Epidemiological findings in a XXXX cluster in western Missouri.

@entity1 @entity1313 @entity5 @entity75 @entity542 @entity1573 @entity463
A cluster of seven primary @entity1313 was identified in a town of 3000 population during the 10-year period from 1973 to 1982. With six deaths, this represents an age-adjusted mortality rate 4.1 times greater than expected. No other @entity5 were found to be in excess of the anticipated incidence in this town. When @entity1313 mortality rates in 36 other towns of approximately the same population were calculated, only one other town was found to have an excessive rate. All seven @entity5 in this study were histologically verified: six were diagnosed as @entity463 multiforme. Interviews were conducted with @entity1 or next-of-kin to obtain the exposure histories of the @entity1 . A number of respondents reported occupational or residential exposure either to a shoe factory or to one of the several @entity1573 hatcheries in the town. Many of the @entity1 ate fish from local ponds that had previously been used as coal mining strip pits. Two @entity1 were siblings. None of the @entity1 had a history of significant @entity542 . This unique situation may provide an opportunity to learn more about environmental risk factors for @entity75 . Further epidemiological studies are planned.
