Skeleton and Calcium Homeostasis

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.

Synthesis and Functions of Calcitonin

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...

Hormones and Bone Tissue

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...

Graves Disease II: Pathophysiology

Graves Disease II: Pathophysiology

Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...

Hyperthyroidism II: Pathophysiology

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

Hypothyroidism II: Pathophysiology

Hypothyroidism II: Pathophysiology

Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...

Summary

Post-thyroidectomy hypocalcemia affects over 20% of patients, often resolving within a week. Key causes include inadvertent parathyroid gland removal, ischemia, and injury during surgery.

Area of Science:

Endocrinology
Surgical Oncology

Context:

Thyroidectomy is a common surgical procedure.
Hypocalcemia is a recognized complication following thyroidectomy.
The precise causes of post-thyroidectomy hypocalcemia require further elucidation.

Purpose:

To investigate the incidence and potential causes of hypocalcemia after thyroidectomy.
To analyze preoperative and postoperative serum calcium, ionized calcium, parathyroid hormone (PTH), and phosphate levels in patients undergoing thyroidectomy.

Summary:

A study of 804 patients (594 total thyroidectomy, 209 emithyroidectomy) revealed a 21.2% incidence of hypocalcemia (serum calcium < 7.5 mg/dL).
In most cases (90.6%), serum calcium normalized within seven days post-surgery.
Two patients developed permanent hypoparathyroidism at 180 days, highlighting potential long-term risks.

Impact:

Identifies inadvertent parathyroid gland excision, ischemia, and injury as primary contributors to hypocalcemia post-thyroidectomy.
Provides crucial data for surgical technique refinement and patient management strategies to mitigate hypocalcemia risk.
Contributes to understanding the pathophysiology and clinical course of post-thyroidectomy hypocalcemia.
