半导体激光穴位照射与药物治疗急慢性关节损伤的疗效比较

目的探讨低功率半导体激光对急慢性关节损伤的治疗作用.方法1999年至2004年急慢性关节损伤的患者240例,随机分为两组,各120例,激光组采用低功率半导体激光治疗仪照射痛点;对照组口服活血止痛胶囊,外用沈阳红药膏治疗.结果两周后的疗效比较.激光组有效率为85.0%,痊愈率为44.2%;对照组有效率为71.7%,痊愈率为20.8%;差异有显著意义.激光组中,急性关节损伤的患者痊愈率为52.9%,慢性关节损伤患者的痊愈率为32.7%,差异有显著意义(P＜0.05)有效率,差异无显著性意义.结论低功率半导体激光对急慢性关节损伤,尤其是急性小关节损伤有很好的疗效.     

Crohn病的CT表现

目的探讨Crohn病的CT表现特点。方法回顾性分析经病理证实的18例Crohn病的CT征象，大多数病例采用螺旋CT或多层螺旋CT扫描。结果所有病例均有节段性肠壁增厚，CT增强有7例表现为肠壁均匀增厚，缺乏层次，同时肠壁强化不明显；有11例表现为黏膜增厚和分层形成“靶征”和“双环征”，肠壁厚度多在5～10mm；有9例表现为病变段肠管周围纤维脂肪成分增多，蜂窝织炎及肠周或肠系膜血管增多增粗。有5例CT首先考虑为其他疾病，1例考虑为闭攀性肠梗阻，1例首先考虑为肠结核，2例回盲部病变怀疑为癌，1例肠穿孔形成脓肿仅诊为化脓性感染。结论cT不但能准确显示Crohn病肠壁、肠系膜及周围结构的异常，增强CT还能区分活动性与非活动性病变，有助于临床采取合理而积极的治疗方案。     

从近两年132例青少年心理咨询得到的启示

目的 了解青少年学生的心理问题和心理障碍，以及对其进行心理咨询的重要意义。方法 从门诊详细记录的案例进行统计分析。结果 132例青少年学生采访者的心理问题和心理障碍占前四位的是：学习问题（占74．2％）、行为问题（占18．9％）、青春期适应不良（占15．9％）和人际关系问题（占7．6％）。还有2人是偏执性精神病（占1.5％）。结论 对青少年学生进行心理咨询很有必要，来访者有咨询动机很重要，重视第一次会谈，同理心的重要作用，明确诊断，做好记录，寻找主题和切入点，折衷整合治疗是必然的趋势。     

Laparoscopic repair of a perforated marginal ulcer 2 years after gastric bypass

The authors present the case of a 43-year-old women who underwent a laparoscopic gastric bypass in 2003 for morbid obesity. They report that 2 years later, she had maintained significant weight loss, but had developed acute abdominal pain, followed by nausea and emesis. In the emergency room, she had diffuse tenderness, tachycardia, and leukocytosis. After initial resuscitation, a computed tomography was performed, which showed free air above the liver and thickened small bowel loops. She was brought emergently to the operating room for laparoscopy. At surgery, turbid fluid and inflamed small bowel loops were seen. A perforated marginal ulcer was discovered in the Roux limb, approximately 2 cm distal to the gastrojejunal anastomosis. The perforation was oversewn primarily and patched with omentum. The repair was tested by intraoperative endoscopy. A gastrostomy tube also was placed within the gastric remnant for enteral access. The patient did extremely well postoperatively, and had an uneventful postoperative course. She was discharged on postoperative day 4. The gastrostomy tube was removed at 1 month, and at this writing, she remains well since surgery. An upper endoscopy at 2 months was completely normal, and the Helicobacter pylori test results were negative. The gastric pouch had not significantly enlarged since initial surgery, as indicated by both endoscopy and barium study. Marginal ulcer is reported to be 0.6% to 16% after laparoscopic gastric bypass [1]. Etiologies include gastrogastric fistula, excessively large gastric pouch containing antral mucosa, H. pylori infection, nonsteroidal antiinflammatory use, and smoking [2]. Unfortunately, none of these applied to the reported patient. Because her exact etiology remains unknown, she at this writing continues to receive proton pump inhibitor therapy.
