    Acne scarring can be classified into atrophic icepick, boxcar, and rolling scars in addition to keloidal and hypertrophic scars. Additionally, these scars can be erythematous, hyperpigmented, and/or hypopigmented. Each scar type has a different structural cause warranting a customized approach. Many cosmetic options exist to address these changes individually, but little literature exists about the safety and efficacy of combining such procedures and devices. A Medline search was performed on combination treatments because it relates to facial acne scarring, and results are summarized. Practical applications for these combinations of procedures are also discussed. Studies examining the efficacy and safety of ablative, nonablative, fractionated, and nonfractionated lasers, dermabrasion, chemical peels, needling, subcision, radiofrequency, stem cell therapy, fat transplantation, platelet-rich plasma, and hyaluronic acid dermal fillers for acne scars were found. The authors review their experience in combining these techniques. Review of the literature revealed multiple single options for facial acne scarring treatment with minimal evidence in the literature found on the safety and efficacy of combining such procedures and devices. The authors' experience is that combining acne scar treatment techniques can be performed safely and synergistically with optimal patient outcomes.

    Cosmetic products contribute to the efficacy of anti-acneic treatment. Cleaning bars without soap and lotions are to be preferred to soaps. Morning application of moisturizing creams compensate for dryness and irritation induced by topical treatment. Some of these cosmetic products may have a limited efficacy of the shiny appearance and/or acne lesions. Scrubs, abrasive sponges, masks and patches have a very limited usefulness. Make up and camouflage techniques are authorized, provided that the products have been tested non comedogenic and non acne-genic.

    Full Text Available Acne is a chronic disorder of pilosebaceous unit clinically characterized by comedones, papules, pustules, nodules and scarring. It affects almost 85% of young people between 12-24 years of age. Four main pathophysiologic factors that influence the development of acne are; increased sebum secretion, abnormal follicular desquamation, P. acnes colonization of the follicle and inflammation. The treatment of acne includes; topical retinoids, topical antimicrobial agents, systemic antibiotics, hormonal therapy and oral isotretinoin. Topical retinoids should be used as the first choice in comedonal acne, in combination with topical and/or systemic antimicrobials for mild to moderate inflammatory acne and as maintenance therapy once clearance has been achieved. Topical and systemic antibiotics which are used to treat moderate inflammatory acne should not be used as monotherapy but combined with topical benzoyl peroxide or topical retinoids and should be stopped as soon as possible. Hormonal therapy is an excellent choice for women, especially if oral contraception is desired. It may also be used for female patients with severe seborrhea, late onset acne and with proven hyperandrogenism. Oral isotretinoin targets all pathophysiologic factors in acne and is the mainstay of therapy for severe acne. It has to be kept in mind that the management of acne and compliance of the patient to the treatment can be enhanced by a number of general strategies such as education about acne and treatment, skin care, diet and adjuvant procedures.

    Objective: This study evaluated the safety and efficacy of sublative fractional bipolar radiofrequency and bipolar radio frequency combined with diode laser for the treatment of both superficial and deep acne scars in patients with skin types II to V. Design: Prospective, single-center study. Subjects received up to five treatments with sublative fractional bipolar radiofrequency and bipolar radiofrequency combined with diode laser. Treatments were directed to at least two facial (forehead, perioral, cheeks) and/or neck areas with acne scars at four-week intervals. Treatment parameters on each subject were based on skin type and on skin responses to test spots on the target area just before treatment. Setting: Physician office. Participants: Subjects (n=20, aged 40.7±10.5 years [mean ± SD], skin types II–V) with acne scars and without acne lesions enrolled in this prospective study. Measurements: Results were evaluated just before each treatment and at four and 12 weeks after the final treatment using the Goodman Scar Scale, a quantitative method of evaluating scars that attempts to reduce grading subjectivity, as well as by patient satisfaction. Results: Acne scars improved significantly one month after three treatments and improvement persisted for at least 12 weeks after the fifth treatment. Improvement was not affected by skin type. Adverse effects were limited to transient erythema and edema. Conclusion: The combination of diode laser and bipolar radiofrequency energy device in addition to fractionated sublative radiofrequency is a safe and statistically significantly effective combined modality for the treatment of both superficial and deep acne scars in patients with skin types II to V with minimal downtime and no significant side effects.

This type was predominant in all PMH lesions (73.9% of reads in average) but only detected as a minor proportion in matching control samples of healthy individuals (14.2% of reads in average). Strikingly......, successful PMH treatment is able to alter the composition of the P. acnes population by substantially diminishing the proportion of P. acnes type III. Our study suggests that P. acnes type III may play a role in the formation of PMH. Furthermore, it sheds light on substantial differences in the P. acnes...

    Acne vulgaris, one of the most commonly encountered conditions in dermatology, affects individuals in all racial and ethnic groups, yet clinical presentation varies among different skin types. Acne, particularly when it is severe, may significantly impact an individual's quality of life and psychological well-being. Potential sequelae, such as postinflammatory hyperpigmentation and keloid scarring, occur more frequently in individuals with skin of color and may be long lasting or permanent. Acknowledging the potentially long-term physical and emotional scars caused by acne vulgaris, attention has focused on management strategies that limit the disease to an early stage. Early and efficacious treatment of acne in skin of color patients may minimize pigmentary abnormalities and keloid scarring. By recognizing racial and ethnic differences in clinical presentation and potential sequelae, treatment regimens may be tailored to ensure favorable outcomes for patients of all skin types.

    Achieving an effective management of acne vulgaris with minimal complications remains a difficult challenge for physicians. Moreover, the rise in antibiotic-resistant strains reduce the future usefulness of current mainstay therapies, and accordingly, the need for alternative therapies is mandatory. Phototherapy has been shown to be an effective treatment for acne, and there has been a renewed interest in photodynamic therapy as a treatment modality for this condition. To evaluate the effectiveness of pulsed dye laser (PDL), intense pulsed light (IPL) and light-emitting diode (LED) phototherapy for the treatment of moderate to severe acne vulgaris. Forty-five patients with moderate to severe acne were randomly divided into 3 equal groups. Group 1 was treated with a PDL, group 2 was treated with IPL, and group 3 was treated with a blue-red combination LED. Treatment was continued until a > or = 90% clearance of patient lesions was achieved. Clinical assessments were conducted before starting treatment, at 1 month as a midpoint evaluation, and after the final treatment session. Patients treated with the PDL reached a > or = 90% clearance of their inflammatory lesions after a mean of 4.1 +/- 1.39 sessions, while patients treated with IPL required a mean of 6 +/- 2.05 sessions. Patients treated with the LED required a mean of 10 +/- 3.34 sessions. At the mid-point evaluation, the percent reduction in acne lesions treated with the PDL was 90% or more, in cases of IPL and the LED, the percent reductions were 41.7% and 35.3%, respectively. Laser and light phototherapy sessions were well tolerated with minimal adverse events experienced as being mild and usually self-limiting. The encouraging results of the present study contributes evidence of phototherapy as useful therapeutic option for treatment of moderate to severe acne, and validates further studies to evaluate treatments with a larger number of patients and for a longer period of follow-up.

Recognizing solutions to nonadherence is critical. Objective: The purpose of this study is to describe the hurdles associated with acne nonadherence and to provide mechanisms on how to ameliorate them. Methods: PubMed database was searched. Of the 419 search results, 29 articles were reviewed to identify hurdles to adherence and corresponding solutions. Results: Hurdles to primary nonadherence where the medication is not even started, include lack of knowledge, confusion about usage, weak physician–patient relationship, fear of adverse reactions, and cost. Secondary nonadherence hurdles where the medication is started but is not taken as directed include lack of results, complex regimens, side effects, busy lifestyle, forgetfulness, inconvenience, and psychiatric comorbidity. Solutions to these hurdles include treatment simplification, technology, and dynamic education. Limitations: Adherence is affected by numerous factors, but available literature analyzing acne adherence and interventions to improve adherence to treatment is limited. Conclusion: There are several hurdles in adhering to acne treatment. Recognition of these hurdles and finding appropriate solutions may be as important to treatment outcomes as choosing the right medication to prescribe.

    For many years the positive effect of hydrocolloid dressings on skin-related conditions attracted the attention of the medical scientific community. The use of Acne Dressing, a tape of hydrocolloid dressing, for the treatment of acne has not been reported previously. The aim of this study was to evaluate the clinical efficacy and beneficial effect of Acne Dressing on the marker for sebum output evaluations. We also determined the cosmetic outcome of this application during the treatment of acne and whether the material could prevent hand touching and UVB light from reaching the skin surface. The objective of this study was to assess improvement in acne vulgaris and tolerability during one week of short contact treatment with Acne Dressing compared to skin tapes. Efficacy data specific to treatment of acne vulgaris with Acne Dressing (3M Health Care) from a double-blind, randomized, skin types-controlled study is reported. A total of 20 patients with mild-to-moderate acne vulgaris applied the skin tapes or Acne Dressing every two days for up to one week. Twenty patients were enrolled in this study: ten patients received Acne Dressing and ten patients received skin tapes. Both groups showed decreases from baseline to the end of treatment in the mean of the overall severity scale (decrease of 1.37 from 1.8 to 0.43 with Acne Dressing and 0.28 from 1.08 to 0.8 with skin tapes). A statistically significant greater reduction was observed over a period of three to seven days in the overall severity of acne and inflammation in the Acne Dressing group compared with the mono-therapy (skin tapes) group. Similarly, Acne Dressing resulted in a significantly greater improvement in the redness, oiliness, dark pigmentation, and sebum casual level at days 3, 5, and 7. The ratio of transmission of UVB light with Acne Dressing was 7.4%, and 38% with skin tapes, which shows less UVB light reaching the skin surface with the Acne Dressing.

    Acne is a chronic inflammatory disease whose psychosocial effects can greatly impair quality of life. Various scales are used to classify the severity of acne, and several treatment algorithms are currently applied: no consensus on a common scale or treatment guidelines has been reached. A group of Spanish experts therefore met to identify a scale the majority could accept as the most appropriate for classifying severity and treating accordingly. The group chose the following classifications: comedonal acne, mild or moderate papulopustular acne, severe papulopustular acne, moderate nodular acne, and nodular-cystic acne (or acne tending to leave scars). Consensus was reached on first- and second-choice treatments for each type and on maintenance treatment. The experts also issued specific recommendations on antibiotic use (starting with mild or moderate papulopustular acne), always in combination with retinoids and/or benzoyl peroxide. The use of isotretinoin (starting at severe papulopustular or moderate nodular acne) was also covered. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

    Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Some studies have reported an association between serum zinc levels and acne vulgaris. We aimed to evaluate the serum zinc level in patients with acne vulgaris and compare it with healthy controls. One hundred patients with acne vulgaris and 100 healthy controls were referred to our clinic. Acne severity was classified according to Global Acne Grading System (GAGS). Atomic absorption spectrophotometry was used to measure serum zinc levels. Mean serum level of zinc in acne patients and controls was 81.31 ± 17.63 μg/dl and 82.63 ± 17.49 μg/dl, respectively. Although the mean serum zinc level was lower in acne group, it was not statistically significant (P = 0.598). There was a correlation between serum zinc levels with severity and type of acne lesions. The results of our study suggest that zinc levels may be related to the severity and type of acne lesions in patients with acne vulgaris. Relative decrease of serum zinc level in acne patients suggests a role for zinc in the pathogenesis of acne vulgaris.

    Full Text Available Background: Various treatment modalities including non-invasive methods such as chemical peels, topical retinoids, microdermabrasion, minimally invasive techniques such as microneedling, fractional lasers, microneedling radiofrequency devices and invasive procedures such as acne scar surgeries and ablative lasers are used for acne scars, each with its own unique advantages and disadvantages. This study is a retrospective assessment of efficacy and safety of microneedling fractional radiofrequency in the treatment of acne scars. Methods: Thirty one patients of skin types III-V with moderate and severe facial acne scarring received four sequential fractional radiofrequency treatments over a period of 6 months with an interval of 6 weeks between each session. Goodman & Baron′s acne scar grading system was used for assessment by a side by side comparison of preoperative and post- operative photographs taken at their first visit and at the end of 3 months after the last session. Results: Estimation of improvement with Goodman and Baron′s Global Acne Scarring System showed that by qualitative assessment of 31 patients with grade 3 and grade 4 acne scars, 80.64% showed improvement by 2 grades and 19.35% showed improvement by 1 grade. Quantitative assessment showed that 58% of the patients had moderate, 29% had minimal, 9% had good and 3% showed very good improvement. Adverse effects were limited to transient pain, erythema, edema and hyperpigmentation. Conclusion: Microneedling fractional radiofrequency is efficacious for the treatment of moderate and severe acne scars.

    In December of 2002, the FDA approved azelaic acid 15% gel for the topical treatment of inflammatory papules and pustules of mild to moderate rosacea. Azelaic acid is a saturated dicarboxylic acid, which is naturally occurring and has been used in the treatment of rosacea, acne, and melasma. The 15% gel has a high efficacy and is generally well tolerated, with the local irritation (burning, stinging, itching, and scaling) being typically mild and transient. Azelaic acid 15% gel is considered effective and safe as a therapy for inflammatory papulo-pustular rosacea and is suitable for use on all skin types.

In particular, acne inflammatory lesions result from Propionibacterium acnes colonization and are of particular relevance as they can cause permanent scarring. Acne also causes significant psychological morbidity in affected patients. Products currently available for the treatment of acne include systemic and topical treatments. As these products can cause severe side effects, new, innovative therapies are needed. Farmaka Acne Cream (FAC is a novel, film-forming cream developed to treat mild and moderate acne. In vitro studies have demonstrated that FAC is as effective as 5% benzoyl peroxide in inhibiting growth of P. acnes. In 32 subjects with mild or moderate acne, FAC reduced all the major signs and symptoms of the disease. These included itching, erythema, and scaling, as well as reductions in the numbers of papules, pustules, and open and closed comedones. Acne severity improved in 38% of subjects, while none worsened. FAC was found to be effective in controlling sebum secretion, and was non-comedogenic. Most subjects (90% reported tolerability as good or very good, while clinical efficacy and cosmetic acceptability were judged as good. For assessment of contact sensitization and photosensitization, FAC was applied daily to the backs of 29 subjects in two symmetric areas for 10 days. Using a solar stimulator, one minimal erythema dose was delivered to one side of the back from days 11 to 13. The four different subareas of treated/untreated and irradiated/nonirradiated and combinations thereof were compared. No cases of contact sensitization or photosensitization were observed, and FAC is considered safe for use in intense sunlight. In vitro and in vivo studies provide

    Fractional radiofrequency microneedling is a novel radiofrequency technique that uses insulated microneedles to deliver energy to the deep dermis at the point of penetration without destruction of the epidermis. It has been used for the treatment of various dermatological conditions including wrinkles, atrophic scars and hypertrophic scars. There have been few studies evaluating the efficacy of fractional radiofrequency microneedling in the treatment of acne, and none measuring objective parameters like the number of inflammatory and non-inflammatory acne lesions or sebum excretion levels. The safety and efficacy of fractional radiofrequency microneedling in the treatment of acne vulgaris was investigated. In a prospective clinical trial, 25 patients with moderate to severe acne were treated with fractional radiofrequency microneedling. The procedure was carried out three times at 1-month intervals. Acne lesion count, subjective satisfaction score, sebum excretion level and adverse effects were assessed at baseline and at 4, 8 and 12 weeks after the first treatment as well as 4, 8 and 12 weeks after the last treatment. Number of acne lesions (inflammatory and non-inflammatory) decreased. Sebum excretion and subjective satisfaction were more favorable at every time point compared with the baseline values (P acne vulgaris. © 2014 Japanese Dermatological Association.

  8. A Honey Trap for the Treatment of Acne: Manipulating the Follicular Microenvironment to Control Propionibacterium acnes

    Directory of Open Access Journals (Sweden)

    E. Anne Eady

    2013-01-01

    Full Text Available Today, as 40 years ago, we still rely on a limited number of antibiotics and benzoyl peroxide to treat inflammatory acne. An alternative way of suppressing the growth of Propionibacterium acnes is to target the environment in which it thrives. We conjecture that P. acnes colonises a relatively “extreme” habitat especially in relation to the availability of water and possibly related factors such as ionic strength and osmolarity. We hypothesise that the limiting “nutrient” within pilosebaceous follicles is water since native sebum as secreted by the sebaceous gland contains none. An aqueous component must be available within colonised follicles, and water may be a major factor determining which follicles can sustain microbial populations. One way of preventing microbial growth is to reduce the water activity ( of this component with a biocompatible solute of very high water solubility. For the method to work effectively, the solute must be small, easily diffusible, and minimally soluble in sebaceous lipids. Xylose and sucrose, which fulfil these criteria, are nonfermentable by P. acnes and have been used to reduce water activity and hence bacterial colonisation of wounds. A new follicularly targeted topical treatment for acne based on this approach should be well tolerated and highly effective.

  9. Novel pharmacological approaches for the treatment of acne vulgaris.

    2014-10-01

    Acne vulgaris is the most common skin disease worldwide; yet, current treatment options, although effective, are associated with unwanted side effects, chronicity, relapses and recurrences. The adequate control of the four pathogenic mechanisms, involved in the appearance of acne lesions, is paramount to treatment success. The authors discuss and evaluate the pathogenic pathways related to the mechanisms of action of novel molecules, which are currently under investigation for the treatment of acne vulgaris. The manuscript is based on comprehensive searches made through PubMed, GoogleScholar and ClinicalTrial.gov, using different combination of key words, which include acne vulgaris, pathogenesis, treatment, sebogenesis and Propionibacterium acnes. In the near future, more effective treatments with fewer side effects are expected. The use of topical antiandrogens, acetylcholine inhibitors and PPAR modulators seem to be promising options for controlling sebum production. Retinoic acid metabolism-blocking agents and IL-1α inhibitors have the potential to become legitimate alternative options to retinoid therapy in the management of infundibular dyskeratosis. Indeed, the authors believe that there will likely be a decline in the use of antibiotics for controlling P. acnes colonization and targeting the inflammation cascade.

    The Gram-positive, anaerobic-aerotolerant bacterium Cutibacterium acnes is a commensal of human healthy skin, subdivided into six main phylogenetic groups or phylotypes: IA1, IA2, IB, IC, II and III. To decipher how far C. acnes specific subgroups are involved in disease physiopathology, different molecular typing methods have been developed to identify these subgroups (i.e. phylotypes, clonal complexes, SLST-types). However, as there were several molecular typing methods developed over the last decade, comparing the results from one article to another became a difficult task. Based on the scientific literature, the aim of this narrative review is to propose a standardized method to perform C. acnes molecular typing, according to the degree of resolution needed (phylotypes, clonal complexes, or SLST-types). We discuss the different typing methods existing with a critical point of view, raising the advantages/drawbacks, and identify the most frequently used. Consequently, we propose a consensus algorithm according to the needed phylogeny resolution level. We first propose to use multiplex PCR for phylotype identification, MLST9 for clonal complex determination, and SLST for phylogeny investigation including numerous isolates. There is an obvious need to create a consensus about C. acnes molecular typing methods. This standardization will facilitate the comparison of the results from one article to another, and also the interpretations of clinical data. Copyright © 2018. Published by Elsevier Ltd.

    Approximately 95% of the population suffers at some point in their lifetime from acne vulgaris. Acne is a multifactorial disease of the pilosebaceous unit. This inflammatory skin disorder is most common in adolescents but also affects neonates, prepubescent children, and adults. Topical conventional systems are associated with various side effects. Novel drug delivery systems have been used to reduce the side effect of drugs commonly used in the topical treatment of acne. Topical treatment of acne with active pharmaceutical ingredients (API) makes direct contact with the target site before entering the systemic circulation which reduces the systemic side effect of the parenteral or oral administration of drug. The objective of the present review is to discuss the conventional delivery systems available for acne, their drawbacks, and limitations. The advantages, disadvantages, and outcome of using various carrier-based delivery systems like liposomes, niosomes, solid lipid nanoparticles, and so forth, are explained. This paper emphasizes approaches to overcome the drawbacks and limitations associated with the conventional system and the advances and application that are poised to further enhance the efficacy of topical acne formulations, offering the possibility of simplified dosing regimen that may improve treatment outcomes using novel delivery system.

