OBJECTIVE: Adverse neurologic outcomes, like stroke, in intensive care unit (ICU) patients after cardiac surgery can have devastating consequences, among them increased mortality risk and, among survivors, loss of independence and a diminished quality of life. Non-contrast computed tomography (CT) remains a widely utilised modality for assessing stroke; however, it ...

Several studies suggest that patients with giant cell arteritis (GCA) presenting with isolated polymyalgia rheumatica (PMR) with no cranial symptoms are at low risk of suffering GCA-related ischemic events. However, the issue remains controversial. In the current study we assessed the development of ischemic events in a large series of ...

OBJECTIVE: Gliomas are among the highest vascularized tumors. We hypothesized that patients with gliomas have increased levels of circulating endothelial progenitor cells (EPCs) and circulating endothelial nitric oxide synthase (eNOS). METHODS: The fraction of EPCs was quantified by fluorescence-activated cell sorter analysis using anti-CD34, -CD133 and -KDR (kinase insert domain ...

Inflammation is receiving increased attention as a cause of atherosclerosis and stroke. Several inflammatory biomarkers, and particularly high-sensitivity C-reactive protein (hsCRP), have been identified as likely predictors of the risk of a future stroke. In clinical settings, it has been consistently observed that higher concentrations of CRP are associated with ...

The perfusion-diffusion mismatch (PDM) model has been proposed as a tool to select acute stroke patients who are most likely to benefit from reperfusion therapy. The clinical-diffusion mismatch (CDM) model is an alternative method that is technically less challenging because it does not require perfusion-weighted imaging. This study is an ...

Acute stroke patients with large artery occlusive disease (LAOD) have a distinct pathophysiology and may respond differently to anticoagulation treatments. We compared the efficacy of a low-molecular-weight heparin (LMWH), nadroparin calcium, with aspirin in Asian acute stroke patients with LAOD. Acute ischaemic stroke patients with onset of symptoms less than ...

OBJECTIVES: About one in five patients with atrial fibrillation have significant carotid artery disease, but not all strokes are cardioembolic in origin in these patients. PURPOSE: We investigated stroke sub-types based mainly on clinical, carotid ultrasonographic, and neuroimaging findings in ischemic stroke patients with non-valvular atrial fibrillation (NVAF). PATIENTS AND ...

Following stroke an equinus deformity of the foot may develop, which may affect the gait pattern of patients differently. Sub-categorization of gait patterns in these patients would be helpful in developing and delivering more targeted treatment. A hierarchical cluster analysis was used to classify the gait patterns of 23 chronic ...

Acute multiple infarcts in multiple cerebral circulations (AMIMC) are thought to suggest the presence of cardioembolic sources or systemic hypercoagulopathy. However, the mechanism and the simultaneous occurrence of AMIMC are not well known. We reviewed 685 consecutive acute ischemic stroke patients who underwent diffusion-weighted imaging (DWI) within 48 hours of ...

This short communication presents significantly increased permeability in two patients with acute stroke, indicating an early blood-brain barrier disruption. Neither of the patients had undergone any thrombolytic therapy and hemorrhaged later. Increased permeability was assessed in both patients using a distributed-parameter model of capillary-tissue exchange. Our findings indicate that early ...

BACKGROUND AND PURPOSE: Arterial thromboembolism is a common cause of both visceral and brain infarctions. Because the cause of brain infarction is unknown in up to 39% of patients, the discovery of subdiaphragmatic visceral infarction (SDVI) in this context is important, but its frequency is unknown. We therefore investigated the ...

OBJECTIVES: Instead of the mismatch in MRI between the perfusion-weighted imaging (PWI) lesion and the smaller diffusion-weighted imaging (DWI) lesion (PWI-DWI mismatch), clinical-DWI mismatch (CDM) has been proposed as a new diagnostic marker of brain tissue at risk of infarction in acute ischemic stroke. The Alberta Stroke Program Early CT ...

BACKGROUND AND PURPOSE: Echocardiography to select stroke patients for targeted treatments, such as anticoagulation (AC), to reduce recurrent stroke risk is controversial. The authors' objective was to evaluate the cost-effectiveness of imaging strategies that use transthoracic (TTE) and transesophageal (TEE) echocardiography for identifying intracardiac thrombus in new stroke patients. METHODS: ...

Up to 40% of acute ischaemic strokes in young adults are cryptogenic in nature, that is, no cause is determined. In more than half of these patients, patent foramen ovale (PFO) is seen along with an increased incidence of atrial septal aneurysm. The commonest method of investigation is echocardiography (preferably ...

BACKGROUND AND PURPOSE: Basilar artery occlusion (BAO) is a stroke subtype with poor prognosis, but recanalizing therapies have been reported to be effective. We investigated whether initial admission to telemedically linked general hospitals with subsequent stroke-center transfer is related to poorer outcome than direct admission to stroke centers. METHODS: All ...

OBJECTIVES: Most of existing stroke scoring systems have limited ability to evaluate patients with cerebrovascular events in the vertebrobasilar territory. We devised a new scale, the Israeli Vertebrobasilar Stroke Scale (IVBSS) in order to directly and more accurately assess clinical deficits of patients with vertebrobasilar stroke. The present study measured ...

BACKGROUND: Given the constraints of resources, thrombolysis for acute ischemic stroke (AIS) is under evaluation in developing countries. Prothrombin time (PT), platelet count and activated partial thromboplastin time (aPTT) may not be feasible within the time window. AIM: To evaluate the safety and efficacy of thrombolysis in selected patients without ...

BACKGROUND: Patients with acute stroke often have a striking lack of knowledge of causes, warning signs, and risk factors. Lack of knowledge may lead to inappropriate secondary prevention behavior. We investigated the knowledge of patients with a TIA or minor stroke about specific aspects of their disease 3 months after ...

Transient ischemic attack (TIA) is a precursor to ischemic stroke. At least half of patients with TIA have a new, small ischemic lesion demonstrable on magnetic resonance imaging using a diffusion weighted sequence. The risk of subsequent major stroke is 10-20% in the next 3 months with much of that ...
