Allergy Testing - Explanation of The Different Methods

Allergy testing may be recommended by your physician for several reasons:

-Your medication is no longer alleviating your symptoms.

-You have experienced a severe reaction that requires knowing its exact cause.

-Your allergy symptoms are worsening over time.

-Simply want to know what allergens to avoid.

Allergy testing is a fairly basic procedure that is completed within the doctor's office, with almost immediate results. Most patients opt for one of three basic skin tests since they are faster, easier, more accurate and less expensive than a blood test to determine what allergens affect you the most.

The Skin Prick is the most common of all the allergy tests used. It involves dipping a set of 5-10 needles into a solution of individual allergens, then pressed into the skin (usually on the back) to see if any reactions occur. The entire test takes less than 20 minutes and is considered highly accurate. Once the solution has been allowed to seep under the skin, a physician will check the area for redness, bumps, hives, or any other type of allergic reaction. Since most patients will undergo as many as 100 of these pricks during the testing, some itchiness may occur at the affected sites, but can be alleviated after the test is done with a basic antihistamine or other prescription drug offered by the physician.

The skin prick test can be used to detect airborne allergens; food allergies and to determine what medications a patient may be allergic too before prescribing certain drugs. An intradermal test may be required if the skin prick test comes out negative to suspected allergens, yet symptoms continue. This test requires actually injecting a small amount of allergen serum into the skin to see if a reaction occurs. This is usually only done to verify a few allergies.

The skin patch is primarily used to determine a skin allergy called contact dermatitis. This test involved soaking a prepared patch in allergen solution, then placing it on the skin for 24-72 hours.

In the event a patient can not undergo any of the skin tests to determine allergies due to medications that may alter the findings or a severe case of eczema which would make it difficult to see any reaction form the testing, a radioallergosorbent (RAST) blood test may be ordered. Although is can detect allergies by measuring immunoglobin E and lgE levels produced in people with allergies and asthma, the RAST test is not as sensitive as the skin testing available and is reserved for patients who can not undergo skin testing or who has tested positive to too many foods that a more detailed test is required.

Being tested for allergies is fairly simple and very accurate, allowing both patients and their physicians to see exactly what allergens are causing distress in order to best treat the patients symptoms and sometimes even alleviating the need for ongoing medications.

Relief For Dry, Itchy Eczema May Come From Chinese Healing Herbs

If you deal with the itching and burning of eczema you know all too well how uncomfortable it is. However, a solution may be found in the form of Chinese healing herbs.

Three new studies, presented at the annual meeting of the American Academy of Allergy, Asthma & Immunology, suggest that traditional Chinese herbal treatments might be helpful for both children and adults.

Eczema is the name used for a broad range of skin inflammation (dermatitis) and can happen at any age, though its most common in infants. By three years old eczema will disappear in half of infants, the others are stuck with the troublesome condition for life.

Up to 20% of children and from 1-2% of adults are thought to have this very uncomfortable and sometimes embarrassing skin problem.

No one knows exactly what causes it, though an issue with the immune system could well be to blame... especially in the case of atopic dermatitis

A different form of eczema, known as contact dermatitis can be caused when the skin comes into contact with something in the environment like soap, clothing, detergent, cosmetics or jewelry (even sweat) that causes a reaction from the skin.

Eczema has also been known to flare because of changes in temperature or humidity, or even psychological stress.

When it comes to treatment, a doctor looks at the patient's age, overall health and type of eczema involved. Creams and ointments are often used to keep the skin hydrated, avoiding over bathing and making other lifestyle changes to stay away from triggers are also important to keeping this condition under control.

There are over the counter antihistamines that can be used to control the itch. Sometimes a short course of oral corticosteroids is used to manage an acute outbreak.

A pair of topical medications have been approved by the U.S. FDA: tacrolimus (Protopic) and pimecrolimus (Elidel). However, an FDA warning in 2005 about these drugs cited animal studies that linked them to some types of cancer. Because of this, your doctor will use these medications only as a second line therapy - after getting no response from other forms of treatment. Even if you are given these medications, you'll only take them for a short time.

Perhaps because of the need for relief not achieved from traditional treatments, as many as 30% of those with eczema have been prescribed traditional Chinese medication, though there are still questions about whether this non-western approach works, and is safe.

In an effort to address these concerns, researcher Julia Wisniewski, MD, of Mount Sinai Hospital in New York studied 14 children who had persistent eczema and were treated with traditional Chinese medicine between August 2006 and May 2008.

All the children drank Erka Shizheng Herbal Tea two times a day, soaked in an herbal bath for at least 20 minutes, and applied an herbal cream to their skin several times a day.

