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.
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 hereditary syndrome clinically similar to HYPOPARATHYROIDISM. It is characterized by HYPOCALCEMIA; HYPERPHOSPHATEMIA; and associated skeletal development impairment and caused by failure of response to PARATHYROID HORMONE rather than deficiencies. A severe form with resistance to multiple hormones is referred to as Type 1a and is associated with maternal mutant allele of the ALPHA CHAIN OF STIMULATORY G PROTEIN.
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.
Condition with a variable constellation of phenotypes due to deletion polymorphisms at chromosome location 22q11. It encompasses several syndromes with overlapping abnormalities including the DIGEORGE SYNDROME, VELOCARDIOFACIAL SYNDROME, and CONOTRUNCAL AMOMALY FACE SYNDROME. In addition, variable developmental problems and schizoid features are also associated with this syndrome. (From BMC Med Genet. 2009 Feb 25;10:16) Not all deletions at 22q11 result in the 22q11deletion syndrome.
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.
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.
Surgical removal of the thyroid gland. (Dorland, 28th ed)
Congenital syndrome characterized by a wide spectrum of characteristics including the absence of the THYMUS and PARATHYROID GLANDS resulting in T-cell immunodeficiency, HYPOCALCEMIA, defects in the outflow tract of the heart, and craniofacial anomalies.
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 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 thiazide diuretic with properties similar to those of HYDROCHLOROTHIAZIDE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p825)
Autoimmune diseases affecting multiple endocrine organs. Type I is characterized by childhood onset and chronic mucocutaneous candidiasis (CANDIDIASIS, CHRONIC MUCOCUTANEOUS), while type II exhibits any combination of adrenal insufficiency (ADDISON'S DISEASE), lymphocytic thyroiditis (THYROIDITIS, AUTOIMMUNE;), HYPOPARATHYROIDISM; and gonadal failure. In both types organ-specific ANTIBODIES against a variety of ENDOCRINE GLANDS have been detected. The type II syndrome differs from type I in that it is associated with HLA-A1 and B8 haplotypes, onset is usually in adulthood, and candidiasis is not present.
A non-metal element that has the atomic symbol P, atomic number 15, and atomic weight 31. It is an essential element that takes part in a broad variety of biochemical reactions.
A specific pair of GROUP G CHROMOSOMES of the human chromosome classification.
A dyskinesia characterized by an inability to maintain the fingers, toes, tongue, or other body parts in a stable position, resulting in continuous slow, sinusoidal, and flowing involuntary movements. This condition is frequently accompanied by CHOREA, where it is referred to as choreoathetosis. Athetosis may occur as a manifestation of BASAL GANGLIA DISEASES or DRUG TOXICITY. (From Adams et al., Principles of Neurology, 6th ed, p76)
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 vitamin that includes both CHOLECALCIFEROLS and ERGOCALCIFEROLS, which have the common effect of preventing or curing RICKETS in animals. It can also be viewed as a hormone since it can be formed in SKIN by action of ULTRAVIOLET RAYS upon the precursors, 7-dehydrocholesterol and ERGOSTEROL, and acts on VITAMIN D RECEPTORS to regulate CALCIUM in opposition to PARATHYROID HORMONE.
Abnormally high level of calcium in the blood.
A basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
Hydroxy analogs of vitamin D 3; (CHOLECALCIFEROL); including CALCIFEDIOL; CALCITRIOL; and 24,25-DIHYDROXYVITAMIN D 3.
A VITAMIN D that can be regarded as a reduction product of vitamin D2.
The physiologically active form of vitamin D. It is formed primarily in the kidney by enzymatic hydroxylation of 25-hydroxycholecalciferol (CALCIFEDIOL). Its production is stimulated by low blood calcium levels and parathyroid hormone. Calcitriol increases intestinal absorption of calcium and phosphorus, and in concert with parathyroid hormone increases bone resorption.
Excision of one or more of the parathyroid glands.
Congenital or acquired paralysis of one or both VOCAL CORDS. This condition is caused by defects in the CENTRAL NERVOUS SYSTEM, the VAGUS NERVE and branches of LARYNGEAL NERVES. Common symptoms are VOICE DISORDERS including HOARSENESS or APHONIA.
An enlarged THYROID GLAND with at least 50% of the gland situated behind the STERNUM. It is an unusual presentation of an intrathoracic goiter. Substernal goiters frequently cause compression on the TRACHEA leading to deviation, narrowing, and respiratory symptoms.
Therapeutic use of hormones to alleviate the effects of hormone deficiency.
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.
Involuntary, forcible, rapid, jerky movements that may be subtle or become confluent, markedly altering normal patterns of movement. Hypotonia and pendular reflexes are often associated. Conditions which feature recurrent or persistent episodes of chorea as a primary manifestation of disease are referred to as CHOREATIC DISORDERS. Chorea is also a frequent manifestation of BASAL GANGLIA DISEASES.
Carbonic acid calcium salt (CaCO3). An odorless, tasteless powder or crystal that occurs in nature. It is used therapeutically as a phosphate buffer in hemodialysis patients and as a calcium supplement.
The calcium salt of gluconic acid. The compound has a variety of uses, including its use as a calcium replenisher in hypocalcemic states.

