Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

GHD diagnosis in neonates and infants is a challenge owing to the fact that GH pharmacological stimulation tests (GHST) are not approved at this age. In a retrospective study, we found that a random GH<6.5 µg/L confirmed GHD diagnosis in neonates with clinical suspicion of GHD with high diagnostic accuracy (1). The accuracy of GH and its surrogates of action have not been set for infants with current standardized immunoassays.Objective</...

Primary Hyperparathyroidism caused by a Mutation of the Vitamin D Receptor Gene

de Beldjenna Liliana Mejia de Beldjenna L

Objective: To present a patient with hypercalcemia caused by a parathyroid adenoma and a deletion of the VDR gene.Case clinic: The case is that of a 13-year-old male who presented with hypercalcemia, muscle weakness, nephrocalcinosis, two pathological fractures and a family history of nephrocalcinosis. Physical examination was unremarkable, except the presence of a fracture of the left femur. Laboratory findings: Total s...

Free Fatty Acids Activate Hypothalamic Astrocytes in a Sexually Dimorphic Manner

Argente-Arizon Pilar , Fuente-Martin Esther , Diaz Francisca , Freire-Regatillo Alejandra , Argente Jesus , Chowen Julie A

Introduction: Obesity is known to associate with chronic systemic inflammation. However, hypothalamic inflammation also occurs in response to high fat diet (HFD)-induced obesity and is proposed to participate in central insulin/leptin resistance and the perpetuation of weight gain and systemic affectation. The weight gain and central responses to HFD differ between males and females. As hypothalamic glial cells are implicated in the central inflammatory response we hypothesize...

Palmitic Acid Could Modify Cognitive and Behavioural Functions Through Sex Specific Activation of Hippocampal Astrocytes

Frago Laura M , Freire-Regatillo Alejandra , Argente-Arizon Pilar , Argente Jesus , Chowen Julie A

Background: Prolonged poor dietary habits can result in hypothalamic inflammation and gliosis with more recent studies suggest that other brain areas may also be affected. Western or high fat diet intake has been associated with increased cognitive impairment and aberrant feeding behavior, with males and females being differentially affected. The hippocampus participates in both of these functions. Saturated free fatty acids can induce astrocyte inflammation and this could pot...

Assessment of clinical pediatric perception of short stature in childhood and challenges to treat with Growth Hormone in Brazil: A exploratory evaluation of a developing country daily practice.

Background: Concerns about a child's growth are one of the most common topics parents express during pediatric visits and are a leading cause for referral to a pediatric endocrinologist. For the general pediatric, when short stature is diagnosed, its clinical management remains a challenge.Objective: The aim of the study was to approach and understand the perception from the general pediatrician about short stature,...

CTLA4 A49G and C60T Genetic Polymorphism in Croatian Children and Young Adults with Autoimmune Thyroid Disease

Putarek Natasa Rojnic , Kusec Vesna , Grubic Zorana , Knezevic-Cuca Jadranka , Ille Jasenka , Stajnkler Biserka , Jaksic Bruna , Dumic Miroslav

Background: Autoimmune thyroid disease (AITD), including autoimmune thyroiditis (AT) and GravesÂ’ disease (GD), is a complex autoimmune disease with a strong genetic component. The cytotoxic product of T-lymphocyte antigen-4 (CTLA4) gene, encoding a negative regulator of the T-lymphocyte immune response, was shown to be associated to AITD.Objective and hypotheses: To investigate the association of A49G and C60T polymorphisms of CTLA4 gene in populati...

Nephrogenic Syndrome of Inappropriate Antidiuresis (NSIAD) Managed with Fluid Restriction and Salt Supplementation

Amato Lisa A , Verge Charles F , Walker Jan L , Neville Kristen A

Background: NSIAD is a rare genetic cause of hyponatremia, due to activating mutations in AVPR2 gene, encoding the Arginine Vasopressin Receptor Type 2, and located on Xq28. Of the fewer than 30 reported cases, most have been managed with fluid restriction and urea.Objective and hypotheses: Illustration of the presentation of a family with this genetic abnormality and approach to management.Method: The clinical, biochemical and gen...

Adiponectin as a Marker of Peripheral Insulin Resistance in Adolescents with Polycystic Ovarian Syndrome (PCOS) and as a Tool to Suspect Insulin Receptor Defects

Freire Analia , Gryngarten Mirta , Ballerini Maria Gabriela , Arcari Andrea , Bengolea Sonia Viviana , Scaglia Paula , Bergada Ignacio , Ropelato Maria Gabriela

Background: Decreased serum adiponectin levels are associated with obesity and peripheral insulin resistance (IR). PCOS is characterized by hyperandrogenism and chronic anovulation and frequently is associated to IR. Some defects of Insulin Receptor have been proposed as mechanisms to explain ovarian hyperandrogenism in PCOS.Objectives: To explore adiponectin levels in adolescents with PCOS and to evaluate if adiponectin would identify potential patients...

Insulin Sensitivity in Girls with Central Precocious Puberty at Diagnosis and at 6 Months of GnRH Analogue Treatment

Arcari Andrea , Freire Analia , Escobar Maria Eugenia , Ballerini Maria Gabriela , Ropelato Maria Gabriela , Bergada Ignacio , Gryngarten Mirta

Background: Puberty is associated with a physiological decline in insulin sensitivity. Overweight and obesity are common among girls with Central Precocious Puberty (CPP). CPP and early menarche have been considered as risk factors for obesity and cardiovascular diseases during adulthood. Besides, concern has been raised by the potential impact of GnRH analogues (GnRH-a) treatment on body weight and metabolic profile.Objective and hypotheses: To evaluate...
