lung-pulmonary infections Flashcards
what are the 3 patterns classically seen on xray in pneumonia patients?
lobal pneumonia
bronchopnemonia
interstitial pheumonia
what classification of pneumonia:
“consolidation of the entire lobe”
lobar pneumonia
what are the 2 most common bacterial causes of lobar pneumonia
strep pneumoniae and klebsiella pneumoniae
what are 4 things you see on gross exam of lobar pneumonia
- congestion
- red hepatization
- gray hepatization
- resolution
what classification of pneumonia:
“scattered patchy consolidation centered around bronchioles, often multifocal and bilateral”
bronchopneumonia
what classification of pneumonia:
“diffuse interstitial infiltrates”
interstitial (atypical) pneumonia
why is interstitial pneumonia considered atypical (symptoms)
presents with relatively mild upper resp symptoms (minimal sputum and low fever)
what bacteria usually cause aspiration pneumonia?
anaerobic bacteria of the oropharynx
what bacteria is the most common cause of secondary pneumonia after an infection with a virus
strep pneumoniae
how does one usually get klebsiella pneumoniae
enteric flora that is aspirated
what organism:
“thick mucoid capsule results in gelatinous sputum (current jelly)”
klebsiella pneumoniae
what pneumnonia is seen in cystic fibrosis patients? what type of pneumonia is that
pseudomonas aeruginosa (bronchopneumonia)
what 3 bronchopneumonias are seen superimposed onto COPD
haemophilus influenzae
morazella catarrhalis
legionella pneumophila
what organism:
“causes bronchopneumonia and best sen with silver stain”
legionella
what organism in this pneumonia:
“most common cause of atypical pneumonia, usually affects young adults”
myoplasma pneumoniae
