Infección por dengue sin signos de alarma en un niño con cardiopatía chagásica crónica

Se presenta el caso de un preescolar en que se diagnosticó una cardiomiopatía chagásica crónica posterior a una infección aguda por virus dengue. El niño, residente de un área endémica para enfermedad de Chagas, debutó con insuficiencia cardíaca que mejoró con el tratamiento de soporte y tras la resolución completa de la arbovirosis, persistieron los cambios de cardiomiopatía crónica. Esta evidencia de alteración estructural miocárdica se atribuyó a la cardiomiopatía chagásica de base previamente subclínica. La coexistencia de enfermedades infecciosas en el trópico representa un reto diagnóstico, situación a la que se agregan problemas socioeconómicos como la pobreza y falta de acceso a servicios sanitarios básicos.

A case is reported of a chronic chagasic cardiomyopathy in a two-years old child who was diagnosed after an acute dengue virus infection. The patient residing in an endemic area for Chagas disease, debuted with heart failure that improved with support treatment and after the complete resolution of the arbovirus, the changes of chronic cardiomyopathy persisted. The myocardial structural alteration was attributed to subclinical chagasic cardiomyopathy. The coexistence of infectious diseases in the tropics represents a diagnostic challenge, a situation to which are added problems such as poverty and lack of access to basic health services.

Esquistossomose e o Coração - Em Nome das Doenças Tropicais Negligenciadas e Outras Doenças Infecciosas que Afetam o Coração (Projeto NET-Heart) / Schistosomiasis & Heart - On Behalf of the Neglected Tropical Diseases and other Infectious Diseases affecting the Heart (the NET-Heart Project)

Resumo Fundamento A esquistossomose é uma doença tropical negligenciada que pode levar a complicações cardiovasculares. No entanto, o envolvimento cardiovascular na esquistossomose ainda precisa ser totalmente elucidado, devido ao número limitado de casos e ausência de evidência confiável, uma vez que a doença ocorre tipicamente em locais sem infraestrutura adequada para uma coleta de dados robusta. Objetivo Esta revisão sistemática teve como objetivo avaliar as implicações cardiovasculares da esquistossomose, incluindo no diagnóstico e tratamento, e propor um algoritmo para rastrear as manifestações cardiovasculares. Métodos Foi realizada uma revisão sistemática nos bancos de dados MEDLINE/PubMed e LILACS, com busca por artigos sobre o comprometimento cardiovascular na esquistossomose. Resultados Trinta e três artigos foram considerados para esta revisão: seis artigos de revisão, uma revisão sistemática, um ensaio clínico, 14 estudos observacionais, sete relatos de casos, e quatro séries de casos. O comprometimento cardiovascular inclui um amplo espectro de condições clínicas, tais como isquemia do miocárdio, disfunção ventricular, miocardite, hipertensão arterial pulmonar, e pericardite. Conclusões As complicações cardíacas da esquistossomose podem causar incapacidade em longo prazo e morte. O monitoramento clínico, exame físico, eletrocardiograma precoce, e ecocardiograma devem ser considerados como medidas chave para detectar o envolvimento cardiovascular. Dada a ausência de um tratamento eficaz das complicações, são necessários saneamento e educação nas áreas endêmicas para a eliminação desse problema de saúde mundial.

Abstract Background Schistosomiasis is a Neglected Tropical Disease which may lead to cardiovascular (CV) complications. However, the CV involvement in schistosomiasis has yet to be fully elucidated due to the limited number of cases and lack of reliable evidence, as schistosomiasis typically occurs in locations without adequate infrastructure for robust data collection. Objective This systematic review aims to assess cardiovascular implications of schistosomiasis, including in the diagnosis and treatment, and propose an algorithm for screening of CV manifestations. Methods A systematic review was performed in the MEDLINE/PubMed and LILACS databases of articles on the CV involvement in schistosomiasis. Results Thirty-three records were considered for this review: six review articles, one systematic review, one clinical trial, 14 observational studies, seven case reports, and four cases series. CV involvement includes a wide spectrum of clinical conditions, such as myocardial ischemia, ventricular dysfunction, myocarditis, pulmonary arterial hypertension, and pericarditis. Conclusions Cardiac complications of schistosomiasis may cause long-term disability and death. Clinical monitoring, physical examination, early electrocardiogram, and echocardiogram should be considered as key measures to detect CV involvement. Due to the lack of effective treatment of complications, sanitation and education in endemic areas are necessary for the elimination of this global health problem.

