Pathology (not in Pathoma) Flashcards
(26 cards)
Febrile
leukocytosis
20% don’t have either of these
lower end of leukopenia in severe bacteremia
Failure to respond to normal empiric Abx therapy
think fungal pneumonia
Common influenza complication
S. aureus pneumonia
from influenza A/B complication
Empyema
puss-filled space
complication of pneumonia
may need to be drained
Urinary antigen testing
able to test for bacteria present in blood
“Patchy” pneumonia pattern
bronchial pneumonia
Infection distribution patterns in pneumonia
bronchial: pathy
lobar: consolidated more
Procalcitonin test
increased in bacterial infection but not viral disease
Common fungal pneumonia
blastomycoses
Bronchiectasis
permenant dilation of bronchioles
Cause of bronchiectasis
recurrent bronchial infection
Sx of bronchiectasis
cough
daily mucopurulent sputum
months/years
dyspnea/wheezing due to airway collapse
rhinitis and hemoptysis association
Strange extreme treatment for empysema
partial lung resection
gives rest of lung more space to expand
Status asthmaticus
what is it
sustained bronchoconstriction
needs urgent medical attention
Pneumococcus
S. pneumoniae
colonizes 20% of people
Definitive Dx of pneumococcus
grown in pleural fluid or blood
positive urine antigen
Splenectomy and pneumonia
vaccine against pneumococcus
encapsulated
CXR showing volume loss + pulmonary opacification
atelectasis
How to differentiate fungal nodule from lung cancer
central calcification
lung cancer typically too aggressive to calcify
Bird/bat droppings bugs
histoplasmosis
Pneumonia from bat droppings
histoplasmosis
Most common fungal infection around here
blastomycosis
How blastomycosis earns its name
very large yeast cells
Southwestern US fungi
coccidiomycosis
