Background: FOXE1 gene variants containing alterations in the alanine tract length may confer susceptibility to primary ovarian insufficiency (POI). BMP15 gene variants have also been related to POI.Objective and hypotheses: To evaluate the contribution of FOXE1 and BMP15 variants in the pathogenesis of POI and to investigate the hypothesis of digenic inheritance in this disorder.Method: FOXE1 and BMP...

Background: Disproportional short stature (DSS) is the most frequent clinical presentation of skeletal dysplasias, which are a heterogeneous group of more than 450 disorders of bone. Skeletal survey is important to establish the diagnosis and to guide the genetic test, but has several limitations, especially in mild and atypical cases.Objective and hypotheses: To identify the genetic aetiology of DSS by exome sequencing.Method: Who...

Objective: The complex clinical phenotypes arising from HNF4A and HNF1A mutations are similar and include diazoxide-responsive CHI from infancy and maturity-onset diabetes of the young (MODY) from adolescence. We aimed to characterise the clinical and genetic aspects of a cohort of paediatric patients with HNF4A or HNF1A mutations.Methods: Patients from five international centres over ...

Objective: KIGS (Pfizer International Growth Survey) was a large, international database of pediatric patients who received recombinant human growth hormone (rhGH) as prescribed in real-world clinical settings. This analysis evaluated the long-term safety and efficacy data from all participants until KIGS close in 2012.Methods: Children with growth disorders and treated with rhGH (Genotropin® [somatropin]...

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Introduction: Ovary development was once considered a largely passive process. RNA sequencing (RNAseq) approaches have allowed us to begin to characterise ovary development in previously unparalleled detail, revealing the process to be complex and, still, little understood. A challenge is synthesising and using these data to advance our understanding of clinical disease. Through a clinically-focused lens, we elucidate novel aspects of the transcriptional lands...

Background: Fatty liver disease in children and adolescents is the most common cause of chronic liver disease in many countries. Criteria for a diagnosis of pediatric metabolic associated fatty liver disease (MAFLD) are based on hepatic steatosis in ultrasound, blood biomarkers or liver biopsy in association with one of the three criteria: excess adiposity (overweight, obesity or abdominal obesity), prediabetes or type 2 diabetes, or evidence of metabolic dysr...

Introduction: Management of children with adrenal disorders such as congenital adrenal hyperplasia involves thorough clinical monitoring, including measurements of plasma renin concentrations (PRC) and ACTH. However, sex- and age-related reference intervals (RIs) for PRC and ACTH using novel immunoassays are needed.Aim: To evaluate circulating concentrations of renin and ACTH in children and adolescents from the general ...

Background: Paracetamol is the preferred analgesic and antipyretic during pregnancy. Experimental studies suggest that in-utero exposure to paracetamol disrupts ovarian follicle formation and future ovarian function. This may secondarily affect uterine growth. Female minipuberty is characterized by HPG activity and follicle maturation, however individual levels of reproductive hormones fluctuate considerably.Primary Aim:...

Introduction: The pubertal transition is accompanied by voice break in boys. Studies asking men to retrospectively recall their age at voice break report an average age of voice break corresponding to 13.4-14.0 years. However, it may be difficult to remember precisely when your voice broke, and recall bias is quite large. Little is known about voice frequency in boys and girls in relation to pubertal timing.Aim: To asses...
