A case of deep burns, while diving The Lusitania.

We present the first documented case of severe burns, sustained by a diver as a result of auto-ignition of air-activated heat packs at high partial pressure of oxygen and high ambient pressure. Our patient was diving the shipwreck of The Lusitania off the south coast of Ireland. This is a significant wreck, lying 90 metres down on the seabed.

Biological fate and clinical implications of arginine metabolism in tissue healing.

Since its discovery in 1987, many biological roles (including wound healing) have been identified for nitric oxide (NO). The gas is produced by NO synthase using the dibasic amino acid L-arginine as a substrate. It has been established that a lack of dietary L-arginine delays experimental wound healing.

Vitamin E: patterns of understanding, use, and prescription by health professionals and students at a university teaching hospital.

Background: Vitamin E is a generic term used to describe the many derivatives of tocol and tocotrienol. It is the major lipid-soluble antioxidant in the skin and has been used as treatment for many skin conditions, including scarring. Studies have shown that vitamin E provides no benefit to the cosmetic outcome of scars.
