Fertility Preservation in Experimental Models in DSD

Rod Mitchell

The impact of DSD on future fertility is dependent on several factors. The key determinant of fertility potential is the status of gonadal development and function, and whether the individual has ovarian tissue with viable oocytes, or testicular tissue capable of producing functional sperm. Fertility risk will be primarily determined by the underlying diagnosis, modified by several additional factors. Whilst fertility preservation options are well established for many patient ...

Fertility preservation in children with cancer

Mitchell Rod

Fertility is dependent on the normal development of germ cells, which is controlled by hormones and paracrine factors produced by the somatic cells within the gonads. However, exposure to cancer treatment during childhood can cause damage to the gonads leading to infertility in adulthood [1]. This presentation will explore how various cancer treatments affect gonadal function based on clinical evidence in patients [2], experimental models involving animals and studies utilisin...

Disruption of Testicular Development and Function

Mitchell Rod

Male reproductive disorders are common and there is evidence for increasing incidence over recent decades. These disorders may present at birth (hypospadias and cryptorchidism) or in adulthood (infertility, testicular cancer) and can arise as a result of underlying genetic abnormalities or following environmental (e.g. phthalates) and pharmaceutical (e.g. analgesics, chemotherapy) exposures that impact fetal, neonatal of prepubertal testicular development. Understanding the re...

Is testosterone supplementation required after induction of puberty in Duchenne muscular dystrophy? A follow-up study

Wood Claire , Mitchell Rod , Guglieri Michela , Straub Volker , Cheetham Tim

Introduction: Pharmacological doses of glucocorticoids (GC) reduce inflammation and preserve muscle function in boys with Duchenne muscular dystrophy (DMD) but cause almost universal pubertal delay. Long term consequences of GC on androgen status in young men who have received testosterone for pubertal induction remain unknown.Objective: To determine the longer-term outcome after a 2-year pubertal induction regimen using...

Mitchell-Riley Syndrome, A Report of Novel Mutation in a Palestinian Family Resulting in Neonatal Diabetes

Abu-Libdeh Abdulsalam , Abu-libdeh Bassam

Introduction: Mitchell Riley syndrome is a rare autosomal disorder, characterized by severe neonatal diabetes associated with hypoplastic or annular pancreas, duodenal or jejunal atresia, intestinal malrotation, gallbladder hypoplasia or agenesis, and cholestatic disease, less common features were reported such as severe neonatal anemia, hemochromatosis and biliary atresia.Mitchell-Riley syndrome is caused by a mutation in regulatory fac...

Clinical Management of the Mitchell-Riley Syndrome Due to RFX6 Gene Mutations: Aggressive Support Results in Improved Outcome

Poidvin Amelie , Chandra Vikash , Fauret-Amsellem Anne-Laure , Cave Helene , Beltrand Jacques , Tubiana-Rufi Nadia , Carel Jean-Claude , Polak Michel , Scharfmann Raphael

Background: Homozygous mutations in the transcription factor RFX6 are the cause of the Mitchell-Riley syndrome associating neonatal diabetes, pancreatic hypoplasia, gallbladder agenesis, duodenal atresia, and severe chronic diarrhea. Nine cases have been reported so far and the condition has a poor prognosis with five of nine patients died before the age of 6 months.Objective and hypotheses: To report on the clinical management and outcome of tw...

Effects of Exposure to the Endocrine disruptor di(n-butyl) Phthalate on Testicular Dysgenesis Fetal Germ Cell Development in the Rat and in Human Fetal Testis

Mitchell Rod , van den Driesche Sander , Hrabalkova Lenka , Anderson Richard , McKinnell Chris , MacPherson Sheila , Calarrao Ana , Sharpe Richard

Background: Phthalate exposure results in endocrine disruption by inhibiting steroidogenesis, inducing focal dysgenesis and disrupting germ cell development in the rat fetal testis. Whilst phthalate exposure does not reduce testosterone production by the human fetal testis, its effects on germ cells and induction of dysgenetic areas in the developing human testis are less well described.Objective and Hypotheses: To determine the effects of phthalate expo...

SDgeneMatch, A New Tool to Aid the Identification of the Genetic Causes of DSD

De Ridder Jeroen , Bashamboo Anu , Baere Elfride De , Krone Nils , Mitchell Rod , Meyts Ewa Rajpert-De , Tobias Ed , Looijenga Leendert , Achermann John , Werner Ralf , Ahmed Faisal , Hiort Olaf , Greenfiled Andy , McElreavey Ken

Currently, the majority of patients with DSD do not have a molecular diagnosis. Although high throughput sequencing is having an impact on the clinical diagnosis of DSD the accurate interpretation genomic datasets of the identification of new gene mutations causing DSD is challenging. This is due to emerging evidence that DSD may be caused by mutations in many different genes and the prevalence of mutations in a single gene may be very low. As larger number of DSD patients are...

Background: Recurrence of craniopharyngiomas influences mortality. Apart from the extent of surgical resection, few clinical parameters have been consistently shown to be associated with recurrence. Radical resection is difficult due to infiltration of surrounding tissue and unacceptable morbidity. Predictors of recurrence are therefore needed.Aim: To establish a multinational cohort of patients with craniopharyngioma an...

British Society for Paediatric Endocrinology and Diabetes Peer Review of Specialised Paediatric Endocrinology Services in the UK - Evaluation of the Outcomes

Schulga Joihn , Mitchell Heather , Musson Pauline , Shaw Nick , Patel Leena

Introduction: The BSPED Peer review programme was initiated in 2011 to provide a regular cycle of independent impartial professional assessment, against quality standards for Specialised Paediatric Endocrine Services (SPES) in the UK.1 We present here an evaluation of the outcomes from the first review cycle completed in 2017.Methods: We examined pre-review self-assessments (4–6 weeks before a site visit by the Peer Review team) and post-...
