Nationwide Access to Endovascular Treatment for Acute Ischemic Stroke in Portugal
Dias, Mariana Carvalho; Reis, Ricardo Soares dos; Santos, João Vasco; Nunes, Ana Paiva; Ferreira, Patricia; Maia, Bruno; Fragata, Isabel; Reis, JoaoIntroduction: Since the publication of endovascular treatment trials and European Stroke Guidelines, Portugal has re-organized stroke healthcare. The nine centers performing endovascular treatment are not equally distributed within the country, which may lead to differential access to endovascular treatment. Our main aim was to perform a descriptive analysis of the main treatment metrics regarding endovascular ...

Chronic rhinosinusitis: Correlation between the symptoms and score lund-mackay
Sá Breda, Miguel; Miranda, Daniel; Pereira, Sara; Silva, Diana; Menezes, Ana; Moreira, Filipa; Ribeiro, Daniela; Rocha, Jaime; Dias, LuisIntroduction: The correct diagnosis of chronic rhinosinusitis with (CRSwNP) or without (CRSsNP) polyposis implies a well performed anamnesis and physical examination to, judiciously, request a paranasal sinuses CT scan (CT NS)1. Lund and Mackay suggested a paranasal sinuses opacification score (SLM)2 based on CT NS.Objective: To test a possible correlation between clinical findings and SLM.Methods: Retrospectiv...
Brain magnetic resonance spectroscopy classifiers
Alves, Victor; Oliveira, Susana Marta Fonseca de; Rocha, JaimeDuring the last decade, the Magnetic Resonance Spectroscopy modality has become an integrant part of the diagnostic routine. However, the visual interpretation of these spectra is difficult and few clinicians are trained to use the technique. In this study, sixty-eight spectra obtained from twenty-two multi-voxel spectroscopies were classified using three well-known classification algorithms: K-Nearest Neighbor...
Wallerian degeneration after stroke: a new prognostic factor?.
Soares-Fernandes, João; Beleza, Pedro; Ribeiro, Manuel; Maré, Ricardo; Almeida, Fátima; Rocha, JaimeWallerian 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 right fronto-parietal infarct (middle cerebral artery st...
Spinal subdural haematoma.
Ribeiro, Manuel; Cerqueira, João; Fernandes, João; Alegria, Carlos; Rocha, JaimeSpinal subdural haematoma is a rare pathology and may cause severe neurological deficit. In this paper a case of acute spinal subdural haematoma of multifactorial etiology--traumatic versus iatrogenic--is presented, in which the clinical evaluation, Computerized Tomography and Magnetic Resonance were of utmost importance as far as the early diagnosis is concerned, allowing therefore decompressive surgery to avo...
Reverse crossed cerebellar diaschisis.
Ribeiro, Manuel; Beleza, Pedro; Fernandes, João; Almeida, Fátima; Rocha, JaimeCerebral 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 epilepticus who has developed hemicerebellar involvement...
