概括
抗N-甲基-D-酸盐受体 (NMDAR) 脑炎的复发不常见,并且不那么严重. 早期免疫疗法,特别是rituximab,以及第一个发作期间的CSF多细胞化,可能会降低复发风险.
科学领域:
- 神经学 神经学
- 免疫学 免疫学 免疫学
- 神经免疫学 神经免疫学
背景情况:
- 复发发生在高达25%的抗N-甲基-D-酸盐受体 (NMDAR) 脑炎患者中.
- 描述复发和识别预测因素对于管理至关重要.
研究的目的:
- 为了临床描述抗NMDAR脑炎复发的临床特征.
- 为了确定第一个发作期间复发的预测因素.
- 评估免疫治疗对复发发生的影响.
主要方法:

Seizures: Classification
612
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Aneurysm II: Clinical Manifestations and Diagnostic Studies
27
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Myocarditis II: Clinical Features and Diagnostic Tests
32
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
