Pharmacologic treatment of severe skin-picking behaviors in Prader-Willi syndrome. Two case reports.
BACKGROUND
Prader-Willi syndrome (PWS) is characterized by hypotonia at birth, hypogonadism, early childhood obesity, and mental deficiency. Other behavioral symptoms that become prominent during adolescence and adulthood include temper outbursts, stealing and hoarding food, and skin picking. The self-excoriating skin picking behavior observed in individuals with PWS is quite common and can lead to persistent sores and infections, even requiring hospitalization.


METHODS
Two patients with PWS who displayed repetitive, self-mutilatory behavior of skin picking are described. They were both treated successfully with different doses of fluoxetine, a selective serotonin reuptake inhibitor.


CONCLUSIONS
The skin-picking behavior in patients with PWS may be a variant of the spectrum of obsessive-compulsive disorders. Obsessive-compulsive disorders have been successfully treated with serotonin reuptake inhibitors such as fluoxetine. Thus, fluoxetine may be considered an option in the management of skin-picking behavior in patients with PWS.
