Traumatic brain injury in children and adolescents: psychiatric disorders in the second three months.
Psychiatric disorders may be common after traumatic brain injury (TBI) in children, yet there is a death of prospective studies examining this problem. Fifty children aged 6 to 14, hospitalized after TBI, were assessed soon after TBI regarding preinjury psychiatric, behavioral, adaptive, and family functioning, family psychiatric history status and injury severity. The outcome measure was the presence of a "novel" psychiatric disorder (not present before the injury) during the second 3 months after the injury. ⋯ Severity of injury, family psychiatric history, and family function predicted a novel psychiatric disorder. Among children suffering a mild/moderate injury, those with preinjury lifetime psychiatric disorders were no longer (as they had been in the first 3 months) at higher risk than those without such a lifetime history. Thus, there appeared to be children, identifiable through clinical assessment, at increased risk for novel psychiatric disorders after TBI.

To describe the functional outcome of a select group of patients with severe head injuries who would a priori be assumed to have a dismal outcome and to determine prognostic factors that can be used for effective family counseling and rational utilization of scarce resources. ⋯ Younger patients, particularly those with GCS > 5, have the potential for excellent recovery despite prolonged (> 96 hours) intracranial hypertension. These patients will benefit from continued aggressive ICP and CPP management.

Case Reports Clinical Trial
[Analysis of mild barbiturate-moderate hypothermia therapy on the authors' 152 cases].
Mild barbiturate-moderate hypothermia therapy was established for severe head injury and cerebrovascular disease. This study was conducted on 152 patients from April 1984 through July 1995. In this study were included patients with Glagow Coma Scale score of less than 8 points but those with serious systemic complications and elderly and infantile patients were excluded. ⋯ This therapy was found to be particularly effective for preventing ischemic neurological damage in the vasospasm stage following SAH and severe head injury in young patients. However, this therapy did not prevent pneumonia, cardiac failure, arrhythmia and hypopotassemia from occurring frequently. We conclude that this therapy is contraindicated in the elderly, i.e., those older than 65 years.

Temporal and regional profiles of cytoskeletal protein accumulation in the rat brain following traumatic brain injury.
To characterize the cytoskeletal aberration due to traumatic injury, temporal and regional profiles of changes in immunoreactivity of microtubule-associated protein 2 (MAP2), neurofilament heavy subunit protein (NFH) and heat shock protein 72 (HSP72) were investigated after different magnitudes of traumatic brain injury by fluid percussion. The experimental rat brain was perfusion-fixed at 1, 6 and 24 hours after traumatic brain injury. Conventional histological staining has demonstrated that the mildest traumatic brain injury (1.0 atm) induced no neuronal loss at the impact site and that neuron loss was apparent when traumatic brain injury was increased to 4.3 atm. ⋯ Six and 24 hours after the injury, perikaryal accumulation of neurofilament was observed, and the accumulated neurofilament was mostly phosphorylated. These results indicate that the severe traumatic brain injury of 4.3 atm triggers the abnormal accumulation of cytoskeletal proteins in neuronal perikarya, most probably due to an impairment of axonal transport. It is implied that the increased expression of HSP72 may be involved in the protective process of neurons after traumatic brain injury.
