Optimizing Stimulation in a Case of Facial Pain Through "Cross-Talk" of Peripheral and Central Leads: A Case Report.
To describe inter-lead (cross-talk) stimulation between a trigeminal nerve lead and a cervical epidural lead for the treatment of facial pain in a 69-year-old patient with empty nose syndrome. ⋯ Cross-talk configuration between a peripheral and a central lead created a more efficient stimulation technique. The resulting paresthesia was superior to that obtained from either lead alone and exceeded the paresthesia obtained from the combination of the two leads when used simultaneously, without an inter-lead configuration.

Case Reports
NonInfectious Peri-Electrode Edema and Contrast Enhancement Following Deep Brain Stimulation Surgery.
Dramatic radiographic abnormalities seen after electrode placement (DRAAEP) in deep brain stimulation (DBS) surgery is rare and it has not been associated with infection or hemorrhage. It has consisted of peri-electrode low-attenuation signals on CT scans and extensive T2-hyperintense signals without associated contrast enhancement (CE) on MRI scans. ⋯ To our knowledge, this is the first reported case of DRAAEP with positive gadolinium enhancement. Despite the extensive contrast enhancement, these DRAAEP appear to remain benign transient events that, in the absence of clinical signs of infection or neurologic decline, may warrant no further aggressive intervention such as hardware removal.
