Leprosy-related multiple mononeuropathy offers a pattern of impairment where neuropathy with and without neuropathic pain (NeP) are present in the same individual, thus allowing to investigate peripheral sensory and innervation in both conditions. This cross-sectional study collected data on clinical and neurological examination, pain assessment questionnaires, quantitative sensory test, and intraepidermal nerve fiber density of patients with leprosy and divided the cohort into 2 groups: with NeP (P+) and without NeP (P-). Furthermore, we assessed mirror body areas in the same NeP individuals with bilateral neuropathy also presenting unilateral NeP. ⋯ As expected, interindividual comparisons failed to show differences in intraepidermal nerve fiber density and subepidermal plexus areas between P+ and P- patients ( P = 0.2980, P = 0.9044; respectively). Higher HPT and lower mechanical detection threshold were related to NeP. This study pointed out the relevance of intraindividual comparisons including mirror areas when assessing local changes in peripheral NeP.

Patients diagnosed with neuropathic pain experience continuous or intermittent spontaneous pain throughout their lives. Pharmacological treatments often provide limited relief; therefore, a multidisciplinary approach should be utilized to manage neuropathic pain. This review examines the current literature on integrative health modalities (anti-inflammatory diets, functional movement, acupuncture, meditation, and transcutaneous therapy) for treating patients with neuropathic pain. ⋯ The use of an anti-inflammatory diet, functional movement, acupuncture, meditation, and transcutaneous therapy in treating neuropathic pain has been investigated in prior literature with positive outcomes. However, there remains a large void in evidence-based knowledge and clinical applicability for these interventions. Overall, integrative health offers a cost-efficient and harmless way of creating a multidisciplinary approach to managing neuropathic pain. There are many complementary approaches to treating neuropathic pain as part of an integrative medicine approach. Research is needed to explore other herbs and spices not yet reported in the peer-review literature. Additionally, follow-on research is needed to understand the clinical applicability of the proposed interventions as well as the dose and timing of the interventions to predict response and duration.

Chemotherapy-induced peripheral neuropathy is a challenging condition to treat, and arises due to severe, dose-limiting toxicity of chemotherapeutic drugs such as paclitaxel. This often results in debilitating sensory and motor deficits that are not effectively prevented or alleviated by existing therapeutic interventions. Recent studies have demonstrated the therapeutic effects of Meteorin, a neurotrophic factor, in reversing neuropathic pain in rodent models of peripheral nerve injury induced by physical trauma. ⋯ Our findings indicate that rmMeteorin has a robust and sustained antinociceptive effect in the paclitaxel-induced peripheral neuropathy model and the development of recombinant human Meteorin could be a novel and effective therapeutic for chemotherapy-induced peripheral neuropathy treatment. PERSPECTIVE: Chemotherapy neuropathy is a major clinical problem that decreases quality of life for cancer patients and survivors. Our experiments demonstrate that Meteorin treatment alleviates pain-related behaviors, and signs of neurotoxicity in a mouse model of paclitaxel neuropathy.

The primary objective of this study was to determine the current rate of lead fracture during temporary percutaneous peripheral nerve stimulator (PNS) lead removal at the Mayo Clinic Rochester Division of Pain Medicine. ⋯ This retrospective review of 50 patients with 80 temporary percutaneous PNS leads implanted for chronic peripheral neuropathic pain resulted in a 6.25% rate of retained lead fragment at the time of lead removal by the provider at the end of 60-day treatment. This fracture and retention rate is consistent with previous published retrospective data on PNS, which has shown a 3% to 21% lead fracture rate during intentional lead removal.

Observational Study
Peripheral Nerve Stimulation on the Brachial Plexus With Ultrasound-guided Percutaneous Technique: A Case Series.
The aim of this case series was to assess the safety and effectiveness of peripheral nerve stimulation (PNS) of the brachial plexus performed using a low invasive percutaneous approach with ultrasound guide. ⋯ PNS systems of the brachial plexus implanted with percutaneous approach appear to be safe and effective in a follow-up period of 18 months. Longer and larger studies are needed to confirm and extend these outcomes.
