Sunday, March 23rd, 2008Recurrent transient global amnesia with intrathecal baclofen. A middle-aged woman began experiencing spells of profound anterograde amnesia several months after beginning intrathecal baclofen treatment for generalized dystonia. Her spells met criteria for transient global amnesia, but were unusual because of their frequent recurrence and because their ...

Sunday, March 23rd, 2008Intravascular injection in lumbar medial branch block: a prospective evaluation of 1433 injections. BACKGROUND: The successful outcome and validity of lumbar medial branch block (MBB) are largely dependent on technique accuracy. Intravascular uptake of injectate causes a false-negative response to block and is associated with various ...
A prospective randomized trial on the role of perioperative celecoxib administration for total knee
Sunday, March 23rd, 2008A prospective randomized trial on the role of perioperative celecoxib administration for total knee arthroplasty: improving clinical outcomes. BACKGROUND: Total knee arthroplasty (TKA) is associated with considerable postoperative pain, which, if unrelieved, may result in prolonged hospital stay, inability to participate in rehabilitation programs, poor outcomes, ...
Chronic phantom limb pain: the effects of calcitonin, ketamine, and their combination on pain and se
Sunday, March 23rd, 2008Chronic phantom limb pain: the effects of calcitonin, ketamine, and their combination on pain and sensory thresholds. BACKGROUND: Calcitonin was effective in a study of acute phantom limb pain, but it was not studied in the chronic phase. The overall literature on N-methyl-D-aspartate antagonists is equivocal. ...
Single-dose dexamethasone reduces dynamic pain after total hip arthroplasty.
Sunday, March 23rd, 2008Single-dose dexamethasone reduces dynamic pain after total hip arthroplasty. BACKGROUND: Preoperative glucocorticoids reduce postoperative nausea but may also improve analgesia and decrease opioid consumption. METHODS: Fifty consecutive patients undergoing elective, unilateral, primary total hip arthroplasty under spinal anesthesia with propofol sedation received in a randomized, double-blind, ...
Desflurane affords greater protection than halothane in the function of mitochondria against forebra
Sunday, March 23rd, 2008Desflurane affords greater protection than halothane in the function of mitochondria against forebrain ischemia reperfusion injury in rats. BACKGROUND: Halothane and desflurane have been shown to attenuate neuronal injury; however, the effects of these anesthetics on mitochondria are unclear. We investigated whether halothane and desflurane affect ...
