RESUMO

Temor y ambivalencia son aspectos centrales en la matriz sociocultural relacionada con la muerte encefálica. Para el médico que debe evaluar pacientes y certificar el diagnóstico de muerte encefálica es crucial contar con una sólida comprensión de la fisiopatología, los criterios diagnósticos y de los exámenes complementarios. La existencia de un marco legal coherente y completo para el diagnóstico de muerte encefálica, independiente de la potencial donación de órganos, es ciertamente crucial para el médico. La relevancia que tiene en este sentido el fallo del Tribunal Constitucional de Chile del 13 de agosto de 1995 se analiza en profundidad.


Fear and ambivalence are key aspects of the sociocultural frame related to brain death. For those physicians who have to evaluate patients and certify the diagnosis of brain death a sound comprehension of the physiopathology, the clinical features and the complementary diagnostic test is crucial. The existence of a comprehensive and coherent legal regulation for the diagnosis of brain death, clearly independent of the potential of organ donation is also crucial. The relevance of the judgment given in 1995 by the Chilean Constitutional Court to provide these consistency is pointed out.

RESUMO

Stroke is a major public health problem in Chile, with an incidence similar to that of many industrialized nations, it accounts for 10% of all deaths and ranks 5th in number of healthy years of life lost to a disease. Organized inpatient care for stroke patients has been shown in systematic reviews of randomized clinical trials to be effective in preventing death, disability and institutional care, without increasing length of stay compared to usual care. Organized stroke unit care is provided by multidisciplinary teams that exclusively manage stroke patients in a dedicated ward (stroke ward) of which there are various possible models; acute stroke units which accept patients acutely but discharge early (usually within 7 days). This could include an "intensive" model of care with continuous monitoring and high nurse staffing levels; comprehensive (i.e. combined acute and rehabilitation) stroke units which accept patients acutely but also provide rehabilitation for at least several weeks if necessary. The way in which stroke units affect outcome is through reduction of complications of immobility and probably non specific neuroprotection. Stroke units should deliver high quality evidence based interventions to all eligible patients and should maintain high standards of care through staff training, guidelines and protocols, audit and quality assurance. Given that stroke is one of the fifty six health priorities in the health reform, inpatient stroke care should be delivered through stroke units organized in hospitals throughout Chile.

RESUMO

Glottic dysfunction is a frequent condition in patients with acute neurological diseases: the incidence in stroke patients is between 45 - 51 percent increasing mortality three times. The principal complication is aspiration, which demands the involvement of pulmonary physicians and neurologists. The purpose of this study is to evaluate wet voice, water swallow test and cervical auscultation as clinical predictors of aspiration using endoscopical observation as a gold standard. During a period of one year we have prospectively evaluated these tests in acute neurological patients hospitalized in an intensive care unit. Wet voice, 3 oz water swallow test and cervical auscultation demonstrated sensibilities of 66.7, 88.9 and 77.8 percent, with a respective specificity of 85.2, 59.3 and 77.8 percent. Positive predictive values were 60, 42.1 and 53.8 percent, with negative predictive values of 88.5, 94.1 and 91.3 percent respectively. These results support the utility of clinical aspiration screening as a simple and valuable technique that can be done at the bedside.


La disfunción glótica es una entidad prevalente en enfermos con patología neurológica aguda: compromete aproximadamente entre el 45 al 51 por ciento de los pacientes que padecen un ataque cerebrovascular, incrementando su mortalidad en una relación de 3/1. Su complicación principal es el síndrome aspirativo, que involucra diversas especialidades, entre ellas enfermedades respiratorias y neurología. El propósito de este estudio ha sido evaluar la fonación húmeda, el test del vaso de agua y la auscultación cervical como indicadores clínicos de aspiración frente a la certificación nasolaringoscópica, considerada patrón estándar de evaluación al lado de la cama del enfermo. Evaluamos prospectivamente durante un año a pacientes neurológicos agudos hospitalizados en una unidad de tratamiento intensivo. La fonación húmeda, el test del vaso de agua y la auscultación cervical demostraron sensibilidades de 66,7, 88,9 y 77,8 por ciento, con una especificidad respectiva de 85,2, 59,3 y 77,8 por ciento. Los valores predictivos positivo fueron de 60, 42,1 y 53,8 por ciento, con valores predictivos negativo de 88,5, 94,1 y 91,3 por ciento respectivamente. Nuestros resultados permiten afirmar que el monitoreo clínico de aspiración es un instrumento sencillo y valioso, que puede ser realizado al lado de la cama del enfermo.

RESUMO

En una paciente de 12 años de edad, aparentemente sana hasta los 9 años, con epilepsia progresiva, deterioro mental, acidosis láctica y déficit neurológicos que simulaban accidentes cerebrovasculares, la biopsia muscular demostró fibras rojas desflecadas y acúmulos de mitocondrias anormales, confirmando el diagnóstico de encefalomiopatía mitocondrial. Conviene pensar en este grupo de enfermedades en pacientes escolares con cefalea periódica, epilepsia mioclónica que responde mal al tratamiento, hipoacusia sensorioneural y deterioro mental. Las manifestaciones musculares pueden ser frecuentemente tardías
