<s>[INST] What are the symptoms of Allergy? [/INST] Allergy symptoms vary, but may include:
Breathing problems (coughing, shortness of breath) Burning, tearing, or itchy eyes Conjunctivitis (red, swollen eyes) Coughing Diarrhea Headache Hives Itching of the nose, mouth, throat, skin, or any other area Runny nose Skin rashes Stomach cramps Vomiting Wheezing
What part of the body is contacted by the allergen plays a role in the symptoms you develop. For example:
Allergens that are breathed in often cause a stuffy nose, itchy nose and throat, mucus production, cough, or wheezing. Allergens that touch the eyes may cause itchy, watery, red, swollen eyes. Eating something you are allergic to can cause nausea, vomiting, abdominal pain, cramping, diarrhea, or a severe, life-threatening reaction. Allergens that touch the skin can cause a skin rash, hives, itching, blisters, or even skin peeling. Drug allergies usually involve the whole body and can lead to a variety of symptoms. </s> |
<s>[INST] What causes Allergy? [/INST] The immune system normally protects the body against harmful substances, such as bacteria and viruses. It also reacts to foreign substances called allergens, which are generally harmless and in most people do not cause a problem.But in a person with allergies, the immune response is oversensitive. When it recognizes an allergen, it releases chemicals such as histamines. which fight off the allergen. This causes itching, swelling, mucus production, muscle spasms, hives, rashes, and other symptoms, which vary from person to person.
Common allergens include pollen, mold, pet dander, and dust. Food and drug allergies are common. Allergic reactions can also be caused by insect bites, jewelry, cosmetics, spices, and other substances.Some people have allergy-like reactions to hot or cold temperatures, sunlight, or other environmental triggers.
Sometimes, friction (rubbing or roughly stroking the skin) will cause symptoms.A specific allergy is not usually passed down through families (inherited). However, if both your parents have allergies, you are likely to have allergies. The chance is greater if your mother has allergies.
Allergies may make certain medical conditions such as sinus problems, eczema, and asthma worse.Allergies are relatively common. Both genetics and environmental factors play a role. </s> |
<s>[INST] When to seek urgent medical care when I have Allergy ? [/INST] Call for an appointment with your health care provider if:
Severe symptoms of allergy occur. Treatment for allergies no longer works. </s> |
<s>[INST] What to expect if I have Allergy (Outlook/Prognosis)? [/INST] Most allergies can be easily treated with medication. Some children may outgrow an allergy. This is particularly true of food allergies. However, as a general rule, once a substance has triggered an allergic reaction, it continues to affect the person.
Allergy shots are most effective when used to treat those with hay fever symptoms and severe insect sting allergies. They are not used to treat food allergies because of the danger of a severe reaction. Allergy shots may require years of treatment, but they work in most cases. However, they may cause uncomfortable side effects (such as hives and rash) and dangerous outcomes (such as anaphylaxis). </s> |
<s>[INST] What are the symptoms of Anaphylaxis? [/INST] Symptoms develop rapidly, often within seconds or minutes. They may include the following:
Abdominal pain or cramping Abnormal (high-pitched) breathing sounds Anxiety Confusion Cough Diarrhea Difficulty breathing Difficulty swallowing Fainting, light-headedness, dizziness Hives, itchiness Nasal congestion Nausea, vomiting Palpitations Skin redness Slurred speech Wheezing </s> |
<s>[INST] What causes Anaphylaxis? [/INST] Anaphylaxis is a severe, whole-body allergic reaction to a chemical that has become an allergen. After being exposed to a substance such as bee sting venom, the person's immune system becomes sensitized to it. On a later exposure to that allergen, an allergic reaction may occur. This reaction happens quickly after the exposure, is severe, and involves the whole body.
Tissues in different parts of the body release histamine and other substances. This causes the airways to tighten and leads to other symptoms.
Some drugs (morphine, x-ray dye, and others) may cause an anaphylactic-like reaction (anaphylactoid reaction) when people are first exposed to them. Aspirin may also cause a reaction. These reactions are not the same as the immune system response that occurs with "true" anaphylaxis. However, the symptoms, risk for complications, and treatment are the same for both types of reactions.
Anaphylaxis can occur in response to any allergen. Common causes include:
Drug allergies Food allergies Insect bites/stings
Pollens and other inhaled allergens rarely cause anaphylaxis. Some people have an anaphylactic reaction with no known cause.
Anaphylaxis is life-threatening and can occur at any time. Risks include a history of any type of allergic reaction. </s> |
<s>[INST] When to seek urgent medical care when I have Anaphylaxis ? [/INST] Call 911 if you develop severe symptoms of anaphylaxis. If you are with another person, he or she may take you to the nearest emergency room. </s> |
<s>[INST] What to expect if I have Anaphylaxis (Outlook/Prognosis)? [/INST] Anaphylaxis is a severe disorder that can be life-threatening without prompt treatment. However, symptoms usually get better with the right therapy, so it is important to act right away. </s> |
<s>[INST] What are the symptoms of Angioedema? [/INST] The main symptom is sudden swelling below the skin surface. You may also develop welts or swelling on the surface of your skin. The swelling usually occurs around the eyes and lips. It may also be found on the hands, feet, and throat. The swelling may form a line or be more spread out. The welts are painful and may be itchy. They turn pale and swell if irritated. The deeper swelling of angioedema may also be painful.
