Study Notes
Introduction to Respiratory Medicine
- Objectives include understanding respiratory anatomy, physiology, symptoms, investigations, and common conditions.
Terminology
- Pneumo: Refers to air
- Thorax: The chest area
- -itis: Indicates inflammation
- Mortality: Refers to death rates
- Morbidity: Indicates illness rates
Respiratory Disease in the UK
- Affects 1 in 5 individuals, ranking as the 3rd leading cause of death.
- Major conditions include lung cancer and chronic obstructive pulmonary disease (COPD).
- Increased prevalence during winter months.
- Financial burden on NHS: Asthma (£3 billion), COPD (£1.9 billion), total respiratory conditions (£11 billion).
- Mortality rates disproportionately high in disadvantaged populations due to factors like smoking, air pollution, and poor housing.
Common Symptoms and Signs
- Breathlessness, cough (productive or dry), wheeze, cyanosis (blue coloration due to low oxygen), and nasal congestion.
- Symptoms can indicate various conditions:
- Stridor suggests obstruction.
- Wheeze may indicate asthma or COPD.
- Dry cough is often associated with fibrosis, while a productive cough can indicate pneumonia.
Respiratory Investigations
- Blood tests can detect infection or eosinophilia, related to asthma/allergy.
- Chest X-ray (CXR) used for assessing conditions like infections, cancer, and fibrosis.
- CT scans utilized for pulmonary embolisms (PE), complex infections, and cancers.
- Peak flow measurements for asthma; spirometry for COPD and other conditions.
- Sleep studies assess obstructive sleep apnea.
Asthma
- Characterized by chronic airway inflammation, hyper-responsiveness, and reversible symptoms.
- Common triggers include pollutants, allergens, and respiratory infections.
- Key symptoms: wheeze, nocturnal cough, breathlessness, and association with eczema and hayfever.
- Management includes inhalers, peak flow monitoring, smoking cessation, avoiding triggers, and regular reviews.
Chronic Obstructive Pulmonary Disease (COPD)
- Comprises emphysema and chronic bronchitis, defined by a 3-month productive cough lasting over 2 years.
- Primarily smoking-related, with significant impacts on healthcare resources.
- Symptoms include progressive breathlessness, chronic cough, and wheeze.
- Investigations focus on CXR, spirometry, and patient history.
Bronchiectasis
- Defined by irreversible bronchial dilation, leading to chronic cough and recurrent infections.
- Caused by idiopathic factors, post-infection conditions, or poorly controlled asthma.
- Signs include productive cough and possible haemoptysis; investigations involve CXR and sputum cultures.
Pneumothorax
- Occurs when air enters the pleural space, potentially causing lung collapse.
- Types include primary (occurring in healthy lungs) and secondary (associated with existing lung diseases).
- Symptoms include sudden breathlessness and pleuritic pain. Investigations often include CXR.
Fibrosis
- Involves lung scarring, leading to restrictive lung disease, with idiopathic pulmonary fibrosis being the most common form.
- Associated with occupational exposures and certain autoimmune conditions.
- Investigations include clubbing, crepitations, and imaging (CXR, HRCT).
Lung Cancer
- The most common cancer in the UK with a poor prognosis, often diagnosed late.
- Risk factors primarily include smoking and occupational exposures.
- Key symptoms involve weight loss, persistent cough, haemoptysis, and possible pleural effusions.
Pulmonary Embolism (PE)
- Refers to blood clots in the pulmonary artery, often related to immobility, surgery, or cancer.
- Symptoms include sudden breathlessness, pleuritic chest pain, and hypoxia. Diagnosis may involve ECG, CXR, and D-dimer levels.
Management and Differential Diagnosis
- Proper management includes anticoagulation for PE and targeted therapies for lung cancer.
- Always consider differential diagnoses based on presenting symptoms and historical context.
- Utilize investigations thoughtfully while maintaining a straightforward approach to diagnosis. Common conditions should guide clinical reasoning.
