Pathological processes of the PARATHYROID GLANDS. They usually manifest as hypersecretion or hyposecretion of PARATHYROID HORMONE that regulates the balance of CALCIUM; PHOSPHORUS; and MAGNESIUM in the body.
Tumors or cancer of the PARATHYROID GLANDS.
Two pairs of small oval-shaped glands located in the front and the base of the NECK and adjacent to the two lobes of THYROID GLAND. They secrete PARATHYROID HORMONE that regulates the balance of CALCIUM; PHOSPHORUS; and MAGNESIUM in the body.
A condition of abnormally elevated output of PARATHYROID HORMONE (or PTH) triggering responses that increase blood CALCIUM. It is characterized by HYPERCALCEMIA and BONE RESORPTION, eventually leading to bone diseases. PRIMARY HYPERPARATHYROIDISM is caused by parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. SECONDARY HYPERPARATHYROIDISM is increased PTH secretion in response to HYPOCALCEMIA, usually caused by chronic KIDNEY DISEASES.
A polypeptide hormone (84 amino acid residues) secreted by the PARATHYROID GLANDS which performs the essential role of maintaining intracellular CALCIUM levels in the body. Parathyroid hormone increases intracellular calcium by promoting the release of CALCIUM from BONE, increases the intestinal absorption of calcium, increases the renal tubular reabsorption of calcium, and increases the renal excretion of phosphates.
A benign epithelial tumor with a glandular organization.
A ubiquitously expressed, secreted protein with bone resorption and renal calcium reabsorption activities that are similar to PARATHYROID HORMONE. It does not circulate in appreciable amounts in normal subjects, but rather exerts its biological actions locally. Overexpression of parathyroid hormone-related protein by tumor cells results in humoral calcemia of malignancy.
A parathyroid hormone receptor subtype that recognizes both PARATHYROID HORMONE and PARATHYROID HORMONE-RELATED PROTEIN. It is a G-protein-coupled receptor that is expressed at high levels in BONE and in KIDNEY.
Cell surface proteins that bind PARATHYROID HORMONE with high affinity and trigger intracellular changes which influence the behavior of cells. Parathyroid hormone receptors on BONE; KIDNEY; and gastrointestinal cells mediate the hormone's role in calcium and phosphate homeostasis.
Excision of one or more of the parathyroid glands.
Abnormally high level of calcium in the blood.
Abnormally elevated PARATHYROID HORMONE secretion as a response to HYPOCALCEMIA. It is caused by chronic KIDNEY FAILURE or other abnormalities in the controls of bone and mineral metabolism, leading to various BONE DISEASES, such as RENAL OSTEODYSTROPHY.
A condition of abnormally elevated output of PARATHYROID HORMONE due to parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. It is characterized by the combination of HYPERCALCEMIA, phosphaturia, elevated renal 1,25-DIHYDROXYVITAMIN D3 synthesis, and increased BONE RESORPTION.
Reduction of the blood calcium below normal. Manifestations include hyperactive deep tendon reflexes, Chvostek's sign, muscle and abdominal cramps, and carpopedal spasm. (Dorland, 27th ed)

A polypeptide that consists of the 1-34 amino-acid fragment of human PARATHYROID HORMONE, the biologically active N-terminal region. The acetate form is given by intravenous infusion in the differential diagnosis of HYPOPARATHYROIDISM and PSEUDOHYPOPARATHYROIDISM. (Reynolds JEF(Ed): Martindale: The Extra Pharmacopoeia (electronic version). Micromedex, Inc, Englewood, CO, 1995)
A class of G-protein-coupled receptors that react to varying extracellular CALCIUM levels. Calcium-sensing receptors in the PARATHYROID GLANDS play an important role in the maintenance of calcium HOMEOSTASIS by regulating the release of PARATHYROID HORMONE. They differ from INTRACELLULAR CALCIUM-SENSING PROTEINS which sense intracellular calcium levels.
A condition caused by a deficiency of PARATHYROID HORMONE (or PTH). It is characterized by HYPOCALCEMIA and hyperphosphatemia. Hypocalcemia leads to TETANY. The acquired form is due to removal or injuries to the PARATHYROID GLANDS. The congenital form is due to mutations of genes, such as TBX1; (see DIGEORGE SYNDROME); CASR encoding CALCIUM-SENSING RECEPTOR; or PTH encoding parathyroid hormone.