Etiology and outcome of febrile children coming from the tropics.

INTRODUCTION: International travelers have grown significantly over last years, as well as imported diseases from tropical areas. Information in pediatric population is scarce. We describe demographic and clinical characteristics of febrile children coming from the tropics. METHODS: Retrospective review of patients under 18 years old, presenting at a tertiary hospital and surrounding primary health care centers between July 2002 and July 2018 with a stay in a tropical region during the previous year. Patients were selected from microbiological charts of thick smears for malaria or dengue serologies. RESULTS: 188 patients were studied: 52.7% were born in Spain with a median age of 3.0 years old (IQR 1.5-8.0). Main regions of stay were Sub-Saharan Africa (54.8%) and Latin America (29.8%), mostly for visiting their friends and relatives (56.3%), followed by recent arrival migrants (32.4%). Only 34% of travelers attended pre-travel consultation. More than 80% of these febrile children attended directly the Emergency Room. The most frequent diagnoses were febrile syndrome without source (56.4%), respiratory condition (15.4%) and acute diarrhea (11.7%). Around a half (52.1%) were managed as outpatients, but 46.2% were hospitalized and 7.4% were admitted to Intensive Care Unit. No specific diagnosis was achieved in 24% of cases. However, 29.7% were diagnosed with malaria. CONCLUSION: Children with fever coming from tropical areas were at risk of severe infectious diseases. Malaria was diagnosed in one out of four and 7% required admission in PICU. This information emphasizes the need of reinforcing training about tropical diseases among first line physicians.

Introducción: Los viajes internacionales han aumentado en los últimos años, así como las enfermedades importadas. Los datos en edad pediátrica son escasos. El objetivo de este estudio es describir las características clínico-epidemiológicas del niño con fiebre que viene del trópico. Métodos: Revisión retrospectiva de pacientes menores de 18 años que, tras una estancia en zona tropical en el último año, acuden con fiebre a un hospital terciario y centros de salud de área entre julio de 2002 y julio de 2018. Se seleccionaron a través de los registros de gotas gruesas o serologías de dengue. Resultados: Se incluyeron 188 pacientes. El 52,7% habían nacido en España, con edad mediana de 3 años (RIC 1,5-8,0). Las regiones de procedencia del viaje fueron África Sub-Sahariana (54,8%) y Latinoamérica (29,8%). Los motivos principales fueron visitar a allegados (56,3%), seguidos de inmigrantes de llegada reciente (32,4%). Solo el 34% de los viajeros habían realizado consulta pre-viaje. Más del 80% acudieron directamente a Urgencias. Los diagnósticos más frecuentes fueron síndrome febril sin focalidad (56,4%), enfermedad respiratoria (15,4%) y diarrea aguda (11,7%). La mitad (52,1%) fueron dados de alta, pero 46,2% fueron ingresados, y el 7,4% requirió Cuidados Intensivos. No se halló una etiología específica en el 24% de los casos. Sin embargo, el 29,7% tuvieron malaria. Conclusión: El síndrome febril en un niño procedente del trópico puede implicar enfermedades graves. Uno de cada cuatro tuvo malaria, y el 7% requirió cuidados intensivos. Por ello, es necesario reforzar la formación en enfermedades tropicales en los médicos de primera línea.(AU)

