Question: How to prevent Hemolytic Anemia ?
Answer: You can't prevent inherited types of hemolytic anemia. One exception is glucose-6-phosphate dehydrogenase (G6PD) deficiency.
                
If you're born with G6PD deficiency, you can avoid substances that may trigger the condition. For example, avoid fava beans, naphthalene (a substance found in some moth balls), and certain medicines (as your doctor advises).
                
Some types of acquired hemolytic anemia can be prevented. For example, reactions to blood transfusions, which can cause hemolytic anemia, can be prevented. This requires careful matching of blood types between the blood donor and the recipient.
                
Prompt and proper prenatal care can help you avoid the problems of Rh incompatibility. This condition can occur during pregnancy if a woman has Rh-negative blood and her baby has Rh-positive blood. "Rh-negative" and "Rh-positive" refer to whether your blood has Rh factor. Rh factor is a protein on red blood cells.
                
Rh incompatibility can lead to hemolytic anemia in a fetus or newborn.

Question: What causes Hypersensitivity Pneumonitis ?
Answer: 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

Question: Who is at risk for Hypersensitivity Pneumonitis? ?
Answer: 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

Question: What are the symptoms of Hypersensitivity Pneumonitis ?
Answer: 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.

Question: What are the treatments for Hypersensitivity Pneumonitis ?
Answer: 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.

Question: What is (are) Cardiogenic Shock ?
Answer: Cardiogenic (kar-dee-oh-JE-nik) shock is a condition in which a suddenly weakened heart isn't able to pump enough blood to meet the body's needs. The condition is a medical emergency and is fatal if not treated right away.
                
The most common cause of cardiogenic shock is damage to the heart muscle from a severe heart attack. However, not everyone who has a heart attack has cardiogenic shock. In fact, on average, only about 7 percent of people who have heart attacks develop the condition.
                
If cardiogenic shock does occur, it's very dangerous. When people die from heart attacks in hospitals, cardiogenic shock is the most common cause of death.
                
What Is Shock?
                
The medical term "shock" refers to a state in which not enough blood and oxygen reach important organs in the body, such as the brain and kidneys. Shock causes very low blood pressure and may be life threatening.
                
Shock can have many causes. Cardiogenic shock is only one type of shock. Other types of shock include hypovolemic (hy-po-vo-LEE-mik) shock and vasodilatory (VAZ-oh-DILE-ah-tor-e) shock.
                
Hypovolemic shock is a condition in which the heart cant pump enough blood to the body because of severe blood loss.
                
In vasodilatory shock, the blood vessels suddenly relax. When the blood vessels are too relaxed, blood pressure drops and blood flow becomes very low. Without enough blood pressure, blood and oxygen dont reach the bodys organs.
                
A bacterial infection in the bloodstream, a severe allergic reaction, or damage to the nervous system (brain and nerves) may cause vasodilatory shock.
                
When a person is in shock (from any cause), not enough blood and oxygen are reaching the body's organs. If shock lasts more than a few minutes, the lack of oxygen starts to damage the bodys organs. If shock isn't treated quickly, it can cause permanent organ damage or death.
                
Some of the signs and symptoms of shock include:
                
Confusion or lack of alertness
                
Loss of consciousness
                
A sudden and ongoing rapid heartbeat
                
Sweating
                
Pale skin
                
A weak pulse
                
Rapid breathing
                
Decreased or no urine output
                
Cool hands and feet
                
If you think that you or someone else is in shock, call 911 right away for emergency treatment. Prompt medical care can save your life and prevent or limit damage to your bodys organs.
                
Outlook
                
In the past, almost no one survived cardiogenic shock. Now, about half of the people who go into cardiogenic shock survive. This is because of prompt recognition of symptoms and improved treatments, such as medicines and devices. These treatments can restore blood flow to the heart and help the heart pump better.
                
In some cases, devices that take over the pumping function of the heart are used. Implanting these devices requires major surgery.

Question: Who is at risk for Cardiogenic Shock? ?
Answer: The most common risk factor for cardiogenic shock is having a heart attack. If you've had a heart attack, the following factors can further increase your risk for cardiogenic shock:
                
Older age
                
A history of heart attacks or heart failure
                
Coronary heart disease that affects all of the hearts major blood vessels
                
High blood pressure
                
Diabetes
                
Women who have heart attacks are at higher risk for cardiogenic shock than men who have heart attacks.

Topic: Cardiogenic Shock
Source: NHLBI
Question: What are the symptoms of Cardiogenic Shock ?
Answer: A lack of oxygen-rich blood reaching the brain, kidneys, skin, and other parts of the body causes the signs and symptoms of cardiogenic shock.
                
Some of the typical signs and symptoms of shock usually include at least two or more of the following:
                
Confusion or lack of alertness
                
Loss of consciousness
                
A sudden and ongoing rapid heartbeat
                
Sweating
                
Pale skin
                
A weak pulse
                
Rapid breathing
                
Decreased or no urine output
                
Cool hands and feet
                
Any of these alone is unlikely to be a sign or symptom of shock.
                
