Background: Increasing number of survivors following hematopoietic stem cell transplantation (HSCT) leads to necessity to focus also on careful monitoring for late effects. High dose chemotherapy and total body irradiation (TBI) is used for conditioning regimen in many patients. Thyreopathies belong to the most frequent among late endocrinopathies.Objective: Aim of the study was to evaluate incidence of secondary thyroid malignancies after HSCT in young ...

Background: Prader–Willi syndrome (PWS) is characterized by a switch in early childhood from failure to thrive to excessive weight gain and hyperphagia with impaired satiety. The underlying mechanism for this switch may involve hyperghrelinemia, but only poor data exists regarding levels of acylated ghrelin (AG), unacylated ghrelin (UAG), and the AG/UAG ratio in PWS.Objective and hypotheses: To investigate plasma levels of AG and UAG in PWS, compare...

Background: Aortic dilation (AD) occurs in Turner syndrome (TS) increasing the risk of aortic dissection at all ages. There are no current guidelines on what specific aortic diameter measurement should provoke concern in pediatric TS. Because of their small stature, an aortic size index (ASI) has been proposed to normalize the ascending aorta (AA) to body size in young adults’ with TS. However, a more reliable index has been also proposed: the ratio of vascular diameter t...

Background: Ovarian function in young females with cancer can be damaged due to chemo-radiotherapy. One option to preserve fertility in these patients is the cryopreservation of ovarian tissue, but this is still experimental.Objective and hypotheses: Evaluate our experience with cryopreservation (indications, complications, and reimplantation). Through surveys, understand patient perspectives.Method: A total of 63 women were diagno...

Background: Sulfonylurea therapy allows a better metabolic control than insulin in patients with neonatal diabetes secondary to mutation in potassium channel. Its galenic form (tablets) is not suitable for children, as the dosage can’t be easily modulated and as it induces large pharmacokinetics (PK) variations when administer to young children.Objective and hypotheses: To measure relative biodisponibility of a new galenic form of glibenclamide and ...

Objective: Recent experimental data suggest that circulating serotonin interacts with bone metabolism, although this is less clear in humans. This study investigated whether serum serotonin interferes with bone metabolism in young women with anorexia nervosa (AN), a clinical model of energy deprivation.Methods: Serum serotonin, markers of bone turnover (osteocalcin (OC), procollagen type 1 N-terminal propeptide (PINP), type 1-C telopeptide breakdown prod...

Background: There are no available guidelines on hormonal therapy to suppress menstruation in teenagers and young adults (TYA) undergoing chemotherapy.Objective and hypotheses: To review the use of LHRH analogues (LHRHa) (Leuprorelin (L)) or continuous progesterone (Norethisterone (N)) to defer menses in TYA undergoing chemotherapy in a single Institution and initiate guidance on its use.Method: Clinical notes of 27 TYA treated wit...

Retinoic acid receptor agonists can have dramatic negative effects on growth and even induce premature growth cessation and epiphyseal fusion (1, 2). An 11 5/12-year-old, prepubertal girl with fibrodysplasia ossificans progressiva presented in our pediatric skeletal disorders clinic with the concern of early growth cessation. She had participated in a clinical trial of Palovarotene (“MOVE”, NCT03312634), a retinoic acid receptor-gamma agonist, since the age of 9 10/1...

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: Interleukin-6 (IL-6) is a proinflammatory cytokine associated with obesity, insulin resistance, hypertension, and atherosclerosis in adulthood. Few studies have been conducted in healthy young children. We aimed to investigate whether IL-6 levels are associated with cardiometabolic risk factors in healthy 4-year-old children.Methods: From a prospective cohort study named Environment and Development of Children (EDC) cohort, a total of 421 sin...