Other symptoms may include:
Abdominal cramping. Breathing difficulty. Swollen eyes and mouth. Swollen lining of the eyes (chemosis). </s> |
<s>[INST] What causes Angioedema? [/INST] Angioedema may be caused by an allergic reaction. During the reaction, histamine and other chemicals are released into the bloodstream. The body releases histamine when the immune system detects a foreign substance called an allergen.
In many cases, the cause of angioedema is never found. The following may cause angioedema:
Animal dander (scales of shed skin). Exposure to water, sunlight, cold or heat. Foods (such as berries, shellfish, fish, nuts, eggs, milk, and others). Insect bites. Medications (drug allergy), such as antibiotics (penicillin and sulfa drugs), nonsteroidal anti-inflammatory drugs (NSAIDs), and blood pressure medicines (ACE inhibitors). Pollen.
Hives and angioedema may also occur after infections or with other illnesses (including autoimmune disorders such as lupus, and leukemia and lymphoma). A form of angioedema runs in families and has different triggers, complications, and treatments. This is called hereditary angioedema, and it is not discussed in this article. </s> |
<s>[INST] When to seek urgent medical care when I have Angioedema ? [/INST] Call your health care provider if:
Angioedema does not respond to treatment It is severe You have never had angioedema before
Go to the emergency room or call the local emergency number (such as 911) if you have:
Abnormal breathing sounds (stridor) Difficulty breathing Fainting Wheezing </s> |
<s>[INST] What to expect if I have Angioedema (Outlook/Prognosis)? [/INST] Angioedema that does not affect the breathing may be uncomfortable, but is usually harmless and goes away in a few days. </s> |
<s>[INST] What are the symptoms of Asthma? [/INST] Most people with asthma have attacks separated by symptom-free periods. Some people have long-term shortness of breath with episodes of increased shortness of breath. Either wheezing or a cough may be the main symptom.
Asthma attacks can last for minutes to days, and can become dangerous if the airflow is severely restricted.
Cough with or without sputum (phlegm) production Pulling in of the skin between the ribs when breathing (intercostal retractions) Shortness of breath that gets worse with exercise or activity Wheezing: Comes in episodes with symptom-free periods in between May be worse at night or in early morning May go away on its own Gets better when using drugs that open the airways (bronchodilators) Gets worse when breathing in cold air Gets worse with exercise Gets worse with heartburn (reflux) Usually begins suddenly
Bluish color to the lips and face Decreased level of alertness such as severe drowsiness or confusion, during an asthma attack Extreme difficulty breathing Rapid pulse Severe anxiety due to shortness of breath Sweating
Abnormal breathing pattern (breathing out takes more than twice as long as breathing in) Breathing temporarily stops Chest pain Nasal flaring Tightness in the chest </s> |
<s>[INST] What causes Asthma? [/INST] Asthma is caused by inflammation in the airways. When an asthma attack occurs, the muscles surrounding the airways become tight and the lining of the air passages swells. This reduces the amount of air that can pass by.
In sensitive individuals, asthma symptoms can be triggered by breathing in allergy-causing substances (called allergens or triggers).
Common asthma triggers include:
Animals (pet hair or dander) Dust Changes in weather (most often cold weather) Chemicals in the air or in food Exercise Mold Pollen Respiratory infections, such as the common cold Strong emotions (stress) Tobacco smoke
Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) provoke asthma in some patients. </s> |
<s>[INST] Who is at highest risk for Asthma ? [/INST] Many people with asthma have an individual or family history of allergies, such as hay fever (allergic rhinitis) or eczema. Others have no history of allergies. </s> |
<s>[INST] When to seek urgent medical care when I have Asthma ? [/INST] Call for an appointment with your health care provider if asthma symptoms develop. Call your health care provider or go to the emergency room if:
An asthma attack requires more medication than recommended Symptoms get worse or do not improve with treatment You have shortness of breath while talking Your peak flow measurement is 50-80% of your personal best
Go to the emergency room if:
Drowsiness or confusion develops There is severe shortness of breath at rest The peak flow measurement is less than 50% of your personal best You have severe chest pain </s> |
<s>[INST] What to expect if I have Asthma (Outlook/Prognosis)? [/INST] There is no cure for asthma, although symptoms sometimes improve over time. With proper self management and medical treatment, most people with asthma can lead normal lives. </s> |
<s>[INST] What are the symptoms of dermatitis herpetiformis? [/INST] Dermatitis herpetiformis is usually extremely itchy. The bumps or blisters usually appear on the elbows, knees, back, and buttocks. In most cases, the rash is the same size and shape on both sides. Symptoms of dermatitis herpetiformis tend to come and go. </s> |
<s>[INST] What causes dermatitis herpetiformis? [/INST] The cause is unknown. However, dermatitis herpetiformis is frequently linked to gluten sensitivity (celiac sprue disease) in the small bowel. </s> |
<s>[INST] Who is at highest risk for Dermatitis herpetiformis ? [/INST] Dermatitis herpetiformis occurs in both men and women, usually of age 20 years and older. Although children may be sometimes affected. </s> |
<s>[INST] When to seek urgent medical care when I have Dermatitis herpetiformis ? [/INST] Call your health care provider if the rash is non- resolving despite of the treatment. </s> |
<s>[INST] What to expect if I have Dermatitis herpetiformis (Outlook/Prognosis)? [/INST] Dermatitis herpetiformis is an autoimmune disorder which is strongly associated with celiac disease, which also affects the small intestine. The rash can be controlled with gluten free diet and an inability to adhere to the diet increase the risk of intestinal cancer. </s> |
<s>[INST] What are the symptoms of Drug allergy? [/INST] Anaphylaxis, or severe allergic reaction (see below). Hives. Itching of the skin or eyes (common). Skin rash (common). Swelling of the lips, tongue, or face. Wheezing.
