Objective: Determine the histopathological and clinical characteristics of patients diagnosed with meningiomas and to establish the frequency of these tumors in the pediatric population Mexican. Determine the NF1/2 frequency in meningioma pediatric.
Methods: Samples from the histopathology file were reviewed, and from the complete clinical file the following patient data was reviewed: age, gender, diagnosis, diagnosis year, surgical resection, location, tumor size, symptoms, and family background. The frequency of NF1/2 in pediatric meningioma was reviewed in literature.
Results: Forty-four de novo cases were collected from pediatric patients; 19 were female patients and 25 males. The most frequent histological subtype was transitional meningioma. Of all the cases, 75% had a supratentorial localization and 20% had an extramedullary intrarachidian localization. Some clinical manifestations included seizures, paresis, headache, and visual disturbances.
Conclusion: There is a low incidence of meningiomas in the pediatric population, more than 70% are Grade I, and they have supratentorial localization.

Introduction: Meningiomas are the most common primary central nervous system tumors, often requiring surgical resection. Presurgical embolization (PSE) is used to reduce intraoperative bleeding, although its effectiveness varies. This study evaluates the safety and efficacy of PSE using ethyl-vinyl alcohol (EVOH) in meningioma surgeries.

Purpose: It is not known whether temporal changes in childhood cancer therapy have reduced risk of subsequent malignant neoplasms (SMNs) of the central nervous system (CNS), a frequently fatal late effect of cancer therapy.
Methods: Five-year survivors of primary childhood cancers diagnosed between 1970-1999 in the Childhood Cancer Survivor Study with a subsequent CNS SMN were identified. Cumulative incidence rates and standardized incidence ratios (SIR) were compared among survivors diagnosed between 1970-1979 (N = 6223), 1980-1989 (N = 9680), and 1990-1999 (N = 8999).
Overall survival and progression-free survival in pediatric meningiomas: a systematic review and individual patient-level meta-analysis.

Background: Pediatric meningiomas (PMs) are rare central nervous system tumors, accounting for 1-5% of all meningiomas, and differ from adult meningiomas in clinical, histopathological, and molecular features. Current guidelines primarily focus on adults, leaving a gap in evidence-based management for PMs. This study presents the largest meta-analysis of longitudinal individual patient data (IPD) to date, addressing progression-free survival (PFS) and overall survival (OS) in pediatric patients.

Background And Objectives: The middle fossa approaches are tremendously versatile for treating small vestibular schwannomas, selected petroclival meningiomas, midbasilar trunk aneurysms, and lesions of the petrous bone. Our aim was to localize the internal acoustic canal and safely drill the petrous apex with these approaches. This study demonstrates a new method to locate the internal acoustic canal during surgery in the middle fossa.

Resveratrol, a naturally occurring polyphenolic compound found in various plants, has been extensively studied for its broad spectrum of beneficial biological effects. These encompass its potent antioxidant properties, anti-inflammatory activities, anti-aging capabilities, cardioprotective functions, and neuroprotective potential. The diverse biological actions of resveratrol extend beyond these well-established properties.
