Research Expertise


General Paediatrics is an acute specialty caring for the undifferentiated child. It is an emerging academic specialty with a focus on clinical research and quality improvement. Since my time as a fellow at RCH Melbourne I concentrated on early child development and how clinicians and parents must collaborate to define a child's abilities in the home, school and play settings. This work included those with developmental delay and those with more severe disabilities such as cerebral palsy. More recent work has focused on interventions including Vitamin D supplementation to improve symptoms in children with Autism and Asthma. While adequate nutrition is essential many child still require daily medication and my work has also looked at improving methods of medication administration in those with acute infection, allergy and complex needs. A novel method of delivering anti-epileptic method through a feeding tube was described with great benefits for children with complex needs. Randomised Controlled trials: 1. RCT of Vitamin D supplementation in autism spectrum disorder. Randomised 42 children to receive 2000 IU Vitamin D3 daily or placebo over 20 weeks. Vitamin D had no effect on primary outcome of reducing stereotypic autistic behaviours. Trend towards reduced inappropriate speech in the Vitamin D3 treatment group. 2. RCT of Vitamin D supplementation in uncontrolled asthma. Randomised 44 children with uncontrolled asthma to receive 2000 IU Vitamin D3 or placebo over 15 weeks. Vitamin D had no effect on primary outcome of improved subjective asthma control or Fev1 on spirometry. There was a non significant improvement in Fev1 within the placebo group. 3. EVITA Trial (NIHR UK) 2024. A 3 way trial exploring equipoise between intravenous magnesium sulphate, salbutamol, and aminophyllin in children with severe acute asthma. Awaits funding Finally we've explored variation in medication response by examining genetic variants in asthma. An association was found between Taql (exon 9) and Apal (intron 8) polymorphisms and asthma risk. IL10 levels were lower in asthmatic children with Taql polymorphisms. I've also developed national guidelines published as the WIGUAM Study (Working to Implement National Guidelines for Urine Tract Infection Assessment and Management ).

  • Title
    • An RCT of Vitamin D3 in Uncontrolled Asthma
  • Summary
    • A double-blind, randomized, PL-controlled trial of vitamin D supplementation (2000 IU/day) in 44 urban, caucasian children at high latitude. Conclusion: Vitamin D3 supplementation led to a significant increase in serum 25(OH)D and decreased school days missed (p = 0.04), but no other advantageous changes in asthma parameters compared with PL.The potential negative effect of high serum 25(OH)D on pulmonary function warrant further investigation.

    • An RCT of Vitamin D3 in Paediatric Autism
  • Summary
    • A double-blind, randomised, placebo-controlled trial set in a paediatric outpatient centre at high latitude over the winter season in Dublin, Ireland (53°N). Conclusion: Vitamin D supplementation had no effect on the primary outcome with limited and inconsistent effects in children with ASD. Considering the other promising data as well as the relative safety and cheapness of vitamin D supplementation, further trials are warranted.

  • Title
    • PROSPER: PaediatRic Outcomes and Serum biomarker Panel in acutE traumatic bRain injury /concussion to severe traumatic 2015-9.
  • Summary
    • To describe the demographics and aetiology of traumatic brain injury presenting to Irish Paediatric Emergency Departments. Concussion and mild traumatic brain injury (mTBI) are interchangeable terms.Post-concussion syndrome (PCS) occurs in 1/7 children sustaining a mTBI.Secondly to describe physician competence in this condition and to develop a best practice guideline. To elucidate biomarkers from the innate immune system that are activated in acute brain injury. Findings include preschool children have the highest incidence of head injury, mostly following a fall. There was a paucity of knowledge among all grades of medical professionals in how to manage these children. Many patients had a raised white cell count with neutrophilia. Surprisingly CD 11b neutrophil expression was not raised in mTBI on flow cytometry, but was markedly raised in the 4 most severe TBI patients.

  • Title
    • FIG Study
  • Summary
    • Faltering growth In General paediatrics Clinic (FIG) was a 1 year study exploring the determinants of poor growth in toddlers. The effect of maternal and social factors on faltering growth (FG) are unclear from published research. A control comparison of 24 children recruited through clinics in AMNCH was undertaken (12 FG, 12 controls). Participating parents completed a health, social,and demographic questionnaire and a 7 day food diary was completed using household measures. Diaries were analysed using NETWISP for protein , fat, carbohydrate, and vitamin content. All data were entered in SPSS. There were no significant difference between FG and control groups in maternal health or social factors. There were no differences in the feeding histories between the two groups. However the mean intake of all nutrients except protein, monounsaturated fat, starch, sodium and B12 were all higher in the control group. These findings support hypothesis that poor nutritional intake is main cause of faltering growth in this group. There was a trend towards lower breast feeding rates in the FG group.
