Article: Treatment with oral biphosphonates can increase the sensitivity of sestamibi radionuclide imaging in patients with primary hyperparathyroidism.
[show abstract] [hide abstract]
ABSTRACT: The sensitivity of 99mTc-sestamibi scan in detecting parathyroid disease in primary hyperparathyroidism (PHP) is almost 90%, and therefore facilitates successful parathyroidectomy. To enhance the diagnostic accuracy of the procedure, we repeated imaging with 99mTc-sestamibi in 15 patients with PHP and an initially negative (11 patients) or weakly positive (four patients) 99mTc-sestamibi scan after the administration of 10 mg of oral alendronate for 2 months. Serum calcium, phosphate and parathormone (PTH) measurements were obtained at presentation and after 1 and 2 months' treatment with alendronate. Eight patients with an initially negative 99mTc-sestamibi scan demonstrated at least one area of uptake in the repeated scan. Six of these patients underwent surgery and obtained a biochemical cure; a single adenoma was found in four and hyperplasia in the remaining two. In all four patients with an initially weakly positive 99mTc-sestamibi scan, the repeated scan demonstrated enhanced uptake and also revealed further areas of uptake. Two of these patients underwent surgery with a biochemical cure; an adenoma was found in one and hyperplasia in another. Compared with baseline there was a significant increase in PTH but not in calcium or phosphate levels during treatment with alendronate. We suggest that, in patients with PHP and a negative or weakly positive initial 99mTc-sestamibi scan, administration of oral alendronate may be associated with a positive repeated 99mTc-sestamibi scan and can thus enhance the sensitivity of the procedure.International journal of clinical pharmacology research 02/2005; 25(1):19-28. -
Article: Rapid intraoperative parathyroid hormone testing with surgical pathology correlations: the "chemical frozen section".
[show abstract] [hide abstract]
ABSTRACT: The classic surgical approach to patients undergoing parathyroidectomy for primary or secondary hyperparathyroidism has experienced a dramatic shift owing to preoperative localization of the affected glands and/or the use of rapid intraoperative parathyroid hormone (RI-PTH) assays, allowing for minimally invasive surgical excisions. Institutional experience with 141 patients who underwent parathyroidectomy aided by the use of RI-PTH is reviewed. The orientation provided by the intraoperative assay is essential in guiding the surgeon in these minimally invasive procedures, it helps reveal the cases of primary hyperparathyroidism with involvement of more than 1 gland, and it replaces the need for performing frozen sections, except for cases of secondary hyperparathyroidism.American Journal of Clinical Pathology 12/2004; 122(5):704-12. · 2.60 Impact Factor
