Stress and the skin. G Ital Dermatol Venereol. 2010 Apr;145(2):213-9 Authors: Reich A, Wójcik-Maciejewicz A, Slominski AT Emotional stress can affect, reveal or even exacerbate a number of skin disorders including psoriasis, atopic dermatitis, pruritus, alopecia areata, lichen planus, seborrheic dermatitis, rosacea or urticaria, although the direct pathophysiologic link between stress factors and cutaneous disease manifestation remains unclear. However, there is an increasing evidence that stress influences disease processes and contributes to the inflammation through modulating hypothalamic-pituitary-adrenal axis and releasing neuropeptides, neurotrophins, lymphokines and other chemical mediators from nerve endings and dermal cells. The central role in cellular skin reactivity to various stressors might be attributed to dermal mast cells, as they show close connections with sensory nerve endings and may release a huge number of proinflammatory mediators. However, many other cells also actively take part in skin response to stress. Although our knowledge is still not complete, one of the most distinct aspect is that the skin, endocrine, nervous and immune systems cannot longer be treated autonomously, but have to be considered as a large multidirectional complex of which interacting nature is still poorly understood.

Rosaceiform dermatitis associated with topical tacrolimus treatment. J Am Acad Dermatol. 2010 Jun;62(6):1050-2 Authors: Fujiwara S, Okubo Y, Irisawa R, Tsuboi R We describe herein 3 patients who developed rosacea-like dermatitis eruptions while using 0.03% or 0.1% tacrolimus ointment for facial dermatitis. Skin biopsy specimens showed telangiectasia and noncaseating epithelioid granulomatous tissue formation in the papillary to mid dermis. Continuous topical use of immunomodulators such as tacrolimus or pimecrolimus should be regarded as a potential cause of rosaceiform dermatitis, although many cases have not been reported.

J Am Acad Dermatol. 2010 May 10; Authors: McAleer MA, Fitzpatrick P, Powell FC BACKGROUND: The prevalence and pathogenesis of rosacea is uncertain. Previously, studies used varying definitions of disease and have not explored the relationship of its prevalence to ultraviolet (UV) exposure or photodamage. OBJECTIVES: We investigated the prevalence of papulopustular rosacea (PPR) and its relationship to UV radiation exposure in 1000 randomly selected Irish individuals. METHODS: A total of 1000 individuals (500 with low UV exposure and 500 with high UV exposure) were examined. PPR was diagnosed using a standardized definition and photodamage was assessed using a photodamage scale. RESULTS: The prevalence of PPR was 2.7%. PPR prevalence was not significantly related to photodamage or UV exposure. LIMITATIONS: The power to compare UV exposure among those with and without PPR was limited. CONCLUSIONS: PPR prevalence in Ireland was 2.7%. UV radiation exposure does not appear to affect the prevalence of PPR.

Clin Exp Dermatol. 2010 Apr 26; Authors: Jarrett R, Gonsalves R, Anstey AV Summary Rosacea fulminans (RF) is a rare facial dermatosis characterized by the sudden onset of severe facial inflammation consisting of numerous pustules, cystic swellings and coalescing sinuses. The standard treatment is the retinoid drug isotretinoin in combination with systemic corticosteroids or with high-dose oral tetracycline antibiotics. We report three recent cases of RF in pregnancy with differing obstetric outcomes: an intrauterine death, a termination of pregnancy, and a normal vaginal delivery. The pathogenesis of RF is considered and therapeutic options in pregnancy are reviewed.

