Resumo Fundamento: A dilatação das artérias coronárias é a principal complicação da Doença de Kawasaki (DK) e, além de algumas características clínicas, é comum à DK e a doenças exantemáticas febris (DEFs). Objetivo: Avaliar se crianças com DEF e que não têm critério para DK apresentam alterações nas dimensões das artérias coronárias. Métodos: Foi realizada ecocardiografia nas primeiras duas semanas da doença em crianças com idade inferior a 10 anos, que apresentaram febre e exantema e nenhum outro critério de DK. Para comparar com pacientes com DK, fizemos a revisão de ecocardiogramas e prontuários médicos de pacientes com diagnóstico de DK dos últimos cinco anos. Ectasia coronária foi avaliada usando escore Z das artérias coronárias. As médias das dimensões das artérias coronárias foram comparadas pelo teste z, e um nível de significância de 0,05 foi adotado. Resultados: Foram incluídos no estudo 34 pacientes, 22 (64,7%) com diagnóstico de DEF e 12 (35,2%) com diagnóstico de DK. Usando o escore Z das artérias coronárias, observou-se dilatação em algum dos ramos da artéria coronária em seis (27,2%) pacientes com DEF. Conclusão: Uma porcentagem importante dos pacientes com DEFs apresenta dilatação das artérias coronárias.

Abstract Background: Coronary dilatation is the most important complication of Kawasaki disease (KD) and, in addition to some clinical characteristics, is common to KD and febrile exanthematous illnesses (FEIs). Objective: To assess whether children with FEI, who do not meet the criteria for KD, have changes in coronary arteries dimensions. Methods: Echocardiography was performed within the first two weeks of the disease in patients < 10 years with fever and exanthema without other KD criteria. To make a comparison with KD patients, we reviewed the echocardiograms and medical records of patients with a diagnosis of KD of the last five years. Coronary ectasia was assessed using Z scores of coronary arteries. The means of the dimensions of the coronary arteries were compared with a z test and a level of significance of 0.05 was adopted. Results: A total of 34 patients were included, 22 (64.7%) with FEI, and 12(35.2%) with a diagnosis of KD. Using the Z scores of coronary artery, a dilation of any of the coronary artery branches was observed in six (27.2%) patients with FEI. Conclusions: An important percentage of patients with FEI has coronary artery dilation.

If the development of the concept of "self" as a unit distinct from the environment ontogenetically follows the development of the concept of "us", then psychosocial constructs would play a very important role in explaining psychological constructs. The current study explores to what extent the psychosocial construct "family strength" can be used to predict the psychological constructs "psychological well-being" and "internal locus of control". Three different scales were administered to a non-probability sample of 400 subjects (153 males and 247 females) to measure family strength, psychological well-being and internal locus of control. Structural Equation Models found that 67% of the variance in psychological well-being and 59% of the variance in internal locus of control were predicted by "family commitment-trust" with good data adjustment (χ2/df = 1.78, GFI = .95, AGFI = .94, and NFI = .92). These findings show the primacy of the psychosocial dimension over the psychological dimension. The article discusses the implications of these findings for professional healthcare practice.

Si la adquisición del concepto de sí mismo como unicidad diferenciada del mundo es ontogenéticamente posterior a la adquisición del concepto de "nosotros", los constructos psicosociales tendrían un importante peso explicativo sobre los constructos psicológicos. La presente investigación tiene como objetivo estudiar el peso explicativo del constructo psicosocial fortaleza familiar sobre los constructos psicológicos bienestar psicológico y locus de control interno. Tres escalas de fortaleza familiar, bienestar psicológico y locus de control y un cuestionario socio-demográfico fueron aplicados a una muestra no probabilística de 400 participantes de población general (153 hombres y 247 mujeres). Se halló mediante modelamiento de ecuaciones estructurales que 67% de la varianza del bienestar psicológico y 59% de la varianza de locus de control interno eran predichas por compromiso-confianza familiar con buen ajuste a los datos (χ2/gl = 1.78, GFI = .95, AGFI = .94 y NFI = .92). Así lo psicosocial mostró un peso significativo sobre lo psicológico. Se discuten las implicaciones de los hallazgos para la práctica de los profesionales de la salud.
