Medical scientists reported significant progress in uncovering the potential causes and other key aspects of rosacea during the National Rosacea Society's third annual research workshop, held in conjunction with the annual meeting of the Society for Investigative Dermatology. More than 130 researchers heard results of ongoing studies funded by the National Rosacea Society, and discussed the need for further scientific investigation into this highly prevalent disorder.

Sun exposure appears to trigger a substance in the body that may lead to the visible blood vessels that often appear with rosacea, according to research funded by the National Rosacea Society and reported at the annual meeting of the Society for Investigative Dermatology.

"Our initial study showed that sunlight may indeed have a role in causing rosacea," said Dr. Marita Kosmadaki, research fellow, Department of Dermatology, Boston University, who presented results of her research with Dr. Mina Yaar, professor of dermatology at Boston University.

Some individuals may be genetically predisposed to develop rosacea, according to results of a study to determine whether rosacea patients had a family history of the disorder and whether they came from a particular ancestral community of origin. The results were reported in a poster presentation by Dr. Wayne Guliver, chairman of dermatology, and other researchers at Memorial University of Newfoundland during the annual meeting of the American Academy of Dermatology. ¹

High blood pressure may occur more frequently in rosacea patients, according to a recent study by Dr. Aditya Gupta, associate professor, Department of Medicine at the University of Toronto, presented at the annual meeting of the American Academy of Dermatology.

The National Rosacea Society announced that four new studies of rosacea have been selected for funding as part of its research grants program to encourage and support the advancement of scientific knowledge of this widespread but poorly understood facial disorder.

"We are pleased that the number of grant applications has continued to increase since the awarding of the first grants from this important new program last year," said Dr. Jonathan Wilkin, chairman of the Society's medical advisory board, which reviewed and selected the grant applications for funding.

A recent study suggested that treatment of Helicobacter pylori, a bacterium associated with peptic ulcers and other gastric disorders, may benefit the often small portion of rosacea patients who harbor this infection. However, another study has found that H. pylori itself does not appear to be a major factor.

Medical scientists reported significant progress in exploring the potential causes and other key aspects of rosacea during a recent research workshop organized by the National Rosacea Society.

The session was attended by more than 70 researchers, and was held for the second year during the annual meeting of the Society for Investigative Dermatology to review ongoing studies funded by grants from the National Rosacea Society and to foster increased scientific interest in rosacea research.

The greater warmth of the facial skin of rosacea sufferers may play a role in triggering the unsightly bumps and pimples that are common signs of this disorder, according to a new study funded by a grant from the National Rosacea Society and reported at the recent annual meeting of the Society for Investigative Dermatology.

Medical researchers reviewed scientific progress in understanding the potential causes and other aspects of rosacea during a recent research workshop conducted by the National Rosacea Society. The well-attended session was held during the annual meeting of the Society for Investigative Dermatology to stimulate further rosacea research and broaden awareness of research grants now available from the National Rosacea Society.

Growing evidence now confirms that rhinophyma, the excess growth of tissue on the nose that represents the most advanced stage of rosacea, is a result of the chronic lymphedema (swelling) that often appears in rosacea, according to a new study published in the Journal of the American Academy of Dermatology.¹
