Dad is in having spine surgery right now for several bad disks that have gotten tangled up around the spinal nerves. Before surgery, they told us the surgeon would be monitoring him to make sure things don’t go bad. I guess he could end up paralyzed if something went wrong. I’ve been searching on-line about this business and found that not all surgeons do this because it’s not really accurate. What can you tell me about this monitoring?

Neuromonitoring techniques have been developed to help reduce the risk of permanent paralysis during spinal surgery. In a case like this with nerve tissue involved, it can be very complex and challenging to clean up the area without cutting into the nerve or in some cases, the spinal cord itself.

The use of neuromonitoring is an area of controversy in spinal surgery. This is a way of detecting whether or not the patient is in immediate risk of damage being done to the spinal cord or spinal nerve roots. The surgeon can either wake the patient up and test him or her for normal sensation and movement or use a special device that monitors the patient’s neurologic status.

The wake-up test isn’t very practical because it doesn’t measure what’s going on from moment-to-moment. In other words, you can’t keep waking the patient up every minute to find out if everything is okay.

On the other hand, the use of tests such as electromyography, somatosensory evoked potentials (SSEP), and motor-evoked potentials (MEPs) can produce false negatives. A false negative means the test is negative indicating no problem when the patient is really compromised and in danger of paralysis. False negatives can be very serious.

According to a recent study, about 65 per cent of all spinal surgeons do make use of some form of neuromonitoring. The goal is to prevent (and reduce) the risk of new neurologic problems developing during spine surgery.

Some surgeons use more than one neuromonitoring technique in hopes of improving the chances of avoiding complications. Neuromonitoring for simple cases of disc removal isn’t required. There are times when neuromonitoring is highly recommended such as when implants are being put in place to hold the vertebrae apart or to stabilize the spine.

It’s likely that in your father’s case, there was a real need for neuromonitoring. If you have further doubts, ask his surgeon for a more detailed explanation of the decision to use neuromonitoring.

What can you tell me about bone cysts? And especially aneurysmal bone cysts?

Bone cysts are spaces within a bone that are filled with some type of fluid. Two common benign bone cysts are unicameral and aneurysmal. Unicameral bone cysts are often close to the growth plate next to a joint. They tend to fill up with synovial (joint) fluid.

Aneurysmal bone cysts are more likely to be filled with blood. They affect the long bones (upper arm, thigh, ribs) and back of the spine most often. Aneurysmal bone cysts are considered “benign” meaning they aren’t cancerous and don’t spread. But they can do plenty of damage even causing the bone to break.

The cause of bone cysts remains unknown but there are some theories. Sluggish flow and congestion of fluids, trauma, and local disturbances in blood circulation are some of the more likely causes. There is evidence to support each one of these ideas. Molecular and genetic theories exist as well.

Knowing how bone cysts develop may help with prevention but once they appear, treatment is based more on the natural history and prognosis. Bone cysts don’t usually go away by themselves without some type of treatment. Usually that treatment is surgical removal.

Left alone, they will just get bigger and increase the risk of another bone fracture. If the cyst is large enough, it may be necessary to fill in the empty space (after removal) with a bone graft.

Aneurysmal bone cysts tend to come back even after surgical removal. Efforts are being made to find effective ways to kill any unseen cells left behind. Liquid nitrogen, phenol, and argon beam coagulation are three examples of treatments used to prevent recurrence.

Only a very wide resection (cutting around the edges) of aneurysmal bone cysts has a zero per cent chance of recurrence. Other methods under investigation include arterial embolization. This is a way of injecting blood clots into the blood vessel to close it down and prevent further bleeding.

I’ve had lupus since I was 23. Now at age 40, I have found ways to manage except for my right wrist. I am right-handed and it would be helpful if I could get the full use of that wrist back. Splinting hasn’t helped. Exercises help me stay the same but they don’t improve things — just keep them from getting worse. Any suggestions?

Systemic lupus erythematosus, otherwise known as “lupus” is a chronic inflammatory disease involving many areas of the body. For some (as yet) unknown reason, the immune system attacks the person’s own tissues and organs.

Inflammation caused by lupus can affect many different body systems. Most often the areas involved include the heart, joints, skin, lungs, blood vessels, liver, kidneys, and nervous system.

As you have experienced, joint disease can be severe enough to cause painful loss of motion and function. Quality of life can suffer with this disability. Treatment for lupus often involves medications. These can be very effective in controlling painful joint symptoms.

The best thing to do is get with your physician and review your situation. This is a good time to look back at what has worked well in the past and re-examine treatment options now. There may be some more effective medications available now. Perhaps a slightly different rehab program would help you regain some motion and function.

