Round 1
True or false - DPLD (diffuse parenchymal lung disease) is a subset of ILD (interstitial lung disease)
What is false? Interstitium is a part of the parenchyma
Starting to smoke or increasing amount smoked can cause this.
What is acute eosinophilic pneumonia (AED)
True or False: 15 -40% of pts with radiation pneumonitis die from it.
False. Mortality in radiation pneumonitis is only 2%. 15 - 40% of pts getting radiation for chest tumors develop radiation pneumonitis.
These are 2 out of 4 classifications of DPLD based on eitiology (used mostly in pediatric DPLD classifications, but could be coming soon to adults)
What are lung-only (native parenchymal) disease, systemic disease, exposure-related disease, vascular disease
Pleural effusions from acute eosinophilic pneumonia (AED) have up to this percentage of eosinophils.
What is 50%?
These are 2 out of 5 abnormal breath sounds heard in radiation pneumonitis. Please also describe what the breath sounds are.
Pleural friction rub = crunching sound
Rales = irregular inspiratory crackles
Bronchial breath sounds = harsh, expiration is as long as inspiration
Fremitus = increased vibration over area of consolidation
Egophony = E sounds like A over area of consolidation
This is an example of a systemic disease causing DPLD (multiple possibilities)
What are RA, SLE, mixed connective tissue (MCT), Sjogren's, sarcoidosis
This is what happens to the extracellular matrix in pulmonary fibrosis
What is accumulation of the extracellular matrix?
These are signs of idiopathic pulmonary fibrosis on HRCT
What are bilateral reticulations and honey combing in periphery of lower longs?
Bilateral reticulations = irregular, short lines showing regions of fibrosis
Honeycomgin = thick walls fro fibrosis
These are symptoms which should lead you to consider DPLD
What are dyspnea, exercise intolerance and a non-productive cough?
Signs which should make you consider DPLD are lung crackles and finger clubbing (esp. in a young person)
True or false. The FEV1/FVC increases in pulmonary fibrosis and decreases in emphysema.
What is true? Obstruction causes decreased FEV1 in emphysema and restriction causes an increased FEV1 in pulmonary fibrosis (faster recoil of stiffer tissue).
THis is the expected life expectancy of a newly diagnosed pt with idiopathic pulmonary fibrosis
What is 5 years
