BACKGROUND AND OBJECTIVE Thyroid hormones have pronounced effects on the cardiovascular system. Thyrotoxicosis affects blood pressure (BP), modifying both diastolic (DBP) and systolic (SBP) pressures. There are no studies examining BP with ambulatory blood pressure monitoring (ABPM) in hyperthyroidism before and after control of thyroid function. Our aims(More)
22 patients with Grave's disease were followed up for up to a year after antithyroid drug therapy was discontinued. Clinical assessment and serum T3, T4, and thyroid-stimulating-hormone (T.S.H.) estimations were done serially and simultaneously. Serum T3 or T4 concentrations may be elevated briefly in the first few weeks after antithyroid drugs are stopped,(More)
OBJECTIVE We report a case of a primary urothelial carcinoma of the bulbomembranous urethra, with special emphasis on histopathological and immunohistochemical findings. METHODS/RESULTS A 63-year-old man presented urethral obstruction symptoms. A radical phalectomy was performed and a 4.5 x 4 cm bulbomembranous urethral tumor was observed.(More)
Seventeen patients with solitary autonomous nodules of the thyroid were studied. Eight had clinical features of hyperthyroidism though in some the clinical manifestations were mild. The serum T3 concentration was elevated in all patients with hyperthyroidism but the serum T4 and free thyroxine index were within the normal range in five. All patients with(More)
A rapid and precise radioimmunoassay (RIA) for serum total thyroxine (T4) on as little as 1-10 mul of unextracted serum is described. Results in hypothyroidism (overt and borderline), in euthyroid subjects in pregnant and oestrogen-medicated subjects, and in hyperthyroidism (overt and borderline) are compared with the results on the same sera by an(More)
