The Impact of Small Bowel Resection on the Incidence of Stomal Stenosis and Marginal Ulcer After Gastric Bypass

Background: Stomal stenosis (SS) and marginal ulcer (MU) are reported to occur in 9-20% and 2-13%, respectively, of patients undergoing gastric bypass for morbid obesity. It is hypothesized that decreasing tension on the gastrojejunostomy by performing limited small bowel resection (SBR) would decrease ischemia, thereby decreasing the likelihood of SS and MU. Methods: A retrospective review of 150 consecutive gastric bypass patients operated by one surgeon from 1993 to 1996 was performed. The incidence of SS and MU was compared in patients with and without SBR. Results: The overall rate of SS was 24.0% and that of MU was 9.3%: the incidence of both was 2.0%. The incidence of SS in patients without SBR was 26.9% and with SBR was 19.6%. The incidence of MU in patients without SBR was 8.9% and with SBR was 9.8%. Neither result was statistically significant by Fisher's exact test. Conclusion: There is a trend towards a decrease in the incidence of SS in gastric bypass patients with concomitant SBR although this did not reach clinical significance.     

Approved indications of lipo-PGE1 in Japan

For its peripheral vascular dilating effect and platelet agglutination inhibitory activity, prostaglandin E₁ is used in the treatment of diseases which are likely to cause peripheral circulatory failure or thrombus. In Japan, lipo-PGE₁, which was developed to give it a target-directed nature by modifying the conventional PGE₁, has been used and found to be useful in clinical practice. In this report, we attempt to describe the clinical benefits of lipo-PGE₁ focusing on the diseases which have been approved for its indications.     

消化性溃疡中医辨证分型与胃液微量元素 前列腺素E_2及IgG的关系

为了探讨消化性溃疡中医辨证分型与胃液生化、免疫成分的关系,笔者将胃镜确诊的65例患者进行辨证分型,并同步检测其胃液常量元素、微量元素、前列腺素E_2-(PGE_2)、IgG等指标。结果发现,肝胃不和型胃液镁、铜、锌含量低于正常值,IgG高于正常值;脾虚胃热型胃液钠、铜、锌、PGE_2、IgG低于正常值,而钙含量高于正常值;脾胃虚寒型铜、锌、PGE_2低于正常值,而IgG无差异。说明消化性溃疡辨证分型有其客观生化、免疫基础。     

正常人口腔粘膜不同部位表面感觉的测试

目的 建立正常人口腔粘膜不同部位表面感觉的正常参考值，并测试各年龄组感觉值是否存在差异。方法 利用动静两点辨别觉试验，测试90例健康人口腔粘膜不同部位的表面感觉。结果 舌尖感觉功能最好，其次为舌背、舌腹、颊粘膜、口底和硬腭。健康人的口腔粘膜不同部位的表面感觉随着年龄增长有显著性变化。结论 口腔粘膜不同部位感觉辨别力存在差异，健康人口底、舌腹、舌背、颊和硬腭粘膜感觉功能有增龄性变化。     

Randomized clinical trial of ascorbic acid in the treatment of pressure ulcers

The objective of this study was to assess the effects of ascorbic acid supplementation, 500 mg twice daily in the treatment of pressure ulcers as an adjunct to standardized treatment.

The design consisted of a multicenter blinded randomized trial. The control group received 10 mg of ascorbic acid twice daily.

Patients from 11 nursing homes and 1 hospital participated.

Main outcome measures included wound survival, healing rates of wound surfaces, and clinimetric changes over 12 weeks.

Eighty-eight patients were randomized. Intention-to-treat analysis showed that the wound closure probability per unit time (i.e., the closure rate) was not higher in the intervention group than in the control group (Cox hazard ratio of 0.78 [90% precision interval, 0.44–1.39]). Mean absolute healing rates were 0.21 and 0.27 cm²/week in the intervention and control group, respectively (PI of the adjusted difference: −0.17 to 0.13). Relative healing rates and healing velocities did not show favorable results of ascorbic acid supplementation, either. A panel scored slides of the ulcers with a report mark between 1 (bad) and 10 (excellent). The improvement was 0.45 and 0.72 points per week in the intervention and control group, respectively (PI of the adjusted difference: −0.50 to 0.20). With another clinimetric index we could not show any differences, either.

These data do not support the idea that ascorbic acid supplementation (500 vs. 10 mg twice daily) speeds up the healing of pressure ulcers.     

高压氧在治疗脊髓损伤伴截瘫及肢体慢性溃疡中的应用

本文报告了用高压氧治疗脊髓损伤伴截瘫患者１２例，肢体慢性溃疡８例。将患者置于２个大气压的单人氧舱内，每次９０ｍｉｎ。前者疗程为１周，每日２次。后者疗程为２周，每日１次。治疗结果：脊髓损伤伴截瘫患者中８例有明显而有意义的功能恢复，占６６．６％。慢性溃疡患者中有３例愈合，４例好转，有效率为８５％。作者认为：早期使用高压氧是治疗急性截瘫，尤其是不完全性截瘫的一种安全有效的方法。高压氧治疗可加速慢性溃疡创面的愈合，但不能取代溃疡面的局部处理。     

脑出血患者血清胃泌素水平测定及意义

目的探讨血清胃泌素水平与脑出血并发应激性溃疡之间的关系.方法用放免法测定脑出血病人发病后24小时内及恢复期血清胃泌素水平,并与正常人作对照.所获数据用t检验.结果脑出血病人发病后24小时血清胃泌素水平较正常对照组明显增高,合并应激性溃疡出血者升高更显著,恢复期病人血清胃泌素水平与正常对照组相比无显著性差异.结论胃泌素在脑出血并发应激性溃疡的发生中起重要作用.     

PERFORATED PEPTIC ULCER IN THE HUNTER REGION: A REVIEW OF 174 CASES

A review of 174 consecutive patients admitted with a diagnosis of perforated peptic ulcer to eight Hunter Region hospitals during 1979–86 is presented. Among the female admissions, the proportion of patients > 70 years of age was twice that in males. One-third of all perforations were in females who accounted for two-thirds of all perforated gastric ulcers. Multivariate analysis revealed that perforations located in the stomach and older age were both significant independent variables adversely affecting outcome following surgery. In contrast, shock at presentation and delay in operating were not statistically significant independent risk factors.
