 HPV Virus Human Papilloma Ciruses (HPV) is a virus that infects humans. Some of the effects of the virus are associated with sexually transmitted diseases (STD’s). Over one hundred strains of the virus have been identified by Scientists. Most of these strains are harmless. Some of these strains can produce common skin warts which appear on the hands and feet. Approximately thirty strains are spread through sexual contact. Some of these thirty can cause visible warts known as genital warts, while others can cause cervical and genital cancer. HPV greatly outnumbers other std’s making it the most common sexually transmitted infection. An estimated 80% of sexually active adults are infected with one or more genital HPV strains at some point in their life. The vast majority of infected people suffer no side effects from the virus, which means that most of these people don’t even know that they are infected. This lack of knowledge doesn’t stop them from infecting others though...

 Hyperactivity vs ADD – What’s The Difference? A common misconception, when it comes to Attention Deficit Disorder, is that it is one in the same with hyperactivity. However, this is far from the truth. While people with ADD may exhibit signs of hyperactivity, it is not an inherent trait of the disorder and often does not occur with sufferers of ADD. Hyperactivity is a general term referring to excessive and/or pathological activeness. This term is often used erroneously for an active person that does not meet the excessive criteria. It is important to understand that all children are active to a certain extent, and that some are even extremely active. However, this does not necessarily constitute hyperactivity. A hyperactive person will seem to be driven to movement, making it almost impossible to sit still. If sitting, they will often fidget or talk excessively as a countermeasure. Hyperactivity is often difficult to assess in adults; however, children are much easier to diagnose...

 I am Hepatitis C I am Hepatitis C a form of hepatitis liver inflammation that is caused by a virus known on the street as HCV. Before HCV was discovered in 1989, they used to refer to me as a related name to my little brothers, “non-A-non-B hepatitus”. A laughing stock of the virus world, but that all changed in 1989. Approximately 15 to 20 percent of people are able to deal with me and develop immunity. That doesn’t speak for the rest, and also 15 to 20 percent of them that will show acute signs of the me, Hepatitus C. It is known that for each 100 chronic Hepatitis C patients, 20 will develop liver cirrhosis. Liver cirrhosis is a nasty scarring of the liver, which can progress into Liver cancer. I have infected over 180 million people around the world, and am now responsible for the majority of liver transplants, Hepatocellular carcinoma and also the major cause of death among HIV co-infected patients. Most times, people that are carrier me in the chronic state, chronic hepatiti...

 I am a mouth ulcers Although it’s not my favorite thing to be in the world, I am a mouth ulcer. My street name is most commonly: canker sore. I’ve got a fancy name, and that involves painful open sores that will exist in your mouth when the mucous membrane breaks. You might also choose to call me one of these other names: aphthous stomatitis or aphthous ulcer. Now that we have that out of the way… I will often being with a tingling or burning sensation in your mouth. This ‘tingling’ or ‘burning’ will exist in the place where the future mouth ulcer, canker sore, aphthous stomatitis or aphthous ulcer will exist. It won’t take me longer than a few days to turn into the state of a red bump or spot inside your mouth, which will then be followed by an open ulcer. Once at the open ulcer state I will appear as a white or yellow oval with an inflamed red border. Modestly I will be approximately 3 mm wide, however, for quick bragging rights, I can reach up to and beyond 1 cm wide in extreme...

 I am Malaria I am Malaria, an infectious disease. Every year I kill approximately one point three million humans, and infect another 350-500 million. My work is mostly in the tropics where favorable climates and lifestyles aid in my process. Over 85% of deaths occur in Sub-Saharan Africa. Do I have your attention? Why I exist  – I exist because as a result of the protozoan parasite. My mode of transit between humans for transmission is by mosquitos. Mosquitos are favorable as they are vast and persistent in their work, as I am in mine. Although everyone is vulnerable to my attacks, it is pregnant women and infants under the age of five that I have the most success with. A french army doctor names Charles Louis Alphonse Laveran first discovered me, and was awarded the Nobel prize for Physiology in 1907. (I am still waiting for my turn to win the award). It was Alphonse, Charles that was the first person to be able to describe my life cycle, as I develop in the bodies of mosqui...

 I am Motor Neurone I am Motor neurone disease, you might also know me as progressive muscular atrophy, or progressive bulbar palsy, or and primary lateral sclerosis, or Lou Gehrig’s disease; All the while I just prefer being called MND for short. All these fancy names and all you want to know is if you have me or not. Read on. Usually I, motor neurone disease, exist in those individuals that are between the ages of 40-70, with my average being a respectable 55. Don’t get excited quickly thinking that I only attack those over 40 and under 70 years of age, as I have cases that range from 18 to over 100. Primarily I am characterized by “The progressive loss of voluntary muscle contraction due to the destruction of nerve cells in the brain and the spinal cord that are responsible for the stimulation of the voluntary muscles.” Although my initial symptoms can be sneaky and a little under the table (subtle), I will down the road cause progressive physical disability. I am found easily b...

 IBD And Crohn’s Disease – What’s The Link? Inflammatory Bowel Disease (IBD) is a term used for a group of illnesses affecting the digestive system. With roughly one million sufferers in the United States, IBD is primarily composed of two disorders: Crohns Disease and ulcerative colitis. What takes place with IBD, Crohns, and ulcerative colitis is the bodys immune system has an exaggerated response to an unknown bacteria or condition of the bowel system, releases a large number of white blood cells to the affected area, and as a result, the area becomes drastically inflamed. This swelling causes ulcerations and injury to the bowel, as well as various other negative side effects. Although extensive research has been done, it is unclear what causes the excessive immune response in IBD. Some believe it is the bodys mistaken identification of good bacteria in the bowel as being dangerous, while others believe it is a foreign agent that triggers the immune system, which in turn, does no...