Primary hypomagnesemia caused by isolated magnesium malabsorption: atypical case in adult. (1/260)

Isolated magnesium malabsorption is a rare disorder, which bas been described in no more than 30 patients worldwide. Patients with this disorder typically present with convulsion and diarrhea in early infancy. Hypomagnesemia and hypocalcemia were found in a 35-year-old man with muscle cramps, who bad been diagnosed as primary hypoparathyroidism. Oral magnesium therapy corrected the low serum calcium, magnesium and parathyroid hormone levels. We report an atypical case of isolated magnesium malabsorption in an adult.  (+info)

New technique of parathyroidectomy to prevent parathyromatosis and hypoparathyroidism. (2/260)

A 54-year-old woman with end-stage renal disease and on haemodialysis for 4 years developed severe secondary hyperparathyroidism and was operated upon. The two upper and the largest lower parathyroid glands were resected. The right lower gland was dissected from the lower pole of the thyroid and, by gently pulling upwards, the lateral walls were dissected using electrocautery. The lower aspect of the gland maintained the blood supply through small mediastinal and thymic vessels of the neopedicle, which allowed its mobilization to a more superficial plane. Because of the large size of the gland, the part opposite to the neopedicle was resected and the cutting surface was sealed with fibrin adhesive. Pre-thyroidal muscles were reapproximated and the remnant of the parathyroid gland was pulled out through a small hole in the inferior part of the midline and sutured with fine silk to the muscle. The gland was therefore placed in a subcutaneous position in the lowest part of the operative field just above the sternal border. The postoperative course was uneventful and, 8 months after surgery, the patient maintains a normal parathyroid function.  (+info)

Radioimmunoassay for human calcitonin employing synthetic calcitonin M: its clinical application. (3/260)

A sensitive and reliable radioimmunoassay for human calcitonin was described and applied to preliminary clinical studies. 125I-labelled synthetic human calcitonin M was purified by gel filtration with Sephadex G-25 and G-100. A nonequilibrium incubation system was applied at the final volume of incubation mixture of 500 mul, in which pooled plasma from normal subjects or hormone free serum was used as carrier protein at 20% incubation mixture. Dextran T 40 coated charcoal, resuspended in 1% bovine serum albumin buffer, was used for the separation of free from bound tracer. This showed the least nonspecific adsorption of tracer to charcoal. The assay was sensitive to 0.1 ng per milliliter of plasma. Recovery of synthetic human calcitonin added to plasma was found to be 101% (S. D., +/- 8). Diluted plasma from a patient with medullary thyroid carcinoma showed a dilution curve parallel to standards. Basal calcitonin levels were less than 0.3 ng/ml in normal subjects. Relatively high values were found in patients with chronic renal failure and in patients with malignant tumors. Extremely elevated values were found in patients with medullary thyroid carcinoma. Provocative calcium infusion tests were also performed.  (+info)

