Background: Scrambler therapy (ST) is a relatively new neuromodulation technique that is useful in treatment of medication-resistant pain syndromes, including chemotherapy-induced peripheral neuropathy and other chronic pain syndromes. Amyloidosis commonly leads to peripheral neuropathy, and although the mechanism is unclear, it is possibly related to amyloid deposits on the nerve. Case Presentation: In this case presentation, we describe the novel use of ST for a patient with 13 years of neuropathic pain related to amyloidosis and worsened by chemotherapy. ⋯ Her upper extremities were treated with 4 days of 40 minute ST treatment sessions providing reduction in her pain scores to zero. Discussion: Current therapy for amyloid peripheral neuropathy aims at treating the underlying condition, and then medical management with gabapentinoids. This is first case presentation showing successful treatment with ST.

Voltage-gated Ca2+ (CaV) channels regulate multiple cell processes, including neurotransmitter release, and have been associated with several pathological conditions, such as neuropathic pain. Cdk5, a neuron-specific kinase, may phosphorylate CaV channels, altering their functional expression. During peripheral nerve injury, upregulation of CaV channels and Cdk5 in the dorsal root ganglia (DRG) and the spinal cord, has been correlated with allodynia. ⋯ Likewise, the Cdk5 inhibitor olomoucine affected the rapid and the slow C components of the cAP recorded in the dorsal roots. Patch-clamp recordings revealed an increase in T- and N-type currents recorded in the soma of acute isolated L3-4 sensory neurons after L5-6 SNL, which was prevented by olomoucine. These findings suggest changes in CaV channels location and function in L3-4 afferent fibers associated with Cdk5-mediated phosphorylation after L5-6 SNL, which may contribute to nerve injury-induced allodynia.

Distal sensory polyneuropathy (DSP) is a disabling consequence of human immunodeficiency virus (HIV), leading to poor quality of life and more frequent falls in older age. Neuropathic pain and paresthesia are prevalent symptoms; however, there are currently no known curative treatments and the longitudinal course of pain in HIV-associated DSP is poorly characterized. ⋯ Paresthesias are a clinically significant predictor of incident pain at follow-up among aging PWH with DSP. Development of new therapies to encourage neuroregeneration might take advantage of this finding to choose individuals likely to benefit from treatment preventing incident pain.

Meta Analysis
Acupuncture and moxibustion combined with cupping for the treatment of post-herpetic neuralgia: A meta-analysis.
There are still controversies between the curative effect of acupuncture combined with cupping therapy and western medicine for post-herpetic neuralgia (PHN). Our meta-analysis fully incorporates the research of acupuncture combined with cupping therapy versus Western medicine for PHN, aiming to explore the difference in the efficacy of the 2 therapies, so as to provide guidance for clinical treatment. ⋯ The effect of acupuncture and moxibustion combined with cupping in the treatment of PHN is significantly higher than that of conventional western medicine, and it can significantly prevent the occurrence of PHN. Chinese medicine should be used more widely in the treatment of PHN.
