Botulinum toxin treatment in neurological practice: how much does it really cost? A prospective cost-effectiveness study.

Botulinum toxin (BTA) is a safe and effective therapeutic tool for many neurological conditions but few studies have investigated its real cost in neurological practice. We evaluated the daily cost of botulinum toxin type A (BTA) treatment through a cost effectiveness analysis alongside a prospective study of BTA injections at a French University Hospital over a 2-year follow-up period. The data of 3,108 BTA injections performed in 870 adult patients presenting with dystonia, facial hemispasm, or spasticity were entered in the database.

Freezing of shoulder flexion impeding boule throwing: a form of task-specific focal dystonia in petanque players.

During a period of intensive practice, 2 petanque players developed freezing of shoulder flexion impeding boule throwing. This movement disorder was consistent with the diagnosis of task-specific focal dystonia. Polymyography showed that freezing was associated with bursts of low amplitude.