    Full Text Available There are a lot of works, which are devoted to the study of acne, but these data are often contradictory on the issue of interrelationship and interdependence of clinical manifestations, course and some factors in the pathogenesis of acne and candida infection. Aim of the research was to study the effect of the recommended differentiated therapy on the pathogenetic disorders in patients with acne and concomitant Candida infection. Methods and results. 120 patients with acne were examined. In 100 of them concomitant skin malasseziosis was set in the form of pityriasis rosea, kerosis, comedones, folliculitis, seborrhea, multicolored zoster, with some features, as well as candidiasis. Methods of the research – bacterioscopic, bacteriological, study of skin oiliness and moisture, skin pH, the level of Ca ++, parathyroid hormone and calcitonin. In patients with acne significant shifts in the composition of water-lipid mantle, increased oiliness and decreased moisture of skin, pH changes with a shift to the alkaline side were revealed, the most pronounced – in acne patients with Candida infection. The content of Ca ++ in the organism, as well as parathyroid hormone and calcitonin was increased and also the most indicative it was in patients with acne and concomitant Candida infection. After the comparative analysis on the basis of different levels of clinical and laboratory violations two clinical-therapeutic groups were distinguished, in accordance with that the differentiated therapy offered by us was conducted. Increased oiliness and Рh of skin, decline of moisture before the treatment, especially in patients with III and IV stages of acne, complicated by Candida infection, were normalized after treatment, unlike in patients treated traditionally. Conclusion. After treatment intensity of microbal colonization and also microbal associations of skin was diminished, the level of Ca++, parathyroid hormone and calcitonin went down.

    This review focuses on the subject of acne in women, a disease that is increasingly common and that can also affect men. Adult acne differs from the type of acne that occurs in teenagers, and it may persist beyond adolescence or have its onset at an older age (adult-onset acne or late acne). Acne can have a negative impact on the quality of life of patients at any age, leading to a negative body image and decrease in self-esteem, and in older patients it can result in discrimination in the workplace and in other social environments. Acne in women must be understood as a specific problem, and here we discuss the pathogenesis, clinical presentation, psychology and treatment of this very prevalent problem. © 2015 British Association of Dermatologists.

    Propionibacterium acnes (P. acnes) is a Gram-positive bacterium strongly associated with acne infection. While many antimicrobial agents have been used in clinic to treat acne infection by targeting P. acnes, these existing anti-acne agents usually produce considerable side effects. Herein, the development and evaluation of liposomal lauric acids (LipoLA) is reported as a new, effective and safe therapeutic agent for the treatment of acne infection. By incorporating lauric acids into the lipid bilayer of liposomes, it is observed that the resulting LipoLA readily fuse with bacterial membranes, causing effective killing of P. acnes by disrupting bacterial membrane structures. Using a mouse ear model, we demonstrated that the bactericidal property of LipoLA against P. acne is well preserved at physiological conditions. Topically applying LipoLA in a gel form onto the infectious sites leads to eradication of P. acnes bacteria in vivo. Further skin toxicity studies show that LipoLA does not induce acute toxicity to normal mouse skin, while benzoyl peroxide and salicylic acid, the two most popular over-the-counter acne medications, generate moderate to severe skin irritation within 24 h. These results suggest that LipoLA hold a high therapeutic potential for the treatment of acne infection and other P. acnes related diseases. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.

    Fractional ablative CO(2) laser therapy is based on the theory of fractional photothermolysis. It can be effective in treating acne scars in a less invasive fashion than conventional ablative CO(2) laser therapy. In this clinical study, the safety and efficacy of a novel CO(2) fractional ablative laser was investigated for the treatment of facial atrophic acne scarring in Chinese individuals. A total of 31 patients (11 females, 20 males, Fitzpatrick skin phototypes III-IV) with facial acne scarring received three sequential fractional treatments over a 6-month period. Outcome measurements included blinded evaluations of before and after photographs by two physicians at 3 and 12 months after the final treatment. Global improvement was noted as well as any untoward events. At the 12 months follow-up time period, 12.9% of the patients showed excellent improvement in their acne scars, while 38.71% noted good to fair results. The clinical response at the 12-month follow-up visit tended to be better than at the 3-month follow-up visit, but was not statistically significant. Four patients experienced post-treatment and transient PIH but three patients were noted to have prolonged erythema. There was no evidence hypopigmentation or worsening of the scarring in any of the study patients. This high-energy pulsed and cool-scanned fractional ablative CO(2) laser system is safe and effective for facial atrophic acne scarring. Improvement in scarring was noted in the majority of patients with minimal discomfort and minimal downtime. Continued improvement over time is also an important clinical finding.

    Topical dapsone gel, 5% is approved for treatment of acne vulgaris but has not been studied specifically in women with skin of color (SOC; Fitzpatrick skin types IV, V, or VI). Evaluate safety and efficacy of dapsone gel, 5% applied topically twice daily for 12 weeks in women with SOC. Females with SOC aged 18 years and older with facial acne participated in a multicenter, open-label, single-group, 12-week pilot study of twice-daily monotherapy with dapsone gel, 5%. The investigator-rated 5-point Global Acne Assessment Score (GAAS) was used to assess efficacy. The impact of acne on subjects was assessed using the validated Acne Symptom and Impact Scale (ASIS). The study enrolled and treated 68 women with SOC and facial acne. GAAS decreased significantly from baseline to week 12 (mean, -1.2 [95% CI, -1.4, -1.0]; PDapsone gel, 5% monotherapy was associated with significant improvement in subject-assessed acne signs (PDapsone gel, 5% used twice daily was well tolerated, with no treatment-related adverse events. The local dermal tolerability scores tended to remain stable or decrease from baseline to week 12. Monotherapy with dapsone gel, 5% administered twice daily was safe and effective for treatment of facial acne in women with SOC. Significant improvement in overall acne severity and both inflammatory lesions and comedones was observed. Further, study subjects reported considerable improvement in both acne signs and impact on QOL.

    Crowdsourcing is a novel process of data collection that can provide insight into the effectiveness of acne treatments in real-world settings. Little is known regarding the feasibility of crowdsourcing as a means of collecting dermatology research data, the quality of collected data, and how the data compare to the published literature. The objective of this analysis is to compare acne data collected from a medical crowdsourcing site with high-quality controlled studies from peer-reviewed medical literature. Crowdsourced data was collected from 662 online acne patients. Online patients reported data in a Likert-type format to characterize their symptom severity (740 total responses) and their treatment outcomes (958 total responses). The crowdsourced data were compared with meta-analyses and reviews on acne treatment from August 20, 2010 to August 20, 2011. We compared topical, oral systemic, alternative, phototherapy, and physical acne treatments of crowdsourced data to published literature. We focused on topical tretinoin due to the large number of online patient responses. While approximately 80% of tretinoin users observed clinical improvement after a 12-week treatment period in clinical trials, 46% of online users reported improvement in an unspecified time period. For most topical treatments, medication with high efficacy in clinical trials did not produce high effectiveness ratings based on the crowdsourced online data. While limitations exist with the current methods of crowdsourced data collection, with standardization of data collection and use of validated instruments, crowdsourcing will provide an important and valuable platform for collecting high-volume patient data in real-world settings.

    Full Text Available Background: While laser resurfacing remains the most effective treatment option for atrophic acne scars, the high incidence of post-treatment adverse effects limits its use. Fractional laser photothermolysis attempts to overcome these limitations of laser resurfacing by creating microscopic zones of injury to the dermis with skip areas in between. Aim: The aim of the present study is to assess the efficacy and safety of fractional CO 2 laser resurfacing in atrophic facial acne scars. Materials and Methods: Sixty patients with moderate to severe atrophic facial acne scars were treated with 3-4 sessions of fractional CO 2 laser resurfacing at 6-week intervals. The therapeutic response to treatment was assessed at each follow up visit and then finally 6 months after the last laser session using a quartile grading scale. Response to treatment was labelled as ′excellent′ if there was >50% improvement in scar appearance and texture of skin on the grading scale while 25-50% response and <25% improvement were labelled as ′good′ and ′poor′ response, respectively. The overall satisfaction of the patients and any adverse reactions to the treatment were also noted. Results: Most of the patients showed a combination of different morphological types of acne scars. At the time of final assessment 6 months after the last laser session, an excellent response was observed in 26 patients (43.3% while 15 (25% and 19 patients (31.7% demonstrated a good and poor response respectively. Rolling and superficial boxcar scars responded the best while pitted scars responded the least to fractional laser monotherapy. The commonest reported adverse effect was transient erythema and crusting lasting for an average of 3-4 and 4-6 days, respectively while three patients developed post-inflammatory pigmentation lasting for 8-12 weeks. Conclusions: Fractional laser resurfacing as monotherapy is effective in treating acne scars especially rolling and superficial boxcar

    Full Text Available Acne vulgaris is one of the most commonly seen conditions and the immunological link is a topic of active research. Recently, the Th17 pathway has been found to play a pivotal role in acne. The adaptive immune response toward Propionibacterium acnes leads to activation of Th17 axis. Consequently, the Th17 cytokines (IL-17, IL-1 β, IL-6, and tumor growth factor, in turn, activate the various pathogenic steps in acne. Drugs such as Vitamin D3 and isotretinoin which target the Th17 pathway may offer an additional pathway for their therapeutic response.

  5. Light/laser therapy in the treatment of acne vulgaris.

    Acne vulgaris is one of the most prevalent skin diseases known. As common as this condition is, the social and psychological consequences are limitless. Although current treatments are available and include topical or oral antibiotics, it is crucial to develop a less risky and more effective therapy such as light/laser therapy. This article focuses specifically on the benefits of the light/laser treatment on acne vulgaris. Porphyrins accumulated in the bacteria, Propionibacterium acnes, one of the etiologic factors involved in the pathogenesis, allows phototherapy to be a successful modality. They have specific absorption peaks at which lasers have optimal effects. The longer the wavelength of the light is, the deeper its penetration and thus the greater its damage to the sebaceous glands. Although blue light is best for the activation of porphyrins, red light is best for deeper penetration and an anti-inflammatory effect. Ultraviolet (UV) light, although it may have initial an anti-inflammatory effects, has been proven to be potentially carcinogenic and have adverse effects such as aging (by UV-A) and burning (by UV-B). Previous studies indicate successful long-term intervention and selective damage of the sebaceous glands by using a diode laser with indocyanine green (ICG) dye. Mid-infrared lasers have been found to decrease lesion counts while also reducing the oiliness of skin and the scarring process. Nonablative laser treatment of acne scars using the Er:YAG laser with a short-pulsed mode has been successful in reducing the appearance of scars by stimulating neocollagenesis. The light/laser therapy has started to be explored with promising results in highly selected patients that require further investigation in greater populations and well-designed protocols.

    Full Text Available Background : Despite the many advances, scarring, particularly acne or pimple scarring, does not have a satisfactory treatment. A new armamentarium in this field is this recently devised matrix-tunable radiofrequency technology, which utilizes radiofrequency emission in the treatment of acne scars. Aims : To evaluate the efficiency of the new matrix-tunable radiofrequency technology in patients with acne scars of varying sizes. Settings and Design : A prospective study of 30 randomly selected patients with acne scars was carried out. Materials and Methods : Thirty healthy patients with different types of acne scars - ice pick, box and rolling type - were randomly selected. The scars were either shallow or deep, varied in size from 2 to 20 mm and ranged in number from 10 to 50. These patients were first treated with broad-spectrum antibiotics and local exfoliating agents (topical tretinoin 0.025% and then subjected to matrix-tunable radiofrequency technology. Each scar was treated at intervals of 1 month. A maximum of four such sittings were carried out. Patients were followed-up every 15 days. Results were noted at the end of 2 months and 6 months. Improvement was assessed by using the visual analog scale (VAS at 2 months and 6 months, and results were noted in terms of percentage improvement of the whole face by calculating an average of percentage improvement on the basis of interviews of the patient and his/her accompanying relatives. The visual analog scaling was performed by means of high-resolution digital photographs taken at the baseline and at each subsequent visit. Results : The VAS improvement in scars ranged from 10 to 50% at the end of 2 months to 20 to 70% at the end of 6 months. Of the 30 patients of acne scars, the cosmetic result was excellent (>60% improvement in four, good (35-60% improvement in 18 and moderate to poor (<35% improvement in eight. A few patients reported burning sensation and a mild sunburn-like sensation for

    2015-01-01

    Full Text Available Introduction: Acne is a prevalent condition in society affecting nearly 80-90% of adolescents often resulting in secondary damage in the form of scarring. Retinoic acid (RA is said to improve acne scars and reduce postinflammatory hyperpigmentation while glycolic acid (GA is known for its keratolytic properties and its ability to reduce atrophic acne scars. There are studies exploring the combined effect of retinaldehyde and GA combination with positive results while the efficacy of retinoic acid and GA (RAGA combination remains unexplored. Aim: The aim of this study remains to retrospectively assess the efficacy of RAGA combination on acne scars in patients previously treated for active acne. Materials and Methods: A retrospective assessment of 35 patients using topical RAGA combination on acne scars was done. The subjects were 17-34 years old and previously treated for active acne. Case records and photographs of each patient were assessed and the acne scars were graded as per Goodman and Baron′s global scarring grading system (GSGS, before the start and after 12 weeks of RAGA treatment. The differences in the scar grades were noted to assess the improvement. Results: At the end of 12 weeks, significant improvement in acne scars was noticed in 91.4% of the patients. Conclusion: The RAGA combination shows efficacy in treating acne scars in the majority of patients, minimizing the need of procedural treatment for acne scars.

    Acne vulgaris represents both a challenge to the treating dermatologist and a major concern for the patient. Conventional treatments have proved inconsistent with often unacceptable side effects and high rates of recurrence. Non-thermal, non-laser, phototherapy for acne with a combination of blue and red light has recently attracted attention. The present study was designed to assess the efficacy of this combination phototherapy. Twenty-four subjects, Fitzpatrick skin types II-V, with mild to severe symmetric facial acne vulgaris were recruited for the study. Subjects were well matched at baseline in terms of both age and duration of acne. Subjects were treated over eight sessions, two per week 3 days apart, alternating between 415 nm blue light (20 minutes/session, 48 J/cm2) and 633 nm red light (20 minutes/session, 96 J/cm2) from a light-emitting diode (LED)-based therapy system. Patients received a mild microdermabrasion before each session. Acne was assessed at baseline and at weeks 2, 4, 8 and 12. Twenty-two patients completed the trial. A mean reduction in lesion count was observed at all follow-up points. At the 4-week follow-up, the mean lesion count reduction was significant at 46% (p=0.001). At the 12-week follow-up, the mean lesion count reduction was also significant at 81% (p=0.001). Patient and dermatologist assessments were similar. Severe acne showed a marginally better response than mild acne. Side effects were minimal and transitory. Comedones did not respond as well as inflammatory lesions. Combination blue and red LED therapy appears to have excellent potential in the treatment of mild to severe acne. Treatment appears to be both pain- and side effect-free.

    Full Text Available We previously described a Multilocus Sequence Typing (MLST scheme based on eight genes that facilitates population genetic and evolutionary analysis of P. acnes. While MLST is a portable method for unambiguous typing of bacteria, it is expensive and labour intensive. Against this background, we now describe a refined version of this scheme based on two housekeeping (aroE; guaA and two putative virulence (tly; camp2 genes (MLST4 that correctly predicted the phylogroup (IA1, IA2, IB, IC, II, III, clonal complex (CC and sequence type (ST (novel or described status for 91% isolates (n = 372 via cross-referencing of the four gene allelic profiles to the full eight gene versions available in the MLST database (http://pubmlst.org/pacnes/. Even in the small number of cases where specific STs were not completely resolved, the MLST4 method still correctly determined phylogroup and CC membership. Examination of nucleotide changes within all the MLST loci provides evidence that point mutations generate new alleles approximately 1.5 times as frequently as recombination; although the latter still plays an important role in the bacterium's evolution. The secreted/cell-associated 'virulence' factors tly and camp2 show no clear evidence of episodic or pervasive positive selection and have diversified at a rate similar to housekeeping loci. The co-evolution of these genes with the core genome might also indicate a role in commensal/normal existence constraining their diversity and preventing their loss from the P. acnes population. The possibility that members of the expanded CAMP factor protein family, including camp2, may have been lost from other propionibacteria, but not P. acnes, would further argue for a possible role in niche/host adaption leading to their retention within the genome. These evolutionary insights may prove important for discussions surrounding camp2 as an immunotherapy target for acne, and the effect such treatments may have on commensal

    Acne vulgaris (acne) is prevalent in individuals with skin of color, often with more frequent sequelae than in patients with lighter skin color. It is important to determine if there are also differences in response to medications. This study evaluated the efficacy and tolerability of once-daily dapsone gel, 7.5% in patients with acne, stratified by Fitzpatrick skin phototype. Data were pooled from 2 identically designed, phase 3, randomized, double-blind, vehicle-controlled studies in patients aged 12 years and older with moderate acne. Patients applied dapsone gel, 7.5% or vehicle once daily for 12 weeks. Efficacy was evaluated using the Global Acne Assessment Score (GAAS), lesion counts, and Acne Symptom and Impact Scale (ASIS); adverse events (AEs) and tolerability were also assessed. This analysis included 2216 patients with skin phototypes I-III and 2111 with types IV-VI. Dapsone gel, 7.5% significantly improved acne severity versus vehicle in both skin phototype subgroups, as determined by the percentage of patients with at least a 1-grade improvement in GAAS and mean change from baseline in GAAS (both, P less than .0001) at week 12 versus baseline. Dapsone gel, 7.5% significantly reduced inflammatory, comedonal, and total lesions in skin phototypes I-III (P less than .001) and IV-VI (P less than equal to .01) versus vehicle. Improvements in inflammatory lesions occurred first, with generally similar patterns of improvement seen over time in GAAS, comedonal lesions, and ASIS domains. The incidence of AEs was similar in both skin phototype subgroups and between study medications. Local scaling, erythema, stinging/burning, and dryness were rated "none" by most patients in both treatment groups and skin phototype subgroups. Once-daily dapsone gel, 7.5% was effective, safe, and well tolerated in patients with all skin phototypes who were treated for moderate acne. J Drugs Dermatol. 2018;17(2):160-167.

    Acne vulgaris is a common dermatologic disease in African patients, as well as in Caucasians. Our report evaluates the safety and efficacy of adapalene gel 0.1% in African patients with acne vulgaris. We used a 12-week, 2-center, open-label, noncomparative study of adapalene gel 0.1% in 65 African patients with acne vulgaris to assess the drug's effect on hyperpigmented lesions in people with dark skin. The study demonstrated that the progressive and significant improvements in lesion counts and global acne grades produced by adapalene in African patients were paralleled by significant improvements in the degree of hyperpigmentation of acne lesions. During treatment with adapalene, less than 5% of patients reported moderate or severe skin irritation at any time during the study, and the incidence of skin oiliness decreased markedly. We conclude that adapalene gel 0.1% was well tolerated and highly effective in African patients with acne vulgaris and was found to reduce hyperpigmentation.

    2017-06-01

    INTRODUCTION: Truncal acne is often associated with facial acne, but there are fewer options for an effective topical treatment on the trunk. Given the advent of foam formulations with enhanced percutaneous absorption and convenient application due to easy spreadability on skin, the previously held idea that effective treatment of truncal acne requires oral treatment is challenged. Azelaic acid cream has been previously approved for acne vulgaris, thus azelaic acid foam may be a viable treatment option for truncal acne. STUDY DESIGN: A single-center, open label pilot study was conducted to investigate the efficacy and safety of azelaic acid 15% foam as a treatment modality for moderate truncal acne. Use for facial acne was also allowed and monitored during the study. RESULTS: Twice-daily application of azelaic acid 15% foam to affected areas resulted in a 1-grade reduction in truncal investigator global assessment (IGA) scores in nearly all patients (16/18). Eight out of 18 patients (44%) were rated as Clear or Almost Clear in the trunk by the end of the study. There were also improvements in facial IGA scores; 9 of 18 patients (50%) exhibited a 1-grade improvement in IGA scores and 11 of 18 were Clear or Almost Clear by the end of the study. A significant reduction in lesion counts was found throughout the study and the medication was well tolerated. CONCUSION: Azelaic acid 15% foam was effective in treating moderate truncal acne and facial acne in this pilot study. Given the efficacy and convenience of the foam vehicle, azelaic acid may be considered as a viable option for treatment of acne vulgaris, including on the trunk. Further studies are suggested in a larger population of patients, including adult females with acne. J Drugs Dermatol. 2017;16(6):534-538..

