To estimate the potential benefit of increasing bicycle helmet use among children and adolescents in the United States. ⋯ There continues to be a need to advocate for greater use of bicycle helmets, particularly among young children. Helmet design changes should be considered to prevent mouth injuries.

To review our experience with craniocerebral injuries caused by plastic bullets, and to delineate prognostic factors for outcome. ⋯ Plastic bullet-induced craniocerebral injuries carry a lower morbidity and mortality rate compared with other gunshot wounds. However, plastic bullets do incur a significant risk of injury. Their use should be carefully regulated.

Although hypothermic circulatory arrest (HCA) has become routine practice in cardiac surgery, it is associated with substantial neurotoxicity. We tested the hypothesis that increased nitric oxide production during HCA participates in neuronal death. We previously described a canine survival model of HCA that produces a consistent neurologic deficit and histopathologic pattern of selective neuronal death. ⋯ We conclude that neurotoxicity after HCA involves a significant, early induction in neuronal nitric oxide synthase expression in neuronal processes leading to widespread augmented nitric oxide production in the brain.

To identify early prognostic value of brain injury, a comparison was made between computerized tomography (CT) findings, coagulation abnormalities, and clinical features in 51 patients with closed head injury. The patients were divided into three groups according to their plasma level of fibrin-fibrinogen degradation product (FDP): normal group (FDP 10 micrograms/ml or less) in 20 patients; moderately abnormal group (FDP 10-40 micrograms/ml) in 15 patients; and highly abnormal group (FDP 40 micrograms/ ml or more) in 16 patients. Cases with a fatal clinical course were mostly associated with very high FDP level. ⋯ Although severe head injury (GCS 8 or less) was found in 44% of the highly abnormal group and 13% of the moderately abnormal group, normal group only had one case (5%). Very high FDP concentrations were found to be associated with combined hemorrhagic lesions and mass effect on CT scan, but not with a specific localization of brain damage. In summary, the evaluation of coagulation and fibrinolytic function in patients following closed head injury might have both diagnostic and prognostic value.

Head traumas frequently occur in polytrauma patients but are also found as isolated injuries. In our hospital trauma center without a neurosurgical department, in a 21-month period, 489 patients with head/brain trauma were treated. This represents 6.5% of all patients treated in the trauma and reconstructive surgery clinic. ⋯ In patients with intracerebral bleeding, bleeding in the dorsal fossa, injury of brain nerves, carotid artery or sinus cavernosus injuries, frontobasal injuries with liquor fistula or pneumonencephalon, transfer of the patients to specialized neurosurgical centers is indicated. With this selection, we obtained the same results in a trauma center without a neurosurgical department as reported in the literature. This avoids overloading neurosurgical centers with head/brain injury patients.