Am J Clin Dermatol. 2010;11(3):217-22 Authors: McKeage K, Deeks ED Anti-inflammatory dose doxycycline 40 mg capsules (30 mg immediate-release and 10 mg delayed-release beads) provide a sub-antimicrobial dose that reduces the inflammatory response in patients with rosacea without producing drug concentrations required to treat bacterial diseases. The efficacy of oral, anti-inflammatory dose doxycycline 40 mg capsules once daily in the treatment of adults with rosacea was demonstrated in two pivotal large, randomized, double-blind, placebo-controlled, multicenter trials. After 16 weeks' therapy, anti-inflammatory dose doxycycline 40 mg was significantly more effective in improving rosacea than placebo, providing a greater reduction in the total inflammatory lesion count (primary endpoint) than placebo. Anti-inflammatory dose doxycycline 40 mg was associated with a rapid onset of action, achieving a significantly greater decrease in total inflammatory lesion count than placebo by the first follow-up visit at week 3 in both studies. Maximum anti-inflammatory efficacy appears to be achieved with doxycycline 40 mg capsules once daily, as no additional improvement in rosacea symptoms was achieved with oral doxycycline 100 mg once daily (usual antibacterial dosage) in a small, randomized, double-blind trial. Anti-inflammatory dose doxycycline 40 mg was generally well tolerated in clinical trials, with most adverse events being of mild to moderate intensity.

Iron toxicity: New conditions continue to emerge. Oxid Med Cell Longev. 2009 Apr;2(2):107-9 Authors: Weinberg ED During the past half century, excessive/misplaced iron has been observed to be a risk factor for an increasing number and diversity of disease conditions. An extensive list of conditions and of the types of iron association were published in early 2008. Within the subsequent year, four additional disorders have been recognized to be enhanced by iron: aging muscle atrophy, viral replication, rosacea and pulmonary alveolar proteinosis.

Related ArticlesSystemic isotretinoin in the treatment of rosacea - doxycycline- and placebo-controlled, randomized clinical study. J Dtsch Dermatol Ges. 2010 Mar 12; Authors: Gollnick H, Blume-Peytavi U, Szabó EL, Meyer KG, Hauptmann P, Popp G, Sebastian M, Zwingers T, Willers C, von der Weth R Summary Background: Systemic isotretinoin has been known for decades to be effective in the treatment of severe forms of rosacea, but it must be used off-label because of the lack of evidence-based data. Patients and Methods: 573 patients with rosacea subtype II and III received one of three different dosages of isotretinoin (0.1 mg, 0.3 mg, or 0.5 mg per kg body weight), doxycycline (100 mg daily for 14 days, then 50 mg daily) or placebo in a double-blinded, randomized way for 12 weeks in 35 German centers. Results: Isotretinoin 0.3 mg/kg proved to be the most effective dose with significant superiority versus placebo. Isotretinoin 0.3 mg/kg showed also significant non-inferiority versus doxycycline with reduction of lesions of 90 % compared to 83 % with doxycycline. Investigators diagnosed complete remission in 24 % and marked improvement in further 57 % of patients with isotretinoin treatment, in contrast to remission in 14 % and marked improvement in 55 % of patients treated with doxycycline. Isotretinoin 0.3 mg/kg revealed a similar safety profile as for the treatment of acne. Isotretinoin 0.5 mg/kg showed more dermatitis facialis as compared to 0.3 mg/kg. Conclusions: Isotretinoin 0.3 mg/kg is an effective and well-tolerated therapy option for the treatment of rosacea subtype II and III and can therefore be used successfully as an alternative to therapy with oral antibiotics.

Related ArticlesSurgical treatment of rhinophyma using carbon dioxide (CO(2)) laser and pulsed dye laser (PDL). J Cosmet Laser Ther. 2010 Apr;12(2):73-6 Authors: Moreira A, Leite I, Guedes R, Baptista A, Mota G Abstract Rhinophyma is a slowly progressive, benign dermatological disorder of the nose. The most widely accepted theory is that rhinophyma is the end stage of chronic rosacea. The primary reason for its excision is cosmetic deformity. Many treatment modalities have been described, including CO(2) laser. This method provides a very dry surgical field, which allows the sculpting of the hypertrophic areas. Pulsed dye laser (PDL) is a safe and effective treatment, resulting in a significant improvement in erythema, telangiectases, symptoms and quality of life. We report the case of a 63-year-old Caucasian man with a 2-year history of rapid progression rhinophyma. The patient was submitted to five CO(2) laser sessions, followed by three PDL sessions. Favourable re-epithelization of the surfaces treated with CO(2) laser was achieved within a very short period of time. PDL post-treatment purpura lasted a medium of 12 days. After 12 months of follow-up the patient remains without evidence of relapse. To our knowledge, this is the first case described of treatment using a combination of the CO(2) laser and PDL.

