Archives Of Internal Medicine Volume 11 Scholars Choice Edition PDF Download

Excerpt from The Archives of Internal Medicine, 1913, Vol. 11 When we consider the medical history of Panama with reference to the origin of its population, the negroes from Africa and possibly the Pacific Islands, Chinese, introduced by the French Canal Company; Coolies, Sikhs and Bengalis from India, besides those representatives of the Caucasian race who have come from every portion of the tropical and subtropical world, Americans from the Philippines, various globe-trotters and tropical tramps, we naturally expect to encounter here some of the diseases especially characteristic of other lands, and we are not surprised to find that echinococcus infections are confined strictly to Spanish laborers. Infection by Taem'a mum and T. Saginata occurs among Europeans and Americans. Bilharziosis comes almost exclusively from the French West India Islands, Filaria demarquai in negroes from St. Vincent, Old World hookworms, A. Duodenale, among the West Indians, possibly introduced there by coolies. Trichinosis has been detected only among the Spanish (from Spain). Some of these diseases are absolutely confined to the races or nation alities mentioned, because the local environment here is quite unsuited for their transmission to the native population. For example, there is no instance of any kind of tapeworm or fluke infection among the native population. It is otherwise, however, with hookworm disease. For the Old World worm is now found in many of the West Indians and in some Panamanians. If a sailor infected with aestivo-autumnal malaria from the west coast of Africa should have a sufficient number of gametes in his peripheral blood on arriving here, and be bitten by Anopheles albimanus, 60 per cent. Of the mosquitoes would become infected and might later transmit the disease to others the secondary cases would clinically conform to the local type of malaria, and there would be no difference in morphology between the plasmodia and those in cases seen here.
