Emphysema Awareness

Leave a reply

Chronic obstructive pulmonary disease (COPD) is one of the leading cause of death in the U.S. and affects more than 12 million Americans.  COPD – which includes emphysema and chronic bronchitis – is a term used to describe the obstruction of airflow.

COPD cannot be cured, but it can be treated. Early detection and diagnosis is the key to successful management of this chronic disease.

Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli (air sacs in the lung). In people with emphysema, the lung tissue involved in exchange of gases (oxygen and carbon dioxide) is impaired or destroyed. Emphysema is included in a group of diseases called chronic obstructive pulmonary disease or COPD (pulmonary refers to the lungs). Emphysema is called an obstructive lung disease because airflow on exhalation is slowed or stopped because over-inflated alveoli do not exchange gases when a person breaths due to little or no movement of gases out of the alveoli.

Emphysema changes the anatomy of the lung in several important ways. This is due to in part to the destruction of lung tissue around smaller airways. This tissue normally holds these small airways, called bronchioles, open, allowing air to leave the lungs on exhalation. When this tissue is damaged, these airways collapse, making it difficult for the lungs to empty and the air (gases) becomes trapped in the alveoli.

Normal lung tissue looks like a new sponge. Emphysematous lung looks like an old used sponge, with large holes and a dramatic loss of “springy-ness” or elasticity. When the lung is stretched during inflation (inhalation), the nature of the stretched tissue wants to relax to its resting state. In emphysema, this elastic function is impaired, resulting in air trapping in the lungs. Emphysema destroys this spongy tissue of the lung and also severely affects the small blood vessels (capillaries of the lung) and airways that run throughout the lung. Thus, not only is airflow affected but so is blood flow. This has dramatic impact on the ability for the lung not only to empty its air sacs called alveoli (pleural for alveolus) but also for blood to flow through the lungs to receive oxygen.

Marfan Syndrome Awareness

Marfan syndrome is a genetic disorder that affects the body’s connective tissue. Connective tissue holds all the body’s cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly.

Connective tissue is made up of proteins. The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1. This mutation results in an increase in a protein called transforming growth factor beta, or TGF-β. The increase in TGF-β causes problems in connective tissues throughout the body, which in turn creates the features and medical problems associated with Marfan syndrome and some related disorders.

Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, as well. Features of the disorder are most often found in the heart, blood vessels, bones, joints, and eyes. Some Marfan features – for example, aortic enlargement (expansion of the main blood vessel that carries blood away from the heart to the rest of the body) – can be life-threatening. The lungs, skin and nervous system may also be affected. Marfan syndrome does not affect intelligence.

Who has Marfan syndrome?
About 1 in 5,000 people have Marfan syndrome, including men and women of all races and ethnic groups. About 3 out of 4 people with Marfan syndrome inherit it, meaning they get the genetic mutation from a parent who has it. But some people with Marfan syndrome are the first in their family to have it; when this happens it is called a spontaneous mutation. There is a 50 percent chance that a person with Marfan syndrome will pass along the genetic mutation each time they have a child.

Knowing the signs of Marfan syndrome can save lives
People with Marfan syndrome are born with it, but features of the disorder are not always present right away. Some people have a lot of Marfan features at birth or as young children – including serious conditions like aortic enlargement. Others have fewer features when they are young and don’t develop aortic enlargement or other signs of Marfan syndrome until they are adults. Some features of Marfan syndrome, like those affecting the heart and blood vessels, bones or joints, can get worse over time.

This makes it very important for people with Marfan syndrome and related disorders to receive accurate, early diagnosis and treatment. Without it, they can be at risk for potentially life-threatening complications. The earlier some treatments are started, the better the outcomes are likely to be.

Knowing the signs of Marfan syndrome can save lives. Our community of experts estimates that nearly half the people who have Marfan syndrome don’t know it. This is something we are working hard to change.

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.

April Is National Sarcoidosis Awareness Month

Sarcoidosis is an inflammatory disease that can affect almost any organ in the body. It causes heightened immunity, which means that a person’s immune system, which normally protects the body from infection and disease, overreacts, resulting in damage to the body’s own tissues. The classic feature of sarcoidosis is the formation of granulomas, microscopic clumps of inflammatory cells that group together (and look like granules, hence the name). When too many of these clumps form in an organ they can interfere with how that organ functions.

Sarcoidosis is a multi-system disorder.  Symptoms typically depend on which organ the disease affects.  Most often the disease will affect the lungs.

  • General: About one third of patients will experience non-specific symptoms of fever, fatigue, weight loss, night sweats and an overall feeling of malaise (or ill health).
  • Lungs: The lungs are affected in more than 90% of patients with sarcoidosis.  A cough that does not go away, shortness of breath, particularly with exertion and chest pain occur most frequently with the pulmonary form of the disease.
  • Lymph Nodes: Up to 90% of sarcoidosis patients have enlarged lymph nodes. Most often they are in the neck, but those under the chin, in the armpits and in the groin can be affected.  The spleen, which is part of the lymphatic system, can also be affected.
  • Liver: Although between 50% to 80% of patients with sarcoidosis will have granulomas in their liver, most are without symptoms and do not require treatment.
  • Heart: Researchers estimate that cardiac sarcoidosis, affects more than 10 percent of people with sarcoidosis in the United States, and perhaps as mHeart: any as 25 percent.  Sarcoidosis can cause the heart to beat weakly resulting in shortness of breath and swelling in the legs.  It can also cause palpitations (irregular heartbeat).
  • Brain & Nervous System: From 5% to 13% of patients have neurologic disease.  Symptoms can include headaches, visual problems, weakness or numbness of an arm or leg and facial palsy.
  • Skin:  One in four (25%) of patients will have skin involvement.  Painful or red, raised bumps on the legs or arms (called erythema nodosum), discoloration of the nose, cheeks, lips and ears (called lupus pernio) or small brownish and painless skin patches are symptoms of the cutaneous form of the disease.
  • Bones, Joints & Muscles:  Joint pain occurs in about one-third of patients.  Other symptoms include a mass in the muscle, muscle weakness and arthritis in the joints of the ankles, knees, elbows, wrists, hands and feet.
  • Eyes:  Any part of the eye can be affected by sarcoidosis and about 25% of patients have ocular involvement.  Common symptoms include: burning, itching, tearing, pain, red eye, sensitivity to light (photophobia), dryness, seeing black spots (called floaters) and blurred vision.  Chronic uveitis (inflammation of the membranes or uvea of the eye) can lead to glaucoma, cataracts and blindness.
  • Sinuses, Nasal Muscosa (lining) & Larynx:  About 5% of patients will have involvement in the sinuses with symptoms that can include sinusitis, hoarseness or shortness of breath.
  • Other Organs:  Rarely, the gastrointestinal tract, reproductive organs, salivary glands and the kidneys are affected.
