BACKGROUND Although numerous reports have discussed the upper limit of the thyrotropin (TSH) reference interval, none have dealt with the lower limit. Recent recommendations regarding subclinical thyroid dysfunction give different advice about its management, depending on whether the TSH concentration is <0.1 mIU/L or 0.1-0.4 mIU/L. CONTENT We review key studies that have investigated the lin...

OBJECTIVE An anaesthetic approach and surgery are important treatment strategies in patients with thyroid dysfunction due to potential complications. We investigated the prevalence of thyroid disorders, the significance of thyroid function tests (TFTs) with respect to anaesthesia in the preoperative period and the need for routine examinations. METHODS A total of 10,600 patients who were admi...

Subclinical hyperthyroidism and subclinical hypothyroidism are characterized by abnormal thyroid stimulating hormone (TSH) with normal free thyroxine. Subclinical thyroid diseases, to date, have received less attention compared with other thyroid diseases since they are asymptomatic. This study aimed to verify the association between subclinical thyroid diseases and cardiovascular diseases (CVD...

CONTEXT AND OBJECTIVE Subclinical thyroid dysfunction is very common in clinical practice and there is some evidence that it may be associated with cardiovascular disease. The aim here was to evaluate the frequencies of subclinical thyroid disease and risk factors for cardiovascular disease among women at a workplace, and to evaluate the association between subclinical thyroid disease and cardi...

Background: Numerous hormonal changes and metabolic demands occur during pregnancy, resulting in complex maternal thyroid function. Thyroid disorder is the second most common endocrine found pregnancy next to diabetes group. It affects 1–2% of women reproductive age. Overt hypothyroidism complicates 0.3–0.5% pregnancies. The incidence subclinical pregnant about 2–3%. Hyperthyroidism present 0.1...

Thyroid hormone excess due to any cause is state of thyrotoxicosis, whereas hyperthyroidism is a state of thyroid hormone excess due to hyperfunctioning of thyroid gland. The major causes of thyrotoxicosis include Graves’ disease, solitary toxic adenoma, and toxic multinodular goiter. In thyrotoxicosis, free hormone levels are invariably increased. The reverse is not true in that increased free...