When chronic inflammation causes joint destruction, then surgery may be needed. In the past, wrist fusion was the main surgical approach to the problem. Today, thanks to modern technology and improved surgical techniques, a total wrist replacement is possible.

Patients with rheumatoid arthritis are the one most likely in need of a wrist replacement. But people like yourself with lupus may find this is a helpful treatment as well.

I really love my Pilates class — I go almost everyday. But I can’t help but wonder if there’s any real scientific basis for this technique. I’ve heard it has been around a long time but I couldn’t find much on the Internet to prove it works. What do you know about it?

You are among many millions of people who would agree with you. Pilates exercise is fun, fascinating, and almost addictive for some people.

Pilates is actually the name of the German born man (Joseph Pilates) who first developed this technique back in the mid-1900s. It was almost a lost art until about 10 years ago. And then the momentum behind the Pilates movement seemed to snowball. The word spread and now it is a technique that is offered in classes at the local YMCA, health club, fitness center and even physical therapy clinics.

Mr. Pilates believed that using his exercise approach, brain cells would be activated and even improve thought processes. His focus on precision, learning coordinated and rhythmical movement patterns, and breathing were meant to be for each individual person. But today’s approach is more of a group training in classes like you are probably taking.

According to a recent review of 90 articles published since 1995, there is a scientific foundation but limited evidence for Pilates. Actually, only nine of the 90 published studies were high enough quality to be considered in the review. But those studies did show that some of the Pilates techniques designed to align, lengthen, and protect the spine are effective in developing strength of the abdominal and trunk muscles.

As it turns out, the combined use of focus, breathing, rhythmical movement, and precision results in total body strengthening (not just the core or central muscles of the abdomen and trunk).

Weaker muscles start to contract and participate in the movement when stronger muscles are engaged. With improved muscle control comes better alignment and protection of the spine. The end result is the ability to perform even more advanced skilled movements with perfect balance and coordination.

Although it is believed that anyone of any age in any condition can benefit from Pilates exercises, research to support this with actual evidence is still lacking. It’s clear that any form of exercise is beneficial for your overall health, so don’t stop what you are doing!

My niece is a physical therapist and a pretty smart cookie. She’s been involved in some studies developing something she calls treatment-based classification. She tries to explain it to me but I think I need a tutorial. Can you help me out? I’d like to keep the conversation she’s interested in going but I’m at a loss here.

As your niece has been telling you, physical therapists have developed a method of examination for patients with low back pain called treatment-based classification.

This three-step approach tries to match symptoms with a treatment approach that works best for those symptoms. Instead of just applying the same treatment techniques to everyone and hoping for the best, this approach is based on research and evidence available so far.

The therapist starts by making sure the patient doesn’t have a serious underlying pathology causing the low back pain. This process is called screening for referral. Anyone with signs of infection, inflammation, malignancy, or fractures must receive immediate medical attention before physical therapy treatment can begin.

Once the patient has been cleared, conservative (nonoperative) care under the direction of the physical therapist is next. During this second stage, the therapist evaluates the patient in order to decide which treatment approach will work best. As part of the process, the patient fills out several surveys that help identify levels of pain and disability.

The athlete is managed using treatments divided up on the basis of three stages. The goal of treatment is to reduce pain, improve function, speed up recovery, and prevent loss of practice and/or play time. Once the stage has been identified, then special tests are performed that have been found reliable in predicting which type of treatment will have the best outcomes. Let’s take a look at the three stages.

Stage I is more acute during the early days following an injury. Usually, this person has difficulty standing, sitting, or walking for very long or very far. Treatment during this stage is often with advice, manual therapy, and specific exercises. The athlete’s posture is modified when appropriate. Core training of the trunk and abdominal muscles help stabilize the lumbar spine.

Stage II describes the patient who can stand, sit, and walk but has trouble with basic daily skills (e.g., vacuuming, lifting, jogging, driving). Stage III means the patient can manage daily activities but isn’t able to participate in sports. Stage III is more of the chronic phase where patients experience recurrence of their low back pain that can be very limiting.

Treatment approaches for these two groups are still under investigation. Though the therapist has many treatment techniques available, predicting which one (or combination of techniques) will yield the best result remains unknown. Some of the treatment intervention will address pain while others focus on flexibility, strength, posture, and aerobic capacity. Endurance and neuromuscular control are also targeted in the more advanced levels of training (stage III).

Athletes in stage III are ready for sports-specific exercises. This approach is called functional training. It moves the athlete from limited practice time back to full participation in the sport of their choice. One of the long-term goals of treatment using this approach is to prevent future episodes of repeated back injury/pain.

