And Now, Your History…
 18 yo F with “Cough increased known *pulmonary
disease* patient”
 What primary chronic pulmonary diseases commonly
affect the pediatric population?
 What chronic pulmonary diseases with clinically
significant extra-pulmonary manifestations
commonly affect the pediatric population?

And The Diagnosis…
 Cystic Fibrosis
 Mutation to CFTR on chromosome 17 that results in
malfunction to varying degrees
 Results in thick mucus secretions that tend to obstruct
hollow secretory structures (bile and pancreatic ducts,
airways, bowel, sinuses, vas deferens/fallopian tubes, etc.)
 Can lead to chronic bronchitis-type pulmonary disease,
chronic rhinosinusitis, chronic pancreatitis/pancreatic
failure, meconium ileus/SBO, biliary
cirrhosis/cholelithiasis, infertility, poor bone
mineralization, HPOA
 Airways become colonized by bacteria, most commonly
Staph aureus, H. influenzae, and P. aeruginosa—chronic
lung infections that are frequently resistant to treatment
 Due to both genetic resistance and difficulty of delivering
sufficient concentrations of antibiotics through thick mucus

Role of radiography
 Lung disease is the most common cause of CF-related
morbidity and mortality—diagnosis, recognition, and
follow-up for progression are paramount!
 Findings on CXR include hyperinflation (earliest sign),
prominent bronchovascular markings (upper lobes
first), peribronchial cuffing (bronchiectasis), cyst
formation (late), kyphosis (late), flattened diaphragm
(late), PTX (late)
 In advanced stages, CXR may not correlate with clinical
changes
 CT—can define extent of bronchiectasis (if focal, may
be resectable)
