Introduction: Prolactinomas are the most common pituitary adenomas in paediatric patients, except in the first decade of life, when ACTH secreting adenomas are more frequent.Objective: Analysis of clinical, diagnostic and therapeutic data of prolactinomas in paediatric age.Methods: Retrospective study of 15 patients whose symptoms began before 18 years of age.Results: In girls, secondary amenorrhea (58.3%) an...

Introduction: Bilateral macronodular adrenal hyperplasia is a rare cause of Cushing’s syndrome (CS) characterized by multiple adrenal nodules >1 cm. It can be diagnosed in patients with overt CS but is more often diagnosed incidentally, especially in the 5th or 6th decades of life.Clinical case: 61-year-old woman with type 2 diabetes, arterial hypertension and dyslipidemia treated with metformin+sitagliptin 1000/50 mg bid, valsartan+hydrochlorot...

Background: Pregnant women with gestational diabetes (GD) have a higher risk of perinatal complication compared to women without. Nevertheless, in women with GD, predictors of perinatal complication are not well established. We aimed to compare, in women with GD, those with and without perinatal complications and to study predictors of perinatal complications in women with GD.Methods: Retrospective study of pregnant women followed in the Endocrinology cl...

Introduction: Subacute thyroiditis is usually a self-limited pathology, possibly of viral aetiology, defined by cervical pain and sometimes systemic symptoms. Its association with autoimmune diseases doesn’t seem to be more frequent than in the general population.Clinical case: Clinical findings of thyrotoxicosis with 3 weeks of evolution associated with anterior cervical pain and fever up to 38 °C. The patient presented with recurrent mouth so...

IntroductionHypogonadotropic hypogonadism (HH) is a rare disease. When associated with anosmia/hyposmia, it is called Kallmann syndrome (KS). Several mutations in different genes have been implicated in its pathophysiology, the most frequent being ANOS1/KAL1, FGFR1 and GNRHR genes. This heterogenicity can be explained by the increasing detection of more than one pathogenic variant in the genes responsible for causing the disease (oligogenism). The preval...

IntroductionPrimary ovarian insufficiency (POI) occurs in 1% of women between puberty and 40 years old. Despite being idiopathic in 74–90% of the cases, there are other etiologies, such as genetic causes (in up to 16% of cases). Triple-X syndrome (TXS) is a common (estimated incidence of 1/1000 women) but frequently undiagnosed chromosomal abnormality. Most women are phenotypically normal, despite this fact, POI can still develop. We present a case ...

Background: Ectopic ACTH secretion from metastatic acinic cell carcinoma (ACC) of the parotid gland is extremely rare. ACC is an uncommon, typically indolent, salivary gland neoplasm. Herein, we report a case of a high-grade ACC later diagnosed with Cushing’s syndrome (CS).Case presentation: A 60-year-old man presented with a laterocervical mass. Computed tomography (CT) documented a 39×38 mm mass on the parotid gland and homolateral cervical l...

Background and Aim: Bilateral Macronodular Adrenal Hyperplasia (BMAH) is a rare form of adrenal Cushing’s syndrome (CS). The treatment of choice in patients with BMAH and overt CS is bilateral adrenalectomy (B-Adx), which however implies lifelong glucocorticoid and mineralocorticoid replacement therapy. Unilateral adrenalectomy (U-Adx) has been proposed as an alternative to B-Adx, especially in case of clearly asymmetric adrenal size. Our aim was to determine predictive f...

Introduction: D-aspartic acid (D-AA) is involved in the regulation of spermatogenesis by influencing hormonal biosynthesis and secretion, resulting in an increased sperm concentration and progressive motility. Coenzyme Q10 (CoQ10) correlates positively with sperm concentration and motility at high concentrations, and it plays an antioxidant role, improving sperm motility and fertilization rate in ICSI cycles. Finally, low concentrations of zinc (Zn) have been found in azoosper...

The sex hormone 17β-estradiol (E2) exerts its pleiotropic effects through the binding to the ligand-activated transcription factor estrogen receptor alpha (ERa). The E2:ERa complex regulates several physiological processes including cell survival and proliferation through transcriptional (i.e., estrogen responsive element (ERE)-based gene transcription) and non-transcriptional membrane-initiated effects (i.e., activation of signalling cascades).Many...
