[The route of botulinum toxin from cause of food poisoning to medical remedy]. / Botuliinin tie ruokamyrkytyksen aiheuttajasta lääkkeeksi.

Botulinum toxins are amongst the most poisonous substances known in nature. The discovery and development of this toxin into a medical remedy is one of the most fascinating stories in the history of medicine. German physician Justinus Kerner founded the theory of treating hyperactive disorders with botulinum toxin and Alan Scott was the one to make this happen successfully. Nowadays the toxin is widely used in different indications, and the research is still going on for discovering novel tools for treating e.g. pain.

From poison to remedy: the chequered history of botulinum toxin.

Botulinum toxin poisoning has afflicted mankind through the mists of time. However, the first incident of food-borne botulism was documented as late as the 18th century, when the consumption of meat and blood sausages gave rise to many deaths throughout the kingdom of Württemberg in South Western Germany. The district medical officer Justinus Kerner (1786--1862), who was also a well-known German poet, published the first accurate and complete descriptions of the symptoms of food-borne botulism between 1817 and 1822 and attributed the intoxication to a biological poison. Kerner also postulated that the toxin might be used for treatment purposes. In 1895, an outbreak of botulism in the small Belgian village of Ellezelles led to the discovery of the pathogen "Clostridium botulinum" by Emile Pierre van Ermengem. Modern botulinum toxin treatment was pioneered by Alan B. Scott and Edward J. Schantz in the early 1970s, when the type-A serotype was used in medicine to correct strabismus. Other preparations of the type-A toxin were developed and manufactured in the United Kingdom, Germany, and China, whereas a therapeutic type-B toxin was prepared in the United States. To date, the toxin has been used to treat a wide variety of conditions associated with muscular hyperactivity, glandular hypersecretions and pain.

Botulinum toxin: historical perspective and potential new indications.

Botulinum toxin (BTX), a purified form of the neurotoxin responsible for botulism, is used worldwide for the treatment of abnormal muscle contractions. The ability of BTX to block acetylcholine release in a long-lasting but reversible fashion with few side effects has made it an important tool in a wide variety of neuromuscular disorders, including the dystonias, tremor, tics, and spasticity. There are seven antigenically distinct toxins. BTX-A has been in clinical use for almost two decades, with an outstanding efficacy and safety profile. Clinical effects are often seen within 1 week of injection, and benefits typically last from 3-6 months. Patient selection and the proper choice of dose and administration site are the most important determinants of a favorable response to BTX treatment.
