Age effects on long-term neuropsychological outcome in paediatric traumatic brain injury.

In order to investigate the relationship between age at injury and long-term neuropsychological impairment, 29 children and adolescents who sustained traumatic brain injury (TBI) were studied at least 6 years post-trauma. Tests of intellectual, memory, visuospatial and frontal lobe functions were administered to patients and 29 normal matched control subjects. Correlations between performance on neuropsychological tests and age showed the following direction: the younger the child when TBI was sustained, the worse the cognitive outcome. After controlling for injury severity, visuospatial functions remained related to age. Patients' performance differed significantly from that of controls in half of the neuropsychological variables analysed. To further investigate the effects of age at injury, the sample was divided in two groups (TBI before and after age of 8) and then compared with their respective controls. Patients damaged earlier presented impaired intellectual and visuospatial functions. The results suggest that neuropsychological sequelae remain after at least 6 years of evolution, and that there is an age at injury effect.

[Intraventricular meningiomas].

Eight cases of surgically intervened intraventricular meningiomas are presented. The patients were six males and 2 females with a mean age of 41.7 years (11-70). The length of symptoms was of several months in 6 (75%) of the cases. The most frequent symptoms observed were cephalea and alterations of the upper functions which were presented in six and four cases, respectively. Papilloedema and involvement of long pathways were the most usual findings observed in neurological examination. Diagnosis was made by computerized tomography and angiography in all the cases. Surgery using a transtemporal approach was carried out in six patients and in the other two a parietal-occipital route was used. Two patients were dead and other two presented bilateral amaurosis. The other patients had good postsurgery.

Improving survival of medulloblastoma: results in two groups of patients.

This retrospective study compares the results obtained in 56 children with medulloblastoma treated with two different protocols at our center between 1975 and 1990. Since 1985 we have been enrolled in the medulloblastoma SIOP II protocol in which we have entered 27 patients. These patients from the SIOP group (SG) and the 29 children treated before 1985, the historical group (HG). When the two groups were compared for age and sex distribution, no differences were found; however, prognostic factors were worse in the HG than in SG: 21 versus 15 T3-T4 and 13 versus 8 high-risk, respectively. The relapse rate was 63% for the HG and 39% for the SG. Five-year disease-free survival was 31% for the HG and 56% for the SG (p = 0.037). Five-year survival was 52 and 70%, respectively (p = 0.055). When SG and HG were compared by stratifying for tumor size, surgical resection and the risk variable, better disease-free survival was obtained in SG than in HG. In a multivariate analysis, the HG and the high-risk proved to be variable independent predictors of poor survival. We observe an increase in survival in our patients with medulloblastoma.
