Item type:Publication, Accuracy of Diffusion-Weighted Imaging in the Diagnosis of Stroke in Patients With Suspected Cerebral Infarct(2013); ; ; <jats:sec> <jats:title>Background and Purpose—</jats:title> <jats:p>The accuracy of diffusion-weighted imaging (DWI) for the diagnosis of acute cerebral ischemia among patients with suspected ischemic stroke arriving to an emergency room has not been studied in depth.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods—</jats:title> <jats:p>DWI was performed in 712 patients with acute or subacute focal symptoms that suggested an acute ischemic stroke (AIS), 609 of them with AIS.</jats:p> </jats:sec> <jats:sec> <jats:title>Results—</jats:title> <jats:p>DWI demonstrated a sensitivity of 90% and specificity of 97%, a positive likelihood ratio of 31 and a negative likelihood ratio of 0.1 for detecting AIS. The overall accuracy was 95%. Of those patients who demonstrated abnormal DWI studies, 99.5% were AIS patients, and of those patients with normal DWI studies 63% were stroke mimics.</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions—</jats:title> <jats:p>DWI is accurate in detecting AIS in unselected patients with suspected AIS; a negative study should alert for nonischemic conditions.</jats:p> </jats:sec>1Scopus© Citations 44 1 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Clinical prediction of aspiration in acute neurological patients(2005-12-01); ; ; López O., AngélicaGlottic dysfunction is a frequent condition in patients with acute neurological diseases: the incidence in stroke patients is between 45-51% increasing mortality three times. The principal complication is aspiration, which demands the involvement of pulmonary physicians and neurologists. The purpose of this study is to evaluate wet voice, water swallow test and cervical auscultation as clinical predictors of aspiration using endoscopical observation as a gold standard. During a period of one year we have prospectively evaluated these tests in acute neurological patients hospitalized in an intensive care unit. Wet voice, 3 oz water swallow test and cervical auscultation demonstrated sensibilities of 66.7, 88.9 and 77.8%, with a respective specificity of 85.2, 59.3 and 77.8%. Positive predictive values were 60, 42.1 and 53.8%, with negative predictive values of 88.5, 94.1 and 91.3% respectively. These results support the utility of clinical aspiration screening as a simple and valuable technique that can be done at the bedside.4
