  1. Related Articles Rosacea treatment guideline for The Netherlands. Br J Dermatol. 2020 Jan 23;: Authors: van Zuuren EJ, van der Linden MMD, Arents BWM Abstract The classification of rosacea has evolved from a subtyping into a phenotype approach1-3 and an updated systematic review on interventions in rosacea using this approach was recently published.4 Therefore, we developed a new evidence-based guideline for all physicians and skin therapists involved in the management of patients suffering from rosacea. A patient information leaflet based on this guideline was produced. The Working Group (WG) consisted of dermatologists (4), general practitioner (1), ophthalmologist (1), plastic surgeon (1), skin therapists (2), patient (1) and staff members of the Dutch Society of Dermatology and Venereology (2). All affiliated organizations participated in external review. PMID: 31970753 [PubMed - as supplied by publisher] {url} = URL to article
  2. Related Articles First reported cases of Actinic folliculitis treated successfully with topical retinoid. Clin Exp Dermatol. 2020 Jan 22;: Authors: Rahman S, Powell J, Al-Ismail D Abstract Actinic Folliculitis (AF) is a rare recurrent seasonal photodermatosis, relatively newly characterised by non pruritic, monomorphic pustules and papules appearing 4 - 24 hours after exposure to sunlight. Lesions usually affect the face but also appear on the upper chest and arms. Resolution normally occurs within 7 - 10 days with cessation of sunlight exposure. AF is resistant to standard treatments used for acne vulgaris and acne rosacea with only oral retinoids previously being reported as effective. We report the first 2 cases of actinic folliculitis responding extremely effectively to a topical retinoid. PMID: 31965609 [PubMed - as supplied by publisher] {url} = URL to article
  3. Related Articles Off-label Uses of Topical Pimecrolimus. J Cutan Med Surg. 2019 Jul/Aug;23(4):442-448 Authors: Ladda M, Sandhu V, Ighani A, Yeung J Abstract Pimecrolimus is a topical calcineurin inhibitor currently approved for second-line use in the management of mild-to-moderate atopic dermatitis in patients age 2 years and older. Given the safety profile and nonsteroidal mechanism of pimecrolimus, there has been significant interest in its use in the treatment of a variety of dermatological conditions. This article reviews research that has been published on the off-label uses of topical pimecrolimus, with a focus on published RCTs. Convincing evidence exists supporting pimecrolimus' efficacy in oral lichen planus and seborrheic dermatitis. For other conditions studied to date, pimecrolimus may prove to be a useful treatment alternative when conventional agents fail. Adverse events seen with its off-label use were typically application site reactions, the most common being a transient burning sensation. In summary, pimecrolimus appears to be an effective agent in the treatment of multiple dermatological conditions and may be worth considering as a pharmacologic alternative in several conditions when first-line treatment fails, or for areas that are more susceptible to the adverse effects of topical corticosteroids.