Recurrent hyperparathyroidism. (1/70)

Recurrent hyperparathyroidism occurred in 11 of 295 patients from 10 months to 34 years after an initially successful operation. Seven patients with recurrent hyperparathyroidism had either multiple endocrine adenomatosis type I (MEA) or familial hyperparathyroidism (FHP), one patient had parathyroid cancer, and two patients had renal failure at the time of recurrence. Four of these patients ahd their initial operations elsewhere. Recurrence developed in 33% of patients with MEA or FHP but in only 0.4% of 242 patients without MEA or FHP. The presence of MEA or FHP was known before parathyroid exploration in 18 (86%) of the 21 patients. In patients with MEA or FHP, subtotal parathyroidectomy should be performed if there is more than one gland involved. Other patients should be treated by selective removal of an adenoma because recurrence is rare. Subtotal parathyroidectomy should be reserved for patients with diffuse hyperplasia.  (+info)

Calcimimetic NPS R-568 prevents parathyroid hyperplasia in rats with severe secondary hyperparathyroidism. (2/70)

Calcimimetic NPS R-568 prevents parathyroid hyperplasia in rats with severe secondary hyperparathyroidism. BACKGROUND: Secondary hyperparathyroidism (secondary HPT) in chronic renal insufficiency (CRI) is characterized by multiglandular hyperplasia. METHODS: In this study, we investigated the effects of the calcimimetic NPS R-568 on the parathyroid gland in rats with CRI induced by ligation of the renal arteries and severe secondary HPT induced by dietary phosphorus loading. Six days after surgery, high-phosphorus diet feeding was started, and NPS R-568 was administered to the rats for 56 days either by daily gavage (30 or 100 micromol/kg) or by continuous subcutaneous infusion (20 micromol/kg. day). RESULTS: After 54 days, serum PTH levels in vehicle-treated CRI rats were 1019 vs. 104 pg/mL in sham-operated controls. Infusion of NPS R-568 maintained serum PTH at levels comparable with those of sham-operated controls, whereas daily gavage also prevented much of the increase in CRI controls and decreased PTH levels intermittently in a dose-dependent fashion. Parathyroid gland enlargement was caused predominantly by hyperplasia. Total cell number per kg body wt was 3.5-fold higher in vehicle-treated CRI rats than in sham-operated controls. Both infusion and high-dose gavage of NPS R-568 completely prevented the increase in parathyroid cell number. CONCLUSION: These results demonstrate that the calcimimetic compound NPS R-568 can prevent both the increase in serum PTH levels and parathyroid hyperplasia in rats with CRI and severe secondary HPT. Moreover, these changes occurred despite decreases in serum 1, 25(OH)2D3 and increases in serum phosphate, suggesting a dominant role for the calcium receptor in regulating parathyroid cell proliferation.  (+info)

A possible autoimmune parathyroiditis following ozone inhalation. II. A histopathologic, ultrastructural, and immunofluorescent study. (3/70)

Histologic, ultrastructural, and immunofluorescent changes in the parathyroid glands of rabbits have been studied after 48 hours of ozone inhalation at a dosage of 0.75 ppm. The frequent changes observed included hyperplastic parathyroiditis followed by capillary proliferation and leukocytic infiltration. The progressive cytologic events consisted of the presence of eosinophilic leukocytes, reticuloendothelial and lymphocytic infiltration, disaggregation of the parenchyma, and interstitial edema. The ultrastructural changes consisted of degeneration of nuclei, atrophy of the mitochondria, dilatation and atrophy of the endoplasmic reticulum of the chief cells of the parathyroid gland, proliferation of the venous limb of the capillary network, and the prominent interstitial elements. The immunofluorescent techniques revealed positive immunologic response. These data suggest that ozone inhalation perhaps triggers an immune reaction which causes inflammatory injury to the parathyroid gland. The possibility that the modified functional chemical groups of the parathyroid gland act as autoantigen is discussed.  (+info)

Identification of somatic mutations of the MEN1 gene in sporadic endocrine tumours. (4/70)

