A dual centre evaluation of discontinuation of testosterone therapy in boys with Duchenne Muscular Dystrophy

Choong Wong Sze , Loughnan Myles , Zacharin Margaret

Background: The 2018 international standards of care for DMD recommend initiating testosterone for management of delayed puberty commencing at a low dose, gradually increasing to adult replacement. No recommendations exist regarding longer term use of testosterone during transition and adulthood.Aim(s): To report long-term use of testosterone in DMD with outcomes of gonadal function and pubertal development in those who ...

A case series of multinodular goitres associated with tumour predisposition syndromes

Angley Eleanor , Farrell Stephen , Zacharin Margaret

Thyroid nodular disease, either multinodular goitre (MNG) or solitary nodule, carries a higher malignancy risk in paediatric patients compared to adults requiring closer monitoring and investigation. We present a case series of patients with multinodular goitre who were confirmed to have tumour predisposition syndromes. Eight patients (six female) with MNG were identified using electronic medical records, based on presence of MNG and/or previous genetic testing confirming eith...

Evaluation of Endocrine Late Effects in Survivors of Childhood Allogeneic Hematopoietic Stem Cell Transplantation in Australia – Database from 1985 to 2011

Lai-Ka Lee Samantha , Tiedemann Karin , Zacharin Margaret

Background: With improved survival of childhood allogeneic hematopoietic stem cell transplant (HSCT), there is increasing need for surveillance, including assessment of endocrine late effects in this cohort1,2.Aim: To evaluate endocrine late effects after chemotherapy and radiation in survivors of childhood allogeneic HSCT.Methods: Multi-site evaluation via medical recor...

YAP1-HIPPO Pathway as a Novel Prognostic Marker and Therapeutic Target for Pediatric Patients with Adrenocortical Tumors (ACT)

More Candy Bellido , Bueno Ana Carolina , Castro Margaret , Antonini Sonir

Background: There is no effective adjuvant therapy for patients with advanced ACT. YAP1, a HIPPO pathway effector, interacts with Wtn\beta-catenin pathway and plays a crucial role in the maintenance of postnatal adrenal cortex and regulates cell proliferation and apoptosis in several tissues. We recently showed that overexpression of YAP1 associates with worse prognosis in our cohort of pediatric ACT (pACT).Aim: To analy...

Long-term Outcomes of Osteogenesis Imperfecta in the Bisphosphonate Era

Feehan Andrew , Zacharin Margaret , Lim Angelina , Simm Peter

Background: Bisphosphonates have been used for treatment of bone fragility disorders for over 25 years to increase bone mineral density (BMD). Anecdotally, bisphosphonate-treated Osteogenesis Imperfecta (OI) has a different trajectory to the natural history of untreated OI, with minimal published evidence to support this clinical observation.Aims: To describe functional outcomes of a cohort of adults with OI, stratified according to severity and treated ...

Spontaneous Pregnancies in Female Survivors of Childhood Hematological Malignancies Post Allogeneic Haemopoietic Stem Cell Transplantation

Lai-Ka Lee Samantha , Zacharin Margaret , Tiedemann Karin

Background: With improved treatment and survival of childhood hematological malignancies, the issue of fertility in survivors has become an important domain of holistic care. Haemopoietic stem cell transplant (HSCT) survivors were reported to have reduced fertility as compared to siblings, with 4/170 adult female allogeneic HSCT survivors achieving successful pregnancy.1 Of 532 female survivors, median age of 17.8 years at HSCT, who had TBI conditioning, 13 pregnanc...

Zoledronic Acid for Management of Osteopenia of Prematurity and Associated Ventilator Dependency

White Mary , Pellicano Anastasia , Zacharin Margaret , Simm Peter

Background: The effect of bisphosphonates in patients with severe osteopenia of prematurity is unknown in terms of either fracture prevention or long-term safety. A 6-month-old male infant born at 24+2 weeks gestation was referred for consideration of bisphosphonate therapy in the management of severe osteopenia of prematurity. The neonatal course included chronic lung disease requiring four courses of corticosteroids. Despite optimal calcium, phosphate and vitamin D supplemen...

Evaluation of a Novel Tool to Adjust Insulin Boluses Based on Continuous Glucose Monitoring Trend Arrows and Insulin Sensitivity (Trend Arrow Adjustment Tool©) in Children and Youth with Type 1 Diabetes Using Insulin Pump Therapy

Heffernan Emmeline , Lawson Margaret , Bradley Brenda , Courtney Jennilea , Richardson Christine

Background: Continuous glucose monitoring (CGM) measures interstitial glucose and displays trend arrows, showing the direction and rate of change in glucose. Trend arrows allow the child/youth to take action to prevent hyper- and hypoglycaemia. Effective strategies for adjusting insulin for trend arrows are lacking. The JDRF CGM Study Group recommended a 10–20% increase/decrease in the insulin dose. However, the bolus dose is dependent on amount of food to be consumed and...

Phaeochromocytoma in Placental Mesenchymal Dysplasia: Who Should We Screen and for How Long?

White Mary , McGillivray George , White Sue , Zacharin Margaret

Background: Beckwith-Wiedemann syndrome (BWS) characterised by a group of clinical abnormalities (macrosomia, macroglossia, neonatal hypoglycaemia, omphalocoele and umbilical hernia) results from dysregulation of imprinted genes due to mosaic paternal uniparental isodisomy (patUPD) of 11p15.5. Its association with tumours of embryonic origin is well documented and screening guidelines largely aim to detect hepatoblastoma and Wilm’s tumours during the first decade of life....

Background: The COVID-19 pandemic continues to impact healthcare overall particularly in relation to diabetes. Initial studies showed delays in emergent healthcare utilization, decreased preventative care visits, and more severe presentations of new onset diabetes. However, the pathophysiologic relationship between COVID-19 and type 1 diabetes is not yet well understood.Objectives: Our primary objective was to compare th...
