Background: Gynecomastia develops due to the reversed estradiol-to-Testosterone ratio in adolescence, and symptoms typically improve within two years. The causes vary widely, including estrogen excess and tumors, and surgical treatment is usually given in late adolescence because postoperative symptoms may recur in adolescents. There are no guiding recommendations for gynecomastia to date besides the suggestion to consider rapidly growing gynecomastia and brea...

Bacground and objective: Idiopathic infantile hypercalcemia is one of rare diseases characterizing hypercalcemia in infancy. Renal phosphate absorption in proximal tubules plays a very important role in the phosphate and calcium homeostasis. SLC34A1 is known a key regulator of renal phosphate reabsorption. SLC34A1 gene mutation is one of very uncommon causes of idiopathic infantile hypercalcemia. We have experienced a case of idiopathic infantile hypercalcemia caused by a homo...

Background & objective: Maturity-onset diabetes of the young (MODY) is a monogenic form of diabetes that is characterized by an early onset, autosomal dominant mode of inheritance and a primary defect in pancreatic β-cell function. MODY has been identified in Asian populations, however, there is a big discrepancy in the genetic locus between Asian and Caucasian patients with MODY. We previously reported that mutations in PTPRD, SYT9 and WFS1 have been identified in Ko...

Background and objective: It has been reported that glycemic control gets better in children with T1DM on insulin glargine and lispro when compard to patients on NPH and RI. This study was conducted to see the changes of glycemic control after switching from insulin glargine and lispro (GLAR/LIS) to NPH and RI (NPH/RI) in Korean children with T1DM.Materials and methods: We studied 14 patients who were diagnosed with T1DM in Kyungpook National Children&#1...

Background and objectives: A positive association between birth weight and BMI among children and adolescents has been shown in many populations. Several studies have indicated that breastfed children have lower risk of childhood obesity. Therefore, the aim of this study was to investigate the BMI trajectory according to birth weight status and protective effect of breastfeeding on overweight/obesity prevalence in children 6 years of age.Methods: A retro...

Background: Humans are exposed to a variety of endocrine disruptors (EDs), including phthalates and phenol substitutes, in daily life. Previous studies have suggested the association between individual EDs and the risk of obesity, however, studies on the effects of multiple EDs have been extremely limited. We investigated the associations of urinary 12 phthalates, 3 polycyclic aromatic hydrocarbons, and 26 phenol substitutes with adiposity measures in Korean girls.<p class...

Background and objective: The peak GH value plays a crucial role in the diagnosis of idiopathic growth hormone deficiency (iGHD). However, the prediction of peak GH in iGHD diagnosis is known to be limited. The purpose of this study was to evaluate the clinical and diagnostic usefulness of the total sum of GH values obtained from the GH stimulation test.Materials and methods: We retrospectively reviewed 178 prepubertal children who were diagnosed with iG...

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...