    Although there are few differences in the incidence and pathophysiology of acne across various races and ethnicities, there is some evidence that black patients may have larger sebaceous glands and increased sebum production. Of greater clinical relevance, patients with darker skin types are at increased risk for the development of post-inflammatory hyperpigmentation (PIH), which some find as or more troubling than acne itself. This common and bothersome sequelum of acne can be difficult to manage in this population. Topical azelaic acid gel is recognized to have anti-tyrosinase activity, suggesting it may be a suitable treatment option for mild-to-moderate acne with associated moderate-to-severe PIH. This pilot study demonstrates the efficacy of topical AzA gel 15% when applied twice daily for the reduction of both acne and PIH. J

    The effective and safe treatment of acne vulgaris often is affected by individual patient characteristics, including skin color and cultural background. Skin of color is especially prone to hyperpigmentation, both from lesions and from irritating therapy. Clinicians also should be aware of cultural attitudes and folk remedies that may adversely affect dermatologic conditions such as acne. Copyright © 2011 Elsevier Inc. All rights reserved.

    A minimally invasive fractional radiofrequency microneedle (FRM) device has been used in skin rejuvenation and acne scars, and a recent pilot study demonstrated the positive therapeutic effect on acne. We evaluated the efficacy of FRM device for acne vulgaris in Asians and conducted objective measurement to assess its effect on sebum production. Twenty Korean patients with acne vulgaris received a single full-face FRM treatment. Outcome assessments included standardized photography, physician's global assessment, patient's satisfaction scores, acne lesion count, and objective measurements of casual sebum level (CSL) and sebum excretion rate (SER). They were evaluated at baseline and 2, 4, 8 weeks after the treatment. After a single FRM treatment, the CSL and the SER showed 30-60% and 70-80% reduction, respectively, at week 2 (P acne severity and acne lesion count also revealed clinical improvement with maximum efficacy at week 2, but returned to the baseline in most patients by week 8. Patients' satisfaction scores (0-4) were above 2 on average, and adverse effects were minimal. This prospective study demonstrated the sebosuppressive effect from a single FRM treatment, but its therapeutic efficacy in acne requires further evaluation. © 2013 Wiley Periodicals, Inc.

    Full Text Available Brian J Simmons, Robert D Griffith, Leyre A Falto-Aizpurua, Keyvan Nouri Department of Dermatology and Cutaneous Surgery, University of Miami Miller School of Medicine, University of Miami, Miami, FL, USA Abstract: Acne is a common affliction among many teens and some adults that usually resolves over time. However, the severe sequela of acne scarring can lead to long-term psychological and psychiatric problems. There exists a multitude of modalities to treat acne scars such as more invasive surgical techniques, subcision, chemical peels, ablative lasers, fractional lasers, etc. A more recent technique for the treatment of acne scars is nonablative radiofrequency (RF that works by passing a current through the dermis at a preset depth to produce small thermal wounds in the dermis which, in turn, stimulates dermal remodeling to produce new collagen and soften scar defects. This review article demonstrates that out of all RF modalities, microneedle bipolar RF and fractional bipolar RF treatments offers the best results for acne scarring. An improvement of 25%–75% can be expected after three to four treatment sessions using one to two passes per session. Treatment results are optimal approximately 3 months after final treatment. Common side effects can include transient pain, erythema, and scabbing. Further studies are needed to determine what RF treatment modalities work best for specific scar subtypes, so that further optimization of RF treatments for acne scars can be determined.

    Acne vulgaris is a chronic inflammatory disease - rather than a natural part of the life cycle as colloquially viewed - of the pilosebaceous unit (comprising the hair follicle, hair shaft and sebaceous gland) and is among the most common dermatological conditions worldwide. Some of the key mechanisms involved in the development of acne include disturbed sebaceous gland activity associated with hyperseborrhoea (that is, increased sebum production) and alterations in sebum fatty acid composition, dysregulation of the hormone microenvironment, interaction with neuropeptides, follicular hyperkeratinization, induction of inflammation and dysfunction of the innate and adaptive immunity. Grading of acne involves lesion counting and photographic methods. However, there is a lack of consensus on the exact grading criteria, which hampers the conduction and comparison of randomized controlled clinical trials evaluating treatments. Prevention of acne relies on the successful management of modifiable risk factors, such as underlying systemic diseases and lifestyle factors. Several treatments are available, but guidelines suffer from a lack of data to make evidence-based recommendations. In addition, the complex combination treatment regimens required to target different aspects of acne pathophysiology lead to poor adherence, which undermines treatment success. Acne commonly causes scarring and reduces the quality of life of patients. New treatment options with a shift towards targeting the early processes involved in acne development instead of suppressing the effects of end products will enhance our ability to improve the outcomes for patients with acne.

  19. COMPARATIVE STUDY OF FRACTIONAL CO2 LASER AND DERMAROLLER IN THE TREATMENT OF ATROPHIC FACIAL ACNE SCARS

    Directory of Open Access Journals (Sweden)

    Full Text Available BACKGROUND Atrophic scars results from any inflammatory skin disease causing sufficient damage to epidermis and dermal collagen. The most common causes of atrophic scars are severe nodular or nodulocystic acne. Main morphological types of atrophic post-acne scars are icepick scars, superficial or deep boxcar scars and rolling scars and various modalities of treatments are available. MATERIALS AND METHODS Total of 50 cases were enrolled in study with grade 2 and 3 acne scars according to Goodman and Baron qualitative scar grading scale treated randomly selected modality of treatment by envelope method followed by alternate modality of treatment with 25 cases of each modality. Patients were selected with the predetermined inclusion and exclusion criterias. Patient followed up monthly after initiation of therapy for a period of six months. RESULTS All patients in Dermaroller group improved of which 88% improved by at least one grade and 12% patients showed improvement of the scars by 2 grades in Goodman and Baron qualitative scar grading scale. All the patients in fractional CO2 laser group showed improvement, of which 80% improved by 1 grade and rest 20% by another 2 grades in Goodman and Baron qualitative scar grading scale. CONCLUSION It is important to realise that a typical patient has scars of different morphological types and grades and it is difficult to treat all these scar types satisfactorily with a single treatment option. However, of all the treatment options available to treat post-acne scars, fractional photothermolysis is probably the only monotherapy that offers the highest degree of scar amelioration and patient satisfaction. On the other hand, Dermaroller is a simple, inexpensive office method of treatment for management of facial acne scars with relatively less downtime, but less satisfactory results as compared to fractional CO2 laser.

    Photodynamic therapy using topical 5-aminolevulinic acid (ALA) has been successful in treating acne vulgaris, but sun avoidance for at least 48 hours after treatment is necessary due to the risk of post-treatment photosensitivity. Recently, a lower concentration of liposome-encapsulated 5-ALA was introduced to minimize this risk. To evaluate the efficacy and safety of liposome-encapsulated 0.5% 5-ALA in the photodynamic therapy of inflammatory acne and its effects on sebum secretion in Asian skin. Thirteen Korean subjects with inflammatory acne were administered 0.5% ALA spray before photoradiation treatment. Photoradiation was performed at 3.5-6.0 J/cm(2) three times during each of two visits, performed 2 weeks apart. Improvement of acne was evaluated subjectively and objectively based on the Korean Acne Grading System. Sebum secretion was measured quantitatively at each visit. The mean reduction in acne grade at the end of the treatment was 43.2%. Of the patients, 69.2% reported improvements in subjective skin oiliness, but fewer showed objective reductions in sebum secretion as determined by the Sebumeter® SM10. No serious adverse events were observed. Photodynamic therapy using liposome-encapsulated 0.5% 5-ALA improved inflammatory acne with minimal side effects in Asians.

    Acne vulgaris, a multi-factorial disease, is one of the most common skin diseases, affecting an estimated 80% of Americans at some point during their lives. The gram-positive and anaerobic Propionibacterium acnes (P. acnes) bacterium has been implicated in acne inflammation and pathogenesis. Therapies for acne vulgaris using antibiotics generally lack bacterial specificity, promote the generation of antibiotic-resistant bacterial strains, and cause adverse effects. Immunotherapy against P. acnes or its antigens (sialidase and CAMP factor) has been demonstrated to be effective in mice, attenuating P. acnes-induced inflammation; thus, this method may be applied to develop a potential vaccine targeting P. acnes for acne vulgaris treatment. This review summarizes reports describing the role of P. acnes in the pathogenesis of acne and various immunotherapy-based approaches targeting P. acnes, suggesting the potential effectiveness of immunotherapy for acne vulgaris as well as P. acnes-associated diseases.

    To collect information about how people with acne make day-to-day decisions concerning the effectiveness of their treatment. Between May and August 2013, an optional question was embedded in the James Lind Alliance Acne Priority Setting Partnership's online survey to collect treatment uncertainties. The question asked people with acne to "Tell us in your own words how you decide if your treatment has been effective." A total of 742 respondents specified at least one outcome or means of assessing change (outcome measure). Fewer spots were the most commonly cited outcome, identified by 272 respondents (36.7%). Other frequently mentioned outcomes were in descending order: less redness (19.4%), reduction in spot size (12.1%), and less pain/discomfort (11.4%). Signs were much more commonly used than symptoms and surrogate outcomes such as changes in aspects of life quality were infrequently mentioned. Visual inspection of the skin was the most widely adopted outcome measure (16.3%). Although the most frequently used methods map well onto the outcome measures adopted in the majority of acne trials, namely physician-assessed changes in lesion counts and global acne severity, people with acne often take into account several factors that cannot be assessed by a third party at a single point in time. The minimal use of changes in psychosocial wellbeing and mood may reflect that these are regarded as secondary consequences of improvements in appearance. The robustness of these findings now requires independent evaluation. If confirmed, they could form the basis of a new patient-reported outcome measure. © 2017 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

    The occurrence and incidence of acne scarring is different. Lasting for years, acne can cause both physical and psychological scarring. Scarring frequently results from severe inflammatory nodulocystic acne but may also result from more superficial inflamed lesions or from self-manipulation. There are two general types of acne scars: hypertrophic (keloid) scars, and atrophic (icepick, rolling and boxcar) scars. The management of acne scarring includes various types of resurfacing (chemical peels, lasers, lights, cryotherapy), use of dermal fillers, and surgical methods such as dermabrasion, subcision or punch excision. Individual scar characteristics, including color, texture and morphology, determine the treatment choice. Combining treatment methods may provide additional improvement compared with one method alone. It should be noted that none of the currently available treatments can achieve complete resolution of the scar. The best method of preventing or limiting scarring is to treat acne early enough to minimize the extent and duration of inflammation.

    This study investigated the efficacy and safety of a newly designed LED device used in photodiagnosis and photodynamic therapy of moderate to severe acne vulgaris in Chinese patients. Forty-six patients with moderate to severe facial acne showing high degrees of fluorescence by ultraviolet light examination were illuminated during ALA-PDT with two wavelengths of light (543-548 nm, and 630±6 nm, respectively) after 2 h of incubation with ALA. Each patient received treatment once every 30 days for two or three sessions. Two independent investigators assigned an acne severity score at baseline, one week after each treatment, as well as 4, 8, and 12 weeks after the completion of treatment. Adverse effects were recorded during and after each treatment. All patients rated their satisfaction with the results of treatment at a 12-week follow up visit. The ALA-PDL treatment regimen showed an overall effectiveness rate of 89.13% (41/46 patients). Some degree of clinical efficacy was seen in 71.42%, 86.67%, and 95.83% of patients with grades IV, V, and VI acne, respectively, and the rate of clinical effectiveness increased with increasing acne severity. When compared with baseline scores, significant reductions in acne scores were obtained at 8, and 12 weeks after completion of treatment. Maximum efficacy was shown at the 12 week follow up. No severe adverse events were observed. ALA-PDT administered with the newly designed LED device was an effective treatment for moderate to severe acne vulgaris, and side effects were mild and reversible. Copyright © 2015 Elsevier B.V.

    Full Text Available Background: Acne vulgaris is a chronic inflammatory disease of the pilosebaceous follicles and one of the most common skin diseases. The peeling method has been recently found to be effective for acne treatment. This study aimed to compare the efficacy of pyruvic acid 50% and salicylic acid 30% peeling in the treatment of mild to moderate acne. Materials and Methods: In a prospective single-blinded clinical trial, 86 patients with acne were randomly assigned into two groups. In both groups, the routine treatment of acne (topical solution of erythromycin 4%, triclorocarban soap, and sunscreen were used twice a day for 8 weeks. In addition, salicylic acid 30% for the control group and pyruvic acid 50% for the case group were used. In both groups, acne severity index (ASI was calculated before and at week 2, 4, 6, and 8 of the treatment. Patient satisfaction was assessed at the end of the treatment. Side effects were recorded using a checklist. Results: In both groups, the reduction in the number of comedones, papules, and ASI were statistically significant (P < 0.001 in the course of treatment. However, it was not significant regarding the number of pustules (P = 0.09. None of the number of comedone, papules, pustules, and ASI was statistically different between study groups. Both treatment groups had similar side effects except for scaling in the fifth session, which was significantly lower in salicylic acid - treated patients (P = 0.015. Conclusion: Both pyruvic acid 50% and salicylic acid 30% are effective in the improvement of mild to moderate acne with no significant difference in efficacy and side effects.

    The incidence of preadolescent acne among women is increasing. Acne deteriorates the quality of life; conventional treatment options are limited and have not been effective against acne, particularly acne associated with menstruation. Despite evidence that acne associated with menstruation abnormalities naturally improves when menstruation recovers to normal, there have only been few studies on the effects of dysmenorrhea treatment on acne. Therefore- we designed this study to assess the effects of gyejibokryung-hwan (GBH) and dangguijagyag-san (DJS), which are widely used in dysmenorrhea treatment, on acne associated with menstruation cycle. This is a protocol for a randomized, double-blind, parallel-group, placebo-controlled and multicenter trial. One hundred and sixteen participants with dysmenorrhea accompanied by acne vulgaris will be recruited at three centers and randomized into two groups, the herbal treatment group and placebo group. The participants will receive GBH or DJS based on pattern identification or placebo granules thrice daily for 8 weeks, with an 8-week follow up. The primary outcome will be the mean percentage change in the count of inflammatory acne lesions. The secondary outcomes would be based on dysmenorrhea numeric rating scale, verbal multidimensional scoring system for dysmenorrhea, acne numeric rating scale, investigator's static global assessment scale of facial acne vulgaris, and safety testing. Adverse events will also be reported. The effects of GBH or DJS used in dysmenorrhea treatment on acne associated with the menstrual cycle will be evaluated. The findings of this trial will provide evidence regarding the effect of herbal medicine in improving acne vulgaris associated with menstruation in women.

    Full Text Available Although entrapment of nanoparticles of appropriate sizes at hair follicles has been clarified, there is no report on specific clinical application of this finding. Since sebaceous gland is associated with hair follicle, we hypothesize that effective acne vulgaris treatment/prevention can be achieved by depositing anti-acne agent in nanoparticle form at the hair follicles. Challenge of this strategy, however, lies at the finding of effective anti-acne particles with minimal skin irritation. Here using cellulose-based nanoparticles as nano-reservoir and α-mangostin (an active component isolated from the edible Garcinia mangostana Linn. fruit as anti-acne agent, we prepare nanoparticles highly loaded with α-mangostin. Ability of the obtained particles to sustained release α-mangostin into synthetic sebum is demonstrated. The obtained mangostin particles are verified for their insignificant skin irritation through the two-week, twice-daily open application test in 20 healthy human volunteers. Excellent entrapment and sustainment of the mangostin nanoparticles at the hair follicles are elucidated in six human volunteers by detecting the presence of α-mangostin at the roots of hairs pulled from the treated skin area. The 4-week-randomized, double-blind, placebo-controlled, split-face study in 10 acne patients indicates significant improvement in acne vulgaris condition on the side twice daily applied with mangostin nanoparticles.

    Full Text Available Acne surgery is the use of various surgical procedures for the treatment of postacne scarring and also, as adjuvant treatment for active acne. Surgery is indicated both in active acne and post-acne scars. Physicians′ qualifications: Any Dermatologist can perform most acne surgery techniques as these are usually taught during postgraduation. However, certain techniques such as dermabrasion, laser resurfacing, scar revisions need specific "hands-on" training in appropriate training centers. Facility: Most acne surgery procedures can be performed in a physician′s minor procedure room. However, full-face dermabrasion and laser resurfacing need an operation theatre in a hospital setting. Active acne: Surgical treatment is only an adjunct to medical therapy, which remains the mainstay of treatment. Comedone extraction is a process of applying simple mechanical pressure with a comedone extractor, to extract the contents of the blocked pilosebaceous follicle. Superficial chemical peel is a process of applying a chemical agent to the skin, so as to cause controlled destruction of the epidermis leading to exfoliation. Glycolic acid, salicylic acid and trichloroacetic acid are commonly used peeling agents for the treatment of active acne and superficial acne scars. Cryotherapy: Cryoslush and cryopeel are used for the treatment of nodulocystic acne. Intralesional corticosteroids are indicated for the treatment of nodules, cysts and keloidal acne scars. Nonablative lasers and light therapy using Blue light, non ablative radiofrequency, Nd:YAG laser, IPL (Intense Pulsed Light, PDT (Photodynamic Therapy, pulse dye laser and light and heat energy machines have been used in recent years for the treatment of active inflammatory acne and superficial acne scars. Proper counseling is very important in the treatment of acne scars. Treatment depends on the type of acne scars; a patient may need more than one type of treatment.

    The aim of this study was to evaluate changes in nasal and oropharyngeal flora in patients with acne during treatments with tetracycline and isotretinoin. Swab specimens were taken from the right and left nasal cavities and oropharynx of 55 patients with acne and 20 healthy volunteers who were admitted to the dermatology department (Etlik Educational and Research Hospital, Ankara, Turkey) before the administration of treatment and in the third month of treatment. Study participants were divided into four groups as follows: patients with acne on topical treatment only, systemic isotretinoin, and systemic tetracycline, and the control group. Of 55 patients with acne, 18 were male and 37 were female. The mean age of the patients and the control group was 22.21 ± 4.22 and 21.95 ± 7.64, respectively. Staphylococcus aureus was isolated from the nasal flora of five patients, normal flora was suppressed in the oropharyngeal cultures of seven patients, and normal flora grew in the cultures of the other 20 patients who were on tetracycline treatment. On the other hand, normal flora grew in the nasal and oropharyngeal cultures of all the patients who were on isotretinoin treatment. Treatment options and follow-up procedures for acne vulgaris may lead to the development of bacterial resistance and damage to flora. In particular, systemic tetracycline treatment leads to changes in flora of the nose and throat in patients with acne with an increased carriage of S. aureus. Therefore, careful attention should be paid to the duration of tetracycline treatment in order to not increase the risk of disturbance of microbial flora. © 2014 The International Society of Dermatology.

ASI was reduced by 65.2% and 21.3% by azelaic acid gel and the placebo respectively (P = 0.001), i.e, azelaic acid gel was 3.06 times more effective than the placebo in reducing ASI. Azelaic acid gel can be used as an effective treatment in mild to moderate acne vulgaris.

    Background Achieving a satisfying quality of life for a patient by applying individually matched therapy is, simultaneously, a great challenge and a priority for contemporary medicine. Patients with visible dermatological ailments are particularly susceptible to reduction in the general quality of life. Among the dermatological diseases, acne causes considerable reduction in the quality of life and changes in self-perception that lead to the worsening of a patient’s mental condition, including depression and suicidal thoughts. As a result, difficulties in contact with loved ones, as well as social and professional problems are observed, which show that acne is not a somatic problem alone. To a large extent, it becomes a part of psychodermatology, becoming an important topic of public health in social medicine practice. Pharmacological treatment of acne is a challenge for a dermatologist and often requires the necessity of cooperating with a cosmetologist. Cosmetological treatments are aimed at improving the condition of the skin and reduction or subsiding of acne skin changes. Aim The aim of this study was to assess the influence of selected cosmetological treatments on the general quality of life of patients with acne. Materials and methods The study group consisted of 101 women aged 19–29 years (x¯=22.5 years, SD =2.3 years). All subjects were diagnosed with acne vulgaris of the face. In the study group, the acne changes occurred over the course of 3–15 years (x¯=8.1 years, SD =2.7 years). Selected cosmetological treatments (intensive pulsing light, alpha-hydroxy acids, cavitation peeling, needle-free mesotherapy, diamond microdermabrasion and sonophoresis) were performed in series in the number depending on the particular patient’s chosen treatment, after excluding contraindications. General quality of life of the patients was estimated using the Skindex-29 and Dermatology Life Quality Index (DLQI) questionnaires, before and after the cosmetological

    Clinical question: What are the most effective treatment(s) for mild, moderate, severe, and hormonally driven acne? Results: Mild acne responds favorably to topical treatments such as benzoyl peroxide, salicylic acid, and a low-dose retinoid. Moderate acne responds well to combination therapy comprising-topical benzoyl peroxide, antibiotics, and/or retinoids, as well as oral antibiotics in refractory cases and oral contraceptive pills for female acne patients. Severe nodulocystic acne vulgaris responds best to oral isotretinoin therapy. In female patients with moderate to severe acne, facial hair, loss of scalp hair and irregular periods, polycystic ovarian syndrome should be considered and appropriate treatment with hormonal modulation given. Adjunctive procedures can also be considered for all acne patients. Implementation: Pitfalls to avoid when treating acne: treatment of acne in women of child-bearing age; familiarization of all acne treatments in order to individualize management for patients; indications for specialist referral.