An HDR (hypoparathyroidism, deafness, renal dysplasia) syndrome locus maps distal to the DiGeorge syndrome region on 10p13/14. (4/260)

Partial monosomy 10p is a rare chromosomal condition and a significant proportion of patients show features of DiGeorge syndrome (DGS) and velocardiofacial syndrome (VCFS). A critical haploinsufficiency region for DGS/VCFS was defined on 10p (DGCR2). We performed molecular deletion analysis of two further patients with partial monosomy 10p, who showed hypoparathyroidism, deafness, and renal dysplasia or renal insufficiency, but no cardiac defect, cleft palate, or reduced T cell levels. Previously, the combination of hypoparathyroidism, deafness, and renal dysplasia has been proposed to represent a specific syndrome (MIM 146255) under the acronym HDR. In addition to the two patients in this report, at least four published cases with partial monosomy 10p show the triad of HDR and 14 other patients present with at least two of the three features. We therefore conclude that HDR syndrome can be associated with partial monosomy 10p. Based on molecular deletion analysis and the clinical data, we suggest that the DGS/VCFS phenotype associated with 10p deletion can be considered as a contiguous gene syndrome owing to haploinsufficiency of two different regions. Hemizygosity of the proximal region, designated DGCR2, can cause cardiac defect and T cell deficiency. Hemizygosity of the distal region, designated HDR1, can cause hypoparathyroidism and in addition sensorineuronal deafness and renal dysplasia/insufficiency or a subset of this triad.  (+info)

Prevalence of idiopathic hypoparathyroidism and pseudohypoparathyroidism in Japan. (5/260)

A nationwide epidemiologic survey of idiopathic hypoparathyroidism and pseudohypoparathyroidism was conducted in 1998 to clarify the prevalence of the two disorders in Japan. From a total of 14,100 departments of pediatrics, internal medicine, neurology, and endocrinology in whole Japan, 2952 (20.9%) study departments were selected at random. Of these departments receiving the first questionnaire, 1855 (62.8%) responded. From these departments 390 patients with idiopathic hypoparathyroidism and 203 with pseudohypoparathyroidism who visited the hospitals in 1997 were reported. The total numbers of patients were estimated to be 900 (690-1100) for idiopathic hypoparathyroidism and 430 (330-520) for pseudohypoparathyroidism (95% confidence intervals in parentheses). Using these data, the period prevalence of the diseases were 7.2 (5.5-8.8) per million population in idiopathic hypoparathyroidism, and 3.4 (2.6-4.2) in pseudohypoparathyroidism (95% confidence intervals in parentheses).  (+info)

Diabetes mellitus, deafness, muscle weakness and hypocalcemia in a patient with an A3243G mutation of the mitochondrial DNA. (6/260)

In a 54-year-old woman with diabetes mellitus, hearing loss, muscle weakness and hypocalcemia, caused by idiopathic hypoparathyroidism, an A to G transition at the nucleotide position of 3243 (A3243G mutation) was found in the mitochondrial DNA from her leukocytes. Clinical features of diabetes mellitus and hearing loss in association with the A3243G mutation are compatible with a diagnosis of maternally inherited diabetes and deafness (MIDD). Although hypoparathyroidism is rarely seen in MIDD, we consider that hypoparathyroidism in this patient is a possible phenotype caused by the A3243G mutation of mitochondrial DNA.  (+info)

DiGeorge syndrome with Graves' disease: A case report. (7/260)

DiGeorge syndrome (DGS) is characterized by aplasia or hypoplasia of the thymus and parathyroid glands, cardiac defects and anomaly face. This syndrome is usually associated with hypocalcemia resulting from hypoparathyroidism. In most cases the initial symptom is tetany caused by hypocalcemia within 24-48 hours after birth, with symptoms by immune abnormality appearing later. We report a woman who passed with no symptoms before age 18 and was diagnosed DiGeorge syndrome by tetany with developing auto-immune thyroid disease (Graves' disease). She had surgery for intraventricular septal defect at age 3, hypoparathyroidism, decrease of T cells in peripheral blood and the deletion of the 22nd chromosome long arm (22q11.2). It is supposed that abnormalities of immune function of this case are not complete as indicated by complicating of Graves' disease, and contributing to her long-term survival.  (+info)

