OBJECTIVES Dyslipidemia is one of the important modifiable risk factors for cardiovascular disease. Thus, to know the prevalence of dyslipidemia is the 1(st) step to make guidelines of screening and management plan. Although, American Academy of Pediatrics updated the guidelines for lipid in childhood, Asian study is rare. METHODS The authors aimed to(More)
OBJECTIVE Puberty is a period characterized by growth spurt and rapid change in body composition. The effect of GnRH agonist therapy for central precocious puberty on bone mineral density is unclear. We demonstrated changes in bone mineral density in subjects with central precocious puberty, who were treated with GnRH agonist for more than 3 years. DESIGN(More)
BACKGROUND AND AIM Serum alanine aminotransferase (ALT) is not only a surrogate marker of chronic liver disease but also predictive of future development of cardiovascular disease (CVD) in adults; however, pediatric reference data are rare, and "healthy-range ALT limits" have not been assessed to predict cardiovascular risk in children and adolescents.

Small for gestational age (SGA) at birth and postnatal growth pattern may have an impact on insulin resistance and body composition in their later life. Emerging evidence has indicated that insulin-like growth factor binding protein-2 (IGFBP-2) may be related to insulin sensitivity. The aim of this study was to evaluate insulin resistance and IGFBP-2 levels(More)
OBJECTIVE Excess adiposity may influence various aspects of pubertal development, including the timing of pubertal initiation and hormonal parameters during puberty. The aim of the study was to evaluate the impact of body mass index (BMI) on luteinizing hormone (LH) secretion to gonadotropin-releasing hormone (GnRH) stimulation test in boys with precocious(More)
PURPOSE Short stature is the most common finding in patients with Turner syndrome. Improving the final adult height in these patients is a challenge both for the patients and physicians. We investigated the clinical response of patients to growth hormone treatment for height improvement over the period of three years. METHODS Review of medical records(More)
BACKGROUND Turner syndrome is due to the absence of all or significant parts of one of the sex chromosomes in females. Turner syndrome is a common cause of ovarian failure, and hypergonadotropic hypogonadism occurs in virtually all affected individuals. One case of a variant Turner syndrome with precocious puberty is presented. CASE An eight-year-old girl(More)
HRV (heart rate variability) is one of the most promising quantitative indications of autonomic activity. In present study, our aim is to develop the multi-pararmetric feature including linear and nonlinear features of HRV. We also propose a suitable prediction model to enhance the reliability of medical examination for cardiovascular disease. This study(More)
