we conclude that in this setting : ( 1 ) fiberoptic bronchoscopy is an extremely sensitive procedure for diagnosing pulmonary infections , ( 2 ) bronchial brushings are as useful as transbronchial biopsies for diagnosing nonfungal infections , ( 3 ) these procedures are less useful for diagnosing noninfectious conditions , and ( 4 ) in the face of a negative bronchoscopic procedure , there is a very low probability that an infectious process will be found with an open biopsy .
