Background: Primordial dwarfism (PD) is a phenotype characterized by profound growth retardation and microcephaly that is prenatal in onset. Recently mutations in genes involved in ciliogenesis have been described in patients with primordial dwarfism phenotype. In 2012 mutations in rotatin (RTTN), a protein involved in cilia structure and function, have been described in in individuals with bilateral diffuse polymicrogyria, but not growth failure.Case pr...

Background: The association of NF1 with optic pathway glioma (OPT) and GH hypersecretion was initially described in some isolated cases, while the presence of PP was more frequently reported in these patients. Association of gigantism and precocious puberty (PP) in five children with OPT (isolated in two and associated with NF1 in three cases) has been recently published.Aims: To evaluate the frequency of GH hypersecretion in children with NF1 and OPT, t...

Background: Central precocious puberty (CPP) is often familial but its genetic cause is largely unknown. Very recently, the makorin RING finger protein 3 (MKRN3) gene, located on chromosome 15 in the Prader-Willi syndrome (PWS)-associated region (15q11-q13), has been found mutated for the first time in five families with familial precocious puberty, with a peculiar kind of transmission. In fact, it is an imprinted gene which is expressed only if transmitted from the father. Th...

Background: Studies examining vitamin D levels in association with childhood obesity usually do not concurrently measure levels of vitamin D-binding protein and do not calculate the unbound, bioavailable vitamin D, that is considered the fraction of 25-hydroxyvitamin D able to exert biological activity.Objective and hypotheses: To evaluate in a group of children for the most part obese i) the concentrations of both total 25-hydroxyvitamin D and of the bi...

We present the case of a five-day female admitted to our Paediatric Unit due to TSH elevation (bTSH 303 mIU/L) on routine neonatal screening for congenital hypothyroidism (CH). The patient was born at 38 weeks’ gestation by c-section presenting with adequate auxological parameters. Her mother suffered from Hashimoto’s disease, already diagnosed before pregnancy, and requiring Levo-thyroxine therapy (L-T4). Blood tests performed at five days of life revealed the pre...

Background: Short stature is a common problem in children. This study aimed to determine the cause of short stature in children in Rasht is 2–15 years.Methods: This study was done on 148 children aged 2–15 years with short stature in 2008–2011 shorter 17 Shahrivar patients have been conducted. Demographic characteristics of children, child, and family history of the disease, blood tests, hormone stimulation test growth, physical examinatio...

Background: The patatin-like phospholipase domain-containing protein 3 (PNPLA3) I148M and the transmembrane 6 superfamily member 2 (TM6SF2) E167K polymorphisms have been recognized as the major risk polymorphisms for Non-Alcoholic Fatty Liver Disease (NAFLD). Data supported a close relationship of NAFLD with thyroid function both in adults and children. To investigate the influence of NAFLD and of its genetics on thyroid function.<p class...

Purpose: Leptin plays a key role in the regulation of body weight and other endocrine systems. Recently, impairment of leptin gene transcription due to genetic variations in a long-noncoding RNA, also referred as lncOb, has been described in mice. In humans, a correspondent polymorphism (rs10487505) has been associated with relatively low plasmatic leptin levels compared to obesity severity and with early obesity onset.Objectives...

Background: The patatin like phospholipase containing domain 3 (PNPLA3) I148M polymorphism has an effect on modulation of estimated glomerular filtration rate (eGFR) in non-obese non-diabetic adults and in children with histologically confirmed Non-Alcoholic Fatty Liver Disease (NAFLD).Objectives: To explored the impact of PNPLA3 I148M polymorphism on eGFR in obese children with and without NAFLD.<p class="a...

Introduction: Short stature is defined as stature less than −2 standars deviations (SD) for a person’s age and sex of the reference population. Short for gestational age children (SGA) represent 20% of all children with short stature. 10% of these can not catch-up and remains their height below −2 SD. Growth hormone (GH) treatment is a recognized therapy for SGA children authorized in Europe at 4 years old. There are studies that support that younger children ...