Endocrine tumours of the pancreas, anterior pituitary or parathyroids arise either sporadically in the general population, or as a part of inherited syndromes such as multiple endocrine neoplasia type 1 (MEN 1). The mechanisms responsible for the development of sporadic endocrine lesions are not well understood, although loss of heterozygosity (LOH) of the MEN1 locus on chromosome 11q13 and somatic mutation of the MEN1 gene have been frequently associated with the development of MEN 1-type sporadic endocrine lesions. To further investigate the role of the MEN1 gene in sporadic endocrine tumorigenesis, we analysed DNA from 14 primary parathyroid lesions, 8 anterior pituitary tumours and 3 pancreatic tumours for the presence of somatic MEN1 gene mutations and LOH of seven microsatellite markers flanking the MEN1 locus. In addition, we similarly analysed 8 secondary parathyroid lesions which arose in patients with chronic renal failure. None of the patients studied had a family history of MEN 1. Three primary parathyroid lesions and one pancreatic tumour (glucagonoma) were found to have lost one allele at the MEN1 locus. Somatic mutations were identified by SSCP and sequence analysis in one of these parathyroid lesions (P320L) and in the glucagonoma (E179V). These results support previous findings that inactivation of the MEN1 tumour suppressor gene contributes to the development of sporadic MEN 1-type endocrine lesions but is not associated with the development of parathyroid hyperplasia seen in some renal failure patients.  (+info)

Langerhans cell histiocytosis involving the thyroid and parathyroid glands. (5/70)

Langerhans cell histiocytosis (LCH) is a rare illness, and the disease afflicting the thyroid gland is very uncommon, even in the presence of multisystem involvement. In this report, we document histologically, for the first time, concurrent involvement of the thyroid and parathyroid glands by LCH. A young Chinese woman with a history of diabetes insipidus and hypogonadism underwent a total thyroidectomy for enlarged thyroid gland secondary to LCH causing airway obstruction. Microscopic examination of the excised specimen disclosed CD1a- and S-100-positive LCH cells involving the thyroid and parathyroid glands. In a patient with LCH affecting the thyroid gland, parathyroid gland disease should be suspected when the serum calcium levels are depressed in association with an inappropriate serum parathyroid hormone level, such as a normal parathyroid hormone level in this case.  (+info)

Extracellular calcium-sensing receptor: structural and functional features and association with diseases. (6/70)

The recently cloned extracellular calcium-sensing receptor (CaR) is a G protein-coupled receptor that plays an essential role in the regulation of extracellular calcium homeostasis. This receptor is expressed in all tissues related to this control (parathyroid glands, thyroid C-cells, kidneys, intestine and bones) and also in tissues with apparently no role in the maintenance of extracellular calcium levels, such as brain, skin and pancreas. The CaR amino acid sequence is compatible with three major domains: a long and hydrophilic aminoterminal extracellular domain, where most of the activating and inactivating mutations described to date are located and where the dimerization process occurs, and the agonist-binding site is located, a hydrophobic transmembrane domain involved in the signal transduction mechanism from the extracellular domain to its respective G protein, and a carboxyterminal intracellular tail, with a well-established role for cell surface CaR expression and for signal transduction. CaR cloning was immediately followed by the association of genetic human diseases with inactivating and activating CaR mutations: familial hypocalciuric hypercalcemia and neonatal severe hyperparathyroidism are caused by CaR-inactivating mutations, whereas autosomal dominant hypoparathyroidism is secondary to CaR-activating mutations. Finally, we will comment on the development of drugs that modulate CaR function by either activating (calcimimetic drugs) or antagonizing it (calcilytic drugs), and on their potential therapeutic implications, such as medical control of specific cases of primary and uremic hyperparathyroidism with calcimimetic drugs and a potential treatment for osteoporosis with a calcilytic drug.  (+info)

The acute effect of chlorothiazide on serum-ionized calcium. Evidence for a parathyroid hormone-dependent mechanism. (7/70)

