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: It remains unclear whether specimen repeated freeze-thaw cycles can influence urinary lutenising hormone (LH) and follicular stimulating hormone (FSH) assayed by immunochemiluminometric assays (ICMA).Objective and hypotheses: To investigate the effect of specimen repeated freeze-thaw cycles on urinary LH and FSH determined by ICMA.Method: The first morning-voided urine was collected and divided two parts. One part was s...

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 ...

Background: CPP is commonly treated with triptorelin, a gonadotropin-releasing hormone (GnRH) analogue. It is available as 1-month and 3-month prolonged-release (PR) formulations, but only the former is approved for CPP in China. Overseas studies have proved the efficacy and safety of triptorelin 3-month PR formulation; this study evaluated efficacy and safety in Chinese children with CPP.Methods: In this 12-month, open-...

Background: Congenital sodium diarrhea (CSD) is a monogenic disorder caused by specific genetic defects that increase sodium content in the stool, resulting in intractable diarrhea. There are two categories of CSD depending on whether it involves other congenital malformations: non-syndromic congenital sodium loss diarrhea (non-sCSD) and syndromic congenital sodium loss diarrhea (sCSD). For non- sCSD, the identified causative genes include SLC9A3 and GUCY2C, w...

Introduction: Cushing's syndrome(CS) is rare in the pediatric population, and the cause vary with age. Primary pigmented nodular adrenocortical disease (PPNAD) is one of the causes of CS, though it is a rare disorder. It has been proposed that in children with CS, PPNAD should be suspected. Here we report a young boy with CS due to PPNAD associated with a somatic mutation of the PRKACA.Case Presentation: The child w...

Background: Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver disease in both children and adults; however, the exact pathogenesis of NAFLD remains obscure. Accumulating evidence supports the effects of miRNA in the lipid metabolism and the regulation of insulin resistance, providing a potential linkage between the miRNA and NAFLD.Objective and Hypotheses: The aims of this study were to explore microRNA (miRNA) expression profiles in NA...

Background: It is not yet clear whether the adult height (AH) is affected by the onset of puberty at 6 or 7 years old in girl in China.Objective and hypotheses: To evaluate AH in girl with the onset of puberty at 6 or 7 years old.Method: The standard of AH in girl was considered that their bone ages were equal to (or greater than) 15 years old or they were at least 3 years post-menarche. Eighty-two girls with the onset of puberty a...

Background: It remains unclear whether specimen pH can influence urinary LH and FSH assayed by immunochemiluminometric assays (ICMA).Objective and hypotheses: To investigate the effect of specimen pH on urinary LH and FSH assayed by ICMA.Method: The first morning-voided urine were collected and divided into 11 samples (each 100 ml). The urine pH was determined with a pH meter. Hydrochloric acid and sodium hydroxide were added to al...
