概括

在感官神经病变中识别RFC1扩展至关重要. 慢性咳与特定的神经传导或超声检测结果相结合,强烈表明RFC1扩展,需要进行基因检测.

科学领域:

神经学神经学
遗传学是一个遗传学.
神经生理学神经生理学

背景情况:

双性致病性五核酸RFC1扩张与小脑缩症,神经病变和前置性缩症综合征 (CANAVS) 有关.
感官神经病变是一种早期指标,需要方法来识别患者进行遗传检测.

研究的目的:

确定临床和神经生理变量,以区分患有异常感官主导神经病变的患者,这些患者患有致病性RFC1扩张.
建立对表现为感官神经病变的患者进行遗传检测的标准.

主要方法:

对53名患有异常感官主导神经病变的患者进行了系统的临床再评估.
评估假设变量:慢性咳,,纯感官变化,非长度依赖的神经病变,超声波上的小神经大小,前庭和自主功能障碍.
在43名患有神经传导异常的患者中,对RFC1扩展进行基因测试.

主要成果:

在43名患者中,有5名患者的RFC1扩展检测结果呈阳性.
所有五个RFC1-阳性病例都报告了慢性咳 (P=0.0002).
四个RFC1阳性病例在超声波上显示了小的上肢神经截面面积 (<5.2mm2) (P=0.0006),四个有非长度依赖的感觉神经病变.

结论:

在超声波中,慢性咳与非长度依赖的神经病变或小神经大小相结合的存在显示了RFC1扩展的高灵敏度 (100%) 和特异性 (97%).
患有异常感官神经病变和这些特定的临床/神经生理特征的患者应接受RFC1扩展的基因检测.
神经传导研究和超声波是评估RFC1扩展患者的补充工具.

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...
