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 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.
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 nutritional condition produced by a deficiency of magnesium in the diet, characterized by anorexia, nausea, vomiting, lethargy, and weakness. Symptoms are paresthesias, muscle cramps, irritability, decreased attention span, and mental confusion, possibly requiring months to appear. Deficiency of body magnesium can exist even when serum values are normal. In addition, magnesium deficiency may be organ-selective, since certain tissues become deficient before others. (Harrison's Principles of Internal Medicine, 12th ed, p1936)
The calcium salt of gluconic acid. The compound has a variety of uses, including its use as a calcium replenisher in hypocalcemic states.
Surgical removal of the thyroid gland. (Dorland, 28th ed)
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 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.
Abnormally high level of calcium in the blood.
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.
Excision of one or more of the parathyroid glands.
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.
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.

Disorders caused by interruption of BONE MINERALIZATION manifesting as OSTEOMALACIA in adults and characteristic deformities in infancy and childhood due to disturbances in normal BONE FORMATION. The mineralization process may be interrupted by disruption of VITAMIN D; PHOSPHORUS; or CALCIUM homeostasis, resulting from dietary deficiencies, or acquired, or inherited metabolic, or hormonal disturbances.
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 metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
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.
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.
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 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.

Disorders in the processing of calcium in the body: its absorption, transport, storage, and utilization.
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.
A disorder characterized by muscle twitches, cramps, and carpopedal spasm, and when severe, laryngospasm and seizures. This condition is associated with unstable depolarization of axonal membranes, primarily in the peripheral nervous system. Tetany usually results from HYPOCALCEMIA or reduced serum levels of MAGNESIUM that may be associated with HYPERVENTILATION; HYPOPARATHYROIDISM; RICKETS; UREMIA; or other conditions. (From Adams et al., Principles of Neurology, 6th ed, p1490)
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
A peptide hormone that lowers calcium concentration in the blood. In humans, it is released by thyroid cells and acts to decrease the formation and absorptive activity of osteoclasts. Its role in regulating plasma calcium is much greater in children and in certain diseases than in normal adults.
Pathological processes involving the THYROID GLAND.
Calcium compounds used as food supplements or in food to supply the body with calcium. Dietary calcium is needed during growth for bone development and for maintenance of skeletal integrity later in life to prevent osteoporosis.
A common form of hyperthyroidism with a diffuse hyperplastic GOITER. It is an autoimmune disorder that produces antibodies against the THYROID STIMULATING HORMONE RECEPTOR. These autoantibodies activate the TSH receptor, thereby stimulating the THYROID GLAND and hypersecretion of THYROID HORMONES. These autoantibodies can also affect the eyes (GRAVES OPHTHALMOPATHY) and the skin (Graves dermopathy).
Organic compounds which contain P-C-P bonds, where P stands for phosphonates or phosphonic acids. These compounds affect calcium metabolism. They inhibit ectopic calcification and slow down bone resorption and bone turnover. Technetium complexes of diphosphonates have been used successfully as bone scanning agents.
A condition of an abnormally low level of PHOSPHATES in the blood.
A small colorless crystal used as an anticonvulsant, a cathartic, and an electrolyte replenisher in the treatment of pre-eclampsia and eclampsia. It causes direct inhibition of action potentials in myometrial muscle cells. Excitation and contraction are uncoupled, which decreases the frequency and force of contractions. (From AMA Drug Evaluations Annual, 1992, p1083)
Decalcification of bone or abnormal bone development due to chronic KIDNEY DISEASES, in which 1,25-DIHYDROXYVITAMIN D3 synthesis by the kidneys is impaired, leading to reduced negative feedback on PARATHYROID HORMONE. The resulting SECONDARY HYPERPARATHYROIDISM eventually leads to bone disorders.
Disorder caused by an interruption of the mineralization of organic bone matrix leading to bone softening, bone pain, and weakness. It is the adult form of rickets resulting from disruption of VITAMIN D; PHOSPHORUS; or CALCIUM homeostasis.

Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.
A subspecialty of internal medicine concerned with the study of neoplasms.
New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.

