Burns constitute one of the most serious and frequent problems that affect the skin. Typically, we think of a burn as an injury caused by fire or by contact of the skin with a hot surface. However, overexposure to ultraviolet light or contact of the skin with an electric current or a harmful chemical such as an acid can also cause burns.

The severity of a burn is determined by the depth of the injury, as well as by the amount of body surface area affected. The “rule of nines” is one of the most frequently used methods of determining the extent of a burn injury. With this technique the body is divided into 11 areas of 9% each . http://images.google.com/imgres?imgurl=http://www.nlm.nih.gov/medlineplus/ency/images/ency/fullsize/1078.jpg&imgrefurl= http://www.nlm.nih.gov/medlineplus/ency/imagepages/1078.htm&h=320&w=400&sz=25&hl=en&start=2&um=1&tbnid=V7wGu5a TN8nxXM:&tbnh=99&tbnw=124&prev=/images%3Fq%3Dfirst%2Bdegree%2Bburns%26um%3D1%26hl%3Den%26safe%3Dactive %26client%3Dfirefox-a%26rls%3Dorg.mozilla:en-US:official%26sa%3DN
