    Study Notes

    Asthma

    • A chronic, reversible inflammatory disorder affecting the airways.
    • Characterized by increased sensitivity of the tracheobronchial tree to triggers.
    • Causes episodic narrowing and inflammation of airways.
    • Common symptoms include wheezing, shortness of breath, chest tightness, and coughing.
    • Severity can range from mild to severe.
    • All patients require a reliever medication (bronchodilator), often a short-acting β2 agonist (SABA).
    • Treatment is managed through steps (1-5) with escalating options.

    Asthma Triggers

    • Allergens
    • Infections
    • Exercise
    • Rapid changes in weather
    • Exposure to irritating substances (like tobacco smoke)

    Asthma Diagnosis

    • Based on exclusion of other conditions (differential diagnosis).
    • Requires episodic symptoms of airflow obstruction (e.g., wheezing, coughing, shortness of breath).
    • Crucial to show that airflow blockage is at least partially reversible with bronchodilators.

    Asthma Diagnosis Tools

    • Peak flow meters
    • Spirometry, measuring peak expiratory flow rate (PEFR) and forced expiratory volume in one second (FEV1).

    Non-Cardiac Chest Pain (additional information)

    • Recurrent substernal chest pressure or other chest discomfort, unrelated to the heart.
    • Potential causes include musculoskeletal, gastrointestinal, psychiatric, or pulmonary disorders.
    • First step: Rule out cardiac cause via thorough physical exam and diagnostics such as ECG, cardiac enzymes, stress test, or coronary angiography.
    • Important physical exam: Assess general appearance, vital signs (including pulse oximetry), check for lymphadenopathy, jugular venous distension (JVD), tracheal deviation, and inspect the thorax for rashes or trauma. Palpate and percuss the chest for pain and dullness. Auscultate lungs, heart, and abdomen for abnormal sounds.
    • Diagnostics: 12-lead ECG, cardiac enzymes, stress test, coronary angiography, empirical response to a proton pump inhibitor if GERD suspected (first-line GERD screen), chest X-ray, arterial blood gas (ABG) analysis, complete blood count with differential (CBC with diff).
    • Immediate referral: Indicate immediate emergency department or specialist referral for hemodynamic instability, suspected pulmonary embolism, pneumothorax, esophageal rupture, or aortic dissection.

    COPD

    • Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease characterized by airflow limitation.
    • Usually progressive, not fully reversible, and associated with an abnormal inflammatory response of the lungs.
    • Approximately 80% to 90% of COPD deaths are caused by smoking.
    • Diagnostics: Spirometry is the gold standard.
    • Diagnostics: Forced expiratory time
    • Diagnostic Criteria: Post-bronchodilator FEV1/FVC ratio of < 0.70.
    • Diagnostic Criteria: FEV1 < 80% predicted.
    • Other Diagnostics: Pulse oximetry, COPD assessment test, chest X-ray, blood gas measurements, sputum analysis.

    Asthma Management

    • Reliever Medications: Used as needed to treat symptoms
      • Include short-acting β2-agonist bronchodilators (SABAs).
      • May also include low-dose ICS/formoterol, and short-acting anticholinergics.
    • Controller Medications: Used daily to prevent symptoms and reduce inflammation
      • May include inhaled corticosteroids (ICS) and long-acting β-agonist bronchodilator combinations (ICS/LABA).
      • Add-on controller medications include long-acting anticholinergics, Anti-IgE, Anti-IL5, and systemic corticosteroids.

    Asthma Treatment Steps

    • Step 1: Reliever medication (SABA) as needed; Preferred controller: low-dose ICS
    • Step 2: Reliever medication (SABA); Preferred controller: low-dose ICS
    • Step 3: Reliever medication (SABA or low-dose ICS/formoterol); Preferred controller: low-dose ICS/LABA
    • Step 4: Reliever medication (SABA or low-dose ICS/formoterol); Preferred controller: medium/high-dose ICS/LABA
    • Step 5: Consultation

    Hemoptysis

    • Hemoptysis is the expectoration of blood, possibly mixed with mucus, from the lung parenchyma or tracheobronchial tree.
    • Ranges from small blood-streaked sputum (common in bronchitis) to massive hemorrhage (medical emergency).
    • Common causes include acute and chronic bronchitis, lung cancer, pneumonia, and tuberculosis.

    Hemoptysis Diagnosis

    • Diagnostics: Chest X-ray, CT scan, fiberoptic bronchoscopy (used in combination).
    • Diagnostics further include sputum testing, Mantoux testing, QuantiFERON gold, CBC, and renal function studies.

    Hemoptysis Management

    • Immediate referral for massive hemoptysis (>200 mL/day).
    • Outpatient treatment possible for low-risk patients with normal chest X-rays.
    • Treat the underlying cause, aiming to stop bleeding and prevent aspiration.

