Sulfasalazine as a cause of false-positive elevation of urinary normetanephrine in patients with adrenal mass and suspected phaeochromocytoma: a diagnostic challenge.

In patients with suspected phaeochromocytoma, biochemical screening of urine or blood for excess secretion catecholamines and/or their metabolites is performed. Elevated levels of catecholamines and metanephrines help in establishing the diagnosis of phaeochromocytoma. In two patients with adrenal lesions who were subjected to biochemical testing significantly elevated urinary normetanephrines appeared to establish the diagnosis of phaeochromocytoma.

Left Ventricular Thrombus After Primary PCI for ST-Elevation Myocardial Infarction: 1-Year Clinical Outcomes.

Background: Left ventricular thrombus formation is a complication of acute myocardial infarction. However, the incidence and risk of systemic thromboembolism in the era of primary angioplasty for ST elevation myocardial infarction (STEMI) is unclear. This study aims to determine clinical outcomes in patients with STEMI treated with primary angioplasty and left ventricular thrombus at 1 year.
