  1. Potential association between rosacea and cancer: A study in a medical center in southern China. J Dermatol. 2019 May 23;: Authors: Long J, Li J, Yuan X, Tang Y, Deng Z, Xu S, Zhang Y, Xie H Abstract Growing evidence suggests that rosacea increases the risk of systemic diseases, but studies of the relationships between rosacea and cancer are rare. Aimed to assess the relationship between rosacea and cancer, a total of 7548 patients with confirmed internal malignancies and 8340 cancer-free individuals aged 18 years or more were included in this study from November 2015 to October 2017. Clinical characteristics, personal history and laboratory data were recorded when patients were diagnosed with rosacea. Logistic regression analyses were performed to analyze associations between cancer and rosacea. We found rosacea significantly affected more women than men in both cancer and cancer-free group. The data showed there was no relationship between rosacea and lung, gastrointestinal, nasopharyngeal and gynecological cancer. However, rosacea was significantly associated with the increased risk of breast cancer and glioma, but negatively associated with the risk of hematological cancer. Of the 190 female breast cancer patients with rosacea, 98.95% had the erythematotelangiectatic subtype of rosacea, 48.42% had chloasma and 76.31% of them were Fitzpatrick skin type III and IV. In our binary regression model, breast cancer patients with rosacea had a higher prevalence of estrogen receptor-positive status, lower high-density lipoprotein levels and higher low-density lipoprotein than patients with breast cancer but no rosacea. Our findings indicate that rosacea is significantly associated with higher incidence of breast cancer, glioma and lower prevalence of hematological cancer.

  2. Non-invasive objective skin measurement methods for rosacea assessment: a systematic review. Br J Dermatol. 2019 May 23;: Authors: Logger JGM, de Vries FMC, van Erp PEJ, de Jong EMGJ, Peppelman M, Driessen RJB Abstract BACKGROUND: Rosacea assessment and therapy monitoring can be challenging to standardize, as most clinical evaluation systems are prone to interobserver variability and not always validated. Objective, reliable and preferably non-invasive measurement tools are therefore needed. OBJECTIVES: To give insight into available non-invasive imaging techniques and biophysical methods in rosacea by performing a systematic review. METHODS: PubMed, EMBASE, Cochrane and Web of Science databases were searched until 1 September 2018 in accordance with PRISMA guidelines, identifying studies providing original data about objective non-invasive imaging and/or biophysical skin measurement techniques for diagnosis, assessing severity or therapy monitoring of adult patients with cutaneous facial rosacea. Risk of bias of included articles was assessed with the Cochrane Risk of Bias tool, Newcastle Ottawa Scale and Quality in Prognosis Studies tool. RESULTS: A total of 78 studies was included, describing 14 imaging and biophysical methods. Widespread information about (sub)surface cutaneous morphology and functionality was obtained. Methodological study quality was relatively low and interstudy outcome variability was large. Several tools show promising value in research settings; for treatment follow-up, Demodex mites are countable with reflectance confocal microscopy, spectrometry can quantify erythema, and rosacea severity could be objectified with skin hydration and transepidermal water loss measurements. CONCLUSIONS: This systematic review describes the spectrum of non-invasive imaging and biophysical methods in rosacea assessment, giving multifaceted information about structure and properties of rosacea skin, especially useful for research purposes. Larger studies with good methodological quality are needed to create validated protocols for further implementation into research. This article is protected by copyright. All rights reserved.

  4. Contact sensitization to cosmetic series of allergens in patients with rosacea: A prospective controlled study. J Cosmet Dermatol. 2019 May 20;: Authors: Ozbagcivan O, Akarsu S, Dolas N, Fetil E Abstract BACKGROUND: Previous studies have documented the cosmetic allergic contact dermatitis due to common cosmetic allergens in standard series and various cosmetic products used in rosacea patients; however, the prevalence of contact sensitization to other cosmetic allergens other than those in standard series is largely unknown. AIMS: To assess the prevalence of contact sensitization to a European cosmetic series of allergens (Chemotechnique Diagnostics AB, Malmö, Sweden) in rosacea patients and to compare this with the prevalence observed in general population. METHODS: In this prospective monocenter study, 103 patients with rosacea and 104 control subjects were investigated for contact sensitizations via patch testing the cosmetic series including 49 allergens. RESULTS: At least one positive allergic reaction was observed in 62 (60.2%) rosacea patients, and in 25 (24.0%) control subjects. Compared with control subjects, rosacea patients were statistically more likely to have positive patch tests. The most common allergens giving positive results were octyl gallate (10.68%), dodecyl gallate (8.74%), tert-Butylhydroquinone (7.77%), thimerosal (6.80%), euxyl K400 (6.80%), cocamidopropyl betaine (5.83%), and 2,6-Di-tert-butyl-4-cresol (4.85%). CONCLUSIONS: This study shows that rosacea patients show a strikingly high prevalence of contact sensitization to cosmetic allergens. We recommend the additional use of cosmetic series for patch testing, and the careful use of cosmetics in rosacea patients if cosmetic contact sensitivity is suspected.