Symptoms of anaphylaxis include:
Abdominal pain or cramping. Confusion. Diarrhea. Difficulty breathing with wheeze or hoarse voice. Dizziness. Fainting, lightheadedness. Hives over different parts of the body. Nausea, vomiting. Rapid pulse. Sensation of feeling the heart beat (palpitations). </s> |
<s>[INST] What causes Drug allergy? [/INST] Adverse reactions to drugs are common, and almost any drug can cause an adverse reaction. Reactions range from irritating or mild side effects such as nausea and vomiting to life-threatening anaphylaxis.
A true drug allergy results from a series of chemical steps within the body that produce the allergic reaction to a medication.
It can develop two different ways:
The first time you take the medicine, you have no problems, but your body's immune system produces a substance (antibody) called IgE against that drug. The next time you take the drug, the IgE tells your white blood cells to make a chemical called histamine, which causes your allergy symptoms. A drug allergy may also occur without your body producing IgE, but this is not well understood.
Most drug allergies cause minor skin rashes and hives. Serum sickness is a delayed type of drug allergy that occurs a week or more after exposure to a medication or vaccine.
Penicillin and related antibiotics are the most common cause of drug allergies. Other common allergy-causing drugs include:
Sulfa drugs. Anticonvulsants. Insulin preparations (particularly animal sources of insulin). Iodinated (containing iodine) x-ray contrast dyes (these can cause allergy-like anaphylactoid reactions).
Most side effects of drugs are not due to an allergic reaction. For example, aspirin can cause nonallergic hives or trigger asthma. Some drug reactions are considered "idiosyncratic." This means the reaction is an unusual effect of the medication, not due to a predictable chemical effect of the drug. Many people confuse an uncomfortable, but not serious, side effect of a medicine (such as nausea) with a true drug allergy, which can be life threatening. </s> |
<s>[INST] When to seek urgent medical care when I have Drug allergy ? [/INST] Call your health care provider if you are taking a medication and seem to be having a reaction to it.
Go to the emergency room or call the local emergency number (such as 911) if you have difficulty breathing or develop other symptoms of severe asthma or anaphylaxis. These are emergency conditions. </s> |
<s>[INST] What to expect if I have Drug allergy (Outlook/Prognosis)? [/INST] Most drug allergies respond readily to treatment. A few cases cause severe asthma, anaphylaxis, or death. </s> |
<s>[INST] What are the symptoms of Food allergy? [/INST] Symptoms usually begin immediately, within 2 hours after eating. Rarely, the symptoms may begin hours after eating the offending food.
If you develop symptoms shortly after eating a specific food, you may have a food allergy. Key symptoms include hives, hoarse voice, and wheezing.
Other symptoms that may occur include:
Abdominal pain. Diarrhea. Difficulty swallowing. Itching of the mouth, throat, eyes, skin, or any area. Lightheadedness or fainting. Nasal congestion. Nausea. Runny nose. Patches of itchy, scaly skin (atopic dermatitis); skin may peel or blister. Swelling (angioedema), especially of the eyelids, face, lips, and tongue. Shortness of breath. Stomach cramps. Vomiting.
Symptoms of mouth (oral) allergy syndrome:
Itchy lips, tongue, and throat. Swollen lips (sometimes). </s> |
<s>[INST] What causes Food allergy? [/INST] Normally, your body's immune system defends against potentially harmful substances, such as bacteria, viruses, and toxins. In some people, an immune response is triggered by a substance that is generally harmless, such as a specific food.
The cause of food allergies is related to your body making a type of allergy-producing substance called immunoglobulin E (IgE) antibodies to a particular food.
Although many people have a food intolerance, food allergies are less common. In a true food allergy, the immune system produces antibodies and histamine in response to the specific food.
Any food can cause an allergic reaction, but a few foods are the main culprits. In children, the most common food allergies are to:
Eggs. Milk. Peanuts. Shellfish (shrimp, crab, lobster). Soy. Tree nuts. Wheat.
A food allergy frequently starts in childhood, but it can begin at any age. Fortunately, many children will outgrow their allergy to milk, egg, wheat, and soy by the time they are 5 years old if they avoid the offending foods when they are young. Allergies to peanuts, tree nuts, and shellfish tend to be lifelong.
In older children and adults, the most common food allergies are:
Fish. Peanuts. Shellfish. Tree nuts.
Food additives -- such as dyes, thickeners, and preservatives – may rarely cause an allergic or intolerance reaction.
An allergy syndrome that affects the mouth and tongue may occur after eating certain fresh fruits and vegetables. These foods contain substances similar to certain pollens. For example, melon contains substances similar to ragweed pollen, and apples have allergens similar to tree pollen.
