botulínica Toxin

Of a time to this part, the botulínica toxin injections compete with the aesthetic surgery as fashionable method to erase the tracks that the passage of the years leaves in the face.

Nevertheless, the version purified and synthesized of this neurotoxic substance produced by the bacterium cause of the botulism not only has demonstrated to be useful with aesthetic aims.

The Nineties were witness of the diversification of its use for the treatment of numerous neurological affections that they require of a controlled muscle weakening certain.

It is as well as today the botulínica toxin is used for the treatment of the cerebral paralysis, the espasticidad or badly of Parkinson, while the investigators study the possibility of using it to fight the migraines and migraña.

?The beginning of the medical use of the botulínica toxin goes back back to 15 years - doctor Oscar Gershanik counts, head of the Section of Abnormal Movements of the French Hospital. First in using it they were the ophtalmologists for the cases of estrabismo; they discovered that the toxin was effective to inhibit the muscular contraction that causes this ocular deviation.?

He was then that the neurologists asked themselves if he could be applied in other diseases in which also an exaggerated muscular contraction exists. ?It is so it begins to be used first in distonías, that is diseases characterized by a muscular contraction that causes abnormal positions and movements, mainly in blefaroespasmo, that is the contraction of the eyelids, the jaw and the neck.?

With the passage of the years, the neurologists were incorporating new indications for the toxin. ?In the last six years it has been begun to use in espasticidad, cerebral paralysis and Parkinson?, comments.

On the other hand, today also this drug is used to fight diseases that no longer require a controlled muscular weakening, but the inhibition of the transmission of the impulse between the nerve and the muscle.

An example of this new therapeutic direction is the treatment with toxin of the people whose salivary glands (of the mouth) or sudoríparas (of the armpits, palms of the hands and plants of the feet) works in excessive form. According to Gershanik, ?these cases go beyond the aesthetic problem, because they give rise to the marginalization and to the isolation of the individual?.

The most recent uses of the toxin - still in study, but with promissory results they are the treatment of the tensional migraines and migraña.

Perhaps within a pair of years, the botulínica toxin happens fashionable in the doctor's offices of aesthetic clinic; of which we can be safe is that for that then neurologists some new use will have found him.
