    What is Rosacea?
    Rosacea is a chronic and sometimes progressive disorder of the face, characterized by some or all of the following symptoms:

    Extremely sensitive facial skin with blushing, flushing, permanent redness, burning, stinging, swelling, papules, pustules, broken red capillary veins, red gritty eyes (which can lead to visual disturbances) and in more advanced cases, a disfiguring bulbous nose. Men and women of all ages can be affected, with over 415 million estimated rosacea sufferers worldwide

    "Rosacea is probably a collection of many different diseases that are lumped together inappropriately." Zoe Diana Draelos, MD. 
    Dr. Draelos is a member of the ROSIE [ROSacea International Expert] Group that says the subtype classification of rosacea is controversial. Dr. Draelos is also a member of the RRDi MAC. Just because you have a red face might mean you have another skin condition instead of or with rosacea, since other skin conditions may co-exist with rosaceamimic rosacea or you might have a rosacea variant (over a dozen variants to differentiate).  

    "Rosacea is a multifactorial, hyper-reactivity, vascular and neural based disease with a broad range of facial manifestations where normal vasodilation is greater and more persistent and involves an autoimmune component of microscopic amounts of extravasated plasma induce localized dermal inflammation that may induce repeated external triggers, vasodilation, telangiectasias, redness with eventual fibrosis and hypertrophic scarring of the dermis." Sandra Cremers, M.D., F.A.C.S., RRDi MAC Member.

    If you note, there are different definitions of what constitutes rosacea which is common. Clarity with phenotypes (see below) helps in a differential diagnosis. 

    Phenotypes
    In November 2016, the RRDi endorsed the phenotype classification of rosacea which was announced by the ROSCO panel as a better approach of diagnosising rosacea than using subtypes.

    Rosacea Differential Diagnosis and Misdiagnosis
    Your physician should differentiate rosacea from a plethora of other skin conditions. If you need photos of rosacea click here.

    Sometimes rosacea is misdiagnosed.

    Treatment
    'There are a number of topical, oral and systemic treatments available. Yet, treatment for rosacea remains difficult." Expert Opinion Pharmacotherapy 

    “There’s no one treatment that’s going to work for everybody, but we evaluate each patient individually and try to select the treatments from our armamentarium that we think will be the simplest and safest for long-term control.” John Meisenheimer, MD, Orlando, The City's Magazine

    ""Ultimately, rosacea is a subjective and entirely individual experience." Rosacea: Beyond the visable

    Cause of Rosacea
    No one really knows what causes rosacea and there are a number of theories for your consideration. Our latest article on this subject, Rosacea Theories Revisited is worth your time to consider.

    • Comparative effectiveness of purpuragenic 595 nm pulsed dye laser versus sequential emission of 595 nm pulsed dye laser and 1,064 nm Nd:YAG laser: a double-blind randomized controlled study. Acta Dermatovenerol Alp Pannonica Adriat. 2019 Mar;28(1):1-5 Authors: Campos MA, Sousa AC, Varela P, Baptista A, Menezes N Abstract INTRODUCTION: Erythematotelangiectatic rosacea is a common condition in Caucasians. The most frequently used lasers to treat this condition are pulsed dye laser (PDL) and neodymium:yttrium-aluminum-garnet laser (Nd:YAG). This study compares the treatment efficacy of purpuragenic PDL with that of sequential emission of 595 nm PDL and 1,064 nm Nd:YAG (multiplexed PDL/Nd:YAG). METHODS: We performed a prospective, randomized, and controlled split-face study. Both cheeks were treated, with side randomization to receive treatment with PDL or multiplexed PDL/Nd:YAG. Efficacy was evaluated by spectrophotometric measurement, visual photograph evaluation, the Dermatology Quality of Life Index questionnaire, and a post-treatment questionnaire. RESULTS: Twenty-seven patients completed the study. Treatment was associated with a statistically significant improvement in quality of life (p < 0.001). PDL and multiplexed PDL/Nd:YAG modalities significantly reduced the erythema index (EI; p < 0.05). When comparing the degree of EI reduction, no differences were observed between the two treatment modalities. PDL was associated with a higher degree of pain and a higher percentage of purpura. Multiplexed PDL/Nd:YAG modality was associated with fewer side effects and greater global satisfaction, and 96.3% of the patients would recommend this treatment to a friend. CONCLUSIONS: Both laser modalities are efficacious in the treatment of erythematotelangiectatic rosacea. The multiplexed PDL/Nd:YAG modality was preferred by the patients.

    • Logo of the Human Microbiome Project, a program of the NIH Common Fund, National Institutes of Health, image courtesy of Wikimedia Commons This subject of microbiome-based therapeutic strategies for rosacea is one of my favorite subjects which I have done a great deal of research on. You may want to read the latest article I have written on this subject of the human microbiome. 
    • Related Articles Skin diseases are more common than we think: screening results of an unreferred population at the Munich Oktoberfest. J Eur Acad Dermatol Venereol. 2019 Mar 19;: Authors: Tizek L, Schielein MC, Seifert F, Biedermann T, Böhner A, Zink A Abstract BACKGROUND: Skin diseases are ranked as the fourth most common cause of human illness, resulting in an enormous non-fatal burden. Despite this, many affected people do not consult a physician. Accordingly, the actual skin disease burden might be even higher since reported prevalence rates are typically based on secondary data that exclude individuals who do not seek medical care. OBJECTIVE: The aim of the study was to investigate the prevalence of skin diseases in an unreferred population in a real-life setting. METHODS: A cross-sectional study of 9 days duration was performed in 2016 at the 'Bavarian Central Agricultural Festival', which is part of the Munich Oktoberfest. As part of a public health check-up, screening examinations were performed randomly on participating visitors. All participants were 18 years or older and provided written informed consent. RESULTS: A total of 2701 individuals (53.5% women, 46.2% men; mean age 51.9 ± 15.3 years) participated in the study. At least one skin abnormality was observed in 1662 of the participants (64.5%). The most common diagnoses were actinic keratosis (26.6%), rosacea (25.5%) and eczema (11.7%). Skin diseases increased with age and were more frequent in men (72.3%) than in women (58.0%). Clinical examinations showed that nearly two-thirds of the affected participants were unaware of their abnormal skin findings. CONCLUSION: Skin diseases might be more common than previously estimated based on the secondary data of some sub-populations. Further information and awareness campaigns are needed to improve people's knowledge and reduce the global burden associated with skin diseases.