If you or someone else is having these signs and symptoms, call 911 right away for emergency treatment. Prompt medical care can save your life and prevent or limit organ damage.

Question: How to prevent Cardiogenic Shock ?
Answer: The best way to prevent cardiogenic shock is to lower your risk for coronary heart disease (CHD) and heart attack. (For more information, go to the National Heart, Lung, and Blood Institute's "Your Guide to a Healthy Heart.")
                
If you already have CHD, its important to get ongoing treatment from a doctor who has experience treating heart problems.
                
If you have a heart attack, you should get treatment right away to try to prevent cardiogenic shock and other possible complications.
                
Act in time. Know the warning signs of a heart attack so you can act fast to get treatment. Many heart attack victims wait 2 hours or more after their symptoms begin before they seek medical help. Delays in treatment increase the risk of complications and death.
                
If you think you're having a heart attack, call 911 for help. Don't drive yourself or have friends or family drive you to the hospital. Call an ambulance so that medical personnel can begin life-saving treatment on the way to the emergency room.

Question: What is (are) Aneurysm ?
Answer: An aneurysm (AN-u-rism) is a balloon-like bulge in an artery. Arteries are blood vessels that carry oxygen-rich blood to your body.
                
Arteries have thick walls to withstand normal blood pressure. However, certain medical problems, genetic conditions, and trauma can damage or injure artery walls. The force of blood pushing against the weakened or injured walls can cause an aneurysm.
                
An aneurysm can grow large and rupture (burst) or dissect. A rupture causes dangerous bleeding inside the body. A dissection is a split in one or more layers of the artery wall. The split causes bleeding into and along the layers of the artery wall.
                
Both rupture and dissection often are fatal.
                
Overview
                
Most aneurysms occur in the aorta, the main artery that carries oxygen-rich blood from the heart to the body. The aorta goes through the chest and abdomen.
                
An aneurysm that occurs in the chest portion of the aorta is called a thoracic (tho-RAS-ik) aortic aneurysm. An aneurysm that occurs in the abdominal portion of the aorta is called an abdominal aortic aneurysm.
                
Aneurysms also can occur in other arteries, but these types of aneurysm are less common. This article focuses on aortic aneurysms.
                
About 13,000 Americans die each year from aortic aneurysms. Most of the deaths result from rupture or dissection.
                
Early diagnosis and treatment can help prevent rupture and dissection. However, aneurysms can develop and grow large before causing any symptoms. Thus, people who are at high risk for aneurysms can benefit from early, routine screening.
                
Outlook
                
Doctors often can successfully treat aortic aneurysms with medicines or surgery if theyre found in time. Medicines may be given to lower blood pressure, relax blood vessels, and reduce the risk of rupture.
                
Large aortic aneurysms often can be repaired with surgery. During surgery, the weak or damaged portion of the aorta is replaced or reinforced.

Question: What causes Aneurysm ?
Answer: The force of blood pushing against the walls of an artery combined with damage or injury to the arterys walls can cause an aneurysm.
                
Many conditions and factors can damage and weaken the walls of the aorta and cause aortic aneurysms. Examples include aging, smoking, high blood pressure, and atherosclerosis (ath-er-o-skler-O-sis). Atherosclerosis is the hardening and narrowing of the arteries due to the buildup of a waxy substance called plaque (plak).
                
Rarely, infectionssuch as untreated syphilis (a sexually transmitted infection)can cause aortic aneurysms. Aortic aneurysms also can occur as a result of diseases that inflame the blood vessels, such as vasculitis (vas-kyu-LI-tis).
                
A family history of aneurysms also may play a role in causing aortic aneurysms.
                
In addition to the factors above, certain genetic conditions may cause thoracic aortic aneurysms (TAAs). Examples of these conditions include Marfan syndrome, Loeys-Dietz syndrome, Ehlers-Danlos syndrome (the vascular type), and Turner syndrome.
                
These genetic conditions can weaken the bodys connective tissues and damage the aorta. People who have these conditions tend to develop aneurysms at a younger age than other people. Theyre also at higher risk for rupture and dissection.
                
Trauma, such as a car accident, also can damage the walls of the aorta and lead to TAAs.
                
Researchers continue to look for other causes of aortic aneurysms. For example, theyre looking for genetic mutations (changes in the genes) that may contribute to or cause aneurysms.

Question: Who is at risk for Aneurysm? ?
Answer: Certain factors put you at higher risk for an aortic aneurysm. These factors include:
                
Male gender. Men are more likely than women to have aortic aneurysms.
                
Age. The risk for abdominal aortic aneurysms increases as you get older. These aneurysms are more likely to occur in people who are aged 65 or older.
                
Smoking. Smoking can damage and weaken the walls of the aorta.
                
A family history of aortic aneurysms. People who have family histories of aortic aneurysms are at higher risk for the condition, and they may have aneurysms before the age of 65.
                