    Acne vulgaris is the most common skin disease worldwide, with many available treatment modalities, including oral and topical medications and laser therapy. Recently, a novel device (Isolaz, Pleasanton, CA, USA) that combines vacuum pressure and a broadband light source (400 nm to 1,200 nm) was developed for the treatment of acne. To determine the clinical efficacy and safety of photopneumatic therapy for the treatment of acne vulgaris of the face. Twenty adults with mild to moderate facial acne vulgaris received 4 successive treatments on one side of the face with a combined photopneumatic device (intense pulsed light: fluence=5.8 J/cm(2); negative pressure=iMP mode) at 2 week intervals. Acne lesions on the opposite side of the face were not treated. Lesion counts were performed at baseline, prior to each treatment session, and at 3 months after the final treatment session. Significant lesion improvements and reduced numbers of acne lesions were observed on the treated side of the faces. Most patients experienced global clinical improvement. No severe side effects occurred during the study, with only a few patients experiencing transient erythema, purpura and/or exacerbation of pre-existing acne. Photopneumatic therapy is a safe and effective treatment for mild to moderate acne vulgaris.

The antimicrobial effectiveness of zinc ascorbate in the treatment of acne vulgaris, either alone or in combination with antibiotics such as clindamycin that are commonly used in Japan for the treatment of acne vulgaris, was therefore examined. Materials and methods: The antimicrobial susceptibility of 41 strains of clindamycin-sensitive and/or clindamycin-resistant P. acnes isolated from acne vulgaris patients was tested, in comparison with a type strain of P. acnes. Results: Zinc ascorbate showed antimicrobial activity against a type strain of P. acnes and its concentration (0.064% was sufficiently lower than the normal dose (5% of other ascorbic acid derivatives. Combinations of zinc ascorbate with clindamycin, erythromycin, and chloramphenicol showed an additive effect, and zinc ascorbate alone effectively inhibited the growth of all P. acnes including clindamycin-resistant strains. Conclusion: The results provide novel evidence that the combination of zinc ascorbate and clindamycin is effective for acne vulgaris treatment. Keywords: antimicrobial susceptibility, ascorbic acid derivatives, combination therapy, checkerboard test

    A significant number of clinical practice guidelines (CPGs) about the treatment of acne vulgaris in adolescents and adults have been published worldwide. However, little is known about the quality of CPGs in this field. The aim of this study was to appraise the methodological quality of published acne vulgaris CPGs. We performed a systematic review of published CPGs on acne vulgaris therapy from July 2002 to July 2012. Three reviewers independently assessed each CPG using the AGREE II instrument. A standardized score was calculated for each of the six domains. Our search strategy identified 103 citations but just six met our inclusion criteria. Agreement among reviewers was very good: 0.981. The domains that scored better were: "scope and purpose" and "clarity and presentation". Those that scored worse were "stakeholder involvement", "rigor of development", and "applicability". The European and the Malaysian CPGs were the only recommended with no further modifications. In addition, the Mexican, Colombian and the United States guidelines were recommended with provisos, with lower scores regarding stakeholder involvement, rigor of development and applicability. Only two guidelines clearly reported outcome measures for evaluating efficacy or included quality of life outcomes. CPGs varied regarding the consideration of light/laser therapy or consideration of complementary/alternative medicines. None of them included cost considerations of drugs such as systemic isotretinoin. In conclusion, published acne vulgaris CPGs for acne therapy vary in quality with a clear need to improve their methodological rigor. This could be achieved with the adherence to current CPGs development standards.

Isotretinoin, a vitamin A derivative, is currently the standard of care for treatment. However, it has a well-established teratogenic activity, a reason for the development of novel and low-risk treatment options for acne. Objective: To investigate the effectiveness of Zolav®, a novel antibiotic as a treatment for acne vulgaris. Materials and methods: Minimum inhibitory concentration of Zolav® against Propionibacterium acnes was determined by following a standard protocol using Mueller-Hinton broth and serial dilutions in a 96-well plate. Cytotoxicity effects on human umbilical vein endothelial cells and lung cells in the presence of Zolav® were investigated by determining the growth inhibition (GI50 concentration, total growth inhibition concentration, and the lethal concentration of 50% (LC50. The tryptophan auxotrophic mutant of Escherichia coli strain, WP2 uvrA (ATCC 49979, was used for the AMES assay with the addition of Zolav® tested for its ability to reverse the mutation and induce bacterial growth. The in vivo effectiveness of Zolav® was tested in a P. acnes mouse intradermal model where the skin at the infection site was removed, homogenized, and subjected to colony-forming unit (CFU counts. Results: Susceptibility testing of Zolav® against P. acnes showed a minimum inhibitory concentration of 2 µg/mL against three strains with no cytotoxicity and no mutagenicity observed at the highest concentrations tested, 30 µM and 1,500 µg/plate, respectively. The use of Zolav® at a concentration of 50 µg/mL (q8h elicited a two-log difference in CFU/g between the treatment group and the control

    Objectives: To evaluate the effectiveness of topical 5-aminolevulinic acid (ALA)- medicated photodynamic therapy (ALA PDT) for the treatment of moderate to severe acne vulgaris. Methods: Sixteen Chinese patients with moderate to severe facial acne were treated with 1-3 courses of ALA PDT. ALA cream (3%) was freshly prepared and applied to acne lesions for 3-4 h. The lesions were irradiated by a 635 nm diode laser at dose levels of 60 - 80 J/cm2 at 100 mW/cm2. Clinical assessments were conducted before and after treatment up to 3 months. Results: All patents showed response to ALA PDT. Complete clearance was seen in 10 patients (62.5%) and partial clearance in 6 patients (37.5%). One case showed recurrence after complete clearance at 2 months and another two showed recurrence after complete clearance at 3 months. However, the number of new lesions were significantly reduced. Adverse effects were minimal. Conclusions: The results of this preliminary clinical study is encouraging. ALA PDT is a simple, safe and useful therapeutic option for the treatment of moderate to severe acne. Further studies to evaluate the treatment with a larger number of patients and for a longer period of follow-up are needed.

Omeprazole is a proton pump inhibitor with in vitro antibacterial effects against staphylococcus aureus and anti-androgen that can be potential treatment of acne vulgaris. This study was designed to evaluate the efficacy of oral omeprazole and erythromycin 4% compared to doxycycline combination therapy in the treatment of acne vulgaris. Methods: In this clinical trial study, patients with moderate acne were referred to Skin Diseases and Leishmaniasis Research Center, Isfahan University of Medical Science, Iran, during August 2014 until November 2015 and were randomized into two groups receiving topical erythromycin 4% plus omeprazole (34 patients or doxycycline (35 patients for 3 months. Moderate acne, lack of sensitivity to proton pump inhibitors, lack of warfarin, phenytoin, diazepam consumption, lack of active liver or kidney disease, being older than 12 years, were considered as inclusion criteria. Pregnant or lactating patients, patients with drug allergy history, patients taking oral contraceptives, acne topical medications (including retinoids or systemic treatment within 30 days of study, patients with oligomenorrhea, hirsutism, acne conglobata, acne fulminant or body acne alone were excluded from the study. All patients were tested for Helicobacter pylori test at the beginning of the study. Results: Both inflammatory and non-inflammatory lesions decreased in both groups with negative correlation with age (P< 0.05. There was no significant correlation between positive Helicobacter pylori test and inflammatory or non-inflammatory lesion reduction (P= 0.794, P= 0.514. Also, patient satisfaction and rate of total drug side effects was not different between two treatment groups. Rate of skin reactions was 20.58% in omeprazole treated group and 11.42% in doxycycline group. For side effects, other than skin it was 2.94% versus 14.28% respectively

    Acne, one of the most common skin problems in dermatological practice, is a condition that affects not only adolescents but also adults. While approximately 80% of cases occurring in adulthood are persistent from teenage years, around 20% are described as 'late-onset' disease, appearing for the first time in adulthood. The disease can be triggered by hormonal changes (including a change from one contraceptive to another), or it can be induced by certain nonhormonal medications, emotional stress, and various underlying diseases such as polycystic ovary syndrome. In many cases acne becomes a chronic skin condition with undulating activity, including improvement and relapse phases, and is often experienced as a major psychological burden. It is, therefore, even more important to provide an effective as well as a safe and tolerable treatment. The spectrum of topical acne treatments has expanded substantially in recent years and various topical medications are available, ranging from azelaic acid, antibiotics, retinoids and benzoyl peroxide to several fixed combinations of these active compounds. The following case collection illustrates how 15% azelaic acid gel, as a well-established monotherapy, can be successfully employed to treat mild-to-moderate forms of adult female acne. © 2013 S.

    Full Text Available Acne conglobata is a rare and severe form of acne vulgaris, characterized by the presence of comedones, papules, pustules, nodules and sometimes hematic or meliceric crusts. Acne excoriée is a form of self-inflicted skin condition in which the patient picks on imaginary or real acne lesions. We report the case of a 16 year old Caucasian female patient from the urban area who addressed our dermatology department for erythematous, edematous plaques covered by pustules and crusts, located on the face. The anamnesis revealed that during the last weeks she had had a depressive mood after ending a relationship with her boyfriend and started scratching and picking on the lesions. The patient's depressive mood prior to the worsening of the disease was probably aggravated by the condition. This might have determined the picking of the skin which could have impeded the response to standard treatment. The selfexcoriative behavior could also be regarded as an appeal for help.

  13. A novel high-resolution single locus sequence typing scheme for mixed populations of Propionibacterium acnes in vivo.

    Christian F P Scholz

    Full Text Available The Gram-positive anaerobic bacterium Propionibacterium acnes is a prevalent member of the normal skin microbiota of human adults. In addition to its suspected role in acne vulgaris it is involved in a variety of opportunistic infections. Multi-locus sequence-typing (MLST schemes identified distinct phylotypes associated with health and disease. Being based on 8 to 9 house-keeping genes these MLST schemes have a high discriminatory power, but their application is time- and cost-intensive. Here we describe a single-locus sequence typing (SLST scheme for P. acnes. The target locus was identified with a genome mining approach that took advantage of the availability of representative genome sequences of all known phylotypes of P. acnes. We applied this SLST on a collection of 188 P. acnes strains and demonstrated a resolution comparable to that of existing MLST schemes. Phylogenetic analysis applied to the SLST locus resulted in clustering patterns identical to a reference tree based on core genome sequences. We further demonstrate that SLST can be applied to detect multiple phylotypes in complex microbial communities by a metagenomic pyrosequencing approach. The described SLST strategy may be applied to any bacterial species with a basically clonal population structure to achieve easy typing and mapping of multiple phylotypes in complex microbiotas.

    Acne vulgaris is a chronic inflammatory disease that usually requires systemic treatment for severe forms. Isotretinoin is the most effective drug in the treatment of acne vulgaris. In this study, we aimed to compare the efficacies of intermittent and continuous low-dose isotretinoin regimens in the treatment of moderate acne vulgaris. Sixty patients with moderate acne were included. They were divided into two groups to receive either intermittent or continuous low-dose isotretinoin. All patients were followed up monthly during the treatment period and for at least six months after completion of therapy. There were no statistically significant differences between the two groups regarding improvement rates at the end of treatments. However, reduction rates in mean acne scores at post-treatment controls were in favor of the continuous low-dose group. During the post-treatment follow-up period, three patients in the intermittent group relapsed, while no relapses were observed in the low-dose group. No significant side effects were observed in any groups. Both intermittent and continuous low-dose isotretinoin regimens are very well tolerated and effective as classical regimens in the treatment of moderate acne vulgaris. However, a continuous low-dose regimen seems to be slightly superior in terms of patients' compliance to the treatment and lower risk of relapse. © 2013 The International Society of Dermatology.

    There is no gold standard treatment for facial acne scars, and overall, little literature exists about the combination therapy for treatment of acne scar. The aim of this study was to evaluate the efficacy of fractionated microneedle radiofrequency (FMR) vs FMR combined with subcision for the treatment of atrophic acne scars. This was a randomized, split-face clinical study of 25 patients with II-IV Fitzpatrick skin types with moderate to severe facial atrophic acne scars. Initially, standard subcision by Nokor needle was performed on one side. Two weeks after subcision, FMR treatment was performed on both cheeks of each participant. Second and third FMR treatment sessions were performed within 4-week intervals. Two-blinded dermatologists performed clinical assessments using a quartile grading scale, and patients were also asked to judge their satisfaction using a visual analog scale (VAS) scoring system. The age of the patients varied from 24 to 40 years (mean: 30.08±4.94 years). Only nine patients (36%) were males. Clinical assessment by two-blinded dermatologists showed statistically significant improvement in the combination (FMR+subcision) group (P=.009). Patient satisfaction was statistically significantly better in the combination group (P=.001). A darkening of skin phototype was associated with a decrease in patient's satisfaction VAS score (P=.07). The combination of subcision and FMR is a safe and effective modality for mixed type acne scars. Additional randomized clinical study with long-term follow-up is necessary for further evaluation of FMR in combination with other procedures.

    Acne vulgaris, an inflammatory skin disease with different clinical appearances, is a common problem in most adolescents. It seems that using combinations of topical agents can decrease resistance to the treatment and improve the efficacy. Therefore, we evaluated the effects of azelaic acid (AA) 5% and clindamycin (Clin) 2% combination (AA-Clin) on mild-to-moderate acne vulgaris. The efficacy and safety of 12-week treatment with AA-Clin in patients with mild-to-moderate facial acne vulgaris were evaluated by a multicenter, randomized, and double-blind study. A total of 88 male and 62 female patients were randomly assigned to one of these treatments: AA 5%, Clin 2%, and combination of them. Every 4 weeks, total inflammatory and noninflammatory lesions were counted, acne severity index (ASI) was calculated, and patient satisfaction was recorded. Treatment for 12 weeks with combination gel significantly reduced the total lesion number compared with baseline (p < 0.01), as well as Clin 2% or AA 5% treatment groups (p < 0.05 or p < 0.01). The percentage of reduction in ASI in combination treated group (64.16 ± 6.01) was significantly more than those in the Clin 2% (47.73 ± 6.62, p < 0.05) and 5% AA (32.46 ± 5.27, p < 0.01) groups after 12 weeks. Among the patients in the AA-Clin group, 75.86% of males were satisfied or very satisfied and 85.71% of females were satisfied or very satisfied. This trend was significant in comparison to the number of patients who were satisfied with AA 5% or Clin 2% treatment (p < 0.01). Seven patients in AA-Clin group (incidence = 22%) showed adverse effects that were not statistically significant compared to treatment with individual active ingredients. The profound reduction in lesion count and ASI by combination therapy with AA-Clin gel in comparison to individual treatment with 5% AA or Clin 2% suggested the combination formula as an effective alternative in treatment of acne vulgaris.

    There is a paucity of studies on the use of chemical peels for acne scars among the Asian population. A trichloroacetic acid (TCA) and Jessner's combination chemical peel, originally described by Monheit, is said to be better than a TCA peel alone. The aim of the study was to compare the efficacy of 20% TCA and Jessner's solution versus 20% TCA alone for the treatment of acne scars. : The patients were divided into two groups of 25 patients each. Chemical peeling was done in both the groups. In Group I, chemical peeling with Jessner's peel followed by 20% TCA was done and in Group II patients chemical peeling with 20% TCA peel alone was done. In Group I (Jessner's peel and 20% TCA), mild improvement of acne scars was seen in 8% cases, moderate improvement in 32% cases and marked improvement of acne scars was seen in 60% patients. In Group II (20% TCA), mild improvement of acne scars was seen in 32% cases, moderate improvement in 40% cases and marked improvement of acne scars was seen in 28% patients. But, the difference in improvement of acne scars was not statistically significant in both the groups (P value > 0.05).

    Full Text Available Background: Photodynamic therapy (PDT has been shown to be an effective alternative for acne. However, there is little information comparing the efficacy of red light alone and methyl aminolaevulinate (MAL-PDT. Aims: To compare the efficacy and tolerability of red light alone and MAL-PDT in patients with mild to moderate facial acne. Methods: Thirty six patients with mild to moderate acne were enrolled. Eighteen patients recieved MAL-PDT and 18 received red light alone in two sessions, 2 weeks apart. Acne grade and lesion counts were assessed by blinded evaluators at baseline, 2, 4 and 10 weeks. Results: At week 2, clinical improvement from acne grade II-IV to 0-I was observed in 82.3% of MAL-PDT group and 14.2% of red light alone group. Red light alone group had a gradual clinical improvement over time with a 77% response at week 10. In contrast, MAL-PDT group had a rapid clinical improvement with total response at week 10. Both treatments were significantly effective for improving acne lesions. However, MAL-PDT group had a greater response (P < 0.001. Histologically, decreased amounts of sebocytes and lipids along with atrophic sebaceous glands were observed after MAL-PDT. Conclusion: MAL-PDT has a quicker onset of action with a higher response than red light alone. MAL-PDT may induce a reduction in the size of the sebaceous glands and then long-term acne remission.

    To investigate the efficacy and safety of low-concentration 5-aminolevulinic acid photodynamic therapy (ALA-PDT) in the treatment of different severity of acne vulgaris and optimize the treatment regimen. A self-controlled multicenter clinical trial was carried out in 15 centers throughout China. A total of 397 acne patients of grade II-IV received 3- or 4-session PDT treatment. 5% ALA gel was applied topically to acne lesions for 1h incubation. The lesions were irradiated by a LED light of 633 nm at dose levels of 96-120 J/cm(2). Clinical assessment was conducted before and after every treatment up to 8 weeks. The effective rate overall and of grade II, III and IV are 82.1%, 71.6%, 79.6% and 88.2%, respectively. The effective rate rises significantly proportionally to the severity of acne (P0.05). The count of inflammatory and non-inflammatory acne lesions gradually decrease after each treatment (Pacne vulgaris in Chinese patients. Superior efficacy is found in severe cystic acne of grade IV with mild side effects. Copyright © 2013 Elsevier B.V. All rights reserved.

    Acne vulgaris is a common problem, particularly among adolescents, which is usually resistant to monotherapy. We evaluated the efficacy and safety of a combination of azelaic acid (AA) 5% and erythromycin 2% gel (AzE) compared with AA 20% or erythromycin 2% gels in facial acne vulgaris. We conducted a 12-week, multicenter, randomized double-blind study on 147 patients with mild-to-moderate acne vulgaris. Four treatment group were determined (placebo, erythromycin, AA and AzE) and followed in 4-week intervals for 12 weeks, except the placebo group which was changed to routine treatment after 4 weeks. The combination of AA 5% and erythromycin 2% gel significantly reduced the number of papules, pustules and comedones compared with placebo (p < 0.001), erythromycin 2% (p < 0.01) or AA 20% (p < 0.05). The incidence of adverse effects observed in patients treated with AzE (27%) was less than that with erythromycin 2% (54%) and AA 20% (45%). The combination of AA 5% and erythromycin 2% produced more potent therapeutic effects in comparison with erythromycin 2% or AA 20% alone, and with fewer side effects.

