DSM-IV-TR Casebook Diagnosis of "Baby Susan"
Susan was admitted to the hospital at age 6 months
by an aunt for evaluation of failure to gain weight. She had been
born into an impoverished family after an unplanned, uncomplicated
pregnancy. During the first 4 months of her life, she gained weight
steadily. Regurgitation was noted during the fifth month and increased
in severity to the point where she was regurgitating after every
feeding. After each feeding, Susan would engage in one of two behaviors:
1) she would open her mouth, elevate her tongue, and rapidly thrust
it back and forward, after which milk would appear at the back of
her mouth and slowly trickle out; or 2) she would vigorously suck
her thumb and place fingers in her mouth, following which milk would
slowly flow out of the corner of her mouth.
