Travel agents or agencies must have an identifying number called an IATA, or International Air Transport Association, number to work with travel suppliers such as tour operators and airlines. Having IATA accreditation simplifies the business relationship between travel suppliers and travel agents.
Shunt (medical) In medicine, a shunt is a hole or a small passage which moves, or allows movement of, fluid from one part of the body to another. The term may describe either congenital or acquired shunts; and acquired shunts (sometimes referred to as iatrogenic shunts) may be either biological or mechanical.
A lumbar-peritoneal shunt is a piece of tubing inserted through a surgical procedure performed to relieve pressure in areas of the brain and spinal cord caused by a buildup of fluid applying pressure to the brain. This form of shunt is commonly used to treat intracranial hypertension and the resulting symptoms of vision loss and persistent headaches.
