Acinic Cell Carcinoma of the Parotid Gland: A Case Report and Review of the Literature

We report on a patient who was referred to the ENT service following an incidental finding on an MRI scan of the brain. It revealed a mass in the right parapharyngeal space, and additional imaging confirmed the presence of a solid cystic expansive mass with moderate enhancement following contrast media injection. The patient was treated with a total parotidectomy followed by radiotherapy. Currently, the patient is disease-free without any complications

Teorías implícitas y modelos de formación subyacentes a la percepción de rol del profesor de Educación Física

The present study used a mixed approach of research to analyze the implicit theories and models of formation underlying the perception of the role associated with physical education teachers in Chilean university students who begin their period of training. Therefore, a sample of 77 students (57.1% male, 42.9% females) from two universities, aged between 18 and 20 years old (x: 19.2 years), was selected. The most significant results revealed high influence of previous experience on the evaluation of subjects and on the perception of the teaching role, as well as emphasis on teachers’ personal attributes and attitudes above methodological, conceptual, and value aspects. Based on that, there is a predominance of the pedagogical model and of the educational theory as implicit theories underlying the perception of teachers’ role and, alongside, an emphasis on practical formation models so to better approach work expectations related with teaching. The implications and challenges that such reality entails for universities and training centers in the discipline are analyzed.El presente estudio emplea un enfoque mixto de investigación para analizar las teorías implícitas y modelos de formación subyacentes a la percepción del rol asociado al profesor de Educación Física en estudiantes universitarios chilenos que comienzan su período de formación. Para ello, se utilizó una muestra de 77 alumnos pertenecientes a dos universidades (57,1 % de sexo masculino y 42,9% de sexo femenino) con edades entre los 18 y los 20 años (x: 19,2 años). Los resultados más significativos revelan la alta influencia de la experiencia previa en la valoración de la asignatura y en la percepción del rol docente así como un énfasis en atributos personales y actitudinales del profesor por sobre aspectos metodológicos, conceptuales y valóricos. A partir de ello, se observa el predominio del modelo pedagógico y la teoría educativa como teoría implícita subyacente a la percepción de rol docente y, con ello, el énfasis en un modelo práctico de formación para poder abordar de mejor forma la expectativa laboral ligada a la docencia. Se analizan las implicancias y desafíos que tal realidad conlleva para las universidades y centros de formación en la disciplina

European Multicenter Study of ET-COVID-19

Acute ischemic stroke and large vessel occlusion can be concurrent with the coronavirus disease 2019 (COVID-19) infection. Outcomes after mechanical thrombectomy (MT) for large vessel occlusion in patients with COVID-19 are substantially unknown. Our aim was to study early outcomes after MT in patients with COVID-19

European Multicenter Study of ET-COVID-19

International audienceBackground and Purpose: Acute ischemic stroke and large vessel occlusion can be concurrent with the coronavirus disease 2019 (COVID-19) infection. Outcomes after mechanical thrombectomy (MT) for large vessel occlusion in patients with COVID-19 are substantially unknown. Our aim was to study early outcomes after MT in patients with COVID-19. Methods: Multicenter, European, cohort study involving 34 stroke centers in France, Italy, Spain, and Belgium. Data were collected between March 1, 2020 and May 5, 2020. Consecutive laboratory-confirmed COVID-19 cases with large vessel occlusion, who were treated with MT, were included. Primary investigated outcome: 30-day mortality. Secondary outcomes: early neurological improvement (National Institutes of Health Stroke Scale improvement ≥8 points or 24 hours National Institutes of Health Stroke Scale 0–1), successful reperfusion (modified Thrombolysis in Cerebral Infarction grade ≥2b), and symptomatic intracranial hemorrhage. Results: We evaluated 93 patients with COVID-19 with large vessel occlusion who underwent MT (median age, 71 years [interquartile range, 59–79]; 63 men [67.7%]). Median pretreatment National Institutes of Health Stroke Scale and Alberta Stroke Program Early CT Score were 17 (interquartile range, 11–21) and 8 (interquartile range, 7–9), respectively. Anterior circulation acute ischemic stroke represented 93.5% of cases. The rate modified Thrombolysis in Cerebral Infarction 2b to 3 was 79.6% (74 patients [95% CI, 71.3–87.8]). Thirty-day mortality was 29% (27 patients [95% CI, 20–39.4]). Early neurological improvement was 19.5% (17 patients [95% CI, 11.8–29.5]), and symptomatic intracranial hemorrhage was 5.4% (5 patients [95% CI, 1.7–12.1]). Patients who died at 30 days exhibited significantly lower lymphocyte count, higher levels of aspartate, and LDH (lactate dehydrogenase). After adjustment for age, initial National Institutes of Health Stroke Scale, Alberta Stroke Program Early CT Score, and successful reperfusion, these biological markers remained associated with increased odds of 30-day mortality (adjusted odds ratio of 2.70 [95% CI, 1.21–5.98] per SD-log decrease in lymphocyte count, 2.66 [95% CI, 1.22–5.77] per SD-log increase in aspartate, and 4.30 [95% CI, 1.43–12.91] per SD-log increase in LDH). Conclusions: The 29% rate of 30-day mortality after MT among patients with COVID-19 is not negligible. Abnormalities of lymphocyte count, LDH and aspartate may depict a patient’s profiles with poorer outcomes after MT. Registration: URL: https://www.clinicaltrials.gov . Unique identifier: NCT04406090
