RESUMO Antecedentes: As ataxias espinocerebelares (SCA) são um grupo de doenças neurodegenerativas caracterizadas pela deterioração do equilíbrio e da funcionalidade, que tende a acompanhar a progressão da doença. Não existe uma ligação estabelecida entre os marcadores clínicos formais de gravidade e escores funcionais e de equilíbrio que possam orientar as equipes de reabilitação. Objetivo: Avaliar a relação entre escalas funcionais e de gravidade da ataxia, buscando identificar pontos de corte para a perda funcional relacionados aos escores de gravidade e aos patamares de Risco de Quedas. Métodos: Uma amostra consecutiva de 89 pacientes com diagnóstico molecular de SCA (31-SCA2 e 58-SCA3) foram avaliados para funcionalidade MIF-AVDs (Medida de independência funcional-Atividades da vida diária) e Lawton-AIVDs (Atividades instrumentais da vida diária), equilíbrio (EEB-escala de Equilíbrio de Berg), e gravidade da ataxia (SARA-escala para avaliação e graduação de ataxia). Resultados: Os principais pontos de corte de deficiência foram: com 12 pontos no SARA começa a necessidade de supervisão para MIF-AVDs e com 14 pontos no SARA começa a necessidade de supervisão para Lawton-AIVDs. Os primeiros itens a necessitar de assistência foram “expressão” e “compras”, respectivamente. Com 20 pontos no SARA os pacientes eram dependentes em todos os itens MIF/LAWTON. O item com maior impacto na discriminação entre dependentes e independentes foi “meio de transporte” na Lawton e o domínio “locomoção” na MIF. O escore médio no SARA foi de 9,9 pontos para pacientes classificados com baixo risco na EEB, 17,4 para médio risco e 25,2 para alto risco. Conclusões: A análise da correlação entre a gravidade da ataxia e as escalas funcionais pode ser um importante guia no entendimento da progressão da dependência funcional em indivíduos com SCA.

ABSTRACT Background: Spinocerebellar ataxias (SCAs) are a group of neurodegenerative diseases characterized by deterioration of balance and functionality that tends to follow disease progression. There is no established link between formal clinical markers for severity and functional/balance scores that could guide rehabilitation teams. Objective: To evaluate the relationship between functional scales and ataxia severity in order to identify cutoff landmarks for functional loss and estimate the mean SARA (Scale for Assessment and Rating of Ataxia) score for the risk ratings for falls on the BBS (Berg Balance Scale). Methods: Consecutive patients with a molecular diagnosis of SCA (total 89: 31 with SCA2 and 58 with SCA3) were assessed for functionality FIM-ADL (Functional Independence Measure-activities of daily living and Lawton-IADL (instrumental activities of daily living), balance (BBS) and disease severity (SARA). Results: The main disability cutoff landmarks were that the need for supervision for FIM-ADL starts with 12 points on SARA and the need for supervision for Lawton-IADL starts with 14 points on SARA. The first items to require assistance were “expression” and “shopping”, respectively. At 20 points on SARA, patients were dependent on all FIM and Lawton items. The item with the greatest impact on distinguishing dependents from independents was “means of transport” in Lawton-IADL and the domain “locomotion” in FIM-ADL. The mean SARA score for patients classified as low risk in the BBS was 9.9 points, and it was 17.4 for medium risk and 25.2 for high risk. Conclusions: Analysis on the correlation between the severity of ataxia and functional scales can form an important guide for understanding the progression of functional dependence among individuals with SCAs.

