A new hernia blocking system to prevent recurrent lumbar disc herniation: surgical technique, intraoperative findings and six-months post-operative outcomes.

Purpose: The aim of this study was to evaluate the performance and safety of a new hernia blocking system (HBS), implanted after a limited discectomy, to prevent recurrence of lumbar disc herniation.

Methods: Prospective, multicenter (6 sites), cohort clinical investigation. Thirty patients with a postero-lateral disc herniation between L4-S1 and large annular defects (> 6 mm wide), who underwent a limited discectomy and were treated with a new HBS (DISC care, NEOS Surgery S.

Dural Venous Sinus Variations in Idiopathic Subarachnoid Hemorrhage: A New Indicator of the Venous Origin with Diagnostic Usefulness?

Objective: Venous hypertension associated with a primitive basal vein of Rosenthal (BVR) has been noted as the most likely cause of idiopathic subarachnoid hemorrhage (iSAH). Other types of venous drainage variations have been scarcely studied but may further explain the cases not associated with a BVR anomaly. Our aim was to investigate if dural venous sinus (DVS) anomalies are related with iSAH.

Mobile cauda equina ependymoma, case report and literature review.

The aim of this study was to describe a very rare presentation of ependymoma that can derive from intraoperative complications for surgeons and increased morbidity for the patients. Multiple cases of mobile cauda equina tumors leading to inadequate approach have been reported in the literature, however, the reports of ependymoma histology are very rare. This report describes the third adult case in recent years and a retrospective review of cases reported in the literature until today.

Women's role in neurosurgical research: is the gender gap improving?

Objective: The percentage of women publishing high-impact neurosurgical research might be perceived as a representation of our specialty and may influence the perpetuation of the existing gender gap. This study investigated whether the trend in women taking lead roles in neurosurgical research has mirrored the increase in female neurosurgeons during the past decade and whether our most prestigious publications portray enough female role models to stimulate gender diversity among the new generation of neurosurgeons.

Methods: Two of the most prominent neurosurgical journals-Journal of Neurosurgery and Neurosurgery-were selected for this study, and every original article that was published in 2009 and 2019 in each of those journals was investigated according to the gender of the first and senior authors, their academic titles, their affiliations, and their institutions' region.

Validation of shunt dependency prediction scores after aneurysmal spontaneous subarachnoid hemorrhage.

Background: Currently available scores for predicting shunt dependency after aneurysmal spontaneous subarachnoid hemorrhage (aSAH) are limited and not widely accepted. The key purpose of this study was to validate a recently created score for shunt dependency in aSAH (SDASH) in an independent population of aSAH patients. We compared this new SDASH score based on a combination of the Hunt and Hess grade, Barrow Neurological Institute (BNI) score, and the presence or not of acute hydrocephalus with other published predictive scores.

Iatrogenic Intracranial Aneurysm After External Ventricular Drain Placement: Traumatic or Mycotic Origin? Case Report and Literature Review.

Background: Intracranial iatrogenic aneurysms (IIAs) developing after external ventricular drain (EVD) placement or removal have been only rarely reported. Most of these reports assumed a traumatic etiology; however, some have demonstrated an inflammatory origin. We have presented the case of an IIA that developed after an EVD had been inserted to treat acute hydrocephalus secondary to a ruptured arteriovenous malformation.

Amateur Endurance Athletes: At Higher Risk of Suffering Dural Arteriovenous Fistulas? Report of 3 Cases.

Background: The present study aims to draw attention to the fact that endurance sport could be a risk factor for dural arteriovenous fistula (DAVF) development. DAVFs have been correlated with acquired dural venous sinus anomalies owing to trauma, infection, neoplasia, or other classic risk thrombogenic factors. Here we report 3 cases of intracranial DAVF in young healthy patients who had no known thrombogenic risk factors other than amateur intensive sports practice.

Growth prediction in asymptomatic meningiomas: the utility of the AIMSS score.

Background: Management of asymptomatic meningiomas represents a challenge due to the absence of a solid consensus on which is the best management strategy. There are various known factors predicting meningiomas growth risk. However, the Asian Intracranial Meningioma Scoring System (AIMSS) is the only described score to quantify such risk thus emerging as a potential tool for management decisions.

Anxiety, hospital fears and conduct and behavioral alterations during pediatric hospitalization.

Introduction: A hospital admission is an experience capable of generating emotional and behavioral alterations at any age. This study pretends to analyze the response of anxiety, fears and/or behavioral alterations in pediatric patients exposed to a conventional non-surgical hospital admission and the existing relationship between these responses and certain modulating variables. Metodology.

Comparison of elevated intracranial pressure pulse amplitude and disproportionately enlarged subarachnoid space (DESH) for prediction of surgical results in suspected idiopathic normal pressure hydrocephalus.

Background: To compare the prognostic value of pulse amplitude on intracranial pressure (ICP) monitoring and disproportionately enlarged subarachnoid space hydrocephalus (DESH) on magnetic resonance imaging (MRI) for predicting surgical benefit after shunt placement in idiopathic normal pressure hydrocephalus (iNPH).

Method: Patients with suspected iNPH were prospectively recruited from a single centre. All patients received preoperative MRI and ICP monitoring.

Safety and Efficacy of 5-Aminolevulinic Acid for High Grade Glioma in Usual Clinical Practice: A Prospective Cohort Study.

Background: During the last decade, the use of 5-aminolevulinic acid (5-ALA) has been steadily increasing in neurosurgery. The study's main objectives were to prospectively evaluate the effectiveness and safety of 5-ALA when used in clinical practice setting on high-grade gliomas' patients.

Methods: National, multicenter and prospective observational study.
