[Clinical aspects and course of drug-induced upper digestive hemorrhage].

In a series of 500 patients admitted to hospital for upper digestive hemorrhage, the authors studied the influence of taking drugs on the clinical characteristics and course of the original disease. Taking aspirin is exceptional before rupture of esophageal varices. One may isolate a homogenous group of elderly women consuming aspirin and another anti-inflammatory drug, and bleeding from a gastric ulcer. One may also isolate another group of men, bleeding from acute gastro-duodenal lesions after taking aspirin alone. If one considers apart portal hypertension, owing to its extreme gravity, one may note that the prognosis depends on the age. One patient out of five, dies of hemorrhage after the age of 60 years. Taking an anti-inflammatory drug at this age is thus not harmless.

[Cholestatic hepatitis with a chronic course. 7 cases].

Cholestatic hepatitis, whilst having a longer course than cytolytic forms, in general regresses in a few months. The authors report here seven cases of cholestatic hepatitis lasting for more than 18 months. These chronic forms have certain characteristic features: - female predominance (6 cases out of 7). - a severe degree of cholestasis with, in particular, marked elevation of lipids, cholesterol and alkaline phosphatase. - the absence of Australia antibody and antigen, together with the absence of anti-smooth muscle antibody and anti-mitochondrial natibody. - a decrease in the number of permeable biliary canaliculi in the portal spaces. - a decrease in the number of permeable biliary canaliculi in the portal spaces. - a course which appears to be little influenced by various therapeutic measures. Although the final course seems satisfactory on the majority of cases, the possibility of a slow cirrhogenic transformation cannot be excluded in certain instances.

Use of caerulein with submaximal doses of secretin as a test of pancreatic function in man.

The pancreatic exocrine secretory response to different combinations of the pancreozymin-like peptide caerulein and secretin was studied in 110 healthy control subjects and 32 patients with pancreatic disease. A combination of 0-5 CU/kg-h secretin and 75 ng/kg-h caerulein provided maximal or near-maximal stimulation of the secretion of both bicarbonate and pancreatic enzymes. The combination of stimulant peptides in the above doses was found to give excellent separation between the secretion of bicarbonate, lipase, and chymotrypsin of the control group and patients with chronic pancreatitis. A combination of caerulein and secretin represents a safe, reliable, and effective mean of stimulating pancreatic exocrine secretion for the purpose of testing pancreatic function.
