Diffuse infiltrative pneumopathies — definition?
Heterogeneous group with diffuse interstitial infiltration.
Pulmonary interstitium — function?
Supports airways, septa, and pleura tissues.
Interstitial infiltration pattern — types?
Cellular or fibrous, fibrosis is irreversible.
Diffuse interstitial opacities — radiologic feature?
Shared presentation across pneumopathies.
Pathogenesis — overshoot mechanism?
Persistent injury leads to fibrosis.
Acute PID — duration?
Less than 3 weeks.
Subacute/chronic PID — classification?
Known cause or unknown cause.
Major acute PID etiologies?
Infections, hemodynamic causes, ARDS, exacerbation.
Workup for PID — key step?
Multidisciplinary approach with imaging and tests.
HRCT — role?
Analyzes elementary imaging signs.
Major chronic PID causes — groups?
Connective tissue, granulomatous, exposure, drugs, others.
Treatment principle — cause?
Treat the identified cause.
Idiopathic pulmonary fibrosis — treatment?
Antifibrotic drugs; no steroids.
Sarcoidosis — management?
Surveillance or anti-inflammatory therapy.
Lofgren syndrome — treatment?
Anti-inflammatory approach.
IPF prognosis?
Median survival 2.5–3.5 years.
