lung Q: restrictive

Restrictive lung disease:

Occupational/environmental disease in which an inhalant leads to interstitial fibrosis is called__________________

If a patient presented with an interstitial lung disease what would you expect to see on PFTs?

What causes the scarring seen in interstitial fibrosis?

Match AIP, UIP, NSIP, RBILD, DIP for each of the following

·      Patchy interstitial fibrosis

·      Best Rx is to quit smoking + steroids

·      AKA hamman-rich syndrome

·      Homogenous chronic interstitial PNA

·      Which has the best outcome

·      Diffuse interstitial infiltrates on xray leading to pulmonary fibrosis, cystic changes, diffuse scarring

·      Respiratory failure occurs over 2-5 years and ultimately progresses to honeycomb lung

·      Involvement of alveolar units with desquamted alveolar pneumocytes and macrophages

 All of the following are true concerning sarcoidosis except:

• a.     Non-caseating granulomas can be found in different organ systems including the heart, lung, brain, skin
• b.     Pulmonary involvement starts with the lung then progresses to mediastinal and hilar LAD
• c.      CD4 t cells activate macrophages to become epithelioid histioytes (T4 HST)
• d.     Increased CD4:CD8 ratio

match the following: silicosis, asbestosis, berylliosis

• ·      Birefringent
• ·      May present with pleural effusion/plaques
• ·      Interstitial granulomatous reaction
• ·      Interstitial fibrosis
• ·      Sclerotic nodule
• ·      Commonly seen in brake mechanics

 Farmers lung is an example of what type of  pneumonitis?