To summarize, it sounds like your niece is part of the physical therapists who are busy researching, studying, and developing an evidence-based approach to low back pain. Rather than applying treatment willy-nilly, they carefully examine each patient using a three-step classification-based approach. Staging the patient (stage I, II, or III) based on level of pain, disability, and function helps direct treatment. This treatment-based classification yields a rapid recovery and return to normal activities.

I confess I’m a retired physician with a healthy interest in sports, sports celebrities, and the treatment of sports injuries. For awhile, the new platelet-rich plasma treatment for soft tissue injuries was front and center of all the news media reports. When any big time player got this treatment, we all heard about it. But it seems to have fallen off. What’s the status of this treatment technique? Was it all media hype and bogus or is there something to it?

It turns out that the simple idea of using the body’s own platelets with its powerful growth factors to speed up healing is more complex than originally thought. What started out as a way to remove a person’s own plasma and platelets and inject them into injured tendons, ligaments, or muscles quickly opened up Pandora’s box.

One concern raised by a group of expert scientists who reviewed 5000 published studies on this treatment is the lack of quality control over platelet-rich plasma. There is no way to standardize the product because the body simply doesn’t produce the same amount of platelets every hour of every day in every person. What you eat, how well you sleep, medications you take, and even the exercise you get can all affect platelet levels in the blood.

There’s more than one way to extract (remove) the platelet-rich plasma (PRP) and that can also affect the quality of the product. Other components of the blood (such as white blood cells) may get in the sample used and alter the body’s healing response (not always favorably).

A closer look at the different studies highlighted some of the difficulties in comparing one study to another. That may explain why results can be opposite from study to study. One common theme seems to be that platelet-rich plasma may be most effective for chronic musculoskeletal injuries. It’s not a given that the results obtained in one condition will be the same for another type of soft tissue injury.

Another problem is the wide range of tissue types being treated (e.g., cartilage, bone, tendons, ligaments, muscles). Results seem to differ within the tissue types so that how platelet-rich plasma affects a ligament in the knee may not be the same as the effects on a similar ligament in the ankle.

And a major stumbling block in the research that’s being done on platelet-rich plasma (PRP) is the way results are recorded. Some studies look at patient response in terms of pain levels and activities of living. Others are measuring strength after treatment or speed of wound healing during recovery.

The treatment isn’t bogus at all. It’s just that there are some concerns that need to be addressed before platelet-rich plasma is used for any and all soft tissue injuries. For example, we need to determine who’s a good candidate for this treatment? What kind of conditions can be treated effectively with platelet-rich plasma? How long should we wait after having platelet-rich plasma before resuming normal activities?

Engineering healing with platelet-rich plasma is an exciting area of research and study. If successful, it could result in fast, effective healing of all types of soft tissue injuries. We’re not quite ready for any real treatment guidelines yet but we are a step closer to organizing and directing future studies.

I heard Tiger Woods had some kind of blood treatment for his ACL injury. Is this something that’s available for anyone or just celebrities with lots of money? If there’s something out there that could help my ACL (besides surgery), I’m all interested.

Anything that has to do with Tiger Woods is always hot news. So when he did receive a treatment of blood injection (his own blood) following anterior cruciate ligament (ACL) surgery, the media picked right up on it.

Platelet-rich plasma or PRP is the clear portion of blood (plasma) with the blood clotting platelets. It is taken from the patient so doesn’t require blood donors. The growth factors contained within the platelets enhance the body’s natural ability to heal itself. PRP is used to improve healing and shorten recovery time from acute and chronic soft tissue injuries.

It has been used for years after plastic surgery and surgery on the mouth, jaw, and neck. It seems to promote bone graft healing. Researchers have found a way to combine this substance with other chemicals to make it into a putty or gel that can be painted on a surgical site to speed up healing.

Blood injection therapy of this type has been used for knee osteoarthritis, degenerative cartilage, spinal fusion, bone fractures that don’t heal, and poor wound healing. This treatment technique is fairly new in the sports medicine treatment of musculoskeletal problems, but gaining popularity quickly.

Although very popular with some medical experts, the use of platelet-rich plasma is still considered highly controversial. There just isn’t enough scientific evidence yet to offer clear treatment guidelines for who, how, when, and why to use this treatment.
You may be a good candidate but your orthopedic surgeon would have to be the one to evaluate you and make that determination.

I’m feeling like an old grandmother today with bursitis in my knee and my elbow and I’m only 55-years-old. I always thought of this as an old-lady disease but here I am with it. Is it really a reflection of my age or something else?

