In a review of a large number of @entity1 with @entity29 , @entity1778 was observed in five @entity1 with chronic @entity31 and in two @entity1 with @entity30 . In @entity31 @entity1 , there were three cases of @entity3052 and one case each of @entity981 and @entity1860 . In @entity30 @entity1 , there was one case each of @entity1860 and @entity1072 associated with @entity1148 . Sixteen other cases of @entity1778 have been reported to date in @entity29 . All @entity1778 , but particularly @entity3052 , have been described. There has been no single common feature as to type (whether @entity31 or @entity30 ), extent and course, or medical and surgical treatment of the @entity29 . The relative risk of @entity1778 in @entity1 with @entity31 was 5.3 [95% confidence interval 1.7 to 12.3 (P less than 0.01)] and of @entity3052 11.4 [95% confidence interval 2.3 to 24.9 (P less than 0.01)]. Our data on @entity1 with @entity30 were not sufficient to assess the statistical significance of @entity1778 in this disease. This study suggests that there may be an increased risk of @entity1778 , particularly @entity3052 , in @entity31 . The causal relationship, if any, remains undetermined.
