Background: The current diagnostic criteria for Prader–Willi syndrome (PWS) although widely accepted, is challenging to be implemented in Chinese population.Objective and hypotheses: The present study collected PWS cases from 12 centres across China. By analysing the clinical manifestation during early infancy, we aimed to provide data for clinical characteristics, screening strategy and effect of GH treatment in Chinese PWS patients.<p class="a...

We assessed the risk of metabolic syndrome in children and adolescents who were classified using the tri-ponderal mass index (TMI) with data from the Korea National Health and Nutrition Examination Survey (KNHANES). Data from 10-18-year-old subjects that were overweight or obese (n=1,362) were extracted from the KNHANES 2007-2018. Weight classifications were determined by TMI and included overweight and Class I, Class II, and Class III obesity. The standard deviation ...

Objective: This study aimed to compare clinical parameters, including final adult height (FAH), in girls with central precocious puberty treated with gonadotropin-releasing hormone agonists (GnRHa) with and without growth hormone (GH).Methods: This retrospective study reviewed data of 210 girls with precocious puberty who had reached FAH in a long-term trial of GnRHa treatment. The subjects were divided into the GnRHa tr...

Objective: Central precocious puberty (CPP) is defined as early activation of the hypothalamic-pituitary-gonadal axis. The gonadotropin releasing hormone (GnRH) stimulation test has become widely used in the evaluation of CPP. However, intravenous GnRH is often not readily available for commercial use. Therefore, we aimed to evaluate the diagnostic accuracy of the Triptorelin test compared to the GnRH test.Methods: A tot...

We investigated the reference values of liver enzymes based on cardiometabolic risks among children and adolescents using the Korea National Health and Nutrition Examination Survey (KNHANES). A total of 8,091 subjects aged 10-18 years were included data from 2007-2017. Overall, Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and the AST/ALT ratio varied with sex and age. AST levels tended to decrease with age, but ALT levels had a U-shaped curve, which result...

Objective: We aimed to investigate the usefulness of abdominal adiposity and total body fat as predictors of cardiometabolic health, especially insulin sensitivity, in children and adolescents.Methods: Participants were 479 children and adolescents with obesity (322 boys and 157 girls) aged 3 to 18 years attending the Children's Hospital at Zhejiang University School of Medicine (Hangzhou, China). Participants underw...

Purpose: Noonan syndrome (NS) is a genetic disorder characterized by specific features including short stature, cardiac defect, and distinctive facial dysmorphism. Human growth hormone (GH) has been used to improve growth in children with NS but there is little information how GH treatment affects height. The aim of this study is to investigate efficacy of GH treatment in Korean children with NS compared to sex and age-matched patients with growth hormone defi...

Objective: To determine the effect of gonadotropin-releasing hormone agonist (GnRHa) treatment on auxological outcome of Korean boys with central precocious puberty (CPP) and early puberty (EP).Methods: This study included 11 boys with CPP and 8 boys with EP who were treated with GnRHa for at least 2 years at the Pediatric Endocrine Unit of Ajou University Hospital from March 2003 to December 2015. All nineteen boys atta...

Background: Management options are limited for the treatment of Graves' disease (GD) in children and adolescents. Antithyroid drugs (ATDs) remain the first-line therapy in patients with GD, despite a high relapse rate. We investigated the clinical characteristics, treatment, the outcome, and predictors of a remission of children and adolescents with GD at a single center.Methods: We retrospectively reviewed the medic...

Hyponatremia with hyperkalemia in infancy may be seen in many endocrinologic and metabolic disorder such as congenital adrenal hyperplasia, congenital adrenal hypoplasia, and other forms of hypoadrenalism in infancy. Here, we report a infants who presented with hyponatremia with hyperkalemia finally diagnosed as pseudohypoaldosteronism (PHA) due to urinary tract infection (UTI) with reflux nephropahy. A 5-month-old female initially was transferred for poor weight gain for 2 mo...
