Background: Noonan syndrome (NS) is a condition caused by pathogenic variants of the genes of the RAS-MAPK pathway. Its clinical manifestations are diverse and include congenital heart disease, short stature, ocular abnormalities, coagulation defects and structural renal anomalies. Our aim was to find out whether the patients with a genetic diagnosis of NS in the West of Scotland were managed according to the Management of Noonan Syndrome guidelines (DYSCERNE)...

Background: Leptin is suggested to be a permissive factor in the onset of puberty by signaling at the level of the hypothalamus to indicate adequate energy stores. Overweight female rats due to increased neonatal nutrition have been shown to develop puberty before normal weight rats.Objective and hypothesis: We hypothesized that this permissive effect may be due not only to increased leptin levels, but also to increased hypothalamic sensitivity to this h...

Introduction: Maternal caloric restriction during gestation leads to offspring’s metabolic programming through epigenetic changes, which increase the risk of developing cardiovascular diseases in adulthood.Objectives: To study in a swine animal model: i) DNA methylation changes associated with caloric restriction during gestation in the adipose tissue of the offspring; and ii) the reversibility of these changes by metformin treatment.<p class="a...

Background: Low serum bilirubin and high serum triglycerides are independently associated with higher risk of developing metabolic syndrome. Both bilirubin and triglycerides can regulate insulin secretion and glucose uptake. This is a first longitudinal study in healthy children to associate bilirubin and the bilirubin/triglycerides ratio with metabolic markers.Objectives: Analyze independent associations between bilirub...

Background: Throughout 2020 telemedicine was rapidly deployed across health services and, during the COVID-19 pandemic, replaced many face-to-face (FTF) medical consultations. Children and young people (CYP) with diabetes present a unique opportunity for this type of consultation, due to the ability to interpret and share glucose data via other platforms. This study describes both CYP and parent experience of a new telemedicine service for CYP with diabetes.</...

Introduction: Isolated growth hormone deficiency (IGHD) type IA causes a severe growth retardation. Their initial good response to exogenous GH is hampered by the development of anti-GH-antibodies leading to treat with IGF1 as the only therapeutic option. Here we present the evolution of a patient with IGHD type IA treated with IGF1r for more than 5 years.Description of the caseWe present a 5-year-...

Background: Neonatal over-nutrition (NON) can increase the propensity to become overweight and develop associated metabolic disturbances in later life. Moreover, some of these long-term effects are sexually dimorphic.Objective and hypotheses: We aimed to determine how NON affects body weight (BW), body composition and triglyceride (TG) and non-esterified fatty acids (NEFA) levels. We hypothesized that the effects would be both age and sex dependant.<...

Introduction: Obesity is known to associate with chronic systemic inflammation. However, hypothalamic inflammation also occurs in response to high fat diet (HFD)-induced obesity and is proposed to participate in central insulin/leptin resistance and the perpetuation of weight gain and systemic affectation. The weight gain and central responses to HFD differ between males and females. As hypothalamic glial cells are implicated in the central inflammatory response we hypothesize...

Background: Childhood adrenocortical tumours (ACT) are rare and have well been described as part of familial cancer susceptibility syndromes which are caused by single gene mutations including P53, MEN1, PRKAR1A, CTNNB1 and APC. Adenomas are the most common ACT, but adrenocortical carcinomas (ACC) occur as well. Childhood ACC can be part of the Li-Fraumeni Syndrome and Beckwith-Wiedemann syndrome. ACC can also occur in familial adenomatous polyposis coli (FAP). FAP is a colon ...

Background: Iodotyrosine deiodinase (DEHAL1) is a thyroidal enzyme that deiodinates mono- and diiodtyrosines (MIT, DIT) and recycles iodine, essential for synthesis of thyroid hormone. Iodotyrosine deiodinase deficiency leads to hypothyroidism, goiter and variable mental retardation. The age for clinical onset was reportedly very diverse, allegedly related to individual iodine nutrition.Clinical case: We report on a boy, offspring of consanguineous paren...
