Mucosal features and granulocyte–monocyte-apheresis in steroid-dependent/refractory ulcerative colitis

BACKGROUND: Mucosa-infiltrated granulocyte neutrophils are an early characteristic of inflammation and the main histological feature of active ulcerative colitis. Mucosal healing has recently been indicated as an important tool in the evaluation of response to treatment. While several studies have stressed the efficacy of granulocyte-monocyte-apheresis in inducing clinical remission in active ulcerative colitis, few data are available on mucosal features. AIM: Aim of this study was to assess the effects of granulocyte-monocyte-apheresis on clinical and mucosal features in patients with ulcerative colitis, dependent upon or refractory to steroids. MATERIAL AND METHODS: From April 2004 to April 2005, 12 patients (5 females, 7 males, mean age 49 years, range 33-71 years), with mild-moderate ulcerative colitis (six left colitis, six pancolitis) dependent/refractory upon steroids were enrolled. Each patient was treated for a 5-week period with five cycles of granulocyte-monocyte-apheresis. Patients were evaluated at baseline and 1 week after the last apheresis by means of Global Physician Assessment, quality of life features, laboratory tests (erythrocyte sedimentation rate, CRP, full blood count, faecal calprotectine), endoscopy and histology. RESULTS: At week 6 of follow-up, complete mucosal healing was observed in 3 out of 12 patients, partial mucosal healing in 8 patients and no change in 1 patient. Clinical response was complete in 8 out of 12 patients. CONCLUSIONS: These data suggest that granulocyte-monocyte-apheresis induces an improvement both in clinical and mucosal lesions in steroid-dependent/refractory ulcerative colitis. Of note, the reduction in granulocyte infiltration and the improvement in mucosal lesions are accompanied by a reduction in faecal calprotectine.     

炎症性肠病危险因素的流行病学调查研究

目的通过病例调查，筛选IBD的危险因素。方法采用问卷方式，对72例确诊IBD患者及72例配对的健康个体调查，对结果进行COX回归分析，筛选出IBD的致病危险因素。结果COX回归分析提示紧张度、牛奶和油炸食品在IBD致病因素中具有统计学意义。结论紧张度、牛奶和油炸食品可能是IBD的致病危险因素。     

腹泻型、便秘型肠易激综合征和功能性便秘患者的直肠肛管测压比较

目的研究腹泻型、便秘型IBS和功能性便秘患者直肠肛管测压参数的不同，并评价性别和年龄对各项参数的影响，方法腹泻型IBS(n=18)、便秘型IBS(n=14)、功能性便秘(n=30)和健康对照组(n=18)，通过定点牵拉法进行直肠肛管测压。结果腹泻型IBS、便秘型IBS、功能性便秘以及健康对照组直肠肛管测压各项压力参数基本无差异，但三组患者的诱发RAIR所需的最小气体容量均显著高于健康对照组，便秘型IBS和功能性便秘模拟排便时发生矛盾运动的百分比显著高于腹泻型IBS和健康对照组；便秘型IBS和功能性便秘组中，肛管上部和下部最大紧缩压力，以及模拟排便发生矛盾运动的百分比男性均高于女性；腹泻型IBS组内男性模拟排便发生矛盾运动的百分比高于女性；健康对照组内男性肛管下部静息压力和最大紧缩压力高于女性；各组20-50岁人群和50-80岁人群的各项压力参数无显著性差异，但功能性便秘组青年组诱发RAIR所需的最小气体容量低于老年组。结论腹泻型IBS、便秘型IBS和功能性便秘患者的直肠肛管测压各项压力参数无助于这三型功能性肠病的鉴别诊断。男性的直肠肛管测压的多项压力参数显著高于女性，男性更易出现模拟排便矛盾运动，年龄对直肠肛管测压各项参数无明显影响。     

