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...

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...

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...

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...

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...

Skeleton and Calcium Homeostasis

Skeleton and Calcium Homeostasis

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.

Area of Science:

Endocrinology
Nuclear Medicine
Surgical Pathology

Background:

Primary Hyperparathyroidism (PHPT) exhibits diverse clinical manifestations, frequently leading to initial misdiagnosis.
Ectopic parathyroid glands, resulting from developmental migration anomalies, can present diagnostic challenges, mimicking thyroid nodules or evading surgical localization.
Fine needle aspiration cytology may be inconclusive due to cytological similarities between thyroid and parathyroid tissues.

Observation:

Three cases of Primary Hyperparathyroidism with parathyroid adenomas in ectopic locations were identified.
Pre-operative nuclear imaging scintigraphy was crucial in accurately localizing these ectopic adenomas.
The diagnostic utility of nuclear imaging in identifying parathyroid tumors in unusual locations was highlighted.

Findings:

Nuclear imaging scintigraphy demonstrates high accuracy (90%) in localizing parathyroid tumors.
Accurate localization by nuclear imaging significantly simplifies surgical planning and execution.
Ectopic parathyroid adenomas pose diagnostic difficulties, often requiring advanced imaging for definitive diagnosis.

Implications:

Early and accurate diagnosis of PHPT, especially with ectopic glands, is essential for timely intervention.
Nuclear imaging is a valuable tool for overcoming diagnostic hurdles in cases of ectopic parathyroid adenomas.
Improved diagnostic strategies can lead to better surgical outcomes and patient management for PHPT.
