  1. Two is better than one: The combined effects of glycolic acid and salicylic acid on acne-related disorders. J Cosmet Dermatol. 2020 Apr 06;: Authors: Wiegmann D, Haddad L Abstract BACKGROUND: Many companies capitalized on treatable skin conditions by providing expensive prescription medications or high-end over-the-counter cosmetics. However, patients have become more apprehensive toward these medications in lieu of their often-detrimental side effect profile and reactivity with sensitive skin. AIMS: We developed a serum was created to counteract this budding problem. Our goal was to bring an alternative prescription acne medication that was superior in controlling acne when compared to several OTC and prescription-strength medications. We created a new formulary comprising primarily of all natural glycolic acid and salicylic acid. PATIENTS/METHODS: We designed a prospective study to assess the efficacy of our serum composed of glycolic and salicylic acid for patients suffering from mild to moderate inflammatory and cystic acne, rosacea, folliculitis, and keratosis pilaris. Sixty-six patients were selected ranging in age from 17 to 46. They were asked to apply the wake-up serum at night for 2 weeks. At the follow-up appointment, the patients were asked to fill out a questionnaire regarding the changes they have noticed with their skin. RESULTS: Over 90% of the patients reported they had significant overall improvement in acne with decrease in comedonal and cystic acne. 70%-80% of the patients stated decrease in oiliness, even texture, and smoother looking skin. Physical examination findings were consistent with patient-reported assessment. CONCLUSION: A glycolic and salicylic acid combination serum may be considered an alternative treatment method for patients who wish to opt out of the typical prescription medication treatment.

  2. Anxiety, Depression, and Suicidal Ideation amongst Patients with Facial Dermatoses (Acne, Rosacea, Perioral Dermatitis, and Folliculitis) in Lithuania. Dermatology. 2020 Apr 06;:1-9 Authors: Lukaviciute L, Ganceviciene R, Navickas P, Navickas A, Grigaitiene J, Zouboulis CC Abstract BACKGROUND/OBJECTIVE: Skin diseases, especially those with visible manifestation, are considered to cause a major influence on global mental health. Therefore, we determined the prevalence and severity of anxiety, depression, and suicidal ideation in a large sample of patients with facial dermatoses, namely acne, rosacea, folliculitis, and perioral dermatitis. METHODS: The mental health of patients with facial dermatoses and respective controls was assessed using the Hospital Anxiety and Depression Scale and questions concerning suicidal ideation. RESULTS: The study included 543 patients with facial dermatoses and 497 healthy individuals. Anxiety was present in 37.6% of the patients (14.9% of controls), depression in 21.7% (6.8%), and suicidal thoughts in 9.8% (3.2%) (p < 0.001). Acne patients demonstrated the highest anxiety and depression subscale scores (mean ± standard deviation: 7.1 ± 0.25, 95% confidence interval (CI): 6.58-7.56; controls: 5 ± 0.23, 95% CI: 4.57-5.49). In rosacea 30% of the patients had depression symptoms (adjusted odds ratio (OR): 7.216, 95% CI: 4.122-12.632, p < 0.001), while in folliculitis patients 15.4% (OR: 3.138, 95% CI: 1.241-7.936, p = 0.016) had suicidal thoughts. Patients with anxiety symptoms and suicidal thoughts were on average younger than those without (28.3 ± 0.76 vs. 31.2 ± 0.66 years, p = 0.001 and 25.3 ± 0.98 vs. 30.5 ± 0.55 years, p = 0.007, respectively). CONCLUSION: Acne and rosacea are associated with anxiety, depression, and suicidal ideation in Lithuanian patients. Younger patients are more prone to report such symptoms than older ones.

Chalazia are caused by an acute inflammation of sebaceous palpebral glands and lead to emergency consultation. Their treatment is most often medical, surgery is reserved for persistant forms. In case of multiple recurrent chalazia in a child, ametropia and ocular rosacea should be ruled out. The latter is a rare but potentially severe disease that can have blinding corneal complications.

