Somatotropinomas are benign pituitary tumors, with a heterogenous biological and clinical behavior. Tumor microenvironment reflects the interaction between tumor cells and the host immune system and may regulate tumor behavior and therapy outcome. We develop a scoring system that includes clinical, pathological and immune markers to early identify fg-SRLs resistant acromegaly pts. 43 acromegaly pts were included according the following criteria (1) first line treatment with su...

Acromegaly is associated with skeletal fragility and an increased prevalence of vertebral fractures (VF). In recent years several authors have tried to investigate the markers that can predict the risk of bone fragility in this endocrine disorder. Two different isoforms of the GH receptor (GHR) have been described so far, which differ in the presence or absence of a transcript of exon 3 of the GHR gene. Both isoforms produce a functional receptor, but the exon 3-deleted isofor...

Medullary thyroid carcinoma (MTC) accounts for 1%–2% of thyroid cancers and has a variable clinical course. MTCs present with locoregional metastasis in 50% of patients and distant metastasis in 10% to 15% at the time of initial diagnosis. The lungs, liver, and bone are common metastatic sites, and distant metastasis is known to be a poor prognostic factor for long-term oncologic outcomes. We present the long course case, under somatostatin analogues (SSA) therapy, of a 7...

Purpose: Osteopathy is an emerging complication of acromegaly characterized by increased bone turnover, deterioration in bone microarchitecture and high risk of vertebral fractures (VFs). In somatostatin analog (SSA)-resistant patients (pts), Pegvisomant (PegV) and Pasireotide LAR (Pasi) are used for acromegaly treatment, but their effect on skeletal health is still not defined.Methods: In a longitudinal international multicenter study, we evaluated inci...

Introduction: Incidentally discovered adrenal masses (incidentalomas) are common and in some cases differential diagnosis could be a challenge.Case report: A 55-years old woman presented with an incidental left adrenal mass of 36mm discovered on an abdominal ultrasound. As sole background she underwent resective surgery of an ovarian serous cyst. She denied symptoms like flushing, headache, diaphoresis or palpitations. Physical examination was irrelevant...

Mitotane is the only approved drug for the treatment of advanced adrenocortical carcinoma (ACC) and we recently demonstrated that a high expression of cytochrome P450 2W1 (CYP2W1) correlated with response to mitotane. The association between CYP2W1 alleles and a generally increased cancer risk is under debate. Aim of the study was to evaluate the frequency of CYP2W1 polymorphisms and its correlation with the response to mitotane treatment in ACC patients.<p class="abstext"...

Introduction: TSHomas are rare TSH producing tumors, whereas chronic autoimmune thyroiditis is a frequent condition. Patients with TSHoma are characterized by increased circulating levels of peripheral thyroid hormones, but when a chronic autoimmune thyroiditis is associated, they may be normal or low, making the diagnosis challenging.Case report: A 55 year-old woman, with previous medical history of obesity and impaired fasting glucose, was diagnosed of...

Introduction: Bilateral sampling of the inferior petrosal sinuses (IPSS) is considerate actually the best diagnostic test for Cushing.Patients and methods: We retrospectively reviewed our series of patients undergone IPSS for Cushing disease and we compared the difference between central and peripheral ACTH gradient in basal condition and after CRH stimulation in cases of localization of the tip of the catheters inside the inferior petrosal sinus or at t...

: Non-thyroidal-illness syndrome (NTIS) is present in chronic renal failure and considered an adaptive mechanism. However oxidative stress is linked to NTIS in a vicious circle, due to deiodinases alteration and negative effect on antioxidant levels or activity. One key antioxidant, protective toward ROS-mediated tissue damage, is extracellular superoxide-dismutase (ec-SOD), present in extracellular matrix and with a role in mediating nitric oxide-induced signaling. ec-SOD is ...
