Tuhan Hale , Donbaloğlu Zeynep , Kırbıyık Özgür , Parlak Mesut , Demir Korcan

Introduction: Resistance to thyroid hormones is defined as lack of response of peripheral tissues to triiodothyronine (T3) which is the active form of thyroid hormones. In general (85%) a mutation is detected in the thyroid hormone receptor β (THRB) gene and more rarely, the thyroid hormone receptor α (TRHA) gene.Case: A 4.7-year-old boy, was admitted to the pediatric endocrinology outpatient clinic of Akdeniz...

Investigating the Incidence of Mild Neonatal Hyperthyrotropinaemia, a Multicentre Study

Howard-James N , McGlacken-Byrne SM , Kernan R , Carolan EC , Murphy NP

Background: Mild isolated neonatal hyperthyrotropinaemia (HTT), defined as elevated thyroid stimulating hormone (TSH) with normal free thyroxine (FT4) concentrations, may be identified by newborn screening programmes for congenital hypothyroidism (CHT) or when neonatal thyroid function tests (TFTs) are performed for a clinical indication. Reported HTT incidence rates vary (from 0.001-0.1%)1. Case definition also varies, with some authors using a TSH...

Burren Christine , Chinoy Amish , Dharmaraj Poonam , David González-Rodríguez Juan , Gueorguieva Iva , Hayes Wesley , Linglart Agnès , Amelia Gómez Llorente Maria , Ríos Héctor , Schnabel Dirk , Harvengt Pol , M.A. Bailey Karen , Glen Fiona , J. Rylands Angela , Williams Angela , Haf Davies Elin

Background: XLH is a rare, genetic, life-long disease caused by PHEX pathogenic variants. It is associated with progressive accumulation of musculoskeletal features and symptoms that evolve across the patient’s lifetime if untreated. Although the disease is well characterised in children and adults, there are limited data describing the health outcomes and experiences of adolescents, particularly at end of skeletal growth (EOSG), a crucial phase during t...

Background: Myo-inositol(MI)is a polyol involved in intracellular signaling pathways of insulin and MI has been used orally for therapeutic purposes in girls and adult women with polycystic ovary syndrome(PCOS)with variable success. As yet, serum MI levels have not been assessed in girls with PCOS.Aim: Our primary goal was to compare serum MI levels in girls with PCOS with those in healthy peers. Secondary goal was to in...

Background: Congenital diabetes insipidus (DI) can be due to mutations in the arginine vasopressin (AVP) gene (familial neurohypophyseal DI), the AVP receptor type 2 (AVPR2) or aquaporin 2 (AQP2) genes (congenital nephrogenic DI, NDI). The clinical manifestation of congenital NDI, especially the response to AVP, can vary greatly depending on the functional effect of the AVPR2 mutation. Here we present two male siblings with NDI and partial response to ddAVP.<p class="abste...

Primary Granulomatous Hypophysitis with Panhypopituitarism, presenting as Aseptic Meningitis in a 14-year-old boy

Stern Eve , R Cohen Zvi , Shrot Shay , Greenberg Gahl , Gruber Noah , Modan-Moses Dalit , Pinhas-Hamiel Orit

Background: Hypophysitis is an uncommon inflammatory disorder of the pituitary gland and is classified both clinically (Primary vs secondary) and histologically (lymphocytic, granulomatous or xanthomatous). Primary hypophysitis is exceptionally rare in the paediatric population with only a few cases reported, the majority being Lymphocytic Hypophysitis.Case Report: We present the case of a previously healthy 14-year-old ...

Short Stature and Single Central Incisor of The Upper Maxillar: Pathogenic Variant in The SHH Gene

Dominguez-Riscart Jesus , Arellano-Ruiz Paola , Garcia-Zarzuela Ana , Modamio-Høybjør Silvia , M Lechuga-Sancho Alfonso

Introduction: The Sonic Hedgehog (SHH) gene is involved in the development of midline structures. Pathogenic variantd in this gene have been associated to holoprosencenphaly 3; Microphthalmia with coloboma 5; Schizencephaly; and Single median maxillary central incisor syndrome (SMMCIS). All of them are inherited in an autosomal dominant pattern and exhibit incomplete penetrance as well as variable expressivity.Case Report:</stron...

A Rare Cause of Proteinuria Presenting with Short Stature, Cataract, and Dysmorphic Findings: Lowe Syndrome with A Novel de Novo Mutation in the OCRL1 Gene

Gürbüz Fatih , Bilginer Gürbüz Berrak , Özalp Yüreğir Özge , Çayır Atilla

Oculocerebrorenal syndrome of Lowe (OCRL) is an X-linked and multisystem disorder with clinical symptoms of congenital cataracts, severe mental retardation, hypotonia, areflexia, and incomplete Fanconi syndrome of the proximal renal tubules. We report a 15-year-old short stature male with a severe form of OCRL syndrome, diagnosed based on bilateral congenital cataract, proteinuria, tubulopathy, and dysmorphic findings. The physical examination revealed a height of 152 cm (-2.7...