Hypoparathyroidism unmasked by alendronate. (8/260)

The case of an elderly woman is reported in whom alendronate, given for osteoporosis, led to severe hypocalcaemia a few days after starting the drug treatment. This was caused by the unmasking of previously unrecognised hypoparathyroidism.  (+info)

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.

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.

Pseudohypoparathyroidism (PHP) is a rare genetic disorder characterized by the body's resistance to the action of parathyroid hormone (PTH), leading to hypocalcemia (low serum calcium levels) and hyperphosphatemia (high serum phosphate levels). Despite normal or elevated PTH levels, target organs such as the kidneys and bones do not respond appropriately to its actions.

There are several types of PHP, with the most common being type Ia, which is caused by mutations in the GNAS gene. This gene provides instructions for making a protein called the alpha-subunit of the stimulatory G protein (Gs-alpha), which plays a crucial role in transmitting signals within cells. In PHP type Ia, there is a reduced amount or functionally impaired Gs-alpha protein, leading to resistance to PTH and other hormones that use this signaling pathway, such as thyroid-stimulating hormone (TSH) and gonadotropins.

PHP type Ia patients often exhibit physical features known as Albright's hereditary osteodystrophy (AHO), including short stature, round face, obesity, brachydactyly (shortened fingers and toes), and ectopic ossifications (formation of bone in abnormal places). However, it is important to note that not all individuals with AHO have PHP, and not all PHP patients display AHO features.

PHP type Ib is another common form of the disorder, characterized by PTH resistance without the physical manifestations of AHO. This type is caused by mutations in the STX16 gene or other genes involved in the intracellular trafficking of Gs-alpha protein.

Pseudohypoparathyroidism should be differentiated from hypoparathyroidism, a condition where there is an insufficient production or secretion of PTH by the parathyroid glands, leading to similar biochemical abnormalities but without resistance to PTH action.

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.

22q11 Deletion Syndrome, also known as DiGeorge Syndrome or Velocardiofacial Syndrome, is a genetic disorder caused by the deletion of a small piece of chromosome 22 at a specific location (q11.2). This deletion results in the poor development of several body systems, including the following:

* The third and fourth pharyngeal pouches, which give rise to various structures in the neck, such as the parathyroid glands and thymus. As a result, affected individuals often have hypocalcemia (low levels of calcium in the blood) due to decreased parathyroid hormone production, and may have immune deficiencies due to abnormal or missing thymus tissue.
* The fourth pharyngeal arch, which forms parts of the aortic arch, the cranial base, and the neck. This can lead to congenital heart defects, such as tetralogy of Fallot or interrupted aortic arch.
* The branchial arches, which contribute to the formation of the face and neck. This can result in distinctive facial features, such as a prominent nasal bridge, hooded eyelids, a small jaw, and low-set ears.

The severity of 22q11 Deletion Syndrome can vary widely, even among members of the same family. Common symptoms include heart defects, palate abnormalities, immune deficiencies, developmental delays, learning disabilities, behavioral problems, and hearing loss. Some individuals with this syndrome may also have psychiatric disorders, such as schizophrenia or anxiety disorders.

Treatment for 22q11 Deletion Syndrome typically involves a multidisciplinary approach, addressing each of the affected body systems. For example, heart defects may require surgical repair, while immune deficiencies may be managed with medications or thymus transplantation. Calcium supplements and vitamin D may be prescribed to treat hypocalcemia. Speech therapy, occupational therapy, and special education services can help address developmental delays and learning disabilities.

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.

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.

