Quality of life after coronary artery bypass surgery

This study assessed the quality of life (QoL) of 124 people with coronary artery disease who had coronary artery bypass surgery in a hospital in Brazil, by using the Modified Flanagan`s QoL instrument as the outcome measure. In addition, we studied the association between QoL and demographic, clinical, and perceived health status (using SF-36 Health Survey) measures. The mean for the Modified Flanagan`s QoL was high (M = 84.8, SD = 13.6) when compared to similar studies in the United States. In a linear regression analysis, the SF-36 subscales of vitality, and general and mental health were statistically significant (p < .01 for all), after adjusting for other demographic and clinical variables. Increasing values of those SF-36 subscales corresponded to increasing Modified Flanagan`s QoL. Despite the limitations of the study, this result suggests that future clinical interventions aimed to improve QoL in this population could focus on the patient`s psychological conditions after the surgery.

Clear cell sarcoma of the mediastinum

A 59-year-old woman presented with a large mediastinal mass. At thoracotomy, the mass was found tightly adherent to the esophageal wall and right lower lobe of the lung. Histological examination showed a solid tumor composed of closely packed nests of cells with clear and eosinophilic cytoplasm, which were strongly and diffusely positive for S 100 protein but negative for HMB45 and Melan-A. The diagnosis of clear cell sarcoma was supported by demonstrating the presence of an EWS gene rearrangement by fluorescence in situ hybridization. There was no evidence that this lesion represented metastatic disease. To the best of our knowledge, primary mediastinal clear cell sarcoma has not been previously reported in the literature. We present the case and discuss the differential diagnosis. (C) 2009 Elsevier Inc. All rights reserved.
