概括
儿童血压升高可能是早期N- 甲基- d- 酸盐受体脑炎 (pNMDARE) 的信号. 这种重要标志可以帮助医生更快地怀疑病情,
科学领域:
- 儿童神经学
- 免疫学
- 临床诊断
背景情况:
- 儿童N- 甲基- d- 酸盐受体 (pNMDARE) 脑炎出现严重的神经心理症状.
- 由于症状与其他疾病重叠,早期诊断具有挑战性,通常会延迟关键的腰椎穿刺 (LP) 程序.
- 自主功能障碍是PNMDARE的一个已知的特征.
研究的目的:
- 调查早期生命体征,特别是血压是否可以作为升级PNMDARE评估的非侵入性生物标志物.
- 确定pNMDARE的潜在早期临床标志物,以帮助及时诊断.
主要方法:
- 对pNMDARE患者和没有pNMDARE患者的回顾性病例对照分析 (2021-2023年).
- 确认的pNMDARE病例与对照病例之间的生命体征,特别是血压百分值的比较.
- 统计分析包括接收器操作曲线 (ROC) 分析,以确定血压百分位数的诊断准确性.
主要成果:
- 与对照组相比,pNMDARE患者的标准化静脉压和静脉压百分位数显著提高.
- 对于pNMDARE,ROC分析确定了特定的血压百分值值,具有显著的敏感性和特异性.
- 静脉血压升高 (第99位) 和静脉血压升高 (第88. 5位) 显示可能导致pNMDARE的分化.
结论:
- 血压升高被认为是pNMDARE的早期临床标志物.
- 这一发现支持了pNMDARE中dysautonomia的理解.
- 需要进一步的研究和验证,以将高血压纳入pNMDARE的临床查工具.

Viral Meningitis
156
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
