This is a prospective case-control study that was conducted to determine if the addition of intraoperative powdered vancomycin placed directly into the wounds at the time of closure might decrease the rate of acute postoperative infection after the placement of spinal cord stimulator paddle leads. ⋯ This study indicates that intraoperative powdered vancomycin placed directly into the wounds at the time of closure can produce similar infection rates between the groups of patients requiring a laminectomy vs. a laminotomy for implantation of a thoracic paddle lead. These findings need confirmation by a randomized controlled design study.

The aim of this review is to make specialists in a variety of disciplines familiar with basic aspects of spinal cord stimulation and the role of mathematical modeling in understanding its mechanisms of action and the solution of basic problems. ⋯ In particular the conclusions from several computer simulation studies are relevant and of interest to specialists in many disciplines.

Neurostimulation is one manifestation of neuromodulation of the gastrointestinal (GI) tract. This manuscript reviews the history of neurostimulation of the GI tract with emphasis on current methods of stimulation. ⋯ GI neurostimulation, as a type of neuromodulation, has been demonstrated to function at several locations in the GI tract for a variety of disorders. The future of neurostimulation in the GI tract will likely be influenced by a better understanding of pathophysiology as well as the development of new techniques and devices for neuromodulation.

To compare health-care expenditures over a 12-month horizon for chronic pain patients with implanted intrathecal drug delivery systems (IDDS) who eliminated or continued systemic opioids postimplant. ⋯ Fifty-one percent of patients completely eliminated systemic opioids in the year after IDDS implant. This elimination resulted in a 10% to 17% reduction in yearly inpatient, outpatient, and drug expenditures.

Functional electrical stimulation (FES) has been shown to facilitate the recovery of grasping function in individuals with incomplete spinal cord injury. Neurophysiological theory suggests that this benefit may be further enhanced by a more consistent pairing of the voluntary commands sent from the user's brain down their spinal cord with the electrical stimuli applied to the user's periphery. The objective of the study was to compare brain-machine interfaces (BMIs)-controlled and electromyogram (EMG)-controlled FES therapy to three more well-researched therapies, namely, push button-controlled FES therapy, voluntary grasping (VOL), and BMI-guided voluntary grasping. ⋯ These results provide preliminary evidence suggesting the potential of BMI-FES and EMG-FES to induce greater neuroplastic changes than conventional therapies, although the precise mechanism behind these changes remains speculative. Further investigation will be required to elucidate the underlying mechanisms and to conclusively determine whether these effects can translate into better long-term functional outcomes and quality of life for individuals with spinal cord injury.
