Introduction: Insulinomas are the most frequent cause of endogenous hypoglycaemia. 90 to 95% of these are benign. Surgical enucleation or resection is the standard treatment. Medical therapy focuses mainly on the use of diazoxide with few alternatives in patients with high surgical risk.Case-report: Female patient, 89 years-old, non-diabetic, with previous history of acute myocardial infarction, stroke with motor sequelae, pacemaker carrier and severe ao...

Introduction: The diagnosis of infected ulcer is mainly clinical. The goals of the microbiological studies are identification of the pathogen and evaluation of susceptibility to antibiotics to minimize exposure to drugs and selection of resistant strains.Methods: Retrospective cohort study; Data collection: 1 January 2010 to 31 December 2014. Were included wound samples of aspirate, nonsurgical/surgical exudate, pus from abscesses and bone fragments from...

Introduction: The complications related to ulcerated foot lesions are a common cause of hospitalization among diabetics. Diabetic foot infection is associated with high morbidity and is the most common precipitating factor to precede amputations of the lower limbs.Methods: Retrospective, cohort study; were included 200 patients from the Diabetic Foot consultation of the Endocrinology Department between 1 January and 31 August 2015. Ulcerated lesions were...

Introduction: Type 1 Diabetes (DM1) is associated with a destructive autoimmune process of pancreatic b-cells. The presence of anti-islet cells (ICA) antibodies (Ab), as well as for distinctive antigens – GAD65, IA2 or Insulin (IAA) - is related to the disease development.Aim: To evaluate the effect of DM1 antibodies on the measures of glycemic variability (GV) obtain through continuous glucose monitoring (CGM).Materials and m...

Introduction: Thyroid hormones modulate the insulin sensitivity and glucose metabolism. The interrelation between thyroid autoimmunity, thyroid function, glucose metabolism and cardiovascular risk factors remains uncertain.Methods: We recorded thyroid function tests, BMI, IR markers comprising the Homeostasis Model Assessment for insulin resistance (HOMA-IR and HOMA-B), the Quantitative Insulin Sensitivity Check Index (QUICKI), HISI (Hepatic Insulin Sens...

Introduction: Ectopic adrenal tissue (EAT) occurs in less than 1% of adults, more commonly in males. It may be found anywhere along the path of embryogenic migration, usually in the kidney and retroperitoneal fat. We report a case of EAT in the fallopian tube, a particularly rare localization.Case: We present a 57-year-old female with a known medical history of nephrolithiasis and previous ectopic pregnancies. The patient was submitted to a laparoscopic ...

Introduction: Long-acting (LA) somatostatin analog (SSA) therapy is a common first-line medical treatment for acromegaly and NETs. There are limited real-world data on patients’ injection experience with the latest LA SSA devices/formulations.Aims: To compare the injection experience of patients with acromegaly or NETs who were receiving treatment with LAN prefilled syringe vs OCT syringe.Methods: A 2021 e-survey of adults wit...

Liver-expressed antimicrobial peptide 2 (LEAP-2) has been recently characterized as an endogenous GHSR1a antagonist. LEAP-2 is produced mainly in the liver, and it was described that an acute ghrelin administration blocks food intake, GH release and normalize glucose levels during chronic caloric restriction. For this reason, it could be considered as a key endocrine factor in the regulation of systemic energy metabolism. Nevertheless, the exact mechanism of action is still un...

The majority of adrenocortical tumors (ACT) are benign and hormonally non-functioning, in contrast to adrenocortical carcinomas (ACC), which are rare and usually very aggressive tumors. The differential diagnosis between these two entities is mainly based on unspecific and subjective criteria, contributing to the inaccuracy of diagnosis. Due to ACC molecular and biological heterogeneity, prognostic factors have a limited capacity to predict ACC clinical outcomes, leading to an...

Visceral adipose tissue (VAT) metabolic fingerprints differ according to the individual’s BMI and glycemic status. GLP-1 and Glucagon are two hormones that participate in energy homeostasis and glycemic control. Dual GLP-1/Glucagon agonists are a drug class under development for obesity and diabetes treatment. Although the pancreas and the liver are considered major GLP-1 and glucagon targets, these hormones act in other tissues, which could contribute for its effects on ...
