A child presents to your clinic with chronic cough.
Challenge: What is your presumptive diagnosis for the following presentations?
1) A staccato cough in young infants?
2) A "seal barking" or "brassy" cough?
3) A chronic paroxysmal cough triggered by exercise, cold air, sleep, or allergens in a kid with a rash?
4) A "Canadian goose-like" honking cough that disappears at night?
5) An acute or subacute paroxysmal cough...with an inspiratory whoop?
