The analogues of GLP-1(aGLP1) are a new class of anti-diabetic agents, administered subcutaneously for the treatment of Diabetes Mellitus type 2 (DM2). In the Portuguese market, there are two aGLP1 currently available: Liraglutide (once-daily administration) and Exenatide (once-weekly administration). They mimic the GLP-1, produced in the small intestine, stimulated by foods at this region, increasing the production of insulin, decreasing the satiety and slowing gastric emptyi...

Introduction: Cushing’s disease (CD) is a rare endocrine disorder characterized by endogenous hypercortisolism, which is associated with metabolic and psychiatric disorders. It is essential to understand the impact of normalization of serum cortisol in the evolution of these comorbidities.Aims: To evaluate the evolution of metabolic and psychiatric disorders after biochemical control of hypercortisolism in patients with CD.Met...

Introduction: Cushing’s disease (CD) presents a marked female preponderance, with a female-to-male ratio of 3–8:1, but whether this skewed gender distribution has any relevance to the presentation and outcomes of CD is not well understood.Aim: To evaluate sex-related differences in the presentation of CD, as regards: biochemical indices of hypercortisolism; complications of disease and outcomes.Methods: Observational, ret...

Objective: To characterise insulinoma diagnosed and treated in the period 1983–2014 in various hospitals in Spain.Methods: Inclusion criteria were the presence of biochemical and morphological criteria compatible with insulinoma and/or histologic demonstration of tumour.Results: Twenty-nine patients (23 women (79.3%); mean age 48.7±17.4 years (range, 16–74)) were recruited. In 26 (89.7%) cases the tumor was sporadic ...

Introduction: Cushing’s Disease results of corticotrophin (ACTH) hypersecretion from pituitary which increases cortisol production. WHO classified pituitary tumors as typical adenoma, atypical adenoma and carcinoma. Diagnostic criteria for an atypical adenoma include invasive growth, elevated mitotic index, Ki-67 labeling index greater than 3% and extensive p53 immunoreactivity.Case Report: Sixty-eight years-old man presented to our consult with his...

Non-alcoholic fatty liver disease NAFLD has been associated with androgen deficiency, yet in the majority of patients with non-alcoholic steatohepatitis NASH, androgens levels are normal. In contrast, women with polycystic ovarian syndrome PCOS, which is characterised by androgen excess, have evidence of increased liver fat. Our hypothesis is that androgen exposure to the liver may be crucial in the amount of lipid that can accumulate in hepatocytes. C3A human hepatoma cells w...

Background: Low plasma aldosterone after adrenalectomy due to aldosterone-producing adenoma (APA) and postoperative hypoaldosteronism recovery have been well described. However, prospective time course comparing simultaneously aldosterone and renin levels is still lacking.Aim: We prospectively studied clinical and biochemical findings emphasizing aldosterone and renin levels, in a cohort of patients with APA who underwent adrenalectomy in a single tertia...

Introduction: Germ cell tumors (GCTs) are classified as extragonadal if there is no evidence of a primary tumor in the gonads. They typically occur in the midline structures. Newly diagnosed adult cases of pituitary or pineal glands germinomas are very rare since most of the cases are diagnosed in the mid teens, presenting 14:1, on behalf of the male gender. The estimated incidence of this tumor in western countries is between 0.4–3.4%, being more frequent in the Asia.</p...

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: Noonan syndrome (NS) is a relatively common disease, clinically and genetically heterogeneous. It is characterized by facial dysmorphia, growth retardation, congenital heart disease, lymphatic dysplasia, among others. The diagnosis is clinical, according to van der Burgt criteria. In 61% of cases genetic mutations in the signaling pathway of RAS-MAPK are identified.Clinical case: BVM, male, NS suspected. At 3 years old sent to Pediatric Endoc...
