Together with colleagues from the Medical University of Vienna and the University of Vienna (Faculty of Chemistry), they studied tumors of the peripheral nervous system in children, namely neuroblastomas.

Streptococcus (GAS) exposure were unrelated to tic exacerbations in children with chronic tic disorders (CTD), including Tourette syndrome, a prospective cohort study found.

In 715 children with CTD who had mean age of 10.7 and who mostly (77%) were boys, researchers assessed tic, obsessive-compulsive symptoms, and attention deficit/hyperactivity disorder (ADHD) severity through weekly symptom diaries, regular clinic visits, and telephone calls over an average follow-up of 16 months. A clinical assessment visit was done when symptom worsening was reported.
