Due to pathophysiology of the disease certain anaesthesiological complications associated with HMSN can be related. A case report describing protocol of the total venous anesthesia in the 17-year old patient operated on sacral dermoid with fistulae is presented. The patient recovered without any further complications. In the conclusion we would like to bring the importance of awareness to prepare the HMSN patient for a surgical procedure as well from anesthesiological as from surgical point of view to avoid possible unwanted event such as malignant hyperthermia, hyperkalemia, seizures, prolonged effect of muscle relaxants and worsening of the disease. As an important alternative to general anesthesia regional anesthesia should be considered.展开更多

In the present study, we recruited 500 diabetic patients from the Fourth Affiliated Hospital of Kunming Medical University in China from June 2008 to September 2013：221 cases showed symptoms of peripheral neuropathy （symptomatic group） and 279 cases had no symptoms of peripheral impairment （asymptomatic group）. One hundred healthy control subjects were also recruited. Nerve conduction studies revealed that distal motor latency was longer, sensory nerve conduction velocity was slower, and sensory nerve action potential and amplitude of compound muscle action potential were significantly lower in the median, ulnar, posterior tibial and common peroneal nerve in the diabetic groups compared with control subjects. Moreover, the alterations were more obvious in patients with symptoms of peripheral neuropathy. Of the 500 diabetic patients, neural conduction abnormalities were detected in 358 cases （71.6%）, among which impairment of the common peroneal nerve was most prominent. Sensory nerve abnormality was more obvious than motor nerve abnormality in the diabetic groups. The amplitude of sensory nerve action potential was the most sensitive measure of peripheral neuropathy. Our results reveal that varying degrees of nerve conduction changes are present in the early, asymptomatic stage of diabetic peripheral neuropathy.展开更多

文摘目的:分析中国汉族人群遗传性周围神经病(hereditary peripheral neuropathy,HPN)致病基因的分布特点,探讨HPN与相关疾病的潜在发病机制和治疗前景。方法:收集2007年1月到2022年5月在北京大学第三医院和中日友好医院诊治的HPN先证者666个,用多重连接探针扩增技术确定PMP22重复和缺失突变后,用二代测序基因包或全外显子组测序,Sanger法进行一代验证,分析比较结果。结果:腓骨肌萎缩症(Charcot-Marie-Tooth,CMT)在HPN中所占比例最高,为74.3%(495/666),其中69.1%(342/495)的患者获得基因确诊。最常见的基因突变为PMP22重复、MFN2和GJB1突变,占CMT总体确诊患者的71.3%(244/342)。遗传性运动神经病(hereditary motor neuropathy,HMN)所占比例为16.1%(107/666),43%(46/107)为基因确诊,最常见的基因突变为HSPB1、t-RNA合成酶相关基因(aminoacyl-tRNA synthetases)和SORD突变,占HMN总体确诊患者的50%(23/46)。HMN的部分基因可以合并多种临床表型,如HSPB1、GARS、IGHMBP2可同时引起HMN和CMT,HMN叠加综合征的患者与肌萎缩侧索硬化(KIF5A、FIG4、DCTN1、SETX、VRK1)、遗传性痉挛性截瘫(KIF5A、ZFYVE26、BSCL2)和脊肌萎缩症(MORC2、IGHMBP2、DNAJB2)有共同的致病基因。遗传性感觉自主神经病(hereditary sensory and autosomal neuropathy,HSAN)在HPN中所占的比例较小,为2.6%(17/666),最常见的致病基因为SPTLC1突变。引起遗传性淀粉样周围神经病的基因主要是TTR,本研究中最常见的基因突变位点是p.A117S和p.V50M,表现为晚发和比较突出的自主神经受累。结论:CMT和HMN是最常见的HPN,HMN与CMT2的致病基因有很多交叉,部分HMN致病基因与肌萎缩侧索硬化、遗传性痉挛性截瘫和脊肌萎缩症有重叠,提示不同疾病之间可能存在潜在的共同致病通路。
