Development and Validation of a Novel Human-Fixed Cadaveric Model Reproducing Cerebrospinal Fluid Circulation for Simulation of Endoscopic Endonasal Skull Base Surgery.

Background And Objectives: Endoscopic endonasal surgery is a well-established surgical approach to the skull base. Surgeons need a reusable long-lasting tool to acquire the skills needed for skull base reconstruction. The aim of this study was to elaborate and validate a human formalin-fixed cadaveric model that reproduces a realistic cerebrospinal fluid (CSF) circulation and that adequately renders a CSF leak.

Metastatic Seeding From a Gastrointestinal Neoplasia in a Pituitary Adenoma: A Case Report and Literature Review.

Pituitary composite tumors consisting of metastasis within an adenoma are rare and aggressive entities. We present a case of esophageal adenocarcinoma metastasis at a prolactinoma presenting in a unique fashion and highlight how this case could contribute to a better understanding and early recognition of this condition. The patient was a 65-year-old male who presented with partial palsy of the third and sixth cranial nerves.

A Canadian National Survey of the Neurosurgical Management of Intracranial Abscesses.

Objective: Intracerebral abscess is a life-threatening condition for which there are no current, widely accepted neurosurgical management guidelines. The purpose of this study was to investigate Canadian practice patterns for the medical and surgical management of primary, recurrent, and multiple intracerebral abscesses.

Methods: A self-administered, cross-sectional, electronic survey was distributed to active staff and resident members of the Canadian Neurosurgical Society and Canadian Neurosurgery Research Collaborative.

Spontaneous spinal epidural hematoma related to amphetamine abuse: A case report.

Background: Spontaneous spinal epidural hematoma (SSEH) is a rare condition that is typically associated with hypertension, the use of antithrombotic or sympathomimetic drugs. Here, we report a case of SSEH attributed to the use of amphetamines.

Case Description: A 27-year-old amphetamine user presented with the sudden onset of paraplegia (Frankel A) following amphetamine use.

Adapting the Canadian CT head rule age criteria for mild traumatic brain injury.

Objective: With the ageing population, the prevalence of mild traumatic brain injury (mTBI) among older patients is increasing, and the age criteria of the Canadian CT head rule (CCHR) is challenged by many emergency physicians. We modified the age criteria of the CCHR to evaluate its predictive capacity.

Methods: We conducted a retrospective cohort study at a level 1 trauma centre ED of all mTBI patients 65 years old and over with an mTBI between 2010 and 2014.

Selective Prereduction Radiography in Anterior Shoulder Dislocation: The Fresno-Quebec Rule.

Background: Shoulder dislocation is one of the most frequent dislocations encountered by emergency physicians. Typical emergency care usually includes performing both prereduction and postreduction radiography. However, selective radiography has the potential benefits of reducing emergency department (ED) time and radiation exposure.
