Medicine is both an area of knowledge (a science), and the application of that knowledge (by the medical profession and other health professionals such as nurses). The various specialized branches of the science of medicine correspond to the equally specialized medical professions dealing with particular organs or diseases. The science of medicine is the knowledge of body systems and diseases, while the profession of medicine refers to the social structure of the group of people formally trained to apply that knowledge to treat disease.
Medicine comprises various specialized sub-branches, such as cardiology, pulmonology, neurology, or other fields such as sports medicine, research or public health.
"Medicine" is also often used amongst medical professionals as shorthand for internal medicine. Veterinary medicine is the practice of health care in animal species other than human beings.
Vacutainer was developed in 1947 by Joseph Kleiner. The vein is first punctured with the hypodermic needle, which is connected to a translucent plastic holder. The needle actually has a second, smaller needle, and when a Vacutainer test tube is pushed down into the holder, its rubber cap is pierced. The vacuum in the tube sucks blood though the needle and fills itself. The tube is then removed and another can be inserted and filled the same way. It is important to remove the tube before withdrawing the needle, as there may still be some suction left, causing pain upon withdrawal. (More...)

- ...erythema infectiosum is the fifth disease of childhood, also known as slapped cheek syndrome, slap face or slapped face? It's caused by parvovirus B19, and usually follows a mild course.
- ...Reye's syndrome is a potentially fatal disease that causes detrimental effects mainly to the brain and liver? The cause of Reye's syndrome remains unknown; however, a link was found with the use of aspirin or other salicylates in children and adolescents who have a viral infection such as influenza, chicken pox or the common cold. The potentially increased risk of contracting Reye's syndrome is one of the main reasons that aspirin is not recommended for use in people under the age of 16.
- ...systemic lupus erythematosus (SLE or lupus) is a chronic, potentially debilitating or fatal autoimmune disease in which the immune system attacks the body’s cells and tissue, resulting in inflammation and tissue damage?
