ABSTRACT

Abstract Objectives: To detect RSV or other thirteen respiratory viruses as possible causer agent of bronchiolitis in infants. Method: This is an epidemiological analytical study, conducted using a nasopharyngeal aspirate of 173 hospitalized children younger than two years old with severe bronchiolitis in three hospitals in the Campinas Metropolitan Region (CMR) during 2013-14. The data was statically evaluated by Pearson's chi-squared test with statistical significance of 0.05 and 95% confidence level. Results: As expected, the most prevalent viruses detected were RSV A and B in 47% and 16% of the samples, respectively. However, almost a third of severe bronchiolitis cases there were no detection of RSV, and the viruses more commonly detected were rhinoviruses, which were identified in almost a quarter of all positive samples for at least a viral agent. Conclusions: Although nothing could be concluded from the disease severity and clinicalepidemiological data, the present study's results indicate that severe bronchiolitis is not always related to RSV infections in children younger than two years old, and the rhinoviruses were more prevalent in these cases. These findings reinforce the need to carry out a

ABSTRACT

ABSTRACT Some chronic respiratory diseases can cause hypoxemia and, in such cases, long-term home oxygen therapy (LTOT) is indicated as a treatment option primarily to improve patient quality of life and life expectancy. Home oxygen has been used for more than 70 years, and support for LTOT is based on two studies from the 1980s that demonstrated that oxygen use improves survival in patients with COPD. There is evidence that LTOT has other beneficial effects such as improved cognitive function, improved exercise capacity, and reduced hospitalizations. LTOT is indicated in other respiratory diseases that cause hypoxemia, on the basis of the same criteria as those used for COPD. There has been an increase in the use of LTOT, probably because of increased life expectancy and a higher prevalence of chronic respiratory diseases, as well as greater availability of LTOT in the health care system. The first Brazilian Thoracic Association consensus statement on LTOT was published in 2000. Twenty-two years later, we present this updated version. This document is a nonsystematic review of the literature, conducted by pulmonologists who evaluated scientific evidence and international guidelines on LTOT in the various diseases that cause hypoxemia and in specific situations (i.e., exercise, sleep, and air travel). These recommendations, produced with a view to clinical practice, contain several charts with information on indications for LTOT, oxygen sources, accessories, strategies for improved efficiency and effectiveness, and recommendations for the safe use of LTOT, as well as a LTOT prescribing model.


RESUMO Algumas doenças respiratórias crônicas podem evoluir com hipoxemia e, nessas situações, a oxigenoterapia domiciliar prolongada (ODP) está indicada como opção terapêutica com o objetivo principal de melhorar a qualidade e a expectativa de vida desses pacientes. O oxigênio domiciliar é usado há mais de 70 anos, e a ODP tem como base dois estudos da década de oitenta que demonstraram que o uso de oxigênio melhora a sobrevida de pacientes com DPOC. Existem evidências de que a ODP tem outros efeitos benéficos como melhora da função cognitiva e da capacidade de exercício e redução de hospitalizações. A ODP está indicada para outras doenças respiratórias que cursam com hipoxemia, segundo os mesmos critérios estabelecidos para a DPOC. Tem sido observado aumento no uso da ODP provavelmente pela maior expectativa de vida, maior prevalência de doenças respiratórias crônicas e maior disponibilidade de ODP no sistema de saúde. O primeiro consenso sobre ODP da Sociedade Brasileira de Pneumologia e Tisiologia foi publicado em 2000; após 22 anos, apresentamos esta versão atualizada. Este documento é uma revisão não sistemática da literatura, realizada por pneumologistas que avaliaram evidências científicas e diretrizes internacionais sobre ODP nas diversas doenças que cursam com hipoxemia e em situações específicas (exercício, sono e viagens aéreas). Estas recomendações, tendo em vista a prática clínica, oferecem diversos quadros com informações sobre indicações, fontes de oxigênio, acessórios e estratégias para melhor eficiência, efetividade e uso seguro da ODP, assim como um modelo para sua prescrição.

