The Parathyroid Glands00:59

The Parathyroid Glands

3.1K
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...

Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

5.1K
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

3.2K
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

3.0K
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...

Chronic Kidney Disease III: Interprofessional Care

152
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Roles of Electrolytes: Calcium and Phosphate01:27

Roles of Electrolytes: Calcium and Phosphate

673
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...

Area of Science:

  • Endocrinology
  • Clinical Management
  • Medical Guidelines

Background:

  • Normocalcemic primary hyperparathyroidism (NPH) presents diagnostic and management challenges.
  • Current clinical guidelines lack specific, evidence-based recommendations for NPH.
  • This ambiguity impacts patient care and treatment strategies.

Purpose of the Study:

  • To develop a comprehensive clinical management algorithm for NPH.
  • To address the lack of evidence-based recommendations in current guidelines.
  • To provide a structured approach for NPH diagnosis and treatment.

Main Methods:

  • Exhaustive review of current medical literature on NPH.
  • Analysis of diagnostic criteria and differential diagnoses for NPH.
  • Evaluation of clinical manifestations, treatment indications, and follow-up schemes.

Main Results:

  • A proposed clinical management algorithm for NPH patients.
  • Detailed review of diagnostic and differential diagnostic criteria.
  • Consideration of surgical and medical treatment options, including preoperative localization and follow-up.

Conclusions:

  • The proposed algorithm offers a structured approach to NPH management.
  • Addresses the need for evidence-based recommendations in clinical practice.
  • Aims to improve patient outcomes through standardized care pathways.
