Dr. Weyland examined a six month old infant that had been admitted to the University
Hospital earlier in the day. The baby's parents had brought young Zoey to the emergency
room because she had been suffering from a chronic cough. In addition, they said that
Zoey sometimes would "wheeze" a lot more than they thought was normal for a child with
a cold. Upon arriving at the emergency room, the attending pediatrician noted that salt
crystals were present on Zoey's skin and called Dr. Weyland, a pediatric pulmonologist.
Dr. Weyland suspects that baby Zoey may be suffering from cystic fibrosis.