Bursitis is not an age-dependent condition. This condition can affect people of all ages. Older adults are the most likely to develop pain, swelling, and tenderness around a joint from bursitis. But younger folks can be affected, too.

Causes of bursitis include trauma, inflammation, and infection. When trauma is the cause, it may be the result of a direct blow or a fall onto the knee, elbow, hip, or heel that damages the bursa. So you see how this can happen to anyone.

An injury can causes bleeding into the bursa sac because the blood vessels in the tissues that make up the bursa are damaged and torn. In the skin, this would simply form a bruise, but in a bursa blood may actually fill the bursa sac. This causes the bursa to swell up like a rubber balloon filled with water.

The blood in the bursa is thought to cause an inflammatory reaction. The walls of the bursa may thicken and remain thickened and tender even after the blood has been absorbed by the body. This thickening and swelling of the bursa is what we refer to as bursitis.

The bursae can become irritated and inflamed in other ways. For example, in the case of prepatellar (knee) bursitis, repeated injury can lead to irritation and thickening of the bursa over time. People who work on their knees, such as carpet layers and plumbers, can repeatedly injure the prepatellar bursa (pad in front of and behind the patellar tendon just below the knee cap). This repeated injury can lead to irritation and thickening of the bursa over time.

When infection is the cause of bursitis, it is usually from a staph or strep infection. The bacteria enter the body close to the affected joint through a cut or small opening in the skin. A minor skin infection of the skin over the bursa can spread down into the bursa. In this case, instead of blood or inflammatory fluid in the bursa, pus fills it. The area around the bursa becomes hot, red, and very tender.

Bacteria can travel to the joint via the bloodstream but it’s not thought that this is the way infectious bursitis develops. That’s because there isn’t much of a blood supply to the bursa.

Age-related changes in the soft tissues certainly can lead to bursitis. But bursitis can also be associated with some other systemic diseases such as sarcoidosis (and inflammatory condition) or gout. Usually, the physician who diagnoses the problem can see a pattern that might suggest the underlying cause. If you’re interested, ask your doctor what he or she thinks might be the cause of your bursitis.

I am supposed to fast for 12 hours before my scheduled surgery next week and I’m a little worried. I confess to being addicted to caffeine and I know I’ll get a lollapallooza of a headache if I don’t get my daily “fix.” How can I avoid this problem without my coffee, chocolate, and daily energy drink?

Don’t hesitate to ask your surgeon this question. It is a common problem. Almost all adults (up to 95 per cent) ingest some form of caffeine everyday. Many people have a total caffeine intake up to 400 mg/day (that’s considered a high level). That may not be surprising when you consider caffeine is a substance in a variety of beverages as well as some foods and medications.

Caffeine withdrawal can produce headache and fatigue for anyone who has a chronic caffeine addiction. Withdrawal headaches can last up to a week. You don’t have to cope with headache pain as well as the effects of surgery. Restoring caffeine just after surgery can be helpful in reducing or avoiding post-operative headaches.

There’s no need to go “cold turkey” so-to-speak unless facing a prolonged period of fasting for surgery or other medical testing. But you should know that caffeine is a psychoactive agent.

Psychoactive means it has a stimulating effect on the central nervous system. Given its effects on the nervous system, some even consider this substance a drug. It certainly has addictive qualities and causes withdrawal. Eliminating moderate-to-high levels of caffeine from your diet may be a good idea and beneficial to your overall health.

I have just been diagnosed with a special kind of arthritis called psoriatic arthritis. It progressed from some mild joint swelling to a full blown, severe case in a matter of days. My doctor is talking about which medication is best to treat this. What do your experts say?

Psoriasis is a disease that most people think of as primarily a skin disease because the condition causes a persistent rash in various areas of the body. Psoriatic arthritis is a type of joint disease that occurs in roughly seven percent of people who have psoriasis.

Psoriatic arthritis affects people of all ages, but most get it between the ages of 30 and 50. Usually a patient has psoriasis (the skin rash) for many years before the arthritis develops, and the arthritis comes on slowly. Patients with psoriatic arthritis must manage both the outbreaks of itchy, scaly skin and the pain and stiffness of arthritis.

One of the most commonly used medications for the treatment of psoriatic arthritis (PsA) is a disease-modifying antirheumatic drug (DMARD) called methotrexate. DMARDs like methotrexate not only control symptoms, they also slow the progression of disease. That’s what makes them “disease-modifying”.

Methotrexate may not be as effective with psoriatic arthritis as it is with rheumatoid arthritis without the psoriasis. Some patients don’t respond at all while others have an adverse reaction to the medication. And in some cases, it may be necessary to combine methotrexate with another drug (e.g., infliximab) to get the desired results (decreased joint pain, swelling, and stiffness).

