Liver Cancer

Your liver is the largest organ inside your body. It filters harmful substances from the blood, digests fats from food and stores the sugar that your body uses for energy. Primary liver cancer starts in the liver. Metastatic liver cancer starts somewhere else and spreads to your liver.

Risk factors for primary liver cancer include

* Having hepatitis
* Having cirrhosis, or scarring of liver
* Being male
* Low weight at birth

Symptoms can include a lump or pain on the right side of your abdomen and yellowing of the skin. However, you may not have symptoms and the cancer may not be found until it is advanced. This makes it harder to treat. Treatment options include surgery, radiation, chemotherapy or liver transplantation.

Heart Failure

Heart failure is a condition in which the heart can't pump enough blood throughout the body. Heart failure does not mean that your heart has stopped or is about to stop working. It means that your heart is not able to pump blood the way it should.

The weakening of the heart's pumping ability causes

* Blood and fluid to back up into the lungs
* The buildup of fluid in the feet, ankles and legs - called edema
* Tiredness and shortness of breath

The leading causes of heart failure are coronary artery disease, high blood pressure and diabetes.

Treatment includes treating the underlying cause of your heart failure, medicines, and heart transplantation if other treatments fail.

Heart failure is a serious condition. About 5 million people in the U.S. have heart failure. It contributes to 300,000 deaths each year.

Reactive Airway Disease (RAD)

Reactive Airway Disease (RAD) is a term proposed by S.M. Brooks and colleagues in 1985 to describe an asthma-like syndrome developing after a single exposure to high levels of an irritating vapor, fume, or smoke. In time, however, it has evolved to be mistakenly used as a synonym for asthma.

Current usage of the term in the medical community is to describe an asthma-like syndrome in infants that may later be confirmed to be asthma when they become old enough to participate in diagnostic tests such as the bronchial challenge test. It can also manifest in adults with exposure to high levels of Chlorine gas, creating symptoms like asthma. The severity of these symptoms can be mild to fatal, and can even create long term airway damage depending on the amount of exposure and the concentration of Chlorine.

Yushō disease

Yushō disease (literally oil disease) was a mass poisoning by PCBs which occurred in northern Kyūshū, Japan in 1968. In January 1968, rice bran oil produced by Kanemi Company in Kyushu started to become contaminated with polychlorinated biphenyls (PCBs) and polychlorinated dibenzofurans (PCDFs). The contaminated rice bran oil was then sold to poultry farmers for use as a feed supplement and to consumers for use in cooking. In February to March 1968, farmers started reporting that their poultry were dying due to apparent difficulty in breathing; altogether 400,000 birds died.

About 14,000 people who had consumed the contaminated rice oil were affected in Japan. Common symptoms included dermal and ocular lesions, irregular menstrual cycles and a lowered immune response.Other symptoms included fatigue, headache, cough, and unusual skin sores. Additionally, in children, there were reports of poor cognitive development.
