A population-based study of XXXX in Oregon, 1979-1982.

@entity1 @entity66 @entity294 @entity177 @entity1381
The authors conducted a retrospective hospital-based chart review of cases of @entity1381 among @entity1 less than or equal to 18 years of age, hospitalized in Oregon during the four-year period from January 1979 to December 1982. Thirty @entity1 with @entity1381 living in Oregon were hospitalized during this period, for an average annual incidence of 0.97 cases per 100,000 @entity1 . Seventy per cent of cases occurred in @entity1 under five years of age, for an incidence of 2.65 cases per 100,000 @entity1 . Twenty-seven (90%) of the 30 @entity1 were white, and 17 (57%) were female. Twenty-four (80%) had a diarrheal prodromal illness including 20 who had bloody @entity294 . Twelve @entity1 (40%) acutely required peritoneal dialysis, and two (7%) developed @entity177 . Three @entity1 died, for a case fatality ratio of 10%. Sixty per cent of the 30 cases occurred during the summer and early fall months. Geographic clustering was also evident. @entity1381 is a rare but @entity66 in Oregon and may occur in small clusters. Although descriptions of several large series of @entity1 have been published, this study describes the first statewide population-based study of this syndrome.