    Acne vulgaris is common in Asian populations. We compared three methods of phototherapy for the treatment of moderate to severe facial acne vulgaris in Chinese patients. Patients were randomly assigned to receive photodynamic therapy (PDT), intense pulsed light (IPL) or blue-red light-emitting diode (LED) phototherapy to the right side of the face until the inflammatory lesion count reduced by ≥ 90%. Patients were examined at 1 and 3 months after the final treatment. We enrolled 150 patients (92 males; mean age, 28 years). At 1 month, ≥90% clearance or moderate improvement occurred in 46/50 (92%), 29/50 (58%) and 22/50 (44%) patients in the PDT, IPL and LED groups, respectively (mean number of sessions required, PDT: 3 ± 1.52; IPL: 6 ± 2.15; LED: 9 ± 3.34). Forty-six (92%) patients experienced mild to moderate pain, erythema and edema after PDT, which resolved within 5-7 days. Slight erythema and stinging were reported immediately after IPL and LED, resolving within 2 h. After 3 months, minimal papules and pustules were observed in 4 patients in the PDT group, 7 in the IPL group and 12 in the LED group, but no nodular pustules recurred.

    The 585-nm pulsed-dye laser and the 1,450-nm diode laser have been found effective for the treatment of mild-to-moderate inflammatory facial acne. This study was designed to evaluate the efficacy and safety of the combined treatment with the 595-nm pulsed-dye laser and the 1,450-nm diode laser for inflammatory facial acne. Fifteen patients with inflammatory facial acne were treated with a combination of the 595-nm pulsed-dye laser and the 1,450-nm diode laser. Patients' subjective response to treatment was evaluated regarding improvement in acne, acne scarring, oiliness, and redness of the skin. All patients had reductions in acne lesion counts. Mean lesion counts decreased 52% (P < 0.01), 63% (P < 0.01), and 84% (P < 0.01) after one, two, and three treatments, respectively. Patients described moderate-to-marked improvement in acne, acne scarring, and post-inflammatory erythema. Adverse effects were limited to mild, transient erythema. The combination of the 595-nm pulsed-dye laser and the 1,450-nm diode laser is safe and effective for the treatment of inflammatory facial acne, acne scarring, and post-inflammatory erythema. 2005 Wiley-Liss, Inc.

    While device-based acne treatments are widely applied for patients not tolerating conventional medications, related controlled studies have been still limited. Recently, non-ablative 1450-nm diode laser (DL) and fractional microneedling radiofrequency (FMR) have been effectively used for acne, in addition to well-recognized dermal remodelling effects. To compare the clinical course of acne treatment between DL and FMR. Twenty-five Korean patients with mild-to-moderate facial acne completed treatments with DL and FMR through a 20-week, randomized split-face study. One randomly assigned half side of each patient's face received DL and the other side by FMR. Treatments were scheduled to receive three consecutive sessions at 4-week intervals. Objective assessments including revised Leeds grades, lesion counts, sebum output measurements, and patients' subjective satisfaction were investigated. Both DL and FMR demonstrated steady improvement of acne and seborrhoea during treatment sessions. While results between two devices were similar during treatment sessions, FMR was superior to DL in the 12-week follow-up. Patients' subjective assessments for seborrhoea improvement were similar between two devices, while those for acne, skin texture, and acne scars were more satisfactory for FMR. For safety profile, no significant difference was observed between two regimens, while mild postinflammatory hyperpigmentation was observed only in DL side. Both DL and FMR demonstrated efficacies for acne and seborrhoea, with reasonable safety profile. FMR was more effective than DL for the long-term maintenance, and subjective assessments for texture and scar improvements. Therefore, a few sessions of these devices would be a viable option for acne treatments. © 2017 European Academy of Dermatology and Venereology.

    Several treatment modalities are used for the treatment of acne scars with variable results. Recent studies showed that fractional radiofrequency may be an effective treatment modality for acne scars. The objective of this study was to assess the efficacy, safety, tolerability and patient satisfaction of fractional bipolar radiofrequency (RF), the eTwo™ system (Syneron Candela Ltd., Yokneam, Israel) for treating acne scars. Twelve patients with moderate to severe acne scars received 3-5 treatments with the Sublative fractionated bipolar RF applicator of the eTwo device at 1-month intervals. Patients were evaluated clinically and photographically at each visit and 3 months after the final treatment. Very good improvement (at least one scale) was seen after completing the five treatments. The patient satisfaction survey (Global Aesthetic Improvement Scale scores) revealed that half (6 out of 12) of the patients reported to be satisfied with treatment results, while the other half reported to be very satisfied. Beyond the expected erythema and minimal scab formation in the treated areas, which was mild and transient, none of the participants reported any adverse events. The data presented here support the high efficacy and safety of fractionated bipolar RF for the aesthetic improvement of moderate to severe acne scars. © 2015 Wiley Periodicals, Inc.

    Acne vulgaris treatments usually cause sensitivity, teratogenicity and bacterial resistance. Investigations of other therapeutic techniques, such as phototherapy, are highly relevant. Thus, we compared the effectiveness of two Acne vulgaris treatments in adolescents: peeling with salicylic acid (SA) and phototherapy. Teens were randomly divided into: group I, treatment with SA peels (10%) and group II, treatment with phototherapy (blue LED and red laser lights). Photographs were taken before and after ten sessions of each treatment, carried out weekly, and compared. To compare the differences between the treatments, the Student t-test was used. P values phototherapy showed a significant difference in reducing the number of pustules. The combined use of red and blue lights due to their anti-inflammatory and wound-healing properties is a more efficient alternative for treating Acne vulgaris in relation to SA and proves more reliable and without side effects, improving the adolescents' skin health.

    Topical therapy is the first choice for the treatment of mild to moderate acne and all-trans retinoic acid is one of the most used drugs. The combination of retinoids and antimicrobials is an innovative approach for acne therapy. Recently, lauric acid, a saturated fatty acid, has shown strong antimicrobial activity against Propionibacterium acnes. However, topical application of retinoic acid is followed by high incidence of side-effects, including erythema and irritation. Solid lipid nanoparticles represent an alternative to overcome these side-effects. This work aims to develop solid lipid nanoparticles loaded with retinoic acid and lauric acid and evaluate their antibacterial activity. The influence of lipophilic stearylamine on the characteristics of solid lipid nanoparticles was investigated. Solid lipid nanoparticles were characterized for size, zeta potential, encapsulation efficiency, differential scanning calorimetry and X-ray diffraction. The in vitro inhibitory activity of retinoic acid-lauric acid-loaded solid lipid nanoparticles was evaluated against Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis. High encapsulation efficiency was obtained at initial time (94 ± 7% and 100 ± 4% for retinoic acid and lauric acid, respectively) and it was demonstrated that lauric acid-loaded-solid lipid nanoparticles provided the incorporation of retinoic acid. However, the presence of stearylamine is necessary to ensure stability of encapsulation. Moreover, retinoic acid-lauric acid-loaded solid lipid nanoparticles showed growth inhibitory activity against Staphylococcus epidermidis, Propionibacterium acnes and Staphylococcus aureus, representing an interesting alternative for the topical therapy of acne vulgaris.

    Acne is a prevalent, chronic, and sometimes severe skin disorder affecting an estimated 85% of adolescents and 50% of adults older than age 20 years. The psychosocial implications of acne can be considerable, often continuing long after physical symptoms resolve. Although effective acne medications are available, most exhibit adverse-effect profiles that can leave the patient with few effective treatment options. Emerging evidence indicates that plant-derived essential oils may be a biologically plausible treatment for acne, although high-quality evidence of effectiveness and safety is lacking. To examine the clinical effectiveness and cost-effectiveness of essential oils and aromatherapy for the treatment of acne. This randomized, wait-list controlled trial will have three parallel groups; 192 participants with acne vulgaris, aged 16-45 years, will be recruited primarily through eight Technical and Further Education campuses across Adelaide, South Australia. Participants will be randomly assigned to standard essential oil blend, customized aromatherapy treatment, or wait-list control. Changes in the physical and psychosocial symptoms of acne will be assessed at baseline and 6 and 12 weeks by using the Leeds Acne Grading System, Assessment of Quality of Life-8 Dimension instrument, and Acne-Specific Quality of Life instrument. Costs of treatment will be measured on the basis of resource inputs and unit costs and will be limited to acne treatment. The clinical effectiveness and cost-effectiveness will be compared between each intervention and against usual care, using standard health economic techniques. The provision of high-quality evidence of the effectiveness of essential oils and aromatherapy in the treatment of acne may help consumers make better-informed choices about acne management. Insights gained from this research will also contribute to the academic field of complementary medicine, specifically aromatherapy, for which the evidence base is extremely

    Azelaic acid (AzA) 15% gel is approved for the treatment of rosacea in the US, but also has approval for the treatment of acne vulgaris in many European countries where it has demonstrated success. Two randomized, multicenter, controlled clinical trials compared the effects of AzA 15% gel with those of topical benzoyl peroxide 5% or topical clindamycin 1%, all using a twice-daily dosing regimen. The primary endpoint in the intent-to-treat analysis was a reduction in inflammatory papules and pustules. AzA 15% gel resulted in a 70% to 71% median reduction of facial papules and pustules compared with a 77% reduction with benzoyl peroxide 5% gel and a 63% reduction with clindamycin. AzA 15% gel was well-tolerated. In addition, a 1-year European observational study conducted by dermatologists in private practice evaluated the safety and efficacy of AzA 15% gel used as monotherapy or in combination with other agents in more than 1200 patients with acne. Most physicians (81.9%) described an improvement in patients' symptoms after an average of 34.6 days, and 93.9% of physicians reported patient improvement after an average of 73.1 days. Both physicians and patients assessed AzA 15% gel to be effective with 74% of patients being "very satisfied" at the end of therapy. AzA 15% gel was considered "well-tolerated" or "very well-tolerated" by 95.7% of patients. The majority of patients were more satisfied with AzA than with previous therapies. AzA 15% gel represents a new therapeutic option for the treatment of acne vulgaris.

    Fractional technology overcomes the problems of ablative lasers, such as inaccurate depth control and damage to the epidermis. Minimally invasive fractional radiofrequency microneedle devices allow for more-selective heating of the dermis. To evaluate the clinical efficacy of fractional radiofrequency microneedle (ERM) treatment in acne scars and large facial pores. Thirty patients with acne scars and large facial pores were enrolled. Bipolar radiofrequency energy was delivered to the skin through the electrodes of the FRM device. Skin lesions were evaluated according to grade of acne scars, Investigator Global Assessment of large pores, skin surface roughness, transepidermal water loss (TEWL), dermal density, microscopic and composite image, sebum measurement, and questionnaires regarding patient satisfaction. The grade of acne scars and Investigator Global Assessment of large pores improved in more than 70% of all patients. Skin surface roughness, dermal density, and microscopic and composite images also improved, whereas TEWL and sebum measurement did not change. Clinical improvement from FRM treatment appeared to be related to dermal matrix regeneration. FRM treatment may be effective in improving acne scars and facial pores. © 2012 by the American Society for Dermatologic Surgery, Inc. Published by Wiley Periodicals, Inc.

    Acne vulgaris is a common and chronic skin disease, and is a frequent source of morbidity for affected patients. Treatment of acne vulgaris is often difficult due to the multifactorial nature of this disease. Combination therapy, such as that containing clindamycin and benzoyl peroxide, has become the standard of care. Several fixed formulations of clindamycin 1% and benzoyl peroxide of varying concentrations are available and have been used with considerable success. The major limitation is irritation and dryness from higher concentrations of benzoyl peroxide, and a combination providing optimal efficacy and tolerability has yet to be determined. Recently, a clindamycin and benzoyl peroxide 3.75% fixed combination formulation was developed. Studies have suggested that this formulation may be a safe and effective treatment regimen for patients with acne vulgaris. Here, we provide a brief review of acne pathogenesis, benzoyl peroxide and clindamycin, and profile a new Clindamycin-BP 3.75% fixed combination gel for the treatment of moderate-to-severe acne vulgaris.

    Acne is still a major problem, and treatment options are far from ideal. A number of studies suggest that the species Propionibacterium acnes plays an important role in the pathogenesis, and new data point towards molecular mechanisms by which the organism is able to trigger the host inflammatory...... response. The current knowledge on P. acnes in relation to acne is reviewed....

    There is a need for additional effective treatments for acne vulgaris. Laser therapy has been explored as a therapeutic option for acne, but rigorously designed studies in this area have been limited. We sought to examine the efficacy of an infrared laser in the treatment of acne. We conducted a randomized, controlled, single-blind, split-face clinical trial of 46 patients with facial acne. Patients received a series of 3 nonablative laser treatments using a novel neodymium:yttrium-aluminum-garnet (Nd:YAG) laser to half of the face. Serial blinded lesion counts and global acne severity rating of standardized bilateral patient photographs were performed. Sebum production was measured, and patient self-assessment surveys were administered. A transient but statistically significant improvement in lesion counts of open comedones was demonstrated in treated skin as compared with untreated skin. There were no significant differences between treated and control sides of the face in terms of changes in mean papule or pustule counts. Grading of serial photographs revealed no significant differences between treated and untreated skin. Patient surveys indicated that the majority of patients found the treatments to be at least mildly effective for both acne and oiliness. The current study only addresses the efficacy of a single laser system employing a specific treatment regimen. Infrared laser therapy may improve comedonal acne. Additional work is needed to better define the degree and duration of the effect. Patients appear to positively view such therapy for both acne and oily skin.

    Full Text Available Introduction: Topical antibiotics are the main step in the treatment of mild to moderate acne vulgaris. Erythromycin is one of the effective topical therapies for this disease. Zinc sulfate 5% solution was reported to be effective in treatment of acne vulgaris and rosacea. Aim: To compare the effectiveness and side effects of topical erythromycin in combination with zinc and erythromycin alone in treatment of mild to moderate acne vulgaris. Material and Methods: This single, blind, therapeutic, comparative study was done in the Department of Dermatology – Baghdad Teaching Hospital, Baghdad, Iraq; from May 2012 – August 2013.Scoring of acne was carried out and the patients were examined every two weeks for 10 weeks of treatment. One month after stopping drugs, patients were evaluated for drug complications and disease recurrence. Eighty patients fulfilling enrollment criteria were included in this study. Patients were divided into two groups: Group A (40 patients treated twice daily with topical erythromycin-zinc complex lotion and Group B (40 patients treated twice daily with topical 2% erythromycin gel. Results: Both topical erythromycin-zinc lotion and erythromycin gel were statistically an effective therapy starting after 6 weeks treatment and up to 4 weeks after stopping treatment. Erythromycin-zinc lotion was more effective and act earlier than erythromycin gel starting from 4 weeks of therapy till the end of treatment (after 10 week and even after 4 weeks after stopping the treatment (p value <0.0001. Conclusions: Erythromycin-zinc complex lotion was an effective and well tolerated topical therapy for mild to moderate inflammatory acne vulgaris and was more effective than erythromycin gel alone.

    Topical dapsone 5% gel for the treatment of mild to moderate acne has been shown to be effective in randomized controlled studies. A total of 101 adult women with mild to moderate facial inflammatory acne participated in a 12-week cohort study to evaluate the efficacy, tolerability, and safety of dapsone gel 5% in this specific group who often complain of sensitive skin. The women were instructed to apply dapsone 5% gel twice daily after washing their face with a standard noncomedogenic soap-free cleanser. Treatment outcome was evaluated using physician-scored Global Acne Assessment Scale (GAAS) and patient-reported facial skin condition. Ninety-three women completed the study (6 were lost to follow-up and 2 had mild skin irritation). At 12 weeks, significant physician GAAS scores (t55 = 8.85, P = .001) and patient-reported lesion reductions were shown. Treatment success (GAAS 0 or 1) at 12 weeks was achieved in 69.4% (n = 75) of women (t94 = 4.17, P = .001), improving patient-reported quality-of-life aspects. Topical dapsone gel 5% was shown to be safe, minimally irritating, and effective in the treatment of mild to moderate inflammatory facial acne in adult women with sensitive skin.

    Conclusions. Hormonal study of women with acne should include an assessment of the function of ovaries, adrenal glands, thyroid gland, determination of the level of prolactin in the blood plasma and glycated hemoglobin. Treatment should be aimed at management of hormonal and metabolic disorders, and topical treatment of acne. Before 30 years of age it is important to diagnose polycystic ovary syndrome and late forms of congenital dysfunction of the adrenal glands, after 30 — hyperprolactinemia syndrome, hypothyroidism, diabetes mellitus type 2, and after 40 years acne often manifests on the background of ovarian failure.

    The relationship between the subjective skin type and the casual sebum level was not fully clarified. To investigate the characteristics of subjective skin type and to find the relationship between the subjective skin types and the skin type-related symptoms, casual sebum level, along with the objective skin type. Seven hundred and nine patients, clinically diagnosed with acne, were included. The questionnaire and the casual sebum level measurement were performed. The determining symptoms of each subjective skin type were investigated. The 95% confidence interval of casual sebum level of each subjective skin type was calculated. The most frequent subjective skin type was the combination type. The dryness, tightness, and oiliness can be conclusive symptoms in determining the subjective skin type. The mean and the 95% confidence interval of the casual sebum level was highest in the oily skin type, followed by the combination, normal, and dry skin type. We found that the subjective skin type was determined by the skin type-related symptoms. The 95% confidence intervals of the casual sebum level of each subjective skin type were established. Based on the skin type-related symptoms, the casual sebum level of acne patients can be estimated. © 2012 John Wiley & Sons A/S. Published by Blackwell Publishing Ltd.

    Acne is a prominent skin condition affecting >80% of teenagers and young adults and ~650 million people globally. Isotretinoin, a vitamin A derivative, is currently the standard of care for treatment. However, it has a well-established teratogenic activity, a reason for the development of novel and low-risk treatment options for acne. To investigate the effectiveness of Zolav(®), (a p-carboethoxy-tristyrylbenzene derivative) [corrected] a novel antibiotic as a treatment for acne vulgaris. Minimum inhibitory concentration of Zolav(®) (a p-carboethoxy-tristyrylbenzene derivative) against Propionibacterium acnes was determined by following a standard protocol using Mueller-Hinton broth and serial dilutions in a 96-well plate. Cytotoxicity effects on human umbilical vein endothelial cells and lung cells in the presence of Zolav(®) (a p-carboethoxy-tristyrylbenzene derivative) were investigated by determining the growth inhibition (GI50) concentration, total growth inhibition concentration, and the lethal concentration of 50% (LC50). The tryptophan auxotrophic mutant of Escherichia coli strain, WP2 uvrA (ATCC 49979), was used for the AMES assay with the addition of Zolav(®) (a p-carboethoxy-tristyrylbenzene derivative) tested for its ability to reverse the mutation and induce bacterial growth. The in vivo effectiveness of Zolav(®) (a p-carboethoxy-tristyrylbenzene derivative) was tested in a P. acnes mouse intradermal model where the skin at the infection site was removed, homogenized, and subjected to colony-forming unit (CFU) counts. Susceptibility testing of Zolav(®) (a p-carboethoxy-tristyrylbenzene derivative) against P. acnes showed a minimum inhibitory concentration of 2 µg/mL against three strains with no cytotoxicity and no mutagenicity observed at the highest concentrations tested, 30 µM and 1,500 µg/plate, respectively. The use of Zolav(®) (a p-carboethoxy-tristyrylbenzene derivative) at a concentration of 50 µg/mL (q8h) elicited a two

  5. Over a Decade of recA and tly Gene Sequence Typing of the Skin Bacterium Propionibacterium acnes: What Have We Learnt?

    Full Text Available The Gram-positive, anaerobic bacterium Propionibacterium acnes forms part of the normal microbiota on human skin and mucosal surfaces. While normally associated with skin health, P. acnes is also an opportunistic pathogen linked with a range of human infections and clinical conditions. Over the last decade, our knowledge of the intraspecies phylogenetics and taxonomy of this bacterium has increased tremendously due to the introduction of DNA typing schemes based on single and multiple gene loci, as well as whole genomes. Furthermore, this work has led to the identification of specific lineages associated with skin health and human disease. In this review we will look back at the introduction of DNA sequence typing of P. acnes based on recA and tly loci, and then describe how these methods provided a basic understanding of the population genetic structure of the bacterium, and even helped characterize the grapevine-associated lineage of P. acnes, known as P. acnes type Zappe, which appears to have undergone a host switch from humans-to-plants. Particular limitations of recA and tly sequence typing will also be presented, as well as a detailed discussion of more recent, higher resolution, DNA-based methods to type P. acnes and investigate its evolutionary history in greater detail.

    The Internet provides both education and miseducation for acne patients. Although some sites provide disease background information and objective treatment guidance, support networks, and research findings, others may seem to be objective on the surface, but are in reality run by untrained, self-proclaimed experts or are promotional in nature. Providers must be aware of the potential benefits and pitfalls the Internet provides for those suffering with acne. Copyright © 2016 Elsevier Inc. All rights reserved.

