Peripheral Nerve Damage From Trauma

Peripheral Neuropathy Overview Full Information and Treatment of Peripheral Neuropathy

Peripheral Neuropathy is a commoncondition occurring when injury or disease damagesyour peripheral nervous system originating from your brain and spinalcord peripheral nerves extends to your skinmuscle and tissues or peripheral nervous system relaysvital information between your body and the brain in theform of electrical impulses there are three types of peripheralnerves motor nerves regulate the movements loveyour body skeletal muscles

sensory nerves transmit sensations such as heat vibration touch and pain to the brain comic nerves regulate the activities upinternal organs and glands each nerve is made up of manyinterconnected cells called neurons that transmit impulses at lightning speed this constantexchange allows your brain to respond to vitalinput from your body

however damage to the nerves disruptsthis critical link resulting in peripheral neuropathy damage to a single nerve called MononaRobert B usually results from injury orrepetitive stress an example %uh Monona Robert E is carpaltunnel syndrome repeated impact to the nerve in yourwrist may cause tingling pain and weakness in your hand arm and shoulder

government have multiple nerves calledPaulina Robert the is far more common damaged typically begins in the nervesfarthest from the central nervous system and progresses symmetrically Paulina Robert the can be caused bydiabetes and other systemic diseases infections or exposure to toxic substances

one or all the three nerve types may be affectedand symptoms are specific to each damage to sensory nerves characteristic have diabetes can lead to numbness inyour hands and feet with diminished ability to detecttemperature insensitivity to pain or over sensitivity to pain Paulina Robert the may also cause damageto your motor nerves

which can result in muscle weakness twitching and pain common signs %uh nerve damage include intolerance to heat loss of bladder control gastrointestinal disturbances impairment a breathing

Seeing Pain New approach to diagnosing and treating nerve damage Chris McCurdy TEDxUM

When I was a young childI lost my favorite uncle to alcohol abuse. It made me wonder why does this happen? How can someone be consumed by a substance that's around us all the time? So, I made it my life's missionto become a drug expert, and I went to pharmacy school. I went to pharmacy schoolto understand what it is about drugs

that can make us heal or can hurt us. When I was in pharmacy school, I found out I fell in lovewith the research. Not only did I fall in lovewith the research I fell in love with this passionto educate others. And so, knowing that,I had to move forward. I had to move forward with my education so that I could carry those thingsout of my future;

and I went on and earned a atein medicinal chemistry; that's drug design not designer drugs. (Laughter) That enabled me to move forward and really pursue some of the basisof drug abuse and addiction. Here I am now, a professorof medicinal chemistry and pharmacology. And I've dedicated my careerto solving problems in drug abuse and actually findingbetter pain medications

because after all, painis the most common reason that individuals seek medical care. It's also the most common reason that we end upwith drug abuse and addiction. Moving from there, I've been ableto establish a laboratory here, at the University of Mississippi, where we've done a lotof groundbreaking work that I'll get to in a little bit to move us forward in those endeavors.

Now, how many people here have had to seek medical treatment that resulted in pain prescription? Yes, most all of us. How many of you ended up getting something like morphine, or codeine,or Hydrocodone, or Oxycontin? Yeah. Any of you had to take that for more than 2 or 3 weeks,maybe a month, maybe a couple?

If so, there's a high likelihoodyour body became physically dependent. So why does that mean? What do we mean when we talkabout physical dependence and drug abuse? Let's define these thingsa little more clearly. So drug abuse is simply the concept that you take a drug out of the contextthat it was prescribed. So, every now and then,all of us are guilty of taking a little more ibuprofen,or something, than it says on the bottle.

Helping the body regrow nerves Science Nation

♫MUSIC♫ MILES O'BRIEN: Combat, cancer and accidents all can cause devastating nerve injuries. Sometimes, the body heals on its own. CHRISTINE SCHMIDT: Your peripheral nerves are the ones in the arms and the face, have an inherent ability to regenerate but only under ideal circumstances. MILES O'BRIEN: With support from the National Science

Foundation, University of Florida Biomedical Engineer Christine Schmidt is working to restore nerve function when injuries are more complicated. SURGEON: Took that muscle and rotated it, took it over the back of his elbow to cover – MILES O'BRIEN: Surgeons can sometimes move a nerve from one part of a patient's body to another. Schmidt has developed a method that grafts cadaver tissue onto the damaged area to

act as a scaffold for nerves to regrow themselves. CHRISTINE SCHMIDT: Basically what we're doing is removing all the cellular material that would cause rejection but leave behind the native architectures. You're putting this graft into the site of injury. And now, that graft is providing a scaffold for your blood vessels to grow in. And then once you have that recellerization your nerve fibers can then regrow, so then, ultimately regain that muscle function.

MILES O'BRIEN: Navy Veteran Edward Bonfiglio, wounded in Afghanistan, faced the prospect of an amputation. A graft was a welcome option. The company, AxoGen, distributes the grafts, which were developed based on work done in Schmidt's lab. JILL SCHIAPARELLI: And his family pressed the s to say, quot;Are there any alternatives?quot; He was a young, healthy, vibrant guy. And they had a great surgeon at Walter Reed who was willing to work with them to find those options.

CHRISTINE SCHMIDT: This is some of the micronized nerve that you're working with. MILES O'BRIEN: Schmidt and her team are also looking at other approaches to directly stimulate nerve growth using natural sugar molecules found in the body as building blocks, eliminating the need to transplant tissue. CHRISTINE SCHMIDT: So you don't have to actually take it from somebody's body. You can grow it.

MILES O'BRIEN: While the ultimate goal in nerve regeneration is reversing paralysis, Schmidt says intermediate successes, like improving lung or bladder function, can be invaluable to patients and their families. CHRISTINE SCHMIDT: So rather than saying we're going to try to tackle this humongously complex beast and try to get the patient to necessarily be exactly like they were before, why not provide some function that will have merit
