Introduction: Growth prediction algorithms (i.e. iGRO), provide an estimate of a patients’ likely growth in the first year, and subsequent years, of GH treatment at a given dose, taking into account the patient’s combination of physical characteristics. Comparing a patient’s actual growth with their predicted growth after the first year of GH treatment, it is possible to determine whether the patient is responding to GH as expected (Index of responsiveness; IoR)...

Introduction: Transient hyperinsulinism is described in neonates with stress factors (intrauterine growth restriction (IUGR), large for gestational age (LGA), perinatal asphyxia, infants of diabetic mother etc.). Recognition and early treatment is prioritary to avoid neurological morbidity related with recurrent hypoglycemia.Objective: Describe the incidence of transient hyperinsulinism. Clinical charac...

Background: Transsexuality during childhood/adolescence is a complex condition usually ending in dysphoria (GD). The prevalence of transgenderism is increasing in Pediatrics. In the process of sexual reassignment, a correct pharmacological treatment and the knowledge of possible consequences are necessary.Objetive: The objective of this study is to present the evolution of the physical and analytical characteristics and side effects in Transgender childr...

Background: McCune–Albright syndrome (MAS) is a rare disease with a prevalence of <1 to 100 000. It is caused by early post-zygotic mutations in the GNAS1 gene. Classically it presents with precocious puberty, fibrous dysplasia and café-au-lait spots. Other endocrinopathies may be hyperthyroidism, GH excess, Cushing syndrome, and renal phosphate wasting.Case report: A 17-year-old girl diagnosed with MAS at the age of 11 on basis of all thre...

Background: Quality of life (QOL) includes physical, psychological and social aspects. Transgender (TG) children undergo problems in school and with family, friends, and social relationships. These adverse effects on physical and psychosocial health can impair their quality of life.Objective and Methods: This study aims to assess health-related quality of life (HRQOL), using the KIDSCREEN-52 questionnaire (Spanish versio...

Background and Aims: HNF4A-MODY clinical expression is broad, ranging from hypoglycemic hyperinsulinism in the neonatal period and early childhood to hyperglycemia and diabetes, as insulin secretion progressively decreases in adult patients. The main objective was to clinically and molecularly characterize patients with glycemic alterations, negative autoimmunity and confirmed molecular diagnosis of HNF4A-MODY.Materials and Metho...

Though up to fourteen different MODY subtypes have been so far described, there are no studies in the literature which have determined their actual frequency and prevalence in pediatric patients.Objectives: To identify the underlying molecular basis in a cohort of pediatric patients with a suspected clinical diagnosis of MODY by targeted NGS.Materials/Methods: Cohort of 60 patient fulfilling MODY c...

Background: Neurofibromatosis type 1 (NF1) caused by loss of function mutation in the NF1 gene; leads to the hyperactivation of RAS and its downstream mediators and contributes to tumour formation. The main manifestations of NF1 are café au lait macule, axillary and/or inguinal freckling. Neurofibroma plexiform is specific for NF1 and identified on the face and trunk. Urogenital presentation is infrequent in the penis. Identification of this lesion is essential because it...

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. The mechanisms responsible for the development of nonalcoholic fatty liver disease (NAFLD) and progression to nonalcoholic steatohepatitis (NASH) in these patients are incompletely understood. Low serum insulin-like growth factor-1 (IGF-1) levels are associated with increased histologic severity of NAFLD. Growing evidence suggests that growth hormone (GH) and IGF-1 may have r...

Introduction: The dichotomous nature of the definition of Metabolic Syndrome (MS) in both children and adults can under-diagnose subjects at risk and prevents adequate follow-up of therapeutic interventions. Recently, a continuous score of MS (sSMp) was validated in the pediatric population based on the IDF criteria for a population> 16 years.Objectives: To apply sSMp in a Chilean pediatric population cohort and corr...