    The strong bactericidal properties of lauric acid (C12:0), a middle chain-free fatty acid commonly found in natural products, have been shown in a number of studies. However, it has not been demonstrated whether lauric acid can be used for acne treatment as a natural antibiotic against Propionibacterium acnes (P. acnes), which promotes follicular inflammation (inflammatory acne). This study evaluated the antimicrobial property of lauric acid against P. acnes both in vitro and in vivo. Incubat...

    Acne and rosacea are common chronic inflammatory skin diseases. During pregnancy these skin disorders may become aggravated, in rare cases occurring for the first time. There are no data available for rosacea and little data for acne concerning the course of these skin disorders during pregnancy. Up to 42% of the pregnant women suffer from acne. In 90% of these women the disease existed before pregnancy. In 1/3, however, acne relapsed during pregnancy after a prior disease-free period. In 60% acne deteriorated during pregnancy. Randomized controlled trials for the treatment of acne or rosacea during pregnancy do not exist. In this article the recommendations of current guidelines are modified, so that effective treatments can be recommended without harming the embryo or fetus.

    Full Text Available Acne vulgaris is a very common chronic inflammatory disease of pilosebaceous units. It can be associated with considerable loss of self-esteem and psychological morbidity when left untreated. With the emergence of lasers and intense pulsed light, long-term reduction of acne lesions is now possible. The success of these optical devices depends on the selected parameters and biologic variables of patient. The objective of this study is to determine the efficacy and safety of intense pulsed light (IPL in the treatment of mild-to-moderate acne vulgaris. This interventional study was conducted for a period of one year after approval of synopsis. A total of 75 patients of mild-to-moderate acne vulgaris were included through non-probability, convenience sampling. Patients were subjected to intense pulsed light (IPL therapy once a week for four weeks. Digital photography was done at the baseline and at the sixth week. Follow-up was done after two weeks of completion of four sessions. Repeated measurement ANOVA was used for significance of IPL at six weeks of follow-up. The p value 50% reduction with therapy. Percentage reduction was observed as 49 ± 20% at final follow-up. Papules count was reduced from 11.95 ± 2.89 to 6.69 ± 2.96, pustules count was reduced from 2.55 ± 1.54 to 0.79 ± 1.02 from baseline to final follow-up visit. 16 subjects showed mild erythema that resolved within 24 h. None of the patients showed any severe side effects at final follow-up visit. We conclude from the results of this study that IPL is safe and efficacious in more than half of the patients in the treatment of mild and moderate acne vulgaris. A long-term follow-up is required to determine long-term safety on skin following such procedures.

    Acne scars can be improved with various treatments such as topical creams, chemical peels, dermal fillers, microdermabrasion, laser, and radiofrequency devices. Some of these treatments especially lasers and deep chemical peels can have significant side effects such as post inflammatory hyperpigmentation in darker skin types. Fraxelated RF Laser devices have been reported to have lower incidence of side effects in all skin phototypes. Nine patients between ages 18 and 35 of various skin phototypes were selected from a private practice and treated with a RF fraxelated device (E-matrix) for acne scars. Outcomes were measured by physician observation, subjective feedback received by patients, and comparison of before and after photographs. In this small group of patients with various skin phototypes, fraxelated radiofrequency device improved acne scars with minimal side effects and downtime.

    This study evaluates the efficacy and safety of a novel fractional CO(2) laser device for improving facial rhytids, hyperpigmentation, enlarged pores, skin laxity, and acne scarring. Subjects (n= 15) were treated three to five times at 3-week intervals. Biopsy specimens were used to evaluate healing response and neocollagenesis. Clinical improvement was rated on a quartile rating scale from digital photographs. Subject discomfort during treatment was evaluated on a scale of 0 to 5. Fourteen subjects who completed the study achieved good to excellent improvement in overall appearance, with 60% rated excellent. Improvement in photodamage was good to excellent in 92% of subjects, and reduction in rhytids was good to excellent in 85%. A total of 79% of subjects achieved good to excellent improvement in pore sizes and skin laxity. Subject discomfort during treatment was 3.0 +/- 0.7. Erythema persisted for 2-3 days, and subjects resumed normal activities 1-2 days after the procedure. Histological slides after a single treatment showed new collagen formation. The SmartSkin fractional CO(2) system (Cynosure, Inc., Westford, MA, USA) provides significant improvement for the treatment of facial wrinkles, hyperpigmentation, pore size, and skin laxity associated with photodamage.

Its onset in adolescence may add to the emotional and psychological challenges experienced during this period. To assess the impact of acne on the various psychosocial domains of daily life. This was a prospective, cross-sectional study done in the dermatology out-patient department of a tertiary care hospital from January to March 2015. A total of 100 consecutive, newly diagnosed patients of acne vulgaris, aged 15 years and above were included in this study. The relationship between acne vulgaris and its sequelae was analyzed with ten different domains of daily life by using dermatology life quality index (DLQI) questionnaire. Females (56%), 15-20 year olds (61%), facial lesions (60%), and Grade II acne (70%) were most common. Acne scars were noted in 75% patients, whereas 79% cases had post-acne hyperpigmentation. Thirty-seven percent patients had DLQI scores of (6-10) interpreted as moderate effect on patient's life. Statistically significant correlation (P < 0.05) found were as follows: Physical symptoms with grade of acne; embarrassment with site and grade of acne; daily activities with grade of acne and post-acne pigmentation; choice of clothes with site of acne; social activities with gender, site and grade of acne; effect on work/study with grade of acne; interpersonal problems with site and post-acne pigmentation; sexual difficulties with grade of acne. It was a hospital-based study with small sample size. Significant impact of acne and its sequelae was noted on emotions, daily activities, social activities, study/work, and interpersonal relationships. Assurance and counseling along with early treatment of acne vulgaris is important to reduce disease-related psychosocial sequelae and increase the efficacy of treatment.

    Antimicrobial peptides are considered as a potential alternative to antibiotic treatment in acne vulgaris because the development of a resistant strain of Propionibacterium acnes is problematic. Granulysin can be regarded as an ideal substance with which to treat acne because it has antimicrobial and anti-inflammatory effects. This study was performed to explore the effectiveness of granulysin-derived peptides (GDPs) in killing P. acnes in vitro under a standard microbiologic assay and to evaluate their potential use in a topical agent for the treatment of acne vulgaris. Twenty different peptides based on the known sequence of a GDP were synthesized and tested in vitro for antimicrobial activity. Thirty patients with facial acne vulgaris were instructed to apply a topical formulation containing synthetic GDP to acne lesions twice per day for 12 weeks. A newly synthesized peptide in which aspartic acid was substituted with arginine, and methionine was substituted with cysteine, showed the highest antimicrobial activity against P. acnes. Moreover, it was effective against both Gram-positive and Gram-negative bacteria in vitro. After treatment with the topical formulation containing 50 ppm of synthetic peptide for 12 weeks, a significant reduction in the number of pustules was observed, regardless of the increase in the number of comedones. In addition, a significant reduction in the clinical grade of acne based on the Korean Acne Grading System (KAGS) was evident. Synthesized GDP shows strong antimicrobial activity against P. acnes in vitro. The clinical improvement observed suggests a topical formulation containing the GDP has therapeutic potential for the improvement of inflammatory-type acne vulgaris by its antimicrobial activity. © 2015 The International Society of Dermatology.

  16. Safety and efficacy of low-dose isotretinoin in the treatment of moderate to severe acne vulgaris

    Parinitha K Rao

    2014-01-01

    Full Text Available Background: Isotretinoin is indicated for moderate to severe cases of acne which are unresponsive to conventional therapy. The classical recommended dose is 0.5 to 1.0 mg/kg/day. As the side effects are dose related, low-dose isotretinoin therapy for acne is an attractive option; however, but little data exists on the safety and efficacy of this strategy. Materials and Methods: In this prospective, non-comparative study, 50 participants, both male and female, having moderate to severe acne vulgaris were enrolled and treated with isotretinoin at a dose of 20 mg/day (approximately 0.3-0.4 mg/kg/day, for a period of 3 months. Participants were evaluated by means of clinical and laboratory investigations before starting isotretinoin. Investigations were repeated at the end of the first and third months following completion of treatment, and participants were followed up for 6 months to look for any relapse. Results: At the end of the treatment, very good results were observed in 90% of participants. Cheilitis was the most common among the side effects observed and was seen in 98% of the participants. One participant developed vitiligo as a side effect, which is a new finding, and has not reported in literature before. Elevated serum lipid levels were observed in 6% of the participants, and relapse occurred in 4% of the participants over a 6 month follow up period. Conclusion: Three months of treatment with low-dose isotretinoin (20 mg/day was found to be effective in the treatment of moderate to severe acne vulgaris, with a low incidence of serious side effects. This dose also was more economical than the higher doses.

    An 18-year-old Japanese girl had received oral minocycline 200mg daily for treatment of acne vulgaris since 16 years old. She had a fever three months before admission, followed by joint pains in her knees, elbows and several proximal interphalangeal joints one month before admission. She was referred to our hospital because of a high serum level of anti-DNA antibody. She had already discontinued oral minocycline five weeks before admission, because she missed her medication refilled. On admission, the arthralgia and fever spontaneously resolved, and there were no laboratory evidence of hypocomplementemia and cytopenia. She had neither erythema nor internal organ involvements. Because her symptoms subsided spontaneously after the cessation of minocycline, she was considered to have drug-induced lupus. Both the arthralgia and fever did not relapse, and anti-ds DNA antibody returned to normal during a follow-up period without treatment. There are few reports of drug-induced lupus caused by minocycline in Japan. This case highlights the importance of considering minocycline-induced lupus.

    To investigate the effects of the 1.54 microm wavelength on active lesions of the face and of the back at the 2-year follow-up. A 1.54 microm erbium:glass laser (Aramis, Quantel Medical, France) was used in combination with contact cooling set at +5 degrees C to treat acne on the face with the following parameters (3 ms, four pulses, 10 J/cm2, 2 Hz, cumulative fluence: 40 J/cm2). The laser spots were adjacent (maximum overlap: 20%) and delivered in rows in order to cover the entire area. Four treatments were performed at 4-week intervals in 25 patients with acne severity greater than 3 on the Burton scale. Acne lesion counts (papules, pustules, nodules, comedones) were performed prior to each treatment, and at 2, 4, 12, 18 and 24 months after the final treatment. Among the 25 patients, three were lost to follow-up, four were retreated. So, 18 patients had acne lesions counts 2 years after the fourth treatment. The mean percent reduction was 71% at the 6-month follow-up, 79% at the 1-year follow-up and 73% at the 2-year follow-up. No side effects were reported. All patients commented that their skin was less prone to oiliness. Biopsies taken after treatment showed progressive rarefaction and miniaturization of sebaceous glands and pilosebaceous follicles without morphologic damage to epidermal and dermal structures. Active acne can be successfully treated by selective dermal heating with a 1.54 microm erbium:glass laser coupled to contact cooling, with no related side effects. Furthermore, this longer follow-up study demonstrates long-term acne clearing. Combined treatments with medications (oral or topical) or light (targeting Propionibacterium acnes) may also improve acne clearance.

    Full Text Available Introduction: There is a paucity of studies on the use of chemical peels for acne scars among the Asian population. A trichloroacetic acid (TCA and Jessner′s combination chemical peel, originally described by Monheit, is said to be better than a TCA peel alone. Aims: The aim of the study was to compare the efficacy of 20% TCA and Jessner′s solution versus 20% TCA alone for the treatment of acne scars. Materials and Methods : The patients were divided into two groups of 25 patients each. Chemical peeling was done in both the groups. In Group I, chemical peeling with Jessner′s peel followed by 20% TCA was done and in Group II patients chemical peeling with 20% TCA peel alone was done.

    Full Text Available Among the current treatments available for acne vulgaris, many widely practiced options lack support from studies at the best level of scientific evidence. The aim of this narrative review was to present the very latest information on topical and systemic treatments for acne vulgaris. Information from systematic reviews and well-designed clinical trials, obtained through a systematic search of the major medical databases, is emphasized. There are important issues regarding the clinical management of acne that still lack consistent grounding in scientific evidence. Among these are the optimum dose and duration of treatment with oral antibiotics that can be given without inducing bacterial resistance, and the safety of oral isotretinoin.

    Both pulsed dye laser and combined 585/1064-nm (sequential dual-wavelength PDL and Nd:YAG) laser improves inflammatory skin disorders including acne vulgaris. To compare the efficacy of 585-nm pulsed dye laser versus sequential dual-wavelength PDL and Nd:YAG in treatment of acne vulgaris. Thirty patients with acne vulgaris were treated by PDL alone on half of the face while contra lateral half was treated by combined 585/1064 nm laser. The study showed that inflammatory acne lesions count was significantly reduced by 82.5% (p 0.0001) on PDL sides and by 83.5% (p 0.00001) on combined 585/1064-nm side after 8 weeks, while reduction of non-inflammatory acne lesions was observed at 8 weeks by 58.4% and 71.5% respectively. However, difference between the two modalities was not statistically significant. PDL and combined PDL/Nd:YAG laser treatment were found to be an effective, safe and well-tolerated treatment option for inflammatory and non-inflammatory acne vulgaris.

    Topical measures are still the mainstay in the therapy of mild-to-moderate acne vulgaris. Azelaic acid 20% in a cream formulation has been established as an efficacious and safe topical drug for 15 years. A new non-alcoholic hydrogel formulation containing 15% azelaic acid was clinically tested against two standard drugs--5% benzoyl peroxide (BPO) and 1% clindamycin. In two independent, randomized, blinded comparative trials 15% azelaic acid gel was clinically tested against 5% benzoyl peroxide (BPO) gel in 351 patients and against 1% clindamycin gel in 229 patients. The drugs were applied b.i.d. for 4 months. Azelaic acid 15% gel proved to be as effective as BPO and clindamycin with median % reduction of the inflamed lesion (papules and pustules) of 70%, and 71% respectively. The azelaic acid gel was well-tolerated, the side effects (local burning and irritation) were distinctly less than with BPO but more pronounced than with clindamycin. Despite these side effects, the treatment was well-accepted by the majority of patients. Azelaic acid gel is an effective topical monotherapy for mild-to-moderate acne vulgaris; its new gel form is an enrichment of acne therapy.

    Fractional photothermolysis with a CO2 laser shows promise in the treatment of photodamaged skin. The purpose of this study was to evaluate a fractional CO2 laser device (SmartSkin, Cynosure, Westford, MA) for the treatment of facial photodamage. Twelve subjects seeking treatment of facial hyperpigmentation, skin laxity, wrinkles and fine lines, enlarged pores and acne scars enrolled in the study. Each subject was treated twice with the SmartSkin device at three- to five-week intervals. Results were evaluated at one week, one month and three months after the final treatment. All 12 subjects completed the study. Physician and subject assessments both indicated that clinical improvements in all photodamage parameters were apparent at one month and persisted at least three months. Improvements in acne scars were noted but not graded. Eleven subjects would recommend the treatment to family and friends. The median pain scores during the initial and final treatments were 2.00 and 2.00, respectively, on a scale of 0-5. Only one adverse effect, facial edema, was judged "probably related to treatment." The SmartSkin fractional laser device improves photodamaged skin for at least three months. The treatment was well tolerated and adverse effects were limited to transient facial edema.

    Full Text Available Abstract: Topical retinoids are considered as the first line therapy in the treatment of acne vulgaris, but they are associated with cutaneous irritation. In this study, isotretinoin-loaded solid lipid nanoparticles(IT-SLN were prepared to treat the mild to moderate acne. Also using IT-SLN would minimize IT adverse effects in comparison to commercial product, Isotrex®. This study was conducted to prepare and characterize IT-SLN and assessing the efficiency of IT-SLN comparing to Isotrex® acne. IT-SLN was prepared using hot high pressure homogenization method.  IT-SLN contained 0.05% IT in 5% of lipid phase (Glyceryl monostearate- GMS and tween 80 (2.5 % w/v was used as surfactant in the aqueous phase. IT-SLN was characterized by particle size analyzing, differential scanning calorimetry and transmission electron microscopy. Encapsulation efficacy was also obtained using spectrophotometry. The efficacy of IT-SLN was evaluated in a randomized, single-blind, parallel-group study and compared with Isotrex®. Forty patients encountered in the study and divided in two groups. Treatment regimen was once-nightly topical administration accompanied with topical administration of clindamycin 2% solution twice a day for 8 weeks. The particle size of IT-SLN was around 60 nm with PDI of 0.4 and zeta potential was about -40 mV. Encapsulation efficacy of IT in SLN in crystalline form was 84±0.21%. IT-SLN produced significantly better treatment than Isotrex® in both non-inflammatory and inflammatory lesions according to its recovery percent after 8 weeks. Also IT-SLN gained better global assessment scores. Our results showed that IT-SLN had higher efficacy than Isotrex® to clear non-inflammatory and inflammatory lesions.

  6. Utilizing non-ablative fractional photothermolysis prior to ALA-photodynamic therapy in the treatment of acne vulgaris: a case series.

    Aminolevulinic acid (ALA) photodynamic therapy (PDT) is an emerging modality in the treatment of acne. While ablative fractional lasers have been used to enhance drug delivery into the epidermis, recent evidence suggests that non-ablative fractional photothermolysis may also improve uptake of ALA. We explored the use of non-ablative 1550 nm laser as a safe alternative in the delivery of ALA prior to red-light PDT for refractory inflammatory and cystic acne. Subjects referred for treatment of acne refractory to several topical and oral regimens, including isotretinoin, were pre-treated with non-ablative fractional photothermolysis (NAFP). This was followed by 20 % ALA application with an incubation time of 1-3 h and then exposure to 50-100 J/cm 2 red light. Follow-up was at 1, 3, and 6 months. In all three cases, patients demonstrated marked reduction in inflammatory lesions. Two subjects had remission of acne after a single combination treatment. Non-ablative fractional laser applied immediately prior to PDT may be used in the treatment of acne with minimal side effects and fewer sessions needed than PDT alone. This may be due to enhanced delivery of ALA from pre-treating the skin with non-ablative fractional photothermolysis.

    Full Text Available Background: Antibiotic resistance is a worldwide problem in acne patients due to regional prescription practices, patient compliance, and genomic variability in Propionibacterium acnes, though the effect of treatment on the resistance has not been comprehensively analyzed. Aims: Our primary objective was to assess the level of antibiotic resistance in the Indian patients and to assess whether there was a difference in the resistance across common treatment groups. Subjects and Methods: A cross-sectional, institutional based study was undertaken and three groups of patients were analyzed, treatment naοve, those on antibiotics and patients on benzoyl peroxide (BPO and/isotretinoin. The follicular content was sampled and the culture was verified with 16S rRNA polymerase chain reaction, genomic sequencing, and pulsed-field gel electrophoresis. Minimum inhibitory concentration (MIC assessment was done for erythromycin (ERY, azithromycin (AZI, clindamycin (CL, tetracycline (TET, doxycycline (DOX, minocycline (MINO, and levofloxacin (LEVO. The four groups of patients were compared for any difference in the resistant strains. Results: Of the 52 P. acnes strains isolated (80 patients, high resistance was observed to AZI (100%, ERY (98%, CL (90.4%, DOX (44.2%, and TETs (30.8%. Low resistance was observed to MINO (1.9% and LEVO (9.6%. Statistical difference was seen in the resistance between CL and TETs; DOX/LEVO and DOX/MINO (P < 0.001. High MIC90 (≥256 μg/ml was seen with CL, macrolides, and TETs; moreover, low MIC90 was observed to DOX (16 μg/ml, MINO (8 μg/ml, and LEVO (4 μg/ml. Though the treatment group with isotretinoin/BPO had the least number of resistant strains there was no statistical difference in the antibiotic resistance among the various groups of patients. Conclusions: High resistance was seen among the P. acnes strains to macrolides-lincosamides (AZI and CL while MINO and LEVO resistance was low.

    Acne vulgaris is one of the most common dermatologic condition especially among adolescents. Acne is related to excess sebum production by sebaceous glands, inflammation both within and adjacent to the comedones, hyperproliferation of Propionibacterium acnes. Some of investigations show association between acne and diet. Milk increases the level of IGF-1 leading to the synthesis of androgen-mediated increases sebum production. Chocolate predispose to hyperglycemia and insulinemia which aggravate of acne vulgaris. High levels of omega-6 fatty acids have been associated with increase of acne in contrast to omega-3 fatty acids, which decrease inflammation. Food have huge impact on development and severity of acne and may exert beneficial effect in the treatment of this disorder.