Many Americans believe they have food allergies, while in reality fewer than 1% have true allergies. Most symptoms are caused by intolerances to foods such as:
Corn products. Cow's milk and dairy products. Wheat and other gluten-containing grains. </s> |
<s>[INST] When to seek urgent medical care when I have Food allergy ? [/INST] Call your local emergency number, such as 911, if you have any serious or whole-body reactions (particularly wheezing or difficulty breathing) after eating a food. If your doctor prescribed epinephrine for severe reactions, inject it as soon as possible, even before calling 911. The sooner you inject the epinephrine, the better. Anyone who has had an allergic reaction to a food should be evaluated by an allergy specialist. </s> |
<s>[INST] What to expect if I have Food allergy (Outlook/Prognosis)? [/INST] Avoiding the offending foods may be easy if the food is uncommon or easily identified. However, you may need to severely restrict your diet, carefully read all package ingredients, and ask detailed questions when eating away from home. </s> |
<s>[INST] What are the symptoms of Hay fever? [/INST] Symptoms that occur shortly after you come into contact with the substance you are allergic to may include:
Itchy nose, mouth, eyes, throat, skin, or any area Problems with smell Runny nose Sneezing Tearing eyes
Symptoms that may develop later include:
Stuffy nose (nasal congestion) Coughing Clogged ears and decreased sense of smell Sore throat Dark circles under the eyes Puffiness under the eyes Fatigue and irritability Headache Memory problems and slowed thinking </s> |
<s>[INST] What causes Hay fever? [/INST] An allergen is something that triggers an allergy. When a person with allergic rhinitis breathes in an allergen such as pollen or dust, the body releases chemicals, including histamine. This causes allergy symptoms such as itching, swelling, and mucus production.
Hay fever involves an allergic reaction to pollen. (A similar reaction occurs with allergy to mold, animal dander, dust, and similar inhaled allergens.)
The pollens that cause hay fever vary from person to person and from region to region. Large, visible pollens are seldom responsible for hay fever. Tiny, hard to see pollens more often cause hay fever. Examples of plants commonly responsible for hay fever include:
Trees (deciduous and evergreen) Grasses Ragweed
The amount of pollen in the air can play a role in whether hay fever symptoms develop. Hot, dry, windy days are more likely to have increased amounts of pollen in the air than cool, damp, rainy days when most pollen is washed to the ground.
Some disorders may be associated with allergies. These include eczema and asthma.
Allergies are common. Your genes and environment may make you more prone to allergies. </s> |
<s>[INST] Who is at highest risk for Hay fever? [/INST] Whether or not you are likely to develop allergies is often passed down through families. If both your parents have allergies, you are likely to have allergies. The chance is greater if your mother has allergies. </s> |
<s>[INST] When to seek urgent medical care when I have Hay fever ? [/INST] Call for an appointment with your health care provider if severe symptoms of allergies or hay fever occur, if previously successful treatment has become ineffective, or if your symptoms do not respond to treatment. </s> |
<s>[INST] What to expect if I have Hay fever (Outlook/Prognosis)? [/INST] Most symptoms of allergic rhinitis can be treated. More severe cases require allergy shots.
Some people (particularly children) may outgrow an allergy as the immune system becomes less sensitive to the allergen. However, as a general rule, once a substance causes allergies for an individual, it can continue to affect the person over the long term. </s> |
<s>[INST] What are the symptoms of Hypersensitivity pneumonitis? [/INST] Symptoms of acute hypersensitivity pneumonitis may occur 4 - 6 hours after you have left the area where the foreign substance is found, making it difficult to find a connection between your activity and the disease.
Symptoms may include:
Chills. Cough. Fever. Malaise (feeling ill). Shortness of breath.
Symptoms of chronic hypersensitivity pneumonitis may include:
Breathlessness, especially with activity. Cough, often dry. Loss of appetite. Unintentional weight loss. </s> |
<s>[INST] What causes Hypersensitivity pneumonitis? [/INST] Hypersensitivity pneumonitis usually occurs in people who work in places where there are high levels of organic dusts, fungus, or molds. Bird fancier's lung is the most common type of hypersensitivity pneumonitis. It is caused by repeated or intense exposure to proteins found in the feathers or droppings of many species of birds.
Farmer's lung is caused by exposure to dust from moldy hay, straw, and grain. These exposures can lead to lung inflammation and acute lung disease. Over time, this acute Hypersensitivity pneumonitis may turn into long-lasting (chronic) lung disease.
Hypersensitivity pneumonitis may also be caused by fungi or bacteria in humidifiers, heating systems, and air Hypersensitivity pneumonitisers found in homes and offices. Exposure to certain chemicals, such as isocyanates or acid anhydrides, can also lead to hypersensitivity pneumonitis. </s> |
<s>[INST] When to seek urgent medical care when I have Hypersensitivity pneumonitis ? [/INST] Call your health care provider if you develop symptoms of hypersensitivity pneumonitis. </s> |
<s>[INST] What to expect if I have Hypersensitivity pneumonitis (Outlook/Prognosis)? [/INST] Most symptoms go away when you avoid or limit your exposure to the material that caused the problem. </s> |
<s>[INST] How is the Skin allergy testing done? [/INST] There are many methods of allergy testing. Among the more common are:
Skin tests. Elimination-type tests. Blood tests (including the radioallergosorbent, or RAST, test).
SKIN TESTS
Skin tests are the most common. Specific methods vary.
One of the most common methods is the prick test. This test involves placing a small amount of suspectedallergy-causing substances on the skin, usually the forearm, upper arm, or the back. Then, the skin is pricked so the allergen goes under the skin's surface. The health care provider closely watches the skin for signs of a reaction, usually swelling and redness of the site. Results are usually seen within 15-20 minutes. Several allergens can be tested at the same time.
