Case Reports
The use of laminectomy for the placement of a percutaneous spinal cord stimulation electrode.
The placement of a percutaneous electrode for trial stimulation to evaluate the effectiveness of spinal cord stimulation can be impossible because of epidural adhesions from previous spinal surgeries. The authors would like to describe a combination of techniques in order to place a percutaneous lead for a test phase. ⋯ This case demonstrates the possibility to use a combination of an open and percutaneous technique for trial spinal cord stimulation in patients with prior operations in the target area of stimulation.

Repositioning of supraorbital nerve stimulation electrode using retrograde needle insertion: a technical note.
With growing interest and acceptance of peripheral nerve stimulation (PNS) approach, there is now an increasing need in developing clear procedural details to resolve frequent complications and minimize associated tissue injury. Migration and suboptimal positioning of PNS electrodes are one of the most commonly observed complications of PNS approach. ⋯ This technically simple approach to repositioning of cylindrical supraorbital electrodes using retrograde needle insertion eliminates the need for a more elaborate and invasive procedure. The technique can be used for electrode repositioning in most PNS applications.

Case Reports
Abdominal angina due to obstruction of mesenteric artery treated with spinal cord stimulation: a clinical case.
Abdominal angina occurs in patients affected by mesenteric artery obstruction, causing postprandial episodes of visceral pain. The conventional treatment consists of vessels revascularization, but sometimes this is not applicable. ⋯ Spinal cord stimulation may be considered for abdominal angina, although there is still no evidence provided by controlled studies.

Cerebrovascular hypoxia results in severe impairment and electrical dysfunction of cortical and thalamic neuronal networks. Typically cellular electrical activity returns if reoxygenation is established within 5-8 min. Electrical stimulation has been shown to reduce cellular apoptosis following cerebral hypoxia in animal models and clinical case reports. In this study, we wanted to analyze the electrophysiological repercussions of electrical stimulation on recovery of spontaneous thalamocortical oscillations (TCOs) following hypoxia in a thalamocortical slice preparation. ⋯ High-frequency cortical stimulation accelerated the recovery of thalamocortical network activity following hypoxia and reperfusion. Insight into the underlying mechanisms of this effect may enhance therapeutic interventions related to hypoxia following ischemic stroke.