ABSTRACT

RESUMEN La producción científica sobre el término desarrollo se encuentra fragmentada a partir de intereses desarticuladores del capital. Este proceso ha desvirtuado las potencialidades de la sociedad para reencontrar lo comunitario como cualidad emancipadora del ser humano. La falta de unidad teórica y conceptual acerca del desarrollo ha sido tradicionalmente tratada por la sociología, la filosofía y la práctica política. Se plantea como objetivo identificar aspectos teóricos referidos a la cualidad comunitaria del desarrollo. El estudio tiene un enfoque marxista. Para la obtención de resultados, se emplean los métodos en el nivel teórico: analítico-sintético, sistémico-estructural, históricológico e inductivo-deductivo, y a nivel empírico, el análisis documental. Se enuncian consideraciones sobre el desarrollo desde una visión integradora que trasciende adjetivaciones y se fundamenta como un proceso real y concreto. Lo comunitario como cualidad transformadora de la actividad humana, concretado en los proyectos colectivos, constituye el principio teórico del desarrollo desalienador.


ABSTRACT The scientific production on the term development is found fragmented from disarticulating interests of capital. This process has distorted the potential of society to rediscover the community as an emancipating quality of the human being. The lack of theoretical and conceptual unity about development has traditionally been dealt with by sociology, philosophy and political practice. The objective is to identify theoretical aspects related to the community quality of development. The study has a Marxist approach. To obtain results, the methods are used at the theoretical level: analytic-synthetic, systemic-structural, historical-logical and inductive-deductive, and empirically, the documentary analysis. Considerations on development are enunciated from an integrating vision that transcends adjectives and is based on a real and concrete process. The community as a transforming quality of human activity, concretized in collective projects, constitutes the theoretical principle of disalienating development.

ABSTRACT

Resumen La aterosclerosis es una enfermedad que involucra múltiples mecanismos fisiopatológicos cuyo conocimiento no se ha dilucidado por completo. Con frecuencia, los avances científicos sobre la fisiopatología aterogénica generan que a diversas moléculas no consideradas previamente en el panorama de dicha enfermedad se les atribuyan acciones sobre el inicio o progresión de la misma. Un ejemplo representativo es el estudio de un nuevo mecanismo involucrado en el proceso aterogénico, consistente en la asociación entre el sistema de factores de crecimiento similares a la insulina (IGF) y la proteína plasmática A asociada al embarazo (PAPP-A). El sistema IGF es una familia de péptidos compuesto por 3 hormonas peptídicas, 4 receptores transmembranales y 6 proteínas transportadoras. El factor de crecimiento similar a la insulina tipo 1 (IGF-1) es el principal ligando del sistema IGF involucrado en la aterosclerosis coronaria y ejerce sus efectos mediante la activación del receptor IGF-1R en células de músculo liso vascular de las arterias coronarias o en macrófagos de placas ateroscleróticas. En células de músculo liso vascular promueve la migración y previene la apoptosis aumentando la estabilidad de la placa, y en macrófagos disminuye el transporte reverso de colesterol propiciando la formación de células espumosas. La regulación de la biodisponibilidad de IGF-1 en el endotelio se lleva a cabo por las proteasas de proteínas IGFBP, principalmente por la PAPP-A. En la presente revisión se abordan los mecanismos involucrados entre el sistema IGF y la PAPP-A en aterosclerosis coronaria con énfasis en los efectos moleculares producidos en células de músculo liso vascular y en macrófagos.


