Variability of advice and education for steroid sick day dosing in Duchenne Muscular Dystrophy and the impact of the COVID-19 pandemic: Results of a UK wide patient survey

Thakrar S , Cheung MS , Johnson A , Katugampola H , Manzur A , Muntoni F , Mushtaq T , Turner C , Wood C , Guglieri M , Wong SC ,

Introduction: The use of long-term oral corticosteroid in DMD is associated with a range of side effects including secondary adrenal insufficiency. The updated international care consensus (2018) recognizes this important issue and recommends emergency plans to be in place.Aim: This online UK-wide patient survey aims to determine the advice and education given for sick day dosing plans and the impact of the COVID-19 pand...

Turner Syndrome with Neonatal Revelation: Knowing How to Think About It

Ould Mohand Ouamer , Fernane Leila , Sebar Khadidja , Lebane Djamil

Introduction: urner's syndrome (TS) is a rare genetic disorder related to the total or partial absence of an X chromosome, affecting 1/2 500 newborns of female sex. It associates almost steadily a delay in stature and ovarian failure with infertility.The other anomalies are inconstant: morphological features of variable intensity, associated malformations and an increased risk of subsequent acquired diseases.The diagnosis of certainty is established after ...

Social Cognition Skills and Face Perception in Turner Syndrome (TS)

Gepstein Vardit , Anaki David , Zadikov Tal , Hochberg Ze'ev

Background: Patients with TS frequently demonstrate impairments in social cognition difficulties, visual-spatial processing, face and emotion perception.Objective and hypotheses: We examined face perception in the context of perceptual visual dysfunctions and social cognition skills in TS.Method: 26 young women with TS on estrogen replacement therapy, and 26 control participants. They were tested on various cognitive and psychologi...

Metamemory in Turner Syndrome: A Study Comparing Episodic and Semantic Memory

Souchay Celine , Gourisse Laurene , Brigitte Mignot , Magali Avila , Bertrand Anne-Marie , Faivre Laurence

Background: Tuner syndrome (TS) is associated with a distinctive cognitive profile including memory impairments. The current study focuses on metamemory defined as our knowledge about our memory functioning and yet never been explored in TS.Objective and hypotheses: The aim of this preliminary study is thus to determine what patients with TS know about their memory functioning and when their memory is impaired whether or not they are aware of those defic...

Identification of Novel Central Nervous System Imaging Biomarkers Associated with Cognitive Abnormalities in Patients with Congenital Adrenal Hyperplasia

Webb Emma , Elliott Lucy , Carlin Dominic , Wilson Martin , Hall Kirsty , Barrett Timothy , Salwani Vijay , Arlt Wiebke , Krone Nils , Peet Andrew , Wood Amanda

Background: Management of patients with CAH remains challenging. There is increasing evidence to suggest that failure to optimize treatment during childhood not only affects final height but also leads to psychological and psychiatric problems. Previous qualitative structural T2-weighted MRI studies have identified white matter hyper-intensities in up to 46% of CAH patients. The nature and functional relevance of these abnormalities remains unknown.Objec...

24-H Urinary Free Cortisol as a Screening Test for Cushing’s Syndrome in Children

Shapiro Lucy , Elahi Shezan , Baliey Joe , Perry Les , Martin Lee , Grossman Ashley , Akker Scott , Monson John , Drake William , Savage Martin , Storr Helen

Background: Cushing’s syndrome (CS) in children remains a challenge to diagnose and exclude. Published diagnostic guidelines for CS are heavily based upon adult data. The use of 24-h urinary free cortisol (UFC) measurements in the diagnosis of adult CS may have limited use. There is little data on the utility of 24-h UFC in children.Objective and hypotheses: We hypothesised that 24-h UFC is a robust and reliable screening test in children. The study...

Novel LZTR1 mutations in subjects with features of Noonan Syndrome and GH insensitivity negatively regulate GH-induced IGF-I production and hyperactivate GH-induced ERK1/2 activation in response to GH in vitro

Chatterjee Sumana , Romeo Bertola Debora , Agwu Chizo , Maharaj Avinaash , Williams Jack , Cottrell Emily , Shapiro Lucy , Andrews Afiya , Savage Martin O. , Gaston-Massuet Carles , Metherell Louise A. , Storr Helen L. ,

Background: Noonan Syndrome (NS) can overlap clinically and biochemically with growth hormone insensitivity [GHI; short stature (SS), low IGF-I and normal/elevated GH levels]. Mutations in multiple genes regulating RAS/MAPK pathway have been identified in NS including LZTR1 variants. Function of LZTR1 is poorly understood and its role in growth retardation is unknown.Objectives: To functionally characte...

Case Report: the rare case of pediatric myxedema due to an unrecognized chronic autoimmune hypothyroidism

Bonino Elisa , Matarazzo Patrizia , Buganza Raffaele , Tuli Gerdi , Munarin Jessica , Bondone Claudia , de Sanctis Luisa

Hypothyroidism is the most common thyroid disorder in children. It usually presents with nonspecific symptoms, that can be mild and occur slowly over time, compromising a timely diagnosis, with possible effects on pituitary gland, multiple organs and growth. In case of long-standing unrecognized hypothyroidism, myxedema or myxedema coma can occur, rare but severe conditions. This case report describes an adolescent presenting with extensive trunk and neck swelling. After exclu...

Karyotyping of oocytes, granulosa cells and stromal cells in the ovarian tissue from patients with Turner syndrome: a pilot study

Peek Ron , Schleedoorn Myra , Beerendonk Catharina , van der Velden Janielle , Braat Didi , Smeets Dominique , Fleischer Kathrin

Summary Answer: Most primordial/primary oocytes were found to have a 46,XX karyotype. Chromosome patterns of the ovarian cells were different from that observed in other tissues.Background: TS is a chromosomal condition associated with partial or complete absence of one of the two X-chromosomes. Females with TS have a limited reproductive lifespan due to an accelerated loss of germ cells. It has been hypothesized that vi...

Serum Endocan Levels as a Marker of Endothelial Dysfunction in Turner Syndrome and Correlation with Cardiac Findings

Gencay Ali Genco , Darendeliler Feyza , Nisli Kemal , Karaca Serra , Kardelen Asli Derya , Poyrazoglu Sükran , Bas Firdevs

Background: The most common reason for the increased mortality and morbidity in TS, which results from partial or complete deficiency of an X chromosome in a female, is acquired cardiovascular disease, which is the result of endothelial dysfunction that causes atherosclerosis. Endocan, an inflamatory marker, has been found elevated in several diseases with endothelial dysfunction (ED). There is no study of endocan levels in TS.Ob...