The multifunctionality of 10% sodium sulfacetamide, 5% sulfur emollient foam in the treatment of inflammatory facial dermatoses. J Drugs Dermatol. 2010 Mar;9(3):234-6 Authors: Draelos ZD Prior to 1962, some of the most versatile drugs in dermatology were approved by the U.S. Food and Drug Administration (FDA) solely on the basis of safety. One of these is the combination 10% sodium sulfacetamide and 5% sulfur. Sodium sulfacetamide possesses anti-inflammatory and antibacterial properties while sulfur is a nonspecific antibacterial and antifungal. A new emollient foam formulation of 10% sodium sulfacetamide and 5% sulfur allows a thinner application film and leaves behind no residue on hair bearing or non-hair bearing skin. The sulfur smell is also more quickly dissipated with reduced irritation. This uncontrolled, observational, prospective, open-label, single site, eight-week study enrolled 24 subjects (eight with rosacea, eight with seborrheic dermatitis, eight with acne vulgaris) to evaluate the safety and efficacy of this novel foam formulation. At eight weeks, statistically significant improvement was seen in inflammatory rosacea lesion counts and the signs of seborrheic dermatitis. A 50% reduction was noted in the total acne lesion counts. These findings confirm the versatility of an emollient 10% sodium sulfacetamide and 5% sulfur foam.

Related ArticlesControl of cutaneous antimicrobial peptides by vitamin D3. Arch Dermatol Res. 2010 Mar 10; Authors: Dombrowski Y, Peric M, Koglin S, Ruzicka T, Schauber J Constant exposure to a wide variety of microbial pathogens represents a major challenge for our skin. Antimicrobial peptides (AMPs) are mediators of cutaneous innate immunity and protect primarily against microbial infections. Cathelicidins were among the first AMPs identified in human skin and recent evidence suggests that they exert a dual role in innate immune defense: At first, due to their antimicrobial activity they kill pathogens directly. In addition, these peptides initiate a potent host response to infection resulting in cytokine release, inflammation and a cellular response. Disturbed cathelicidin expression and function was observed in several common inflammatory skin diseases, such as psoriasis where cathelicidin peptide converts inert self-DNA and self-RNA into an autoimmune stimulus. In atopic dermatitis decreased levels of cathelicidin facilitating microbial superinfections have been discussed. Furthermore, abnormally processed cathelicidin peptides induce inflammation and a vascular response in rosacea. Until recently, the molecular mechanisms underlying cathelicidin regulation were unknown. Recently, the vitamin D3 pathway was identified as the major regulator of cathelicidin expression. Consequently, vitamin D3 entered the spotlight as an immune modulator with impact on both innate and adaptive immunity. Therapies targeting vitamin D3 signaling may provide new approaches for infectious and inflammatory skin diseases by affecting both innate and adaptive immune functions.

Related ArticlesCarbon dioxide laser treatment of rhinophyma: a review of 124 patients. Br J Dermatol. 2009 Oct;161(4):814-8 Authors: Madan V, Ferguson JE, August PJ BACKGROUND: Rhinophyma is a progressive, localized or generalized nasal deformity resulting from hypertrophy of sebaceous and connective tissue. The CO(2) laser has been used for treatment of rhinophyma, but the long-term efficacy of the treatment is unknown. OBJECTIVES: To review the outcome of 124 patients with rhinophyma treated with the CO(2) laser between 1996 and 2008 in our centre. PATIENTS AND METHODS: Exuberant sebaceous tissue was ablated using the Sharplan 40C CO(2) laser (Sharplan Lasers UK Ltd, London, U.K.) under local anaesthesia. The technique varied with the severity of rhinophyma; the laser was used in a continuous mode to debulk the larger rhinophymas, and in a resurfacing mode (Silk Touch scanner; Sharplan, 4-7-mm spot at 20-40 W) or continuous mode (10-20 W using a defocused 2-3-mm beam) to reshape the nasal contours. Outcomes were determined by case notes, clinical review and questionnaire. RESULTS: Laser treatment was completed in a single session in 115 of 124 patients. All patients were reviewed 3 months post-treatment. Results were classified as good to excellent in 118 and poor in six patients. All patients were sent a satisfaction questionnaire in 2008 and 52 patients replied. Patients reported high levels of satisfaction following treatment. The post-treatment response at 3-month review was maintained long term. The main complications were pain associated with injection of local anaesthetic, scarring and hypopigmentation (four patients) and open pores (two patients). CONCLUSIONS: The CO(2) laser is an effective and durable treatment for rhinophyma. Treatment carries a low risk of side-effects and is associated with high patient acceptability and satisfaction.

