    We need volunteers. Could you seriously consider volunteering for the RRDi? The founder/director is appealing to millennials to think about helping others with rosacea through our non profit organization so we can keep this web site on the internet with its wealth of information on rosacea. If some don't step up to the plate and volunteer the RRDi may eventually close up shop. Seriously, do you want to see this organization cease?  Then read below why you are needed. 

    If you would like to volunteer by simply joining our cause adding you name to our list and do nothing more that is the easiest way to volunteer. At the very least join the RRDi to increase our membership and if that is all you can do we understand and appreciate whatever you can do. Your email address is all we require to join. Our goal is to reach 10,000 members. 

    Volunteers are needed to recruit more members, for fund raising, public relations, writers to write posts on our member forum, editors for the newsletter, accounting/book keeping, webmasters, forum moderators, board members, researchers, and grant writers. If you have skill not mentioned, let us know. Why not suggest what you might volunteer to do when you join the RRDi, and in the application to become a corporate member there is a place to add a comment what your volunteer skills are. If you have questions, contact us

    We would like to offer each author reimbursement if we publish the article in the next Journal of the RRDi.  If you want to volunteer to be on the publication team as an editor, author, proofreader, or any other job please join our cause and state in the comment box you want to join the Journal Publication Team.

    Volunteers are needed for the public relations committee or to write requests for donations to major corporations in our Funding Committee. Please join and mention you would like to help on the Funding Committee or for Public Relations. Or you can personally write a fund raiser letter using this sample letter.

    To Volunteer as a Writer please join. Check our announcements for special needs. Writers, editors, graphic artists and proof readers are needed! We have the ability to turn your post into an article. Why not post your article?

    • Related Articles Role of serum 25-hydroxyvitamin D levels and vitamin D receptor gene polymorphisms in patients with rosacea: a case-control study. Clin Exp Dermatol. 2018 Sep 23;: Authors: Akdogan N, Alli N, Incel Uysal P, Candar T Abstract
      BACKGROUND: Vitamin D has significant effects on the immune system and thereby on the pathogenesis of rosacea. However, there is a lack of information on the vitamin D status and vitamin D receptors (VDRs) of patients with rosacea.
      AIM: To evaluate the role of vitamin D in rosacea susceptibility.
      METHODS: A case-control study was conducted, enrolling patients with rosacea and healthy controls (HCs). Five VDR gene single nucleotide polymorphisms (SNPs) (Cdx2, FokI, ApaI, BsmI and TaqI) and serum 25-hydroxyvitamin D3 [25(OH)D3 ] levels were compared between patients and HCs.
      RESULTS: The study enrolled 60 patients (M/F: 14/46) and 60 age- and sex-matched HCs (M/F: 14/46). Age (mean ± SD) was 48 ± 11 years for both groups. The serum 25(OH)D3 levels (median ± interquartile range) were higher in patients with rosacea (12.9 ± 6.8 ng/mL) than in HCs (10.5 ± 3.7 ng/mL) (P < 0.001). Subjects with high serum 25(OH)D3 levels had a 1.36-fold increased risk of rosacea (95% CI 1.17-1.58). Heterozygous and mutant ApaI polymorphisms increased rosacea risk by 5.26-fold (95% CI 1.51-18.35) and 3.69-fold (95% CI 1.19-11.48), respectively, whereas mutant TaqI polymorphisms decreased the risk by 4.69 times (95% CI 1.37-16.67). Heterozygosity for Cdx2 alleles increased rosacea risk, whereas wildtype ApaI and mutant TaqI alleles decreased it.
      CONCLUSIONS: The present study suggests that an increase in vitamin D levels may contribute to the development of rosacea. ApaI and TaqI polymorphisms, and heterozygous Cdx2, wildtype ApaI and mutant TaqI alleles were significantly associated with rosacea. These results indicate a possible role of vitamin D and VDR pathways in the pathogenesis of rosacea, although causality could not be assessed.

