Myasthenia Gravis Awareness

Myasthenia Gravis (pronounced My-as-theen-ee-a Grav-us) comes from the Greek and Latin words meaning “grave muscular weakness.” The most common form of MG is a chronic autoimmune neuromuscular disorder that is characterized by fluctuating weakness of the voluntary muscle groups. The prevalence of MG in the United States is estimated to be about 20/100,000 population. However, MG is probably under diagnosed and the prevalence may be higher. Myasthenia Gravis occurs in all races, both genders, and at any age. MG is not thought to be directly inherited nor is it contagious. It does occasionally occur in more than one member of the same family.

The voluntary muscles of the entire body are controlled by nerve impulses that arise in the brain. These nerve impulses travel down the nerves to the place where the nerves meet the muscle fibers. Nerve fibers do not actually connect with muscle fibers. There is a space between the nerve ending and muscle fiber; this space is called the neuromuscular junction.

When the nerve impulse originating in the brain arrives at the nerve ending, it releases a chemical called acetylcholine. Acetylcholine travels across the space to the muscle fiber side of the neuromuscular junction where it attaches to many receptor sites. The muscle contracts when enough of the receptor sites have been activated by the acetylcholine. In MG, there can be as much as an 80% reduction in the number of these receptor sites. The reduction in the number of receptor sites is caused by an antibody that destroys or blocks the receptor site.

Antibodies are proteins that play an important role in the immune system. They are normally directed at foreign proteins called antigens that attack the body. Such foreign proteins include bacteria and viruses. Antibodies help the body to protect itself from these foreign proteins. For reasons not well understood, the immune system of the person with MG makes antibodies against the receptor sites of the neuromuscular junction. Abnormal antibodies can be measured in the blood of many people with MG. The antibodies destroy the receptor sites more rapidly than the body can replace them. Muscle weakness occurs when acetylcholine cannot activate enough receptor sites at the neuromuscular junction.

Aphasia Awareness

Aphasia is a disorder stemming from damage to the language portion of the brain, usually the left side. Aphasia is a communication disorder that interferes with the ability to process, understand or speak language. There are varying degrees of Aphasia from mild to severe. Aphasia can also cause a difficulty in reading or writing. Aphasia can occur from strokes, head injuries and from brain tumors. It is more common in adults but can also affect children.

Some people with aphasia may understand communication from others while not being able to speak themselves. Others with aphasia may not be able to speak or listen to others effectively. Aphasia usually does not affect thinking skills, only those parts of the brain required for communication.

Post-Traumatic Stress Disorder Awareness

In order to bring greater awareness to the issue of Post-Traumatic Stress Disorder (PTSD), the United States Senate designated June 27th as National PTSD Awareness Day. In addition, June has been designated as PTSD Awareness Month by the National Center for PTSD (NCPTSD).

PTSD is an anxiety disorder resulting from exposure to a single traumatic event or multiple traumatic events, such as sexual or physical assault, natural or man-made disaster, and war-related combat stress. Symptoms of PTSD include persistent intrusive thoughts and distressing dreams about the traumatic event, triggered emotional responses to reminders of the trauma, efforts to avoid thinking or talking about the trauma, and persistent hyper-vigilance for cues that indicate additional danger or trauma re-occurring.

An estimated 70 percent of adults in the United States have experienced a traumatic event at least once in their lives and up to 20 percent of these people go on to develop posttraumatic stress disorder, or PTSD.
An estimated 5 percent of Americans—more than 13 million people—have PTSD at any given time.
Approximately 8 percent of all adults—1 of 13 people in this country—will develop PTSD during their lifetime.
An estimated 1 out of 10 women will get PTSD at some time in their lives. Women are about twice as likely as men to develop PTSD.

Arthritis Awareness

Arthritis is very common but is not well understood. Actually, “arthritis” is not a single disease; it is an informal way of referring to joint pain or joint disease. There are more than 100 different types of arthritis and related conditions. People of all ages, sexes and races can and do have arthritis, and it is the leading cause of disability in America. Nearly 53 million adults and 300,000 children have some type of arthritis. It is most common among women and occurs more frequently as people get older.

