Patients with chronic neuropathic pain (NP) have a significantly increased risk of central nervous degeneration. Trigeminal neuralgia (TN) is a typical NP, and this manifestation is more obvious. In addition to severe pain, patients with TN are often accompanied by cognitive dysfunction and have a higher risk of central nervous system degeneration, but the mechanism is not clear. ⋯ Interestingly, NLRP3 specific blocker MCC950 can alleviate the neurodegeneration of trigeminal neuralgia rats to a certain extent. It is suggested that our NLRP3 inflammasome plays an important role in the neurodegeneration of trigeminal neuralgia rats. And it is related to the activation of central nervous system inflammation.

Neuropathic pain (NP) and complex regional pain syndrome (CRPS) in children can result in significant disability and emotional distress. Early assessment and treatment could potentially improve pain, function, quality of life, and reduce costs to the health care system. Currently, there are no screening tools for pediatric NP and CRPS. This research aimed to develop and establish the content validity of a screening tool for pediatric NP and CRPS using a phased approach. ⋯ The Pediatric PainSCAN is a novel screening tool that has undergone rigorous development and content validity testing. Further research is needed to conduct item reduction, determine scoring, and test additional measurement properties.

To investigate the efficacy of repeated application of capsaicin 179 mg cutaneous patch in nonresponders to the first application. ⋯ Although some patients with peripheral neuropathic pain experience rapid improvements with a single treatment of capsaicin 179 mg patch, some may require two or three treatments before an initial response is observed. Similar benefits for pain, sleep, and QOL can be achieved in early and late responders.