Infliximab is a type of disease-modifying medication in a class called anti-tumor necrosis factor (TNF) agents. The anti-TNF agents are a special type of antibody referred to as human monoclonal antibodies. They specifically target (and inhibit) tumor necrosis factor.

Tumor necrosis factor (TNF) promotes the inflammatory response, which in turn causes many of the clinical problems associated with autoimmune disorders such as rheumatoid arthritis. Golimumab is another new TNF-inhibitor that has been approved by the FDA for use with patients who have active moderate-to-severe psoriatic arthritis (PsA).

Your doctor will help you figure out which treatment approach might work best for you. Sometimes it takes a while (through trial and error) to find the right medication or best combination of therapies to get the optimal results.

There are also alternative kinds of therapy as well that help manage the disease such as acupuncture, Reiki, Therapeutic Touch, BodyTalk, and even hypnosis. Some patients seem to get a better response by combining traditional treatment (medications) with these complementary approaches.

I’m not trying to be a difficult patient but every drug I’ve taken for my arthritis just doesn’t work. Either I get worse side effects than the arthritis symptoms or it simply doesn’t work. I have a special kind of arthritis called psoriatic arthritis. Is there anything new on the horizon for this problem?

Psoriatic arthritis is a type of joint disease that occurs in roughly less than 10 percent of people who have psoriasis. Usually a patient has psoriasis (the skin rash) for many years before the arthritis develops, and the arthritis comes on slowly. Patients with psoriatic arthritis must manage both the outbreaks of itchy, scaly skin and the pain and stiffness of arthritis.

One of the most commonly used medications for the treatment of psoriatic arthritis (PsA) are disease-modifying antirheumatic drugs (DMARDs). DMARDs not only control symptoms, they also slow the progression of disease. That’s what makes them “disease-modifying”.

The use of disease-modifying antirheumatic drugs (DMARDs) has changed the quality of life for many patients suffering from the effects of psoriatic arthritis. For those individuals who do not do well with these drugs, there aren’t very many other choices. But scientists point to a “therapeutic pipeline” of drugs that may be available in the near future.

Oral medications (pills taken by mouth) currently under investigation for the treatment of psoriatic arthritis include ustekinumab, apremilast, and tofacitinib. Each of these medications works in a slightly different way to regulate the immune system.

Ustekinumab (Stelara, Centocor) is a human monoclonal antibody. It is directed against two specific interleukins (interleukin 12 and 23). Interleukins are naturally occurring proteins that regulate the immune system and inflammatory disorders like rheumatoid arthritis. In Phase III trials for moderate-to-severe psoriasis, ustekinumab was safe and effective, especially for patients who failed to respond to other standard medications.

Apremilast works as an anti-inflammatory by suppressing more than one pro-inflammatory cells including, TNF-alpha, interleukins 6, 17 & 23, and interferon-gamma (among others). It is currently in Phase III clinical trials for the treatment of psoriasis, psoriatic arthritis, and other chronic inflammatory diseases. Early stage studies found this medication to be safe and well-tolerated with few side effects.

Tofacitinib inhibits Janus kinase, an enzyme that acts as a special signaling messenger in the immune system. Tofacitinib is currently in phase two trials with psoriasis and will be tested next with psoriatic arthritis. Tests are scheduled to run until January 2015. So it may be a while before we see this one on the market for psoriatic arthritis.

Doc says I have to give up coffee if I want to get rid of my migraines. Would a single cup of coffee in the morning still be a problem?

Eliminating coffee can be an effective way to reduce migraine headaches. Caffeine in its various forms is considered a psychoactive agent. Psychoactive means it has a stimulating effect on the central nervous system.

Many migraine sufferers are addicted to caffeine and don’t realize its role in causing headaches. But there have been enough studies showing the link between caffeine consumption and headaches to take this seriously. And it’s not just coffee that we are talking about.

Don’t forget caffeine in tea, soft drinks, energy drinks, and chocolate. There is caffeine in many over-the-counter drugs (for cold symptoms, headache pain relievers) and some prescription medications.

Taking caffeine in any form decreases our fatigue and boosts our energy level — that’s why so many people reach for that cup of coffee, latte, espresso, or chocolate bar. Chronic fatigue from too many late nights and lack of sleep makes an early morning jolt of java or energy bar necessary to jump start the day.

Your physician is right that cutting out caffeine is a must if you want to beat the migraines. But good nutrition and getting enough sleep are also important. If eliminating caffeine in all its forms does not stop the headaches, there may be other triggering factors to consider.

