Rates of cancerous melanoma continue to increase, and early identification allows surgeons to treat the disease by removing the tumor, as per background information in the article. The disease is more common in individuals with a number of moles or other skin marks, particularly if the marks are atypical in color, shape or size. The challenge for clinicians who diagnose and treat pigmented skin lesions is to distinguish between cancerous melanoma and non-malignant simulants, the authors write........ ]]> http://medicineworld.org/cancer/lead/1-2008/multiple-skin-cancer-risk-behaviors-are-common.html http://medicineworld.org/cancer/lead/1-2008/multiple-skin-cancer-risk-behaviors-are-common.html Thu, 07 Feb 2008 03:03:32 GMT Whether youre basking on the beach during vacation, coasting down glittering white snow on a weekend ski trip, or simply walking the dog or running errands, sunlights ultraviolet rays can damage your skin year-round. Yet a new study by behavioral scientists at Fox Chase Cancer Center shows that most American adults engage in multiple behaviors that boost their risk of skin cancer by increasing their exposure to UV rays........ ]]> http://medicineworld.org/cancer/lead/12-2007/broccoli-against-devastating-genetic-skin-disorder.html http://medicineworld.org/cancer/lead/12-2007/broccoli-against-devastating-genetic-skin-disorder.html Thu, 07 Feb 2008 03:03:32 GMT The compound sulforaphane whose natural precursors are found at high levels in broccoli and other cruciferous vegetables has been hailed for its chemopreventive powers against cancer. Now sulforaphane has demonstrated new skills in treating a genetic skin blistering disorder called epidermolysis bullosa simplex (EBS), Pierre Coulombe and his colleagues at the Johns Hopkins University School of Medicine in Baltimore report at the American Society for Cell Biology 47th Annual Meeting........ ]]> http://medicineworld.org/cancer/lead/11-2007/mechanism-for-acne-drugs-link-to-depression.html http://medicineworld.org/cancer/lead/11-2007/mechanism-for-acne-drugs-link-to-depression.html Thu, 07 Feb 2008 03:03:32 GMT As per a research findings reported in the journal Experimental Biology and Medicine, researchers reveal a potential mechanism that might link the drug Roaccutane (Accutane in the US) to reported cases of depression in some patients taking the medication. The scientists had previously reported that the drug caused depressive behaviour in mice but, until now, the mechanism by which this might happen was unknown........ ]]> http://medicineworld.org/cancer/lead/10-2007/smoking-increases-risk-of-psoriasis.html http://medicineworld.org/cancer/lead/10-2007/smoking-increases-risk-of-psoriasis.html Thu, 07 Feb 2008 03:03:32 GMT Another disease can be added to the list of smoking-related disorders -- psoriasis. Scientists have observed that smoking increases the risk of developing psoriasis, heavier smoking increases the risk further, and the risk decreases only slowly after quitting. Investigators from the Massachusetts General Hospital, Brigham and Women's Hospital, the Harvard School of Public Health, all in Boston, USA, and Vancouver General Hospital, Vancouver, BC, Canada, have published the results in the November 2007 issue of The American Journal of Medicine........ ]]> http://medicineworld.org/cancer/lead/10-2007/using-honey-to-heal-wounds.html http://medicineworld.org/cancer/lead/10-2007/using-honey-to-heal-wounds.html Thu, 07 Feb 2008 03:03:32 GMT Surgeons are being advised to consider the supermarket as well as the drugs cupboard when it comes to effective wound healing, as per a research review reported in the recent issue of IJCP, the International Journal of Clinical Practice. And patients whove undergone surgery should ask their doctors whether they should apply honey to their wounds to speed up healing and reduce infection........ ]]> http://medicineworld.org/cancer/lead/9-2007/results-of-phase-1-metastatic-melanoma-study.html http://medicineworld.org/cancer/lead/9-2007/results-of-phase-1-metastatic-melanoma-study.html Thu, 07 Feb 2008 03:03:32 GMT Provectus Pharmaceuticals, Inc. announced preliminary results of its Phase 1 clinical trial of Provecta for the therapy of metastatic melanoma, the most aggressive form of skin cancer. Provecta demonstrated minimal side effects, significant efficacy and bystander effect on melanoma tumors in stage III patients.