Microdeletion 22q11 and oesophageal atresia. (1/502)

Oesophageal atresia (OA) is a congenital defect associated with additional malformations in 30-70% of the cases. In particular, OA is a component of the VACTERL association. Since some major features of the VACTERL association, including conotruncal heart defect, radial aplasia, and anal atresia, have been found in patients with microdeletion 22q11.2 (del(22q11.2)), we have screened for del(22q11.2) by fluorescent in situ hybridisation (FISH) in 15 syndromic patients with OA. Del(22q11.2) was detected in one of them, presenting with OA, tetralogy of Fallot, anal atresia, neonatal hypocalcaemia, and subtle facial anomalies resembling those of velocardiofacial syndrome. The occurrence of del(22q11.2) in our series of patients with OA is low (1/15), but this chromosomal anomaly should be included among causative factors of malformation complexes with OA. In addition, clinical variability of del(22q11.2) syndrome is further corroborated with inclusion of OA in the list of the findings associated with the deletion.  (+info)

Recurrent hyperparathyroidism. (2/502)

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)

Effect of rate of calcium reduction and a hypocalcemic clamp on parathyroid hormone secretion: a study in dogs. (3/502)

BACKGROUND: The parathyroid hormone (PTH) calcium curve is used to evaluate parathyroid function in clinical studies. However, unanswered questions remain about whether PTH secretion is affected by the rate of calcium reduction and how the maximal PTH response to hypocalcemia is best determined. We performed studies in normal dogs to determine whether (a) the rate of calcium reduction affected the PTH response to hypocalcemia and (b) the reduction in PTH values during a hypocalcemic clamp from the peak PTH value observed during the nadir of hypocalcemia was due to a depletion of stored PTH. METHODS: Fast (30 min) and slow (120 min) ethylenediamine-tetraacetic acid (EDTA) infusions were used to induce similar reductions in ionized calcium. In the fast EDTA infusion group, serum calcium was maintained at the hypocalcemic 30-minute value for an additional 90 minutes (hypocalcemic clamp). To determine whether the reduction in PTH values during the hypocalcemic clamp represented depletion of PTH stores, three subgroups were studied. Serum calcium was rapidly reduced from established hypocalcemic levels in the fast-infusion group at 30 and 60 minutes (after 30 min of a hypocalcemic clamp) and in the slow-infusion group at 120 minutes. RESULTS: At the end of the fast and slow EDTA infusions, serum ionized calcium values were not different (0.84 +/- 0.02 vs. 0.82 +/- 0.03 mM), but PTH values were greater in the fast-infusion group (246 +/- 19 vs. 194 +/- 13 pg/ml, P < 0.05). During the hypocalcemic clamp, PTH rapidly decreased (P < 0.05) to value of approximately 60% of the peak PTH value obtained at 30 minutes. A rapid reduction in serum calcium from established hypocalcemic levels at 30 minutes did not stimulate PTH further, but also PTH values did not decrease as they did when a hypocalcemic clamp was started at 30 minutes. At 60 minutes, the reduction in serum calcium increased (P < 0.05) PTH to peak values similar to those before the hypocalcemic clamp. The reduction in serum calcium at 120 minutes in the slow EDTA infusion group increased PTH values from 224 +/- 11 to 302 +/- 30 pg/ml (P < 0.05). CONCLUSIONS: These results suggest that (a) the reduction in PTH values during the hypocalcemic clamp may not represent a depletion of PTH stores. (b) The use of PTH values from the hypocalcemic clamp as the maximal PTH may underestimate the maximal secretory capacity of the parathyroid glands and also would change the analysis of the PTH-calcium curve, and (c) the PTH response to similar reductions in serum calcium may be less for slow than fast reductions in serum calcium.  (+info)

Evidence for the promotion of bone mineralization by 1alpha,25-dihydroxycholecalciferol in the rat unrelated to the correction of deficiencies in serum calcium and phosphorus. (4/502)

