小儿病毒性脑炎继发癫痫的EEG影像学及临床分析

目的探讨儿童病毒性脑炎继发癫痫(PEE)的脑电图(EEG)及影像学特点,进一步探讨其临床高危因素。方法以明确诊断的34例PEE患儿为观察组,选取同时期就诊的同年龄段病毒性脑炎未继发癫痫(no-PEE)患儿102例为对照组。收集患儿病毒性脑炎(VE)急性期临床资料,并进行随访。结果单因素分析得出2组病脑急性期痫性发作≥2次、癫痫持续状态(SE)、昏迷,EEG癫痫样放电、广泛或弥漫性慢波,影像学单纯皮层受损、皮层及皮层下受损、丘脑基底节受损差异有统计学意义(P<0.05)。多因素Logistic回归分析显示,病毒性脑炎急性期痫性发作≥2次、SE、昏迷、EEG癫痫样放电、影像学皮层及皮层下同时受损差异有统计学意义(P<0.05),为PEE危险因素。2组患儿随访期间智力发育落后差异有统计学意义(P<0.001)。结论病毒性脑炎急性期EEG癫痫样放电、影像学皮层及皮层下同时受损、痫性发作≥2次、SE、昏迷为PEE危险因素。PEE患儿远期多有智力发育落后,应密切随访,及时干预治疗。     

儿童中枢神经系统感染治疗疗程与腰椎穿刺检查系列建议之一——病毒性脑（膜）炎治疗疗程与腰椎穿刺检查建议

中枢神经系统感染是儿童神经系统常见疾病,也是临床住院的常见病种;中枢神经系统感染的病原以细菌和病毒感染较为常见,而结核菌、真菌、支原体感染相对少见;不同病原的中枢神经系统感染临床上有其共性表现又有不同病原感染疾病的特点;中枢神经系统感染的诊断包括病原学确诊或临床疑诊;不同的治疗转归其治疗疗程或腰穿检查与复查时间均缺乏研究性证据,困扰临床一线工作。为此,中华医学会儿科学分会神经学组组织的专家组制订了“儿童中枢神经系统感染治疗疗程与腰椎穿刺检查系列建议”,希望能为这一疾病的诊治提供参考。     

Intravenous methylprednisolone versus therapeutic plasma exchange for treatment of anti‐n‐methyl‐d‐aspartate receptor antibody encephalitis: A retrospective review

Introduction : Anti‐N‐methyl‐d ‐aspartate (NMDA) receptor antibody encephalitis is an increasingly recognized form of autoimmune encephalitis. Conventional treatments include therapies such as corticosteroids, intravenous immunoglobulin (IVIg), and/or therapeutic plasma exchange (TPE). Although TPE is regularly used for treatment of anti‐NMDA receptor antibody encephalitis, the American Society for Apheresis has given it a category III recommendation only. Earlier administered immunotherapies in tumor‐negative patients may facilitate faster recoveries, but it remains unclear whether or not TPE is superior to steroids and/or IVIG. Methods : We retrospectively evaluated 10 of 14 patients that received steroids and TPE with modified Rankin scores and subjectively assessed the point of largest sustained improvement in all 14 patients. Results : In the patients that received both steroids and TPE at our institution during the same hospitalization (only 10 of 14 patients), 7/10 patients after TPE had improved with the modified Rankin score versus 3/10 patients after steroids. The average modified Rankin score improvement after steroids in this group was ?0.1 as compared with 0.4 after TPE. Based on subjective chart review analysis during which all 14 patients were assessed, the largest sustained improvement occurred immediately following the third–fifth exchange in 9/14 patients, whereas only 2/14 patients appeared to have had significant benefit immediately following steroids. Conclusions : This is compelling preliminary data that suggests that corticosteroids may not be as effective compared to steroids followed by TPE. Given the importance of time‐sensitive treatment, more formal studies may illuminate the ideal first‐line treatment for anti‐NMDA receptor antibody encephalitis. J. Clin.
