Background: Obesity is associated with increased atherogenesis through alterations in lipids, among other potential factors. Some of those abnormalities might be mediated by insulin resistance (IR).Aims: To compare lipid and apolipoprotein profile between lean and obese women; to evaluate the influence of IR on lipid and apolipoprotein profile, in obese women.Methods: We studied 112 obese and 100 normal-weight premenopausal women w...

Introduction: Thyroid incidentaloma in 18F-FDG PET-CT is relatively common and the most focal uptake are benign. However, the risk of malignancy of thyroid lesions with focal uptake on 18F-FDG PET-CT is 34.8%. Metastasis to the thyroid is uncommon (less than 0.2% of thyroid fine needle aspiration – FNA - puncture findings), with renal neoplasms being the most frequently associated (48.1%) and, more rarely, those from the breast (7.8%).Case report: A...

Introduction: Adrenal oncocytoma (AO) and ganglioneuroma (GN) are rare causes of adrenal masses, corresponding usually to nonfunctional and benign tumors. However, 20% of the AO shows some elements of malignancy and 10–20% of them affect adrenal hormone production. GNs account for 0.3%-2% of adrenal incidentalomas, with punctate calcifications in CT imaging being highly suggestive. However, preoperative differential diagnosis remains challenging. Adrenal arterial emboliza...

Introduction: Thyroid hormones play an important role in bone metabolism. The potential action of prolonged levothyroxine therapy on bone mass reduction is still a matter of debate.Objective: The aim of the present study was to assess the effects of levothyroxine treatment on bone mineral density (BMD) and biochemical bone turnover markers.Methods: We determined thyroid function – TSH and free T4 (FT4), r...

Introduction: The bidirectional relationship of risk between breast cancer (BC) and thyroid cancer (TC) has been debated. Estrogens are proposed as agents implicated in the risk of developing TC promoting thyroid tumorigenesis. Therapies that reduce the effect of estrogens on their receptors in cancer cells are widely used.Objective: To correlate the use of hormonal therapy in BC with the prevalence of TC.Material and Methods: We p...

Introduction: The endocrine complications of COVID-19 remain largely unknown. Cases of central diabetes insipidus (CDI) have been reported after COVID-19, with hypophysitis being the most likely cause. COVID-19 vaccines potential adverse effects may mimetize some of these complications. We present a case of a woman who developed CDI one week after the 2 nd dose of BNT162b2 mRNA COVID-19 vaccine.Case Report: Female patient, 37 years old, with rheumatoid a...

Introduction: 17 alpha-hydroxylase deficiency (17OHD) is a rare autosomal recessive disease caused by mutations in the CYP17A gene, representing 1% of cases of Congenital Adrenal Hyperplasia (CAH). The accumulation of mineralocorticoids and the glucocorticoid effect of corticosterone induce high blood pressure (HBP) and hypokalemia.Clinical Case: A 44 year-old female reporting HBP since the age of 20 years and without chronic medication, presented at the...

Introduction: Graves orbitopathy is the major extrathyroidal manifestation of Graves Disease (GD). The approach depends on its clinical activity and severity. Treatment and referral to specialized centers, with Endocrinology and Ophthalmology, has a strong impact on the prognosis of Graves’ Disease (GD) and GO.Cases report: We report four cases of DG with OG. Their characteristics and clinical evolution are shown in Table 1.<table boarder="1" ce...

Introduction: Some studies suggest a possible link between autoimmune thyroid disease (AITD) and thyroid cancer (TC). However, existing data is inconsistent, and no consensus exists regarding this question.Objective: The aim of this study was to analyze the association between TC and AITD, namely Hashimoto’s thyroiditis (HT) and Graves’ disease (GD).Methods: We conducted a retrospective and observational study of all pati...

Introduction: Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a rare entity. Up to 1/3 of patients with incidental bilateral adrenal nodules presents biochemical evidence of hypercortisolism responsible for obesity, diabetes mellitus (DM), arterial hypertension or dyslipidemia. Its insidious course and nonspecific signs explain the underdiagnosis of this entity.Objective: To describe the case of a patient with metabolic syndrome (MS) with h...