  4. Related Articles Anticancer effect of Amygdalin (vitamin B17) on hepatocellular carcinoma cell line(HepG2) in the presence and absence of Zinc. Anticancer Agents Med Chem. 2020 Jan 19;: Authors: El-Desouky MA, Fahmi AA, Abdelkader IY, Nasraldin KM Abstract BACKGROUND: Amygdalin (Vitamin B-17) is a naturally occurring vitamin found in the seeds of the fruits of Prunus Rosacea family including apricot, bitter almond, cherry, and peach. OBJECTIVE: The purpose of this study was to examine the effect of amygdalin with and without zinc on hepatocellular carcinoma (HepG2) cell line. METHODS: MTT assay was used to evaluate the cytotoxicity of amygdalin without zinc, amygdalin + 20µmol zinc, and amygdalin + 800µmol zinc on HepG2 cell lines. The cell cycle distribution assay was determined by flow cytometry. Apoptosis was confirmed by Annexin V-FITC/PI staining assay. Moreover, the pathway of apoptosis was determined by the percentage of change in the mean levels of P53, Bcl2, Bax, cytochrome c, and caspase-3. RESULTS: Amygdalin without zinc showed a strong anti-HepG2 activity. Furthermore, HepG2 cell lines treatment with amygdalin + 20µmol zinc and amygdalin + 800µmol zinc showed a highly significant apoptotic effect than the effect of amygdalin without zinc. Amygdalin treatment induced the cell cycle arrest at G2/M and increased the levels of P53, Bax, cytochrome c, and caspase-3 significantly, while it decreased the level of anti-apoptotic Bcl2. CONCLUSION: Amygdalin is a natural anti-cancer agent which can be used for the treatment of hepatocellular carcinoma. It promotes apoptosis via the intrinsic cell death pathway (the mitochondria-initiated pathway) and cell cycle arrest at G/M. The potency of amygdalin in HepG2 treatment increased significantly by the addition of zinc. PMID: 31958042 [PubMed - as supplied by publisher] {url} = URL to article
  5. Related Articles Myositis Induced by Isotretinoin: A Case Report and Literature Review. Am J Case Rep. 2020 Jan 20;21:e917801 Authors: Rivillas JA, Santos Andrade VA, Hormaza-Jaramillo AA Abstract BACKGROUND Retinoid-induced myositis is a rare condition encountered in clinical practice. Its occurrence implies a diagnostic challenge due to the multiple causes associated with myopathic syndromes. The most common clinical presentation is generalized affection. Focal myositis is even less frequent and easily misdiagnosed as muscular disease of other etiology. CASE REPORT We describe a case of 45-year-old male with a history of nephrolithiasis and rosacea diagnosed by dermatology, who was management with isotretinoin 1 mg/kg per day in 2 doses with clinical improvement. Later, he presents muscle pain in the upper limbs with marked functional limitation associated by choluria, without muscular pains in other location; he had no history of using another medication. At his physical examination, vital signs were normal, with edema and pain in the bilateral bicipital region associated with limitation for flexion-extension of shoulders and elbows and high levels of creatine phosphokinase (CPK). He was transferred to the intensive care unit where he received fluid therapy because of the high risk of deterioration of renal function, very high CPK levels, and a history of obstructive uropathy. One year after this hospitalization, the cutaneous symptoms worsened and the patient voluntarily restarted isotretinoin and 5 months later he presented again with the same symptoms of the first episode. CONCLUSIONS Drug-induced myositis should be taken into consideration in the differential diagnosis of myopathic syndromes. Retinoids have the potential to cause varying degrees of myositis and their rapid identification could prevent major complications. PMID: 31958335 [PubMed - in process] {url} = URL to article
  6. Related Articles Characterization and Analysis of the Skin Microbiota in Rosacea: Impact of Systemic Antibiotics. J Clin Med. 2020 Jan 09;9(1): Authors: Woo YR, Lee SH, Cho SH, Lee JD, Kim HS Abstract Systemic antibiotics are extensively used to control the papules and pustules of rosacea. Hence, it is crucial to understand their impact on the rosacea skin microbiota which is thought to be perturbed. The purpose of this study was to compare the makeup and diversity of the skin microbiota in rosacea before and after taking oral antibiotics. We also compared the skin microbiota at baseline according to age and rosacea severity. A longitudinal cohort study was performed on 12 rosacea patients with papules/pustules and no recent use of oral and topical antimicrobials/retinoids. Patients were prescribed oral doxycycline, 100 mg, twice daily for six weeks. Skin areas on the cheek and nose were sampled for 16S ribosomal RNA gene sequencing at baseline, and after six weeks of doxycycline treatment. Eleven females and one male aged 20-79 (median 51) with a median Investigator's Global Assessment score of 3 (moderate) were enrolled. At baseline, Staphylococcus epidermidis was the most dominant species followed by Cutibacterium acnes (formerly Propionibacterium acnes). In the 60 Over-age group, the prevalence of Cutibacterium acnes was lower than that of the 60 & Under-age group. Rosacea severity increased with age and was associated with a decrease in the relative abundance of Cutibacterium acnes and an increase of Snodgrassella alvi. Across all subjects, antibiotic treatment reduced clinical rosacea grades and was associated with an increase in the relative abundance of Weissella confusa (P = 0.008, 95% CI 0.13% to 0.61%). Bacterial diversity (alpha diversity) was not significantly altered by antibiotics treatment. Principal coordinates analysis showed mild clustering of samples by patient (ANOSIM, Analysis of Similarity, R = 0.119, P = 0.16) and scant clustering with treatment (ANOSIM, R = 0.002; P = 0.5). In conclusion, we believe that rosacea has a unique age-dependent characteristic (i.e., severity). Although we were not able to pinpoint a causative microbiota, our study provides a glimpse into the skin microbiota in rosacea and its modulation by systemic antibiotics.

