31

yellow nodules in eyes

can be bx to make dx of sarcoidosis

32

calcium in sarcoidosis

disorder of vit D

nephrolithiasis, nephrocalcinosis, hypercalcuria

33

Dx of sarcoidosis

clinical, radiographic, histologic evidence of noncaseating granuloma in one or more organs

bronchoscopy with transbronchial lung bx

also elevated ACE - but this is nonspecific

34

pathognomonic for sarcoidosis

lofgrens syndrome

35

staging of sarcoidosis

CXR

0 normal
1 bilateral hilar adenoapthy
2 bilateral hilar adenopathy and parenchymal infiltrates
3 parenchymal infiltrates without lymphadenopathy
4 advanced parenchymal disease with fibrosis

36

PFT for sarcoidosis

restrictive ventilatory defect
-concurrent obstruction
-decrased DLCO

37

other testing for sarcoidosis

opthalmology exam
EKG
CVC
CMP
serum ACE level
Bx of involved organ

38

Tx of sarcoidosis

only for symptomatic patient**

prednisone - daily for 3 months
-monitor with FVC

taper off if improvement

39

sarcoidosis prognosis

spontaneous remission in 50% of patients at 3 years

lofgrens - best prognosis

2/3 remission after 10 years

1/3 with unrelenting disease

less than 5% die

40

silicosis

fibrotic lung disease cased by inhalation of crystalline silica in form of quartz

41

risk for silicosis

mining
tunneling
excavating
quarrying
stonework
foundries
sandblasting
ceramics

42

chronic silicosis

most common

20 or more years after exposure

silicotic nodule
-whorled hyalinized collagen fibers with peripheral zone of dust laden macrophages

asymptomatic - or complain of dyspnea and productive cough

43

accelerated silicosis

nodules after 3-10 years after exposure
-progressive clinical course

44

acute silicosis

6 months to 2 years after exposure

dyspnea, cough, weight loss, resp failure and death

alveolar filling process

45

progressive massive fibrosis

with silicosis

lesions are at least 1 cm in diameter and often larger

upper lobes

resp failure, cor pulmonale, weight loss, death

46

diseases associated with silicosis

TB
COPD
chronic bronchitis
collagen vascular disease
rheumatoid arthritis
scleroderma
lung cancer

47

CXR for silicosis

symmetric nodular pattern involving upper lobes

hilar lymphadenopathy with eggshell calcification is strongly suggestive

progressive massive fibrosis - coalescence of nodules with larger mass lesions

acute silicosis displays air space and interstitial pattern on x-ray

48

PFT for silicosis

normal early in chronic silicosis

later mixed pattern obstructive and restrictive

49

Dx of silicosis

x-ray changes and history of exposure

50

Tx of silicosis

irreversible
avoid further exposure
TB test
smoking cessation

consider lung transplant
