Epilepsy comprises several syndromes, amongst the most common being mesial temporal lobe epilepsy with hippocampal sclerosis. Seizures in mesial temporal lobe epilepsy with hippocampal sclerosis are typically drug-resistant, and mesial temporal lobe epilepsy with hippocampal sclerosis is frequently associated with important co-morbidities, mandating the(More)
Postsubarachnoid hemorrhage, systemic inflammatory response syndrome and associated organ system failure are more frequently found in patients in poor neurologic condition. Since subarachnoid hemorrhage causes a profound intrathecal inflammatory response with production of proinflammatory cytokines TNFalpha, IL-1beta, and IL-6, a possible explanation for(More)
In Austria, registration of malignant brain tumours is legally mandatory, whereas benign and borderline tumours are not reported. The Austrian Brain Tumour Registry (ABTR) was initiated under the auspices of the Austrian Society of Neuropathology for the registration of malignant and non-malignant brain tumours. All Austrian neuropathology units involved in(More)
OBJECTIVE Frameless stereotactic navigation devices require preoperative application of skin markers (SM) and planning radiography, which limits their even wider use. Therefore, we prospectively studied the applicability and accuracy of anatomic "natural" markers (NM) for image registration. METHODS The accuracy of NM was evaluated in 26 patients operated(More)
The basic questions in the pathogenesis of inflammation in the nervous system are how inflammatory cells reach the brain, where they recognize their antigen, how the nervous system interacts with local immune regulation in the lesion, and how inflammatory cells induce irreversible tissue damage. These questions have been addressed by studying the(More)
To clarify the anatomical organization of human memory remains a major challenge in clinical neuroscience. Experimental data suggest dentate gyrus granule cells play a major role in memory acquisition, i.e. pattern separation and rapid pattern completion, whereas hippocampal CA1 neurons are implicated in place memory and autobiographical memory retrieval.(More)
The expression of leucocyte adhesion molecules was studied on cerebral endothelia by immunocytochemistry. In peritumoral "normal" brain tissue we found low endothelial expression of ICAM1, LFA3, CD44, and CD9, whereas VLA1 was present on vessels in high incidence and density. LFA1, CD2, and CR3 were found on intraluminal and parenchymal leucocytes, but were(More)
Treatment options for leptomeningeal disseminated brain tumors are limited by the lack of effective drugs for intrathecal therapy of non-hematologic malignancies. We report on our experience with an intraventricular therapy consisting of mafosfamide, a preactivated cyclophosphamide derivative, and etoposide. Between May 1994 and 2002, 26 patients aged 2-19(More)
Survivin is a member of a novel protein family of inhibitors of apoptosis, and also plays a role as a potent regulator of mitosis. In semiquantitative Western blot analysis of glioblastomas, survivin expression was shown to be a prognostically significant factor. In the present study we investigated the immunohistochemical expression of survivin and its(More)
BACKGROUND The ideal treatment strategy for low-grade gliomas (LGGs) is a controversial topic. Additionally, only smaller single-center series dealing with the concept of intraoperative magnetic resonance imaging (iMRI) have been published. OBJECTIVE To investigate determinants for patient outcome and progression-free-survival (PFS) after iMRI-guided(More)
