Frequency of Radiologicaly Based Vertebral Column Deformities among Children with Cystic Fibrosis and Non Cystic Fibrosis Bronchiectasis

Abstract

Bronchiectasis is defined as an abnormal, permanent, and irreversible dilatation of the bronchi due to the destruction of the elastic and muscular components of their walls. That condition represents the final common pathway of several respiratory and systemic diseases. Its incidence exhibits wide variation among different populations, this wide variation might be accounted for by the use of different diagnostic methods and different criteria for patient selection. It has also been suggested, conversely, that thoracic kyphosis and scoliosis may contribute to poor lung function and impaired clearance of secretions through altered chest mechanics resulting from structural changes of the spine and rib cage. A vicious cycle may develop with deteriorating posture, lung function, and overall health and wellbeing. Adam’s test is the screening test which can detect the vertebral column deformities by inspection and palpation, Cobb’s angle for scoliosis and the standard (Cobb) measuring technique for kyphosis are the standard methods for quantitative assessment of the vertebral column curvature. This cross-sectional study was designed with the aim to evaluate frequency of scoliosis and kyphosis as types of vertebral column deformities that occur among children with cystic fibrosis and non cystic fibrosis bronchiectasis.It included 30 patients dignosed with bronchiectasis(13 patients as CF-bronchiectasis and17 patients as NCF-bronchiectasis) according to Pasteur et al 2010 and HRCT who were regularly following up at Pediatric Chest clinicat Children's hospital, Ain Shams University in the period from October 2014 till April 2015. Thirty- age and sex matched children - were also included as a control group, they were clinically free of chronic lung diseases for whom chest X-ray was routinely indicated. The mean age of patients included in the study is 8.450+4.30years, with mean agefor cystic fibrosis group was 6.576+4.577 years and for NCFB group was9.882+3.590years.
