“…The schoolchildren scored in the present study had normal lung function both at visits 1 and 2. In schoolchildren, bronchiectasis became an important morphological change and HRCT of the chest is considered the gold standard for diagnosing bronchiectasis [23]. This might, in part, explain why in the present study chest radiograph scores in schoolchildren showed less progression over the 3-yr period than the scores in preschool children.…”

The aim of the present study was to evaluate airway disease progression assessed by chest radiology, expiratory interrupter resistance (Rint,exp) and spirometry in young children with cystic fibrosis (CF) over a 3-yr period.Two chest radiographs combined with two Rint,exp measurements were performed with a 3-yr interval in 21 preschool children (age (mean¡SD) 3.2¡0.9 yrs) and 30 schoolchildren with CF (age 7.2¡1.9 yrs). Chest radiographs were scored using five different CF scoring systems and Rint,exp measurements were expressed as height-adjusted Z-scores. Spirometry was assessed in schoolchildren and the results were expressed as a percentage of predicted values.Chest radiograph scores worsened significantly over the 3-yr period and a tendency towards more pronounced changes was observed, especially for the Wisconsin score, in preschool children. Most preschool and schoolchildren had Rint,exp Z-scores within the normal range at start and follow-up, and the annual change in Rint,exp Z-score was not significant. In schoolchildren, only the forced expiratory volume in one second as a percentage of forced vital capacity declined significantly during the study period.In summary, in young children with cystic fibrosis, chest radiograph scores worsen significantly over time even while lung function remains stable.

“…The sensitivity rate in these studies has ranged from 60-100%, while specificity has been of the order of 90-100% [7][8][9][10][11][12][13]. However, there has not yet been a systematic study to evaluate CT of the thorax in comparison to bronchography for demonstration of CB in ABPA.…”

“…However, there has not yet been a systematic study to evaluate CT of the thorax in comparison to bronchography for demonstration of CB in ABPA. In studies of CT of thorax with the standard 10 mm sections at 10 mm intervals for demonstration of bronchiectasis, it was felt that the bronchi were not sharply visualized, due to partial volume averaging effect [7,8,11,13]. Furthermore, a gap of 10 mm between the sections may lead to small bronchiectatic lesions being missed [8,9,11], especially in bronchi that course horizontally as their axes lie parallel to the transverse plane.…”

Demonstration of central bronchiectasis (CB) with normal peripheral bronchi is an essential requirement for the diagnosis of allergic bronchopulmonary aspergillosis (ABPA). Although the results of bronchography remain the gold standard for demonstration of central bronchiectasis they are not always diagnostic. Moreover, it is an unpleasant invasive procedure which may be difficult to perform in a patient of allergic bronchopulmonary aspergillosis with acute severe asthma. In an attempt to find a safe and effective alternative to demonstrate central bronchiectasis computed tomography (CT) of the thorax was evaluated against bronchography. Twenty one patients with allergic bronchopulmonary aspergillosis underwent computed tomography of the thorax followed by bronchography. Of the 378 bronchopulmonary segments available for analysis, 42 had to be excluded because of consolidation or non-filling of the contrast dye, leaving 336 segments for evaluation. CB was identified on CT in all 21 patients. Detailed analysis of the visualized segments revealed that computed tomography (using 8 mm contiguous scans) identified 146 of the 212 segments showing central bronchiectasis on bronchography (sensitivity 70%) and 114 of the 124, read as normal on bronchography (specificity 92%). Supplemental 4 mm scans, used in 8 out of 21 patients improved the overall sensitivity of computed tomography to 83%, whilst the specificity remained unchanged at 92%. Thus, computed tomography of the thorax, being more acceptable to the patient, has the potential of being the investigation of choice for the demonstration of central bronchiectasis in patients with allergic bronchopulmonary aspergillosis.

“…3 There have been many computerized tomography (CT) scoring systems that evaluate the radiologic severity of bronchiectasis, although most of these were developed to evaluate the severity of cystic fibrosis (CF). 4 Many previous studies showed that the radiologic CT score was more sensitive in predicting disease progression than pulmonary function test (PFT) parameters in CF.…”

Background and objective: Non-cystic fibrosis (CF) bronchiectasis is a chronic airway inflammatory disease, exhibiting a diverse array of clinical courses. The purpose of this study was to determine the factors that predict radiologic progression of non-CF bronchiectasis during a long-term follow-up. Methods: We reviewed the electronic medical records that included pulmonary function test data from non-CF bronchiectasis patients, who were older than 18 years of age with a follow-up of computerized tomography for more than 5 years. The original Bhalla score was used to determine the radiologic severity of non-CF bronchiectasis. Results: A total of 155 patients (mean age, 59.6 years; male, 45.2%) were included for the final analysis. The mean follow up time was 7.11 ± 1.42 (5-10) years. The baseline Bhalla score was 9.52 ± 3.14 (4-19), and the change of Bhalla score was 0.55 ± 1.14 (À2 to 5). The Bhalla score was increased in 56 patients (36.1%) but not in 99 patients (63.9%). The Bhalla score change was significantly associated with the age at diagnosis (p = 0.037), body mass index (BMI, p = 0.012), chronic infection of Pseudomonas aeruginosa (p = 0.005) or isolation of nontuberculous mycobacterium (p = 0.042) in respiratory specimens. In a multivariate analysis, BMI and isolation of P. aeruginosa were significantly related with the Bhalla score change. Conclusion: The radiologic progression of non-CF bronchiectasis was associated with lower BMI and isolation of P. aeruginosa in respiratory specimens.
