Bilateral cryptorchidism: should be systematically explored?

Bergougnoux Anne , Tessier Benoit , Gaspari Laura , Servant Nadege , Cazals Aurelie , Pierre Guibal Marie , Kalfa Nicolas , Paris Françoise

Background: Currently, 1-4% of newborns have cryptorchidism and 30% of them have bilateral cryptorchidism (BC). BC should rule out 46, XX Disorder of Sexual Development (DSD). In 46, XY patients gonosomal abnormalities, alterations in genes involved in 46, XY DSD or hypogonadotropic hypogonadism may be the cause. Currently, patients with BC undergo early orchiopexy in the first 18 months of life. However, in these patients, BC etiology, pubertal development an...

Characterization of the Adipose Progenitor Cell Marker MSCA1 in Normal Weight and Obese Children

Hanschkow Martha , Bouloumié Anne , Dietrich Arne , Kiess Wieland , Körner Antje , Landgraf Kathrin

Background: Obesity is characterized by an increase in fat mass caused by an increase in adipocyte number and adipocyte size and is often associated with adipose tissue (AT) dysfunction contributing to metabolic impairment. It is suspected that adipocyte progenitor cells play an important role during healthy and obesity-related AT expansion. Studies in adults showed that the stroma vascular fraction (SVF) of AT is composed of different progenitor cell subpopul...

Quality of Life and Anxiety in Adolescents with Differentiated Thyroid Cancer

Benoit Melissa Anne

Background: Clinical observations of children and adolescents with differentiated thyroid cancer (DTC) patients led us to investigate quality of life and anxiety. Although adult DTC survivors have similar or slightly worse quality of life (QOL), this has not been evaluated in the pediatric population.Objective and Hypotheses: In this cross-sectional pilot study, our objective was to compare QOL and anxiety in adolescents with DTC to patients with acquire...

CG at the Methylation IGF1 Locus is an Epigenetic Predictor of GH Sensitivity

Ouni Myriam , Castell Anne Laure , Bougneres Pierre

Background: The growth and IGF1 responses to GH treatment show a large variation across children with idiopathic short stature (ISS). Compliance and GH regimens are important determinants. The d3 variant of the GH receptor (GHR) is a significant genetic predictor. The role of individual epigenetics had not been studied. The IGF1 locus is an attractive candidate where CG methylation could influence GH action.Objectives: To study GH effects on a) IGF1 gene...

Meta-analysis of Children with Multiple Endocrine Neoplasia (MEN) Type 2A from 1995-2014: Impact of RET Mutation Screening on Age at Thyroidectomy and Frequency of Metastatic Disease

Burckhardt Marie-Anne , Zumsteg Urs , Szinnai Gabor

Background: Medullary thyroid cancer (MTC) in MEN 2A is caused by mutations in RET. Guidelines (2001/2009/2015) recommend prophylactic total thyroidectomy (TT) based on mutation specific risk levels (ATA 2015: high/moderate).Objective: The aim of this study was to analyse changes of age at TT, frequency of metastatic MTC (MMTC), and frequency of TT according to guidelines since introduction of RET testing in 1995....

A Rare Cause of Short Stature: the Floating Harbor Syndrome

Kayemba-Kay's Simon , Maillet Odile , Heron Anne

Background: Short stature has several causes ranging from complex hormonal deficiencies mostly related to pituitary gland genetics, to idiopathic and environmental causes such as maternal smoking in pregnancy, etc. Floating harbor syndrome is a rare genetic disorder characterized by short stature, delayed bone age, mild to moderate mental retardation, retarded speech development, and typical facial dysmorphic features. The syndrome is caused by heterozygous mutations in exon 3...

Thyroid disorders in childhood cancer survivors treated with 131 I-MIBG, TKIs or immune checkpoint inhibitors: incidence, mechanisms and clinical management – systematic review

Allaert Sarah , Rochtus Anne , Decallonne Brigitte

Background: The thyroid gland is a common unintended target during and after cancer treatment in childhood cancer survivors. However, only a limited number of studies have assessed thyroid adverse events of newer or more selective anticancer drugs. The main objectives of this review are to provide an overview of thyroid disorders in children, treated with 131 I-metaiodobenzylguanidine (131 I-MIBG), tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibi...

A Case of Kearns-Sayer Syndrome Presenting with Hypoglycaemia and Adrenal Insufficiency

Paul Sandipan , Anne Jones Stephanie , Louca Christina

Background: Hypoglycaemia is a common critical condition in paediatric emergencies, with diverse aetiologies including metabolic disorders and endocrine dysfunctions. Adrenal insufficiency is a life-threatening cause, that requires prompt diagnosis and intervention. This case study presents a rare incidence of hypoglycaemia secondary to adrenal failure in a paediatric patient with Kearns-Sayre Syndrome (KSS), a mitochondrial disorder affecting multiple systems...

Parental decision-making after receiving a prenatal diagnosis of Turner syndrome: A qualitative interview study

Dorf Inger , Lou Stina , Skakkebæk Anne

Background and study setting: Turner syndrome (TS) is characterized by either a complete or partial loss of one X-chromosome, resulting in the 45,X karyotype or variants hereof. In Denmark, around 42% of TS foetuses are prenatally detected, most commonly during the first trimester screening, which is offered to all women as part of the free prenatal care. Of these, 69% are terminated. Prior studies have identified several factors influencing parental decision ...

Pituitary tuberculosis and hypothalamic obesity can be reversed by prolonged anti-tuberculosis treatment

Rochtus Anne , Lagae Lieven , Vermeulen Francois , de Zegher Francis

Background and methods: Sellar and suprasellar tuberculomas are extremely rare in children and most often patients present with headache, vomiting, visual disturbances, and hypofunction of the pituitary gland. Here, we report a girl with hypothalamic obesity, that recovers after antituberculosis treatment.Findings: An 11-year old girl presented with headache, fever and anorexia that progressively evolved into an encephal...
