Background: Incidentally discovered adrenal tumours have become a common clinical problem. The presence of an adrenal incidentalomas has been associated with an increase incidence of several cardiovascular risk factors. These abnormalities are more frequent in patients with clinical and subclinical hypercortisolism, nevertheless some studies have reported an association between nonfunctioning adrenal incidentalomas (NFAIs) with increased insulin resistance and cardiovascular r...

Introduction: Myxedema coma is the most serious manifestation of hypothyroidism and, although rare, it is associated with high mortality. Amiodarone therapy can lead to thyroid dysfunction, either hyperthyroidism or hypothyroidism; however, in this context, myxedema coma is rare. Amiodarone discontinuance is not recommended in hypothyroidism’s treatment, but may lead to its resolution if there is no pre-existing thyroid pathology. We present a clinical case of amiodarone-...

Introduction: Masculinizing Gender-Affirming Hormone Therapy (GAHT) generally aims to induce testosterone levels equivalent to those of cisgender men and to reduce estradiol levels. There are no studies about bioavailable testosterone in this population.Aims: To determine the variation of the serum levels of sexual hormones in transmasculine people under GAHT and study the correlations between them and with BMI.Methods: Longitudina...

Background: The lack of circadian rhythm is a marker of Cushing’s syndrome (CS). Therefore, salivary cortisol rhythm has been suggested for studies on the hypothalamic–pituitary–adrenal (HPA) axis. Late-night salivary cortisol has been used recently by many centers as a first line diagnostic test for CS, yet its accuracy is still on debate.Aim: To evaluated the performance of morning and late night salivary cortisol in patients with CS and...

Introduction: Multiple endocrine neoplasia (MEN) syndromes are rare entities characterized by the occurrence of tumors involving two or more endocrine glands in a single patient. These syndromes are classified as type 1 or 2 according to specific phenotypic characteristics. MEN2 encompasses three different subtypes: MEN2A, MEN2B and familial medullary thyroid carcinoma. More recently a syndrome related to mutations in the CDKN1B gene has been described – the syndrome of m...

Introduction: This study presents four clinical cases of lipodystrophies, which are a group of rare and heterogeneous diseases characterized by the decrease or lack of adipose tissue (AT) accompanied by metabolic complications.Clinical cases: 1) 59-year-old woman with partial familial lipodystrophy, type 7 (OMIM #606721): Diagnosis of suspected type 1 diabetes (DM) at 28 (treated with insulin with poor control), class 1 obesity and hypertriglyceridemia. ...

Introduction: The development of new pharmacological classes for type 2 diabetes (T2D) treatment with extra-glycaemic benefits has led to the update of the treatment algorithm, presenting new effective alternatives to patients’ insulinization. The present study aims to evaluate the evolution of prescription and its impact in metabolic control of patients enrolled on an educational diabetes program of a tertiary hospital.Objectives: To evaluate trend...

Introduction: The need to fast for the determination of lipid profile has been discussed in the past years, for several reasons – i) most of the day time is spent in a postprandial state; ii) the lipid concentrations seem to be only slightly affected by a normal meal; both fasting and postprandial can predict cardiovascular risk.Aim: Determine the influence of normal food intake on the lipid profile of diabetic patients.Method...

Introduction: Adrenal incidentalomas are asymptomatic adrenal masses found accidentally during routine examination, not intended for adrenal pathology evaluation. The functionality of these lesions must be further investigated. Rarely, bilateral adrenal nodular hyperplasia can be detected in a patient with Cushing’s disease. The authors present the case of a patient with possible autonomous cortisol secretion of adrenal origin that eventually emerged as Cushing’s dis...

Introduction: Non-islet cell tumor induced hypoglycemia (NICTH) is a paraneoplastic phenomenon involving many types of tumors. It is associated with the secretion of incompletely processed precursors of IGF-2 resulting in a persistent insulin-like activity and hypoglycemia. Most commonly, IGF-2–linked hypoglycemia has been observed in patients with solid mesenchymal or epithelial tumors. Typically, elevated IGF-2 levels are associated with suppressed plasma levels of insu...
