The analgesic mechanism of long-lasting exercise on neuropathic pain is not well understood. This study explored the effects of swimming training on neuropathic pain and the expression of irisin, GAD65, and P2X3 after chronic constriction injury (CCI) of the sciatic nerve. ⋯ Our findings showed that four weeks of swimming training produce beneficial rehabilitative effects on neuropathic pain symptoms. The analgesic effect of swimming training is partially related to the increase of GAD65. The beneficial role of irisin in neuropathic pain will require further investigation.

Electrical stimulation of the spinal cord is commonly used to treat neuropathic pain. However, epidural space adhesion caused by previous surgery may interfere with precise electrical lead placement. We here report a case of successful placement of electrical leads via an extraforaminal approach in the management of recurrent pain after primary spinal cord stimulation. Extraforaminal nerve root stimulation may be an alternative choice for repeated epidural spinal cord stimulation in cases of recurrent neuropathic pain.

Observational StudyRobot-Guided Neuronavigated Repetitive Transcranial Magnetic Stimulation (rTMS) in Central Neuropathic Pain.
To confirm and extend previous results involving repetitive transcranial magnetic stimulation (rTMS) aimed at alleviating refractory central neuropathic pain (CNP). To evaluate pain relief in detail and to assess ongoing benefits after one year of treatment. ⋯ These results confirm that multiple rTMS sessions are both safe and have potential as a treatment for CNP. An ongoing randomized controlled trial will allow teasing out of this effect from placebo analgesia.

Tobacco smoking is particularly evident in individuals experiencing chronic pain. This complex relationship is poorly understood at both molecular and behavioral levels. Here, we describe experiments aimed at understanding whether a chronic pain state induces neuroadaptations into the brain or peripheral nerves that involve nicotinic acetylcholine receptors (nAChRs) and whether these neuroadaptations directly lead to increased vulnerability to nicotine addiction or to the development of coping strategies to relieve pain symptoms. ⋯ Spinal nerve ligation and sham rats were equally sensitive to nicotine-induced anxiety-like behavior and antinociception; however, nicotine produced a potent and long-lasting antiallodynic effect in spinal nerve ligation rats. These results demonstrate that chronic pain leads to plasticity of nAChRs that do not directly facilitate nicotine addictive behaviors. Instead, nicotine potently decreases allodynia, an effect that could lead to increased nicotine consumption in chronic pain subjects.

To evaluate the association between dry eye (DE) symptoms and neuropathic-like ocular pain (NOP) features, chronic pain conditions, depression, and anxiety in patients presenting for routine ophthalmic examinations. ⋯ Dry eye severity positively associated with NOP complaints, comorbid chronic pain conditions, and symptoms of depression and anxiety.
