Question: How to prevent Bronchopulmonary Dysplasia ?
Answer: Taking steps to ensure a healthy pregnancy might prevent your infant from being born before his or her lungs have fully developed. These steps include:
                
Seeing your doctor regularly during your pregnancy
                
Following a healthy diet
                
Not smoking and avoiding tobacco smoke, alcohol, and illegal drugs
                
Controlling any ongoing medical conditions you have
                
Preventing infection
                
If your doctor thinks that you're going to give birth too early, he or she may give you injections of a corticosteroid medicine.
                
The medicine can speed up surfactant production in your baby. Surfactant is a liquid that coats the inside of the lungs. It helps keep them open so your infant can breathe in air once he or she is born.
                
Usually, within about 24 hours of your taking this medicine, the baby's lungs start making enough surfactant. This will reduce the infant's risk of respiratory distress syndrome (RDS), which can lead to bronchopulmonary dysplasia (BPD).
                
Corticosteroids also can help your baby's lungs, brain, and kidneys develop more quickly while he or she is in the womb.
                
If your baby does develop RDS, it will probably be fairly mild. If the RDS isn't mild, BPD will likely develop.

Topic: Hemophilia
Question: What is (are) Hemophilia ?
Answer: Espaol
                
Hemophilia (heem-o-FILL-ee-ah) is a rare bleeding disorder in which the blood doesn't clot normally.
                
If you have hemophilia, you may bleed for a longer time than others after an injury. You also may bleed inside your body (internally), especially in your knees, ankles, and elbows. This bleeding can damage your organs and tissues and may be life threatening.
                
Overview
                
Hemophilia usually is inherited. "Inherited means that the disorder is passed from parents to children through genes.
                
People born with hemophilia have little or no clotting factor. Clotting factor is a protein needed for normal blood clotting. There are several types of clotting factors. These proteins work with platelets (PLATE-lets) to help the blood clot.
                
Platelets are small blood cell fragments that form in the bone marrowa sponge-like tissue in the bones. Platelets play a major role in blood clotting. When blood vessels are injured, clotting factors help platelets stick together to plug cuts and breaks on the vessels and stop bleeding.
                
The two main types of hemophilia are A and B. If you have hemophilia A, you're missing or have low levels of clotting factor VIII (8). About 8 out of 10 people who have hemophilia have type A. If you have hemophilia B, you're missing or have low levels of clotting factor IX (9).
                
Rarely, hemophilia can be acquired. "Acquired means you aren't born with the disorder, but you develop it during your lifetime. This can happen if your body forms antibodies (proteins) that attack the clotting factors in your bloodstream. The antibodies can prevent the clotting factors from working.
                
This article focuses on inherited hemophilia.
                
Outlook
                
Hemophilia can be mild, moderate, or severe, depending on how much clotting factor is in your blood. About 7 out of 10 people who have hemophilia A have the severe form of the disorder.
                
People who don't have hemophilia have a factor VIII activity of 100 percent. People who have severe hemophilia A have a factor VIII activity of less than 1 percent.
                
Hemophilia usually occurs in males (with rare exceptions). About 1 in 5,000 males are born with hemophilia each year.

Topic: Hemophilia
Question: What causes Hemophilia ?
Answer: A defect in one of the genes that determines how the body makes blood clotting factor VIII or IX causes hemophilia. These genes are located on the X chromosomes (KRO-muh-somz).
                
Chromosomes come in pairs. Females have two X chromosomes, while males have one X and one Y chromosome. Only the X chromosome carries the genes related to clotting factors.
                
A male who has a hemophilia gene on his X chromosome will have hemophilia. When a female has a hemophilia gene on only one of her X chromosomes, she is a "hemophilia carrier and can pass the gene to her children. Sometimes carriers have low levels of clotting factor and have symptoms of hemophilia, including bleeding. Clotting factors are proteins in the blood that work together with platelets to stop or control bleeding.
                
Very rarely, a girl may be born with a very low clotting factor level and have a greater risk for bleeding, similar to boys who have hemophilia and very low levels of clotting factor. There are several hereditary and genetic causes of this much rarer form of hemophilia in females.
                
Some males who have the disorder are born to mothers who aren't carriers. In these cases, a mutation (random change) occurs in the gene as it is passed to the child.
                
Below are two examples of how the hemophilia gene is inherited.
                
Inheritance Pattern for HemophiliaExample 1
                

                
Each daughter has a 50 percent chance of inheriting the hemophilia gene from her mother and being a carrier. Each son has a 50 percent chance of inheriting the hemophilia gene from his mother and having hemophilia.
                
