The 3rd British Neurotoxin Network annual meeting was hold in Oxford last week; 74 Botulinum toxin injectors gathered for all over UK in the superb location of Keble college. The program covered both practical and scientific aspects of botulinum toxin and dystonia.
I gave a pre dinner talk on facial expression of emotions, looking on how the concepts have evolved from the 19th century with Charles Bells ‘s anatomical dissection of the facial muscles, to the 21st century with the influence of facial Botox injections on our expression of emotions.The collaboration of Duchenne de Boulogne with his neurophysiology study and Charles Darwin on expression of emotions in man and animals contributes to the present understanding of the universality of expressions and the recognition of basic emotions on a face, which was confirmed by Paul Ekman, an American psychologist.The Botox has been used as a research tool in the 21-st century to understand the relation between emotion and facial expression. Repressing the expression of emotions by too much cosmetic Botox or by neurological conditions such as facial palsy could disturb in return our ability to perceive emotions.

The following morning was dedicated on reviewing the techniques and indications of the treatment of drooling by Ms Helen Witherow, maxillo-facial surgeon in London, the treatment of jaw dystonia by myself and the comparison of 2 techniques of injection: either electromyographic guided or ultra sound guided injection by Dr Sabine Klepsch , neurophysiologist in Bristol. Ms Catharina Pearce, medical student from Cardiff presented the results of a national survey on the use of Botulinum toxin in pregnant women.
In the afternoon the lectures were focusing on new concepts in dystonia and in particular the attempt of defining a new endophenotype (heritable clinical markers) for adult onset focal dystonia by Dr Sean O’riordan from Dublin and Dr Richard Grunewald from Sheffield.
Outside the Botulinum toxin treatment, Mr Alex Green, neurosurgeon in Oxford, explored the effect of Deep Brain Surgery on dystonia and Mr Richmond Stace physiotherapist in London, the basis for retraining of cervical dystonia.
A video session, where colleagues were presenting video of dystonic patients with unexpected outcome, was animated and the opportunity again to share our individual approach to treatment.
The meeting was also a great opportunity for the secretary Mr Bells to update the UK maps of the service using botulinum toxin for treating neurological conditions. it’s accessible to anybody who is looking for a specialist centre to be treated for dystonia in particular.
