Hand, Foot & Mouth Disease

Hand, foot and mouth disease is a viral infection caused by a strain of Coxsackie virus. It causes a blister-like rash that, as the name implies, involves the hands, feet and mouth. (Hand, foot and mouth disease is different than foot-and-mouth disease, which is an infection of cattle, pigs, sheep, goats and deer and is caused by a different virus.). Symptoms of fever, poor appetite, runny nose and sore throat can appear three to five days after exposure. A blister-like rash on the hands, feet and in the mouth usually develops one to two days after the initial symptoms. [NYHealth]

Heart Attack

A heart attack (also known as a myocardial infarction) is the death of heart muscle from the sudden blockage of a coronary artery by a blood clot. Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen. Blockage of a coronary artery deprives the heart muscle of blood and oxygen, causing injury to the heart muscle. Injury to the heart muscle causes chest pain and pressure. If blood flow is not restored within 20 to 40 minutes, irreversible death of the heart muscle will begin to occur. Muscle continues to die for 6-8 hours at which time the heart attack usually is "complete." The dead heart muscle is replaced by scar tissue. [Medicinenet]

Heart Burn

The name of a slow, continued, or remittent fever, which generally accompanies the end of organic affections, and has been esteemed idiopathic, although it is probably always symptomatic. It is the fever of irritation and debility; and is characterized by progressive emaciation, frequent pulse, hot skin, especially of the palms of the hands and soles of the feet, and, towards the end, colliquative sweats and diarrhea. Being symptomatic, it can only be removed by getting rid of the original affection. This is generally difficult, and almost always hopeless in the disease which it most commonly accompanies, consumption. [Dunglison1868].
