Purpose: Endocardial involvement documented by echocardiography is a major criterion of the modified Duke criteria (MDC) for infective endocarditis (IE). Though transesophageal echocardiography (TEE) is sensitive in the diagnosis of IE, it can be inappropriately used.
Methods: This retrospective study included all patients who underwent TEE due to bacteremia, fever, and/or endocarditis in a single, tertiary academic medical center in 2013.
Objective: To report a case of a patient with Graves disease presenting with agranulocytosis induced by methimazole, with subsequent thyroid storm and successful therapeutic use of plasmapheresis.
Methods: The clinical features and laboratory findings in a patient with agranulocytosis and thyroid storm are presented, and the available literature on utilization of plasmapheresis in the setting of thyrotoxicosis is reviewed.
Results: A 40-year-old Vietnamese woman with Graves disease was admitted with methimazole-induced agranulocytosis.