They also had acupuncture treatments. At the beginning of the study, more than half of the children had severe symptoms; after 8 months of this regime, most had mild symptoms. Participants also needed less medication (steroids, antibiotics and antihistamines) after only three months of being treated.

The herbal treatments were safe, and caused no abnormal liver or kidney function.

When it comes to adult eczema, a team of Japanese researchers found that grown ups can also benefit from traditional Chinese medicine.

This work involved 274 men and women who had dealt with eczema for an average of 12 years. About a third had symptoms that were classified as severe or very severe, with patches of chronically dry, itchy, inflamed skin over about ten percent of the body.

After three to four months of treatment with herbal remedies that had been selected and administered based on the subject's symptoms, 87% of the subjects were symptom free. Another 12% were very much improved. One patient in the study had mild abnormalities in liver function that resolved by stopping the herbal therapy.

The third study was conducted by a team of researchers from the University of Cincinnati who tried to find risk factors for developing childhood eczema by following 636 infants of parents with allergies.

By age 4, babies with parents who had eczema had double the risk of having the skin condition than did other infants. Babies who tested positive for egg allergies (a fairly well known link to eczema) at age 1, were four times more likely to have eczema at four years old.

Those who tested positive for cat allergies (and had a cat) at age 1, 2 or 3, were more than 13 times more likely to have eczema by age 4 than other children. Pollen was also shown to be a risk factor for eczema - children who tested positive for elm allergies at age 1, 2 or 3 had about three times the chance of having eczema by age four.

So if your little one has eczema and is around a cat (dogs seem to offer a protective effect) or you live in a wooded area, you may want to consider allergy testing.

In all areas, while more work is needed, these three studies offer encouraging results and suggest if you suffer with eczema, or know someone who does, then there may be answers for them in Chinese healing herbs or TCM.

Fifteen Tips to an Allergy Free Season

After dealing with vertigo for years and finally seeing an Ear, Nose and Throat doctor, I discovered my problem was mostly related to allergies. The rigorous tests the doctor performed included a balance test, an Electronystagmography, which is a test to look at voluntary and involuntary eye movements. It evaluates the acoustic nerve, which aids with hearing and balance. I also had the usual round of allergy testing.

My doctor didn't discover or uncover anything drastic, but now that I know vertigo is related to allergies, when the dizziness sets in, I break out my sinus and allergy medications. The bouts of vertigo have drastically reduced in number and severity.

Allergies affect most of us. Some deal with the runny nose, sneezes and watery eyes. While others of us experience the unsteadiness that vertigo brings. Whatever the symptom, following these tips will help us in our move towards an allergy free season.

To control pollens and molds avoid:

o Humidifiers -humidity promotes the growth of mold.
o Wall paper and carpets in bathrooms - mold can grow under them.
o Mowing the law

In your homes and automobiles:

o Ventilate bathrooms, basements and other dark, moist places where mold can grow.
o Use air conditioning: it removes excess air moisture, filters out pollen from the outside and provides good airflow and circulation throughout your home. Change filters monthly.
o Drive with the air conditioner on
o Keep house doors and windows shut during pollen season.

To control animal dander:

o When pets must be inside, don't let your pets sleep in the same room with you.
o Bathe pets and wash pet bedding at least once weekly to remove dander and collected pollens.
o Use a high-efficiency particulate air filter in the bedroom.

To avoid and/or control dust mites:

o Don't use ceiling fans, this stirs and spreads the dust.
o Dust and vacuum weekly
o Remove wall-to-wall carpeting in the bedroom.
o Cover mattresses and pillows with allergy-proof cases to stop the invisible dust mite allergens.
o Wash bedding in hot water each week to kill the microscopic mites.

Nootropic: Idebenone

Introduction

Just what is Idebenone? Those of you who have inquired into this compound will see that the internet is awash with all manner of bizarre and fascinating claims; a more advanced version of coq10 is a common claim, a more biologically available version of coq10 another - one site even purports (not a surprise since they sell just coq10) that idebenone is a synthetic, Indian chemical totally unrelated to coq10 and intrinsically dangerous. Confused? Smartnootropics to the rescue.

Mechanism

Idebenone is a short-chain quinone in comparison to coq10 a long chain quinone and as such possesses both superior bioavailability and a faster peak plasma concentration profile. Idebenone is a potent antioxidant which is currently being investigated for its therapeutic role in neuromuscular disorders and unlike coq10 has demonstrated an ability to renew cellular ATP levels in abnormal conditions through cytosolic-mitochondrial shuttling. Idebenone also increased learning and memory in mice studies and has been claimed to activate NGF in the human brain. Finally Idebenone has been shown to uprate the production of the life-extending enzyme: superoxide dismutase in specific cortical regions.