Inheritance Pattern for HemophiliaExample 2
                

                
Each daughter will inherit the hemophilia gene from her father and be a carrier. None of the sons will inherit the hemophilia gene from their father; thus, none will have hemophilia.

Topic: Hemophilia
Question: What are the symptoms of Hemophilia ?
Answer: The major signs and symptoms of hemophilia are excessive bleeding and easy bruising.
                
Excessive Bleeding
                
The extent of bleeding depends on how severe the hemophilia is.
                
Children who have mild hemophilia may not have signs unless they have excessive bleeding from a dental procedure, an accident, or surgery. Males who have severe hemophilia may bleed heavily after circumcision.
                
Bleeding can occur on the body's surface (external bleeding) or inside the body (internal bleeding).
                
Signs of external bleeding may include:
                
Bleeding in the mouth from a cut or bite or from cutting or losing a tooth
                
Nosebleeds for no obvious reason
                
Heavy bleeding from a minor cut
                
Bleeding from a cut that resumes after stopping for a short time
                
Signs of internal bleeding may include:
                
Blood in the urine (from bleeding in the kidneys or bladder)
                
Blood in the stool (from bleeding in the intestines or stomach)
                
Large bruises (from bleeding into the large muscles of the body)
                
Bleeding in the Joints
                
Bleeding in the knees, elbows, or other joints is another common form of internal bleeding in people who have hemophilia. This bleeding can occur without obvious injury.
                
At first, the bleeding causes tightness in the joint with no real pain or any visible signs of bleeding. The joint then becomes swollen, hot to touch, and painful to bend.
                
Swelling continues as bleeding continues. Eventually, movement in the joint is temporarily lost. Pain can be severe. Joint bleeding that isn't treated quickly can damage the joint.
                
Bleeding in the Brain
                
Internal bleeding in the brain is a very serious complication of hemophilia. It can happen after a simple bump on the head or a more serious injury. The signs and symptoms of bleeding in the brain include:
                
Long-lasting, painful headaches or neck pain or stiffness
                
Repeated vomiting
                
Sleepiness or changes in behavior
                
Sudden weakness or clumsiness of the arms or legs or problems walking
                
Double vision
                
Convulsions or seizures

Topic: Hemophilia
Question: How to diagnose Hemophilia ?
Answer: If you or your child appears to have a bleeding problem, your doctor will ask about your personal and family medical histories. This will reveal whether you or your family members, including women and girls, have bleeding problems. However, some people who have hemophilia have no recent family history of the disease.
                
You or your child also will likely have a physical exam and blood tests to diagnose hemophilia. Blood tests are used to find out:
                
How long it takes for your blood to clot
                
Whether your blood has low levels of any clotting factors
                
Whether any clotting factors are completely missing from your blood
                
The test results will show whether you have hemophilia, what type of hemophilia you have, and how severe it is.
                
Hemophilia A and B are classified as mild, moderate, or severe, depending on the amount of clotting factor VIII or IX in the blood.
                
The severity of symptoms can overlap between the categories. For example, some people who have mild hemophilia may have bleeding problems almost as often or as severe as some people who have moderate hemophilia.
                
Severe hemophilia can cause serious bleeding problems in babies. Thus, children who have severe hemophilia usually are diagnosed during the first year of life. People who have milder forms of hemophilia may not be diagnosed until they're adults.
                
The bleeding problems of hemophilia A and hemophilia B are the same. Only special blood tests can tell which type of the disorder you or your child has. Knowing which type is important because the treatments are different.
                
Pregnant women who are known hemophilia carriers can have the disorder diagnosed in their unborn babies as early as 12 weeks into their pregnancies.
                
Women who are hemophilia carriers also can have "preimplantation diagnosis" to have children who don't have hemophilia.
                
For this process, women have their eggs removed and fertilized by sperm in a laboratory. The embryos are then tested for hemophilia. Only embryos without the disorder are implanted in the womb.

Topic: Coronary Heart Disease
Question: What is (are) Coronary Heart Disease ?
Answer: Espaol
                
Coronary heart disease (CHD) is a disease in which a waxy substance called plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle.
                
When plaque builds up in the arteries, the condition is called atherosclerosis. The buildup of plaque occurs over many years.
                
Atherosclerosis
                

                
Over time, plaque can harden or rupture (break open). Hardened plaque narrows the coronary arteries and reduces the flow of oxygen-rich blood to the heart.
                
If the plaque ruptures, a blood clot can form on its surface. A large blood clot can mostly or completely block blood flow through a coronary artery. Over time, ruptured plaque also hardens and narrows the coronary arteries.
                
Overview
                
If the flow of oxygen-rich blood to your heart muscle is reduced or blocked, angina or a heart attack can occur.
                
