Objective: To provide etiology-based diagnostics to pediatric patients with diabetes in Belgium using routine clinical phenotyping and thorough genotyping.Methods: A Belgian GENEPEDIAB study consortium was created to screen, using routine diagnostic tools, for monogenic forms of diabetes in pediatric patients followed in convention centers for type 1 or type 2 diabetes, while presenting atypical biological and clinical f...

Diabetes mellitus is a chronic disease. The risk of microvascular complications is correlated with hemoglobin A1c (HbA1c) level [1] Educating the diabetic patient to keep an HbA1c below 7% reduce the risk of long-term complications. We report the case of a 15 years old teenager, with chronical headache, referred for diabetes mellitus with a fasting glycemia of 83 mg/dl (normal < 100) and an HbA1C of 8.3% using an Ion-exchange High Performance Liquid Chromatography (HPLC, Ad...

Background: Bilateral testicular regression (BTR) is characterized by the absence of both testicles in a newborn male or shortly thereafter, and presenting as bilateral cryptorchidism with undetectable AMH levels and the absence of Müllerian structures on pelvic ultrasound. Depending on when the regression occurs during fetal development, the condition can be associated with a micropenis. Few studies have explored the etiology and long-term outcome of BTR...

Background/ Aim: Over the past 6 years, the IGF1/ IGFBP3 generation test (IGFGT) has been used in Belgium in a standardized form to identify children with severe primary IGF1 deficiency (SPIGFD). In this study, the discordance of the IGF1 and IGFBP3 responses during an IGFGT and the prevalence of SPIGFD were analyzed in a cohort of children with short stature (height SDS < - 2) and presenting with low (below lower reference limit) serum IGF1 level and norma...

Background and Aim: Recombinant growth hormone (GH) is reimbursed for the treatment of short stature (<-2.5 Z-score) in children born small for gestational age (SGA) without postnatal growth, aged ≥ 4 years with a height Z-score >1 below mid-parental height (MPH). We wanted to determine the current GH prescribing practices by pediatric endocrinologists (PE) for SGA related short stature and document the percentages of treated children at risk for...

Background: Long-term outcome studies on bilateral testicular regression (BTR) are currently lacking, hampering counseling of patients and parents. Although a vascular origin was initially reported, recent studies revealed a genetic origin in a subset of patients (i.e. DHX37 gene variants). How this relates to patient outcomes remains unclear.Methods: Thirty-five patients with BTR were recruited in eight Belgian centers ...
