-infected women (N=1123) from Soweto, South Africa underwent serial cervical smears that were analyzed and reported using the Bethesda System. The results of HAART and(More)
BACKGROUND One of the constraints of the conventional FNA smear is the limited material available for adjuvant diagnostic investigations including immunocytochemistry. The cell block technique employs the retrieval of small tissue fragments from a FNA specimen which are processed to form a paraffin block. It is widely accepted that cell block technique(More)
OBJECTIVES To describe the bone marrow lesions in eight cases of Cryptococcus neoformans infection involving the bone marrow in HIV-infected patients. METHODS Archival bone marrow biopsies from patients with HIV-related cryptococcosis of the bone marrow were retrospectively reviewed. Cryptocococcal organisms were identified on haematoxylin- and(More)
We retrospectively reviewed a consecutive case series of 257 adults with HIV infection who had undergone a bone-marrow examination with trephine bone biopsy, to assess the diagnostic usefulness of bone-marrow examination and evaluate possible predictors of a diagnostic examination. Bone-marrow examination was positive in 97 (38%) patients and gave a unique(More)
Xpert MTB/RIF (Xpert) is recommended for human immunodeficiency virus (HIV)-associated pulmonary tuberculosis but not extrapulmonary tuberculosis. We assessed the performance of Xpert for HIV-associated lymph node tuberculosis (LNTB), the most common type of extrapulmonary tuberculosis. Among HIV-infected adults suspected of LNTB presenting for fine needle(More)
