To assess the outcome of two-stage sacral neuromodulation (SNM) in men with chronic urinary retention (CUR) and factors affecting the response. ⋯ Stage-1 SNM was successful in 66.7% of male patients with CUR. Once stage-2 was performed, successful voiding was maintained until the battery needed to be replaced. SNM success was better in men under a median age of 43 years. Further studies are encouraged to study this group of patients.

Randomized Controlled Trial Multicenter Study
Analysis of adverse events in the management of chronic migraine by peripheral nerve stimulation.
In this study, we analyze device- and procedure-related adverse events (AEs) from a recent prospective, multicenter, double-blinded controlled study that utilized peripheral nerve stimulation (PNS) of occipital nerves for management of chronic migraine. ⋯ Implantation of the IPG closer to the lead location was associated with reduced AEs. PNS is a relatively new procedure, and the skill and precision in performing these procedures improves with experience. Our results demonstrate that as the implanter gains more experience with these procedures, a significant reduction in device- and procedure-related AEs may be expected.

Randomized Controlled Trial
Reducing transcranial direct current stimulation-induced erythema with skin pretreatment: considerations for sham-controlled clinical trials.
Transcranial direct current stimulation (tDCS)-induced erythema (skin reddening) has been described as an adverse effect that can harm blinding integrity in sham-controlled designs. To tackle this issue, we investigated whether the use of topical pretreatments could decrease erythema and other adverse effects associated with tDCS. ⋯ Ketoprofen 2% topical pretreatment might be an interesting strategy to reduce tDCS-induced erythema and might be useful for blinding improvement in further sham-controlled tDCS trials.

Spinal cord stimulator (SCS) systems are implanted to treat pain conditions such as neuropathic, radicular, and ischemic pain syndromes. Prior to July 2013, SCS systems were not magnetic resonance imaging (MRI) compatible due to the risk of thermal injury at the site of the leads and generator. Although there are some case reports of patients undergoing MRI studies with SCS systems in place, these stimulators are frequently explanted when clinical care has necessitated an MRI. The purpose of this case series is to discuss the role of SCS explantation in order to acquire an MRI. ⋯ During the time between 2001 and 2011, 199 patients were identified who underwent a thoracic or lumbar SCS implant after a successful trial. Among 199 implants, 33 devices were explanted, and of these, four were explanted due to the primary need for an MRI scan.

Randomized Controlled Trial Multicenter Study Observational Study
Cost-Effectiveness and Cost-Utility Analysis of Spinal Cord Stimulation in Patients With Failed Back Surgery Syndrome: Results From the PRECISE Study.
To assess the cost-effectiveness and cost-utility of Spinal Cord Stimulation (SCS) in patients with failed back surgery syndrome (FBSS) refractory to conventional medical management (CMM). ⋯ Our results suggest that in clinical practice, SCS+CMM treatment of FBSS patients refractory to CMM provides good value for money. Further research is encouraged in the form of larger, long-term studies.
