Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

5.2K
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

3.3K
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

3.2K
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...

The Parathyroid Glands00:59

The Parathyroid Glands

3.3K
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...

Roles of Electrolytes: Calcium and Phosphate01:27

Roles of Electrolytes: Calcium and Phosphate

767
Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.
The calcium concentration in blood plasma is primarily...

Urinary Tract Calculi I: Introduction01:28

Urinary Tract Calculi I: Introduction

191
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

Summary

Sarcoidosis is an uncommon cause of hypercalcemia, a condition often stemming from primary hyperparathyroidism or cancer. Prompt diagnosis and treatment, including corticosteroids for sarcoidosis-related hypercalcemia, are essential.

Area of Science:

  • Internal Medicine
  • Endocrinology

Background:

  • Hypercalcemia is a common clinical problem.
  • Primary hyperparathyroidism and malignancy are the most frequent causes of hypercalcemia.
  • Sarcoidosis is a rare granulomatous disease that can also lead to hypercalcemia.

Purpose of the Study:

  • To highlight sarcoidosis as a rare cause of hypercalcemia.
  • To emphasize the importance of a systematic diagnostic approach for hypercalcemia.
  • To outline therapeutic strategies for hypercalcemia, particularly when associated with sarcoidosis.

Main Methods:

  • Literature review of hypercalcemia causes.
  • Case study analysis (implied).
  • Review of diagnostic and therapeutic guidelines for hypercalcemia.

Main Results:

  • Sarcoidosis is identified as an infrequent etiology of hypercalcemia.
  • Differential diagnosis for hypercalcemia is broad, including other granulomatous diseases.
  • Standard treatments for hypercalcemia involve fluid replacement and bisphosphonates.

Conclusions:

  • A systematic diagnostic workup is crucial for hypercalcemia due to its diverse causes.
  • Systemic corticosteroids are the recommended treatment for hypercalcemia caused by sarcoidosis.
