Q

What are the FEV1/FVC ratios for restrictive lung diseases?

A

slightly >/= 0.8
In restrictive lung disease, the FEV1 and FVC are equally reduced, thus, the FEV1/FVC ratio should be approximately normal, or slightly increased

Q

Organizing pneumonia

  • Is it infectious?
  • histo pattern?
  • how do you treat it?
A

BOOP!
Non infectious: usually idiopathic secondary to CVD, drugs, HP, aspiration

  • Bilateral peripheral alveolar opacities “fuzzy nodules”
  • Intraluminal plugs of granulation tissue

Very steroid responsive

Q

Eosinophilic pneumonia:

  • presentation
  • treatment?
A
  1. Acute eosinophilic pneumonia
    - mimics ARDS (sim. to acute interstitial pneumonia)
  2. Chronic eosinophilic pneumonia
    - more in nonsmokers and women

lots of eosinophilic infiltrates (chronic has fibrosis and macrophages)

steroid responsive

Q

smoking related interstitial lung diseases (ILD):

A
  1. respiratory bronchiolitis (RB-ILD)
  2. Desquamative interstitial pneumonia (DIP)
  3. Langerhans cell histocytosis (LCH)
17
Q

What lung disease presents with accumulation of “dusty brown” macrophages?

A

the smoking related ILDs:

  1. respiratory bronchiolitis (RB-ILD)
    - bronchiocentric macrophages
  2. Desquamative interstitial pneumonia (DIP)
    - macrophages filling distal airspaces
18
Q

What pathogen is most common in:
community acquired pneumonia, -give typical vs atypical ones.

hospital acquired pneumonia?

A

community acquired pneumonia?

  • Strep pneumoniae (typical)
  • Mycoplasma pneumoniae (walking - atypical), virus (atypical)

hospital acquired pneumonia?

  • Staph (bc they get it from the staff!) MRSA
  • SPACE
19
Q

Lymphoid interstitial pneumonia:

  • usually associated with?
  • radiology?
  • Histo?
  • treat?
A

usually associated with autoimmune diseases or immunodeficiency. Can transform to pneumonia.

  • centrilobular nodules
  • germinal centers
  • immunosuppression
20
Q

Eosinophilic pneumonia:

  • presentation
  • treatment?
A
  1. Acute eosinophilic pneumonia
    - mimics ARDS (sim. to acute interstitial pneumonia)
  2. Chronic eosinophilic pneumonia
    - more in nonsmokers and women

lots of eosinophilic infiltrates
steroid responsive

21
Q

Lymphangioleiomyomatosis

  • what is it?
  • what complications are common?
  • treatment?
A

cystic lung disease only in young women

pleural effusions, spontaneous pneumothorax

anti-estrogen therapy

22
Q

Hypersensitivity pneumonitis

  • what is it?
  • symptoms
  • radiology?
  • Histo?
A

immunologic response to inhaled antigen
(Acute and Chronic - just like eosinophilic P)

cough. DOE

upper lobe predominant

inflammation with poorly formed granulomas

23
Q

Sarcoidosis:

  • which organs most affected?
  • presentation?
  • do they have restrictive or obstructive pattern?
  • histo?
  • treatment?
A
  • Lungs, eyes, Skin
  • Lymphadenopathy, chest pain, cough, wheezing,
  • may be mixed pattern
  • non-caseating granuloma
  • treatment often not necessary
24
Q

What bacteria is most common in:
community acquired pneumonia?
hospital acquired pneumonia?

A

community acquired pneumonia?
- Strep pneumoniae

hospital acquired pneumonia?

  • Staph (bc they get it from the staff!) MRSA
  • SPACE
25
Q

If pt has sepsis, what should you be suspicious of? Describe its treatment.

A

> 50% of causes of ARDS result from sepsis

If ventilating the patient, make sure TIDAL VOL IS LOW - lungs are healing bro,
