Long-term epidemiological trends in (primary) pediatric central nervous system tumors: a 25-year cohort analysis in Western Mexico.

Background: Central nervous system tumors (CNSTs) represent a significant oncological challenge in pediatric populations, particularly in developing regions where access to diagnostic and therapeutic resources is limited.

Methods: This research investigates the epidemiology, histological classifications, and survival outcomes of CNST in a cohort of pediatric patients aged 0 to 19 years within a 25-year retrospective study at the Civil Hospital of Guadalajara, Mexico, from 1999 to 2024.

Results: Data was analyzed from 273 patients who met inclusion criteria, revealing a higher incidence in males (51.

Frontal aslant tract: Anatomy and tractography description in the Mexican population.

Background: The aim of the study was to describe the origin, course, and termination of frontal aslant tract (FAT) in the Mexican population of neurosurgical referral centers.

Methods: From January 2018 to May 2019, we analyzed 50 magnetic resonance imaging (MRI) studies in diffusion tensor imaging sequences of patients of the National Institute of Neurology and Neurosurgery "Manuel Velasco Suárez." Five brains were fixed by the Klingler method and dissected in the neurosurgery laboratory of the Hospital Civil de Guadalajara to identify the origin, trajectory, and ending of the FAT.

Awake Surgery With Visual Pathway Mapping in Low Grade Glioma Surgery.

The visual pathway and its defects have been thoroughly studied in clinical correlation to temporal lobe lesions related to epilepsy and traumatic lesions. Nevertheless, its clinical correlation and other decision-making have not been addressed regarding neoplastic lesions. We present a case report of a 28-year-old man with a one-year history of generalized seizures and left superior homonymous quadrantanopia, with no other neurological disturbance on physical examination.

Analysis of Intraoperative Seizures During Bipolar Brain Mapping in Eloquent Areas: Intraoperative Seizures in brain mapping.

Objectives: Awake Craniotomy (AC) is a very well described technique that is performed to make an adequate tumor resection preserving the functionality of the patient. Intraoperative Seizures (IS) are reported as a failure of such procedure. We analyze the incidence and risk factor during AC.

Response to SARS-CoV-2 Pandemic in a Non-COVID-19 Designated Latin-American Neurosurgery Department.

Background: Mexico declared the first case of novel coronavirus disease (COVID-19) in February 2020. At the time we write this article, our country is facing a community spread phase, expecting a rapid increase in the number of cases and fatalities. The Fray Antonio Alcalde Civil Hospital of Guadalajara has been declared a non-COVID-19 hospital with the mission of providing care to patients already registered and also those transferred from neurosurgical departments of neighboring centers, which have been converted into COVID-19 only hospitals.

Awake surgery with cortical-subcortical mapping in diffuse gliomas adjacent to central lobe. Report of two cases and literature review.

Introduction: Diffuse gliomas are brain neoplasms with an infiltrative growing pattern to cortical and subcortical structures, frequently adjacent to eloquent areas; direct cortical and subcortical stimulation in awake craniotomy is a useful tool to achieve a gross total resection with the least neurological deficit.

Presentation Of Cases: A 24 years old male presented with tonic-clonic seizures. The magnetic resonance imaging (MRI) showed a left parietal glioma.

Evaluation of blood pressure measurements in first ambulatory neurological consultations: a missed part of the physical examination?

Objective: To obtain a blood pressure reading is mandatory during either the general or specialized physical examination. This study describes factors associated with the accomplishment of blood pressure measurement in the first neurological consultation.

Methods: We studied first ambulatory neurology consultations in a Mexican referral hospital.
