    Postgraduate Diploma in Occupational Health (DOH) - Modules 1 and 2
    (2014-09-19) Myers, Jonny
    Designed to help teach doctors currently practising occupational health. First two modules of a two year part-time flexible distance learning course aimed primarily at medical doctors currently practising occupational health. It includes a residential block release component which consists of between 3 or 4 weeks over the two year cycle for practicum. There will be substantial requirements for homework in the form of assignments and project related work, expected self-directed learning and distance communication between students and teachers extending over the two years. While the course is aimed primarily at medical doctors currently practicing occupational health, it is also suited to selected graduates with appropriate University qualifications in relevant health sciences, as long as these individuals are currently practicing professionally in an occupational health setting. There are 8 modules (the two included here cover Occupational Hygiene and Epidemiology & Biostatistics). Each module has a theme around which the inputs are organised. Teaching inputs are intended to be non-didactic, and to allow student participation wherever possible. Candidates are expected to undertake substantial homework preparation and activities as well as self-directed learning. They will be expected to read widely and intensively around topics, and to provide teaching inputs themselves either directly or by way of specially structured interactive debates and role-play simulations. The content of these activities will include critical appraisal of the occupational health literature, project work, presentations by students as well as epidemiological, bio statistical, toxicological and occupational clinical assignments.

    The prevalence of childhood asthma in white primary schoolchildren in the southern suburbs of Cape Town
    (1993) Nagel, Frederick Otto
    The author participated in an international survey organised by the British Medical Research Council (MRC) epidemiological unit in Cardiff, Wales which set out to compare the prevalence of asthma in several countries. The motivation for participating in this study was that very little previous prevalence data for asthma is available for coloured or white children in South Africa. A protocol designed by the British MRC Epidaemiology Unit was followed. One thousand one hundred and seventy four white children aged 12 years attending a random selection of primary schools in the Southern Suburbs of Cape Town were studied. A standard MRC questionnaire on asthma was completed by parents. The subjects then underwent an exercise challenge test (ECT) which involved running on the level for six minutes. During the ECT, we measured the forced expiratory volume in 1 second (FEVl) before and after the exercise. A fall in post exercise FEVl of 15% or greater was regarded as evidence of bronchoconstriction and considered diagnostic of asthma. This method is thought to identify 70-90% of asthmatics (Anderson 1985, Lee et al 1989, Pierson 1988). Using this criterion, 52 (4.4%) of the children had asthma. The prevalence of 4.4% in this study is higher than 3.1% reported in a previous study of black children in Guguletu (Van Niekerk et al, Clinical Allergy 1979). However, the age spectrum of children was different in that study. Terblanche et al (1990) report the prevalence of exercise induced bronchoconstriction (EIB) in white and coloured children to be 5.87% and 4.05% respectively. The level of FEVl reduction for a diagnosis of EIB approved for this study was lower than usually accepted. Using conventional criteria for a diagnosis of EIB, Burr et al (1989) reported a prevalence of 7.7% in Cardiff, Wales. This study confirms that exercise induced asthma is a common problem in 12-year old white children in Cape Town.
