What causes Atherosclerosis ? 
 The exact cause of atherosclerosis isn't known. However, studies show that atherosclerosis is a slow, complex disease that may start in childhood. It develops faster as you age.
                
Atherosclerosis may start when certain factors damage the inner layers of the arteries. These factors include:
                
Smoking
                
High amounts of certain fats and cholesterol in the blood
                
High blood pressure
                
High amounts of sugar in the blood due to insulin resistance or diabetes
                
Plaque may begin to build up where the arteries are damaged. Over time, plaque hardens and narrows the arteries. Eventually, an area of plaque can rupture (break open).
                
When this happens, blood cell fragments called platelets (PLATE-lets) stick to the site of the injury. They may clump together to form blood clots. Clots narrow the arteries even more, limiting the flow of oxygen-rich blood to your body.
                
Depending on which arteries are affected, blood clots can worsen angina (chest pain) or cause a heart attack or stroke.
                
Researchers continue to look for the causes of atherosclerosis. They hope to find answers to questions such as:
                
Why and how do the arteries become damaged?
                
How does plaque develop and change over time?
                
Why does plaque rupture and lead to blood clots?
What are the symptoms of Atherosclerosis ? 
 Atherosclerosis usually doesn't cause signs and symptoms until it severely narrows or totally blocks an artery. Many people don't know they have the disease until they have a medical emergency, such as a heart attack or stroke.
                
Some people may have signs and symptoms of the disease. Signs and symptoms will depend on which arteries are affected.
                
Coronary Arteries
                
The coronary arteries supply oxygen-rich blood to your heart. If plaque narrows or blocks these arteries (a disease called coronary heart disease, or CHD), a common symptom is angina. Angina is chest pain or discomfort that occurs when your heart muscle doesn't get enough oxygen-rich blood.
                
Angina may feel like pressure or squeezing in your chest. You also may feel it in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion. The pain tends to get worse with activity and go away with rest. Emotional stress also can trigger the pain.
                
Other symptoms of CHD are shortness of breath and arrhythmias (ah-RITH-me-ahs). Arrhythmias are problems with the rate or rhythm of the heartbeat.
                
Plaque also can form in the heart's smallest arteries. This disease is called coronary microvascular disease (MVD). Symptoms of coronary MVD include angina, shortness of breath, sleep problems, fatigue (tiredness), and lack of energy.
                
Carotid Arteries
                
The carotid arteries supply oxygen-rich blood to your brain. If plaque narrows or blocks these arteries (a disease called carotid artery disease), you may have symptoms of a stroke. These symptoms may include:
                
Sudden weakness
                
Paralysis (an inability to move) or numbness of the face, arms, or legs, especially on one side of the body
                
Confusion
                
Trouble speaking or understanding speech
                
Trouble seeing in one or both eyes
                
Problems breathing
                
Dizziness, trouble walking, loss of balance or coordination, and unexplained falls
                
Loss of consciousness
                
Sudden and severe headache
                
Peripheral Arteries
                
Plaque also can build up in the major arteries that supply oxygen-rich blood to the legs, arms, and pelvis (a disease calledperipheral artery disease).
                
If these major arteries are narrowed or blocked, you may have numbness, pain, and, sometimes, dangerous infections.
                
Renal Arteries
                
The renal arteries supply oxygen-rich blood to your kidneys. If plaque builds up in these arteries, you may develop chronic kidney disease. Over time, chronic kidney disease causes a slow loss of kidney function.
                
Early kidney disease often has no signs or symptoms. As the disease gets worse it can cause tiredness, changes in how you urinate (more often or less often), loss of appetite, nausea (feeling sick to the stomach), swelling in the hands or feet, itchiness or numbness, and trouble concentrating.
How to prevent Atherosclerosis ? 
 Taking action to control your risk factors can help prevent or delay atherosclerosis and its related diseases. Your risk for atherosclerosis increases with the number of risk factors youhave.
                
One step you can take is to adopt a healthy lifestyle, which can include:
                
Heart-Healthy Eating. Adopt heart-healthy eating habits, which include eating different fruits and vegetables (including beans and peas), whole grains, lean meats, poultry without skin, seafood, and fat-free or low-fat milk and dairy products. A heart-healthy diet is low in sodium, added sugar, solid fats, and refined grains. Following a heart-healthy diet is an important part of a healthy lifestyle.
                
