Ectopic intrathyroidal thymic tissue can form a mass lesion within the thyroid gland and has rarely been reported in children. We report a case of intrathyroidal thymus accompanied by an intrathyroidal parathyroid gland in a 29-year-old woman who visited our hospital due to right neck mass diagnosed as metastatic papillary carcinoma by aspiration cytology in an outside hospital. She had a histo...

An experiment was conducted to investigate the effect of thyroid gland activity modulation (Hyper or hypothyroidism) on energy utilization in broiler chickens. Two hundred and forty one-day-old Cobb broiler chicks were distributed into three dietary metabolizable energy (ME) treatment groups (80 chicks each). The control group (E0) was fed basal diet (3150 kcal/kg diet), the second group (E1) w...

The thyroid gland is the only source of thyroid hormone production. Thyroid hormone is essential for growth and development, and is of special importance for the development of the central nervous system. It was for that reason that neonatal screening on congenital hypothyroidism was introduced and is now performed in many countries. Defects in thyroid hormone production are caused by several d...

Since 1963 lithium treatment has been the best proven long-term pharmacotherapy for bipolar disorder (BD), both in the prevention of depressive and manic episodes, along with the reduction of the suicide risk. Thyroid gland and the hypothalamic-pituitary-thyroid (HPT) axis play a role in the pathophysiology, clinical course and treatment of BD. The influence of lithium on the thyroid gland is o...

Ectopic thyroid tissue refers to presence of thyroid tissue at locations away from the normal site in the pretracheal region in the lower neck. Few of such cases are associated with a functioning thyroid gland in its normal anatomical location. However in many cases, the ectopic thyroid gland is the only functioning thyroid. Radionuclide scan is mandatory when dealing with an ectopic thyroid le...

Early investigations, both experimental and clinical, created the impression that the thyroid gland is relatively resistant to injury by ionizing radiation (86, 87). The results of the many studies carried out during the past decade, however, not only have reversed this view, but have, in fact, emphasized that destructive lesions of the gland can be readily produced in man and several species o...

INTRODUCTION Hyperthyroidism is a syndrome caused by the excessive production and secretion of the thyroid hormones T3 and T4 by an autonomous thyroid gland. Feline hyperthyroidism was first reported in 1979 and since then it has become a common disease in cats. Histopathology of affected thyroids usually reveals thyroid hyperplasia or benign thyroid adenoma, however in a small percentage of ca...

ABSTARCT The thyroid gland is highly vascular organ and it lies in the interior part of the neck just below the thyroid cartilage.In medical organization,there are many ways to detect the affected interior part of the thyroid gland like CT/MRI and ultrasound imaging.But CT/MRI are expensive techniques as compare to US images.But US images are blurred and consist of noise.In the existing method,...

1 University of Wisconsin Integrative Medicine www.fammed.wisc.edu/integrative As a major regulator of cellular metabolism, the thyroid gland influences an astonishing number of physiologic processes with include development and growth, thermogenesis, lipid and carbohydrate metabolism, cardiac myocyte activity, reproduction and cognitive functioning. This important gland is characteristic of ve...

OBJECTIVE To examine the presentation, diagnosis, and appropriate management of renal clear cell carcinoma metastasis to the thyroid gland. METHODS We describe a clinical case of solitary thyroid metastasis from renal clear cell carcinoma and present a comprehensive review of the related English-language literature. Common patterns of presentation and generalized overall management recommenda...
