Disorders of the Autonomic Nervous System

1.4K
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Myasthenia Gravis: Diagnostic Tests

1.8K
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

318
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

科学领域:

  • 心脏病学 心脏病学
  • 神经学 神经学
  • 传染性疾病 传染性疾病

背景情况:

  • 长期COVID综合征,以COVID-19感染后的持续症状为特征,被怀疑涉及自主功能障碍.
  • 长期COVID中自主性障碍的确切性质和严重程度尚不清楚.

研究的目的:

  • 为了比较长期COVID患者的自主功能,健康的对照和已确定的纯自主衰竭的个体.
  • 为了阐明长期COVID患者自主功能障碍的程度.

主要方法:

  • 在三个组中进行了自主功能测试:长期COVID,COVID-19负控和纯自主功能衰竭患者.
  • 测量包括活跃站立时的心率和血压反应,瓦萨尔瓦机动,呼吸道鼻节律失常和倾斜桌面测试.

主要成果:

  • 与对照组相比,长期COVID患者在活动站立和倾斜桌面测试期间表现出更大的心率增加和血压下降.
  • 与对照组相比,长期COVID患者的Valsalva比率和呼吸道鼻失常值有所降低.
  • 经过年龄和性别调整后,长期COVID患者的自主功能障碍与纯自主性衰竭患者的功能障碍相似,感染后持续40个月.

结论:

  • 长期COVID患者表现出持续的自主功能障碍.
  • 这种功能障碍的严重程度类似于根据年龄和性别调整后,在纯自主性衰竭患者中观察到的情况.