Thyroidectomy is a surgical procedure where all or part of the thyroid gland is removed. The thyroid gland is a butterfly-shaped endocrine gland located in the neck, responsible for producing hormones that regulate metabolism, growth, and development.

There are different types of thyroidectomy procedures, including:

1. Total thyroidectomy: Removal of the entire thyroid gland.
2. Partial (or subtotal) thyroidectomy: Removal of a portion of the thyroid gland.
3. Hemithyroidectomy: Removal of one lobe of the thyroid gland, often performed to treat benign solitary nodules or differentiated thyroid cancer.

Thyroidectomy may be recommended for various reasons, such as treating thyroid nodules, goiter, hyperthyroidism (overactive thyroid), or thyroid cancer. Potential risks and complications of the procedure include bleeding, infection, damage to nearby structures like the parathyroid glands and recurrent laryngeal nerve, and hypoparathyroidism or hypothyroidism due to removal of or damage to the parathyroid glands or thyroid gland, respectively. Close postoperative monitoring and management are essential to minimize these risks and ensure optimal patient outcomes.

DiGeorge syndrome is a genetic disorder caused by the deletion of a small piece of chromosome 22. It is also known as 22q11.2 deletion syndrome. The symptoms and severity can vary widely among affected individuals, but often include birth defects such as congenital heart disease, poor immune system function, and palatal abnormalities. Characteristic facial features, learning disabilities, and behavioral problems are also common. Some people with DiGeorge syndrome may have mild symptoms while others may be more severely affected. The condition is typically diagnosed through genetic testing. Treatment is focused on managing the specific symptoms and may include surgery, medications, and therapy.

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.

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.

Methyclothiazide is a diuretic drug, which is a type of medication that helps the body get rid of excess salt and water by increasing urine production. It is a synthetic derivative of chlorothiazide, another thiazide diuretic. Methyclothiazide works by inhibiting the reabsorption of sodium and chloride ions in the distal convoluted tubule of the nephron in the kidney, which promotes water excretion.

Methyclothiazide is primarily used to treat hypertension (high blood pressure) and edema (swelling) associated with heart failure, liver cirrhosis, or kidney disease. It may also be used for other conditions such as diabetes insipidus and renal tubular acidosis.

Like all medications, methyclothiazide can have side effects, including electrolyte imbalances, dehydration, dizziness, headache, muscle cramps, and gastrointestinal disturbances. It is essential to take this medication as directed by a healthcare provider and to report any unusual symptoms or concerns promptly.

Polyendocrinopathies, autoimmune refers to a group of disorders that involve malfunction of multiple endocrine glands, caused by the immune system mistakenly attacking and damaging these glands. The endocrine glands are responsible for producing hormones that regulate various functions in the body.

There are several types of autoimmune polyendocrinopathies, including:

1. Autoimmune Polyendocrine Syndrome Type 1 (APS-1): Also known as Autoimmune Polyglandular Syndrome Type 1 or APECED, this is a rare inherited disorder that typically affects multiple endocrine glands and other organs. It is caused by mutations in the autoimmune regulator (AIRE) gene.
2. Autoimmune Polyendocrine Syndrome Type 2 (APS-2): Also known as Schmidt's syndrome, this disorder typically involves the adrenal glands, thyroid gland, and/or insulin-producing cells in the pancreas. It is more common than APS-1 and often affects middle-aged women.
3. Autoimmune Polyendocrine Syndrome Type 3 (APS-3): This disorder involves the presence of autoimmune Addison's disease, with or without other autoimmune disorders such as thyroid disease, type 1 diabetes, or vitiligo.
4. Autoimmune Polyendocrine Syndrome Type 4 (APS-4): This is a catch-all category for individuals who have multiple autoimmune endocrine disorders that do not fit into the other types of APS.

Symptoms of autoimmune polyendocrinopathies can vary widely depending on which glands are affected and the severity of the damage. Treatment typically involves replacing the hormones that are no longer being produced in sufficient quantities, as well as managing any underlying immune system dysfunction.

