Botulinum toxin type A versus botulinum toxin type B for cervical dystonia

Botulinum toxin type B for cervical dystonia.

BACKGROUND Cervical dystonia is the most common form of focal dystonia. It is characterized by involuntary posturing of the head and frequently is associated with neck pain. Disability and social withdrawal are common. Most cases of cervical dystonia are idiopathic and generally it is a life-long disorder. In recent years, Botulinum toxin type A (BtA) has become the first line therapy. However,...

Botulinum toxin type B micromechanosensor.

Botulinum neurotoxin (BoNT) types A, B, E, and F are toxic to humans; early and rapid detection is essential for adequate medical treatment. Presently available tests for detection of BoNTs, although sensitive, require hours to days. We report a BoNT-B sensor whose properties allow detection of BoNT-B within minutes. The technique relies on the detection of an agarose bead detachment from the t...

Botulinum toxin therapy for cervical dystonia

Cervical dystonia, or torticollis, is perhaps the most common form of focal dystonia. The discovery that botulinum toxin was beneficial in the treatment of this disorder had a twofold impact. First, it silenced a small minority of physicians who believed that this disorder had a psychogenic basis despite convincing evidence to the contrary. Second, it alerted physicians to the broad potential o...

Botulinum toxin type B for dynamic glabellar rhytides refractory to botulinum toxin type A.

BACKGROUND Botulinum toxin type B (BTX-B; Myobloc) has recently been introduced for the treatment of dynamic rhytides. This serotype is structurally similar to botulinum toxin type A (BTX-A; Botox) and appears to produce equivalent muscular paralysis. Because of the fact that some patients may become resistant to the effects of BTX-A with its continued use or may require large doses of type A t...
