Dear Dr. Hansen: I lead a very active lifestyle and am constantly outdoors. How do I best take care of my eyes during outdoor activities?

Protect your eyes from the environment, not just the sun. There’s a high risk for injury with many outdoor sporting activities. It’s paramount that you have effective sunglasses to protect eyes from flying objects and from ultraviolet (UV) rays. Brand names and high price tags do not indicate the quality of the lens. You should go to your eye care practitioner for recommendations for a pair that protects the entire eye.

Babies and infants in strollers should wear eye protection as well. People who start protecting their eyes at a young age are less likely to have problems later in life.

Keep rewetting products with you at all times. Keeping your eyes lubricated helps keep them free of certain pathogens. You should never rinse your contact lenses with water. Use eyedrops to lubricate and rewet contact lenses. The Complete Revitalize Active Pack for soft lenses contains all you need to keep eyes comfortable and protected while you’re on the go-it contains a travel-size Complete MoisturePlus Multi-Purpose Solution and Blink-N-Clean Lens rewetting drops.

Dear Dr. Hansen: Can I swim while wearing contact lenses?

No. All water (tap water, pools, lakes, the ocean, etc.) contains all sorts of contamination. Hot tubs are the worst. It doesn’t matter if you open your eyes briefly-you could get an infection in a matter of a few seconds. The best way to protect your eyes while swimming is to remove your contact lenses and wear good athletic goggles.

Dear Dr. Hansen: What should I look for in a good pair of sunglasses?

Sunglasses provide protection from UV rays in sunlight. Exposed UV light may damage the cornea and retina; however, good sun lenses can reduce the harmful UV rays. You can see on the sunglasses’ label its level of protection from UVA and UVB rays. Poorly made sunglasses may also cause visual distortion. Unfortunately, distortion-free lenses cannot be checked over the counter. This distortion results in a reduction of optical clarity and may cause headaches. Buying the right pair of sunglasses gives you maximum protection, so visit your eye care practitioner for recommendations of a good pair.

Dear Dr. Hansen: How can I prevent dry eye?

Dry eye syndrome is very common. It causes a variety of symptoms, from irritation, burning and itching, to blurred vision. Though dry eyes cannot be cured, there are a number of steps that can be taken to treat them. Eat a proper, healthy diet with lots of fruits and vegetables and get good exercise. Take breaks from staring at your computer screen every 30 minutes. Blink at intervals of three to five seconds to move tears and lubricate the eye. If you wear contact lenses, use a moisturizing lens solution for optimum comfort such as Complete MoisturePlus Multi-Purpose Solution for soft lenses that soothes with artificial tear ingredients, which can make a difference in how your eyes feel.

Trying to conceive is a difficult process for many people. The reason is that there are many factors involved in conception. You cannot tell if you or your partner is infertile unless you visit a doctor. There are a number of medical tests that your doctor can perform to detect infertility. There are also methods and products that the doctor can prescribe to help in conceiving a child.

One procedure a doctor can perform is to test the cervical mucus. Cervical mucus plays an essential role in conception, as it enables the sperm to make it all the way to the egg. The sperm are unable to do this if there is little or no cervical mucus present. Another factor involving cervical mucus is that it could be too acidic. It is necessary for the mucus to be alkaline. If it is acidic, it will kill the sperm before they reach the egg.

When a doctor checks the cervical mucus, he/she will look at the whether it is clear or curdled. If it is curdled, there is little to no chance of conception. If the mucus is clear and somewhat sticky, chances of conception are good.

Before you start to think about the possibility that you or your partner might be infertile, make sure that you have been having unprotected (natural method) sex over a number of months, or up to a year. Conception can take a long time, even for couples who have no troubles with infertility. Often, a couple may have unprotected sex for 8 or 10 months before conception takes place.

Once you have given yourselves this waiting period, if conception still has not occurred, visit your doctor for what steps you should take next. Try not to worry – focus on the many tests and procedures available to help you and your partner become parents of a beautiful baby.

Alcohol is addictive. You will find many people who will argue with this statement, but alcohol fits all the definitions of a harmful and addictive drug;

1. You need to take more and more of it to get the same effect
2. Your body becomes physically dependent on alcohol.
3. People die from alcohol abuse

An alcoholic is someone who has become physically dependent on alcohol. Alcoholism is permanent, it can not be cured. An ex-alcoholic is simply one who has not had alcohol for a long time. If the “ex”-alcoholic has one drink they are hooked again and have to go through the whole drying out process again.

Alcoholism treatment centers allow the alcoholic to live in a supportive and alcohol free environment while giving up the drug. Psychological advice is available and group therapy sessions help many recovering alcoholics.

Alcoholics Anonymous are one group that holds support meetings for alcoholics. AA has groups in most towns and cities in most countries and many recovering alcoholics find the group sessions to be an essential part of STAYING a recovered alcoholic.

Given the toxic nature of alcohol, if the substance was discovered today, it would never be licensed as a drug or food. It is only the entrenched nature of the alcohol industry and the fact that so many jobs depend on it that make it politically unacceptable to ban alcohol. Does this sound similar to the excuses made by opium producing countries? Would there be pressure to legalize the opium if it was grown in USA, because of the jobs dependant on the crop?