Concurrent administration of 1alpha,25-dihydroxycholecalciferol [1alpha,25-(OH)2-CC] to intact and thyroparathyroidectomized rats treated with ethane-1-hydroxy-1,1-diphosphonate (EHDP) prevented or reversed the EHDP-induced inhibition of bone mineralization as measured by changes in epiphyseal plate width and ash content of bone. An analog, 1alpha-droxycholecalciferol, was also effective. Recovery of bone after EHDP treatment was also significantly improved by administration of 1alpha,25-(OH)2-CC as evidenced by enhanced uptake of 45Ca by epiphyseal plates and decreased plate widths. Cholecalciferol (CC), ergocalciferol, dihydrotachysterol2, 5,6-trans-CC, 25-OH-CC, 5,6-Trans-25-OH-CC, and 1alpha24R,25-(OH)3-CC also blocked EHDP-induced epiphyseal plate widening, but required high, pharmacological dose levels. 24R,25- (OH)2-CC was inactive at doses up to 10 microgram/day. Since EHDP-treated rats are not deficient in calcium or phosphate, these data suggest that 1alpha,25-dihydroxycholecalciferol promoted bone mineralization independently of effects upon the intestinal absorption of calcium and phosphate.  (+info)

Calcitonin is a major regulator for the expression of renal 25-hydroxyvitamin D3-1alpha-hydroxylase gene in normocalcemic rats. (5/502)

Regulation of vitamin D metabolism has long been examined by using vitamin D-deficient hypocalcemic animals. We previously reported that, in a rat model of chronic hyperparathyroidism, expression of 25-hydroxyvitamin D3-1alpha-hydroxylase (CYP27B1) mRNA was markedly increased in renal proximal convoluted tubules. It is believed that the major regulator for the expression of renal CYP27B1 is parathyroid hormone (PTH). However, in the normocalcemic state, the mechanism to regulate the renal CYP27B1 gene could be different, since plasma levels of PTH are very low. In the present study, the effect of PTH and calcitonin (CT) on the expression of renal CYP27B1 mRNA was investigated in normocalcemic sham-operated rats and normocalcemic thyroparathyroidectomized (TPTX) rats generated by either PTH or CaCl2 infusion. A single injection of CT dose-dependently decreased the expression of vitamin D receptor mRNA in the kidney of normocalcemic sham-TPTX rats. Concomitantly, CT greatly increased the expression of CYP27B1 mRNA in the kidney of normocalcemic sham-TPTX rats. CT also increased the expression of CYP27B1 mRNA in the kidney of normocalcemic TPTX rats. Conversion of serum [3H]1alpha,25(OH)2D3 from 25-hydroxy[3H]vitamin D3 in vivo was also greatly increased by the injection of CT into sham-TPTX rats and normocalcemic TPTX rats, but not into hypocalcemic TPTX rats. In contrast, administration of PTH did not induce the expression of CYP27B1 mRNA in the kidney of vitamin D-replete sham-TPTX rats and hypocalcemic TPTX rats. PTH increased the expression of renal CYP27B1 mRNA only in vitamin D-deficient hypocalcemic TPTX rats. These results suggest that CT plays an important role in the maintenance of serum 1alpha,25(OH)2D3 under normocalcemic physiological conditions, at least in rats.  (+info)

Calcimimetic compound NPS R-568 stimulates calcitonin secretion but selectively targets parathyroid gland Ca(2+) receptor in rats. (6/502)

N-(3-[2-Chlorophenyl]propyl)-(R)-alpha-methyl-3-methoxybenzylamine (NPS R-568) is an orally active compound that activates Ca(2+) receptors on parathyroid cells and rapidly suppresses plasma levels of parathyroid hormone (PTH) and Ca(2+) (ED(50), 1 and 10 mg/kg, respectively). We now show that increased calcitonin secretion contributes to NPS R-568-induced hypocalcemia. In parathyroidectomized thyroid-intact rats in which normocalcemia was restored by PTH infusion, NPS R-568 rapidly reduced plasma Ca(2+) levels, indicating that decreased PTH secretion was not solely responsible for the hypocalcemia seen in normal animals. NPS R-568 decreased plasma Ca(2+) levels in thyroidectomized parathyroid-intact rats, but the rate of onset of hypocalcemia was slower than in controls. In contrast, NPS R-568 had no effect on plasma Ca(2+) levels in PTH-infused, thyroparathyroidectomized rats, providing evidence that increased calcitonin secretion caused the hypocalcemia in PTH-infused parathyroidectomized rats. NPS R-568 rapidly increased plasma calcitonin levels to a peak at 10 to 20 min after oral dosing (ED(50) 40 mg/kg). NPS R-568 did not affect the rate of disappearance of (45)Ca from blood, indicating that hypocalcemia resulted from decreased influx of Ca(2+) into the circulation and not from increased efflux. This suggests that NPS R-568-induced hypocalcemia resulted solely from reduced efflux of Ca(2+) from bone after increased calcitonin and reduced PTH secretion. Thus, NPS R-568 causes hypocalcemia by activating Ca(2+) receptors on C cells and parathyroid cells; however, NPS R-568 is about 40 times more potent in reducing PTH levels than in increasing calcitonin levels.  (+info)

