Review Comparative Study Clinical Trial
Surgery for acute subaxial traumatic central cord syndrome without fracture or dislocation.
Twenty-two patients with subaxial acute traumatic central cord syndrome (CCS) without fracture or dislocation who underwent surgery between 1995 and 2002 were reviewed, retrospectively. There were 13 males and nine females ranging in age from 24 to 84 years (mean 61.2). Falls were the most common injury (68%), followed by motor vehicle accidents (32%). ⋯ The interval between injury and surgery ranged from 1 to 37 days (mean 8.0). Postoperatively, all patients improved clinically. We conclude that surgical management of subaxial acute traumatic CCS without fracture or dislocation improved neurological status and prevented delayed neurological deterioration in our patients.

Phantom limb pain is an often severe and debilitating phenomenon that has been reported in up to 85% of amputees. Its pathophysiology is poorly understood. Peripheral and spinal mechanisms are thought to play a role in pain modulation in affected individuals; however central mechanisms are also likely to be of importance. ⋯ Quality of life measures indicated a statistically significant improvement. This data supports the role for deep brain stimulation in patients with phantom limb pain. The medical literature relating to the epidemiology, pathogenesis, and treatment of this clinical entity is reviewed in detail.

Spinal cord infarction is a rare entity of varying etiology although most often associated with atherosclerotic aortic disease. Definitive diagnosis of (idiopathic) spinal cord infarction in the acute stage and in the absence of demonstrable predisposing factors is not always possible even with MRI. Diffusion-weighted MRI (dwMRI) may provide valuable information in the evaluation of spinal cord ischemia. ⋯ Apparent diffusion coefficient values were significantly low in the lesion, suggesting cytotoxic edema compatible with acute ischemia. The clinical course and other radiographic findings were also compatible with idiopathic spinal cord infarction. Diffusion-weighted MRI is an important diagnostic tool for examining patients with suspected spinal cord ischemia.

We report a case of massive intracerebral air embolism after cardiopulmonary resuscitation in a patient with a fatal head injury. There was no pneumothorax or extravascular pneumocephalus, however, air was found in the internal carotid artery. Massive cerebral air embolism may occur after entrance of air into the circulatory system via ruptured pulmonary vessels during cardiopulmonary resuscitation.

Alpha2-agonists have been extensively used and studied in anaesthesia and intensive care medicine. A list of benefits includes anxiolysis, blood pressure stabilization, analgesia, anaesthetic sparing effects and sedation without respiratory depression or significant cognitive impairment. ⋯ The two readily available agents, clonidine and dexmedetomidine have already been used in many different anaesthetic situations, for a wide variety of surgical procedures. We believe that both of these alpha2-agonists are useful adjuncts for the management of the neurosurgical patient during surgery, and in the intensive care unit.
