Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

4.7K
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...

Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

4.6K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

The Parathyroid Glands00:59

The Parathyroid Glands

2.2K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

2.7K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

2.8K
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...

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Thyroid Surgery

Background:

  • Total thyroidectomy carries a significant risk of postoperative hypoparathyroidism due to potential damage to parathyroid glands or their vascular supply.
  • Surgeons with expertise in both thyroid and parathyroid procedures may achieve better outcomes in thyroidectomy.
  • High rates of permanent hypoparathyroidism negatively impact patient quality of life and increase long-term morbidity.

Purpose of the Study:

  • To investigate the impact of centralizing total thyroidectomy for Graves' disease to experienced surgeons on postoperative hypoparathyroidism rates.
  • To evaluate the effectiveness of restricting thyroidectomy procedures to surgeons skilled in both thyroid and parathyroid surgery.

Main Methods:

  • A retrospective cohort study was conducted at a single institution.
  • Thyroidectomies for Graves' disease were initially performed by seven surgeons (2012-2016).
  • From 2017, these procedures were restricted to two surgeons with concurrent parathyroid surgery experience.

Main Results:

  • The overall rate of permanent hypoparathyroidism after total thyroidectomy decreased from 28% (2012-2014) to 6% (2020-2021).
  • For Graves' disease patients, permanent hypoparathyroidism rates dropped from 36% (2015-2016) to 2% (2020-2021).
  • In thyroid cancer patients, rates decreased from 30% (2012-2014) to 10% (2020-2021).

Conclusions:

  • Centralizing total thyroidectomy to surgeons with extensive parathyroid surgery experience markedly reduces postoperative hypoparathyroidism.
  • This strategy improves patient outcomes and quality of life by minimizing a serious surgical complication.
  • Recommendations include centralizing complex thyroid operations to high-volume centers with specialized surgical expertise.
