Background/Introduction: Whole exome sequencing (WES) revolutionized clinical genetics in patients with differences of sex development (DSD). However, our ability to interpret WES data is limited by our incomplete understanding of the mechanisms involved in DSD. Thus, we created a methodology that scores potential candidates based on single cells transcriptomics of human male gonadal cells and applied it to WES data from a cohort of genetically male (46,XY) DS...

Drosophila melanogaster as a study model has already significantly contributed to the understanding of the mechanisms of many human diseases. So far D. melanogaster has rarely been exploited as a model for human sex development. Nanda et.al already demonstrated in 2009 that the Drosophila orthologue of SOX9, Sox100B is essential for testis development in Drosophila. Similarly, we could demonstrate that the fly homolog of STARD8, cv-c</...

Background: In our bone unit, we were following since their younger age, two brothers with a severe osteogenesis imperfecta. We had no genetic confirmation but the severity of the disease combined with unaffected consanguine parents argues for a recessive autosomal transmission. Both present with highly severe form of osteogenesis imperfecta: repeated vertebral and peripheral fractures, long bone deformations, centromedullary nails on the lower limbs, major motor handicap and ...

Background: Prader-Willi syndrome (PWS) is a rare genetic disorder characterized by hyperphagia and abnormal behaviours towards food for both of which no approved treatment is available. Elevated plasma acylated ghrelin (AG) documented at all ages in PWS suggest that the ghrelin system may contribute to the pathophysiology of hyperphagia. Administration of unacylated ghrelin and 8-amino acid analog AZP-531 prevents AG-induced food consumption in animals and improves glucose co...

Background: Prader–Willi syndrome (PWS) results from abnormalities in the genomic imprinting process leading to hypothalamic dysfunction with an alteration of GH secretion. PWS is associated with early morbid obesity and short stature which can be efficiently improved with GH treatment.Objective and hypotheses: Our aims were to highlight adipose tissue structural and functional impairments in young children with PWS and to study the effect of GH tre...

Background: Early-life risk factors of childhood obesity include maternal obesity; smoking, diabetes and high weight gain during pregnancy for the mother; short duration of breastfeeding and poor quality of early feeding in the infants. Perinatal life thus may be a good period for primary prevention.Objective and hypotheses: We aimed to evaluate whether perinatal education of overweight pregnant women would reduce childhood overweight.<p class="abste...

Background: The SCOPE French retrospective study follows children affected with growth hormone (GH) disorders treated with recombinant human GH (r-hGH) therapy via the easypod® connected injection device for up to 5 years.Aim: To show the results from an interim analysis of the SCOPE study analysing adherence to r-hGH therapy in a real-world setting and its effect on catch-up growth.Met...

The purpose of this study is to determine the frequency of occurrence and molecular-genetic characteristics of MODY in patients with diabetes mellitus aged 1 to 18 years, residents of St. Petersburg.Materials and methods: In St. Petersburg in 2017, there were 1620 patients with diabetes mellitus under the age of 18 years. 54 of them had evidence of hereditary variants of diabetes with chronic hyperglycemia at normal c-peptide indices for 2 years after th...

A structured program of therapeutic education is essential to achieve a good result from the use of technology in the treatment of diabetes.Objectives: Facilitate knowledge, skills and aptitudes to patients and their families in therapy. Promote the capacity for self-management and adherence to treatment. Provide ongoing support to patients. Improve clinical outcomes, health status and quality of life.Metho...

Objectives: -To determine children diagnosed with central congenital hypothyroidism (CCH) by a screening program using TSH and total T4 between May 2016 and January 2019.-To analyze the characteristics of the disease in these children.Material and Methods: During the time of the study, 14.743 newborns have been screened. Cut-off points are used for TSH ≥10MU/ml and T4 6 and 20 mg/dl as lower ...
