Related factors with orolingual angioedema after intravenous alteplase in acute ischemic stroke: results from a single-center cohort and meta-analysis.

Introduction: Orolingual angioedema (OA) after intravenous thrombolysis (IVT) with alteplase in acute stroke can be a life-threatening complication. Our aim was to describe its incidence, clinical features, and related factors.

Patients And Methods: We analyzed a single-center cohort of stroke patients treated with IVT in an 8-year period.

Acute Stroke Care during the COVID-19 Pandemic: Reduction in the Number of Admissions of Elderly Patients and Increase in Prehospital Delays.

Introduction: We analyzed whether the coronavirus disease 2019 (COVID-19) crisis affected acute stroke care in our center during the first 2 months of lockdown in Spain.

Methods: This is a single-center, retrospective study. We collected demographic, clinical, and radiological data; time course; and treatment of patients meeting the stroke unit admission criteria from March 14 to May 14, 2020 (COVID-19 period group).

A tool to identify patients with embolic stroke of undetermined source at high recurrence risk.

Objective: A tool to stratify the risk of stroke recurrence in patients with embolic stroke of undetermined source (ESUS) could be useful in research and clinical practice. We aimed to determine whether a score can be developed and externally validated for the identification of patients with ESUS at high risk for stroke recurrence.

Methods: We pooled the data of all consecutive patients with ESUS from 11 prospective stroke registries.

Cerebral amyloid angiopathy-related transient focal neurological episodes: A transient ischemic attack mimic with an increased risk of intracranial hemorrhage.

Background: Transient focal neurological episodes (TFNEs) are a recently recognized clinical presentation of cerebral amyloid angiopathy (CAA). Our aim was to describe the clinical and radiological features of a series of patients with AS.

Methods: We included 11 patients presenting with recurrent transient focal neurological symptoms and radiological features related to CAA.

Renal Function and Risk Stratification of Patients With Embolic Stroke of Undetermined Source.

Background and Purpose- We aimed to assess if renal function can aid in risk stratification for ischemic stroke or transient ischemic attack (TIA) recurrence and death in patients with embolic stroke of undetermined source (ESUS). Methods- We pooled 12 ESUS datasets from Europe and America. Renal function was evaluated using the estimated glomerular filtration rate (eGFR) and analyzed in continuous, binary, and categorical way.

Age- and sex-specific analysis of patients with embolic stroke of undetermined source.

Objective: To investigate whether the correlation of age and sex with the risk of recurrence and death seen in patients with previous ischemic stroke is also evident in patients with embolic stroke of undetermined source (ESUS).

Methods: We pooled datasets of 11 stroke registries from Europe and America. ESUS was defined according to the Cryptogenic Stroke/ESUS International Working Group.

Efficacy of New Measures Saving Time in Acute Stroke Management: A Quantified Analysis.

Background: Time to treatment remains the most important factor in acute ischemic stroke prognosis. We quantified the effect of new interventions reducing in-hospital delays in acute stroke management and assessed its repercussion on door-to-imaging (DTI), imaging-to-needle (ITN), and door-to-needle (DTN) times.

Methods: Prospective registry of consecutive stroke patients who were candidates for reperfusion therapy attended in a tertiary care hospital from February 1 to December 31, 2014.

Risk Stratification for Recurrence and Mortality in Embolic Stroke of Undetermined Source.

Background And Purpose: The risk of stroke recurrence in patients with Embolic Stroke of Undetermined Source (ESUS) is high, and the optimal antithrombotic strategy for secondary prevention is unclear. We investigated whether congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, and stroke or transient ischemic attack (TIA; CHADS2) and CHA2DS2-VASc scores can stratify the long-term risk of ischemic stroke/TIA recurrence and death in ESUS.

Methods: We pooled data sets of 11 stroke registries from Europe and America.

Phenotypic variability in a four generation family with a p.Thr666Met CACNA1A gene mutation.

Background: Familial hemiplegic migraine type 1, episodic ataxia type 2, and spinocerebellar ataxia type 6 are distinct neurological disorders associated with mutations in the CACNA1A gene. Phenotypic variability and clinical overlap are recognized.

Patients: We describe a 2-year-old child with transiently decreased consciousness and clinical and radiological signs of early-onset cerebellar atrophy.

Vascular imaging before intravenous thrombolysis: consequences of in-hospital delay in applying two diagnostic procedures.

Background: Vascular imaging is increasingly used for diagnosis of arterial occlusions in acute ischemic stroke (AIS) patients. Our aim was to determine whether computed tomography angiography (CTA) and Doppler/duplex ultrasound (DUS) before intravenous thrombolysis (IVT) is associated with a delay in time-to-treatment.

Methods: Observational analysis of a prospective cohort of AIS patients treated with IVT from January 2009 to December 2012.