Virus Mayaro, un alphavirus olvidado en Colombia: posible efecto sobre la salud pública / Mayaro virus, an alphavirus forgotten in Colombia: possible effect on public health

Sobre el Mayaro virus poco se conoce sobre su transmisión y patogénesis. Se sabe que habita en diferentes zonas del hemisferio occidental y que es transmitido por los Aedes aegypti y albopictus (Diptera: Culicidae). Ya se han investigado escenarios donde su circulación puede superponerse y generar infecciones mixtas, y por ello ha ganado importancia en la salud pública, puesto que puede ocasionar alto riesgo de brotes con manifestaciones clínicas graves similares a la de los virus Zika, Chikungunya y el Dengue países como Trinidad, Brasil, México, Venezuela, Honduras, Salvador, Costa Rica, Panamá, Perú, Argentina, Surinam, Guyana, Venezuela, Ecuador y Bolivia. Colombia está expectante de una aparición concomitante junto con ZIKV y CHIKV. Se realizó una búsqueda exhaustiva en PubMed, Science Direct, Clinical Key y Ebsco sobre el Mayaro virus, epidemiología, su estructura molecular, ciclo de transmisión, sintomatología clínica, métodos diagnósticos, factores de riesgo, control y prevención, así como tratamiento actual, para conocer un panorama más amplio sobre su problemática..(Au)

About Mayaro virus, there is currently little knowledge of its transmission and pathogenesis. It is known to inhabit different areas of the Western Hemisphere and is transmitted by the Aedes aegypti and albopictus (Diptera: Culicidae). Numerous authors have focused their research given coexistence in scenarios where the circulations of all these viruses can somehow overlap and generate mixed infections. This agent has been gaining prominence at the public health level, due to the possibility of causing high risk of outbreaks with serious clinical manifestations similar to that of Zika viruses, Chikungunya virus and Dengue, in several countries, such as Trinidad, Brazil, Mexico, Venezuela, Honduras, Salvador, Costa Rica, Panama, Peru, Argentina, Suriname, Guyana, Venezuela, Ecuador and Bolivia. Colombia is looking forward to a concomitant onset in the near future along with ZIKV and CHIKV. Taking into account the above, a thorough search was carried out of the existing literature, on Mayaro virus, its molecular structure, transmission cycle, clinical symptomatology, diagnostic methods, risk factors, control and prevention, as well as treatment, to learn a broader picture of the problem that lurks. All this, through search engines like PubMed, Science Direct, Clinical Key and Ebsco..(Au)

Women made visible: a different perspective on the history of the Institute of Tropical Medicine in Portugal, 1943-1966 / Mulheres visíveis: uma perspectiva diferente na história do Instituto de Medicina Tropical em Portugal, 1943-1966

Abstract This work focuses on the scientific research conducted by women at Portugal's Institute of Tropical Medicine between 1943 and 1966. The Institute's scientific journal documents the participation of women in tropical medicine during this period. Their publications addressed a variety of subjects and resulted from research carried out in the metropolis as well as Portugal's overseas colonies. Most of the articles written by these women were are co-authored by their male colleagues, reflecting the incorporation of female researchers into scientific networks already established by men. This work in progress provides a starting point to lend visibility to a group of scientific actors who are practically absent from the historiography of tropical medicine.

Resumo O foco deste trabalho é a pesquisa científica realizada por mulheres no Instituto de Medicina Tropical, em Portugal, entre 1943 e 1966. O periódico científico do Instituto documenta a participação das mulheres na medicina tropical nesse período. Suas publicações abordavam uma diversidade de temas e resultaram de pesquisas realizadas na metrópole, bem como nas colônias ultramarinas de Portugal. A maioria dos artigos escritos por mulheres contava com a coautoria de seus colegas homens, refletindo a incorporação de pesquisadoras às redes científicas já estabelecidas por homens. Este trabalho em andamento representa um ponto de partida para dar visibilidade a um grupo de atores científicos que está praticamente ausente da historiografia da medicina tropical.

