[Water and electrolytes disorders in apudocarcinomas (author's transl)]

The authors report an analytic study of hydroelectrolytic disorders in patients with APUD tumors. In most of the cases a diarrhea occurs. The type of this diarrhea is: -- a motrice diarrhea (in the great majority of carcinoid tumor and medullary carcinoma of the thyroid); -- a secretory diarrhea (W.D.H.A.): it is the case in gastrinoma (gastric hypersecretion), in secretinoma (pancreatic hypersecretion) and in vipoma (intestinal hypersecretion). The others disorders could be no diarrhea dependant (hyponatremia by ADH hypersecretion, hypercalcemia). The personal cases of the authors are: 12 medullary carcinoma of the thyroid, 19 enteraminoma and 2 others apudomas.
