Flashcards in Pulm CC I - Truwit Deck (10):
1

What are the imaging findings seen in interstitial diseases?

What is the mnemonic used to recall these diseases (just the abbreviation, not each disease)?

"Scratchy" appearing infiltrates.

SHITFACED

2

Recall the interstitial infiltrates referred to in the mnemonic "SHITFACED".

S - Sarcoidosis

H - Hypersensitivity pneumonitis

I - Interstitial lung dz

T - Tumor or TB

F - Fungal

A - Asbestosis

C - Collagen vascular dz

E - Eosinophilic granuloma

D - Drugs

3

How does sarcoidosis appear on histology of lung biopsy?

Granulomas (epithelioid histiocytes, giant cells) in a "lymphatic" distribution. Relatively normal alveoli.

4

Recall the four stages of Sarcoidosis as determined by imaging findings.

Stage I - Hilar lymphadenopathy

Stage II - Hilar lymphadenopathy & Lung infiltrate

Stage III - Lung infiltrate

Stage IV - Fibrosis

5

What other organs are involved in sarcoidosis?

Eyes (Uveitis), skin (lupus pernio & erythema nodosum), CNS, heart, liver, joints, kidney...

6

How does ARDS appear on CXR?

Diffuse "white-out".

7

Recall the mnemonic used to recall alveolar infiltrates.

(and what it stands for)

PeCan PIE;

P - Pus

C - Cells (RBC, eosinophil, tumor)

P - Protein

I - Inflammatory elements

E - Edema

8

Recall the criteria needed for an ARDS diagnosis.

Acute onset (<7days), fluid overload, bilateral infiltrates.

9

With respect to assisted ventilation:

Is a higher or lower tidal volume better?

Is a higher or lower PEEP better?

Is liberal or conservative fluid resuscitation better?

For maximum survival and shortest time on the ventilator:

Low tidal volume

(PEEP not significant)

Conservative fluid resuscitation

10

What other techniques are helpful in managing ventilated ARDS patients?

What techniques do not make a difference?

Pronation, paralysis (maybe).

Short-term diet control and statins do not help. Beta-agonists (older) and surfactant (neonates) on a specific basis.
