Background and Aims: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by impaired cortisol synthesis. 21-hydroxylase deficiency (21-OHD) caused by mutations in CYP21A2 gene is the most common form of CAH. This study aims to analyze the phenotype-genotype correlation and the characteristics of gene mutation frequency of 21-OHD patients in China, helping to provide evidence for clinical practice and genetic counseling of 21-OHD patie...

Case description: A 14-year old boy with autoimmune hepatitis who was on long term oral steroids for 10 years, presented with acute onset lower back pain without preceding trauma. Lumbar spine radiograph showed severe osteopenia and compression fractures of vertebrae T12 to L1. Bone mineral density T-score at the lumbar region was −4.9. Biochemically, there was hypocalcaemia and severe hypophosphataemia with adjusted calcium 2.03 (2.20–2.65) mmol/l and phosphate 0.8...

Background: In newborns, physiological transition of glucose metabolism is typically completed within 48–72 h of life, yet prolonged hyperinsulinemic hypoglycemia (HH) beyond 5d of life is not uncommonly encountered, especially in infants at-risk of hypoglycemia. Management includes intravenous dextrose while awaiting spontaneous resolution (SR) of HH or Diazoxide (DZX) therapy. Since DZX acts by suppressing insulin release, concerns arise whether weight gain in infancy w...

Objective: To research the the relationship between secular trends of puberty development and obesity in child and adolescent in area of southwest China.Methods: Selected respectively 4010 childs and adolescents aged between 6 and 17 years in April 2003 to May 2005, and 1387 childs and adolescents aged between 6 and 18 years in December 2013 to November 2015 in China Chongqing area.Height, weight and the breast, pubic hair development of girls, and the t...

Background: 5α-reductase type 2 deficiency is a rare autosomal recessive hereditary disease. SRD5A2 gene defects lead to dysfunction of 5α-reductase type 2, that impair the conversion of testosterone to dihydrotestosterone and cause clinical features.Objective and hypotheses: To analyze the clinical manifestations and gene mutations of 5α-reductase type 2 deficiency in childhood.Method: The clinical features, laborat...

Background: Accumulated evidence indicates that the GH-IGF-1 pathway might be one of the crucial mechanisms of ISS. Insulin-like growth factor-1 receptor (IGF-1R) is the effector molecule that regulates the cascade reaction of hormone receptors in the GH–IGF-1 axis.Objective and hypotheses: To investigate the role of IGF-1R gene polymorphisms with regard to susceptibility to Idiopathic short stature risk in the Chinese population of Jiangxi area.</p...

Background: Rathke’s cleft cyst (RCC) has been reported rarely in children and adolescents. The occurrence of RCC with hypoplastic anterior pituitary can be explained by their common embryologic origin. However, the effects and sfety of recombinant human GH (rhGH) in GH deficient (GHD) children with RCC has not been previously reported.Objective and hypotheses: To assess the effects and safety of recombinant human GH (rhGH) in GH deficient (GHD) chi...

Background: Prader-Willi syndrome (PWS) is a complex genetic disorder caused by lack of expression of paternally inherited imprinted genes on Chr15q11-q13. rhGH has beneficial effects on growth, body composition and development. Starting age, dose titration and monitoring remain controversial.Objective: To study retrospectively children who presented in our multidisciplinary PWS clinic and assess response to rhGH treatment, auxology, IGF1 concentration a...

Background: Costello syndrome is a rare congenital disorder with characteristic findings involving multiple organ systems. The Costello Syndrome Family Network estimates that the birth prevalence in the United Kingdom is at least 1/500,000. So far, there has been only one affected individual reported in China.Objective and hypotheses: Diagnose the case of autosomal dominant Costello syndrome by direct squencing of HRAS gene. Analyze the correlation betwe...

Objective: This paper is aimed to explore the significance of plasma kisspeptin level in diagnosis and therapeutic evaluation through the detection of kisspeption level of girls diagnosed with idiopathic central precocious puberty (ICPP) before treatment and after 6-months of treatment and girls with simple premature thelarche (PT).Methods: A total of 70 girls including 24 girls diagnosed with ICPP, 21 girls with PT and 25 normal girls were enrolled. ELI...
