Wound

A study of skin wound healing in 40 (human) volunteers has found that electrical stimulation significantly speeds up the healing process. The researchers hope to now develop and test dressings and devices that could be used in treatment of human or veterinary surgical wounds, sports injuries, and other serious skin trauma.

In the not-too-distant future, burn victims may be able to recover in the half the time than is possible today. If so, it will be thanks to a biodegradable dressing that applies cultured skin cells directly to the wound site. Read More
An experimental nanoparticle therapy cuts in half the time wounds take to heal compared to natural healing. The therapy has already been tested successfully in mice and will soon be tried on pigs, whose skin is similar to that of humans. If it reaches clinical use in humans, this sort of nanoparticle therapy could be used to speed healing of surgical incisions, chronic skin ulcers, and everyday cuts and burns and other wounds.

When you cut on your finger or scrape your knee, cells rush to the wound and repair or replace the damaged tissue. But how exactly this works – in particular how certain cells become "leaders" in the process – has long been a mystery. Now researchers at the University of Arizona (UA) have identified the mechanisms that cause and regulate this collective cell migration. Armed with this knowledge, biomedical engineers will be able to design new tissue regeneration treatments for diabetes and heart disease as well as for slowing or stopping the spread of cancer.

With uncontrolled bleeding the major cause of deaths on the battlefield, researchers at the University of Washington have developed an injectable polymer that could stem bleeding and provide extra time to get the injured to medical care. Called PolySTAT, the new polymer stems blood loss by strengthening blood clots. Read More
A fresh study carried out by researchers from King's College London (KCL) has established a link between a certain form of bacteria present on the skin following a surface wound and a type of white blood cell receptor, that together tip the scale away from the normal healing process and instead encourage the formation of cancerous tumors. The results of the study have the potential to create innovative treatment options for patients suffering from skin diseases, such as those that result in chronic ulcers and severe blistering.

When someone has diabetes, foot injuries such as ulcers can take a long time to heal. Not only does this cause diabetics prolonged discomfort, but it can even lead to amputation. Help may be on the way, however, in the form of a drug that's delivered through a skin patch. Read More
Because second- and third-degree burns damage underlying layers of skin, they can take a long time to heal. Such extended healing periods are not only painful to the patient, but increase the risk of infection and scarring. While various medications are available to deal with pain and infection, there is currently no commercial treatment to speed up the rate of healing of burn wounds. Now researchers have developed a nanogel that could fill this hole. Read More
Uncontrolled hemorrhage (bleeding out) is responsible for 80 percent of combat deaths. About the same proportion of those who die after being evacuated to a medical treatment facility also die of hemorrhage, usually associated with deep arterial wounds that cannot be treated using tourniquets – people die because we can't plug a simple hole. Now RevMedX, a small Oregon startup, has developed an alternative approach to treat such potentially survivable injuries. Read More
Venous ulcers are nasty things, often found on the lower extremities of elderly or inactive people. They occur when high blood pressure causes the skin adjacent to the affected veins to break down, leaving open wounds that take months or even years to heal. Standard treatments include compression bandages, infection control and standard wound dressings, although these approaches don’t work in all cases. Now, however, scientists are getting good results using band-aid-like patches that emit ultrasound into the ulcers. Read More
