概括

与对照组相比,外围神经超声波显示,肌缩侧硬化症 (ALS) 患者的横截面区域 (CSA) 减少. 靠近中枢神经CSA可能作为ALS中神经运动纤维损失的潜在生物标志物.

科学领域:

神经学神经学
神经生理学神经生理学
医疗成像医学成像

背景情况:

周围神经超声波对于诊断神经肌肉疾病越来越重要.
使用超声波从多焦点运动神经病变 (MMN) 区分肌缩性侧面硬化症 (ALS) 是一个活跃的研究领域.
与健康个体相比,ALS对外围神经截面区域 (CSA) 的影响仍然是一个关键问题.

研究的目的:

调查和量化被诊断患有肌缩侧面硬化症 (ALS) 的患者外周神经的横截面积 (CSA).
将ALS患者的外围神经CSA与健康对照群进行比较.
探索外围神经超声波在检测ALS神经损伤中的潜力.

主要方法:

该研究招募了139名ALS患者和75名健康对照.
在所有参与者的中枢神经,神经,臂干和部神经根部进行了超声检查.
在ALS和对照组之间分析和比较这些外周神经的横截面 (CSA).

主要成果:

与对照人群相比,ALS患者表现出中枢神经的CSA,神经的大部分部分,臂干和部神经根的轻微减少.
一个值得注意的发现是,在ALS患者中,中枢神经的CSA相比椎神经的CSA减少更为明显,特别是在近端段中.
这些结果表明,超声波可以检测ALS特征的神经运动纤维损失.

结论:

周围神经超声波在患有骨髓缩侧面硬化症 (ALS) 的个体中显示了对神经运动纤维损失的敏感性.
靠近中枢神经的横截面 (CSA) 是一个有前途的生物标志物,可用于识别ALS患者的神经损伤.
超声波的发现有助于了解ALS病理生理学的外周神经参与.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

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...

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