Uses

• May benefit neuromuscular disorders


• Improves memory and learning and may increase brain dopamine levels


• Has been indicated to accelerate the turn over of the neurotransmitter serotonin.


• Powerful antioxidant


• May improve age related mitochondrial decline


• Increases production of superoxide dismutase

Issues

At high doses idebenone has demonstrated an ability to cause cellular death via genomic DNA fragmentation, however the study dose would be near impossible to match in-vivo and lower doses exhibited no such toxicity. Idebenone has also been theorised to stimulate oxygen radical production in mitochondrial electron transport and some now label it a "pro-oxidant" capable of accelerating the aging process - it is unclear whether its antioxidant profile and production of superoxide dismutase are sufficient to counteract this process or whether an additional antioxidant (ALA) could sufficiently nullify idebenone's pro-oxidant capacity.

Dosage

Idebenone is well tolerated and doses range from a mere 70mg up to 200mg or greater. As always one should err on the side of caution and begin with an allergy test.

Experience

I cannot comment on Idebenone's antioxidant capacity. From a single 150mg dose daily for a week I experienced a noticeable increase in energy and positivity I would normally associate with an uprating of the neurotransmitter serotonin. No side effects were noted. Due to the possible pro-oxidant nature of this chemical I intend to suspend further testing until more research has been completed.

Our Modern Epidemic of Autism, ADHD and Behavioral Problems

The Secretary of Health and Human Services, Kathleen Sebelius, has made it official the CDC now reports that 1 in 100 children are autistic. A study conducted by the National Survey of Children's Health (NSCH) found a staggering 1 in 63 children were reported to be autistic and the rate climbed to 1 in 38 if the child was a boy! Even more frightening is that 1 in 6 infants have developmental delays. The rate of ADHD has now reached levels of 1 in 10 children; this can be easily verified by talking with most elementary school teachers. Why is this epidemic exploding within our modern society? More importantly what can be done that is safe and effective to help these children? It is vital that parents are provided an understanding of these disorders, what affects the health of their child's brain and metabolically what can be done to restore health.

One approach that is gaining ground is biomedical care for children with autism, ADHD, OCD and behavioral problems. Biomedical care for these disorders is a science-based, metabolic approach to treatment. Everyone is now agreed that psychotropic drugs do not treat the problem; they simply reduce or suppress some of the symptoms. It would seem that a better choice is to address the underlying metabolic issues and health problems in these disorders. The primary guiding principle then is simple: remove what is causing harm, and add what is missing!

Research is now demonstrating that children with these disorders often have an exaggerated response to specific foods, airborne allergens, toxic chemicals and metals in our environment. It is well documented that they often lack various nutrients, enzymes, anti-oxidants, and essential fatty acids, and that they require methylation support. The combination of these factors leads to or aggravates neuroimmune dysfunction causing low-grade inflammation in affected brain tissues. This state of oxidative stress and chronic inflammation in the brain causes the nerve cells to not communicate properly with one another. These disorders have aptly been called disconnection syndromes, one area the brain is not communicating well with other areas leading to symptoms in cognition, emotion and behavior.

A partial outline of possible biomedical care for a child with one of these disorders:

1st: Laboratory tests through blood, urine and stool are performed to rule out any frank pathology and provide vital clues on what road to take for real healing.

2nd:The diet is improved along with specific dietary restrictions. A primary dietary goal may be a casein and gluten-free diet, along with removal of sugar, preservatives, and food additives.

3rd: Specific laboratory IgG food allergy testing may be performed to identify other food allergies that could be leading to brain inflammation, and then remove these foods from the diet.

4th: It is vital to identify any problems with maldigestion, malabsorption, and dysbiosis through specific laboratory tests such as comprehensive stool analysis. Then improve GI function by overcoming any dysbiosis and leaky gut problems, a primary source for chronic inflammation in these disorders.

5th: At this point specific supportive nutrients for autism and ADHD are added, depending on what has been found on history, exam and clinical lab.

6th: Support methylation and sulfoxidation-sulfation inadequacies and other cellular detoxification pathways

7th: Chelation of heavy metals can have marked benefit once all other factors have been addressed.

Allergy Testing By Skin Prick - Simple, Painless - Quick Results

Allergy testing has been progressing for over 100 years. Doctors and scientists have a difficult job looking to find the root causes of those symptoms such as running nose and streaming eyes, among several others. One third of Britons (around 19 million people) develop allergy symptoms, and are looking for effective answers through allergy testing.

Treatments and vaccines for hay fever, asthma and food allergies have failed to live up to expectation despite the huge amount of money we spend on them, and sufferers are left wondering where all the money pumped into research over decades has gone.

