Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

4.2K
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

2.5K
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...

Desensitization and Tachyphylaxis

1.5K
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.

Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

3.1K
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.

The Thyroid Gland01:23

The Thyroid Gland

3.5K
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...

Psychosis: Goals of Pharmacotherapy

103
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Area of Science:

  • Endocrinology
  • Thyroid Disorders
  • Clinical Medicine

Background:

  • Thyrotoxicosis management requires understanding factors influencing recovery time.
  • Optimizing treatment plans depends on identifying predictors of delayed thyroid function normalization.

Purpose of the Study:

  • To identify predictive factors for delayed thyroid function recovery in thyrotoxicosis patients.
  • To analyze the impact of patient characteristics and treatment on TSH normalization time.

Main Methods:

  • Retrospective review of 443 adult thyrotoxicosis patients' medical records (Jan 2014 - Dec 2021).
  • Inclusion criteria: age > 18, TSH <0.1 μIU/mL, treated with CBZ or PTU, with subsequent TSH > 0.4 μIU/mL.
  • Follow-up duration of at least 18 months for thyroid function recovery.

Main Results:

  • Average time to normalized TSH levels was 6.9 months.
  • Predictors of delayed TSH normalization: higher BMI (OR=1.06), elevated free T4 (OR=1.97), and propylthiouracil (PTU) treatment (OR=2.66).
  • Sex, age, season of diagnosis, and comorbidities did not significantly affect TSH normalization rates.

Conclusions:

  • Individual patient factors like BMI and initial free T4 levels are crucial for thyrotoxicosis management.
  • Carbimazole (CBZ) may be preferred over PTU for faster TSH normalization.
  • Findings support personalized treatment approaches for improved thyrotoxicosis recovery.
