IDA alone is one of the main indications (27%) for referral to SBCE; the majority of patients are >40 years. In our cohort, the DY of SBCE for IDA was 30.7% and the commonest finding was angioectasias. The detection rate of sinister small-bowel pathology for those >40 years is low decreasing to zero in the >80 age group. In contrast, 25% of those ≤40 years had a sinister diagnosis.

IntroductionVarious presentations of essential palatal myoclonus, a condition characterized by clicking noises and palatal muscle spasm, have been reported in the literature. We are reporting the first case of essential palatal myoclonus following dental treatment.Case presentationA 31-year-old Caucasian man presented to our Ear, Nose and Throat department complaining of objective clicking tinnitus occurring immediately after he had undergone root canal treatment on his right lower third molar 3 months ago. Magnetic resonance imaging of his head revealed no abnormalities in the cerebrum, cerebellum or brainstem making the diagnosis essential palatal myoclonus. He returned a week later, and 20 units of botulinum toxin A (Allergan) were injected into his left tensor veli palatine muscle. He reported an immediate improvement; however, symptoms recurred 6 months later.ConclusionsDental treatment can be a trigger of essential palatal myoclonus. Botulinum toxin injections are an effective treatment for short-term relief of symptoms.
