Upper gastrointestinal hemorrhage clinical, radiological and endoscopic correlation of 100 consecutive cases.

One hundred consecutive cases of upper gastrointestinal hemorrhage were studied clinically, radiologically and endoscopically. Erosive gastritis, duodenal and gastric ulcer, and bleeding esophageal varices accounted for 85% of the cases. The presenting sign of hematamesis or melena was of no value in localizing the bleeding site relative to the pyloric sphincter. Erosive lesions of the esophagus and stomach were suspected clinically in less than 50% of the cases and were the lesions least amenable to radiologic diagnosis and where early endoscopy was most useful. Our observations demonstrate again the frequent association between ethanol or aspirin ingestion and erosive gastritis.

Gastric mucosal morphology and faecal blood loss during ethanol ingestion.

The faecal blood loss of six alcoholic subjects with normal gastric mucosa, six with superficial gastritis, and six with atrophic gastritis was studied before and during ingestion of 40% v/v ethanol using (51)Cr-tagged red blood cells. No significant change in faecal blood loss was observed in the normal mucosa and superficial gastritis groups but all subjects with atrophic gastritis had significant increases of faecal blood loss during ethanol ingestion. These observations suggest that gastric mucosal morphology may be an important determinant of gastric mucosal bleeding during the ingestion of alcohol.

The effect of stress on colon motor and electrical activity in irritable bowel syndrome.

The present investigation was designed to study the role of stress on the physiologic mechanisms of the colon in irritable bowel syndrome (IBS). Patients with IBS were compared with normal controls during resting and stress (mental arithmetic, cold pressor, and fear stressor). The results indicated that IBS patients had significantly higher motor activity than normals in the resting state but did not differ from them in the mean dominant frequency of the basal electrical rhythm (BER) or the proportion of the time they had 2-4 cycles per minute (cpm) slow-wave activity. Stress significantly increased motor activity in both groups although they did not differ significantly from each other during stress. Stress increased the proportion of 2-4 cpm slow-wave activity in IBS patients, but decreased in the controls. The type of stressor, however, did not influence either motor or electrical activity. Although IBS patients were significantly older than the controls and scored higher on the MMPI scales of Hypochondriasis, Hysteria, and Depression, these factors did not significantly influence differences in motor or electrical activity between the groups. The results are discussed in terms of the role of learning in the colon.
