<prompt> Pancreatic cholera is characterized by all except:HypochlorhydriaHypokalemiaGlucose intoleranceHypocalcemia  <response>: Answer is D Hypocalcemia: Pancreatic cholera is a Pancreatic endocrine tumor, most commonly of the Delta cells, characterized by net secretion of salt and water by gut: Features of Pancreatic cholera : - Severe watery diarrhea Q flushing weight loss - Hypokalemia Q - Hypochlorhydria Q - Hypercalcemia Q not Hypocalcemia - Hyperglycemia Q - Inordinate fecal water and electrolyte loss - Pancreatic cholera is synonymous with Verner - Morrison Syndrome or WDHA Syndrome WDHA Syndrome Watery diarrhea Hypokalemia Achlorhydria Pancreatic cholera results from excessive secretion of VIP from endocrine tumors i.e. VlPomas VIP is an impoant neurotransmitter ubiquitously present in CNS and G.I. tract Known actions of VIP explain most features of the clinical syndrome. These include : - stimulation of small intestinal chloride secretion - effects on smooth muscle contractility - inhibition of acid secretion - vasodilatory effects
