Teriparatide (TPTD – recombinant human parathyroid hormone 1–34) markedly increases bone mineral density (BMD) and reduces fracture risk. Sequential treatment with an antiresorptive agent is believed to preserve or further increase BMD. Strontium ranelate (SR) is thought to uncouple bone remodeling resulting in increased BMD and reduced fracture risk. In this prospective study, we aimed to evaluate the effect of SR on BMD in women with established osteoporosis previo...

Objective: To assess the regulation of parathormone (PTH) and serum calcium (s-Ca) in patients, on follow-up over a long time period of four years, who have primary hyperparathyroidism (pHPT) and whose condition is non-operable or who are not willing to undergo surgery.Methods: Initially, 17 patients with documented pHPT were recruited and treated with calcimimetic cinacalcet at a dose calculated according to s-Ca levels (≤11 mg/dl or >11 mg/dl...

Introduction: Hajdu Cheney Syndrome (HCS) is a rare genetic autosomal dominant disorder affecting multiple organ systems, characterized by distinctive facial features, acroosteolysis and severe osteoporosis. In a limited number of cases, the disease appears in association with polycystic kidney disease (PKD) or Crohn’s disease (CD). Splenomegaly has also been reported. Heterozygous gain-of-function mutations in NOTCH2 gene have been confirmed to be the cause of H...

Introduction: Adrenal incidentalomas (AIs) constitute an emerging clinical entity due to the increased use of abdominal imaging for diagnostic purposes.Objective: To investigate the morphological and hormonal alterations of AIs in a cohort of patients, who were followed-up in a single centre.Methods: Sixty-four patients (22 males and 42 females; mean age 61.6±1.2 years), with AIs and follow-up of 3.1±0.4 years (range 0&#1...

Introduction: Bisphosponates have long been used with success in the treatment of Paget’s disease of bone (PDB). The aim of this study was to evaluate the early (up to three months) and late (at twelve months) scintigraphic, biochemical and clinical response to a single intravenous infusion of zoledronic acid (ZOL) in patients with PDB serially assessed for one year.Materials and methods: Nine patients with 30 bone lesions due to PDB were prospectiv...

Estrogens play an important role in male physiology. We investigated the possible association of four single nucleotide polymorphisms in estrogen receptor α (ER1) and Estrogen Receptor β (ER2) genes with circulating levels of sex steroids and Sex Hormone Binding Globulin (SHBG) in men.SHBG, total and calculated free testosterone (TT and cal FT), estradiol (E2) and free estradiol (FE2) were determined in a population based cohort of 170 apparent...

Background: Previous research has demonstrated positive effects of Orthodox fasting (OF) and time restricted eating (TRE) on body weight (BW). However, little is known about the late, metabolic effects of the two diets.Methods: 29 overweight adults followed a hypocaloric diet based on OF. A hypocaloric, TRE plan (eating between 08:00 to 16:00 h) was followed by 16 BW-matched participants. Anthropometric, glycemic and inflammation markers and serum lipids...

Introduction: Low levels of 25-hydroxy-vitamin D [25(OH)D] have been recognized as a new cardiovascular disease risk factor. Conflicting data exist regarding the effect of statins on 25(OH)D levels and glucose metabolism.Methods/design: This was an open-label randomized prospective comparative study evaluating the effects of atorvastatin and rosuvastatin at equivalent doses on 25(OH)D levels, glucose homeostasis and systemic inflammation in non-diabetic ...

Although vaspin is regarded an insulin-sensitizing adipokine, its role in gestational diabetes mellitus (GDM) is currently unknown. We aimed to evaluate serum vaspin levels and their correlation with insulin resistance in women with and without GDM. Forty-four women with GDM (GDM Group 20 managed with diet only (GDM-diet) and 24 with diet plus insulin (GDM-insulin)) and 44 age-matched pregnant women with normal glucose tolerance (control group) were studied. Serum glucose, lip...

Background: Fine-needle aspiration biopsy is the ‘gold standard’ in the preoperative management of thyroid nodules.Aim: The aim of this study was to investigate whether serum TSH is a predictor of thyroid malignancy in patients presenting with thyroid nodules.Subjects and methods: About 565 patients without overt thyroid dysfunction, who presented with palpable thyroid nodule(s) between 1988 and 2004 and underwent at leas...
