Differences of sex development (DSD) occur in about 1 in 3000 newborns in Switzerland. The indication and timing of genitoplasty in children with DSDs is a complex issue. In 2012 the Swiss National Advisory Commission on Biomedical Ethics published its position against early irreversible interventions in order to "normalize" the aspect of the external genitalia.We report the case of a child with a 46,XX DSD due to a classical form of congenital a...

Background: Premature adrenarche (PA) has been considered a benign condition. Recently, associations with an increased metabolic risk have arisen. This risk may depend on ethnic background and infancy weight gain, which could be different by gender.Objective and hypotheses: To determine whether PA in children at pubertal onset (TII) determines a higher metabolic profile.Methods: 1190 children (49.9% female) from the longitudinal co...

A new condition, unique to Irish Travellers, was first described clinically as autosomal recessive natural killer and glucocorticoid deficiency (AR-NKGCD) ORPHA:75391 in 2008 and was attributed to recessive founder variant in MCM4/PRKDC gene in 2012. Irish Travellers are an indigenous endogamous population numbering ~40,000 in the Republic of Ireland. AR-NKGCD is characterised by short stature, glucocorticoid and natural killer cell deficiency and is a disorder of DNA repair. ...

Background: IGF1 resistance syndrome (IGF1RS) is characterized by intrauterine and postnatal growth deficit with normal or supranormal IGF1 levels. Additional features may include intellectual deficit, microcephaly, and dysmorphisms. IGF1RS may be caused by genomic or genetic defects affecting the IGF1R locus (15q26.3).Objective and hypotheses: Case report: a girl born at 36.5 weeks, BW 1.935 g (−3.2 SDS), length 41 cm (−4.4 SDS) and...

Objective: To study the impact of dual therapy on BMD and Inhibin B in a group of transsexual male adolescents who initiate treatment with advanced pubertal development.Patients and methodology: Retrospective study of 16 male minors who initiated treatment (Triptorelin and later Testosterone) with complete pubertal development. Variables included: age, weight and height at baseline and at the last visit (calculated in SDS for assigned age and sex), BMD i...

Introduction: Neonatal diabetes, defined as the onset of diabetes within the first six months of life, is very rare disease. Several genetic factors caused to neonatal disease have been identified to date. PTF1A (pancreatic transcription factor 1a) play a key role in early pancreas development and cerebellar neurogenesis. Biallelic mutations in PTF1A have been reported in patients with pancreatic and cerebellar agenesis, whereas mutations loc...

Introduction: Testicular regression syndrome (TRS) is a rare disease characterized by testicular dysfunction that causes varying degrees of virilization defect according to the emergence period in fetal life. The majority of cases present with normal male external genitalia. However, ambigious genitalia or, more rarely, female external genitalia can be found depending on the extent and timing of the intrauterine accident. Here, we present a case of TRS with no...

Background: Medulloblastoma is the most common malignant pediatric brain tumor. Although survival has improved with oncological therapy, late effects such as endocrine consequences are common, especially growth failure and thyroid dysfunction.Methods: Children diagnosed with medulloblastoma in a pediatric hospital between 2004 and 2014 were studied and followed until 2019. Statistical analysis was performed to estimate t...

Introduction: 17 β-Hydroxysteroid Dehydrogenase Type 3 (17β-HSD3) enzyme provides the conversion of ∆4-Androstenedione (A) to testosterone (T) in testicles. 17β-HSD3 deficiency is a rare autosomal recessive cause of 46,XY disorders of sexual development (DSD) and is the most common form of testosterone biosynthesis defects. The external genitalia can vary from normal female appearance to atypical genitalia.C...

Recently, pathogenic biallelic variants in the gene encoding DNA polymerase epsilon catalytic subunit 1 (POLE1), have been described in 15 individuals from 12 families, including members of 3 Irish families. These loss-of-function mutations cause POLε deficiency, thus impairing DNA replication. All reported cases share the same heterozygous intronic variant (c.1686þ32C>G) as part of a common haplotype, in addition to a different loss-of-function variant in the ot...
