Flashcards in Restrictive Lung Diseases Deck (23):
1

FEV1/FVC ratio >/= 80%

Restrictive lung disease

2

hyaline memrane disease

neonatal respiratory distress syndrome

3

BL hilar lymphadenopathy, noncaseating granuloma; increase ACE and Calcium

Sarcoidosis

4

Drugs that cause pulmonary fibrosis

Bleomycin, busulfan, amiodarone, methotrexate

5

Type III/IV HS rxn to environmental allergen; usually seen in farmers and those exposed to birds

Hypersensitivity Pneumonitis

6

Rheumatoid arthritis and pneumoconioses with intrapulmonary nodules

Caplan Syndrome

7

"ivory white" calcified pleural plaques

Asbestosis

8

Ferruginous bodies

gold brown fusiform rods resembling dumbbells - asbestos

9

Part of lung asbestos affects

Lower Lobes

10

Part of lung silica and coal affect

Upper lobes

11

Black Lung Disease

Coal Workers' Pneumoconiosis

12

Asymptomatic condition found in urban dwellers exposed to sooty air

Anthracosis

13

Macrophages laden with carbon leading to inflammation and fibrosis

Coal Workers' pneumoconiosis

14

Foundries, Sandblasting, and mines

Silicosis

15

"eggshell" calcification of hilar LN

Silicosis

16

Silicosis increases the susceptibility to

TB & bronchogenic carcinoma

17

Risk factors of neonatal respiratory distress syndrome

prematurity, maternal diabetes (because insulin inhibits surfactant). C-section decreases release of fetal glucocorticoids

18

Tx of Neonatal respiratory distress syndrome

Maternal steroids before birth; artifical surfactant for infant

19

Surfactant deficiency

Neonatal respiratory distress syndrome

20

intra-alveolar hyaline membrane

Acute Respiratory Distress Syndrome

21

Cause of ARDS

trauma, sepsis, shock, gastric aspiration, uremia, acute pancreatitis, or amniotic fluid embolism

22

Tx of ARDS

tx underlying cause; ventilatoin with positive end-expiratory pressure (PEEP)

23

Near-complete opacification of the lungs with obscured cardiomediastinal silhouette

ARDS
