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 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 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 ...

Background: Noonan syndrome is autosomal dominantly inherited disease with an incidence of 1:1000 to 1:2500 newborns. It is caused by different gene mutations involved in the RAS/MAP kinase signaling pathway in the cells. Phenotype including expression of dysmorphic features and visceral organ affection is variable. Different gene mutations are found in approximately 60–70% of tested patients.Objective and hypotheses: To report mutational analysis i...

Objectives: We investigated the trajectories in hemoglobin A1C (A1C) levels among transition-aged patients (age from 15 to 22 years) with type 1 diabetes (T1D).Methods: Among the patients diagnosed with type 1 diabetes in pediatric age between 2001 and 2013 in Seoul National University Children’s Hospital, 119 patients (54 males and 65 females) with a diagnostic age for under 14 and measurement of A1C at least once...

Purpose: To investigate the overall prevalence of vertebral fractures (VF) following childhood acute lymphoblastic leukemia (ALL) treatment and examine the association of VF with growth trajectory and insulin-like growth factorsMethods: Children (n = 172; 59.3 % male) diagnosed with ALL at age between 2 and 18 years were assessed for VF by screening the lateral thoracolumbar spine radiographs (Genant’s semi-quantitative met...

Background: Hypertension is the leading cause of cardiovascular disease worldwide and both high and low blood pressures are associated with various chronic disease. Thyroid hormones have profound effects on cardiovascular function, including effects on blood pressure.Objective and hypotheses: Recent studies suggest that early life high blood pressure could be attributed to hypertension in late adulthood. Therefore, we aimed to investigate the association...

Purpose: We investigated the prevalence of subclinical hypothyroidism (SCH) and its risk factors in prepubertal children at age 6. We also evaluated the prevalence of thyroid nodule or cyst and its relationship with SCH in prepubertal children.Methods: From the Environment and Development of Children (EDC) cohort study, 458 prepubertal children (243 boys, mean 5.8 years) who visited at age 6 were included in this study. Serum concentrations of free thyro...

Background: Leptin has a major role in the metabolic gating of pubertal maturation. Kisspeptin is an essential gatekeeper of puberty. Neurokinin B (NK B) is not widely known in the precocious puberty (PP) but it is coexpressed with kisspeptin in the arcuate nucleus and synchronizes the pulsatile secretion of kisspeptin.Objective and hypotheses: Leptin, kisspeptin, and NK B are influenced by energy balance and metabolic status has a clear impact on the ti...