Calciotrophic hormones during experimental hypocalcaemia and hypercalcaemia in spontaneously diabetic rats. (7/502)

1,25-Dihydroxyvitamin D(3) (1,25(OH)(2)D(3)) concentrations have been found to be decreased in diabetic humans and rats. To investigate further the regulation of plasma Ca in diabetes, first we measured Ca(2+), P, Mg, parathyroid hormone(1-34) (PTH), and total and free 1,25(OH)(2)D(3) in male spontaneously diabetic rats 7 and 28 days after the onset of glycosuria. Secondly, we studied changes in the levels of PTH and 1,25(OH)(2)D(3) in response to hypocalcaemia induced by an i.v. infusion of EGTA (2.5%, wt/vol.) for 24 h, and changes in the levels of 1,25(OH)(2)D(3) in response to an i.v. infusion of rat PTH (10 microgram over 24 h) without or with concomitant EGTA infusion (producing hypercalcaemia or normo/hypocalcaemia respectively), in diabetic and control rats. Ca(2+), P, Mg and PTH concentrations remained within the control ranges after 7 and 28 days of glycosuria; 1,25(OH)(2)D(3) concentrations were decreased after 7, but not after 28, days of glycosuria. PTH concentrations showed a similar rise during EGTA-induced hypocalcaemia in control and diabetic rats compared with saline-infused rats, whereas 1,25(OH)(2)D(3) concentrations were unchanged in both groups. Total and free 1,25(OH)(2)D(3) levels were comparably (about 3-fold) increased during PTH, but not during combined PTH and EGTA infusion in control and diabetic rats. Total 1, 25(OH)(2)D(3) concentrations were lower in the diabetic groups infused with saline or PTH than in their respective controls, and there was a similar trend in the PTH+EGTA-infused group; free 1, 25(OH)(2)D(3) levels, however, were normal or increased in the diabetic groups, confirming our previous data. The novel finding of this study is that, despite severe insulin deficiency and altered 1, 25(OH)(2)D(3) levels, the in vivo response of PTH levels to hypocalcaemia and the in vivo response of 1,25(OH)(2)D(3) levels to PTH in diabetic rats are comparable with those found in nondiabetic rats.  (+info)

Hormonal control of calcium homeostasis. (8/502)

Calcium homeostasis in the extracellular fluid is tightly controlled and defended physiologically. Hypercalcemia always represents considerable underlying pathology and occurs when the hormonal control of calcium homeostasis is overwhelmed. The major hormones that are responsible for normal calcium homeostasis are parathyroid hormone and 1,25-dihydroxyvitamin D; these hormones control extracellular fluid calcium on a chronic basis. Over- or underproduction of these hormones or the tumor peptide, parathyroid hormone-related peptide, are the major causes of aberrant extracellular fluid calcium concentrations. These hormonal defense mechanisms are reviewed here.  (+info)

The medical literature contains few reports of hypocalcemia accompanying osteoblastic osseous metastases, and the combination of hypocalcemia and hypophosphatemia accompanying such lesions has not been described previously. Five patients displaying hypocalcemia in association with osteoblastic metastases form the substance of this report. Two of them, whose primary lesions were carcinoma of the prostate gland, also had marked hypophosphatemia, and, in both, estrogen therapy appeared to induce the hypocalcemia and hypophosphatemia. A third patient having osteoblastic metastases from prostate carcinoma also developed hypocalcemia only after estrogenic therapy, but the serum phosphate remained normal. The other two patients, who were never given ...
Hypomagnesemia with secondary hypocalcemia (HSH) is an autosomal recessive genetic disorder affecting intestinal magnesium absorption. Decreased intestinal magnesium reabsorption and the resulting decrease in serum magnesium levels is believed to cause lowered parathyroid hormone (PTH) output by the parathyroid gland. This results in decreased PTH and decreased serum calcium levels (hypocalcemia). This manifests in convulsions and spasms in early infancy which, if left untreated, can lead to mental retardation or death. HSH is caused by mutations in the TRPM6 gene. Diagnosis typically occurs during the first 6 months of life due to characteristic neurological symptoms. These symptoms include muscle spasms, tetany, and seizures. Laboratory testing indicates hypomagnesemia (decreased serum magnesium levels), hypocalcemia (decreased serum calcium levels), and little to no measurable parathyroid hormone levels. Diagnosis is confirmed with these symptoms and can be further solidified with genetic ...

