Evaluating the Competency of Your Diabetic Foot Treatment Team: Essential Skill #2: Testing for Diabetic Peripheral Neuropathy in the Feet.

In these discussions, we discuss each of the 7 essential skills that your diabetes treatment team must use in order to help you prevent an amputation related to your diabetes.

Today we will discuss essential skill number two.

2. Test for neuropathy to help determine the risk of ulceration and amputation.

In the simplest of terms, nerves are the wiring system of the body. They carry information from the outer reaches of the body (such as the hands and feet) all the way back to the brain where this information is processed. One thing that wires and nerves have in common is that they both transmit electrical signals. However, it is probably not a surprise that by comparison, electrical wiring system is significantly simpler than a nervous system.

There are a number of processes that happen within the body that can affect the function of nerves. In the diabetic patient in particular, this includes the way the body is using insulin, levels of blood sugar, levels of circulating lipids (or fats in the blood), blood supply to the nerves themselves, and energy metabolism with in the nerve cells that make up an individual nerve.

Although there are many different processes which can damage nerves, high circulating levels of blood sugar are likely the most damaging. In the United States, diabetic peripheral neuropathy (nerve damage in the feet related to high levels of blood sugar) is the most common type of sensory nerve damage.

Although the nervous system is very complex, checking for nerve damage can be remarkably simple. The most reliable test in order to evaluate whether or not a diabetic patient is at risk of developing neuropathic ulceration that might lead to hospitalization or amputation of the leg can be done in only a few minutes and at very low cost. Because of this, it is absolutely inexcusable that a doctor treating a diabetic would not evaluate the function of the nerves in the feet.

In addition to being low cost and simple to perform, there is one test that is the most useful of all exams in determining whether or not a patient is at risk of developing a problem that might lead to a diabetic foot amputation.

This test is called the Semme’s-Weinstein 5.07 monofilament test. In this test, a 5.07 mm diameter monofilament wire is used to apply precisely 10 grams of pressure to the skin of the diabetic foot in order to determine whether or not
the patient has what is known as “protective sensation”.

During this test, the doctor will ask you to close your eyes. He or she will then touch different parts of your feet with this monofilament asking you to say “right” or “left” whenever the doctor touches either of your feet.

If you can feel every area where the doctor touches your feet, you are at low risk of developing a diabetic foot ulceration that might lead to amputation.

If you do have some loss of sensation, the damage is usually at the ends of the longest nerves in the body. The longest nerves of course happen to go from the spinal cord all the way down the legs and out to the end of the toes. Because of this, the damage seems to appear in what doctors call a “stocking glove distribution pattern.” This means that the damage occurs starting the end of the toes and will usually stop in the same area on both feet as if one has rolled socks on to both feet at the same time.

For example, someone may have lost all of the sensation in the toes, but has all of the station present in the ball of the foot. This means that the patient is at risk of having an open sore develop in the toes but less likely in the midfoot or ball of the foot.

Because this can get worse over time, it provides a good baseline to determine if the diabetic foot problems are staying the same or getting worse.

The implications of this test are that if you have lost “protective sensation,” you are at high risk of starting to develop a blister and not being able to feel that there is a problem. The patients that have this sort of nerve damage will oftentimes step on foreign objects such as splinters, thumbtacks, or slivers of glass and never even noticed that anything has happened. It is this type of open sore that can rapidly develop into an infected diabetic ulceration and later lead to a diabetic foot amputations.

There are a number of other tests that can be used to evaluate the function of the nerves in the diabetic foot. Simply touching a specific type of vibrating tuning fork to the feet and ankles can get a great deal of information about early nerve damage that may be present but not yet concerning for the kind of damage that can lead to open sores.

Other screening tests that your doctor might use include checking hot/cold sensation, two-point discrimination, and evaluating light touch sensation. Nerve conduction velocity exams are more invasive tests and should be reserved for those with indications of problems such as tarsal tunnel syndrome.

Even if there is nerve damage, the open sores that result primarily from existing nerve damage are still mostly preventable. It just requires a little extra vigilance on the part of the patient and the doctor.

If there is only one screening test is performed your doctor evaluating your risk of foot problems that could lead to an amputation, it is the SWMF 5.07 test. For this reason, you must make sure that your diabetic foot doctor checks your feet initially to determine your risk of developing the sort of problems.

Only then will you know whether or not you are at imminent risk of and amputation.

