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, meconiumileus/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 Katkin, Julie P. “Clinical manifestations and diagnosis of cystic fibrosis.” Uptodate.com.

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) Katkin, Julie P. “Clinical manifestations of pulmonary disease in cystic fibrosis.” Uptodate.com.
