Introduction: Few studies have been published comparing the liquid and tablet formulations of L-T4 in pediatric patients, with a short follow-up period. Both formulations seemed to produce a rapid normalization of thyroid fuction with a tendency of a greater TSH inhibition in children taking the L-T4 liquid drops. The aim of our study is to compare the long-term effectiveness and saftey of both liquid and tablet L-T4 therapy in CH patients up to 3 years old via a multicenter s...

Background: Children with familial forms of central diabetes insipidus (CDI) display polyuria and polydipsia within the first years of life.Objective and hypotheses: We hypothesize that children with an early-onset idiopathic CDI might be affected by de novo genetic mutations.Method: Eleven children aged between 1 month and 7 years with polyuria and polydipsia and negative family history were enrolled. In nine of them with...

Background: The replacement therapy with levo-thyroxine (LT4) in congenital hypothyroidism (CH) aims to ensure normal growth and neuropsychological development. Few data are available about the appropriate dose during childhood and early adolescence.Objective and hypotheses: i) To evaluate LT4/kg per day requirement from diagnosis until 12 years of age; ii) to assess any differences in relation to the different etiology of CH as concern...

Background: There is still need to define permanent GHD after adult height achievement in young adults with childhood-onset GHD (COGHD).Objective and hypothesis: To reassess GH response during transition.Method: We present the final data of 129 subjects (71M) recruited from a multicenter cross-sectional observational study, in whom anthropometrics, ITT (n=99), GHRH–arginine (n=122), IGF-1 evaluations were und...

Background: Primary IGF1 deficiency can result from molecular defects in genes encoding for the GHR, IGF1, STAT5b and ALS. Heterozygous, activating mutations in the STAT3 gene have been recently described in children with severe growth failure associated with a spectrum of early-onset autoimmune disease.Case presentation: We report the molecular diagnosis in two unrelated patients with severe growth failure and IGF1 deficiency: P1, a 3.6 year ol...

Objective: To study the clinical features and gene mutations of neonatal diabetes mellitus (NDM) in Chinese patients.Methods: Patients with clinically diagnosed NDM were subjected to genetic screening by targeted gene capture of the genes associated with glucose metabolism, and followed up.Results: Of the 23 cases of NDM studied, 16 (69.6%) were permanent neonatal diabetes mellitus (PNDM), 6 (26.1%) were transient neonatal diabetes...

Background: Linear growth in patients with congenital hypothyroidism (CH) born in 1970s and 1980s is reported normal.Objective and hypotheses: To evaluate whether the earlier diagnosis and the higher L-T4 starting dose lead to an improvement in growth and pubertal outcome over the last two decades.Method: Two-hundred and fifteen patients with permanent CH born in 1980s and 1990s (age at diagnosis 25.1&#177...

Background: Foramen magnum stenosis (FMS) is a life-threatening complication in children with achondroplasia (ACH) which may require cervicomedullary decompression (CMD). There is no evidence if FMS and CMD affects growth in children with ACH.Aim: To evaluate the impact of FSM and CMD surgery on anthropometric measurements in children with ACH.Methods: Sixty-five patients with ACH ...

Background: In pediatric practice, as a rule, differential diagnostics between the three main types of diabetes insipidus DI is to be made: central DI, renal DI and physiological polydipsia of infants – the separation of which is extremely important for the prescription of pathogenetic treatment.Objective: To make a differential diagnostics of various forms of DI.Methods: The study involved 14 patients (ten girls and four boys...
