Prospective longitudinal experimental study. ⋯ The findings suggest that the anti-nociceptive effect of dapsone is regulated through the decrease of oxidative stress and the excitotoxicity is associated with the activation of NMDA receptors.Level of Evidence: N/A.

Case Reports
Prevesicular herpes zoster lumbar radiculopathy with transient motor paresis: A case report.
Herpes zoster frequently causes dermatomal vesicular rash accompanied by severe neuralgia, and reaching a differential diagnosis may be challenging before the appearance of the vesicular rash. ⋯ A high index of suspicion is necessary to differentiate early herpes zoster radiculitis before the appearance of vesicular rash from compressive radiculopathy. In L2-3 ipsilateral radiating pain along the dermatome or myotome, the absence of reverse Straight Leg Raise sign may be a possible factor in differentiating herpes zoster radiculitis from compressive radiculopathy.

Spinal cord stimulation (SCS) is an effective treatment in failed back surgery syndrome (FBSS). The effect of neuropathic pain medication use on SCS outcome is poorly understood. ⋯ The use of gabapentinoids was associated with a significantly lower spinal cord stimulator explantation rate and a higher chance of opioid discontinuation or >50% dose reduction. This indicates that patients with SCS could benefit from concomitant use of gabapentinoids. Prospective randomized trials are warranted to verify this hypothesis.

Neuropathic pain (NP) is characterized by the presence of spontaneous pain, allodynia and hyperalgesia. Repetitive transcranial magnetic stimulation (rTMS) is one of neuromodulatory techniques that induces satisfactory NP relief, including that from refractory pain patients. The objective of this study was to evaluate rTMS treatment over long term memory (LTM) and hippocampal BDNF and IL-10 levels in rats submitted to a NP model. ⋯ Biochemical assays (BDNF and IL-10 levels) were performed in hippocampus tissue homogenates. rTMS treatment reversed the reduction of the discrimination index in the ORT and the hippocampal IL-10 levels in NP rats. This result shows that rTMS reverses the impairment LTM and the increase in the hippocampal IL-10 levels, both induced by NP. Moreover, it appears to be a safe non-pharmacological therapeutic tool since it did not alter LTM and neurochemical parameters in naive animals.

It is simple, convenient, inexpensive, proven, extensive, and safe for acupuncture in the treatment of postherpetic neuralgia (PHN). However, there are no comparisons between various acupuncture therapies that can directly and effectively provide specific guidance to clinicians. The development of a guideline for the optimization of acupuncture for PHN is of great importance for the development of clinical acupuncture. Therefore, we attempted to design a study protocol for a network meta-analysis of randomized controlled trials of acupuncture for PHN to provide evidence to support the treatment of acupuncture for PHN. ⋯ This study will provide comprehensive and reliable evidence-based evidence for the treatment of PHN with acupuncture.
