This study investigated the influence of feeding on gastric acid suppression in Helicobacter pylori-positive patients treated with intravenous infusions of proton pump inhibitors (PPIs) or with H2-receptor antagonists (H2-RAs) after bleeding from a gastric ulcer. ⋯ Gastric acid suppression during the administration of an H2-RA or a PPI soon after the cessation of gastric bleeding was scarcely affected by feeding. It may well be that H. pylori-positive patients with bleeding gastric ulcer can resume a regular diet and return to work soon after bleeding ceases.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors. The molecular etiology is the result of mutations in the c-Kit gene. ⋯ Based on this potential to inhibit critical c-Kit function in GISTs, case studies have reported effective outcomes following treatment with STI571. This case report describes a highly effective use of STI571 in a 54-year-old woman with multiple liver metastases from a GIST originating in the duodenum.

Gastrointestinal stromal tumors (GISTs) are usually refractory to standard chemotherapeutic agents. We successfully treated a patient with a tyrosine kinase inhibitor (STI571) for GIST with peritoneal dissemination and liver metastases. ⋯ The tyrosine kinase inhibitor STI571 may be effective against GISTs.