The acute effects of chlorothiazide (CTZ) on total (TSCA) and ionized (SCA-plus 2) serum calcium concentrations were studied in three groups of people: (a) eight subjects with normal parathyroid function; (b) six patients with hypoparathyroidism; and (c) two patients with hyperparathyroidism. Most subjects were studied on four occasions; at least 3 days intervened between studies on an individual subject. During each experiment the subject received an i.v. influsion of 5% dextrose in water at 1 ml/min from 8 a.m. to 4 p.m. Additions to the infusions were (a) none; (b) CTZ to deliver 3.33 mg/kg/h; (c) parathyroid extract to deliver 1 U/kg/h; or (d) both CTZ and parathyroid extract at the rates previously indicated. CTZ, when used, was added to the infusion at 10 a.m., parathyroid extract at 8 a.m. When CTZ was infused, the diuretic-induced losses of Na and water were replaced by i.v. infusion. In normal subjects 2 h after the start of CTZ infusion, there was a transient increase in SCA-plus 2 which coincided in time of day with a transient decrease in SCA-plus 2 in control experiments. At that time of day SCA-plus 2 was 4.18 plus or minus 0.12 mg/100 ml in control experiments and 4.56 plus or minus 0.08 in experiments with CTZ, P smaller than 0.025. The corresponding values for (TSCA) were 9.32 plus or minus 0.15 and 9.80 plus or minus 0.30, P smaller than 0.01. Such differences were not observed in the group with hypoparathyroidism. In the two patients with hyperparathyroidism, CTZ produced sustained increases in TSCA and SCA-plus 2. In normal subjects and those with hypoparathyroidism, CTZ plus parathyroid extract infusion resulted in sustained increases in both SCA-plus 2 and TSCA throughout the periods of observation when compared to experiments in which only parathyroid extract was infused, P smaller than 0.01 in all instances. The results suggest that the acute hypercalcemic action of CTZ requires the presence of circulating parathyroid hormone.  (+info)

Cosmetic result in thyroid surgery,. (8/70)

In a series of 306 consecutive patients who had thyroid or parathyroid surgery for benign or malignant lesions attention was paid to a technique in which particular emphasis was laid on meticulous haemostasis and suction drainage of the postoperative serosanguineous fluid. This not only reduced the morbidity associated with haematoma formation and infection but also contributed to a good cosmetic result.  (+info)

Parathyroid diseases refer to conditions that affect the parathyroid glands, which are small endocrine glands located in the neck, near or attached to the back surface of the thyroid gland. The primary function of the parathyroid glands is to produce and secrete parathyroid hormone (PTH), a crucial hormone that helps regulate calcium and phosphorus levels in the blood and bones.

There are four parathyroid glands, and they can develop various diseases, including:

1. Hyperparathyroidism: A condition where one or more parathyroid glands produce excessive amounts of PTH. This can lead to an imbalance in calcium and phosphorus levels, resulting in symptoms such as fatigue, weakness, bone pain, kidney stones, and increased risk of osteoporosis. Hyperparathyroidism can be primary (caused by a benign or malignant tumor in the parathyroid gland), secondary (due to chronic kidney disease or vitamin D deficiency), or tertiary (when secondary hyperparathyroidism becomes autonomous and continues even after correcting the underlying cause).
2. Hypoparathyroidism: A condition where the parathyroid glands do not produce enough PTH, leading to low calcium levels in the blood (hypocalcemia) and high phosphorus levels (hyperphosphatemia). Symptoms of hypoparathyroidism may include muscle spasms, tingling sensations in the fingers, toes, or lips, anxiety, cataracts, and seizures. Hypoparathyroidism can be caused by surgical removal of the parathyroid glands, autoimmune disorders, radiation therapy, or genetic conditions.
3. Parathyroid tumors: Abnormal growths in the parathyroid glands can lead to hyperparathyroidism. Benign tumors (adenomas) are the most common cause of primary hyperparathyroidism. Malignant tumors (carcinomas) are rare but can also occur, leading to more severe symptoms and a worse prognosis.
4. Parathyroid dysfunction in genetic disorders: Some genetic syndromes, such as multiple endocrine neoplasia type 1 (MEN1), multiple endocrine neoplasia type 2A (MEN2A), and hyperparathyroidism-jaw tumor syndrome (HPT-JT), can involve parathyroid gland abnormalities, leading to hyperparathyroidism or other related conditions.

