概括
后回性脑病综合征 (cvPRES) 的中心变异最常涉及大脑干,特别是小腿,并与高血压有关. 尽管症状严重,但cvPRES患者的治疗结果良好,死亡率低于典型的PRES.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 关键护理医学 关键护理医学
背景情况:
- 后回性脑病综合征 (PRES) 是一种神经疾病,其特征是血管性.
- 中央变体 (cvPRES) 是一种不典型的亚型,影响脑干和脊髓结构,对尾叶相对省略.
- 目前对于cvPRES没有统一的定义.
研究的目的:
- 系统地审查和元分析中央变异后倒置脑病综合征 (cvPRES) 的发生率,临床特征和结果.
- 为了比较cvPRES与典型的PRES在病因因素和患者结果方面.
主要方法:
- 系统审查和元分析遵循PRISMA指南,预先注册在PROSPERO.
- 质量评估使用乔安娜·布里格斯研究所和新城堡太华分别为案例报告和队列研究的尺度.
- 使用R-Studio与"metafor"包进行的元分析.
主要成果:
- 在PRES病例中cvPRES的聚合发病率为13% (95%CI:9-18%),观察到显著的异质性.
- 受影响个体的平均年龄为40.9岁,男性患病率为54%. 高血压是最常见的病因因素 (72%),其中50%的SBP>200 mmHg.
- 在88%的病例中,发现大脑干的干扰,特别是小腿 (70.45%),在88%的病例中被发现. 脊髓损伤 (PRES-SCI) 在18%的病例中发生. 死亡率很低,只有2%.
结论:
- cvPRES与血压升高密切相关,往往超过典型的PRES中所见的水平.
- 子是cvPRES中最常受到影响的中心结构.
- 尽管严重的高血压和脑干参与,cvPRES患者表现出良好的功能结果和较低的死亡率,可能是由于可逆性血管性胀而没有显著的神经元损伤.

Aneurysm II: Clinical Manifestations and Diagnostic Studies
24
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...

Seizures: Classification
596
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:
