To the Editor: Typical clinical features of Wernicke's encephalopathy are caused by vitamin B 1 deficiency and include confusion, ataxia, and ophthalmoplegia. 1,2 Although it can occur in all malnourished patients, it is far more frequent in alcoholics. 1,2 Brain MRI is a central diagnostic tool that usually discloses high signal lesions in T2-weighted(More)
A case of isolated velopalatine paralysis in an 8-year-old boy is presented. The symptoms were sudden-onset of nasal speech, regurgitation of liquids into the nose and dysphagia. Brain MRI and cerebrospinal fluid examination were normal. Infectious serologies disclosed an antibody arrangement towards parvovirus B19 that was typical of recent infection. In(More)
Wallerian degeneration (WD) after ischemic stroke has been associated to persistent motor impairment, but signal intensity changes on conventional magnetic resonance imaging (MRI) are generally not detected until four weeks after the event. We report a 54 year old male patient, referred to our hospital for sudden-onset left hemiparesis. Cerebral CT showed(More)
Antibodies against N-methyl-D-aspartate receptor (NMDAR) are identified in the form of immune-mediated encephalitis in which typical manifestations include neuropsychiatric symptoms, seizures, abnormal movements, dysautonomia and hypoventilation. The authors report two cases of anti-NMDAR encephalitis with different presentations and patterns of(More)
Multiple supratentorial abscesses caused by Listeria monocytogenes are rare. We report the simultaneous occurrence of multiple supratentorial and brainstem abscesses due to Listeria, in a patient under corticotherapy for an exacerbation of ulcerative colitis. MR imaging features before and after successful conservative treatments are depicted. In(More)
UNLABELLED It was suggested that intravenous thrombolysis (IT) leads to larger extent recanalization in cardioembolic stroke. In this work we assess if this has beneficial clinical traduction. METHOD We evaluated 177 patients undergoing IT, which were categorized into cardioembolic (CE) and non-cardioembolic (NCE). National Institutes of Health Stroke(More)
BACKGROUND AND PURPOSE Dramatic recovery (DR) after thrombolysis is dependent of vessel recanalization and is predictive of favorable clinical outcome. Successful recanalization is not equivalent to DR. Our objective was to assess its frequency and evaluate clinical and biochemical predictors and their prognosis. METHODS We analyzed prospectively(More)
The context of the Internet of Things and the growing use of mobile devices have demanded wireless communication alternatives, complementary to radio frequency. As a promising alternative, optical wireless communication has emerged, due to significant deployments in solid-state lighting technology. Light-emitting diodes have been adopted in many domains,(More)
