Chronic orchialgia: Consider gabapentin or nortriptyline before considering surgery

OBJECTIVE: To establish if there is a role for gabapentin or nortriptyline in the treatment of chronic orchialgia. METHODS: Twenty-six consecutive patients with chronic orchialgia were seen in the chronic pain clinic by a multidisciplinary team. A pain questionnaire was completed prior to commencing either gabapentin or nortriptyline. They were reviewed at 3 months and a repeat questionnaire completed. A 50% improvement in pain was considered successful. RESULTS: Complete data was available for 19 patients. Overall, 61.5% of patients commenced on gabapentin and 66.6% of patients commenced on nortriptyline had a greater than 50% improvement in pain. Patients with post-vasectomy testicular pain were considered as a subgroup. None of these patients had a greater than 50% improvement in pain. However, 80% of patients in the subgroup with idiopathic chronic orchialgia had a greater than 50% improvement in pain. CONCLUSION: Although this is a small study, it appears that gabapentin and nortriptyline are effective in the treatment of idiopathic chronic orchialgia but not post-vasectomy pain.     

小脑后下动脉动脉瘤的诊断和治疗

目的探讨小脑后下动脉动脉瘤的临床特征、诊断、鉴别诊断和治疗。方法回顾性分析12例小脑后下动脉瘤的临床表现、影像学特征、手术效果及诊治过程中存在的相关问题。结果12例中有11例因动脉瘤破裂出血而发病,单纯第四脑室出血4例,全脑室系统出血2例,小脑半球出血3例,小脑蚓部伴第四脑室出血1例,侧脑室伴第三脑室出血1例,以后颅窝占位病变表现1例。8例术前行DSA检查明确诊断,4例术中明确诊断。12例均行后颅窝开颅显微手术治疗,其中动脉瘤颈夹闭9例,孤立切除2例,动脉瘤加固术1例,术后2例因脑积水加重行脑室-腹腔分流术。12例中除1例术后留有轻偏瘫外,其余11例恢复良好。结论小脑后下动脉瘤多以第四脑室出血发病,少数以小脑半球或蚓部出血发病,及早治疗效果满意。手术方式应尽量夹闭动脉瘤颈,对于小脑后下动脉末端动脉瘤,可以采用孤立切除术。     

系统性健康教育对改善焦虑病人症状的影响

焦虑症是以焦虑、紧张、恐惧等情绪障碍为主,常伴有自主神经系统症状和运动性不安等[1].主要表现为惊恐发作和广泛性焦虑两种形式.随着社会的发展、生活节奏的加快、竞争的激烈、社会分工的多元化、婚姻的变故、考试的不理想等生活事件,使人们的精神压力大为增加[2].以往的传统求稳心态已落后于时代的发展,一种以焦虑情绪为主的神经症已成为一个时代的现代疾病.焦虑症的发展有逐年上升的趋势,已受到更多人的关注和注意.对焦虑症病人实施系统性的健康教育,降低焦虑症的复发率具有重要的意义.……     

Goldenhar 综合征家系的临床表型和遗传学分析

目的分析1组Goldenhar综合征家系的临床表现及遗传学特征。方法我们随访到1组4代33人的Goldenhar综合征家系，对目前存活的29人进行了临床表型和遗传学的初步分析。结果家系内有Goldenhaar综合征患者5人．临床表现具高度多样性，累及眼、耳、脊柱、颜面、口腔等多个器官和系统的发育不良，在遗传方式上属于常染色体显性遗传。从细胞遗传学水平对家系中成员进行染色体检查，未发现核型异常。结论该Goldenhar综合征家系属常染色体显性遗传，染色体检查未发现核型异常。     

有机锗对环磷酸胺抗移植肝癌作用的影响

用有机锗（Ge－132）试验治疗荷移植肝癌小鼠。结果：De－132高剂量（12．5mg/次）治疗组的抑癌率为用31．0％，移植肝癌白细胞（WBC）浸润（＋＋＋）占72．7％、血清超氧化物歧化酶（SOD）活性为121Nu／ml，而生理盐水对照治疗组相应的后两项指标分别为用36．4％及81Nu／ml，两组比较有显著性差异（P＜0．05）；环磷酰胺（CTX）治疗组的抑癌率为37.0％，癌体WBC浸润（＋＋＋）为27.3％，血清SOD活性为102Nu／ml；ge-132高剂量与CTX2联合治疗组的抑癌率为45．0％，癌体WBC浸润（＋＋＋）为54．5％，血清SOD活性为142Nu/ml，两组比较，后二项指标有显著性差异（P＜0．05）。由此提示Ge-132高剂量能明显增强荷移植肝癌小鼠的细胞免疫及血清SOD活性，并有一定的抗移植肝癌作用。     

Cat-301 immunoreactivity in the lateral geniculate nucleus and visual cortex of the strabismic amblyopic cat

Purpose: It was investigated whether alterations in neuronal structure and function occasioned by strabismic amblyopia also may be reflected in alterations in the expression on Y type neurons of a Cat-301 antibody sensitive antigen in the lateral geniculate nucleus (LGN) and cortex of our cat model of strabismic amblyopia. Methods/Results: The percentage of positively labelled cells was reduced in LGN laminae that received input from the deviated eye in strabismic amblyopic cats compared with normal cats. In the strabismic cortex, the density of immunopositive neurons was significantly reduced compared with normal, the effect being most pronounced in layer IV Conclusions: Despite previous physiological recordings indicating a decrease in X-cell associated acuity in strabismic amblyopia, the present findings imply that the changes in the early visual experience occasioned by strabismus also produce specific molecular changes in theY neuronal class.     

Localised endosteal bone lysis in relation to the femoral components of cemented total hip arthroplasties

Four cases are described of localised endosteal bone lysis in the femur occurring in association with cemented femoral components that were not obviously 'loose' radiologically. In each, the area of lysis was shown at operation to be related directly to a region in which there was a local defect in the cement mantle surrounding the stem. Via the space between the stem and cement, such defects provide a route through which the contents of the joint cavity may reach the endosteal surface of the femur, subsequently leading to localised bone lysis, and later to frank loosening.     

神经移位修复臂丛神经根性撕脱伤

１９８７年７月～１９９４年６月，对２１例臂丛神经根性撕脱伤采用神经移位修复。其中复合移位４组神经（膈神经、副神经、颈丛运动支、肋间神经）者１例，３组（膈神经、副神经、颈丛运动支）者６例，２组（膈神经、副神经）者９例，１组（膈神经或颈丛运动支或肋间神经）者５例。术中发现臂丛神经变异１例，对４例合并锁骨下动脉损伤者，在神经移位的同时进行血管修复，促进患肢的血液循环，有利于神经的康复。随访到１９例，随访时间为８个月～６年２个月，优良率达７３．７％。认为，神经移位术是修复神经根性撕裂伤的常规方法，合并血管损伤者也应同时修复，对促进神经功能恢复有利     

高渗盐液和抗休克裤合并应用对大鼠早期休克的影响

采用高渗盐液，抗休克裤及两者联用纠正大鼠早期失血性休克。结果显示，单独使用ＡＳＴ，仅见动脉血压短时间回升，而单用ＨＴＳ，血压则明显回升。若先用ＡＳＴ，再注入ＨＴＳ，也能取得明显效果。失血休克大鼠血浆纤维连接蛋白水平显著降低，各组之间均无差异血浆脂质过氧化物－丙二醛的含量明显增加，且在ＨＴＳ组，ＨＴＳ＋ＡＳＴ组与ＮＳ对照组之间有显著差异。
