A

necrotizing granuolmatous inflammation (kidney and lungs)
necrotizing vasculitis (sm/med vessels)
c-ANCA against neutrophil proteinase 3 (PR3)

A

exertional dyspnea

in women 20-40 y/o

A

recurrent pulmonary embolism

13
Q

Acute Respiratory Distress syndrome

A

hyaline membrane at capillary/alveolar interface,
neutrophil damage to type I and II pneumocytes,
inhibited recovery due to damage to type II pneumocytes

14
Q

Causes of pulmonary hypoplasia

A

oligohydramnios

decreased intrathoracic space

15
Q

Most common tracheoesophageal fistula type

A

blind esophagus with lower esophagus connected to trachea

16
Q

Extralobar sequestration

A

mostly on L side
polyhydramnios and edema can cause
external to lung w/ separate pleural lining

17
Q

Intralobar sequestration

A

assc with fibrosis/infections/bronchiectasis
usually lower lobe
aortic branch supplied
not in pleura

18
Q

Atelectasis

A

incomplete expansion of the lungs

collapse of previously inflated lung

19
Q

Resorption atelectasis

A
complete airway obstruction
mediastinal shift toward obstruction
excess secretions/asthma/foreign body
retraction of lung in airless state (cells filled with secretions)
most common type
20
Q

Compression atelectasis

A

mediastinal shift away from affected lung

pleural cavity filled (with fluid/air)

21
Q

Contraction atelectasis

A

fibrotic changes in lung/pleura
prevents full expansion
irreversible

22
Q

Pulmonary edema histology

A

engorged capillaries
hemosiderin laden macrophages
granular pink precipitate

23
Q

Acute respiratory distress syndrome (acute lung injury)

A

diffuse alveolar damage with hyaline deposition lining capillary/alveoli interface

24
