Background: Sex Cord Tumour with Annular tubules (SCTAT) is a rare ovarian benign tumour accounted approximately for 5% of ovarian tumour. SCTAT is an oestrogen producing ovarian tumour and can cause precocious puberty. For SCTAT, oophorectomy is recommended as the first-line therapy. Since SCTAT has a high rate of recurrence, it is clinically important to find a monitor method that can detect cancer recurrence in an early stage. In the previous reports, E2 and anti-mullerian ...

Background: Hyperinsulinemic androgen excess is the most common cause of hirsutism, acne, seborrhea and menstrual irregularity in adolescent girls. The ovarian androgen excess originates most often from an absolute or relative excess of fat (in adipose tissue and in organs such as the liver) and from the ensuing elevations in insulinaemia and gonadotropin secretion. There is no approved therapy for androgen excess in adolescent girls. The prime recommendation is to reduce body...

Background: The oestrogenic activity of endocrine-disrupting compounds (EDCs) has been reported to be associated with premature thelarche (PT) and precocious puberty. Some years ago, we developed a recombinant cell bioassay to determine serum estrogenic bioactivity (EBA) that is useful in physiology, as well as in the field of the environmental-related endocrine diseases. We recently improved the assay with an evaluation of EBA before and after incubation with estrogen recepto...

Background: Adolescent polycystic ovary syndrome (PCOS) may be difficult to distinguish from pubertal changes and diagnosis remains a challenge.Objective and hypotheses: To investigate the value of different biochemical parameters for the diagnosis of PCOS and also to assess the prevalence of non-classical congenital adrenal hyperplasia (NCCAH) among adolescent girls referred for clinical symptoms suggesting PCOS.Method: Retrospect...

Background: Gonadal or sexual dysfunctions are common and important complications of childhood cancer survivors. But few studies have been conducted on these areas, and if any, they are only about gonadal dysfunctions. Semen quality or sexual functions were rarely investigated.Objective and hypotheses: We purposed to evaluate prevalence of gonadal failure, semen abnormality, and sexual dysfunction of adolescent/young adult childhood cancer survivors. Ris...

Background: Specific measurement of low serum/plasma concentrations of 17β-oestradiol (E2) is important in pre-pubertal and pubertal children in routine paediatric endocrinology. The role of oestrone (E1) and oestriol (E3) is not as comprehensively well understood in different pediatric endocrine disease states. We describe a method for high sensitivity analysis of estradiol (E2), oestrone (E1) and oestriol (E3) using LC-MS/MS.Objective and hypothes...

Background: Prader-Willi syndrome (PWS), caused by loss of paternally imprinted genes in the 15q11-13 region, results in hypogonadism which is more severe in males.Objective: To review the gonadal status of patients seen in a dedicated PWS clinic from 1990–2013 inclusive so as to establish the clinical patterns and hence to optimise future management.Method: Retrospective case note review over a 23-year period.<p class="ab...

Background: 25–50% of paediatric patients with chronic endocrine diseases are lost for follow-up in adult care.Aims and objectives: A standardised medical and psychological work-up to identify disease specific morbidity and to comprehend quality of life in adolescents with chronic endocrine diseases at the time of transition from paediatric to adult care.Methods: The quality of life (DISABKIDS1 and KIDSCREEN2</...

Background: Androgen insensitivity syndrome in its complete form (CAIS) is a disorder of hormone resistance characterised by a female phenotype in an individual with an XY karyotype and testes producing age-appropriated normal concentrations of androgens. Pathogenesis is the result of mutations in the x-linked androgen receptor (AR) gene, which encodes for the ligand-activated AR. We report the clinical, biochemical and molecular features of two affected sisters in whom a nove...

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...

Introduction: It is thought that sex hormone binding protein (SHBG) is involved in glucose homeostasis in addition to regulate the levels of sex hormones. Clinical studies associate reduced SHBG concentrations with insulin resistance (IR).Objective: To evaluate the relationship of SHBG with IR and hyperandrogenism markers in a group of adolescents affected with polycystic ovarian syndrome (PCOS), and how weight could affect these markers.<p class="ab...

Background: Polycystic ovary morphology (PCOM) in USG should not be identified with polycystic ovary syndrome (PCOS) and it is not a criterion for diagnosis of this syndrome in adolescents.Objective and hypotheses: Assessment of the usability of 3D ultrasonography in diagnostics of androgen excess disorders.Method: 40 girls aged 14–18 with hyperandrogenism were subjected to endocrinological examinations and transrectal USG of ...

Background: The optimal timing and appropriate first-line investigations for delayed menarche in an otherwise well teenager with fully developed secondary sexual characteristics is debatable.Case presentation: A 15 year-old female presented with parental concerns of cliteromegaly. Facial acne and primary amenorrhoea were also noted. Pubic hair development started at age 10 years and breast development age 12 years. Family history revealed delayed menarch...

Background: As a curative therapy, haematopoietic stem cells transplantation (HSCT) has been also used for patients with non-neoplastic diseases such as aplastic anemia, primary immunodeficiency, and some congenital metabolic diseases. For these diseases, the intensity of the conditioning has been reduced comparing to that of malignancy diseases. Therefore, late effects of HSCT for non-neoplastic diseases has been expected to be milder than that for neoplastic diseases, howeve...
