Anaphylaxis is a severe and potentially life-threatening reaction which happens when the body is exposed to a protein molecule that the immune system perceives as threatening. And the anaphylactic reaction can happen instantaneously or within minutes of exposure to a protein molecule which your body is hyper allergic to.
Some of the more common allergies which results in an anaphylactic reaction can be peanuts, these sayings, egg allergies and latex. The allergen, protein molecule which the body perceives as threatening, releases a severe attack mediated by the immune system. A flood of chemicals is released, the blood pressure drops, airways narrow, pulse quickens and many become nauseated and vomit.
Any evidence of an anaphylactic shock reaction necessitates an immediate trip to the emergency room. Individuals who have a previous history of a severe allergic response often carry epinephrine shots with them in case of an emergency. These shots will only support the body for a short period of time and give the individual enough time to get to the hospital. These are not a cure and will not the only treatment necessary during a severe allergic response.
Some other symptoms of an anaphylactic shock also include abdominal pain or cramping, anxiety, confusion, coughing, hives, nasal congestion and slurred speech. Some of the less common causes of an anaphylactic reaction includes food dependent exercise-induced anaphylaxis. During this a person eats a specific food and exercises within three to four hours after eating it thus triggering an immune response. Idiopathic anaphylaxis occurs without any apparent cause.
The exact number of individuals who suffer from anaphylaxis is unknown because not all reactions are reported in milder anaphylaxis may be attributed to asthma or a sudden episode of hives. In some cases a more serious and fatal episode could be attributed to a heart attack since the initial hives, swollen throat and asthma will fade quickly.
The exact causes of the anaphylaxis reaction within the body fall under two separate categories. The first is immunoglobulin E. mediated which is the truest form of anaphylaxis and requires an initial sensitizing exposure to an allergen. During this reaction mass cells release large amounts of histamine and other chemical mediators after re-exposure to the initial toxin.
Non-IGE mediated anaphylactic response are also called “anaphylactoid” reactions and are similar to anaphylaxis but do not require an immune mediated response. These are caused by direct stimulation of the mast cells in the same effects are produced. This type of reaction often occurs on an initial exposure because no offense at the station is required.
When consulting with your primary care physician or allergist they will also want to rule out other conditions that may possibly cause some of the same milder symptoms in anaphylaxis such as other conditions that cause flushing, blood sugar disorder, mastocytosis, panic attacks or heart or lung problems.
If you are with someone who is having this DeVere allergy attack quick reaction is essential. Call 911 or summon an ambulance as quickly as possible, ensure the person has a pulse and administer CPR as necessary and if they have an epinephrine autoinjector or any antihistamines give them right away.
Once they reach the hospital medical emergency personnel will administer more epinephrine to reduce the allergic response, oxygen to help compensate for restricted breathing, IV antihistamines and cortisone to reduce inflammation and steroid medications to prevent any prolonged symptoms. The autoinjector of epinephrine will only be enough to hold the person over until the get to the emergency room. While they may appear to have recovered well and have no visible signs or symptoms of allergic reaction once that epinephrine has been used it is essential that they make a trip to the emergency room for further evaluation.

The term eczema is applied very broadly to a group of persistant skin conditions that are characterized by dryness, recurring rashes, redness and, cracking, oozing and bleeding. Individuals who experience eczema may also have temporary skin discoloration which often disappear over time. They are a result of heeled lesions and scarring is very rare.
Interestingly, the prevalence of eczema will peak in infancy, meaning that the majority of individuals who are treated clinically start with their eczema when their infants. Girls are predominantly affected and also present during their reproductive years, between the ages of 15 and 49. Since The Second World War the number of individuals who are diagnosed with eczema has increased significantly. This is true both in the United States and in data collected in the UK.
There are at least four common types of eczema which have been reported- atopic eczema, contact dermatitis, xerotic eczema and seborrheic dermatitis. Much less commonly are diagnosed: Dyshidrosis, Discoid eczema, venous eczema, dermatitis herpetiformis, neurodermatitis, and autoeczematization.
By far atopic eczema is the most common and is linked to allergic disease believed to have a hereditary component. Sufferers often complain of in it she rash that is noticeable on the head, scalp, neck, inside of the elbows, behind the knees and on the buttocks. In contrast to psoriasis eczema is likely to be found on the flexor aspects of joints, meaning on the inside of where a joint bends.
Contact dermatitis has two different categories-allergic and irritant. It’s allergic contact dermatitis is the type of eczema that develops as a result of an allergen such as poison ivy. An irritant contact dermatitis will develop as a direct reaction to a detergent such as sodium laurel sulfate. Some substances cause a reaction once they touch the skin while others only cause a reaction after exposure to sunlight.
Doctors estimate that about three quarters of the time contact dermatitis or contact eczema is a results of an irritant and not an allergen. Different from atopic eczema, contact eczema is completely curable by removing the offending substance from the environment and in avoiding it all together.
In general, atopic eczema will come and go based on external factors like triggers are not always identified. The underlying condition appears to be an abnormal response in the body’s immune system to environmental stimuli. Like many diseases it cannot be cured but with current medical treatments it can be well managed.
Eczema can look different from person to person but it is characterized by a drying, read it she passed on the skin. In some cases it may bubble up and ooze while in others it may be more scaly and dry. Those who suffer from and chronically will find that the skin takes on a leathery texture because of the thickening caused by the eczema.
The National Institutes Of Health estimate that 15 million people in the United States alone have some form of eczema. About 10 to 20% of all infants born will develop some type of eczema by over half of these will improve greatly by the time they are five to 15 years old. Researchers have found a significant link in those who suffer from eczema as infants and go on to develop asthma as schoolagers.
Those who have eczema will want to moisturize frequently, avoid sweating or overheating, reduce stress levels, of weight using scratchy materials in their clothing, such as wool, avoid harsh soaps and detergents and, as much as possible, avoid environmental factors that trigger allergies such as pollen, mold and animal dander.
The goal in the treatment of eczema is to prevent scratching and long-term changes to the skin. The most common treatment is the application of lotions or creams as well as the prevention by identifying as many triggers as possible in avoiding them. Lotions and creams are most effective when applied within five minutes after getting out of the shower so that the moisture is locked in to the skin.
Individuals who have a current breakout may also find that cold compresses applied directly to the skin will help relieve the itching.
If the condition persists or even worsens physicians may recommend the application of nonprescription corticosteroid creams and ointments to help reduce the inflammation. These creams and ointments must be used for short periods of time because they can change the thickness of the skin, and actually thin it.
Alternatives include more potent prescription creams and ointments, which while are effective will have side effects. Your doctor will limit the length of time in locations where they can be applied.
Skin affected by eczema is at a higher risk for infection. Any infection must be treated immediately by your physician and not treated at home. For severe itching doctors may recommend antihistamines to decrease the histaminic response in the body and therefore the itching.
Two new topical medications, tacrolimus and pimecromlimus, have recently been approved by the FDA to treat atopic dermatitis. They belong to a class of drugs called calcineurin inhibitors which work by changing the immune response in the body. Thus far they have not produced some of the long-term side effects associated with long-term use of topical corticosteroids.