One Fourth of Diabetic Amputees Wish They Saw a Podiatrist Sooner

A 2008 study conducted by an an independent research firm for the American Podiatric Medical Association found 25 percent of 600 diabetics who were surveyed and had suffered an amputation related to their diabetes said they should have seen a diabetic foot specialist like a podiatrist. Thirty percent of amputees believed that watching closer and heeding known early warning signs, such as “hot spots” and diabetic foot ulcers, might have prompted them to visit their doctor before things worsened.

In total, 75 percent of the survey participants were type-2 diabetic. The remaining 25 percent were considered at high risk for developing the disease, sometime called "per-diabetic" or "bordeline." The study results showed also found that Hispanics were the least likely ethnic group to be tested for diabetes, compared to African-American and Caucasians. Surveye participants said the reason for not getting tested for diabetes was primarily due to normal blood sugar levels or not having noticeable symptoms.

“This survey shows just how immensely important it is for those diagnosed with diabetes, and those at risk, to have their feet examined by a physician during their annual checkup” the APMA president said. “Regardless of one’s ethnic background, taking a proactive approach to your health in asking your physician to check your feet can save both your limbs and your life.”

Gene Therapy may be the Future in Amputation Prevention in Diabetics with Poor Blood Flow

Cardiologists and vascular surgeons at Rush University Medical Center are now studying in innovative but investigational new medication that involves gene therapy. Researchers are working to determine whether or not gene therapy can promote new blood vessel growth in the feet and legs of patients who suffer from critical limb ischemia.

Critical limb ischemia is a condition that results in a severe lack of blood flow to the patient’s feet and legs. This often occurs in patients with diabetes. Peripheral vascular disease and disruptions in blood flow to the feet and legs are a major cause of amputation in the United States. At present, about 70% of all amputations are related to diabetes.

When a patient has diabetes, the process of atherosclerosis which clogs the arteries happens faster. If this process goes on for long enough, critical limb ischemia can develop. Because the arteries become clogged, there is less circulation to the feet and legs.

This results in a lack of oxygen and, in a sense, starves the tissues of nutrients. Without nutrients, the tissue start to die off and ulcers (or diabetic foot sores)can develop. “The goal of gene therapy is to stimulate the growth of new blood vessels. The additional blood vessels will carry more blood into the legs, alleviating pain and healing ulcers,” one of the researchers said.

The research is presently being done at Rush University involves Phase III clinical trials which will evaluate the effectiveness of gene therapy in preventing amputations in people with critical limb ischemia.

At present there are no prescription drugs at all available which can effectively treat critical limb ischemia. Because there are so few interventions that are effective, new therapies are needed in order to prevent the sorts of amputations.

This type of gene therapy is known as angiogenesis therapy, which means growth of new blood vessels. This sort of gene therapy appears to induce the production of a protein called fibroblast growth factor (FGF-1) which stimulates the growth of blood vessels at the site of injection.

The clinical trials that are now under way will last for one year. Participants are over 50 years of age, have stable ulcerations of the skin and noninfected gangrene on a foot or leg. All have also been diagnosed with peripheral arterial disease and critical limb ischemia. The participants will receive for injections of the investigational medication or a placebo into the leg muscle a two week intervals.

It is known that about 8 million people suffer from peripheral arterial disease. In the United States, that means one out of every 40 adults. It is a very common disease. It is often underdiagnosed. Because it is so common in diabetic patients, this might provide new hope for the prevention of diabetic foot amputations.

UNC Basketball Player: Diabetic Foot Amputation?

The Asheville Citizen just reported that UNC Asheville basketball player Kenny George has been released from the hospital after having a foot amputation. Although the patient and his parents have declined comment, is suspected that this was a similar episode was expected with diabetes and amputations.

What we do know is that the 7-foot-9, 375-pound center had to have part of his right foot amputated earlier this year. As part of that treatment he also spent three months in the hospital. The reason for such a prolonged hospitalization and amputation was that he contracted MRSA.

MRSA (or methicillin-resistant Staphylococcus aureus), is a type of bacterial infection, which is resistant to many antibiotics. This is now a much feared complication of hospitalization and surgery performed in hospitals throughout the United States. About 10 years ago, the vast majority of these infections were contracted while patients were in the hospital. Today these infections are growing more and more common. In some communities 85% of all skin and soft tissue structure infections involve the drug-resistant bacteria.

