Failure to Thrive
Abstract Neonatal hyperparathyroidism usually presents as a "failure to thrive" syndrome. It may be transmitted as an autosomal dominant trait and may involve more than one offspring. [ncbi.nlm.nih.gov]
Infants with NSHPT often exhibit polyuria, dehydration and hypotonia associated with a history of failure to thrive, respiratory distress, irritability, lethargy, constipation, and delayed neuropsychological development. [iofbonehealth.org]
Bradford WD, Wilson JW, Grade JT (1973) Primary neonatal hyperparathyroidism-An unusual cause of failure to thrive. Am J Clin Pathol 59:267 Google Scholar 3. [link.springer.com]
Symptoms appear in infancy and include extreme hypercalcemia, failure to thrive, hypotonia, skeletal demineralization, and severe parathyroid hyperplasia. Some de novo mutations may cause a mild or transient version of NSHPT. [parathyroid.com]
Failure to thrive, vomiting, and hypoglycemia may be seen. [genico.ch]

Suggestibility
Hyperparathyroidism was found in their father, suggesting autosomal dominant inheritance. The disease is fatal unless recognized early and treated. The characteristic pathological change is chief cell hyperplasia of the parathyroid glands. [ncbi.nlm.nih.gov]
Recurrent allelic gains were seen on chromosomes 1q and 16, suggesting the presence of parathyroid oncogenes on these chromosomes. [cancerindex.org]
[…] concentrations with hypocalcemia and high iPTH levels suggest vitamin D deficiency). [clinicaladvisor.com]
Screening for Primary Hyperparathyroidism Screen only those patients with known hypercalcemia; history, symptoms, or signs suggestive of hypercalcemia; and medical conditions in which primary or secondary hyperparathyroidism is known to occur. [enotes.tripod.com]
Thus, Low or even low-normal PTH concentrations are inappropriate and suggest hypoparathyroidism. An undetectable PTH concentration suggests idiopathic hypoparathyroidism. [merckmanuals.com]
Workup
Workup Laboratory studies Total serum calcium and albumin levels or ionized calcium levels should be measured. Hypercalcemia should be documented on more than one occasion before a diagnostic workup is undertaken. [emedicine.medscape.com]

Prolonged hypercalcaemia may aggravate arteriosclerosis, cardiac valve sclerosis or nephrolithiasis and therefore prolonged hypercalcaemia should be avoided when One-Alpha is used in these patients. [medicines.org.uk]

Nearly all patients are symptomatic at presentation and end-organ damage (nephrocalcinosis, nephrolithiasis, acute pancreatitis, or bone involvement) is common. [hawaii.edu]

Hypocalciuria
NSHPT is characterized by parathyroid hyperplasia, marked and symptomatic PTH-dependent hypercalcemia, relative hypocalciuria, and bone fragility. [iofbonehealth.org]
Diagnostic methods Biologically, children present with extremely high serum calcium and serum PTH levels and a relative hypocalciuria, but in some cases they present with a markedly elevated calciuria. [rarediseases.info.nih.gov]
FHH is characterized by hypercalcemia, hypocalciuria, hypermagnesemia, and normal to low levels of parathyroid hormone (PTH). FHH is caused by loss-of-function mutations in the CASR gene. [parathyroid.com]

Calcium Increased
Signs and symptoms of hypercalcemia in most patients are minimal; however, as the level of calcium increases, the symptoms will be more pronounced. Acute (rapid) increases in calcium levels will cause more severe symptoms. [emedicinehealth.com]

Prognosis Patients can die from complications of hypercalcemia during the neonatal period from respiratory distress and dramatic hypercalcemia. Last updated: 5/16/2014 [rarediseases.info.nih.gov]
NSHPT can be fatal if partial or total parathyroidectomy is not carried out within the first several weeks of life, with a good short-term prognosis after surgery and rapid involution of bony abnormalities. [iofbonehealth.org]
The disorder carried a grave prognosis if not diagnosed promptly and managed surgically. [link.springer.com]
The prognosis is excellent for many of the other causes of hypercalcemia, if the underlying cause is diagnosed and treated. [emedicinehealth.com]
Etiology
The text presents information on etiology, molecular mechanisms, diagnosis, localization studies, surgical, treatment options, and outcomes. [books.google.com]
Etiology NSHPT is associated in most cases with homozygous inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR), a member of the subfamily of G protein -coupled transmembrane receptors. [rarediseases.info.nih.gov]
After acute symptoms have resolved, an intravenous infusion of calcium should be initiated at a rate to keep the serum calcium levels in the low normal range while an investigation of the etiology ensues. [hawaii.edu]
The etiology of MEN1 syndrome is menin inactivation. [hormones.gr]
In both cases the diagnosis was initially suspected from chest radiographs which were obtained to assess the etiology of fever and respiratory distress in one case and heart murmur in another. [link.springer.com]

Prevention
How Can I Prevent Hypercalcemia? Hypercalcemia cannot be prevented, but early detection of the condition allows for normalization of calcium levels and leads to an early medical evaluation to determine the cause. [emedicinehealth.com]
Precautions are taken to prevent seizures or larynx spasms. The heart is monitored for abnormal rhythms until the person is stable. [en.wikipedia.org]
Cinacalcet has been well tolerated by 28 patients, whereas five individuals complained of heartburn and grade 1 nausea, which did not prevent the completion of the study. [scinapse.io]
