Restrictive Diseases Flashcards
restrictive diseases have reduced lung volumes because of –
an alteration in lung parenchyma
– and defects in chest wall or neuromuscular apparatus may also cause respiratory restrictions
pleural diseases
risk factors associated with poorer outcomes
older age, male, h/o cigarette smoking
collagen vascular diseases
scleroderma, systemic lupus erythematosus (SLE), ankylosing spondylitis
environmental exposures
medications, dust, ionizing radiation
Idiopathic fibrotic disorders –
idiopathic pulmonary fibrosis (IPF)
Infiltrative diseases -
sarcoidosis
etiology of scleroderma
unknown
scleroderma involves – sclerosis
progressive systemic
scleroderma is characterized by progressive interstitial fibrosis with atrophy and sclerosis of many organ systems such as
skin, internal organs, blood vessel walls
sclerodermic skin
leathery
pulmonary scleroderma: –, sclerosis and progressive volume loss
diffuse interstitial infiltrates
CXR of pulmonary scleroderma
fibrocystic spaces (honeycomb) mostly at lung base
systemic lupus erythematosus is a disorder of –
immune regulation
SLE: tissues are damaged by –
autoantibodies and immune complexes
SLE: antibodies are directed to –
blood, endothelial and neuronal cells
T/F: SLE is a significant cause of renal failure
true
cardiac manifestations of SLE
pericarditis and endocarditis
SLE may involve –, pneumonitis, interstitial lung diseases
pleural effusion