Clin Exp Dermatol. 2020 Jan 10;: Authors: Salerni G, Peralta R, Bertaina C, Gorosito M, Fernández-Bussy R Abstract Idiopathic facial aseptic granuloma (IFAG) is an uncommon childhood condition, characterized by one or more asymptomatic erythematous-violaceous nodules, usually located on the cheeks and eyelid [1]. IFAG heals spontaneously usually without scarring after a few months to a year. The pathogenesis of this disease is unclear; the most current hypothesis is that represents a form of paediatric rosacea [2]. PMID: 31919863 [PubMed - as supplied by publisher] {url} = URL to article
  10. Hydroxychloroquine is a novel therapeutic approach for rosacea. Int Immunopharmacol. 2020 Jan 06;79:106178 Authors: Li J, Yuan X, Tang Y, Wang B, Deng Z, Huang Y, Liu F, Zhao Z, Zhang Y Abstract Rosacea is a chronic inflammatory disease in face. Hydroxychloroquine (HCQ), an anti-malaria drug, was reported to have anti-inflammation activities. However, the role of HCQ on rosacea remains unclear. In this study, we revealed the potential molecular mechanism by which HCQ improved rosacea in rosacea-like mice and mast cells (MCs). Moreover, the effects of HCQ treatment for rosacea patients were investigated. In this study, we found HCQ ameliorated the rosacea-like phenotype and MCs infiltration. The elevated pro-inflammatory factors and mast cell protease were significantly inhibited by HCQ treatment in rosacea-like mice. In vitro, HCQ suppresses LL37-induced MCs activation in vitro, including the release of inflammatory factors, chemotaxis, degranulation and calcium influx. Moreover, HCQ attenuated LL37-mediated MCs activation partly via inhibiting KCa3.1-mediated calcium signaling. Thus, these evidences suggest HCQ ameliorated rosacea-like dermatitis may be by regulating immune response of MCs. Finally, the 8-week HCQ treatment exerted satisfactory therapeutic effects on erythema and inflammatory lesions of rosacea patients, indicating that it is a promising drug for rosacea in clinical treatment.

