Introduction: According to EAU's guidelines, hypospadias (HS) repair is best performed between 6 and 18 months of age. Little is known about the long-term patient satisfaction or urological outcome following HS surgery.Aims: To examine the psychosexual and urological outcome of young adult men (16-21 years old) born with all forms of non-syndromic HS as compared to healthy controls, as well as patient and parental sa...

Introduction: Limited, small-scale studies have revealed that men with proximal hypospadias (HS) or with other signs of undermasculinisation (i.e. complex HS) are at risk of reduced fertility and/or impaired testicular hormone synthesis. However, the extent of this phenomenon and if milder forms of isolated HS are also affected, remains unclear.Aims: To explore reproductive hormones and semen quality of young men (16-21 ...

Background: Maturity Onset Diabetes of the Young (MODY) is a heterogeneous group of disorders characterized by pancreatic beta-cell dysfunction, and usually referred to monogenic forms of diabetes mellitus to distinguish them from the more common type 1 (T1D) or type 2 diabetes (T2D). Fourteen different MODY genetic subtypes have been identified so far. Making a definite diagnosis is very challenging because of overlapping clinical phenotypes between diabetes subtypes. Neverth...

Background: While many causes of 46,XY disorders of sex development (DSD) have been elucidated, the mechanisms leading to 46,XX testicular or ovotesticular DSD are poorly understood. It has been hypothesized that both conditions may represent a phenotypic spectrum and that they might be caused by (different) mutations in the same genes.Methods: Whole exome sequencing was used to identify the molecular cause in ten unrelated patients with 46,XX (ovo)testi...

Background: Acromesomelic dysplasia Maroteaux type (AMDM) (OMIM 602875) is a rare autosomal recessive skeletal disorder with an approximate prevalence of 1/1,000,000) and characterized by severe dwarfism accompanied by shortness of distal and middle segments of extremities. Mutations in the NPR2 gene which encodes for the natriuretic peptide receptor B (NPR-B) is the underlying genetic cause of this disorder.Objective and hypotheses: Genetic con...

Background: Adolescence is often a period of worse metabolic control and less wellbeing in diabetic children. We studied global (GW) and diabetic-related (DRW) wellbeing in diabetic adolescents and the influence of sex, age, ethnic origin, family composition (single- or two-parent family), family income and metabolic control.Method: 133 (71 girls, 120 autochthonous, 20 treated with CSII, 107 from a two-parent family, 68 from families with a monthly incom...

Background: Extensive and time-consuming hormonal and genetic work-up provides a genetic diagnosis in around 20% of 46,XY cases with ambiguous genitalia. It is currently unclear if such extensive screening might also be indicated in 46,XY newborns with milder undervirilization.Method: All 46,XY neonates and infants (n=32, EMS 2–12) referred to our pediatric endocrine service for atypical male genitalia in the period 2007–2013 were inve...

Background: Despite the fact that pituitary stalk interruption syndrome (PSIS) is a frequent finding in children with combined GH deficiency (CGHD), clinical data are still limited and the growth response to GH treatment has not been evaluated in comparison with CGDH with a normal stalk.Objective and hypotheses: To report the clinical and hormonal findings and evaluate the short term growth response to GH in Belgian children with congenital non-syndromat...

Object and Aim: The quality of metabolism in type 1 diabetes depends on different external factors, e.g. the circumstances of living of a patient. We investigated how far the family status, living situation or own children have influence on metabolic control in patients who were transferred to adult care after long-term care in pediatric diabetology.Patients and Methods: From 1998 until 2019 we annually sent a questionna...

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...
