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...

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...

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...

Major Hormones and Their Functions01:27

Major Hormones and Their Functions

862
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...

Hypertension III: Clinical Manifestations and Diagnostic Studies

67
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

59
Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

    Summary
    This summary is machine-generated.

    Subclinical hypothyroidism, often a lab finding, may resolve spontaneously. Treatment in the elderly is cautioned due to risks outweighing benefits, necessitating careful consideration, especially in pregnant women.

    Area of Science:

    • Endocrinology
    • Internal Medicine

    Background:

    • Subclinical hypothyroidism is defined by elevated thyroid-stimulating hormone (TSH) with normal thyroid hormones.
    • Spontaneous normalization occurs in 50% of cases within months.
    • Diagnosis is complicated by age-related TSH increases and autoimmune thyroiditis.

    Purpose of the Study:

    • To evaluate the necessity and risks of treating subclinical hypothyroidism.
    • To highlight the specific challenges in diagnosing and managing subclinical hypothyroidism in the elderly and pregnant women.

    Main Methods:

    • Review of existing studies on subclinical hypothyroidism treatment efficacy and risks.
    • Analysis of diagnostic criteria and management guidelines.

    Main Results:

    • Substitution therapy for subclinical hypothyroidism, particularly in the elderly, has not shown clear benefits.
    • Overtreatment carries risks, including subclinical hyperthyroidism, atrial fibrillation, and osteoporosis.
    • Pregnant women require careful management due to dual patient (mother and child) considerations.

    Conclusions:

    • Substitution therapy for subclinical hypothyroidism should be approached with caution.
    • The diagnosis and treatment require special sensitivity in elderly and pregnant populations.
    • Risk-benefit assessment is crucial before initiating treatment, especially in older adults.
