Background: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare autosomal recessive condition characterized by cortisol deficiency and elevated ACTH secretion, resulting in excess androgen production. This exposure to excess androgens contributes to advanced skeletal maturation and reduced growth in puberty. Data from the I-CAH registry were analyzed to identify growth-related characteristics of children and adolescents with...

Background/Introduction: Whole exome sequencing (WES) revolutionized clinical genetics in patients with differences of sex development (DSD). However, our ability to interpret WES data is limited by our incomplete understanding of the mechanisms involved in DSD. Thus, we created a methodology that scores potential candidates based on single cells transcriptomics of human male gonadal cells and applied it to WES data from a cohort of genetically male (46,XY) DS...

Differences of sex development (DSD) occurs when the development of chromosomal sex, gonadal or internal/external genitalia is atypical. It has an incidence of 1: 1000-4500 live born children. New chromosomal array technologies (SNP-array) can analyze the genome of the individual providing information of copy number variation (CNV) of specific chromosomal regions helping to identified pathogenic variants that could explain the etiology of the DSD. This study aims to analyze th...

Introduction: Lockdown measures following the COVID-19 pandemic are shown to have greatly affected lifestyle behaviours and health-related quality of life (HRQoL) of children. The impact on children with severe obesity has not yet been described. Aim of this study was to investigate the impact of COVID-19 lockdown on eating behaviours, physical activity (PA), screen time, and HRQoL of children (including adolescents) with severe obesity....

Background: Noonan Syndrome (NS) can overlap clinically and biochemically with growth hormone insensitivity [GHI; short stature (SS), low IGF-I and normal/elevated GH levels]. Mutations in multiple genes regulating RAS/MAPK pathway have been identified in NS including LZTR1 variants. Function of LZTR1 is poorly understood and its role in growth retardation is unknown.Objectives: To functionally characte...

Background and Aim: Despite the broad individual variation of pubertal maturation, references traditionally describe growth in relation to just chronological age and not biological age. Hence, growth references for the adolescent period have been of limited usefulness for monitoring individual growth in clinic and for research. Especially for children and adolescents with chronic diseases is there a need to better evaluate if changes in SD-scores just before a...

Aim: The study aimed to assess the development of early diabetic retinopathy (DR), one of the microvascular complications, in patients with isolated type 1 diabetes mellitus (DM) (group 1), type 1 DM with a diagnosis of autoimmune thyroiditis (AT) (group 2), and healthy controls (group 3), which were matched for age, sex, number, and body mass index for comparison.Methods: In this prospective and observational study, gro...

Background: Hypospadias surgery is usually performed during infancy at which time parents act as proxy decision makers. Parental decisional regret, a common phenomenon after hypospadias surgery, may be affected by the process of informed consent where decision making between parents and healthcare provider is shared based on available evidence and individual concerns.Objective: To identify short- and long-term parental c...

Introduction: Children with cancer are at increased risk of endocrine complications, especially children with a brain tumor. One of these late effects includes bone disorders (ranging from low bone mineral density (BMD) to osteoporosis). Children with a suprasellar Low Grade Glioma (LGG) may be especially at risk for bone problems due to exposure to multiple treatment modalities, hypothalamic dysfunction and/or decreased mobility in combination with vision los...

Introduction: CAH is a common clinical condition with treatment and follow-up challenges. As a result, the adult height of the cases is known to be affected. We aimed to assess the growth and pubertal development of CAH patients and the factors that influence final height.Method: Between 1980-2022, 41 patients diagnosed with CAH were observed at our clinic. Only cases that attained the final height were retrospectively a...