For example, certain foods (e.g., aged cheese and other dairy products, vinegar, lunch meats, alcohol, nuts, yeast products) are known to produce headaches in some people. Caffeine reduction is a good place to start. if that is not completely successful, your physician will help you find other triggers as well.

I’ve heard there’s a new drug out for lupus. What do you know about it? Should I jump on the wagon?

Lupus is a chronic inflammatory autoimmune disorder that can affect just the skin (face, neck, scalp) or target organs and any system in the body. Autoimmune means that the immune system mistakenly attacks body parts in an effort to get rid of them. Why a person’s immune system sees your own body as foreign or something to attack remains a mystery.

Symptoms vary depending on the body part, cells, or systems affected. There can be a skin rash, severe joint pain, extreme fatigue, inflammation of blood vessels, and hair loss. Headaches, irritability, and depression signal autoantibodies reacting with the nervous system.

Some patients report problems with shortness of breath, seizures, strokes, and/or difficulty with memory. Anemia, hepatitis, nausea, vomiting, diarrhea, and abdominal pain are among the many other symptoms possible.

The standard means of treatment has been with corticosteroids (antiinflammatory drugs) and medications that suppress the overactive immune system. Drugs to treat malaria have also been helpful. But now with the introduction ofBenlysta (belimumab), patients have a new treatment option.

The drug is administered intravenously (through a vein) once a month. It is designed to target B-lymphocyte stimulator protein. The goal is to reduce the number of abnormal B-cells. The effect is to turn down the immune system response.

Benlysta is the first drug to be developed specifically to treat lupus. It is considered safe, effective, and provides tolerable treatments. Not everyone can benefit from this drug and there are some potential side effects.

In drug trials before Benlysta was approved for public use, only one in three patients experienced relief from their symptoms. Because Benlysta weakens the immune system, patients taking the drug are at an increased risk for infections, cancers, depression, and suicide. The drug was not specifically studied in African-Americans, the group affected by lupus most often.

Lupus sufferers may find Benlysta helpful in reducing flare-ups, providing less fatigue, and resuming a more normal lifestyle. Patients who have had success using this drug for their lupus say their quality of life is much improved. With no cure for lupus and treatment only able to target the symptoms, Benlysta may give some patients a new lease on life.

If you are still interested, see your physician to find out if this drug may help you.

What is lupus and how is it treated? My sister-in-law who is hispanic was just diagnosed. They say it’s more common in this ethnic group. Other than that, we don’t know much about this problem.

Lupus is a chronic inflammatory autoimmune disorder. Autoimmune means that the immune system mistakenly attacks body parts in an effort to get rid of them. Why a person’s immune system sees your own body as foreign or something to attack remains a mystery.

In any case, the immune system can no longer tell the difference between healthy and harmful tissues in the body so it starts to attack healthy organs. Lupus is associated with inflammation, joint pain, and arthritis.

Lupus can affect just the skin (face, neck, scalp). This condition is called discoid lupus. Or it can target organs and any system in the body. This second form of lupus is called systemic lupus erythematosus or SLE.

According to the Lupus Foundation of America about 1.5 million Americans have some form of lupus. Systemic lupus erythematosus (SLE) rarely develops in older people. It is primarily a disease of young women in their childbearing years. Men and children can develop lupus but this happens much less often than in women.

Lupus (SLE) is three times more common in African American women than in Caucasian women and is also more common in women of Hispanic, Asian, and Native American descent. It is believed that both genetic and environmental factors play a role in the development of the disease.

Other risk factors include physical or mental stress, which can provoke neuroendocrine changes affecting immune cell function; streptococcal or viral infections; exposure to sunlight or ultraviolet light, which can cause inflammation and tissue damage; immunization; pregnancy; and abnormal estrogen metabolism.

There is currently no cure, only treatments to manage lupus. The standard treatment has been with corticosteroids (antiinflammatory drugs) and medications that suppress the overactive immune system.

Drugs to treat malaria have also been helpful. In March of 2011, the FDA approved a drug called Benlysta (belimumab), giving patients with lupus a new treatment option. This is the first drug to be specifically designed for lupus patients.

Benlysta may allow patients to reduce the amount of corticosteroids they are currently using to manage the inflammatory symptoms of lupus. And that’s important because these drugs can do more organ damage over the long term than the disease itself. In addition to reduced lupus symptoms, patients receiving this new drug reported fewer flare-ups, less fatigue, and better quality of life.

What’s the difference between vitamin D insufficiency and deficiency? I see both terms and wonder if I am one or the other.

