Introduction: Intraoperative quick PTH (iqPTH) monitoring is important in the treatment of primary hyperparathyroidism (pHPTH), allowing, together with preoperative localisation, the switch from routine bilateral neck exploration to limited gland excision.Aims: We checked the advantage of iqPTH for improving the cure rate of patients operated for pHPTH by using minimally invasive surgery (MIS).Materials and methods: Retrospective s...

Introduction: High-resolution ultrasound (US) allows the location of large parathyroid adenomas. These tumours should be however differentiated from thyroid nodules. For the confirmation of the parathyroid adenoma, we propose US-guided fine-needle aspiration biopsy (FNAB) of suspected nodules, with additional parathyroid hormone (PTH) analysis in the washout of the aspirate (PTH-FNA).Case report: A 51-year old woman with recently installed menopause and ...

Introduction: Graves’ disease (GD) has been related to a higher incidence of thyroid cancer. Thyroid nodules found in GD seem to have a higher risk for malignancy. The prognosis of thyroid cancer may be aggravated by the association with GD.Case report: We present the case of N.I, a 56-year-old woman diagnosed with multinodular goitre and overt hyperthyroidism for which therapy with carbimazole 40 mg/day was started. She was referred to our Endocrin...

Introduction: Idiopathic hypercalciuria is a risk factor for nephrolithiasis. Both renal stones and hypercalciuria are often associated with lower bone mineral density (BMD), but the relationship between these modifications is not completely understood. We aimed to evaluate some metabolic particularities possibly related to relapsing nephrolithiasis in young male patients.Methods: We performed a cross-sectional study including a group of 30 young male pa...

Published data regarding the role of FGF23 in primary hyperparathyroidism and its prognostic applicability are scarce and discordant.Aims: To assess FGF23 profile in patients with primary hyperparathyroidism undergoing surgery.Matherials and methods: Longitudinal study involving 48 patients aged 30–80 years with primary hyperparathyroidism caused by solitary parathyroid adenoma, submitted to parathyroidectomy. We evaluated FGF...

Parathyroid carcinoma (PC) is a rare endocrine tumor accounting for 0.5–6% or less in cases of primary hyperparathyroidism. According to The American Joint Committee on Cancer (AJCC) eighth edition, the histopathological criteria for PC include the presence of vascular invasion with capsular invasion and progression and/or metastasis to adjacent tissues. However, the small number of cases of PC makes it difficult to predict prognosis in the postoperative period of PC. We ...

Background: Vitamin D deficiency is frequently associated with primary hyperparathyroidism, but the impact of this association on disease evolution and complications is ill defined. Aims: to assess the role of vitamin D status on the metabolic profile and spectrum of complications at patients with primary hyperparathyroidism.Materials and methods: Transversal study involving 42 patients with primary hyperparathyroidism submitted to parathyroidectomy. We ...

Background: D hypovitaminosis and primary hyperparathyroidism frequently coexist. Secondary hyperparathyroidism reactive to D hypovitaminosis is difficult to be differentiated from primary hyperparthyroidism.Aims: To differentiate patients with D hypovitaminosis and secondary hyperparathyroidism.Materials and methods: Prospective study involving 71 patients admitted in our department for 1 year with the initial diagnosis of primary...

Aims: We wanted to evaluate the correlations between the volume of the surgically removed parathyroid adenoma and the presurgical metabolic profile of patients diagnosed with primary hyperparathyroidism.Materials and methods: Prospective multicentric study, enrolling 52 patients with primary hyperparathyroidism from two medical units, proposed for surgery. Serum calcium and PTH were evaluated in all patients before surgery, and 25OH-D3 was measured only ...
