Temporary skins

Biomedical materials prepared from polysiloxane/PU IPNs have been studied, and it has been reported that these materials can be useful as steam-sterihzing medical tubing. The mechanical properties showed a very wide range. Silon-TSR temporary skin, which was composed with polysiloxane/PTFE IPNs, has been proposed for assisting bum healing. ...

Well-known products include wound dressing, temporary skin, and connective-tissue replacement (BioFill , Gengiflex ) [7]. Numerous groups are working on these applications and investigating the healing effect of this external BC material (Table 2). 

Tetrasulfur tetranitride is not toxic.4 Men working continuously with it for a year or more have shown neither acute, chronic, nor delayed symptoms, apart from temporary skin irritation in some cases (which may not be due to tetrasulfur tetranitride itself). The mode of hydrolysis does not suggest any particular toxic hazard.4... 

Complications after steroid injection are minimal but can occur.The patient can expect slight discomfort at the injection site and occasionally subcutaneous white (steroid) deposits in the treated area. Depigmentation of the eyelid at the injection site, especially in dark-skinned individuals, and temporary skin atrophy can also occur. Skin depigmentation can be minimized by using a transconjunctival rather than a transepidermal injection in persons of color. When depigmentation occurs, it is... 

This type of response to a foreign compound is often termed an allergic or hypersensitivity reaction. There are some such responses which seem to be non-immunologically mediated, but these are poorly understood. The response can be manifested in a variety of ways and various organ systems may be involved. The response might be a minor one such as the development of a temporary skin rash, or it may be fatal as in the case of anaphylactic shock. However, the underlying mechanisms and...

Biosynthetic Temporary Skin Substitute. A biosynthetic skin substitute is a useful treatment for partialthickness wounds, including skin tears, bums, and abrasions. After applying a gel to the surfece of the wound, a semipermeable membrane of biosynthetic skin is used to cover the wound for protection from infection. Before the development of biosynthetic skin grafts, a physician had to choose between an allograft, which uses cadaver skin, and a xenograft, which uses tissue from another species. Biosynthetic dressings have also been developed. The dressing called Hydrofiber contains ionic silver and has been shown to prevent the spread of bacteria.
