J Osteoporos . 2012 Apr; 2012:914214. PMID: 22523718
Introduction. Primary hyperparathyroidism (PHP) is characteristically determined by high levels of calcium and high or inappropriate levels of parathyroid hormone (PTH). Technological advances have dramatically changed the surgical technique over...

J Osteoporos . 2012 Apr; 2012:631243. PMID: 22496985
Surgical treatment of secondary (SHPT) and tertiary hyperparathyroidism (THPT) may involve various surgical approaches. The aim of this paper was to evaluate presternal intramuscular autotransplantation of parathyroid tissue as a...

Braz J Med Biol Res . 2005 Sep; 38(9):1383-7. PMID: 16138222
In contrast to most developed countries, most patients with primary hyperparathyroidism in Brazil are still symptomatic at diagnosis. However, we have been observing a change in this pattern, especially in...

Braz J Med Biol Res . 2003 Jun; 36(6):715-21. PMID: 12792700
Intraoperative parathyroid hormone (IO-PTH) measurements have been proposed to improve operative success rates in primary, secondary and tertiary hyperparathyroidism (PHP, SHP and THP). Thirty-one patients requiring parathyroidectomy were evaluated retrospectively...
