BACKGROUND Data from previous studies suggest that botulinum toxin A has analgesic effects against peripheral neuropathic pain, but the quality of the evidence is low. We aimed to assess the safety and efficacy of repeated administrations of botulinum toxin A in patients with neuropathic pain. METHODS We did a randomised, double-blind, placebo-controlled trial at two outpatient clinics in Fra...

After Clostridium botulinum type G organisms and toxin were identified in necropsy specimens in cases of unexplained death in adults and infants (O. Sonnabend, W. Sonnabend, R. Heinzle, T. Sigrist, R Dirnhofer, and U. Krech, J. Infect. Dis. 143:22-27, 1981), extensive research to detect C. botulinum type G in soil samples from Switzerland was done. A total of 41 specimens from virgin soil and f...

Salivary duct injury can be idiopathic, iatrogenic, or post-trauma and may result in sialocele or fistula. Most injuries regress spontaneously and botulinum toxin A is one of several therapeutic possibilities. We report a case of iatrogenic injury to the parotid duct after Mohs' micographic surgery for a squamous cell carcinoma excision in the left jaw region, treated by injection of botulinum ...

The clinical eVects of botulinum toxin have been recognised since the end of the 19th century. It is the most potent neurotoxin known and it is produced by the gram negative anaerobic bacterium Clostridium botulinum. The paralytic eVect of the toxin is due to blockade of neuromuscular transmission. Injection into a muscle causes chemodenervation and local paralysis and this eVect has led to the...

The effectiveness of botulinum toxin injections for the management of Frey's syndrome was studied. Botulinum toxin A (approximately 0.5 Units/cm2) was injected intracutaneously into the affected skin area as determined by Minor's starch iodine test. Gustatory sweating in the treated skin area ceased completely within 1 week and has not reappeared (12 months follow up until now in the first trea...

This article is structured around a literature review that was carried out using Ovid and Medline with the key words "botulinum," "toxin," and "ENT." Botulinum toxin has been used safely in humans for more than 20 years. The effects are transient, such that treatments are required to be repeated at intervals. Its application to ENT provides a useful tool to treat dystonia, autonomic dysfunction...

Persistent genital arousal disorder is described in a spontaneous, persistent, and uncontrollable genital arousal in women, with or without orgasm or genital engorgement, unrelated to any feelings of sexual desire. This study aimed to argue that application of Botulinum toxin in the periclitoral region in order to block the dorsal nerve of the clitoris might decrease symptoms of persistent geni...

BACKGROUND A 41-year-old male patient developed a sialocele after partial parotidectomy for a parotid pleomorphic adenoma. The sialocele was effectively treated by a single injection with botulinum toxin type B combined with multiple needle aspirations. METHODS Ultrasound-guided infiltration of 2500 mouse-units of botulinum toxin type B in the residual parotid gland tissue under local anesthe...

The safety and efficacy of botulinum toxin for the treatment of focal hand and cranial dystonias are well-established. Studies of these adult-onset focal dystonias reveal both shared features, such as the dystonic phenotype of muscle hyperactivity and overflow muscle contraction and divergent features, such as task specificity in focal hand dystonia which is not a common feature of cranial dyst...
