The Brazilian Practice Guidelines for Stroke Rehabilitation – Part II, developed by the Scientific Department of Neurological Rehabilitation of the Brazilian Academy of Neurology (Academia Brasileira de Neurologia, in Portuguese), focuses on specific rehabilitation techniques to aid recovery from impairment and disability after stroke. As in Part I, Part II is also based on recently available evidence from randomized controlled trials, systematic reviews, meta-analyses, and other guidelines. Part II covers disorders of communication, dysphagia, postural control and balance, ataxias, spasticity, upper limb rehabilitation, gait, cognition, unilateral spatial neglect, sensory impairments, home rehabilitation, medication adherence, palliative care, cerebrovascular events related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the future of stroke rehabilitation, and stroke websites to support patients and caregivers. Our goal is to provide health professionals with more recent knowledge and recommendations for better rehabilitation care after stroke.

Decompressive craniectomy (DC) reduces mortality and improves outcome in patients with massive brain infarctions. The role of intracranial pressure (ICP) monitoring following DC for stroke has not been well established. Methods: We evaluated 14 patients admitted to a tertiary hospital with malignant middle cerebral artery infarctions, from October 2010 to February 2015, who underwent DC and had ICP monitoring. Patients with and without episodes of ICP elevation were compared. Results: Fourteen patients were submitted to DC and had ICP monitoring following the procedure during the period. Ten patients (71.4%) had at least one episode of sustained elevated ICP in the first seven days after surgery. Maximal ICP levels had no correlation with age, time to hemicraniectomy or Glasgow Coma Scores at admission, but had a trend toward correlation with the National Institutes of Health Stroke Scale score at admission (p = 0.1). Ventriculitis occurred in 21.4% of the patients. Conclusions: High ICP episodes and ventriculitis were common in patients following hemicraniectomy for malignant middle cerebral artery strokes. Therefore, the implications of ICP and benefits of the procedure should be firmly established.

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.

Estudos neurossonológicos, especialmente o Doppler transcraniano (DTC) e o duplex transcraniano codificado a cores (DTCC), apresentam elevados níveis de especificidade e sensibilidade quando utilizados como exames complementares no diagnóstico de morte encefálica (ME). Um grupo de peritos do Departamento Científico de Doppler transcraniano da Academia Brasileira de Neurologia criou uma força-tarefa de forma a determinar os critérios neurossonológicos para os seguintes aspectos no diagnóstico de ME no Brasil: metodologia do DTC; metodologia do DTCC; treinamento e habilidades em Neurossonologia; diagnóstico de parada circulatória encefálica e documentação do exame para a ME. Os resultados deste encontro foram apresentados neste artigo. Neurosonological studies, specifically transcranial Doppler (TCD) and transcranial color-coded duplex (TCCD), have high level of specificity and sensitivity and they are used as complementary tests for the diagnosis of brain death (BD). A group of experts, from the Neurosonology Department of the Brazilian Academy of Neurology, created a task force to determine the criteria for the following aspects of diagnosing BD in Brazil: the reliability of TCD methodology; the reliability of TCCD methodology; neurosonology training and skills; the diagnosis of encephalic circulatory arrest; and exam documentation for BD. The results of this meeting are presented in the current paper.

Guillain-Barre syndrome (GBS) has been described as adverse event following different types of vaccines, such as influenza, varicella, polio virus and hepatitis B1. Since 2009 with the emergence of the pandemic H1N1 influenza virus infection in humans, new vaccines have been developed for influenza A (H1N1) as a preventive strategy to reduce transmission, protect groups at increased risk of infection, and decrease complications and death2. In this context, we report two adults who developed GBS after H1N1 immunization. Guillain-Barre syndrome [...]