INTRODUCTION: Chronic obstructive pulmonary disease is characterized by progressive and partially reversible obstruction of pulmonary airflow. AIM: To characterize swallowing in patients with chronic obstructive pulmonary disease and correlate the findings with the degree chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, and smoking. METHOD: We conducted a prospective cohort study of 19 patients (12 men and 7 women; age range, 50-85 years) with confirmed medical diagnosis of chronic obstructive pulmonary disease. This study was performed in 2 stages (clinical evaluation and functional assessment using nasolaryngofibroscopy) on the same day. During both stages, vital signs were checked by medical personnel. RESULTS: Clinical evaluation of swallowing in all patients showed the clinical signs of cough. The findings of nasolaryngofibroscopy highlighted subsequent intraoral escape in 5 patients (26.5%). No patient had tracheal aspiration. There was no association of subsequent intraoral escape with degree of chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, or smoking. CONCLUSION: In patients with chronic obstructive pulmonary disease, there was a prevalence of oral dysphagia upon swallowing and nasolaryngofibroscopy highlighted the finding of subsequent intraoral escape. There was no correlation between intraoral escape and the degree of chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, or smoking.

INTRODUÇÃO: A incidência da disfagia orofaríngea, em pacientes com acidente vascular encefálico (AVE), varia de 20% a 90% na literatura. Estudos correlacionam a localização do AVE com a presença de disfagia e outros não a correlacionam. OBJETIVO: Correlacionar a lesão encefálica com a disfagia em pacientes com diagnóstico de AVE, considerando-se o tipo e a localização do AVE. MÉTODO: Estudo prospectivo realizado no Hospital de Clínicas com 30 pacientes com AVE, sendo 18 do sexo feminino e 12 do masculino. Todos realizaram avaliações clínica e nasolaringofibroscópica da deglutição (FEES®) e divididos pela localização da lesão: córtex cerebral, córtex cerebelar e áreas subcorticais e tipo: hemorrágico, isquêmico ou transitório. RESULTADOS: Dos 30, 18 apresentaram AVE tipo isquêmico, dois hemorrágico e 10 transitório. Sobre a localização, 10 a apresentaram no córtex cerebral, três nos córtices cerebral e cerebelar, três no córtex cerebral e subcortical, um nos córtices cerebral, cerebelar e subcortical e três subcortical. Na avaliação clínica houve predomínio da disfagia oral em pacientes com lesão no córtex cerebral e subcortical do tipo isquêmico. No FEES® a diminuição da sensibilidade laríngea predominou no córtex cerebral e tipo isquêmico. Os resíduos faríngeos em valéculas epiglóticas associadas com recessos piriformes predominaram no córtex cerebral em todas as consistências e tipo isquêmico. Um paciente com lesão nos córtices cerebral e cerebelar apresentou penetração laríngea e aspiração traqueal nas consistências líquida e mel, do tipo isquêmico. CONCLUSÃO: Houve predomínio da disfagia na localização da lesão no córtex cerebral e do tipo isquêmico.

INTRODUCTION: In the literature, the incidence of oropharyngeal dysphagia in patients with cerebrovascular accident (AVE) ranges 20-90%. Some studies correlate the location of a stroke with dysphagia, while others do not. OBJECTIVE: To correlate brain injury with dysphagia in patients with stroke in relation to the type and location of stroke. METHOD: A prospective study conducted at the Hospital de Clinicas with 30 stroke patients: 18 women and 12 men. All patients underwent clinical evaluation and swallowing nasolaryngofibroscopy (FEES®), and were divided based on the location of the injury: cerebral cortex, cerebellar cortex, subcortical areas, and type: hemorrhagic or transient ischemic. RESULTS: Of the 30 patients, 18 had ischemic stroke, 10 had hemorrhagic stroke, and 2 had transient stroke. Regarding the location, 10 lesions were in the cerebral cortex, 3 were in the cerebral and cerebellar cortices, 3 were in the cerebral cortex and subcortical areas, and 3 were in the cerebral and cerebellar cortices and subcortical areas. Cerebral cortex and subcortical area ischemic strokes predominated in the clinical evaluation of dysphagia. In FEES®, decreased laryngeal sensitivity persisted following cerebral cortex and ischemic strokes. Waste in the pharyngeal recesses associated with epiglottic valleculae predominated in the piriform cortex in all lesion areas and in ischemic stroke. A patient with damage to the cerebral and cerebellar cortices from an ischemic stroke exhibited laryngeal penetration and tracheal aspiration of liquid and honey. CONCLUSION: Dysphagia was prevalent when a lesion was located in the cerebral cortex and was of the ischemic type.
