Guillain-Barré syndrome..You may be 1 of the victims!
What is it?
Guillain-Barré syndrome is a disorder in which the body'simmune system attacks part of theperipheral nervous system. The first symptoms of this disorder include varying degrees ofweakness or tingling sensations in the legs. In many instances the weakness and abnormal sensations spread to the arms and upper body. These symptoms can increase in intensity until certain muscles cannot be used at all and, when severe, the patient is almost totally paralyzed. In these cases the disorder is life threatening - potentially interfering with breathing and, at times, withblood pressure or heart rate - and is considered a medical emergency. Such a patient is often put on a respirator to assist with breathing and is watched closely for problems such as an abnormal heart beat, infections,blood clots, and high or low blood pressure. Most patients, however, recover from even the most severe cases of Guillain-Barré syndrome, although some continue to have a certain degree of weakness.
Guillain-Barré syndrome can affect anybody. It can strike at any age and both sexes are equally prone to the disorder. The syndrome is rare, however, afflicting only about one person in 100,000. Usually Guillain-Barré occurs a few days or weeks after the patient has had symptoms of a respiratory or gastrointestinal viral infection. Occasionally surgery or vaccinations will trigger the syndrome.
After the first clinical manifestations of the disease, the symptoms can progress over the course of hours, days, or weeks. Most people reach the stage of greatest weakness within the first 2 weeks after symptoms appear, and by the third week of the illness 90 percent of all patients are at their weakest.
Causes?
No one yet knows why Guillain-Barré - which is not contagious - strikes some people and not others. Nor does anyone know exactly what sets the disease in motion.
What scientists do know is that the body's immune system begins to attack the body itself, causing what is known as an autoimmune disease. Usually the cells of the immune system attack only foreign material and invading organisms. In Guillain-Barré syndrome, however, the immune system starts to destroy the myelin sheath that surrounds the axons of many peripheral nerves, or even the axons themselves (axons are long, thin extensions of the nerve cells; they carry nerve signals). The myelin sheath surrounding the axon speeds up the transmission of nerve signals and allows the transmission of signals over long distances.

Take care of your eyes!
Eyenstein says:
Now its time to learn about all the things you need to do to make sure that your eyes are always healthy and safe!What should I do if I get something in my eye?
If you get something in your eye, NEVER EVER rub your eyes! Eyes are sensitive and can be scratched easily. Always ask an adult to help you.

So you should never look into the sun, because its brightness will damage the light-sensitive part inside your eye called the retina.
