The 4th International Workshop for the management of asymptomatic PHPT included the presence of hypercalciuria (dUCa> 400 mg/day) and increased stone risk by biochemical stone risk profile as criteria for surgery. Our aim was to evaluate the complete stone risk profile in 176 consecutive patients with asymptomatic PHPT. We recorded clinical and biochemical data, including 24 hours urinary measurements of the following parameters: volume and pH, creatinine, calcium, magnesi...

Introduction: PHPT is a common endocrine disease characterized by hypercalcemia and different degree of osteoporosis and nephrolithiasis. PHPT arises in the context of an inherited disease in 5% of cases. Multiple endocrine neoplasia type 1 (MEN1) is the commonest cause of inherited PHPT. The main therapeutic approach for PHPT is surgery, however many patients refuse or have contraindications for surgery while others, in particular those with MEN1 PHPT, have persistent/relapsi...

Introduction: Targeted therapy with the multi-kinase inhibitor sorafenib is effective for treatment of differentiated thyroid cancer (DTC) unresponsive to RAI. Although kinase-inhibitors (KIs) are usually well tolerated, severe and even fatal adverse events are reported. Aim of the study was to assess incidence and characteristics of fatal events in patients with RAI-refractory DTC responsive to treatment with sorafenib.Design: A retrospective analysis o...

Introduction: Kinase-inhibitors (KIs) are effective for treatment of most aggressive endocrine cancers. The crucial point about treatment with KIs is that these agents are not curative and their effects are at best transitory and are always followed by a restoration of tumour growth and progression. Several retrospective and phase II studies demonstrated efficacy of both sorafenib and sunitib for treatment of iodine refractory differentiated thyroid cancer although results fro...

Autoimmune hypothyroidism due to thyroid stimulation blocking antibodies (TSB-Ab) is uncommon. When occurring in pregnancy, this condition may be responsible for feto-neonatal complications as a result of both maternal hypothyroidism and trans-placental TSB-Ab transfer to the fetus.Clinical case: September 2010: a 27 year-old woman was diagnosed with autoimmune severe hypothyroidism (TSH 325 mIU/l (n.v 0.4–4.0), FT4 1.54 pmol/l (n.v. 11.5...

Patients with hyperprolactinemia have impaired bone metabolism and bone mineral density (BMD) partially represents bone’s health.To evaluate vitamin D levels, PTH, Ca and P, BMD and bone morphometry in patients with prolactin-secreting pituitary adenomas.Forty-four patients (30 W, 40±11 years, BMI 27.6±5 kg/m2) underwent to lumbar and femoral DEXA, to vertebral morphometry by X-ray and was calculated the S...

Introduction: Primary empty sella (PES) is a frequent ‘incidental’ finding reported in 5–25% of general population and is associated with endocrine abnormalities in 8–60% of cases. In this collaborative multicentric study we evaluated cardiovascular risk by assessing clinical characteristics, glucidic profile and lipid parameters.Design: A total of 94 PES patients (39M-55F; mean age 50.3±0.9 years; mean BMI 28.9±0.5 kg/m<sup...

Introduction: Prader Willi Syndrome (PWS) is a genetic syndrome characterized by hyperphagia, morbid obesity, and many other endocrine alterations. PWS subjects present higher ghrelin levels. The cause of this increase as well as the modulation of ghrelin secretion at fasting and feeding in relation to other metabolic parameters in PWS is largely unknown. It has also been demonstrated that many ghrelin gene (GHRL) polymorphisms are associated with obesity, type 2 diabetes, and...

Oxidative stress is associated with chronic alcoholic abuse; it is also a mechanism involved in male infertility. To further investigate the relationships between these two conditions, we studied 6 patients with diagnosis of Alcohol Dependence (DSM-IV) during post-detoxification phase, who consulted our centre for infertility. We evaluated seminal parameters, hormone pattern, Total Antioxidant Capacity (TAC) and the lipophilic antioxidant Coenzyme Q10 (CoQ10), both in blood an...

Obesity is a well established risk factor for congestive heart failure. The existence of an ‘obese cardiomyopathy’ has been hypothesized, as the complex combination of the effects of both hemodynamic and metabolic alterations. Aim of this study was to analyze the effect of bariatric surgery on the early myocardial alterations detected in a group of severe obese patients by high frame rate integrated backscatter (IBS). Twenty severely obese patients (5 males, 15 femal...