    Community-Acquired Pneumonia (CAP)

    • An acute infection of the pulmonary parenchyma, frequently associated with at least two symptoms of active infection in ambulatory patients.
    • Hospital-acquired pneumonia (HAP): Pneumonia occurring ≥48 hours after admission, not incubating at the time of admission.
    • Ventilation-associated pneumonia (VAP): Pneumonia >48 hours after endotracheal intubation. Health care–associated pneumonia (HCAP):
    • Symptoms include fever, chills, rigors, malaise, cough (with or without sputum).

    CAP Diagnosis

    • Diagnostics: Chest X-ray (gold standard); pulse oximetry; sputum analysis; gas exchange by telemetry or arterial sampling; CBC with differential, chemistry panel, LFTs, two sets of blood cultures.

    CAP Management

    • Initial assessment: Determine outpatient vs. inpatient treatment.
    • Severity assessment: Use a validated tool.
    • Pharmacotherapy:
      • Low-risk patients: Macrolide antibiotic recommended. Doxycycline as secondary option.
      • Patients with comorbidities: Respiratory fluoroquinolone or β-lactam plus macrolide recommended.
    • Antivirals: Consider in appropriate circumstances.
    • Vaccination: Pneumococcal vaccination recommended.

    Lung Cancer

    • Lung cancer (bronchogenic carcinoma) involves multiple malignancies of the lung or airways, categorized as non-small cell (NSCLC) or small-cell (SCLC) lung cancer.
    • Diagnostics: Chest X-ray, CT scan, biopsy.
      • Brain imaging (MRI) may also be needed.
    • Management: Referral to oncology, pulmonology, thoracic surgery.
      • Surgery.
      • Chemoradiation.
      • Targeted therapy.
      • Palliative care/supportive care.
      • Immunotherapy.

    Pleural Effusion

    • Pathological accumulation of fluid within the pleural space.
    • Diagnostics: Chest X-ray, CT scan, Elevated WBC count.
      • PET scan for malignant pleural effusion.
      • Thoracentesis and pleural fluid analysis.
    • Management: Treat underlying disease.
      • Co-management with pulmonologist/specialist recommended.
      • Symptomatic treatment for comfort. Hospital admission for significant respiratory compromise.

    Pleurisy

    • Inflammation of the pleura, characterized by the rubbing together of pleural layers, causing painful symptoms.
    • A symptom, not a diagnosis, resulting from various underlying conditions.
    • Diagnostics: Chest X-ray, thoracentesis, CT scan, Ventilation/perfusion scan
    • Management: Treat the underlying cause. NSAIDs for pain management.

    Pneumothorax

    • Pneumothorax is the presence of air in the pleural space, reducing negative intrathoracic pressure, which impacts ventilation and oxygenation.
    • Causes include idiopathic, trauma, or iatrogenic.
    • Symptoms: Acute breathlessness and unilateral pleuritic chest pain.
    • Diagnostics: Chest X-ray, ultrasound, CT scan (gold standard).
    • Diagnostics: Pulse oximetry, blood gas analysis.
    • Management: Varies by type, size, and contributing factor.
      • Observation, needle aspiration, chest tubes (including pleurodesis, thoracotomy, or sternotomy).
    • Referral: Immediate emergency department referral for respiratory compromise.

    Pulmonary Embolism (PE)

    • Obstruction of pulmonary arteries by emboli (thrombus, tumor, fat, air, amniotic fluid, parasites).
    • Most common cause: Thrombus from pelvis or legs.
    • Diagnostics: Patient history, physical exam, ABGs, troponin, D-dimer, serum dimer, ECG, chest X-ray, CT angiography (gold standard, replacing V/Q scan). Spiral CT is usually used due to cost and availability.
    • Management: Stabilization and oxygenation, pulse oximetry, IV fluids. Anticoagulation (low-molecular-weight heparin). Surgical embolectomy. Fibrinolytics. Immediate referral for all suspected PE cases.

    Pulmonary Hypertension (PH)

    • Pulmonary hypertension (PH) occurs as a common end point for several disease processes in which increased pulmonary vascular resistance results in increased right-sided heart pressure.
    • 5 Types of PH:
      • Group 1 (PAH): Adverse remodeling of small pulmonary arteries.
      • Group 2: Associated with increased left-sided heart pressure.
      • Group 3: Associated with chronic lung disease (sleep apnea most common).
      • Group 4 (CTEPH): Caused by multiple pulmonary emboli.
      • Group 5: Heterogeneous collection of systemic diseases (hematologic, inflammatory, metabolic).
    • Management:
      • Treatment based on causative factor.
      • Pharmacotherapy: Vasodilators (calcium channel blockers, prostanoids, endothelin receptor antagonists, or phosphodiesterase inhibitors), diuretics.
      • Surgery: Possible
      • Other: Physical exercise, weight loss, nutrition.

    Sarcoidosis

    • Sarcoidosis is a multisystem, inflammatory, granulomatous process that commonly affects young and middle-aged adults.
    • Can present in acute, subacute, or chronic form
    • Usually discovered asymptomatically with abnormal chest X-ray
    • Nonspecific pulmonary symptoms—Dry cough, dyspnea, chest pain, fever, fatigue, anorexia, weight loss, and, occasionally, chills and night sweats
    • Referral is indicated for all suspected cases of sarcoidosis.
