Transcutaneous Electrical Nerve Stimulation in Treatment of Occipital Neuralgia: A Case Report.
Occipital neuralgia is the third most common headache syndrome after migraine and tension type headaches. There is no well-established treatment regimen for a reliable cure. The current case presents a 39-year-old woman, diagnosed with occipital neuralgia of idiopathic cause. ⋯ The patient was started on conventional transcutaneous electrical nerve stimulation, 3 sessions per week. After the procedure, the patient achieved significant pain relief: 1-2/10 on the numeric rating scale, pain initially being 10/10. With maintenance therapy consisting of physical therapy, deep tissue massage, and muscle relaxants, 12 months after starting transcutaneous electrical nerve stimulation therapy, she is pain free.

A trial of spinal cord stimulation (SCS) is a prerequisite to determine efficacy of the therapy prior to placement of a permanent implanted system. A trial may be conducted employing a percutaneously placed temporary cylindrical lead or via a permanently anchored cylindrical lead placed and subsequently secured via open surgical method. There has been little investigation comparing the two methods of trial. This study is a comparative analysis of the two methods both for prediction of success as well as associated morbidity. ⋯ The percutaneous temporary lead trial group was associated with fewer false positives and wound related complications as compared to permanent anchored lead trial group. There was very little technical advantage of routinely anchoring the trial lead.

The management of neuropathic pain and pain related to bone vaso-occlusive crises in sickle cell disease remains challenging in children. Lidocaine 5% patches are recommended in adults for neuropathic pain treatment, but they are not recommended in children. The purpose of this study was to assess the efficacy and tolerance of lidocaine 5% patches in pediatric inpatients. ⋯ Although lidocaine 5% patches decreased the pain's intensity in nearly half of the enrolled patients with an excellent tolerance, the efficacy endpoint was not reached. Further studies should consider a more refined selection of the experimental population to assess the efficacy of lidocaine 5% patches in the pediatric population.

Interferon regulatory factor 8 (IRF8), which is induced by peripheral nerve injury (PNI), plays a key role in activating spinal microglia to release inflammatory cytokines in a p38-dependent way, thereafter results in formation of central sensitization. Pulsed radiofrequency (PRF) on dorsal root ganglion (DRG) alleviates neuropathic pain and inhibits the microglial activation in chronic constriction injury (CCI) rats. However, the consequences of PRF on spinal IRF8 of CCI rats remains unknown. ⋯ Neuropathic pain, pulsed radiofrequency, dorsal root ganglion, microglia, p38MAPK, Interferon regulatory factor 8, chronic constriction injury of sciatic nerve.