Critical care medicine in the French Territories in the Americas: Current situation and prospects / La medicina intensiva en los territorios franceses de la Región de las Américas: situación actual y perspectivas / Medicina intensiva nos territórios ultramarinos franceses nas Américas: situação atual e perspectivas

ABSTRACT Hospitals in the French Territories in the Americas (FTA) work according to international and French standards. This paper aims to describe different aspects of critical care in the FTA. For this, we reviewed official information about population size and intensive care unit (ICU) bed capacity in the FTA and literature on FTA ICU specificities. Persons living in or visiting the FTA are exposed to specific risks, mainly severe road traffic injuries, envenoming, stab or ballistic wounds, and emergent tropical infectious diseases. These diseases may require specific knowledge and critical care management. However, there are not enough ICU beds in the FTA. Indeed, there are 7.2 ICU beds/100 000 population in Guadeloupe, 7.2 in Martinique, and 4.5 in French Guiana. In addition, seriously ill patients in remote areas regularly have to be transferred, most often by helicopter, resulting in a delay in admission to intensive care. The COVID-19 crisis has shown that the health care system in the FTA is unready to face such an epidemic and that intensive care bed capacity must be increased. In conclusion, the critical care sector in the FTA requires upgrading of infrastructure, human resources, and equipment as well as enhancement of multidisciplinary care. Also needed are promotion of training, research, and regional and international medical and scientific cooperation.

RESUMEN Los hospitales en los territorios franceses de la Región de las Américas funcionan según las normas francesas e internacionales. El objetivo de este artículo es describir distintos aspectos de los cuidados intensivos en los territorios franceses. Para ello, hemos revisado los datos oficiales sobre el tamaño de la población y el número de camas de las unidades de cuidados intensivos (UCI), así como la bibliografía sobre algunos aspectos específicos de las UCI, en los territorios franceses. Las personas que viven en los territorios franceses, o que están de visita en ellos, están expuestas a riesgos específicos: principalmente traumatismos graves causados por el tránsito, envenenamiento por mordeduras, heridas de bala o por apuñalamiento, y enfermedades infecciosas tropicales emergentes. La atención de estos traumatismos y enfermedades puede requerir conocimientos específicos y cuidados intensivos. Sin embargo, no hay suficientes camas de UCI en los territorios franceses. De hecho, hay 7,2 camas de UCI por 100 000 habitantes en Guadalupe, 7,2 en Martinica y 4,5 en Guayana Francesa. Además, los pacientes gravemente enfermos que viven en zonas remotas a menudo tienen que ser trasladados, normalmente por helicóptero, lo que retrasa su ingreso en la unidad de cuidados intensivos. La crisis de la COVID-19 ha puesto de manifiesto que el sistema de atención de salud en los territorios franceses no está preparado para enfrentarse a una epidemia de estas dimensiones y que debe aumentarse la capacidad hospitalaria de las unidades de cuidados intensivos. En conclusión, el sector de los cuidados intensivos en los territorios franceses tiene que mejorar su infraestructura, recursos humanos y equipamiento, así como perfeccionar la atención multidisciplinaria. También es necesario promover la capacitación, la investigación y la cooperación médica y científica, tanto regional como internacional.

