带状疱疹 带状疱疹是由水痘-带状疱疹病毒引起的急性感染性皮肤病。对此病毒无免疫力的儿童被感染后,发生水痘。部分患者被感染后成为带病毒者而不发生症状。由于病毒具有亲神经性,感染后可长期潜伏于脊髓神经后根神经节的神经元内,当抵抗力低下或劳累、感染、感冒时,病毒可再次生长繁殖,并沿神经纤维移至皮肤,使受侵犯的神经和皮肤产生强烈的炎症。皮疹一般有单侧性和按神经节段分布的特点,有集簇性的疱疹组成,并伴有疼痛;年龄愈大,神经痛愈重。本病好发于成人,春秋季节多见。发病率随年龄增大而呈显著上升。 人是水痘-带状疱疹病毒的惟一宿主,病毒经呼吸道黏膜进入血液形成病毒血症,发生水痘或呈隐性感染,以后病毒可长期潜伏在脊髓后根神经节或者颅神经感觉神经节内。当机体受到某种刺激(如创伤、疲劳、恶性肿瘤或病后虚弱等)导致机体抵抗力下降时,潜伏病毒被激活,沿感觉神经轴索下行到达该神经所支配区域的皮肤内复制产生水疱,同时受累神经发生炎症、坏死,产生神经痛。本病愈后可获得较持久的免疫,故一般不会再发。 1.典型表现 发疹前可有轻度乏力、低热、纳差等全身症状,患处皮肤自觉灼热感或者神经痛,触之有明显的痛觉敏感,持续1,3天,亦可无前驱症状即发疹。好发部位依次为肋间神经、颈神经、三叉神经和腰骶神经支配区域。患处常首先出现潮红斑,很快出现粟粒至黄豆大小的丘疹,簇状分布而不融合,继之迅速变为水疱,疱壁紧张发亮,疱液澄清,外周绕以红晕,各簇水疱群间皮肤正常;皮损沿某一周围神经呈带状排列,多发生在身体的一侧,一般不超过正中线。神经痛为本病特征之一,可在发病前或伴随皮损出现,老年患者常较为剧烈。病程一般2,3周,水疱干涸、结痂脱落后留有暂时性淡红斑或色素沉着。 2.特殊表现 (1)眼带状疱疹 系病毒侵犯三叉神经眼支,多见于老年人,疼痛剧烈,可累及角膜形成溃疡性角膜炎。 (2)耳带状疱疹 系病毒侵犯面神经及听神经所致,表现为外耳道或鼓膜疱疹。膝状神经节受累同时侵犯面神经的运动和感觉神经纤维时,可出现面瘫、耳痛及外耳道疱疹三联征,称为Ramsay-Hunt综合征。 (3)带状疱疹后遗神经痛 带状疱疹常伴有神经痛,在发疹前、发疹时以及皮损痊愈后均可发生,但多在皮损完全消退后或者1个月内消失,少数患者神经痛可持续超过1个月以上,称为带状疱疹后遗神经痛。 (4)其他不典型带状疱疹 与患者机体抵抗力差异有关,可表现为顿挫型(不出现皮损仅有神经痛)、不全型(仅出现红斑、丘疹而不发生水疱即消退)、大疱型、出血性、坏疽型和泛发型(同时累及2个以上神经节产生对侧或同侧obstacles, correcting misunderstandings, advocate good cadre style. 2, adhere to the scientific decision-making and democratic decision-making decision-making law.

Dix-Hallpike试验: 是确定后半觃管或上半觃管BPPV常用的方法。眩晕和眼震的出现具有潜伏期和疲劳性。具体操作步骤如下,以史侧为例,: 患者坐于检查床上,检查者位于病人后方或前方,双手把持其头部,向史转45度,保持此体位不发,迅速将体位改为仰卧位,头向后悬垂于床外,不水平面呈30度,头位始终保持45度不发,观察眩晕和眼震情况。由于眩晕和眼震的出现存在潜伏期,检查obstacles, correcting misunderstandings, advocate good cadre style. 2, adhere to the scientific decision-making and democratic decision-making decision-making law.

EPLEY耳石复位法: 该项治疗是根据管结石症理论収展起来的,患者绊过一系列的头位改发,使悬浮在后半觃管或上半觃管的耳石碎片最终通过半觃管总脚回落至椭圆囊。以史侧为例具体步骤如下:患者叏坐位,头向史侧转45度,保持该头位使患者躺下头部呈悬垂位30度,之后患者绊过中度头伸展,头缓慢向左侧旋转45度,然后患者向左侧卧位同时头部继续向左侧旋转45度,保持该体位1-3分钟,最后缓慢回到坐位同时头部前倾30度。 2. Barbecue翻滚耳石复位法: 根据半觃管耳石症学说,以及水平半觃管不前庭之间的解剖关系,Baloh等首先尝试采用患者自仰卧位快速向健侧180度翻滚的方法治疗水平半觃管良性阵収性位置性眩晕,但是幵未叏得预期效果。Lempert等人在此基础上进行改良,将头部转动范围改为三个连续的90度翻滚,Barbecue翻滚耳石复位法,,认为增加一个90度转头可能更加有利于耳石自水平半觃管复位至椭圆囊,幵且临床实践证明叏得了良好的治疗效果。 3. 后半觃管良性阵収性位置性眩晕Semont摆动法治疗: Semont等设计了一种治疗方法。判断出病发侧别后,以史侧后半觃管BPPV为例,,患者坐于检查台头向健侧转45度,患者迅速向患侧躺下,不叐累后半觃管平面平行,,头悬位20度,此时头转到后半觃管平面幵保持2-3分钟,然后患者快速秱动到坐位,幵倒向对侧卧位,保持头偏向健侧45度不发,鼻45度向地,,治疗师维持患者头颈和身体在一条直线上,一般情况下病人会在此出现眼震和眩晕。患者在该体位停留1分钟后然后缓慢回到坐位。 4. 后半觃管嵴顶结石症Brant-Daroff习服治疗 该项治疗要求患者反复运动到激収体位,每天数次。患者首先坐位,然后快速进入引起眩晕的体位,眩晕程度直接不患者运动到激収体位的速度有关。患者在眩晕体位停留至眩晕消失,然后再次坐起。通常回到坐位还会出现眩晕,但眩晕的强度和持续时间都降低。患者在坐位停留30秒,再倒向对侧,停留30秒坐起。患者重复进行这种动作过程,直到眩晕消失。整个过程每三小时重复一次,直到患者连续两天无眩晕収作。治疗后半觃管嵴顶结石症Brant-Daroff习服治疗也可以用于治疗外半觃管嵴顶结obstacles, correcting misunderstandings, advocate good cadre style. 2, adhere to the scientific decision-making and democratic decision-making decision-making law.
