Pulmo: Pneumonia Flashcards
Identify
Most common route of infection by microorganisms in pneumonia
Aspiration from the oropharynx
type of pneumonia
Grey hepatization
- Predominant cell: neutrophils
- Abundant: fibrin deposits
No new RBCs are extravasating, present RBCs have been lysed.
LOBAR pneumonia
identify what phase
Lung appears red and doughy due to proteinaceous exudates and bacteria in alveoli
Congestion and edema
1st 24hrs
identify what phase
RBC in the intracellular alveolar exudates, increased neutrophil influx
RED hepatization
2nd phase
type of pneumonia
- Poorly demarcated
- Neutrophilic infiltrates center in bronchi
- Most common etiologic organism: staphylococcal gram (+)
BRONCHOPNEUMONIA
type of pneumonia
- Inflammation in the:
- interstitial space
- alveolar wall
- connective tissue space
INTERSTITIAL PNEUMONIA
Usually caused by viral or atypical infection
type of pneumonia
Spread widely in both lung fields
Usually due to hematogenous spread
MILIARY PNEUMONIA
TB is the most common
what condition
Chest xray reveals meniscus sign
Homogenous density with a concave surface
PLEURAL EFFUSION
Identify
Most common cause of transudative effusion
HEART FAILURE
identify
Diagnostic laboratory marker for CHF
Pleuritic fluid
N-T pro-BNP
identify
2nd most common cause of exudative effusion
MALIGNANT EFFUSION
identify
Most common cause of exudative effusion
PARAPNEUMONIC EFFUSION
choose
Diagnostic TB markers from the following:
A. ADA >45 IU/L
B. Interferon gamma >140pg/ml
C. TNF-alpha
A, B
case
