Introduction: Adrenal incidentalomas are a frequent finding (1.4-7.3% on abdominal CT) and increasingly common with age, obesity, diabetes and hypertension. When approaching adrenal masses, clinicians should exclude malignancy and hormonal hypersecretion. Black adrenal adenomas (BAA), first reported in 1938, are rare benign adrenocortical tumours with black/brown appearance, containing lipofuscin. Most are non-functional, rarely inducing hypercortisolism. We present a case of ...

Introduction: Pseudohypoparathyroidism (PHP) refers to a heterogeneous group of disorders that have in common end-organ unresponsiveness to parathyroid hormone (PTH). The most frequent form, PHP type 1, results from different genetic/epigenetic changes in the GNAS gene.Case 1: Woman, 25 years-old, sent to Endocrinology from Genetics consultation after her daughter had been diagnosed with PHP type 1a (heterozygous pathogenic variant at exon 13 of...

Introduction: Amyloidosis results from deposition of insoluble proteins in the extracellular space. It can be both primary or secondary to chronic inflammatory diseases. Although microscopic thyroid involvement is common, cases in which it becomes clinically evident (amyloid goiter) are rare.Case report: Woman, 45 years. In 2009, she was diagnosed with Crohn’s disease after Bartholin’s gland abscess excision and evaluation for weight loss, anem...

Introduction: Hypovitaminosis D is a biochemical change with high prevalence among the population, especially in obese patients. Its function more known relates to bones metabolism, although recently, many functions have been described.Methods: A descriptive cross-sectional study, which included women over 18 years old with BMI equal or superior of 25 kg/m2. Anthropometric measurements were obtained: weight, height, BMI, waist circumference, h...

Introduction: Congenital hypogonadotropic hypogonadism (CHH) is a rare disorder. It can be sporadic or familiar and is divided into anosmic hypogonadotropic hypogonadism (Kallmann syndrome - KS) and congenital normosmic isolated hypogonadotropic hypogonadism (idiopathic hypogonadotropic hypogonadism ‐ IHH). A growing number of genes are involved in its etiology, suggesting the heterogeneity and complexity of this condition.Cases Reports: Six cases...

Introduction: The association of hyperthyroidism and thyroid cancer (TC) is controversial with prevalences in the literature varying from 1.6 to 32.8%. The aim of this work was to evaluate the prevalence of TC in hyperthyroid patients submitted to surgery and to find differences between the tumors according to the type of hyperthyroidism.Material and methods: retrospective study to evaluate clinical and histopathological data of all hyperthyroid patients...

Introduction: LDL cholesterol (LDL-C) is a major risk factor for atherosclerosis. The Friedewald formula (FF) is limited by hypertriglyceridaemia. We aimed to correlate serum LDL-C measured by direct assay with serum LDL-C estimated by several formulas: Friedewald (FF): LDL-C=CT-HDL−TG/5; Tsai (TsaiF): LDL-C=TC-HDL−TG/8 (TG/8 represents very-LDL-C); DeLong (DeLongF): LDL-C=TC-HDL−TG×0.16 and Chen (ChenF): LDL-C=non-HDL-cholesterol×0.9−TG×...

Introduction: Thyrotoxicosis after total thyroidectomy (TT) is mostly iatrogenic. Rarely, an hyperfunctional thyroid remnant or ectopic tissue may be the cause. We report a case of Graves’s disease in a mediastinal thyroid mass presenting 7 years after TT for nontoxic goitre.Case report: A 67-year-old woman presented with palpitations, fatigue and weight loss. She had a history of TT for nontoxic multinodular goitre at the age of 60 without any sign...

Introduction: Congenital hyperinsulinism (CHI) typically presents in the neonate, however a minority of cases (~ 35%) present later in infancy and childhood. We report the challenging case of an older infant presenting with hypoglycaemia, diagnosed with CHI and managed entirely within a secondary care setting.Case report: A 9-month-old macrosomic (99th centile) infant presented to the Children’s Emergency Department with hypoglycaemia and a 1 week h...

Aim: serum cortisol dynamic after transsphenoidal pituitary surgery (TSS) in predicting remission and recurrence of CD.Methods: A cohort of 103 CD patients from a referral center was prospectively analyzed at 111 TSS in 6.0±4.8 years of follow-up. Twenty patients received glucocorticoids in transoperative and had serum cortisol measured at 10–12 days after TSS (Protocol I). Eighty six patients had serum cortisol measured at each 6 h in the firs...
