Backgrounds: Different surgical approaches have been used to remove anterior skull base meningiomas (ASBMs) such as olfactory groove (OG) and tuberculum sellae (TS) meningiomas. These tumors are traditionally resected through pterional (PT), lateral supraorbital (LS) approaches. The endonasal endoscopic (EE) approach has gained some attention in re...

Introduction: Olfactory Groove Meningiomas (OGMs) are treated by Microsurgical Transcranial Approaches (MTCAs) composed of Anterior Sub-frontal Approaches (ASFAs), Lateral Sub-frontal Approaches (LSFAs) and Superior-Interhemispheric Approach (SIHA); Minimally-Invasive (MITCAs) and Endoscopic-Endonasal Approaches (EEAs). Research Question: Determin...

Introduction Meritocracy, a concept revered as the cornerstone of fairness and equal opportunity, is critically examined in the context of neurosurgery. This article challenges the notion that success in this demanding field is solely determined by individual abilities and effort. It reveals that factors such as background, gender, and socioeconomi...

Purpose DSFC (delayed subaponeurotic fluid collection) is a benign pathology associated with the first weeks of life and scarcely described in the literature. Normally characterized by a lack of trauma and/or cranial fracture, it is associated with a history of instrumental delivery and the use of fetal electrodes. Taking it in consideration in the...

Background Diagnosis of idiopathic normal pressure hydrocephalus (iNPH) is based on clinical, radiological, and hydrodynamic data of cerebrospinal fluid (CSF) obtained by invasive methods such as lumbar infusion test, which is used to determine the resistance to CSF outflow (Rout). However, Rout has limitations, and its value as predictor of valve...

We report two rare and infrequent cases, one of a patient with a Cognard type V tentorial dural fistula diagnosed at the beginning as a trunk glioma in a patient with gait disturbance. And another with a Guillian Barré syndrome with tetraparesis secondary to a tentorial dural arteriovenous fistula.

Objectives The large number of infected patients requiring mechanical ventilation has led to the postponement of scheduled neurosurgical procedures during the first wave of the COVID-19 pandemic. The aims of this study were to investigate the factors that influence the decision to postpone scheduled neurosurgical procedures and to evaluate the effe...

This work is aimed at analyzing the neurocognitive functioning (NF) and the quality of life (QoL) of adult subjects with meningioma treated with primary and / or adjuvant radiotherapy. The following databases were searched: Academic Search Complete, CINAHL, Medline, Psychology Database, PsycInfo, PubMed, Scopus and Web of Science, from January 2020...

Objective To assess the effect of the first wave of the SARS-CoV-2 pandemic on the outcome of neurosurgical patients in Spain. Settings The initial flood of COVID-19 patients overwhelmed an unprepared healthcare system. Different measures were taken to deal with this overburden. The effect of these measures on neurosurgical patients, as well as th...

Background and objective: To study the prognostic value of the resistance to the cerebrospinal fluid outflow (Rout) obtained in the lumbar infusion test in idiopathic normal pressure hydrocephalus (iNPH), as well as the pulse pressure amplitudes in the different periods of the test and other new variables extracted by Neuropicture® software. Mate...

Resumen Antecedentes y objetivo Estudiar la validez pronóstica de la resistencia a la salida de líquido cefalorraquídeo (Rout) obtenida en el test de infusión lumbar en el estudio de la hidrocefalia idiopática de presión normal (iNPH), al igual que de las amplitudes en los diferentes tramos del test y otras nuevas variables obtenidas con el softwa...

Background The distribution and role of tumor infiltrating leucocytes in glioblastoma (GBM) remain largely unknown. Here, we investigated the cellular composition of 55 primary (adult) GBM samples by flowcytometry and correlated the tumor immune profile with patient features at diagnosis and outcome. Methods GBM single‐cell suspensions were staine...
