During 1880 patient-months of treatment with continuous subcutaneous insulin infusion in 101 patients with IDDM, 36 episodes of acute, severe loss of glycemic control, including 29 with significant ketoacidosis, occurred in 20 patients. Fifteen episodes were attributable to failure of insulin delivery to the patient while 13 were precipitated by infection. Insufficiently frequent blood glucose monitoring, failure by patients to detect mechanical and technical problems with infusion systems, failure to adhere to "sick day" regimens, and delay in seeking medical help all contributed to the progression of a number of episodes. Thirst, nausea, and vomiting were the common clinical manifestations of decompensation; and the degree of acidemia was often mild in relation to the degree of hyperglycemia. Response to conventional management was usually prompt.

Individuals with insulin-dependent diabetes mellitus (IDDM or type 1 diabetes) are deficient in both insulin and amylin, peptides secreted by the beta cell. We have investigated the effects of amylin replacement therapy employing the human amylin analogue, pramlintide (25, 28, 29-pro-human amylin, previously referred to as AC137), upon the responses to a standardized insulin infusion (40 mU. kg-1. h-1) for 100 min and a liquid Sustacal meal (360 kcal) in 84 healthy IDDM patients. Following baseline evaluations, patients were randomly assigned to receive subcutaneous injections of placebo, 30, 100 or 300 micrograms pramlintide 30 min before meals for 14 days. There was no meaningful difference between adverse events reported by the 30-micrograms pramlintide and the placebo groups, but ten subjects withdrew due to nausea, eight of these in the 300-micrograms dose group. Peak plasma pramlintide concentrations for the 30-micrograms group were 21 +/- 3 and 29 +/- 5 pmol/l on Days 1 and 14, respectively. These values are similar to postprandial plasma amylin concentrations in normal volunteers. The plasma glucose, free insulin, glucagon, epinephrine and norepinephrine concentrations during the insulin infusion test before and after therapy were identical in each of the group. Prior to pramlintide therapy, Sustacal ingestion produced a 4.0-4.8 mmol/l rise in plasma glucose concentrations in each of the groups. Pramlintide therapy reduced postprandial hyperglycaemia as reflected by the 3-h incremental AUCglucose (AUCglucose above or below fasting glucose concentration) Day 1 vs Day 14: 30 micrograms, 322 +/- 92 vs -38 +/- 161 mmol/l.min, p = 0.010; 100 micrograms, 317 +/- 92 vs -39 +/- 76 mmol/l.min, p = 0.001; and 300 micrograms, 268 +/- 96 vs -245 +/- 189 mmol/l.min, p = 0.077. Thus, pramlintide therapy with these regimens did not appear to impair either in vivo insulin action or the counter-regulatory response to hypoglycaemia but did show a clear effect of blunting postprandial hyperglycaemia following a standardized meal.

Despite being the largest part of the human gastrointestinal (GI) tract, the small intestine accounts for only 1-1.4% of all GI malignancies. Adenocarcinoma is the most common primary small bowel malignancy, with the most common site being the duodenum. On the other hand, squamous cell carcinoma (SCC) of the duodenum is extremely uncommon. We report the first case of mixed adenocarcinoma and SCC occurring in the third part of duodenum (D3). Our patient, a 64-year-old female with history of GERD, hypertension, and IDDM presented with 4 weeks of nausea, vomiting, and abdominal pain. Tomographic imaging of her abdomen demonstrated a distended stomach and a proximal duodenum with narrow caliber changes at the level of D3. An EGD revealed a tight stricture at D3 that could not be traversed. Stricture biopsies revealed duodenal mucosa with two small foci of SCC (positive for p63 and CK5/6) and adenocarcinoma (positive for CK7 and Moc31). Peritoneal metastases were detected on exploratory laparotomy, making the tumor surgically incurable. As she progressively declined and with worsening liver enzymes and general debility, she was not a candidate for chemotherapy and was eventually discharged on home hospice. Small bowel SCC/adenocarcinoma is an exceedingly uncommon cancer, making further case reports such as ours important to understand the nature of this entity and establish management guidelines.
