Modified Rankin scale assessment by telephone using a simple questionnaire.

Purpose: The modified Rankin Scale (mRS) is widely used as a measure of post-stroke physical disability in clinical stroke trials; however, it is affected by inter-rater discrepancies. A Japanese version of the simplified mRS questionnaire (J-RASQ) has the potential to overcome the inter-rater discrepancies and might be feasible for clinical surveys. We aimed to determine the reliability of J-RASQ in a telephone survey administered by non-medical staff.

Alberta Stroke Program Early CT Score Calculation Using the Deep Learning-Based Brain Hemisphere Comparison Algorithm.

Objectives: The Alberta Stroke Program Early Computed Tomography Score (ASPECTS) is a promising tool for the evaluation of stroke expansion to determine suitability for reperfusion therapy. The aim of this study was to validate deep learning-based ASPECTS calculation software that utilizes a three-dimensional fully convolutional network-based brain hemisphere comparison algorithm (3D-BHCA).

Materials And Methods: We retrospectively collected head non-contrast computed tomography (CT) data from 71 patients with acute ischemic stroke and 80 non-stroke patients.

Reliability of the Modified Rankin Scale Assessment Using a Simplified Questionnaire in Japanese.

Objectives: We developed a Japanese version of the simplified modified Rankin Scale questionnaire, of which the agreement between patients or their family members and neurologists was verified in a previous single-center study. In the present study, the reliability of the questionnaire was evaluated in another hospital.

Materials And Methods: The participants were prospectively-registered patients with acute ischemic stroke admitted to Saiseikai Kumamoto Hospital.

Cerebral embolism accompanied by remarkable diffusion-weighted imaging reversal in a 10 month-old infant with congenital heart disease.

•The case of infant ischemic stroke with remarkable DWI reversal.•A mismatch between core volume and visually DWI lesion predicts DWI reversal.•Chronic hypoxia and early recanalization may contribute to large DWI reversal.

Tissue Plasminogen Activator for Cortical Embolism Stroke with Magnetic Resonance Perfusion Imaging: A Report of Two Cases.

Computerized tomography (CT) or magnetic resonance imaging (MRI) is indispensable for diagnosing acute ischemic stroke (AIS) patients who are candidates for recombinant tissue plasminogen activator (rt-PA) therapies, but further investigation concerning appropriate selection of therapy following advanced imaging including perfusion imaging has not yet been done. The 2018 AHA guidelines have recommended not to perform excessive time-consuming imaging before rt-PA. Here we describe two cases in which reperfusion therapy was decided based on advanced imaging.

[Reliability of modified Rankin Scale assessment with a Japanese version of simplified modified Rankin Scale Questionnaire (J-RASQ)].

Modified Rankin Scale (mRS) is widely used as an indicator of physical disability after the onset of stroke and a main evaluation scale in clinical stroke trials but sometimes has discrepancies among raters. We designed a Japanese version of simplified mRS questionnaire (J-RASQ) to evaluate mRS using closed question to assess the difference from the original. Currently there are no Japanese version of mRS questionnaire and its validity and reliability assessment has been warranted.

Detection of Stenosis Progression in Intracranial Vertebral Artery Dissection Using Carotid Ultrasonography.

Background: The purpose of this study was to assess whether carotid ultrasonography indices detect arterial stenosis progression in patients with vertebral artery (VA) dissection.

Methods: This was a retrospective, single-center, observational study that enrolled patients with intracranial VA dissection who were admitted from January 2011 to June 2017. Magnetic resonance angiography (MRA) was done on admission and followed up at a median 20 days after onset (interquartile range [IQR] 9-58 days), and ultrasonography was performed at a median of 22 (interquartile range 7-56) days.

Clinical and Radiological Characteristics of Intracranial Artery Dissection Using Recently Proposed Diagnostic Criteria.

Background: Data on the clinical and radiological characteristics of intracranial artery dissection (IAD) have remained limited. Our purpose was to reveal the clinical and radiological characteristics of IAD according to diagnostic criteria for IAD as recently reported by a group of international experts.

Methods: Patients were retrospectively enrolled using a prospective single-center stroke registry between 2011 and 2016.
