Background. Subacute thyroiditis is a rare inflammatory thyroid disease presumably associated with viral infection, including COVID-19. It accounts for about 5% of all diseases.
 Materials and methods. A clinical case de Quervain's subacute in patient diffuse hypermetabolic 18-fluorodeoxyglucose uptake by the gland presented.
 Results. 61-year-old no history disorders 3 weeks after CO...

Thyroid gland metastatic tumors are rare in clinical practice. Clear cell RCC is one of common metastatic tumors to thyroid. We here reported a case of incidentally found clear cell renal carcinoma metastasis to the thyroid gland 3 years after nephrectomy, in the thyroidectomy procedure performed for the patient due to the thyroid enlargement caused by multinodular goiter. A 65-year-old Iranian...

OBJECTIVE Thyroid findings or incidentalomas in (18)F-FDG PET/CT studies are relatively frequent, being its clinical significance subject of controversy. The aim of this study was to show our experience in the detection of thyroid incidentalomas by PET/CT studies as well as its follow up. MATERIAL AND METHODS A retrospective and descriptive review was conducted on patients who had thyroid inc...

Introduction: Dental panoramic radiography (DPR) is one of the most frequent diagnostic X-ray procedures, the application of which is currently on a growing trend. During DPR, several radiosensitive tissues, such as the lens of the eyes, parotid gland, and thyroid gland, contribute to the radiation field, and it is necessary to monitor their received dose. The aim of t...

Selective iodide uptake and prolonged iodine retention in the thyroid is the basis for targeted radioiodine therapy for thyroid cancer patients; however, salivary gland dysfunction is the most frequent nonthyroidal complications. In this study, we have used noninvasive single photon emission computed tomography functional imaging to quantify the temporal dynamics of thyroidal and salivary radio...

CONTEXT Immune checkpoint blockade is associated with endocrine-related adverse events. Thyroid dysfunction during pembrolizumab therapy, an anti-programmed cell death 1 (PD-1) receptor monoclonal antibody, remains to be fully characterized. OBJECTIVE To assess the incidence and characteristics of pembrolizumab-associated thyroid dysfunction. DESIGN AND SETTING Thyroid function was monitore...

Total activities due to the ingestion of I were evaluated in different compartments of the human body of patients. It has been shown that the 131 I activity in urine of patients increases when the 131 I uptake decreases which could represent a source of radiation for their relatives when they leave hospitals. A new dosimetric model based on the specific betadose concept was developed for evalua...

BACKGROUND The effect of feeding a limited iodine diet on radioactive iodine uptake in the thyroid glands of hyperthyroid cats is unknown. OBJECTIVES To determine how feeding limited dietary iodine affects radioactive iodine uptake by the thyroid glands of hyperthyroid cats. ANIMALS Eight geriatric cats with spontaneous hyperthyroidism. METHODS Prospective study of eight client owned hype...

 Seasonal changes of the thyroid gland structure and hormones secretion was examined in yellowfin seabream (Acanthopagrus latus) in the northwest of Persian Gulf (Musa creek). Thyroid gland composed of follicles scattered around the ventral aorta, near the gills. Follicular cells varied according to secretion of the gland during warm and cold seasons. Thyroid hormones (Triidothyronine [T3] and ...

In addition to a variety of effects on the intermediary metabolism of the thyroid gland, and perhaps as a consequence thereof, the thyrotropic hormone of the anterior pituitary (TSH) induces thyroidal hypertrophy, hyperplasia, and hypervascularity and stimulates most, if not all, phases of iodine metabolism leading to the synthesis and secretion of thyroid hormone (1, 2). Decreases in thyroid c...