  6. Related Articles Combined treatment of recalcitrant papulopustular rosacea involving pulsed dye laser and fractional microneedling radiofrequency with low-dose isotretinoin. J Cosmet Dermatol. 2019 May 18;: Authors: Kwon HH, Jung JY, Lee WY, Bae Y, Park GH Abstract BACKGROUND: While a considerable number of cases with papulopustular rosacea (PPR) are resistant to conventional medications, therapeutic regimens are not currently established. Pulsed dye laser (PDL) and fractional microneedling radiofrequency (FMR) have previously demonstrated satisfactory results for anti-angiogenesis, anti-inflammation, and dermal remodeling. AIMS: To evaluate the efficacy and safety of novel combination regimen with low-dose oral isotretinoin, PDL, and FMR in the treatment of recalcitrant PPR. PATIENTS AND METHODS: A retrospective study was undertaken for recalcitrant PPR patients to evaluate the clinical course of novel combination regimen. Twenty-five PPR patients who had failed in previous first-line therapies were enrolled. They were treated with three sessions of PDL and FMR consecutively at 4-week intervals, maintaining daily oral administration of 10 mg isotretinoin for 8 weeks. Objective assessments, erythema index measurement, and patients' subjective satisfaction were evaluated at each visit and 16 weeks after the final treatment. RESULTS: At the final follow-up visit, the number of papules and pustules decreased by 71%, and erythema index by 54% compared with baseline (P < 0.05 for both). Physician's global assessment based on rosacea severity score and patients' subjective assessments paralleled with these results. No serious side effect was observed during whole study periods. CONCLUSION: This novel combination regimen demonstrated satisfactory efficacy with reasonable safety profiles for the treatment of recalcitrant PPR.

  7. Related Articles Intense pulsed light therapy: A promising complementary treatment for dry eye disease. Arch Soc Esp Oftalmol. 2019 May 09;: Authors: Mejía LF, Gil JC, Jaramillo M Abstract OBJECTIVE: To propose the Intense Pulsed Light (IPL) therapy as a helpful supplementary treatment in patients with dry eye disease. MATERIAL AND METHODS: Retrospective cross sectional design. Medical records of patients in whom dry eye disease symptoms were not satisfactorily controlled with medical therapy alone and who underwent additional IPL with at least three sessions completed. Data were analyzed before therapy and 3weeks after its completion to asses improvement. Determination of symptoms, through a visual analog scale; tear film stability, through tear Break Up Time (tBUT); measurement of tear secretion, through Schirmer Test; and ocular surface staining with Van Bijsterveld score were evaluated. SPSS software and nonparametric analysis of repeated measures were used. The study was approved by the ethics committee. RESULTS: 50 eyes from 25 subjects were reviewed. There were 9 males (36%) and 16 females (64%), with a median age of 59years (IQR 52-64). The median of the symptoms scale was 8 (IQR 8-9) and 3 (IQR 2-4) before and after the therapy respectively (P<.05). The median of BUT was 4 (IQR 3-5) and 10 (IQR 8-11), Schirmer test was 13 (IQR 12-15) and 15 (IQR 13-20), and Van Bijsterveld score was 3 (RIC 3-4) and 2 (IQR 2-3) before and after the therapy respectively (P<.05, for all measurements). CONCLUSION: IPL treatment has excellent results regarding both: dry eye disease symptoms improvement and in office objective tests such as tBUT, Schirmer test and Van Bijsterveld score; IPL could be considered as an effective adjunct for dry eye disease.