A similar method involves injecting a small amount of allergen into the skin and watching for a reaction at the site. This is called an intradermal skin test. It is more likely to be used when testing is being done to find out if you are allergy to something specific, such as bee venom or penicillin.
Patch testing is a method to diagnose allergic reactions on the skin. Possible allergens are taped to the skin for 48 hours. The health care provider will look at the area in 24 hours, and then again 48 hours later.
Skin tests are most useful for diagnosing:
Food allergy. Mold, pollen, animal, and other allergies that cause allergic rhinitis and asthma. Penicillin allergy. Venom allergy. Allergic contact dermatitis.
ELIMINATION TESTS
An elimination diet can be used to check for food allergies. An elimination diet is one in which foods that may be causing symptoms are removed from the diet for several weeks and then slowly re-introduced one at a time while the person is watched for signs of an allergic reaction.
BLOOD TESTS
Blood tests can be done to measure the amount of immunoglobulin (Ig) E antibodies to a specific allergen in the blood. This test may be used when skin testing is not helpful or cannot be done
Other blood tests include:
Absolute eosinophil count. Total IgE level.
PROVOCATION
Provocation (challenge) testing involves exposing a person to a suspected allergen under controlled circumstances. This may be done in the diet or by breathing in the suspected allergen. This type of test may provoke severe allergic reactions. Challenge testing should only be done by a doctor.
Another method is the double-blind test. This method involves giving foods and harmless substances in a disguised form. The person being tested and the provider are both unaware of whether the substance tested in that session is the harmless substance or the suspected food. A third party knows the identity of the substances and identifies them with some sort of code. This test requires several sessions if more than one substance is under investigation.
While the double-blind strategy is useful and practical for mild allergic reactions, it must be done carefully in individuals with suspected severe reactions to foods. Blood tests may be a safer first approach.
Skin tests may cause very mild discomfort when the skin is pricked. Itching may occur if you have a positive reaction to the allergen. </s> |
<s>[INST] Who needs Skin allergy testing? [/INST] Allergy tests are done to determine the specific substances that cause an allergic reaction in a person.
Your doctor may order allergy tests if you have:
Allergic rhinitis and asthma symptoms that are not easily controlled with medications. Angioedema and hives. Food allergies. Contact dermatitis. Penicillin allergy.
NOTE: Allergies to penicillin and closely related medications are the only drug allergies that can be tested using skin tests. Skin tests for allergies to other drugs can be dangerous.
The prick skin test may also be used to diagnose food allergies. Intradermal tests are not used to test for food allergies because of high false positive results and the danger of causing a severe allergic reaction. </s> |
<s>[INST] Where to find centers that perform Skin allergy testing? [/INST] Directions to Hospitals Performing Skin allergy testing </s> |
<s>[INST] What to expect if I have Skin allergy testing (Outlook/Prognosis)? [/INST] Normal Results
In a nonallergic person, allergy tests should be negative (no response to the allergen).
Abnormal Results
A positive result means you reacted to a specific substance. Often, but not always, a positive result means the symptoms that you are having are due to exposure to the substance in question. In general, a stronger response means you are more sensitive to the substance.
People can have a positive response with allergy skin testing, but not have any problems with the specific substance in every day life.
The skin tests are generally reliable. However, if the dose of allergen is excessive, a positive reaction will occur even in persons who are not allergic. </s> |
<s>[INST] What are the symptoms of Urticaria ? [/INST] Itching Swelling of the surface of the skin into red- or skin-colored welts (called wheals) with clearly defined edges.
The hives may get bigger, spread, and join together to form larger areas of flat, raised skin.
They can also change shape, disappear, and reappear within minutes or hours. A true hive comes and goes. When you press the center of one, it turns white. This is called blanching. </s> |
<s>[INST] What are the causes of Urticaria ? [/INST] When you have an allergic reaction to a substance, your body releases histamine and other chemicals into your bloodstream. This causes itching, swelling, and other symptoms. Hives are a common reaction, especially in people with other allergies such as hay fever.
When swelling or welts occur around the face, especially the lips and eyes, it is called angioedema. Swelling from angioedema can also occur around your hands, feet, and throat.
Many substances can trigger hives, including:
Animal dander (especially cats) Insect bites Medications Pollen Shellfish, fish, nuts, eggs, milk, and other foods
Hives may also develop as a result of:
Emotional stress Extreme cold or sun exposure Excessive perspiration Illness (including lupus, other autoimmune diseases, and leukemia Infections such as mononucleosis </s> |
<s>[INST] When to seek urgent medical care when I have Urticaria ? [/INST] Call 911 or your local emergency number if you have:
Fainting Shortness of breath Tightness in your throat Tongue or face swelling Wheezing
Call your health care provider if the hives are severe, uncomfortable, and do not respond to self-care measures. </s> |
<s>[INST] What to expect if I have Urticaria (Outlook/Prognosis)? [/INST] Hives may be uncomfortable, but they generally are harmless and disappear on their own. In most cases, the exact cause of hives cannot be identified. </s> |

<s>[INST] What to expect if I have Malignant hyperthermia (Outlook/Prognosis)? [/INST] Repeated episodes or untreated episodes can cause kidney failure. Untreated episodes can be fatal. </s> |
<s>[INST] How is Pain Treated? [/INST] The goal of pain management is to improve function, enabling individuals to work, attend school, or participate in other day-to-day activities. Patients and their physicians have a number of options for the treatment of pain; some are more effective than others. Sometimes, relaxation and the use of imagery as a distraction provide relief. These methods can be powerful and effective, according to those who advocate their use. Whatever the treatment regime, it is important to remember that pain is treatable. The following treatments are among the most common.
