Background & objective: The occurrence of CPP seems to be increasing in our clinical practice thesedays. It is known that CPP causes socio-psychological disturbances relating to early pubertal changes and finally leads to a significant decrease in the final adult height because of premature closure of the growth plate. This study was conducted to see major factors affecting to the bone maturation, which is closely related to the final adult height in girls with CPP.<p ...

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...

Background: As the human genome is further explored, multiple genetic anomalies at different loci are being found that confer varying degrees of predisposition to diabetes. MODY is the most common form of monogenic diabetes, accounting 2–5 percent of diabetes. Recently, we have found and reported three noble gene variants relating to MODY in Korean children (Shim et al, Horm Res Pediatr, 2015).Objective and hypotheses: This study was done to see the...

Background: ALT-P1 (CJ-40002) is a long-acting recombinant growth hormone (GH) fused with NexP, which is a long-acting carrier developed by Alteogen Inc. NexP is a protein engineered recombinant alpha1 antitrypsin with further increased in vivo half-life without a native proteinase inhibitor activity. In non-clinical studies of cynomologus monkeys, the extended half-life of hGH-NexP has been successfully proved without side effects in high dose as 20 mg per kg dose.<p clas...

Background: Premature thelarche (PT) is a benign, non-progressive condition defined as isolated breast development without the activation of the hypothalamic-pituitary axis. While the pathophysiology of PT remains unclear, increased sensitivity to estrogen may cause PT.Objective and hypotheses: The aim of this study was to investigate the association between polymorphisms in the estrogen receptor alpha (ERα) gene and PT in girls.<p class="abstex...

Background: Congenital hypothyroidism (CH) is the one of the most common preventable cause of mental retardation. Earlier and proper treatment is associated with better intellectual outcomes.Objective and hypotheses: The aim of the present study was to evaluate intellectual outcome of children with diagnosed congenital hypothyroidism (CH) and early onset treatment.Method: We retrospectively reviewed the medical record of 43 childre...

Context: It has recently been shown that mutations of MKRN3, the gene encoding makorin RING-finger protein 3, lead to central precocious puberty (CPP). The aim of this study was to investigate mutations of the MKRN3 gene in Korean girls with CPP.Methods: Two hundred and sixty Korean girls with idiopathic CPP were included in this study. Auxological and endocrine parameters were measured. The entire MKRN3 gene was directly seque...

Objective: Obesity is associated with bone age (BA) advancement of unclear etiology. In animal study, insulin may directly modulate skeletal growth. Our objective was to investigate the association with BA maturation and insulin levels in children with overweight and obesity.Methods: In this cross-sectional study of 42 prepubertal children, anthropometric data and hormonal values during oral glucose tolerance test were measured. Subjects were divided int...

Background: Hyperinsulinism/hyperammonemia (HI/HA) syndrome is a form of congenital hyperinsulinism (CHI) caused by a mutation in the GLUD1 gene. It is characterized by hyperinsulinemic hypoglycemia accompanying hyperammonemia.Objective and hypotheses: We report HI/HA syndrome with a 4-month-old male who hypoglycemic seizure.Method: A 4-month-old male infant presented with seizure caused by fasting-induced hypoglycemia. At the time...

Background: GnRH agonist (GnRHa) are able to modify natural course of Central Precocious Puberty (CPP) in girls.Objective and hypotheses: We evaluated the etiology and the effect of GnRHa in Korean CPP boys.Method: Total 29 boys diagnosed for CPP from 2007 to 2012 were included in Ajou University Medical Center. Sellar MRI was performed in 26 of 29 patients (89.7%). CPP was diagnosed on the basis of i) onset evidence of testicular ...