Vitamin D helps regulate calcium in the body needed for good bone health. The body makes its own vitamin D through foods we eat and from sun exposure of the skin. Calcium is absorbed from the gastrointestinal tract but requires enough vitamin D to do so. The two chemicals are linked together very closely through hormone regulation.

The difference between insufficiency and deficiency is a matter of degree. Vitamin D insufficiency is defined as a blood level of 25-hydroxyvitamin-D (25 OHD) that falls below 32 ng/mL. 25 OHD is a chemical compound that must be present in the body in order for vitamin D to be made. It is called a precursor (comes before) chemical.

Vitamin D deficiency occurs when 25 OHD levels fall below 20 ng/mL. The levels for insufficiency and deficiency are actually determined by another factor — and that is the amount of 25 OHD needed to keep parathyroid levels in the normal range.

Without going into the complex physiology of the body to explain the interactions between the hormonal systems, suffice it to say that vitamin D levels and parathyroid function are intimately linked together.

A blood test is required to find out your own vitamin D status. Your physician, nurse practitioner, or physician’s assitant can order this test for you. The results will be used to guide you regarding any changes required in diet, sun exposure, or vitamin supplementation you may need.

My brother was just diagnosed with a form of arthritis called psoriatic arthritis. He’s not saying much. Could you tell us what’s the worse he might expect with this disease?

Arthritis comes in many forms including one called psoriatic arthritis (PsA). Psoriasis is a disease that most people think of as primarily a skin disease because the condition causes a persistent rash in various areas of the body. Psoriatic arthritis is a type of joint disease that occurs in roughly seven percent of people who have psoriasis.

Psoriatic arthritis affects people of all ages, but most get it between the ages of 30 and 50. Usually a patient has psoriasis (the skin rash) for many years before the arthritis develops, and the arthritis comes on slowly. But this is not always the case. No matter what, patients with psoriatic arthritis must manage both the outbreaks of itchy, scaly skin and the pain and stiffness of arthritis.

Psoriatic arthritis (PsA) can be a very aggressive disease. It can affect the small joints of the hands and feet causing considerable damage and disability. People who have psoriatic arthritis also tend to develop other chronic problems such as diabetes, metabolic syndrome, and heart disease.

Tissue inflammation affecting the skin, joints, nails, and tendons can really put a damper on activities, mood, and perceived quality of life. You may see evidence of decline in your brother over time.

Family support is very important for patients with this condition. Some patients don’t like to go to the doctor and start to miss appointments or extend the time between appointments more than they should. This is a mistake since keeping up on controlling the disease with medication is vital. Your encouragement and care in your brother’s life will be needed in this phase of his life.

I am seeing a new rheumatologist for my psoriatic arthritis. She seems bent on having every imaging study done possible — X-rays, MRIs, ultrasound. My old rheumatologist didn’t do all this business. Do I really need all these studies?

Psoriatic arthritis (PsA) can be a very aggressive disease. Based on the evidence we have so far, it is believed that early recognition and treatment of this problem yields better results.

There is often a wide range of signs and symptoms involving many different body parts. Physicians must use several diagnostic tools such as X-rays, ultrasonography, and MRIs to catch them all.

Each one of these tests provides a little different information. For example, X-rays show early signs of bone erosion but do not reveal anything about the condition of tendons, ligaments, or other soft tissues often affected by psoriatic arthritis.

Ultrasonography, the use of sound waves to create a picture of what’s going on inside, provides a better look at the whole package: bones, joints, and soft tissues. This diagnostic test is also noninvasive and does not expose you to any radiation. Ultrasound also has the ability to show small changes in the nails and early signs of inflammation in tendons and small joints.

MRIs can show bone marrow edema, tenosynovitis, and early joint erosion. Tenosynovitis is the inflammation of the fluid-filled sheath (called the synovium) that surrounds a tendon. Changes in the small joints of the hands and feet don’t show up well on MRIs like they do with ultrasonography.

One advantage MRIs do have over ultrasonography is the availability of whole body MRI. By scanning the entire body, it is possible to identify areas of inflammation undetected by clinical exam. And whole-body ultrasonography just isn’t reasonable.

Knowing that the correct management of this condition depends on early detection of bone, joint, and soft tissue pathology helps us understand the need for improved diagnostic and treatment approaches.

The potential for severe progression of disease may be halted (or at least slowed) with a management approach that includes (repeated or serial) diagnostic imaging throughout the course of treatment.

It sounds like your rheumatologist is right on target with the evidence we have today about the best way to care for patients with psoriatic arthritis.

