Introduction: Mutations in the aryl hydrocarbon receptor-interacting protein (AIP) predispose humans to pituitary adenomas, mostly GH and sometimes prolactin-secreting adenomas. Rodent models of heterozygous AIP loss provided mixed results, with little phenotype in heterozygote global knockouts to 80% in somatotroph-specific homozygote knockout animals. However, human patients with an AIP mutation often have mixed GH-PRL adenomas and, in a smaller pr...

Background: Low bone mineral density (BMD) and reduced sexual satisfaction have been reported in complete androgen insensitivity syndrome (CAIS). Nevertheless, conclusive data on the prevalence and on the optimal management of these conditions are still lacking.Aims: To assess bone and sexual health in adult women with CAIS with and without gonadectomy.Methods: Single-centre, prospective study of 27 adult CAIS (age 35.2±8.7 ye...

Diagnosis of Central Hypothyroidism (CeH) is commonly given when FT4 concentrations are below the lower limit of normal range. A reduction in FT4 concentrations greater than 20% was proposed in ETA 2018 Guidelines as an unphysiological fluctuation indicating the onset of milder forms of CeH with FT4 still within the normal range. Similarly, TSH-index was proposed to quantify thyrotrope reserve, hence as a tool to detect patients at risk of CeH. Here we verified the performance...

Background: Precocious puberty (PP) in girls is most frequently an idiopathic gonadotropin-releasing hormone (GnRH)-dependent PP, being thelarche the typical first sign. It is well established that increased dehydroepiandrosterone sulphate (DHEAS) levels are associated with premature adrenarche and may characterize PP too. However, its relationship with signs of hypothalamic-pituitary-gonadal (HPG) axis activation and oestrogen exposure is still to be elucidated.<p class="...

Aim: To evaluate the diagnostic effectiveness of the first commercially available computer-aided diagnostic (CAD) imaging analysis system.Methods: Ultrasound images of 300 thyroid nodules (135 malignant) acquired prior to surgical treatment were retrospectively reviewed by a thyroid expert, and then the classification of each image was compared to the classification rendered by an image analysis program (AmCAD-UT®). The American Thyroid A...

Aim: To evaluate the long-term efficacy of percutaneous ethanol injection treatment (PEIT) as an alternative to thyroid surgery in symptomatic thyroid cysts with a structured protocol.Methods: Seventy five subjects (48±12 years; 58% women) with symptomatic benign thyroid cysts relapsed after drainage were included. PEIT was conducted using the established procedure in our hospital, and the initial cyst volume, pain perceived by the patient and sympt...

The Glucagon-like peptide-1 (GLP-1) receptor is expressed in the lung having a very important role in the modulation of the Angiotensin Converting Enzymes (ACEs). ACE1 cleaves angiotensin-I into angiotensin-II, which is converted by ACE2 to Ang(1-7). Ang(1-7) has vasodilating effects. The Idiopathic Pulmonary Fibrosis (IPF) is characterized by excessive extracellular matrix deposition disrupting the alveolar architecture and physiology. IPF develops by a sequence of inflammati...

The Glucagon-like peptide-1 receptor is widely expressed in diverse tissues including the liver. GLP-1 contributes itself to the regulation of glucose homeostasis and has important effects in lipid metabolism even preventing liver steatosis induced by high fat diets.The aim of this study was to analyse the short-term effects of liraglutide on key enzymes of the hepatic energy metabolism.Thirty-six Sprague-Dawley young adult male ra...

Adverse events during gestation in rodents, results in an enhancement of immune function, including elevated levels of inflammatory cytokines in the brain. Liraglutide is a GLP-1 receptor agonists known to exert neuroprotective effects in brain. The aim of this study was to elucidate if liraglutide given to food restricted (FR) pregnant rats may prevent the deleterious effects of FR in the hippocampal inflammatory status of male and female pups at 21 days of age (D21). 20 Spra...
