Excitatory amino acids (EAA), mainly glutamate and aspartate, are released in excessive amounts from terminals of ischemic or traumatically injured neurons. These excessive levels of EAAs initiate a cascade of events believed to lead to secondary delayed damage to the surrounding brain. The N-methyl-D-aspartate receptor antagonists MK-801 and ketamine are(More)
OBJECTIVE Our purpose was to reassess the effectiveness of phenol 4% in aqueous solution for neurolysis in patients with severe chronic nonmalignant pain syndromes who did not achieve adequate pain control (visual analog scale [VAS] <or=3) with conventional pain treatment. DESIGN Forty-two patients with severe nonmalignant pain persisting for 6 months or(More)

Because pain caused by sacroiliac joint dysfunction can mimic discogenic or radicular low back pain, we assumed that the diagnosis of sacroiliac joint dysfunction is frequently overlooked. To assess the incidence of sacroiliac joint dysfunction in(More)
OBJECTIVE This study examined (1) whether two previously reported, well-established models in rats, one a model of hemorrhagic hypotension and the other a model of closed head trauma, could be combined to evaluate neurologic outcome when hemorrhage occurs subsequent to head injury, and (2) the ability of the traditional, conservative approach to fluid(More)
