Study Notes
Asthma
- USMLE Qs may present patients with a history of smoking or alcohol use. Early-onset emphysema and cirrhosis can be associated with these behaviors. Typically COPD requires greater than 20+ years of smoking.
- Bronchospasm can be idiopathic, hereditary, or triggered by allergens or cold air.
- Cough-variant asthma presents primarily with a dry cough, often worse in winter. This is present in one-third of asthma patients.
- Atopy constellation can include dry cough in winter, seasonal allergies (seasonal allergic rhinitis and/or conjunctivitis), urticaria or skin rashes, and/or eczema, which can co-occur with asthma.
- Aspirin-induced asthma is caused by aspirin inhibiting COX, leading to increased leukotrienes which result in bronchoconstriction.
- Samter triad encompasses aspirin allergy, asthma, and nasal polyps.
- Increased expiratory phase is a common term in asthma vignettes characterized by an increased time for exhalation. This is seen in obstructive lung diseases.
- Acute asthma causes decreased COâ‚‚, increased pH, and unchanged bicarbonate, leading to respiratory alkalosis. This is because COâ‚‚ diffuses quickly.
- Transition to type II respiratory failure in acute asthma may occur when COâ‚‚ and pH rebound to normal levels despite low Oâ‚‚. This signifies a transition towards hypoventilation.
- Spirometry is the best initial step in diagnosing asthma in a patient experiencing acute episodes. The expiratory curve is concave in asthma.
- Methacholine challenge can also diagnose asthma. This muscarinic agonist is given to trigger bronchoconstriction and symptoms. It is not given during an acute asthma attack.
- Initial outpatient asthma management includes β2-agonists (like albuterol) for acute attacks, and inhaled corticosteroids for chronic, weekly or more episodes.
- Management for severe asthma attacks involves nebulized albuterol, oxygen, and intravenous methylprednisolone in a hospital setting. Inhaled corticosteroids should be administered at discharge if the patient is not currently on them. A specific USMLE Q will state this.
- Inhaled fluticasone may be initiated at discharge, regardless of current therapy, for hospitalised and chronic patients.
Bronchiectasis
- A common cause worldwide is tuberculosis (TB), and in western countries it is cystic fibrosis (CF), and occasionally, smoking.
- Presentation often involves a large volume of foul-smelling (anaerobic) sputum.
- Clubbing of the fingers is not mandatory, but USMLE frequently associates it with bronchiectasis.
- A 2CK Q may present a child with right middle lobe syndrome, scant white sputum, and a linear opacity, where bronchiectasis would be the answer
