heavy smokers, males > 40 years old

Question 20

what symptoms are seen in Buerger disease

smoking cessation

Question 23

what is the triad of Granulomatosis with polyangitis (aka Wegener’s)

Answer 23

1. focal necrotizing vasculitis
2. necrotizing vasculitis in the lung and upper airway
3. necrotizing glomerulonephritis
   => vessel death, lung death, kidney death

Question 24

what symptoms are commonly seen in patients with granulomatosis with polyangitis

Answer 24

upper respiratory tract Sx: nasal septum perforation, chronic sinusitis, otitis media, mastoiditis
lower respiratory tract Sx: hemoptysis, cough, dyspnea
renal Sx: hematuria, red cell casts

Question 25

what results will antibody testing reveal for granulomatosis with polyangitis

Answer 25

c-ANCA (aka PR3-ANCA) | note: PR3= anti-proteinase 3

Question 26

what will imaging reveal for granulomatosis with polyangitis

Answer 26

large nodular densities

Question 27

how are granulomatosis with polyangitis and microscopic polyangitis treated

Answer 27

corticosteroids and cyclophosphamide

Question 28

name a few ways that microscopic polyangitis is different from granulomatosis with polyangitis

Answer 28

unlike Wegener's, microscopic polyangitis does not involve the nasopharynx and does not cause granulomas also, microscopic polyangitis is p-ANCA (MPO-ANCA) positive rather than c-ANCA in Wegener's

Question 29

Answer 29

polyarteritis nodosa has lesions in various stages of development while all lesions in microscopic polyangitis are in the same stage
