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.     

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     

维拉帕米灌注治疗前列腺术后膀胱痉挛性疼痛的临床疗效观察

应用改进封闭脊髓窗技术活体观察脊髓损伤后脊髓微循环变化

目的:探讨应用改进的封闭脊髓窗技术活体观察大鼠脊髓损伤后脊髓微循环变化的可行性及效果.方法:改进传统的脊髓窗,设计带有打击探头的脊髓窗.45只SD大鼠随机分为对照组(n=20)和实验组(n=25).实验组大鼠脊髓窗安装完成后进行窗内打击脊髓,然后即时观察并记录打击后2h内打击点周围微动脉直径的变化.对照组大鼠在脊髓窗安装完成后不进行打击,只对脊髓微动脉直径进行连续2h观察并记录.术后两组大鼠进行BBB运动功能评分,处死动物取脊髓标本切片,HE染色,观察脊髓组织改变情况.结果:实验组大鼠打击点周围2～6mm的微动脉直径在打击后10min、30min、1h、2h各时间点均较打击前明显减小,术后2d及7d时BBB功能评分明显低于术前,病理切片可见脊髓打击区神经组织变性液化.对照组大鼠在观测开始及结束时脊髓微动脉直径无明显变化,术后BBB评分与术前BBB评分均为21分,病理切片未见脊髓损伤表现.结论:改进的封闭脊髓窗技术可以有效地实现窗内打击脊髓,并可以安全地对脊髓表面微血管进行活体观测.脊髓表面打击点周围2～6mm的微动脉在脊髓损伤后10min即发生痉挛.     

Fatal encephalitis in a patient with refractory celiac disease presenting with myorhythmia and carpal spasm.

We report the case of a woman with refractory celiac disease who developed abnormal spontaneous movements of the extremities and face consistent with myorhythmia. Investigation led to a diagnosis of encephalitis, confirmed by postmortem examination. The movements were likely caused by nonparaneoplastic encephalitis associated with refractory celiac disease. Etiologic and diagnostic considerations and treatment options are discussed.