Do you think it makes a difference whether a surgeon uses imaging to inject the shoulder joint? My surgeon takes X-rays before but does the actual injection in the office just using visual guidance. From what I’ve found on the Internet, this method isn’t as accurate as with using ultrasound or real-time X-rays.

According to the results of a recent systematic review, studies show that accuracy of joint injections can be improved. In the shoulder, coming in from behind (posterior approach) is more accurate than from the front (anterior approach).

Additionally, the surgeon who uses ultrasound, fluoroscopy (real-time X-ray), or magnetic resonance imaging to guide the needle to the right spot will also be more accurate. And that was true for all joints (elbow, knee, or shoulder).

X-rays taken before the procedure help the surgeon see if there are any anatomic changes, deformities, or problems like arthritis before making the actual injection. Real-time imaging during the actual procedure assists the surgeon in making sure the needle goes into the joint space.

Taking a look at the larger (combined) sample created by the review, here’s what they found for accuracy. With and without imaging to guide the surgeon showed differences of 79 per cent (without imaging) and 95 per cent (with imaging) for the shoulder. For the knee, accuracy improved from 79 per cent to 99 per cent.

But does improved accuracy mean better results? Accuracy and benefit in terms of patient outcomes are two separate things. People who receive joint injections often improve regardless of the accuracy of the needle placement. The placebo effect (patient expects to get better and does) may have as much of a role in results as accurate placement.

I’m a parent who has had to practice “tough love” many times with my son who is now a young adult. His latest escapade involves shooting up drugs and landing in the hospital with something called compartment syndrome of the forearm. I don’t plan to rescue him, but I’d like to know what could happen as a result of this injury.

Compartment syndrome can occur as a result of an injury such as a bone fracture, snakebite, surgery, or stab wound that causes swelling inside the entire forearm. Other reported causes of forearm compartment syndrome include gunshot wounds, hemophilia (blood clotting disorder), phlebitis (inflammation of the veins), use of a tourniquet, and drug abuse. In the case of shooting up drugs, the use of a tourniquet to help the drug user find a vein can trigger a compartment syndrome.

With any compartment syndrome, fluid from swelling is trapped inside the osteofascial envelope. This envelope is a layer of connective tissue around the muscles, tendons, blood vessels, and nerves.

The pressure placed on these sensitive soft tissues can cause death of the tissues. This condition is usually considered an emergency requiring immediate surgery to release the skin and soft tissues and let the fluid drain out. That procedure is called a fasciotomy.

Early diagnosis is important to prevent serious complications. Patients must be observed carefully for any signs of contracture (muscles tighten so much that joints can’t move), gangrene, deformity, and complex regional pain syndrome (CRPS).

With death of tissue (called necrosis, the surgeon performs a procedure called debridement. The dead tissue is removed and the area is cleaned out with a saline solution. If enough tissue has to be cut out, the patient may need a skin graft to close the wound.

We are not painting a very optimistic picture here. This condition has the potential to be very serious. If the problem is diagnosed early enough and pressures can be relieved, the patient can have a successful outcome. Sometimes it’s even possible to treat it without surgery. We hope that’s the case for your son.

Our family watched the new release of an old western (“True Grit”) last night. The girl in the movie gets a snake bite and ends up losing her arm. The cowboy who rescues her does cut the snake bite open and suck the poison out. So why did she still end up losing her arm? I really didn’t know how to explain it to the kids.

Untreated, poinsonous snake bites can kill people but this doesn’t happen as often as most people think. Movies, of course, dramatize events like snake bites. The updated version of True Grit did an excellent job of portraying the need for emergency treatment.

After administering first aid to the girl, the main character (Rooster Cogburn played by Jeff Bridges) rides with the girl until the horse gives out. Then he carries her through the night the rest of the way. In the end, her life is saved but her arm has to be amputated.

In a real situation of untreated snake pit (or delayed treatment), the arm can develop a condition called compartment syndrome. The inflammatory response to the poison causes excess fluid and swelling.

This fluid from the swelling gets trapped inside the osteofascial envelope. This envelope is a layer of connective tissue around the muscles, tendons, blood vessels, and nerves.

The pressure placed on these sensitive soft tissues can cause death of the tissues. This condition is usually considered an emergency requiring immediate surgery to release the skin and soft tissues and let the fluid drain out. Today that procedure is called a fasciotomy.

The events of the movie inferred that by the time the girl received medical care, necrosis and gangrene had set in. The only way to save her life was to remove the arm. Today, modern treatment with early surgical intervention and antibiotics has reduced the incidence of compartment syndrome considerably. Complications can still occur but amputation is not the usual final outcome.
