Objectives: Congenital hypothyroidism (CH) is the most common neonatal endocrine disorder in infancy. The aim of this study was to screen for reported gene mutations among CH patients in our hospital and to illustrate a genetic mutation spectrum of CH in China.Methods: We designed a gene panel consisting of more than 20 relevant genes including TSHR and DUOX2. Blood samples were collected from 60 CH patients and their parents in Children’s Hospital ...

Background: Micropenis may result from different aetiology and therapy data are still scarce.Objective and hypotheses: To investigate the effect and safety of dihydrotestosterone transdermal gel in children with micropenis.Method: Totally 23 agnogenic micropenis children with 46,XY karyotype were recruited to participate a perspective study. SRY, AR and SRD5A2 gene were sequenced. 2.5% DHT gel was applied individually based on the ...

Background: Prader–Willi syndrome (PWS) is a genomic imprinting disorder due to loss of paternally expressed genes in the 15q11–q13 region and characterized by hypotonia, a poor suck, hypogonadism, GH deficiency(GHD), learning and behavioural problems. GH acts as a ligand for the GH receptor (GHR) coded by a gene polymorphism for an exon-s deletion (d3) seen in about 50% of Caucasians and associated with an increased response to GH (GH) therapy.<p class="abstext"...

Background: Hypotonia–Cystinuria syndrome (HCS), characterized by hypotonia at birth, poor feeding and growth retardation is an autosomal recessive disorder caused by homozygous microdeletions of PREPL and SCL3A genes. Increase in the urinary amino acids including cystine, lysine, arginine, and ornithine is the main laboratory finding.Objective and hypotheses: HCS was described in 17 patients so far and previous reports with favorable responses to G...

Background: Prader–Willi syndrome (PWS) is a rare genetic disorder associated with hyperphagia, and excessive weight gain. Patients with PWS are at elevated risk of developing morbid obesity and associated life-threatening complications. Although gut microbiota has been suggested to play a role in disease phenotypes, little is known about its composition and how it relates to hyperphagia.Objective: The aim of this ...

The majority of causes of gynecomastia in children and adolescents are physiologic but if it occurs outside the neonatal and pubertal period or persists after age 17 year, pathologic causes should be considered. A 17 year-old man presented with a 7-month history of breast enlargement without nipple discharge. He was born at 3300 grams. He hadn't any history of chronic disease and medication use. His parents were consangineous more distant than third degree. There was no f...

Background: Late-onset ornithine transcarbamylase deficiency (OTCD) is a clinical challenge due to its nonspecific symptoms and the potential for delayed treatment. Hyperammonemia caused by acute metabolism disorder leads to life-threatening encephalopathy. We presented a unique case of OTCD initially manifesting with hyperthyroidism, resulting in refractory hyperammonemia.Case report: A previously healthy 14-year-old Ch...

Background: Precocious puberty is common in boys occasionally in girls with beta human chorionic gonadotropin (β-hCG)-secreting intracranial tumors, and is reported to be peripheral precocious puberty exclusively.Object: To described a girl with intracranial β-hCG-secreting germ cell tumor（GCT） who presented with central precocious puberty（CPP）.Method:<...

Introduction: Rabson-Mendenhall Syndrome (RMS) is an autosomal recessive, extremely rare, serious insulin resistance syndrome that occurs as a result of mutation in the insulin receptor (INSR) gene. Pathogenic variants in the INSR gene cause a broad spectrum of inherited insulin resistance syndromes. Here, a male case who presented with the complaint of diffuse acanthosis nigricans and was diagnosed with RMS is shared. Case Repor...

Aim: This study aimed to compare the levels of appetite-regulating hormones (ghrelin, leptin, peptide-YY (PYY), neuropeptide-Y (NPY)) in girls with idiopathic central precocious puberty (ICPP) before treatment with prepubertal girls, and to evaluate changes in these hormone levels and body composition during leuprolide acetate (LA) treatment.Methods: This prospective, cross-sectional study included girls with ICPP, isola...