Phosphorus is an essential mineral that is required by every cell in the body for normal functioning. It is a key component of several important biomolecules, including adenosine triphosphate (ATP), which is the primary source of energy for cells, and deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), which are the genetic materials in cells.

Phosphorus is also a major constituent of bones and teeth, where it combines with calcium to provide strength and structure. In addition, phosphorus plays a critical role in various metabolic processes, including energy production, nerve impulse transmission, and pH regulation.

The medical definition of phosphorus refers to the chemical element with the atomic number 15 and the symbol P. It is a highly reactive non-metal that exists in several forms, including white phosphorus, red phosphorus, and black phosphorus. In the body, phosphorus is primarily found in the form of organic compounds, such as phospholipids, phosphoproteins, and nucleic acids.

Abnormal levels of phosphorus in the body can lead to various health problems. For example, high levels of phosphorus (hyperphosphatemia) can occur in patients with kidney disease or those who consume large amounts of phosphorus-rich foods, and can contribute to the development of calcification of soft tissues and cardiovascular disease. On the other hand, low levels of phosphorus (hypophosphatemia) can occur in patients with malnutrition, vitamin D deficiency, or alcoholism, and can lead to muscle weakness, bone pain, and an increased risk of infection.

Human chromosome pair 22 consists of two rod-shaped structures present in the nucleus of each cell in the human body. Each chromosome is made up of DNA tightly coiled around histone proteins, forming a complex structure called a chromatin.

Chromosome pair 22 is one of the 22 autosomal pairs of human chromosomes, meaning they are not sex chromosomes (X or Y). Chromosome 22 is the second smallest human chromosome, with each arm of the chromosome designated as p and q. The short arm is labeled "p," and the long arm is labeled "q."

Chromosome 22 contains several genes that are associated with various genetic disorders, including DiGeorge syndrome, velocardiofacial syndrome, and cat-eye syndrome, which result from deletions or duplications of specific regions on the chromosome. Additionally, chromosome 22 is the location of the NRXN1 gene, which has been associated with an increased risk for autism spectrum disorder (ASD) and schizophrenia when deleted or disrupted.

Understanding the genetic makeup of human chromosome pair 22 can provide valuable insights into human genetics, evolution, and disease susceptibility, as well as inform medical diagnoses, treatments, and research.

Athetosis is a medical term that describes a type of involuntary muscle movement. It is characterized by slow, writhing, and continuous movements that can affect the hands, feet, arms, or legs. These movements are not rhythmic and can be interrupted by other voluntary movements. Athetosis is often seen in individuals with certain neurological conditions, such as cerebral palsy or brain injury. It can also be a side effect of some medications. The exact cause of athetosis is not fully understood, but it is believed to result from damage to the basal ganglia, a part of the brain that helps regulate movement. Treatment for athetosis may include physical therapy, medication, or surgery, depending on the underlying cause and severity of the symptoms.

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.

Vitamin D is a fat-soluble secosteroid that is crucial for the regulation of calcium and phosphate levels in the body, which are essential for maintaining healthy bones and teeth. It can be synthesized by the human body when skin is exposed to ultraviolet-B (UVB) rays from sunlight, or it can be obtained through dietary sources such as fatty fish, fortified dairy products, and supplements. There are two major forms of vitamin D: vitamin D2 (ergocalciferol), which is found in some plants and fungi, and vitamin D3 (cholecalciferol), which is produced in the skin or obtained from animal-derived foods. Both forms need to undergo two hydroxylations in the body to become biologically active as calcitriol (1,25-dihydroxyvitamin D3), the hormonally active form of vitamin D. This activated form exerts its effects by binding to the vitamin D receptor (VDR) found in various tissues, including the small intestine, bone, kidney, and immune cells, thereby influencing numerous physiological processes such as calcium homeostasis, bone metabolism, cell growth, and immune function.

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.

Calcium is an essential mineral that is vital for various physiological processes in the human body. The medical definition of calcium is as follows:

Calcium (Ca2+) is a crucial cation and the most abundant mineral in the human body, with approximately 99% of it found in bones and teeth. It plays a vital role in maintaining structural integrity, nerve impulse transmission, muscle contraction, hormonal secretion, blood coagulation, and enzyme activation.