Physical Activity. Be as physically active as you can. Physical activity can improve your fitness level and your health. Ask your doctor what types and amounts of activity are safe for you. Read more about Physical Activity and Your Heart.
                
Quit Smoking. If you smoke, quit. Smoking can damage and tighten blood vessels and raise your risk for atherosclerosis. Talk with your doctor about programs and products that can help you quit. Also, try to avoid secondhand smoke. Read more about Smoking and Your Heart.
                
Weight Control. If youre overweight or obese, work with your doctor to create a reasonable weight-loss plan. Controlling your weight helps you control risk factors foratherosclerosis.
                
Other steps that can prevent or delay atherosclerosis include knowing your family history of atherosclerosis. If you or someone in your family has an atherosclerosis-related disease, be sure to tell your doctor.
                
If lifestyle changes arent enough, your doctor may prescribe medicines to control your atherosclerosis risk factors. Take all of your medicines as your doctor advises.
What causes Primary Ciliary Dyskinesia ? 
 Primary ciliary dyskinesia (PCD) is a rare, inherited disease. "Inherited" means the disease is passed from parents to children through genes. With PCD, this process is very complex. Researchers are still learning how the disease is inherited and which genes are involved.
                
Generally, a child must inherit faulty genes from both parents to have PCD. These genes affect how cilia grow and function. Cilia are tiny, hair-like structures that line the airways.
                
The airways include your nose and linked air passages; mouth; larynx (LAR-ingks), or voice box; trachea (TRA-ke-ah), or windpipe; and tubes called bronchial tubes or bronchi, and their branches.
                
Cilia move mucus (a slimy substance) through your airways and toward your mouth to be coughed or sneezed out of your body. The mucus contains inhaled dust, bacteria, and other small particles.
                
Faulty genes may cause the cilia to be the wrong size or shape or move in the wrong way. Sometimes the cilia are missing altogether. If the cilia don't work well, bacteria stay in your airways. This can cause breathing problems, infections, and other disorders.
                
Primary Ciliary Dyskinesia
                

                
No single faulty gene causes all cases of PCD. Rather, many genes are associated with the disease.
                
If a child inherits a faulty gene (or genes) from only one parent, he or she may be a "PCD carrier." Carriers usually have no symptoms of PCD. However, carriers can pass faulty PCD genes on to their children.
Who is at risk for Primary Ciliary Dyskinesia? ? 
 Primary ciliary dyskinesia (PCD) is a rare disease that affects both males and females. The disease also affects people from all racial and ethnic groups.
                
Some people who have PCD have breathing problems from the moment of birth. However, other people can go through all or most of their lives without knowing that they have the disease.
What is (are) Kawasaki Disease ? 
 Kawasaki (KAH-wah-SAH-ke) disease is a rare childhood disease. It's a form of a condition calledvasculitis(vas-kyu-LI-tis). This condition involves inflammation of the blood vessels.
                
In Kawasaki disease, the walls of the blood vessels throughout the body become inflamed. The disease can affect any type of blood vessel in the body, including the arteries, veins, and capillaries.
                
Sometimes Kawasaki disease affects the coronary arteries, which carry oxygen-rich blood to the heart. As a result, some children who have Kawasaki disease may develop serious heart problems.
                
Overview
                
The cause of Kawasaki disease isn't known. The body's response to a virus or infection combined with genetic factors may cause the disease. However, no specific virus or infection has been found, and the role of genetics isn't known.
                
The disease can't be passed from one child to another. Your child won't get it from close contact with a child who has the disease. Also, if your child has the disease, he or she can't pass it to another child.
                
Kawasaki disease affects children of all races and ages and both genders. It occurs most often in children of Asian and Pacific Island descent. The disease is more likely to affect boys than girls. Most cases occur in children younger than 5years old.
                
One of the main symptoms of Kawasaki disease is a fever that lasts longer than5days. The fever remains high even after treatment with standard childhood fever medicines.
                
Children who have the disease also may have red eyes, red lips, and redness on the palms of their hands and soles of their feet. These are all signs of inflamed blood vessels.
                
Early treatment helps reduce the risk of Kawasaki disease affecting the coronary arteries and causing serious problems.
                
Outlook
                
Kawasaki disease can't be prevented. However, most children who have the disease usually recover within weeks of getting symptoms. Further problems are rare.
                
The disease affects some children's coronary arteries, which can cause serious problems. These children need long-term care and treatment.
                
Researchers continue to look for the cause of Kawasaki disease and better ways to diagnose and treat it. They also hope to learn more about long-term health risks, if any, for people who have had the disease.

