Calcitonin gene-related peptide (CGRP) has recently been identified in central and peripheral nerve fibres, including those of blood vessels supplying the exocrine pancreas, and in pancreatic islet cells. Moreover, receptors have been characterised in the same tissue. The present study examined the effects of human CGRP and of calcitonin on exocrine pancreatic secretion and on islet cell function in nine healthy volunteers. CGRP (300 ng/kg/h) caused, respectively, a 25% and 31% inhibition of caerulein stimulated trypsin and amylase output which was similar to that seen with calcitonin (300 ng/kg/h). Arginine stimulated insulin and glucagon release was unaffected by either CGRP, or calcitonin. Calcitonin gene-related peptide caused cutaneous flushing, but did not affect the pulse rate or arterial blood pressure in the doses tested. Calcitonin gene-related peptide inhibits exocrine pancreatic secretion in vivo in man, but does not affect islet cell hormone release.

Laparoscopic cholecystectomy has emerged as the treatment of choice for uncomplicated cholelithiasis. Despite early concerns, many surgeons have applied this new technique to more complicated biliary tract disease states, including biliary pancreatitis. To evaluate the safety of laparoscopic cholecystectomy in this setting, we retrospectively reviewed 29 patients with clinical and laboratory evidence of biliary pancreatitis who underwent this procedure between March 1990 and December 1992. The severity of pancreatitis was determined by Ranson's criteria. Two patients had a Ranson's score of 6, one of 5, one of 4, five scored 3, nine scored 2, nine also scored 1, and two patients scored 0. The mean serum amylase level on admission was 1,610 (range 148 to 7680). All patients underwent laparoscopic cholecystectomy during the same hospital admission for biliary pancreatitis, with the mean time of operation being 5.5 days from admission. Operative time averaged 123 minutes (range 60-220 minutes). Intraoperative cholangiography was obtained in 76 per cent of patients. Three patients had choledocholithiasis on intraoperative cholangiography and were treated with choledochoscopy, laparoscopic common bile duct exploration, and saline flushing of the duct. The mean length of hospital stay was 11 days (range 5-32 days). There were seven postoperative complications requiring prolonged hospitalization with all but one treated non-operatively. One patient with a preoperative Ranson score of 6 developed necrotizing pancreatitis and subsequently required operative pancreatic debridement and drainage. There were no deaths in this series and no postoperative wound infections. The average recovery period for return to work was 2 weeks. These statistics compare favorably with literature reports for open cholecystectomy in biliary pancreatitis.(ABSTRACT TRUNCATED AT 250 WORDS)

We have experienced a case of iodide mumps after CT examination with 100 ml of iopamidol. The patient was a 70-year-old woman with a history of right nephrectomy due to right renal cancer. She underwent CT examination to explore local recurrence and abdominal metastases including lymph node and liver metastases. Three hours after the CT examination, she complained of nausea, vomiting, facial flushing, bilateral jaw pain, and fever. The laboratory findings 12 hours after CT examination showed increased white blood cells and elevated serum amylase enzyme. Analysis of the amylase fraction showed that 86% originated from the salivary glands. She was admitted to the hospital, and the symptoms continued for four days, with decreasing severity. Anti-inflammatory therapy was performed, and the patient was discharged six days after the event.

The effect of flushing flow rate during multiple organ procurement (MOP) on viability of the liver, pancreas, and intestine were investigated in porcine multivisceral transplantation. Splanchnic organs were flushed in situ with 50 ml/kg of 4 degrees C UW solution via the aorta using a pump at a flow rate of 10, 30, or 50 ml/kg/min. After storage and transplantation, we assessed the clearance of hyaluronic acid (CHA) for hepatic endothelial cells function, liver enzymes, amylase, and histology. Two-day survival was 17% in the 10 ml/kg/min group and 67% in other groups. The former group had inadequate flushing out of the hepatic and intestinal grafts, resulting in aggravation of CHA and intestinal tissue injury. At the flow rate of 30 ml/kg/min, the viability and integrity of all organs were well maintained. We conclude that the optimal flushing flow rate would differ for each organ, therefore the common flow rate acceptable for any of the individual grafts should be applied in MOP.

Crystalline nicotinic acid (immediate-release niacin) is effective therapy for lipoprotein regulation and cardiovascular risk reduction. However, inconvenient regimens and unpleasant side effects decrease compliance. Sustained-release formulations designed to circumvent these difficulties increase hepatotoxicity. Niaspan, a new US Food and Drug Administration (FDA)-approved, once-daily, extended-release form, has been found effective and safe in short-term trials. The long-term efficacy and safety of Niaspan lipid monotherapy was studied in 517 patients (aged 21-75 years) for < or =96 weeks in dosages < or =3,000 mg/day. Primary efficacy endpoints were low-density lipoprotein (LDL) cholesterol and apolipoprotein B (apo B) changes from baseline; secondary efficacy endpoints were changes in total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, lipoprotein(a), and total cholesterol/HDL-cholesterol ratio; safety data included adverse events and laboratory values over the 2-year study period. LDL-cholesterol levels decreased significantly: 18% at week 48 and 20% at week 96; apo B reduction was similar (16% decrease at week 48 and 19% at week 96). Large elevations in HDL cholesterol (26%, week 48; 28%, week 96) allowed only modest decreases in total cholesterol (12% and 13%, respectively), whereas total cholesterol/HDL-cholesterol ratio decreased by almost one third. Triglyceride and lipoprotein(a) levels were decreased by 27% and 30%, respectively (week 48), and by 28% and 40%, respectively (week 96). All changes from baseline were significant (p <0.001). Niaspan was generally well tolerated, although flushing was common (75%); however, there was a progressive decrease in flushing with time from 3.3 episodes in the first month to < or = 1 episode by week 48. Aspirin was used by one third of patients before Niaspan dosing to minimize flushing episodes. Although serious adverse events occurred in about 10% of patients, none were considered probably or definitely related to Niaspan. Adverse events in general varied widely, but their true relation to the study drug is difficult to ascertain without a placebo (control) group. No deaths occurred. There were statistically significant changes in hepatic transaminases, alkaline phosphatase, direct bilirubin, phosphorus, glucose, amylase, and uric acid. However, these changes were mostly small and are not likely to be biologically or clinically significant (the decrease in phosphorus is a new finding in niacin therapy). No myopathy was observed. Thus, this long-term study confirms the earlier short-term findings that Niaspan is safe and effective as monotherapy in plasma lipoprotein regulation.
