title: A neglected problem of developing countries: Noncystic fibrosis bronchiectasis.
abstract: BACKGROUND
  Bronchiectasis has been defined as the abnormal and permanent dilation of the bronchi. It is still an important problem in many developing countries.
  
  
  OBJECTIVE
  The aim of this study was to identify the chacteristics and underlying etiology of children followed with the diagnosis of noncystic fibrosis bronchiectasis.
  
  
  METHODS
  Children with bronchiectasis confirmed with high-resolution computed tomography were enrolled into the study. The data of the patients, including symptoms of the disease, age at the onset of symptoms, findings of physical examination, labrotory investigations performed in order to identify the etiology of bronchiectasis, etiology of bronchiectasis if found, radiologic findings and treatment modalities were noted.
  
  
  RESULTS
  Sixty-six children between 1 and 17 years were included in the study retrospectively. Forty-four of them were males (66.7%) and 22 (33.3%) were females. The most common presenting symptoms were cough (100%) and sputum expectoration (50%). An underlying etiology was identified in 44 (66.7%) of the study subjects. The four most common underlying causes were found as infections (21.2%), asthma (16.7%), aspiration syndromes and/or gastroesophageal reflux disease (9.1%) and immunodeficiency syndromes (7.6%), respectively.
  
  
  CONCLUSIONS
  Identifying an underlying etiology will have a significant effect on the management of noncystic fibrosis bronchiectasis. Defining the cause of bronchiectasis may also decrease its incidence, progression and complications.
