Mechano-insensitive ("silent") nociceptors contribute to neuropathic pain. Their activation causes an axon-reflex erythema, but their high electrical excitation thresholds complicate their assessment, particularly in painful neuropathy. We therefore developed electrical stimulation paradigms for brief nociceptor activation and explored their sensitivity for clinical trials. ⋯ Electrical stimulation at high current density using pin electrodes is a sensitive method for investigating "silent" nociceptors, which might therefore preferably be applied in neuropathic pain conditions.

Repetitive Transcranial Magnetic Stimulation for Fibromyalgia: Systematic Review and Meta-Analysis.
Fibromyalgia (FM) is a prevalent chronic pain syndrome with few effective therapeutic options available. Repetitive transcranial magnetic stimulation (rTMS) is an emerging therapeutic alternative for this condition; however, results have been mixed. ⋯ In comparison with sham stimulation, rTMS demonstrated superior effect on the QoL of patients with FM 1 month after starting therapy. However, further studies are needed to determine optimal treatment protocols and to elucidate the mechanisms involved with this effect, which does not seem to be mediated by changes in depression, but that may involve pain modulation. Level of evidence 1b.

Pain assessment and monitoring is a prerequisite for its adequate treatment in patients with cancer. We performed a feasibility study on the use of short message service (SMS) and interactive voice response (IVR) to improve pain management in patients with cancer, including terminally ill patients. ⋯ Monitoring and managing pain with IVR/SMS in patients with cancer at home appeared acceptable and feasible, even in terminally ill patients. The reluctance for actively contacting the professional in case of increased pain intensity is circumvented in this setting. Further research, preferably in a controlled study, is needed to establish the use of this intervention in a larger patient population.