Proper diagnosis and management of parathyroid disorders are crucial for maintaining optimal calcium homeostasis and preventing complications associated with hypocalcemia or hypercalcemia. Treatment options may include surgery, medication, dietary modifications, and monitoring hormone levels.

Parathyroid neoplasms refer to abnormal growths in the parathyroid glands, which are small endocrine glands located in the neck, near or within the thyroid gland. These neoplasms can be benign (non-cancerous) or malignant (cancerous).

Benign parathyroid neoplasms are typically called parathyroid adenomas and are the most common type of parathyroid disorder. They result in overproduction of parathyroid hormone (PTH), leading to a condition known as primary hyperparathyroidism. Symptoms may include kidney stones, osteoporosis, fatigue, depression, and abdominal pain.

Malignant parathyroid neoplasms are called parathyroid carcinomas. They are rare but more aggressive than adenomas, with a higher risk of recurrence and metastasis. Symptoms are similar to those of benign neoplasms but may also include hoarseness, difficulty swallowing, and enlarged lymph nodes in the neck.

It is important to note that parathyroid neoplasms can only be definitively diagnosed through biopsy or surgical removal and subsequent histopathological examination.

The parathyroid glands are four small endocrine glands located in the neck, usually near or behind the thyroid gland. They secrete parathyroid hormone (PTH), which plays a critical role in regulating calcium and phosphate levels in the blood and bones. PTH helps maintain the balance of these minerals by increasing the absorption of calcium from food in the intestines, promoting reabsorption of calcium in the kidneys, and stimulating the release of calcium from bones when needed. Additionally, PTH decreases the excretion of calcium through urine and reduces phosphate reabsorption in the kidneys, leading to increased phosphate excretion. Disorders of the parathyroid glands can result in conditions such as hyperparathyroidism (overactive glands) or hypoparathyroidism (underactive glands), which can have significant impacts on calcium and phosphate homeostasis and overall health.

Hyperparathyroidism is a condition in which the parathyroid glands produce excessive amounts of parathyroid hormone (PTH). There are four small parathyroid glands located in the neck, near or within the thyroid gland. They release PTH into the bloodstream to help regulate the levels of calcium and phosphorus in the body.

In hyperparathyroidism, overproduction of PTH can lead to an imbalance in these minerals, causing high blood calcium levels (hypercalcemia) and low phosphate levels (hypophosphatemia). This can result in various symptoms such as fatigue, weakness, bone pain, kidney stones, and cognitive issues.

There are two types of hyperparathyroidism: primary and secondary. Primary hyperparathyroidism occurs when there is a problem with one or more of the parathyroid glands, causing them to become overactive and produce too much PTH. Secondary hyperparathyroidism develops as a response to low calcium levels in the body due to conditions like vitamin D deficiency, chronic kidney disease, or malabsorption syndromes.

Treatment for hyperparathyroidism depends on the underlying cause and severity of symptoms. In primary hyperparathyroidism, surgery to remove the overactive parathyroid gland(s) is often recommended. For secondary hyperparathyroidism, treating the underlying condition and managing calcium levels with medications or dietary changes may be sufficient.

Parathyroid hormone (PTH) is a polypeptide hormone that plays a crucial role in the regulation of calcium and phosphate levels in the body. It is produced and secreted by the parathyroid glands, which are four small endocrine glands located on the back surface of the thyroid gland.

The primary function of PTH is to maintain normal calcium levels in the blood by increasing calcium absorption from the gut, mobilizing calcium from bones, and decreasing calcium excretion by the kidneys. PTH also increases phosphate excretion by the kidneys, which helps to lower serum phosphate levels.

In addition to its role in calcium and phosphate homeostasis, PTH has been shown to have anabolic effects on bone tissue, stimulating bone formation and preventing bone loss. However, chronic elevations in PTH levels can lead to excessive bone resorption and osteoporosis.

Overall, Parathyroid Hormone is a critical hormone that helps maintain mineral homeostasis and supports healthy bone metabolism.

An adenoma is a benign (noncancerous) tumor that develops from glandular epithelial cells. These types of cells are responsible for producing and releasing fluids, such as hormones or digestive enzymes, into the surrounding tissues. Adenomas can occur in various organs and glands throughout the body, including the thyroid, pituitary, adrenal, and digestive systems.