Calcium homeostasis is tightly regulated through the interplay of several hormones, including parathyroid hormone (PTH), calcitonin, and vitamin D. Dietary calcium intake, absorption, and excretion are also critical factors in maintaining optimal calcium levels in the body.

Hypocalcemia refers to low serum calcium levels, while hypercalcemia indicates high serum calcium levels. Both conditions can have detrimental effects on various organ systems and require medical intervention to correct.

Hydroxycholecalciferols are metabolites of vitamin D that are formed in the liver and kidneys. They are important for maintaining calcium homeostasis in the body by promoting the absorption of calcium from the gut and reabsorption of calcium from the kidneys.

The two main forms of hydroxycholecalciferols are 25-hydroxyvitamin D (25(OH)D) and 1,25-dihydroxyvitamin D (1,25(OH)2D). 25-hydroxyvitamin D is the major circulating form of vitamin D in the body and is used as a clinical measure of vitamin D status. It is converted to 1,25-dihydroxyvitamin D in the kidneys by the enzyme 1α-hydroxylase, which is activated in response to low serum calcium or high phosphate levels.

1,25-dihydroxyvitamin D is the biologically active form of vitamin D and plays a critical role in regulating calcium homeostasis by increasing intestinal calcium absorption and promoting bone health. Deficiency in hydroxycholecalciferols can lead to rickets in children and osteomalacia or osteoporosis in adults, characterized by weakened bones and increased risk of fractures.

Dihydrotachysterol is a synthetic form of vitamin D that is used as a medication to treat hypocalcemia (low levels of calcium in the blood) in people with certain medical conditions, such as hypoparathyroidism and vitamin D deficiency. It works by increasing the absorption of calcium from the gut and promoting the release of calcium from bones into the bloodstream.

Dihydrotachysterol is available in tablet form and is typically taken once or twice a day, with the dosage adjusted based on the individual's response to treatment and serum calcium levels. Common side effects of dihydrotachysterol include hypercalcemia (high levels of calcium in the blood), nausea, vomiting, and constipation. It is important to monitor serum calcium levels regularly while taking this medication to prevent toxicity.

Calcitriol is the active form of vitamin D, also known as 1,25-dihydroxyvitamin D. It is a steroid hormone that plays a crucial role in regulating calcium and phosphate levels in the body to maintain healthy bones. Calcitriol is produced in the kidneys from its precursor, calcidiol (25-hydroxyvitamin D), which is derived from dietary sources or synthesized in the skin upon exposure to sunlight.

Calcitriol promotes calcium absorption in the intestines, helps regulate calcium and phosphate levels in the kidneys, and stimulates bone cells (osteoblasts) to form new bone tissue while inhibiting the activity of osteoclasts, which resorb bone. This hormone is essential for normal bone mineralization and growth, as well as for preventing hypocalcemia (low calcium levels).

In addition to its role in bone health, calcitriol has various other physiological functions, including modulating immune responses, cell proliferation, differentiation, and apoptosis. Calcitriol deficiency or resistance can lead to conditions such as rickets in children and osteomalacia or osteoporosis in adults.

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.

Vocal cord paralysis is a medical condition characterized by the inability of one or both vocal cords to move or function properly due to nerve damage or disruption. The vocal cords are two bands of muscle located in the larynx (voice box) that vibrate to produce sound during speech, singing, and breathing. When the nerves that control the vocal cord movements are damaged or not functioning correctly, the vocal cords may become paralyzed or weakened, leading to voice changes, breathing difficulties, and other symptoms.

The causes of vocal cord paralysis can vary, including neurological disorders, trauma, tumors, surgery, or infections. The diagnosis typically involves a physical examination, including a laryngoscopy, to assess the movement and function of the vocal cords. Treatment options may include voice therapy, surgical procedures, or other interventions to improve voice quality and breathing functions.

