ABSTRACT
We report the results of botulinum toxin type A (Dysport, Porton Products, UK) treatment over 5 years in 107 patients with blepharospasm, Meige's syndrome, oromandibular dystonia, hemifacial spasm, cervical dystonia, and writer's cramp. Electromyography was used to localize dystonic muscles and guide Dysport injections in Meige's syndrome, oromandibular dystonia, cervical dystonia, and writer's cramp. All but 2 Meige's syndrome and 2 writer's cramp patients responded to treatment. Improvement was dramatic in blepharospasm (79%) and hemifacial spasm (90%); pronounced in cervical dystonia (74%); and moderate in Meige's syndrome (53%), oromandibular dystonia (57%), and writer's cramp (34%). Although Dysport doses were 50-75% lower than usually reported, response and improvement rates as well as relapse intervals were similar to those of others. To treat cervical dystonia relapses, only 50% of the initial dose was required for continued optimal relief of symptoms. Low-dose Dysport was associated with a very low incidence of dysphagia in cervical dystonia.

After two seizures, a 13 year-old boy experienced headache, fatigue and loss of appetite over a period of 3 weeks. There was a bilateral papilledema with normal visual acuity. CT and MRI disclosed two ischemic foci, that were interpreted as evidence of vasculitis. High serum levels of IgG and IgM antibodies specific to Borrelia burgdorferi, were present. The patient had attended an outdoor scout camp in a area, in south-east Belgium, known to be endemic for tick-born borreliosis. The clinical symptoms, the levels of the specific antibodies and the radiologic abnormalities responded dramatically to treatment. We believe that seizures in this case were related to cerebral vasculitis. This case confirms the extreme diversity of the neurological manifestations of Borreliosis.