    This study aimed at evaluating the antiproliferative, antibacterial, and anti-inflammatory properties of an ethanolic myrtle extract (Myrtacine®) in vitro, characterising its potential active compounds (myrtucommulones A and B') by structural analysis, and evaluating their biological activity. Antiproliferative activity was assessed by the BrdU incorporation assay in HaCat keratinocytes and inhibitory and bactericidal activities against P. ACNES strains by measuring the minimal inhibitory concentration (MIC) and D value. Anti-inflammatory effect was evaluated by measuring 6-keto-prostaglandin F1 α and [³H]-arachidonic acid metabolite production in keratinocytes stimulated for inflammation.

    In the adult female, acne is a chronic condition with a substantial negative psychological, social and emotional impact. Based on time of onset, two subtypes of adult female acne are recognized: 'persistent acne' is a continuation of the disease from adolescence, while 'late-onset acne' first presents in adulthood. The morphological characteristics of adult female acne are often distinct from adolescent acne. In adults, inflammatory lesions (particularly papules, pustules and nodules) are generally more prominent on the lower chin, jawline and neck, and comedones are more often closed comedones (micro cysts). Adult acne is mainly mild-to-moderate in severity and may be refractory to treatment. A holistic approach to acne therapy should be taken in adult females, which combines standard treatments with adjunctive therapy and cosmetic use. A number of factors specific to the adult female influence choice of treatment, including the predisposition of older skin to irritation, a possible slow response to treatment, a high likelihood of good adherence, whether of child-bearing age, and the psychosocial impact of the disease. Adherence to therapy should be encouraged through further patient education and a simplified regimen that is tailored to suit the individual patient's needs and lifestyle. This article reviews the specific characteristics of adult female acne, and provides recommendations for acne therapy in this patient group. © 2013 The Authors.

    Despite recommendations to limit the use of oral antibiotics and increasing support for hormonal agents in the treatment of acne, it is unclear whether there have been any significant changes in practice patterns. To characterize changes in prescribing behavior for systemic agents in the treatment of acne in the United States between 2004 and 2013. We conducted a retrospective analysis using the OptumInsight Clinformatics DataMart (Optum, Eden Prairie, MN). The number of courses of spironolactone prescribed per 100 female patients being managed for acne by dermatologists and nondermatologists increased from 2.08 to 8.13 and from 1.43 to 4.09, respectively. The median duration of therapy with oral antibiotics was 126 and 129 days among patients managed by dermatologists and nondermatologists, respectively, and did not change significantly over the study period. The OptumInsight Clinformatics DataMart lacks information on acne severity and clinical outcomes. Additional work to identify patients who would benefit most from alternative therapies such as spironolactone, oral contraceptives, or isotretinoin represents a potential opportunity to improve the care of patients with acne.

    Although a variety of laser/light-based devices have been reported to be effective for the treatment of acne, long-term data on efficacy and safety in the management of moderate and severe inflammatory acne is lacking. The objective of this 12-week clinical trial was to evaluate the efficacy and safety of the KLOX BioPhotonic System, a LED blue light device using specific photo-converter chromophores, in the treatment of moderate to severe acne vulgaris. One patient hemiface was randomly selected to receive 6 weeks of treatment (twice weekly) with the LED light and the photo-converter chromophores whereas the contralateral hemiface was not treated with the BioPhotonic System. All patients were provided with a skin cleanser and a non-comedogenic cream with ultraviolet protection to be used on the entire face during the treatment period. Following completion of the 6-week treatment period, the patient was followed for an additional 6 weeks. Efficacy was assessed through changes in acne severity using the Investigator's Global Assessment (IGA) scale and inflammatory acne lesion counts, both evaluated against baseline at weeks 6 and 12. Safety was assessed through physical exam, vital signs, laboratory evaluations, and physician and patient reporting of adverse events. A reduction of at least two grades in IGA scale severity was demonstrated in 51.7% of patients at week 12. Furthermore, at week 12, subjects with a baseline IGA grade of 3 (moderate) demonstrated a success rate (2 or greater grade drop) of 45.3% whereas patients with a baseline IGA grade of 4 (severe) demonstrated a success rate of 61.1%. Acne inflammatory lesion counts confirmed these results, with a reduction of at least 40% of lesions in 81.6% of treated hemifaces after 12 weeks. Treatment was considered as safe and well tolerated, with no serious adverse event and no patient discontinuation from the study from any adverse event. Patients' quality of life was also improved with a decrease of pain

    Acne vulgaris is a common, chronic skin disease that requires long-term therapy. Oral antibiotics are a mainstay of treatment, but extended use is associated with the development of bacterial resistance. Topical therapies are often combined with oral antibiotics to achieve an initial improvement, after which the oral agents may be discontinued and the topical therapy used as maintenance. To assess the safety and efficacy of combination therapy with dapsone 5% gel with oral doxycycline hyclate 100mg, followed by monotherapy with dapsone 5% gel in improving and maintaining response in patients with moderate to severe acne. In this open-label study, all patients applied dapsone 5% gel twice daily along with doxycycline hyclate 100mg once daily for 12 weeks. Subjects who achieved a qualifying improvement at week 12 continued to the second phase of the study in which they applied only dapsone 5% gel twice daily for maintenance therapy of 12 more weeks. Subjects were evaluated for safety and efficacy at weeks 4, 8, 12, 16, 20, and 24. All subjects (n=30) in the initial phase qualified to enter the maintenance phase. 82% of participants maintained their treatment response (Investigator's Global Assessment score) at week 24. The regimen was safe and well tolerated. The combination oral doxycycline hyclate 100 mg with topical dapsone 5% gel twice daily is an effective and well-tolerated regimen to treat moderate to severe acne vulgaris. After discontinuation of doxycycline, topical dapsone 5% gel is effective at maintaining a therapeutic response. These data suggest that topical dapsone 5% gel can be used effectively for long-term acne maintenance treatment without the risk of developing antibiotic resistance.

    The face is the most exposed part of our body, and deterioration of facial appearance, through disease or ageing, causes psychological distress. Acne lesions and subsequent pigmentation changes contribute to the unevenness of skin colour that is detrimental to facial attractiveness and leads to rejection and stigmatization in our society. The purpose of this review is to look at the root causes of premenstrual acne and, for the first time ever, propose that the specific timing of treatment can, at least in part, resolve the acne lesions. We postulate that it is the timing of the manual extraction that matters in resolving premenstrual acne and that the effectiveness of this therapy could be improved. Based on the reviewed evidence, we propose that it is important to remove the comedones at the time of ovulation, prior to the reduction of the size of the sebaceous orifice and epidermal barrier function, to counteract the onset of increased sebum production, prevent blockage of the pores and subsequent bacterial colonization and inflammation. If performed successfully, the extraction may contribute to a reduction in inflamed acne lesions and thus benefit women by increasing their facial attractiveness, well-being, social function and thereby decrease psychological stress. © 2010 The Author.

    2016-12-01

    Guidelines recommend limiting the duration of oral antibiotic therapy in acne to 3 to 6 months and prescribing concomitant topical retinoids for all patients. We sought to evaluate the duration of therapy with oral tetracyclines and the use of topical retinoids among patients with acne treated primarily by general practitioners in the United Kingdom. We conducted a retrospective cohort study using the Health Improvement Network database. The mean duration of therapy was 175.1 days. Of antibiotic courses, 62% were not associated with a topical retinoid; 29% exceeded 6 months in duration. If all regions were to achieve uses similar to the region with the shortest mean duration of therapy, approximately 3.3 million antibiotic days per year could be avoided in the United Kingdom. The Health Improvement Network does not include information on acne severity and clinical outcomes. Prescribing behavior for oral antibiotics in the treatment of acne among general practitioners is not aligned with current guideline recommendations. Increasing the use of topical retinoids and considering alternative agents to oral antibiotics when appropriate represent opportunities to reduce antibiotic exposure and associated complications such as antibiotic resistance and to improve outcomes in patients treated for acne.

    The strong bactericidal properties of lauric acid (C12:0), a middle chain-free fatty acid commonly found in natural products, have been shown in a number of studies. However, it has not been demonstrated whether lauric acid can be used for acne treatment as a natural antibiotic against Propionibacterium acnes (P. acnes), which promotes follicular inflammation (inflammatory acne). This study evaluated the antimicrobial property of lauric acid against P. acnes both in vitro and in vivo. Incubation of the skin bacteria P. acnes, Staphylococcus aureus (S. aureus), and Staphylococcus epidermidis (S. epidermidis) with lauric acid yielded minimal inhibitory concentration (MIC) values against the bacterial growth over 15 times lower than those of benzoyl peroxide (BPO). The lower MIC values of lauric acid indicate stronger antimicrobial properties than that of BPO. The detected values of half maximal effective concentration (EC(50)) of lauric acid on P. acnes, S. aureus, and S. epidermidis growth indicate that P. acnes is the most sensitive to lauric acid among these bacteria. In addition, lauric acid did not induce cytotoxicity to human sebocytes. Notably, both intradermal injection and epicutaneous application of lauric acid effectively decreased the number of P. acnes colonized with mouse ears, thereby relieving P. acnes-induced ear swelling and granulomatous inflammation. The obtained data highlight the potential of using lauric acid as an alternative treatment for antibiotic therapy of acne vulgaris.

    Acne vulgaris is a prevalent skin disorder impairing both physical and psychosocial health. This study was designed to investigate the effectiveness of photodynamic therapy (PDT) combined with minocycline in moderate to severe facial acne and influence on quality of life (QOL). Ninety-five patients with moderate to severe facial acne (Investigator Global Assessment [IGA] score 3-4) were randomly treated with PDT and minocycline (n = 48) or minocycline alone (n = 47). All patients took minocycline hydrochloride 100 mg/d for 4 weeks, whereas patients in the minocycline plus PDT group also received 4 times PDT treatment 1 week apart. IGA score, lesion counts, Dermatology Life Quality Index (DLQI), and safety evaluation were performed before treatment and at 2, 4, 6, and 8 weeks after enrolment. There were no statistically significant differences in characteristics between 2 treatment groups at baseline. Minocycline plus PDT treatment led to a greater mean percentage reduction from baseline in lesion counts versus minocycline alone at 8 weeks for both inflammatory (-74.4% vs -53.3%; P acne patients.

    In westernized societies, acne vulgaris is a nearly universal skin disease afflicting 79% to 95% of the adolescent population. In men and women older than 25 years, 40% to 54% have some degree of facial acne, and clinical facial acne persists into middle age in 12% of women and 3% of men. Epidemiological evidence suggests that acne incidence rates are considerably lower in nonwesternized societies. Herein we report the prevalence of acne in 2 nonwesternized populations: the Kitavan Islanders of Papua New Guinea and the Aché hunter-gatherers of Paraguay. Additionally, we analyze how elements in nonwesternized environments may influence the development of acne. Of 1200 Kitavan subjects examined (including 300 aged 15-25 years), no case of acne (grade 1 with multiple comedones or grades 2-4) was observed. Of 115 Aché subjects examined (including 15 aged 15-25 years) over 843 days, no case of active acne (grades 1-4) was observed. The astonishing difference in acne incidence rates between nonwesternized and fully modernized societies cannot be solely attributed to genetic differences among populations but likely results from differing environmental factors. Identification of these factors may be useful in the treatment of acne in Western populations.

    Acne is one of the dermatological pathologies with the highest incidence around the world. It is a multifactorial disease and its treatment can be complex. Propionibacterium acnes play a key role in the inflammation of this dermatosis. Topical antibiotics, including mainly erythromycin and clindamycin, have been used, but there is controversy over their use due to the widely documented bacterial resistance. For this reason a meta-analysis of the publications over the past 10 years is presented in order to confirm this hypothesis. A search was made of the publications over the past 10 years that included the results of antibiogams of patients with acne. MeSH type searches were performed with the terms "acne vulgaris", "Propionibacterium acnes", "topical administration", "treatment", "erythromycin", "clindamycin", "nadifloxacin", "antibacterial agent", "bacterial drug resistance" in PubMed, Ovid, EBSCO, Cochrane, ScienceDirect and ClinicalKey meta-searches. A total of 13 articles were found that met the inclusion criteria. The mean odds ratio (OR 1.24, 95% CI) of the articles showed a slight tendency toward resistance of Propionibacterium acnes. An increase in bacterial resistance to topical erythromycin and clindamycin can be confirmed, thus the use of these antibiotics is recommended in selective cases for short periods, and in combination with benzoyl peroxide for the best clinical outcome in patients with acne vulgaris.

    Full Text Available STUDY BACKGROUND Post acne scars are always a challenge to treat, especially the ones which are deep seated. There are many treatment options like laser resurfacing, dermabrasion, microdermabrasion and non-ablative laser resurfacing but with considerable morbidity and interference with the daily activities of the patient in the post-treatment period. Microneedling or dermaroller therapy is one of the new treatment options in the management of acne scars with satisfactory improvement and no significant side effect. The aim of the present study is to perform an objective evaluation the efficacy of microneedling in the treatment of atrophic acne scars. MATERIALS AND METHODS Thirty patients of skin type III-V having atrophic facial acne scars presenting to our dermatology OPD. were received multiple sittings of microneedling (dermaroller treatment with an interval of 6 weeks between each session. Goodman & Baron’s acne scar grading system was used for assessment of their scars and was evaluated clinically by serial photography at the start as well as at two months after the conclusion of the treatment. Patients on anticoagulant therapy, of keloidal tendency, with bleeding disorders, vitiligo patients, pregnant and lactating mothers and patients with active acne lesions were excluded from the study. The duration of this study was for ten months-from January 2014 to October 2014. RESULTS Any change in the grading of scars after the end of treatment and follow-up period was noted down. The efficacy and improvement of dermaroller treatment was assessed by Goodman and Baron’s Global Acne Scarring System. Out of 30 patients, 26(80.64% patients achieved a reduction in the severity of their scarring by one or two grades. Quantitative assessment showed that 13.3% of patients had minimal, 16.6% had good and 70% showed very good improvement. Adverse effects were limited to transient pain, erythema and edema. CONCLUSION Microneedling therapy seems to be

    Acne vulgaris is a chronic skin disease with a high prevalence. Left untreated or inadequately treated, acne vulgaris can lead to psychological and physical scarring, as well as to unnecessary medical expenses. Oral isotretinoin is an effective treatment for severe resistant nodular and conglobate acne vulgaris. A regimen consisting of a fixed-dose combination of adapalene and benzoyl peroxide gel, 0.1%/2.5% (A-BPO) with oral doxycycline 100 mg (A-BPO/D) has been demonstrated to be efficacious and well tolerated in patients with severe acne and may be an alternative to oral isotretinoin for some patients with severe acne. The objective of this analysis was to compare the relative efficacy and associated costs of A-BPO/D versus oral isotretinoin. In this analysis, comparisons of relative efficacy were made using previously published studies involving similar patient populations with severe acne that warrant the use of oral isotretinoin. The pricing for oral doxycycline and oral isotretinoin was estimated based on the maximum allowable cost from 9 states, and the pricing for A-BPO was calculated as the range between the average wholesale price and the wholesale acquisition cost. For this analysis, 2 treatment models were generated to compare costs: (1) a basic treatment model that examined the costs of an initial regimen of either A-BPO/D or oral isotretinoin without considering probable outcomes, and (2) a long-term model that factored in likely treatment outcomes and subsequent treatments into associated costs. The basic treatment model assumed that patients would be prescribed a single regimen of A-BPO/D for 12 weeks or oral isotretinoin for 20 weeks. The long-term model considered the probability of each treatment successfully managing patients' acne, as well as likely additional regimens of A-BPO monotherapy or an additional regimen of oral isotretinoin. As a result of different treatment durations, the costs for each treatment were normalized to weekly cost of

  9. Dietary intervention in acne

    The purpose of this paper is to highlight the endocrine signaling of Western diet, a fundamental environmental factor involved in the pathogenesis of epidemic acne. Western nutrition is characterized by high calorie uptake, high glycemic load, high fat and meat intake, as well as increased consumption of insulin- and IGF-1-level elevating dairy proteins. Metabolic signals of Western diet are sensed by the nutrient-sensitive kinase, mammalian target of rapamycin complex 1 (mTORC1), which integrates signals of cellular energy, growth factors (insulin, IGF-1) and protein-derived signals, predominantly leucine, provided in high amounts by milk proteins and meat. mTORC1 activates SREBP, the master transcription factor of lipogenesis. Leucine stimulates mTORC1-SREBP signaling and leucine is directly converted by sebocytes into fatty acids and sterols for sebaceous lipid synthesis. Over-activated mTORC1 increases androgen hormone secretion and most likely amplifies androgen-driven mTORC1 signaling of sebaceous follicles. Testosterone directly activates mTORC1. Future research should investigate the effects of isotretinoin on sebocyte mTORC1 activity. It is conceivable that isotretinoin may downregulate mTORC1 in sebocytes by upregulation of nuclear levels of FoxO1. The role of Western diet in acne can only be fully appreciated when all stimulatory inputs for maximal mTORC1 activation, i.e., glucose, insulin, IGF-1 and leucine, are adequately considered. Epidemic acne has to be recognized as an mTORC1-driven disease of civilization like obesity, type 2 diabetes, cancer and neurodegenerative diseases. These new insights into Western diet-mediated mTORC1-hyperactivity provide a rational basis for dietary intervention in acne by attenuating mTORC1 signaling by reducing (1) total energy intake, (2) hyperglycemic carbohydrates, (3) insulinotropic dairy proteins and (4) leucine-rich meat and dairy proteins. The necessary dietary changes are opposed to the evolution of

    Benzoyl peroxide was introduced as a basic treatment already in acne therapy 1934. The mechanism of action is the reduction of anaerobe bacteria by strong oxidation processes. No resistancies have been ever reported. BPO is available in 2.5, 5 and 10 % formulations. Its efficacy is slightly related to the strength of concentrations, but the side effect profile with burning, erythema and desquamation is increasing with concentrations. BPO 5% mostly is efficient enough to control acne of grades I to II according to the Kligman & Plewig classification. BPO my bleach clothes and hair. It is the most costeffective topical drug in acne of grades I-II. Inflammatory acne of the papular-pustular type I-II can also be treated by topical antibiotics such as erythromycin, clindamycin, and, less frequent and today not anymore recommended tetracyclines. Mechanism of action is not alone an antibacterial but anti inflammatory effect. The efficacy and penetration of the topical antibiotics between the groups are similar. Randomized studies have shown that concentrations of 2-4% are equivalent to oral tetracycline and minocycline in mild to moderate acne. Combinatory formulations with BPO and with retinoids enhance the efficacy significantly. Topical antibiotics plus BPO show less bacterial resistancies as topical antibiotics alone. Antibiotics should therefore not be used as monotherapy. Moreover gram negative folliculitis may develop. Azelaic acid is acting as an antimicrobial and can also reduce comedones. It can also be used in pregnancy and during the lactation period.

    Propionibacterium acnes is a Gram-positive bacterium that is intimately associated with humans. The nature and consequences of this symbiosis are poorly understood; it might comprise both mutualistic and parasitic properties. Recent advances in distinguishing phylotypes of P. acnes have revealed...... that certain type I lineages are predominantly associated with acne vulgaris. Genome analyses revealed a highly conserved core genome and the existence of island-like genomic regions and possible mobile genetic elements as part of the flexible gene pool. The analysis of clustered regularly interspaced short...... palindromic repeats (CRISPR), found exclusively in type II P. acnes, recently revealed the presence of CRISPR spacers that derived from mobile genetic elements. These elements are present in a subset of P. acnes type I lineages. Their significance for type-specific host-interacting properties...

    The effects of chocolate on acne exacerbations have recently been reevaluated. For so many years, it was thought that it had no role in worsening acne. To investigate whether 99% dark chocolate, when consumed in regular daily amounts, would cause acne to worsen in acne-prone male subjects, twenty-five acne prone male subjects were asked to consume 25 g of 99% dark chocolate daily for 4 weeks. Assessments which included Leeds revised acne scores as well as lesion counts took place weekly. Food frequency questionnaire was used, and daily activities were recorded. Statistically significant changes of acne scores and numbers of comedones and inflammatory papules were detected as early as 2 weeks into the study. At 4 weeks, the changes remained statistically significant compared to baseline. Dark chocolate when consumed in normal amounts for 4 weeks can exacerbate acne in male subjects with acne-prone skin. © 2015 The International Society of Dermatology.

