Royal Jelly Supplementation Induces the Growth Plate Development and Increases Plasma Growth Hormone and Oestradiol Levels in Prepubertal Rats

Sever Murat , Pirgon Ozgur , Ciris Metin , Aydin Bunyamin

Background: In recent years families, especially in the children’s growth and development, often use alternative treatments as growing more healthy individuals.Objective and hypotheses: The purpose of the present study was to examine the hormonal, histomorphometric and immunohistochemical effects of Royal Jelly (RJ), which was a growth supplement commonly used by parents for their children, on growth plate of young rats.Method...

Silver-Russell Syndrome without Body Asymmetry in Three Patients with Duplications of Maternally Derived Chromosome 11p15 Involving CDKN1C

Nakashima Shinichi , Kato Fumiko , Kosho Tomoki , Nagasaki Keisuke , Kikuchi Toru , Kagami Masayo , Fukami Maki , Ogata Tsutomu

Background: Silver-Russell syndrome (SRS) is a congenital developmental disorder characterised by pre- and post-natal growth failure, relative macrocephaly, hemihypotrophy, and fifth-finger clinodactyly. Recent studies have shown that gain-of-function mutations of CDKN1C result in IMAGe syndrome (IMAGeS) characterized by intrauterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita, and male genital abnormalities, whereas less severe gain-of-function mut...

Mutation in RTTN, a Regulator of Ciliary Function, Causes a Complex Syndrome Characterized by Severe Congenital Microcephaly, Lissencephaly and Profound Growth Failure in Two Siblings

Grandone Anna , Nigro Vincenzo , Torella Annalaura , Festa Adalgisa , Luongo Caterina , Marzuillo Pierluigi , Coppola Ruggero , del Giudice Emanuele Miraglia , Perrone Laura

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...

Chronic Effects of Bisphenol A Administration on Growth Hormone Activity

AL-Masroori Mohammed , Hebais Mohammed , AL-Araimi Amnah , Zadjali Fahad

Background: Bisphenol A (BPA), a plastic byproduct, is a known endocrine disruptor and is types of cancers, such as prostate and ovaries, and some other health conditions, for instance diabetes and obesity. It has direct effect on reproductive system through its strong oestrogen agonist activity.Objective and hypotheses: BPA has a strong oestrogen agonist activity. And oestrogen antagonize cellular activity of growth hormone (GH), however, the effect of ...

Severe IGF1 Deficiency and Multi-Organ Autoimmune Disease Associated with Novel Germline STAT3 Mutations

Scaglia Paula , Keselman Ana , Gutierrez Mariana , Domene Sabina , Blanco Miguel , Sanguinetti Nora , Bezrodnik Liliana , Di Giovanni Daniela , Caldirola Maria Soledad , Martucci Lucia , Karabatas Liliana , Kumar Ashish , Jones Nana-Hawa , Hwa Vivian , Revale Santiago , Vazquez Martin , Jasper Hector , Domene Horacio

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...

Various Imprinting Disorders Underlying Silver-Russell Syndrome-Compatible Phenotype

Kagami Masayo , Matsubara Keiko , Sano Shinichiro , Nakamura Akie , Mizuno Seiji , Hamajima Naoki , Yanagisawa Atsuhiro , Hashimoto Miyuki , Yukote Akira , Fukami Maki , Ogata Tsutomu

Background: Silver-Russell syndrome (SRS) is a rare congenital developmental disorder characterised by pre- and postnatal growth failure, relative macrocephaly, triangular face, hemihypotrophy, and fifth finger clinodactyly. Hypomethylation of the H19-DMR and maternal uniparental disomy chromosome 7 (UPD(7)mat) were identified in about 30 and 10% of SRS patients respectively. Genetic causes of the remaining 60% of the patients are unknown. Growth failure, small hands, and hypo...

Ligase IV Deficiency Syndrome as a Cause of Microcephalic Primordial Dwarfism in Dizygotic Twins

Girardin Celine , Ranza Emmanuelle , Klee Philippe , Dirlewanger Mirjam , Caflisch Marianne , Bottani Armand , Schwitzgebel Valerie

Background: Microcephalic primordial dwarfism (MPD) is a group of rare genetic disorders defined by severe growth restriction of both prenatal and postnatal weight (W), height (H), and particularly head circumference (HC).Objective and hypotheses: To elucidate the genetic origin of the MPD in dizygotic twins.Method: Exome sequencing of 19 genes known to be implicated in microcephaly was performed.Results: Diz...

High Frequency of Hypomorphic Allelic Haplotypes of the gh1 Proximal Promoter in Patients with Proportional Undergrowth and Isolated GH Deficiency

Campos-Barros Angel , Gomez-Nunez Ana , Zurita-Munoz Olga , Gallego-Gomez Elena , Cruz-Rojo Jaime , Garzon Lucia , Luzuriaga-Tomas Cristina , Riano-Galan Isolina , Bezanilla-Lopez Carolina , Donate-Legaz Jose Maria , Marban-Calzon Mercedes , Ruperez Sara , Hermoso Florinda , Lara-Orejas Emma , Borras-Perez Ma Victoria , Rius-Peris Jose Manuel , Garcia-Cuartero Beatriz , Gonzalez-Casado Isabel

Background: Although isolated GH deficiency (IGHD) is one of the most frequent causes of postnatal proportional undergrowth, up to 85–90% of IGHD cases are still classified as idiopathic. On the other hand, previous reports identified up to 40 different GH1 proximal promoter haplotypes, some of which show hypomorphic effects, significantly reducing GH1 expression levels.Objective and hypotheses: To investigate the frequency of ...

GH Excess in McCune–Albright Syndrome

Tessaris Daniele , Boyce Alison M , Matarazzo Patrizia , Lala Roberto , Collins Michael T

Background: McCune–Albright Syndrome is a combination of polyostotic fibrous dysplasia (BFD), café’-au-lait skin pigmentation and hyperfunctioning endocrinopathies. It results from postzygotic mutations in a-subunit of the Gsalfa protein and the consequent phenotype is a mosaic with high degree of clinical variability.Objective and hypotheses: The aim of the study is determine prevalence and characteristics of GH hypersecretion (GHH) in MA...

GH Hypersecretion in Children with NF1 and Optic Pathway Gliomas

Pedicelli Stefania , Cambiaso Paola , Macchiaiolo Marina , Galassi Stefania , Mastronuzzi Angela , Del Bufalo Francesca , Ubertini Graziamaria , Cappa Marco

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...
