    Informing curriculum development in health sciences
    (AFRICAN SUN MeDIA, 2011) Stefan, Cristina
    INTRODUCTION: The education of future medical professionals has to ensure that their knowledge and skills are relevant to the health care needs of their future patients, in a context of continuous change of society, science, technology and environment. A rapid tour of the horizon will identify a few examples of evolving health care needs, which should inform the curricula of medical schools. To start with, the disease profile of populations evolves as their income and lifestyle change and their life expectancy increases. Another example would be the latest pandemic of HIV/AIDS, which requires appropriate medical skills and a rethinking of the management of many diseases for those living with the virus. Further, patients’ increasing awareness of their rights has to be paralleled by doctors’ awareness of the complex ethical issues which sometimes arise from the practice of the profession. In addition, the progress of science opens new knowledge domains, such as genomics – the study of the structure and function of genes – which reshape the understanding of disease. The accumulation of data from extensive research in all fields of medicine makes it possible, for the first time in the history of the profession, to practise evidence-based medicine, informed by the systematic analysis of the results of numerous studies on the same disease and thus to move away from treatments based merely on case series or expert opinions. A further example, by no means the last, is the renewed interest in complementary and alternative medicine in the search to expand the therapeutic panoply against disease.

    Kaposi sarcoma in South African children
    (BioMed Central, 2010-10) Stefan, Cristina; Stones, David; Wainwright, Linda; Newton, Rob
    The AIDS epidemic has contributed to an abrupt increase of the incidence of Kaposi sarcoma, especially in Sub-Saharan Africa, to values tens of times higher than in the pre-epidemic era. There is, however, very little literature concerning the clinical features of this disease and its management and outcome in HIV-positive children in Africa.
