Reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistological analysis of spinal cord and pain behavior analysis in a rat neuropathic pain model were conducted to examine the function of microglial basic fibroblast growth factor (bFGF) in the development of neuropathic pain. ⋯ N/A.

Randomized Controlled Trial Multicenter Study Comparative Study
Capsaicin 8% patch versus oral pregabalin in patients with peripheral neuropathic pain.
Clinical trials have not yet compared the efficacy of capsaicin 8% patch with current standard therapy in peripheral neuropathic pain (PNP). ⋯ The capsaicin 8% patch provided non-inferior pain relief to an optimized dose of pregabalin in PNP, with a faster onset of action, fewer systemic side effects and greater treatment satisfaction.

The research of new therapeutic strategies for neuropathic pain represents a major current priority. Important drawbacks to advance in the development of these therapies are the limited translational value of the animal models now available and the elucidation of the complex neuronal and immune pathophysiological mechanisms underlying neuropathic pain. One of the neurotransmitter systems participating in neuropathic pain control that has recently raised a particular interest is the endocannabinoid system. ⋯ Several clinical studies suggest that cannabinoids significantly reduced neuropathic pain, although most of these trials fail the required standards of quality. The different pain patient populations included in the systematic reviews also make it difficult to get adequate conclusions. Therefore, additional clinical trials that consider an adequate number of patients, the use active treatments as controls, and longer duration of administration are required to have an adequate profile of the effectiveness and safety of cannabinoids in neuropathic pain.
