AIM: In Japan, @entity1151 ( @entity1151 ) is still rare, but the number of @entity1 with @entity1151 has been steadily increasing. It is important for early diagnosis and early management of @entity1151 to recognize epidemiological characteristics of this condition. METHODS: We investigated the epidemiological characteristics of 252 @entity1 with @entity1151 who were admitted to our institutions between 1975 and 2001. @entity1151 was more prevalent in @entity1 that in @entity1 . It was observed the most in the age group between 50s to 70s, especially in @entity1 . Many @entity1 had prolonged immobilization, recent major operation, @entity28 , or @entity5 , as risk factors for @entity1211 . One hundred and thirty-eight @entity1 developed @entity1151 in hospital; 60 @entity1 were in Department of Internal Medicine, 28 in General Surgery, 15 in Orthopedics, 15 in Obstetrics and Gynecology, and 20 in other services. RESULTS: Among 58 @entity1 with @entity5 , 43% had @entity5 in digestive organs, 21% in gynecological, and 17% in urological. Among 61 @entity1 who were examined for the presence of @entity49 , 13 @entity1 had inherited @entity49 (8 @entity7131 , 4 @entity4889 , and 1 @entity10647 ) 11 had antiphospholipid antibodies which indicated @entity49 . Five out of the above 61 @entity1 (8%) had no obvious risk factors including @entity49 . CONCLUSION: The findings in our @entity1 were almost the same as those in Western @entity1 , except for some points. These results might be useful to establish a preventive approach for @entity1151 in Japan.