  8. Related Articles Antimicrobial Peptide LL-37 Facilitates Intracellular Uptake of RNA Aptamer Apt 21-2 Without Inducing an Inflammatory or Interferon Response. Front Immunol. 2019;10:857 Authors: Macleod T, Ward J, Alase AA, Bridgewood C, Wittmann M, Stonehouse NJ Abstract RNA aptamers are synthetic single stranded RNA oligonucleotides that function analogously to antibodies. Recently, they have shown promise for use in treating inflammatory skin disease as, unlike antibody-based biologics, they are able to enter the skin following topical administration. However, it is important to understand the inflammatory milieu into which aptamers are delivered, as numerous immune-modulating mediators will be present at abnormal levels. LL-37 is an important immune-modifying protein upregulated in several inflammatory skin conditions, including psoriasis, rosacea and eczema. This inflammatory antimicrobial peptide is known to complex nucleic acids and induce both inflammatory and interferon responses from keratinocytes. Given the attractive notion of using RNA aptamers in topical medication and the prevalence of LL-37 in these inflammatory skin conditions, we examined the effect of LL-37 on the efficacy and safety of the anti-IL-17A RNA aptamer, Apt 21-2. LL-37 was demonstrated to complex with the RNA aptamer by electrophoretic mobility shift and filter binding assays. In contrast to free Apt 21-2, LL-37-complexed Apt 21-2 was observed to efficiently enter both keratinocytes and fibroblasts by confocal microscopy. Despite internalization of LL-37-complexed aptamers, measurement of inflammatory mediators and interferon stimulated genes showed LL-37-complexed Apt 21-2 remained immunologically inert in keratinocytes, fibroblasts, and peripheral blood mononuclear cells including infiltrating dendritic cells and monocytes. The findings of this study suggest RNA aptamers delivered into an inflammatory milieu rich in LL-37 may become complexed and subsequently internalized by surrounding cells in the skin. Whilst the results of this study indicate delivery of RNA aptamers into tissue rich in LL-37 should not cause an unwarranted inflammatory of interferon response, these results have significant implications for the efficacy of aptamers with regards to extracellular vs. intracellular targets that should be taken into consideration when developing treatment strategies utilizing RNA aptamers in inflamed tissue.

  9. A comparison of the efficacy and tolerability of topical agents used in facial Demodex treatment. J Cosmet Dermatol. 2019 May 08;: Authors: Sarac G Abstract BACKGROUND: Demodex spp. is the most common ectoparasite in humans. This parasite is believed to play a role in the etiology of many dermatological and ocular disorders. AIM: The aim of this study was to compare the efficacy and tolerability of the sulfur-sodium sulfacetamide combination, crotamiton, and permethrin, which are three topical agents commonly used in Demodex treatment. METHODS: A total of 28 patients with primary demodicosis and 44 patients with Rosacea + Demodex were included in the study. The pretreatment and post-treatment Demodex spp. counts, patient satisfaction, and erythema decrease rates were compared. RESULTS: Analysis of the efficacy of these topical agents on Demodex revealed that all three significantly decreased the number of parasites. The patient satisfaction was higher in the sodium acetamide group than the 10% crotamiton and 5% permethrin groups, and clinical evaluation (erythema/ papulopustules and white plugs) was better in the sodium acetamide group than the other groups but no statistically significant difference was found in terms of patient satisfaction and clinical evaluation. CONCLUSION: The sulfur-sodium combination, crotamiton, and permethrin are the three agents commonly used in the treatment of Demodex spp. and all significantly decreased the Demodex count. The three agents were similar in terms of tolerability. Our study needs to be supported with others on larger patient series. PMID: 31066486 [PubMed - as supplied by publisher] {url} = URL to article

