Adult beachgoers participating in research study accurately report their sun habits
Adult beachgoers participating in a research study accurately report their sun habits, including sunscreen use and clothing worn on the beach, according to a report in the October issue of Archives of Dermatology, one of the JAMA/Archives journals. The skin cancer cutaneous melanoma has become much more common and deadly in the United States over the past few decades, according to background information in the article. To reduce the risk of developing skin cancer, physicians recommend limiting the amount of time spent in the sun; seeking shade, especially during the hours at which ultraviolet rays are strongest; applying sunscreen with a sun protection factor (SPF) of 15 or higher; and wearing protective clothing, such as a hat, shirt, pants and sunglasses. Research on skin cancer prevention generally depends on the honesty of study participants reporting their behaviors.

Psoriasis increases risk for heart attack
Adults with psoriasis, especially younger patients with severe psoriasis, appear to be at increased risk for a heart attack, according to a study in the October 11 issue of JAMA. Psoriasis is a common, chronic disease that affects about 2 percent to 3 percent of the adult population. It is associated with markers of systemic inflammation, such as increased C-reactive protein levels, which have been linked to the development of atherosclerosis and myocardial infarction (MI; heart attack), according to background information in the article. Several hospital-based studies have indicated that psoriasis is associated with a higher prevalence of cardiovascular diseases, including heart attack, but these studies did not control for major cardiovascular risk factors.

How do you use your sunscreen?
WHEN out in the sun, how often do you apply sunscreen? If it's anything less than once every 2 hours, you might be better off not using any in the first place.

Skin Cells Found to Use a Coordinate System to Deduct their Positional Identity
Global-positioning system aficionados know that it's possible to precisely define any location in the world with just three geographic coordinates: latitude, longitude and altitude. Now scientists at the Stanford University School of Medicine have discovered that specialized skin cells use a similar mapping system to identify where they belong in the body and how to act once they arrive. These cellular cornerstones direct embryonic patterning and wound healing by sending vital location cues to their neighbors, and may help in growing tissue for transplant or understanding metastatic cancer.

UV-A therapy more effective than narrowband UV-B therapy in chronic plaque psoriasis
UV-A therapy was found to be more effective than narrowband UV-B therapy in treating patients with chronic plaque psoriasis, according to an article in the July issue of Archives of Dermatology. It is unclear whether narrowband UV-B (NB-UVB) therapy is as effective as psoralen-UV-A (PUVA) therapy in treating psoriasis, according to background information in the article. PUVA therapy includes the combination of 8-methoxypsoralen medication (taken orally) and exposure to UV-A (long-wave) radiation. NB-UVB involves exposure to UV-B (short-wave) radiation and is thought to be safer than PUVA.

Distress due to eczema very worrying
Children with serious skin conditions feel their quality of life is impaired to the same extent as those with chronic illnesses such as epilepsy, renal disease and diabetes, according to research published in the July issue of British Journal of Dermatology.

Glucosamine can stop formation of new age spots
For many women, accumulated sun exposure has already permanently damaged their skin cells, causing them to overproduce pigment that shows up as unsightly dark splotches and uneven skin tone over time. But new research indicates that glucosamine - a compound best known for treating arthritis – can actually help stop the formation of new age spots, and help fade existing ones.

Low-dose Arsenic in drinking water increases risk of premalignant skin lesions
Millions of persons around the world are exposed to low doses of arsenic through drinking water. However, up until now estimates of the health effects associated with low-dose exposure had been based on research from high-dose levels. In a study of more than 11,000 people in Bangladesh, research conducted by Columbia University's Mailman School of Public Health clearly provides evidence that a population exposed to well water with arsenic concentrations of as little as 50 ug/l is at risk for skin lesions. The report also concludes that older, male, and thinner participants were more likely to be affected by arsenic exposure.

Atorvastatin may increase new blood vessel formation
Systemic sclerosis (SSc), also known as scleroderma, is an uncommon and confounding disease characterized by excessive fibrous tissue formation and vascular abnormalities. Primarily affecting the small arties, SSc decreases blood flow to the body's extremities. This can lead to Raynaud's phenomenon, a condition that causes the hands and feet to feel extremely cold and numb; ulcers on the fingers and toes; and gangrene. SSc can also restrict blood flow to internal organs, resulting in lung, kidney, and heart damage. While its cause and cure have yet to be found, SSc is generally viewed and treated as an autoimmune inflammatory disorder.

Ineffective skin barrier may trigger immune reaction, illness
A genetic finding by researchers at the National Institutes of Health provides new insight into the cause of a series of related, common and complex illnesses – including hay fever and asthma as well as the skin disorders eczema and psoriasis – and suggests a novel therapeutic approach. These illnesses are essentially inflammatory disorders of the tissues that separate the inside of the body from the outside world, such as the skin and the linings of the throat and lungs.

Recurrent melanoma may be more common than previously thought
Approximately 8 percent of patients with melanoma skin cancer may develop an additional melanoma within two years of their initial diagnosis, and those with atypical moles appear to be at higher risk, according to an article in the April issue of Archives of Dermatology, one of the JAMA/Archives journals.

Addictive effects of frequent tanning - Study
Frequent users of tanning beds may be getting more out of the experience than darker skin, according to researchers from Wake Forest University Baptist Medical Center. New evidence suggests that ultraviolet light has "feel-good" effects that may be similar to those of some addictive drugs.

Eczema Producing Gene Discovered
Experts on genetic skin disorders at the University of Dundee, with collaborators in Dublin, Glasgow, Seattle and Copenhagen, have discovered the gene that causes dry, scaly skin and predisposes individuals to atopic dermatitis (eczema). Some of these individuals also develop a form of asthma that occurs in association with eczema. This work has been published in two consecutive papers in the March and April editions of the top genetics journal, Nature Genetics.

Imiquimod cream reduces fine lines and wrinkles
Results from a new study show that Aldara (imiquimod) Cream, 5%, a topical skin cancer treatment, improved the structure and appearance of prematurely aged skin, including fine lines, wrinkles, dyspigmentations and texture. The findings, from researchers at S.K.I.N. Incorporated, a dermatology research facility, are presented as a poster this weekend at the 64th Annual Meeting of the American Academy of Dermatology in San Francisco.

A pool of undifferentiated melanocyte stem cells resides in the hair follicle
Few things about growing older are as inevitable and obvious as “going gray,” yet scientists have been unable to explain the precise cause of this usually unwelcome transformation.
In a report posted today on the Web site of the journal Science, researchers from Dana-Farber Cancer Institute and Children's Hospital Boston say they have found the cellular cause of graying hair while investigating the origins of malignant melanoma, the potentially deadly skin cancer