The disease is more likely to affect boys than girls. Most cases occur in children younger than 5 years old. Kawasaki disease is rare in children older than 8.
What are the symptoms of Kawasaki Disease ? 
 Major Signs and Symptoms
                
One of the main symptoms during the early part of Kawasaki disease, called the acute phase, is fever. The fever lasts longer than 5 days. It remains high even after treatment with standard childhood fever medicines.
                
Other classic signs of the disease are:
                
Swollen lymph nodes in the neck
                
A rash on the mid-section of the body and in the genital area
                
Red, dry, cracked lips and a red, swollen tongue
                
Red, swollen palms of the hands and soles of the feet
                
Redness of the eyes
                
Other Signs and Symptoms
                
During the acute phase, your child also may be irritable and have a sore throat, joint pain, diarrhea, vomiting, and stomach pain.
                
Within 2 to 3 weeks of the start of symptoms, the skin on your child's fingers and toes may peel, sometimes in large sheets.
How to diagnose Kawasaki Disease ? 
 Kawasaki disease is diagnosed based on your child's signs and symptoms and the results from tests and procedures.
                
Specialists Involved
                
Pediatricians often are the first to suspect a child has Kawasaki disease. Pediatricians are doctors who specialize in treating children.
                
If the disease has affected your child's coronary (heart) arteries, a pediatric cardiologist will confirm the diagnosis and give ongoing treatment. Pediatric cardiologists treat children who have heart problems.
                
Other specialists also may be involved in treating children who have Kawasaki disease.
                
Signs and Symptoms
                
The doctor will check your child for the classic signs and symptoms of Kawasaki disease.
                
The doctor will rule out other diseases that cause similar symptoms. These diseases include Rocky Mountain spotted fever, scarlet fever, and juvenile rheumatoid arthritis.
                
Generally, your child will be diagnosed with Kawasaki disease if he or she has a fever that lasts longer than 5 days plus four other classic signs or symptoms of the disease.
                
However, not all children have classic signs and symptoms of Kawasaki disease. Tests and procedures can help confirm whether a child has the disease.
                
Tests and Procedures
                
Echocardiography
                
If the doctor thinks that your child has Kawasaki disease, he or she will likely recommendechocardiography(EK-o-kar-de-OG-ra-fee), or echo. This painless test uses sound waves to create pictures of the heart and coronary arteries.
                
Echo also can help show the disease's effects over time, if any, on your child's coronary arteries. Often, the disease's effects on the coronary arteries don't show up until the second or third week after the first symptoms appear. Thus, this test is done regularly after the diagnosis.
                
Some children who have Kawasaki disease don't have the classic signs and symptoms of the acute phase. Doctors may not diagnose these children until 2 to 3 weeks after the onset of the disease. This is when another common sign of Kawasaki disease occurspeeling of the skin on the fingers and toes.
                
If your child is diagnosed at this point, he or she will likely need echo right away to see whether the disease has affected the coronary arteries.
                
Other Diagnostic Tests
                
Doctors also use other tests to help diagnose Kawasaki disease, such as:
                
Blood tests. The results from blood tests can show whether the body's blood vessels are inflamed.
                
Chest x ray. This painless test creates pictures of structures inside the chest, such as the heart and lungs. A chest x ray can show whether Kawasaki disease has affected the heart.
                
EKG (electrocardiogram). This simple test detects and records the heart's electrical activity. An EKG can show whether Kawasaki disease has affected the heart.
How to prevent Kawasaki Disease ? 
 Kawasaki disease can't be prevented. However, most children who have the disease recoverusually within weeks of getting signs and symptoms. Further problems are rare.
What causes Hypersensitivity Pneumonitis ? 
 Repeatedly breathing in foreign substances can cause hypersensitivity pneumonitis (HP). Examples of these substances include molds, dusts, and chemicals. (Mold often is the cause of HP.) These substances also are known as antigens.
                
Over time, your lungs can become sensitive to antigens. If this happens, your lungs will become inflamed, which can lead to symptoms and may even cause long-term lung damage.
                
Antigens may be found in the home, workplace, or in other settings. Antigens can come from many sources, such as:
                
Bird droppings
                
Humidifiers, heating systems, and hot tubs
                
Liquid chemicals used in the landscaping and florist industries
                
Moldy hay, straw, and grain
                
Chemicals released during the production of plastics and electronics, and chemicals released during painting
                
Mold released during lumber milling, construction, and wood stripping
Who is at risk for Hypersensitivity Pneumonitis? ? 
 People who repeatedly breathe in foreign substances are at risk for hypersensitivity pneumonitis (HP). These substances, which also are known as antigens, include molds, dusts, and chemicals. However, most people who breathe in these substances don't develop HP.
                
