Identification of Characteristic Neurological Complications in Infants with Achondroplasia by Routine MRI Screening

Dougherty Harry , Shaunak Meera , Irving Melita , Thompson Dominic , Cheung Moira S

Background: Achondroplasia is the commonest type of skeletal dysplasia with an incidence of 1 in 20,000 and is due to recurrent and dominantly transmitted, activating mutations in Fibroblast Growth Factor Receptor 3 (FGFR3). Complications during infancy include foramen magnum stenosis and hydrocephalus which may lead to neurological morbidity and sudden unexplained mortality. Early detection and appropriate neurosurgical management can prevent these complications. How...

A Rare Form of Ovotesticular DSD: Diagnostic and Management Challenges

Narayan Kruthika , Alderson Julie , Nicoll Nicky , Nicholls Guy , Smithson Sarah , Crowne Elizabeth

We report mosaic triploidy 69XXY/46XX in ovotesticular DSD which poses significant diagnostic and management questions.Case: A baby born to non-consanguineous parents after a normal pregnancy, presented with atypical genitalia including significant clitoromegaly, a urethral opening in the anterior perineum and a normal vaginal opening. Bilateral masses were noted in the labio-scrotal folds. Pelvic ultrasound identified a normal uterus however the gonads ...

STK11 gene variant (Peutz-Jeghers Syndrome) presenting with unilateral pre-pubertal gynaecomastia and macro-orchidism without muco-cutaneous pigmentation or gastrointestinal symptoms.

Shaunak Meera , Side Lucy , Afzal Nadeem , Davies Justin ,

Introduction: We report two siblings presenting with pre-pubertal gynaecomastia and macro-orchidism, who were later diagnosed with Peutz-Jeghers Syndrome (PJS) secondary to a STK11 gene variant. Importantly neither child fulfilled the clinical criteria for diagnosis at presentation, with no muco-cutaneous pigmentation nor gastrointestinal symptoms.Case report: Sibling 1 was referred to Paediatric Endocrinology aged 4 years with ...

A Survey on Clinician Perceptions of Long-Acting Growth Hormone Analogs

Howard-James Naomi , Padidela Raja , Raimann Adalbert , Gevers Evelien , Semler Oliver , McDonnell Ciara ,

Background: Daily recombinant human growth hormone (rhGH) has been utilized since 1985 and has been proven to increase height velocity and improve body composition in growth hormone deficiency, various genetic syndromes and chronic kidney disease. Safety and efficacy are well established. Long-acting growth hormone (LAGH) analogs have been developed to improve compliance and patient experience. There are several LAGH preparations in development or early commer...

Long-term GnRHa use and bone health in transgender adolescents: can a mouse model inform clinical practice?

Ciancia Silvia , Dubois Vanessa , Claessens Frank , Craen Margarita , Doms Stefanie , El Kharraz Sara , Kim Nari , Klink Daniel , Vanderschueren Dirk , Cools Martine

Background: Transgender individuals increasingly present at gender services in childhood. Consequently, to suppress pubertal development, more adolescents are long-term exposed to gonadotropin-releasing hormone analogues (GnRHa), from onset of puberty until start of gender-affirming hormones (GAH), around 16 years. Prolonged GnRHa may compromise bone health more than shorter-term treatment. If earlier start of GAH, when psychologically indicated, may partially...

Evaluation of two cases with 46,XX and 46,XY karyotypes diagnosed with 17α-hydroxylase deficiency

Introduction: 17α-hydroxylase deficiency (17OHD) is a rare form of congenital adrenal insufficiency characterized with decreased cortisol and sex steroid biosynthesis, overproduction of ACTH, and increased mineralocorticoids. The overproduction of corticosterone hinders the symptoms of glucocorticoid deficiency and causes sodium retention, hypertension, and hypokalemia in severe cases. Affected 46,XX and 46,XY individuals are phenotypically female in the...

4D-Blood+ Proteomic Profiling of Obesity and Metabolic Syndrome in Adolescents

Objective: Obesity accounts for 8.9% of children and adolescents in China, and metabolic syndrome (MetS) accounts for 28.8% of obese children, rising year by year. There is no early prediction and screening index in the clinic, so it is urgent to develop early prediction of MetS in children and adolescents and screen pathogenic molecular markers. Therefore, we propose to establish and screen biomarkers for the prognosis of obesity in children and adolescents t...

Introduction: The association between ATD and AIG is very poorly characterized in pediatric age. We review the prevalence of the anti-gastric parietal cells antibodies (APCA) in young patients with ATD and we evaluated the development of AIG during follow-up, in order to define the usefulness of these markers for AIG screening in these patients.Patients and Methods: We evaluated 220 children and adolescents (11.28 ±...
