The U.S. Food and Drug Administration has ruled that the oral contraceptive YAZ can also be used by women to control moderate acne, the Associated Press reported..
The decision means that YAZ, made by Bayer Schering Pharma AG, is the first oral contraceptive to be approved by the FDA for three distinct uses, the drug maker said in a statement released Monday.
Along with birth control and acne treatment, YAZ is also approved in the United States to treat the physical and emotional symptoms of premenstrual dysphoric disorder, the AP reported.

The U.S. Food and Drug Administration (FDA) has approved Radiesse, a cosmetic dermal filler, for the long-lasting correction of moderate to severe facial wrinkles and folds such as nasolabial folds.
Radiesse is composed of calcium hydroxylapatite microspheres in a water-based gel carrier. The product provides immediate improvement so a patient looks better the moment the product is injected. The calcium microsphere technology also enables the body to generate new collagen. Further, Radiesse provides physicians a high level of control, predictability and finesse for facial applications.
FDA approval of Radiesse for treatment of facial wrinkles and folds was based on the results of a clinical trial supporting Radiesse’s safety and effectiveness. In this study, conducted at four medical centers in the United States, 117 patients with nasolabial folds were treated with Radiesse on one side of the face and a control agent (Cosmoplast, a human collagen product) on the other. Results based on the ratings of three blinded evaluators showed that six months after treatment, Radiesse was more effective than the control on every comparative efficacy outcome (p<0.0001).
Key clinical findings include:
· 82 percent of nasolabial folds treated with Radiesse showed improvement after six months. This was significantly higher than the control, which showed improvement in only 27 percent of treated folds (p<0.0001).
· After six months, the fold treated with Radiesse was more improved in 79 percent of patients compared to the control-treated fold. The folds treated with the control rated more improved in only 5 percent of patients.
· The nasolabial folds treated with Radiesse required approximately half as much volume (1.22cc) than the folds treated with the control (2.35cc).
· Both products were safe and well tolerated, with no serious adverse events reported. In the 117 patients treated, Radiesse had zero granulomas and the same low rate of nodules as the control.
The U.S. Food and Drug Administration has approved a new treatment for moderate-to-severe frown lines, medically called nasolabial folds.
BioForm Medical issued a statement describing its Radiesse as a longer-lasting alternative to existing wrinkle fillers. The company said its calcium-based microsphere technology not only fills in facial folds and depressions, but also stimulates the body to produce collagen, the fibrous protein that gives the face its structure and fullness.
The drug was also newly approved to improve the appearance of people with AIDS-causing HIV who have significant facial fat loss (lipoatrophy), the San Mateo, Calif.-based company said.
Radiesse was first FDA approved in 2002 for use in facial reconstructive surgery.

