The clinicopathological landscape of thyroid cancer in South Africa-A multi-institutional review.

Background: In South Africa (SA), data on the incidence of thyroid cancer is limited. Papillary thyroid carcinoma is by far the most common malignancy in developed countries; however, a preponderance of follicular thyroid cancer in developing countries, despite iodized salt, has been observed. The aim of this study was to describe the national landscape of thyroid cancer in SA with reference to pathological subtypes, surgical outcomes, and treatments offered.

Adrenal Incidentaloma Controversial Size Recommendations.

The size of adrenal incidentalomas has important implications for diagnosis and management. Recommendations from endocrine societies do not all correlate with regard to adrenal incidentaloma size. Therefore, the aim was to compare adrenal incidentaloma size recommendations between different endocrine societies and the reasoning for these recommendations.

The impact of colon injuries on the outcome of gunshot wounds to the abdomen.

Purpose: Factors predicting morbidity and mortality in patients with colon-related gunshot injuries and the management of these injuries are not always straightforward. This aimed to assess the impact of abdominal gunshot wounds with colonic injuries on patients' overall outcomes.

Methods: This cross-sectional prospective observational study compared patients with colon injuries and without colon injuries.

Association between pheochromocytoma and neurofibromatosis type I: a rare entity in the African population.

The association of pheochromocytoma in patients with neurofibromatosis type I has rarely been reported in low-income countries, especially on the African continent. A 43-year-old woman with neurofibromatosis type I was diagnosed with a right adrenal pheochromocytoma in Pretoria, South Africa. To our knowledge, this report is the first case to be published of a patient with neurofibromatosis type I diagnosed with a pheochromocytoma in Pretoria, and one of three cases on the African continent.

Comparison of pathological clotting using haematological, functional and morphological investigations in HIV-positive and HIV-negative patients with deep vein thrombosis.

Background: Patients infected with the human immunodeficiency virus (HIV) are more prone to systemic inflammation and pathological clotting, and many may develop deep vein thrombosis (DVT) as a result of this dysregulated inflammatory profile. Coagulation tests are not routinely performed unless there is a specific reason.

Methods: We recruited ten healthy control subjects, 35 HIV negative patients with deep vein thrombosis (HIV negative-DVT), and 13 HIV patients with DVT (HIV positive-DVT) on the primary antiretroviral therapy (ARV) regimen-emtricitabine, tenofovir and efavirenz.

Pathological Clotting and Deep Vein Thrombosis in Patients with HIV.

The number of people infected with human immunodeficiency virus (HIV) is rapidly increasing and the majority of those infected are living in sub-Saharan Africa. Some hallmarks of HIV are inflammation and upregulation of inflammatory markers. A pathological coagulation system may accompany these inflammatory changes and potentially result in venous thromboembolism such as a deep vein thrombosis (DVT).

Controversy regarding when clinically suspicious thyroid nodules should be subjected to surgery: Review of current guidelines.

Background: The work-up of a thyroid nodule to diagnose malignancy is not always straightforward. There are various international thyroid societies each with their own guidelines on the approach to a thyroid nodule. The aim is therefore to determine whether a clinically suspicious thyroid nodule should be subjected to surgery.
