It is acknowledged that children should collaborate in research about their health conditions, and DSD research has been criticised for promoting views of parents and health professionals. However parents are concerned about professionals talking to children about sensitive subjects including fertility and sexual activity. Children may have little experience of talking about their sex development. This makes direct research involving children with DSD particularly challenging....

We report mosaic triploidy 69XXY/46XX in ovotesticular DSD which poses significant diagnostic and management questions.Case: A baby born to non-consanguineous parents after a normal pregnancy, presented with atypical genitalia including significant clitoromegaly, a urethral opening in the anterior perineum and a normal vaginal opening. Bilateral masses were noted in the labio-scrotal folds. Pelvic ultrasound identified a normal uterus however the gonads ...

Background: Attention-deficit/hyperactivity disorder (ADHD) is the most prevalent neurodevelopmental disorder worldwide. Evidence suggests dysfunction of the fronto-subcortical pathways and the dopaminergic and noradrenergic systems, as well as dysregulation of the stress system, i.e., the hypothalamic–pituitary–adrenal (HPA) axis and the sympathetic nervous system (SNS).Objective and hypotheses: The aim of the study was to examine i) the diurn...

Background: Paediatric Osteoporosis can be a devastating complication of Duchenne muscular dystrophy (DMD). Treatment with intravenous bisphosphonates such as pamidronate is currently the first treatment choice for paediatric osteoporosis of different etiologies.Objective and hypotheses: The aims of our study were i) to identify the proportion of boys with DMD with osteoporosis in our service and ii) to evaluate the side-effect profile of those treated w...

Background: Diabetes is a recognised long term sequelae in childhood cancer survivors following bone marrow transplantation and total body irradiation (BMT/TBI), due to a combination of insulin deficiency and resistance.Aim: To characterise presentation, treatment and clinical course of diabetes in childhood leukaemia survivors post BMT/TBI.Method: A single centre retrospective case note review of diabetes post BMT/TBI identified f...

Background: Adult survivors of childhood leukaemia treated Bone marrow transplantation with total body irradiation (BMT/TBI) have an increased risk of diabetes mellitus (DM) disproportionate to their level of adiposity or other recognised risk factors. Post prandial hyperglycaemia due to reduced β-cell reserve after irradiation will be missed by fasting glucose (FG) levels. However, the UK National Institute of Clinical Excellence (NICE) screening guidelines recommend the...

Background: The heterozygous mutation in the SRCAP gene (611421) on chromosome 16p11.2 causes a rare genetic disorder named Floating–Harbor syndrome (FHS). The clinical diagnosis of FHS is characterized by a triad of short stature with significantly delayed bone age; expressive language delay, usually in the presence of normal motor development; and a triangular face with prominent nose and deep-set eyes.Objective: To investigate the presence of SRC...

Background: Gonadotoxic cancer therapy may cause adult male infertility. We previously reported that, of 2/3rds of underage males agreeing to pre-treatment sperm cryopreservation before cancer treatment, 2/3rds succeeded.Objective and hypotheses: i) To evaluate how many patients banking sperm successfully (GP1) returned for post treatment re-evaluation compared with those who attempted but failed (GP2). ii) To compare intergroup survival and fertility ra...

Background: The Dutch HYPOthalamic and PITuitary gene (HYPOPIT) study investigates the genetic and non-genetic causes of isolated growth hormone deficiency (IGHD) and combined pituitary hormone deficiency (CPHD). Former projects within the HYPOPIT study showed that only a small minority of the Dutch IGHD and CPHD cases could be explained by mutations in GH1, GHRHR, HMGA2 and CDK6 in IGHD patients and PROP1, HESX1, POU1F1, LHX3</...

Background: Childhood haematopoietic stem cell transplantation and total body irradiation (HSCT/TBI) survivors have multiple risk factors for reduced bone mineral density (BMD) and poor growth. Reduced z-scores from dual energy x-Ray absorptiometry (DEXA) have been reported, but are unreliable in patients with short stature/abnormal body composition.Objective: To investigate the influence of HSCT/TBI on size-corrected BMD in childhood leukaemia ...