RESUMO Os hospitais nos territórios ultramarinos franceses nas Américas funcionam segundo os padrões franceses e internacionais. O objetivo deste artigo é descrever os diversos aspectos da atenção intensiva nesta região. Analisamos os dados oficiais relativos ao tamanho da população e ao número de leitos de unidade de terapia intensiva (UTI) nestes territórios junto com uma revisão da literatura científica sobre as características particulares destes centros de terapia intensiva. Os residentes locais ou visitantes dos territórios ultramarinos franceses nas Américas são expostos a riscos específicos, sobretudo acidentes de trânsito graves, envenenamentos por animais peçonhentos, ferimentos por armas brancas ou armas de fogo e doenças infecciosas tropicais emergentes que requerem conhecimento especializado e atenção intensiva. Porém, não há leitos suficientes de UTI nos territórios ultramarinos franceses nas Américas: são 7,2 leitos de UTI por 100.000 habitantes em Guadalupe, 7,2 na Martinica e 4,5 na Guiana Francesa. Ademais, em áreas remotas, os pacientes em estado crítico frequentemente precisam ser transferidos por helicóptero, o que causa demora na internação em UTI. A crise da COVID-19 demonstra o despreparo do sistema de saúde para enfrentar a pandemia e a necessidade de aumentar o número de leitos de UTI nestes territórios. Em conclusão, é imprescindível modernizar a infraestrutura e os equipamentos, capacitar melhor os recursos humanos e melhorar a atenção multidisciplinar. Incentivar a formação profissional, pesquisa e cooperação médico-científica regional e mundial é também fundamental.

Etiology and outcome of febrile children coming from the tropics.

INTRODUCTION: International travelers have grown significantly over last years, as well as imported diseases from tropical areas. Information in pediatric population is scarce. We describe demographic and clinical characteristics of febrile children coming from the tropics. METHODS: Retrospective review of patients under 18 years old, presenting at a tertiary hospital and surrounding primary health care centers between July 2002 and July 2018 with a stay in a tropical region during the previous year. Patients were selected from microbiological charts of thick smears for malaria or dengue serologies. RESULTS: 188 patients were studied: 52.7% were born in Spain with a median age of 3.0 years old (IQR 1.5-8.0). Main regions of stay were Sub-Saharan Africa (54.8%) and Latin America (29.8%), mostly for visiting their friends and relatives (56.3%), followed by recent arrival migrants (32.4%). Only 34% of travelers attended pre-travel consultation. More than 80% of these febrile children attended directly the Emergency Room. The most frequent diagnoses were febrile syndrome without source (56.4%), respiratory condition (15.4%) and acute diarrhea (11.7%). Around a half (52.1%) were managed as outpatients, but 46.2% were hospitalized and 7.4% were admitted to Intensive Care Unit. No specific diagnosis was achieved in 24% of cases. However, 29.7% were diagnosed with malaria. CONCLUSION: Children with fever coming from tropical areas were at risk of severe infectious diseases. Malaria was diagnosed in one out of four and 7% required admission in PICU. This information emphasizes the need of reinforcing training about tropical diseases among first line physicians.

"Hipnóticos" na metrópole: africanos no Hospital Colonial de Lisboa nas primeiras décadas do século XX / "Hypnotics" in the metropolis: Africans in the Colonial Hospital of Lisbon during the early twentieth century

Resumo No início do século XX, alguns médicos portugueses foram à África estudar a chamada doença do sono. Entre eles estava Ayres Kopke, membro da primeira missão médica à África Ocidental Portuguesa. De regresso a Lisboa, o professor da Escola de Medicina Tropical continuou suas pesquisas, inclusive por meio da observação de doentes trazidos para a metrópole. Desde 1903, as repartições de saúde nas colônias estavam incumbidas de enviar doentes com determinadas patologias exóticas para o Hospital Colonial de Lisboa. Com base em documentos desse hospital, incluindo fotografias dos doentes, então chamados de hipnóticos, o artigo aborda a importância das experiências com humanos na metrópole para o avanço da medicina tropical durante o colonialismo.

Abstract At the start of the twentieth century, some Portuguese physicians traveled to Africa to study sleeping sickness (African trypanosomiasis). One was Ayres Kopke, a member of the first medical mission to Portuguese West Africa and professor at the School of Tropical Medicine. After returning to Lisbon, Kopke continued his research, which included observation of patients brought to the metropolis. Starting in 1903, health departments in the colonies were responsible for sending patients with certain exotic diseases to the Colonial Hospital of Lisbon. Based on documents from this hospital including photographs of patients (who at that time were called "hypnotics"), this article discusses the importance of human experiments in Lisbon for advances in tropical medicine during the colonial period.