A high percentage of doctors and researchers are baffled at certain causes of allergies in many patients. Some people do react to certain events that trigger a group of reactions in their system, while the exact same events might not have any effect on others whatsoever. The difficulty in pinpointing the exact reason why someone is allergic to a particular food, insect or even house is a very complicated situation.

Many doctors advise that 'blood allergy testing' has to be employed to find out which allergy you suffer from, which takes longer than skin prick tests - but is extremely accurate. With the sheer amount of complex allergies in society today, it is a difficult and slow process finding out their source. Those who suffer allergies may have to wait a few decades for allergists to come up with answers.

There are several methods of allergy testing that are effective, quick, and cheap, but don't expect any miracle cure - as you will only be given advice on altering your lifestyle. These tests look for 'Immunoglobulin E (IgE) antibodies' in the human system for allergens like pollen, common dust mites, indoor pollutants and pet dander. Variations of these tests like skin prick food intolerance testing are used to examine the complex subject of food allergies. Food allergy testing kits are said to be very accurate in their results, but it's surely better to seek advice from a doctor before you purchase one these kits.

Finding allergy testing centres in your area is straight forward. You can ask your own doctor or practice nurse if you are registered with a GP. A health visitor or school nurse can give you good advice about testing and effective Allergy Relief, or even your local family health service authority where you live. Failing that, just pop down to your local hospital reception or speak to a pharmacist.

Allergy testing kits are available to buy in chemists and on the web that will give you your results in a short period of time. Basic skin prick testing is painless and it's usually the first test advised by specialists when allergy symptoms are present. Taking antihistamines and various other medications like inhalers are prohibited for up to 1 week before the skin testing start day.

A very small droplet of allergen is placed on the skin inner forearm. Up to 30 allergens can be tested on the one arm, which is marked in various areas so the tester knows which allergen those results will come from. Using a specially designed very sharp lancet, the skin is lightly pierced at an angle of 90 degrees directly on top of the allergen drop. Simple, painless and quick diagnosis.

The main advantage of this type of testing is that results normally takes up to 25 minutes. A visible raised wheal and red flare activity on the skin means that the tester can effectively eliminate a realistic cause for allergic symptoms, or diagnose you as positive for an allergy.

Allergy Patch Testing

Another relatively easy way to test for allergies is 'patch testing', which is carried out to determine whether allergies are present through dermatitis (Eczema). Tiny droplets of allergen are spread in a 'Vaseline mixture' which is applied to small metallic discs. These discs are usually taped on the patients back area, and left there for a few days. The patient comes back to the specialist after 2 days for removal and inspection in case of swelling and redness.

After another 2 days, the back is thoroughly scanned for signs of skin reaction to the small amounts of allergens that were applied there earlier. 'Atopy Patch Tests' (APT) on the skin can also be implemented to find out if reactions to foods are present. They are usually used to identify other allergens such as metals, rubber/latex and certain beauty cosmetics. Please note there are several more allergy testing methods available today.

CPR Practice Tests to Help You With Emergency Preparedness Training Success

People who are trying to learn cardiopulmonary resuscitation or CPR are required to take and pass a course in order to be certified. The American Heart Association and the Red Cross are the organizations that usually offer certification courses. In these classes, students learn the required protocols and must pass written and skills tests in order to receive their certification. That's one reason CPR practice tests are made available.

When you are enrolled in first aid or CPR classes you receive clear concise instruction on how different procedures should be carried out properly in order to help a victim. The instructor will demonstrate the different components of CPR in a class and allow you to practice on manikins to improve your skills. You will be allowed to take CPR practice tests to be sure that you understand the information in written and practical form before taking the actual certification tests.

Upon successful completion of CPR training, you will receive a card to carry that shows you are CPR certified. The certification is good for one year at which time you must renew it. The reason for renewing annually is because if someone receives their certification, but never uses it, they may forget some of the important protocol that could do more damage than good. This particular certification is one that should be renewed to keep the information fresh in the minds of those that will be performing the tasks. The guidelines change as well for certain aspects of the CPR certification. The annual renewal makes it possible to keep everyone up to date with what is required in proper CPR techniques. The best study aids to prepare for the CPR certification are the CPR practice tests that are available. They are multiple choice and can help you learn how to answer the questions and what type of questions you will most likely be asked. Your certification depends on your wealth of knowledge in the area and how to use it.

Along with CPR training, you can acquire first aid and AED, or automated external defibrillator certification. All of these skills can go hand in hand in helping you help others. These can contribute to complete emergency situation preparedness. You never know what emergencies can crop up in a location or situation. Being certified and keeping up with your certification through classes, CPR practice tests, skills testing and continuous learning will make you a valuable resource to someone who is experiencing an emergency situation.
