Diseases mimicking childhood asthma (differential diagnosis)

Upper airway diseases.

  • Allergic rhinitis and sinusitis.

  • Obstructions involving large airways.

  • Foreign body in trachea or bronchus.

  • Vocal cord dysfunction.

  • Vascular rings or laryngeal webs.

  • Laryngotracheomalacia, tracheal stenosis, or bronchostenosis.

  • Enlarged lymph nodes or tumor.

    Obstructions involving small airways.

  • Viral bronchiolitis or obliterative bronchiolitis.

  • Cystic fibrosis.

  • Bronchopulmonary dysplasia

    Recurrent cough not due to asthma.

  • Heart disease

  • Aspiration from swallowing mechanism dysfunction or gastroesophageal reflux.

  • Recent advances in diagnosis of childhood asthma:
    Impulse osillometery (IOS)

    Impulse Osillometry is a newer technology that uses small amplitude pressure oscillations to determine the resistance of the airway. Read More

    Exhaled Nitric Oxide test.

    NO is produced in discrete concentrations in the healthy human airway where it is important in physiological functions such as maintaining airway patency. NO is over produced in asthmatic individuals. It is responsible for airway inflammation (swelling) and is also the product of airway inflammation. Read more
