We report our experience regarding evaluation, surgical treatment and outcomes in a population of 21 children with histopathologically confirmed developmental tumours [nine dysembryoplastic neuroepithelial tumours (DNET), ten gangliogliomas (GG) and two gangliocytomas (GC)] and related epilepsy, analyzing video-EEG, MRI and neuropsychological data, before and after surgery. Most children had focal epilepsy correlating well with lesion location. One patient had epileptic spasms and generalized discharges. Tumours were located in the temporal lobe in 13 patients. Mean age at surgery was 11.16 years. Postsurgical MRI showed residual tumour growth in one DNET. One child had a recurrent ganglioglioma with anaplastic transformation. At latest follow-up (mean 4.68 years) 95.2% of patients were seizure-free and no significant neuropsychological declines were observed. Evidence from our study suggests that, in this setting, surgery should be performed before criteria for refractory epilepsy are met, particularly in cases with early seizure onset, in order to optimize cognitive outcome.

Pathologic substrate was the main factor related with seizure outcome. In children with MCD and vascular lesions, although developmental progression is apparent, significant post-surgical improvements are restricted by the severity of pre-surgical neuropsychological disturbances and a slow maturation. Early surgery assessment is recommended to enhance the possibilities for a better quality of life in terms of seizure control, as well as better autonomy and socialization.

The authors report their experience with the use of epsilon aminocaproic acid (EACA) in the preoperative management of a series of patients with ruptured intracranial aneurysms. A similar series of patients was taken as control. They found that EACA is of definite value in preventing recurrent hemorrhage in the preoperative period. The significance of antifibrinolytic therapy in ruptured intracranial aneurysms is discussed.

Conclusions. The study of tumour markers can be used to guide the diagnosis of certain tumours of the pineal region. At present, the recommended procedure involves taking a histological sample of the tumour in order to establish an accurate diagnosis and a specific oncological treatment.
