objectives we aimed to assess the prevalence of autoimmune thyroid disorders among patients with vitiligo who referred to sina hospital of hamadan in west of iran in 2008. patients and methods this case-control study comprised 45 patients with vitiligo and 45 healthy individuals (control group). data on age, gender, family history of vitiligo, distribution pattern and duration of the disease we...

 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 [...

Thyroid ectopia is a dysgenesis of thyroid gland and Lingual position represents the most frequent ectopic location accounting up to 90% of ectopic cases. Hypothyroidism is commonly present because of absence of a normal thyroid gland in most instances. Primary hypothyroidism in juvenile population generally leads to retardation of linear growth and delay or even arrested puberty. We present a ...

Radioactive iodine (1311) has a part to play in the therapy of two thyroid disorders, carcinoma and thyrotoxicosis, by virtue of the selective concentration of it which occurs in functioning thyroid cells. The latter represent the only significant site of concentration of the iodide ion in the body, this occurring because of the necessity to incorporate iodine into the molecule of the thyroid h...

The combination of autoimmune Graves’ disease with a solitary hot thyroid nodule suppressing the remainder of the thyroid gland is rare. We report a case of Graves’ disease associated with a single hyperfunctioning nodule with suppression of the remaining gland. A 45 year old male patient with past medical history of autoimmune Graves’ disease with severe ophthalmopathy was referred to endocrin...

Ectopic thyroid is an uncommon embryological aberration of the thyroid descent. Subhyoid median ectopic thyroid gland is a result of incomplete descent of the thyroid anlage and is characterized by a cosmetically unacceptable ovoid mass of thyroid tissue in the midline overlying the thyroid cartilage and thyrohyoid membrane. A normally placed thyroid gland is not detectable and in most cases al...

Background: Although thyroid nodules are less common in children and adolescents, the malignancy rate for nodules is higher among children and adolescents than adults. A nodule that is discovered in a patient presenting with hyperthyroidism is usually a benign nodule or benign toxic adenoma and, thus, nodules are biopsied only infrequently. Objective: To report a case of papillary thyroid carci...

the use of panoramic radiography, due to its numerous advantages, is increasing. radiographic films used in this technique are of double emulsion (de) type which are used with intensifying screens. single emulsion (se) films can also be used. the purpose of this study was to determine the exposure parameters to achieve an appropriate optical density in these two types of films, and to estimate ...

BACKGROUND Non-functioning parathyroid carcinoma is a rare disease that is difficult to distinguish from other diseases based on the lack of hyperparathyroidism. This is a report of non-functioning parathyroid carcinoma diagnosed by reverse transcription polymerase chain reaction (RT-PCR) targeting parathyroid hormone (PTH) messenger RNA. CASE PRESENTATION The patient is a 67-year-old male wh...

The generic term thyrotoxicosis defines the clinical syndrome of hypermetabolism associated with excess amounts of circulating free thyroxine (T4) and (or) triiodothyronine (T3) concentrations, irrespective of the source of the excess hormones. The term hyperthyroidism is reserved for those patients with thyrotoxicosis caused by increased synthesis and secretion of thyroid hormones from the gla...
