background  it is remain a main concern that pediatric chest radiographies contribute to the significant radiation exposure to the thyroid gland as a more susceptible organ to radiation induced cancer. the aim of this study was to evaluate the entrance surface dose (esd) of pediatric chest radiography compared to the diagnostic reference levels (drl) and evaluation the efficacy of the lead (pb)...

An ectopic location of the thyroid gland usually occurs in the midline, starting anywhere from the tongue to the diaphragm. The occurrence of an ectopic thyroid gland in a non-midline site is extremely rare. We report a 32-year-old Malay woman with an aberrant thyroid gland presenting as a parapharyngeal lesion. She had a normally functioning thyroid gland. An ectopic thyroid should be consider...

objective(s): we investigated a frequency of lower extremity uptake on the radioactive iodine (rai) whole body scan (wbs) after rai treatment in patients with differentiated thyroid cancer, in order to retrospectively examine whether or not the frequency was pathological. methods: this retrospective study included 170 patients with thyroid cancer, undergoing rai treatment. overall, 99r (58%) an...

It is not uncommon to encounter variations in the Thyroid gland during surgeries. Complete detailed anatomical variations in arterial and venous supply including the presence of ectopic glands is useful for diagnosis and prognosis of patients involved with thyroid disorders. With these facts we tried to evaluate the Anatomical and Morphological variations of the thyroid gland. The study was con...

The effects of kojic acid (KA) on thyroidal function were studied by single-dose administration in rats and in cultured rat thyroid cells (FRTL-5 cells). In rats receiving a single dose of 1,000 mg/kg KA orally, the 125I uptake from blood into the thyroid gland was significantly lower than that of the control group from 30 min to 24 hr after administration. The 125I organification activity of t...

The external branch of the superior laryngeal nerve (ELN) is intimately associated with the superior thyroid artery (STA) in relation to the superior pole of the thyroid gland, rendering it vulnerable to injury during the ligation of this vessel during thyroidectomy. Although most texts acknowledge the fact that the nerve is in close relation to the STA, there has not been an anatomical study t...

Goiters (from the Latin guttur, throat) have been known since 2700 b.c., long before the thyroid gland was recognized. The thyroid gland was first documented by the Italians of the Renaissance period. Leonardo da Vinci originally depicted the thyroid in his drawings as two separate glands on either side of the larynx. The term thyroid gland (Greek thyreoeides, shield-shaped) is attributed to Th...
