Introduction: Primary polydipsia is rare during adolescence and is known to be associated with psychiatric disorders or psychological stress. Differential diagnosis includes endocrine, neurologic, renal, and iatrogenic causes.Case Report: A 14-year-old male presented with polydipsia and polyuria that persisted for 6 years. His fluid intake was about 9 liters a day and he woke up for voiding once or two times every night....

Background: Congenital hyperthyroidism is a rare disease. In most patients with congenital hyperthyroidism are autoimmune forms caused by maternal thyroid-stimulating antibodies. In contrast to autoimmune hyperthyroidism that is transient, nonautoimmune form of congenital hyperthyroidism is persistent and results from activating germline mutations in the thyrotropin receptor (TSHR) gene.Case presentation: We report the case of a Korean male infant with s...

Objective: We try to investigate the polymorphisms and amino acid variants of HLA-A, -B, -C, -DRB1, -DQB1, -DPB1 molecules in early-onset AITD.Methods: The genotypes of HLA-A, B, C, DRB1, DQB1, and DPB1 on AITD were analyzed in 102 Korean children with AITDs (Graves’ disease (GD)=62, Hashimoto’s disease (HD)=40) and 142 healthy control using sequence-based typing. Analysis of variant amino acids was performed across the genotyping results with ...

Background: South Korea is one of the adequate or excessive iodine nutritional state countries and high-iodine intake is related to papillary thyroid cancer. The prevalence of thyroid cancer of South Korea has increased and the proportion of thyroid papillary cancer has increased as 97.9–98.3% in 2010. Childhood thyroid cancer is rare, and the prevalence of thyroid cancer in pediatric population was reported as 20–26% of thyroid nodules worldwide. However, there have...

Background: Hematopoietic stem cell transplantation (HSCT) recipients are at risk of endocrine complications as a result of chemotherapy and radiation therapy. Development of diabetes mellitus (DM) after HSCT is less frequently reported compared with other complications.Objective and hypotheses: We investigated clinical features of newly diagnosed DM after HSCT for treatment of childhood leukemia.Method: Between April 1999 and Marc...

Purpose: We try to analyze the prediction capacity of variable factors to diagnose adrenal insufficiency.Methods: We analyzed clinical and laboratory data of 22 children (Male =13) who have been checked regular dose ACTH stimulation test for suspected symptoms after HSCT (Lymphoid leukemia=5, Myeloid leukemia=9, Non-malignant=8) at the Catholic HSCT center from Feb 2013 to Feb 2017 at Seoul St. Mary’s Hospital. A normal response of ACTH stimulation ...

Purpose: To analyze the effects of clinical and laboratory factors, including insulin-like growth factor (IGF) levels, on the height velocity of normal prepubertal children.Methods: Ninety-five healthy prepubertal children (33 boys, 62 girls) were enrolled. The mean chronological age of the participants was 6.3±1.4 years, with a height standard deviation score (SDS) of −0.88±0.70. IGF-1, IGF binding protein-3 (IGFBP-3), SDS for anthropome...

Background: Hematopoietic stem cell transplantation (HSCT) has improved the prognosis of children with malignant hematologic disease. However, it has had significant adverse effects on the endocrine system, including bone health. Limited studies are available to assess osteoporosis in survivors of adolescents after HSCT.Objective and hypotheses: We investigate the bone mineral density (BMD) and endocrinopathy/treatment factors associated with low BMD in ...

Background: Central precocious puberty (CPP) may result from organic lesions, but it is most frequently of idiopathic origin in girls.Objective and hypotheses: The objective of the study was to identify central nervous system abnormalities in girls with CPP.Method: This retrospective study was performed in 3-tertiary care hospitals between 2005 and 2015. During this period, 200 girls with CPP performed brain magnetic resonance imag...

Background: The Toll-like receptors (TLRs) are germline-encoded receptors that play an essential role in initiating the immune response against pathogens.Objective and hypotheses: In this study, we assess the association of TLR polymorphism with autoimmune thyroid disease (AITD) in Korean children.Method: Seven Toll-like receptor genes (TLR-1, -2, -3, -4, -5, -6, -9) including 15 single-nucleotide polymor...
