To present a normative database of hippocampal and temporal horn volume and to clarify the relationship between these measures and cognitive outcome in patients with traumatic brain injury. ⋯ Hippocampal and temporal horn volumes appear to be independent variables in healthy control subjects. Traumatic brain injury results in significant hippocampal atrophy and temporal horn enlargement. The hippocampus and temporal horn volumes were inversely correlated in the group with traumatic brain injury, suggesting a differential relationship of these structures in patients with brain injury as compared with control subjects. In the subacute phase, the volume of the temporal horn may be indicative of intellectual outcome and that of the hippocampus appears to be indicative of verbal memory function.

Traumatic brain injury in children and adolescents: psychiatric disorders in the first three months.
To assess predictive factors of psychiatric outcome in the first 3 months after traumatic brain injury (TBI) in children and adolescents. ⋯ These data suggest that there are children, identifiable through clinical assessment, at increased risk for development of psychiatric disorders in the first 3 months after TBI.

Metabolic quantification of lesion volume following experimental traumatic brain injury in the rat.
A reliable and rapid method for quantifying lesion volume following traumatic brain injury (TBI) has vast potential in brain injury research. Staining with 2, 3, 5-triphenyltetrazolium chloride (TTC) provides for demarcation of damaged or infarcted tissue from normal, viable cerebral tissue, in which a red formazan product is formed by reduction during cellular respiration of mitochondrial dehydrogenase enzymes. The present study evaluated the use of TTC staining to quantify the cortical lesion volume in rats undergoing fluid-percussion (FP) brain injury. ⋯ The mean (+/-SD) lesion volumes were 12.1 (+/-4.5) mm3 following mild injury, 33.8 (+/-8.6) mm3 following moderate injury, and 45.1 (+/-14.0) mm3 following severe injury. A significant difference was observed between all injury groups using a t test with Bonferroni correction (p < 0.05). These results suggest that the TTC staining technique is a useful, rapid, and reproducible method for quantification of lesion volume following lateral FP brain injury.

[Shock room management in severe craniocerebral trauma].
Early clinical management of severe head injury should take place in an emergency resuscitation room and be conducted according to the guidelines of the treatment of severely injured patients with attention given to time. The first phase (with a maximum duration of 30 min) comprises physical examination, stabilisation of vital functions and basic technical diagnostics. With pulmonary and circulatory functions stabilized, the second phase begins with a craniol computed tomography examination followed by adequate therapeutic measures, including, if necessary, the CT-controlled implantation of an intracranial pressure catheter.
