Insights

Congenital hypothyroidism, a common childhood endocrine disorder, requires prompt screening and treatment. This review examines publications on managing and reevaluating thyroid function in newborns to distinguish permanent from transient cases.

Area of Science:

  • Pediatrics
  • Endocrinology
  • Neonatal screening

Background:

  • Congenital hypothyroidism is a prevalent endocrine disorder in children.
  • Neonatal screening for congenital hypothyroidism in Türkiye began in 2007, using a Thyroid Stimulating Hormone (TSH) cutoff of 5.5 mU/L.
  • Initial treatment is mandated within the first 14 days of life.

Purpose of the Study:

  • To review existing literature on congenital hypothyroidism.
  • To discuss the reevaluation process for determining permanent versus transient congenital hypothyroidism.
  • To synthesize current knowledge and proposals regarding diagnosis and management.

Main Methods:

  • Literature review of publications on congenital hypothyroidism.
  • Analysis of screening protocols and treatment guidelines.
  • Synthesis of findings on thyroid function reevaluation.

Main Results:

  • Established screening protocols and early treatment initiation are crucial.
  • Reevaluation is essential for accurate diagnosis of permanent or transient congenital hypothyroidism.
  • Numerous studies provide insights into management strategies.

Conclusions:

  • Effective management of congenital hypothyroidism relies on timely screening and appropriate reevaluation.
  • Distinguishing between permanent and transient forms is critical for long-term patient care.
  • Continued research and adherence to guidelines are necessary for optimal outcomes.

Synthesis and Regulation of Thyroid Hormones

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

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

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...
