Bone loss is a frequent complication of aromatase inhibitors (AIs) therapy in women with breast cancer. Bone-active drugs are effective in protecting the skeleton from detrimental actions of AIs. However, bone mineral density (BMD) was the primary end-point in most of published studies, whereas data on fractures were scant and mainly limited to denosumab. In this prospective study, we investigated the effects of denosumab, oral bisphosphonates and intravenous zoledronate on ri...

Background: There is growing awareness of skeletal impairment in individuals with Klinefelter syndrome (KS), involving both quantitative and qualitative alteration of the bone as well as an increased prevalence of vertebral fractures (VFs). Beyond hypogonadism, considerable evidence suggests that other factors may be responsible for the skeletal fragility observed in these patients. Abnormal body composition is a common finding in KS subjects, characterized by an unfavourable ...

Background: Osteoporosis is characterized by reduced bone mass and a compromised bone microstructure, leading to increased bone fragility and fracture risk. Currently, the gold standard for diagnosis is the bone mineral density (BMD) measurement by DXA. However, approximately half of fragility fractures occurs in the context of normal or slightly decreased BMD values.Protocol: In this cross-sectional study, we performed an artificial intelligence (AI)-ba...

Context: Available data on the natural history of pituitary incidentalomas (PI) are not strong enough to draw any evidence-based conclusion on timing and length of follow up of these masses, due to heterogeneity and low sample sizes.Objective: To describe the characteristics and the natural history of PI using data from a large cohort of patients investigated in two Italian Pituitary Centers.Patients and methods: Retrospective stud...

Dopamine receptor type 2 (DRD2) agonists (DAs) are the first-choice treatment for PRL-secreting pituitary tumors due to their efficacy in reducing tumor size and hormonal secretion. However, DAs are poorly effective in non-functioning pituitary tumors (NFPTs), despite most of them express DRD2. No correlation between DAs clinical responsiveness and DRD2 expression was found, suggesting post-receptor alterations underlying resistance. DRD2 signaling pathways that control cell p...

In this observational, retrospective, multicenter study, we analyzed data from 300 patients with pituitary incidentaloma followed in two Italian Hospital Center. We observed a predominance of female patients (65%), with an a mean age at diagnosis of 49 years (higher in men than women, 57 vs 45 years old). The main reason to perform imaging were neurological symptoms not related to the presence of adenomas (56%). Most cases were microadenomas (56%), and macroadenomas were more ...

Klinefelter syndrome (KS) is a frequent form of male hypogonadism that may be associated with a series of comorbidities potentially affecting quality of life and survival. As a matter of fact, KS was shown to negatively impact skeletal health. However, the studies so far published on this topic were mainly focused on evaluation ofbone mineral density (BMD) and bone microstructure, whereas data on fracture risk are still lacking. In this cross-sectional study, we evaluated for ...

Chronic exposure to GH hypersecretion may alter the physiological balance of the spine through inducing degeneration of intervertebral discs and impaired trophism of facet joints. Moreover, GH in excess may also cause profound deterioration in bone microstructure with consequent increase in risk of fragility vertebral fractures (VFs). In this cross-sectional study,we evaluated for the first time in acromegaly the association between spine imbalance and VFs. Thirty-eight patien...

Introduction: Klinefelter syndrome (KS) is known to be associated with an increased risk of venous thromboembolism and arterial thrombosis, but the aetiology behind this prothrombotic status has not been fully elucidated. The aim of this study was to cross-sectionally investigate the coagulative state in subjects with KS compared to age-matched healthy males.Methods: Coagulation factors assessment, clinical characteristics collection and thrombin generat...

TNM 8th edition introduces changes in the staging of patients with differentiated thyroid carcinoma (DTC). This study aims at assessing the ability of TNM 8th edition in predicting structural recurrence of DTC.480 DTC patients were retrospectively evaluated by 7th and 8th editions of TNM staging systems in relationship with risk stratification, response to therapy and recurrence of disease as defined by 2015 American Thyroid Association (ATA) guidelines. As compared to the 7th...
