Sketchy: Pneumocystis Flashcards
1
Q
How is PCP different from bacterial PNA?
A
- non-productive cough
- no consolidations on CXR
- ground-glass appearance on CXR
2
Q
Cue:
- ping pong table is made of glass but is cracked and being held up by silver discs
A
- PCP = ground glass appearance on CXR
- silver = methamine silver stain
- disc = disc-shaped yeast
3
Q
What is the tx for PCP?
A
- Bactrim (Trimethoprim-Sulfamethoxazole)
- Pentamadine (if sulfa allergy)
4
Q
Cue:
- player squirting water into his mouth with a water bottle labeled “BAL”
A
bronchoalveolar lavage (BAL) to diagnose PCP
5
Q
Cue:
- ping pong player with a cane
A
- ping pong (PP) = Pneumocystic pneumonia (PCP)
- cane = immunocompromised
6
Q
Cue:
- backhand in front of a jar of ping-pong balls shaped like eggs and pentagon-shaped paddles
A
- tx for PCP:
- backhand = Bactrim
- eggs = sulfur = sulfa drugs (TMP-SMX)
- pentagon = Pentamidine
7
Q
PCP is associated with a CD4+ count of _____.
A
less than 200
8
Q
How is Pneumocystis jiroveci transmitted?
A
respiratory
9
Q
How is the PCP diagnosis confirmed?
A
bronchoalveolar lavage (BAL) –> methamine silver stain of sample –> disk-shaped yeasts
10
Q
Cue:
- “Aid for AIDS” sign
A
Pneumocystis jiroveci = associated with AIDS
11
Q
Cue:
- scoreboard shows 20-0
A
20-0 = 200 = CD4+ less than 200 for PCP
12
Q
What causes pneumocystic pneumonia (PCP)?
A
Pneumocystis jiroveci
13
Q
What kind of pneumonia is PCP?
A
diffuse, interstitial
14
Q
What is the prophylaxis for PCP?
A
Bactrim (Trimethoprim-Sulfamethoxazole)
15
Q
How does Pneumocystis jiroveci present in non-immunocompromised pts?
A
it’s asymptomatic
