Introduction: The outcome of hypospadias is considered to be primarily dependent on the underlying aetiology, its surgical management and the duration of follow-up. However, currently, there is little consensus on what set of parameters are essential and clinically feasible for assessment of outcome.Aim: To facilitate the development of a core outcome set for hypospadias by assessment of the range of outcomes reported in boys undergoing surgery.<p cl...

Background: 17 hydroxylase deficiency is a rare form of congenital adrenal hyperplasia resulting from loss-of-function mutations involving the CYP17 gene. It is characterized by decreased production of glucocorticoids and sex steroids and increased synthesis of mineralocorticoid precursors.Objective and hypotheses: We aimed to identify genetic cause of lack of puberty in a girl and the cause of ambiguous genitalia in her sibling. Fourteen-year-o...

Background: Sexual maturation is closely linked to growth, suggesting common pathways between the reproductive development and the growth hormone/insulin-like growth factor-I (GH/IGF-I) axis. IGF-I bioavailability is regulated by Pregnancy associated plasma protein-A (PAPP-A), Pregnancy associated plasma protein-A2 (PAPP-A2) and Stanniocalcin 2 (STC2). A large genome-wide association study (GWAS) identified PAPP-A, PAPP-A2 and STC2 to represent loci strongly a...

Background: Reduced bone mineral density (BMD) is seen in Turner syndrome (TS) with an increased risk of fractures and osteoporosis. Body composition in TS is characterised by increased body fat (FM) and decreased lean body mass (LBM), even with a normal BMI. Oestrogen replacement therapy for attaining and preserving normal bone mass is necessary in most TS girls. There is a potential role of age-specific estrogen doses, with lower doses used in the early puberty and higher do...

Background: The phosphatase and tensin homolog (PTEN)/phosphatidylinositol-3-kinase (PI3K)/AKT signaling pathway is central for cell cycle control, differentiation, migration, and metabolism. Unrestricted growth of adipose tissue in particular is frequently seen in humans with germline PTEN and mosaic activating PIK3CA mutations, respectively.Objective and hypotheses: We assume that adipocytes from affected tissue show hyperproliferation and modified dif...

Background: Trisomy 21 is associated with an increased susceptibility to respiratory infections.Objective and hypotheses: For a more detailed characterization of the adaptive immune response, we analyzed the cellular and humoral immunity to specific pathogens in blood samples of 40 children with Down’s syndrome in comparison to 51 age-matched controls.Method: We quantitatively analyzed lymphocyte subpopulations using flow cyto...

Background: Insulin degludec/insulin aspart (IDegAsp) is the first soluble co-formulation that combines two insulin analogues.Aims and objectives: To assess the efficacy and safety of IDegAsp administered once-daily (OD) plus meal-time IAsp for remaining meals in controlling glycaemia as assessed by change in HbA1c from baseline in a paediatric population.Methods: A 16-week, 1:1, open-label, parallel group, randomised, t...

Objectives: To present Chung-Jansen Syndrome or CHUJANS by a de novo variant in the pleckstrin homology domain-interacting protein (PHIP) gene and compare the clinical phenotype with previous case reports; ②To provide a novel genetic detection methods with whole-exome sequencing(WES) and whole genome sequencing(WGS) and Sanger sequencing for rare genetic diseases.Patients and methods: Following collecting clinical...

Introduction: McCune Albright Syndrome consists of at least 2 of the following 3 features: (1) polyostotic fibrous dysplasia (PFD), (2) Café au lait macules and (3) autonomous endocrine hyperfunction (eg, gonadotropin-independent precocious puberty). Other endocrine syndromes include hyperthyroidism, acromegaly, and Cushing syndrome.Case: 2 year old girl presented with severe hip pain, inability to walk and progressive deformity of right lower limb....
