Treating my toenail fungus…what about all my shoes?

A lot of patients with toenail fungus inquire on what they can do to save their shoes. After all, many patients have “multiple, can’t be without, spent a lot of money and hardly worn” shoes in thier closet!

Introducing Sterishoe. Accepted by the American Podiatric Medical Association, it looks like a shoe stretcher and is available based on your shoe size. The device contains a germicidal ultraviolet light (UVC). This technology is well known to hospitals and water treatment systems. UVC is clinically proven to destroy microorganisms. The Sterishoe is the first ultraviolet shoe sanitizer that utilizes UVC inside a shoe.

How does it work? It’s simple. You insert the SteriShoe into your shoe. As slight compression is applied, the treatment begins as the UVC rays are activated. If compression is reduced, the light automatically turns off.

Since UVC can be harmful if you look at it too long or hold it close to your skin, Sterishoe provides two important safety measures to protect you. A compression sensor and an ambient light sensor. This way, if the shoe sanitizer is removed from the shoe, the compression sensor will automatically turn off the power to the lamp.

To treat open toe shoes or sandals, there are two shoe bags that are provided. If the ambient light sensor detects too much light, the sanitizer will turn off automatically.
The sanitizer should be applied after wearing the shoes. This way, microorganisms are eradicated and you have healthy feet!

Running With Diabetes

Diabetes is a disease that affects a person’s blood glucose levels which may lead to a large array of complications. According to the American Diabetes Association over 23.6 million Americans or 8% of the US population has Diabetes. Type 2 Diabetes, also known as adult-onset, is the most common form of diabetes and most commonly occurs in adults who are overweight. One of the recommendations given to type 2 diabetes patients is to watch their diets and exercise in order to control their weight. Since running is a sport that does not require much coordination, is relatively inexpensive, and is accessible to everyone, it is a popular choice for diabetics to try and get their bodies into the healthiest shape they can.

If you have Type 1 diabetes then you rely on insulin injections in order to convert glucose into energy to get you through the day. Running with Type 1 Diabetes can be very tricky, but it is definitely do-able and beneficial. The trick to running with Type 1 Diabetes is making sure that you have enough energy, or insulin, to sustain you through the entire run. You will want to ask your physician how long of a run they advise.

If you have Type 2 Diabetes, then your body either does not have enough insulin or the cells do not recognize insulin properly. Therefore these people require that they regulate their diets so that they have the optimal amount of glucose in their systems. If you are a runner that has Type 2 Diabetes then you might have to bring extra little energy packs with you on long runs as well as your blood glucose meter to make sure that your blood glucose levels are being sustained throughout your run. Again, for the best advice on what levels of running are safe for you if you are suffering from type 2 diabetes, consult your physician.

Diabetes is a disease that is becoming an epidemic due to our increasing sedentary lifestyle and the increasing number of people who are acquiring this disease. Running is a great option for people with diabetes to get into the best shape they can to help manage their diabetes. The key thing to remember is that when you run, your body is working much harder than in your normal daily activity. Your blood glucose levels will have to be strictly monitored to ensure you stay as healthy as possible.

Exercise Encouraged With A Good Diet

Exercise has long been considered an important method to improve and prevent diabetes. It has been shown in multiple studies to improve blood sugars and it improves insulin sensitivity. The method of this improvement includes exercise inducing proliferation of glucose-transport molecules that then move to the cell membrane. In a recent study, however, vitamin supplements with vitamin C and vitamin E blunted this effect. It was found that with these supplements insulin sensitivity was not improved with exercise. Better than supplements, therefore, would be the diet rich in fruits and vegetables to continue to improve insulin sensitivity with exercise.

Save a Leg, Save a Life

One of the many complications associated with diabetes is the presence of diabetic foot ulcers. These ulcers are open wounds that are slow to heal, and affect roughly fifteen percent of all diabetic patients. Often the wound is explained by a loss of sensation in the foot, and the patient can not feel that there is an open sore on the bottom of their foot, and may not see it, either.

When the ulcers become infected, which is usually the case; the infection can quickly spread to the other tissues. This can lead to infections of the bone (osteomyelitis) or of the blood (sepsis). Complications due to diabetic foot ulcers will often lead to amputations or even death.

