Article
Background and aim Atrial fibrillation is associated with increased risk of ischemic stroke and its global prevalence is increasing. We aimed to describe the contemporary temporal trends in hospital admissions, case fatality rate, as well as sex differences in atrial fibrillation-related stroke in Canada. Methods We conducted a retrospective cohor...
Article
The mechanisms for neurological complications of COVID-19, the disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), are not yet well understood. We present a critically ill man with a COVID-19-associated hemorrhagic encephalopathy. SARS-CoV-2 RNA was not detected in cerebrospinal fluid (CSF) or blood. CSF analyses suggest...

We report the recruitment activities and outcomes of a multi-disease neuromuscular patient registry in Canada. The Canadian Neuromuscular Disease Registry (CNDR) registers individuals across Canada with a confirmed diagnosis of a neuromuscular disease. Diagnosis and contact information are collected across all diseases and detailed prospective data...
Article
Introduction/aims: Consensus criteria to formalize the diagnosis of amyotrophic lateral sclerosis (ALS) and refine clinical trial populations have evolved. The recently proposed Gold Coast consensus criteria are intended to simplify use and increase sensitivity. We aimed to evaluate the potential impact of those criteria on clinical trial eligibil...
Article
Full-text available
Background: There are uncertainties regarding the optimal management of acutely symptomatic carotid stenosis (“hot carotids”). We sought to explore the approaches of stroke physicians to anti-thrombotic management, imaging, and revascularization in patients with “hot carotids”. Methods: We used a qualitative descriptive methodology to examine decis...
Article
Full-text available
Background Evidence informing the choice between carotid endarterectomy and carotid artery stenting for acutely symptomatic carotid stenosis (“hot carotid”) is dated and does not factor in contemporary therapies or techniques. The optimal imaging modality is also uncertain. We explored the attitudes of stroke physicians regarding imaging and revasc...
Article
Full-text available
Background: Patients with acutely symptomatic carotid stenosis (“hot carotid”) have high up-front risk of recurrent strokes. Uncertainties remain regarding optimal anti-thrombotic management, particularly while awaiting revascularization with endarterectomy or stenting (CEA/CAS). Methods: We administered a worldwide electronic survey through Neurol...
Article
Full-text available
Background: Whereas the beneficial effect of antiplatelet therapy for recurrent stroke prevention is well-established, uncertainties remain regarding the optimal anti-thrombotic regimen for acutely symptomatic carotid stenosis (“hot carotid”), particularly as patients await revascularization. We sought to explore the approaches of stroke physicians...

Background: Evidence informing the choice between endarterectomy and stenting for acutely symptomatic carotid stenosis (“hot carotid”) is dated, and uncertainties remain regarding the optimal imaging modality. We sought to explore the thoughts of stroke physicians regarding the perioperative management of patients with acute symptomatic carotid ste...
Article
Background: Balloon guide catheters are increasingly used to improve clot retrieval by temporarily stopping proximal blood flow during endovascular thrombectomy. Purpose: Our aim was to provide a summary of the literature comparing the procedural and clinical outcomes of endovascular thrombectomy with or without balloon guide catheters, dependin...
Article
Untreated herpes simplex virus type 1 (HSV-1) encephalitis is associated with high mortality. Missed cases can have devastating consequences. Detection of HSV-1 in cerebrospinal fluid (CSF) with polymerase chain reaction (PCR) is reported to have high sensitivity and specificity and is considered the diagnostic gold standard for HSV-1 encephalitis....

Objective: To examine practice variations in anti-thrombotic management of patients with “hot carotids” awaiting carotid endarterectomy(CEA) or angioplasty/stenting(CAS) Background: Patients with acutely symptomatic carotid stenosis(“hot carotid”) have high up-front risk of recurrent strokes. Uncertainties remain regarding optimal anti-thrombotic...
Conference Paper
Introduction Randomized trials of direct aspiration (ADAPT) vs retrievable stent (RS) did not show a difference in 90-day outcomes. We searched existing literature for differences in reperfusion times and success between the two techniques. Methods We performed a systematic review to identify relevant articles in electronic databases and referen...

Article
Background: Despite the potential for faster postoperative recovery and the ease of direct intraoperative injection, intrathecal morphine is rarely provided in lumbar spine surgery. Objective: To evaluate the safety and efficacy of intrathecal morphine following lumbar fusion. Methods: We randomly assigned 150 patients undergoing elective inst...
Presentation
Background: Atrial fibrillation (AF) is associated with increased risk of ischemic stroke. In Canada, the contemporary burden of AF-related stroke is incompletely characterized. Our objective was to determine temporal trends in hospital admissions and in-hospital mortality for AF-related stroke in Canada from 2007 to 2015. Methods: We conducted a r...
Poster
Background: Unplanned hospital readmission is inconvenient for patients, puts them at risk of harm, and is a resource strain. We reviewed available literature on risk factors for readmission following discharge specifically from neurology inpatient services with a focus on factors unique to non-stroke neurology admissions. Methods: We conducted a s...

Case Description: A 64 year-old male presented with left-sided weakness and altered level of consciousness after a suspected seizure. MR Brain demonstrated right mesial temporal lobe diffusion restriction. Empiric antiviral and antibiotic treatments were initiated despite CSF negative for HSV/VZV and enteroviruses. Lumbar puncture on admission day...
Article
Background: Atrial fibrillation (AF) is an important risk factor for ischemic stroke but has no recognized screening method. Wearable devices have the potential to provide near continuous monitoring to detect AF. This systematic review evaluates the current state of software capable of detecting AF using wearable devices. Methods: We conducted a sy...

Objectives: Intrathecal morphine (ITM) is an efficacious method of providing postoperative analgesia and reducing pain associated complications. Despite adoption in many surgical fields, ITM has yet to become a standard of care in lumbar spine surgery. Spine surgeons' reticence to make use of the technique may in part be attributed to concerns of...
Article
Despite the ease of intraoperative injection, intrathecal morphine (ITM) is rarely provided in lumbar spine surgery. We therefore sought to demonstrate the safety and efficacy of ITM following lumbar fusion. Methods: In this double-blind trial, 150 patients undergoing elective instrumented lumbar fusion were randomly assigned to receive a single in...
Article
Intrathecal morphine (ITM) is an efficacious method of providing post-operative analgesia. Despite adoption in many surgical fields, ITM has yet to become a standard of care in lumbar spine surgery. This may in part be attributed to concerns over precipitating a cerebrospinal fluid (CSF) leak following dural puncture. Methods: The dural sac is pene...
Article
Several studies have demonstrated that obese patients are at increased risk of perioperative complication during lumbar spine surgery. Herein we quantify the association between blood loss and obesity during lumbar fusion. Methods: Outcomes were collected in the setting of a single center randomized control trial conducted among patients undergoing...
