Picmonic
Croup is a general term that describes a group of conditions characterized by edema and inflammation of the upper airway. The focus of this Picmonic is on the most common croup disorder - laryngotracheobronchitis, often abbreviated as LTB, which often leads to hospitalization. The other group disorders are acute epiglottitis, acute spasmodic laryngitis, and acute tracheitis.
