Assessment of Thyroid Function
Ophthalmology, 1981The thyroid hormones Thyroxine (T4) and Triiodothyronine (T3) can be measured directly in serum by radioimmunoassay. Most serum T4 and T3 circulates bound to specific serum-binding proteins but the small unbound fraction, free T4, correlates best with hormonal activity.

Thyroid, 1992
Cordocentesis has permitted the study of fetal thyroid function in utero. In normal fetuses, fetal TSH, TBG, and thyroid hormone concentrations increase progressively throughout intrauterine life. Fetal TSH concentrations are always high compared to nonpregnant adult values. TBG concentrations reach adult levels at term.

Emergencies in Thyroid Function
Journal of Emergency Nursing, 2009The thyroid gland can be an overlooked source of a medical emergency. This butterfly-shaped gland is located just inferior to the larynx on the anterior neck and is responsible for the metabolic rate of many processes in the human body. A hyperthyroid state elevates the rate of metabolism, and a hypothyroid state is cause for a decreased metabolic rate.

A reciprocal interaction between the hypothalamo-pituitary-thyroid axis and the adipose tissue is required for the proper homeostasis of energy balance. In this chapter, the mechanisms by which the two systems regulate each other and the effects of thyroid dysfunctions on body weight will be discussed.

Archives of Pediatrics & Adolescent Medicine, 1984
Sir .—In a report by Lyen and associates 1 in AJDC , a male neonate was described in whom the serum thyroxine (T 4 ) and thyroid-stimulating concentrations underwent an interesting sequence of changes during the first two months of life; they ascribed these changes to prolonged exposure to povidone-iodine solution.

Thyroid hormones are essential for normal growth, sexual development and reproductive function. During puberty, changes in thyroid functions and an increase in thyroid volume occur as an adaptation to body and sexual development. Hypothyroidism diagnosed late in prepubertal years, usually due to Hashimoto's thyroiditis, can cause a delay of puberty or ...

Molecular and Cellular Endocrinology, 2010
A moderate elevation of thyrotropin (TSH) concentrations, which is associated with triiodothyronine (T3) values in or slightly above the upper normal range, is frequently found in obese humans. These alterations seem rather a consequence than a cause of obesity since weight loss leads to a normalization of elevated thyroid hormone levels.

Thyroid Function in the Elderly
Clinics in Geriatric Medicine, 1988Many differences in thyroid function exist between elderly and younger populations. Although serum T4 levels probably do not change with age, serum T3 levels appear to decline. Hyperthyroidism in the geriatric population may be atypical and is characterized by anorexia and constipation. The pulse rate is often slower than in younger patients. Apathetic