Bisphosphonates are generally considered as safe drugs but, can be associated with laboratory abnormalities, particularly, elevated serum creatinine levels and hypocalcemia.[1] Sporadic episodes of acute and subacute renal failure have been reported, whereas hypocalcemia has not yet been the subject of detailed research.. Theoretically, intravenous bisphosphonate guarantees 100% absorption without gastrointestinal adverse effects thereby advantageous over oral bisphosphonate. Particularly, zoledronate has gained popularity as an osteoporosis treatment since its injection time (15 minutes) is shorter than that of other intravenous bisphosphonates and the injection is performed only once a year.. Maximum plasma concentrations of zoledronic acid are reached, as expected, at the end of the IV infusion. Blood levels then rapidly decline to less than 10% at four hours and to less than 1% at 24 hours after infusion. Half-life is known to be as long as 146 hours.[2] About 61% of the administered dose is ...
Hungry bones syndrome is a disorder characterized by significant and persistent hypocalcemia, even though serum parathormone levels may be normal or even augmented. This disorder occurs following an increase of the bone formation to bone resorption ratio, a state which leads to the abundant amount of calcium than that required by the organism.… Hungry Bones Syndrome (Hungry Bone Syndrome): Read more about Symptoms, Diagnosis, Treatment, Complications, Causes and Prognosis.

Proc. Aust. Soc. Anim. Prod. Vol. 19 ACID-BASE BALANCE AND SUSCEPTIBILITY OF EWES TO HYPOCALCAEMIA I. McL. GRANT A. M. BINGHAM, and I. W. CAPLE University of Melbourne, Dept of Veterinary Science, Werribee, 3030. SUMMARY The effect of acid-base balance on the susceptibility of ewes to hypocalcaemia was determined in groups of ewes fed 3 diets where the fixed cation-anion balance [Na + K - Cl] was -4.1, 29.1 and 82.3 meq/lOO g DM, respectively. Ewes fed the diet with a fixed cation excess (82.3 meq/lOO g DM) had higher urine pH and lower urine Ca concentrations. They also had lower blood ionised Ca concentrations after an overnight fast, and tended to develop hypocalcaemia more rapidly during EDTA infusion than ewes fed a diet with a fixed anion excess (-4.1 meq/lOO g DM). It was concluded that dietary fixed cation-anion balance may be a factor which predisposes pregnant ewes to hypocalcaemia. Keywords: hypocalcaemia, calcium, acid-base, pH. INTRODUCTION Hypocalcaemia in pregnant ewes is a common ...
The causes of early hypocalcemia are unknown, while late hypocalcemia has a number of known causes, related primarily to calcium and phosphorus levels in the body as well as parathyroid hormone function.. Hypocalcemia is more common in premature and low birthweight babies, because their parathyroid glands are less mature. It can also occur in babies who have a difficult birth and in babies of diabetic mothers.. ...
Heterotrimeric G proteins play critical roles in transducing extracellular signals generated by 7-transmembrane domain receptors. Somatic gain-of-function mutations in G protein α subunits are associated with a variety of diseases. Recently, we identified gain-of-function mutations in Gα11 in patients with autosomal-dominant hypocalcemia type 2 (ADH2), an inherited disorder of hypocalcemia, low parathyroid hormone (PTH), and hyperphosphatemia. We have generated knockin mice harboring the point mutation GNA11 c.C178T (p.Arg60Cys) identified in ADH2 patients. The mutant mice faithfully replicated human ADH2. They also exhibited low bone mineral density and increased skin pigmentation. Treatment with NPS 2143, a negative allosteric modulator of the calcium-sensing receptor (CASR), increased PTH and calcium concentrations in WT and mutant mice, suggesting that the gain-of-function effect of GNA11(R6OC) is partly dependent on coupling to the CASR. Treatment with the Gα11/q-specific inhibitor ...
The intravenous Na2EDTA infusion technique allows effective specific chelation of circulating Ca2+ leading to a progressive hypocalcaemia. Methods previously used were not described in detail and results obtained by monitoring total and free ionic calcium were not comparable due to differences in sampling and analysis. This paper describes a standardized EDTA infusion technique that allowed comparison of the response of calcium, phosphorus and magnesium between 2 groups of experimental cows. The concentration of the Na2EDTA solution was 0.134 mol/l and the flow rate was standardized at 1.2 ml/kg per hour. Involuntary recumbency occurred when ionised calcium dropped to 0.39 - 0.52 mmol/l due to chelation. An initial fast drop of ionized calcium was observed during the first 20 min of infusion followed by a fluctuation leading to a further drop until recumbency. Pre-infusion [Ca2+] between tests does not correlate with the amount of EDTA required to induce involuntary recumbence. Total calcium

