This study aimed to compare cut-off points corrected for age and gender (CCOP) with fixed cut-off points (FCOP) for fasting plasma insulin and homeostasis model assessment-insulin resistance (HOMA-IR) for the diagnosis of IR in Korean obese children and adolescents and to identify IR applying CCOP and FCOP using as outcome the presence of dyslipidemia and Metabolic syndrome (MetS).We performed a cross sectional analysis of data from 195 adolescents aged ...

Purpose: The association between appendicular skeletal muscle mass (ASM) and cardiometabolic risk has been emphasized. We estimated reference values of the percentage of ASM (PASM) and investigated its association with metabolic syndrome (MS) in Korean adolescents.Methods: Data from Korea National Health and Nutrition Examination Survey performed between 2009 and 2011 was used. Tables and graphs of reference PASM were ge...

In children with X-linked hypophosphatemia (XLH), excess circulating fibroblast growth factor 23 (FGF23) causes hypophosphatemia with consequent rickets, skeletal deformities, and impairments in growth and mobility. Compared to continuation with conventional therapy (oral phosphate and active vitamin D [Pi/D]), switching to treatment with burosumab, a fully human monoclonal antibody against FGF23, showed significantly greater improvement in phosphate homeostasis, rickets sever...

In children with XLH, high circulating levels of FGF23 cause hypophosphatemia with consequent rickets, skeletal deformities, and growth impairment. Conventional therapy consists of multiple daily doses of oral phosphate and active vitamin D (Pi/D). Burosumab is a fully human monoclonal antibody against FGF23 indicated for the treatment of XLH. In the active-control study CL301 (NCT02915705), 61 children with XLH (1–12 years old) were randomized (1:1) to receive subcutaneo...

Introduction: Maturity-onset diabetes of the young (MODY) is a genetically heterogeneous group of monogenic endocrine disorders which is inherited as autosomal dominant pattern and characterized pancreatic β-cell dysfunction. It has been estimated to represent around 1% to 6% of all diabetes. The hallmark of MODY is that the onset is before 25 years of age and inherited in an autosomal dominant manner. Generally, there are several known genes that cause M...

Purpose: Metabolic syndrome (MetS) is a state of chronic inflammation, and high-sensitivity C-reactive protein (hsCRP) indicates inflammation. This paper evaluates the association between hsCRP and MetS and its components in Korean children and adolescents.Methods: We analyzed the data of 1,247 subjects (633 males, 14.2 ± 2.7 years) from the Korea National Health and Nutrition Examination Survey (KNHANES) 2016-2017. T...

Purpose: Recent reports indicate that being small for gestational age could be a risk factor for delayed thyroid stimulating hormone (TSH) elevation (dTSH) in preterm infants. Very few studies have investigated the development of delayed thyroid stimulating hormone elevation in small-for-gestational-age late-preterm infants with a gestational age of 34–36 weeks.Methods: We retrospectively included 70 small-for-gest...

Objectives: Hypophosphatasia (HP) is a rare inherited disorder characterized by defective bone and teeth mineralization, and deficiency of serum and bone alkaline phosphatase activity. The symptoms are highly variable in their clinical expression, which ranges from stillbirth without a mineralized bone to early loss of teeth without bone symptoms. We aimed to report a patient with HP presenting with fibrous dysplasia.Methods:</st...

Familial hypobetalipoproteinemia (FHBL) is an autosomal codominantly inherited disorder of lipid metabolism characterized by <5th percentile plasma levels of LDL cholesterol or total apolipoprotein B (apoB). LDL cholesterol level is usually between 20-50 mg/dL. FHBL results from mutations in APOB, PCSK9 gene. Patients with homozygous APOB-related familial hypobetalipoproteinemia (APOB-FHBL) may have symptoms of fat malabsorption, steatorrhea, diarrhea, failure to thrive, de...

1q21.1 recurrent microdeletion syndrome is a rare chromosomal disorder caused by a genetic abnormality of non-allelic homologous recombination in the sequence of flanking a copy number variation event during meiosis. The characteristic features of 1q21 microdeletion syndrome are dysmorphic facial appearances with microcephaly, and mild to moderate developmental delay of speech and motor, eye abnormality, short stature, skeletal malformation, and psychiatric and behavioral diso...
