Correlation between Bhalla score and spirometry in children and adolescents with Cystic Fibrosis / Correlação entre escore de Bhalla e espirometria em crianças e adolescentes com fibrose cística

Objective: to correlate the findings of high resolution computed tomography of the chest based on the Bhalla score with the clinical data and spirometry in children and adolescents with cystic fibrosis, and to study the concordance between two radiologists for the Bhalla score and its categories. Methods: we evaluated the medical records of 23 patients from the outpatient clinic. The items evaluated included age, weight, height, height/age Z-score, weight/age Z-score, body mass index (BMI), O2 saturation, spirometry and Bhalla score. Results: the patients had a mean age of 17.4 years ± 5.7 years, with fifteen females and eight males. There was good correlation between Bhalla score and spirometry (FVC-r =0.718, p<0.001; FEV1-r=0.830, p<0.001; FEF25-75%-r =0.786, p<0.001; FEV1/FVC-r=0.714, p<0.001). It was also noted that some patients with FEF25-75%> 70% already had changes in their final Bhalla score. In the analysis of the concordance between the examiners a Kappa coefficient of 0.81 (p <0.001) was found, and an intraclass correlation coefficient of 0.98. Conclusion: a good correlation between Bhalla scores with spirometry confirmed its usefulness in evaluating and monitoring patients with cystic fibrosis, given it can be used both in patients who are unable to perform spirometry as well as for a pooled analysis of the two examinations since the HRCT scans show early changes in patients with normal function tests. .

Objetivo: correlacionar os achados da tomografia computadorizada de alta resolução (TCAR) do tórax, com base no escore de Bhalla, com os dados clínicos e a espirometria em crianças e adolescentes com fibrose cística (FC), além de estudar a concordância entre dois médicos radiologistas para o escore de Bhalla e suas categorias. Métodos: foram avaliados os prontuários e os exames de 23 pacientes do ambulatório. Os itens avaliados foram idade, peso, altura, escore Z altura/idade, escore Z peso/ idade, índice de massa corpórea (IMC), saturação de O2, espirometria e escore de Bhalla. Resultados: os pacientes avaliados tinham média de idade de 17,4±5,7 anos, sendo 15 do sexo feminino e 8 do sexo masculino. Houve boa correlação entre o escore de Bhalla e a espirometria (CVF-r = 0,718, p < 0,001; VEF1-r = 0,830, p < 0,001; FEF 25-75%-r = 0,786, p < 0,001; VEF1/ CVF-r = 0,714, p < 0,001). Nota-se, ainda, que alguns pacientes com FEF 25-75% > 70% já apresentavam alterações na nota final do escore de Bhalla. Na análise da concordância entre os examinadores, foi encontrado coeficiente kappa de 0,81 (p < 0,001) e coeficiente de correlação intraclasse de 0,98. Conclusão: a boa correlação do escore de Bhalla com as provas de função pulmonar confirma a sua utilidade na avaliação e no acompanhamento dos pacientes com FC, podendo ser utilizado tanto para pacientes que são incapazes de realizar a espirometria quanto para uma análise em conjunto dos dois exames, uma vez que a TCAR mostra alterações precoces em pacientes com espirometrias normais. .

Bronquiectasias / Bronchiectasis

Säo revisados de modo sumário dados históricos, epidemiológicos, patogenia e achados anatomopatológicos das bronquiectasias. Discutem-se os métodos diagnósticos e, com mais detalhe, o tratamento, destacando-se o papel atual da cirurgia no manejo dessa afecçäo

[ value of computed tomography in the diagnosis and staging of bronchiectasis]

Basing themselves on literature data, the authors specify the tomodensitometric semiology of bronchiectasis and locate the place of the computed tomography [C.T] in the diagnosis and staging of bronchiectasis in comparison with standard chest radiograph and bronchography They notice the advantages and limits of each method of examination The C.T, as non invasive examination which revolutionized the medical imaging in the last years, intervenes at all the stages of diagnosis of bronchiectasis. Recognition morphologic type, extension and associated damages. But technical Conditions are indispensable, as achievement of thin-section C.T, Judicious choice of windows with use of wide "bronchic" Window and apparatus with high Space resolution. At present, the choice between C.T and bronchograpy in the diagnosis of bronchiectasis seems to depend on quality of tomodensitometric images, localized or diffuse bronchiectasis and degree of Clinical suspicion The C.T of thorax must be done at any suspicion of bronchiectasis and only after the study of its results will be established the management. It seems that bronchography has no more to be indicated at first intention, but it restes indicated in case of discordance between a very suggestive symptomatology and a doubtful C.T. and in case of limited but complicated bronchiectasis which can undergo surgical operation
