Meningiomas are common primary brain tumors. However, they are often complicated by significant peritumoral brain edema, which leads to surgery difficulties and prolonged hospitalization. The aim of this study was to evaluate the presence of mast cells and expression of hypoxia inducible factor-1 (HIF-1) in correlation with the grade of meningioma and(More)
Introduction: Subarachnoidal hemorrhage (SAH) occurring after aneurismal rupture produces an inflammatory response in the cerebral circulation. Tumor necrosis factor (TNF)-α is a major cytokine in this process. Adhesion molecules provide information on inflammatory reactions taking place in the walls of blood vessels. Clinical evidence suggests a role of(More)
BACKGROUND Dietary habits and adequate dietary intake of antioxidants in the diet may be one of the most important environmental factors for the prevention of Multiple Sclerosis (MS). OBJECTIVES The aim of this study was to estimate selenium (Se) concentration, glutathione peroxidase (GSH-Px) activity and total antioxidant status (TAS) in the serum of(More)

BACKGROUND Data regarding the safety of endoscopic skull base exploration are very scarce. With this method, fragile vital structures (cranial nerves, the optic complex, brainstem, hypothalamus or cerebral ventricles) are exposed to direct illumination within a closed space. Also, high-speed drills, cauterization and ultrasonic aspiration deliver a(More)
BACKGROUND In MR spectroscopy, we evaluated cerebral metabolic changes in patients 2-4 years after clipping or endovascular therapy of intracranial aneurysms. MATERIAL/METODHS: A prospective study was conducted in 36 patients after SAH, treated surgically (n=23) or by endovascular embolisation (n=13). Control group consisted of 20 healthy volunteers. The(More)
Meningiomas constitute up to 13% of all intracranial tumors. The predictive factors for meningioma have not been unambiguously defined; however some limited data suggest that the expression of matrix metalloproteinases (MMPs) and vascular endothelial growth factor (VEGF) may be associated with the presence of peritumoral brain edema (PTBE) and worse(More)
BACKGROUND Lateral orbitotomy can be minimalized using contemporary endoscopy. METHODS Anatomy of the temporal fossa/orbital wall junction is described. The attachment of the temporal fascia is cut off from the orbital rim through a 1.5 cm skin incision in the lateral orbital wrinkle. The temporal muscle is detached from the bone to create a space for the(More)
INTRODUCTION Impaired mobility and compromised manual dexterity leading to difficulties with the activities of daily living (ADL) are an inherent part of the clinical picture in diabetes. Hand function in diabetes is influenced by a variety of pathologies: the median nerve, the most important nerve of the hand, can suffer from metabolic disturbances,(More)
BACKGROUND Astrocytic tumors are the primary brain tumors, which often progress to glioblastoma, a highly malignant neoplasm of the central nervous system. There is much new data regarding to the formation and progression of these tumors; however, glioblastoma remains one of the most fatal neoplasms in humans. The aim of the study was to evaluate the role(More)

PURPOSE To indicate the usefulness of modern neurosurgical techniques to remove intraorbital foreign bodies, not removed during primary ophthalmological surgical intervention. PATIENT 1: A 29-year-old man, struck with a bottle, with a piece of glass located at the top of the right orbit. During the primary ophthalmological intervention--orbitotomy accessed(More)
