The clinical features of tropical phlebitis are descriptionbed and a case in which both external jugular veins were thrombosed with the production of marked oedema of the eyes and face, resembling nephritis, is recorded. Lumbar sympathetic block is a useful form of treatment in tropical phlebitis affecting the femoral vein in its early stages when there is fever and much swelling. Its execution is easy. The arterial spasm in this disorder may indicate the simultaneous occurrence of an arteritis and may perhaps account for the occasional case of unexplained gangrene in an extremity or extremities, found in the African.
The information to be derived from the above analysis may be summarized as follows: the imperative need for the systematic Rh testing of all females, especially during the ante-natal period, is once more amply demonstrated. Rhesus factor incompatibility is unimportant as an aetiological factor in repeated abortions during the early months of pregnancy. A proportion of the foetal deaths and deaths at term can be avoided if steps are taken to diagnose sensitization of the mother during pregnancy. Such information also permits prompt treatment of affected babies with a corresponding improvement in prognosis. The danger of transfusing females of unknown Rh status is illustrated and emphasized. Of 59 affected babies, 16 survived without transfusion; 35 were transfused with Rh negative blood and25 of these babies survived. The recovery rate of 70% compares very favourably with figures published overseas and further improvement is to be anticipated.
