[Pancreatic cancer revealed by hyperosmolar coma: report on two cases (author's transl)].

Hyperosmolar diabetic coma revealed the presence of a pancreatic cancer in two patients. The first case was a 59-year-old man, without a history of diabetes, treated with prednisone for jaundice and marked weight loss over the last month, and admitted in hyperosmolar coma (346 m0sm/l). After recovery from the acute episode, a diagnosis of adenocarcinoma of the head of the pancreas was established following operation. The patient died six months later. The second case, a 71-year-old man also without a history of diabetes, was admitted in hyperosmolar coma (315 m0sm/l) during the course of a pulmonary infection. Rapidly fatal cholostatic jaundice appeared one year later. An adenocarcinoma of the head of the pancreas was demonstrated at autopsy. The diagnostic criteria in both cases were those of hyperosmolar diabetic coma. Though cases of combined diabetes and pancreatic cancer are well documented, only one case of hyperosmolar coma and cancer of the pancreas has been reported in the published literature. The pathogenesis of hyperosmolar diabetic coma is discussed. The fact that it developed during the course of a pancreatic affection could be explained by a functional reduction in insulin secretion, associated with a triggering factor such as dehydration, infection, hypoglycemic agent administration, etc... The onset of hyperosmolar diabetic coma in an elderly patient without a history of diabetes, especially with associated marked weight loss, should lead to investigation for a possible pancreatic cancer.

[Papillary thyroid cancer lying within a toxic adenoma (author's transl)].

The association of hyperthyroidism and thyroid cancer is rare. The commonest finding is multilobular goitres. When a toxic adenoma is associated with a thyroid cancer they are usually clearly separate lesions. A thyroid cancer lying within a toxic adenoma, as in this case, is a much rarer occurrence, and a review of the published literature suggests that the relatively frequent association of the two lesions is fortuitous. The possibility of a cancer occurring near, or within a toxic adenoma, is an argument in of surgical treatment of these formations.

[Severe hypercalcemia during hyperthyroidism].

A particularly high hypercalcemia (141 mg/ml) was observed in a man with Graves' disease. An intense muscle asthenia, with lack of dynamism and vomiting which may cause dehydration, are the most suggestive signs of hypercalcemia. Bone biopsy and above all parathormone estimations permit one to eliminate associated hyperparathyroidism. The efficacy of mithramycin used alone, without any other hypocalcemic drug, was remarkable. The direct responsibility of thyrotoxicosis as a cause of the calcium disorder seems undoubted but the precise mechanism of the hypercalcemia remains unexplained.
