Study Notes
Chronic Obstructive Pulmonary Disease (COPD)
- COPD is a chronic, progressive lung disease characterized by airflow limitation and abnormalities in the airways and alveoli.
- Chronic bronchitis is defined by a cough with sputum production for at least 3 months per year for 2 consecutive years.
- Emphysema is characterized by the abnormal dilatation of airspaces distal to the terminal bronchiole, leading to destruction of the alveolar walls.
- Emphysema affects the small airways, while chronic bronchitis affects the large airways.
- Centriacinar emphysema is the most common type of emphysema and is often seen in smokers.
Obstructive Sleep Apnea Syndrome (OSAS)
- OSAS is a sleep disorder characterized by repeated episodes of upper airway obstruction during sleep, leading to snoring, pauses in breathing (apnea), and reduced breathing (hypopnea).
- The severity of OSAS is measured by the Apnea Hypopnea Index (AHI), which is the number of apneas and hypopneas per hour of sleep.
- An AHI of 30 or more is considered severe OSAS and typically necessitates treatment with Continuous Positive Airway Pressure (CPAP).
- Risk factors for OSAS include: obesity, central fat distribution, male sex, age 50-60 years, postmenopausal state, alcohol use, sedative use, and smoking.
- Complications of OSAS include: sudden cardiac death, stroke, congestive heart failure, and metabolic syndrome.
- Management of OSAS includes polysomnography (sleep study) and CPAP.
Pleural Effusion
- A pleural effusion is an abnormal accumulation of fluid in the pleural space, the space between the lungs and the chest wall.
- Pleural effusions can be transudative or exudative.
Transudative Pleural Effusion
- Transudative pleural effusions are caused by increased hydrostatic pressure or decreased oncotic pressure in the capillaries.
- Causes of transudative pleural effusions include: congestive heart failure, cirrhosis, nephrotic syndrome, hypoalbuminemia, and hypothyroidism.
Exudative Pleural Effusion
- Exudative pleural effusions are caused by inflammation or infection.
- Causes of exudative pleural effusions include: pneumonia, tuberculosis, malignancy, and connective tissue disorders.
Pleural Effusion with Tuberculosis
- Pleural effusion due to tuberculosis typically occurs in individuals aged 20-30 years, with a female predominance.
- It is often associated with recent exposure to tuberculosis.
- Patients with pleural effusion due to primary tuberculosis may develop pulmonary tuberculosis in 25-30% of cases within 5-10 years.
Empyema
- Empyema is a complicated parapneumonic effusion characterized by the presence of macroscopic pus in the pleural space.
- Empyema is a common complication of parapneumonic effusions.
- Low pleural fluid pH can indicate complicated parapneumonic effusion, rheumatoid arthritis, or malignancy.
Chylothorax
- Chylothorax is a milky white pleural effusion caused by lymphatic rupture, most commonly triggered by trauma, tuberculosis, or lymphoma.
Pseudochylothorax
- Pseudochylothorax is a milky white pleural effusion that mimics chylothorax but is not actually due to lymphatic leakage.
- The milky color is due to high levels of cholesterol crystals in the pleural fluid caused by inflammation.
- Often associated with tuberculosis or rheumatoid arthritis.
Chronic Bronchitis (Large Airways)
- Bronchospasm is increased in chronic bronchitis, but less so than in asthma.
- Mucus secretion is also increased in chronic bronchitis.
- Epithelial necrosis is absent in mild chronic bronchitis, but squamos metaplasia is present.
Emphysema (Small Airways)
- Inflammation is evident in the small airways, with inflammatory exudate in the lumen.
- Alveolar attachments are disrupted.
- The alveoli are easily inflatable due to decreased elastic recoil pressure (ERP).
- The airway wall thickens with inflammatory cells, including macrophages, CD8+ cells, and fibroblasts.
- Emphysema is characterized by peribronchial fibrosis and lymphoid follicle formation.
- Emphysema causes hyperinflation of the lungs (increased total lung capacity, increased residual volume).
