概括
与没有疼痛的个体和对照人群相比,疼痛性多神经病变显示出疼痛调制发生变化,空间总和增加,偏移止痛受损. 这些发现提高了对神经病痛疼痛机制的理解.
科学领域:
- 神经学 神经学
- 疼痛研究 疼痛研究
- 神经科学是一个神经科学.
背景情况:
- 多性神经病症带来了诊断挑战,对于疼痛和非疼痛形式的机制不明.
- 内源性疼痛调节,特别是时间和空间动态,在多神经病症中并未完全阐明.
研究的目的:
- 在远距离对称多神经病变中使用偏移止痛 (OA) 和疼痛空间总和 (SSp) 调查内源性疼痛调制.
- 为了比较这些疼痛调节措施之间的疼痛多神经病,无疼痛多神经病,和健康的对照组.
主要方法:
- 对90名参与者进行了定量感官测试 (30名疼痛性多神经病,30名无疼痛性多神经病,30名健康对照).
- 报销止痛 (OA) 和疼痛空间总和 (SSp) 用脚上的热刺激器进行了评估.
- 统计分析在三组中比较了OA和SSp.
主要成果:
- 与无疼痛和对照组相比,疼痛性多神经病患者的SSp显著增强 (P <0.05).
- 与健康对照组相比,患有疼痛性多神经病变的患者显示OA受损 (P <0.05).
- 无疼痛神经病症组表现出效率较低的OA和略微增强的SSp,尽管在统计学上并不显著.
结论:
- 患有疼痛性多神经病的人表现出内源性疼痛调节的明显障碍,其特点是增强空间总和和减少偏移止痛.
- 研究结果表明,空间总和变化是由较小的受体场驱动的,这有助于理解多神经病痛的病理生理学.
- 空间和时间疼痛调节动态的不同作用为改善多神经病的诊断和预后提供了潜力.

Nociception
33.1K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.4K
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...

Pain
1.2K
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Analgesia and Pain Management
1.5K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
