Iliev Daniel , Braun Regina , Sanchez-Guijo Alberto , Wudy Stefan , Heckmann Doreen , Bruchelt Gernot , Rosner Anika , Grosser Gary , Geyer Joachim , Binder Gerhard

Here, we report on a female adolescent with overweight and a very high DHEAS serum level. The hypothesis that the origin of DHEAS excess was the presence of either an ovarian or a suprarenal DHEAS-producing tumor was not confirmed. Sonographic and MRT investigations did not support its presence. In addition, effective dexamethasone suppression of DHEA and DHEAS excluded this diagnosis. Steroid sulfatase (STS) hydrolyses alkyl and aryl steroid sulfates to their unconjugated for...

Unexpected impact of sex hormones on B-cells in trans- and cis-gendered healthy young people

Peckham Hannah , Rosser Elizabeth C , Radziszewska Anna , Robinson George , Martin-Gutierrez Lucia , De Gruijter Nina M , Jury Elizabeth C , Butler Gary E , Ciurtin Coziana ,

Background: Cis-gender females are known to mount stronger immune responses to invading pathogens or vaccines than cis-gender males. However, this is also associated with increased risk of autoimmunity. Little is known about the immunophenotypes of transgender individuals on gender-affirming hormonal treatment, despite growing evidence that hormones influence the immune system. Via the process of class-switch recombination (CSR), B-cell immunoglobulin isotype ...

A Case of Sjogren's Syndrome with systemic involvement combined with exacerbated hyperthyroidism improved after glucocorticoid treatment

Lee Donghyun , Sik Kim Heung , Yun Park So , Kang Seokjin

Background: Sjogren’s syndrome is a systemic autoimmune disease, and it is rare in pediatric population. Primary symptoms are dry mouth and dry eyes. However, it may present with systemic manifestations, involving lungs, liver, kidneys, vasculature, and blood. We report a case of Sjogren's syndrome with systemic involvement in a child with Graves' disease.Case report: A 9-year-old 11-month-old girl presen...

Background: Acquired Von Willebrand's syndrome (aVWS) associated with hypothyroidism is rare in children and more often diagnosed during the peripubertal period in the context of Hashimoto's thyroiditis.Case presentation: A 5-year-old girl was referred to the paediatric haematology unit for rectal bleeding, anaemia, and prolonged activated partial thromboplastin time. Her developmental and learning skills were no...

Novel Role(s) for Immunoglobulin Superfamily, Member 1 (IGSF1) in the Hypothalamic–Pituitary–Thyroid Axis

Bernard Daniel

Background: Immunoglobulin superfamily, member 1 (IGSF1) was originally proposed to function as an inhibin co-receptor in pituitary gonadotroph cells. More recently, however, loss of function mutations in the human IGSF1 gene were linked to a novel syndrome of central hypothyroidism, testicular enlargement, and variable prolactin-deficiency. Igsf1-deficient mice are also centrally hypothyroid, with reduced pituitary thyrotropin-releasing hormone receptor (<em...

Background: Crohn’s disease is a relapsing systemic inflammatory disorder with inflammatory bowel disease (IBD) due to up-regulation of pro-inflammatory cytokines including TNFα. More than 80% of newly diagnosed children present with growth failure Paediatric gastroenterology units in the UK submit data to the UK IBD database which can be accessed when required. One aim of current treatment protocols is to promote growth. Studies on the use of anti-TNFα antibodi...

Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare pediatric disorder. The classic form occurs in 1:15,000 births worldwide. Osteogenesis imperfecta is a rare bone disease occurring in 1 in 15,000 to 20,000 births. Cow’s milk allergy (CMA) is of the commonest food allergies in early life. Our case presents the co existence of the abovementioned entities in a patient.Case report:</str...

Background: Research on the impacts of achondroplasia on children's functioning and well-being is limited. The purpose of the study was to investigate the impacts of achondroplasia on children's daily lives to support the development of an impact measure of achondroplasia on children's functioning and well-being.Methods: Individual telephone interviews and one parent focus group were conducted in the United S...

A Case of Infantile Cushing's Syndrome from McCune Albright Syndrome: The Importance of Multiple-Site Sampling for Genetic Testing

Beng Hui Ng Nicholas , Tay Vanerry LQ , Ooi Delicia SQ , Loke Kah Yin

Case Description: We report a case of a 7-month old Vietnamese boy who presented with failure to thrive and a Cushingoid appearance from 1 month old. There was no history of exogenous steroid use. On examination, height and weight were <3rd centile. He was Cushingoid with motor development delay. There were multiple large café-au-lait lesions over the sacral region but no limb asymmetry to suggest fibrous dysplasia.En...
