Fractures of the thoracolumbar spine complicating ankylosing spondylitis.
In this clinical review of ankylosing spondylitis, the authors emphasize the fragility of the spine and the degree of neurological deficit that can result from minor injury. The management of thoracolumbar fractures complicating ankylosing spondylitis is discussed. ⋯ Patients with ankylosing spondylitis are at risk of injury, particularly extension fractures of the thoracic and lumbar spine. The incidence of trauma-induced neurological deficit is by no means negligible. Management consists of surgery in patients with vertebral instability and neural compression, and recumbency in those with stable fractures.

Case ReportsDe novo formation and rupture of an aneurysm. Case report.
The authors describe a case of de novo formation and rupture of an aneurysm located at the junction of the left internal carotid artery and the superior hypophyseal artery in a middle-aged woman 2 months after another aneurysm, located on the anterior communicating artery, had been clipped. This case is rare because of the short interval between the last angiographic study performed at the first operation and the diagnosis of the de novo aneurysm; in this case the interval was only 47 days, compared with other cases in the literature in which the intervals were 3 to 34 years. Aneurysms can enlarge considerably in 2 to 4 weeks and can rupture at or soon after their formation. This case provides insight into aneurysm formation and rupture.

Randomized Controlled Trial Clinical TrialEffects of decreasing endotracheal tube cuff pressures during neck retraction for anterior cervical spine surgery.
The authors' goal was to determine whether the incidence of postoperative sore throat, hoarseness, and dysphagia associated with anterior spine surgery is reduced by maintaining endotracheal tube cuff pressure (ETCP) at 20 mm Hg during the period of neck retraction. ⋯ The results of this study suggest the following three predictors of postoperative throat discomfort following anterior cervical spine surgery in which neck retraction is performed: increased ETCP during neck retraction (sore throat), neck retraction time (dysphagia), and female sex (sore throat and hoarseness). The simple maneuver of decreasing ETCP to 20 mm Hg may be helpful in improving patient comfort following anterior cervical spine surgery.

Case ReportsLate recovery following spinal cord injury. Case report and review of the literature.
The authors of this prospective, single-case study evaluated the potential for functional recovery from chronic spinal cord injury (SCI). The patient was motor complete with minimal and transient sensory perception in the left hemibody. His condition was classified as C-2 American Spinal Injury Association (ASIA) Grade A and he had experienced no substantial recovery in the first 5 years after traumatic SCI. ⋯ The primary novelty of this report is the demonstration that substantial recovery of function (two ASIA grades) is possible in a patient with severe C-2 ASIA Grade A injury, long after the initial SCI. Less severely injured (lower injury level, clinically incomplete lesions) individuals might achieve even more meaningful recovery. The role of patterned neural activity in regeneration and recovery of function after SCI therefore appears a fruitful area for future investigation.

Multicenter Study Comparative StudyRegional differences in patient characteristics, case management, and outcomes in traumatic brain injury: experience from the tirilazad trials.
Regional differences have been shown in patient characteristics and case management within multiple unselected series of patients suffering from traumatic brain injury (TBI). One might expect that such regional heterogeneity would be small in a more selected population of a randomized clinical trial. The goal of this study was to examine what regional differences in patient characteristics, case management, and outcomes exist between continents and among countries within a patient population included in a randomized clinical trial. ⋯ Despite the use of a strict study protocol, considerable differences in patient characteristics and case management exist between continents and among countries, reflecting variations in social, cultural, and organizational aspects. Outcomes of TBI may be worse in Europe compared with North America, but this finding requires further study.
