病毒唑雾化吸入治疗上呼吸道感染临床疗效观察

选择89年2月至90年2月175例上呼吸道感染患儿,分为病毒唑雾化吸入组(61例).病毒唑全身给药组(53例)和对照组(61例).平均退热时间分别为30.01±.11,31.89±9.28,40.57±16.94小时.病毒唑组与对照组有非常显著性差异(p<0.01)但两病毒唑治疗组之间无显著性差异,并发现发病时间在一天内接受治疗者,退热时间明显短于超过一天之病例,且发病两天后治疗者与对照组已无显著差异(p<0.05).病毒唑全身用药组和对照组共有4例发展为支气管炎和肺炎,而雾化吸入组无,说明该治疗方法可以阻止病毒感染蔓延至下呼吸道.     

金属支架植入治疗上尿路闭锁的中期结果

目的评价金属支架植入治疗上尿路闭锁的中期疗效。方法1995年10月至1998年12月，采用金属支架永久植入治疗上尿路闭锁患者13例，其中肾盂输尿管连接部闭锁8例，肾下盏输尿管吻合口闭锁3例，输尿管上段闭锁和输尿管膀膀吻合口闭锁各1例。闭锁长度1．0～3．6cm。采用影像学方法定期随访，必要时行输尿管镜检查。结果13例术后随访1～9年，平均92个月。输尿管引流通畅6例，需辅助停留输尿管内支架管、换管时见支架处上皮覆盖完全3例，因肾功能进行性恶化而行肾切除2例，因肾积脓感染无法控制而取出金属支架2例。3例患者分别于置管后4、6、6个月发现支架内肉芽组织生长，用钬激光汽化肉芽组织。其中1例4个月后又出现肉芽组织生长，再用钬激光汽化后长期留置双J管。2例患者于置管术后28、32个月并发支架近端结石，分别用微创经皮取石术和输尿管镜取出。结论金属支架植入治疗上尿路闭锁安全、有效，中期结果满意，其对上尿路动力学的影响尚需进一步研究。     

髂骨截骨延长术下肢延长量计算方法的探讨

髂骨截骨延长术下肢的延长量及其测算方法报道不一。根据手术的生物力学原理和肢体延长的机理,认为肢体的延长量是由患肢绝对延长和相对延长两部分组成的,它与髂骨截骨间距密切相关,经数学推算,其方法为测量X线片髂骨截骨撑开的梯形中心间距(cm),减去X线片的放大值(cm)再除以0.7;手术时髂骨需要撑开的宽度(cm)为肢体短缩数(cm)乘以0.7。经临床103例手术验证,这种计算方法是准确的。     

MRI and SPECT findings in amyotrophic lateral sclerosis

Summary MRI was performed in 21 patients and single photon emission computed tomography (SPECT) withN-isopropyl-p-¹²³I iodoamphetamine in 16 patients, to visualize upper motor neurone lesions in amyotrophic lateral sclerosis. T2-weighted MRI revealed high signal along the course of the pyramidal tract in the internal capsule and cerebral peduncle in 4 of 21 patients. SPECT images were normal in 4 patients, but uptake was reduced in the cerebral cortex that includes the motor area in 11.     

Long-term Outcomes of Patients Undergoing War-related Amputations of the Foot and Ankle

Long-term clinical and functional outcomes for patients undergoing foot and ankle amputations are not well documented. We attempted to document long-term outcomes for patients who required lower extremity amputations as a result of wounds suffered during wartime. For this study, 27 Iranian soldiers who had wounds requiring amputation of the foot and ankle were selected for follow-up. The participants' wartime medical records were reviewed, a clinical examination was performed, and each participant completed a questionnaire. Postamputation follow-up averaged 17.5 years. The most prevalent (66.6%) cause of injury was a land mine. The prevalences of different clinical symptoms reported by the amputees at the time of the last follow-up were as follows: 11 (40.7%) with phantom sensation, 6 (22.2%) with phantom pain, 12 (44.4%) with stump pain, 12 (44.4%) with back pain, 9 (33.3%) with contralateral knee pain, and 4 (14.8%) with ipsilateral knee pain; 20 (74%) reported treatment for psychological conditions. In regard to social conditions, 13 (48.1) were currently employed, or had been employed, for a number of years after the amputation; 26 (96%) had children, and all of the patients were married. The results of this observational study indicate that individuals have significant long-term pain and discomfort after war-related lower extremity amputation. Although all 27 (100%) of the amputees were able to maintain satisfactory family functioning, only 13 (48.1%) of the study participants were able to remain productively employed after undergoing amputation, and 20 (74%) reported long-term psychological problems in addition to their physical pain.