Depending on their location, adenomas may cause different symptoms or remain asymptomatic. Some common examples of adenomas include:

1. Colorectal adenoma (also known as a polyp): These growths occur in the lining of the colon or rectum and can develop into colorectal cancer if left untreated. Regular screenings, such as colonoscopies, are essential for early detection and removal of these polyps.
2. Thyroid adenoma: This type of adenoma affects the thyroid gland and may result in an overproduction or underproduction of hormones, leading to conditions like hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid).
3. Pituitary adenoma: These growths occur in the pituitary gland, which is located at the base of the brain and controls various hormonal functions. Depending on their size and location, pituitary adenomas can cause vision problems, headaches, or hormonal imbalances that affect growth, reproduction, and metabolism.
4. Liver adenoma: These rare benign tumors develop in the liver and may not cause any symptoms unless they become large enough to press on surrounding organs or structures. In some cases, liver adenomas can rupture and cause internal bleeding.
5. Adrenal adenoma: These growths occur in the adrenal glands, which are located above the kidneys and produce hormones that regulate stress responses, metabolism, and blood pressure. Most adrenal adenomas are nonfunctioning, meaning they do not secrete excess hormones. However, functioning adrenal adenomas can lead to conditions like Cushing's syndrome or Conn's syndrome, depending on the type of hormone being overproduced.

It is essential to monitor and manage benign tumors like adenomas to prevent potential complications, such as rupture, bleeding, or hormonal imbalances. Treatment options may include surveillance with imaging studies, medication to manage hormonal issues, or surgical removal of the tumor in certain cases.

Parathyroid Hormone-Related Protein (PTHrP) is a protein that is encoded by the PTHLH gene in humans. It is structurally similar to parathyroid hormone (PTH) and was initially identified due to its role in humoral hypercalcemia of malignancy, a condition characterized by high levels of calcium in the blood caused by certain types of cancer.

PTHrP has a variety of functions in the body, including regulation of calcium and phosphate homeostasis, cell growth and differentiation, and bone metabolism. It acts through a specific G protein-coupled receptor called the PTH/PTHrP receptor, which is found in many tissues throughout the body, including bone, kidney, and cartilage.

In contrast to PTH, which is primarily produced by the parathyroid glands and regulates calcium levels in the blood, PTHrP is produced by many different types of cells throughout the body. Its expression is regulated in a tissue-specific manner, and its functions can vary depending on the context in which it is produced.

Overall, PTHrP plays important roles in normal physiology as well as in various disease states, including cancer, bone disorders, and developmental abnormalities.

Parathyroid Hormone Receptor Type 1 (PTH1R) is a type of G protein-coupled receptor that binds to parathyroid hormone (PTH) and parathyroid hormone-related peptide (PTHrP). It is primarily found in bone and kidney cells.

The activation of PTH1R by PTH or PTHrP leads to a series of intracellular signaling events that regulate calcium homeostasis, bone metabolism, and renal function. In the bone, PTH1R stimulates the release of calcium from bone matrix into the bloodstream, while in the kidney, it increases the reabsorption of calcium in the distal tubule and inhibits phosphate reabsorption.

Mutations in the gene encoding PTH1R can lead to several genetic disorders, such as Blomstrand chondrodysplasia, Jansen metaphyseal chondrodysplasia, and hypoparathyroidism type 1B. These conditions are characterized by abnormalities in bone development, growth, and mineralization.

Parathyroid hormone (PTH) receptors are a type of cell surface receptor that bind to and respond to parathyroid hormone, a hormone secreted by the parathyroid glands. These receptors are found in various tissues throughout the body, including bone, kidney, and intestine.

The PTH receptor is a member of the G protein-coupled receptor (GPCR) family, which consists of seven transmembrane domains. When PTH binds to the receptor, it activates a signaling pathway that leads to increased calcium levels in the blood. In bone, activation of PTH receptors stimulates the release of calcium from bone matrix, while in the kidney, it increases the reabsorption of calcium from the urine and decreases the excretion of phosphate.

In the intestine, PTH receptors play a role in the regulation of vitamin D metabolism, which is important for calcium absorption. Overall, the activation of PTH receptors helps to maintain normal calcium levels in the blood and regulate bone metabolism.

