    • Metanalysis of cortical venous sinus thrombosis

    My main area of interest is neuromuscular disorders. I have a particular focus on Duchenne Muscular Dystrophy (DMD). Neuromuscular disorders involve many disciplines. A greater understanding of genetics is leading to greater knowledge and the potential for more definitive treatment for neuromuscular disorders in childhood.

    We are now developing a Canadian Registry of children with DMD and with congenital myotonic dystrophy, and are now involved with clinical trials of new potential treatments.

    In view of the fact that these children are now living into adulthood, we are also establishing a protocol for a natural history study of our affected young adults. We wish to ensure we can provide the most appropriate management.

    Current Projects

    PTC-DMD Study - A Phase 2b Efficacy and Safety Study of PTC124 in Subjects with Nonsense-Mutation-Mediated Duchenne and Becker Muscular Dystrophy
    The development of PTC124 offers a novel therapeutic approach to the treatment of genetic disorders: coupling the identification of patients with a specific type of genetic defect with a small-molecule therapy that has the potential to correct the phenotypic expression of that genetic defect. 

    We hypothesize that the mean change in 6MWD from Day 1 (Visit 3 – Baseline) to Week 48 (Visit 11 – End-of-Treatment) will be 30 meters longer in at least one of the PTC124 arms than in the placebo arm. The primary objective of this study is to evaluate the ability of PTC124 to improve ambulation as assessed by change in 6MWD.

    MIT Study – A Retrospective Review of the Diagnostic Outcome of Skeletal Muscle Biopsy for Suspected Mitochondrial Disease at BC Children's Hospital
    The study includes a 5 year retrospective chart review of the diagnostic outcome of pediatric patients who have undergone a skeletal biopsy for a suspected mitochondrial disease at BC Children's between January 1998 and June 2003.

    The objectives of the study include:

    • To evaluate the diagnostic outcome of patients who have undergone a skeletal biopsy for a suspected mitochondrial disease for quality assurance purposes
    • To determine the number of patients that received a diagnosis of mitochondrial disease using other diagnostic tests
    • To identify patients’ factors that predict a higher skeletal muscle biopsy yield
    • To establish detailed demographic and clinical patient database