Common arthritis joint symptoms include swelling, pain, stiffness and decreased range of motion. Symptoms may come and go. They can be mild, moderate or severe. They may stay about the same for years, but may progress or get worse over time. Severe arthritis can result in chronic pain, inability to do daily activities and make it difficult to walk or climb stairs. Arthritis can cause permanent joint changes. These changes may be visible, such as knobby finger joints, but often the damage can only be seen on X-ray. Some types of arthritis also affect the heart, eyes, lungs, kidneys and skin as well as the joints.

There are different types of arthritis:

Degenerative Arthritis
Osteoarthritis is the most common type of arthritis. When the cartilage – the slick, cushioning surface on the ends of bones – wears away, bone rubs against bone, causing pain, swelling and stiffness. Over time, joints can lose strength and pain may become chronic. Risk factors include excess weight, family history, age and previous injury (an anterior cruciate ligament, or ACL, tear, for example).

When the joint symptoms of osteoarthritis are mild or moderate, they can be managed by:

balancing activity with rest
using hot and cold therapies
regular physical activity
maintaining a healthy weight
strengthening the muscles around the joint for added support
using assistive devices
taking over-the-counter (OTC) pain relievers or anti-inflammatory medicines
avoiding excessive repetitive movements

If joint symptoms are severe, causing limited mobility and affecting quality of life, some of the above management strategies may be helpful, but joint replacement may be necessary.

Osteoarthritis can prevented by staying active, maintaining a healthy weight, and avoiding injury and repetitive movements.

Inflammatory Arthritis
A healthy immune system is protective. It generates internal inflammation to get rid of infection and prevent disease. But the immune system can go awry, mistakenly attacking the joints with uncontrolled inflammation, potentially causing joint erosion and may damage internal organs, eyes and other parts of the body. Rheumatoid arthritis and psoriatic arthritis are examples of inflammatory arthritis. Researchers believe that a combination of genetics and environmental factors can trigger autoimmunity. Smoking is an example of an environmental risk factor that can trigger rheumatoid arthritis in people with certain genes.

With autoimmune and inflammatory types of arthritis, early diagnosis and aggressive treatment is critical. Slowing disease activity can help minimize or even prevent permanent joint damage. Remission is the goal and may be achieved through the use of one or more medications known as disease-modifying antirheumatic drugs (DMARDs). The goal of treatment is to reduce pain, improve function, and prevent further joint damage.

Infectious Arthritis
A bacterium, virus or fungus can enter the joint and trigger inflammation. Examples of organisms that can infect joints are salmonella and shigella (food poisoning or contamination), chlamydia and gonorrhea (sexually transmitted diseases) and hepatitis C (a blood-to-blood infection, often through shared needles or transfusions). In many cases, timely treatment with antibiotics may clear the joint infection, but sometimes the arthritis becomes chronic.

Metabolic Arthritis
Uric acid is formed as the body breaks down purines, a substance found in human cells and in many foods. Some people have high levels of uric acid because they naturally produce more than is needed or the body can’t get rid of the uric acid quickly enough. In some people the uric acid builds up and forms needle-like crystals in the joint, resulting in sudden spikes of extreme joint pain, or a gout attack. Gout can come and go in episodes or, if uric acid levels aren’t reduced, it can become chronic, causing ongoing pain and disability.

Diagnosing Arthritis
Arthritis diagnosis often begins with a primary care physician, who performs a physical exam and may do blood tests and imaging scans to help determine the type of arthritis. An arthritis specialist, or rheumatologist, should be involved if the diagnosis is uncertain or if the arthritis may be inflammatory. Rheumatologists typically manage ongoing treatment for inflammatory arthritis, gout and other complicated cases. Orthopaedic surgeons do joint surgery, including joint replacements. When the arthritis affects other body systems or parts, other specialists, such as ophthalmologists, dermatologists or dentists, may also be included in the health care team.
