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.

Nerve Injury Decreases Hyperacute Resting-State Connectivity Between the Anterior Cingulate and Primary Somatosensory Cortex in Anesthetized Rats.
A better understanding of neural pain processing and of the development of pain over time, is critical to identify objective measures of pain and to evaluate the effect of pain alleviation therapies. One issue is, that the brain areas known to be related to pain processing are not exclusively responding to painful stimuli, and the neuronal activity is also influenced by other brain areas. Functional connectivity reflects synchrony or covariation of activation between groups of neurons. ⋯ The interaction was quantified as the calculated correlation and coherence. The results from the intervention group showed a decrease in correlation between ACC and SI activity, which was most pronounced in the hyperacute phase but a longer time frame may be required for plastic changes to occur. This indicated that both SI and ACC are involved in hyperacute pain processing.

Paeoniflorin attenuates chronic constriction injury-induced neuropathic pain by suppressing spinal NLRP3 inflammasome activation.
Neuropathic pain remains one of the most common pain conditions worldwide. Accumulating evidence shows that activation of the NOD-like receptor protein 3 (NLRP3) inflammasome contributes to the pathogenesis of neuropathic pain, although the role of the NLRP3 inflammasome in neuropathic pain has not yet been fully elucidated. In animal models of neuropathic pain, paeoniflorin (PF) was shown to have analgesic, anti-inflammatory, and antidepressant effects. ⋯ We found that activation of the NLRP3 inflammasome mediated the development of neuropathic pain following chronic constriction injury of the sciatic nerve and that PF attenuated neuropathic pain by inhibiting NLRP3 inflammasome activation. Moreover, PF enhanced the translocation of the transcription factor nuclear factor erythroid 2-related factor 2 into the nucleus and suppressed nuclear factor-kappa B activity in the spinal cord. These results suggest that PF may be a potential therapeutic agent for neuropathic pain.

Somatosensory dysfunction related neuropathic pain component affects disease activity, functional status and quality of life in ankylosing spondylitis.
To investigate the neuropathic pain (NP) component in ankylosing spondylitis (AS) and to assess the relations between NP and disease characteristics. ⋯ Our results revealed that the presence of NP component in patients with AS is associated with various disease-related variables, including pain, high disease activity, reduced mobility of the axial skeleton, depression and poor quality of life.

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.