Related Articles Quality of life measurement in hidradenitis suppurativa: position statement of the European Academy of Dermatology and Venereology task forces on Quality of Life and Patient-Oriented Outcomes and Acne, Rosacea and Hidradenitis Suppurativa. J Eur Acad Dermatol Venereol. 2019 Apr 29;: Authors: Chernyshov PV, Zouboulis CC, Tomas-Aragones L, Jemec GB, Svensson A, Manolache L, Tzellos T, Sampogna F, Pustisek N, van der Zee HH, Marron SE, Spillekom-van Koulil S, Bewley A, Linder D, Abeni D, Szepietowski JC, Augustin M, Finlay AY Abstract This paper is organized jointly by the European Academy of Dermatology and Venereology (EADV) Task Force (TF) on Quality of Life (QoL) and Patient-Oriented Outcomes and the EADV TF on acne, rosacea and hidradenitis suppurativa (ARHS). The purpose of this paper was to present current knowledge about QoL assessment in HS, including data on HS-specific health-related (HR) QoL instruments and HRQoL changes in clinical trials, and to make practical recommendations concerning the assessment of QoL in people with HS. HS results in significant quimp that is higher than in most other chronic skin diseases. HS impact in published studies was assessed predominantly (84% of studies) by the Dermatology Life Quality Index (DLQI). There is a lack of high-quality clinical trials in HS patients where HRQoL instruments have been used as outcome measures. One double-blind randomized placebo-controlled trial on infliximab with low number of participants reported significantly better HRQoL improvement in the treatment group than in the placebo group. Well-designed clinical studies in HS patients to compare different treatment methods, including surgical methods and assessing long-term effects, are needed. Because of lack of sufficient validation, the Task Forces are not at present able to recommend existing HS-specific HRQoL instruments for use in clinical studies. The EADV TFs recommend the dermatology-specific DLQI questionnaire for use in HS patients. The EADV TFs encourage the further development, validation and use of other HS-specific, dermatology-specific and generic instruments but such use should be based on the principles presented in the previous publications of the EADV TF on QoL and Patient-Oriented Outcomes.

  11. Related Articles [Neonatal lupus in an infant of a mother followed up for dermatomyositis: medical images]. Pan Afr Med J. 2018;31:117 Authors: Cisse L, Karabinta Y Abstract Neonatal lupus is rare. It is due to the transmission of maternal autoantibodies across the placenta during pregnancy. We here report the case of a 2-month old female infant treated for erythematous macular cutaneous lesions on the face and the trunk. Her mother was followed up for dermatomyositis diagnosed on the basis of clinical lesions, muscle weakness and elevation in muscle enzyme levels. However she had not underwent antinuclear antibody test (ANA). Clinical examination showed atrophic erythematous lesions distributed like butterfly wings on both sides of the nasal pyramid, satellite lesions on the front, with red hair. The remainder of the physical examination was unremarkable. Laboratory tests were not performed because infant's parents also refused the biopsy. These lesions suggested seborrheic dermatitis, rosacea or atopic dermatitis. However, rosacea is very rare in infants and usually affects fair-skinned people. In seborrheic dermatitis, lesions are not atrophic. The age of onset of atopic dermatitis is usually 3 months. Lesions regressed in 15 days under dermocorticoid therapy.

  12. Successful treatment of facial vascular skin diseases with a 577-nm pro-yellow laser. J Cosmet Dermatol. 2019 Apr 29;: Authors: Mohamed EM, Mohamed Tawfik K, Hassan Ahmad W Abstract BACKGROUND: Treatment of vascular skin diseases is one of the most important indications of the laser. AIMS: To evaluate the effectiveness of 577-nm pro-yellow laser in the treatment of some vascular skin diseases. PATIENTS/METHODS: Ninety-five patients with vascular skin diseases were included in this prospective monocentric study. They were classified into: port-wine stain birthmarks (n = 37), papulopustular rosacea (n = 20), facial telangiectasia (n = 16), and facial erythema (n = 22). All participants received a monthly session of 577-nm pro-yellow laser. Follow-up was done by comparing the photographs before and at every follow-up visit. RESULTS: At the final visit, there was a significant improvement (>50%) occurred in 24/37 (64.82%), 12/20 (60%), 10/16 (62.5%), and 19/22 (86.3%) cases and poor response occurred in 6/37 (16.2%), 2/20 (10%), 2/16 (12.5%), and 0/22 cases after a mean number of sessions 7.76 ± 2.28, 3.1 ± 1.8, 3.63 ± 1.12, and 1.8 ± 0.85 in port-wine stain, rosacea-, facial telangiectasia-, and facial erythema-treated groups, respectively. Transient irritation and erythema during the session were the only complications reported in the study. CONCLUSION: Facial port-wine stains, rosacea, telangiectasia, and erythema can be successfully treated with a single pass of 577-nm pro-yellow laser with a minimal side effect. Facial erythema showed the highest degree of success with the least number of sessions, while more sessions needed for the treatment of port-wine stain.