On average, a lower extremity amputation will cost close to $50,000 annually. This cost is mostly from hospital stays and aftercare related to the surgery. Of the patients that do have an amputation, less than 50% will be able to walk with a prosthesis following a below the knee amputation, and less than 25% will be able to walk with a prosthesis following an above the knee amputation. Without the ability to move around on their own, many patients become institutionalized, which can cost upwards of $100,000 per patient. With a 25% reduction in the amount of lower extremity amputations each year, over $4 billion would be saved annually.

Save a Leg, Save a Life is an organization that is devoted to educating doctors and the public on the ways to address these issues. The organization is an interprofessional team, made up of podiatrists, vascular surgeons, nurses, and many other types of doctors with an interest in wound care. The organization seeks to provide information about the advanced methods of treating wounds, including new materials and technologies used in the treatment of diabetic foot ulcers.

Health care providers and health insurance companies are becoming more and more dependent on evidence based medicine as a foundation for treatment. Through Save a Leg, Save a Life, that information is being dispersed through the medical community. Products that are designed to help regenerate healthy tissue and promote healing are replacing the old methods of washing the wound with saline solution. However, these old methods are all that many doctors know, and so they become the standard in wound care. Through programs like Save a Leg, Save a Life, as well as the American Academy of Wound Management and the College of Certified Wound Specialists, hopefully the more advanced methods will become the new standard.

How Should a Diabetic Foot Ulcer be Treated?

The primary goal in the treatment of foot ulcers is to obtain healing as soon as possible. The faster the healing, the less chance for an infection.

There are several key factors in the appropriate treatment of a diabetic foot ulcer:

•Prevention of infection.
•Taking the pressure off the area, called “off-loading.”
•Removing dead skin and tissue, called “debridement.”
•Applying medication or dressings to the ulcer.
•Managing blood glucose and other health problems.

Not all ulcers are infected; however if your podiatric physician diagnoses an infection, a treatment program of antibiotics, wound care, and possibly hospitalization will be necessary.

There are several important factors to keep an ulcer from becoming infected:

•Keep blood glucose levels under tight control.
•Keep the ulcer clean and bandaged.
•Cleanse the wound daily, using a wound dressing or bandage.
•Do not walk barefoot.

For optimum healing, ulcers, especially those on the bottom of the foot, must be “off-loaded.” Patients may be asked to wear special footgear, or a brace, specialized castings, or use a wheelchair or crutches. These devices will reduce the pressure and irritation to the ulcer area and help to speed the healing process.

The science of wound care has advanced significantly over the past ten years. The old thought of “let the air get at it” is now known to be harmful to healing. We know that wounds and ulcers heal faster, with a lower risk of infection, if they are kept covered and moist. The use of full strength betadine, peroxide, whirlpools and soaking are not recommended, as this could lead to further complications.

Appropriate wound management includes the use of dressings and topically-applied medications. These range from normal saline to advanced products, such as growth factors, ulcer dressings, and skin substitutes that have been shown to be highly effective in healing foot ulcers.

For a wound to heal there must be adequate circulation to the ulcerated area. Your podiatrist can determine circulation levels with noninvasive tests.

Diabetes and Foot Surgery

One remark I hear frequently from my diabetic patients is that they have the belief that since they are diabetic, they cannot and should not have foot surgery. Is this true?

Let me answer this question by giving an example of a patient I saw in my office recently. She was referred by her primary care doctor for evaluation of sores on the ends of the third toes of both feet. When I first saw her, it was instantly evident that she had some serious problems. Not only were sores (ulcers) present on the ends of the third toes on both feet, but those same toes were red and swollen - classic signs of infection. I also noticed that she had severe contractures of the second, third and fourth toes of both feet. This caused her to put excessive pressure on the ends of the toes. It was this pressure that ultimately caused the ulcers to form, and became a hindrance in the healing of her ulcers. Further testing showed that not only did she have infected ulcers on both feet, but that the infection had progressed to the bone. After a lengthy discussion with her, we decided that it was best to remove the infected portions of the toes. For a podiatrist, this is not the kind of surgery that we want to perform, but sadly at times must be done.

Since her surgery, she has gone on to heal well, and what is left of the third toes on both feet is healthy and shows no signs of problems. However, she has since developed an ulcer on the fourth toe of the right foot. Again, because of the severe contracture of the toe (also known as a hammertoe), excessive pressure on the end of the toe has caused the skin to break down and ulcerate. So, we are back to fighting the battle to save her toe.

