Botulinum toxin injections are one approach to the treatment of muscle spasticity. These injections can be given with ease and have minimal side effects. They can also be used in very focal spasticity problems that involve a few muscle groups. This treatment may not be right for some patients, such as patients with severe, widespread muscle spasticity, and patients with permanent muscle contractures that have become rigid.
Botox was introduced to the world in the late 1980s by ophthalmologists, who began using it to treat optic muscle disorders. It was approved by the Food and Drug Administration (FDA) for the treatment of moderate to severe frown lines between the eyebrows (glabellar lines) in 2002, and its popularity has soared ever since. Botox is consistently one of the top five nonsurgical cosmetic procedures performed each year.
Some doctors and dermatologists recommend lying down and resting after a treatment, but Ravitz says she doesn't think there's any need for downtime unless a patient experiences pain. It can take about two weeks to work, though some patients start to feel relief from chronic migraines sooner than that. Ravitz tells me, "If it’s going to work for a patient, one round of the treatment typically lasts for around three months." Though everybody metabolizes it at a different rate, getting it done every three months or so has been found to be effective.
Most practices have a flat cost for each injection of BOTOX® Cosmetic, though some will break it down by “units” used per treatment. Flat rates are usually somewhere between $300 and $1000, while per-unit rates are usually around $10-15 per unit. Though the BOTOX® Cosmetic price paid by physicians is normally about $400 for each vial (each vial contains 100 units, or enough for about 4 or 5 treatments), the vial must be used within a few hours of opening, so if the entire vial is not used, the physician will often have to throw the rest out.
This is because the discretionary procedures tend to be out of pocket, and providers are used to answering the question: how much does it cost? An MRI, on the other hand, might have several prices: A sticker price, a negotiated or reimbursed rate (what the insurance company pays), the rate that Medicare and Medicaid pay for treatments for people who are older and those who have low income, an out-of-network price, and so on. We know about this because we’ve done pricing surveys for about 35 common procedures in seven U.S. metro areas, collecting cash or self-pay prices for both medically necessary procedures (an MRI, a colonoscopy) and discretionary procedures (Botox, Lasik).
The toxin itself is released from the bacterium as a single chain, then becomes activated when cleaved by its own proteases. The active form consists of a two-chain protein composed of a 100-kDa heavy chain polypeptide joined via disulfide bond to a 50-kDa light chain polypeptide. The heavy chain contains domains with several functions: it has the domain responsible for binding specifically to presynaptic nerve terminals, as well as the domain responsible for mediating translocation of the light chain into the cell cytoplasm as the vacuole acidifies. The light chain is a zinc metalloprotease and is the active part of the toxin. It is translocated into the host cell cytoplasm where it cleaves the host protein SNAP-25, a member of the SNARE protein family which is responsible for fusion. The cleaved SNAP-25 is unable to mediate fusion of vesicles with the host cell membrane, thus preventing the release of the neurotransmitter acetylcholine from axon endings. This blockage is slowly reversed as the toxin loses activity and the SNARE proteins are slowly regenerated by the affected cell.
But even if the laws remain unchanged, as long as off-label uses are permitted by law, expect doctors to keep pushing the boundaries of Botox's applications--sometimes in the name of medical progress and sometimes with remarkable results.Norman Rosenthal, the Maryland psychiatrist who recommended Botox for his suicidal patient, says he's seen the upside firsthand. The patient, persuaded by Rosenthal, did indeed get Botox shots on his forehead and between his brows. Days later, Rosenthal got an email from the patient. It was a thank-you note. Finally, the patient wrote, he was feeling better.
After working out techniques for freeze-drying, buffering with albumin, and assuring sterility, potency, and safety, Scott applied to the FDA for investigational drug use, and began manufacturing botulinum type A neurotoxin in his San Francisco lab. He injected the first strabismus patients in 1977, reported its clinical utility in 1980, and had soon trained hundreds of ophthalmologists in EMG-guided injection of the drug he named Oculinum ("eye aligner").
Other potential adverse events that may occur with breast implant surgery include: asymmetry, breast pain, breast/skin sensation changes, capsular calcification, delayed wound healing, hematoma, hypertrophic scarring/scarring, implant extrusion, implant malposition, implant palpability/visibility, infection, nipple complications, redness, seroma, swelling, tissue/skin necrosis, wrinkling/rippling.
“Botox is a completely cosmetic procedure, so if and when someone ‘needs’ it is a purely personal decision,” Shah says. “Some people are not bothered by developing fine lines and wrinkles. For those who are, I generally advise starting treatments just when they start to see the lines develop, or when the wrinkles linger even after the movement has stopped.”
