RESUMO

BACKGROUND: The interpretation of the chest radiograph may vary because it depends on the reader and due to the non-specificity of findings in tuberculosis (TB). We aim to assess the reproducibility of a standardized chest radiograph reading protocol in contacts of patients with pulmonary TB under the 5 years of age. METHODS: Descriptive, cross-sectional study with children under the age of five, household contacts of patients with confirmed pulmonary TB from Medellín, Bello and Itagüí (Colombia) between Jan-01-2015 and May-31-2016. Standardized reading protocol: two radiologists, blinded independent reading, use of template (Dr. Andronikou design) in case of disagreement a third reading was performed. Kappa coefficient for intra and inter observer agreement, and prevalence ratio were estimated of sociodemographic characteristics, TB exposure and interpretation of chest X-ray. RESULTS: From 278 children, standardized reading found 255 (91.7%) normal X-rays, 10 (3.6%) consistent with TB, and 13 (4.7%) other alterations. Global agreement was 91.3% (Kappa = 0.51). Inter-observer agreement between readers 1-2 was 90.0% (Kappa = 0.59) and 1-3 93.2% (Kappa = 0.59). Intra-observer agreement for reader 1 was 95.5% (Kappa = 0.86), 2 84.0% (Kappa = 0.51), and 3 94.7% (Kappa = 0.68). Greater inter-observer disagreement was between readers 1-2 for soft tissue density suggestive of adenopathy (4.6%), airspace opacification (1.17%) and pleural effusion (0.58%); between readers 1-3 for soft tissue density suggestive of adenopathy (4.2%), opacification of airspace (2.5%) and cavities (0.8%). CONCLUSIONS: Chest radiographs are an affordable tool that contributes to the diagnosis of TB, so having a standardized reading protocol showed good agreement and improves the reproducibility of radiograph interpretation.

RESUMO

Objetivo: establecer la frecuencia de empleo y explorar el papel que tiene la lactancia materna exclusiva hasta los 6 meses como factor protector para enfermedades prevalentes, en niños hasta de 5 años de edad en una determinada población colombiana. Materiales y métodos: se realizó un estudio de corte transversal en algunas instituciones educativas a nivel de jardín infantil de los municipios de Palestina, Ibagué y Pereira (Colombia). La escogencia de la población se efectuó mediante un muestreo por conveniencia. Se evaluaron las características basales, tipo de alimentación, tiempo de lactancia materna, tiempo de alimentación complementaria, enfermedades respiratorias, apendicitis, enfermedad diarreica aguda, diabetes mellitus, dermatitis, reflujo gastroesofágico, desnutrición, obesidad y afección cardiorrespiratoria. Resultados: participaron en el estudio 311 niños. Se encontró una frecuencia de lactancia materna del 92% (98,1% Ibagué, 90,5% Pereira, 87,9% Palestina) y una asociación significativa entre la lactancia materna y bronquiolitis, reflujo gastroesofágico, síndrome bronco obstructivo, desnutrición y afección cardiorrespiratoria. Conclusiones: se confirma la importancia de la lactancia materna como factor protector para enfermedades prevalentes en la infancia.

Objective: establishing the frequency of use and exploring the role of exclusive maternal breastfeeding for up to six months as a protection factor against prevalent diseases in children up to 5 years of age in a determined Colombian population. Materials and methods: a cross-sectional study was carried out in some kindergartens in the towns of Palestina, Ibagué and Pereira (Colombia). The study population was chosen by convenience sampling. Base characteristics such as type of feeding, maternal breastfeeding time, complementary feeding time, respiratory disease, appendicitis, acute diarrheic disease, diabetes mellitus, dermatitis, gastroesophageal reflux, malnutrition, obesity and cardiorespiratory affection were evaluated. Results: 311 children participated in the study. 92% maternal breastfeeding frequency was found (98.1% in Ibagué, 90.5% Pereira, 87.9% in Palestina) and a significant association was found between maternal breastfeeding and bronchiolitis, gastroesophageal reflux, broncho-obstructive syndrome, malnutrition and cardiorespiratory affection. Conclusions: the importance of maternal breastfeeding was confirmed as a protection factor for prevalent diseases during infancy.
