Central precocious puberty in boys: clinical decision-making and secular trend

Huttunen Heta , Kärkinen Juho , Varimo Tero , J. Miettinen Päivi , Raivio Taneli , Hero Matti

Objective Recent studies suggest that boys are undergoing puberty at a younger age. Further, the number of idiopathic male central precocious puberty (CPP) cases are increasing over time. Only a few studies have evaluated the etiological factors in boys with CPP. We describe the etiology of CPP. Further, we define key auxological and clinical cues indicative of organic CPP (OCPP) and characterize the incidence of CPP.Methods&#x20...

Patients with genetic susceptibility syndromes to thyroid cancer in a tertiary hospital

Andrés Carlos , J. Chueca María , Elcano Leire , Ros Raquel , Berrade Sara , Alonso Angel

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...

Thyrotropin receptor stimulating antibodies in pediatric patients with Graves’ diseases using ultra-rapid turbo bioassay

Bossowski Artur , Hatun Burak , Sawicka Beata , Stożek Karolina , Bossowski Filip , J Kahaly George

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...

Unusual presentation of pheochromocytoma (PCC) and paraganglioma (PGL) in two sisters with von Hippel Lindau disease (VHL)

Vieites Ana , J. Benítez Amanda , Eugenia Rodríguez María , Bignon Horacio , Sansó Gabriela

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...

A patient-centric approach to connected health solutions in paediatric growth hormone therapy

Halabi Ammar , Martin Blaine , Koledova Ekaterina , Giunti Guido , Dimitri Paul

Background: There is a clear need for improved patient-centric approaches in the treatment of chronic conditions, including paediatric growth hormone deficiency (GHD). Greater understanding of the patient’s treatment journey has the potential to inform clinical decisions and to improve clinical- and patient-reported outcomes. Connected Health (CH) combines state-of-the-art technologies, tools, methodologies and analytics to create new patient-centric hea...

The effects of dextroamphetamine treatment in children with hypothalamic obesity

Samaan J , Welling MS , de Groot CJ , Abawi O , Burghard M , Kleinendorst L , van der Voorn B , van Haelst MM , Oude Ophuis B , Kamp GA , Rotteveel J , van Schouten-Meeteren AYN , van den Akker ELT , van Santen HM ,

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,...

Response to Crinecerfont Treatment in Adolescents with Classic Congenital Adrenal Hyperplasia Is Correlated with Elevated Baseline Hormone Concentrations but Not Glucocorticoid Dose

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...

The Hypoglycaemia Error Grid: a UK-wide Consensus on CGM Accuracy Assessment in Hypoglycaemia due to Congenital Hyperinsulinism

Worth Chris , J Dunne Mark , Salomon-Estebanez Maria , Harper Simon , W Nutter Paul , Dastamani Antonia , Senniappan Senthil , Banerjee Indraneel

Background and Objective: Continuous Glucose Monitoring (CGM) is gaining in popularity for patients with paediatric hypoglycaemia disorders such as Congenital Hyperinsulinism (CHI), but no standard measures of accuracy or associated clinical risk are available. A small number of studies have shown suboptimal accuracy of CGM in CHI but assessments have been inconsistent, incomplete and offer no measure of clinical application. Error grids that categorise clinic...

Surprisingly high frequency of pituitary stalk thickening in pediatric patients during COVID-19 pandemic in Chile.

Zepeda Diego , Peña Fernanda , Pablo Fernandez Jose , Okuma Cecilia , Naudy Cristian , J Guarda Francisco , Isabel Hernandez Maria

Introduction: Pituitary stalk thickening (PST) is a rare condition in pediatric patients. As there are few studies published in pediatric population, the definition has been difficult to establish. The etiologies involved in PST can be divided in neoplastic, congenital, inflammatory/infectious or autoimmune diseases. In children the most frequent causes are neoplastic, followed by congenital lesions. The inflammatory/infectious and autoimmune diseases are rare...

Early adrenal activation in boys with Cystic Fibrosis may explain impaired final height

Tamer Gizem , GM Arets Hubertus , K van der Ent Cornelis , M van Santen Hanneke , J van der Kamp Hetty

Background: Rapid BMI increase in early childhood was found to be a contributing factor for impaired final height in boys with Cystic Fibrosis (CF). This may be explained by early adrenarche triggering an accelerated bone maturation resulting in a compromised growth spurt during puberty, comparable to children with SGA. In healthy Dutch boys, adrenarche starts from the age of 9 years with DHEAS ≥ 1 µmol/L. In Dutch girls, the onset of adrenarche is fr...