I gave this example to illustrate why surgery in diabetics is sometimes not only permissible, but can turn out to be a way to prevent more drastic complications at a later date. In the case of this patient, my plan now is to perform surgery on the remainder of her hammertoes in order to straighten them. This is not so that her feet will look better (although they undoubtedly will will better), but rather to remove deformities that are causing excessive pressure and make her prone to ulceration, infection, and potential amputation.

So, when can and should a patient with diabetes have surgery? In my mind, diabetes in and of itself does not mean that surgery is not possible. Rather, I look at the patient as a whole and determine if he/she is healthy enough to withstand the surgery, and heal properly afterwards. Things that your podiatrist will look for when contemplating foot surgery include the status of the circulation to your feet. This may involve not only an examination, but also non-invasive testing as discussed by Dr. Wishne in a prior post on this blog. In addition, your podiatrist will want to know how healthy you are in general. How is your heart functioning? How are your kidney's functioning? How well is your diabetes controlled? These and many other factors will be considered before surgery is contemplated.

Your podiatrist has had the advantage of seeing many patients who have developed diabetic foot ulcerations, and he knows the types of feet that are prone to develop such ulcerations. If your podiatrist feels that you are at an increased risk for developing a foot ulcer because of your foot deformity (including hammertoes, bunions, bone spurs, ingrown toenails, etc.), he will be doing you a big favor in recommending procedures that can prevent later complications. Every procedure in medicine has potential risks and benefits. The trick is to determine if the risk of surgery is less than the potential benefits that the surgery will offer. For most patients, pain is a major motivating factor to proceed with surgery. In a diabetic patient who may have neuropathy, prevention of future complications rather than the presence of pain is the main reason to proceed in many instances. This is a decision to be made jointly by you and your podiatrist.

Why Do My Legs Hurt?

Peripheral arterial disease (PAD) is becoming more and more prevalent in America. Our love of fast food and convenience has lead to almost 10 million Americans to be diagnosed with PAD. Our body naturally starts forming plaques in our arteries. This is part of the aging process. Unhealthy lifestyles though cause abnormal increases in plaque and as we get older, these high levels of plaque hardens and causes narrowing of the blood vessels. Arteries supply the body with blood rich in oxygen. If the vessels narrow, the body is not getting the appropriate amount of oxygen to the organs and muscles. Thus, those with PAD are four times more likely to have a heart attack and almost three times more likely to have a stroke.

Who is at Risk? Those with diabetes have a significant risk in developing PAD. So much so, that the American Diabetes Association recommend everyone with diabetes over the age of 50 should be tested. Other high risk factors are high blood pressure, high cholesterol, family history of heart disease, or being overweight. Smoking will also increase your likelihood of developing PADS by four times.

The first signs and symptoms of PAD are often first seen in the legs and feet. This is why we highly encourage high risk patients to pay close attention to pain, discomfort or open lesions in the legs and feet. One will often feel like their legs get tired or painful when walking or climbing exercise. When experiencing this pain, it will go away with rest. This is termed intermittent claudicating and is a sign that your muscles are not getting enough oxygen. One may also feel numbness or tingling, coldness, changes in color, hair loss on the legs and feet. These are all be signs of a serious problem, but some people who have PAD do not appear with any of these symptoms. Thus it is very important to still get tested if you are at risk.

How to get tested? If you are experiencing any of symptoms above or are at high risk of getting PAD, you should consult a health care provider. Testing for PAD is noninvasive, pain free, quick and easy! The examiner will either use a standardized machine or manually take your blood pressure on your arm, ankle and other areas on your leg. Significant changes in your blood pressure in your legs and or ankle is diagnostic of PAD.

What to do if you have PAD. It is important to take the steps to adjust your lifestyle to prevent the progression of the disease. It is advised that patients stop smoking, lose weight, and exercise to improve blood flow. All treatment plans should be thoroughly discussed with your doctor to know what options are right for your body. The doctor may prescribe blood pressure medication, encourage physical therapy, and in critical conditions, surgery may be necessary.
Those suffering from PAD are at an increased risk of having several foot issues including non-healing ulcers. PAD patients should visit a podiatrist regularly for foot screenings and management of foot and ankle problems. A growing number of the American population are having foot and leg amputations due to the effects of diabetes and PAD. Many of these amputations are highly preventable when people take the appropriate steps to care for their feet and consult a podiatric physician when suffering from any foot and leg pain or abnormalities.
