Role of bronchoalveolar lavage in the diagnosis of XXXX .

Fat @entity887 (FES) is a serious clinical disorder occurring in @entity130 @entity1 . The diagnosis of @entity7123 may be difficult to establish clinically. We therefore wanted to investigate the usefulness of bronchoalveolar lavage (BAL) in the diagnostic evaluation of @entity7123 . We analysed the presence of fat droplets in BAL cells in 32 @entity130 @entity1 (7 with full diagnostic criteria of @entity7123 , 17 with incomplete diagnostic criteria, and 8 with no diagnostic criteria at the time of bronchoscopy), 9 nontrauma @entity1 with @entity1576 and @entity358 , and a control group composed of 10 individuals. An increased percentage of oil red O positive alveolar macrophages (cut-off point > 3%) in BAL was found in 6 out of 7 @entity1 with definite clinical criteria of @entity7123 , and in 6 out of 20 @entity130 @entity1 without the clinical diagnosis of @entity7123 . In two @entity1 with @entity7123 , sequential BAL showed that the percentage of positive macrophages decreased when the clinical @entity10631 disappeared. An increased number of BAL macrophages with fat droplets was also observed in two @entity130 @entity1 without evidence of @entity7123 after long-bone surgical intervention. By contrast, all non- @entity130 @entity1 had a percentage of positive cells lower than 3%. Our findings suggest that BAL oil red O positive macrophages are frequently observed in @entity130 @entity1 irrespective of the presence of @entity7123 . Conceivably, a high number of oil red O positive macrophages could reflect clinically silent fat embolization.
