Unique among malignancies, age is a key prognostic indicator for well-differentiated thyroid cancer. Patients aged <45 years can have the same degree of disease involvement and a distinctly different prognosis than those aged >45. Although the reason for the association between age and outcome is not entirely clear, it does ...

Painless thyroiditis is characterized by transient thyrotoxicosis with complete recovery. Some patients, however, have repeated episodes of thyrotoxicosis, for which the mechanism of recurrence is not clear. We therefore studied the clinical characteristics in 8 patients with 4 or more episodes of thyrotoxicosis and 40 control patients. The age at ...

The pituitary gland undergoes important changes in cellular plasticity throughout life, consequently leading to hormonal output changes. The intermediate filament nestin plays a crucial role in cells that retain plasticity during development, aging and tumorigenesis. Here, we describe robust nestin immunoreactivity in glial-like cells of the intermediate lobe and in ...

: Thyroid function is closely related to leptin's secretion by the adipose tissue. In states of leptin-deficiency, the circadian rhythm of TSH is altered, leading to central hypothyroidism in animal models. In humans, central hypothyroidism has also been described in rare cases of congenital leptin deficiency. However, the thyroid phenotype ...

The endocrine system is as affected by aging as are other systems. The effect of aging on the hypothalamus-pituitary-thyroid function is still controversial. Human aging was reported as associated with a decrease in thyrotropin (TSH) secretion, but increased TSH levels in relatively healthy elders are also reported. The main point ...

BACKGROUND AND AIMS: The optimal dose of thyroxine (T4) in congenital hypothyroidism (CH) during infancy is controversial. Higher doses lead to improvement in cognitive scores, but have been linked to later behavioural difficulties. We have examined the effects of initial T4 dosage on somatic growth--a putative surrogate marker of overtreatment. ...
