The purpose of this study is to determine the relationship between dexamethosone (steroid)
and children's sleep and fatigue.
Approximately 134 children and adolescents will be enrolled. All children and adolescents
will wear a wrist actigraph for two consecutive 5-day study periods. Children and
adolescents will have blood drawn 2 times on Day 1 when they are on dexamethosone. Their
parents will complete a sleep diary and fatigue questionnaire by telephone on Days 2 and 5
