AI Article Synopsis
- Over 50% of people with brachial plexus avulsion (BPA) experience chronic pain, which can be worse than their functional limitations, and typical pain medications often don’t help.* -
- A review of existing literature found only 13 relevant studies involving 41 patients treated with spinal cord stimulation (SCS) for BPA pain, showing that most experienced improved pain scores.* -
- Two case reports highlight the success of high-frequency SCS in two male BPA patients, but the authors stress the need for more reliable research to better understand the effectiveness of SCS in this context.*
Article Abstract
Background: At least 50% of individuals who suffer a brachial plexus avulsion (BPA) will develop chronic pain, frequently more debilitating than their functional limitations. Similar to other neuropathic pain states, BPA pain is often refractory to pharmacological agents. Despite spinal cord stimulation (SCS) first being used for BPA in 1974, there have been no published literature reviews examining the current evidence of SCS for the treatment of neuropathic pain following BPA. In addition to a clinical review of the literature for this indication, we also share our experience with high-frequency SCS (HF-SCS) for BPA-related pain.
Methods: MEDLINE and EMBASE databases were searched. All published articles including at least one BPA individual treated with SCS for pain treatment were included.
Results: The initial search identified 288 articles, of which 13 met inclusion criteria for a total of 41 patients. These patients were primarily male and underwent SCS with reported improved pain scores.
Case Reports: HF-SCS leads were percutaneously placed in two male patients who suffered BPA from traumatic injuries. At follow-ups of 13 and eight months, respectively, both patients continued to report an improvement in their pain.
Conclusions: Despite published reports showing benefit for pain control in patients with BPA, the overall low quality, retrospective evidence included in this review highlights the need for a rigorous prospective study to further address this indication.

Peripheral neuropathy (PN), the most common complication of diabetes, leads to sensory loss and associated health issues as pain and increased fall risk. However, present treatments do not counteract sensory loss, but only partially manage its consequences. Electrical neural stimulation holds promise to restore sensations, but its efficacy and benefits in PN damaged nerves are yet unknown.

Background: Nerve wraps composed of various autologous and bioengineered materials have been used to bolster nerve repair sites. In this study, we describe the novel use of autologous fascia nerve wraps (AFNW) as an adjunct to epineurial repair and evaluate their effect on inflammatory cytokine expression, intraneural collagen deposition and end-organ reinnervation in rats and use of AFNW in a patient case series.
Methods: Lewis rats received sciatic transection with repair either with or without AFNW, sciatic-to-common peroneal nerve transfer with or without AFNW, or sham surgery (n=14/group).
Mirogabalin as a Therapeutic Option for Neuropathic Pain Emerging Post-Endodontic Treatment: An Observational Study.

Department of Endodontics, Nihon University School of Dentistry, 1-8-13, Kanda-surugadai, Chiyoda-ku, Tokyo, 101-8310, Japan; Division of Advanced Dental Treatment, Dental Research Center, Nihon University School of Dentistry, Tokyo, Japan.
Introduction: We have recently reported the clinical efficacy of mirogabalin for occlusal pain due to post-traumatic trigeminal neuropathic pain (PTTN-occlusal pain) after endodontic treatment according to the International Classification of Orofacial Pain criteria. This study aimed to determine the mirogabalin administration period and timing of dose reduction and suspension for treating this condition based on managing a certain number of cases.
Methods: Patients diagnosed with PTTN-occlusal pain after or during endodontic treatment were included in the study.

Neuropathic pain (NP) is an ineffectively treated, debilitating chronic pain disorder that is associated with maladaptive changes in the central nervous system, particularly in the spinal cord. Murine models of NP looking at the mechanisms underlying these changes suggest an important role of microglia, the resident immune cells of the central nervous system, in various stages of disease progression. However, given the number of different NP models and the resource limitations that come with tracking longitudinal changes in NP animals, many studies fail to truly recapitulate the patterns that exist between pain conditions and temporal microglial changes.
