The American Academy of Pediatrics acute sinusitis guideline was too complex for limerickification, and even resisted sonnet format, so here it is in iambic pentameter.
Nasal discharge’s mostly allergic or viral
And thus needs only symptomatic care
With no need for an antimicrobial trial
Unless high-risk and flu virus is there.
Only think sinusitis as a cause
In three scenarios based on the patient’s tale
Note none involve a mucus color clause
So green snot counts not–neither dark nor pale.
First, symptoms exceed 10 days and don’t improve
Or second, improve but then thereafter worsen
(‘Tho this usually means that in has moved
A second virus attacking the same poor person).
Third is when the onset is severe
With fever 39 degrees or higher
And nasal discharge purulent not clear
Both unrelenting for three days required.
For children meeting persistent criteria
Consider observing three days more
And, weighing risks such as diarrhea,
Start antibiotics only if symptoms endure.
