RESUMO
Introducción: La enfermedad cerebrovascular (ECV) es una urgencia neurológica que en ocasiones se encuentra influenciada por los cambios del tiempo. La ECV isquémica es una emergencia médica con una ventana estrecha para su diagnóstico y tratamiento. El daño generado por esta enfermedad se estima mediante de la mortalidad, discapacidad e impacto social. Objetivo: Proponer un programa de capacitación basado en los efectos fisiopatológicos que provocan en los pacientes, cambios de tiempo y ritmo circadiano en el contexto de la adaptación al cambio climático. Método: Se desarrolló un estudio multietápico prospectivo en el Hospital Universitario Mártires del 9 de Abril del municipio Sagua la Grande entre los años 1993 a 2017. En la primera etapa se seleccionó un universo de 52 profesionales de la salud que atendieron a estos pacientes; en la segunda, 48 y en la tercera, 61. Resultados: El nivel de conocimiento del personal de salud en una primera etapa era inadecuado (78,85 %); en la tercera, este porcentaje disminuyó (14,75 %). Como resultado de la capacitación mejoraron los tiempos de atención a los pacientes con ECV a su llegada al hospital, y en la tercera, más del 50 % de los enfermos fueron atendidos antes de las seis horas de inicio de los síntomas. Conclusiones: La capacitación sobre ECV basada en los efectos fisiopatológicos que provocan en los pacientes el cambio climático y el ritmo circadiano disminuyó el tiempo de espera, y se asoció con una reducción de la morbilidad y la mortalidad, después de aplicar este programa.
Introduction: cerebrovascular disease (CVD) is a neurological emergency that is sometimes influenced by climate changes. Ischemic CVD is a medical emergency with a narrow window for diagnosis and treatment. The damage generated by this disease is estimated through mortality, disability and social impact. Objective: to propose a training program based on the pathophysiological effects in patients caused by changes in time and circadian rhythm in the context of adaptation to climate change. Methods: a multistage prospective study was conducted at "Mártires del 9 de Abril" University Hospital in Sagua la Grande municipality between 1993 and 2017. A universe of health professionals who cared for these patients was selected as follows: 52 in the first stage; 48 in the second stage, and 61 in the third ones. Results: the level of knowledge of health personnel in the first stage was inadequate (78.85%); this percentage decreased in the third stage (14.75%). Care times for CVD patients improved upon arrival at the hospital as a result of the training, as well as in the third ones, more than 50% of the patients were seen within six hours of the onset of symptoms. Conclusions: CVD training based on the pathophysiological effects of climate change and circadian rhythm on patients decreased waiting time, and was associated with reduced morbidity and mortality, after applying this program.

ABSTRACT Objective To analyze data from children who were previously healthy and presented with post-varicella arterial ischemic stroke upon arrival when admitted to the emergency room, with focus on the clinical/laboratory aspects, and neurocognitive performance after four-year follow-up. Methods Seven children presenting with arterial ischemic stroke after varicella were evaluated at pediatric emergency services in the city of São Paulo (SP), Brazil. Ischemic stroke was determined by magnetic resonance imaging/magnetic resonance angiography in a topography compatible with the areas supplied by the middle cerebral or internal carotid arteries. IgG-class antibodies against varicella zoster virus and varicella-zoster virus DNA by polymerase chain reaction in cerebrospinal fluid were tested. Patients with prothrombotic conditions were excluded. The Pediatric Stroke Outcome Measure was applied upon admission and 4-years after the stroke. Results All patients (age range: 1.3 to 4 years) included presented chickenpox 5.1 (±3.5) months before. All patients had analysis of anti-varicella-zoster-virus-IgG in cerebrospinal fluid, but only three (43%) had a positive result. Of the patients 43% had no vascular lesions identified in magnetic resonance angiography. All patients showed improvement in their sequela scores. After 4 years, five patients displayed good evolution in the Pediatric Stroke Outcome Measure, and only one patient presented with a score of 2 in the sensorimotor and cognition areas. No recurrence of arterial ischemic stroke was observed. Conclusion We reinforced the non-progressive course of post-varicella arterial ischemic stroke after 4-year follow-up. The presence of varicella-zoster-virus-DNA detected by polymerase chain reaction, and/or intrathecal IgG antibody against varicella zoster virus, and angiopathy location in magnetic resonance angiography were not determining for the diagnosis. Invasive tests, with low sensitivity, should be well considered in the diagnosis of post-varicella arterial ischemic stroke.
RESUMO
Moyamoya disease is a chronic neurovascular disease characterized by progressive bilateral stenosis of the internal carotid arteries with abnormal formation of new abnormal blood vessels whose blockage of blood flow causes a variety of clinical manifestations and complications associated with acute cerebrovascular events (ischemic or hemorrhagic), which may even be fatal. This article seeks to describe this entity, its incidence, prevalence, forms of presentation, therapeutic measures and prognosis through a clinical case report. (Acta Med Colomb 2020; 45. DOI:http://doi.org/10.36104/amc.2020.1424).
La enfermedad de Moyamoya es una enfermedad neurovascular crónica caracterizada por una estenosis progresiva bilateral de las arterias carótidas internas, con la formación anormal de nuevos vasos sanguíneos, cuyo bloqueo en flujo sanguíneo ocasiona variadas manifestaciones clínicas y complicaciones asociadas a eventos cerebrovasculares (isquémicos o hemorrágicos) agudos que pueden llegar a ser incluso mortales. El presente artículo pretende realizar una aproximación acerca de esta entidad, su incidencia, prevalencia, formas de presentación y medidas terapéuticas y pronostico mediante el reporte de un caso clínico.(Acta Med Colomb 2020; 45.