Acetaminophen is the basic ingredient found in Tylenol® and its many generic equivalents. It is sold over the counter, in a prescription-strength preparation, and in combination with codeine (also by prescription).
Acupuncture dates back 2,500 years and involves the application of needles to precise points on the body. It is part of a general category of healing called traditional Chinese or Oriental medicine. Acupuncture remains controversial but is quite popular and may one day prove to be useful for a variety of conditions as it continues to be explored by practitioners, patients, and investigators.
Analgesic refers to the class of drugs that includes most painkillers, such as aspirin, acetaminophen, and ibuprofen. The word analgesic is derived from ancient Greek and means to reduce or stop pain. Nonprescription or over-the-counter pain relievers are generally used for mild to moderate pain. Prescription pain relievers, sold through a pharmacy under the direction of a physician, are used for more moderate to severe pain.
Anticonvulsants are used for the treatment of seizure disorders but are also sometimes prescribed for the treatment of pain. Carbamazepine in particular is used to treat a number of painful conditions, including trigeminal neuralgia. Another antiepileptic drug, gabapentin, is being studied for its pain-relieving properties, especially as a treatment for neuropathic pain.
Antidepressants are sometimes used for the treatment of pain and, along with neuroleptics and lithium, belong to a category of drugs called psychotropic drugs. In addition, anti-anxiety drugs called benzodiazepines also act as muscle relaxants and are sometimes used as pain relievers. Physicians usually try to treat the condition with analgesics before prescribing these drugs.
Antimigraine drugs include the triptans- sumatriptan (Imitrex®), naratriptan (Amerge®), and zolmitriptan (Zomig®)-and are used specifically for migraine headaches. They can have serious side effects in some people and therefore, as with all prescription medicines, should be used only under a doctor's care.
Aspirin may be the most widely used pain-relief agent and has been sold over the counter since 1905 as a treatment for fever, headache, and muscle soreness.
Biofeedback is used for the treatment of many common pain problems, most notably headache and back pain. Using a special electronic machine, the patient is trained to become aware of, to follow, and to gain control over certain bodily functions, including muscle tension, heart rate, and skin temperature. The individual can then learn to effect a change in his or her responses to pain, for example, by using relaxation techniques. Biofeedback is often used in combination with other treatment methods, generally without side effects. Similarly, the use of relaxation techniques in the treatment of pain can increase the patient's feeling of well-being.
Capsaicin is a chemical found in chili peppers that is also a primary ingredient in pain-relieving creams (see Chili Peppers, Capsaicin, and Pain in the Appendix).
Chemonucleolysis is a treatment in which an enzyme, chymopapain, is injected directly into a herniated lumbar disc (see Spine Basics in the Appendix) in an effort to dissolve material around the disc, thus reducing pressure and pain. The procedure's use is extremely limited, in part because some patients may have a life-threatening allergic reaction to chymopapain.
Chiropractic care may ease back pain, neck pain, headaches, and musculoskeletal conditions. It involves "hands-on" therapy designed to adjust the relationship between the body's structure (mainly the spine) and its functioning. Chiropractic spinal manipulation includes the adjustment and manipulation of the joints and adjacent tissues. Such care may also involve therapeutic and rehabilitative exercises.
Cognitive-behavioral therapy involves a wide variety of coping skills and relaxation methods to help prepare for and cope with pain. It is used for postoperative pain, cancer pain, and the pain of childbirth.
Counseling can give a patient suffering from pain much needed support, whether it is derived from family, group, or individual counseling. Support groups can provide an important adjunct to drug or surgical treatment. Psychological treatment can also help patients learn about the physiological changes produced by pain.
COX-2 inhibitors may be effective for individuals with arthritis. For many years scientists have wanted to develop a drug that works as well as morphine but without its negative side effects. Nonsteroidal anti-inflammatory drugs (NSAIDs) work by blocking two enzymes, cyclooxygenase-1 and cyclooxygenase-2, both of which promote production of hormones called prostaglandins, which in turn cause inflammation, fever, and pain. The newer COX-2 inhibitors primarily block cyclooxygenase-2 and are less likely to have the gastrointestinal side effects sometimes produced by NSAIDs.
In 1999, the Food and Drug Administration approved a COX-2 inhibitor-celecoxib-for use in cases of chronic pain. The long-term effects of all COX-2 inhibitors are still being evaluated, especially in light of new information suggesting that these drugs may increase the risk of heart attack and stroke. Patients taking any of the COX-2 inhibitors should review their drug treatment with their doctors.