Parathyroidectomy is a surgical procedure for the removal of one or more of the parathyroid glands. These glands are located in the neck and are responsible for producing parathyroid hormone (PTH), which helps regulate the levels of calcium and phosphorus in the body.

Parathyroidectomy is typically performed to treat conditions such as hyperparathyroidism, where one or more of the parathyroid glands become overactive and produce too much PTH. This can lead to high levels of calcium in the blood, which can cause symptoms such as weakness, fatigue, bone pain, kidney stones, and mental confusion.

There are different types of parathyroidectomy procedures, including:

* Partial parathyroidectomy: removal of one or more, but not all, of the parathyroid glands.
* Total parathyroidectomy: removal of all four parathyroid glands.
* Subtotal parathyroidectomy: removal of three and a half of the four parathyroid glands, leaving a small portion of one gland to prevent hypoparathyroidism (a condition where the body produces too little PTH).

The choice of procedure depends on the underlying condition and its severity. After the surgery, patients may need to have their calcium levels monitored and may require calcium and vitamin D supplements to maintain normal calcium levels in the blood.

Hypercalcemia is a medical condition characterized by an excess of calcium ( Ca2+ ) in the blood. While the normal range for serum calcium levels is typically between 8.5 to 10.2 mg/dL (milligrams per deciliter) or 2.14 to 2.55 mmol/L (millimoles per liter), hypercalcemia is generally defined as a serum calcium level greater than 10.5 mg/dL or 2.6 mmol/L.

Hypercalcemia can result from various underlying medical disorders, including primary hyperparathyroidism, malignancy (cancer), certain medications, granulomatous diseases, and excessive vitamin D intake or production. Symptoms of hypercalcemia may include fatigue, weakness, confusion, memory loss, depression, constipation, nausea, vomiting, increased thirst, frequent urination, bone pain, and kidney stones. Severe or prolonged hypercalcemia can lead to serious complications such as kidney failure, cardiac arrhythmias, and calcification of soft tissues. Treatment depends on the underlying cause and severity of the condition.

Secondary hyperparathyroidism is a condition characterized by an overproduction of parathyroid hormone (PTH) from the parathyroid glands due to hypocalcemia (low levels of calcium in the blood). This condition is usually a result of chronic kidney disease, where the kidneys fail to convert vitamin D into its active form, leading to decreased absorption of calcium in the intestines. The body responds by increasing PTH production to maintain normal calcium levels, but over time, this results in high PTH levels and associated complications such as bone disease, kidney stones, and cardiovascular calcification.

Primary hyperparathyroidism is a medical condition characterized by excessive secretion of parathyroid hormone (PTH) from one or more of the parathyroid glands in the neck. These glands are normally responsible for regulating calcium levels in the body by releasing PTH, which helps to maintain an appropriate balance of calcium and phosphate in the bloodstream.

In primary hyperparathyroidism, the parathyroid gland(s) become overactive and produce too much PTH, leading to elevated calcium levels (hypercalcemia) in the blood. This can result in a variety of symptoms, such as fatigue, weakness, bone pain, kidney stones, and cognitive impairment, although some individuals may not experience any symptoms at all.

The most common cause of primary hyperparathyroidism is a benign tumor called an adenoma that develops in one or more of the parathyroid glands. In rare cases, primary hyperparathyroidism can be caused by cancer of the parathyroid gland(s) or by enlargement of all four glands (four-gland hyperplasia). Treatment typically involves surgical removal of the affected parathyroid gland(s), which is usually curative.

Hypocalcemia is a medical condition characterized by an abnormally low level of calcium in the blood. Calcium is a vital mineral that plays a crucial role in various bodily functions, including muscle contraction, nerve impulse transmission, and bone formation. Normal calcium levels in the blood usually range from 8.5 to 10.2 milligrams per deciliter (mg/dL). Hypocalcemia is typically defined as a serum calcium level below 8.5 mg/dL or, when adjusted for albumin (a protein that binds to calcium), below 8.4 mg/dL (ionized calcium).

