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...

We characterised the phenotype of PHP patients at two UK tertiary care centres and investigated phenotype-genotype correlations.Method: Retrospective review of case notes for patients with PHP at two UK tertiary care centres.Results: 55 patients, from 41 kindreds, were identified; 32 with PHP1a, 23 with PHP1b. The PHP1a cohort (56% female, 69% White), currently aged 16.7+/-10.6 years, presented at ...

Objectives: To describe safety and effectiveness of high (≥90-180 µg/kg) and low (<90-30 µg/kg) dose leuprorelin in treating central precocious puberty (CPP).Methods: In this observational, retrospective study, effectiveness was evaluated based on regression or no progression of Tanner staging as the primary outcomes. LH, FSH, estradiol or testosterone suppression, and decrease in bone age to chronolo...

Introduction: The annual incidence of severe influenza infections reaches 5 million cases globally. Patients with diabetes mellitus (DM) are known to suffer more severe influenza infections, with increased mortality. Despite vaccination being recommended as standard of care, vaccination uptake rates have remained low for our DM patients. We undertook a quality improvement (QI) initiative to improve influenza vaccination uptake rates in our paediatric DM clinic...

Introduction: Our study aimed to describe the clinical profile of children with central precocious puberty (CPP) presenting to a single tertiary centre, and to determine the factors that would lead patients and families to pursue treatment with gonadotrophin releasing hormone (GnRH) agonist as well as the predictors of a more favourable final adult height in this cohort.Methods: We conducted a retrospective medical chart...

Background: Bone growth and mineralization during childhood are now recognized as important for bone health in adulthood, leading to renewed interest in identifying modifiable factors that impact bone mineral density (BMD) in childhood. Emerging data suggest that duration of breastfeeding may affect BMD in later childhood and adult life. However, such data are sparse and inconsistent.Objectives: This study examined the relationship betwe...

Objectives: Abdominal fat has been strongly linked to increased cardiometabolic risk and impaired glucose regulation in adults. Owing to the lack of detailed body composition phenotyping in most previous child cohort studies, the temporal links between abdominal fat accumulation and impaired glucose regulation have not been well established. In this study, we evaluated the associations of abdominal fat assessed by MRI at early infancy (≤21 days after birth) and at 4.5 ye...

Background: Growth patterns in infancy and early childhood have been linked to risks of obesity and cardiometabolic disorders in adulthood. Body fat partitioning, particularly increased fat accumulation at ectopic sites, has been strongly associated with cardiometabolic disorders. However, the lack of precise body composition measures in prior longitudinal birth-cohort studies has made it difficult to ascertain if early growth patterns could result in consolidation of distinct...

Background: Metabolic syndrome and impaired bone health are common complications in childhood cancer survivors, and both are possibly related with decreased physical activities.Objective and hypotheses: We aimed to evaluate the prevalence rates of metabolic syndrome and osteopenia in adolescent/young adult childhood cancer survivors. We also aimed to investigate the relationship between physical activity and these complications.Met...

Background: Congenital adrenal hyperplasia (CAH) arises from mutations in CYP21A2 gene, which encodes for the steroidogenic enzyme 21-hydroxylase. Currently employed chorionic villus sampling and amniocentesis provide genetic results at ~14 weeks of gestation at the earliest. At this time, the genitalia of the affected female foetuses have already become virilized. To prevent genital ambiguity, prenatal treatment with dexamethasone must begin on or before gestational ...
