概括
腹病毒 (Varicella zoster virus,VZV) 的重新激活会导致严重的中枢神经系统问题. 这项研究强调了疹急性边缘脑炎 (HZ ALE),这是一个罕见但显著的并发症.
科学领域:
- 神经学 神经学
- 传染性疾病 传染性疾病
- 病毒学 病毒学
背景情况:
- 疹病毒 (Varicella zoster virus,VZV) 在初级感染 (水) 后的头骨和脊髓质中建立潜伏期.
- 由于衰老,免疫抑制或压力,可以发生被称为疹病毒 (HZ) 的VZV重新激活,导致各种并发症.
研究的目的:
- 描述与HZ相关的中枢神经系统 (CNS) 并发症的临床特征,诊断发现和假定的侵入性途径.
- 具体报告一系列患有HZ相关急性边缘性脑炎 (HZ ALE) 的患者,这是一个罕见的表现.
主要方法:
- 追溯15名中枢神经系统HZ并发症患者的病例系列.
- 分析了临床数据,神经成像 (MRI) 和脑脊液 (CSF) VZV聚合酶链反应 (PCR) 结果.
- 专注于5名被诊断患有HZ ALE的患者.
主要成果:
- 常见的中枢神经系统HZ并发症包括急性脑炎,血管炎,脑膜炎和神经.
- 急性边缘脑炎 (ALE) 是一个值得注意的并发症 (n=5),在MRI上经常出现发烧,意识变化和中间叶病变.
- 在五名患者中,CSF VZV PCR呈阳性;HZ ALE皮疹主要分布在三角神经分布中.
结论:
- HZ ALE 是VZV再激活的一个未被报告的并发症,其特点是特定的临床和放射学发现.
- 中枢神经系统入侵的可变途径,包括脑干,血管病,脑膜扩散和病毒病,都与中枢神经系统的HZ并发症有关.
- 全球HZ发病率的增加需要对HZ ALE进行临床意识,特别是在出现发烧,皮疹和意识改变的患者中.

Antiepileptic Drugs: Glutamate Antagonists
267
Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...
