ABSTRACT

En la actualidad existe un nuevo paradigma en el tratamiento de piezas dentales con grandes lesiones periapicales. Ello tiene como principal propósito la conservación de dichas piezas, la regeneración de su sistema de inserción y hueso alveolar. Todo esto es posible gracias a la innovación científico-tecnológica que plantea como alternativa, la utilización de una terapéutica dinámica, mínimamente invasiva intralesional, destinada a erradicar los microorganismos que conforman el biofilm periapical e inducir la capacidad autorreparativa del sistema inmune mediante el uso de un biomaterial de tercera generación (Licon-D) (AU)


Currently there is a new paradigm in the treatment of dental pieces with large periapical lesions. The main purpose is the conservation of these pieces, the regeneration of their insertion system and alveolar bone. All this is possible thanks to the scientific and technological innovation that poses as an alternative, the use of a dynamic, minimally invasive intralesional therapy, designed to eradicate the microorganisms that make up the periapical biofilm and induce the autoreparative capacity of the immune system through the use of a third generation biomaterial (Licon-D) (AU)

ABSTRACT

INTRODUÇÃO: A lesão apical ventricular é típica da cardiopatia chagásica e sua presença representa risco de fenômenos tromboembólicos. O objetivo deste trabalho é avaliar a frequência de LA à necropsia de portadores de cardiopatia chagásica crônica. MÉTODOS: Análise retrospectiva de necropsias de chagásicos maiores que 17 anos. Efetuada análise estatística comparativa das variáveis clínicas e dos achados necroscópicos entre o grupo A (com lesão apical) e o grupo B (ausência de lesão apical). RESULTADOS: Estudados 51 casos: 25 no grupo A (idade média de 53 anos, 64 por cento do sexo masculino)e 26 no B.. A LA localizava-se no ventrículo esquerdo em 80 por cento casos. No grupo B, a média de idade foi de 56 anos e 46,1 por cento eram do sexo masculino. A forma clínica prevalente nos dois grupos foi a miopática, mas arritmia cardíaca também esteve presente em ambos (57,9 por cento no grupo A e 32,1 por cento no B). Foi constatada a presença de trombos em 60 por cento dos casos do grupo A (53,3 por cento localizados na LA ) e 30,7 por cento no B; CONCLUSÕES: Houve predomínio da forma miopática nos casos com LA, com média de peso cardíaco maior em relação ao B. Em ambos os grupos observamos relação diretamente proporcional entre maior peso cardíaco e presença de tromboses. Houve predomínio do número de tromboses no grupo A, mais de 50 por cento eram localizadas na lesão, cujo diferencial clínico principal consistiu na presença maior de arritmias. A miopatia (com aumento de peso acima de 500g) foi primordial para aparecimento de tromboses.


INTRODUCTION: The presence of an apical ventricular lesion increases the risk of intracardiac thrombosis and thromboembolic phenomena. The study evaluated the incidence of apical lesions and intracardiac thrombosis in Chagas' heart disease patients at autopsy. METHODS: A retrospective review of autopsies of Chagas' heart disease patients was conducted. Statistical analysis included comparison of clinical variables and autopsy findings between two groups: group A (apical lesions) and group B (no apical lesions). RESULTS: A total of 51 cases of Chagas' disease patients were studied: 25 in group A (mean age 53 years-old; 64 percent male) and 26 in group B. Apical lesions were verified in the left ventricle in 80 percent of cases. The prevalent clinical subtype in both groups was myopathic, but significant cardiac arrhythmia was present in 57.9 percent of patients in group A, while 76.9 percent in group B did not present arrhythmias. Mean heart weight was 500.9g in group A and 408.4g in group B. The presence of thrombosis occurred in 60 percent of group A with 8 (53.3 percent) thrombi occurring in the apical lesion. CONCLUSIONS: The myopathic subtype was the most common clinical form in group A and the mean heart weight was statistically higher in this group. Clear prevalence of thrombosis was verified in group A, with 50 percent located in the apical lesion, whose main differential factor was a greater incidence of arrhythmias. Myopathy (heart weight above 500g) was primordial for the presence of thrombosis in both groups.

ABSTRACT

JUSTIFICATIVA E OBJETIVOS: A lesão apical (LA) é sede de tromboses e marcadora de mau prognóstico na doença de Chagas. O ecocardiograma bidimensional é um exame útil na avaliação de alterações morfofuncionais em cardiopatas chagásicos crônicos (CCC). O objetivo deste estudo foi avaliar a frequência da LA em CCC, diagnosticada por meio do ecocardiograma bidimensional com Doppler, e estudar clinicamente estes pacientes. MÉTODO: Realizou-se um estudo retrospectivo de prontuários de CCC submetidos ao ecocardiograma bidimensional com Doppler. Os pacientes foram divididos em dois grupos, na dependência da presença (Grupo A) ou ausência (Grupo B) da LA. Foram estudadas variáveis clínicas e ecocardiográficas, que foram submetidas à análise estatística.RESULTADOS: Foram incluídos 100 pacientes; 21 no grupo A [13-(61,9%) do sexo masculino; idade média de 61,10 anos] e 79 no B [46-(58,23 %) do sexo feminino; idade média de 57,01 anos]. Dos 50 pacientes miopatas, 70 batmopatas e 60 dromopatas observados, a LA esteve presente respectivamente em 17 (34,0%), 13 (18,6%) e 11 (18,3%). As três formas clínicas simultaneamente foram observadas em 26 pacientes, desses, sete (26,9%) apresentavam LA. A hipertensão arterial foi a comorbidade mais frequente, encontrada em 61 pacientes (61%), 11 (52,38%) eram do grupo A. No grupo B, 82,5% (52 pacientes) tinham fração de ejeção maior ou igual a 55, enquanto no grupo A, 26,3% (5 pacientes) a tinham abaixo de 55. Três casos de trombose foram diagnosticados ao Ecocardiograma; em dois o trombo se localizava na própria LA.(...)


BACKGROUND AND OBJECTIVES: The apical lesion (AL) is the seat of thrombosis and amarker of poor prognosis in Chagas disease. Bi-dimensional echocardiogram is a helpful tool in the evaluation of morphofunctional changes in chronic chagasic cardiopathy (CCC). The objective of this study was to evaluate the frequency of AL in CCC, diagnosed by bi-dimensional Doppler echocardiography and study these patients clinically. METHOD: A retrospective study of CCC medical records was conducted. The patients were submitted to a bi-dimensional Doppler echocardiogram and then divided into two groups, depending on the presence (Group A) or absence (Group B) of AL. We studied clinical and echocardiographic variables that were subjected to statistical analysis.RESULTS: 100 patients were included, 21 in group A [13 - (61.9%) males, average age 61.10 years old] and 79 in B [46 - (58.23%) females, average age 57.01 years old]. In this study we found 50 patients with myopathy, 70 with arrhythmias and 60 patients had intracardiac conduction disturbances. Among these patients, AL was present respectively in 17 (34.0%), 13 (18.6%) and 11 (18.3%). These three clinical forms were observed simultaneously in 26 patients and seven of them (26.9%) had AL. High blood pressure was the most common comorbidity which was found in 61 patients (61%); 11 (52.38%) of these patients had AL. In group B, 82.5% (52 patients) had an ejection fraction measured by echocardiography greater than or equal to 55; while in group A, 26.3% (5 patients) had an ejection fraction less than 55. Three cases of thrombosis were diagnosed by echocardiography; the thrombus was located in AL itself in two of these cases.(...)
