Introduction: Adrenal myelolipomas are rare benign tumors. There has been an association of adrenal myelolipomas with other pathologies with hormonal hypersecretion, such as hypersecretion of adrenocortical hormone (ACTH) in Cushing’s Disease and Congenital adrenal hyperplasia. We report a case of acromegaly with co-existent large adrenal myelolipoma.Case Report: A 48-year-old caucasian male was referred to our Endocrinology consultation for an adre...

Introduction: Intra-thyroid metastases are infrequent, comprising only 1-3% of all thyroid malignancies. Renal cell carcinoma, particularly of the clear cell type (CCRC), stands out as the predominant kidney malignancy and the most common primary source of intra-thyroid metastases, often manifesting several years post-diagnosis. This report highlights two cases of CCRC metastasis to the thyroid, both featuring deceptive cytological findings.Case 1: A 60-...

Introduction: The anatomical and physiological changes induced by bariatric surgery (BS) can significantly impact the absorption and pharmacokinetics of orally administered medication. In particular, levothyroxine (LT4) dosage, given its dependence on patient’s weight and gastric pH for optimal absorption, is expected to change following BS. However, the literature is not unanimous and there is a void of longer-term studies. We aimed to compare LT4 dosage 4 years followin...

Insulin autoimmune syndrome (IAS) is a very rare cause of hypoglycaemia in western countries. One proposed mechanism is anti-insulin antibody capture of prandial insulin followed by the dissociation of insulin from anti-insulin antibody. The first objective was to study the relationship between glucose, insulin and C-peptide during a prolonged glucose load in two patients with active IAS. The second was to study the variation of these parameters between the active and the reco...

Introduction: Amiodarone is an antiarrhythmic iodine-rich drug, known to induce thyroid dysfunction both due to its high iodine content and through amiodarone-induced thyrotoxicosis (AIT), being this latter process classified into three different types. Type 1 is associated with increased thyroid hormone synthesis; type 2 is a destructive process with thyroid hormone release and type 3 is thought to be a mixture of the former two. Since treatment options are different, there h...

Introduction: Gestational diabetes (GD) is associated with a significantly higher risk of perinatal complications. It has been suggested that third-trimester (3thT) foetal abdominal circumference (fAC) determination is an important predictor of macrossomia and large for gestational age (LGA).Aims: The purpose of this study was to evaluate the association between the 3thT fAC percentile with birthweight (BW) and adverse neonatal outc...

The metabolic interplay occurring between the tumor microenvironment and cancer cells may represent a potential target for novel anti-cancer approaches. Among stromal components, adipocytes and adipose precursors have been shown to actively participate in tumor progression in several solid malignancies. In adrenocortical carcinoma (ACC), a rare endocrine neoplasia with a poor prognosis, cancer cells often infiltrate the fat mass surrounding the adrenal organ, enabling a possib...

Introduction: Scientific progress allowed an evolution on the therapeutic of diabetes mellitus. Continuous subcutaneous insulin infusion therapy (CSII) is one good example, but, beside patients motivation little is known about other psychological factors of success in this therapeutic and how they contribute to quality of life (QoL).Objectives: Determining some psychopathological predictors of CSII satisfaction and QoL improvement in patients on CSII the...

Introduction: Primary aldosteronism (PA) is a rare but underestimated cause of hypertension. PA has been associated with increased risk of malignancy through mechanisms involving up-regulation of the renin angiotensin system (RAS) promoting an enzymatic cascade influencing carcinogenesis. Recently, Microwave Ablation (MWA) has been established as an effective and safe minimal invasive treatment for Conn’s Disease.Aim: The authors present four clinic...

Introduction: The diagnostic gold standard for thyroid nodular disease is ultrasound-guided fine-needle aspiration cytology (US-FNAC), being the most accurate, cost-effective and minimal invasive preoperative test to distinguish benign from malignant nodules, aiming to resolve patient management. However, up to 30% of FNACs are classified as indeterminate nodules, turning difficult the decision on patient management to avoid unnecessary surgeries. The development of thyroid ca...
