Acupuncture is being used for treatment of cancer-related symptoms in numerous settings, yet empirical evidence supporting the effects of acupuncture in this setting is lacking. Group acupuncture is an economical way to provide acupuncture to patients at a reduced cost. ⋯ The results of this study provide evidence to support the efficacy of group acupuncture for pain, neuropathy, and digestive problems in persons with cancer. A minimum of four weekly treatments may be necessary before improvements are noted. Limitations include a retrospective design, incomplete symptom evaluation, and possible response bias. Future studies of group acupuncture for cancer-related symptoms should utilize a prospective, controlled design, use validated measures to thoroughly evaluate targeted symptoms, and include a more racially and ethnically diverse sample.

Neuropathic pain (NP) is characterized by persistent pain, tactile allodynia, or hyperalgesia. Peripheral nerve injury contributes to rapid progress of inflammatory response and simultaneously generates neuropathic pain. Hydrogen (H2) has anti-inflammation, anti-apoptosis, and anti-oxidative stress effects. ⋯ H2 improved HO-1 mRNA and protein expression and activities in the process of pain. SnPP-IX reversed the inhibitory effect of H2 on hyperalgesia and allodynia and on pro-inflammatory cytokines in DRG and the spinal cord. The antinociceptive and anti-inflammatory effects of H2 were involved in the activation of HO-1/CO signaling during neuropathic pain in rats.

Mice undergoing neuropathic pain induce anxiogenic-like effects and hypernociception in cagemates.
Rodents can recognize pain-related responses in conspecifics. Therefore, cohabitation with a conspecific animal with chronic pain can potentially promote a stressful situation, which can trigger behavioral changes such as anxiety and depression and alter nociceptive responses. In this study we investigated the effect of cohabitation with a mouse undergoing sciatic nerve constriction (neuropathic pain model). ⋯ After 14 days, the cagemates were evaluated using behavioral tests. Social interaction with a conspecific undergoing constriction of the sciatic nerve induced hypernociception and increased anxiety-related responses, whereas in depression tests inconclusive responses and no changes in corticosterone levels were found. In conclusion, cohabitation with suffering conspecifics induces changes in nociceptive responses, as well as in affective responses including anxiety.

Case ReportsSpinal Cord Stimulation for Refractory Neuropathic Pain of Neuralgic Amyotrophy.
The aim of this paper was to report the effect of temporary and chronic spinal cord stimulation for refractory neuropathic pain in neuralgic amyotrophy (NA). A 35-year-old female presented with two-months history of a severe, relentless neuropathic pain of the left shoulder, forearm, palm, and fingers. The neuropathic pain was refractory to various medical treatments, including nonsteroidal anti-inflammatory drugs, opiates, epidural and stellate ganglion blocks, and typically unrelenting. ⋯ Permanent stimulation was given with paddle lead. The neuropathic pain in her NA persisted and she continued using the spinal cord stimulation with 12 months after development of NA. The temporary spinal cord stimulation was effective in a patient with an extraordinary prolonged, acute painful phase of NA attack, and the subsequent chronic stimulation was also useful in achieving an adequate analgesia during the chronic phase of NA.

This article, without presuming to be comprehensive, gives a brief outline of the development of research on neuropathic pain in Germany. Current clinical research on this subject focusses on the validation of human models, patient phenotyping, mechanism-based classification and treatment as well as on molecular pathomechanisms. ⋯ In parallel, basic research achieved international top levels through the development of innovative methods. Close cooperation, building of consortia and European networking made major contributions to the success of this research.
