This is a case report of vaporization of the characteristic disfiguring plaques of discoid lupus erythematosus (DLE) with the carbon dioxide laser. This patient had a dramatic clinical and cosmetic improvement. It is suggested that the altered but not vaporized cells that remained were responsible for the retardation of the disease process.
Laser physiology has shown that while wound healing is generally excellent after laser impaction, it nevertheless is delayed. It is thought that this factor may be important in the treatment of hypertrophic and keloid scars. These scars have been treated in a variety of ways with the laser, and the results, which have been good, are reported. A possible explanation of the complex mode of action has been given. It is thought that more work should be undertaken in this field.
The diagnosis of decompression sickness is made largely by history; there are few physical findings and no radiographic or laboratory tests to support the diagnosis. We present three cases of factitious decompression sickness in which patients fabricated an appropriate history and underwent compression therapy. Due to the potential severity of decompression sickness and the relative safety of compression therapy, the initiation of therapy must not be delayed in a case of decompression sickness. Once therapy is begun, investigation into the particulars of a suspicious case can be made.
