Leptin receptor deficiency is a rare genetic disorder that affects the body’s ability to regulate appetite and weight. For patients and their families, the disorder seriously disrupts daily life, however, little is published about this impact. We here report the experiences of a 10.5-year-old girl with leptin receptor deficiency and her family. The diagnosis of this rare genetic obesity had a deep impact on the life of the child and her family. It led to a better underst...

Background: Paediatric obesity is a multifactorial disease characterized by an imbalance between energy intake and expenditure. In rare cases, obesity is caused by underlying medical disorders arising from disruptions in the leptin-melanocortin pathway, which regulates satiety and energy expenditure.Aim: To investigate resting energy expenditure (REE) in relation to body composition in children and adolescents with sever...

Introduction: In rare cases of obesity, genetic defects lead to hyperphagia and severe early-onset obesity. Genetic testing in patients with a suspected genetic obesity phenotype is important, as it can lead to patient-tailored treatment advice. For children, the Endocrine Society (ES) recommends genetic testing in children with early-onset of obesity (<5 years) and hyperphagia. It is unclear whether these recommendations can also be used in adult obesity c...

A female child born from non consanguineous parents of Pakistani origin presented with congenital heart anomaly at prenatal ultrasound and confirmed at birth, with type B aortic arch interruption, right-sided aortic arch, wide ventricular and atrium septum defects, which required repeated surgical corrections during the first 9 months of life. The ultrasound also reported absence of the thymus. Suspecting Di Deorge Syndrome, a fluorescent in situ hybridization (FISH) ...

Background and aims: The spread of obesity among children and adolescents is increasing significantly in the last decades. The World Health Organisation defined the disease as a global epidemic and the need of complex interventions worldwide is well recognised. Obesity is major risk factor for many chronic diseases, including diabetes, cardiovascular and lung diseases, orthopaedic and skin problems, and cancer. There are strong predictors that 50% of pre-pubertal and 50–7...

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....

Introduction: Ovarian stimulation syndrome (OSS) in an infrequent disorder, in preterm infants under 30 weeks gestation. The are very few cases described in the literature. The immaturity, lack of gonadal axis feed-back or mutations in the FSH receptor genes, may explain its physiopathology. We present the case of a 26-week neonate with this syndrome.Case summary: 26-week newborn with extremely low weight (460g) born by emergency cesarean section due to ...

Introduction: Children with hypothalamic dysfunction, e.g. due to a genetic or acquired cause such as suprasellar tumours, often suffer from hyperphagia and/or decreased resting energy expenditure (REE). This process induces uncontrollable weight gain, resulting in severe hypothalamic obesity (HO). No effective treatment is available yet for HO. Amphetamines are psychostimulants that are known for their appetite reducing and REE stimulating side effects. Here,...

Background: Given the absence of a systematic evaluation of general public’ attitudes towards the storage and use of newborn screening (NBS) blood samples for research in China, we firstly conducted this internet-based survey to explore these issues.Methods: We conducted a national-based internet survey with self-designed questionnaire. We mainly studied three categories: 1) the willingness to have their children’s residual NBS samples used for...

Background: The pycnodysostose is a genetic lysosomal disease wich is characterized by a ostéosclérose of the skeleton, a small and an osseous brittleness. The pycnodysostose is very rare, its exact prevalence is unknown but it is lower than 1/100,000. The disease is discovered at a variable age, has going from 9 months to 50 years. Transmitted according to a recessive autosomic mode of to a deficit in cathepsine K enzyme which plays a central role in the osseous res...