Angina is chest pain or discomfort. It may feel like pressure or squeezing in your chest. The pain also can occur in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion.
                
A heart attack occurs if the flow of oxygen-rich blood to a section of heart muscle is cut off. If blood flow isnt restored quickly, the section of heart muscle begins to die. Without quick treatment, a heart attack can lead to serious health problems or death.
                
Over time, CHD can weaken the heart muscle and lead to heart failure and arrhythmias. Heart failure is a condition in which your heart can't pump enough blood to meet your bodys needs. Arrhythmias are problems with the rate or rhythm of the heartbeat.
                
Outlook
                
Lifestyle changes, medicines, and medical procedures can help prevent or treat coronary heart disease. These treatments may reduce the risk of related health problems.

Topic: Coronary Heart Disease
Question: What causes Coronary Heart Disease ?
Answer: Research suggests that coronary heart disease (CHD) starts when certain factors damage the inner layers of the coronary arteries. These factors include:
                
Smoking
                
High levels of certain fats and cholesterol in the blood
                
High blood pressure
                
High levels of sugar in the blood due to insulin resistance or diabetes
                
Blood vessel inflammation
                
Plaque might begin to build up where the arteries are damaged. The buildup of plaque in the coronary arteries may start in childhood.
                
Over time, plaque can harden or rupture (break open). Hardened plaque narrows the coronary arteries and reduces the flow of oxygen-rich blood to the heart. This can cause angina (chest pain or discomfort).
                
If the plaque ruptures, blood cell fragments called platelets (PLATE-lets) stick to the site of the injury. They may clump together to form blood clots.
                
Blood clots can further narrow the coronary arteries and worsen angina. If a clot becomes large enough, it can mostly or completely block a coronary artery and cause a heart attack.

Topic: Coronary Heart Disease
Question: How to prevent Coronary Heart Disease ?
Answer: You can prevent and control coronary heart disease (CHD)by taking action to control your risk factors with heart-healthy lifestyle changes and medicines. Examples of risk factors you can control include high blood cholesterol, high blood pressure, and overweight and obesity. Only a few risk factorssuch as age, gender, and family historycant be controlled.
                
Your risk for CHD increases with the number of risk factors you have. To reduce your risk of CHD and heart attack, try to control each risk factor you have by adopting the following heart-healthy lifestyles:
                
Heart-healthy eating
                
Maintaining a healthy weight
                
Managing stress
                
Physical activity
                
Quitting smoking
                
Know your family history of health problems related to CHD. If you or someone in your family has CHD, be sure to tell your doctor. If lifestyle changes aren't enough, you also may need medicines to control your CHD risk factors.

Topic: Vasculitis
Question: What is (are) Vasculitis ?
Answer: Vasculitis (vas-kyu-LI-tis) is a condition that involves inflammation in the blood vessels. The condition occurs if your immune system attacks your blood vessels by mistake. This may happen as the result of an infection, a medicine, or another disease or condition.
                
Inflammation refers to the bodys response to injury, including injury to the blood vessels. Inflammation may involve pain, redness, warmth, swelling, and loss of function in the affected tissues.
                
In vasculitis, inflammation can lead to serious problems. Complications depend on which blood vessels, organs, or other body systems are affected.
                
Overview
                
Vasculitis can affect any of the body's blood vessels. These include arteries, veins, and capillaries. Arteries carry blood from your heart to your body's organs. Veins carry blood from your organs and limbs back to your heart. Capillaries connect the small arteries and veins.
                
If a blood vessel is inflamed, it can narrow or close off. This limits or prevents blood flow through the vessel. Rarely, the blood vessel will stretch and weaken, causing it to bulge. This bulge is known as an aneurysm (AN-u-rism).
                
Vasculitis
                

                
The disruption in blood flow caused by inflammation can damage the body's organs. Signs and symptoms depend on which organs have been damaged and the extent of the damage.
                
Typical symptoms of inflammation, such as fever and general aches and pains, are common among people who have vasculitis.
                
Outlook
                
There are many types of vasculitis, but overall the condition is rare. If you have vasculitis, the outlook depends on:
                
The type of vasculitis you have
                
Which organs are affected
                
How quickly the condition worsens
                
The severity of the condition
                
Treatment often works well if its started early. In some cases, vasculitis may go into remission. "Remission" means the condition isn't active, but it can come back, or "flare," at any time.
                
Sometimes vasculitis is chronic (ongoing) and never goes into remission. Long-term treatment with medicines often can control the signs and symptoms of chronic vasculitis.
                
Rarely, vasculitis doesn't respond well to treatment. This can lead to disability and even death.
                
Much is still unknown about vasculitis. However, researchers continue to learn more about the condition and its various types, causes, and treatments.

