Hormones and Bone Tissue

Hormones and Bone Tissue

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 Glands

The Parathyroid Glands

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 producing...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Hyperthyroidism I: Introduction

Hyperthyroidism I: Introduction

Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

Hyperthyroidism II: Pathophysiology

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

Graves Disease II: Pathophysiology

Graves Disease II: Pathophysiology

Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...

Diagnosis of hyperparathyroidism.

H G Bone, W H Snyder, C Y Pak

Annual Review of Medicine

|January 1, 1977

Summary

Primary hyperparathyroidism, a condition of excess parathyroid hormone (PTH), requires consideration in diagnosing hypercalcemia and related disorders. Improved detection reveals subtler symptoms, aiding diagnosis through elevated calcium and PTH levels.

Area of Science:

Endocrinology
Nephrology
Gastroenterology

Background:

Hypersecretion of parathyroid hormone (PTH) can be primary or secondary to other conditions.
Primary hyperparathyroidism is a key consideration in diagnosing hypercalcemia, nephrolithiasis, metabolic bone disease, and gastrointestinal issues like pancreatitis and peptic-ulcer disease.
Clinical presentations are becoming less obvious due to advancements in diagnostic detection methods.

Purpose of the Study:

To outline the diagnostic considerations for primary hyperparathyroidism.
To highlight key biochemical and radiological findings supporting the diagnosis.
To discuss the importance of intraoperative assessment and future diagnostic advancements.

Main Methods:

Diagnosis relies on identifying elevated serum calcium levels, often accompanied by high serum PTH levels or increased urinary cyclic adenosine monophosphate (cAMP) excretion.

Supporting findings include hypophosphatemia, decreased renal tubular reabsorption of phosphorus, hypercalciuria, and characteristic radiographic changes.

Intraoperative assessment is crucial for differentiating between single-gland and multiglandular disease.

Main Results:

Elevated serum calcium is a near-universal finding in hyperparathyroidism.
The combination of hypercalcemia with elevated PTH or urinary cAMP strongly suggests the diagnosis.
While supportive, hypophosphatemia and radiographic findings are not essential for diagnosis.

Conclusions:

Primary hyperparathyroidism necessitates inclusion in the differential diagnosis for several common clinical presentations.
Accurate diagnosis is increasingly reliant on biochemical markers, particularly serum calcium and PTH levels.
Future advancements are anticipated in histopathology and PTH measurement techniques for improved diagnostic accuracy.
