We report a 51-year-old female patient with adult-onset type II citrullinemia (CTLN2) who had a history of pancreatoduodenectomy for duodenal somatostatinoma with metastases to regional lymph nodes at age 49 years, paying special attention to indications for liver transplantation. At age 50 years,
A case of somatostatinoma syndrome in a 30-year-old woman is presented. Basal levels of growth hormone and of pancreatic and gastric hormones were reduced and the response of growth hormone, insulin and C-peptide to stimuli such as arginine, glucose, glibenclamide and calcium was virtually
A patient with a somatostatin (SRIH)-secreting islet cell tumor, whose only symptoms were dyspepsia and anemia, is described. The diagnosis of somatostatinoma was based on high plasma SRIH concentrations and immunocytochemical findings. The pancreatic exocrine response to secretin was decreased,
The plasma levels of somatostatin (SRIF) were studied in normal subjects and patients with various disorders by a sensitive and specific radioimmunoassay. In 45 normal subjects, the fasting plasma SRIF concentrations were 13.3 +/- 5.3 pg/ml (mean +/- SD). Very high concentrations of plasma SRIF,
A case of somatostatin and pancreatic polypeptide (PP) producing tumor of the pancreas is presented. A 65-year-old woman was admitted for the evaluation of the tumor in the right upper quadrant of the abdomen. Clinical abnormalities included diabetic glucose intolerance, pancreatic insufficiency and
Production and secretion of somatostatin (SRIF) were studied using a carcinoembryonic antigen (CEA)-producing cell line (QGP-1) established from a human pancreatic islet cell carcinoma. High concentrations of SRIF (274 +/- 51 ng/mg of protein, mean +/- SD, n = 5) and CEA (3083 +/- 347 ng/mg of
A 33-year-old woman with a 2 month history of vague ill health was admitted to hospital in hypoglycaemic coma. Preoperative investigation suggested malignant insulinoma as the probable cause of illness, but immunohistological examination of the tumour showed it to consist mainly of