Electrical stimulation, including transcutaneous electrical stimulation (TENS), implanted electric nerve stimulation, and deep brain or spinal cord stimulation, is the modern-day extension of age-old practices in which the nerves of muscles are subjected to a variety of stimuli, including heat or massage. Electrical stimulation, no matter what form, involves a major surgical procedure and is not for everyone, nor is it 100 percent effective. The following techniques each require specialized equipment and personnel trained in the specific procedure being used:
TENS uses tiny electrical pulses, delivered through the skin to nerve fibers, to cause changes in muscles, such as numbness or contractions. This in turn produces temporary pain relief. There is also evidence that TENS can activate subsets of peripheral nerve fibers that can block pain transmission at the spinal cord level, in much the same way that shaking your hand can reduce pain. Peripheral nerve stimulation uses electrodes placed surgically on a carefully selected area of the body. The patient is then able to deliver an electrical current as needed to the affected area, using an antenna and transmitter. Spinal cord stimulation uses electrodes surgically inserted within the epidural space of the spinal cord. The patient is able to deliver a pulse of electricity to the spinal cord using a small box-like receiver and an antenna taped to the skin. Deep brain or intracerebral stimulation is considered an extreme treatment and involves surgical stimulation of the brain, usually the thalamus. It is used for a limited number of conditions, including severe pain, central pain syndrome, cancer pain, phantom limb pain, and other neuropathic pains.
Exercise has come to be a prescribed part of some doctors' treatment regimes for patients with pain. Because there is a known link between many types of chronic pain and tense, weak muscles, exercise-even light to moderate exercise such as walking or swimming-can contribute to an overall sense of well-being by improving blood and oxygen flow to muscles. Just as we know that stress contributes to pain, we also know that exercise, sleep, and relaxation can all help reduce stress, thereby helping to alleviate pain. Exercise has been proven to help many people with low back pain. It is important, however, that patients carefully follow the routine laid out by their physicians.
Hypnosis, first approved for medical use by the American Medical Association in 1958, continues to grow in popularity, especially as an adjunct to pain medication. In general, hypnosis is used to control physical function or response, that is, the amount of pain an individual can withstand. How hypnosis works is not fully understood. Some believe that hypnosis delivers the patient into a trance-like state, while others feel that the individual is simply better able to concentrate and relax or is more responsive to suggestion. Hypnosis may result in relief of pain by acting on chemicals in the nervous system, slowing impulses. Whether and how hypnosis works involves greater insight-and research-into the mechanisms underlying human consciousness.
Ibuprofen is a member of the aspirin family of analgesics, the so-called nonsteroidal anti-inflammatory drugs (see below). It is sold over the counter and also comes in prescription-strength preparations.
Low-power lasers have been used occasionally by some physical therapists as a treatment for pain, but like many other treatments, this method is not without controversy.
Magnets are increasingly popular with athletes who swear by their effectiveness for the control of sports-related pain and other painful conditions. Usually worn as a collar or wristwatch, the use of magnets as a treatment dates back to the ancient Egyptians and Greeks. While it is often dismissed as quackery and pseudoscience by skeptics, proponents offer the theory that magnets may effect changes in cells or body chemistry, thus producing pain relief.
Narcotics (see Opioids, below).
Nerve blocks employ the use of drugs, chemical agents, or surgical techniques to interrupt the relay of pain messages between specific areas of the body and the brain. There are many different names for the procedure, depending on the technique or agent used. Types of surgical nerve blocks include neurectomy; spinal dorsal, cranial, and trigeminal rhizotomy; and sympathectomy, also called sympathetic blockade (see Nerve Blocks in the Appendix).
Nonsteroidal anti-inflammatory drugs (NSAIDs) (including aspirin and ibuprofen) are widely prescribed and sometimes called non-narcotic or non-opioid analgesics. They work by reducing inflammatory responses in tissues. Many of these drugs irritate the stomach and for that reason are usually taken with food. Although acetaminophen may have some anti-inflammatory effects, it is generally distinguished from the traditional NSAIDs.
Opioids are derived from the poppy plant and are among the oldest drugs known to humankind. They include codeine and perhaps the most well-known narcotic of all, morphine. Morphine can be administered in a variety of forms, including a pump for patient self-administration. Opioids have a narcotic effect, that is, they induce sedation as well as pain relief, and some patients may become physically dependent upon them. For these reasons, patients given opioids should be monitored carefully; in some cases stimulants may be prescribed to counteract the sedative side effects. In addition to drowsiness, other common side effects include constipation, nausea, and vomiting.
Physical therapy and rehabilitation date back to the ancient practice of using physical techniques and methods, such as heat, cold, exercise, massage, and manipulation, in the treatment of certain conditions. These may be applied to increase function, control pain, and speed the patient toward full recovery.
Placebos offer some individuals pain relief although whether and how they have an effect is mysterious and somewhat controversial. Placebos are inactive substances, such as sugar pills, or harmless procedures, such as saline injections or sham surgeries, generally used in clinical studies as control factors to help determine the efficacy of active treatments. Although placebos have no direct effect on the underlying causes of pain, evidence from clinical studies suggests that many pain conditions such as migraine headache, back pain, post-surgical pain, rheumatoid arthritis, angina, and depression sometimes respond well to them. This positive response is known as the placebo effect, which is defined as the observable or measurable change that can occur in patients after administration of a placebo. Some experts believe the effect is psychological and that placebos work because the patients believe or expect them to work. Others say placebos relieve pain by stimulating the brain's own analgesics and setting the body's self-healing forces in motion. A third theory suggests that the act of taking placebos relieves stress and anxiety-which are known to aggravate some painful conditions-and, thus, cause the patients to feel better. Still, placebos are considered controversial because by definition they are inactive and have no actual curative value.
