The influence of patient’s knowledge about stroke in Brazil: a cross sectional study / A influência do conhecimento do paciente sobre o AVC no Brasil: um estudo transversal

Little is known about stroke patients’ awareness about the warning signs of stroke and its therapeutic time window in Brazil. Method We interviewed consecutive patients with acute stroke admitted to a terciary public hospital in Brazil. Data collected included demographics, mode of arrival, National Institutes of Health Stroke Scale (NIHSS) scores and knowledge of stroke warning signs and therapeutic time window. Early arrival was defined as within 4.5 hours of symptoms onset. Results Although 66.2% of patients knew the warning signs of stroke, only 7.8% reported to know that stroke had a limited therapeutic time window. Stroke severity measured by the NIHSS was independently associated with early arrival, but not knowledge of stroke signs and symptoms. Conclusion Knowledge about stroke symptoms was not a predictor of early arrival. .

Pouco se sabe sobre o conhecimento dos pacientes com acidente vascular cerebral (AVC) acerca dos sinais de alarme da doença e sua janela terapêutica no Brasil. Método Foram entrevistados consecutivamente os pacientes com AVC agudo internados em um hospital público terciário no Brasil. Os dados coletados incluíram dados demográficos, o modo de chegada, escala de AVC do National Institute of Health (NIH) e conhecimento sobre a janela de tempo terapêutica e os sinais de alerta do AVC através de um questionário padronizado. Chegada precoce foi definida como aquela dentro de 4,5 horas do início dos sintomas. Resultados Embora 66,2% dos pacientes sabiam os sinais de alerta do AVC , apenas 7,8% relataram saber que a doença tinha uma janela de tempo terapêutica limitada. A gravidade do AVC avaliada pela escala do NIH foi preditora de chegada precoce, mas conhecimento acerca dos sinais e sintomas do AVC não foram. Conclusão O conhecimento acerca dos sintomas do AVC não foi preditivo de chegada precoce ao hospital. .

Data collected included demographics, mode of arrival, National Institutes of Health Stroke Scale (NIHSS) scores and knowledge of stroke warning signs and therapeutic time window. Early arrival was defined as within 4.5 hours of symptoms onset. RESULTS: Although 66.2% of patients knew the warning signs of stroke, only 7.8% reported to know that stroke had a limited therapeutic time window. Stroke severity measured by the NIHSS was independently associated with early arrival, but not knowledge of stroke signs and symptoms. CONCLUSION: Knowledge about stroke symptoms was not a predictor of early arrival.

Score for atrial fibrillation detection in acute stroke and transient ischemic attack patients in a Brazilian population: the acute stroke atrial fibrillation scoring system.

OBJECTIVE: Atrial fibrillation is a common arrhythmia that increases the risk of stroke by four- to five-fold. We aimed to establish a profile of patients with atrial fibrillation from a population of patients admitted with acute ischemic stroke or transient ischemic attack using clinical and echocardiographic findings. METHODS: We evaluated patients consecutively admitted to a tertiary hospital with acute ischemic stroke or transient ischemic attack. Subjects were divided into an original set (admissions from May 2009 to October 2010) and a validation set (admissions from November 2010 to April 2013). The study was designed as a cohort, with clinical and echocardiographic findings compared between patients with and without atrial fibrillation. A multivariable model was built, and independent predictive factors were used to produce a predictive grading score for atrial fibrillation (Acute Stroke AF Score-ASAS). RESULTS: A total of 257 patients were evaluated from May 2009 to October 2010 and included in the original set. Atrial fibrillation was diagnosed in 17.5% of these patients. Significant predictors of atrial fibrillation in the multivariate analysis included age, National Institutes of Health Stroke Scores, and the presence of left atrial enlargement. These predictors were used in the final logistic model. For this model, the area under the receiver operating characteristic curve was 0.79. The score derived from the logistic regression analysis was The model developed from the original data set was then applied to the validation data set, showing the preserved discriminatory ability of the model (c statistic = 0.76). CONCLUSIONS: Our risk score suggests that the individual risk for atrial fibrillation in patients with acute ischemic stroke can be assessed using simple data, including age, National Institutes of Health Stroke Scores at admission, and the presence of left atrial enlargement.

Acute foot drop syndrome mimicking peroneal nerve injury: an atypical presentation of ischemic stroke.

Foot drop syndrome is a frequent neurologic condition usually caused by peroneal nerve damage. On rare occasions, foot drop may present as the single neurologic manifestation of intracranial lesions. We presented a 43-year-old man admitted to our hospital with acute weakness in the dorsiflexion of his right foot that appeared 3 days before admission. Brain magnetic resonance imaging diffusion-weighted sequence revealed a small area of restricted diffusion in the left frontal cortex. Three months later, his motor deficit had completely improved (modified Rankin scale score = 0). To our knowledge, this is the second report of sudden isolated foot drop caused by a cortical infarction.

Evidências sobre diagnóstico e tratamento do acidente vascular encefálico no serviço de urgência / Evidence on diagnosis and treatment of stroke in the emergency department

O acidente vascular encefálico, independentemente de ser isquêmico ou hemorrágico, é um problema de saúde pública mundial com elevada prevalência, morbimortalidade e custo financeiro. A investigação no setor de emergência busca confirmar seu diagnóstico, iniciando rapidamente as medidas terapêuticas imediatas para reduzir o dano neurológico,possivelmente revertê-lo, e tentar evitar sua recorrência precoce. O seu manejo leva a difíceis decisões terapêuticas para os neurologistas. A utilização de métodos por imagem é imprescindível nos dias atuais e vem evoluindo para dar maior precisão ao seu diagnóstico na fase hiperaguda, como também elucidar sua etiologia posteriormente. A trombólise endovenosa no acidente vascular cerebral isquêmico tem por objetivo recanalizar o vaso ocluído e reperfundir a área cerebral que pode ser salva, sendo esse tratamento aprovado e recomendado pela Academia Brasileira de Neurologia,Academia Americana de Neurologia e Sociedade Europeia de Neurologia. Apesar de não existir terapia específica aprovada para o acidente vascular cerebral hemorrágico, existem muitas medidas clínicas e cirúrgicas que podem ser implementadas no tratamento dessa doença.