  12. A Multicenter, Randomized, Double-Masked, Parallel Group, Vehicle-Controlled Phase 2b Study to evaluate the safety and efficacy of 1% and 3% topical Minocycline Gel in patients with Papulopustular Rosacea. Br J Dermatol. 2020 Jan 06;: Authors: Webster G, Draelos ZD, Graber E, Lee MS, Dhawan S, Salman M, Magrath GN Abstract BACKGROUND: Papulopustular rosacea is characterized by chronic facial erythema and inflammatory facial lesions. Minocycline has anti-inflammatory properties which may be effective in the treatment of rosacea inflammatory lesions. OBJECTIVE: To assess the safety and efficacy of once-daily Minocycline Gel 1% and 3% in subjects with papulopustular rosacea. METHODS: This was a prospective, double-blinded study conducted at 26 sites in the United States. Subjects with papulopustular rosacea and between 12 and 40 inflammatory lesions were randomized to either 1% minocycline, 3% minocycline, or vehicle. The study product was applied to the face at bedtime for 12 weeks. The primary endpoints was the mean change in inflammatory lesions at week 12. Key secondary endpoints included success on the investigator global assessments (IGA). RESULTS: 270 subjects were randomized. The baseline mean lesion count was 24.6, 25.1, and 24.3 in the 1% minocycline, 3% minocycline, and vehicle groups, respectively. At week 12, mean inflammatory lesion count had decreased by 12.64 (1% minocycline), 13.09 (3% minocycline), and 7.92 (vehicle). The minocycline treatment arms significantly decreased inflammatory lesions when compared to vehicle (p=0.01, 95% CI -7.930 to -0.871 for 1% minocycline and p=0.007, 95% CI -8.319 to -1.310 for 3% minocycline). The proportion of subjects achieving IGA success was 38.9% in the 1% minocycline group (p=0.34, OR 1.396 and OR 95% CI 0.708 to 2.751 vs. vehicle), 46.2% in the 3% minocycline group (p=0.04, OR 2.028 and OR 95% CI 1.040 to 3.952 vs. vehicle), and 30.8% in the vehicle group. CONCLUSION: 1% and 3% topical minocycline gel appears safe and tolerable. 1% and 3% topical minocycline gel significantly decreased inflammatory lesion counts and a significantly larger proportion of subjects achieved IGA success at week 12 in the 3% topical minocycline group. These findings support further evaluation of minocycline gel for the treatment of inflammatory lesions associated with papulopustular rosacea.

  14. Related Articles Bardolph's rosacea: skin disorders that define personality in Shakespeare's plays. Clin Dermatol. 2019 Sep - Oct;37(5):600-603 Authors: Hassan S, Mohammed TO, Hoenig LJ Abstract Several popular Shakespearean characters are dramatically portrayed on stage with striking physical appearances caused by medical and dermatologic disorders. Shakespeare's colorful portrayal of their maladies not only helps to entertain audiences but also serves to define the characters' personalities and behavior. Shakespeare himself emphasizes this point in his play Richard III, in which the notorious English king states that his evil nature is a direct result of his hideous spinal deformity. This contribution discusses four other famous Shakespearean characters: Bardolph, who appears to be suffering from rosacea; the Witches of Macbeth, who have beards; Juliet, who has green sickness (chlorosis); and Falstaff, who is morbidly obese. In all of these cases, their skin disorders and medical maladies serve to highlight their underlying nature. PMID: 31896414 [PubMed - in process] {url} = URL to article

  17. Anthocyanin-Functionalized Contact Lens Sensors for Ocular pH Monitoring. ACS Omega. 2019 Dec 24;4(26):21792-21798 Authors: Riaz RS, Elsherif M, Moreddu R, Rashid I, Hassan MU, Yetisen AK, Butt H Abstract Anthocyanins are bioactive compounds naturally found in a variety of leaves, fruits, and vegetables. Anthocyanin pigments undergo a modification in their chemical structure when exposed to different concentrations of hydrogen ions, and they were extensively studied to be used as active elements in biocompatible pH sensors. The ocular pH is a significant parameter to assess the ocular physiology in cases of postocular surgery, keratoconjunctivitis, and ocular rosacea. Contact lenses have the potential to be used as medical diagnostic devices for in situ continuous monitoring of the ocular physiology. Here, anthocyanin-functionalized contact lenses were developed as wearable sensors to monitor the ocular pH. Anthocyanin pigments were extracted from Brassica oleracea and used to functionalize the polymeric matrices of commercial soft contact lenses by soaking and drop-casting processes. Contact lenses responded to the physiological ocular pH of 6.5, 7.0, and 7.5, exhibiting a systematic color shift from pink (pH 6.5) to purple (pH 7.0) and blue (pH 7.5). The functionalization of contact lens sensors was evaluated as a function of the dye concentration. Quantitative values were obtained by comparing the RGB triplets of the colors obtained with the naturally extracted dye and with delphinidin chloride dye in 0.0 to 1.5 mmol L-1 aqueous solution. The functionalization of contact lenses was studied as a function of the soaking time, resulting in best results when soaking for 24 h. The dye leakage from the contact lenses in deionized water was evaluated, and a negligible leakage after 18 h was observed. Poly-2-hydroxy ethylmethacrylate contact lenses were fabricated and cross-linked with anthocyanin dye, resulting in a slight color shift upon pH changes from 6.5 to 7.4. Contact lens pH sensors may be used to continuously monitor the ocular pH at point-of-care settings. PMID: 31891056 [PubMed] {url} = URL to article