Ardentes trópicos: febres e saúde pública no Brasil joanino / The scorching tropics: fevers and public health in Brazil during the Joanine period, 1808-1821

Resumo Com exceção da febre amarela, as febres ainda foram pouco exploradas pela historiografia da saúde brasileira. No século XIX, contudo, sua presença na vida social era quase incontornável, atingindo enormes parcelas da população. Suas vítimas padeciam de uma grande variedade de sintomas em que a identificação e a terapêutica eram objeto de intensos debates nos círculos médicos. A intelectualidade luso-brasileira, atenta tanto aos debates médicos europeus quanto a experiências clínicas, esforçou-se para fornecer respostas na forma de intensa produção impressa; no entanto, as manifestações febris encontradas nos trópicos representavam um desafio extra à sua formação europeia, forçando-a a conjugar experiências adquiridas em partes distintas do Império na constituição de saberes específicos sobre as febres tropicais.

Abstract Although fevers (with the exception of yellow fever) have not yet been fully explored by the historiography of Brazilian health, they were almost inevitable in nineteenth-century Brazilian society, affecting huge portions of the population. Their victims suffered from a wide variety of symptoms, and identification and treatment of these symptoms were the object of intense debates in medical circles. The Luso-Brazilian intelligentsia considered European medical debates as well as their own clinical experiences and attempted to provide answers in a flurry of publications. Even so, the manifestations of fever in the tropics presented a challenge that lay beyond their European training, forcing them to combine experiences acquired in different parts of the Empire to comprise specific knowledge on tropical fevers.

Breve reseña de vida y contribución del médico parasitólogo peruano César Gabriel Náquira Velarde / Brief review about the life and contribution of the peruvian parasitologist Cesar Gabriel Naquira Velarde

RESUMEN Las instituciones científicas y sus logros se construyen a partir de las personas y sus historias. En este caso, el Dr. César Náquira Velarde es una personalidad destacada en la salud pública del Perú, a la que contribuyó hasta días antes de su partida a los 85 años de edad. El Dr. Náquira participó activamente en la fundación del Instituto de Medicina Tropical Daniel A. Carrión de la Universidad Nacional Mayor de San Marcos desde donde −a través de la investigación y docencia− ha formado médicos y especialistas en el campo de la parasitología y medicina tropical. Sin embargo, su mayor contribución y aporte fue en el estudio de la enfermedad de Chagas. También se desempeñó como funcionario público y decisor, pues fue jefe del Instituto Nacional de Salud y permanente asesor técnico del Ministerio de Salud del Perú, en los temas de su especialidad. Destacamos su rol como maestro para muchas generaciones de médicos y su autoridad como experto en el campo de la parasitología médica.

ABSTRACT Scientific institutions and their achievements are built on people and their stories. In this case, Dr. César Náquira Velarde constitutes a prominent figure in Peru's public health, to which he contributed until days before his departure at 85 years of age. Dr. Náquira actively participated in the founding of the Daniel A. Carrión Institute of Tropical Medicine of the National University of San Marcos from where - through re search and teaching - he has trained doctors and specialists in the field of parasitology and tropical medici ne. However, his greatest contribution was in the study of Chagas disease. He also served as a public official and decision maker, as he was head of the National Institute of Health of Peru and permanent technical advisor of the Ministry of Health of Peru, in the areas of his specialty. We highlight his role as a teacher for many generations of doctors and his authority as an expert in the field of medical parasitology.

