The Thyroid Gland01:23

The Thyroid Gland

5.5K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Synthesis and Regulation of Thyroid Hormones

6.2K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Functions of Thyroid Hormones

4.1K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Area of Science:

  • Endocrinology
  • Otolaryngology
  • Epidemiology

Background:

  • Investigates the relationship between thyroid disorders and benign paroxysmal positional vertigo (BPPV).
  • Accounts for levothyroxine medication use in the analysis.
  • Examines common thyroid conditions including goiter, hypothyroidism, thyroiditis, and hyperthyroidism.

Purpose of the Study:

  • To determine if there is an association between specific thyroid disorders and the occurrence of BPPV.
  • To quantify the risk of BPPV in patients with a history of thyroid disease.

Main Methods:

  • Utilized data from the Korean National Health Insurance Service-Health Screening Cohort (2002-2015).
  • Matched 19,071 BPPV patients with 76,284 controls based on age, sex, income, and region.
  • Employed conditional logistic regression to calculate odds ratios for BPPV in relation to thyroid diseases.

Main Results:

  • Higher prevalence of goiter, hypothyroidism, thyroiditis, and hyperthyroidism observed in the BPPV group compared to controls (p < 0.001).
  • Goiter, hypothyroidism, and hyperthyroidism were significantly associated with an increased odds of BPPV.
  • Adjusted odds ratios indicated a notable link between these thyroid conditions and BPPV.

Conclusions:

  • Benign paroxysmal positional vertigo (BPPV) is associated with several thyroid disorders.
  • Conditions such as goiter, hypothyroidism, thyroiditis, and hyperthyroidism are linked to BPPV.
  • Findings suggest a potential connection between thyroid health and vestibular disorders like BPPV.