Perhaps western governments need to grasp the nettle of alcohol before prosecuting the war on drugs abroad. Alcohol kills many more people on a daily basis than die of drug related crime or addiction.

Drug trafficking causes crime, as addicts try to get money to pay for their supply – Political issue

Alcohol abuse causes deaths of innocents by drunk drivers. Isn’t this a political issue, too?

In this article we’re going to focus on one of the most annoying types of allergies, especially to people who love to eat.

You go out to the local pizza parlor, order two slices with extra cheese, sit down at the booth with your pizza in one hand and coke in the other and chow down. A few hours later after you’ve arrived back home just in time to watch your favorite TV show, suddenly your stomach feels like it’s about to erupt like a volcano. You run like a madman to the bathroom just in time to experience what seems to be the complete emptying of your insides.

Welcome to the world of food allergies and intolerances.

In the case of the runs after eating a couple of slices of pizza most likely you’re lactose intolerant which is just one type of food allergy. Technically, you can be allergic to just about any kind of food but there are some that seem to be more common that others.

Before we go any further let’s define exactly what a food allergy is. Food allergies can be broken down into 2 categories. The first one is hypersensitivity. This is an adverse reaction of the immune system itself and is unrelated to any actual physical effect of the food or food additive. These reactions are caused by immunoglobulin E (IgE) antibodies.

The second category is food intolerance. This is actually caused by the food itself and is not a function of the immune system itself overreacting to the food or food additive. The symptoms of an intolerance may be very similar to those of an actual immune symptom reaction but the causes are quite different.

Of the two, actual immune system reactions are the more common, though it does appear that a trend to intolerances, such as lactose intolerance, is on the rise. What actually happens with food allergies is that people with allergies produce IgE antibodies to specific epitopes in the food allergen. These antibodies bind to IgE receptors on the mast cells of tissue that are on the skin, digestive tract and respiratory system. The exposure of these antigens causes the release of histamines. This ultimately results in mucus secretion and muscle contraction which then leads to a wide range of symptoms which can range from unpleasant to serious or even severe. How severe?

Allergic reactions to food can be fatal almost immediately following the ingestion of food. Probably one of the most prevalent and dangerous of these food allergies are people who are allergic to peanuts. Just recently, as of this writing, a girl died simply from kissing someone who had recently eaten peanuts. That is how dangerous these allergies can be.

Less severe reactions to food allergies are oropharyngeal pruritus, angioedema, stridor, cough, dyspnea, wheezing, and dysphonia.

Aside from peanuts, the most common foods that people are allergic to are tree nuts, and shellfish.

Unfortunately the best way to avoid food allergies is to have a food allergy test done and then to avoid the foods that show positive on the test.

Leukemia is a disease of the blood and bone marrow that occurs on the background of genetic predispositions to cancer. Leukemia affects the cellular process of maturation, causing the accumulation of immature blood cells in the spinal marrow and bloodstream. In some cases leukemia causes the incomplete cells to multiply very quickly, while in other cases the abnormal blood cells have prolonged periods of life and persist in different places inside the body. Incomplete blood cells can’t substitute for normal blood cells, as they can’t carry out their roles. The cells affected by leukemia are therefore incompatible with the organism and can cause serious damage.

Judging by the speed of development and the persistence of the disorder, there are two types of leukemia: acute leukemia and chronic leukemia. Judging by the types of stem cells affected by the disorder, leukemia can either be lymphocytic or myelogenous.

Acute leukemia is different from chronic leukemia by the levels that stem cells are able to reach in their development (stem cells that present anomalies still manage to partially develop and either resemble immature cells or complete, normal white blood cells).

Acute leukemia is a form of cancer that develops very rapidly. It is manifested through overpopulation of the blood with immature cells that are unable to fulfill the functions of normal blood cells. In the case of acute leukemia, the marrow is unable to produce normal quantities of red blood cells, white blood cells and platelets. Patients who suffer from leukemia also develop anemia, a deficiency of normal red blood cells. Also, a decreased number of white blood cells reduces the body’s ability of overcoming infections, while the lack of platelets facilitates inflammation and bleeding.

Chronic leukemia tends to develop slower than acute leukemia. In the case of chronic leukemia, the body is able to produce blood cells that are more mature than those produced in acute leukemia. Although these cells may appear incomplete, they can’t fulfill their roles inside the organism and tend to cluster at different levels of the body. They also have a longer period of life.

Chronic leukemia of lymphocytic form is known to affect a type of blood cell called B lymphocyte. The disease weakens the immune system, interferes in the normal activity of the spinal marrow and facilitates the access of harmful cells to body organs. Chronic lymphocytic leukemia first occurs at the levels of the bone marrow, but can quickly spread to different organs and tissue through the bloodstream.

The presence of chronic lymphocytic leukemia is usually revealed by blood tests and careful body examination. Although apparently some people may have no symptoms of the disease, other patients may experience fatigue, lack of concentration, poor balance, memory loss, deterioration of vision and hearing, vertigos, body weakness, joint and bone pains. Just like in other forms of the disease, chronic leukemia requires immediate specific treatment and therapy. The chances of fully overcoming the disease are considerably enhanced if it is discovered quickly.