R.I.C.E. - Rest, Ice, Compression, and Elevation - are four components prescribed by many orthopedists, coaches, trainers, nurses, and other professionals for temporary muscle or joint conditions, such as sprains or strains. While many common orthopedic problems can be controlled with these four simple steps, especially when combined with over-the-counter pain relievers, more serious conditions may require surgery or physical therapy, including exercise, joint movement or manipulation, and stimulation of muscles.
Surgery, although not always an option, may be required to relieve pain, especially pain caused by back problems or serious musculoskeletal injuries. Surgery may take the form of a nerve block (see Nerve Blocks in the Appendix) or it may involve an operation to relieve pain from a ruptured disc. Surgical procedures for back problems include discectomy or, when microsurgical techniques are used, microdiscectomy, in which the entire disc is removed; laminectomy, a procedure in which a surgeon removes only a disc fragment, gaining access by entering through the arched portion of a vertebra; and spinal fusion, a procedure where the entire disc is removed and replaced with a bone graft. In a spinal fusion, the two vertebrae are then fused together. Although the operation can cause the spine to stiffen, resulting in lost flexibility, the procedure serves one critical purpose: protection of the spinal cord. Other operations for pain include rhizotomy, in which a nerve close to the spinal cord is cut, and cordotomy, where bundles of nerves within the spinal cord are severed. Cordotomy is generally used only for the pain of terminal cancer that does not respond to other therapies. Another operation for pain is the dorsal root entry zone operation, or DREZ, in which spinal neurons corresponding to the patient's pain are destroyed surgically. Because surgery can result in scar tissue formation that may cause additional problems, patients are well advised to seek a second opinion before proceeding. Occasionally, surgery is carried out with electrodes that selectively damage neurons in a targeted area of the brain. These procedures rarely result in long-term pain relief, but both physician and patient may decide that the surgical procedure will be effective enough that it justifies the expense and risk. In some cases, the results of an operation are remarkable. For example, many individuals suffering from trigeminal neuralgia who are not responsive to drug treatment have had great success with a procedure called microvascular decompression, in which tiny blood vessels are surgically separated from surrounding nerves. </s> |

Acute aortic syndrome most often happens because of a tear or damage to the inner wall of the aorta. This usually occurs in the chest (thoracic) part of the artery, but it may also occur in the abdominal part.
When a tear occurs, it creates two channels:
One in which blood continues to travel Another where blood stays still

It concludes bad lifestyle and cardiovascular diseases risk factors. Some you can change and some you can not change.
Risk factors you can change
Cigarette smoking: Cigarette somking has a close relationship with many cardiovascular diseases. Smokers' risk of developing coronary heart disease is 2–4 times than that of nonsmokers. Besides, it is also a powerful independent risk factor for sudden cardiac death in patients with coronary heart disease; smokers have about twice the risk of nonsmokers. Furthermore, cigarette smoking acts with other risk factors to greatly increase the hazard for coronary heart disease. People who smoke seem to have a higher risk of death from coronary heart diseases (and possibly stroke) but these risk isn't as great as cigarette nonsmokers'. High blood cholesterol: As blood cholesterol rises, so does risk of coronary heart disease. A person's cholesterol level is greatly affected by diet. Stress: Clinical researches demonstrate that stress may be a contributing factor for coronary artery disease. People under stress may overeat, start smoking or smoke more than they otherwise would. These behavior may increase the risk of incidence of cardiovascular diseases. Weight: Overweight and fat, especially body mass index (BMI) higher than 28 are risk factor for angina. Controlling weight is an available way to decrease the incident of angina. High blood pressure: Patients with Hypertension seem to have a higher risk to develope coronary artery disease. This is because that Hypertension decrease the reserve of coronary arteries. Diabetes mellitus: Like hypertension, patients with diabetes mellitus seem to have a higher risk to develope coronary artery disease. Because diabetes mellitus damage both coronary arteries and myocardial capillary vessels. Drinking too much alcohol: Data has demonstrated too much alcohol damage your arteries and myocardium.

Congenital antithrombin III deficiency is an inherited disease. It occurs when a person receives one abnormal copy of a gene from a parent with the disease.
The abnormal gene leads to low levels of antithrombin III. These low levels of antithrombin III can cause abnormal blood clots (thrombi) that may damage organs.
Often, patients with this condition will have a blood clot at a young age and will have a family member who has also experienced a blood clotting episode.

<s>[INST] What are causes Aortic coarctation? [/INST] The aorta carries blood from the heart to the vessels that supply the body with blood and nutrients. If part of the aorta is narrowed, it is hard for blood to pass through the artery. Aortic coarctation is more common in persons with certain genetic disorders, such as Turner syndrome. However, it can also be due to birth defects of the aortic valves. Aortic coarctation is one of the more common heart conditions that are present at birth (congenital heart conditions).

<s>[INST] What causes Aortic insufficiency? [/INST] Aortic insufficiency can result from any condition that keeps the aortic valve from closing all the way. A small amount of blood comes back each time the heart beats.
The condition causes widening (dilation) of the left lower chamber of the heart. Larger amounts of blood leave the heart with each squeeze or contraction. This leads to a strong and forceful pulse (bounding pulse). Over time, the heart becomes less able to pump blood to the body.
In the past, rheumatic fever was the main cause of aortic insufficiency. Now that antibiotics are used to treat rheumatic fever, other causes are more commonly seen.
