This article describes the organization and function of a university-based neurosurgical intensive care unit. The unit's success has been based in part on its physical structure and in larger part on its organization. Patients are comanaged by a team of neurosurgeons and anesthesiologist intensive care specialists, who receive twice-weekly input from all(More)
The mammalian skeleton performs a diverse range of vital functions, requiring mechanisms of regeneration that restore functional skeletal cell populations after injury. We hypothesized that the Wnt pathway specifies distinct functional subsets of skeletal cell types, and that lineage tracing of Wnt-responding cells (WRCs) using the Axin2 gene in mice(More)
We have developed a computer system for use in the operating room and intensive care unit for the automated acquisition and classification of flash evoked potentials. The project goals were to: (1) acquire evoked potentials without user intervention; (2) recognize, label, and trend important parameters; and (3) alarm if parameters deviate too far from(More)
Median nerve somatosensory evoked potentials (SEPs) were monitored in patients with chronic pain before and after stellate ganglion blockade. A change caused by the syndrome or by the block would suggest that SEPs might be useful in the diagnosis and treatment of chronic pain. We observed 20 subjects. Group I (n = 10) had chronic pain not involving the(More)
We present a case report demonstrating that somatosensory evoked potentials (SEPs) suggested ischemia when an internal carotid aneurysm ruptured during surgical clipping. SEPs were also recorded from the contralateral cortex and subcortical and peripheral sites and remained unchanged. The use of multiple bilateral recording sites for SEP recording(More)