The efficacy and safety of BOTOX for the treatment of lower limb spasticity was evaluated in Study 6, a randomized, multi-center, double-blind, placebo-controlled study. Study 6 included 468 post-stroke patients (233 BOTOX and 235 placebo) with ankle spasticity (modified Ashworth Scale ankle score of at least 3) who were at least 3 months post-stroke. A total dose of 300 Units of BOTOX or placebo were injected intramuscularly and divided between the gastrocnemius, soleus, and tibialis posterior, with optional injection into the flexor hallucis longus, flexor digitorum longus, flexor digitorum brevis, extensor hallucis, and rectus femoris (see Table 33) with up to an additional 100 Units (400 Units total dose). The use of electromyographic guidance or nerve stimulation was required to assist in proper muscle localization for injections. Patients were followed for 12 weeks.
Patients with diabetes mellitus treated with BOTOX® were more likely to develop urinary retention than nondiabetics. In clinical trials, 12.3% of patients (10/81) with diabetes developed urinary retention following treatment with BOTOX® 100 Units vs 0% of patients (0/69) treated with placebo. In patients without diabetes, 6.3% of patients (33/526) developed urinary retention following treatment with BOTOX® 100 Units vs 0.6% of patients (3/516) treated with placebo.
Prevention of contractures begins with finding out what is limiting a child from either actively (moving oneself) or passively (being moved by someone else) moving the joints through a full range of motion. In some cases, this can be due to destruction or abnormality of the bones around a joint. It can also be due to problems with the ligaments and tissue around that joint.
Botox is a drug made from a neurotoxin produced by the bacterium Clostridium botulinum called botulinum toxin. "It's a poison secreted by the bacteria," plastic surgeon Norman Rowe, M.D., tells SELF. Botulinum toxin has proven to be a successful and valuable therapeutic protein when dosage, frequency of treatment and variety of treated clinical conditions are considered, according to Howard Sobel, M.D., a dermatologist in New York. Basically: when it's done right. When it's done wrong—like, really, really wrong—it can cause "botulism-like symptoms," according to Mayo Clinic, which may include muscle weakness, trouble breathing, speaking or swallowing, bladder control issues, and vision problems. That is "very unlikely," but a more than convincing enough reason not to go bargain hunting for Botox.

According to the PREEMPT paradigm, one injection of 5 units of onabotulinumtoxinA into four sites (total 20 units) into the frontalis muscle is done. The injection points are located by visually drawing a line up from the medial edge of the supraorbital rim. Patients will be injected into the muscle in the upper third of the forehead at least 1 to 2 fingerbreadths above the corrugator injection site. The lateral muscle injection areas are parallel and approximately 1 fingerbreadth lateral to the medial injection site, which is roughly in line with either the midpupillary line or the lateral edge of the cornea, which is the limbus line. In cases in which I am worried about ptosis, I inject the frontalis close to the hairline. In order to reduce the risk of these unwanted effects, injections should be administered in the upper third of the forehead only. The needle should be inserted at a 45° angle superiorly. Because the frontalis is an elevator muscle, weakening can cause brow ptosis or exacerbate preexisting brow ptosis.
The potency Units of BOTOX® are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, Units of biological activity of BOTOX® cannot be compared to nor converted into Units of any other botulinum toxin products assessed with any other specific assay method.

BOTOX blocks neuromuscular transmission by binding to acceptor sites on motor or sympathetic nerve terminals, entering the nerve terminals, and inhibiting the release of acetylcholine. This inhibition occurs as the neurotoxin cleaves SNAP -25, a protein integral to the successful docking and release of acetylcholine from vesicles situated within nerve endings. When injected intramuscularly at therapeutic doses, BOTOX produces partial chemical denervation of the muscle resulting in a localized reduction in muscle act ivity. In addition, the muscle may atrophy, axonal sprouting may occur, and extrajunctional acetylcholine receptors may develop. There is evidence that reinnervation of the muscle may occur, thus slowly reversing muscle denervation produced by BOTOX.
Botulinum toxin is one of the most poisonous substances known to man. Scientists have estimated that a single gram could kill as many as 1 million people and a couple of kilograms could kill every human on earth. In high concentrations, botulinum toxin can result in botulism, a severe, life-threatening illness. Botulism, left untreated, may result in respiratory failure and death. Despite botulinum toxin being so toxic, Botox is in huge demand.