Doctors do not know what causes early hypocalcemia.. Late hypocalcemia is rare and has a number of known causes. Late hypocalcemia is usually caused by drinking cows milk or formula that has too much phosphate. It may be connected to calcium and phosphorus levels in the body. It can also be caused by a problem with parathyroid hormone. This hormone is made by the parathyroid glands in the neck. It helps keep the amount of calcium and phosphorus at a normal level in the blood. Low parathyroid hormone levels can cause too little calcium in the blood. A number of conditions, such as DiGeorge syndrome (22q11.2 deletion syndrome), may cause low parathyroid hormone levels. ...
Prolia is contraindicated in patients with hypocalcemia. Preexisting hypocalcemia must be corrected prior to initiating Prolia. Prolia is contraindicated in women who are pregnant and may cause fetal harm. Prolia is contraindicated in patients with a history of systemic hypersensitivity to any component of the product. Reactions have included anaphylaxis, facial swelling and urticaria. Prolia® contains the same active ingredient (denosumab) found in XGEVA®. Patients receiving Prolia® should not receive XGEVA®.. Clinically significant hypersensitivity including anaphylaxis has been reported with Prolia®. Symptoms have included hypotension, dyspnea, throat tightness, facial and upper airway edema, pruritus, and urticaria. If an anaphylactic or other clinically significant allergic reaction occurs, initiate appropriate therapy and discontinue further use of Prolia®. Hypocalcemia may worsen with the use of Prolia®, especially in patients with severe renal impairment. In patients predisposed ...
Intravenous injection of commercial parathyroid extract into fasted dogs resulted in a transient hypocalcemia. The plasma calcium fell 0.40 to 0.65 mg/100 ml within 20 minutes and then rose in the characteristic response to the parathyroid hormone. The hypocalcemic response was similar to that ascribed to the recently reported hormone calcitonin, and the data suggest that the extract may contain both. ...
Ionised hypocalcaemia has been observed post-cardiac arrest in previous studies. Investigators in Utah induced VF in a swine model and resuscitated them back to spontaneous circulation1. Ionised hypocalcaemia was associated with hypotension and impaired LV function, and its treatment with a calcium infusion resulted in improved mean arterial pressure and left ventricular stroke work.. Although iv calcium is not recommended as a blind treatment in cardiac arrest, in part due to concerns about exacerbating cellular injury, this study reminds us that the treatment of ionised hypocalcaemia is important, and may be necessary after ROSC.. 1.

As many of you already know, the last several years have been a roller coaster of health concerns for me. I spent the last 8 years trying to find out what was wrong with me. Why it hurt to tears when my husband gave me a playful slap on the behind. I swear it is not aggressive or abusive. Just hear me out. Pain over my whole body. No ambition or energy. Brain fog when I used to be so quick with my whits. No organization. Tons to do but a grand lack of energy to do anything more than daydream about what I wished I was accomplishing. Some days I had some fight in me, and I did as much as I could, but most days, I just felt like there was something wrong with me, and no one could tell me what. Every medical test looks healthy. As a matter of fact, my body is the picture of health for someone my age. Every single test within normal limits. Every image the doctors gush over how perfect my organs look. Great. I am healthy as can be, so why do I hurt so bad? Why cant I get anything done or stay ...

