Recent immigration trends have resulted in an increased prevalence of amebic @entity99 in southern states and in many northern American cities. Because amebic @entity99 generally do not require drainage, differentiation from pyogenic @entity99 is important. We, therefore, reviewed the records of @entity1 admitted to the UCLA Medical Center from 1968 through 1983 to compare the clinical manifestations and to access the results of treatment of @entity99 . During this 15 year period, 82 @entity1 (42 pyogenic and 40 amebic) with @entity99 were admitted. Factors which distinguished @entity1 with pyogenic abscesses included: age greater than 50 years; @entity1087 ; @entity111 ; @entity295 and @entity1457 ; a palpable mass; elevated @entity648 level; elevated alkaline phosphatase level, and abnormal abdominal roentgenograms. @entity1 with @entity9111 were more likely to have Mexican ancestry, recently traveled to an endemic area, @entity490 , @entity294 , abdominal tenderness, @entity382 and positive amebic serology. Hepatic scans and ultrasonography were excellent methods of detecting the presence of but not the type of @entity99 . Over-all, the mortality was 40 per cent for @entity1 with pyogenic abscesses whereas all 40 of the @entity1 with an amebic abscess survived. However, operative mortality was only 4.5 per cent for the 22 @entity1 with @entity867 who were managed with systemic antibiotics and surgical drainage. We conclude that many clinical and laboratory parameters can aid in the differentiation and, as a result, management of @entity1 with @entity99 .
