Abstract: Background: Makorin ring finger protein 3 (MKRN3) is most common genetic cause of central precocious puberty (CPP) and associated with the initiation of puberty. Although its actual function is veiled. Recent study reported MKRN3 interacted with and suppressed neural pentraxin-1 precursor (NPTX1) activity via polyubiquitination during early puberty in mice.Objective: The aim of this study was t...

Neonatal thyrotoxicosis is rare and most of the cases are secondary to maternal Graves’ disease. It is usually transient, but can be associated with significant morbidity and mortality if not recognized promptly and treated adequately. We report a case of a 20-day-old female infant who developed thyrotoxicosis with irritability, tachycardia, and relatively poor weight gain. She was born to a mother who took levothyroxine during pregnancy after undergoing a thyroidectomy ...

Introduction: Hypophosphatasia (HPP) is a rare autosomal recessive or dominant genetic disorder characterized by the abnormal development of bones and teeth and deficiency of tissue non-specific alkaline phosphatase activity. These abnormalities occur due to defective mineralization, the process by which bones and teeth take up minerals such as calcium and phosphorus. The specific symptoms can vary greatly from one person to another, sometimes even among membe...

Purpose: Small for gestational age(SGA)babies at increased risk of growth retardation. This is very important issues for them but lacks attention. So we hope this study deserves better guidance. The objectives of this paper is to illustrate the importance of this critical issues and to outline growth prognosis at the beginning of adolescence of female and male babies born small for gestational age(SGA) in comparision to controls born appropriate for gestationa...

Background: Islet autoantibodies such as Glutamic Acid Decarboxylase (GAD), Islet antigen-2 (IA-2), Zinc Transporter 8 (ZnT8), and Insulin autoantibody (IAA) are known to be detected at higher frequencies in pediatric patients clinically diagnosed with type 2 diabetes than in adults. Therefore, it is crucial to evaluate them for accurate diagnosis, prognosis, and treatment direction. However, guidelines for when to re-evaluate patients with negative islet auto...

Gonadotropin-releasing hormone (GnRH) stimulation test is the gold standard test for diagnosing central precocious puberty (CPP), which needs time and effort to perform. Recently, many studies confirmed that Insulin-like growth factor-1 (IGF-1) is involved in the initiation and progression of puberty. With this inspection, we assumed that the IGF-1 level might be correlated with the pubertal stage in central precocious puberty. This study aimed to investigate the value of IGF-...

The girl was born full-term vaginally with birth weight 3.380kg. She had stayed in neonatal unit for 3 days for neonatal fever. Physical examination was unremarkable. She had normal-looking female external genitalia. She was discharged after a negative infection screen.She presented again at the age of 11 years with hoarseness of voice. Physical examination revealed normal growth and blood pressure. She had hoarseness of voice with mild laryngeal promine...

Turner syndrome(TS) is a chromosomal disorder which occurs in 1/2500 - 1/3000 among female live births, characterized by short stature, pubertal failure and cardiac defects. Mosaicism of 45X/47XXX is extremely rare and accounts for 1.7% of the TS cases. TS with 45X/47XXX is more likely to have spontaneous puberty. The case we present herein is a 13-years old girl who was admitted to Chuncheon sacred heart hospital due to severe anemia. She was diagnosed with Turner syndrom...

Background/aim: Anti – Müllerian hormone (AMH) and Inhibin B (INHB) are considered as possible biomarker of central precocious puberty(CPP). This study investigated serum AMH and INHB level in central precocious puberty andanalyzed clinical factors associated with these two hormone levels.Methods: In total, 48 girls with CPP and 35 age – matched prepubertal girls were enrolled in the study. The subjects were divided into two groups as CPP ...

Background: Experimental models suggest that exposure to low dose nonylphenol could induce adiposity and promote adipocyte differentiation in mice. However, studies on the effect of nonylphenol exposure to human obesity have not been adequately studied.Objective: We investigated the associations of serum nonylphenol concentration with adiposity measures in Korean children and adolescents.Me...
