目的:分析针刀与针灸配合应用于腰椎间盘突出症患者中的临床治疗效果。方法:在我院针灸康复科2017年12月-2018年12月治疗的腰椎间盘突出症患者中选取64例,并严格按照系统随机分配原则分为对照组和观察组,各32例。其中对照组采用针灸进行治疗,观察组采用针刀与针灸配合治疗,观察对比两组患者治疗后临床效果和治疗前后运动功能评分(Fugl-Meyer)、腰椎日本骨科学会(Japanese Orthopaedic Association,JOA)评分、视觉模拟评分法(Visual Analogue Scale,VAS)评分以及临床症状改善情况。结果:两组患者治疗前Fugl-Meyer、VAS、JOA评分差异无统计学意义(P>0.05),治疗后对照组VAS评分高于观察组,Fugl-Meyer、JOA评分低于观察组,且对照组总有效率低于观察组,对照组腰骶疼痛评分和腿疼痛评分均低于观察组,直腿抬高度高于观察组,差异具有统计学意义(P<0.05)。结论:予以腰椎间盘突出症患者针刀与针灸配合治疗效果显著,效果优于单一使用针灸治疗,可有效缓解患者疼痛感,改善临床症状,值得推广。 相似文献

Summary We present a case of blindness and Anton’s syndrome in a psychiatric patient with late diagnosis of a giant frontal meningioma.
The criteria for advanced diagnostic imaging in the psychiatric population are discussed. We conclude that MR or CT scan is
indicated in psychiatric in-patients who fail to improve with standard psychiatric treatment. This strategy should be submitted
to a cost-benefit analysis. 相似文献

Intraductal papillary mucinous tumor (IPMT) of the pancreas is characterized by slow growth and a relatively favorable prognosis, however, invasive cancer originating in an IPMT is associated with a poor prognosis. Although various parameters in imaging modalities have been advocated to differentiate between benign IPMN and malignant ones, it is not easy to obtain definite diagnosis based on these parameters. Peroral pancreatoscopy (POPS) allows a clear and direct visualization of the pancreatic duct, providing useful information regarding tumor nature in IPMT. The authors have studied the usefulness of POPS in the diagnosis of IPMT. Nevertheless, its usefulness is not necessarily widely accepted and the significance of POPS is still controversial. In this review, the authors intended to address the diagnostic value of POPS and to clarify its role in the diagnosis of IPMT. The authors think treatment of IPMT can be improved by introducing POPS because the determination of surgical procedure as well as the area of resection based on the preoperative diagnosis of the involvement of the main pancreatic duct and branch duct is inevitable. 相似文献

目的:观察米索前列醇预防剖宫产手术后出血的临床效果。方法:随机将有剖宫产手术指征的344例孕妇分为3组,分别为在胎儿娩出后给予米索前列醇200mg舌下含化(A组)、缩宫素静脉滴注及子宫肌层注射(B组)和对照组(C组,不给予任何药物),观察产后不同时间的出血量。结果:产后出血量及出血发生率A、B组均明显少于C组(P<0·05)。结论:米索前列醇对分娩后子宫具有较好的收缩作用,且给药方便、安全性较好。 相似文献

We developed a self-administered questionnaire for screening the most common adult-onset dystonias. It was tested in 90 first-degree relatives of 22 adult-onset dystonia patients, yielding 79% sensitivity and 94% specificity. Simulation of a case-finding procedure based on serial application of the questionnaire and clinical examination of both subjects screening positive and subjects screening negative who had < 8 years of schooling increased sensitivity to 95% and specificity to 100%. This questionnaire may be an important screening resource for familial aggregation studies to be used in the context of a complex case-finding procedure. 相似文献

BACKGROUND: The recurrent chronic orofacial swelling caused by orofacial granulomatosis (OFG) can cause significant cosmetic and functional problems but can be prevented if the disease is diagnosed early and promptly treated. Although the enlargement of the lips is described to be the most common presenting complaint, the clinical onset of OFG may be characterized by minor associated mucosal and neurological manifestations, making early diagnosis very difficult or, sometimes, merely presumable. PATIENTS AND METHODS: We retrospectively analyzed the clinical manifestations of 19 patients with OFG, who were examined at our institution between 1998 and 2002, in order to determine their initial manifestations and presenting symptoms. RESULTS: A total of 10 patients showed classical recurrent enlargement of the lips (six lower; four upper) as presenting symptom. In the other nine patients, OFG onset was characterized by transient unilateral facial nerve palsy (two cases), intraoral manifestations (two cases), recurrent swelling of the periorbital area (two cases), of the chin (one case), of the zygomatic area (one case), and of the cheeks (one case). CONCLUSION: Our data underlined that OFG onset could be frequently characterized by widely variable, multiform, and temporary clinical findings. Involvement of atypical sites of the orofacial region and presence of single minor manifestations may occur as presenting symptoms, often preceding the development of traditional clinical findings. 相似文献
