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...

Objectives: To describe the characteristics of central precocious puberty in patients at Children’s Hospital 2, Vietnam from 1/2010 to 12/2016.Method: Cross – sectional analysis.Results: There were 504 cases of central precocious puberty. The mean age was 7.6±1.4 years old; most of them were females (females/males: 71/1). The rate of overweight or obesity was 52.4%, accelerated height was recorded in 64.2%. The most ...

Background: A 3-year-old boy appeared healthy at birth and did not experience any fractures until 12 months of age. Blue sclera, frequent fractures without adequate trauma, nearly normal stature, the absence of dentinogenesis imperfecta, no bony deformity, and no limitation of mobility were characteristics suggestive of OI type I that were observed in the patient. The patient’s mother had blue sclera and a history of frequent fracture episodes until the age of 15 years.</...

Objective and hypotheses: To evaluate the long-term efficacy of triptorelin 3.75 mg subcutaneously injection every 6 weeks on final height in girls with ICPP.Method: Forty females with ICPP received triptorelin 3.75 mg every 6 weeks subcutaneously injection and reached FAH were collected. These patients were divided into two groups. Group A: GnRHa alone, n=17; group B: triptorelin+rhGH, n=23. During the treatment, height, weight, annual...

Background: Local oestrogen production in the brain regulates critical functions including neuronal development, gonadotropin secretion and sexual behaviour. In the mouse brain, a 36 kb distal promoter (l.f) regulates the Cyp19a1 gene that encodes aromatase, the key enzyme for oestrogen biosynthesis. In vitro, promoter l.f interacts with oestrogen receptor alpha (Esr1) and Progesterone receptor (Pgr) to mediate Cyp19a1 mRNA expressi...

Introduction: 45,X/46,XY mosaicism is a rare sex chromosome abnormality. The aim of this study is to provide outcomes, namely growth, comorbidities and gonadal function in patients with 45,X/46,XY mosaicism.Methods: This was a retrospective, longitudinal study conducted from January 2006 to January 2021 at a tertiary pediatric endocrine referral center. Patients' clinical presentation, karyotypes, height, hormonal profiles, imaging and histologic fi...

Introduction: Pseudohypoparathyroidism (PHP) is a group of heterogenous disorders characterized by end organ resistance to parathyroid hormone (PTH) action. In 1942, Fuller Albright first described the phenotype of Albright Hereditary Osteodystrophy (AHO) associated with end organ hormone resistance (brachydactyly, rounded face, short stature, central obesity, subcutaneous ossifications, and variable degrees of mental retardation). Recently EuroPHP network pro...

Maturity onset diabetes of the young (MODY) is a clinically heterogeneous disorder characterized by noninsulin-dependent diabetes diagnosed at a young age (<25 years) with autosomal dominant transmission and absence of pancreatic autoantibodies. Due to the relatively low prevalence in the general population and atypical clinical manifestations, MODY is often misdiagnosed with type 1 diabetes and type 2 diabetes. Currently, distinguishing MODY from type 1 and type 2 diabete...

Purpose: Our previous study showed no correlation between -202 A/C IGFBP-3 promoter polymorphism and Δheight SDS in children with growth hormone deficiency. We investigated the influences of the -202 IGFBP-3 polymorphism on 1-year follow-up outcomes of GH treatment in Korean children with ISS.Methods: Data was obtained from 81 children with idiopathic short stature (peak serum growth hormone (GH) ≥ 7.0 ng/mL b...

Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. In Korea, the prevalence of VDD was 47% in teenage boys and 65% in teenage girls. However, the optimal dosage regimen for correcting deficiency is unknown. We investigate the change of serum 25(OH) vitamin D concentration according to the treatment dosage and duration in VDD.Methods...