  18. Related Articles Microdebrider-Assisted Rhinophyma Excision. Case Rep Otolaryngol. 2019;2019:4915416 Authors: Abushaala A, Stavrakas M, Khalil H Abstract Rhinophyma represents a progressive deformity of the nose which leads to cosmetic disfigurement and has a significant impact on the patient's quality of life. This pathological entity originates from hyperplasia of sebaceous gland tissue, connective tissue, and vessels of the nose and is associated with rosacea and more specifically, stage III rosacea. Surgical treatment is the method of choice. We present five cases of rhinophyma that we treated with microdebrider-assisted excision. The procedure was divided in two main steps: scalpel excision of the main bulk of the rhinophyma and then further contouring with the microdebrider. All patients had weekly follow-up for the first four weeks, and then three-monthly. All patients had uneventful recovery and satisfactory cosmetic outcomes. No postoperative infections or other complications were reported in our case series. The use of the microdebrider reduces the operating time, preserves the islands of skin regeneration, and allows finer manipulations than the standard scalpel techniques. Microdebrider-assisted rhinophyma excision is a safe approach, with good aesthetic results. Larger series of patients need to be examined in order to establish the value of the method.

  20. Related Articles Demodex Infestation in Patients with Rosacea Turkiye Parazitol Derg. 2019 Dec 23;43(4):194-197 Authors: Türkmen D, Türkoğlu G Abstract Objective: Although the etiology of rosacea is not known exactly, it is thought as a multifactorial disease. Demodex spp. are asymptomatic saprophytic ectoparasites living in hair follicles and sebaceous glands. The aim of this study was to investigate the frequency of Demodex spp. in patients with rosacea and compare with the control group by using superficial skin biopsy method. Methods: Seventy seven patients with rosacea and 31 control patients were included in the study. In patients, for the determination of density of Demodex spp., non-invasive standard superficial skin biopsy method was applied. Detection of ≥5/cm2 Demodex spp. was considered positive. Results: The mean age of the patients was 44.5±14.6 years and the mean age of the control group was 48.2±14.9 years. Of the patients, 55.1% had erythema-telangiectatic type, 43.5% had papulopustular type, and 3.9% had fimatous type lesions. Demodex infestation was positive in 33.8% of the patients with rosacea and this rate was 9.7% in the control group. Difference was statistically significant. There was no significant difference in Demodex spp. positivity in terms of gender in patients with rosacea. Conclusion: The importance of Demodex infestation in patients with rosacea has been increasing in recent years. Considering some studies conducted in our country, we think that the investigation of Demodex spp. in patients who are considered to have rosacea will be beneficial in the terms of early diagnosis and treatment.

  21. Related Articles Is rosacea a systemic disease? Clin Dermatol. 2019 Nov - Dec;37(6):629-635 Authors: Wollina U Abstract Rosacea is a chronic inflammatory facial disease occurring world-wide. The incidence of rosacea is increasing with age, with the clinical course being characterized by relapses. The pathogenesis of rosacea is not completely understood, but neurovascular and immunologic mechanisms are involved. Rosacea has a number of known extrinsic triggers that should be avoided, such as sun exposure, heat and cold, alcoholic beverages, and spicy food. Of greater importance is the observation that rosacea may develop as a manifestation of systemic diseases with a significant morbidity and even mortality. Obesity, Helicobacter pylori infection, smoking, and inflammatory bowel disease bear a significant risk for the development of rosacea. Metabolic, psychiatric, and neurologic disorders and certain types of cancer show a significant association with rosacea. The possible link to cardiovascular events is debatable. There are extrafacial and extracutaneous manifestations of rosacea, such as the red scalp syndrome, ocular rosacea, and migraine. Rosacea should be considered a systemic disease.