Abstract Atherosclerosis is a condition that involves multiple pathophysiological mechanisms and whose knowledge has not been fully elucidated. Often, scientific advances on the atherogenic pathophysiology generate that molecules not previously considered in the scene of this disease, were attributed actions on the onset or progression of it. A representative example is the study of a new mechanism involved in the atherogenic process, consisting of the association between the insulin-like growth factor (IGF) system and pregnancy-associated plasma protein-A (PAPP-A). Insulin-like growth factor system is a family of peptides that include 3 peptide hormones, 4 transmembrane receptors and 6 binding proteins. Insulin-like growth factor-1 (IGF-1) is the main ligand of the IGF system involved in coronary atherosclerosis. IGF-1 exerts its effects via activation of the IGF-1R receptor on vascular smooth muscle cells or macrophages. In vascular smooth muscle cells promotes migration and prevents apoptosis which increases plaque stability while in macrophages reduces reverse cholesterol transport leading to the formation of foam cells. Regulation of IGF-1 endothelial bioavailability is carried out by IGFBP proteases, mainly by PAPP-A. In this review, we address the mechanisms between IGF system and PAPP-A in atherosclerosis with emphasis on molecular effects on vascular smooth muscle cells and macrophages.

ABSTRACT

Se presenta el caso de una mujer de 44 años, blanca, ingresada en el Servicio de Medicina Interna del Hospital Clinicoquirúrgico Docente "Miguel Enríquez" por síndrome febril agudo y hematuria. En el examen físico realizado se notó la salida de lágrimas con sangre muy fluida, por el ángulo externo del ojo izquierdo. La inyección intradérmica en la cara dorsal del muslo derecho de 0,1 mL de sangre autóloga, indujo una reacción equimótica dolorosa en el sitio de la inyección. La inyección de 0,1 mL de solución salina al 0,9 % como control en el muslo contralateral, resultó negativa. Sobre la base del examen clínico y estas pruebas, se concluyó como un Síndrome de Gardner-Diamond. Esta entidad debe ser considerada en el diagnóstico diferencial de un síndrome purpúrico de etiología no bien precisada, fundamentalmente en pacientes con problemas psiquiátricos.


This is the case of a white woman aged 44, admitted in the Internal Medicine Service of "Miguel Enríquez" Clinical Surgical Hospital due to acute febrile syndrome and hematuria. At physical examination performed we noted a very high level of watering with presence of blood by left angle of left eye. The intradermal injection of 0,1 ml of autologous blood in dorsal part of right thigh, induced a painful ecchymotic reaction in injection site. The injection of 0.1 ml of 0,9% saline solution as control in contralateral thigh was negative. On the base of clinical examination and these tests, we conclude that it was a Gardner-Diamond syndrome. This entity must to be considered in differential diagnosis of a purpuric syndrome of a non-well established etiology, mainly in patients presenting with psychiatric disorders.

ABSTRACT

PURPOSE: To document etiology and predictive value of clinical diagnosis in laboratory confirmed viral diseases. METHODS: Reports of culture-positive cases of samples collected from patients presenting from January 1987 - December 2001 were evaluated. RESULTS: One thousand nine hundred and sixty-four (1964) cultures were submitted during 1987-2001. Twenty-six percent were positive (514). Human herpesvirus 1 was the most frequent agent isolated from all positive culture (56 percent). Adenovirus was the most common virus isolated from conjunctiva (66 percent), human herpesvirus 1 from lid and cornea (76 percent, 88 percent) and cytomegalovirus from vitreous (27 percent). Some unusual pathogens were recovered from conjunctiva as cytomegalovirus and from cornea as adenovirus, enterovirus and cytomegalovirus. Recognition of common viral syndromes was human herpesvirus 1 (88 percent), epidemic keratoconjunctivitis (88 percent), acute hemorrhagic conjunctivitis (70 percent) and varicella zoster virus (100 percent). However, some misdiagnosed cases were observed. Thirteen percent of conjunctivitis thought to be caused by herpes were due to adenovirus, 3.2 percent to Enterovirus, 3.2 percent to varicella zoster virus and 3.2 percent to human cytomegalovirus. Also, 5 percent of cases with a clinical diagnosis of herpes keratitis were caused by adenovirus and 2.7 percent by enterovirus. Finally, 4.8 percent of cases thought to be adenovirus conjunctivitis were herpes conjunctivitis. CONCLUSIONS: Human herpesvirus 1 remains the most frequently isolated virus from ocular sites in general (56 percent). Nonherpetic corneal isolates were in decreasing order: adenovirus, enterovirus and cytomegalovirus. Clinical and laboratory correlation was less than 90 percent. The most misdiagnosed cases were herpes conjunctivitis and keratitis, some cases of adenovirus conjunctivitis some cases of acute hemorrhagic conjunctivitis. It is essential that a rapid and...