对大肠癌术后早期炎性肠梗阻诊治的探讨

目的：探讨大肠癌术后早期炎性肠梗阻的特点及治疗方法；方法：分析10例大肠癌术后出现早期炎性肠梗阻的临床表现并进行综合保守治疗；结果：10例患者保守治疗全部成功；结论：术后早期炎性肠梗阻是一种非细菌性炎性肠梗阻，以发生在术后早期，腹胀、呕吐明显，腹痛轻或无为主要临床特点，治疗应采用保守治疗。     

负压引流在小切口根治腋臭术中的应用

目的:在众多腋臭治疗方法中,探索出一种能有效根治腋臭且并发症少的治疗方案。方法:利用小切口,肿胀麻醉,把带有汗腺及毛囊的皮肤修剪薄至全厚及中厚皮片厚度,术毕放置负压引流,使皮肤与基底贴合良好,并加压包扎。结果:本法共治疗32例腋臭患者,其中其他方法治疗复发者11例。除2例术后有轻微气味外,其余均得到根治,术后瘢痕不明显。结论:负压引流在小切口根治腋臭中可有效减少并发症,提高治愈率。     

超声乳化白内障摘除手术中小瞳孔的处理

目的探讨小瞳孔白内障的手术方法、效果、并发症及其处理.方法本组对近5年来完成的188例由于炎症、抗青光眼手术以后、外伤、糖尿病等引起的小瞳孔白内障病人进行回顾性分析.本组病人均采用超声乳化摘除法,手术中没有用辅助的扩瞳器,采用的是人工机械性扩大瞳孔,超声乳化的技巧是弹性法和劈裂法.结果手术后病人的瞳孔都有不同程度的扩大,但一般都不大于5mm且成规则状.有半数病人有不同程度的手术后角膜水肿,1周后自行恢复;极个别的病人角膜水肿恢复时间比较长,但未发现角膜失代偿.还有少数病人有后囊破裂,悬韧带断裂,玻璃体脱出.结论对于有经验的医师超声乳化手术在小瞳孔白内障的处理是安全有效的,可以获得如同正常瞳孔的白内障相同的效果.     

The Relationship Between Daily Life Stress and Gastrointestinal Symptoms in Women with Irritable Bowel Syndrome

Research on irritable bowel syndrome (IBS), a functional disorder of the gastrointestinal (GI) system, has linked GI symptoms to stress. This study examined the relationship between daily stress and GI symptoms across women and within woman in IBS patients (n = 26), IBS nonpatients (IBS-NP; n = 23), and controls (n = 26), controlling for menstrual cycle phase. Women (ages 20–45) completed daily health diaries for two cycles in which they monitored daily GI symptoms and stress levels. The Life Event Survey (LES) was used as a retrospective measure of self-reported stress. The across-women analyses showed higher mean GI symptoms and stress in the IBS and IBS-NP groups relative to controls but no group differences in LES scores. The within-woman analyses found a significant and positive relationship between daily stress and daily symptoms in both the IBS-NP and the IBS groups. Controlling for menstrual cycle had no substantial impact on the results.     

Laparoscopic-assisted bowel surgery

The use of laparoscopic surgical techniques is now being applied to a variety of operations traditionally performed in an open fashion. Twenty patients underwent laparoscopic-guided large and small bowel surgery at our institution from March 1991 to April 1992. The indications for surgery included polyps, obstruction, bleeding, and perforation, and pathologic diagnoses included benign polyps, lipomas, inflammatory bowel disease, perforation of a jejunal diverticulum, colonic arteriovenous malformations, and adenocarcinoma. Mobilization of the colon, ligation of the mesentery, and closure of the mesenteric defect were performed using the laparoscopic equipment. One trocar site was enlarged to 3 cm to deliver the bowel through the abdominal wall. All anastomoses were hand-sewn. Postoperative hospitalization ranged from 2 to 31 days (median, five days). No mortality was noted, and morbidity was 20 percent. We conclude that laparoscopic-guided bowel surgery is technically feasible and should translate into shorter hospitalization and less patient discomfort.
