Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

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.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
Hormones and Bone Tissue01:17

Hormones and Bone Tissue

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...
Synthesis and Functions of Calcitonin00:51

Synthesis and Functions of Calcitonin

Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...
Study Designs in Epidemiology01:20

Study Designs in Epidemiology

Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.
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...

Summary

Routine calcium level monitoring after thyroid lobectomy is unnecessary, as no hypocalcaemia occurred. However, predicting hypocalcaemia after total or completion thyroidectomy remains challenging.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Neurosurgery

Background:

  • Postoperative hypocalcaemia is a common concern following thyroidectomy.
  • Current practice often involves routine calcium level monitoring to detect this complication.

Purpose of the Study:

  • To prospectively determine the incidence of symptomatic and biochemical hypocalcaemia after thyroidectomy.
  • To identify risk factors associated with hypocalcaemia, including surgical type, histology, and specimen characteristics.
  • To evaluate the necessity of routine postoperative calcium level measurements.

Main Methods:

  • Prospective clinical study involving 86 consecutive patients undergoing thyroid surgery at a university teaching hospital.
  • Data collected included type of surgery, indications, perioperative calcium levels, hypocalcaemia symptoms, and histological findings.
  • Logistic regression analysis was used to identify independent risk factors.

Main Results:

  • No hypocalcaemia was observed in patients undergoing thyroid lobectomy and isthmusectomy (n=54).
  • Hypocalcaemia occurred in 26% of total thyroidectomies (n=19) and 23% of completion thyroidectomies (n=13).
  • Surgical operation type was the sole independent risk factor for developing hypocalcaemia (P=0.021).

Conclusions:

  • Thyroid lobectomy and isthmusectomy do not necessitate routine postoperative calcium level monitoring due to zero incidence of hypocalcaemia.
  • Routine calcium level analysis is unwarranted for the majority of thyroidectomy patients (63% underwent lobectomy).
  • Predicting postoperative hypocalcaemia remains difficult, but surgical approach is a key determinant.
