Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

5.3K
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

4.5K
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...

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

3.3K
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...

Major Hormones and Their Functions01:27

Major Hormones and Their Functions

855
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Changes in Skin Color: Clinical Perspectives

2.5K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

4.2K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.
Humoral...

Summary

Polymorphic light eruption (PMLE) patients show significantly elevated thyroid-stimulating hormone (TSH) and low triiodothyronine (T3) and thyroxine (T4) levels. This suggests a potential link between PMLE and thyroid dysfunction, warranting further investigation.

Area of Science:

  • Dermatology
  • Endocrinology
  • Immunology

Background:

  • Polymorphic light eruption (PMLE) is a common skin condition triggered by UV radiation, often with an uncertain autoimmune basis.
  • Thyroid disorders, particularly autoimmune thyroid diseases, are prevalent and can influence systemic health.
  • The potential connection between PMLE and thyroid function remains underexplored.

Purpose of the Study:

  • To investigate and compare biochemical thyroid function tests in individuals diagnosed with PMLE.
  • To explore a potential association between PMLE and thyroid dysfunction.

Main Methods:

  • A case-control study involving 120 participants (PMLE patients and controls).
  • Analysis of thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4) levels.
  • Statistical analysis using SPSS, including chi-square tests, with a p-value <0.05 considered significant.

Main Results:

  • Elevated TSH levels were observed in 93.3% of PMLE cases compared to 3.3% in controls.
  • Low T3 and T4 levels were found in 40% of PMLE cases versus 11.7% in controls.
  • These findings indicate a significant difference in thyroid function between PMLE patients and the control group.

Conclusions:

  • The results suggest a potential link between PMLE and thyroid disorders, possibly due to shared autoimmune mechanisms.
  • Screening for thyroid dysfunction in PMLE patients is recommended due to their increased risk.
  • Further research with larger cohorts is needed to clarify the autoimmune or incidental nature of this association.
