[Acute segmental hemorrhagic antibiotic-associated colitis].

Three cases of acute segmental hemorrhagic antibiotic-associated colitis are described occurring in three male adults between 30 and 33 years of age after treatment with oral ampicillin or amoxicillin because of upper respiratory tract infection, tonsillitis, or HLO eradication therapy, respectively. All presented with cramping abdominal pain and bloody diarrhoea of acute onset, however, microbial analysis of fecal samples was negative. Endoscopy showed right-sided segmental hemorrhagic colitis.

Cure with omeprazole plus amoxicillin versus long-term ranitidine therapy in Helicobacter pylori-associated peptic ulcer bleeding.

Background: Long-term prophylaxis with ranitidine reduces the risk of recurrent bleeding in patients with a history of bleeding peptic ulcers. To date, no randomized study has been performed to compare cure of Helicobacter pylori infection versus H2 blocker prophylaxis in patients with bleeding peptic ulcer.

Methods: In a prospective randomized study, 95 consecutive patients with H.

Management of esophageal perforations after therapeutic upper gastrointestinal endoscopy.

Background: Esophageal perforation is one of the most dreaded complications in therapeutic gastrointestinal endoscopy. We assessed the frequency of esophageal perforation after endoscopic procedures in a highly specialized endoscopy unit and compared clinical outcomes in patients undergoing either surgical or conservative management.

Methods: From January 1985 to June 1996, 1011 instrumental endoscopic procedures (dilatation and bougienage) were performed in our department.

[Endoscopic fibrin gluing of a pancreatic duct fistula following acute pancreatitis].

History And Clinical Findings: A 45-year-old patient was admitted because of frequent attacks of upper abdominal pain after food intake. The pain episodes had started shortly after a bout of acute pancreatitis. Physical examination was unremarkable except for mild pain on palpation of the left lower abdomen.

[The feasibility of ultrasonography for the evaluation of stomach motility disorders].

The value of measuring gastric emptying time by ultrasonography in disorders of gastric motility was first assessed in a control group (26 men, 24 women; mean age 51 [23-83] years. Some were healthy volunteers, others were patients without any gastrointestinal disease, the results serving to standardize the method (planimetry of the antrum; 300 ml water as test substance). The mean gastric emptying time (GET) was 24.

[Effect of the geometry of atherosclerotic carotid artery lesions on their angiography image--an arteriography study].

Atherosclerotic lesions of the carotid arteries are frequently located eccentrically and are of asymmetric configuration. For their angiographic detection at least two orthogonal views are mandatory. The carotid bifurcations, the proximal internal carotid artery and the carotid siphon can be visualised free from vessel overlap only via often mandatory lateral views that must be obtained by selective arteriography (IA DSA).

[Distribution pattern of atheromatous lesions of the carotid circulation--significance for the angiographic strategy of cerebrovascular insufficiency].

Atherosclerosis of the cervico-cerebral arteries is a generalized disease which frequently involves the whole carotid system. The bifurcations (48.7%), the proximal 2 cms.
