University of Rochester researchers, however, made an important discovery about proteins that underlie and stimulate the disease, opening the door for a more targeted therapy in the future........ ]]> http://medicineworld.org/stories/lead/3-2011/tanning-bed-exposure-can-be-deadly.html http://medicineworld.org/stories/lead/3-2011/tanning-bed-exposure-can-be-deadly.html Thu, 21 Jul 2011 04:36:23 GMT Tanning bed exposure can produce more than some tanners may bargain for, particularly when they self-diagnose and use the radiation to treat skin eruptions, as per research conducted by the Indiana University School of Medicine Department of Dermatology. "There are a number of reasons to be cautious of tanning bed radiation but some people use tanning beds to 'self-treat' skin eruptions," said Jeffrey B. Travers, M.D., Ph.D., senior author of a study published online in the Archives of Dermatology "If the skin eruption is eczema or even psoriasis, a tanning bed might help. However, if the eruption is caused by a drug reaction then it can be dangerous"........ ]]> http://medicineworld.org/stories/lead/2-2011/relatives-of-melanoma-patients.html http://medicineworld.org/stories/lead/2-2011/relatives-of-melanoma-patients.html Thu, 21 Jul 2011 04:36:23 GMT It is well known that sunbathing increases the risk of skin cancer and that this risk is increased in people with a family history of melanoma. New research published in BioMed Central's open access journal BMC Public Health shows that young people in this 'at risk' group are still ignoring sun safety advice........ ]]> http://medicineworld.org/stories/lead/2-2011/careful-cleaning-of-childrens-skin.html http://medicineworld.org/stories/lead/2-2011/careful-cleaning-of-childrens-skin.html Thu, 21 Jul 2011 04:36:23 GMT When it comes to curing skin infected with the antibiotic-resistant bacterium MRSA (methicillin-resistant Staphylococcus aureus), timely and proper wound cleaning and draining appears to be more important than the choice of antibiotic, as per a new Johns Hopkins Children's Center study. The work is reported in the recent issue of Pediatrics....... ]]> http://medicineworld.org/stories/lead/2-2011/regrowing-hair.html http://medicineworld.org/stories/lead/2-2011/regrowing-hair.html Thu, 21 Jul 2011 04:36:23 GMT It has been long known that stress plays a part not just in the graying of hair but in hair loss as well. Over the years, numerous hair-restoration remedies have emerged, ranging from hucksters' "miracle solvents" to legitimate medications such as minoxidil. But even the best of these have shown limited effectiveness........ ]]> http://medicineworld.org/stories/lead/1-2011/follow-up-program-helps-detect-melanoma-earlier.html http://medicineworld.org/stories/lead/1-2011/follow-up-program-helps-detect-melanoma-earlier.html Thu, 21 Jul 2011 04:36:23 GMT A follow-up program for patients at high risk of developing skin cancer may be linked to the detection of melanomas at early stages and with good prognosis, as per a report posted online today that will appear in the May print issue of Archives of Dermatology, one of the JAMA/Archives journals........ ]]> http://medicineworld.org/stories/lead/1-2011/barriers-to-performing-skin-cancer-exams.html http://medicineworld.org/stories/lead/1-2011/barriers-to-performing-skin-cancer-exams.html Thu, 21 Jul 2011 04:36:23 GMT Time constraints, other illnesses and patient embarrassment may prevent dermatologists, internists and family practitioners from conducting full-body skin examinations, as per a report in the recent issue of Archives of Dermatology, one of the JAMA/Archives journals. However, dermatologists are significantly more likely than internists and family practitioners to conduct such screenings........ ]]> http://medicineworld.org/stories/lead/11-2010/melanoma-does-not-conform.html http://medicineworld.org/stories/lead/11-2010/melanoma-does-not-conform.html Thu, 21 Jul 2011 04:36:23 GMT Michigan scientists have determined that most types of melanoma cells can form cancerous tumors, providing new evidence that the deadliest form of skin cancer does not conform to the increasingly popular cancer stem cell model. In addition, the scientists observed that melanoma tumor cells can change their appearance by switching various genes on and off, making the cancerous cells a stealthy, shape-shifting target for scientists seeking new therapys, as per a team led by Sean Morrison, director of the U-M Center for Stem Cell Biology........ ]]> http://medicineworld.org/stories/lead/8-2010/earlier-detection-of-melanoma.html http://medicineworld.org/stories/lead/8-2010/earlier-detection-of-melanoma.html Thu, 21 Jul 2011 04:36:23 GMT Researchers are reporting development of a substance to enhance the visibility of skin cancer cells during scans with an advanced medical imaging system that combines ultrasound and light. The hybrid scanner could enable doctors to detect melanoma, the most serious form of skin cancer, in its earliest and most curable stages, the report in the monthly journal ACS Nano indicates........ ]]> http://medicineworld.org/stories/lead/7-2010/how-to-slow-growth-of-malignant-melanoma.html http://medicineworld.org/stories/lead/7-2010/how-to-slow-growth-of-malignant-melanoma.html Thu, 21 Jul 2011 04:36:23 GMT New Queen's University research has shown that the growth of melanoma, one of the most deadly forms of skin cancer, can be slowed when a little known gene called MicroRNA 193b is added. Victor Tron, head of pathology and molecular medicine, focused on miR-193b when he discovered that it was deficient in melanoma tumors and because there were very few studies done about the gene. The miRNA-193b gene is found in people's DNA and was unknown until 10 years ago........ ]]> http://medicineworld.org/stories/lead/6-2010/personalized-treatment-for-melanoma.html http://medicineworld.org/stories/lead/6-2010/personalized-treatment-for-melanoma.html Thu, 21 Jul 2011 04:36:23 GMT Identification of a key player in a signaling pathway involved in the development of melanoma the deadliest form of skin cancer may offer hope for new targeted melanoma therapies. Ann Richmond, Ph.D., and his colleagues at Vanderbilt-Ingram Cancer Center report that a signaling molecule, known as IKKand#946;, is essential for melanoma tumor development in a mouse model of the disease. The results, published June 7 in the Journal of Clinical Investigation, also point to ways of targeting therapies that inhibit IKKand#946; toward the patients most likely to benefit from them based on their genetic profile........ ]]> http://medicineworld.org/stories/lead/3-2010/acne-drug-prevents-hiv-breakout.html http://medicineworld.org/stories/lead/3-2010/acne-drug-prevents-hiv-breakout.html Thu, 21 Jul 2011 04:36:23 GMT Johns Hopkins researchers have observed that a safe and inexpensive antibiotic in use since the 1970s for treating acne effectively targets infected immune cells in which HIV, the virus that causes AIDS, lies dormant and prevents them from reactivating and replicating. The drug, minocycline, likely will improve on the current therapy regimens of HIV-infected patients if used in combination with a standard drug cocktail known as HAART (Highly Active Antiretroviral Therapy), as per research published now online and appearing in print April 15 in The Journal of Infectious Diseases. "The powerful advantage to using minocycline is that the virus appears less able to develop drug resistance because minocycline targets cellular pathways not viral proteins," says Janice Clements, Ph.D., Mary Wallace Stanton Professor of Faculty Affairs, vice dean for faculty, and professor of molecular and comparative pathobiology at the Johns Hopkins University School of Medicine........ ]]> http://medicineworld.org/stories/lead/1-2010/costs-of-psoriasis-treatment.html http://medicineworld.org/stories/lead/1-2010/costs-of-psoriasis-treatment.html Thu, 21 Jul 2011 04:36:23 GMT Findings from a cost model suggest that expenses for systemic psoriasis treatment appear to be increasing at a faster rate than inflation, and newer biologically derived therapys are more expensive than traditional systemic therapies, as per a report in the recent issue of Archives of Dermatology, one of the JAMA/Archives journals........ ]]> http://medicineworld.org/stories/lead/1-2010/how-melanoma-ivades-immune-system.html http://medicineworld.org/stories/lead/1-2010/how-melanoma-ivades-immune-system.html Thu, 21 Jul 2011 04:36:23 GMT Melanoma, if not detected in its early stages, transforms into a highly deadly, therapy-resistant cancer. Eventhough the immune system initially responds to melanoma and mounts anti-tumor attacks, these assaults are generally ineffective, allowing more advanced melanomas to win the battle and spread beyond the primary site. Now, scientists at Children's Hospital Boston and Brigham and Women's Hospital (BWH) shed light on how melanomas stimulate, yet ultimately evade, a patient's immune system. Their work, published online January 12 by the journal Cancer Research, also suggests ways drugs might block these tactics........ ]]> http://medicineworld.org/stories/lead/1-2010/celebrex-may-prevent-skin-cancers.html http://medicineworld.org/stories/lead/1-2010/celebrex-may-prevent-skin-cancers.html Thu, 21 Jul 2011 04:36:23 GMT A widely-available anti-inflammatory prescription drug can reduce the risk of a common skin cancer in humans, as per a researcher at Stanford's School of Medicine. Eventhough oral administration of the drug, celecoxib, is linked to an increased risk of heart attack and stroke in some people, it's possible that topical application could have a safer, protective effect for people prone to developing the cancers, called basal cell carcinomas, the researcher believes........ ]]>