People at increased risk include:
                
Farm and dairy cattle workers
                
People who use hot tubs often
                
People who are exposed to molds or dusts from humidifiers, heating systems, or wet carpeting
                
Bird fanciers (people who keep pet birds) and poultry handlers
                
Florists and landscapers, especially those who use liquid chemicals on lawns and gardens
                
People who work in grain and flour processing and loading
                
Lumber milling, construction, wood stripping, and paper and wallboard workers
                
People who make plastics or electronics, and those who paint or work with other chemicals
What are the symptoms of Hypersensitivity Pneumonitis ? 
 Signs and symptoms of hypersensitivity pneumonitis (HP) depend on whether the disease is acute (short-term) or chronic (ongoing).
                
Acute Hypersensitivity Pneumonitis
                
With acute HP, symptoms usually occur within 29 hours of exposure to an antigen you're sensitive to. (An antigen is a substance that your body reacts against, such as molds, dusts, and chemicals.)
                
Acute HP can cause chills, body aches, coughing, and chest tightness. After hours or days of no contact with the antigen, symptoms usually go away.
                
Chronic Hypersensitivity Pneumonitis
                
If acute HP isn't found and treated early, chronic HP may develop. With chronic HP, symptoms occur slowly, over months. Chronic HP can cause a worsening cough, shortness of breath with physical activity, fatigue (tiredness), and weight loss.
                
Some symptoms may continue and/or worsen, even after avoiding the antigen. Chronic HP can cause long-term lung damage, such as pulmonary fibrosis. This is a condition in which tissue deep in your lungs becomes scarred over time.
                
Clubbing also may occur if HP is severe. Clubbing is the widening and rounding of the tips of the fingers or toes. A low level of oxygen in the blood causes this condition.
What are the treatments for Hypersensitivity Pneumonitis ? 
 The best way to treat hypersensitivity pneumonitis (HP) is to avoid the antigen that caused it. (An antigen is a substance that your body reacts against, such as molds, dusts, and chemicals.)
                
In acute (short-term) HP, symptoms usually go away once you're no longer in contact with the antigen. In chronic (ongoing) HP, you may need medicines to relieve your symptoms.
                
People who have chronic HP may develop pulmonary fibrosis. This is a condition in which tissue deep in your lungs becomes scarred over time. People who have this condition may need further treatment, such as oxygen therapy and pulmonary rehabilitation (rehab).
                
Avoiding Antigens
                
Once the antigen that caused the HP and its source are found, you can take steps to avoid it. If HP is caught early, avoiding the antigen may be the only treatment you need.
                
Avoiding an antigen may be easier at home than at work. For example, if your pet bird, moldy carpet, or hot tub is the source of the antigen, you can remove it from your home. If your heating system is the source of the antigen, you can have your system properly serviced.
                
However, if the antigen is at work, you may need to talk with your supervisor about your condition and ways to protect yourself. For example, masks or personal respirators may help protect you from antigens in the air. (A personal respirator is a device that helps filter the air you breathe in.)
                
Some people who have HP may need to move to a different home or change jobs to avoid antigens. After hurricanes, for example, some people have to move from their homes to avoid molds that could harm their lungs. However, moving and changing jobs sometimes isn't possible.
                
Medicines and Other Treatments
                
If you have chronic HP, your doctor may prescribe medicines called corticosteroids. These medicines reduce lung inflammation. Prednisone is an example of a corticosteroid.
                
Long-term use of prednisone, especially at high doses, can cause serious side effects. Thus, if your doctor prescribes this medicine, he or she may reduce the dose over time.
                
Examples of side effects from corticosteroids are increased risk of infections, high blood pressure, high blood sugar, and osteoporosis (thinning of the skin and bones).
                
People who develop pulmonary fibrosis may need medicines, oxygen therapy, and/or pulmonary rehab. Pulmonary fibrosis is a condition in which tissue deep in your lungs becomes scarred over time.
                
If you smoke, try to quit. Smoking can make HP symptoms worse and lead to other lung diseases. Talk with your doctor about programs and products that can help you quit. Also, try to avoid secondhand smoke.
