The clinical burden and healthcare resource utilization among children and adolescents with osteogenesis imperfecta: an observational study using Optum’s de-identified Clinformatics® Data Mart Database

Abraham Pranav , Miles Gandarvaka , Petruski-Ivleva Natalia , Hawaldar Kalyani , I. Berger Kenneth

Objectives: Osteogenesis imperfecta (OI) is a skeletal dysplasia affecting 1–2 individuals per 20,000 live births, but the burden of disease in children and adolescents remains unclear. We assessed the clinical and healthcare resource utilization (HCRU) burden of OI in US clinical practice.Methods: This retrospective cohort study included children and adolescents (aged ≤19 years) with OI (≥1 inpatient claim, ...

Novel Genes Identified in Male and Female Sex Development

McElreavey Kenneth

Next generation sequencing technologies are dramatically changing biomedical research and patient diagnosis. The reducing costs of sequencing as well as robust experimental and computational protocols mean that the technology is readily available to most research and diagnostic laboratories. However, the identification of disease-causing mutations in individuals with disorders of sex development (DSD) is challenging for several reasons. These conditions are very difficult to s...

Introduction: Congenital adrenal hyperplasia (CAH) is the most common genetic condition in the spectrum of differences of sex development (DSD). Surgery in DSD is a controversial topic and there is no consensus if to perform surgery, how to perform surgery, and when to perform surgery. The current study was designed to evaluate the current practice in CAH related surgical practice in girls.Patients and Methods: All cases...

Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...

Introduction: Gonadectomy may be indicated in people with differences or disorders of sex development (DSD). Based on historical data from the International-DSD (I-DSD) Registry that showed considerable practice variation, this I-DSD care quality improvement project seeks to determine, through prospective surveillance, the frequency of gonadectomy in individuals with DSD internationally.Methods: All existing I-DSD centre...

Type 1 Diabetes Associated Serum Insulin-Like Growth Factor I (IGF-I) Reference Values in Children and Adolescents

Oberg Daniel , Salemyr Jenny , Ortqvist Eva , Juul Anders , Bang Peter

Background: The disturbance of the GH-IGF-axis in type 1 diabetes (T1DM) with low circulating IGF-I, GH hypersecretion, and hyperinsulinemia, which may be associated with high tissue IGF-I, have implications on long-term vascular complications.Objective and hypotheses: To establish disease, sex and age related serum IGF-I reference values for children with T1DM and test the hypothesis that IGF-I SDS is lower in T1DM than in healthy controls and negativel...

How Do I Diagnose Growth Hormone Insensitivity

Walenkamp Marie-Jose

Classical growth hormone insensitivity (GHI) is caused by a defect of the growth hormone receptor and is characterized by severe postnatal growth failure, craniofacial disproportion, IGF-I deficiency and normal or elevated levels of growth hormone. This is a rare condition. With the development of new genetic techniques during the last two decades other monogenetic defects resulting in milder forms of GHI have been identified. These include genes involved in the GH-IGF-I axis:...