A dissecção espontânea das artérias carótidas e vertebrais (DEACV) é considerada uma causa rara de acidente vascular cerebral, particularmente em países com população multiétnica. O objetivo desse estudo foi avaliar características clínicas e de neuroimagem dos pacientes com DEACV em uma população multiétnica. Foram estudados 66 pacientes com diagnóstico de DEACV em dois hospitais terciários de São Paulo. Aplicou-se um questionário inicial e os pacientes foram seguidos prospectivamente. Dos pacientes estudados, 82% eram brancos, 53% eram homens e a média de idade foi 41,7 anos. Os fatores de risco cardiovasculares mais freqüentes foram hipertensão arterial e tabagismo. Outros aspectos avaliados foram história prévia de enxaqueca, tratamento inicial e prognóstico. Concluiu-se que apesar da população estudada ser multiétnica, houve um marcante predomínio de brancos. A análise das características clínicas e de neuroimagem dos pacientes com DEACV possibilita um melhor conhecimento da doença, levando a um diagnóstico precoce e tratamento mais adequado. Spontaneous dissection of the carotid and vertebral arteries (SDCVA) is considered a rare cause of stroke, particularly in countries with multiethnic population. The objective was to evaluate the clinical and neuroimaging features of patients with SDCVA from a multiethnic population. Sixty-six patients diagnosed with SDCVA were studied at two tertiary hospitals at São Paulo. An initial questionnaire was completed and patients were followed prospectively. Among the patients studied, 82% were caucasian, 53% were male and the average age was 41.7 years old. The most frequent cardiovascular risk factors found were systemic hypertension and tobacco use. Other aspects evaluated were history of previous migraine, initial treatment and prognosis. In conclusion, although the population studied was multhiethnic, there was a marked predominance of caucasians. The analysis of clinical and neuroimaging data from patients with SDCVA allows a better understanding of the disease, leading to an earlier diagnosis and more appropriate treatment.

A doença celíaca (DC, enteropatia sensível ao glúten) é desordem caracterizada por mal absorção causada por reação alérgica ao glúten, proteína presente em diversos cereais. As manifestações iniciais ocorrem nas primeiras quatro décadas de vida, sendo cerca de duas vezes mais freqüente no sexo feminino. DC pode estar associada a largo espectro de manifestações neurológicas incluindo ataxia cerebelar, epilepsia, demência, neuropatia, miopatia e leucoencefalopatia multifocal. Relatamos três casos de pacientes com manifestações neurológicas da DC: um com ataxia cerebelar, outro com epilepsia e o último com déficit cognitivo. O diagnóstico de DC foi estabelecido com base em testes sorológicos (anticorpos antiendomísio e antigliadina) e biópsia intestinal. Em dois pacientes as alterações neurológicas precederam as gastrointestinais. Em todos os casos a dieta livre de glúten não influenciou o quadro neurológico. Concluímos que o diagnóstico de DC deve ser considerado em pacientes com alterações neurológicas de etiologia indeterminada, incluindo ataxia, epilepsia e demência. Uma dieta sem glúten, a base do tratamento das manifestações gastrointestinais, não foi eficiente em melhorar os sintomas neurológicos em nossos pacientes. Celiac disease (CD/ Nontropicalsprue, gluten-sensitive enteropathy) is a malabsortive condition in which an allergic reaction to the cereal grain-protein gluten (present in wheat, rye and barley) causes small intestine mucosal injury. The onset is in the first four decades of life, with a female to male ratio of 2:1. It may be associated with a wide spectrum of neurological manifestations including cerebellar ataxia, epileptic seizures, dementia, neuropathy, myopathy and multifocal leucoencephalopathy. We report three patients with neurological manifestations related with CD: one with cerebellar ataxia, one with epilepsy and one with cognitive impairment. The diagnosis of CD was confirmed by serologic tests (antiendomysial and antigliadin antibodies) and biopsy of the small intestine. In two patients the neurological symptoms preceded the gastrointestinal abnormalities and in all of them gluten restriction failed to improve the neurological disability. Conclusion: CD should be ruled out in the differential diagnosis of neurological dysfunction of unknown cause, including ataxia, epilepsy and dementia. A gluten free diet, the mainstay of treatment, failed to improve the neurological disability.

With the advent of time-dependent thrombolytic therapy for ischemic stroke it has become increasingly important for stroke patients to arrive at the hospital quickly. This study investigated the time that our patients took since the recognition of the symptoms until the stroke diagnosis in a hospital in the city of São Paulo. We concluded that in our hospital medical personnel and paramedics did not consider stroke as a medical emergency before neurological evaluation. Social problems as lack of access to an effective emergency medical service are another important factor that was responsible for patient's delay. Our study was important in order to identify the problems that stroke patients face in our country until the diagnosis is established. Com o uso da terapia trombolítica para acidente vascular cerebral (AVC) isquêmico, torna-se importante o tempo de chegada do paciente nos serviços de referência. Neste estudo foi investigado o tempo entre o reconhecimento dos sintomas e o diagnóstico de AVC em hospital universitário na cidade de São Paulo. Concluímos que neste serviço, os profissionais da saúde não consideravam AVC uma emergência antes da avaliação neurológica. Outro fator que contribuiu para o atraso na chegada ao hospital foi dificuldade de transporte aos serviços públicos. Este estudo foi importante para a identificação dos problemas que os pacientes com AVC enfrentam para ter o diagnóstico e tratamento, o que possibilitou implantação de programas para melhora do atendimento.
