Background: Percutaneous administration of dihydrotestosterone (DHT) gel has been successful used in promoting phallic growth in children with micropenis. We investigated whether percutaneous administration of DHT gel is similarly effective in Chinese children with microphallus due to various etiologies.Objective and hypotheses: To study the pharmacokinetics and effect of percutaneous administration DHT gel in the Chinese microphallus patients.<p cla...

Background: The hypothalamus-pituitary-gonad (HPG) axis is crutial to the development and function of reproductive system. Gonadotropin-releasing hormone (GnRH) has been the standard test for the assessment of activation of HPG axis. Because GnRH is no longer available, GnRH analogues (GnRHa) are now used. In previous studies, GnRHa stimulation tests have been the mainstay for establishing the diagnosis of precocious puberty in female and distinguishing constitutional delay of...

Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is reported inadequate growth and impairment of the final height (FH).Objective: We present the results of near FH in 55 patients with classic 21-OHD followed up for approximately 11.6 years(the longest 25.3 years)in a single institution, and the variables related to NFH.Method: Patients with classic 21-OHD followed up at our clinic, who had ...

Background: Nephrotic syndrome is the most common cause of kidney disease in children, but its pathogenesis remains unclear. Nephrotic syndrome in patients with congenital adrenal hyperplasia has not been reported.Case presentation: A 38-month-old female child was admitted with eyelid edema. She was the first child (birth weight, 3.0 kg, full term) of non-consanguineous parents of Chinese Han ethnicit. She had been diagnosed with congenital adrenal hyper...

Background: Early menarche may be associated with diabetes, metabolic syndrome, cardiovascular disease and oligomenorrhoea in adults. While the state of metabolism and gonadal axis of early menarche girls and girls who treated with Gonadotropin-releasing hormone analogues (GnRHa) during puberty was not so clear.Objective and hypotheses: We assessed in a retrospective unicentre study the state of metabolism and gonadal axis of early menarche girls and gir...

Background: Congenital adrenal hyperplasia due to 17α-hydroxylase deficiency is a rare autosomal recessive disorder, characterized by sexual infantilism, amenorrhoea, hypertension and hypokalemia,which is caused by CYP17A1 gene mutations.Objective and hypotheses: To provide a descriptive analysis of 17α-hydroxylase deficiency in two female siblings with different karyotype of 46, XX and 46, XY.Method: The clinical feature...

Background: Oestrogen has positive effect to glucose and lipid metabolism. On the contrary, leptin has negative effect to metabolism. During GnRHa treatment, the secretion of oestrogen was suppressed and its effect will fade away.Objective and hypotheses: To observe the changes of body fat and metabolic parameters of central precocious puberty (CPP) or early and fast puberty (EFP) girls who treated with Gonadotropin-releasing hormone analogues (GnRHa).</...

Objective and hypotheses: To compare the different efficacies between recombinant human GH (rhGH) alone and rhGH combined with low does stanozolol on improving growth of the girls with Turner syndrome (TS).Method: TS girls were divided into two groups. Group 1 (15 cases) received rhGH therapy, aged (13.09±2.70) years, bone age (11.00±1.01) years, height was (131.46±8.22) cm. Group 2 (22 cases) received low does stanozolol combined with rhG...

Background: X-linked Adrenal Hypoplasia Congenita (AHC) is a very rare hereditary cause of pediatric primary adrenal insufficiency (PAI). Congenital adrenal hyperplasia (CAH) due to 21-hydrolase deficiency(21OHD) is most common hereditary cause of pediatric PAI with autodominal recessive inheritance.Objective: To present a Chinese boy with PAI with the pathogenic mutation of NROB1 and Double mutants in cis of CYP21A2 gen...

Objective: To summarize the metabolic status in children with classic congenital adrenal hyperplasia(CAH) due to 21-hydroxylase deficiency (21OHD).Methods: Children with classic 21OHD from Pediatric Endocrinology Clinics at the First affiliated hospital of Sun Yat-Sen University from January 1990 to February 2023 were included in the study. The prevalence of overweight/obesity, dyslipidemia [high triglyceride (TG), high ...