  13. Open-label study assessing the efficacy and tolerability of topical skin care and sun protection alone and in combination with intense pulsed light therapy. J Cosmet Dermatol. 2019 Apr 24;: Authors: Deaver Peterson J, Katz TM Abstract BACKGROUND: Intense pulsed light therapy (IPL) decreases facial erythema and telangiectasias associated with rosacea. Topical skin care products decrease facial erythema by the action of active ingredients and masking effects. OBJECTIVES: To assess the efficacy and tolerability of combining a topical skin care regimen (TSCR) comprised of a multifunctional three-in-one facial cream and a mineral-based brush-on SPF50 powder sunscreen with a single IPL treatment for treating mild-to-severe facial redness associated with rosacea. METHODS: Twenty female subjects with Fitzpatrick skin types I-III received TSCR monotherapy for 12 weeks. At that time, subjects received a single IPL treatment and continued TSCR for 6 additional weeks. Subjects were evaluated at Baseline and at Weeks 4, 8, 12, and 18. RESULTS: Using a 7-point redness scale, the overall mean (SD) redness score significantly improved from 3.05 (0.97) at baseline to 2.05 (0.76) at Week 18 (P < 0.01). There was a decrease in investigator-rated erythema from baseline (bare skin) to Week 12 (bare skin, before IPL) when TSCR was used as monotherapy which did not achieve significance (P = 0.12). Most subjects (80%) were satisfied or Very satisfied with the TSCR at Week 18. All subjects (100%) agreed that it improved their baseline skin redness and most (85%) would recommend TSCR to others. TSCR was well-tolerated with no significant changes in skin dryness, scaling, or itching. Mild burning occurred immediately following the IPL treatment at Week 12. CONCLUSION: TSCR in combination with a single IPL treatment produced a significant improvement in overall facial redness in patients with rosacea. Longer-term treatment with TSCR may produce continued improvement. PMID: 31017734 [PubMed - as supplied by publisher] {url} = URL to article
  14. Evaluation of the efficacy and tolerance of artemether emulsion for the treatment of papulopustular rosacea: A randomized pilot study. J Dermatolog Treat. 2019 Apr 24;:1-16 Authors: Wang GJ, Gao XY, Wu Y, He HQ, Yu Y, Qin HH, Shen WT Abstract OBJECTIVE: To assess the efficacy and safety of artemether emulsion in patients with papulopustular rosacea. METHODS: A total of 130 (randomized 1:1) were externally administered either artemether emulsion (1%) or metronidazole emulsion (3%) twice daily for 4 weeks with an open-label 8-week follow-up. The primary endpoints included the proportion of patients who achieved clinical effective responses, as well as erythema and papule and pustule score at week 4. RESULTS: Numerically more patients achieved an effective response at week 4 with artemether emulsion (87.1%) than metronidazole emulsion (80.0%) (P > 0.05). Patients with artemether emulsion had comparable baseline erythema score (2.45 ± 0.67 vs 2.42 ± 0.70, P = 0.809) and papule and pustule score (2.11 ± 0.96 vs 2.32 ± 0.83, P = 0.264), but significantly lower papule and pustule score (0.21 ± 0.52 vs 0.42 ± 0.83, P = 0.001) and comparable erythema score (0.53 ± 0.88 vs 0.62 ± 0.88, P = 0.999) compared to patients with metronidazole emulsion at week 4. There was a significantly higher proportion of patients with metronidazole emulsion relapse compared to metronidazole emulsion during the open-label 8-week follow-up period (21.6% vs 2.4%, P < 0.01). CONCLUSIONS: Artemether emulsion improved papulopustular rosacea in the metronidazole emulsion group as early as 4 weeks, but its beneficial effect was maintained through the 8-week follow-up period compared to metronidazole emulsion.

