Reproducibility of a protocol for standardized reading of chest X-rays of children household contact of patients with tuberculosis / Lina Marcela Cadavid Álvarez ; Lucila Beatriz Molinares Arevalo    

Público ISBD Título : Reproducibility of a protocol for standardized reading of chest X-rays of children household contact of patients with tuberculosis Tipo de documento : documento electrónico Autores : Lina Marcela Cadavid Álvarez, ; Lucila Beatriz Molinares Arevalo, Fecha de publicación : 2022 Títulos uniformes : BMC Pediatrics Idioma : Inglés (eng) Palabras clave : Tuberculosis  Pulmonary  Latent Tuberculosis  Clinical Protocols  Radiography  Thoracic  Observer Variation  Reproducibility of Results Resumen : 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.

Pulmonary imaging in coronavirus disease 2019 (COVID-19): a series of 140 Latin American children / Lina Marcela Cadavid Álvarez

Objective: The purpose of the study was to analyze the imaging findings of pulmonary COVID-19 in a large pediatric series. Materials and methods: Children with SARS-CoV-2 infection confirmed by either quantitative reverse transcription-polymerase chain reaction from nasopharyngeal swabs or presence of circulating immunoglobulin M (IgM) antibodies and who underwent chest radiograph or CT or both were included in this retrospective multicenter study. Three pediatric radiologists independently reviewed radiographs and CTs to identify the presence, localization, distribution and extension of pulmonary lesions. Results: We included 140 children (71 female; median age 6.3 years, interquartile range 1.6–12.1 years) in the study. Peribronchial thickening (93%), ground-glass opacities (79%) and vascular engorgement (63%) were the most frequent findings on 131 radiographs. Ground-glass opacities (91%), vascular engorgement (84%) and peribronchial thickening (72%) were the most frequent findings on 32 CTs. Peribronchial thickening (100%), ground-glass opacities (83%) and pulmonary vascular engorgement (79%) were common radiograph findings in asymptomatic children (n=25). Ground-glass opacity and consolidation were significantly higher in children who needed intensive care admission or died (92% and 48%), in contrast with children with a favorable outcome (71% and 24%, respectively; P Mención de responsabilidad : Carlos F.
