The new techniques of molecular genetics are revolutionizing our clinical practice. This causes benefits in the diagnosis and prediction of diseases in patients, but also raises new ethical concerns that must be addressed. One of them is the susceptibility to cancer due to genetic risk. Children can be especially vulnerable in this area, as they do not freely decide the way forward. Regarding thyroid cancer, it is important to know which genetic syndromes are susceptible to ca...

Background: Thyrotropin receptor (TSH-R) stimulating autoantibodies (TSAb) are present in 90-100% of patients with Graves’ disease (GD). TSAb are functional, impact thyroid function, and are clinically relevant. This study we performed in a pediatric patients with dynamic of Graves’ disease before and during methimazole therapy and in patient with Hashimoto’s thyroiditis using a novel and ultra-rapid TSAb andTBAb bioassay.<p class="abstex...

Introduction: Von Hippel-Lindau disease(VHL) is an autosomal dominantly inherited tumor syndrome that predisposes to development benign and malignant tumors. The prevalence of VHL disease is one in 36,000, and the penetrance is higher than 90%. PCC occur in up to 20% of VHL patients. Classically, it is characterized by having an adrenal location, mostly bilateral and being derived from the sympathetic nervous system, resulting in the releases of catecholamines...

Background: Primary amenorrhoea is a rare condition characterised by absent menarche. Based on gonadotropin levels, we distinguish hyper from hypogonadotropic hypogonadism forms.Objective and hypotheses: Herein, we present a case of primary amenorrhea with hypergonadotropic hypogonadism and glomerulopathy.Method: A 27-year-old female presented for evaluation of primary amenorrhea and incomplete pubertal development. Her past medica...

Background: The influence of GH on prepubertal children with Kabuki Syndrome (KS) is a novel field of research. KS is a congenital anomaly/intellectual disability syndrome caused by a mutation in the KMT2D or KDM6A gene. These mutation causes distinct phenotypically features, such as short stature and facial dysmorphology. Earlier studies describe a high incidence of obesity in children with KS.Aims and objectives: In this prospective s...

Background: The influence of growth hormone (GH) on the metabolism of prepubertal children with Kabuki syndrome (KS) was never investigated before. Kabuki syndrome (KS) is a rare syndrome, which is mainly characterized by mental retardation, short stature, specific facial features, obesity and hypotonia. This syndrome caused by a mutation in the KMT2D or KDM6A gene.Objective and hypotheses: In this prospective study we investigated the ...

Background: The growth process that transforms a newborn into an adult implies that there is not only an increase in height but above all a constant change in body proportions. Knowledge of the body proportions gives insight into the natural process of maturation and any disturbance can be used as a diagnostic tool.Objective and hypotheses: Manual measurement of body dimensions is a highly time-consuming procedure requiring a variety of measurement tools...

Background: Kabuki syndrome (KS; OMIM 147920) is a congenital anomaly/intellectual disability syndrome caused by a mutation in the KMT2D or KDM6A gene. Children with KS have a spectrum of clinical features, but one of the key features in KS patients is postnatal growth retardation. GH deficiency has been reported in some children with KS, but no structural research is done in this field.Objective and hypotheses: We studied the growth ho...

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,...

Introduction: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is a rare, autosomal disorder characterized by deficiency of cortisol and oftentimes aldosterone, elevated adrenocorticotropic hormone (ACTH), and excess androgen production. In a phase 2 study of adolescents with classic 21OHD, 14 days of treatment with the corticotropin-releasing factor type 1 receptor (CRF1) antagonist, crinecerfont, led to median percent red...
