Liquid chromatography associated with tandem mass spectrometry (LC-MS/MS) is currently considered the gold standard for steroid measurement. The aim of this study was to compare traditional immunoassay and LC-MS/MS methods for androgens measurement before and after human recombinant chorionic gonadotrophin (hrCG) stimulation in children with diagnosis of disorder of sex development (DSD) with 46,XY karyotype and past of normal testosterone secretion. We evaluated 19 patients, ...

Congenital Hypothyroidism Screening Program: the Costa Rican Experience

Bogarin Roberto

Background: The term congenital hypothyroidism was introduced more than 60 years ago when Radwin et al. first described children with hypothyroid-associated features of severe intellectual disability and growth retardation. It is the most common endocrine congenital disorder and preventable cause of mental retardation. Newborn screening programs are an efficient tool for the secondary prevention of mental retardation associated with untreated congenital hypothyroidism...

Description of Patients Diagnosed with Central Diabetes Insipidus, 14 Year Experience at the National Children’s Hospital, Costa Rica

Cavallo-Aita Fred , Montenegro-Villalobos Jiulliana

Background: Diabetes insipidus is a heterogeneous clinical syndrome involving an alteration in water balance. When caused by a deficiency in the production of antidiuretic hormone (ADH) it’s called central diabetes insipidus (CDI). It is difficult to establish the cause of CDI in a good proportion of patients and thus classified as idiopathic in 10.4–55.2%, according to various studies. There are no previous studies in our population.Objective ...

Management and outcomes of congenital hyperinsulinism in infants and young children: a 5-year-experience from the tertiary referral hospital in Indonesia

Fadiana Ghaisani , Soesanti Frida , B Pulungan Aman , Tridjaja Bambang , RL Batubara Jose

Background: Congenital hyperinsulinism (CHI) is a rare condition that becomes the most frequent cause of severe and persistent hypoglycemia in infants and young children. It may lead to debilitating morbidity and mortality if being diagnosed lately. Congenital hyperinsulinism can be caused by monogenic or syndromic disorders. The prevalence of CHI in Indonesia is still unknown. However, the increasing number of cases referred to the tertiary hospital recently ...

Vazquez Veronica Maria Padin , Costa David Albino Gomez , Garcia Aida Del Campo , Cordo Lourdes Rey , Martin Jose Luis Chamorro , Lorenzo Jose Ramon Fernandez

Introduction: Short stature is defined as stature less than −2 standars deviations (SD) for a person’s age and sex of the reference population. Short for gestational age children (SGA) represent 20% of all children with short stature. 10% of these can not catch-up and remains their height below −2 SD. Growth hormone (GH) treatment is a recognized therapy for SGA children authorized in Europe at 4 years old. There are studies that support that younger children ...

Darrigo Emiliana , Sader Soraya , Siena Thais , Nogueira-Barbosa Marcelo , Elias Jr. Jorge , Custodio Rodrigo , Ferraz Ivan , Liberatore Jr. Raphael , Del Ciampo Luiz , Jose Albuquerque de Paula Francisco , Martinelli Jr Carlos

Background: Body weight has a close correlation with bone mass in humans and high fracture rates has been reported in both obese and underweighted individuals. It is not clear the role of bone marrow adiposity (BMA) and the IGF system in this process.Aim: The aim of this study was to analyze bone composition and BMA in obese and non-obese children/adolescents and correlate them with the expression of the IGF type-1 receptor (IGF1R) in peripheral lymphocy...

Weight Gain in Turner Syndrome: Association to Puberty Induction?

Reinehr Thomas , Lindberg Anders , Toschke Christina , Cara Jose , Chrysis Dionisios , Camacho-Hubner Cecila

Background: We have recently reported a BMI-SDS increase in girls with Turner syndrome (TS) treated with growth hormone (GH) (1).Objective and hypothesis: We hypothesise that puberty induction in TS is associated with weight gain.Method: We analysed the weight changes (BMI-SDS) of 888 girls with TS in the Pfizer International Growth Database (KIGS). Overweight was defined by a BMI >90th percentile and obesity by a BMI >97th...

Background: overexpression of the oncogene Yes-associated protein 1 (YAP1), a Hippo pathway target, associates with increased cell proliferation in some human cancers. There is not data on adrenocortical tumors (ACT). YAP1 is a potential target of Wnt/β-catenin pathway, which plays an important role in ACTs.Objective and hypotheses: to evaluate the role of YAP1 and its interaction with the Wnt/β-catenin pathway in ACT.Met...

Bone Mass and Vitamin D Status in Children and Adolescents with Generalized Epidermolysis Bullosa

Claudio Castro Luiz , Nobrega Yanna , Gandolfi Lenora , Pratesi Riccardo

Background: Inherited epidermolysis bullosa (EB) comprises a cluster of genetic disorders characterized by blistering of skin and mucosae following minimal mechanical traumas. Severely affected individuals have high risk of extracutaneous complications, including chronic undernourishment and low bone mass.Objective and hypotheses: The aims of this study were to assess the areal bone mineral density (aBMD) and vitamin D status of children and adolescents ...

Background: 46,XY gonadal dysgenesis (GD) is a spectrum disorder which lead to variable degrees of atypical external genitalia, ranging from female to micropenis and absent of gonadal tissue (known as Embryonic Testicular Regression Syndrome -ETRS). Most patients with 46,XY GD remains without a molecular diagnosis.Objective: To report the DEAH-box helicase 37 gene (DHX37) as a novel candidate for the GD etiology.Patients a...
