Background: Hematopoietic stem cell transplantation (HSCT) recipients are at risk of endocrine complications as a result of chemotherapy and radiation therapy. Development of diabetes mellitus (DM) after HSCT is less frequently reported compared with other complications.Objective and hypotheses: We investigated clinical features of newly diagnosed DM after HSCT for treatment of childhood leukemia.Method: Between April 1999 and Marc...

Introduction: There are few longitudinal male cohort studies with serial assessments of growth and puberty.Objective: To describe the design and implementation of a longitudinal cohort study of Russian boys evaluated annually for growth, development and puberty.Design/methods: We assembled a multi-disciplinary team of U.S. and Russian researchers to design and conduct a longitudinal boys’ cohort study in Chapaevsk, Russia with...

Background: DMRT transcription factors are highly conserved regulators of metazoan sexual development. The role of DMRT1 in human primary sex-determination is unclear. Chromosome 9p deletions that remove one copy of DMRT1 are associated with 46,XY feminization and gonadal dysgenesis. While they suggest that DMRT1 is haploinsufficient for testicular development, these deletions usually remove other genes, including DMRT2 and DMRT3. Also, most 9p deletions cause incomplete gonad...

Background: Due to the rarity of Paediatric Cushing’s disease (CD) there is limited data on the long-term consequences of treatment.Objective and hypotheses: We assessed recurrence, anterior pituitary function and psychiatric disorders in a group of paediatric CD patients treated in a single centre.Method: Retrospective review of 20 patients with CD, mean age 11.75 years (5.74–17.8), managed in our centre between 1986 and...

Background: Cushing’s syndrome (CS) in children remains a challenge to diagnose and exclude. Published diagnostic guidelines for CS are heavily based upon adult data. The use of 24-h urinary free cortisol (UFC) measurements in the diagnosis of adult CS may have limited use. There is little data on the utility of 24-h UFC in children.Objective and hypotheses: We hypothesised that 24-h UFC is a robust and reliable screening test in children. The study...

Background: A subset of central obese but normal weight individuals has been identified, who harbor potentially increased risks for development of MS despite a normal BMI.Objective and hypotheses: We try to evaluate metabolic syndrome (MS) components of normal weight central obese adolescents in Korea stratified by waist-to-height ratio (WHR).Method: This is a cross-sectional study. Data were obtained from the Korean National Healt...

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: In adolescents, as much as 51% of peak bone mass is accumulating and reaching 40% of bone mineral density (BMD) of adults. There are inconsistent reports on the associations between birth weight (BW) and bone mineral contents (BMC) in adolescents.Objective and hypotheses: We try to investigate the association between BW and BMC in adolescents.Method: Dual-energy x-ray aborptiometry assessment (DXA) of 10–18 adolesc...

Background: We are not aware of other longitudinal cohort studies of boys with annual assessments of pubertal development and long term follow-up to adulthood to evaluate semen quality.Objective: To describe semen quality and investigate its predictors in a longitudinal cohort study of Russian boys followed from prepuberty until adulthood.Design and methods: From 2003 to 2005, 516 prepubertal 8–9-year-old boys were enrolled (8...

Background: We are not aware of other longitudinal cohort studies of boys with prepubertal assessment of exposure to endocrine-disrupting chemicals (EDCs) and annual long term follow-up of growth and puberty to evaluate semen quality.Objective: To describe semen quality and explore associations of prepubertal serum concentrations of organochlorine compounds and pubertal measures with semen parameters in an ongoing longitudinal cohort study of Russian boy...
