Introduction: Androgen secreting neoplasms of the ovary are rare and usually show autonomous secretion. Steroid cell tumors of the ovary represent less than 0.1% of all ovarian tumors and are a subgroup of sex cord-stromal tumors. In most cases, patients present with androgenic clinical features.Case report: A 58-year-old woman complained of rapid onset of androgenic alopecia, excessive hirsutism and clitoromegaly. Endocrine assessment showed high levels...

Introduction: Premature pubarche (PP) is most often related to idiopathic premature adrenarche (IPA). However, it is a diagnosis of exclusion and differential diagnosis must include milder and nonclassic variants of congenital adrenal hyperplasia (CAH).Purpose: To identify clinical predictors of CAH and IPA in children with PP.Materials and methods: A retrospective study was conducted including children seen for PP between 2001 and...

Introduction: The association of fasting glucose (FG) in early pregnancy (EP) with adverse outcomes for the mother and her offspring is well known, although the best cut-offs for diagnosis of Gestational Diabetes (GD) are not consensual.Objetive: Evaluate the impact of FG in EP in the management of pregnant women and obstetric and fetal outcomes.Methods: Retrospective cohort of pregnant women with GD diagnosed before 24 weeks of ge...

Introduction: Due to the growing prevalence of obesity, more women are overweight in early pregnancy, leading to adverse neonatal and obstetric outcomes.Objective: To evaluate the influence of maternal prepregnancy body mass index (BMI) on blood glucose levels at diagnosis of gestational diabetes (GD), obstetric and neonatal outcomes.Methods: Retrospective observational study including women with GD and singleton pregnancy, with fo...

Introduction: The American Diabetes Association guideline states that the long-term use of metformin may be associated with biochemical vitamin B12 (B12) deficiency and periodic measurement should be considered, although isolated serum B12 measurement has low sensitivity and specificity. Homocysteine (Hcy) and methylmalonic acid (MMA) are more sensitive biomarkers, the latter being more specific.Objectives: To estimate B12 deficiency in type 2 diabetics ...

Introduction: X-linked adrenoleukodystrophy (X-ALD) is caused by a mutation in the ABCD1 gene, which encodes for a peroxisomal very long chain fatty acid (VLCFA) transporter. Clinically, X-ALD can present a wide spectrum of phenotypes, being the most frequent Adrenomyeloneuropathy, with ataxia, spastic paraparesis, sexual and sphincter dysfunction. Adrenocortical insufficiency (AI) occurs mainly in paediatric age and it can be the first manifestation of the disease in some cas...

Aim: To define the main predictors of metabolic control in children and adolescents and evaluate its improvement along the years.Methods: We included children and adolescents with 1DM, with more than two years of disease. Data were collected at 2005 and at 2012. Sex, age and severity at diagnosis, therapy in the last year, age at onset of multiple daily insulin injections (MDII) and continuous subcutaneous insulin infusion (CSII), number of group educati...

IntroductionPrimary hyperparathyroidism (PHPT) is a common endocrine disorder and classically associated with hypercalcemia (HHPT). There is a newest variant of PHPT, defined by normal albumin-corrected calcium levels - normocalcemic PHPT (NHPT) – which may represent an early stage of HHPT. Nevertheless, there is limited data on how this variant presents clinically and biochemically.AimTo evaluate the de...

Introduction: Tyrosine kinase inhibitors (TKI) demonstrated clinically significant activity in radio iodine (RAI)-refractory differentiated thyroid cancer (DTC) and in locally recurrent, unresectable and metastatic medullary thyroid cancer (MTC). The natural history of MTC and DCT is quite variable with rates of disease progression ranging from a few months to many years. TKI can be associated with progression-free survival, but is not curative and the side effects may have a ...
