Botulinum toxin and neuromotor rehabilitation: An integrated approach to idiopathic cervical dystonia.

Currently, the best treatment option for idiopathic cervical dystonia (ICD) is injection of botulinum toxin (BTX) into the affected muscles, whereas rehabilitative approaches have given disappointing results. We evaluated whether the association of an ad hoc rehabilitative program may improve the clinical efficacy of BTX treatment in a single-center, cross-over, controlled study. Forty patients with ICD were randomly assigned to two different treatment groups: (1) BTX type A (BTX-A) plus a specific program of physical therapy (BTX-PT) or (2) BTX-A alone (BTX-0). Patients in the BTX-PT group showed a longer duration of the clinical benefit (118.8 vs. 99.1 days) and needed a lower dose of BTX at reinjection (284.5 vs. 325.5 units). In addition, they showed more marked reductions in their disability in activities of daily living (-9.7 vs. -4.85 points) and subjective pain (-13.35 vs. 6.95 points) scores. Association of BTX-A therapy with a specific program of physical therapy may improve ICD treatment outcome.     

The outcome of ganglion clipping in hyperhidrosis and blushing

A total of 114 patients with various sympathetic disorders underwent endoscopic sympathetic block over different thoracic ganglions by the clipping method. The advantages of this method include the recognition of the clipped level, changeability, and reversibility. However, 4.4% of patients were unilaterally clipped at the wrong level.     

改进微波幅射器探头治疗宫颈糜烂疗效观察

目的：探讨改进的微波辐射器探头治疗宫颈糜烂的疗效。方法：将微波辐射器探头由双直线形、双针形、单针形等点线状改进成为“单舌形”和“双舌形”两种弧形平面探头，用于治疗宫颈糜烂。分析1999-2002年450例宫颈糜烂治疗资料，其中300例经微波治疗(A组)，150例经C02—激光治疗(B组)，随访1—3个月。结果：两组治疗后3个月内A组治愈率明显高于B组(P＜0．005)，总有效率A组明显高于B组(P＜0．025)。两组术中、术后不良反应比较：术中宫颈创面出血A组明显低于B组(P＜0．005)，术中腹痛、脱痂期出血量、术后局部感染率方面两组相似。结论：所改进的微波辐射器探头治疗宫颈糜烂治愈率高，操作安全，术后并发症少，医患乐于接受。     

Dysfunction of the pupillary light reflex following migraine headache

Using pupillometry and sympathetic skin responses we compared the changes in local and systemic autonomic function within one week of a migraine attack. We investigated whether the measurement of the pupillary light reflex provides further information on the pathophysiology of migraine. Forty-two migraine patients and forty-two healthy age-matched controls were included. The parameters that were measured were the amplitude of the pupillary light reflex, the pupil size at the beginning of the measurement, the latency, the velocity of constriction and the velocity at the end of the dilatation. The average pupil size was 6.43 mm in the migraine group and 6.7 mm in the control group (p < 0.01). Reduced velocity of constriction and smaller amplitude of constriction in migraine patients within two days of an attack were signs of a parasympathetic dysfunction (p < 0.05). The sympathetic skin response did not differ significantly between migraine sufferers and controls. These findings indicate that both parasympathetic and sympathetic nerves supplying the eye are involved in migraine headache presumably due to effects on the pericarotid sympathetic fibers and involvement of trigeminal-parasympathetic reflexes.

椎动脉型颈椎病患者中缩血管活性肽类物质的变化及意义

目的　探索缩血管活性肽类物质在椎动脉型颈椎病发病时的变化情况及病理意义。方法　椎动脉型颈椎病治疗组 30例 ,正常组 30例 ,椎动脉型颈椎病患者均采用中医手法治疗。正常组和治疗组患者分别在治疗前和治疗后空腹取静脉血进行神经肽类物质NPY、ET、CGRP、ANP放射免疫检测。结果　治疗前椎动脉型颈椎病患者的血浆NPY、ET、ANP明显高于正常组 ,而CGRP的含量则低于正常组 (P <0 0 5) ;经过治疗后患者的血浆NPY、ET、ANP含量降低 ,CGRP的含量升高 ,与治疗前比较具有显著性差异 (P <0 0 5)。结论　缩血管活性肽类物质在椎动脉型颈椎病发病时可能起重要的神经 体液调节作用     

