To determine the presence of chronic traumatic brain injury in professional soccer players. ⋯ Participation in professional soccer may affect adversely some aspects of cognitive functioning (i.e., memory, planning, and visuoperceptual processing).

Clinical TrialBarbiturate coma may promote reversible bone marrow suppression in patients with severe isolated traumatic brain injury.
Barbiturate coma is employed in brain-injured patients whenever increases in intracranial pressure remain unresponsive to less aggressive therapeutic regimens. Barbiturate-mediated neuroprotection, however, is weakened by an increased infection rate related to barbiturate-induced immunosuppression. Co-administration of barbiturates with antibiotics known to induce bone marrow suppression could, in turn, potentiate barbiturate-mediated immunosuppression. Adverse drug reactions and interactions of thiopental with antibiotics in terms of leukopenia, infection rate, and bone marrow suppression were investigated. ⋯ Barbiturate coma may cause reversible leukopenia and an increased infection rate. Long-term administration of thiopental may also promote reversible antibiotic-induced bone marrow suppression. The mechanisms and site of interaction between thiopental and antibiotics cannot be assessed by the present study and remain to be clarified. However, during and after barbiturate coma, close monitoring of leukocytes and infections and careful selection of antibiotics is required.

Craniotomy with a mechanical twist drill is a standard, minimally invasive procedure in neurosurgery, widely used for the drainage of chronic subdural hematomas and the placement of ventricular drains. Nevertheless, the use of a standard twist drill trephine bears the risk of causing cerebral lesions. ⋯ The described modified mechanical twist drill enables fast, easy, and safe craniotomy without jeopardizing the advantages of a mechanical twist drill. Therefore, it can be recommended particularly for difficult emergency conditions.

Mild-to-moderate reductions in local cerebral blood flow (ICBF) have been reported to occur in rats after moderate (1.7-2.2 atm) fluid percussion brain injury. The purpose of this study was to determine whether evidence for severe ischemia (i.e., mean ICBF < 0.25 ml/g/min) could be demonstrated after severe brain injury. In addition, patterns of indium-labeled platelet accumulation and histopathological outcome were correlated with the hemodynamic alterations. ⋯ These data indicate that multiple cerebrovascular abnormalities, including subarachnoid hemorrhage, focal platelet accumulation, and severe ischemia, are important early events in the pathogenesis of cortical contusion formation after TBI. Injury severity is expected to be a critical factor in determining what therapeutic strategies are attempted in the clinical setting.

Long-term survival of children and adolescents after traumatic brain injury.
To obtain information on long-term mortality risk and life expectancy after traumatic brain injury (TBI), to improve planning and for counseling patients and their families. In contrast to the literature for spinal cord injury and other disabilities, there have been few such reports for TBI. ⋯ The chief predictors of mortality were basic functional skills such as mobility and self-feeding. After the initial high-risk period, mortality risk for TBI was much lower than for similarly functioning persons with cerebral palsy (a comparison group), although after 10 years the two sets of mortality rates had largely converged. For high-functioning persons, life expectancies were only 3 to 5 years shorter than for the general population. By contrast, the remaining life expectancy for those without mobility 6 months after injury was only 15 years.
