Background: Risk of developing germ cell tumors (GCTs) in disorders of sex development (DSD) patients with karyotypes contain Y-chromosome or it’s material (Y) increase with age. The appropriate timing for prophylactic gonadectomy in these patients is still controversial.Aim: To analyze the gonadal tumor incidence and histological assessment of gonads in DSD (Y) patients who were treated in a single institution between 1997 and 03/2018.<p class=...

Background: CYP27B1 converts 25-hydroxyvitamin D3 to active 1,25-dihydroxyvitamin D3, playing a vital role in calcium homeostasis and bone growth. Vitamin D-dependent rickets type 1 (VDDR-1) is a rare autosomal recessive disorder caused by mutations in CYP27B1.Objective and hypotheses: Enzymatic and structural analysis of mutations in a patient with calcipenic rickets.Method: Two siblings presented with calcip...

Aldosterone synthase deficiency (ASD) is a rare autosomal recessive disease caused by inactivating mutation in the CYP11B2 gene, usually presenting with severe salt-wasting in infancy or stress-induced hyperkalaemia and postural hypotension in adulthood. ASD is unable to be detected by Neonatal screening of 17-hydroxyprogesterone, hence patients would not be diagnosed until they suffer from salt-wasting crisis. Due to this potentially life-threatening risk, early detection and...

Objective: To assess the serum levels of IL-6, TNF-a and Omentin-1 in girls with Turner Syndrome (TS) and to analyze their association with FPG, FINS, TC, TG, HDL-c, LDL-c, and BMISDS.Methods: In total of 33 TS girls aged (12.8±3.9) yr and 33 age-matched normal girls aged (12.6±3.7) yr were recruited in the study. Height (Ht) and Weight (Wt) were measured; FPG, FINS, TC, TG, HDL-c, LDL-c, IGF-1 and E2 were also measured; BMI and BMISDS were cal...

Background: Patients with 46,XY, DSD are characterized by ambiguous or female external genitalia, caused by incomplete intrauterine masculinization. 5α-reductase type 2 deficiency due to SRD5A2 gene mutations result in inadequate conversion from testosterone to dihydrotestosterone (DHT), and is responsible for incomplete virilization in male patients. Up to date, more than 50 mutations have been reported, however, clinical features are variable and heterogeneous.<p cl...

Background: Ovarian adrenal rest tumors (OART) is a rare complication of congenital adrenal hyperplasia (CAH) and is not very well characterized yet.Objective and hypotheses: We report four cases of OART in Chinese girls with CAH due to 21-hydroxylase deficiency (21 OHD).Method: We describe the clinical, imaging, and surgical findings of the patients.Results: The four cases of CAH with OART included three sal...

Background: In the past years, new glucometers with integrated automated bolus calculator, are available in the market for patients whith type 1 diabetes (DM1) in multiple daily injections (MDI) therapy. The limited bibliography about the use of these meters in the pediatric population with DM1, suggests that it may have beneficial effects in terms of glycaemic control and improved quality of life.Objective and hypotheses: The use of a glucometer with an...

Background: Management of transient neonatal diabetes mellitus is complex. Conventional insulin therapy may be increase additional medical problems. From the case is presented, We suggested s.c. insulin pump therapy of neonatal diabetes is a safe and effective approach to management.Objective and hypotheses: To evaluate the therapeutic effect of continuous s.c. insulin infusion with insulin pump in a case with transient neonatal diabetes mellitus (TNDM)....

Objective: We assessed in a retrospective unicenter study the effect on menstrual regularity of early menarche and treatment with GnRH analogs (GnRHa) in central precocious puberty (CPP) or early and fast puberty (EFP) girls.Methods: Six hundred and ten healthy girls were interviewed and their menarche age and menstrual interval were recorded. One hundred and sixty-nine CPP or EFP girls who were treated with GnRHa were fellowed up, and their menarche age...

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...
