To screen for potentially underreported behavioral changes in patients with idiopathic Parkinson's disease (PD) pre- and post-deep brain stimulation (DBS), a retrospective data base review was performed. ⋯ Many of the neuropsychiatric issues were identified at preoperative baseline and their overall occurrence was more than expected. There was a potential for worsening of these issues post-DBS. There were subtle differences in time course, and in unilateral vs. bilateral implantations. Clinicians should be aware of these potential behavioral issues that may emerge following DBS therapy, and should consider including screening questions in preoperative and postoperative interviews. Standardized scales may miss the presence or absence of these clinically relevant issues.

Clinical Trial
Combined spinal cord and peripheral nerve field stimulation for persistent post-herniorrhaphy pain.
Chronic post-hernia pain is a common complication after inguinal herniorrhaphies. Peripheral nerve field stimulation (PNFS) and spinal cord stimulation (SCS) are two new promising treatment modalities. Four patients with persistent neuropathic post-hernia pain were recruited for this prospective study. ⋯ Both SCS and PNFS are effective in treating post-hernia pain, but the magnitude of pain reduction was more prominent with concomitant stimulation. Combined PNFS and SCS should be considered for patients with a less than optimal response to either SCS or PNFS. More studies are necessary to address the cost-effect issues of this new approach to treatment.

Case Reports
Tripolar spinal cord stimulation for the treatment of abdominal pain associated with irritable bowel syndrome.
The objective of this case report is to describe the use of transverse tripolar dorsal column stimulation in a patient with a history of irritable bowel syndrome (IBS) associated with abdominal pain resistant to conservative treatments. ⋯ The use of the tripolar SCS in this patient provided relief of abdominal and thoracic spine pain, regulated bowel habits, and improved the patient's quality of life. We believe that the use of SCS should be considered as a treatment option in patients with IBS when all conservative treatments failed.

Case Reports
Displacement of a deep brain stimulator lead during placement of an additional ipsilateral lead.
The use of Deep Brain Stimulation (DBS) has been increasing. It follows the premise of neuromodulation in that it is reversible, as compared to previous lesioning procedures. ⋯ This scenario was corrected and had no clinical or functional complication. Placement of an additional ipsilateral DBS lead can be a safe and effective treatment option.

Multicenter Study Clinical Trial
A prospective study of dorsal root ganglion stimulation for the relief of chronic pain.
The article aims to study the safety and effectiveness of dorsal root ganglion (DRG) stimulation with a new device in the treatment of chronic pain. ⋯ These initial results suggest that stimulation of the DRG can reduce pain in those patients suffering from chronic pain. DRG stimulation may offer several potential benefits over other neuromodulation techniques, including the ability to target difficult-to-reach anatomies such as the low back and foot.
