Background: Obesity in Prader-Willi Syndrome has peculiar features associated to reduced lean body mass which could confer different metabolic characteristics.Objective and hypotheses: The aim of this study is to describe and to compare the metabolic profile in obese patients and obese Prader-Willi syndrome patients (OPWS) followed in a Pediatric Endocrinology outpatient clinic.Method: 45 obese and 22 OPWS patients between 8 and 20...

Introduction: De novo and inherited cases of 16p11.2 microdeletion and duplication syndromes have a spectrum of clinical manifestations, with incomplete penetrance and variable expressivity.16p11.2 copy number variants have shared phenotypic features (autism, developmental delay). Mirror phenotypes have also been described: deletions – obesity, hyperphagia, macrocephaly; duplications – underweight, feeding/eating disor...

Introduction: The complications of obesity are well recognised and documented in the adult population. There is little data available that reports the complications of childhood obesity seen in clinical practice. The aim of our study is to investigate the different types of complications seen in children and young people (CYP) with obesity.Methods: 125 CYP aged 0-18 years who had a body mass index (BMI) standard deviatio...

Background: Growth Hormone Insensitivity (GHI) is usually caused by mutations in the Growth Hormone receptor (GHR). Patients present with short stature associated with high GH and low IGF-I levels and often have midfacial hypoplasia (typical Laron syndrome facial features). Our centre previously described the first GHR pseudoexon mutation (42700896A>G, c. 618+792A>G). The inclusion of this 108bp pseudoexon is predicted to lead to in-frame insertion of...

Background: Primary ovarian insufficiency (POI) affects 1% of women and is associated with significant medical consequences. In approximately 10% of cases, POI presents early with absent puberty or primary amenorrhoea. A genetic cause for POI can be found in up to 30% of women. Identified genes often relate to the complex biological processes occurring in fetal life which underpin normal ovary development and function in later adulthood.Objective: We aim...

Background: Hypercalciuria, short stature and low bone mineral density are features of distal renal tubular acidosis (dRTA) and osteogenesis imperfecta (OI). If untreated, the presence of dRTA in patients with OI may worsen the prognosis and lead to poorer height outcomes. We describe two unrelated children with an unusual association between OI and dRTA.Cases: Patient 1 is a 7-year-old female diagnosed prenatally with a COL1A2 mutation and postnatally w...

Background: Hypernatraemia in a neonate can be common, and is usually due to high rates of insensible water loss and high urine output and subsequent dehydration. This is commonly resolved with supplementation of feeds.Case presentation: We present a preterm baby born at 35 weeks gestation who was born in good condition, did not require ventilation or intensive care support. The only support required was for feeding and thermoregulation. In the second we...

Background: Gordon Holmes syndrome (GHS) is characterized by cerebellar ataxia/atrophy and normosmic hypogonadotropic hypogonadism (nHH). The underlying pathophysiology of this combined neurodegeneration and nHH remains unknown.Patients and methods: We studied a cohort of multiplex families with GHS through autozygosity mapping and whole exome sequencing.Results: We identified patients from three independent families carrying loss-...

Background: Socioeconomic deprivation is an important determinant of health.Objectives: This study examined the relationship between incidence of hospital admissions for patients with Type 1 diabetes mellitus (T1DM) and their socioeconomic deprivation.Methods: All hospital admissions of patients with T1DM from 0 to16 years were identified during a 5-year period between 2007 and 2012 using the hospital episodes statistics database (...

Background: Socioeconomic deprivation, obesity and emotional well-being are important determinants of health inequalities and poor glycaemic control in adults with type 1 diabetes mellitus (T1DM).Objectives: This study aims to look at the effect of social deprivation, BMI and patient reported emotional well-being on glycaemic control in children and young adults with T1DM.Methods: Socioeconomic status was measured by cross-referenc...
