Women with Turners Syndrome (TS) have been shown to have reduced bone mineral density (BMD) but there is uncertainty about how this relates to fracture risk. The little data that does exist is conflicting, with one case series finding no difference compared to controls and one survey suggesting an increased risk of fracture particularly of the forearm. Proposed mechanisms for reduced BMD include short stature, oestrogen deficiency and bone dysplasia. In addition, fracture risk...

Rationale: Low level of vitamin D can results in secondary hyperparathyroidism (SH) that has been linked to increased cardiovascular risk in general population. However, the spectrum of cardiovascular risk associated with SH in HIV-infected adults remains uncertain. Our main aim was to determine its potential association with different markers of cardiovascular risk in HIV-infected adults.Methods: Cross-sectional study. Clinical data related to obesity, ...

Purpose: MicroRNAs (miRNAs) are a fundamental component of gene regulation mechanisms. Presently, altered miRNA patterns of expression have been documented in different human cancers, and they may explain the distinct behavior of pituitary adenomas (PA) and the differences between subtypes. miR-375 can target among other genes to IGF1 receptor (IGF1R) and participes in reprogramming cancer cell metabolism. The aim of this study was to assess the miR-375 role on pathogenesis of...

Purpose: The 2004 edition of the WHO text ‘Histological typing of endocrine tumors’ classified pituitary adenomas (PA) on the basis of their histological and immunohistochemical characteristics. Recent advances on the knowledge of the molecular patterns of these tumours may allow establishing a molecular classification with higher accuracy and specificity than previous one.Methods: Within the pale of the multicenter Spanish Molecular Registry o...

Introduction: Malignancy is an uncommon cause of adrenal incidentaloma in patients without a known diagnosis of cancer. The actual frequency of primary adrenal carcinoma in patients with adrenal incidentaloma is ~2–5%; another 0.7–2.5% have nonadrenal metastases to the adrenal gland. The presence of a nonadrenal primary tumour is exceptional and has been scarcely reported in medical literature.Case report: We present a case of 71-year-old male ...

Purpose: IGF receptor 1 (IGF1R) and epidermal growth factor receptor (EGFR) are receptors tyrosine-kinase (RTK) whose altered signaling are critical factors in development of many types of tumours. These RTK are some of the main targets of the microRNA miR-7. This important tumor supressor miRNA has the ability to inhibit the motility, invasiveness and anchorage-independent growth, suggesting a strong therapeutic potential in many types of cancer. Pituitary adenomas (PA) are a...

Background: Sunitinib (SUN) is a novel oral multitarget tyrosine-kinase inhibitor (TKI) that has demonstrated its efficacy in the treatment of metastatic renal cell carcinoma (mRCC). The thyroid dysfunction is one of the most common side effects of SUN. The mechanisms inducing thyroid dysfunction are still poorly understood.Aim: Identify the incidence, severity, ultrasonographic changes and pattern of response of thyroid function tests during treatment w...

Aim: To evaluate whether differences exist in terms of patient, radiological, tumour characteristics and surgical complications between malignant and benign thyroidectomy.Materials and methods: 184 correlatives cases of thyroidectomy during the period from October 2011 to October 2013 are analysed. Patient, ultrasound, tumour and complication characteristics are compared. Categorical data are reported as percentages. Characteristics between the two group...

Introduction: Factitious hypoglycemia results from surreptitious administration of insulin or insulin secretagogues. It can involve non-diabetic individuals with knowledge of hypoglycemiant drugs, or diabetics manipulating the doses.Clinical case: A 42-year-old women, type 1 diabetic since the age of 14, on intensive insulin therapy (A1C: 8.5%), was hospitalized for study of recurrent severe hypoglycemia in the last 2 months, despite successive insulin d...

Introduction: The syndrome of late-onset hypogonadism (LOH) is a clinical and biochemical syndrome associated with advancing age male, characterized by typical symptoms and decreased serum concentrations of testosterone, which can affect multiple organ systems and may impair quality of life. The prevalence of LOH syndrome is higher in certain patient groups, obese, diabetic and suffering from erectile dysfunction manifest LOH at higher rates than the general population.<p ...
