Introduction: Bariatric surgery is currently considered the most effective treatment for morbid obesity. Laparoscopic gastric bypass (LGB) and laparoscopic sleeve gastrectomy (LSG) are the most widely used bariatric procedures today.Objectives: In this study we compared LGB and LSG in order to establish whether there is any superiority of one or the other in effectiveness and complications.Methods: We included all the patients who ...

Introduction: Bariatric surgery is currently considered the most effective treatment for morbid obesity, although rates of weight loss and comorbidities resolution differ among bariatric techniques and depending on preoperative factors.Objectives: In this study we analyse possible factors that influence the outcome of bariatric surgery (weight loss and improvement in metabolic comorbidities) in order to identify those patients most likely to benefit from...

Introduction: We present the results of chemoembolization used as a locoregional treatment for liver metastases (on a transplanted liver) from a bronchial carcinoid neuroendocrine tumor with stage IV disease progression.Case report: A 60-year-old man diagnosed of bronchial carcinoid NET in 2002, underwent surgery by lung lobectomy and excision of lymph node metastases. Treated also with somatostatin analogues (SA) after subsequent discovery of liver meta...

Sports authorities prohibited the use of EPO in 1988 and at present any analogue or mimetic is also included in the list of prohibited substances from the World Anti-Doping Agency (WADA). The presentation will summarize the main analytical strategies developed to identify the presence of recombinant erythropoietin (EPO) administered as a doping agent.Indirect evidence is based on the analysis of blood parameters (haemoglobin, haematocrit, reticulocytes, ...

Ghrelin was isolated from stomach by its ability to stimulate growth hormone (GH) release through the GH-secretagogue receptor (GHS-R1a). However, ghrelin/GHS-R expression in multiple tissues and tumor types suggested additional roles for this tandem. Ghrelin, a 28-aminoacid peptide, requires a unique O-acylation at its Ser-3 residue to bind GHS-R1a and release GH. Conversely, unacylated ghrelin (UAG), initially considered inactive, seems to play distinct metabolic role...

BackgroundThymic neuroendocrine tumor (THY-NET) accounts for almost 20% of multiple endocrine neoplasia type 1 (MEN1)-associated mortality. Diagnosis at early tumor stage is associated with improved survival.ObjectiveTo study the prevalence, clinical features and prognosis of THY-NET in MEN 1. To describe the overall causes of death among the registered MEN1 patients. To compare and discuss our results with t...

Non-functioning pituitary-adenomas (NFPAs) represent the most common pituitary tumor-type. To date, there are not clinical, biochemical, anatomo-pathological, immuno-histochemical or molecular parameters useful to predict their remission. Therefore, the aim of this study was to evaluate the potential relationship between the clinical, biochemical and pathological characteristics of patients with NFPAs, the expression profile of these tumours and the clinical outcomes during th...

Sex hormones act both as endocrine signals as well as local paracrine or autocrine factors in the nervous system. In addition to target to classical endocrine and reproductive brain areas, sex hormones and its metabolites affect learning and cognition and regulate the development and plasticity of brain regions that are not directly related to reproduction. Estrogen and progesterone exert neuroprotective effects in the central nervous system and may affect the onset and progre...

Growth hormone (GH)-producing pituitary cells (somatotropes) comprise a fundamental regulator for a plethora of relevant physiological functions, including somatic growth and whole-body metabolism, by controlling the function of different endocrine/non-endocrine targets. Synthesis and release of GH has been classically thought to be primarily regulated by central, dual neuroendocrine signals: i.e. GH-releasing hormone and somatostatin. However, it is progressively becoming evi...
