▪ Rabies: a contagious viral disease transmitted from the bite of an infected animal. Animals that are known to pass the disease to humans are dogs, cats, bats, rats and raccoons. The virus is found within the saliva of an infected animal and any bite that breaks the skin will result in infection as the virus, although very slow to act, is very virulent within a host. However, the disease can only be transmitted in this way and casual transmission is impossible. Rabies slowly attacks nerve and brain cells, gradually destroying them and leading to seizures, dementia, paranoia, aggression and insensitivity to pain. Ironically, this makes animals with the disease far more aggressive than normal, and less likely to back down from a confrontation with other animals, making it more likely that they will pass the infection to other animals, and to humans.
▪ Radiation Therapy: Radiation therapy uses high level ionizing radiation (such as gamma rays or beta particles) to treat diseases that are susceptible to such radiation. The radiation can be produced artificially (as with a particle accelerator) or with the use of highly radioactive isotopes, such as Cobalt-60. It is almost exclusively used for patients with cancerous tumors that cannot be removed surgically or treated with chemotherapy.
▪ Rash: Any discoloration of the skin caused by inflammation. A rash can be caused by any one of a number of diseases, but in most cases indicates some irritation of the skin, such as that caused by an allergic reaction.
▪ Reflex: An automatic muscle response by a muscle that is generally under voluntary control to sensory input without the intervention of the brain. Typical reflex responses are the contraction of the upper thigh muscle when the kneecap is stimulated, the spreading of the toes when the sole of the foot is touched, or the blink response when anything is heading towards the eye.
▪ Respirator: Used to circulate breathable air into and out of the lungs when a patient is unable to do so on their own. They are commonly used in emergency rooms, intensive care units and operating rooms.
▪ Respiratory Arrest: Any condition where the patient cannot draw oxygen into their lungs. It can be due to a number of causes, from a blockage of the airways by foreign matter to paralysis of the diaphragm and chest muscles. Cardiac arrest is the inevitable result when a patient cannot draw in oxygen, although a patient can live for a few minutes if they cannot breathe due to the ability of the body to burn energy anaerobically.
