Juanes Matias , Guercio Gabriela , Marino Roxana , Berensztein Esperanza , Ciaccio Marta , Gil Silvia , Rivarola Marco A , Belgorosky Alicia

Background: IGF1R gene mutations have been associated with varying degrees of intrauterine and postnatal growth retardation, and microcephaly. We have previously reported three novel variants in the IGF1R gene: de novo p.Arg1256Ser, de novo p.Asn359Tyr and p.Tyr865Cys (ENDO 2013, OR20-2).Aim: To characterize the functional effects of the novel IGF1R gene allelic variants.Methods: In ...

Is Small for Gestational Age Status Associated with an Increase Risk of Atherogenesis?

Stroescu Ramona , Micle Ioana , Marazan Monica , Marginean Otilia , Bizerea Teofana , Doros Gabriela

Background: The ‘catch-up growth’ phenomenon in children born small for gestational age (SGA) has been linked to early onset obesity with the subsequent emergence of metabolic syndrome (MetS). The intima media thickness of the common carotid artery (CIMT) is a well-known marker of subclinical atherosclerosis.Objective and hypotheses: To determine the association between being born SGA and CIMT, a measure of atherogenesis and to investigate meta...

Background: Aortic dilation (AD) occurs in Turner syndrome (TS) increasing the risk of aortic dissection at all ages. There are no current guidelines on what specific aortic diameter measurement should provoke concern in pediatric TS. Because of their small stature, an aortic size index (ASI) has been proposed to normalize the ascending aorta (AA) to body size in young adults’ with TS. However, a more reliable index has been also proposed: the ratio of vascular diameter t...

Moya Moya Syndrome in a Patient with Growth Hormone Deficiency and Hypergonadotropic Hypogonadism: to Treat or not to Treat with Growth Hormone Therapy?

Briceno Laura Gabriela Gonzalez , Stoupa Athanasia , Pinto Graziella , Touraine Philippe , Polak Michel

Background: Moya Moya disease is a chronic cerebrovascular angiopathy characterized by progressive stenosis of terminal part of internal carotid vessels and the compensatory development of collateral vessels. We present here the case of a young boy with growth hormone deficiency (GHD) and testicular insufficiency that was diagnosed with Moya Moya syndrome.Case presentation: A 12.9 year-old boy of Serbian origin was referred to the Endocrinology Departmen...

Schaaf-Yang syndrome: Report of two cases

Rampi Gabriela , Berger Malena , Cecchi Griselda , Schneider Claudia , Juarez Peñalva Sofia , Forrester Andrea

Schaaf-Yang syndrome (SYS) is a genetic disorder caused by truncating pathogenic variants in the paternal allele of the maternally imprinted, paternally expressed gene MAGEL2, located in the Prader-Willi critical region 15q11-15q13. SYS is a neurodevelopmental disorder that has clinical overlap with Prader-Willi Syndrome in the initial stages of life, being the intellectual disability, developmental delay, autism spectrum disorder, neonatal hypotonia, infantile feeding problem...

Unusual presentation of pheochromocytoma (PCC) and paraganglioma (PGL) in two sisters with von Hippel Lindau disease (VHL)

Vieites Ana , J. Benítez Amanda , Eugenia Rodríguez María , Bignon Horacio , Sansó Gabriela

Introduction: Von Hippel-Lindau disease(VHL) is an autosomal dominantly inherited tumor syndrome that predisposes to development benign and malignant tumors. The prevalence of VHL disease is one in 36,000, and the penetrance is higher than 90%. PCC occur in up to 20% of VHL patients. Classically, it is characterized by having an adrenal location, mostly bilateral and being derived from the sympathetic nervous system, resulting in the releases of catecholamines...

Gutierrez Marcela , Soria Marcela , Morán Lorena , Ferraro Cristina , Bedecarrás Patricia , Drelichman Guillermo , Aversa Luis , Bergadá Ignacio , A. Rey Rodolfo , P. Grinspon Romina

Aim: To determine Sertoli cell function at diagnosis and after 3 months of chemotherapy.Methods: A prospective cohort study was performed including children with acute lymphoblastic leukaemia, acute myeloid leukaemia, or non-Hodgkin lymphoma. Serum levels of AMH were evaluated at diagnosis and after 3 months during chemotherapy. Results were analysed as standard deviation scores according to pubertal stage and expressed ...

Diagnostic Value of Random Serum Growth Hormone (GH), IGF-I and IGFBP-3 Concentrations for the Diagnosis of Growth Hormone Deficiency (GHD) in Patients Below One Year of Life

Ballerini María Gabriela , Braslavsky Débora , Freire Analía Verónica , Keselman Ana , Rodríguez María Eugenia , Altube Mercedes , Scaglia Paula Alejandra , Bergadá Ignacio , Ropelato María Gabriela

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</...

Ovarian AMH production is transiently affected in pubertal and prepubertal girls with acute lymphoblastic leukaemia and non-Hodgkin lymphoma receiving chemotherapy: a prospective, longitudinal study.

Gabriela , Gryngarten Mirta , Soria Marcela , Moran Lorena , Ferraro Cristina , Freire Analia , Bergada Ignacio , Drelichman Guillermo , Aversa Luis , Rey Rodolfo A. , Grinspon Romina P. ,

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...
