Respiratory Flashcards
most common cause of inflammation of nasal mucosa
adenovirus
which pulmonary function test is decreased in obstruction
FEV1
which pulmonary function test is from full inspiration to full expiration
vital capacity
which pulmonary function test is from end of normal expiration + residual volume?
functional residual capacity
which part of respiratory tract has clara cells?
bronchioles
kid inhaled a peanut, what lung changes in lung?
resorption atelectasis
large tumor on chest wall compresses pleura, what changes you see in lung?
compression atelectasis
lung injury leads to scarring, what lung changes?
contraction atelectasis
complete whiteout, rapid onset and severe hypoxemia, septicemia, what histo changes after 2 weeks? obstructive or restrictive?
proliferation of type II cells, alveolar septal thickening
restrictive
complete whiteout, rapid onset and severe hypoxemia, septicemia, what histo changes after 2 days? obstructive or restrictive?
hyaline membranes
restrictive
TLC: increased
FVC: normal
FEV1: decreased lots
FEV1:FVC - reduced
COPD
only reversible COPD
asthma
permanent airspace enlargement distal to terminal bronchiole, no fibrosis, imbalance of antiproteases and antioxidants. disease? obstructive or restrictive?
emphysema, obstructive
chronic liver disease, polymorphism in TGFB increases severity, PiZZ. Disease? why liver disease?
alpha-1-antitrypsin -> emphysema
A1-AT made in liver, misfolded, accumulates -> disease
“moth eaten” upper lung, free floating alveolar septa. disease? subtype? what causes it?
emphysema, centrilobular (centriacinar), smoking
panlobular (panacinar) form of emphysema caused by what?
A1-AT deficiency
4 obstructive lung diseases
emphysema
chronic bronchitis
asthma
bronchiectasis
patient with dyspnea, sits down in a forward hunched position, skinny, hyperventilation. Disease? what would you see on xray (2 things)?
barrel chest
flat domes of diaphragm
patient presents complaining of persistent, productive cough for over 3 months over the past couple years, see no eosinophils. disease? 1 cause, 2 histo findings
chronic bronchitis
smoking/city dwelling
increased goblet cells
hypertrophy of seromucinous glands
hypersecretion of mucus
chronic bronchitis
increased Reid index
thickening of glandular layer in large airways (hypertrophy of seromucinous glands) - chronic bronchitis
hypoxia, hypercapnea, cyanosis, obese, cor pulmonale. disease?
chronic bronchitis “blue bloaters”
episodic cough, wheezing, (+) wheal and flare test. Disease? name the cytokines involved
asthma (obstructive)
IL-4: class switching to IGE
IL-5: eosinophils!!!!
IL-13: IgE production by B cells
wheezing post viral infection, serum IgE normal disease?
non-atopic asthma
runny nose, nasal polyp, bronchospasm, urticaria (hives), history of headache with aspirin treatment
drug induced asthma
curshmann spirals
asthma
