In spite of the recent important advances made in diabetic treatment by the studies of Allen, Joslin, Mosenthal and others, our profession at large has failed to profit in a corresponding degree. The reasons are not difficult to ascertain. Success in the treatment of diabetes lies in the smooth coordination of clinical experience in the disease with a practical system of diabetic dietetics and accurate chemical laboratory methods. Neither the general practitioner nor, indeed, the general internist can be expected to meet these severe requirements, as both treat too few diabetics at any given time to permit of elaborate dietetic management. The result is that the treatment of diabetes, at present, is carried out successfully by a relatively few physicians who have the help of a specially modified institutional system. However, the management of this difficult disease must of necessity still be largely conducted by the general practitioner and internist.
