I don't have access unfortunately. I appreciate the post though.
I'm just trying to gain an idea of what rheumatoid lung disease even is. I've read in some sources (which were vague, quite frankly) that it's a "collection" of lung disorders (whatever that means). UWorld, in contrast, mentioned it as pulmonary fibrosis; the attached article following the explanation led to just an abstract, and I couldn't get access to that article either.
