CONTAGION - DIABETES MELLITUS.
There are some remarkable cases reported in the literature of this disease which speak in favor of the possible transmission of diabetes from one individual to another. To the late R. Schmitz is due the credit of having directed attention to this possibility. Out of his rich experience (2,320 cases of diabetes) he was able to gather 26 in stances of this kind. Persons known to be in perfect health, with few exceptions married people and usually the wives, became diabe tic after having for a long period taken care of a person with diabetes, living with him continuously in intimate relations, sleeping in the same room, and often kissing him. In not a single case could heredi tary influences be alleged, and in no instances was the one last at tacked related by blood to the first sufferer. Furthermore there was nothing else that could be looked upon as a cause for the occurrence of the diabetes ; the persons had never indulged especially in sugar, they had not suffered from gout, nor was it possible to allege any other etiological moment. Schmitz opens the question, therefore,
whether there is not a special form of diabetes which can be trans mitted from one person to another. Similar instances are related in the monographs of Reil and Th. Henke, Bouchardat, Seegen, and in numerous reports of single cases of diabetes. Generally speaking, however, this mode of origin of the disease, if ever active, is extremely rare. And, furthermore, the possibility of the transmission of dia betes from one individual to another is strenuously contested (Senator), the instances alleged by Schmitz being explained by the fact that persons living together are naturally exposed to the same injurious influences.