Topic: Vasculitis
Question: What causes Vasculitis ?
Answer: Vasculitis occurs if your immune system attacks your blood vessels by mistake. What causes this to happen isn't fully known.
                
A recent or chronic (ongoing) infection may prompt the attack. Your body also may attack its own blood vessels in reaction to a medicine.
                
Sometimes an autoimmune disorder triggers vasculitis. Autoimmune disorders occur if the immune system makes antibodies (proteins) that attack and damage the body's own tissues or cells. Examples of these disorders include lupus, rheumatoid arthritis, and scleroderma. You can have these disorders for years before developing vasculitis.
                
Vasculitis also may be linked to certain blood cancers, such as leukemia and lymphoma.

Topic: Vasculitis
Question: What are the symptoms of Vasculitis ?
Answer: The signs and symptoms of vasculitis vary. They depend on the type of vasculitis you have, the organs involved, and the severity of the condition. Some people may have few signs and symptoms. Other people may become very sick.
                
Sometimes the signs and symptoms develop slowly, over months. Other times, the signs and symptoms develop quickly, over days or weeks.
                
Systemic Signs and Symptoms
                
Systemic signs and symptoms are those that affect you in a general or overall way. Common systemic signs and symptoms of vasculitis are:
                
Fever
                
Loss of appetite
                
Weight loss
                
Fatigue (tiredness)
                
General aches and pains
                
Organ- or Body System-Specific Signs and Symptoms
                
Vasculitis can affect specific organs and body systems, causing a range of signs and symptoms.
                
Skin
                
If vasculitis affects your skin, you may notice skin changes. For example, you may have purple or red spots or bumps, clusters of small dots, splotches, bruises, or hives. Your skin also may itch.
                
Joints
                
If vasculitis affects your joints, you may ache or develop arthritis in one or more joints.
                
Lungs
                
If vasculitis affects your lungs, you may feel short of breath. You may even cough up blood. The results from a chest x ray may show signs that suggest pneumonia, even though that may not be what you have.
                
Gastrointestinal Tract
                
If vasculitis affects your gastrointestinal tract, you may get ulcers (sores) in your mouth or have stomach pain.
                
In severe cases, blood flow to the intestines can be blocked. This can cause the wall of the intestines to weaken and possibly rupture (burst). A rupture can lead to serious problems or even death.
                
Sinuses, Nose, Throat, and Ears
                
If vasculitis affects your sinuses, nose, throat, and ears, you may have sinus or chronic (ongoing) middle ear infections. Other symptoms include ulcers in the nose and, in some cases, hearing loss.
                
Eyes
                
If vasculitis affects your eyes, you may develop red, itchy, burning eyes. Your eyes also may become sensitive to light, and your vision may blur. Rarely, certain types of vasculitis may cause blindness.
                
Brain
                
If vasculitis affects your brain, symptoms may include headaches, problems thinking clearly, changes in mental function, or stroke-like symptoms, such as muscle weakness and paralysis (an inability to move).
                
Nerves
                
If vasculitis affects your nerves, you may have numbness, tingling, and weakness in various parts of your body. You also may have a loss of feeling or strength in your hands and feet and shooting pains in your arms and legs.

Topic: Vasculitis
Question: What are the treatments for Vasculitis ?
Answer: Treatment for vasculitis will depend on the type of vasculitis you have, which organs are affected, and the severity of the condition.
                
People who have severe vasculitis are treated with prescription medicines. Rarely, surgery may be done. People who have mild vasculitis may find relief with over-the-counter pain medicines, such as acetaminophen, aspirin, ibuprofen, or naproxen.
                
The main goal of treating vasculitis is to reduce inflammation in the affected blood vessels. This usually is done by reducing or stopping the immune response that caused the inflammation.
                
Types of Treatment
                
Common prescription medicines used to treat vasculitis include corticosteroids and cytotoxic medicines.
                
Corticosteroids help reduce inflammation in your blood vessels. Examples of corticosteroids are prednisone, prednisolone, and methylprednisolone.
                
Doctors may prescribe cytotoxic medicines if vasculitis is severe or if corticosteroids don't work well. Cytotoxic medicines kill the cells that are causing the inflammation. Examples of these medicines are azathioprine, methotrexate, and cyclophosphamide.
                
Your doctor may prescribe both corticosteroids and cytotoxic medicines.
                
Other treatments may be used for certain types of vasculitis. For example, the standard treatment for Kawasaki disease is high-dose aspirin and immune globulin. Immune globulin is a medicine thats injected into a vein.
                
Certain types of vasculitis may require surgery to remove aneurysms that have formed as a result of the condition. (An aneurysm is an abnormal bulge in the wall of a blood vessel.)
