Are these diseases auto-immune in origin, for instance? I can't remember the last time I cared for a Diabetic with PD (my med-surg clinical division specialized in Diabetes, Emphysema, and cardiac problems). Diabetics experience frequent hospitalizations because of the unique variety of problems that disease precipitates. PD is not among them. However, there might be a link between the high incidence of PD and Diabetes in the state of Maine - and I say that in all seriousness. ------ Mary Ann