World Health Organization, Geneva. Williams, S. , Lawrence, L. , McDowell, L. , Wilkinson, N. , Ferguson, P. , and Warnick, A. , (1991). J. Anim. Sci. 69, 1232. Chapter 2 Calcium and Phosphorus I. INTRODUCTION Calcium (Ca) and phosphorus (P) are considered together because they constitute the major part of the mineral content of bone. They are very closely related; a deficiency or an excess of one wi11 interfere with the proper utilization of the other. The Ca: P ratio in the bone is slightly greater than 2: 1 and is approximately constant. INTESTINAL EFFECTS Vitamin 0 stimulates active transport of Ca and P across intestinal epithelium. This stimulation does not involve PTH directly but involves the active form of vitamin D. PTH indirectly stimulates intestinal Ca absorption by stimulating production of 1,25-(OHhD under conditions of hypocalcemia. In humans, as the body becomes vitamin 0 insufficient, the efficiency of intestinal Ca absorption decreases from 30 to 50% to no more than 15%. The ...

We report on two patients on chronic hemodialysis, who presented with typical symptoms of hyperkalemia (lower limb paresia and characteristic electrocardiogram [ECG]) for an only mildly increased kalemia (6.1 and 6.2 mEq/L), values that are frequently seen in asymptomatic patients on chronic hemodialysis. Their common denominator was a concomitant hypocalcemia (7.5 et 6.4mg/dL) induced by cinacalcet treatment. Hypocalcemia has very likely precipitated the occurrence of clinical and electrocardiological manifestations of hyperkalemia. This observation is in agreement with previous publications showing that, in other clinical situations than the use of cinacalcet, hypocalcemia potentiates the effect of hyperkalemia on muscle membrane. Nephrologists should be aware of this complication and pay most attention in their patients on chronic dialysis with a calcemia less than 8mg/dL induced by cinacalcet treatment. ...

Hypoparathyroidism is a common cause of hypocalcemia. Calcium is tightly regulated by the parathyroid hormone (PTH). In response to low calcium levels, PTH induces the kidneys to reabsorb calcium, the kidneys to increase production of calcitriol (the active form of vitamin D) thereby increasing intestinal absorption of calcium, and the bones to release calcium. These actions lead to a re-balance in the blood calcium levels. However, in the setting of absent, decreased, or ineffective PTH hormone, the body loses this regulatory function, and hypocalcemia ensues. Hypoparathyroidism is commonly due to surgical destruction of the parathyroid glands via parathyroidectomy or neck dissection for head and neck cancers. Hypoparathyroidism may also be due to autoimmune destruction of the glands.[citation needed]. ...

Hemostasis in thyroid surgery is of utmost importance for a successful surgery and an uneventful postoperative course. Our aim was to evaluate the effectiveness of the FOCUS Harmonic Scalpel in patients undergoing open total thyroidectomy. In this study, 778 patients were randomized into 2 groups based on the surgical technique used: group I comprised the conventional clamp-and-tie technique, group II comprised patients in whom the FOCUS Harmonic Scalpel was used exclusively. The groups were compared in regard to surgical time, complications, and hospital stay. Surgical time was significantly lower in group II compared with group I (79 ± 21.5 min vs.125 ± 30.4, respectively, P | 0.001). Twenty-seven patients (6.94%) in group I experienced symptomatic hypocalcemia requiring calcium and/or vitamin D therapy versus 14 patients (3.6%) in group II, with statistically significant difference (P | 0.05). Mean post-operative hospital stay was significantly lower in group II compared with group I (2.6 ± 0.9 vs
The management should be broken down into the acute and chronic phases of treatment. The acute phase being focused on the rapid reduction of serum phosphorus levels in the short-term, while tackling the long-term treatment should be treating the underlying etiology of hyperphosphatemia.. The acute issue at hand is symptomatic hyperphosphatemia due to its effects on serum calcium, PTH and soft tissue.. This typically occurs if the elevation in phosphorus is very abrupt and may lead to symptomatic hypocalcemia marked by tentany, QTc prolongation, and even seizures. When the calcium-phosphorus product nears 60mg2 per dL2, precipitation of calcium-phosphate salts may occur. Once the product exceeds 70mg2 per dL2, metastatic calcification is likely, and is common to occur in the heart, blood vessels, lungs, kidneys, gastric mucosa and cornea.. The goal of treatment for symptomatic hyperphosphatemia should be aimed at forced diuresis. Normal saline infusion is the initial treatment of choice to ...