Related ArticlesComparison of the two techniques for measurement of the density of Demodex folliculorum: standardized skin surface biopsy and direct microscopic examination. Br J Dermatol. 2010 Feb 25; Authors: Aşkın U, Seçkin D Summary Background In daily dermatological practice, many dermatologists do not include demodicosis in their differential diagnoses, or the diagnosis of demodicosis is frequently masked by other skin diseases such as papulopustular or erythematotelangiectatic rosacea, seborrhoeic dermatitis, perioral dermatitis and contact dermatitis. There are two methods for measurement of the density of Demodex folliculorum (Dd): standardized skin surface biopsy (SSSB) and direct microscopic examination of fresh secretions from sebaceous glands (DME). No study has been reported in the literature comparing the diagnostic value of these two techniques. Objectives To compare the value of the two techniques, SSSB and DME, for the measurement of Dd in patients with suspected demodicosis. Methods Mite density was investigated using SSSB and DME in 37 patients with facial skin lesions suggesting demodicosis. Two samples, one for SSSB and one for DME, were obtained from a cheek lesion of each patient. Results Twenty-three (62%) patients were diagnosed with demodicosis according to their clinical manifestations combined with a high Dd (Dd > 5 mites cm(-2)) with SSSB and/or DME. In all the patients, the mean Dd measured with SSSB was higher than that with DME (22.9 +/- 5.9 and 2.2 +/- 0.8, respectively; P = 0.001). Also, among the 23 patients with demodicosis, the mean Dd measured using SSSB was higher than the mean Dd with DME (36.5 +/- 8.3 and 3.4 +/- 1.2, respectively; P = 0.0001). Conclusions We recommend the use of SSSB for the measurement of Dd as more patients with demodicosis can be diagnosed with this method compared with the DME method.

Mucin is not a rare finding in rosacea. Rom J Morphol Embryol. 2010;51(1):69-72 Authors: Fernandez-Flores A Mucin deposit is a feature that is not commonly mentioned in textbooks when talking about rosacea. Nevertheless, it is one of the prominent findings of a severe variant of the phymatous type of rosacea known as the fibrous type. We retrospectively investigated 20 cases of early stages of rosacea and examined the mucin deposit in them, with histochemical stains (Alcian Blue and Periodic Acid-Schiff). We found granulomas in 20% of these cases. Alcian Blue positive deposits of mucin were found in all cases with granulomas. The mucin was located in the granulomas (four cases) as well as in the infundibulum (one case). No deposits of mucin were evidenced in the dermis out of the granulomas, apart from the normal mucin of papillary and adventicial dermis. Periodic Acid-Schiff did not show any deposits in any case. Serologic lupus markers were negative in all patients with mucin deposits. We conclude that: (a) mucin is a common finding in granulomas of rosacea; ( this mucin is probably not related to any progression to the mucinous variant of rhinophyma; © since discoid erythematosus lupus is a clinical differential of rosacea, it is important to be aware of the fact that mucin is a common finding in the granulomas, in order not to misdiagnose both entities.