  15. Concerns and Treatment Satisfaction in Patients Being Treated With Azelaic Acid Foam for Rosacea J Drugs Dermatol. 2019 Apr 01;18(4):381-386 Authors: Williamson T, Cameron J, McLeod K, Turner B, Quillen A, LaRose A, Lott J, Gaiser A Abstract Objective: To describe patient characteristics, concerns, side effects, treatment satisfaction, and quality of life (QoL) of rosacea patients currently being treated with monotherapy azelaic acid foam based on patient-reported data. Methods: The study utilized a non-interventional, prospective, observational design. Patients were recruited in the United States and were eligible if the following criteria were met: diagnosed with rosacea by a medical professional, ≥18 years of age, currently receiving monotherapy with azelaic acid foam, and able to provide informed consent. Patients using other topical treatments for rosacea during enrollment were excluded. An online tool administered a survey of 3 questionnaires including the Rosacea Treatment Preference Questionnaire, Treatment Satisfaction with Medicines Questionnaire (SATMED-Q), and Dermatology Life Quality Index (DLQI). The survey collected demographics, clinical characteristics, treatment history, adverse events, and patient-reported outcomes related to treatment with azelaic acid foam and QoL with rosacea. Results: 54 patients met eligibility criteria. Participants were primarily female (90.7%), ranging from 26 to 63 years of age. The most common subtypes reported were erythematotelangiectatic and papulopustular (74.1% each) with 59.3% of participants reporting mild symptoms (16.7% “absent”; 24.1% “moderate”) in the 4 weeks before enrollment. The majority reported no concerns (74.1%) with their treatment. The biggest concern was cost (11.1%), with a mean importance score (IS) on a 10-point scale of 9.3. A majority (77.8%) of patients reported no side effects. Side effects reported included dryness (13%; IS: 5.3), stinging (7.4%, IS: 2.5), itching (5.6%; IS: 4.7), or burning (3.7%; IS: 7.0). Global satisfaction (SATMED-Q) mean score was 79.0 and treatment effectiveness mean score was 70.8. QoL impact of rosacea was minimal (mean DLQI score: 2.35). In regression models, increasing dryness was significantly associated with worsening outcomes in SATMED-Q and DLQI. Conclusions: Patient characteristics of the study population closely mirror the distribution of rosacea by gender and subtype as in previous estimates. Findings indicate minimal patient concerns with azelaic acid foam and primarily pertained to cost. Patient-reported side effects were rare. Minor patient-reported side effects and concerns do not appear to affect rosacea-related QoL and medication satisfaction. Compared to a previously conducted study of similar design with patients using metronidazole gel and metronidazole cream, more patients in the current study reported no concerns with their treatment, while the number of patients reporting no side effects, as well as mean SATMED-Q and DLQI scores, were similar. Further research is necessary to directly compare the results of these 2 studies. J Drugs Dermatol. 2019;18(4):381-386. PMID: 31013011 [PubMed - as supplied by publisher] {url} = URL to article
  16. Clinical picture, diagnosis and treatment of rosacea, complicated by Demodex mites. Dermatol Reports. 2019 Jan 23;11(1):7675 Authors: Kubanov A, Gallyamova Y, Kravchenko A Abstract The article analyzes the clinical picture and course of rosacea in patients with Demodex mites. It presents the advantages of using the method of confocal laser scanning microscopy over the method of light microscopy of facial skin scrapes. The aimes were to study the influence of Demodex mites on the clinical picture and course of rosacea; to compare laboratory and instrumental diagnostic methods for detecting Demodex mites; to evaluate the effectiveness of external therapy aimed at eliminating Demodex mites. 212 people were examined. The study included healthy patients, patients with a diagnosis of rosacea with the presence and absence of Demodex. The presence of Demodex mites was confirmed by two methods of study (light microscopy of skin scrapes and confocal laser scanning in vivo microscopy). Demodex mites promote the development of acute-inflammatory morphological elements, increase the duration of the condition (more than 5 years, P<0.01) and the probability of recurrence (from 1 to 3 relapses in 39.5% of patients, P<0.05), resulting in a decrease in the quality of life of patients (dermatology life quality index is 12.5±4.5, P<0.05). Antiparasitic drug ivermectin, in the form of an external form, at a concentration of 1% has a high therapeutic efficacy (in 93.3% of cases). Demodex folliculorum shows signs of parasitism, while Demodex folliculorum brevis is a saprophyte. The severity of the condition does not depend on the quantitative load of the mites in the scrape. As an antiparasitic drug, it is recommended to use 1% ivertmectin. PMID: 31007879 [PubMed] {url} = URL to article URL to Review and to full article
  17. Nanoemulsion strategy of pioglitazone for the treatment of skin inflammatory diseases. Nanomedicine. 2019 Apr 17;: Authors: Espinoza LC, Silva-Abreu M, Calpena AC, Rodríguez-Lagunas MJ, Fábrega MJ, Garduño-Ramírez ML, Clares B Abstract Pioglitazone (PGZ) is a peroxisome proliferator-activated receptor agonist. Its role in the inflammatory response modulation opens the door for additional therapeutic applications. The purpose of this study was to develop a pioglitazone nanoemulsion (PGZ-NE) to investigate its anti-inflammatory efficacy on the skin. For that a NE vehicle aimed for skin delivery was optimized and characterized. The resulting PGZ-NE showed a good anti-inflammatory efficacy by decreasing the expression of adipose inflammatory cytokines IL-6, IL-1β and TNF-α. The properties of the developed nanocarrier allowed achieving a high permeation flux of PGZ through the skin as well as high retained amount in the skin, probably due to the depot effect of ingredients, which assured a prolonged local action, with good skin tolerability among participating individuals. Consequently, these results suggest that PGZ-NE may be used as an alternative treatment for inflammatory skin diseases such as rosacea, atopic dermatitis or psoriasis.

