    There is a need to define Quality of Life and to develop a practical method to measure objectively this aspect in gastrointestinal diseases. This has not been performed in any Asian population. It is proposed that this evaluation be part of future trials in Asia on the basis that Asian patients are culturally, socially and politically different from Westerners.

    Twenty-seven patients with peptic ulcer (19 with duodenal ulcer (DU) and eight with gastric ulcer (GU] refractory to H2-antagonists were treated with 40 mg of omeprazole once daily for 4-8 weeks, depending on the rate of ulcer healing. Clinical assessment, endoscopy and laboratory tests were performed at entry, after 2 and after 4 weeks, and if unhealed, also after 8 weeks' treatment. Ten healed patients were given a maintenance therapy of omeprazole 20 mg daily for up to 12 months during which the patients returned for endoscopy, gastric biopsy and laboratory tests at 3-monthly intervals. The initial treatment healed 15 of 19 (79%) DU patients in 2 weeks and all DU patients by 4 weeks. Seven of eight (87%) GU patients healed in 4 weeks and only one required 8 weeks' treatment. Symptom relief was rapid, with most patients being symptom-free within the first day of treatment. Six patients received 12 months' continuous maintenance therapy, one patient 9 months and three patients 6 months' treatment. All patients remained in remission whilst on omeprazole therapy. No adverse events were reported throughout the study. There were no clinically significant changes in haematology or blood chemistry after healing or during the long-term treatment. Biopsy samples revealed no histological changes in the gastric mucosa at any stage. Omeprazole 40 mg therefore was found to produce rapid healing and symptom relief in Asian patients with H2-antagonist-resistant peptic ulcers. Maintenance therapy with omeprazole 20 mg daily was shown to be safe and effective in preventing recurrence of peptic ulceration.

    148 patients, 79 males and 60 females were seen in 1978 at Medical Unit Universiti Kebangsaan Kuala Lumpur. For majority of the patients the attacks of asthma begin at an early age. History of allergies were found in majority of the patients. Family history of asthma was noted in about 50%. Of the allergens that triggers of an attack of asthma, household dusts, rhinitis and pollen tops the list. Of the food the common allergens were shrimps, eggs and crabs. Most of the above allergens can be avoided or counteracted.

    A double-blind randomized study in 230 Malaysian patients with duodenal ulcer was conducted to compare the proton-pump inhibitor, omeprazole 20 mg, given once daily in the morning, with ranitidine 300 mg, administered once daily at night. After 2 and 4 weeks of treatment, 222 and 220 patients, respectively, were evaluable according to the study protocol. Omeprazole produced significantly higher healing rates than ranitidine at both 2 weeks (75% versus 46%, respectively, P less than 0.0001) and 4 weeks (97% versus 83%, respectively, P = 0.001). Ulcer symptoms were relieved more rapidly by omeprazole than ranitidine. After 2 weeks, daytime epigastric pain was reported by 30% of ranitidine-treated patients but only by 15% of omeprazole-treated patients, which is a statistically significant difference (P = 0.004). No major clinical or biochemical side effects were recorded for either omeprazole or ranitidine. In conclusion, omeprazole 20 mg was found to be superior to ranitidine 300 mg administered once daily for the treatment of duodenal ulcer as measured by ulcer healing and pain relief.
