Background: Girls with Turner Syndrome (TS) are at increased risk of primary ovarian failure. Previous studies have demonstrated that urinary gonadotrophins (UG) can be used as a non- invasive biochemical marker of pubertal status but their value in monitoring and managing girls with primary ovarian failure is unclear.Aims: To determine the range of UG in girls with Turner Syndrome (TS) and its correlation to serum LH and FSH.Patie...

Introduction: Bisphosphonate therapy (BPT) reduces osteoclast activity and may be associated with adynamic bone turnover. The extent of suppression of bone turnover and its determinants are unclear.Methods: Markers of bone metabolism were evaluated in 15 children (9M/6F) receiving cyclical BPT intravenously for osteoporosis. The median age at first biochemical assessment was 10.8 years (0.16, 16.3). Serum type I collagen cross-linked C-telopeptide (CTX),...

Introduction: In children undergoing investigation of testicular function the relationship between serum anti-Müllerian hormone (AMH) and the testosterone response to hCG stimulation test (HST) is unclear.Methods: 71 children (three females and 68 males) with a median age of 1.08 years (range: 0.003, 14.3) were investigated for suspected DSD by AMH on D1 and testosterone on D1 and D4, before and after 3-day HST. Of these children, 27 had an addition...

Introduction: Transcriptome analysis of peripheral blood mononuclear cells (PBMC) RNA has identified a set of androgen-responsive non-coding RNAs.Aim: To quantify the androgen-responsive gene expression and investigate its relationship to the testosterone (T) rise following hCG stimulation in boys with no genetic evidence of androgen insensitivity.Methods: Boys with suspected DSD who were evaluated at the Royal Hospital for Childre...

Introduction: With improvements in assays and the increasing need for non-invasive, out-patient based investigations, there is a renewed interest in the use of urinary gonadotrophins (UG) for assessing pubertal progress. This study aims to establish the correlation between serum and urinary LH and FSH in patients undergoing investigation or management of pubertal disorders.Methods/design: Retrospective evaluation of eight patients undergoing investigatio...
