PURPOSE: To report the incidence and demographics of childhood @entity1736 diagnosed over a 40-year period in a well-defined population. DESIGN: Retrospective, population-based cohort study. @entity1 : @entity1 (<19 years) diagnosed with childhood @entity1736 and residents of Olmsted County, Minnesota, from January 1, 1965, through December 31, 2004. METHODS: The medical records of all potential @entity1 identified by the Rochester Epidemiology Project were reviewed. MAIN OUTCOME MEASURES: Calculated annual age- and gender-specific incidence rates and demographic information. RESULTS: A total of 107 @entity1 were diagnosed with @entity1736 during the 40-year period, yielding an incidence of 7.9 per 100000 younger than 19 years (95% confidence interval [CI], 6.4-9.5). Ninety-six (89.7%) of the 107 had @entity66 . Eighty-one (75%) of the 107 had simple @entity3065 , yielding a birth prevalence of 1 in 842 births. A family history of childhood @entity1736 was present in 12% of queried @entity1 with simple @entity3065 . Three (4%) of the simple @entity3065 cases were bilateral and 55 (68%) of the unilateral cases involved the @entity3066 (95% CI, 57%-78%; P<0.001). CONCLUSIONS: Childhood @entity1736 was diagnosed in 7.9 per 100000 @entity1 younger than 19 years (95% CI, 6.4-9.5). @entity3065 was the most prevalent form, occurring in 1 in 842 births, and was significantly more likely to involve the left side.
