Primary trigeminal neuralgia (TN) is a common clinical refractory neuralgia. Severe pain is experienced during episodes, severely impacting the patient's quality of life. Long-term suffering from the disease can lead to anxiety, depression, and even suicide. The pathological processes involved in TN are complex, the mechanisms of pathogenesis are unknown, and effective treatment is lacking. ⋯ Complication, continuous radiofrequency thermocoagulation, pulsed radiofrequency, recurrence rate, trigeminal neuralgia, Visual Analog Scale.

The growth of interventional pain medicine in recent years has resulted in more procedures being carried out under fluoroscopic guidance. The proximity of the pain physician (PP) to ionization radiation (IR) potentially increases the risk of radiation exposure to the ocular region. A European directive has reduced the limits of occupational ocular dose 7.5-fold. ⋯ Ionizing radiation, ocular, radiation protection, pain medicine, interventional.

Electroacupuncture (EA) has been proved to be effective in treating certain neuropathic pain conditions. The mechanisms of pain relief by EA are not fully understood. There have been sporadic reports of damage in the peripheral nervous system (PNS) and regions of the central nervous system (CNS) at the ultrastructural level following peripheral nerve injury. However, information about possible systemic changes in the PNS and CNS after nerve injury is scarce. ⋯ Sciatic neuralgia, cobra venom, demyelination, electroacupuncture, pregabalin, rat model.

Comparative Study
Comparison of 3 Anesthetic Methods for Percutaneous Transforaminal Endoscopic Discectomy: A Prospective Study.
Percutaneous transforaminal endoscopic discectomy (PTED) under local anesthesia (LA) is growing popular in recent years because of its safety, effectiveness and increased patient demands for minimally invasive procedures. To avoid neural injuries, local anesthesia that can keep the patient conscious is recommended. However, many patients complain about the severe pain during surgery. Epidural anesthesia (EA) is an alternative choice. We put forward an anesthetic method that combined preemptive analgesia (PA) and local anesthesia. ⋯ Percutaneous transforaminal endoscopic discectomy (PTED), local anesthesia, epidural anesthesia, preemptive analgesia, morphine, ropivacaine, pain management, visual analog scale (VAS), Oswestry Back Pain Disability Index (ODI).