  18. Related Articles Evaluation of Demodex mite viability using motility and scattered light intensity. Exp Appl Acarol. 2019 Apr 19;: Authors: Gatault S, Foley R, Shiels L, Powell FC Abstract Demodex mites have been suggested to have a role in various cutaneous and ocular disorders pathogenesis, such as rosacea or blepharitis. Evaluation of potential treatments with anti-Demodex effects is difficult because the viability of living mites needs to be evaluated during their exposure to the agent being tested. Mite viability is currently based solely on their observed movement. However, this method of assessing viability has significant limitations as mites may be resting, immobile or paralysed at any given observation point giving the observer a false impression of the organism's death. To overcome this limitation we evaluated a new quantitative method of evaluating the viability of Demodex mites by using scattered light intensity (SLI). We demonstrated that when combined with observation of mite motility, SLI provided increased accuracy of the evaluation of viability of mites being studied. This new viability assay will help address the technical challenges of mite viability experiments. Accurate evaluation of mite viability will enhance mite biology research and allow for more accurate in vitro toxicity assays of proposed anti-mite agents.

  19. Nonvascular uses of pulsed dye laser in clinical dermatology. J Cosmet Dermatol. 2019 Apr 19;: Authors: Forbat E, Al-Niaimi F Abstract Lasers are fast becoming the vogue of dermatology ranging from ablative, nonablative, fractional photothermolysis to vascular lasers. There are a range of vascular lasers including potassium titanyl phosphate (KTP 532 nm), pulsed dye laser (PDL -595 nm), diode (810 nm), and Nd:YAG (1064 nm). PDL is a laser that emits yellow light using Rhodamine dye as it is lasing medium. Typical vascular lesions which are treated by PDL include port wine stain, hemangioma, telangiectasia, spider angioma, and rosacea. This article focuses on the use of PDL beyond primary vascular conditions. We review the evidence, or lack thereof, of the use of PDL in acne vulgaris, scars, striae, warts, molluscum, psoriasis, rejuvenation, basal cell carcinoma (BCC), and miscellaneous dermatological sequelae.

  20. Surgical Treatment Strategy for Severe Rhinophyma With Bilateral Pedicled Nasolabial Flaps. J Craniofac Surg. 2019 Apr 12;: Authors: Cui MY, Guo S, Wang CC, Lv MZ, Jin SF Abstract BACKGROUND: Rhinophyma is a rare disease characterized by chronic inflammation and hypertrophy of sebaceous glands, blood vessels, and fibrous tissue, associated with end-stage severe acne rosacea. There are multiple approaches to treatment and repair, including dermal shaving, secondary intention healing, free skin graft, and skin flaps. However, these methods have various disadvantages, such as prolonged healing, obvious scarring, and skin texture mismatch. Therefore, the authors adopted surgical excision with bilateral pedicled nasolabial flaps, which have better color, texture, thickness, and symmetry. METHODS: The authors present a case of severe nasal tip rhinophyma successfully treated by excision and repair with bilateral pedicled nasolabial flaps. This procedure combines deep excision of the focal lesion and coverage with bilateral nasolabial flaps. RESULTS: The bilateral pedicled nasolabial flaps were used for severe rhinophyma in a patient. After the operation, the flaps survived uneventfully in this study. Both functional and aesthetic results were satisfactory at 3 months. CONCLUSION: The authors offer an effective method for surgical treatment of rhinophyma. Excision of hypertrophic nasal tissue is an acknowledged effective treatment for patients with severe rhinophyma. After excision, reconstruction with nasolabial flaps results in satisfactory outcomes both functionally and aesthetically. Therefore, this approach should be considered an appropriate alternative in cases of severe rhinophyma. PMID: 30998589 [PubMed - as supplied by publisher] {url} = URL to article