  4. Related Articles The role of hypothalamus-pituitary-adrenal (HPA)-like axis in inflammatory pilosebaceous disorders. Dermatol Online J. 2020 Feb 15;26(2): Authors: Saric-Bosanac S, Clark AK, Sivamani RK, Shi VY Abstract Skin is the largest peripheral endocrine organ and functions as a hormone target and endocrine gland. A cutaneous hypothalamus-pituitary-adrenal (HPA)-like axis enables the skin to respond to stress and regulates its steroidogenic activity. The pilosebaceous unit is a site for production and metabolism of a number of steroid hormones, including stress and sex hormones. This is an overview of the important role that the cutaneous HPA-like-axis plays in the pathogenesis and treatment of inflammatory pilosebaceous disorders, including acne, rosacea, seborrheic dermatitis, and hidradenitis suppurativa.

  5. Related Articles Serum bilirubin and uric acid antioxidant levels in rosacea patients. J Cosmet Dermatol. 2020 Mar 31;: Authors: Turkmen D Abstract BACKGROUND: Rosacea is a common chronic inflammatory skin disease that the pathogenesis is not fully understood. Although the significant role of oxidative stress in rosacea pathophysiology has been shown in recent studies, there is no study addressing the potential roles of bilirubin and uric acid (UA) in rosacea. AIM: The purpose of this study was to assign serum bilirubin and UA antioxidant levels in rosacea patients. METHODS: Eighty-seven rosacea patients and 81 healthy controls (HCs) similar age and gender were included in the study. From all study participants, blood samples were taken and the values of total bilirubin (Tbil), direct bilirubin (Dbil), indirect bilirubin (Ibil), and UA were analyzed in the laboratory of biochemistry. RESULTS: The type of rosacea was erythematotelangiectatic in 51.7% of the patients, papulopustular in 43.7%, and phymatous in 4.6%. In rosacea group serum, Tbil, Dbil, Ibil, and UA values were found to be significantly lower than in the HCs. Male rosacea patients were found to have lower Tbil, Dbil, Ibil, and UA levels when compared with the males in the HCs. There was also the same significant difference in female patients. CONCLUSION: Main finding of our study was that when compared with the control group, serum bilirubin and UA levels were significantly lower in rosacea patients. These levels sustain the hypothesis that antioxidant status and oxidative stress are important in the pathogenesis of rosacea.

  6. Related Articles Epidemiological features of rosacea in Changsha, China: A population-based, cross-sectional study. J Dermatol. 2020 Mar 24;: Authors: Li J, Wang B, Deng Y, Shi W, Jian D, Liu F, Huang Y, Tang Y, Zhao Z, Huang X, Li J, Xie H Abstract Rosacea is a common chronic skin disorder of unknown etiology. While population prevalence rates range 0.2-22% in Europe and North America, prevalence in China is currently undetermined. We conducted a large population-based case-control study to determine the present epidemiological status of rosacea in China, involving 10 095 participants aged 0-100 years (mean age, 35.5 ± 19.1; 50.5% female). A census of rosacea among 15 communities in Changsha in south central China was conducted with skin examination by board-certified dermatologists. Rosacea was observed in 3.48% (95% confidence interval, 3.13-3.85%) of the study population. Subtype distribution was erythematotelangiectatic in 47.6%, papulopustular in 35.0% and phymatous in 17.4%. Family history was noted in 37.8% and ocular symptoms in 31.3%. Associations with rosacea were observed for melasma, hypertension, hyperthyroidism and breast cancer in females (P < 0.05), and also for hyperthyroidism and peptic ulcers in males (P < 0.05). Our results provide baseline information about epidemiological aspects of rosacea in China. PMID: 32207167 [PubMed - as supplied by publisher] {url} = URL to article
  7. Related Articles Rosacea is Characterized by a Profoundly Diminished Skin Barrier. J Invest Dermatol. 2020 Mar 18;: Authors: Medgyesi B, Dajnoki Z, Béke G, Gáspár K, Szabó IL, Janka EA, Póliska S, Hendrik Z, Méhes G, Törőcsik D, Bíró T, Kapitány A, Szegedi A Abstract Rosacea is a common, chronic inflammation of sebaceous gland-rich facial skin characterized by severe skin dryness, elevated pH, transepidermal water loss, and decreased hydration levels. Until now, there has been no thorough molecular analysis of permeability barrier alterations in the skin of rosacea patients. Thus, we aimed to investigate the barrier alterations in papulopustular rosacea (PPR) samples compared to healthy sebaceous gland-rich (SGR) skin, using RNASeq analysis (n=8). Pathway analyses by Cytoscape ClueGo revealed 15 significantly enriched pathways related to skin barrier formation. RT-PCR and immunohistochemistry were used to validate the pathway analyses. The results showed significant alterations in barrier components in PPR samples compared to SGR, including the cornified envelope and intercellular lipid lamellae formation, desmosome and tight junction organizations, barrier alarmins, and antimicrobial peptides. Moreover, the barrier damage in PPR was unexpectedly similar to atopic dermatitis (AD); this similarity was confirmed by immunofluorescent staining. In summary, besides the well-known dysregulation of immunological, vascular, and neurological functions, we demonstrated prominent permeability barrier alterations in PPR at the molecular level, which highlight the importance of barrier repair therapies for rosacea.

