The cut-off values able to differentiate between reactive or neoplastic C cell hyperplasia (CCH) or to predict sporadic medullary thyroid cancer (MTC) are still debated both for basal and stimulated calcitonin (bCT and sCT). Aim of the present study was to define the prevalence and the histological patterns of CCH in 15 patients with multinodular goiter (MNG), bCT>10 pg/ml and sCT levels >50 pg/ml. These data were compared with those from 16 patients with MNG and bCT l...

Patients with primary hyperparathyroidism (PHPT) are at risk of chronic kidney disease (CKD). PHPT patients (n=190, 146 females and 44 males, aged 59.7±14.2 years) and non-hypertensive, non-diabetic age- and sex-matched healthy controls were evaluated for serum cystatin C and creatinine. PHPT patients and controls with established CKD were excluded. Serum cystatin C was measured by immunonephelometric assay and calculation of estimated glomerular filtration rate ...

The fracture risk in primary hyperparathyroidism (PHPT) is partially independent of bone mineral density (BMD) and seems to depend on decreased bone quality, which is still reliably assessed only with invasive techniques. Trabecular bone score (TBS) is a grey-level texture measurement acquired during a dual X-ray absorptiometry (DXA) lumbar spine scan and it has been recently proposed as index of bone quality. This study is aimed to assess the role of TBS in predictin...
