Study Notes
- Asthma is characterized by increased airway responsiveness, narrowing, thickening of airway walls, and inflammation with cells like eosinophils and mast cells releasing inflammatory mediators.
- Triggers for asthma include occupational sensitizers, non-specific factors like viral infections, cold air, and rare causes like Aspergillus fumagatus spores.
- Diagnosis of asthma is often based on history and response to bronchodilators, with lung function tests and allergy tests playing a role.
- Treatment for asthma involves controlling triggers, using bronchodilators, anti-inflammatory agents like steroids, leukotriene receptor antagonists, and immunosuppressive agents.
- Chronic obstructive pulmonary disease (COPD) is characterized by poorly reversible airflow limitation, inflammation, and is mainly caused by smoking in developed countries.
- COPD includes chronic bronchitis with airway inflammation and emphysema with lung tissue destruction, leading to symptoms like cough, sputum, and breathlessness.
- COPD diagnosis involves lung function tests, chest X-rays, arterial blood gases, and treatment includes smoking cessation, bronchodilators, corticosteroids, and management of complications like respiratory failure and cor pulmonale.
- Lung tumors, specifically primary bronchial carcinoma, are common with a poor prognosis, accounting for 95% of primary lung tumors.
