Evaluation of a Pharmacist Managed Telephone Pain Clinic for Neuropathy Treatment.
Pain is prevalent in our society, affecting more than a quarter-million U. S. adults and leading to poor patient outcomes. At the Veteran's Affairs San Diego Healthcare System (VASDHS), a Telephone Pain Clinic (TPC) was developed to improve these outcomes. ⋯ At discharge, pain medications that were increased were use of serotonin and norepinephrine reuptake inhibitors (SNRIs), pregabalin, and capsaicin. Management by the TPC showed promise and trends toward reducing pain experienced by patients with diabetic neuropathy, fibromyalgia, or postherpetic neuralgia. The TPC also may be more effective in maximizing evidenced-based pharmacotherapy for neuropathic pain, suggesting expertise by pharmacist clinical specialists.

Puerarin alleviates vincristine-induced neuropathic pain and neuroinflammation via inhibition of nuclear factor-κB and activation of the TGF-β/Smad pathway in rats.
Chemotherapy-induced neuropathic pain harms the quality of life patients. Vincristine is an often used chemotherapeutic drug that evokes neuralgia via inflammation. Puerarin (Pue) extracted from Puerariae Lobatae Radix has analgesic and anti-inflammatory effects; however, its possible effect and mechanism in vincristine (Vin)-induced neuropathic pain has not been investigated. ⋯ Immunofluorescence staining further demonstrated that Pue decreased the NF-κBp65 protein. Our findings imply that Pue relieved chemotherapy-induced neuropathic pain might be attributable to the suppression of inflammation cytokines. The anti-inflammation action of Pue might be associated with the activation of the TGF-β/Smad pathway, a novel mechanism exploring its prophylactic effect in vincristine-induced neuropathic pain.

Evaluation of circulating microRNA expression in patients with trigeminal neuralgia: An observational study.
Trigeminal neuralgia (TN) is a chronic neuropathic pain that seriously affects the daily life of patients. There is increasing evidence that microRNAs (miRNAs) play an important role in the development of neuropathic pain. In this study, the TaqMan Low Density Array (TLDA) was used to analyze the serum miRNA levels of 28 TN patients, and 31 healthy people without any neuropathic pain were used as controls. ⋯ The analysis further confirmed that the expression levels of 4 miRNAs, including miR-132-3p, miR-146b-5p, miR-155-5p, and miR-384, were significantly higher than those of healthy controls, and the difference was statistically significant. This study preliminarily confirmed the changes of serum miRNA expression profile in TN patients. Among them, 4 kinds of serum miRNA are likely to be related to the occurrence and development of TN.

Cannabis has a long history of medical use. Although there are many cannabinoids present in cannabis, Δ9tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD) are the two components found in the highest concentrations. CBD itself does not produce typical behavioral cannabimimetic effects and was thought not to be responsible for psychotropic effects of cannabis. ⋯ The dose and route of the administration-dependent effect of CBD, on the reduction in pain, hyperalgesia or allodynia, as well as the production of pro and anti-inflammatory cytokines, were described depending on the disease model. The clinical applications of CBD-containing drugs are also mentioned. The data presented herein unravel what is known about CBD's pharmacodynamics and analgesic effects to provide the reader with current state-of-art knowledge regarding CBD's action and future perspectives for research.
