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...

Mice with isolated GH deficiency (IGHD) due to GHRH receptor mutations live longer than their normal siblings with an extended healthspan, i.e., the period of life free from disabilities. Human IGHD individuals due to a mutation in the GHRH receptor gene from Itabaianinha, Brazil, has a normal lifespan with an extended healthspan (1). Our hypothesis is that their aging is accompanied by a delayed cognitive decline. Accordingly, we used the Literacy Independent Cognitive Assess...

Introduction: Pheochromocytomas are adrenomedullary catecholamine-secreting tumors. These account for <0.1% of all causes of hypertension and may be related to potentially fatal hypertensive crises. Can appear as sporadic tumors or associated with familial syndromes.Malignancy occurs in 15–20% of the cases and is characterized by local invasion or distant metastasis rather than capsular invasion. Tumor recurrence has been reported with a frequen...

Introduction: Graves’ disease is an autoimmune disease accounting for the majority of hyperthyroidism cases.Aim: We aimed to assess the interrelationships between cardiovascular risk factors, autoimmunity, insulin resistance and treatment in Graves’ disease.Material and methods: We measured free T3 (FT3), free T4 (FT4), TSH, thyrotropin receptor antibodies (TRAb), anti-thyroglobulin and anti-TPO antibodies, thyro...

Introduction: Thyroid dysfunction has been associated with cardiovascular events since it worsens atherogenesis, insulin resistance and dyslipidemia. Thyroid hormones and adipokines interact with each other to regulate metabolism. The impact of thyroid dysfunction on adipokines serum levels remains controversial.Objective: To evaluate the interrelations between thyroid function and cardiovascular risk factors as insulin resistance, lipid profile, inflamm...

Introduction: The interrelationship between autoimmune thyroiditis, Graves’ disease and plasma adipokines levels remains elusive.Aims: We aimed to compare the levels of adiponectin, resistin and PAI-1 levels in patients with autoimmune thyroiditis and Graves’ disease.Subjects and methods: We recorded thyroid function tests, BMI, the levels of total cholesterol (TC), HDL, LDL-cholesterol, triglycerides (TG), apolipoprotein...

Background: The diagnosis of Cushing’s syndrome (CS) remains a challenge in clinical endocrinology. Several screening tests have been proposed to establish hypercortisolism. Late-night salivary cortisol (LNSC) is used as screening tool, however, individualized cut-off levels for each population must be defined.Methods: Three group of subjects were studied: healthy volunteers, suspected CS and proven CS. All patients collected saliva at 23.00 h using...

Introduction: Cushing’s syndrome is an endocrinopathy characterized by glucocorticoids excess. Adrenalectomy is the recommend treatment for unilateral adrenal Cushing’s syndrome and is usually associated with resolution of the disease.Clinical Case: A 54-year old woman with central obesity (BMI 34.3 kg/m2), diabetes and hypertension had a left adrenal mass of 15 mm and characteristics suggestive of adenoma (Hounsfield unit of <10...

Introduction: Adrenal tumors are usually detected due to clinical manifestations of hormonal hypersecretion or incidental findings on imaging evaluation. Although most incidentalomas are non-functioning adenomas, it is important to appropriately evaluate such masses to exclude hormonal excess or malignancy.Case description: An 81-year old male was admitted to our hospital for fever with 15 days of evolution. The patient also presented chills and loss of ...

Introduction: Familial partial lipodystrophy (FPL) is an autosomal dominant disease characterized by selective loss of subcutaneous fat from the extremities and gluteal region, with lipohypertrophy of the face, neck and trunk. It is usually tightly linked with severe metabolic complications. FPL type 3 results from peroxisome proliferator-activated receptor gamma (PPARG) mutations.Case presentations: Fifty three-year-old woman, referred to endocrinology ...