O Instituto de Medicina Tropical de São Paulo: marcas de sua criação, 1940-1959 / The Institute for Tropical Medicine of São Paulo: characteristics of its creation, 1940-1959 / El Instituto de Medicina Tropical de São Paulo: marcas de su creación, 1940-1959

Este artigo foi escrito a partir de um trabalho de perscrutação a jornais, relatórios e textos memorialísticos e objetiva oferecer um contributo historiográfico sobre a criação do Instituto de Medicina Tropical de São Paulo, sancionada em janeiro de 1959 após uma movimentação institucional liderada pelo professor Carlos da Silva Lacaz, seu primeiro diretor. Procura-se destacar aqui dois importantes eixos que contribuíram para a decisão em prover a capital paulista de um Instituto de Medicina Tropical: em primeiro lugar, a internacionalização da Medicina Tropical brasileira, nomeadamente sua relação com tropicalistas portugueses, consubstanciada com a ida de brasileiros - em especial, paulistas - aos institutos de Medicina Tropical na Europa e, em segundo lugar, a presença de endemias rurais no estado de São Paulo (Brasil), que começavam a tornar-se visíveis na capital em decorrência dos movimentos migratórios em direção à cidade.(AU)

This article was based on an examination of newspapers, reports, and memorial texts. It aims at offering a historiographical contribution about the creation of the Institute for Tropical Medicine (IMT, Instituto de Medicina Tropical), approved in January 1959 after an institutional movement led by Prof. Carlos da Silva Lacaz, who was also its first director. The objective is to highlight important factors that contributed to the decision of creating an institute of Tropical Medicine in the Brazilian city of São Paulo, capital of the state of São Paulo. The first of them was to internationalize the Brazilian Tropical Medicine, namely its relationship with Portuguese tropicalists that was consubstantiated with the migration of Brazilians, particularly from the city of São Paulo, to European institutes of Tropical Medicine. The presence of rural endemic diseases in the state, which were becoming increasingly visible in the capital due to migratory movements to the big city, also contributed to its creation.(AU)

Se busca destacar aquí dos ejes importantes que contribuyeron para la decisión de proporcionar a la capital del Estado de São Paulo un instituto de Medicina Tropical: en primer lugar, la internacionalización de la Medicina Tropical brasileña, principalmente su relación con tropicalistas portugueses, consubstanciada con la ida de brasileños, en especial del estado de São Paulo, a los institutos de medicina tropical en Europa y, en segundo lugar, la presencia de endemias rurales en el Estado de São Paulo (Brasil) que comenzaban a ser visibles en la capital debido a los movimientos migratorios hacia la ciudad.(AU)

El Instituto de Medicina Tropical "Pedro Kourí", antecedentes y desafíos en su 80 Aniversario: antecedents and challenges on its 80th anniversary

Se hace una descripción del Instituto de Medicina Tropical "Pedro Kourí", desde su fundación en el año 1937 hasta nuestros días. Es destacado el cambio producido en 1979 cuando el instituto se revitaliza y amplía su perfil a todas las enfermedades transmisibles (parasitarias, bacterianas, virales y micóticas), desde la investigación, la epidemiología, la clínica, la entomología y los laboratorios. Al final de la comunicación se destacan los resultados científicos nacionales e internacionales más relevantes obtenidos por la institución.

A description is provided of Pedro Kourí Tropical Medicine Institute from its founding in the year 1937 to the present. Reference is made to the changes undergone by the Institute in 1979, when it was revitalized and broadened its profile to cover all communicable diseases (parasitic, bacterial, viral and mycotic) from a research, epidemiological, clinical, entomological and laboratory perspective. At the end of the communication a list is provided of the most relevant national and international scientific results obtained by the institution.