    • Global Epidemiology and Clinical Spectrum of Rosacea, Highlighting Skin of Color: Review and Clinical Practice Experience. J Am Acad Dermatol. 2018 Sep 18;: Authors: Alexis AF, Callender VD, Baldwin HE, Desai SR, Rendon MI, Taylor SC Abstract
      Among individuals with skin of color, rosacea has been reported less frequently than in those with white skin, but it is not a rare disease. In fact, rosacea may be underreported and underdiagnosed in populations with skin of color because of the difficulty of discerning erythema and telangiectasia in dark skin, as well as underestimation of the susceptibility of more highly pigmented skin to dermatologic conditions like rosacea whose triggers include sun exposure. Many people with skin of color who have rosacea may experience delayed diagnosis leading to inappropriate or inadequate treatment, greater morbidity, and uncontrolled, progressive disease with disfiguring manifestations, including phymatous rosacea. This paper reviews the epidemiology of rosacea in skin of color and highlights variations in the clinical presentation of rosacea across the diverse spectrum of patient populations affected. It presents strategies to aid in the timely diagnosis and effective treatment of rosacea in patients with skin of color, with an aim of promoting increased awareness of rosacea in these patients and reducing disparities in the management of their disease.

    • Effects of dextran sulfate, 4-t-butylcyclohexanol, pongamia oil and hesperidin methyl chalcone on inflammatory and vascular responses implicated in rosacea. Clin Cosmet Investig Dermatol. 2018;11:421-429 Authors: Hernandez-Pigeon H, Garidou L, Galliano MF, Delga H, Aries MF, Duplan H, Bessou-Touya S, Castex-Rizzi N Abstract
      Background: Rosacea is a chronic facial skin disorder characterized by inflammation and vascular abnormalities. The pathophysiology of rosacea involves increased activation of the capsaicin receptor, TRPV1, the vascular endothelial growth factor (VEGF) pathway, and cathelicidin LL-37, MMP-9, and KLKs. We evaluated the activity of four compounds (dextran sulfate, 4-t-butylcyclohexanol [BCH; TRP-regulin®], pongamia oil, and hesperidin methyl chalcone [HMC]) on inflammatory and vascular responses implicated in rosacea.
      Materials and methods: The anti-inflammatory activity of dextran sulfate was evaluated on PGE2 production after PMA stimulation of NCTC-2544 keratinocytes, and on normal human epidermal keratinocytes (NHEKs) after proinflammatory stimulation to mimic a rosacea environment. The anti-angiogenic activity of dextran sulfate was measured by analyzing pseudotube formation in co-cultured human microvascular endothelial cells/normal human dermal fibroblasts. HMC modulation of vascular responses and IL-8 cytokine production after SP stimulation was evaluated in human skin explants. We also assessed the effect of BCH on TRPV1 activation, and the effect of combined BCH and pongamia oil on the inflammatory response of NHEKs.
      Results: Dextran sulfate strongly and significantly inhibited PMA-induced PGE2 production, inhibited KLK5 and MMP-9 mRNA expression, and IL-8, IL-1α and VEGF production, and displayed a highly significant inhibitory effect on VEGF-induced pseudotube formation. In SP-stimulated human skin explants, HMC significantly decreased the proportion of dilated vessels, total vessel area, and IL-8 production. BCH significantly and dose-dependently inhibited TRPV1 activation, and BCH and pongamia oil inhibited CXCL1 and CXCL6 mRNA expression and IL-8 production in NHEKs. Combined BCH/pongamia oil inhibited IL-8 production synergistically.
      Conclusion: These in vitro results showed that dextran sulfate, BCH, pongamia oil and HMC, possess complementary soothing and anti-redness properties, supporting their combination in Avène redness-relief cosmetic products for sensitive skin prone to redness, and for topical adjunctive rosacea treatment.
