Lung Fibrosis Flashcards
Lung fibrosis basal fibrosis Sx
clubbing
B/L fine crepts
Progressive SOB
dry cough
Granulomatous DPLD
Sarcoidosis
Hypersensitivity pneumonitis
Infections - TB
Vasculitis
Known causes/ associations of DPLD
Autoimmune- RA, scleroderma, SLE
Exposures- Asbestos, Silica radiation
Drugs- MTX, amiodarone, nitrofurantoin
Idiopathic interstitial pneumonias main three types
Chronic fibrosing
Acute/ Sub acute fibrosing
Smoking- related
Examples of chronic fibrosing idiopathic interstitial pneumonia
Indiopathic pulmonary fibrosis
Non- specific idiopathic interstitial pneumonia
Acute/ subacute fibrosing idiopathic interstitial pneumonia
cryptogenic organizing pneumonia
acute interstitial pnenumonia
smoking- related idiopathic interstitial pneumonia
Respiratory bronchiolitis interstitial lung disease
Desquamative interstitial pneumonia
Ix done on patients suspected with DPLD
CXR
HRCT
Lung function tests- DLCO
Bronchoalveolar lavage
Lung biopsy
Hemato tests
findings to be looked in CXR tests done for DPLD
reticular
reticulonodular
honycomb appearance
DLCO findings in DPLD patients
restrictive - reduced FEV1 and reduced FVC
but the ratio is normal or high
hemato tests are done in…. DPLD patients
DPLD associated with autoimmune diseases
physical examination findings of lung fibrosis
Inspection - apical flattening, reduced chest movements of the affected side
palpation- reduced movements, trachea deviated to the same side
percussion- dullness
auscultation- increased vocal resonance and fremitus, bronchial breathing
examples of upper lobe fibrosis
BREAST CLAP
berryliosis
radiation
extrinsic allergic alveolitis
allergic broncho- pulmonary aspergillosis
sarcoidosis
TB
Coal workers’ pneumoconiosis
Langerhan’s cell histiocytosis
Ankylosing spondylitis
Psoriasis
Examples of lower lobe fibrosis
RASCO
Rheumatoid arthritis
Asbestosis
Scleroderma
Cryptogenic fibrosing alveolitis
Other- NItroburantoin, MTX, amiodarone