Because these bacteria have become more resistant to most of the antibiotics that are taken by mouth, it is often necessary for a patient to be hospitalized in order to treat the infection. These intravenous (I.V.) antibiotics are typically very expensive. Often times the antibiotics can cost $1000 per day. If these infections move into the bone, surgery and up to six weeks of antibiotics can be necessary.

In diabetics, the only effective way to reliably treat these infections is through amputation of the foot. Diabetes substantially reduces a person’s ability to fight off one of these infections. MRSA infections are much more common in people with diabetes. Recent research has shown that about 70% of all amputation to related to diabetes. Although it is not clear that this basketball player is diabetic, it is certainly unusual for a non-diabetic patient to end up with a sort of problem particularly at a young age.

At the end of November, the patient was released from the hospital and is at home recovering. It is hoped that the infection has now been completely cleared.

National Health Service Increases Funding for Diabetic Foot Programs Related to Podiatry

Children with diabetes in certain areas of the United Kingdom will be getting extra financial support.

The National Health Service has recognized the critical nature of funding diabetic programs for children. His most recent funding will help to pay for pediatric diabetic nurses as well as psychological support for children with type 1 diabetes. It is known that type 1 diabetes in children is linked with high levels of depression as well as eating disorders.

In addition to counselors who specialize in diabetes related to children and pregnancy, extra podiatrists have been added as well. For many years podiatrists in the United Kingdom have been recognized as critically important to preventing complications lead amputation. They have recognized that intensive monitoring by foot and ankle specialists, particularly podiatry, lead to early interventions and help to provide rapid treatment for diabetic foot ulcerations and open sores that can lead to amputation.

It has long been known that open sores in diabetic patients can rapidly become infected and lead to gangrene. Is also known that bone infections known as osteomyelitis are typically preceded by diabetic foot ulcers.

The hope of the additional funding is that diabetic patients will taking off of waiting lists and will be able to be evaluated sooner.

In addition to funding for type 1 diabetic patients, there’s a great need to assist with those with type 2 diabetes. Type 2 diabetes is becoming increasingly common. This rising type 2 diabetes, directly correlates with the increase in obesity within any given population.

At present, approximately 10% of the entire National Health Service annual budget is spent on treating diabetic foot ulcers, open sores on the feet, diabetic foot infections, and other diabetic foot complications.

Is well known that by having patient work closely with their primary care doctors and podiatrists, it is easier to keep diabetes under control and prevent diabetic foot amputations. It is also important to make sure that they podiatrist is closely involved one of diabetic patient begins a new program of exercise to help control the persons blood sugar.

Diabetes is not have to lead to amputation. With good blood sugar control, proper diet and exercise, diabetic patients can hope to lead a healthy and active life.

Diabetic Foot Infection... Emergency Surgery as it Happened Today

Today was one of the days I dread. I was coming out of a treatment room and Sherrie stopped me to ask if we could ad an emergency diabetic patient. A diabetic man man was on the phone. He had called and said his big toe was "black and blue and squirting blood." Never a good sign. I told Sherrie to tell him to either come in immediately or go straight to the Emergency Room.

Twenty minutes later he was in my podiatry office sitting in a treatment room. He was right, it was black and red. But squirting more pus than blood. I started to trim a way some of the thick hard callus to drain the infection. And drain it did, odor and all. Paula, who was assisting me, asked to leave the room.

I explained that he was going to need surgery. I had him sign a consent form and explained what we would need to do. I took some cultures, wrapped up the foot and sent him straight to the hospital to be admitted for powerful antibiotics and to get ready for surgery. I sent over some orders and then saw the rest of the patients.

After I finished seeing all of the post-op bunion patients, heel pain cases, and a guy that almost lost his toe a year ago, I went home to eat with my wife and son Alex. He's going to be a year old next week. We ate dinner and I waited for the hospital to call, to tell me when we could start. After Alex went to sleep, I headed back to the hospital.

In the operating room, I took a scalpel and opened the end of the big toe. The bone in the end of the toe was mushy and soft. I took some pieces to send for culture (to see what kind of bacteria is growing in there). I removed the bone and flushed it out to wash away the pus and bacteria. I packed the end of the toe and wrapped it up.

In a few days we will go back to the O.R. and remove whatever looks dead or infected. Or if all is well, I will close it so he can go home for Christmas.

The reality is that this episode was preventable. With proper monitoring and careful attention to the feet, this man would not be in the hospital. I would have been at home with Alex. He would have been home with his family instead of in the hospital.