Findings from a new study confirm that tea extracts applied to the skin promote the repair of damage from radiotherapy, and shed light on the mechanisms involved in the injury...
Murad's Lighten and Brighten Eye Treatment was the top pick for “Best Dermatologist Brand” in the annual Shape of Beauty Awards.
The bumps (papules) and pimples (pustules) of rosacea, a poorly-understood facial disorder affecting an estimated 14 million Americans, may be the result of an allergy-like reaction to environmental and emotional triggers, according to new study results presented at the National Rosacea Society (NRS) research workshop during the annual meeting of the Society for Investigative Dermatology and reported in Rosacea Review.
"We are very excited about these findings because they may provide the basis for improving the treatment and management of this condition," said Dr. Richard Gallo, chief of the division of dermatology at the University of California-San Diego and lead investigator of the NRS-funded study. "By defining the process leading to the inflammation, new medications might be developed to block these effects."
Dr. Gallo explained that when the normal immune system is faced with any of a broad range of potential dangers—such as sun exposure, emotional stress, heat and spicy foods, among many others—receptors recognize potential threats and protect the body by prompting the production of protective substances that isolate and neutralize any harmful effects. With rosacea, however, these protective substances turn the body on itself like overzealous guards, leading to inflammation.
Using advanced mass spectrometry technology to analyze the biochemical composition of proteins in rosacea patients, the researchers discovered an abnormality in the production of protective molecules known as cathelicidins, Dr. Gallo said. In normal patients, the cathelicidins are found in a form that is inactive and would not lead to bumps and pimples. In rosacea patients, the forms of cathelicidins are different and lead to skin inflammation. The cause of this abnormality in cathelicidins seems to be due to an equally important problem in rosacea—an overabundance of yet another substance, called kallikrein, which can spur dormant cathelicidins into action.
"It appears that the combination of these two substances at abnormally high levels is a double whammy for rosacea patients," Dr. Gallo noted.
The researchers recently completed the picture when they were able to demonstrate that this process is linked to the actual formation of rosacea signs and symptoms. The skin of mice injected with the cathelicidins found in rosacea patients showed a dramatic inflammatory response—including bumps and pimples—while mice injected with normal cathelicidins showed no inflammation, either visually or under a microscope.
"The next step is to test these findings in human subjects through various therapeutic interventions," Dr. Gallo said. "As we gain a thorough understanding in humans, we can look for new medications that block this process in order to treat or prevent the inflammation associated with rosacea."
Rosacea is a chronic disorder that primarily affects the cheeks, nose, chin or forehead, and is often characterized by flare-ups and remissions. It typically begins as a flushing or redness that comes and goes, and visible blood vessels may also appear. Inflammatory bumps and pimples often develop, and in severe cases, the nose may become swollen and enlarged from excess tissue.
In addition to long-term medical therapy to bring the condition under control and maintain remission, patients are advised to keep a diary to identify and avoid lifestyle and environmental factors that may affect their individual cases. Some of the most common rosacea triggers include sun exposure, emotional stress, hot or cold weather, wind, heavy exercise, alcohol, hot baths and spicy foods.

An antibiotic-resistant acne germ can spread among family members, Swedish researchers find.
The germ is Propionibacterium acnes. Skin colonized by P. acnes tends to erupt into the blotches and pustules of acne. Since the 1960s, doctors have fought P. acnes with antibiotics. The bug fought back. It's now common to find P. acnes strains resistant to several common antibiotics.
Doctors hoped that the only people carrying the drug-resistant acne bugs would be patients on long-term antibiotic therapy. That isn't the case, find Carl Eric Nord, MD, PhD, and colleagues at Karolinska Institute in Stockholm, Sweden.
Nord and colleagues took skin samples from 10 acne patients, all on antibiotic therapy, and from two close family contacts of each patient. Twelve healthy, acne-free volunteers -- who were not taking antibiotics and did not have family members with acne -- served as a comparison group.
Nord and colleagues found that nearly half of the family members carried drug-resistant acne bacteria on their skin. Genetic analysis showed that these family members carried the same strain of P. acnes as the acne patient among them.
The good news is that the family members fought off the drug-resistant germs -- but only after the acne patient in their family stopped using antibiotics.
On the other hand, you apparently can't avoid drug-resistant acne germs by avoiding people with acne. A third of the healthy comparison group also carried drug-resistant P. acnes on their skin.
Nord reported the findings at last week's 46th Interscience Conference on Antimicrobial Agents and Chemotherapy, held Sept. 27-30 in San Francisco.

Estheticians must familiarize themselves with the most recent nonsurgical techniques in order to better advise and retain clients.
Botox injections can help facial wounds heal with less scarring, a small study finds.
"This is the first medication found to minimize scarring," senior author Dr. David Sherris, professor and chair of the department of otolaryngology at the University at Buffalo, said in a prepared statement.
His team published the study in the August issue of Mayo Clinic Proceedings.
The study included 31 patients who suffered wounds to the forehead or had surgery to remove skin cancers from the forehead, an area that's particularly susceptible to scarring. The patients received either an injection of Botox or saline within 24 hours after wound closure.
Photographs were taken at the time the patients received the injections and again six months later. The photographs were reviewed by two facial plastic surgeons who weren't involved in the study. They rated the patients' wound healing on a scale of zero to 10, with 10 representing the best result. The two surgeons' scores were averaged to reach a final score for each patient.
The median scores for wounds injected with Botox were 8.9, compared to 7.1 for wounds injected with saline.
"The result is of substantial interest in the field of scar treatment. When a wound occurs, especially on the face, people are always worried about the scar. We can now try to improve scars with these injections," Sherris said.
The study was funded by a clinical research grant from the Mayo Clinic.
