To evaluate the risk factors, type, and frequency of complications during video-EEG monitoring with subdural grid electrodes. ⋯ Invasive monitoring with grid electrodes was associated with significant complications. Most of them were transient. Increased complication rates were related to left-sided grid insertion and longer monitoring with a greater number of electrodes (especially more than 60 electrodes). Improvements in grid technology, surgical technique, and postoperative care resulted in significant reductions in the complication rate.

To survey brain death criteria throughout the world. ⋯ There is uniform agreement on the neurologic examination with exception of the apnea test. However, this survey found other major differences in the procedures for diagnosing brain death in adults. Standardization should be considered.

To test the contribution of neurogenic inflammation and neuropeptide release to the pathophysiology of complex regional pain syndrome (CRPS). ⋯ Increased systemic CGRP levels in patients with acute CRPS suggest neurogenic inflammation as a pathophysiologic mechanism contributing to vasodilation, edema, and increased sweating. However, pain and hyperalgesia, in particular in chronic stages, were independent of increased neuropeptide concentration.
