Beta-adrenergic receptor blocker (BARB) drugs are a wide range of medicines that are used in various conditions, including chronic heart failure (HF). Several studies have reported a wide-ranging inappropriate use of evidence-based beta-blockers (EBBBs) in chronic HF in both inpatients and outpatients. ⋯ This study showed that 95.0% of chronic HF patients were utilising EBBBs, and none received the optimal dose as recommended in the guidelines. Pharmacotherapy with EBBBs should be optimised among patients with chronic HfrEF, as these drugs reduce both morbidity and mortality.

Angioedema is the most common acute allergic presentation to emergency centres (EC), with hospitalisation rates increasing in high-income countries. Angioedema can complicate with life-threatening laryngeal obstruction. There are no local data; therefore, we aimed to characterise acute angioedema cases presenting to ECs and develop a simple management algorithm. ⋯ Angioedema is the most common allergy presentation to two ECs in Cape Town, SA. Bradykinin-mediated angioedema secondary to ACE-I therapy is the single most common offender, and was not appropriately managed in more than a third of cases. Based on these findings, we have developed a management algorithm that easily stratifies patients into bradykinin or mast cell-mediated angioedema with a step-by-step management approach that is applicable to the SA context. Ongoing awareness and education on allergy emergencies are required to ensure accurate diagnosis of less common causes of angioedema (particularly bradykinin-mediated angioedema) and linkage to allergy specialist care.

Cavernous sinus thrombosis is a rare life-threatening complication of herpes zoster ophthalmicus (HZO). This case highlights the importance of at least considering the diagnosis in all cases of HZO, as the consequences of missing it can be disastrous.

Medical practitioners in South Africa manage a quadruple burden of disease. Junior doctors, who contribute significantly to the health workforce, must complete 2 years of internship training and 1 year of community service work in state health facilities after graduation to register as an independent medical practitioner. The aim of this article is to give a critical appraisal of the current national internship programme and why it was implemented, and outline suggestions for future changes. There is a compelling need to train competent, confident doctors while ensuring that the requirements and demands of our health system remain a central concern.

Observational Study
The association between cytology and histopathology in thyroid nodules over a 6-year period in an urban hospital in South Africa.
Thyroid cancer is prevalent both internationally and locally, and is the most common cause of endocrine malignancies in Africa. The prognosis of thyroid cancer in general is quite good, but to achieve good outcomes, appropriate methods for diagnosis are important. A cytology result obtained from a fine needle aspiration and biopsy (FNAB) is one such method, and is less invasive and has less risk compared with obtaining a histological result via open surgery. However, there are accuracy differences that have been reported in different literature findings. ⋯ There was good correlation between cytology and histology for thyroid nodules. Differences were noted between the percentage of malignant cases in the different Bethesda categories compared with international standards as noted above. We recommend that further studies are conducted locally to improve knowledge on this topic.
