A comparison of chest radiographic findings in human immunodeficiency virus-positive and -negative children with pulmonary tuberculosis.

Aim: To compare chest radiography (CXR) findings in human immunodeficiency virus (HIV)-positive and HIV-negative children who had microbiologically confirmed pulmonary tuberculosis (PTB).

Materials And Methods: Retrospective analysis of CXRs from children with known HIV status and microbiologically confirmed PTB (culture or GeneXpert Xpert MTB/RIF positive), who were hospitalised or seen at a primary healthcare centre over a 5-year period. Radiological findings were compared according to HIV and nutritional status.

Accuracy of CT angiography for detecting ruptured intracranial aneurysms.

Background: Digital subtraction angiography (DSA) is invasive, costly and unavailable in many South African hospitals; however, it remains the gold standard for imaging intracranial aneurysms. CT angiography (CTA) is a non-invasive and readily available screening tool prior to DSA.

Objectives: This study aimed to evaluate the diagnostic performance of CTA in detecting ruptured intracranial aneurysms using DSA as the reference standard and to determine the effect of aneurysm size and location on CTA sensitivity.

Sellar spine: A rare Bony variant of the Sella Turcica.

A sellar spine is a rare osseous projection from the dorsum sellae, resulting in variable compression of sellar and suprasellar structures and varied clinical presentations. CT is the diagnostic modality of choice, while variable signal intensity on MRI may mimic a pituitary microadenoma. A patient presented with hypoprolactinaemia and puerperal alactogenesis due to a sellar spine diagnosed on CT Brain.

A retrospective 5-year review of rubella in South Africa prior to the introduction of a rubella-containing vaccine.

South Africa has yet to introduce a rubella-containing vaccine (RCV) into its Expanded Programme on Immunisation (EPI). Here we evaluated the incidence of laboratory-confirmed rubella and congenital rubella syndrome (CRS) cases over the years 2015 to 2019, to document the epidemiology of rubella and CRS within South Africa prior to a RCV introduction. This retrospective study evaluated the number of laboratory-confirmed rubella cases reported through the national febrile rash surveillance system.

Perceived HIV-related stigma among university students in South Africa: implications for HIV testing.

HIV-related stigma, and particularly perceived stigma, has a negative impact across the HIV care continuum. This study adds to our understanding of stigma by assessing how perceived stigma varies from one context to another and how such differences are associated with the location where individuals would prefer an HIV test. We used self-administered questionnaire data (n = 378) obtained from a convenience sample of students (18 years and older) attending a tertiary education institution in Durban, South Africa.
