Background: Biochemical ratios of precursor-to-product urinary steroid metabolites have been proposed as surrogate markers of steroidogenic enzyme activity to aid the differential diagnosis of inborn disorders of steroidogenesis. Using ratios rather than total amounts facilitates analysis of single spot urine samples, more convenient than 24-h urine collections for young children. Previous studies examining the utility of these biochemical ratios have been lim...

Background: Patients with congenital adrenal hyperplasia (CAH) might suffer from hyperandrogenism. For diagnosing and treatment monitoring, usually levels of androstenedione (A4) and testosterone (T) are measured in blood. More recently, adrenal-specific 11-oxygenated androgens such as 11- hydroxyandrostenedione (11OHA4), 11-ketoandrostenedione (11KA4), 11-hydroxytestosterone (11OHT), and 11-ketotestosterone (11KT) were introduced as promising biomarkers, but ...

The phenotype in male individuals with a mosaic sex chromosomal abnormality is heterogenous, but ambiguous genitalia, delayed puberty, disturbed spermatogenesis, and short stature are frequently seen. Genetic investigation in boys with idiopathic/isolated short stature usually includes SHOX gene analysis (sequencing and copy number detection by MLPA), genome wide array analysis, and/or whole exome sequencing (WES). In the Netherlands, conventional karyotyping is not part of th...

Background: ROHHADNET syndrome is characterised by rapid onset childhood obesity, hypoventilation, variable hypothalamic-pituitary and autonomic dysfunction, and neuroendocrine tumors in 30–40%. Autoimmunity and paraneoplastic syndrome have been proposed as possible pathophysiological mechanisms, but the exact aetiology remains unclear.Objective and hypotheses: We present the clinical course of ROHHADNET syndrome in a 17-year-old girl, with consecut...

Background: In diabetic athletes, glycogen depletion can contribute to the early development of starvation ketones as is demonstrated by our patient.Case presentation: Our patient, a 15-year-old male triathlete with type 1 diabetes for 5 years was referred to our tertiary center because of suboptimal regulation on continuous subcutaneous insulin infusion (CSII). He frequently awoke with nausea and ketosis, which was initially attributed to failure of ins...

Rationale: Bronchopulmonary dysplasia (BPD) is a common complication after preterm birth that is associated with neurodevelopmental impairment. Neurofilament light chain (NfL) has been identified as a biomarker for neuroaxonal damage in preterm infants, but its relation with BPD has not yet been established. We hypothesized that BPD is associated with increased NfL levels at an early stage, indicative of early neuroaxonal damage....

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...

Background: A Europe-wide training program in Paediatric Endocrinology and Diabetes (PED) was initiated by Professor Leo Van den Brande in 1976. PED was recognised as a subspecialty in 1996 by the European Board of Paediatrics (EBP), which is a section of the Union of European Medical Specialists (UEMS). UEMS aims to ensure high standards for training across Europe and the minimum requirements are set out in the European Training Requirements (ETR). The first ...

This presentation briefly gives an overview of typical gynaecological issues and fertility options of transgender adolescents.Typical gynaecological complaints and treatment options will be addressed: e.g. amenorrhea induction prior to cross-sex hormones, irregular bleeding, dysmenorrhea, vaginal discharge but also the limitations of gynaecological examination in female asssigned adolescents.National and international organizations...

Central hypothyroidism can be best defined as lower than desirable thyroid hormone production and secretion because of insufficient stimulation of a normal thyroid gland by a defective pituitary or hypothalamus, resulting in a too low plasma or serum (free) thyroxine (FT4) concentration accompanied by a more or less normal thyrotropin (TSH) concentration. Central hypothyroidism can occur isolated or as part of multiple pituitary hormone deficiency and can be a congenital or ac...
