  • OBJECTIVE: As a newly established tuberous sclerosis clinic (TSC) clinic at The Hospital for Sick Children, we reviewed our referrals to determine if children with TSC received appropriate surveillance as advised by the 2012 International Tuberous Sclerosis Complex Consensus Recommendations. METHODS: We completed a retrospective review of all patients seen in the TSC clinic from January 2016 to December 2017 to determine if children referred to the clinic had appropriate surveillance as suggested by the Tuberous Sclerosis Complex Consensus Recommendations. RESULTS: Ninety patients were seen in the TSC clinic. The median age at first visit was 9.9 years, and 47 were males. Seventy-six percent had undergone genetic testing before the initial clinic visit; however, genetic counseling was completed in only 66%. Brain magnetic resonance imaging was completed in 94%, abdominal imaging was completed in 91%, and an echocardiography and electrocardiography in 88% and 83%, respectively. In addition, dermatology and ophthalmology evaluations were completed in 78% and 91%, respectively. Assessment of TSC-associated neuropsychiatric disorders (TAND) was only completed in 4% of the patients. CONCLUSIONS: Systems surveillance was completed in the majority before the first TSC clinic visit. However, TSC-associated neuropsychiatric disorder screening was completed in few cases. This suggests that referring physicians may not be familiar with the neuropsychiatric manifestations of TSC and that there may be underdiagnosed or undertreated illness. Future emphasis should be placed on educating all practitioners to assess and treat tuberous sclerosis complex-associated neuropsychiatric disorder in tuberous sclerosis complex.
