Treatment for brain gliomas is a combined approach of surgery, radiation therapy and chemotherapy. Nevertheless, high-grade gliomas usually recur despite treatment. Ionizing radiation therapy to the central nervous system may cause post-radiation damage. Differentiation between post-irradiation necrosis and recurrent glioma on the basis of clinical signs(More)
Epilepsy surgery has been proposed as a safe alternative treatment for intractable epilepsy in children, especially for patients with structural brain abnormalities. We studied 24 consecutive children who underwent surgery for intractable epilepsy. There were 12 males and 12 females. The mean age was 6.5 years. The seizures' duration ranged from 6 months to(More)
AIM We investigated the angiogenesis and density of newly formed blood vessels in embryonal tumors in relation to Ki-67, bcl-2, p-53 and p-27 expression. METHODS Forty-five children with embryonal tumors were enrolled in the study. Forty patients had a medulloblastoma (MB) and 5 patients had atypical teratoid/rhabdoid tumor (AT/RT). RESULTS In MB, the(More)
Among factors regulating the splicing of major importance is serine/arginine protein kinase 1 (SRPK1) that phosphorylates SR splicing factors. SRPK1 is expressed in the mammalian central nervous system in a region- and neuron-specific manner. Based on previous observations that glial cells are practically devoid of SRPK1 and reports showing aberrant(More)
OBJECTIVE Assessment of the grade and type of glioma is of paramount importance for prognosis. Tumour proliferative potentials may provide additional information on the behaviour of the tumour, its response to treatment and prognosis. The purpose of this study was to investigate the correlation between diffusion tensor imaging (DTI), dynamic susceptibility(More)
INTRODUCTION Abnormalities in blood coagulation are relatively common after traumatic brain injury (TBI). We prospectively studied the safety of the early antithrombotic prophylaxis with low molecular weight heparin. METHODS We prospectively evaluated 61 patients with moderate TBI. Patients requiring surgical treatment and/or with injuries in other(More)
Dandy-Walker malformation is a congenital disorder that involves the cerebellum and fourth ventricle. Regarding treatment, there is still controversy over the optimum surgical management. In the current study, we present 19 consecutive cases of Dandy-Walker malformation diagnosed between January 1992 and January 2008 that were treated in our institute. All(More)