The features of this syndrome vary widely, even among members of the same family, and affect many parts of the body. Characteristic signs and symptoms may include birth defects such as congenital heart disease, defects in the palate, most commonly related to neuromuscular problems with closure (velo-pharyngeal insufficiency), learning disabilities, mild differences in facial features, and recurrent infections. Infections are common in children due to problems with the immune systems T-cell mediated response that in some patients is due to an absent or hypoplastic thymus. 22q11.2 deletion syndrome may be first spotted when an affected newborn has heart defects or convulsions from hypocalcemia due to malfunctioning parathyroid glands and low levels of parathyroid hormone (parathormone).

TRPM6 is crucial for human Mg2+ homeostasis as patients carrying TRPM6 mutations develop hypomagnesemia and secondary hypocalcemia (HSH). However, the activation mechanism of TRPM6 has remained unknown. Here we demonstrate that phosphatidylinositol-4,5-bisphophate (PIP2) controls TRPM6 activation and Mg2+ influx. Stimulation of PLC-coupled M1-receptors to deplete PIP2 potently inactivates TRPM6. Translocation of over-expressed 5-phosphatase to cell membrane to specifically hydrolyze PIP2 also completely inhibits TRPM6. Moreover, depolarization-induced-activation of the voltage-sensitive-phosphatase (Ci-VSP) simultaneously depletes PIP2 and inhibits TRPM6. PLC-activation induced PIP2-depletion not only inhibits TRPM6, but also abolishes TRPM6-mediated Mg2+ influx.Furthermore, neutralization of basic residues in the TRP domain leads to nonfunctional or dysfunctional mutants with reduced activity by PIP2, suggesting that they are likely to participate in interactions with PIP2.Our data indicate ...

Hypoparathyroidism (HPTH) is a rare endocrine condition that is unknown by many people because it is so uncommon. Although it only affects a small number of people, its effects on a person are huge. People with Hypoparathyroidism, whether it is Iatrogenic (caused by surgical removal) or Idiopathic (without a defined cause), all have insufficient levels of parathyroid hormone causing the inability to regulate blood calcium levels. Although living with falling blood calcium levels is difficult, it is possible by taking a precarious combination of many medicines and supplements. Hypoparathyroidism causes extreme weakness among other unpleasant symptoms and can be life-threatening if calcium blood levels drop too low. ...

Background: The PI3K/protein kinase B (AKT) pathway is commonly activated in several tumor types. Selective targeting of p110β could result in successful pathway inhibition while avoiding the on- and off-target effects of pan-PI3K inhibitors. GSK2636771 is a potent, orally bioavailable, adenosine triphosphate-competitive, selective inhibitor of PI3Kβ.Methods: We evaluated the safety, pharmacokinetics, pharmacodynamics and antitumor activity of GSK2636771 to define the recommended phase II dose (RP2D). During the dose-selection and dose-escalation stages (parts 1 and 2), patients with PTEN-deficient advanced solid tumors received escalating doses of GSK2636771 (25-500 mg once daily) using a modified 3+3 design to determine the RP2D; tumor type-specific expansion cohorts (part 3) were implemented to further assess tumor responses at the RP2D.Results: A total of 65 patients were enrolled; dose-limiting toxicities were hypophosphatemia and hypocalcemia. Adverse events included diarrhea (48%), ...

In medicine, hypocalcaemia is the presence of low serum calcium levels in the blood, usually taken as less than 2.2 mmol/L or 9mg/dl or an ionized calcium level of less than 1.1 mmol/L (4.5 mg/dL). It is a type of electrolyte disturbance. It mainly occurs due to a deficiency of parathyroid hormone, inefficient parathyroid hormone, or deficiency of Vitamin D.
