Allan-Herndon-Dudley syndrome: case report of a rare disorder

Navasardyan Lusine , Muradyan Irina

Introduction: Allan-Herndon-Dudley syndrome (AHDS) is an X linked disorder – mutation of monocarboxylate transporter 8 (MCT8) gene. It leads to a severe psychomotor retardation, significant hypotonia of the skeletal muscles, spastic or dystonic quadriplegia. MCT-8 is responsible for the uptake of T3 by neurons of CNS. AHDS is characterized by increased T3 concentration, increased T3 / T4 ratio, TSH not depressed, even slightly elevated levels. Because of impossibility f...

Monogenic forms of neonatal diabetes: our casuistics and evolution

Ángeles Santos Mata María , Pacheco Carrillo Aitana , Ruiz Ocaña Pablo , Macías López Francisco

Neonatal diabetes (ND) occurs in 1/100,000-150,000 newborns with hyperglycemia in the first six months of life, requiring insulin treatment for at least two weeks, with no autoimmune basis. Two forms are described, transitory (TND) and permanent (PND). In 50% cases of TND, remission presents within the first year of life, only to relapse later before puberty in 50% of cases.CASE 1: Newborn with sustained hyperglycemia since the third day of life, requiri...

Incidence of differences of sex development in Switzerland 2000-2019

Metzger Sara , Sommer Grit , Flück Christa , DSD Cohort Study Group Swiss

Background: Differences in sex development (DSD) comprise a large group of rare, mostly genetic disorders along the path of human sexual development. Since the Chicago Consensus, health care providers group them in sex chromosome DSD, 46,XY and 46,XX DSD with subgroups regarding their effect on sex hormone synthesis, action or excess, on gonadal development, and others. Incidence of rare DSD is not well established despite public interest.<p class="abstext...

MIRAGE Syndrome, a Novel Syndromic form of Primary Adrenal Insufficiency

Chin Xinyi , Sreedharan Aravind Venkatesh , Ting Teck Wah , Vasanwala Rashida Farhad

Primary adrenal insufficiency (PAI) is a rare but potentially life-threatening disease. When this happens very early in life, genetic causes should be considered. Here, we report a newborn who presented with hyperkalemia, hyponatriemia, hypoglycaemia and generalised hyperpigmentation, and was found to have primary adrenal insufficiency. This child also had concurrent issues of poor growth, sepsis and persistent pancytopenia. She was eventually diagnosed with MIRAGE syndrome (M...

Placental measurements in relation to gestational age (GA) and fetal growth Characteristics (SGA, AGA and LGA) in a large Cohort in Qatar(n= 80722).

Alyafei Fawzia , Soliman Ashraf , Olukade Tawa , Alqubaisi Mai , Alaaraj Nada , Ali Hamdy

Background: Epidemiological studies have shown associations between placental weight (PW) and perinatal and postnatal linear growth and weight gain.Objectives: To report trimmed placental weight (PWT) and evaluate their association with birth weight (BWT), and gestational age (GA) in a large cohort of mother/ baby pairs in Qatar. (n= 80722).Methods: Retrospective data anal...

POU1F1 gene mutation as a cause of central hypothyroidism and growth hormone deficiency: a case report

Sawicka Beata , Borysewicz-Sańczyk Hanna , Sztatyłowicz Aleksandra , Michalak Justyna , Stożek Karolina , Bossowski Artur

Background: Thyroid hormones are necessary for normal child development. Hypothyroidism, associated with insufficient amounts of free triiodothyronine and thyroxine, may not only cause poor growth rate, but also results in impaired central nervous system development. In Poland, newborn screening for congenital primary hypothyroidism, the incidence of which is reported to be 1:2500- 1:4000 births, has been performed for many years. Secondary hypothyroidism, cau...

Neonatal Screening for Congenital Hypothyroidism: Analysis of a Large Coorte of Affected Patients (1987-2017) and Relationship with Perfluoroalkylated Substances (Pfas) in North-Eastern Italy

Gaudino Rossella , Beccherle Federico , Cavarzere Paolo , Lauriola Silvana , Camilot Marta , Teofoli Francesca , Vincenzi Monica , Rizzoli Christian , Antoniazzi Franco

Background: Recent studies have analyzed the influence of perfluoroalkylated substances – PFAS (in particular PFOS and PFOA) on people and thyroid. Children are primaly affected by these pollutants. On the other side variation of incidence of congenital hypothyroidism (CH) has been shown in recent years by different studies. We sought to determine whether the incidence of CH in north-eastern Italy has changed in relation to some endocrine disruptors and t...

Hypercalcemia due to Six Newly Identified Inactivating Mutations in the CaSR Gene

Kor Yılmaz

Introduction: Heterozygous inactivating mutations that occur in the calcium sensing receptor (CaSR) gene often lead to benign mild to moderate and parathormone (PTH) dependent familial hypocalciuric hypercalcemia (FHH). Neonatal severe hyperparathyroidism is a clinical condition that develops due to homozygous inactivating mutations in the CASR gene and results in severe, life-threatening hypercalcemia. In this study, we aimed to discuss the differences in clinical, genetic, l...

The Influence of Oil-Soluble Iodinated Contrast Medium (Lipiodol) on Child’s Thyroid Function in Mice

Introduction: Hysterosalpingography using oil-soluble iodinated contrast medium (ethiodized oil; Lipiodol) is a common examination for patients with infertility. Lipiodol remains in the body long after the examination, and there are some reports suggesting that Lipiodol induces thyroid dysfunction not only to the mother but also the fetus and the newborn. However, since there are no known mouse models of Lipiodol-induced thyroid dysfunction, we examined the influence of Lipiod...

The Effect of Intrauterine Stress on Leukocyte Telomere Length in Newborns

Background: Telomeres are specialized nucleoprotein structures located at the ends of chromosomes playing a crucial role in genomic stability. They consist of tandem repeats of the noncoding hexameric TTAGGG sequence. Telomere shortening has been associated with cardiovascular disease, hypertension, type 2 diabetes, atherosclerosis, coronary heart disease and stroke, and has been proposed as a biomarker for ageing and a prognostic factor for age-associated diseases.<p clas...
