Síndrome de takotsubo secundario a trastorno emocional adaptativo / Takotsubo syndrome secondary to adaptative emotional disorder

Introducción: El síndrome de takotsubo o cardiomiopatía por stress, se caracteriza por una disfunción sistólica regional transitoria, principalmente del ventrículo izquierdo que simula un infarto agudo de miocardio, pero en ausencia de evidencia angiográfica de enfermedad arterial coronaria obstructiva o rotura aguda de placa. Es la causa del 1-2 % de todos los síndromes coronarios agudos, se requiere de un diagnóstico oportuno y un tratamiento adecuado para evitar la morbimortalidad por esta patología. Objetivo: destacar la importancia de tener en cuenta el síndrome de takotsubo o cardiomiopatía por estrés como diagnóstico diferencial de los pacientes con dolor torácico según la historia clínica y los desencadenantes del dolor. Presentación de caso: Paciente de 50 años de edad con dolor torácico de características típicas posterior a episodio emocional; reporte de electrocardiograma inicial isquemia anterolateral con troponina positiva y falla cardiaca sistólica, angiografía sin alteración en los vasos coronarios, se diagnosticó síndrome de takotsubo. Conclusión: Es importante considerar el síndrome de takotsubo en el diagnóstico diferencial de los pacientes con dolor torácico, evaluando las circunstancias por las cuales se origina el dolor, ya que requiere un manejo médico multidisciplinario.

Introduction: Takotsubo syndrome or stress cardiomyopathy is characterized by a transient regional systolic dysfunction, mainly of the left ventricle that simulates an acute myocardial infarction, but in the absence of angiographic evidence of obstructive coronary artery disease or acute plaque rupture. It is the cause of 1-2 % of all acute coronary syndromes, which requires a timely diagnosis and an adequate treatment to avoid morbidity and mortality from this pathology. Objective: to highlight the importance of taking into account takotsubo syndrome or stress cardiomyopathy as a differential diagnosis in patients with chest pain according to the clinical history and pain triggers. Case presentation: Fifty-year-old patient with typical chest pain after an emotional episode; the initial electrocardiogram reported anterolateral ischemia with positive troponin and systolic heart failure, and the angiography showed no alteration in the coronary vessels, concluding with the diagnosis of Takotsubo syndrome. Conclusion: It is important to consider takotsubo syndrome in the differential diagnosis of patients with chest pain, evaluating the circumstances by which the pain originates since it requires multidisciplinary medical management.

Síndrome hemofagocítico secundario a infección por virus del dengue / Hemophagocytic syndrome secondary to dengue virus infection

Introducción: El síndrome hemofagocítico se presenta como un cuadro clínico grave, provocado por una respuesta inadecuada del sistema inmunológico a un desencadenante infeccioso, neoplásico, reumatológico o metabólico, que origina una reacción inflamatoria no controlada; presenta una incidencia baja pero la letalidad sin el manejo adecuado es muy elevada. Objetivo: Destacar la importancia de diagnóstico oportuno del síndrome hemofagocítico en pacientes con dengue que presentan evolución tórpida. Presentación del caso: Paciente de 7 años de edad, con dengue grave dado por shock, hepatomegalia con elevación de transaminasas, con mala evolución clínica, quien cumple criterios de Síndrome hemofagocítico. Recibió manejo con inmunomoduladores con evolución satisfactoria. Conclusiones: Es importante considerar el Síndrome hemofagocítico como causa ante enfermedades con evolución tórpida a pesar de tener un manejo médico correcto(AU)

Introduction: Hemophagocytic syndrome is a severe clinical picture with an uncontrolled inflammatory reaction caused by an inadequate immune system response to an infectious, neoplastic, rheumatological, or metabolic trigger. The syndrome has low incidence but high fatality when the management is not adequate. Objective: To highlight the importance of a prompt diagnosis of hemophagocytic syndrome in patients with dengue who present a torpid evolution. Case presentation: Seven-year-old patient with severe dengue caused by shock, hepatomegaly with elevated transaminase levels and poor clinical evolution who meets hemophagocytic syndrome criteria. The patient had satisfactory progression after receiving immunomodulatory treatment. Conclusions: Hemophagocytic syndrome must be considered as a cause of pathologies in dengue patients with torpid evolution, even when correct medical management is made(AU)

Contributions of Latin American researchers in the understanding of the novel coronavirus outbreak: a literature review.

This article aimed to give the visibility of Latin American researchers' contributions to the comprehension of COVID-19; our method was a literature review. Currently, the world is facing a health and socioeconomic crisis caused by the novel coronavirus, SARS-CoV-2, and its disease COVID-19. Therefore, in less than 4 months, researchers have published a significant number of articles related to this novel virus. For instance, a search focused on the Scopus database on 10 April 2020, showed 1,224 documents published by authors with 1,797 affiliations from 80 countries. A total of 25.4%, 24.0% and 12.6% of these national affiliations were from China, Europe and the USA, respectively, making these regions leaders in COVID-19 research. In the case of Latin America, on 10 April 2020, we searched different databases, such as Scopus, PubMed and Web of Science, finding that the contribution of this region was 2.7 ± 0.6% of the total publications found. In other words, we found 153 publications related to COVID-19 with at least one Latin American researcher. We summarized and processed the information from these 153 publications, finding active participation in topics like medical, social and environmental considerations, bioinformatics and epidemiology.
