Talk About Allergies…
Avoidance of allergic triggers minimizing exposure will prevent exacerbation of symptoms. Below are strategies to eliminate or avoid what you are allergic to. High efficiency particulate air (HEPA) filters remove very small particles, mold spores and pollen fragments. These units are used near desks for filtration of smoke and dust. Face masks provide protect against certain allergens. Avoid cooling systems that pull in air from outside should be avoided.

Pollen from trees, grasses and weeds can vary depending on geographic area and season.
- Keep bedroom and car windows closed and air conditioner.
- The afternoon pollen concentration is lower than morning
- Remove trees or shrubs that are allergens from around your bedroom window,

Mold spore and fungi sources are found in many common areas and include indoor plant dirt, leaves, cut grass, composite piles, wooded areas, shower curtains, sleeping bags, window frames, crawl spaces, bathrooms, basements. Techniques to minimize growth:
- chlorine bleach
- using a dehumidifier
- adequate ventilation

An air filtration device and a humidity level of less than 40% are important for dust elimination.. Plain wood or plastic are good alternatives to carpets, upholstered furniture and drapes. Tips to avoid house dust and mites:
- clean floors with a damp mop daily
- wash area rugs and bedding frequently
- damp dust daily using a face mask

Feathers, dander and saliva are epidermals and to minimize exposure use the following tips:
- remove household pets from your sleeping area
- wash your hands after touching the pet
- vacuum frequently with an exhaust filter

Always consult a professional exterminator first before using pesticides around your home. Avoid garbage cans around your home or near restaurant kitchens. Do not tamper with beehives or wasp or hornet nests. Strategies to follow when outdoors:
- wear protective clothing and shoes
- wear dark colors instead of bright colors
- avoid using strong scents

Magnetic resonance imaging (MRI) is a non-invasive method used to render images of the inside of an object. It is primarily used in medical imaging to demonstrate pathological or other physiological alterations of living tissues.

***An Abnormal MRI Doesn't Always Mean Knee Damage
When an athlete injures his knee, doctors usually order a special test called an MRI (magnetic resonance imaging), to determine if the cartilage is broken. A recent study in the American Journal of Sports Medicine (November-December 1994) shows that MRI's often indicate broken cartilage even when the knee is normal. Up to 24% of MRI's will show signs of cartilage damage in normal knees.
The ends of bones are protected by a thick, tough white gristle called cartilage. Once an athlete breaks the cartilage in his knee, it will never heal and often will continue to break with heavy physical exercise. Doctors can remove lose pieces of cartilage, but they cannot operate to replace the lost cartilage. The cartilages in the knee fit together like gears in your car. When cartilage of the lower leg extends upward, cartilage in the upper leg extends downward. When you break cartilage, the fit is less perfect and a hard force on the joint can cause further breakage of cartilage. Therefore, people who break cartilage in their knees are usually cautioned to avoid hard exercises that may continue to break cartilage in the knee and eventually require a knee replacement.
If your knee is swollen from an injury, you probably have cartilaginous damage and should avoid hard trauma to your knee for the rest of your life. If your knee hurts but is not swollen, your doctor may order an MRI, but an abnormal MRI does not necessarily mean that you have broken the cartilage in your knee.

***Talk About Research…
Research studies evaluate a new treatment. When a new treatment becomes available, it goes through rigorous testing in a laboratory and then in a clinical setting. The testing is carefully monitored, and the results are evaluated and published.There are three types of clinical trials. Each of these trials is a carefully controlled test for a new drug or procedure.
Phase I trials determine the best way to provide a new treatment and how much can be given safely. These trials involve cancer patients with advanced disease who have tried every possible treatment with no long-term success. These patients are willing to undergo treatments that probably will not cure their cancer but that give them some hope and that might help a cancer patient in the future. Any treatment given these patients has first undergone testing on animals and has been approved for human trials.
Phase II trials study the effect of a new treatment on patients whose cancer has not been cured by standard treatments. There is some possibility that the treatment may benefit these patients. A treatment reaching phase II trials has gone through phase I trials.
Phase III trials compare a new treatment to current treatments. These trials require large numbers of patients to control the effects that age, race, gender, and other factors may have on the experimental treatment. One group of patients receives the experimental treatment, and another is given a standard treatment. Randomization (selection by chance to be in one group or the other) is used to keep bias out of the trial.