Substernal goiter refers to an enlarged thyroid gland that extends below the sternum or breastbone. It is also known as a retrosternal goiter. This condition can cause compression of surrounding structures such as the trachea and esophagus, leading to symptoms like difficulty swallowing, shortness of breath, and cough. Substernal goiters may be asymptomatic or may require treatment, including surgery, to alleviate symptoms and prevent complications.

Hormone Replacement Therapy (HRT) is a medical treatment that involves the use of hormones to replace or supplement those that the body is no longer producing or no longer producing in sufficient quantities. It is most commonly used to help manage symptoms associated with menopause and conditions related to hormonal imbalances.

In women, HRT typically involves the use of estrogen and/or progesterone to alleviate hot flashes, night sweats, vaginal dryness, and mood changes that can occur during menopause. In some cases, testosterone may also be prescribed to help improve energy levels, sex drive, and overall sense of well-being.

In men, HRT is often used to treat low testosterone levels (hypogonadism) and related symptoms such as fatigue, decreased muscle mass, and reduced sex drive.

It's important to note that while HRT can be effective in managing certain symptoms, it also carries potential risks, including an increased risk of blood clots, stroke, breast cancer (in women), and cardiovascular disease. Therefore, the decision to undergo HRT should be made carefully and discussed thoroughly with a healthcare provider.

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.

Chorea is a medical term that describes an involuntary movement disorder characterized by brief, irregular, and abrupt jerky movements. These movements often occur randomly and can affect any part of the body. Chorea can also cause difficulty with coordination and balance, and can sometimes be accompanied by muscle weakness or rigidity.

The term "chorea" comes from the Greek word "χορεία" (khoréia), which means "dance," reflecting the graceful, dance-like movements that are characteristic of this condition. Chorea can occur as a symptom of various underlying medical conditions, including neurological disorders such as Huntington's disease, Sydenham's chorea, and cerebral palsy, as well as metabolic disorders, infections, and certain medications.

Treatment for chorea depends on the underlying cause of the condition and may include medications to help control the involuntary movements, physical therapy to improve coordination and balance, and lifestyle modifications to reduce the risk of injury from falls or other accidents. In some cases, surgery may be recommended as a last resort for severe or refractory chorea.

Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks and in the shells of many marine animals. As a mineral, it is known as calcite or aragonite.

In the medical field, calcium carbonate is often used as a dietary supplement to prevent or treat calcium deficiency. It is also commonly used as an antacid to neutralize stomach acid and relieve symptoms of heartburn, acid reflux, and indigestion.

Calcium carbonate works by reacting with hydrochloric acid in the stomach to form water, carbon dioxide, and calcium chloride. This reaction helps to raise the pH level in the stomach and neutralize excess acid.

It is important to note that excessive use of calcium carbonate can lead to hypercalcemia, a condition characterized by high levels of calcium in the blood, which can cause symptoms such as nausea, vomiting, constipation, confusion, and muscle weakness. Therefore, it is recommended to consult with a healthcare provider before starting any new supplement regimen.

Calcium gluconate is a medical compound that is used primarily as a medication to treat conditions related to low calcium levels in the body (hypocalcemia) or to prevent calcium deficiency. It is also used as an antidote for treating poisoning from certain chemicals, such as beta-blockers and fluoride.

Calcium gluconate is a form of calcium salt, which is combined with gluconic acid, a natural organic acid found in various fruits and honey. This compound has a high concentration of calcium, making it an effective supplement for increasing calcium levels in the body.

In medical settings, calcium gluconate can be administered orally as a tablet or liquid solution, or it can be given intravenously (directly into a vein) by a healthcare professional. The intravenous route is typically used in emergency situations to quickly raise calcium levels and treat symptoms of hypocalcemia, such as muscle cramps, spasms, or seizures.

It's important to note that while calcium gluconate can be beneficial for treating low calcium levels, it should only be used under the guidance of a healthcare provider, as improper use or overdose can lead to serious side effects, including kidney damage and heart problems.
