概括
偏头痛患者表现出疼痛调节受损,特别是那些没有药物过度使用头痛而患有慢性偏头痛的人. 疼痛处理在偏头痛各个阶段各不相同,这表明疼痛调节的周期性变化可能会影响偏头痛复发.
科学领域:
- 神经科学是一个神经科学.
- 疼痛研究 疼痛研究
- 神经学 神经学
背景情况:
- 抵消疼痛,减少热刺激感知疼痛的减少,表明内源性疼痛调节.
- 这项研究研究了在偶发性和慢性偏头痛患者中通过偏移性止痛来处理疼痛.
研究的目的:
- 检查间歇性发作性偏头痛中的偏移止痛与非间歇性慢性偏头痛的对比.
- 在情节性偏头痛中,探索整个偏头痛周期的疼痛调制变化.
- 比较慢性偏头痛患者有和没有药物过度使用头痛 (MOH).
主要方法:
- 纳入了68名情节性偏头痛患者 (跨偏头痛阶段),34名慢性偏头痛患者 (有/没有MOH),以及30名对照患者.
- 参与者接受了额头上的热刺激偏移测试.
- 用视觉模拟尺度 (VAS) 测量疼痛反应.
主要成果:
- 抵消性止痛作用存在于后节期性情节性偏头痛和对照人群中,但不在间节期性情节性偏头痛和MOH的慢性偏头痛中.
- 在 preictal/ictal 间歇性偏头痛和没有 MOH 的慢性偏头痛中发生了疼痛缓解.

01:25Analgesia and Pain Management
420
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...

203
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

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.

Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

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...
