Acral melanoma (AM) is a rare subtype of cutaneous melanoma (CM) that disproportionately affects skin of colour and carries a poorer prognosis than other melanoma subtypes. The poor prognosis is attributed to late diagnosis and subsequent relatively high Breslow thickness, but also to an intrinsic biological aggressiveness. Scientific data on AM from the developing world are limited and a need exists to characterise the disease further in the South African (SA) population. ⋯ AMs accounted for a significant proportion of all CMs diagnosed. Patients presented with an advanced stage of disease at diagnosis, and further studies are needed to further investigate the reasons for delayed diagnosis.

Twelve years after cardiologists and cardiac surgeons from all over the world issued the 'Drakensberg Declaration on the Control of Rheumatic Fever and Rheumatic Heart Disease in Africa', calling on the world community to address the prevention and treatment of rheumatic heart disease (RHD) through improving living conditions, to develop pilot programmes at selected sites for control of rheumatic fever and RHD, and to periodically review progress made and challenges that remain, RHD still accounts for a major proportion of cardiovascular diseases in children and young adults in low- and middle-income countries, where more than 80% of the world population live. Globally equal in prevalence to human immunodeficiency virus infection, RHD affects 33 million people worldwide. ⋯ At the present time, the only effective treatment for symptomatic RHD is open heart surgery, yet that life-saving cardiac surgery is woefully absent in many endemic regions. In this declaration, we propose a framework structure to create a co-ordinated and transparent international alliance to address this inequality.

Hypertension is common, affecting over one billion people worldwide. In sub-Saharan Africa, hypertensive disease not only affects the older population but is becoming increasingly prevalent in younger individuals. In South Africa (SA), >30% of the adult population has hypertension, making it the single most common cardiovascular risk factor and the predominant contributor to cardiovascular disease and mortality. Elevated blood pressure is the most common perioperative comorbidity encountered in non-cardiac surgical patients, with an overall prevalence of 20 - 25%, and it remains poorly controlled in low- and middle-income countries. Hypertension in the perioperative setting may adversely affect patient outcome. It therefore not only flags possible perioperative challenges to anaesthesiologists, but also identifies patients at risk of long-term morbidity and mortality. ⋯ The perioperative period may be an important opportunity to identify undiagnosed hypertensive patients. The perioperative encounter may have a significant public health implication in facilitating appropriate referral and treatment of patients with hypertension to decrease long-term cardiovascular complications in SA.

Recently, there have been significant advances in the battle against tobacco use in Africa, with achievements including ratification of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC) and the passing of tobacco control legislation in several countries. Many African countries have achieved measured success, while Uganda, South Africa and Mauritius have accomplished significantly more in their efforts to curb tobacco use. Nevertheless, few African countries meet the standards of the individual WHO FCTC articles with regard to comprehensive implementation. ⋯ Technical support, capacity building and adequate financing are needed in Africa to enable countries to competently manage legal challenges to tobacco control and deal with the subversive tactics of the industry. Civil society and the media - major players in holding governments accountable for responsible stewardship - need to educate and pressurise African politicians and governments to implement and enforce effective tobacco control policies. Otherwise, if unchecked, the widespread uptake of tobacco use will be a threat not only to health but also to sustainable human development in Africa.