OBJETIVOS: Documentar a etiologia e prever a importância do diagnóstico clínico em doenças virais oculares confirmadas em laboratório. MÉTODOS: Todos os relatórios de pacientes com cultura viral positiva durante o período de janeiro 1987 - dezembro 2001 foram analisados. RESULTADOS: Quinhentos e quatorze (514) casos foram encontrados. Em geral, herpesvírus 1 humano foi o agente mais freqüentemente isolado. Adenovírus foi o vírus mais comumente isolado da conjuntiva (66 por cento), herpesvírus 1 humano das pálpebras e córnea (76 por cento, 88 por cento respectivamente) e citomegalovírus do vítreo (27 por cento). Alguns agentes não usuais foram isolados da conjuntiva como citomegalovírus e da córnea como adenovírus, enterovírus e citomegalovírus. Reconhecimento das síndromes virais comuns foi: herpervírus 1 humano (88 por cento), ceratoconjuntivite epidêmica (88 por cento), conjuntivite aguda hemorrágica (70 por cento). Porém, alguns casos com diagnóstico incorreto foram observados. Treze por cento das conjuntivites com diagnóstico de herpes foram causadas por adenovírus, 3,2 por cento por enterovírus, 3,2 por cento por varicella zoster vírus e 3,2 por cento por citomegalovírus. Também, 5 por cento dos casos com diagnóstico clínico de ceratite herpética eram adenovírus e 2,7 por cento enterovírus. Além disso, 4,8 por cento dos casos em que se pensaram em conjuntivite por adenovírus, eram conjuntivite por herpes. Finalmente, 30 por cento dos casos em que se diagnosticaram conjuntive hemorrágica aguda, o agente etiológico era adenovírus. CONCLUSÃO: Em geral herpesvírus humano 1 continua a ser o vírus mais comum encontrado nas infecções oculares (56 por cento). Agentes não herpéticos isolados da córnea foram em ordem decrescente: adenovírus, enterovírus e citomegalovírus. A correlação entre o diagnóstico clínico e laboratorial foi menor do que 90 por cento. Um diagnóstico rápido e específico é essencial em casos de apresentações virais atípicas...

ABSTRACT

OBJETIVO: Verificar a distribuição dos genótipos da alfa-1-antitripsina e correlacionar com a gravidade da doença pulmonar em pacientes fibrocísticos. MÉTODO: Estudo clínico-laboratorial de corte transversal, com 70 pacientes fibrocísticos do Hospital Universitário da UNICAMP. Os fibrocísticos tiveram diagnóstico confirmado clínica e laboratorialmente. A gravidade da fibrose cística foi avaliada pelo escore de Shwachman. Todos os pacientes foram analisados para os alelos S e Z de alfa-1-antitripsina usando a reação em cadeia da polimerase. RESULTADOS: Nove pacientes (12,8 por cento) foram heterozigotos para os alelos S ou Z ou heterozigoto composto (SZ). Nenhuma diferença significativa foi encontrada na gravidade clínica da fibrose cística entre os genótipos da alfa-1-antitripsina. Nenhuma diferença com significância estatística foi encontrada quando os pacientes foram separados pela presença ou ausência da mutação deltaF508. CONCLUSÃO: Neste estudo, o primeiro realizado no Brasil sobre a associação entre deficiência de alfa-1-antitripsina e fibrose cística, não encontramos uma associação entre essa deficiência e a gravidade da fibrose cística.
