[Electronistagmographic characteristics of vestibular function and eyelids dystonia in patients with facial dyskinesias].

Electronistagmography has been performed in a vestibular function study of patients with facial dyskinesias - blepharospasm and facial hemispasm - before and after treatment with botulotoxin type A (dysport). A comparison groups included patients with myasthenia, functional dyskinesias, Greffe myodystrophy and healthy people. The method was applied for hyperkinesis objectification in patients with facial dyskinesias with the high amount of muscles artifacts caused by involuntary contractions of eye orbicular muscle.

[Efficacy and side-effects of the botulinum toxin A treatment in patients with focal dystonia].

An aim of the study was to determine side-effects of disport, the botulinum toxin A (BTA), in the treatment of patients with spasmodic torticollis (ST) and blepharospasm (BS). More than 800 injections of BTA to patients with ST and 110 - to patients with BS have been performed for 6-years period. Side-effects are specified as follows: 1) autonomic reactions observed in women with increased anxiety and signs of autonomic dysfunction (47,5%) patients with ST), with most marked symptoms in the first injection and their further decreasing; 2) local side-effects related with errors in dose adjustment, injection technique (37,3% patients with ST and 59,5% patients with BS); 3) the smallest group of side-effects not related to the doctor's experience and adequate psychological preparation of the patient for manipulation (myasthenia-myopathia syndrome after the BTA therapy).
