- Diversity in anti-N-methyl-D-aspartate receptor encephalitis: case-based evidencePublication . Pinho, J; Rocha, J; Rodrigues, M; Pereira, J; Maré, R; Ferreira, C; Lourenço, E; Beleza, PAntibodies 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 progression. The first patient presented with status epilepticus and later developed psychosis, pyramidal signs and diffuse encephalopathy. The second patient presented with acute psychosis followed a week later by seizures, dystonia, rigidity, oromandibular dyskinesias and dysautonomia. Possible mechanisms responsible for the clinical manifestations of this disease are discussed in light of recently described additional clinical and laboratory findings.
- Dramatic recovery after IV thrombolysis in anterior circulation ischemic stroke: Predictive factors and prognosisPublication . Rocha, J; Pinho, J; Varanda, S; Amorim, J; Rocha, JR; Maré, R; Ferreira, CBACKGROUND 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 registered data from January 2007 to September 2012. All patients with anterior circulation stroke and NIHSS≥10 were included. Improvement of ≥10 or a score ≤3 24h after thrombolysis was defined as DR. RESULTS: In the 230 patients included, DR frequency was 23% (53 patients). DR group had lower admission NIHSS (14 vs 17, p=0.024), less total anterior circulation infarcts (p=0.009), more partial anterior circulation infarcts (p=0.003) and lower blood glucose on admission (118 vs 128mg/dL, p=0.013). All patients with DR had an Alberta Stroke Program Early CT Score (ASPECTS) ≥7, vs 89.3% without DR (p=0.013). Arterial recanalization, defined as hyperdense middle cerebral artery sign disappearance on control CT, was more frequent in the DR group (68.4% vs 14.1%, p<0.001). Intracranial hemorrhage on 24h-control CT scan was less frequent in the DR group (p<0.001). Multinomial logistic regression analysis showed that ASPECTS score was an independent predictor of DR (OR=2.35, 95%CI=1.32-4.16, p=0.003) and CT evidence of recanalization was independently associated with DR (OR=11.60, 95%CI, 3.02-44.53, p<0.001). CONCLUSION: DR is a frequent occurrence. ASPECTS score is an independent predictor of DR, which is also independently associated with CT evidence of middle cerebral artery recanalization.

- Intravenous thrombolysis is more effective in ischemic cardioembolic strokes than in non-cardioembolic?Publication . Rocha, S; Pires, A; Gomes, J; Sousa, F; Pinho, J; Rodrigues, M; Ferreira, C; Machado, A; Maré, R; Fontes, JRIt 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 Scale (NIHSS) and modified Rankin scale were compared. RESULTS: The mean age was 67.4±12.01 and 53.8% were male. The mean NIHSS was: 14 (admission), 9 (24 h) and 6 (discharge), similar in subgroups. The difference between NIHSS at admission and 24 hours was 4.17±4.92 (CE: 4.08±4.71; NCE: 4.27±5.17, p=0.900) and at admission and discharge there was an average difference of 6.74±5.58 (CE: 6.97±5.68; NCE: 6.49±5.49, p=0.622). The mRS at discharge and 3 months was not significantly different by subtype, although individuals whose event was NCE are more independent at 3 months. CONCLUSION: Ours findings argue against a specific paper of IT in CE. It can result from heterogeneity of NCE group
- Isolated velopalatine paralysis associated with parvovirus B19 infectionPublication . Soares-Fernandes, JP; Maré, RA 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 the absence of other positive data, the possibility of a correlation between the tenth nerve palsy and parvovirus infection is discussed.