Hypocalcemia can result from several factors, such as vitamin D deficiency, hypoparathyroidism (underactive parathyroid glands), kidney dysfunction, certain medications, and severe magnesium deficiency. Symptoms of hypocalcemia may include numbness or tingling in the fingers, toes, or lips; muscle cramps or spasms; seizures; and, in severe cases, cognitive impairment or cardiac arrhythmias. Treatment typically involves correcting the underlying cause and administering calcium and vitamin D supplements to restore normal calcium levels in the blood.

The parathyroid hormone type 2 receptor (PTH2R) is a gene that encodes for a G protein-coupled receptor found primarily in the central nervous system. It is a receptor for parathyroid hormone-related peptide (PTHrP), a hormone involved in calcium homeostasis, and tuberoinfundibular peptide of 39 residues (TIP39), a neuropeptide involved in pain regulation.

Unlike the parathyroid hormone type 1 receptor (PTH1R), which is widely expressed and mediates the actions of PTH on bone and kidney, PTH2R has a more limited distribution and its physiological role is not as well understood. However, it is known to play a role in regulating pain sensitivity, anxiety, and food intake.

It's important to note that while PTH and PTHrP can bind to both PTH1R and PTH2R, they have different affinities and elicit distinct signaling pathways depending on the receptor they bind to.

Teriparatide is a synthetic form of parathyroid hormone (PTH), which is a natural hormone produced by the parathyroid glands in the body. The medication contains the active fragment of PTH, known as 1-34 PTH, and it is used in medical treatment to stimulate new bone formation and increase bone density.

Teriparatide is primarily prescribed for the management of osteoporosis in postmenopausal women and men with a high risk of fractures who have not responded well to other osteoporosis therapies, such as bisphosphonates. It is administered via subcutaneous injection, typically once daily.

By increasing bone formation and reducing bone resorption, teriparatide helps improve bone strength and structure, ultimately decreasing the risk of fractures in treated individuals. The medication's effects on bone metabolism can lead to improvements in bone mineral density (BMD) and microarchitecture, making it an essential tool for managing severe osteoporosis and reducing fracture risk.

Calcium-sensing receptors (CaSR) are a type of G protein-coupled receptor that play a crucial role in the regulation of extracellular calcium homeostasis. They are widely expressed in various tissues, including the parathyroid gland, kidney, and bone.

The primary function of CaSR is to detect changes in extracellular calcium concentrations and transmit signals to regulate the release of parathyroid hormone (PTH) from the parathyroid gland. When the concentration of extracellular calcium increases, CaSR is activated, which leads to a decrease in PTH secretion, thereby preventing further elevation of calcium levels. Conversely, when calcium levels decrease, CaSR is inhibited, leading to an increase in PTH release and restoration of normal calcium levels.

In addition to regulating calcium homeostasis, CaSR also plays a role in other physiological processes, including cell proliferation, differentiation, and apoptosis. Dysregulation of CaSR has been implicated in various diseases, such as hyperparathyroidism, hypoparathyroidism, and cancer. Therefore, understanding the function and regulation of CaSR is essential for developing new therapeutic strategies to treat these conditions.

Hypoparathyroidism is a medical condition characterized by decreased levels or insufficient function of parathyroid hormone (PTH), which is produced and released by the parathyroid glands. These glands are located in the neck, near the thyroid gland, and play a crucial role in regulating calcium and phosphorus levels in the body.

In hypoparathyroidism, low PTH levels result in decreased absorption of calcium from the gut, increased excretion of calcium through the kidneys, and impaired regulation of bone metabolism. This leads to low serum calcium levels (hypocalcemia) and high serum phosphorus levels (hyperphosphatemia).

Symptoms of hypoparathyroidism can include muscle cramps, spasms, or tetany (involuntary muscle contractions), numbness or tingling sensations in the fingers, toes, and around the mouth, fatigue, weakness, anxiety, cognitive impairment, and in severe cases, seizures. Hypoparathyroidism can be caused by various factors, including surgical removal or damage to the parathyroid glands, autoimmune disorders, radiation therapy, genetic defects, or low magnesium levels. Treatment typically involves calcium and vitamin D supplementation to maintain normal serum calcium levels and alleviate symptoms. In some cases, recombinant PTH (Natpara) may be prescribed as well.