[Helicobacter pylori infection and autoimmune disease such as immune thrombocytopenic purpura] Kansenshogaku Zasshi. 2010 Jan;84(1):1-8 Authors: Ohta M Helicobacter pylori infection is implicated in the pathogenesis of extradigestive diseases such as acne rosacea and idiopathic chronic urticaria and autoimmune diseases such as autoimmune gastric atrophy, rheumatoid arthritis, anti phospholipid antibody syndrome, autoimmune thyroiditis, Sjoegren syndrome, Henoch-Schoenlein purpura, and Type B insulin resistance syndrome. H. pylori eradication ameliorated the condition in some, but not all, of those with these autoimmune diseases. Recent studies primarily in Italy and Japan found that H. pylori eradication in those infected with chronic immune thrombocytopenic purpura (ITP) results in a persistent platelet count increase in over half of those treated, suggesting that although pathogenetic mechanisms underlying the relationship between H. pylori infection and autoimmune disease remain unclear, yet-unknown immunological events induced by H. pylori infection almost certainly occur in the development of autoimmune response. A majority of isolated H. pylori strains express human Lewis (Le(x) and/or Le(y) determinants and in some strains, Le(a), Le(, sialyl-Le(x)), and H determinants in the O-chain of the surface lipopolysaccharide. Previous studies showed that this molecular mimicry helps the bacterium evade host responses while evoking autoantibody responses to Le antigens. The anti-Le(y) autoantibody is also reported to promote H. pylori adhesion to gastric epithelial cells, leading to development of gastric atrophy. Moreover, one can hypothesize that anti-Le autoreactive antibodies induced by H. pylori infection are involved in the development of autoimmune diseases, although no clinical studies showing that anti-Le immune responses are involved in the etiology of these autoimmune diseases have been conducted. Proving this hypothesis would require quantitative and qualitative analysis of autoantibodies and T cell functions to Le antigens. High frequent phase variation of Le structures in the O-polysaccharide of H. pylori may influence the immune response of patients to Le antigens.

Current treatments include topical retinoids, benzoyl peroxide, topical and systemic antibiotics, and systemic isotretinoin. There are growing concerns of rising antibiotic resistance, significant side effects of isotretinoin therapy, and lack of safe and effective treatment for pregnant females. Recent advances in the pathogenesis of acne have led to a greater understanding of the underlying inflammatory mechanisms and the role the Propionibacterium acnes and biofilms. This has led to the development of new therapeutic targets.

Augmentin Duo in the Treatment of Childhood Blepharokeratoconjunctivitis. J Pediatr Ophthalmol Strabismus. 2010 Feb 8;:1-5 Authors: Cehajic-Kapetanovic J, Kwartz J PURPOSE:To report the use of Augmentin Duo 400/57 (GlaxoSmithKline, Middlesex, UK) in the treatment of childhood blepharokeratoconjunctivitis (BKC). METHODS:This is a retrospective interventional case series. The case notes of 7 consecutive patients treated with Augmentin Duo 400/57 for BKC during 18 months were reviewed. Diagnostic criteria for BKC were blepharitis including recurrent chalazia and meibomian gland dysfunction, eyelid margin telangiectasia and facial rosacea, recurrent episodes of chronic red eye, photophobia, watering, punctate superficial keratopathy, corneal neovascularization, and corneal ulcers. RESULTS:Seven children (age range: 6 to 14 years) were diagnosed as having BKC. All children received systemic Augmentin Duo 400/57 and showed considerable improvement within the first month of therapy. Six children had no recurrences during a mean follow-up of 6 months. No patients experienced any side effects from this treatment. CONCLUSIONS:Augmentin Duo 400/57 has not previously been reported in the treatment of BKC in children. In this case series, Augmentin Duo 400/57 proved to be at least as effective as current treatments with systemic erythromycin or doxycycline with the advantage of a twice-daily dosage and a superior side-effect profile.

Related ArticlesThe role of tetracyclines in rosacea. Am J Clin Dermatol. 2010;11(2):79-87 Authors: Alikhan A, Kurek L, Feldman SR There is a great deal of evidence to support the use of tetracycline and doxycycline in the treatment of papulopustular rosacea. Nevertheless, these agents have shared and unique adverse effects and relative contraindications. Recently, subantimicrobial-dose doxycycline was demonstrated to be an effective treatment for rosacea, due to its inherent anti-inflammatory properties. Furthermore, subantimicrobial-dose doxycycline has a more preferable tolerability profile and a lower occurrence of bacterial resistance than traditional-dose doxycycline. To further elucidate the role of tetracycline agents in rosacea, clinical trials that compare these agents with each other as well as with other effective rosacea treatments are called for. Adherence studies comparing oral tetracycline treatment with topical metronidazole treatment may also enhance clinical decision making.
