Background: A total of 456 skeletal dysplasias have been classified by molecular, biochemical and/or radiological criteria, into 40 groups. Despite this, the precise, final diagnosis is often difficult due to the high phenotypic and genotypic variability.Objective: To improve the molecular and clinical diagnosis of skeletal dysplasias using a custom-designed next-generation sequencing (NGS) panel.Method: A total of 56 skeletal dysp...

Background: Homozygous aggrecan (ACAN) mutations have been described in a few skeletal dysplasias whilst more recently, heterozygous ACAN mutations have been reported in few families presenting with idiopathic short stature with advanced bone maturation and premature growth cessation.Case presentation: We describe two novel heterozygous ACAN stop mutations, detected using a skeletal dysplasia NGS panel and confirmed by Sanger sequencing...

Introduction: During last years there is an increasing number of referrals because of gender incongruence worldwide. In Argentina, in 2012, a gender identity law was sanctioned, stablishing the right of gender reassignment during childhood, adolescence, youth and adulthood, without the need of previous medical and/or mental health evaluation. This was followed by a great number of referrals. There is scarce literature regarding longterm outcome in transgender persons who start...

Introduction: Turner syndrome (TS) is one of the most common chromosomic disorders characterized by partial or complete lack of one of X chromosomes. It presents variable phenotypic spectrum. Isochromosome of long arm (iXq10) is the third most frequent karyotype and could be in mosaicism in 10-15% of TS. The phenotypic manifestation are similar than girls 45X. It is described a higher incidence of thyroid autoimmunity (even though is currently under discussion) and of diabetes...

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 ...

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...

We report the case of a seven-year-old boy, unicogenised child, born at 33w, PN 1,540 Kg, (APGAR 8-10), hospitalized in neonatology unit for 30 days, invasive respiratory assistance was not necessary. At birth evidence of hypospadias with penile incurvation, oval fossa pervia, corpus callosum agenesis. Normal male karyotype. For positivity to screening for IC (in-situ normal thyroid), started L-Thyroxine therapy. When he was six the phenotype showed broad forehead, down-slant...

We report a case of a 10-year-old girl born at 41st week and spontaneous birth, in therapy with analogous GnRH for idiopathic central puberty. At 4 years bilateral thelarche, performed first and second level investigations and recives diagnosis of early idiopathic central puberty. Since then, therapy with triptorelin 3.75 mg i.m every 21 days was administrated. Regular checks, good compliance, and response to therapy. At 10 years old recurring episodes of headache and vertigo....

Introduction: Primary hypothyroidism is the most frequent thyroid disease in children, and elevation of serum TSH is a common presenting complaint (pc) in the pediatric endocrinology outpatient clinic. Subclinical hypothyroidism (sHT) predominates in relation to overt hypothyroidism (cHT). The benefit of Levothyroxine is controversial specially when serum TSH levels are less than 10 uUI/ml.Objectives: To evaluate the pre...

Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...