  9. Related Articles Value of reflectance confocal microscopy for the monitoring of rosacea during treatment with topical ivermectin. J Dermatolog Treat. 2020 Mar 19;:1-9 Authors: Logger JGM, Peppelman M, van Erp PEJ, de Jong EMGJ, Nguyen KP, Driessen RJB Abstract Background: Reflectance confocal microscopy (RCM) enables noninvasive Demodex mite detection in rosacea. Objective scoring of rosacea severity is currently lacking.Objectives: To determine the value of RCM for monitoring Demodex, inflammation and vascular parameters in rosacea during treatment.Methods: In 20 rosacea patients, clinical and RCM examination were performed before, during, and 12 weeks after a 16-week treatment course with topical ivermectin. Using RCM, number of mites and inflammatory cells, epidermal thickness, and vascular density and diameter were measured. RCM features were correlated with clinical assessment.Results: Treatment resulted in clinical reduction of inflammatory lesions. Mites were detected in 80% of patients at baseline, 30% at week 16, and 63% at week 28. The number of mites reduced significantly during treatment, but no changes in inflammatory cells, epidermal thickness or vascular parameters were observed. Correlation between number of inflammatory lesions and mites was low. None of the RCM variables were significant predictors for clinical success.Conclusions: RCM enables anti-inflammatory effect monitoring of topical ivermectin by determining mite presence. Quantifying exact mite number, and inflammatory and vascular characteristics is challenging due to device limitations. In its current form, RCM seems of limited value for noninvasive follow-up of rosacea in clinical practice. PMID: 32189533 [PubMed - as supplied by publisher] {url} = URL to article
  10. Related Articles Identification of Long Noncoding RNA Associated ceRNA Networks in Rosacea. Biomed Res Int. 2020;2020:9705950 Authors: Wang L, Lu R, Wang Y, Wang X, Hao D, Wen X, Li Y, Zeng M, Jiang X Abstract Rosacea is a chronic and relapsing inflammatory cutaneous disorder with highly variable prevalence worldwide that adversely affects the health of patients and their quality of life. However, the molecular characterization of each rosacea subtype is still unclear. Furthermore, little is known about the role of long noncoding RNAs (lncRNAs) in the pathogenesis or regulatory processes of this disorder. In the current study, we established lncRNA-mRNA coexpression networks for three rosacea subtypes (erythematotelangiectatic, papulopustular, and phymatous) and performed their functional enrichment analyses using Gene Onotology, KEGG, GSEA, and WGCNA. Compared to the control group, 13 differentially expressed lncRNAs and 525 differentially expressed mRNAs were identified in the three rosacea subtypes. The differentially expressed genes identified were enriched in four signaling pathways and the GO terms found were associated with leukocyte migration. In addition, we found nine differentially expressed lncRNAs in all three rosacea subtype-related networks, including NEAT1 and HOTAIR, which may play important roles in the pathology of rosacea. Our study provided novel insights into lncRNA-mRNA coexpression networks to discover the molecular mechanisms involved in rosacea development that can be used as future targets of rosacea diagnosis, prevention, and treatment.

