Some alcoholics have a regular daily alcohol consumption of more than 100 g. In preliminary observations we had the impression that the claimed alcohol intake in such 'heavy drinkers' was higher than could be accounted for by the ethanol elimination rate as measured routinely at 10 mmol/l (0.5 g/l). We therefore measured the ethanol elimination rate at very(More)
The purpose of this investigation was to evaluate the effect of temporary ischemia created during the surgical preparation of the colon for resection on transmural migration of bacteria and passage of endotoxin through the ischemic wall of the canine colon. Eighteen dogs were used: in fourteen the colon was devascularized by ligating all marginal vessels.(More)
STUDY OBJECTIVE To compare the composition of gases generated by bipolar hysteroscopic vaporizing electrodes using electrolyte-rich medium (normal saline) with those of monopolar vaporizing electrodes using nonelectrolytic medium (1.5% glycine). DESIGN In vitro study (Canadian Task Force classification II-1). SETTING Laboratory. INTERVENTION Fresh(More)
OBJECTIVE This study estimates the reduction in greenhouse gas (GHG) emissions resulting from 840 telemedicine consultations completed in a 6-month time period. Our model considers GHG emissions for both vehicle and videoconferencing unit energy use. Cost avoidance factors are also discussed. MATERIALS AND METHODS Travel distances in kilometers were(More)
Pancreatic secretion of zinc and copper in duodenal juice were measured in 7 healthy persons and in 9 patients with chronic pancreatitis. Stimulation with cholecystokinin and secretin increased secretion of zinc in healthy persons but not in patients. Copper secretion was not influenced. In patients with chronic pancreatitis, the correlations between zinc(More)
This study was designed to test the efficacy of 400 mg fleroxacin given orally as a single dose or once daily for 3 days against acute bacterial diarrhea. A group of 508 adults with acute diarrhea were entered into a randomized, double-blind, placebo-controlled, multicenter trial. Patients were examined and asked about numbers of liquid stools daily for 3(More)
In order to evaluate the possible relation between hepatic function and hemodynamics and the increased humoral immune response of cirrhotic patients, titres of antinuclear antibodies (ANA) and smooth muscle antibodies (SMA) and concentrations of immunoglobulin (Ig) G, A and M were determined in 74 consecutive patients with alcoholic liver cirrhosis.(More)