Allergic contact dermatitis is caused by reaction to something that directly contacts the skin. A number of different substances (allergens) can cause allergic contact dermatitis. Commonly these substances cause no trouble for most people, but if the skin is sensitive or allergic to the substance, any exposure will produce a rash, which may become very severe. Allergic contact dermatitis affects about 5 percent of men and 11percent of women in industrialized countries and is one of the leading causes for occupational diseases........ ]]> http://medicineworld.org/cancer/lead/8-2007/green-tea-for-inflammatory-skin-diseases.html http://medicineworld.org/cancer/lead/8-2007/green-tea-for-inflammatory-skin-diseases.html Thu, 07 Feb 2008 03:03:32 GMT Green tea could hold promise as a new therapy for skin disorders such as psoriasis and dandruff, Medical College of Georgia scientists say. Scientists studied an animal model for inflammatory skin diseases, which are often characterized by patches of dry, red, flaky skin caused by the inflammation and overproduction of skin cells. Those treated with green tea showed slower growth of skin cells and the presence of a gene that regulates the cells' life cycles........ ]]> http://medicineworld.org/cancer/lead/7-2007/the-elderberry-way-to-perfect-skin.html http://medicineworld.org/cancer/lead/7-2007/the-elderberry-way-to-perfect-skin.html Thu, 07 Feb 2008 03:03:32 GMT Forget expensive moisturisers and cosmetic surgery, a compound found in the humble elderberry could give a natural boost to skin. In the first study of its kind, a team of scientists led by Prof Aedin Cassidy at the University of East Anglia and Dr Paul Kroon at the Institute of Food Research, will explore whether the skins condition is improved by a compound which gives berries their vibrant colour (called anthocyanin)........ ]]> http://medicineworld.org/cancer/lead/6-2007/natural-signal-holds-promise-for-psoriasis.html http://medicineworld.org/cancer/lead/6-2007/natural-signal-holds-promise-for-psoriasis.html Thu, 07 Feb 2008 03:03:32 GMT The body may hold a secret to normalizing skin cell growth that is over zealous in psoriasis and non-melanoma skin cancers and too slow in aging and sun-damaged skin, scientists say. Phosphatidylglycerol, a natural body lipid or fat, appears to signal cells to normalize growth and maturation or differentiation. "When we apply it to skin cells, we see the normalization ability," says Dr. Wendy B. Bollag, cell physiologist at the Medical College of Georgia........ ]]> http://medicineworld.org/cancer/lead/6-2007/sun-exposure-early-in-life-and-skin-cancer.html http://medicineworld.org/cancer/lead/6-2007/sun-exposure-early-in-life-and-skin-cancer.html Thu, 07 Feb 2008 03:03:32 GMT Skin cancers often contain different gene mutations, but just how these mutations contribute to the cause of melanomas has been a mystery. A new clue comes from researchers at the University of North Carolina at Chapel Hill Schools of Medicine and Public Health. Their research indicates that early life sun exposure, from birth to 20 years old, may specifically increase the risk of melanomas with BRAF gene mutations. A different mutation, on the NRAS gene, was found in patients who had sun exposure during the later part of life (between ages 50 to 60 years old). The results indicate that different subtypes of melanoma are linked to different risk factors........ ]]> http://medicineworld.org/cancer/lead/6-2007/diagnosing-skin-cancers-with-light-not-scalpels.html http://medicineworld.org/cancer/lead/6-2007/diagnosing-skin-cancers-with-light-not-scalpels.html Thu, 07 Feb 2008 03:03:32 GMT In an early step toward nonsurgical screening for cancerous skin cancers, Duke University chemists have demonstrated a laser-based system that can capture three-dimensional images of the chemical and structural changes under way beneath the surface of human skin. "The standard way physicians do a diagnosis now is to cut out a mole and look at a slice of it with a microscope," said Warren Warren, the James B. Duke Professor of chemistry, radiology and biomedical engineering, and director of Duke's new Center for Molecular and Biomedical Imaging. "What we're trying to do is find cancer signals they can get to without having to cut out the mole........ ]]> http://medicineworld.org/cancer/lead/5-2007/protects-skin-against-uvb-and-dehydration.html http://medicineworld.org/cancer/lead/5-2007/protects-skin-against-uvb-and-dehydration.html Thu, 07 Feb 2008 03:03:32 GMT Ultraviolet rays can be harmful to our skin and pave the way to the onset of skin cancers. VIB researchers connected to Ghent University have demonstrated that the caspase-14 protein - whose function has been unknown up to now - not only plays a role in maintaining the balance of moisture in the skin but also offers protection against UVB rays. Future strategies that increase the production of caspase-14 will open new possibilities for fortifying the skin as a barrier against all kinds of stress........ ]]>
