New CNS tumor classification: The importance in pediatric neurosurgical practice.

Background: The management of the central nervous system (CNS) tumors in the pediatric population is crucial in neurosurgical practice. The World Health Organization (WHO) has evolved its classification of CNS tumors from the 19 century to the 5 edition, published in 2021, incorporating molecular advancements. This transition from morphology to molecular characterization is ongoing.

Pediatric hemispheric cerebellar low-grade gliomas: clinical approach, diagnosis, and management challenges-experience at a tertiary care children's hospital.

Purpose: This study aims to provide an exhaustive analysis of pediatric low-grade gliomas (pLGGs) in the cerebellar hemispheres, focusing on incidence, clinical characteristics, surgical outcomes, and prognosis. It seeks to enhance understanding and management of pLGGs in the pediatric population.

Methods: We conducted an observational, descriptive, retrospective, and cross-sectional study at a pediatric hospital, reviewing medical records of 30 patients with cerebellar hemispheric pLGGs treated from December 2014 to January 2023.

Tumors of the central nervous system. Classification of the World Health Organization 2021. Towards a paradigm shift.

The study of central nervous system (CNS) tumors is a subject of great interest and such knowledge is of great importance in medical practice. The classifications of CNS neoplasms began in the mid-19th century, until the World Health Organization (WHO) published, in 1979, the first edition of a useful systematic review for the purpose of establishing a common language for all medical specialties. To date, 5 updated editions of neoplastic taxonomy have been published.

Inflammatory myofibroblastic tumor of the lung involving the central nervous system in pediatric patients.

Introduction: The inflammatory myofibroblastic tumor (IMT) is a very rare lesion with an incidence of less than 0.1% of total neoplasms and with main affection in the lungs. Involvement in the central nervous system is extremely rare, but with a much more aggressive course than IMT diagnosed in the rest of the body.

Abusive head trauma, protocols, and legal concerns in a South American Country.

The abusive head trauma (AHT) is a form of child abuse and is a frequent entity all over de world. It is particularly unique among medical diagnoses because of the legal implications imposed by the diagnosis. Therefore, it has been the subject of much legal controversy over the decades.

Method to perform safety stereotactic procedures in children under 2 years of age.

Introduction: Stereotactic procedures have been used in neurosurgery for many years. In children especially, care should be considered to avoid complication caused by fixation of the frame in a not fully developed skull bone. We present our method to adapt the frame in children under 2 years of age.

[Paradoxical reaction during tuberculosis treatment in immunocompetent children: case report].

Tuberculosis is an important public health problem. It is estimated that around 5-10% of patients with tuberculosis present with central nervous system involvement; meningitis and tuberculoma being two of the most frequent manifestations. The paradoxical reaction in patients undergoing antituberculosis treatment is infrequent, nevertheless it is an important consideration in patients, who after an appropriate initial response to specific treatment, present with worsening clinical and radiological signs or the appearance of new lesions.
