Randomized Controlled Trial
Management of Neuropathic Chronic Pain with Methadone Combined with Ketamine: A Randomized, Double Blind, Active-Controlled Clinical Trial.
Methadone and ketamine are used in neuropathic pain management. However, the benefits of both drugs association are uncertain in the treatment of neuropathic pain. ⋯ This study indicates that ketamine was better than methadone or methadone/ketamine for treating neuropathic pain.Key words: Multimodal analgesia, refractory pain, NMDA receptor, opioid.

Randomized Controlled Trial Comparative Study
Bipolar Versus Unipolar Intraarticular Pulsed Radiofrequency Thermocoagulation in Chronic Knee Pain Treatment: A Prospective Randomized Trial.
Chronic knee pain is a major widespread problem causing significant impairment of daily function. Pulsed radiofrequency has been shown to reduce severe chronic joint pain as a non-pharmacological and less invasive treatment method. ⋯ Bipolar IAPRF is more advantageous in reducing chronic knee pain and functional recovery compared with unipolar IAPRF. Further studies with longer follow-up times, laboratory-based tests, and different generator settings are required to establish the clinical importance and well-defined mechanism of action of PRF. This study protocol was registered at clinicaltrials.gov (identifier: NCT02141529), on May 15, 2014. Institutional Review Board (IRB) approval date: January 16, 2014, and number: 26/9Key words: Chronic pain, intraarticular, knee joint, knee osteoarthritis, pain management, pulsed radiofrequency treatment, quality of life, recovery of function.
