Lung 5 Flashcards
CAP causative agent
strep pneumonae
CAP atypical most common
mycoplasma pneumonia
CAP most severe atypical
legionella
CAP atypicals
myocpalsma pneumonia
legionella
chlamydia
CAP predisposing factors
age
chronic disease
immunodeficiency
defective spleen
lobar pneumonia
consolidation of a lobe or part of a lobe
bronchopneumonia
patchy consolidation of a lobe
main pneumonia diagnosis
CXR
elevated leukocyte count
bacterial CAP
stages of lobar pneumonia
congestion –> red hepatization –> gray hepatization –> resolution
identification of strep pneumo pneumonia
gram + lancet shaped diplococci
encapsulated
shaking rigors
lots of neutrophils
acute exacerbation of COPD
H influenzae
M catarrhalis
secondary to viral respiratory infections
Staph aureus
chronic alcoholic with gelatinous sputum
K pneumonia
pseudomonas
CF
burns
neutropenic
leginella
organ transplant patients
comes from water
pneumonia + ear/throat pain
mycoplasma
pneumonia + diarrhea
mycoplasma
legionella
pneumonia + abdominal pain
legionella
pneumonia + skin rash
mycoplasma
psittacosis
atypical pneumonia presentaion
patchy interstitial infiltrate (septae)
non productive cough
no WBC elevation
other weird signs
common cause nosocomial pneumonia
MRSA
pseudomonas
gram + cocci in nosicomial pneumonia
staph aureus
strep pneumoniae
gram - rods in nosicomial pneumoia
enterobacteriacease
pseudomonas
common cause VAP
gram - rods (pseudomonas)
risk factors for nosicominal pneumonia
hospitalization > 2 days nursing home recent IV therapy, chemo, wound care immunosuppression prolonged antibiotics ventilators
chronic pneumonia SE US
blastomyces
chronic pneumonia SW US with cocci on histo
coccidioides
common diffuse infiltrate in immunocompromised pneumonia
CMV
drug reaction
pneumocystis jroveci
common focal infiltrate in immunocompromised pneumonia
Gram neg bacterial S aureus aspergillus candida malignancy
uncommon diffuse infiltrate in imunocompromised pneumonia
bacterial pneumonia
aspergillus
cryptococcus
malignancy
uncommon focal infiltrate in immunocompromised pneumonia
cryptococcus
mucor
pneumocystis jroveci
legionella pneumophila
Ghon complex
calcified nodule in parenchyma and lymph nodes in latent TB
active TB presents as
acute bacterial pneumonia- consolidation, lymphadenopathy, pleural effusion
histology of TB
caseating necrosis granulomas
where does TB like to be
apices of upper lobes
cavitary lesion
erosion into airway
hemoptysis
erosion of vessels
miliary TB
lymph blood spread
TB diagnosis
CXR- consolidation/cavitation
AFB smear
culture
PCR
