Comparative StudySensitivity and specificity of the semiquantitative latex agglutination D-dimer assay for the diagnosis of acute pulmonary embolism as defined by computed tomographic angiography.
To determine the sensitivity and specificity of the semiquantitative latex agglutination plasma fibrin D-dimer assay for the diagnosis of acute pulmonary embolism by using computed tomographic (CT) angiography as the diagnostic reference standard. ⋯ The semiquantitative latex agglutination plasma fibrin D-dimer assay had moderate sensitivity and low specificity for the diagnosis of acute pulmonary embolism. When used alone, the results of this test were insufficient to exclude this serious and potentially fatal disorder. Approximately two thirds of our patients had positive D-dimer assays and required further evaluation to exclude acute pulmonary embolism.

Case ReportsGlomus tumor of the trachea: value of multidetector computed tomographic virtual bronchoscopy.
Glomus tumor of the trachea is extremely rare. We report a case of tracheal glomus tumor in a 39-year-old man who presented with hemoptysis. The diagnosis was made after bronchoscopic biopsy of a tumor involving the posterior wall of the upper trachea. ⋯ Tracheal sleeve resection with reconstruction was successful, and pathological studies confirmed complete resection and the diagnosis of glomus tumor. The patient was disease-free 3 months postoperatively. To our knowledge, this is the first reported case in which additional computed postprocessing was used to help evaluate the extent of such a tumor.
