OBJECTIVE Metabolic syndrome (MetS) is a cluster of metabolic abnormalities with insulin resistance (IR) as a major component. It has been recently questioned whether MetS and its related components are associated with functional and morphological alterations of the thyroid gland. The aim of our study is to examine thyroid volume and nodule prevalence in a case-control study of patients with Me...

OBJECTIVE To evaluate the effect of case volume on the diagnostic yield and interpretation of thyroid fine-needle aspiration (FNA). DESIGN Retrospective case series. SETTING An academic tertiary referral center and 2 community hospital centers. PATIENTS Data were retrospectively reviewed for all consecutive patients undergoing thyroid FNA at these institutions during the 2009 calendar yea...

BACKGROUND Selenium (Se) is a necessary element for the biosynthesis of thyroid hormones. We investigated the relationship between selenium status, thyroid volume, and goiter in a cross-sectional study in an iodine-sufficient area. METHODS We selected residents of Chengdu (over 18 years old and living in the city for more than 5 years) using a stratified cluster sampling technique. Fifteen hu...

Objective: The thyroid gland is susceptible to the formation of nodules. Therefore, due to the critical role of selenium in the function of the thyroid gland, the impact of this element on the size and volume of this organ and its nodules were examined. Materials and Methods: During three months, two groups consisting of 30 patients with benign thyroid nodules who were referred to Baghaeipour ...

I131 is a famous radio-iodine isotope in use for diagnosis and treatment of hyper functioning and cancerous thyroid gland. It is a nuclear reactor product; however nuclear reactor may be unavailable in some areas. Replacement by I-124 may be possible, another iodine isotope producible by cyclotron; a system more available than reactor. Here absorbed fraction of Gamma and Beta rays of...

OBJECTIVE Chronic autoimmune thyroiditis (AT) is the most common cause of thyroid disease in children. The aim of the study was to define the epidemiological clinical and laboratory characteristics of children and adolescents with AT. DESIGN Various parameters including thyroid ultrasonography of 228 children and adolescents aged 10.2 ± 2.5 yrs (mean ± SD) with AT, who attended our Pediatric ...

OBJECTIVE The objective was to study the associations between serum selenium concentration and thyroid volume, as well as the association between serum selenium concentration and risk for an enlarged thyroid gland in an area with mild iodine deficiency before and after iodine fortification was introduced. Another objective was to examine the association between serum selenium concentration and ...

Marked changes in thyroid function occur during puberty as an adaptation to body and sexual development. Characteristics of thyroid growth were investigated in 259 healthy adolescents (110 girls and 149 boys), aged 11--17 yr, in an urban area of Switzerland with sufficient iodine supply. The thyroid volume determined by ultrasonography was correlated with chronological age, body weight, body he...

OBJECTIVE The objective of this study was to determine the measurement of normal range of ultrasound (US) thyroid gland dimensions in school-aged children (6-16 years) in our environment and compared with what is obtained elsewhere. SETTING AND DESIGN A prospective ultrasound measurement study done in University of Benin Teaching Hospital Benin, Nigeria. MATERIALS AND METHODS A prospective ...
