Pneumonia and diarrhoeas are an important cause of toddler mortality and morbidity in developing countries. Of the 147 children admitted to the University Hospital at Kuala Lumpur in 1971 for pneumonia and diarrhoeas 50 (34%) were found to be suffering from protein-calorie malnutrition of varying degrees of severity. The malnourished children tended to come from poorer homes, and to have a larger number of siblings born in rapid succession when compared with normal weight children. Anemia was more common among the malnourished children. The interaction of infection and malnutrition and the social implications of these diseases are important. It is vital that hospitals in developing countries promote health in addition to their traditional curative role.
Among a series of 101 patients bitten by sea-snakes in Malaya in the years 1957-64, 80% were fishermen. Bathers and divers are occasionally bitten. Before sea-snake antivenom became available the mortality-rate (despite the high toxicity of sea-snake venom) was only 10%; however, of 11 with serious poisoning, 6 died. Subsequently 10 patients with serious poisoning received specific sea-snake antivenom; 2 patients, admitted moribund, temporarily improved but died, and 8 patients recovered dramatically. In serious poisoning the suitable dosage of intravenous sea-snake antivenom is 3000-10,000 units; in mild poisoning 1000-2000 units should suffice.
