Despite the proven value of an adequate occupational health service, South Africa, with some exceptions, has lagged behind. Our rapidly developing industries with their own special problems merit closer attention. The inadequacy of the present services is outlined and mention is made of how Great Britain is tackling the problem. The scope of a satisfactory occupational health service for this country is tabulated, and it is suggested how employer-provided services could be extended to cover the individual preventive, curative and rehabilitative aspects of the subject.
Twenty-two cases of hypertension were treated with thyroid extract following a control period of placebo administration. Two out of 18 patients had a decrease in diastolic pressure of more than 15 mm. Hg on no treatment or on placebo therapy, while in 2 out of 25 trials there was a decrease in diastolic pressure of more than 15 mm. Hg on thyroid therapy. It does not appear that thyroid extract in the dose used has any dramatic effect beneficial or otherwise on the level of blood pressure or on the symptoms of essential hypertension.
