A Multicenter Diagnostic Accuracy Study on Prehospital Stroke Screening Scales

CONCLUSION: Based on the findings of the present study, highly sensitive tests that can be used in this regard are Cincinnati Prehospital Stroke Scale (CPSS), Face-Arm-Speech-Time (FAST), and Med PACS, all of which have about 95% sensitivity. On the other hand, none of the studied tools were desirable (specificity above 95%) in any of the examined cut-offs.PMID:34488307 | DOI:10.34172/aim.2021.65

Online ahead of print.ABSTRACTBACKGROUND: Leukoaraiosis is a type of lesion characterized by tissue rarefaction or myelin pallor resulting from axons loss and gliosis. Synthetic magnetic resonance imaging (MRI) could yield quantitative T1, T2, proton density (PD) values of leukoaraiosis in addition to information on the volume of the lesion.PURPOSE: To investigate the feasibility of quantifying leukoaraiosis using synthetic MRI and to explore the association between leukoaraiosis and cerebral small vascular diseases and cerebral atherosclerosis.MATER...

We present the story of a 6-month-old Old Order Amish infant with underlying Williams syndrome, a rare neurodevelopmental disorder caused by a microdeletion, encompassing the elastin gene that produces abnormalities in elastic fibers of the lungs and vessels. This infant presented with lethargy, irritability, and a new-onset generalized tonic-clonic seizure. Brain magnetic resonance imaging (MRI) was consistent with ischemic stroke in the supratentorial regions. MR angiogram demonstrated bilateral narrowing of the internal carotid arteries with “ivy sign,” suggestive of Moyamoya. Moyamoya disease/syndrome is a ...

This study aimed to fill this gap and systematically investigate its clinical significance. In this retrospective cohort study, we screened all adult patients with MMD hospitalized from January 2016 to January 2020 and collected their baseline clinical and imaging information. Univariate and multivariate logistic regression analyses were then performed to determine which imaging markers were independently associated with MMD characteristics, including cerebrovascular morphology, cerebral hemodynamics, cerebrovascular events, and postoperative collateral formation (PCF). A total of 312 cerebral hemispheres images were colle...

Conclusion: Image of patients with gastrointestinal malignant tumor-related AIS is characterized by three territory sign (multiple lesions in different vascular supply areas). Increased TAT and D-dimer levels are independent prognostic risk factors. TAT is more sensitive to predict prognosis than D-dimer.

CONCLUSIONS: DBT positively influences memory function after PEA. This effect is most likely caused by the reduction of gaseous microemboli.TRIAL REGISTRATION: This study is registered in the German Clinical Trials Register, ID: DRKS00021499.PMID:34795929 | PMC:PMC8575830 | DOI:10.21037/jtd-21-831

AbstractMitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) is a disease that should be considered as a differential diagnosis to acute ischemic stroke taking into account its onset pattern and neurological symptoms, which are similar to those of an ischemic stroke. Technological advancements in neuroimaging modalities have greatly facilitated differential diagnosis between stroke and MELAS on diagnostic imaging. Stroke-like episodes in  MELAS have the following features: (1) symptoms are neurolocalized according to lesion site; (2) epileptic seizures are often present; (3) lesio...

Transcranial Doppler ultrasonography (TCD) can detect microembolic signals (MESs) that are one of the pathogenic indications of ischemic stroke. However, MESs are not uncommon findings during carotid endarterectomy (CEA). The aim of this study was to evaluate the association between MESs and postoperative neurologic events (transient ischemic attack [TIA] or stroke) or new brain lesions (NBLs) on magnetic resonance imaging (MRI).

This report examines the etiology of hemiballistic movements that began 24 hours after a 63-year-old male with vascular risk factors received tissue plasminogen activator (tPa) and thrombolysis in cerebral ischemia 3 (TICI3) thrombectomy for a left middle cerebral artery (MCA) ischemic stroke. The clinical course was reviewed from an admission at a large academic institution where assessments included physical exams, head and neck computed tomography angiography (CTA), and head magnetic resonance imaging (MRI) without contrast. The patient's initial physical exam was consistent with a left MCA syndrome and included a Natio...