A history of aneurysms in the arteries of the legs.
                
Certain diseases and conditions that weaken the walls of the aorta. Examples include high blood pressure and atherosclerosis.
                
Having a bicuspid aortic valve can raise the risk of having a thoracic aortic aneurysm. A bicuspid aortic valve has two leaflets instead of the typical three.
                
Car accidents or trauma also can injure the arteries and increase the risk for aneurysms.
                
If you have any of these risk factors, talk with your doctor about whether you need screening for aneurysms.

Question: What are the symptoms of Aneurysm ?
Answer: The signs and symptoms of an aortic aneurysm depend on the type and location of the aneurysm. Signs and symptoms also depend on whether the aneurysm has ruptured (burst) or is affecting other parts of the body.
                
Aneurysms can develop and grow for years without causing any signs or symptoms. They often don't cause signs or symptoms until they rupture, grow large enough to press on nearby body parts, or block blood flow.
                
Abdominal Aortic Aneurysms
                
Most abdominal aortic aneurysms (AAAs) develop slowly over years. They often don't cause signs or symptoms unless they rupture. If you have an AAA, your doctor may feel a throbbing mass while checking your abdomen.
                
When symptoms are present, they can include:
                
A throbbing feeling in the abdomen
                
Deep pain in your back or the side of your abdomen
                
Steady, gnawing pain in your abdomen that lasts for hours or days
                
If an AAA ruptures, symptoms may include sudden, severe pain in your lower abdomen and back; nausea (feeling sick to your stomach) and vomiting; constipation and problems with urination; clammy, sweaty skin; light-headedness; and a rapid heart rate when standing up.
                
Internal bleeding from a ruptured AAA can send you into shock. Shock is a life-threatening condition in which blood pressure drops so low that the brain, kidneys, and other vital organs can't get enough blood to work well. Shock can be fatal if its not treated right away.
                
Thoracic Aortic Aneurysms
                
A thoracic aortic aneurysm (TAA) may not cause symptoms until it dissects or grows large. If you have symptoms, they may include:
                
Pain in your jaw, neck, back, or chest
                
Coughing and/or hoarseness
                
Shortness of breath and/or trouble breathing or swallowing
                
A dissection is a split in one or more layers of the artery wall. The split causes bleeding into and along the layers of the artery wall.
                
If a TAA ruptures or dissects, you may feel sudden, severe, sharp or stabbing pain starting in your upper back and moving down into your abdomen. You may have pain in your chest and arms, and you can quickly go into shock.
                
If you have any symptoms of TAA or aortic dissection, call 911. If left untreated, these conditions may lead to organ damage or death.

Question: How to diagnose Aneurysm ?
Answer: If you have an aortic aneurysm but no symptoms, your doctor may find it by chance during a routine physical exam. More often, doctors find aneurysms during tests done for other reasons, such as chest or abdominal pain.
                
If you have an abdominal aortic aneurysm (AAA), your doctor may feel a throbbing mass in your abdomen. A rapidly growing aneurysm about to rupture (burst) can be tender and very painful when pressed. If you're overweight or obese, it may be hard for your doctor to feel even a large AAA.
                
If you have an AAA, your doctor may hear rushing blood flow instead of the normal whooshing sound when listening to your abdomen with a stethoscope.
                
Specialists Involved
                
Your primary care doctor may refer you to a cardiothoracic or vascular surgeon for diagnosis and treatment of an aortic aneurysm.
                
A cardiothoracic surgeon does surgery on the heart, lungs, and other organs and structures in the chest, including the aorta. A vascular surgeon does surgery on the aorta and other blood vessels, except those of the heart and brain.
                
Diagnostic Tests and Procedures
                
To diagnose and study an aneurysm, your doctor may recommend one or more of the following tests.
                
Ultrasound and Echocardiography
                
Ultrasound and echocardiography (echo) are simple, painless tests that use sound waves to create pictures of the structures inside your body. These tests can show the size of an aortic aneurysm, if one is found.
                
Computed Tomography Scan
                
A computed tomography scan, or CT scan, is a painless test that uses x rays to take clear, detailed pictures of your organs.
                
During the test, your doctor will inject dye into a vein in your arm. The dye makes your arteries, including your aorta, visible on the CT scan pictures.
                
Your doctor may recommend this test if he or she thinks you have an AAA or a thoracic aortic aneurysm (TAA). A CT scan can show the size and shape of an aneurysm. This test provides more detailed pictures than an ultrasound or echo.
                
Magnetic Resonance Imaging
                
Magnetic resonance imaging (MRI) uses magnets and radio waves to create pictures of the organs and structures in your body. This test works well for detecting aneurysms and pinpointing their size and exact location.
                
Angiography
                
Angiography (an-jee-OG-ra-fee) is a test that uses dye and special x rays to show the insides of your arteries. This test shows the amount of damage and blockage in blood vessels.
                
Aortic angiography shows the inside of your aorta. The test may show the location and size of an aortic aneurysm.
