Administration of Uric Acid in the Emergency Treatment of Acute Ischemic Stroke
Abstract Oxidative stress is one of the main mechanisms implicated in the pathophysiology of inflammatory and neurodegenerative diseases of the central nervous system (CNS). Uric acid (UA) is the end product of purine catabolism in humans, and it is the main endogenous antioxidant in blood. Low circulating UA levels have been associated with an increased prevalence and worse clinical course of several neurodegenerative and inflammatory diseases of the CNS, including Parkinson’s disease and multiple sclerosis. Moreover, the exogenous administration of UA exerts robust neuroprotective properties in experimental m...

Advances in Management of the Stroke Etiology One-Percenters
AbstractPurpose of ReviewUncommon causes of stroke merit specific attention; when clinicians have less common etiologies of stoke in mind, the diagnosis may come more easily. This is key, as optimal management will in many cases differs significantly from “standard” care.Recent FindingsRandomized controlled trials (RCT) on the best medical therapy in the treatment of cervical artery dissection (CeAD) have demonstrated low rates of ischemia with both antiplatelet and vitamin K antagonism. RCT evidence supports the use of anticoagulation with vitamin K antagonism in “high-risk” patients with antiphospholipid antibody...

1. Epileptic seizures in pediatric stroke: Data from the Italian Registry for Childhood Thrombosis
According to data from the Italian Registry for Childhood Thrombosis (R.I.T.I.), in about half cases diagnosis of pediatric stroke occurs after 24h from clinical onset (Baggio et al., SINP2013). The aim of the present study was to evaluate the frequency of seizures at stroke onset and their correlation with time to diagnosis in the pediatric stroke patients in the R.I.T.I. We selected the R.I.T.I. children with first acute arterial (AIS) or venous (CSVT) cerebral infarction occurring between January 2007 and June 2012; we studied prevalence, characteristics and recurrence of epileptic seizures, focusing on diagnostic delay.

Time to Blood Pressure Control Before Thrombolytic Therapy in Patients With Acute Ischemic Stroke: Comparison of Labetalol, Nicardipine, and Hydralazine
Conclusions: Adequate initial dosing of antihypertensive treatment has the potential to reduce time to blood pressure control and possibly time to alteplase therapy. The optimal antihypertensive regimen for controlling blood pressure before alteplase therapy remains unclear.

Intravenous thrombolysis, mechanical embolectomy, and intracranial stenting for hyperacute ischemic stroke in a patient with moyamoya disease
Publication date: Available online 17 February 2016 Source:Journal of Clinical Neuroscience Author(s): Debora S. Argetsinger, Jeffrey W. Miller, Jeffrey J. Fletcher The Japanese translation of moyamoya means “puff of smoke” and refers to the angiographic appearance of dilated collateral vessels seen during chronic progressive narrowing of the intracranial supraclinoid portions of the internal carotid arteries. Despite cerebral ischemia being the most common presenting symptom, 20% to 40% of adults suffer a hemorrhagic stroke. Due to the lack of evidence and histopathologic findings, intravenous and endovascular re...

Where Does the Time Go? The Effect of Protocols for Stroke Last Known Well Documentation on Intravenous Recombinant Tissue Plasminogen Activator Delivery in the Northeast
Conclusions: Improved documentation of LKW times should be attempted. The addition of this variable to existing protocols could more accurately track the number of patients ineligible for treatment based on delayed presentation.

P 165 Incidence, clinical characteristics and longterm course of headache in patients with stroke (DMKG multicenter study)
Post stroke headache is a symptom which is generally not further differentiated. According to previous European and American studies, it is a common phenomenon. Nevertheless, other symptoms of stroke, such as palsy or aphasia, are dominating clinical assessments. However, the symptom “headache” can be an essential part of the clinical picture as in subarachnoid bleeding or cerebral venous thrombosis and it is unclear which risk factors modulate the symptoms and the occurrence of headache in stroke.

DVT Prevention in Stroke
AbstractPurpose of ReviewThe purpose of this review is to discuss the prevention of venous thromboembolism (VTE) in stroke patients. We discuss use of oral anticoagulation and other interventions for the prevention of VTE. A new class of medications, non-vitamin K antagonist oral anticoagulants (NOACs), have been successfully trialed for the prevention of VTE. We review the data and guidance statements for VTE prevention.Recent FindingsWarfarin and vitamin K antagonist drugs have been the mainstay of VTE prevention for decades. More recently, NOACs have become available for both stroke and systemic embolism prevention in n...

Acute treatment of stroke due to spontaneous calcified cerebral emboli causing large vessel occlusion
Conclusions Given the small sample reported in literature and no reported randomised studies, definitive recommendations could not be reached. However, considering thrombus composition, thrombolysis is most probably not sufficient and priority should be given to EVT.

Matrix Metalloproteinase-9 Mediates the Deleterious Effects of α2-Antiplasmin on Blood–Brain Barrier Breakdown and Ischemic Brain Injury in Experimental Stroke
We examined the hypothesis that MMP-9 is an essential downstream mediator of α2-antiplasmin’s deleterious effects during brain ischemia. Middle cerebral artery thromboembolic stroke was induced in a randomized, blinded fashion in mice with increased blood levels of α2-antiplasmin. There was a robust increase in MMP-9 expression (immunofluorescence) in the ischemic vs. the non-ischemic hemisphere of MMP-9+/+ but not MMP-9−/− mice, 24 h after stroke. Brain swelling and hemorrhage were significantly increased in the ischemic vs. the non-ischemic hemisphere of MMP-9+/+ mice. By comparison to MMP-9+/+ mice, the ischem...

Treatment With Intravenous Alteplase for Acute Ischemic Stroke After Reversal of Dabigatran With Idarucizumab: A Case Study
Treatment options for anticoagulated patients presenting with ischemic stroke are limited. Off-label use of idarucizumab to rapidly reverse the anticoagulant effect of dabigatran may ensure eligibility for thrombolytic therapy with alteplase. This case describes a 77-year-old white male who presented to the hospital 89 minutes after sudden onset of right-sided hemiparesis, dysarthria, and facial palsy. Significant history included atrial fibrillation and previous right-sided cortical stroke. Medication reconciliation revealed he was taking dabigatran 150 mg twice a day, with the last dose being 179 minutes before presentat...

Stroke after spontaneous intracranial hypotension: Not a single mechanism. Case report and review of literature
We report a case of SIH followed with brain infarction, with a distinct presentation from previous literature, suggesting a different mechanism. A 35 year-old had severe orthostatic headache, responsible for prolonged bed rest. One month later, he had acute left hemiparesis secondary to stroke and right posterior cerebral artery occlusion. Stroke MRI showed arguments for intracranial hypotension (thickened meninges). He was successfully treated with intravenous rtPA thrombolysis. Headache were resolved after an epidural blood patch. A patent foramen ovale was detected. Clinical features of this description were compared w...

Carotid Web and Ischemic Stroke: A Primer for Nursing
CONCLUSION: With multiple options and the uncertainty of which are best, patients can be lost to follow-up because of confusion and stress. Involving neuroscience nurses in the education process of these patients may help facilitate understanding of this disease phenomenon and increase patient understanding and compliance.
