Botulism is neuromuscular paralysis secondary to a neurotoxin secreted from Clostridium Botulinum bacteria. It is a rare syndrome as a result of food poisoning with the spore-forming clostridium bacteria. The ingested food is contaminated with the pre-secreted botulinum toxin. Infant botulism occurs with the ingestion of the clostridial spores that later germinate and colonize the intestine and...

Botulinum neurotoxin (BoNT), the most toxic substance known to mankind, is the first example of the fully active molten globule state. To understand its folding mechanism, we performed urea denaturation experiments and theoretical modeling using BoNT serotype A (BoNT/A). We found that the extent of BoNT/A denaturation from the native state (N) shows a nonmonotonic dependence on urea concentrati...

This paper describes our experience in the management of the pharyngocutaneous post-laryngectomy fistula with Botulinum neurotoxin-A injections into both parotid glands. It includes the rationale of the treatment, the physiological and pharmacological basis for this clinical application, the injection technique and the good results achieved. Our findings suggest that Botulinum neurotoxin offers...

Human exposure to botulinum toxin typically occurs in two settings: 1) as an etiologic agent in the disease botulism and 2) as a therapeutic agent for the treatment of dystonia. Epidemiologic studies on botulism suggest that the human nervous system is susceptible to five toxin serotypes (A, B, E, F and G) and resistant to two (C and D). In the past, these epidemiologic findings have been used ...

BACKGROUND Since the first comprehensive description of the physiologic effects of botulism toxicity in the 1820s, specific formulations of botulinum neurotoxin type A (BoNT-A) have been developed. Now, a new botulinum neurotoxin type A formulation (BoNTA-ABO; Dysport [abobotulinumtoxinA]; Medicis Aesthetics, Scottsdale, AZ) has been made available in the United States and these same physiologi...
