Comorbidities in Turner Syndrome patients controlled in our center since the 80’s

Corripio Raquel , Vargas Laura , Baena Neus , Garcia Emma , Perez Jacobo , Rivera Josefa ,

Introduction: Turner syndrome (TS) is a genetic condition with different phenotypic expressions depending on karyotype. Due to genetic prenatal testing, its prevalence is getting lower. The objective was to analyze the presence of different comorbidities associated with TS according to the karyotype and evaluate if there is follow-up in adulthood.Methods: Descriptive retrospective study including all the patients genetic...

Introduction: The dichotomous nature of the definition of Metabolic Syndrome (MS) in both children and adults can under-diagnose subjects at risk and prevents adequate follow-up of therapeutic interventions. Recently, a continuous score of MS (sSMp) was validated in the pediatric population based on the IDF criteria for a population> 16 years.Objectives: To apply sSMp in a Chilean pediatric population cohort and corr...

Quality of Life in Chilean Transgender Children, Adolescents, and Their Parents

Mendoza Carolina , Martínez-Aguayo Alejandro , Flores Mónica , Morales Cristobal

Background: Quality of life (QOL) includes physical, psychological and social aspects. Transgender (TG) children undergo problems in school and with family, friends, and social relationships. These adverse effects on physical and psychosocial health can impair their quality of life.Objective and Methods: This study aims to assess health-related quality of life (HRQOL), using the KIDSCREEN-52 questionnaire (Spanish versio...

A Deletion Encompassing Exon 2 of the ALS Gene: Analysis of a Patient with ALS Deficiency and His Family

Poggi Helena , Arancibia Monica , Benavides Felipe , Lagos Carlos , Vecchiola Andrea , Dominguez-Menendez Gonzalo , Martinez-Aguayo Alejandro

The main role of the acid-labile subunit (ALS) is to stabilize the IGFBP3/IGF complexes. Pathogenic variants in the gene coding for ALS (IGFALS) results in IGF1 and IGFBP3 deficiency, short stature, delay puberty and insulin resistance. The aim of these study was to identify the genetic cause in a patient with suspected ALS deficiency. The proband is the third son of non-consanguineous parents, evaluated for the first time at 17.3 years due to short stature (−2....

Ovarian Leydig Cell Tumor in an 8 Years Old Girl Misdiagnosed as Congenital Adrenal Hyperplasia Due to Elevated 17-Hydroxi-Progesterone

Arancibia Monica , Garcia-Fernandez Hernan , Martinez-Aguayo Alejandro , Baquedano Paulina , Poggi Helena , Garcia Hernan

Introduction: Non-classical congenital adrenal hyperplasia is the most common pathological cause of early pubarche in prepubertal patients. However, this may also be the first manifestation of central precocious puberty or an androgen producing suprarrenal or ovarian tumor.Objective: To present a clinical case initially misdiagnosed as Congenital Adrenal Hyperplasia that turned out to be an Ovarian Tumor of Leydig Cells.Clinical ca...

A Contextual Feature-Based Recognition Approach to Quantify Trabecular Microstructure Using 1.5T Axial-MRI: An Innovative Methodology

Dimitri Paul , Lekadir Karim , Hoogendoorn Corne , Armitage Paul , Whitby Elspeth , King David , Eastell Richard , Frangi Alejandro

Background: In-vivo skeletal MRI imaging remains challenging due to the extremely short MR relaxation times (<1 ms) of protons bound to water in bone. However, each MRI sequence contains properties identifiable through feature-based recognition, highlighting characteristics relating to skeletal configuration. We thus present a novel statistical method for clinical 1.5 Tesla (T) MRI in quantifying trabecular microstructure and use HRpQCT to determine its accuracy.<...

Primary hyperparathyroidism due to a deletion of the CDC73 gene.

de Beldjenna Liliana Mejia , Garcia Castano Alejandro , Gomez Conde Sara , Castano Luis ,

Introduction: Primary hyperparathyroidism (PHPT), often caused by a single adenoma (80%–85%) or hyperplasia or adenomas involving multiple glands, is the major cause of hypercalcemia. PHPT is common and occurs in individuals of all ages, but its prevalence is lower in young adults. Parathyroid tumors and PHPT can be caused by germline (hereditary PHPT) or somatic mutations of tumor suppressor genes (e.g., multiple endocrine neoplasia type 1 and CDC73) and...

PAPP-A2 Deficiency Induces Sex-Specific Changes in Hydroxyapatite-(CaOH) Crystallinity and the Effects of IGF-1 on Bone Composition in Adult Mice

Vargas Antonio , Rubio Leticia , Rivera Patricia , Christians Julian , de Fonseca Fernando Rodríguez , Chowen Julie , Suárez Juan , Argente Jesús

Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a regulator of IGF-1 availability, causes postnatal growth failure in humans and mice, at least in part through dysregulation of bone size and density. The present study aimed to determine the effects of Pappa2 gene deletion and the response to recombinant murine IGF-1 (rmIGF-1) on femur microstructure and composition. Hydroxyapatite-related crystallography and ionic substitutions were analyzed by X-ray p...

PAPP-A2 Deficiency Results in Sex-Dependent Modifications in Hypothalamic Regulation of Energy Homeostasis

Rivera Patricia , Vargas Antonio , Bonsón Javier , Christians Julian , Rodríguez de Fonseca Fernando , Chowen Julie , Suárez Juan , Argente Jesús

Pregnancy associated plasma protein (PAPP)-A2 is an insulin-like growth factor (IGF) binding protein (BP) protease that regulates IGF-1 availability affecting postnatal growth. Mutations in human PAPP-A2 cause short stature and changes in bone size and mineral density. The present study aimed to characterize the effects of constitutive Pappa2 gene deletion on hypothalamic regulation of energy homeostasis in adult male and female mice. In addition to being sho...

Leptin is Associated with Serum Aldosterone in Paediatric Subjects, Independently of Body Mass Index, Blood Pressure and Plasma Renin Activity

Background: Leptin is considered to play an important role in the development of hypertension in obesity. The excessive synthesis of aldosterone contributes to the development and progression of metabolic and cardiovascular dysfunctions. Leptin is a newly described regulator of aldosterone synthesis that acts directly on adrenal glomerulosa cells to increase CYP11B2 expression and enhance aldosterone production in human adrenal cells lines and in animal models.<p class="ab...
