Changing pattern of paediatric XXXX in northern Stockholm 1990-2001.

@entity1 @entity31 @entity29 @entity1960 @entity792 @entity30
BACKGROUND: An increased incidence of paediatric @entity30 was reported recently by our group. AIMS: To assess the incidence and characteristics of @entity29 ( @entity29 ) in northern Stockholm between 1990 and 2001. METHODS: All records of individuals 0-15 years of age with suspected @entity29 in the population based catchment area of 180000 individuals were scrutinised using defined diagnostic criteria. @entity1 files were searched for relatives with @entity29 , and for concomitant @entity792 . RESULTS: A total of 152 @entity1 were diagnosed with @entity29 , corresponding to an overall incidence (per 100000) of @entity29 of 7.4. The incidence of @entity30 ( @entity30 ) was 4.9, @entity31 ( @entity31 ) 2.2, and indeterminate @entity1960 0.2. Between 1990 and 2001, there was a marked increase in the incidence of @entity30 while the incidence of @entity31 was almost unchanged, leading to a net increase in the overall occurrence of @entity29 . There was a male dominance of @entity30 . Fourteen per cent and 11% of @entity1 with @entity30 and @entity31 , respectively, had a first or second degree relative with @entity29 . Eighteen per cent and 10% of @entity1 with @entity30 and @entity31 , respectively, had a concomitant @entity792 . Ten @entity1 with @entity30 (10%) underwent surgery. CONCLUSIONS: The incidence of @entity30 has increased in northern Stockholm. The current incidence is higher than that reported from other areas. Our results suggest a shift in presentation and diagnosis from @entity31 towards @entity30 , but also a net increase in @entity29 . Concomitant @entity792 and family history are common in paediatric @entity29 .
