The aim of any operation for chronic duodenal ulcer is to reduce the amount of acid produced by the stomach, sufficiently to allow the ulcer to heal. Complete division of the vagi usually satisfies this criterion, but in some the reduction obtained, as measured by the augmented histamine test (Kay, 1953), may only be small (Sircus and Small, 1964). The patients in whom an adequate reduction is ...

Buruli ulcer is a neglected emerging disease that has recently been reported in some countries as the second most frequent mycobacterial disease in humans after tuberculosis. Cases have been reported from at least 32 countries in Africa (mainly west), Australia, Southeast Asia, China, Central and South America, and the Western Pacific. Large lesions often result in scarring, contractual deformi...

Except in rare cases, the stomach can withstand exposure to highly concentrated hydrochloric acid, refluxed bile salts, alcohol, and foodstuffs with a wide range of temperatures and osmolarity. This is attributed to a number of physiological responses by the mucosal lining to potentially harmful luminal agents, and to an ability to rapidly repair damage when it does occur. Since the discovery i...

Upper gastrointestinal bleeding is a major adverse event of non-steroidal anti-inflammatory drugs (NSAIDs), and co-administration of proton pump inhibitors and H2 receptor antagonists has been established as a means of preventing such an effect. However, the incidence of bleeding associated with NSAID-induced ulcers under conditions where such strong anti-acid agents are used for prevention has...

AIM To substantiate the claims of Unani and Arabian traditional medicine practitioners on the gastroprotective potential effect of a popular spice anise, "Pimpinella anisum L." on experimentally-induced gastric ulceration and secretion in rats. METHODS Acute gastric ulceration in rats was produced by various noxious chemicals including 80% ethanol, 0.2 mol/L NaOH, 25% NaCl and indomethacin. A...

The possible carcinogenic effects of antisecretory agents used in the treatment of gastric and duodenal ulcer were investigated in a population based cohort study of 16,739 patients who were prescribed the H2-antagonist cimetidine between 1977 and 1981. An excess risk for gastric cancer was observed, with a relative risk of about 10 in the first year after beginning use of the drug, which decre...

Topical antiseptics are commonly used in the management of minor wounds, burns, and infected skin. These agents are widely used by health professionals and are often self-prescribed by patients as they are easily available over-the-counter. This case illustrates a 73 year old man who presented with a non-healing wound on his right forearm for 4 weeks. The wound started from an insect bite and p...

Two hundred and thirty five consecutive patients with a life threatening complication of peptic ulceration, who either died or required emergency surgery, have been studied over a 36 month period. Seventy eight of these high risk patients died; 25 at home, 19 in hospital without surgery and 34 postoperatively. Ninety eight patients had bleeding ulcers, 132 perforated ulcers and five had both bl...

Two patients with Buruli ulcer (infection by Mycobacterium ulcerans) in the Foya region of Liberia have recently been reported. We describe three more patients which together with the two original patients establish the Mayor River basin as an endemic area of Buruli ulcer. We also describe a patient from the St. Paul River basin. This disease, unrecognized in Liberia before 1978, now seems to b...

BACKGROUND AND AIMS The genetic trait plays a part in the pathogenesis of peptic ulcer disease. To identify a DNA marker for peptic ulcer disease, the association between the restriction fragment length polymorphism (RFLP) of the pepsinogen C (PGC) gene and peptic ulcer disease was investigated. PATIENTS AND METHODS One hundred and seventy seven unrelated controls, 75 patients with gastric ul...
