The Parathyroid Glands00:59

The Parathyroid Glands

1.9K
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

2.6K
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...

Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

4.4K
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.

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

2.6K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Synthesis and Functions of Calcitonin00:51

Synthesis and Functions of Calcitonin

1.7K
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...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers01:26

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

147
Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Summary

Primary hyperparathyroidism diagnosis involves assessing renal function, calciuria, and bone density. Routine screening for neurocognitive, quality of life, or cardiovascular issues is not recommended for surgical indications.

Area of Science:

  • Endocrinology
  • Nephrology
  • Bone Metabolism

Background:

  • Primary hyperparathyroidism (PHPT) is often diagnosed incidentally in asymptomatic individuals.
  • Complications can include renal issues like stones or bone problems such as fractures.

Purpose of the Study:

  • To outline the recommended diagnostic work-up for primary hyperparathyroidism.
  • To clarify which tests are essential and which are not routinely indicated.

Main Methods:

  • Comprehensive assessment of renal function, including glomerular filtration rate.
  • Measurement of 24-hour calciuria and screening for lithiasis risk factors.
  • Bone densitometry (spine, femur, radius) and imaging for vertebral fractures.

Main Results:

  • Recommended work-up includes renal function tests, calciuria, lithiasis screening, and bone density measurements.
  • Imaging for renal stones or nephrocalcinosis and X-rays for vertebral fractures are advised.
  • Routine screening for neurocognitive, quality of life, or cardiovascular issues is not standard.

Conclusions:

  • A thorough evaluation is crucial for primary hyperparathyroidism patients, focusing on renal and bone health.
  • Current guidelines do not support routine screening for non-consensual surgical indications like neurocognitive or cardiovascular symptoms.
