Prognostic value of serum cardiac troponin I and T in chronic dialysis patients: a 1-year outcomes analysis.

To determine the incidence and prognostic value of increased serum cardiac troponin I and T concentrations over 12 months in chronic hemodialysis patients, we performed a retrospective chart review in 16 patients undergoing chronic renal hemodialysis randomly selected from the Regional Kidney Disease Program without prior knowledge of their cardiac status. Serum markers of myocardial injury (cardiac troponin I [cTnI], cardiac troponin T [cTnT], and creatine kinase MB [CK-MB]) were measured and clinical outcomes were assessed. At the beginning of the study, 12 of 16 (75%) patients had increased serum enzyme-linked immunosorbent assay (ELISA) cTnT concentrations greater than 0.

A case of mediastinal teratoma with CT and MRI correlation.

A case of mediastinal teratoma is described with emphasis on its magnetic resonance aspect. All the components of the mass were well defined. The major interest of magnetic resonance imaging in this case consisted in the good delineation of the pericardium and visualization of the absence of pericardial invasion.
