概括
超声波 (美国) 可以通过测量神经大小和血液流动来区分肌缩性侧面硬化症 (ALS),慢性炎症性脱髓化多基基隆性神经病 (CIDP) 和夏科特-玛丽-牙病 (CMT). 在ALS中较大的神经大小可能表明炎症和受损的血神经屏障.
科学领域:
- 神经学 神经学
- 医疗成像医学成像
- 周围神经疾病 周围神经疾病
背景情况:
- 超声波 (美国) 是一种非侵入性成像技术,用于检测周围神经的变化.
- 区分肌缩性侧面硬化 (ALS),慢性炎症性脱髓化多基原蛋白神经病 (CIDP) 和夏科特-玛丽-图斯病 (CMT) 可能是一个挑战.
研究的目的:
- 评估高分辨率神经超声波在区分ALS,CIDP和CMT的有用性.
- 为了在这些条件下比较神经横截面积 (CSA) 和微血管血流.
主要方法:
- 在患有ALS (n=11),CIDP (n=5),CMT (n=5) 和对照组 (n=15) 的患者身上进行了神经的高分辨率超声波.
- 神经CSA和血流被分析并与临床数据,脑脊液 (CSF) 测量和神经传导研究相关联.
- 这项研究是比较美国与7特斯拉磁共振神经图 (7T MRN) 的大型多式联络调查的一部分.
主要成果:
- 与ALS和对照组相比,神经CSA在CMT和CIDP中显著更大.
- 神经微血管血流在CIDP中最高,其次是CMT,ALS和对照.
- 在ALS中,增加的CSA与增加的CSF总蛋白和白蛋白系数相关,这表明潜在的血神经屏障破坏.
结论:
- 神经超声波参数,包括CSA和血流,显示在ALS,CIDP和CMT之间进行区分的可行性,即使样本大小小小.
- 在ALS中,较大的神经CSA可能意味着具有受损血神经屏障完整性的炎症亚型.
- 未来的研究将探索US和7TMRN的综合价值,以区分炎症和退行性疾病变体.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
17
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
870
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...
