Thyroid diseases in children and adolescents include acquired or congenital conditions, including genetic disorders either isolated part of a syndrome. Briefly, we will review the physiology pathophysiology thyroid gland its disorders. The aim this chapter is to describe abnormalities gland.

introduction:  the use of radioactive iodine (131i) has become an important adjunct to the treatment of thyroid cancer and hyperthyroidism. salivary gland has the ability to concentrate radioactive iodine under normal circumstances. salivary gland dysfunction and dry mouth are the common side effectsof high-dose radioiodine therapy. the purposeof this study was to determine the absorbed dose of...

 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 [...

if "'5I therapy is used in these cases the thyroid gland will be permanently damaged and hypothyroidism will inevitably result. The problem then lies in identifying this group of patients beforehand rather than trying to reduce the dose of ...I. Hence, although a correlation between high thyroid antibody titres and post-radiation hypothyroidism has yet to be shown, it would seem wise not to tre...

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 ...

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 ...

Cancer of the thyroid is a rare disease. Only 350 deaths from thyroid malignancy were recorded in England and Wales in 1957 out of a total of 95,6oo deaths due to malignant disease, and 1,050 in the United States of America out of 253,000. However, considerable information about thyroid cancer is accumulated in the many hundreds of cases reported, chiefly in the United States of America, during...

background: intraoral radiographs are believed to deliver low doses to patients, thus little work has been done in this regards. considering the increment in the number of patients reporting for the examination and the probability of delayed somatic effects for accumulated low doses of x-irradiation, it is expedient to determine the doses to three critical organs eye, thyroid and parotid that a...
