Objective: Recent studies have suggested earlier onset of pubertal development in boys. As assessment with orchidometer tends to overestimate true testicular volume (TV), and measurements based on ultrasound (US) have been proposed as a more reliable method, we present US based references in 6-16 year-old Norwegian boys. Our results are compared with data from Europe and the United States (U.S.) in order to establish evidence for an ongoing secular trend in ma...

Background: Using ultrasound to examine the glandular breast tissue is a promising method for staging pubertal breast development. However, breast ultrasound for this purpose has not been explored in a large sample of healthy girls in different developmental stages, and normative data have been unavailable.Objective: To present novel pubertal references for breast ultrasound stages, Tanner breast (B) and pubic hair (PH) ...

Introduction: Male puberty is initiated by endocrine signaling in the hypothalamic-pituitary axis whereby follicle-stimulating hormone (FSH) and luteinizing hormone (LH) enable testicular maturation and synthesis of testosterone. Recent publications have eluded to overnutrition and obesity as relevant factors that may accelerate the timing of puberty. Attainment of testicular volume (TV) 4 ml measured by Prader orchidometer remains the definition of male puber...

Introduction: Bone Health Index (BHI) determined by measurement of cortical thickness of metacarpalia II-IV in x-rays of the left hand represents a method to estimate bone health in children. Aim of this study was to investigate changes of BHI SDS in the course of growth hormone (GH) treatment.Method: 256 consecutive children with short stature (isolated GH deficiency (IGHD) n = 121, multiple pituitary hormone deficiency...

SOX3 is located on the X-chromosome (Xq27.1) and encodes a SRY-related protein that acts as a developmental transcription factor. Copy Number Variations (losses and gains), mutations of polyalanine stretches (deletions or expansions) and missense mutations of SOX3 have been associated with growth hormone deficiency with incomplete penetrance, hypogonadism, differences of sexual development and variable additional endocrine disorders (MIM #312000 and #300123)....

Background: Childhood obesity and related co-morbidities are increasing world wide and consequently effective treatment interventions are much needed.Objective and hypotheses: The aim was to investigate concomitant changes in body composition in relation to changes in BMI–SDS during The Children’s Obesity Clinics Treatment (TCOCT) program. Hypothesis: reductions in body fat percentage may not be revealed by reductions in BMI–SDS.<p cla...

Background: TV-1106 (Teva Pharmaceuticals Ltd) is a genetically fused recombinant GH (rhGH) and human serum albumin in development as a once weekly treatment of GH deficiency (GHD) in children and adults. TV-1106 has an extended duration of action compared to daily rhGH treatment, reducing the frequency of injections.Objective and hypotheses: The pharmacokinetics and pharmacodynamics of TV-1106 were evaluated in phase 2 study using non-compartmental anal...

Background: Final height in patients with congenital adrenal hyperplasia (CAH) is generally assumed to be lower than the population norm. Besides CAH subtype and age at diagnosis, timing of pubertal development is considered to have a significant impact on final height. In most CAH patients, puberty starts within normal ranges, although at a somewhat earlier mean age compared to reference populations. CAH-complicating gonadotropin-dependent precocious puberty has been reported...

Short stature is diagnosed when height is significantly below the average of the general population for that person’s age and sex. To elucidate the factors that modify disease severity/penetrance in short stature, we have studied a three-generation family with SHOX deficiency. We have found that the retinoic acid degrading enzyme CYP26C1 is a modifier for SHOX deficiency phenotypes towards the more severe clinical manifestations (Leri-Weill dyschondrosteosis) and confirme...

Background: Depending on age, needs and preferences in insulin therapy strongly differ between children and adolescents with type 1 diabetes (T1D).Objective and hypotheses: To analyse trends in insulin regimen and type of insulin used over the last two decades in three age-groups of pediatric patients with T1D from Germany/Austria.Method: 63 967 subjects (<18 year of age) with T1D documented between 1995 and 2014 from the &#145...
