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)
Long PLUNC1 (LPLUNC1, C20orf114) is a member of a family of poorly described proteins (PLUNCS) expressed in the upper respiratory tract and oral cavity, which may function in host defence. Although it is one of the most highly expressed genes in the upper airways and has been identified in sputum and nasal secretions by proteomic studies, localisation of(More)
To the Editor: Primary bilateral tha-lamic gliomas are exceedingly rare and usually present with behavioral and cognitive abnormalities, sparing motor and sensory functions. 1 Brain imaging reveals bilateral homogeneous enlargement of thalamic nuclei, which appear hyperintense on T2-weighted imaging. Case Report A 42-year-old woman was seen for 6-month(More)

The use of unmanned vehicle networks for diverse applications is becoming widespread. It is generally hard to program unmanned vehicle networks as a " whole " , however. The coordination of multiple vehicles requires careful planning through intricate human intervention, and a high degree of informality is implied in what concerns the specification of a "(More)
OBJECTIVE Analyze the cases of posterior reversible encephalopathy syndrome (PRES) admitted in a Neurology Department during an 8-year period. METHOD Retrospective observational study in a central hospital in the north of Portugal. RESULTS 14 patients were identified, mean age 52.3 years. Precipitating factors included: eclampsia, isolated arterial(More)
We report the case of a 17-year-old male on long-term steroid therapy for minimal lesion glomerulopathy who, after an upper respiratory infection, presented with Haemophilus influenzae type b meningitis. Twenty-four hours later he developed depression of consciousness which progressed to coma and left hemiparesis. Brain magnetic resonance imaging (MRI)(More)
A 47-year-old woman was seen for progressive behavioural and cognitive disturbances slowly evolving over a 1-year period. Neuropsychological evaluation disclosed moderate to severe impairment of all cortical functions. Besides this no other clinical abnormality was found. MRI diffusion weighted imaging disclosed hyperintense cortical lesions in a(More)
Cerebral Magnetic Resonance imaging in acute postictal period is performed to exclude structural processes that can be responsible for the epileptic activity. Sometimes, the findings are the result of the epileptic activity, and not the cause reflecting the pathophysiologic changes during epileptic activity. In this paper we describe a patient with status(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)
