Summary
Computed tomography (CT) revealed significant airway abnormalities in relapsing polychondritis (RPC) patients. Findings included airway wall thickening, stenosis, malacia, calcification, and air trapping, impacting respiratory health.
Area of Science:
- Radiology
- Rheumatology
- Pulmonology
Background:
- Relapsing polychondritis (RPC) is a rare rheumatic disease.
- Characterized by recurrent inflammation of cartilaginous structures.
- Airway involvement is a significant cause of morbidity and mortality in RPC.
Purpose of the Study:
- To retrospectively evaluate airway and lung abnormalities in relapsing polychondritis (RPC).
- Utilized computed tomography (CT) for imaging assessment.
Main Methods:
- Retrospective analysis of chest CT examinations from 21 RPC patients (2004-2009).
- Two radiologists evaluated CT images for abnormalities.
- Noted findings included airway stenosis, malacia, air trapping, and wall thickening/calcification.
Main Results:
- 38.1% of patients showed major CT abnormalities.
- Common findings: airway wall thickening (7), stenosis (6), malacia (6), calcification (8), and air trapping (3).
- Additional findings included mediastinal lymph nodes (12), lung infection (4), and interstitial lung disease (6).
Conclusions:
- CT findings in RPC predominantly involve airway abnormalities.
- Key CT findings include airway wall thickening, stenosis, malacia, calcification, and air trapping.
- These findings are crucial for understanding and managing respiratory complications in RPC.

01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
01:19Chronic Obstructive Pulmonary Disease IV: Clinical Manifestations
Chronic Obstructive Pulmonary Disease, or COPD, is a long-term condition marked by persistent and only partially reversible airflow limitation. It involves two overlapping conditions—chronic bronchitis and emphysema—which often co-appear but differ in dominant symptoms and underlying mechanisms.Chronic Bronchitis FeaturesChronic bronchitis presents with a persistent productive cough and thick, sometimes purulent mucus due to airway inflammation, enlarged mucus glands, and goblet cell...
01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:19Pericarditis II: Clinical Features and Diagnostic Tests
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
01:23Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
01:25Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