  22. Related Articles Efficacy of topical ivermectin and impact on quality of life in patients with papulopustular rosacea: A systematic review and meta-analysis. Dermatol Ther. 2019 Dec 20;:e13203 Authors: Husein-ElAhmed H, Steinhoff M Abstract Rosacea is a chronic inflammatory dermatosis involving certain facial areas. The multifactorial nature of this condition makes the management challenging. In addition, rosacea affects negatively to patients' quality of life (QoL). Despite the multiple articles supporting its use for papulopustular rosacea (PPR), there is a shortage of high-quality evidence researches comparing the efficacy of ivermectin cream (IVM) 1% with other available topical choices. Besides, the well-documented impaired of self-esteem and stigmatization of rosacea patients make essential to address which treatment can provide the greatest psychological, physical and social benefit. The objective of this work is to critically review and appraise the efficacy of topical IVM 1% in PPR and the impact in patients' QoL against other options. We carried out a search of literature from PubMed, MEDLINE, EMBASE, Cochrane and clinicaltrials.gov using the following descriptors: "rosacea" AND "ivermectin". Efficacy was assessed with the Investigator Global Assessment (IGA), and the impact on QoL was based on the DLQI score Six studies from 4 published articles were included. The meta-analysis estimated that more participants achieved "success" (IGA≤1) and "complete clearance" (IGA = 0) with IVM 1%. The overall effect estimate for IGA≤1 was: 1.56 [1.23-1.97], while for IGA = 0 it was: 1.72 [1.40-2.11]. The rate of participants achieving lower DLQI score, and thus, better QoL was higher with IVM 1%. The overall effect estimate was: 1.71 [1.34-2.18] at week 16# and 1.64 [1.38-1.94] at week 52#. This meta-analysis gives strong evidence that IVM 1% cream is the most effective topical treatment above other alternatives and it satisfies the impairment of social and working life with a sustained better QoL. Further studies confirming and extending this period of remission are warranted, as well as researches investigating the potential use of this agent in combination with other agents.

  24. Related Articles Ros-NET: A deep convolutional neural network for automatic identification of rosacea lesions. Skin Res Technol. 2019 Dec 17;: Authors: Binol H, Plotner A, Sopkovich J, Kaffenberger B, Niazi MKK, Gurcan MN Abstract BACKGROUND: Rosacea is one of the most common cutaneous disorder characterized primarily by facial flushing, erythema, papules, pustules, telangiectases, and nasal swelling. Diagnosis of rosacea is principally done by a physical examination and a consistent patient history. However, qualitative human assessment is often subjective and suffers from a relatively high intra- and inter-observer variability in evaluating patient outcomes. MATERIALS AND METHODS: To overcome these problems, we propose a quantitative and reproducible computer-aided diagnosis system, Ros-NET, which integrates information from different image scales and resolutions in order to identify rosacea lesions. This involves adaption of Inception-ResNet-v2 and ResNet-101 to extract rosacea features from facial images. Additionally, we propose to refine the detection results by means of facial-landmarks-based zones (ie, anthropometric landmarks) as regions of interest (ROI), which focus on typical areas of rosacea occurrence on a face. RESULTS: Using a leave-one-patient-out cross-validation scheme, the weighted average Dice coefficients, in percentages, across all patients (N = 41) with 256 × 256 image patches are 89.8 ± 2.6% and 87.8 ± 2.4% with Inception-ResNet-v2 and ResNet-101, respectively. CONCLUSION: The findings from this study support that pre-trained networks trained via transfer learning can be beneficial in identifying rosacea lesions. Our future work will involve expanding the work to a larger database of cases with varying degrees of disease characteristics.
