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...

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...

Genomic Imprinting and Inheritance

34.9K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

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...

Area of Science:

  • Endocrinology
  • Genetics
  • Biochemistry

Background:

  • Hypoparathyroidism is a condition of insufficient parathyroid hormone (PTH) secretion, leading to hypocalcemia.
  • Diagnosis relies on biochemical markers, specifically low calcium and inappropriately low PTH levels.
  • Nonsurgical forms of hypoparathyroidism have diverse genetic origins and clinical presentations.

Purpose of the Study:

  • To summarize diagnostic criteria for hypoparathyroidism.
  • To describe the clinical presentation and genetic causes of nonsurgical hypoparathyroidism.
  • To propose a research agenda for improved diagnosis and prognosis.

Main Methods:

  • Comprehensive literature search (2000-2021) with inclusion of landmark articles prior to 2000.
  • Systematic review on the utility of early post-thyroidectomy calcium and PTH measurements.
  • Analysis of genetic disorders associated with hypoparathyroidism.

Main Results:

  • Hypoparathyroidism diagnosis is confirmed by low calcium and inappropriately low serum PTH.
  • Early post-thyroidectomy PTH and calcium levels can predict long-term hypoparathyroidism.
  • Genetic disorders, often presenting with autoimmune diseases or specific comorbidities, are key causes of nonsurgical hypoparathyroidism.

Conclusions:

  • Accurate diagnosis of hypoparathyroidism requires careful biochemical assessment.
  • Genetic testing and family history are crucial for identifying nonsurgical forms.
  • Further research is needed to enhance diagnostic accuracy and patient outcomes.
