Tulane (HIGH YIELD) Flashcards
Appearance of bronchitis on CXR?
Normal (usually)
Haemophilus influenza specific culture
Require Hematin (X-factor) and NAD (V-factor) for chocolate agar
Virulence factor for invasive Haemophilus influenzae
PRP capsule
Can legionella be transmitted person-to-person?
No
Gram stain of chlamydial pneumonia
“Negative,” but gram stains poorly (cell wall lacks peptidoglycan)
What pneumonia pathogen’s replicative cycle has 2 forms: Elementary Body and Reticulate Body?
Chlamydial pneumonia
What is the “6 second test” for lung disease?
If forced exhale takes > 6 sec, you have obstructive lung disease
Effect of obstructive disease on FEV1/FVC ratio
Decr.
Effect of restrictive disease on FEV1/FVC ratio
Incr. or normal
A1AT deficiency genotypes
“Pi” = “Protease inhibitor”
PiMM: normal
PiMZ: heterozygotes, ~35% normal levels, protective
PiZZ: diseased
What chromosome is the gene for A1AT on?
14q
Clubbing with obstructive disease differential:
- Bronchiectasis
- Cystic Fibrosis
- Bronchiogenic carcinoma
Less important: - Intrapulmonary vascular malform
- Congenital heart disease (R to L shunt)
COPD pathogens (according to Tulane)
Haemophilus influenza, moraxella catarrhalis, strep pneumo
Th2 cytokine profile
IL-4, IL-5, IL-13 (Pathoma incl. IL-10)
Lung adenocarcinoma location
Peripheral
Important genes associated with lung adenocarcinoma
KRAS, EGFR
Carcinoid syndrome symptoms
Intermittent attacks of: Flushing, cyanosis (weakness?), diarrhea
Drugs that cause pulm fibrosis (according to Tulane)
Amiodarone, bleomycin, nitrofurantoin, azathioprine, gold
Low yield: methotrexate, busulfan and radiation
What specific lung pathology is “temporally homogenous”
DAD (ARDS, NRDS, AIP)
Interstitial (pulmonary) fibroblast foci are pathognomonic of what disease?
Idiopathic Pulmonary Fibrosis (UIP)
Sarcoidosis “pathognomonic” CXR finding
Hilar lymphadenopathy
Histopathologic inclusion(s) found in sarcoidosis
Asteroid bodies, Schaumann bodies
