What is latex Allergy?

herbalremedy | 26 July, 2008 05:26


Natural rubber latex comes from a liquid in tropical rubber trees. This liquid is processed to make many of the following rubber products used at home and at work:
·    Balloons
·    Rubber toys
·    Pacifiers and baby-bottle nipples
·    Rubber bands
·    Adhesive tape and bandages
·    Diapers and sanitary pads
·    Condoms

In addition, many medical and dental supplies contain latex, including gloves, urinary catheters, dental dams and material used to fill root canals, as well as tourniquets and equipment for resuscitation. Non-latex substitutes can be found for all of these latex-containing items.

Latex Allergy
Natural latex from the rubber tree Hevea brasiliensis is an allergen in persons with significant cumulative latex exposure, such as those in the health care and rubber industries, as well as those undergoing repeated surgeries, especially if they undergo surgeries early in life. Symptoms of latex allergy may progress rapidly and unpredictably to anaphylaxis. The prevalence of latex allergy has increased as the use of rubber gloves in health care settings has increased. Airborne latex particles that adhere to the cornstarch used to powder gloves are a significant cause of respiratory symptoms and a source of sensitization. Once an individual has become sensitized, he or she may experience allergic symptoms when exposed to any product containing latex.

Causes
In a latex allergy, your immune system identifies latex as a harmful substance. Your immune system triggers certain cells to produce immunoglobulin E (IgE) antibodies to fight the latex component (the allergen). The next time you come in contact with latex, the IgE antibodies sense it and signal your immune system to release histamine and other chemicals into your bloodstream.
These chemicals cause a range of allergic signs and symptoms. Histamine is partly responsible for most allergic responses, including runny nose, itchy eyes, dry throat, rashes and hives, nausea, diarrhea, labored breathing, and even anaphylactic shock.
 
Is latex allergy serious?
For most people, most of the time, the answer is no, latex allergy is not serious - they will only have mild symptoms (see 'symptoms').
However, latex allergy must still be taken very seriously because a few people do suffer a serious reaction known as anaphylaxis or anaphylactic shock, even to apparently harmless materials (2) (see 'symptoms').
Although anaphylaxis is a potentially life-threatening condition, there are ways of treating it and death as a result of latex allergy is extremely rare (see 'How can it be managed?').

How is latex allergy treated?

Avoidance of the provoking agent (allergen), such as latex, is the most effective way to manage any allergy. Latex free synthetic rubber, such as neoprene, nitrile, SBR, Butyl, and Vitron are polymers that are available as alternatives to natural rubber. There are no naturally occurring proteins in them and they are NOT responsible for latex allergy. Labeling is extremely important, but mandatory labeling is currently not required.

Patients who are known to be allergic should avoid any product that might contain latex until the latex content is determined by contacting the manufacturer. Even products labeled "safe latex" (which indicates lower proportions of natural latex) can cause latex allergy.

What is Pollens Alllergy?

herbalremedy | 26 July, 2008 05:21


Pollens are tiny egg-shaped powdery grains released from flowering plants, which are carried by the wind or insects, and serve to cross-pollinate other plants of the same type for reproductive purposes. When pollen is present in the air, it can land in a person’s eyes, nose, lungs and skin to set up an allergic reaction. Symptoms may include allergic rhinitis (hay fever), allergic conjunctivitis (eye allergies) and allergic asthma.

What causes it?
Hay fever is caused by breathing in pollen particles and by pollen getting into the eyes. You can get hay fever at any time from early spring to late summer, depending on which pollen or pollens you're allergic to.
The pollens most likely to cause problems in early spring are those from trees such as the silver birch, ash, oak and London plane.
Grasses pollinate during mid-summer from May to August. The most profusely pollinating grasses are timothy, rye, cocksfoot, meadow and fescue.
Occasionally, in late summer and autumn, weeds such as nettles and dock as well as mugwort and plantain can trigger hay fever.

WHAT IS POLLEN?
Plants produce the microscopic round or oval grains called pollen in order to reproduce. In some species, the plant uses the pollen from its own flowers to fertilize itself. Other types must be cross-pollinated; that is, in order for fertilization to take place and seeds to form, pollen must be transferred from the flower of one plant to that of another plant of the same species. Insects do this job for certain flowering plants, while other plants rely on wind transport.

The types of pollen that most commonly cause allergic reactions are produced by the plain-looking plants (trees, grasses, and weeds) that do not have showy flowers. These plants manufacture small, light, dry pollen granules that are custom-made for wind transport; for example, samples of ragweed pollen have been collected 400 miles out at sea and 2 miles high in the air. Because airborne pollen is carried for long distances, it does little good to rid an area of an offending plant - the pollen can drift in from many miles away.


Preventive Strategies:
    Avoid the outdoors between 5-10 AM. Save outside activities for late afternoon or after a heavy rain, when pollen levels are lower.
    Keep windows in your home and car closed to lower exposure to pollen. To keep cool, use air conditioners and avoid using window and attic fans.
    Be aware that pollen can also be transported indoors on people and pets.
    Dry your clothes in an automatic dryer rather than hanging them outside. Otherwise pollen can collect on clothing and be carried indoors.
Grazax (grass pollen allergen extract)

How does it work?

Grazax sublingual tablets contain a standardised extract of grass pollen allergen from Timothy grass (Phleum pratenase). The tablets are a type of medicine called immunotherapy. They are used to treat hayfever caused specifically by an allergy to grass pollen.

It is not fully understood how the medicine works. However, the grass pollen extract is thought to stimulate the body’s immune system to produce antibodies against grass pollen. These antibodies can then bind to any grass pollen that you encounter during the grass pollen season and prevent it from causing allergic symptoms.
