Astrocyte subtype‐specific alterations in the dentate gyrus of individuals with mesial temporal lobe epilepsy

Epilepsia Open, EarlyView.
Abstract Objective Epilepsy affects approximately 50 million people worldwide and, although primarily attributed to neuronal dysfunction, increasing evidence highlights a critical role of glial cells, particularly astrocytes, in the pathophysiological mechanisms.

The FGF/FGFR System in the Biology and Therapeutic Landscape of Pediatric CNS Tumors

Medicinal Research Reviews, EarlyView.
ABSTRACT Central nervous system (CNS) tumors are the most common solid malignancies in children, comprising a highly heterogeneous group of neoplasms defined by distinct molecular alterations and clinical behaviors. Advances in molecular genetics have underscored the relevance of specific signaling pathways in driving pediatric tumorigenesis, among ...

Case Report: A Unique Case of Pediatric Central Nervous System Embryonal Tumor Harboring the CIC–LEUTX Fusion, Germline NBN Variant and Somatic TSC2 Mutation: Expanding the Spectrum of CIC-Rearranged Neoplasia

Frontiers in Oncology, 2020
Central nervous system (CNS) embryonal tumors (WHO grade IV) are a heterogeneous group of rare, poorly differentiated neuroepithelial malignant neoplasms that commonly occur in children, and they have a poor prognosis.

Stem Cell‐Based Approaches for Neurotrophic Keratopathy: From Ocular Surface to Neuro‐Ophthalmology

Sensory Neuroscience, EarlyView.
ABSTRACT Neurotrophic keratopathy is an uncommon, but potentially sight‐threatening, corneal disorder that results from impaired trigeminal sensory innervation. The loss of corneal sensation disrupts epithelial stability, weakens wound healing, and may lead to persistent epithelial defects, stromal ulceration, and, in the most advanced cases, corneal ...

Pebbled mosaic‐like heterogeneous echogenicity in ovarian immature teratomas and correlation of ultrasound patterns with pathological grades

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
This study characterizes heterogeneous mottled grayscale ultrasound echoes of ovarian immature teratoma as the “pebbled mosaic sign,” noting solid lesions correlate with advanced pathological grades. Preoperative identification of immature tissue informs operative stratification. Abstract Introduction Ovarian immature teratomas (ITs) are rare malignant

Astroblastoma – a rare and challenging tumor: a case report and review of the literature

Journal of Medical Case Reports, 2018
Background Astroblastoma is a controversial and an extremely rare central nervous system neoplasm. Although its histogenesis has been clarified recently, controversies exist regarding its cellular origin and validity as a distinct entity.

Patient‐derived surgical samples reveal the cellular and molecular signatures of glioblastoma infiltration in distinct radiological zones

Brain Pathology, EarlyView.
Integrated histological and transcriptional profiling of the glioblastoma periphery reveals clinically relevant tumor infiltration beyond MRI‐defined boundaries. MRI‐guided biopsies from contrast‐enhancing (CE), non‐contrast‐enhancing (nCE), edema (E), and radiologically normal (N) regions demonstrate that nCE areas frequently retain neoplastic and ...

Well-differentiated pediatric glial neoplasms with features of oligodendroglioma, angiocentric glioma and dysembryoplastic neuroepithelial tumors: a morphological diagnostic challenge [PDF]

Turkish Journal of Pathology, 2014
Oligodendrogliomas are rare in the pediatric population, and most oligodendroglioma-like tumors in this age group may belong to other entities. In addition, accurate diagnosis and grading of such lesions using criteria developed for adult oligodendrogliomas prove difficult, and often controversial.During a study of tumors previously diagnosed as ...

AOSNP‐ADAPTR resource level‐based recommendations on practical diagnostic strategies for ependymomas

Brain Pathology, EarlyView.
Adapting Diagnostic Approaches for Practical Taxonomy in Resource‐Restrained Regions (ADAPTR) recommendations for ependymomas in resource‐restrained settings (RL = resource level; created in BioRender). Abstract Ependymomas are uncommon primary tumors of the central nervous system (CNS) that affect both children and adults.

Accuracy of distinguishing between dysembryoplastic neuroepithelial tumors and other epileptogenic brain neoplasms with [11C]methionine PET [PDF]

Neuro-Oncology, 2014
Dysembryoplastic neuroepithelial tumors (DNTs) represent a prevalent cause of epileptogenic brain tumors, the natural evolution of which is much more benign than that of most gliomas. Previous studies have suggested that [(11)C]methionine positron emission tomography (MET-PET) could help to distinguish DNTs from other epileptogenic brain tumors, and ...
