Age affects the prognostic impact of diabetes in chronic heart failure.

Aims: Increasing age is an established prognostic determinant in chronic heart failure (HF). Diabetes often complicates HF in its course and appears to worsen HF prognosis. A differential impact of diabetes depending on patients' age was not yet studied.

Graves' disease in a mediastinal mass presenting after total thyroidectomy for nontoxic multinodular goiter: a case report.

Background: Thyrotoxicosis after total thyroidectomy is mostly iatrogenic. Rarely, a hyperfunctional thyroid remnant or ectopic tissue may be the cause. There are few cases of Graves' disease arising from thyroid tissue located in the mediastinum and none in which Graves' disease was diagnosed only after surgery.
