Euthyroid sick syndrome ( ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [ 1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional. This condition may result from allostatic responses of hypothalamus-pituitary-thyroid feedback control, dyshomeostatic disorders ...
Thyroid disease is a medical condition that affects the function of the thyroid gland. The thyroid gland is located at the front of the neck and produces thyroid hormones [ 1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ. These hormones normally act in the body to regulate energy use ...
Thyroid nodules are nodules (raised areas of tissue or fluid) which commonly arise within an otherwise normal thyroid gland. [ 1] They may be hyperplastic or tumorous, but only a small percentage of thyroid tumors are malignant. Small, asymptomatic nodules are common, and often go unnoticed. [ 2] Nodules that grow larger or produce symptoms may ...
Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis and Hashimoto's disease, is an autoimmune disease in which the thyroid gland is gradually destroyed. [ 1][ 6] A slightly broader term is autoimmune thyroiditis, identical other than that it is also used to describe a similar condition without a goiter. [ 7][ 8] Early on ...
Thyrotoxic periodic paralysis ( TPP) is a rare condition featuring attacks of muscle weakness in the presence of hyperthyroidism (overactivity of the thyroid gland). Hypokalemia (a decreased potassium level in the blood) is usually present during attacks. The condition may be life-threatening if weakness of the breathing muscles leads to ...
[6] As a life-threatening medical emergency, thyroid storm has a mortality rate of up to 25% despite treatment. [1] [7] Without treatment, the condition is typically fatal, with a mortality rate of 80-100%. [8] Historically, the condition was considered untreatable, with hospital mortality rates approaching 100%. [9] [10]
The ICD coding for rare diseases is the International Classification of Diseases code used for the purpose of documenting rare diseases. It is important for health insurance reimbursement, administration, epidemiology, and research. Of the approximately 7,000 rare diseases, only about 500 have a specific code.
Thyroid hormone binding ratio (THBR) is a thyroid function test that measures the "uptake" of T3 or T4 tracer by thyroid-binding globulin (TBG) in a given serum sample. This provides an indirect and reciprocal estimate of the available binding sites on TBG within the sample. The results are then reported as a ratio to normal serum.
