Autoimmune Disorders01:29

Autoimmune Disorders

2.0K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Synthesis and Regulation of Thyroid Hormones

8.4K
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...

The Thyroid Gland01:23

The Thyroid Gland

8.1K
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...

Functions of Thyroid Hormones

6.0K
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...

Adrenal Gland Disorders

3.6K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Summary

Non-autoimmune hyperthyroidism, including autonomic adenomas and TSH receptor mutations (familial or hereditary, FNAH; persistent sporadic congenital non-autoimmune hyperthyroidism, PSNAH), requires accurate diagnosis for effective genetic counseling and treatment.

Area of Science:

  • Endocrinology
  • Genetics
  • Molecular Biology

Background:

  • Hyperthyroidism stems from elevated thyroid hormones, with Graves' disease being autoimmune.
  • Non-autoimmune causes include autonomic adenomas and rare TSH receptor mutations.

Purpose of the Study:

  • To review the epidemiology, etiology, molecular, and clinical aspects of non-autoimmune hyperthyroidism.
  • To guide accurate diagnosis for genetic counseling and presymptomatic family diagnosis.
  • To optimize treatment strategies for persistent or relapsing hyperthyroidism.

Main Methods:

  • Review of literature on autonomic adenomas, familial or hereditary (FNAH), and persistent sporadic congenital non-autoimmune hyperthyroidism (PSNAH).
  • Analysis of epidemiological, etiological, molecular, and clinical characteristics.
  • Focus on diagnostic approaches and treatment implications.

Main Results:

  • Autonomic adenomas are a primary cause of non-autoimmune hyperthyroidism.
  • Activating TSH receptor mutations lead to FNAH (autosomal dominant) or PSNAH (sporadic).
  • These three conditions represent inheritable and sporadic non-autoimmune hyperthyroidism.

Conclusions:

  • Accurate diagnosis of non-autoimmune hyperthyroidism is crucial for genetic counseling and presymptomatic testing.
  • Understanding the specific etiology guides optimal, individualized treatment plans.
  • Timely diagnosis and management prevent long-term hyperthyroid complications.
