At Air America Radio, Dr. Demento opened a gate between the worlds, unleashing the dreaded Yog-Sothoth upon the listeners, before moving with glee to Dothan, Alabama. Al Franken attempted to follow Dr. Demento soon after, but only got as far as congress.
A contraindication is a specific situation in which a drug, procedure, or surgery should not be used because it may be harmful to the person. There are two types of contraindications: Relative contraindication means that caution should be used when two drugs or procedures are used together. (It is acceptable to do so if the benefits outweigh the risk.)
A contraindication may be absolute or relative. 1  An absolute contraindication is a situation which makes a particular treatment or procedure absolutely inadvisable. In children, for example, aspirin is almost always contraindicated because of the danger that aspirin will cause Reye syndrome.
