    rrdi_rules.pngrrdiLogo384x64.jpg.3cd1bd79f5d066075bdd9

    1. RRDi members must be polite and respectful to fellow members taking into consideration the individual fellow member's religious, ethical, and cultural values, as well as age, race and sex. The institute determines what is polite and respectful and may or may not give warnings for violating this rule. Removal from the membership is possible for violating this rule. It is a privilege to be a member of the RRDi and not a right.

    2. To be a legal corporate voting member a name, mailing address, two email addresses, and a statement of whether the member is a rosacean or not a rosacean is required. Non voting members are only required to provide a valid email address. 

    3. Members may not profit from the institute; however, any Medical Advisory Consultants (or Committee) member or any other member may be compensated for services rendered to the institute.

    4. Members who sell items or services for rosacea may comment on a treatment, product, book or service sold by the member when another member asks for information. However, the institute may at any time stop the discussion, delete the posts or ban the member at the sole discretion of the institute. Warnings may or may not be given to the member by the institute. Profiting from contacts of fellow members through the institute is not the purpose of this non profit institute. However, information is acceptable to post when asked and appropriate comments are allowed subject to the approval by the institute. The RRDi determines if the post is appropriate or not and you agree to this decision.

    5. Voting members should state if they have a diagnosis of rosacea from a physician and failure to discuss this may be grounds for dismissal as a member. The institute needs to know which voting members are rosaceans to determine the percentage of voting members who have a diagnosis of rosacea from a physician and which voting members are not rosacea sufferers. Non voting members are also required to state if they have a diagnosis of rosacea if another member inquires.  

    6. Privacy is of concern to the institute. Names, mailing and email addresses are not given out to the public or to fellow members by the institute. Your public profile is available to anyone to view but only shows your location, country, and whether you are a rosacean if you put data into these public profile boxes. Your personal profile like first and last name, etc., is never shown to the public and only RRDi staff members can view your personal profile. You agree to allow your public profile to be shown. Members should not release names, mailing or email addresses of fellow members if you are aware of the personal contact information of a fellow member without the consent of the fellow member. A Privacy Policy is available for the public. Members who donate to the institute will be listed with their name and the amount unless the donor requests anonymity. If you want to remain anonymous please let the institute know when you donate otherwise your name will be posted without any address, phone, or email address.

    7. Members will adhere, agree to and obey the Guidelines, Charter, Articles of Incorporation, the Bylaws, the Conflict of Interest Policy and these Rules of the Institute. Violation of any of these rules may be grounds for being removed as a corporate voting member or non voting member. You may view these documents by request or check the site index.

    8. A 'rosacean' is a rosacea sufferer. 'Institute' refers to the RRDi. RRDi refers to the Rosacea Research & Development Institute. You accept these terms.

    9. Anyone can join as a non voting member and post in the forum without providing any contact information other than a valid email address. 

       10.  The Rules of the Institute may be changed at any time at the sole discretion of the institute.

    • Very good post. I also have been researching and trying to find out the ways in which mite-bacterial interaction as well as viral interaction in rosacea exacerbate the condition of inflammation.
    • Related Articles Methods for extraction and ex-vivo experimentation with the most complex human commensal, Demodex spp. Exp Appl Acarol. 2019 Dec 13;: Authors: Clanner-Engelshofen BM, French LE, Reinholz M Abstract Demodex spp. mites are the most complex organisms of the human skin microbiome and were discovered more than 175 years ago, yet only little basic research is published about them. As they can be pathophysiologically relevant ectoparasites associated with rosacea, pityriasis folliculorum, and other inflammatory skin diseases, more research should be encouraged. Being a large microorganism or a tiny animal, there are no established basic methods to handle these mites. Here, we describe techniques enabling the extraction of Demodex mites from human skin, their analysis in different ex-vivo settings, the lysis of their exoskeleton, their preservation by freezing, and observation microscopically using specific fluorescent dyes or their inherent autofluorescence. These procedures should facilitate future Demodex research and fuel further the generation of knowledge. Furthermore it is intended to ultimatively enable the mite's cultivation in vitro and reveal its pathophysiological mechanisms.

    • image courtesy of Wikimedia Commons Acne Vulgaris is a completely different disease from rosacea, but many authoritative sources report that acne vulgaris can co-exist with rosacea.[1] In past literature, acne rosacea was used to describe adult acne. [2] However, rosacea is generally confined to the facial area while acne can be not only on the facial area but also on the trunk. Treatments for acne usually irritate or exacerbate rosacea and is one of the differentiating diagnostic marker for a rosacea diagnosis. [3] [1] "It should be noted, however, that it is possible for acne vulgaris and rosacea to appear at the same time in the same patient." Medscape [2] “It is interesting that the original term for rosacea was “acne rosacea”, which has more features in common with acne than currently realized. If the “acne” portion had been retained in the later works, rosacea might have received much greater investigative attention.” A Personal Critique on the State of Knowledge of Rosacea Albert M. Kligman, M.D., Ph.D. Department of Dermatology, University of Pennsylvania, Philadelphia, PA, U.S.A. [3] What is the difference between acne and rosacea?
    • There has been at least three pharmaceutical companies researching and testing a topical minocycline for rosacea. We await to see the results of these clinical trials and if these are effective. (1) FMX103 Topical Minocycline Foam, Foamix Ltd (2) BPX-04 Minocycline Topical Gel 1%, BioPharmX, Inc.

    • image courtesy of Wikimedia Commons A genome-wide association study (GWAS) of rosacea symptom severity was conducted by Aponte et al [1] that concluded "All associations with rosacea were novel except for the HLA locus. Two of these loci (HERC-OCA2 and SLC45A2) and another precedented variant (rs1805007 in melanocortin 1 receptor) with an association P value just below the significance threshold (P = 1.3 × 10-7) have been previously associated with skin phenotypes and pigmentation, two of these loci are linked to immuno-inflammation phenotypes (IL13 and PSMB9-HLA-DMA) and one has been associated with both categories (IRF4). Genes within three loci (PSMB9-HLA-DMA, HERC-OCA2 and NRX3-DIO2) were differentially expressed in a previously published clinical rosacea transcriptomics study that compared lesional to non-lesional samples. The identified loci provide specificity of inflammatory mechanisms in rosacea, and identify potential pathways for therapeutic intervention."  "In genetics, a locus (plural loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located." Wikipedia "With the completion of the Human Genome Project in 2003 and the International HapMap Project in 2005, researchers now have a set of research tools that make it possible to find the genetic contributions to common diseases." [2] "Genome wide association studies (GWAS) are a relatively new approach to analyzing genetic sequence and have quickly become a fundamental part of modern genetic studies. Their purpose is to determine alleles that correlate to different diseases and traits." [3] "Despite clear successes in identifying novel disease susceptibility genes and biological pathways and in translating these findings into clinical care, GWAS have not been without controversy. Prominent criticisms include concerns that GWAS will eventually implicate the entire genome in disease predisposition and that most association signals reflect variants and genes with no direct biological relevance to disease."
