Controversies about the decubitus ulcer.

Knowledge of the decubitus ulcer has made great progress in recent decades. No longer is the diagnosis of a bedsore, as it was in the iron lung days, almost a death warrant. One cannot cause to heal a patient who is in organ failure, nor can one necessarily prevent ulcers in a new spinal cord-injured patient. Reflecting on the common cold, one realizes that prevention is limited to covering the face when sneezing, and treatment is symptomatic. There is no way of eradicating the virus of the common cold, nor is there an appropriate treatment. The decubitus ulcer should be conceived of in a similar vein, until understanding is more complete and specific treatments are available.