宫颈鳞癌中erbB3、erbB4基因蛋白表达与细胞凋亡和增殖的相关性研究

目的　探讨原癌基因erbB3、erbB4与细胞凋亡和增殖的关系 ,为该基因作用机制提供新线索。方法　分别采用免疫组化、DNA末端标记技术 (TUNEL法 )和HE染色检测 5 0例宫颈鳞癌中erbB3、erbB4基因蛋白表达及凋亡指数 (AI)和增殖指数 (MI)。结果　宫颈鳞癌中erbB3、erbB4表达率分别为 5 2 .5 %、44 .0 % ,AI、MI值分别为 5 .5 0± 4.10和 4.18± 3 .63 ,随着宫颈癌恶性程度增高、FIGO分期进展、肿瘤体积的增大和淋巴结转移组 ,erbB3、erbB4表达率增加 ,AI、MI值也增高 ,但差异仅在分化程度上有显著性 (P <0 .0 5 )。双变量相关分析显示erbB3、erbB4表达与AI、MI间无相关性 (r3=0 .10 98、0 .12 3 6,r4 =0 .2 15 1、0 .2 5 5 8,P >0 .0 5 )。结论　erbB3、erbB4和AI、MI预示着宫颈癌恶性潜能 ,但不能作为预后有用指标。erbB3、erbB4的作用机制可能不是通过细胞凋亡或增殖起作用     

不稳定型下颈椎损伤的手术治疗(附56例分析)

目的分析手术治疗下颈椎不稳定性损伤的适应证、手术方法及疗效。方法2001年1月～2003年1月,手术治疗下颈椎不稳定性损伤共56例。参照Aebi及White等人的手术适应证,以前路手术为主;对于难复性颈椎脱位或不伴椎间盘损伤者,行后路施术或前后联合入路手术;稳定性评分大于8分的前后柱损伤者,行前后联合入路手术。以Frankel评分系统评价神经功能恢复情况,以损伤节段Cobb角及水平移位来评价复位情况,采用Bohlman的X线片标准判定植骨融合情况。结果Frankel评分术前平均为2.3分,术后3.1分;按Bohlman标准3个月时植骨融合率为80%,6个月时为100%。术前Cobb角平均为8°,术后为1.5°,水平移位由术前的平均3.5mm减小到0.5mm。结论手术治疗下颈椎不稳定性损伤具有改善神经功能、恢复颈椎序列、恢复椎间高度及生理曲度、可早日下地活动等优点,手术病例及方法的选择应根据患者是否有致压因素及颈椎稳定性等综合考虑。

DNA flow cytometry in stage IB and II cervical carcinoma

In a retrospective study the prognostic significance of nuclear DNA content was investigated, as measured by flow cytometry, of the tumor specimens from 212 women with nonpretreated FIGO stage IB and II cervical cancer. One-hundred and thirty cases (62%) were found to be diploid, whereas 82 (38%) were aneuploid. Univariate analysis of the follow-up data showed an increased relative risk (RR) for recurrence free survival (RFS) for stage II tumors (RR = 1.87, 95% CI: 1.13–3.10, P = 0.015) and for age (RR = 1.52, 95% CI: 0.66–3.52 and RR = 2.35, 95% CI: 1.19–4.65, P = 0.032). Ploidy showed a relative risk of 1.33 (95% CI: 0.83–2.13, NS). In addition, univariate analysis of overall survival (OS) revealed similar results. For the subgroup of patients with primary surgery ( n = 151), positive pelvic nodes (RR = 5.38, 95% CI: 2.70–10.71, P = 0.0001) and parametrial extension (RR = 2.53, 95% CI: 1.24–5.17, P = 0.011) were significant factors for OS after univariate analysis, the estimated effects on RFS were slightly smaller. Multivariate analysis of RFS for the whole study population showed age, histologic grade and stage with a slightly increased risk, but no effect was significant. Ploidy with an RR of 0.97 (95% CI: 0.58–1.62) seems to have no influence on prognosis. For the subgroup with primary surgery, ploidy again failed statistical significance with an RR of 1.20 (95% CI: 0.58–2.49). Our results suggest that abnormalities of the nuclear DNA content in this homogeneous group of patients are associated with clinical and morphological prognosticators, however, ploidy is not an independent prognostic factor for RFS, or for the whole study population or for the subgroup with primary surgery.
