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.
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...
Graves Disease II: Pathophysiology01:24

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 I: Introduction01:25

Hyperthyroidism I: Introduction

Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
Hypothyroidism II: Pathophysiology01:23

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...
Hyperthyroidism II: Pathophysiology01:27

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...

Summary
This summary is machine-generated.

Hypocalcemia after hemithyroidectomy is common but typically transient. Serum calcium levels normalize within a week, reducing the need for interventions in most patients.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Neurosurgery

Background:

  • Hypocalcemia is a known complication of total thyroidectomy.
  • Hypocalcemia following subtotal thyroidectomy is less understood.
  • Parathyroid gland function is crucial for calcium homeostasis.

Purpose of the Study:

  • To prospectively evaluate the incidence and pattern of hypocalcemia after hemithyroidectomy.
  • To determine the duration of postoperative hypocalcemia.
  • To identify factors influencing postoperative calcium levels.

Main Methods:

  • Prospective observational study of 107 patients undergoing hemithyroidectomy.
  • Serum calcium and albumin measured preoperatively and at 1 and 7 days postoperatively.
  • Analysis of calcium levels in relation to pathology, sex, and race.

Main Results:

  • A significant decrease in mean serum calcium was observed on postoperative day 1 (8.4 mg/dL) compared to preoperative levels (9.1 mg/dL).
  • Serum calcium levels significantly increased from day 1 to day 7 (9.0 mg/dL), returning to preoperative levels.
  • No significant difference was found between preoperative and 7-day postoperative calcium concentrations.
  • No significant relationship between calcium levels and disease pathology, sex, or race was identified.

Conclusions:

  • Postoperative hypocalcemia after hemithyroidectomy is typically transient, with serum calcium normalizing by one week.
  • Routine calcium replacement or prolonged hospitalization is generally not necessary.
  • Exceptions include patients with preoperative hypocalcemia, prior thyroid surgery, or parathyroid gland devascularization/resection.
