A 37-year-old chronic alcoholic female was admitted with epigastric pain, complete anorexia, vomiting and diarrhoea. She was dehydrated, and had polypnoea. Laboratory investigations revealed severe metabolic acidosis (pH 7.14) with a major anion gap (37.4 mmol.l-1), and ketone bodies in blood and urine. Blood glucose concentration was 6.1 mmol.l-1, there was no glycosuria. Rehydration (2 l.day-1 of 5% glucose) together with sodium bicarbonate (500 ml of 1.4% sodium bicarbonate over the first four hours) normalized the pH (7.37). The ketone bodies disappeared on the following day. During the acute illness, were found high blood levels of glucagon and low levels of insulin. The diagnosis of alcoholic ketoacidosis, the pathogenesis of which remains unknown, is discussed.

Four patients with pancreatic disease received glucagon intravenously. In two a definite decrease in the volume of pancreatic exocrine secretion was shown, and in one of these pancreatic juice protein and bicarbonate levels also fell. Two patients with acute pancreatitis had pronounced relief of epigastric pain associated with falls in plasma amylase after intravenous glucagon.Several mechanisms could account for the possible beneficial effect of glucagon in pancreatitis, and further studies of its use in this disease are justified.

A 28-year-old man presented with epigastric pain and obstructive jaundice associated with a histologically and immunologically unusual variant of carcinoid tumor involving the ampulla of Vater. The tumor contained abundant psammoma bodies and exhibited immunoreactivity only for somatostatin. Immunoperoxidase studies for insulin, glucagon, vasoactive intestinal peptide, calcitonin, serotonin, and ACTH had negative results. In contrast to most somatostatinomas of pancreatic origin, clinically this ampullary somatostatinoma was not accompanied by features of the somatostatinoma syndrome. A literature review of the clinical and hormonal features in reported cases of gastrointestinal and pancreatic somatostatinomas is presented.

A golden yellow polyp was detected in the gallbladder of a 64-year-old man who presented with epigastric pain. The lesion was composed of clear polygonal cells arranged in a trabecular and glandular pattern. The tumor invaded through the wall into the perimuscular subserosal layer. Immunohistochemical stains showed that neoplastic cells were positive for chromogranin A, synaptophysin, somatostatin, gastrin, and pancreatic polypeptide and negative for glucagon, serotonin, insulin, S100 protein, and inhibin. This tumor resembles the recently described clear cell endocrine tumors of the gallbladder and pancreas that are associated with von Hippel-Lindau disease. Our patient, however, had neither personal nor family history indicative of von Hippel-Lindau disease. Furthermore, published accounts of clear cell endocrine tumors in von Hippel-Lindau disease describe immunoreactivity for inhibin; the current case was negative for the disease. There may be a subtype of clear cell carcinoid tumor not associated with von Hippel-Lindau disease, which is characterized by its lack of immunoreactivity against inhibin.

Sphincter of Oddi spasm from opioids has been documented, presenting as severe epigastric pain and potentially overlooked in a differential diagnosis. We present a case of sphincter of Oddi spasm from periarticular morphine in a patient under spinal anesthesia, causing severe distress and treated effectively with glucagon. It is important for anesthesiologists using opioids to consider it as a cause of perioperative pain and be familiar with treatment as it may be refractory by conventional use of opioids for pain relief. It is also important to consider the systemic effects of periarticular absorption, as evident by our case.

Liraglutide is a long-acting glucagon-like peptide-1 (GLP-1) analog. GLP-1 analogues are used as a second option treatment for type 2 diabetes and weight management in obese patients. Data in the literature suggests an association between GLP-1 agonist use and acute pancreatitis (AP). Furthermore, it has been suggested that acute pancreatitis is a potential complication of liraglutide therapy and liraglutide should be used cautiously in patients at risk of pancreatitis. This case reported herein was a 44-year-old female diagnosed with acute pancreatitis based on 2 of 3 criteria when she presented to the Emergency Department with epigastric pain, which radiated to her back.