Skin Res Technol. 2020 Mar 16;: Authors: Ma Y, Li L, Chen J, Chen T, Yuan C Abstract BACKGROUND: The updated standard classification and pathophysiology of rosacea have provided clear and meaningful evaluation parameters; however, differentiating rosacea from sensitive skin (SS) remained an obstacle for dermatologists around the world, especially in China. Herein, we aimed to find a better characteristic to distinguish rosacea from SS by using reflectance confocal microscopy (RCM). METHOD: Forty rosacea patients and 143 healthy subjects were recruited in this study. Firstly, a SS questionnaire and a lactic acid sting test were conducted among healthy subjects. Next, two major groups were divided out, including a SS group (40 subjects) and a normal skin control group (NS, 60 subjects). The cutaneous structures of face and fossa cubitalia were imaged by RCM. RESULTS: We found that more parakeratosis, honeycomb pattern, spongiform edema, and dermal papillae (P < .05) in rosacea patients than that of the NS group, whereas there were no significant differences, were found in rosacea patients and the SS group. Strikingly, we found that rosacea patients have a larger depth of honeycomb pattern than that of SS subjects (P < .05). But, the epidermal thickness of rosacea did not differ from that of SS groups. There was also no significant difference of epidermal thickness and honeycomb structure depth between rosacea patients and NS group. CONCLUSION: From the RCM images of parakeratosis, honeycomb pattern, spongiform edema, and dermal papillae, we found that RCM might be a faithful tool to distinguish rosacea from NS group. The depth of honeycomb structure of SS was more superficial than rosacea patients, whereas no significant difference between rosacea patients and NS group. RCM may provide a new method for evaluating the development of rosacea although it failed to distinguish rosacea and SS effectively.

  12. Rosa canina image courtesy of Wikimedia Commons Related Articles Molecular mechanism of the anti-diabetic activity of an identified oligosaccharide from Rosa canina. Res Pharm Sci. 2020 Feb;15(1):36-47 Authors: Bahrami G, Miraghaee SS, Mohammadi B, Bahrami MT, Taheripak G, Keshavarzi S, Babaei A, Sajadimajd S, Hatami R Abstract Background and purpose: Because of the high prevalence, diabetes is considered a global health threat. Hence, the need for effective, cheap, and comfortable therapies are highly felt. In previous study, a novel oligosaccharide with strong anti-diabetic activity in the crude extract of Rosa canina fruits, from the rosacea family, was identified. The present study was designed to ensure its efficacy using in vivo and in vitro studies. Experimental approach: Crude extract and its purified oligosaccharide were prepared from corresponding herb. Adult male Wistar rats were randomly divided into four groups of 10 each, as follows: group 1, healthy control rats given only sterile normal saline; group 2, diabetic control rats received sterile normal saline; group 3, diabetic rats treated with crude extract of Rosa canina (40% w/v) by oral gavage for 8 weeks; group 4, diabetic rats treated with purified oligosaccharide of Rosa canina (2 mg/kg) by oral gavage for 8 weeks. After treatment, body weight, fasting blood glucose, serum insulin levels and islet beta-cell repair and proliferation were investigated. The possible cytoprotective action of oligosaccharide was evaluated in vitro. The effect of oligosaccharide on apoptosis and insulin secretion in cell culture media were examined. Real-time PCR was used to determine the expression level of some glucose metabolism-related regulator genes. Findings / Results: In the animal model of diabetes, the insulin levels were increased significantly due to the regeneration of beta-cells in the islands of langerhans by the purified oligosaccharide. In vitro cell apoptosis examination showed that high concentration of oligosaccharide increased cell death, while at low concentration protected cells from streptozotocin-induced apoptosis. Molecular study showed that the expression of Ins1 and Pdx1 insulin production genes were increased, leading to increased expression of insulin-dependent genes such as Gck and Ptp1b. On the other hand, the expression of the Slc2a2 gene, which is related to the glucose transporter 2, was significantly reduced due to insulin concentrations. Conclusion and implications: The purified oligosaccharide from Rosa canina was a reliable anti-diabetic agent, which acted by increasing insulin production in beta-cells of the islands of Langerhans.

