面肌痉挛微血管减压术中异常肌反应变化特点与术后疗效关系探究

目的探究面肌痉挛患者微血管减压术(MVD)中异常肌反应(AMR)的变化特点与术后疗效的关系。方法回顾性分析73例MVD术中采用AMR全程定量化监测患者的AMR变化特点,减压操作前AMR阈值较基础阈值升高≥1倍为A1组、1倍为A2组,手术结束时AMR完全消失为B1组、未消失为B2组,B2组中AMR阈值较基础阈值升高≥1倍为B2a组、1倍为B2b组,对各组的术后疗效进行对比分析。结果 A1组21例中,19例立即治愈,1例延迟治愈,1例未愈; A2组52例中,35例立即治愈,9例延迟治愈,8例未愈。A1组较A2组疗效好(P=0. 046)。B1组50例中,42例立即治愈,5例延迟治愈,3例未愈; B2组23例中,12例立即治愈,5例延迟治愈,6例未愈。B1组较B2组疗效好(P=0. 003)。B2 a组的治愈比例较B2 b组高(分别为14/16、3/7),差异有统计学意义(P=0. 045)。结论 AMR在术中的变化特点对术者有重要参考意义,AMR在减压前升高、在手术结束时完全消失、未消失但升高较基础阈值≥1倍者术后疗效相对较好。     

Management of upper gastrointestinal perforations

Perforation of the upper gastrointestinal (UGI) tract is a surgical emergency. Causes of oesophageal perforation include spontaneous (Boerhaave's), iatrogenic or foreign body ingestion. Perforation of the stomach and duodenum is most often caused by peptic ulcer disease. Management involves obtaining an accurate clinical diagnosis, through a combination of patient assessment, imaging and endoscopy. It is important to differentiate intramural from full thickness oesophageal perforations as this will guide the definitive surgical or endoscopic management. Perioperative care of these patients is as important as the definitive management step. This article will summarise an approach to managing perforation of the UGI tract; from initial assessment to postoperative care.     

冠状动脉造影正常的急性心肌梗死患者的临床特点

目的：探讨冠状动脉造影（CAG）正常的急性心肌梗死（AMI）患者的发生机制及临床特点。方法：分析2000年6月至2001年10月86例AMI患者的CAG结果及冠心病相关危险因素。结果：86例中CAG正常者8例，年龄（39＋11．4）（25－52）岁；多无心绞痛史、高血压史、糖尿病史、血脂异常史及家族史；以情绪波动、精神压抑、大量吸烟、饮酒史者居多。结论：冠状动脉痉挛、血栓自溶或溶栓治疗后血栓消失是其主要发生机制；冠状动脉正常的AMI患者其貌似正常，实属高危人群，应高度重视。     

Sildenafil relieves symptoms and normalizes motility in patients with oesophageal spasm: a report of two cases

Oesophageal spasm presents with dysphagia and chest pain. Current treatments are limited by poor efficacy and side effects. Studies in health and oesophageal dysmotility show that sildenafil reduces peristaltic pressure and velocity; however the clinical efficacy and tolerability in symptomatic oesophageal spasm remains uncertain. We provided open-label sildenafil treatment to two patients with severe, treatment resistant symptoms associated with oesophageal spasm. The effects of sildenafil on oesophageal function and symptoms were documented by high resolution manometry (HRM). Patients were followed up to assess the efficacy of maintenance treatment with sildenafil b.i.d. HRM revealed focal and diffuse spasm in the smooth muscle oesophagus that were associated with symptoms in both cases, especially on swallowing solids. Lower oesophageal sphincter function was normal. A therapeutic trial of 25-50 mg sildenafil suppressed oesophageal contraction almost completely for water swallows; however effective, coordinated peristalsis returned with reduced frequency of spasm for solid swallows. Dysphagia and chest pain resolved during the therapeutic trial and efficacy was maintained on maintenance treatment with 25-50 mg sildenafil b.i.d. without troublesome side effects. This report shows that sildenafil can improve oesophageal function and relieve dysphagia and chest pain in patients with oesophageal spasm in whom other treatments have failed.     

臂丛加强化麻醉后并发颈部抽动9例分析

目的探讨臂丛加强化麻醉后颈部抽动的原因及防治。方法对近年来在麻醉方法、用药相同,术后颈部抽动患者的观察治疗过程进行分析。结果臂丛麻醉并发颈部抽动给予充分镇静后可完全治愈。结论麻醉后并发颈部抽动为药物副作用及颈局部刺激的综合作用。     

Review of facial muscle spasms

Facial muscle spasms, which are rare in adults, present a particularly difficult entity for the optometrist to recognise. The condition may not even manifest itself at an eye examination and the optometrist may have to rely on subjective symptoms to assist in the recognition of the condition. It is important to diagnose the condition correctly as specific and effective treatment is available.     

颅神经疾病的肿瘤性病因探讨

目的总结经治的面肌痉挛、三叉神经痛等一类颅神经疾病的肿瘤性病因，对其临床表现特点、发病机制和处理方法进行探讨和分析。方法以面肌痉挛、三又神经痛主诉就诊的患者术前MRI检查发现肿瘤性病因19例，占同期显微手术治疗1032例面肌痉挛、三叉神经痛中的1．8％。其中男7例，女12例。三叉神经痛16例，面肌痉挛3例。术前诊断胆脂瘤8例，脑膜瘤5例，听神经瘤6例。结果肿瘤获全切，病理诊断同术前一致。术后除一例胆脂瘤致三叉神经痛部分缓解外，余症状均消失，平均随访46个月，未见复发。结论颅神经疾病的肿瘤性病因并不少见，在本组三叉神经痛中高达6．3％（16／253）。其临床特点是发病年龄较轻，病程较短，症状较重，三叉神经痛倾向于不典型发作。临床医师应保持警惕，术前应常规MRI检查。一旦发现肿瘤应争取及时手术可获良好效果。     

173例支气管哮喘特异性脱敏治疗的进一步评价

对173例支气管哮喘特异性脱敏治疗的疗效及影响疗效的因素进行了分析。结果表明:显效为30.6%(53/173).有效为56.1%(97/173),无效为13.3%(23/173)。影响疗效的因素与病情的程度有关,而与年龄、病程、皮试阳性反应强弱及脱敏治疗前4个疗程内是否应用曲安缩松等无关。并对特异性脱敏治疗支气管哮喘的优缺点进行讨论。     

芬太尼／哌替啶致Oddi括约肌痉挛的探讨

２００例择期胆囊切除＋术中胆道造影患者分二组；芬太尼１７ｕｇ／ｋｇ静注（Ｆ组，ｎ＝１００）、哌替啶１ｍｇ／ｋｇ静注。评价两种麻醉性镇痛药致Ｏｄｄｉ括约肌痉挛的发生率，结果：８例病人造影剂不能通过Ｏｄｄｉ括约肌、十二指肠不显影，胆总管下端显示“鸟嘴样”或“假结石”影像，后者３例病人胆总管探查阴性，静注纳络酮０．４ｍｇ后，全部病例造影剂顺利进入十二指肠。结论：硬膜外麻醉辅用小剂量芬太尼／哌替啶时Ｏｄｄ