Percutaneous Transhepatic Cholangiodrainage as Rescue Therapy for Symptomatic Biliary Leakage Without Biliary Tract Dilation After Major Surgery

Symptomatic biliary leakage following major upper abdominal surgery is a severe complication resulting in increased morbidity and mortality. Treatment options usually include either endoscopic intervention or surgical revision. These options may be burdened by a high perioperative risk for the patient (e.g., patients with severe disease) or simply may not be possible (e.g., nonpreserved gastroduodenal passage). In the past, percutaneous transhepatic cholangiodrainage did only seem to be a viable option for patients with dilated bile ducts. Here, we present our experience in a consecutive series of patients with symptomatic biliary leakage following major upper abdominal surgery and without dilation of the biliary system that underwent percutaneous transhepatic cholangiodrainage. Percutaneous transhepatic cholangiodrainage was feasible in 15 of 18 patients (83.3%). The procedure was technically not possible in three patients (16.7%). In 10 of the 15 patients (66.6%) with feasible percutaneous transhepatic cholangiodrainage, biliary leakage was definitely controlled without the need for surgical revision. Depending on the experience with the interventional procedure, percutaneous transhepatic cholangiodrainage should be considered as an alternative for treatment of symptomatic biliary leakage instead of immediate reoperation.

上肢屈曲性旋转撕脱离断伤的形成及功能挽救

目的探讨上肢轴向屈曲性旋转撕脱离断伤的形成以及侧胸和背部组织在功能挽救中的应用方式和疗效。方法2000年7月～2003年9月共收治6例上肢轴向屈曲性旋转撕脱离断伤患者,所有病例行一期再植或寄养再植。术后肩关节外展90°、肘关节屈曲100°位石膏或支具固定,6周后去除固定行功能锻炼。结果6例患者再植均顺利成活,随访3个月～2年,术后肩关节外展50°～90°,前屈50°～70°,后伸20°～30°,内收20°～40°;肘关节屈曲100°～140°,伸-20°～0°;重建术后3个月时屈肘肌力达Ⅳ～Ⅴ级。结论充分利用侧胸和背部组织特点进行分期、分层手术,解决创面覆盖和功能重建互相干扰的矛盾,是挽救严重轴向屈曲性旋转撕脱离断伤上肢,恢复其外形和功能的可靠方法。     

颈段、胸上段食管癌的外科治疗

目的总结外科手术治疗颈段、胸上段食管癌（肿瘤上极距胸廓入口下方≤3cm）的临床经验,以提高手术疗效,减少术后并发症的发生。方法回顾性分析我院收治的142例颈段、胸上段食管癌患者的临床资料,其中行食管癌根治术122例,姑息切除术15例,总手术切除率为96.5%,探查术5例。主要重建手术术式包括：单纯剥脱胃代食管术、结肠代食管术、空肠代食管术、胸大肌皮瓣重建术;右胸-上腹-颈三切口胃代食管术、全喉切除＋胃代食管术、管胃代食管术,左胸-颈两切口、胃代食管术。结果住院死亡5例,其中2例死于肺部感染,1例结肠坏死致严重感染,1例姑息切除后胃气管漏致肺部感染,1例胃大量反流误吸。9例患者食管上切端发现癌残留。8例颈段食管癌和21例胸上段食管癌患者术后发生并发症,主要包括空肠坏死、结肠坏死、喉返神经损伤、肺部感染、吞咽功能障碍、食管反流。随访117例,随访率85.4%（117/137）,随访时间1～5年;失访20例。术后1、3、5年生存率分别为72%,48%和31%。Ⅰ、Ⅱ、Ⅲ、Ⅳa期患者的5年生存率分别为82.3%,61.2%,25.0%和5.0%。结论颈段和肿瘤上极距胸廓入口下方≤3cm的胸上段食管癌患者的手术治疗在手术方式、切除范围、术后并发症的防治、术后功能保留和恢复等方面尚需进一步探讨。     

上尿路梗阻性急性肾功能不全内、外引流的选择

目的探讨内、外引流在上尿路梗阻急性肾功能不全时的选择和效果。方法25例各种原因引起的上尿路梗阻（15例肿瘤性梗阻,10例非肿瘤性梗阻）合并急性肾功能不全,分别或先后对12例行输尿管内置双J管（doub le J,D J）内引流15次,对19例行经皮肾穿刺造瘘（percutaneous nephrectomy,PCN）外引流23次。结果引流成功23例,PCN外引流成功率86.9%（20/23）,双J管内引流成功率60.0%（9/15）,PCN术后继发出血1例。结论对于盆腹腔进展期或广泛转移肿瘤导致的梗阻,PCN解除梗阻优于输尿管支架内引流;非肿瘤性梗阻宜先尝试D J内引流。
