Summary
Newborn screening (NBS) for congenital hypothyroidism (CH) is crucial for preventing intellectual disabilities. Early diagnosis and treatment via NBS ensure normal neurocognitive development, though global access remains a challenge.
Area of Science:
- Pediatrics
- Endocrinology
- Neonatal Health
Background:
- Untreated congenital hypothyroidism (CH) can cause irreversible intellectual disabilities.
- Newborn screening (NBS) for CH is vital for early detection and intervention.
- Global NBS coverage for CH is insufficient, leaving many neonates at risk.
Purpose of the Study:
- To emphasize the importance of universal NBS for CH.
- To highlight the neurocognitive benefits of early CH diagnosis and treatment.
- To discuss challenges and recommendations for CH management.
Main Methods:
- Review of current literature on CH screening and management.
- Analysis of treatment protocols and outcomes.
- Discussion of special populations and diagnostic controversies.
Main Results:
- Prompt NBS and treatment lead to normal adult neurocognitive outcomes.
- Levothyroxine is the standard initial treatment for CH.
- NBS alone is insufficient; timely diagnosis confirmation, accurate testing, and follow-up are essential.
Conclusions:
- Universal NBS for CH is critical for preventing developmental delays.
- Comprehensive management, including clinical vigilance, is necessary for optimal CH care.
- Further efforts are needed to expand global NBS programs for CH.

01:20Synthesis and Regulation of Thyroid Hormones
4.8K
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 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...

01:23The Thyroid Gland
4.1K
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...

01:15Diabetes: Management and Pharmacotherapy
324
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

01:24Cystic Fibrosis: Management
208
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
