[1] [3] [4] [5] In the thyrotoxic phase, the follicular cells of the thyroid gland are damaged leading to release of pre-formed thyroid hormone and symptoms of thyrotoxicosis. The damage to the follicles impairs ability to produce and secrete thyroid hormones which then leads to a hypothyroid phase.
Hashimoto's Thyroiditis is a T-lymphocyte mediated attack on the thyroid gland. [15] T helper 1 cells trigger macrophages and cytotoxic lymphocytes to destroy thyroid follicular cells, while T helper 2 cells stimulate the excessive production of B cells and plasma cells which generate antibodies against the thyroid antigens, leading to ...
Ord's thyroiditis is an atrophic form of chronic thyroiditis, an autoimmune disease where the body's own antibodies fight the cells of the thyroid. It is named after the physician, William Miller Ord, who first described it in 1877 and again in 1888. It is more common among women than men.
Thyroid follicular cells form a simple cuboidal epithelium and are arranged in spherical thyroid follicles surrounding a fluid filled space known as the colloid. The interior space formed by the follicular cells is known as the follicular lumen .
The abnormality in the channel is thought to lead to shifts of potassium into cells, under conditions of high thyroxine (thyroid hormone) levels, usually with an additional precipitant. Treatment of the low levels of potassium in the blood, followed by correction of the hyperthyroidism, leads to complete resolution of the attacks.
Micrograph of a Hurthle cell neoplasm. Hurthle cell thyroid cancer is often considered a variant of follicular cell carcinoma. [3] [4] Hurthle cell forms are more likely than follicular carcinomas to be bilateral and multifocal and to metastasize to lymph nodes. Like follicular carcinoma, unilateral hemithyroidectomy is performed for non ...
Various medical conditions such as alopecia areata, lupus, and thyroid disease as well as medical treatments, such as chemotherapy, radiation therapy, and some medications, can also cause hair loss.
Toxic multinodular goiter (TMNG), also known as multinodular toxic goiter (MNTG), is an active multinodular goiter associated with hyperthyroidism.. It is a common cause of hyperthyroidism [2] [3] in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which do not require stimulation from thyroid stimulating hormone (TSH).
