At its most pernicious, it can thicken and harden their skin, their blood vessels, and their internal organs before, in many cases, killing them. Geneticists now report a closer connection between a gene profile for the profibrotic pathway TGF-beta and a tendency in some scleroderma sufferers to develop lung problems.

Unfortunately, when someone becomes diabetic, chronic non-healing wounds often develop, most often in the legs and feet. These wounds can be uncomfortable and even life-threatening. There are many types of treatments. One of the most painless and successful is hyperbaric oxygen therapy (HBOT).

Skin lesions caused by heparin may indicate the presence of a life-threatening decrease in the number of platelets, a condition called "heparin-induced thrombocytopenia" or, in most cases, a self-limiting, allergic skin reaction. Wed, 30 Sep 2009 05:00:00 EDT http://www.sciencedaily.com/releases/2009/09/090928131013.htm http://www.sciencedaily.com/releases/2009/09/090921162144.htm Scientists expect a new mathematical model of chronic wound healing could replace intuition with clear guidance on how to test treatment strategies in tackling a major public-health problem. The researchers are the first to publish a mathematical model of an ischemic wound -- a chronic wound that heals slowly or is in danger of never healing because it is fed by an inadequate blood supply. Mon, 28 Sep 2009 14:00:00 EDT http://www.sciencedaily.com/releases/2009/09/090921162144.htm http://www.sciencedaily.com/releases/2009/09/090924101623.htm Researchers have identified a genetic mutation that accounts for a perplexing condition found in people with an inherited immunodeficiency. The disorder, called combined immunodeficiency, is characterized by a constellation of severe health problems, including persistent bacterial and viral skin infections, severe eczema, acute allergies and asthma and cancer. Mon, 28 Sep 2009 08:00:00 EDT http://www.sciencedaily.com/releases/2009/09/090924101623.htm http://www.sciencedaily.com/releases/2009/09/090927152828.htm Never mind facial masks and exfoliating scrubs, skin takes care of itself. Stem cells located within the skin actively generate differentiating cells that can ultimately form either the body surface or the hairs that emanate from it. In addition, these stem cells are able to replenish themselves, continually rejuvenating skin and hair. Now, researchers have identified two proteins that enable these skin stem cells to undertake this continuous process of self-renewal. Mon, 28 Sep 2009 02:00:00 EDT http://www.sciencedaily.com/releases/2009/09/090927152828.htm http://www.sciencedaily.com/releases/2009/09/090923163846.htm The Merkel cell polyomavirus is the only human polyomavirus known to be associated with a rare skin cancer, known as Merkel cell carcinoma, according to a new study.

Collectively they are known as acne, a very common skin condition that affects millions of adolescents. Now a Norwegian study has investigated the links between acne, diet and mental health issues in both males and females.

The findings shed light on the basic mechanisms involved not only in formation of skin, but also on skin cancer and other epithelial cancers. Mon, 14 Sep 2009 02:00:00 EDT http://www.sciencedaily.com/releases/2009/09/090913134028.htm http://www.sciencedaily.com/releases/2009/09/090909103013.htm Scientists are reporting a major improvement in their potential new treatment for facial wrinkles that could emerge as an alternative to Botox and cosmetic surgery. The noninvasive technique combines high-intensity light from light-emitting diodes (LEDs) and a lotion made of green tea extract. It works 10 times faster than a similar anti-wrinkle treatment that uses LEDs alone, the researchers say.

The team has shown in human volunteers that defective immunity in the skin is caused by an inability to mobilize essential defenses that would otherwise recognize threats and clear them before irreparable damage is done. This discovery could be important for preventing, managing or treating many age-related skin health problems.

In addition, cancers detected by dermatologists were thinner and more likely to be in situ (only on the outer layer of skin) than were cancers detected by patients.

Researchers tested the health properties of 21 plant and herb extracts. They discovered all of the plants tested had some potential benefits, but were intrigued to find white tea considerably outperformed all of them.

Researchers identified the virus in more than a third of 58 SCC patients and in 15 percent of their tumors. Virus found in tumor cells had a mutation that could enable it to integrate into the host cell DNA, suggesting that the virus might help cause some cases of SCC.

The ability of aloe vera tooth gel to do that successfully has been a point of contention for some dental professionals. The study compared the germ-fighting ability of a gel to two commercially popular toothpastes and revealed that the tooth gel was just as effective -- in some cases more effective -- as the commercial brands at controlling cavity-causing organisms.
