| ulcer, duodenal | An ulcer (a hole in the lining) of the duodenum (the first portion of the small intestine). Ulcer formation is related to h. Pyloridus bacteria in the stomach, anti-inflammatory medications, and smoking cigarettes. Ulcer pain may not correlate with the presence or severity of ulceration. Diagnosis is made with barium X-ray or endoscopy. Complications of ulcers include bleeding and perforation. Treatment involves antibiotics to eradicate h. Pyloridus, eliminating risk factors, and preventing complications. (12 Dec 1998) |
| ulcer, gastric | A hole in the lining of the stomach corroded by the acidic digestive juices which are secreted by the stomach cells. Ulcer formation is related to h. Pyloridus bacteria in the stomach, anti-inflammatory medications, and smoking cigarettes. Ulcer pain may not correlate with the presence or severity of ulceration. Diagnosis is made with barium X-ray or endoscopy. Complications of ulcers include bleeding, perforation, and blockage of the stomach (gastric obstruction). (12 Dec 1998) |
| ulcer, oesophageal | A hole in the lining of the oesophagus (tube-like organ leading from the throat to the stomach) corroded by the acidic digestive juices secreted by the stomach cells. Ulcer formation is related to h. Pyloridus bacteria in the stomach, anti-inflammatory medications, and smoking cigarettes. Ulcer pain may not correlate with the presence or severity of ulceration. Diagnosis is made with barium X-ray or endoscopy. Complications of ulcers include bleeding and perforation. Treatment involves antibiotics to eradicate h. Pyloridus, eliminating risk factors, and preventing complications. (12 Dec 1998) |
| ulcer, peptic | A peptic ulcer is a hole in the lining of the stomach, duodenum, or oesophagus. A peptic ulcer of the stomach is called a gastric ulcer, an ulcer of the duodenum is a duodenal ulcer, and a peptic ulcer of the oesophagus is an oesophageal ulcer. A peptic ulcer occurs when the lining of these organs is corroded by the acidic digestive juices which are secreted by the stomach cells. Peptic ulcer disease is common, affecting millions of americans yearly. The medical cost of treating peptic ulcer and its complications runs in the billions of dollars annually in the u.s. Recent medical advances have increased our understanding of ulcer formation. Improved and expanded treatment options are now available. (12 Dec 1998) |

| ulcerating granuloma of pudenda | <disease, microbiology> A rare sexually transmitted disease that is caused by Calymmatobacterium granulomatis. This infection is more common in the tropical and subtropical areas such as India, Guyana and new Guinea. There are approximately 100 cases reported annually in the United States. Men are affected more often than women. It is thought to be most commonly acquired through anal intercourse. Symptoms include a small red nodule on the genitalia that may form elevated masses of reddened tissue (granulation tissue). The lesions gradual spread and destroy genital tissue. Diagnosis is via tissue biopsy or culture. Treatment includes antibiotics. (27 Sep 1997) |

| gastric ulcer | <gastroenterology> An ulcer in the mucosal lining of the stomach. Ulcer formation results from gastric inflammation that may be triggered by the use of alcohol, aspirin or non-steroidal anti-inflammatories agents. Symptoms include recurrent abdominal pains (may be relieved by antacids), nausea, vomiting, weight loss and fatigue. Complications include GI bleeding, obstruction, perforation and ulcer penetration into surrounding tissues. Treatment includes the avoidance of alcohol, smoking, aspirin, anti-inflammatories and caffeine.
