To evaluate the importance of trace amounts of elements in thyroid cancer etiology and diagnostics, instrumental neutron activation analysis has been used to estimate Ag, Co, Cr, Fe, Hg, I,Rb, Sb, Sc, Se, and Zn concentrations in malignant and benign thyroid nodules as well as in apparently intact paranodular thyroid tissue. Resected material from 135 patients was obtained from operations. Fort...

conclusions no significant variance was observed among patients underwent for cardiac catheterization, stemi, nstemi, unstable angina, and atrial fibrillation with respect to ft4, ft3, and tsh levels during coronary care unit hospitalization based on their profile data. results excluding those taking thyroid hormone preparations, 76.7% of patients admitted with acute coronary heart disease (st-...

Background: Due to its use of ionising radiation, the field of nuclear medicine is a unique and significant part of medical diagnostics and patient treatment. The aim of this study was to assess the internal exposure of nuclear medicine employees to radioiodine 131I and technetium 99mTc as well as to assess the external exposure doses. Material and Methods: The radioiodine 131I and technetiu...

Purpose Our aim was to analyze NAMPT expression in thyroid tissue derived from patients with Graves' disease with (GD) and without (GO) orbitopathy, patients with toxic nodular goiters (TNG) and thyroid cancers (TC), and healthy controls. Methods 153 thyroid tissue samples of consecutive patients who underwent thyroidectomy were collected. Previous therapy with steroids was an exclusion crite...

The obese strain (OS) of chickens, which suffers from spontaneous autoimmune thyroiditis, is an excellent animal model for Hashimoto's thyroiditis and provides a unique opportunity to investigate the mechanisms underlying and driving the onset of the disease. Following recent advances in cloning chicken cytokines, we can now begin to investigate the role of cytokines in driving the lymphoid inf...

A population of newts from a pond near Crail, Fife, was found to contain neotenic and goitrous specimens of Triturus helveticus in 1951 and 1952 but not in 1953 and 1954. This is a unique record of goitre among amphibians. The thyroid glands of normal adult and neotenic non-goitrous T. helveticus are paired spheroidal or ellipsoidal bodies whose longest dimension varies between 300 and 700 fi. ...

Cowden's disease, or multiple hamartoma syndrome, is an autosomal dominant genodermatosis, characterized by the presence of multiple cutaneous hamartomas, oral fibromas and benign acral keratosis. It affects multiple organs (breast, thyroids, stomach, colon), with the strong possibility of malignant neoplasia developing in these organs. We present a case of this rare syndrome, highlighting the ...

Mediastinal ectopic thyroid is a very rare condition, with few reported cases in the literature and no reported cases in Korea. This report describes an asymptomatic 65-year-old man with a right paratracheal mass compressing the superior vena. Additionally, the epidemiology, clinical manifestation, diagnosis, and management of mediastinal ectopic thyroids are discussed. A mediastinal ectopic th...
