Neonatal Severe Primary Hyperparathyroidism



  • We present the case of an infant who underwent total parathyroidectomy at age 4 months in which intraoperative parathyroid hormone monitoring provided immediate confirmation of surgical cure.[ncbi.nlm.nih.gov]
  • Four cases of neonatal severe primary hyperparathyroidism occurred in three families; familial hypocalciuric hypercalcemia was present in each kindred.[ncbi.nlm.nih.gov]
  • Patient Presentation A male infant was referred to our institution for parathyroidectomy at 3.5 months of age.[pediatrics.aappublications.org]
  • He is Executive Advisory Editor of Bone Research (2013-present).[books.google.de]
  • Abstract Four cases of neonatal severe primary hyperparathyroidism occurred in three families; familial hypocalciuric hypercalcemia was present in each kindred.[nejm.org]
  • We describe a study of a boy with neonatal severe primary hyperparathyroidism (NSPHP) and alkaptonuria born to related parents of Turkish origin.[ncbi.nlm.nih.gov]
Severe Clinical Course
  • Paternal and de novo mutations tend to have a less severe clinical course due to the influence of maternal-fetal calcium regulations.[genedx.com]
Neonatal Jaundice
  • The updated coverage includes new information on fetal assessment, survival of premature infants, and perinatal asphyxia and new guidelines on neonatal jaundice.[books.google.de]
Hydrops Fetalis
  • Stay at the forefront of your field thanks to new and completely revised chapters covering topics such as: Principles and Practice l Immune and Non-immune Hydrops Fetalis l Amniotic Fluid Volume l Enhancing Safe Prescribing in the Neonatal Intensive Care[books.google.de]

  • Imaging of abnormal parathyroid glands is a critical part of the preoperative workup. Its role is to identify the position of enlarged glands in the neck or mediastinum and to differentiate between single and multiple gland disease.[karger.com]


  • Intensive medical treatment was unsuccessful and he was cured after total parathyroidectomy had been performed. It seems that total parathyroidectomy is the treatment of choice in cases of neonatal PHPT.[theijcp.org]
  • Total parathyroidectomy is the treatment of choice, so the surgeon must identify all the parathyroid tissue, including supernumerary and ectopic glands.[ncbi.nlm.nih.gov]
  • Make informed clinical choices for each patient, from diagnosis and treatment selection through post-treatment strategies and management of complications, with new evidence-based criteria throughout.[books.google.de]
  • By contrast, more common heterozygous mutations are associated with a benign variant termed familial hypocalciuric hypercalcemia, which generally requires no specific treatment. 1 – 3 Total parathyroidectomy is the standard treatment of NSPH 1 – 14 and[pediatrics.aappublications.org]
  • Surgery is the treatment of choice. While waiting for surgery, bisphosphonates offer a good alternative to deal with hypercalcemia.[pediatrics.aappublications.org]


  • 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]
  • Prognosis The regular monitoring required to ensure appropriate calcium levels means that the prognosis is challenging for many people. This may improve if synthetic PTH becomes widely available.[patient.info]


  • […] levels of parathyroid hormone, hypotonia and respiratory distress. 1 About 50 neonates with NPHP have been reported and it has been suggested as a possible contributor to a small number of cases of the Sudden infant death syndrome (SIDS) as well. 2 The etiology[jpma.org.pk]
