Escalas de comprometimento neurológico são utilizadas na avaliação de novos tratamentos, no acompanhamento da evolução clínica e em decisões terapêuticas. Estudamos a confiabilidade de três escalas: a Escala de Rankin (ER), o Índice de Barthel (IB) e a National Institute of Health Stroke Scale (NIHSS) versadas em português, em 51 indivíduos com acidente vascular cerebral, estimando a concordância entre resultados de diferentes examinadores. Utilizamos os coeficientes de concordância Kappa e Coeficiente de Correlação Intraclasse. A ER teve coeficientes moderados, substanciais ou excelentes. No IB estes foram substanciais ou excelentes nos totais e nos itens, assim como quando foi estratificado em agrupamentos prognósticos e funcionais. A NIHSS apresentou coeficientes excelentes nos totais, substanciais nos itens e moderados e excelentes nas estratificações em grupos de pontos e de itens afins. Estes resultados indicam que as versões em português da ER, o IB e a NIHSS apresentam adequada confiabilidade.

This study aimed to develop a short version of an instrument to detect cognitive impairment in stroke patients, investigate which cognitive dimensions best discriminate between stroke patients and healthy adults and to graphically analyze the relationships among the neuropsychological variables and groups. This pilot study included 94 adults (49 post-stroke and 45 neurologically healthy) who answered the Brief Neuropsychological Assessment Battery NEUPSILIN for patients with expressive aphasia (NEUPSILIN-Af) to assess orientation, perception, memory, praxis, executive functions, oral language, and academic achievement (written language and arithmetic). The IRT Rasch model for dichotomous data indicated the exclusion of items that could not be used to discriminate performances. ROC curves indicated that only the orientation, oral language, academic achievement, and executive function dimensions could be used to differentiate between the clinical and healthy groups. Graphical analysis indicated that independently of the relation among variables, orientation and executive functions tasks are essentials in the neuropsychological assessments. This study contributes to the development of specific and sensitive neuropsychological instruments to assess stroke patients and to better understand the common deficits present in this clinical population.

Background: The global COVID-19 pandemic has had a devastating effect on global health, resulting in a strain on healthcare services worldwide. The faster a patient with acute ischemic stroke (AIS) receives reperfusion treatment, the greater the odds of a good functional outcome. To maintain the time-dependent processes in acute stroke care, strategies to reorganize infrastructure and optimize human and medical resources were needed., Methods: Data from AIS patients who received thrombolytic therapy were prospectively assessed in the emergency department (ED) of Hospital de Clínicas de Porto Alegre from 2019 to 2021. Treatment times for each stage were measured, and the reasons for a delay in receiving thrombolytic therapy were evaluated., Results: A total of 256 patients received thrombolytic therapy during this period. Patients who arrived by the emergency medical service (EMS) had a lower median door-to-needle time (DNT). In the multivariable analysis, the independent predictors of DNT >60 min were previous atrial fibrillation (OR 7) and receiving thrombolysis in the ED (OR 9). The majority of patients had more than one reason for treatment delay. The main reasons were as follows: delay in starting the CT scan, delay in the decision-making process after the CT scan, and delay in reducing blood pressure. Several actions were implemented during the study period. The most important factor that contributed to a decrease in DNT was starting the bolus and continuous infusion of tPA on the CT scan table (decreased the median DNT from 74 to 52, DNT ≤ 60 min in 67% of patients treated at radiology service vs. 24% of patients treated in the ED). The DNT decreased from 78 min to 66 min in 2020 and 57 min in 2021 ( p = 0.01)., Conclusion: Acute stroke care continued to be a priority despite the COVID-19 pandemic. The implementation of a thrombolytic bolus and the start of continuous infusion on the CT scan table was the main factor that contributed to the reduction of DNT. Continuous monitoring of service times is essential for improving the quality of the stroke center and achieving better functional outcomes for patients., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Klu, Souza, Carbonera, Secchi, Pille, Rodrigues, Brondani, Almeida, Dal Pizzol, Camelo, Mantovani, Oldoni, Tessari, Nasi and Martins.)

Scales for the assessment of neurological impairment are employed in clinical trials, outcome evaluation and in therapeutic decisions. We evaluated the reliability of the Portuguese version of the Rankin Scale (RS), Barthel Index (BI) and the NIHSS (National Institute of Health Stroke Scale) in 51 stroke patients, estimating the agreement of the results for examiners. The interrater reliability was measured using the Kappa Coefficient and Intraclass Correlation Coefficient. The RS showed moderate, substantial and excellent coefficients of agreement. The BI showed from substantial to excellent coefficients of agreement as a whole and also for its constituents. This scale was stratified in prognostic and functional groups, both presenting coefficients of agreement from substantial to excellent. The NIHSS presented excellent agreement on its total and substantial agreements on its individual items. The NIHSS was also stratified in groups of points, which presented moderate or excellent coefficient, and in groups of congruous items, wich showed a moderate to excellent agreement. These results suggest that the Portuguese version of the RS, BI and the NIHSS present adequate reliability.

Progressive bulbar palsy, also called Fazio -Londe disease, is characterized by progressive impairment of cranial nerves in children. It was first reported by Fazio in 1892 and until now only 30 cases have been published in the literature. Both sexes can be affected and clinical course can be divided on early (< 6 years age, predominance of respiratory symptoms) and late course (6-20 years of age, predominance of motor symptoms on superior limbs). We report a 4 years old boy that started with intense stridor and respiratory distress, initially being diagnosed as an acute asthma attack. Clinical signs worsened and 12 months latter he already had impairment of cranial nerves V, VII, VIII, IX and X confirmed by clinical examination and neurophysiological evaluation.
