Impact of Different Doses of Bisphenol-A on the Puberty of Female Rats

Linqi Chen , Fan Yang , Meifang Jin

Objective: To observe vaginal opening day (VOD), hypothalamic kiss-1 gene and ovarian estrogen receptors (ER) gene expression level changes in neonatal rats exposure to different doses of bisphenol-A(BPA).Methods: Neonatal female SD rats were randomly divided into six groups: control group, vehicle group, 17β-estradiol group (17β-estradiol, E2,10 μg/kg per day), low-dose BPA group (25 μg/kg per day), medium-dose BPA group (50 μg/...

Impact of Bisphenol-A on the Puberty of Female Rats

Linqi Chen , Fan Yang , Meifang Jin , Haiying Wu

Background: It is now widely accepted that chemical pollutants in the environment can interfere with the endocrine system. The impact of endocrine disrupting chemicals on puberty disorders is concerned. bisphenol-A (BPA) has been measured in fetal plasma. There are different toxic effects with different doses of BPA.Objective and hypotheses: To observe vaginal opening day (VOD) hypothalamic kiss-1 gene and ovarian estrogen receptors (ER) gene expression ...

TBG Excess as a Cause of Hyperthyroxinemia and High T3 Detected Incidentally or Through Neonatal Screening Test

Jin Hye Young

Inherited thyroxine binding globulin (TBG) disorder can be identified incidentally or through neonatal screening test. TBG excess is characterized by high levels of thyroxine (T4) but normal level of free T4 (fT4), while TBG deficiency presents with low T4 levels and normal fT4 levels. TBG excess is caused by TBG gene duplication or triplication. A 27 day old newborn was brought to the hospital because of hyperthyroxinemia that was identified through neonatal screenin...

Hypercalcemia Associated with Increased Parathyroid Hormone-related Protein (PTHrP) in a Patient with Medulloblastoma Successfully Treated with Pamidronate

Kang Seok Jin , Kim Heung Sik

We report a patient with medulloblastoma showing severe hypercalcemia and a raised PTHrP serum level. He was a 19-year-old with a history of recurrent medulloblastoma. He developed constipation, lethargy and altered mentality for 3 weeks. There was no family history of hypercalcemia. Laboratory test revealed hypercalcemia of 18.2 mg/dL. PTHrP increased to 10.7 pmol/L (normal range: <1.1 pmol/L), whereas serum level of intact parathyroid hormone was suppressed to 5 pg/mL (n...

Molecular Defects Identified by Whole Exome Sequencing in a Chinese Boy with Fructose-1,6-Bisphosphatase Deficiency

Huang Zhuo , Wu Jin , Xiang Chengfa

Backgroud: Fructose-1,6-bisphosphatase (FBPase) deficiency is a rare autosomal recessive inherited disorder of gluconeogenesis, which caused by the mutations in the FBP1 gene. FBPase deficiency is characterized by recurrent episodes of hypoglycemia with metabolic and lactic acidosis. If diagnosed early, the prognosis of this disorder is excellent by the prevention of hypoglycemia and avoidance of intake of fructose and sucrose. However, the misdiagnosis of FBPase defi...

Growth Outcome in Girls with Idiopathic Central Precocious Puberty Treated with Gonadotropin-releasing Hormone Agonist

Sang Lee Hae , Hwang Jin Soon

Objective: Gonadotropin-releasing hormone agonists (GnRHa) are the treatment of choice for central precocious puberty (CPP) and have been widely used for decades. We determined the effect of GnRHa treatment on auxological outcomes of girls with idiopathic CPP.Methods: This study included 84 girls treated monthly with depot leuprolide acetate who had reached adult height. We compared their final adult height (FAH) with their initial predicted adult height...

Earlier Mother’s Age at Menarche is a Risk Factor of Daughter’s Early Menarche and Short Stature in Young Korean Female: Epidemiologic Study

Lim Jung Sub , Hwang Jin Soon

Objective: To investigate whether earlier mother’s age at menarche is a risk factor of daughter’s early menarche, obesity, and short stature in young Korean female.Research design and methods: We tested associations between mother’s age at menarche, mother’s adult body size and her daughter’s age at menarche, body size from the data of 6th Korea National Health and Nutrition Examination Survey (KNHANES VI) (2013–2015). We an...

Whole-exome Sequencing Identifies Novel Pathogenic Variants in Korean Families with Central Precocious Puberty

Lee Hae Sang , Hwang Jin Soon

Objective: Central precocious puberty (CPP) is characterized by the development of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys. Early activation of hypothalamic-gonadal axis is influenced by both environmental and genetic factors. Especially, genetic factors have critical role of pubertal progression, but mutations associated with CPP have only been discovered in three genes: KISS1, KISS1R, and MKRN3. The aim of thi...

Birth Anthropometry with Cord Blood Insulin-Like Growth Factor 1 and Leptin in Korean Appropriate-For-Gestational-Age Infants Born at ≥28 Weeks' Gestation

Kang Seok Jin , Kim Se Jin , Lee Ga Hyun , Kim Heung Sik

Background: We investigated the relationship of birth anthropometry with cord blood insulin-like growth factor 1 (IGF-1) and leptin levels in Korean infants born at ≥28 weeks' gestation.Methods: One hundred five appropriate-for-gestational-age (AGA) infants, defined as infants with birth weights (BWs) between the 10th and 90th percentiles for gestational age, were enrolled. Enrolled infants were stratified into...

Association Between Nonalcoholic Fatty Liver Disease and Growth Hormone Deficiency in Patients with Childhood-Onset Hypopituitarism

Kim Se Jin , Kim Heung Sik , Lee Ga Hyun , Kang Seok Jin

Background & Aims: Although, there has been reports demonstrating association between adult-onset hypopituitarism and development of nonalcoholic fatty liver disease (NAFLD), studies are lacking regarding the development of NAFLD in children and young adult with childhood-onset hypopituitarism. We aimed to identify association between NAFLD and hypopituitarism in these patients.Methods: 76 Korean children and young a...