Estratégia para a recuperação de informação científica sobre as doenças tropicais negligenciadas: análise comparativa da Scopus, Pubmed e Web of Science / Estrategia para la recuperación de la información científica sobre enfermedades tropicales desatendidas: análisis comparativo de Scopus, PubMed y Web of Science / Strategy for information retrieval of scientific on neglected tropical diseases: comparative analysis of Scopus, PubMed and Web of Science

Objetiva desenvolver um percurso metodológico para recuperar informações científicas sobre as Doenças Tropicais Negligenciadas (DTN) em bases de dados internacionais (Scopus, Web of Science e PubMed). Os procedimentos metodológicos desta pesquisa foram: a) identificação das principais doenças tropicais segundo a Organização Mundial da Saúde; b) padronização dos nomes das doenças a partir dos Descritores em Ciências da Saúde da Biblioteca Virtual de Saúde (DeCS/BVS); c) construção de duas listas: uma com os termos controlados associados a operadores booleanos, e outra com os termos não controlados, também estruturada com operadores booleanos; d) busca de informações nas principais bases de dados anteriormente citadas de maneira controlada e não controlada; e) comparação dos resultados obtidos entre a busca controlada e não controlada; f) construção de fluxo metodológico para fins de replicação. Percebeu-se que o uso da busca controlada aumentou a revocação do processo de recuperação da informação, especificamente, a Base Scopus apresentou um aumento mais significativo na recuperação de resultados (11,28 %). A PubMed teve um incremento na revocação de 8,92 % e a Web of Science de 2,64 %. Ademais, propõe-se neste trabalho um fluxo para a recuperação da informação nas referidas bases, que sirva para os pesquisadores neste tema, pois entende-se que o alto grau de variabilidade das palavras e a dispersão na representação do tema nas bases constitui-se no importante impeditivo para a recuperação de informações(AU)

El objetivo de esta investigación fue desarrollar una metodología para recuperar informaciones científicas sobre las enfermedades tropicales desatendidas, en bases de datos internacionales (Scopus, Web of Science y PubMed). Los procedimientos metodológicos de esta investigación fueron: a) identificación de las principales enfermedades tropicales según la Organización Mundial de la Salud; b) estandarización de los nombres de las enfermedades a partir de los Descriptores en Ciencias de la Salud de la Biblioteca Virtual de Salud (DeCS/BVS); c) construcción de dos listas: una con los términos controlados asociados a operadores booleanos, y otra con los términos no controlados, también estructurada con operadores booleanos; d) búsqueda de informaciones en las principales bases de datos anteriormente citadas de manera controlada y no controlada; e) comparación de los resultados obtenidos entre la búsqueda controlada y no controlada; f) construcción de flujo metodológico para fines de replicación. Se percibió que el uso de la búsqueda controlada aumentó la revocación del proceso de recuperación de la información. Específicamente la Base Scopus presentó un aumento más significativo en los resultados (11,28 %). PubMed tuvo un incremento en la revocación del 8,92 % y la Web of Science del 2,64 %. Además, se propone en este trabajo un flujo para la recuperación de la información en las referidas bases, que sirva para los investigadores en este tema, pues se entiende que el alto grado de variabilidad de las palabras y la dispersión en la representación del tema en las bases se constituyen en importante impedimento para la recuperación de informaciones(AU)

It aims to develop a methodological pathway for the retrieval of scientific information on neglected tropical diseases in international databases (Scopus, Web of Science and PubMed). The methodological procedures performed in this work were: a) identification of the main tropical diseases according to the World Health Organization; b) conversion of the names of the diseases in standardized terms from the Descriptors in Health Sciences of the Virtual Health Library (DeCS), c) the construction of two lists: one with the standard terms associated with Boolean operators, and the other with the nonstandard terms; d) search for information in the main databases previously mentioned in a standardized and non-standardized way; e) comparison of the results obtained between standardized and non-standardized search; f) methodological flow construction for replication purposes. As a main result it was observed that the use of the standardized search increased the recall of the information retrieval process, and Scopus was the basis that presented a more significant increase in the retrieval of results (11.28 %). PubMed had an increase in recall of 8.92 % and Web of Science of 2.64 %. In addition, it is proposed in this work a flow for the retrieval of the information in the mentioned bases, that can be useful to all the researchers who wish to obtain scientific information on this subject, since it is understood that the high degree of variability of the words and the dispersion in the representation of the theme in the bases constitutes the important impediment for the information retrieval(AU)
