Background: Gordon Holmes syndrome (GHS) is characterized by cerebellar ataxia/atrophy and normosmic hypogonadotropic hypogonadism (nHH). The underlying pathophysiology of this combined neurodegeneration and nHH remains unknown.Patients and methods: We studied a cohort of multiplex families with GHS through autozygosity mapping and whole exome sequencing.Results: We identified patients from three independent families carrying loss-...

Seasonal 25-hydroxy Vitamin D3 Variations in School-aged Children from Santiago de Chile

Poggi Helena , Dominguez Gonzalo , Monica Arancibia , Moore Rosario , D'Apremont Ivonne , Solari Sandra , Allende Fidel , Sifaqui Sofia , Garcia Hernan , Martinez-Aguayo Alejandro

Introduction: The main role of Vitamin D (VitD) is the regulation of calcium, which is also regulated by the parathyroid hormone (PTH), and phosphate metabolism. The main source of the more biologically active 25-hydroxy-Vitamin D3 (25OHVitD3) comes from the action of ultraviolet light on the skin.Aim: To determine if there are differences in concentrations of 25OHVitD3, calcium and PTH in school-aged children throughout...

Decreased Vitamin D Levels in The Pediatric Population After Covid-19 Lockdown

Pausilli Romina , Gaudino Rossella , Antoniazzi Franco , Cavarzere Paolo

Backgroud: SarsCov2 infection began to spread worldwide since December 2019 and, on March 2020, the World Health Organization characterized its related disease, named COVID-19, as a pandemic. In Italy, to contain the spread of infection a severe lockdown from March 10th, 2020 to May 4th, 2020 was instituted. Other less severe restrictions were imposed in the winter 2020-2021 and in the spring 2021. The containment measures caused a series of consequences for t...

Coincidence of Newly Diagnosed Type 1 Diabetes Mellitus with Enteroviruses and Respiratory Tract Viruses

Karaoglan Murat , Eksi Fahriye , Keskin Mehmet , Karaoglan İlkay

Background: Viruses, which trigger and promote islet cell destruction, cause type 1 diabetes mellitus (T1DM). However, the existence of a cause-and-effect relationship is under debate. The aim of this study was to investigate sero-epidemiological and molecular evidence of enteroviruses and respiratory viruses in patients with newly diagnosed T1DM during cold season.Methods: This study included 40 children with newly diagnosed T1DM and 30 healthy children...

Seasonality of Type 1 Diabetes in Children and Adolescents According to Date of Diagnosis and Date of Birth in a Large Diabetes Centre

Vasilakis Ioannis Anargyros , Kosteria Ioanna , Tzifi Flora , Christopoulos-Timogiannakis Evangelos , Kotrogianni Paraskevi , Chrousos George , Kanaka-Gantenbein Christina

Background: There are studies supporting the seasonality of diabetes according to date of diagnosis and date of birth, with most T1D children being diagnosed in fall and winter and most of them been born in the same period. That is in concordance with previously published data from 1978 to 2008 in our country.Objective and hypotheses: To assess whether there is a seasonal variation of diabetes onset according to date of diagnosis and date of birth of inc...

Congenital hypogonadotropic hypogonadism in a large French cohort : New genetic findings

Talbi Abir , Hypogonadotropic Hypogonadism Study Group , de Roux Nicolas ,

Congenital hypogonadotropic hypogonadism (CHH) is a rare condition caused by a dysfunction of the GnRH Axis. The clinical variability of the disease is accompanied by genetic heterogeneity. Indeed, more than 40 genes are implicated in the pathogenesis of this condition. The main goal of this present study was to characterize genetic defects in a large cohort of French CHH patients using a targeted NGS panel.Patients: a cohort of 120 unrelated patients (7...

Evaluation of Bone Health in Adolescents and Young Adults After Allogeneic Human Stem Cell Transplantation in Childhood: A Single Center Cross-Sectional Study

De Waele Kathleen , Tack Lloyd , Bordon Victoria , Van Lancker Sophie , Dhooge Catharina , Cools Martine

Introduction: Hormonal deficits are well known complications after allogeneic human stem cell transplantation (alloHSCT) in childhood and treated according to existing guidelines. It is assumed that bone mass and strength accrual during puberty is also often impaired, due to toxic therapy and prolonged inactivity, but data on bone geometry and strength are scare in this particular group.Objective/Patients and Methods: Cr...

Vitamin D deficiency in pediatric population and influence on PTH levels

Diez-Lopez Ignacio , Sarasua Miranda Ainhoa , Maeso Mendez Sandra

Transversal study. Patients from 0 to 17 years of age who had undergone an analytical determination of 25OHD during the year 2021 in our hospital were collected. The following were contrasted: 25OHD, PTH, total calcium, age, sex, reason for requesting analysis, time of year and country of origin. 25OHD ranges: normal >30 ng/mL, suboptimal 20-30 ng/mL and deficit <20 ng/mL; and normal PTH: 9-60 pg/mL.Results: 1. Prevalence of vitami...

The challenge of gender identity due to 5α-reductase deficiency- a case report

Herrmann Gloria , Bauer Agnes , Winner Kay , Kapapa Melanie , Stoll Elvira , Serra Alexandre , Wabitsch Martin

The 5α-reductase deficiency type 2 is a rare autosomal recessive 46,XY disorder of sexual development (DSD), presenting with a wide clinical spectrum ranging from a male phenotype with hypospadias to a female phenotype with wolffian structures. Here we report about the clinical, hormonal and molecular characterization of two siblings with a mutation in the SRD5A2 gene, as well as the challenge of gender identity and the importance of psychosocial care. The older sibling ...
