We have read the case report of Al-Ahmad and Al-Qudah1 regarding the use of botulinum toxin type A in the treatment of masseter hypertrophy, and we agree with the authors when they reported that botulinum toxin type A is an option for patients who declined surgical treatment. However, we would like to make some considerations concerning this type of treatment that can contribute to the authors’...

In this Practice article by Antony Smith and colleagues (BMJ 2013;347:f5170, doi:10.1136/bmj.f5170), the section on use of botulinum toxin A for treating overactive bladder wrongly stated that botulinum toxin type A did not have a UK marketing authorisation for this indication. It should have stated: “At the time of publication (September 2013), most botulinum toxin type A preparations did not ...

Botulinum neurotoxin (BoNT) is the most poisonous substances known and its eight toxin types (A to H) are distinguished by the inability of polyclonal antibodies that neutralize one toxin type to neutralize any of the other seven toxin types. Infant botulism, an intestinal toxemia orphan disease, is the most common form of human botulism in the United States. It results from swallowed spores of...

In this article, the evidence base for botulinum-A treatment acquired in recent years is outlined, and the practicalities involved in providing this service are described. Botulinum-A is relatively new, and possible improvements for the future are considered.

Botulinum neurotoxins (BoNTs) are some of the most poisonous natural toxins. Botulinum neurotoxins associate with neurotoxin-associated proteins (NAPs) forming large complexes that are protected from the harsh environment of the gastrointestinal tract. However, it is still unclear how BoNT complexes as large as 900 kDa traverse the epithelial barrier and what role NAPs play in toxin translocati...

Background: Use of botulinum toxin is becoming a popular way in treatment of some forms of strabismus.To evaluate the morphological changes in the orbital surface layer muscles of the rabbit eye following a single injection of botulinum toxin. Methods: 10 white Dutch rabbits weighing 2–3 kg received either 10 units (group 1; n=5) or 20 units (group 2; n=5) of botulinum toxin into the superior r...

OBJECTIVE Treatment strategies for post-stroke spasticity include oral anti-spastic drugs, surgery, physiotherapy and botulinum toxin type A injection. The objective of this study was to compare the cost-effectiveness and outcomes of oral therapy vs. botulinum toxin type A treatment strategies in patients with flexed wrist/clenched fist spasticity. METHODS Treatment outcome and resource use d...