    • Fractionated Carbon Dioxide Laser Resurfacing as an Ideal Treatment Option for Severe Rhinophyma: A Case Report and Discussion. J Clin Aesthet Dermatol. 2019 Jan;12(1):24-27 Authors: Comeau V, Goodman M, Kober MM, Buckley C Abstract Rhinophyma is a progressive, disfiguring condition that affects the nose and is caused by the hypertrophy of sebaceous glands and connective tissue. Although its exact pathogenesis remains unclear, it is generally thought to be a subtype of the chronic, inflammatory condition rosacea. To date, oral and topical treatments have been largely ineffective at treating rhinophyma. Laser resurfacing is an emerging treatment modality that offers hope for patients with severe rhinophyma. We present a case of rhinophyma treated via fractionated carbon dioxide laser resurfacing with impressive results, excellent tolerability, and minimal downtime.

    • Effective Treatment of Morbihan's Disease with Long-term Isotretinoin: A Report of Three Cases. J Clin Aesthet Dermatol. 2019 Jan;12(1):32-34 Authors: Olvera-Cortés V, Pulido-Díaz N Abstract Morbihan's disease is characterized by the presence of chronic and persistent edema of the periorbital tissue, forehead, glabella, nose, and cheeks. In some cases, it is related to acne and rosacea, but its exact etiology remains unknown. A defined therapeutic approach has yet to be established for the treatment of Morbihan's disease. To date, the systemic and surgical options attempted have not been very successful and/or do not yield sustained results. Isotretinoin is a key systemic treatment used for the treatment of various skin conditions. However, there are few reports of isotretinoin being used to treat Morbihan's disease. Here, we present the details of three patients with Morbihan's disease who were successfully treated long-term with isotretinoin. PMID: 30881575 [PubMed] {url} = URL to article
    • They have now discovered that humans might be divided into three types of gut bacteria: Bacteroides, Prevotella and Ruminococcus, which may lead to personalizing medical treatment based upon which type gut microbes you predominantly have. "The three gut types can explain why the uptake of medicines and nutrients varies from person to person," [1] and may develop into a new ‘biological fingerprint’ on the same level as blood types and tissue types, akin to the 'blood type' diet and treatments. That is why probiotic treatment for rosacea is as valid, if not much better, as antibiotic treatment.  Bacteroides Bacteroides is a genus of Gram-negative, obligate anaerobic bacteria. Bacteroides species are non endospore-forming bacilli, and may be either motile or nonmotile, depending on the species. The DNA base composition is 40–48% GC. Unusual in bacterial organisms, Bacteroides membranes contain sphingolipids. They also contain meso-diaminopimelic acid in their peptidoglycan layer. Bacteroides species are normally mutualistic, making up the most substantial portion of the mammalian gastrointestinal microbiota, where they play a fundamental role in processing of complex molecules to simpler ones in the host intestine. As many as 1010–1011 cells per gram of human feces have been reported. They can use simple sugars when available; however, the main sources of energy for Bacteroides species in the gut are complex host-derived and plant glycans.[8] Studies indicate that long-term diet is strongly associated with the gut microbiome composition—those who eat plenty of protein and animal fats have predominantly Bacteroides bacteria, while for those who consume more carbohydrates the Prevotella species dominate.[2] Prevotella Prevotella is a genus of Gram-negative bacteria. Prevotella spp. are members of the oral, vaginal, and gut microbiota and are often recovered from anaerobic infections of the respiratory tract. These infections include aspiration pneumonia, lung abscess, pulmonary empyema, and chronic otitis media and sinusitis. They have been isolated from abscesses and burns in the vicinity of the mouth, bites, paronychia, urinary tract infection, brain abscesses, osteomyelitis, and bacteremia associated with upper respiratory tract infections. Prevotella spp. predominate in periodontal disease and periodontal abscesses. Research of human microbiota show that human gut is mainly inhabited by two phyla of bacteria – Firmicutes and Bacteroidetes, the latter mostly dominated by Bacteroides and Prevotella genera. Prevotella and Bacteroides are thought to have had a common ancestor. Formally, the two genera were differentiated in 1990. [3] Ruminococcus Ruminococcus is a genus of bacteria in the class Clostridia. They are anaerobic, Gram-positive gut microbes. One or more species in this genus are found in significant numbers in the intestines of humans. The type species is R. flavefaciens. As usual, bacteria taxonomy is in flux, with Clostridia being paraphyletic, and some erroneous members of Ruminococcus being reassigned to a new genus Blautia on the basis of 16S rRNA gene sequences.
