Pathomorphological Diagnostic Criteria for Focal Cortical Dysplasias and Other Common Epileptogenic Lesions-Review of the Literature.

Focal cortical dysplasia (FCD) represents a heterogeneous group of morphological changes in the brain tissue that can predispose the development of pharmacoresistant epilepsy (recurring, unprovoked seizures which cannot be managed with medications). This group of neurological disorders affects not only the cerebral cortex but also the subjacent white matter. This work reviews the literature describing the morphological substrate of pharmacoresistant epilepsy.

Mesenchymal Stem Cells Derived and Cultured from Glioblastoma Multiforme Increase Tregs, Downregulate Th17, and Induce the Tolerogenic Phenotype of Monocyte-Derived Cells.

Mesenchymal stem cells (MSCs) possess immunosuppressive properties and have been described in the tumor microenvironment of glioblastoma multiforme (GBM). This manuscript has two major topics-first, to describe isolated and cultured MSCs derived from GBM (GB-MSCs) and second, to examine their immunosuppressive capacity. Our results display cells with morphology and phenotype, clonogenic ability, and osteogenic potential, typical for MSCs.

Cultured Cells Isolated from CNS Indolent B-Cell Lymphoma Have Characteristics of Mesenchymal Stem Cells: A Clinical Case and Scientific Research.

The case report presented here describes the culturing and characterization of mesenchymal stem cells (MSCs) isolated from a primary indolent B-cell lymphoma, located in the CNS of an immunocompetent patient. The presence of such cells in the tumor mass can further elucidate the pathogenesis of the disease and reveal possible future approaches for its treatment. We present a case report of a 61-year-old immunocompetent woman who had an episode of confusion with numbness in the right leg and the right arm, slurred and dysarthric speech and urine incontinence.

Optic Nerve Glioma in Two Sisters with Family History of Neurofibromatosis Type 1.

Optic nerve glioma (ONG) is associated in 10% of patients with neurofibromatosis (NF) type 1. To date no consensus has been reached regarding the therapeutic approach and prevention of visual impairment in these patients. Reports in the literature vary from a conservative approach (observation) to the use of single treatment modalities or multimodality protocols of surgical removal, radiotherapy, and/or chemotherapy.

Metachronous Development of Meningothelial Meningioma, Basal Cell Carcinoma, and Glioblastoma Multiforme in a Patient with Pancreatic Incidentaloma.

We report the unique case of a 61-year-old male patient with known pancreatic incidentaloma who additionally developed 3 other histologically different tumors: left sphenoid wing meningothelial meningioma, basal cell carcinoma of the occiput, and right occipital lobe glioblastoma multiforme. The latter were totally removed with a favorable clinical outcome. The patient's family history was unremarkable, and no data on any previous head and neck irradiation were found.

Infrared Thermography in Surgery of Newly Diagnosed Glioblastoma Multiforme: A Technical Case Report.

Infrared thermography (IRT) is a real-time non-contact diagnostic tool with a broad potential for neurosurgical applications. Here we describe the intraoperative use of this technique in a single patient with newly diagnosed glioblastoma multiforme (GBM). An 86-year-old female was admitted in the clinic with a 2-month history of slowly progressing left-sided paresis.

Cells isolated from human glioblastoma multiforme express progesterone-induced blocking factor (PIBF).

Glioblastoma multiforme (GBM) is the most common and malignant tumor in the central nervous system. One of the contemporary hypotheses postulates that its pathogenesis is associated with the cancer stem cells (CSCs) which originate from mutations in the normal neural stem cells residing in their specific "niches." Simultaneously with its aggressive development the tumor suppresses the local immune system by different secreted and/or cell expressed factors.

Chiari type II malformation: a case report and review of literature.

Introduction: Herniation of cerebellar vermis through the foramen magnum, internal hydrocephaly and spina bifida cystica are the major signs of Chiari type II malformation. Spina bifida cystica (1 in 2000 neonates) is very often the first clinical manifestation of the disease.

Aim: To discuss the pathomorphology, clinical picture and possible treatment of this underestimated malformation.
