Objective : to study the ulcer recurrence rate of Helicobacter pylori-positive duodenal ulcers at 1 yr after eradication of the bacteria by triple therapy. Method : Patients with H. pylori-positive duodenal ulcers were randomized to receive either triple therapy for 1 wk plus omeprazole for 4 wk (THple+OMP) (n = 78), or omeprazole alone (OMP) for 4 wk (N = 77). Patients were followed up every 3 months for symptom enquiry. At 1 yr, all asymptomatic patients were invited to attend for gastroscopy. Results : At 8 wk, 16 patients in the OMP group and four in the Triple+OMP group had an ulcer. During the 1-yr period, 12 patients in the OMP group and no patient in the Triple+OMP group developed symptomatic ulcers. At follow-up endoscopy at 1 yr, another 10 ulcers were detected in the OMP group and two in the Triple+OMP group. Fifteen patients in the OMP group and 13 in the Triple+OMP group were lost to follow-up. In total, ulcers were de-tected in 39 of 61 (64%) assessahle patients in the OMP group, and in six of 65 (97o) assessahle patients in the Triple+OMP group after I yr (χ2 test: p < 0.001). Of the patients whose H, pytori were successfully eradicated hy Triple+OMP at 8 wk, 90% remained H. pylori negative at 1 yr. Conclusion : Triple therapy for 1 wk eradicates H, pylori infection and significantly reduces duodenal ulcer relapses.  相似文献

An original method is proposed for treatment of long-standing intractable wounds and trophic ulcers using viable cryopreserved allodermotransplants and a distant air-plasma treatment. The main source of the allodermotransplants is the cadaverous skin. It was shown that the cadaverous skin taken during 17 hours after the donor's death was viable. The maximum period for storage of the viable skin when the worked out preservative is used at the temperature regimen -18 degrees C is 10 days, and at -70 degrees C it can be as long as 45 days. The analysis performed included 101 patients with long-standing intractable wounds and trophic ulcers. In 51 of them the new worked out method was used. An analysis of clinical and histomorphological data has proved that the application of the viable cryopreserved allodermotransplants and distant air-plasma treatment favor the better course of reparative processes. By the end of the forth week the wounds were completely closed in 19.7% of patients, the wound areas were considerably less (more than by 50% of the initial size) in 43.1%, less reduction of the wound area (less than 50% of the initial size) in 27.4%, in 9.8% there was no effect. No negative results were noted. It should be noted that closure of the tissue defect can be achieved by stimulation of the physiological regeneration of the patient's tissues. This method of regeneration of the skin is effective in trophic ulcers, long-standing intractable wounds and is also recommended in case of deficit of donor resources or when the severe state of the patient does not allow active surgical treatment.  相似文献

The efficacy of nimodipine in the prophylaxis of migraine was assessed in a double-blind, placebo-controlled, cross-over study carried out on 33 patients, 20 of whom suffered from classic and 13 from common migraine. Four patients dropped out, but not as a result of the side effects of the drug. The duration of drug treatment was 8 weeks. The dosage used was 30 mg four times daily. Nimodipine proved to be better than placebo, the number of migraine attacks and severity of headache showing a significant reduction. The drug was well tolerated and no marked side effects were noted. The results suggest that nimodipine is a useful new prophylactic drug for migraine, but further studies are needed before its final value can be evaluated.  相似文献
