Objective: Metabolic syndrome 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 metabolic syndrome. Design: 114 newly diagnosed euthyroid patients with Met S were randomly matched for age and gender with 123 subjects withou...

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 i-124 thro...

As we know breast cancer is the second death reason in Iran. One step of treatment process is radiotherapy, which needs careful consideration of contouring and therapeutic techniques Lung, thyroid, spinal cord, trachea and humerus are sensitive organs in breast cancer radiation therapy.  The most clinical studies recommended two ways for delivering 95 percent of dose to supraclavicular and ...

PURPOSE We investigated the prevalence of hypothyroidism (HT) in patients with breast cancer who received radiation therapy to the supraclavicular (SC) field to evaluate the effect of radiation on thyroid. METHODS Between April 2007 and May 2016, consecutive patients with invasive breast cancer who received SC radiation were recruited. Thyroid-stimulating hormone (TSH) and free thyroxine (fT4...

Objectives. Assess the prevalence of thyroid nodules and predictors of malignant origin in patients with autoimmune thyroid diseases. Patients and Methods. Retrospective study including 275 patients, 198 with Graves' disease and 77 with Hashimoto's thyroiditis. Clinical and demographical data, ultrasonographical nodule characteristics, total thyroid volume and histological characteristics were ...

Background: The thyroid gland absorbs nearly all the iodine in the blood, independently of its isotopic composition. When a large enough activity of radioactive iodine like 131I, 132I, 133I is taken into the body, it can destroy the healthy thyroid gland cells as well as the cancer’s cells. In fact, as it is well known, some isotopes of iodine are used not only for acquiring thyroid image...

UNLABELLED Thyroid gland morphology is affected in patients with chronic kidney disease. THE AIM The purpose of this study was to compare thyroid gland morphology among patients on chronic hemodialysis (HD) and healthy participants and to assess the duration of dialysis on thyroid disorders. MATERIAL AND METHODS Prospective study included 80 participants divided into two groups. Study group...

OBJECTIVE The determination of goiter prevalence in children by thyroid ultrasound is an important tool for assessing iodine deficiency disorders. The current World Health Organization/International Council for the Control of Iodine Deficiency Disorders (WHO/ICCIDD) normative values, based on thyroid volume in iodine-sufficient European children, have recently been questioned, as thyroid volume...

Radiation induced thyroid dysfunction is usually underestimated in patients with breast cancer who had supraclavicular irradiation (RT). In the present study, a total of 28 patients with breast cancer received supraclavicular RT were evaluated focusing on radiation dose-volume factors in relation to thyroid function. Thyroid function tests, including serum thyroid stimulating hormone, free thyr...

Endemic iodine deficiency is largely an environmental problem affecting whole populations. Currently, thyroid volume data from a population are analyzed with the sole objective of obtaining an estimate of goitre prevalence using +97th percentile or +2 standard deviations of an appropriate reference as cut-off. This paper proposes an alternative approach to the analysis and presentation of thyro...
