Introduction: Flash glucose monitoring (FGM) enables people with diabetes to regularly track their glucose levels without performing capillary finger-stick measurements (SMBG). Clinical studies have shown improvement in glycemic control, reduction of hypoglycemia, improvement in comfort and quality of life in people with type 1 diabetes (T1D) using this technology. In contrast to continuous glucose monitoring, FGM requires the performance of a scan to obtain the current glucos...

Objective: Polycystic ovary syndrome (PCOS) affects 5–20% of women of reproductive age worldwide and is associated with disorders of glucose metabolism. Hormone and metabolic signalling may be influenced by phytoestrogens, such as isoflavones. Their endocrine effects may modify symptom penetrance in PCOS.We investigated, whether women with PCOS and healthy controls differ in their capacity to metabolize dietary isoflavones and whether this capacity...

Objective: Menopausal transition has been associated with an increased risk of cardiovascular disease (CVD), mainly attributed to atherogenic dyslipidaemia, central obesity and insulin resistance. Whether arterial hypertension (AH) also contributes to menopause-associated CVD is currently unknown. The aim of this study was to systematically investigate and meta-analyze the best available evidence regarding the association between early menopause (EM) and AH risk.<p class="...

Objective: Abnormal mitochondria are well known in oxyphilic thyroid tumors but recent data also confirm profound mitochondrial alterations in other thyroid carcinomas. These changes are linked to the aggressiveness of the tumors. Our group recently demonstrated in an in vivo model, that inhibition of phosphoinositide 3-kinase (PI3K) signalling suppressed the invasive and metastatic behaviour of thyroid cancer cells. Here, we evaluated whether a modulation of PI3K sig...

Introduction: Cinacalcet is an oral calcimimetic indicated in treatment of primary hyperparathyroidism if patients do not accept surgery, do not carry out the surgical criteria, there is failure of previous surgery or serious comorbidity that makes surgery impossible.Methods: Descriptive study that included 20 patients with primary hyperparathyroidism who had complete at least 12 months of treatment with cinacalcet for different reasons (eight patients r...

Introduction: Generously supported by IPSEN)-->Prolactin (PRL) -secreting adenomas are about 40% of all pituitary adenomas. Their clinical symptoms are mainly related to development of secondary hypogonadism and/or tumor mass effects. Dopamine agonists (DA) are first-line drugs for prolactinoma patients due to their effectiveness in normalizing PRL levels and shrinking tumour mass. Surgery is an option for DA failure or tumour mass e...

Background: The initial management of hypercalcaemia is well described: aggressive intravenous rehydration and subsequent intravenous bisphosphonates if required. Isolated case reports document the use of haemo/peritoneal dialysis and haemofiltration in the management of severe hypercalcaemia. We report three cases that required renal replacement therapy to treat severe hypercalcaemia.Case series: A 21-year-old male presented with abdominal pain and vomi...

Familial glucocorticoid deficiency (FGD;OMIM 202200) results from the inability of the adrenal cortex to produce cortisol in response to ACTH stimulation. Half of all cases are caused by mutations in MC2R, MRAP or STAR. SNP array genotyping of FGD patients of unknown aetiology mapped a disease locus to chromosome 5p13-q12. Targeted exome sequencing of 5p13-q12 in one patient identified a homozygous mutation, p.Ala533Val, in nicotinamide nucleotide transhyd...

Introduction: Cytokines are produced in different tissues under physiological and pathophysiological conditions. The present study was performed to compare local concentrations of cytokines in subcutaneous adipose tissue and muscle using the open flow microperfusion (OFM) technique, as well as to investigate systemic effects of insulin on interstitial concentrations of these mediators.Methods: Ten healthy volunteers (age: 27±4 years, BMI: 22.6±...

Background: Fine Needle Aspiration (FNA) is currently the primary diagnostic procedure in diagnosing thyroid malignancy. The aim of this study was to report our experience with FNA, and its accuracy.Materials and methods: Retrospective analysis of 166 patients who were operated of thyroid nodule in our hospital from 2003 to 2008, all of them had a previous FNA cytology results. There were evaluated some clinical variables and the correlation with final h...
