    Nuclear Medicine Methods for Evaluation of Abnormal Parathyroid Glands in Patients with Primary and Secondary Hyperparathyroidism.
    Folia Med (Plovdiv) 2017 Dec;59(4):396-404
    4Complex Oncology Center, Plovdiv, Bulgaria.
    Considered rare disease in the past, primary hyperparathyroidism (PHPT) has dramatically increased in incidence over the past thirty years with the introduction of routine calcium measurements; it is now approximately 42 per 100 000 persons. By far, the most common lesion found in patients with PHPT is the solitary parathyroid adenoma, occurring in 85%-90% of patients, while in the rest 10%- 15% primary hyperplasia of the parathyroid glands is present. Currently, the most widely used surgical approach is minimally invasive parathyroidectomy which is associated with less post-surgery complications and shorter operation time. Read More

    Normocalcemic primary hyperparathyroidism associated with progressive cortical bone loss - A case report.
    Bone Rep 2017 Dec 10;7:152-155. Epub 2017 Oct 10.
    Roger Williams Medical Center, 825 Chalkstone Avenue, Providence, RI, USA.
    The existence of normocalcemic primary hyperparathyroidism (NPHP) was acknowledged at the Third and Fourth International Proceedings on primary hyperparathyroidism PHPT but data relating to its clinical presentation, natural history, and skeletal status were limited and there was no information nor guidelines as to definitive therapy. Herein are reported biochemical, hormonal, and densitometry data in a postmenopausal woman seen initially for osteoporosis who was found to have increased serum PTH levels and normal serum total and ionized calcium levels without evidence of secondary hyperparathyroidism. Over a seven year period, the patient exhibited continuing preferential cortical bone loss at the one-third site of the radius in the face of relatively stable readings at the lumbar spine and hip that led to a subtotal parathyroidectomy for parathyroid hyperplasia with resultant normalization of serum PTH.

    Background: The effect of altered parathyroid hormone metabolism in renal insufficiency on intraoperative parathyroid hormone monitoring during parathyroidectomy is not well known. This study evaluates operative outcomes in patients undergoing parathyroidectomy guided by intraoperative parathyroid hormone monitoring for primary hyperparathyroidism with mild and moderate renal insufficiency.

    Methods: A retrospective review of prospectively collected data in 604 patients with sporadic primary hyperparathyroidism undergoing parathyroidectomy guided by intraoperative parathyroid hormone monitoring was performed. Read More