  22. Treatment of Rhinophyma With Surgical Excision and Amniotic Membrane. J Craniofac Surg. 2019 Apr 10;: Authors: Yoo JJ, Thaller SR Abstract Rhinophyma is a phenotypic subtype of rosacea affecting the nose. It is characterized by phymatous changes, skin thickening/fibrosis, glandular hyperplasia, and chronic inflammation. Treatment of severe rhinophyma is predominantly surgical excision with closure by secondary intention. Amniotic membrane has been used to promote wound healing, fibrosis, and inflammation. In this case study, the authors present a 63-year-old male with longstanding rhinophyma treated with surgical excision with intraoperative placement of amniotic membrane.

  23. Related Articles Do Dermatologic Diagnosis Change in Hot vs. Cold Periods of The Year? A Sub-Analysis of the DIADERM National Sample (Spain 2016). Actas Dermosifiliogr. 2019 Apr 11;: Authors: Gonzalez-Cantero A, Arias-Santiago S, Buendía-Eisman A, Molina-Leyva A, Gilaberte Y, Fernández-Crehuet P, Husein-ElAhmed H, Viera-Ramírez A, Fernández-Peñas P, Taberner R, Descalzo MA, García-Doval I Abstract BACKGROUND: Knowledge of seasonal variation of cutaneous disorder may be useful for heath planning and disease management. To date, however, descriptions of seasonality including all diagnoses in a representative country sample are very scarce. OBJECTIVES: To evaluate if clinical dermatologic diagnosis in Spain change in the hot vs. cold periods. MATERIALS AND METHODS: Survey based on a random sample of dermatologists in Spain, stratified by area. Each participant collected data during 6 days of clinical activity in 2016 (3 in the cold period of the year, 3 in the hot period). Clinical diagnoses were coded using ICD-10. RESULTS: With a 62% response proportion, we got data on 10999 clinical diagnoses. ICD-10 diagnostic groups that showed changes were: other benign neoplasms of skin (D23), rosacea (L71) and other follicular disorders (L73), which were more common in the hot period and acne (L70) which was more frequent in the cold period. We describe differences in the paediatric population and in private vs. public practice. Some of these differences might be associated to differences in the population demanding consultations in different periods. CONCLUSIONS: The frequency of most clinical diagnosis made by dermatologists does not change over the year. Just a few of the clinical diagnoses made by dermatologists show a variation in hot vs. cold periods. These variations could be due to the diseases themselves or to seasonal changes in the demand for consultation. PMID: 30982569 [PubMed - as supplied by publisher] {url} = URL to article

  25. Prevalence of cutaneous comorbidities in psoriatic patients and their impact on quality of life. Eur J Dermatol. 2019 Apr 10;: Authors: Caldarola G, De Simone C, Talamonti M, Moretta G, Fossati B, Bianchi L, Fargnoli MC, Peris K Abstract In contrast to the evidence for systemic co-morbidities, relatively few studies have examined the prevalence of cutaneous inflammatory co-morbidities in psoriatic patients. We conducted an observational multi-site study to measure the prevalence of cutaneous co-morbidities in adult patients with plaque psoriasis and to assess the relative impact on quality of life (QOL). Each patient attending one of the study clinics over a period of six months was evaluated to assess the presence of any concomitant skin inflammatory disease other than psoriasis at the time of the visit. Patients were also asked to complete QOL surveys at the initial visit, using DLQI, SF36, Skindex 29, and PDI. A total of 118 study participants (21.1%) had a cutaneous comorbidity. The most common cutaneous co-morbidities were rosacea (23 cases; 4.1%) and acne vulgaris (22 cases; 3.9%). Psoriatic patients with co-existing skin diseases had a worse QOL than those without, as evidenced by DLQI, Skindex 29, and PDI scores. Dermatologists should take a global approach to manage psoriatic patients by carefully evaluating the skin for any disorder and providing treatment to achieve "clean" skin.
