Epilepsy continues to provide challenges to clinicians, as a significant proportion of patients continue to suffer from seizures despite medical and surgical treatments. Neurostimulation has emerged as a new treatment modality that has the potential to improve quality of life and occasionally be curative for patients with medically refractory epilepsy who are not surgical candidates. In order to continue to advance the frontier of this field, it is imperative to have a firm grasp of the current body of knowledge. ⋯ This review shows us how neurostimulation provides us with yet another tool with which to treat the complex disease of medically refractory epilepsy.

This systematic review aimed to determine the efficacy and effectiveness of percutaneous tibial nerve stimulation (PTNS) on symptoms of overactive bladder (OAB) and pelvic organ disorders, pain, adverse events (AEs), and quality of life (QoL). ⋯ This systematic review provides evidence for the efficacy of PTNS on symptoms, pain, and QoL measures of OAB, FI and category IIIB CP/CPP. Evidence of effectiveness was found on symptoms and QoL for OAB. The total amount of seven included studies, from which even the most favorable study has some potential bias, is too small to draw firm conclusions. Independent high quality RCTs are necessary to confirm and delineate the range of therapeutic effects of PTNS in this region. PTNS is a safe intervention.

Current research indicates that chronic peripheral neuropathic pain includes a role for glia and the actions of proinflammatory factors. This review briefly discusses the glial and cytokine responses that occur following peripheral nerve damage in support of utilizing anti-inflammatory cytokine interleukin-10 (IL-10) therapy to suppress chronic peripheral neuropathic pain. SPINAL NONVIRAL INTERLEUKIN-10 GENE THERAPY: IL-10 is one of the most powerful endogenous counter-regulators of proinflammatory cytokine function that acts in the nervous system. Subarachnoid (intrathecal) spinal injection of the gene encoding IL-10 delivered by nonviral vectors has several advantages over virally mediated gene transfer methods and leads to profound pain relief in several animal models. NONVIRAL GENE DELIVERY: Lastly, data are reviewed that nonviral deoxyribonucleic acid (DNA) encapsulated by a biologically safe copolymer, poly(lactic-co-glycolic) acid (PLGA), thought to protect DNA, leads to significantly improved therapeutic gene transfer in animal models, which additionally and significantly extends pain relief. ⋯ The impact of these early studies exploring anti-inflammatory genes emphasizes the exceptional therapeutic potential of new biocompatible intrathecal nonviral gene delivery approaches such as PLGA microparticles. Ultimately, ongoing expression of therapeutic genes is a viable option to treat chronic neuropathic pain in the clinic.

Review Case Reports
Spinal cord stimulation in pregnancy: a literature review.
Currently, the use of spinal cord stimulation (SCS) therapy is not recommended in pregnancy because the effects of SCS on the pregnancy and developing fetus are unknown. However, many SCS recipients are women of childbearing age who may later become pregnant. The purpose of the present report is to review and summarize the existing literature on the use of SCS therapy during the prenatal period. ⋯ Women of childbearing age who are candidates for SCS implantation should be tested for pregnancy prior to implantation surgery. They also should be informed about the limited state of our scientific knowledge regarding the impact of this technology on reproductive health. For patients already implanted with SCS, decisions about ongoing use in the event of pregnancy should be made on an individual basis after a careful consideration of potential risks and benefits.