Profiles Drug Subst Excip Relat Methodol. 2020;45:119-157 Authors: Khalil NY, Darwish IA, Al-Qahtani AA Abstract Isotretinoin is chemically named as: (2Z, 4E, 6E, 8E)-3,7-Dimethyl-9-(2,6,6-trimethylcyclohex-1-enyl)nona-2,4,6,8-tetraenoic acid. It is an orally active retinoic acid derivative for the treatment of severe refractory nodulocystic acne. It acts primarily by reducing sebaceous gland size and sebum production, and as a result alters skin surface lipid composition. Using isotretinoin for 1-2mg/kg/day for 3-4 months produces 60%-95% clearance of inflammatory lesions in patients with acne. Doses as low as 0.1mg/kg/day have also proven successful in the clearance of lesions. Encouraging results have also been seen in small numbers of patients with rosacea, Side effects affecting the mucocutaneous system and raised serum triglyceride levels occur in most patients receiving isotretinoin. Isotretinoin is strictly contraindicated in women of childbearing potential. This profile discusses and explains names of isotretinoin, its physical and chemical characteristics. It also includes methods of preparation, thermal and spectral behavior, methods of analysis, and pharmacology. PMID: 32164966 [PubMed - in process] {url} = URL to article
  14. Related Articles Fatty acid profile and in vitro biological properties of two Rosacea species (Pyrus glabra and Pyrus syriaca), grown as wild in Iran. Food Sci Nutr. 2020 Feb;8(2):841-848 Authors: Hazrati S, Govahi M, Mollaei S Abstract The high demands for the consumption of edible oils have caused scientists to struggle in assessing wild plants as a new source of seed oils. Therefore, in this study, the oil yield, fatty acid and tocopherol compositions, antioxidant and antibacterial activities of the oils obtained from Iran's two endemic plants (Pyrus glabra and Pyrus syriaca) were investigated. The obtained oil yields from the P. glabra and P. syriaca seeds were 33 ± 0.51 and 26 ± 0.28 w/w%, respectively. Oleic acid (C18:1) with the amount of 49.51 ± 1.05% was the major fatty acid in the P. glabra oil, while the main fatty acids in the P. syriaca seed oil belonged to linoleic acid (C18:2) and oleic acid (C18:1) with the amounts of 46.99 ± 0.37 and 41.43 ± 0.23%, respectively. The analysis of tocopherols was done by HPLC, and the results indicated that the P. glabra and P. syriaca seed oils were rich in α-tocopherol (69.80 ± 1.91 and 45.50 ± 1.86 mg/100 g oil, respectively), constituting 86.24 and 89.01% of total detected tocopherols, respectively. The study on the reducing capacity of the oils indicated that the P. glabra oil had more reducing capacity than the P. syriaca oil. Moreover, the antioxidant activity of the P. glabra seed oil (43.4 ± 0.7 µg/ml) was higher than the P. syriaca seed oil (46.3 ± 1.2 µg/ml). Also, the investigation of the antibacterial activities indicated that the P. glabra and P. syriaca oils have an inhibitory effect on the studied bacteria. The results indicate that the oils of these plants can be appropriate sources of plant oils which can act as natural antibacterial agents. PMID: 32148793 [PubMed] {url} = URL to article
