Bone Disorders01:29

Bone Disorders

3.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

4.7K
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 Calcitonin00:51

Synthesis and Functions of Calcitonin

2.1K
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 Tissue01:17

Hormones and Bone Tissue

2.8K
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...

The Parathyroid Glands00:59

The Parathyroid Glands

2.3K
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...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.1K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Summary

Vitamin D-dependent rickets are genetic disorders causing calcium and phosphate imbalances in children. Early diagnosis and understanding these conditions are key for developing targeted, mutation-specific therapies.

Area of Science:

  • Pediatrics
  • Endocrinology
  • Genetics

Background:

  • Rickets involves pediatric calcium and phosphate balance disturbances.
  • Vitamin D-dependent rickets are hereditary disorders causing early-onset rickets.
  • These conditions stem from inadequate response to or maintenance of active vitamin D forms.

Purpose of the Study:

  • To review the classification and clinical manifestations of vitamin D-dependent rickets.
  • To highlight the genetic basis of various types of vitamin D-dependent rickets.
  • To emphasize the need for further research in developing targeted therapies.

Main Methods:

  • Literature review of vitamin D-dependent rickets.
  • Classification based on age of onset and pathophysiology.
  • Identification of genetic forms (1A, 1B, 2A, 2B, and 3).

Main Results:

  • Vitamin D-dependent rickets present with clinical signs like growth failure, limb bowing, and joint enlargement.
  • Five genetic forms of vitamin D-dependent rickets are identified.
  • Pathophysiology and age of onset vary across different types.

Conclusions:

  • Further research is essential for advancing treatment strategies.
  • Development of targeted therapies for specific mutations is crucial.
  • Understanding the genetic basis aids in managing pediatric rickets.