    In this project, hydrogel patches containing herbal extracts mixture were developed by radiation technology for acne treatment. Propionibacterium acnes (P. acnes), one of the anaerobic bacterium, is the cause of inflammatory acne. To find novel mediation for inflammation of P. acnes, we confirmed the anti-bacterial and anti-inflammatory activities of several herbal extracts against P. acnes. The water extracts from five dried herbs, Phellodendron amurense Rupr., Paeonia lactiflora Pallas., Houttuynia cordata Thumb., Agrimonia pilosa Ledeb. and Glycyrrhiza uralensis Fisch., were mixed into biocompatible polymers and irradiated by using gamma-ray to prepare hydrogels. The hydrogels containing herbal extracts mixture initiated to decrease the growth of P. acnes and reduced the production of pro-inflammatory cytokines, TNF-α, IL-8, IL-1β and IL-6, in experiment with human monocytic THP-1 cells treated with heat-killed P. acnes at 1 mg/ml of mixture concentration

    To some degree, acne vulgaris affects nearly every individual worldwide. Oral antibiotic therapy is routinely prescribed for the treatment of moderate to severe inflammatory acne; however, long-term use of oral antibiotics for acne may have unintended consequences. The aim of this study was to provide a systematic evaluation of the scientific evidence on the efficacy and appropriate use of oral antibiotics in the treatment of acne. A systematic search of MEDLINE was conducted to identify randomized controlled clinical trials, systematic reviews, and meta-analyses evaluating the efficacy of oral antibiotics for acne. Overall, 41 articles that examined oral antibiotics compared with placebo, another oral therapy, topical therapy, alternate dose, or duration were included in this study. Tetracyclines, macrolides, and trimethoprim/sulfamethoxazole are effective and safe in the treatment of moderate to severe inflammatory acne. Superior efficacy of one type or class of antibiotic could not be determined, therefore the choice of antibiotic is generally based on the side-effect profile. Although different dosing regimens have been studied, there is a lack of standardized comparator trials to determine optimal dosing and duration of each oral antibiotic used in acne. The combination of oral antibiotics with a topical therapy is superior to oral antibiotics alone. This article provides a systematic evaluation of the scientific evidence of the efficacy of oral antibiotics for acne. Due to heterogeneity in the design of the trials, there is insufficient evidence to support one type, dose, or duration of oral antibiotic over another in terms of efficacy; however, due to increasing resistance to antibiotics, dermatologists should heed consensus guidelines for their appropriate use.

    The standard management of acne vulgaris in Japan includes a combination of topical treatment with benzoyl peroxide (BPO) and BPO/clindamycin (CLDM), topical adapalene and systemic antimicrobials. However, the treatment of therapy-resistant complications such as postinflammatory hyperpigmentation (PIH), erosions with inflamed red papules and atrophic scars has not been established. We performed chemical peeling with glycolic acid and iontophoresis with ascorbyl 2-phosphate 6-palmitate and DL-α-tocopherol phosphate for the treatment of PIH, erosions with inflamed red papules and non-inflamed atrophic scars in 31 patients with acne vulgaris (mild to severe severity), and evaluated the efficacy and safety of these interventions. In most of cases, there was remarkable improvement in PIH and erosions with inflamed red papules after treatment. There was also some improvement in non-inflamed atrophic scars without erythema. Mild redness and irritation was observed in four cases as adverse reactions. Early initial treatment of PIH and erosions with red papules by chemical peeling and iontophoresis is an effective and safe method to prevent the formation of atrophic scars in patients with acne vulgaris. © 2016 Japanese Dermatological Association.

    2016-12-01

    Full Text Available Polyphenols are antioxidant molecules found in many foods including nuts, fruits, vegetables, chocolate, wine, and tea. Polyphenols have antimicrobial, anti-inflammatory, and antineoplastic properties. Recent studies suggest that tea polyphenols may be used for reducing sebum production in the skin and for treatment of acne vulgaris. This review examines the evidence for use of topically and orally ingested tea polyphenols against sebum production and for acne treatment and prevention. The PubMed database was searched for studies on tea polyphenols, sebum secretion, and acne vulgaris. Of the 59 studies found, eight met the inclusion criteria. Two studies evaluated tea polyphenol effects on sebum production; six studies examined tea polyphenol effects on acne vulgaris. Seven studies evaluated topical tea polyphenols; one study examined systemic tea polyphenols. None of the studies evaluated both topical and systemic tea polyphenols. Tea polyphenol sources included green tea (six studies and tea, type not specified (two studies. Overall, there is some evidence that tea polyphenols in topical formulation may be beneficial in reducing sebum secretion and in treatment of acne. Research studies of high quality and with large sample sizes are needed to assess the efficacy of tea polyphenols in topical and oral prevention of acne vulgaris and lipid synthesis by the sebaceous glands.

  2. The effect of a daily facial cleanser for normal to oily skin on the skin barrier of subjects with acne.

    Acne vulgaris is a common skin disorder that affects many people every year, especially the teenaged population. People with acne find the condition especially difficult to manage because of the disease's chronicity and variability in response to treatment. Acne is the result of pores clogged with shed skin cells combined with sebum in the hair follicle. Successful treatment of acne is important because acne has the potential to result in lasting physical and emotional scarring. For many years, physicians have agreed that although cleansing is not effective on its own, effective cleansing is an important part of any acne treatment regimen. However, patients have not been satisfied with the types of cleansers available. In addition to containing dyes and perfumes that can irritate and exacerbate acne, these cleansers often are too harsh and can result in excessive drying of the skin, which leads to overcompensation by the oil glands and ultimately to more oil on the surface of the skin. This study examined the use of a daily facial cleanser formulated for normal to oily skin in subjects with mild facial acne. The cleanser was studied for 2 weeks in the absence of additional treatments to eliminate the confounding effects of various treatments. Subjects were monitored for skin barrier function through transepidermal water loss (TEWL) and corneometry, sebum level, and lesion counts. The results of the study indicate that the facial cleanser is gentle and does not damage the skin barrier or result in sebum overcompensation; additionally, the cleanser is effective at deep-pore cleansing, which may help to manage some acne-associated symptoms.

    Full Text Available Background: Acne is the most common disorder treated by dermatologists. As many as 80-90% of all adolescents have some type of acne and 30% of them require medical treatment. It is an inflammatory disease of the pilosebaceous unit characterized by the formation of open and closed comedones, papules, pustules, nodules, and cysts. Aims: The present study was conducted to investigate the in vitro anti-acne activity of two Unani single drugs Darchini (Cinnamomum zeylanicum Bl. and Tukhm Khashkhash (Papaver somniferum L. seeds. Materials and Methods: The antibacterial activity of aqueous, ethanolic and hydroalcoholic extracts of both drugs were investigated against two acne causing bacteria, i.e., Propionibacterium acne and Staphylococcus epidermidis using well diffusion method. Results: The result showed that both drugs were active against the two bacteria. Against P. acne aqueous and ethanolic extract of Darchini and Tukhm Khashkhash showed the zone of inhibition of 18 ± 1.02 mm and 18 ± 1.6 mm and 13 ± 1.04 mm and 14 ± 1.8 mm, respectively. Against S. epidermidis aqueous, hydroalcoholic and ethanolic extracts of Darchini showed 22 ± 1.7 mm, 22 ± 1.2 mm and 15 ± 1.8 mm zone of inhibition respectively. Hydroalcoholic and ethanolic extracts of Tukhm Khashkhash showed 15 ± 1.09 mm and 13 ± 1.6 mm zone of inhibition respectively. Conclusion: This suggests that C. zeylanicum and P. somniferum have potential against acne causing bacteria and hence they can be used in topical anti-acne preparations and may address the antibiotic resistance of the bacteria.

    Postadolescent acne is usually described as an inflammatory, mild-to-moderate dermatosis, frequently involving the lower third of the face, the jawline, and the neck. However, we have also frequently observed a clinical form predominantly characterized by retention lesions (microcomedones and macrocomedones), with few inflammatory lesions (comedonal postadolescent acne [CPAA]), which appears significantly correlated with cigarette smoking. We sought to investigate the clinical features of postadolescent acne in a group of female patients affected by acne and its relationship with cigarette smoking. A total of 226 women with acne (25-50 years) attending our department were examined by a team of 3 dermatologists, to assess the age of onset of the disease, and the number, type, and distribution of acne lesions. In all, 192 of 226 patients (85.0%) were classified as having CPAA and 34 as having papulopustular postadolescent acne. A smoking habit was confirmed in 150 of 226 (66.3%). Remarkably, 72.9% of patients with CPAA were smokers as compared with only 29.4% of those with papulopustular postadolescent acne (P < .0001). Possible limitations are related to geographic area or to the prevalence of darker skin types (III and IV) (data about skin types have not been collected). Other possible aggravating factors (ie, stress and diet) have not been investigated. According to our results, CPAA appears as the most frequent clinical form of postadolescent acne and seems to be strictly correlated with cigarette smoking.

    The basic properties of lasers and pulsed light sources limit their ability to deliver high energy to the dermis and subcutaneous tissues without excessive damage to the epidermis. Radiofrequency was shown to penetrate deeper than optical light sources independent of skin color. The early RF-based devices used single source bipolar RF, which is safe but limited in use due to the superficial flow of energy between the two bipolar electrodes. Another type of single source RF employs a single electrode (monopolar) in which the RF energy flows from one electrode on the surface of the skin through the entire body to a plate under the body. Although more effective than bipolar, this devices require intense active cooling of the skin and may be associated with considerable pain and other systemic and local safety concerns. Latest generation of RF technology developed by EndyMed Medical Ltd. (Caesarea, Israel) utilizes simultaneously six or more phase controlled RF generators (3DEEP technology). The multiple electrical fields created by the multiple sources “repel” or “attract” each other, leading to the precise 3 dimensional delivery of RF energy to the dermal and sub-dermal targets minimizing the energy flow through the epidermis without the need for active cooling. Confocal microscopy of the skin has shown that 6 treatment sessions of Multisource RF technology improve skin structure features. The skin after treatment had longer and narrower dermal papilla and denser and finer collagen fiber typical to younger skin as compared to pre treatment skin. Ultrasound of the skin showed after 6 treatment sessions reduction of 10 percent in the thickness of the subcutaneous fat layer. Non ablative facial clinical studies showed a significant reduction of wrinkles after treatment further reduced at 3 months follow-up. Body treatment studies showed a circumference reduction of 2.9 cm immediately after 6 treatments, and 2 cm at 12 months after the end of treatment, proving

    In contrast to adolescent acne, infantile acne (IA) is a rare condition with only a limited body of available literature. In this descriptive, retrospective study, we reviewed six cases from 2002 to 2010 treated with oral isotretinoin. The average age of onset was 6.16 months (range 0-21 mos......). Consistent with the previous, limited literature, we found predominantly boys are affected, a predilection for the cheeks, and a polymorphic inflammatory morphology. Two patients had a family history of acne. All cases were successfully and safely treated with oral isotretinoin. The suggested treatment...... of childhood acne is similar to that of adolescents (graded according to the severity of the skin disease and risk of scarring). Oral isotretinoin appears to be an effective and safe treatment for severe IA....

    Acne is a common skin condition present predominantly in the adolescent population, but may continue into adulthood. Scarring occurs commonly as a sequel to severe inflammatory acne. The presence of acne and resultant scars are more than cosmetic, with a significant potential to alter quality of life and even job prospects. The psychosocial effects of acne and scars can be disturbing and may be a risk factor for serious psychological concerns. Treatment efficacy is generally determined based on an invalidated gestalt by the physician and patient. However, the validated assessment of acne can be challenging and time consuming. Acne can be classified into several morphologies including closed comedones (whiteheads), open comedones (blackheads), papules, pustules, cysts (nodules) and scars. For a validated assessment, the different morphologies need to be counted independently, a method that is far too time consuming considering the limited time available for a consultation. However, it is practical to record and analyze images since dermatologists can validate the severity of acne within seconds after uploading an image. This paper covers the processes of region-ofinterest determination using entropy-based filtering and thresholding as well acne lesion feature extraction. Feature extraction methods using discrete wavelet frames and gray-level co-occurence matrix were presented and their effectiveness in separating the six major acne lesion classes were discussed. Several classifiers were used to test the extracted features. Correct classification accuracy as high as 85.5% was achieved using the binary classification tree with fourteen principle components used as descriptors. Further studies are underway to further improve the algorithm performance and validate it on a larger database.

    Full Text Available Introduction: Acne scars are the result of inflammation within the dermis brought on by acne. The scar is created by the wound trying to heal itself resulting in too much collagen in one spot. Current treatment available are not much satisfactory. Microneedling injure the dermis, thereby stimulating collagen formation. Glycolic acid acts as vehicle for delivery of drugs to dermis: in addition to that, it also has a role in collagen induction. Tretinoin helps in collagen formation. Salicylic acid remodel the superficial skin after the treatment. Material and Methods: A total of 4 patients in which 3 out of 4 patient, grade 3 acne scars and 1 out of 4 had grade 2 scar were treated with the regime. After taking consent 35% Glycolic acid peeling was done followed by microneedling. From the next day 12% Glycolic acid plus 0.05% Tretinoin is applied once a day for 2 months. After 2 months 30% Salicylic acid peeling is done. Photographs were taken before treatment, after 1 month and after 2 months of completion of the therapy and compared. Objective assessment was done according to Global Acne Scarring Classification. Result: subjectively 2 patients reported excellent response and 2 patients reported good response. Objectively, all patients showed good to excellent response. Conclusion: Zonun’s regime may be effective for treatment of acne scars.

    The purpose of this study was to assess the sonographic morphology of the clinical and subclinical pathology of facial acne vulgaris. We studied patients with facial acne vulgaris diagnosed by certified dermatologists, and using a standardized protocol for sonographic examinations, we sequentially described the sonographic pathomorphologic characteristics. Lesions of particular interest to the referring clinician were also analyzed separately. Additionally, acne involvement was staged clinically and sonographically (SOS-Acne) using morphologic definitions of the relevant lesions and predefined scoring systems for gradation of the severity of acne lesions. A total of 245 acne lesions in 20 consecutive patients were studied. Sonographic abnormalities consisted of pseudocysts, folliculitis, fistulas, and calcinosis. Most conditions were subclinical and mostly due to lesion extensions deep into the dermis and hypodermis (52% of pseudocysts and 68% of fistulas). The statistical concordance between acne severity scores assigned by two separate clinicians was strong (κ = 0.8020), but the corresponding sonographic scores generally showed more severe and clinically occult involvement. Facial acne vulgaris often involves deeper tissues, beyond the reach of the spatially restricted clinical examination; these subclinical conditions can be detected and defined with sonography. Additionally, acne vulgaris is amenable to sonographic scoring.

    Growing numbers of post-adolescent females are suffering from treatment-resistant or relapsing adult acne forms, therefore requiring the definition of safe and effective treatment options for this burdening disease. To assess the efficacy of azelaic acid 15% gel (AzA) vs. no treatment during maintenance therapy of female adult acne and to compare its efficacy and safety vs. adapalene 0.1% gel (AD) during a 9-month period (3-month treatment and 6-month maintenance treatment). A total of 55 women between 18 and 45 years with adult acne were included in this investigator-blind trial and randomized into three groups receiving AzA gel b.i.d. for 9 months (AzA9M, n = 17) or AzA gel b.i.d. for 3 months followed by a 6-month observational phase (AzA3M, n = 19) or AD gel once daily for 9 months (AD9M, n = 19). Parameters of efficacy, safety and patient-related factors were analysed. The reduction in lesion counts, severity and Dermatology Life Quality Index score was significant (P < 0.05) and comparable between groups during the treatment phase, while dryness and scaling were significantly lower (P < 0.05) in group AzA9M vs. AD9M. During maintenance, AzA9M was superior to AzA3M in the control of inflammatory lesions (P = 0.008) and total lesions (P = 0.014) at week 24. From week 12 to week 36, a mild relative increase in inflammatory lesions could be observed in all groups. In AzA3M, this increase exceeded that of AzA9M by 23.1% (P = 0.109), while the difference of total lesions diverged to 30.8% (P = 0.038). No significant differences could be detected between AzA9M and AD9M. Group AzA9M was non-inferior to AD9M (non-inferiority margin of 50% for the confidence limit for the relative effect) in the control of inflammatory acne lesions. AzA15% gel is a safe and effective treatment and maintenance treatment of female adult acne with non-inferior efficacy to AD 0.1% gel in the control of inflammatory acne. © 2014 European Academy of Dermatology and Venereology.

    Treatment of acne vulgaris (acne) with dapsone gel, 5% requires twice-daily dosing, and some patients may not adhere to this regimen. The objective of this study was to assess the efficacy and safety of a new, once-daily formulation of dapsone gel, 7.5%, with a 50% higher dapsone concentration, versus vehicle over 12 weeks in patients with acne. This 12-week, randomized, double-blind, vehicle-controlled, multicenter clinical trial enrolled patients with moderate acne aged 12 years and older with 20 to 50 inflammatory lesions and 30 to 100 noninflammatory lesions on the face, and an acne grade of 3 (moderate) on the Global Acne Assessment Score (GAAS). Patients were randomized to receive topical dapsone gel, 7.5% or vehicle once daily for 12 weeks. Investigators assessed GAAS success rate (proportion of patients with GAAS of 0 or 1) and percent change from baseline in inflammatory, noninflammatory, and total lesions. The intent-to-treat population comprised 2102 patients, 1044 in the dapsone gel, 7.5% group and 1058 in the vehicle group. At week 12, 29.9% of patients in the dapsone gel, 7.5% group and 21.2% in the vehicle group (Pdapsone gel, 7.5% and vehicle groups (all Pdapsone gel, 7.5% (19.1%) and vehicle (20.6%) groups. Most events in both groups were mild or moderate in severity. Most patients receiving dapsone gel, 7.5% and vehicle had a severity rating of "none" for stinging/burning, dryness, scaling, and erythema scales at all time points. Dapsone gel, 7.5% applied topically once daily is an effective, safe, and well-tolerated treatment for acne. J Drugs Dermatol. 2016;15(5):553-561.

    The anaerobic gram-positive bacterium Propionibacterium acnes is a human skin commensal that is occasionally associated with inflammatory diseases. Recent work has indicated that evolutionary distinct lineages of P. acnes play etiologic roles in disease while others are associated with maintenance of skin homeostasis. To shed light on the molecular basis for differential strain properties, we carried out genomic and transcriptomic analysis of distinct P. acnes strains. We sequenced the genome of the P. acnes strain 266, a type I-1a strain. Comparative genome analysis of strain 266 and four other P. acnes strains revealed that overall genome plasticity is relatively low; however, a number of island-like genomic regions, encoding a variety of putative virulence-associated and fitness traits differ between phylotypes, as judged from PCR analysis of a collection of P. acnes strains. Comparative transcriptome analysis of strains KPA171202 (type I-2) and 266 during exponential growth revealed inter-strain differences in gene expression of transport systems and metabolic pathways. In addition, transcript levels of genes encoding possible virulence factors such as dermatan-sulphate adhesin, polyunsaturated fatty acid isomerase, iron acquisition protein HtaA and lipase GehA were upregulated in strain 266. We investigated differential gene expression during exponential and stationary growth phases. Genes encoding components of the energy-conserving respiratory chain as well as secreted and virulence-associated factors were transcribed during the exponential phase, while the stationary growth phase was characterized by upregulation of genes involved in stress responses and amino acid metabolism. Our data highlight the genomic basis for strain diversity and identify, for the first time, the actively transcribed part of the genome, underlining the important role growth status plays in the inflammation-inducing activity of P. acnes.

    To investigate the effects of different doses of isotretinoin on serum homocysteine, vitamin B12 and folic acid in patients with acne vulgaris. The case-control study was conducted at Gazi University School of Medicine, Ankara, Turkey, from November 2012 to March 2013, and comprised male or non-pregnant female patients more than 18 years of age. The cases had moderate to severe nodulocystic acne, while an equal and matching control group had healthy individuals. Isotretinoin was started in a dosage of 0.5 mg/kg/day, and 1.0 mg/kg/day in patients with medium and severe acne vulgaris respectively. Homocysteine, vitamin B12, folic acid, liver function tests, serum cholesterol and triglyceride levels were tested at the baseline and on day 45. SPSS 11 was used for statistical analysis. The two groups had 62 subjects each. The cases had 47(76%) women and 15(25%) men with a group mean age of 21.0±2.7 years. The controls had 45(72.6%) women and 17(27.4%) men with a group mean age of 21.6±3.0 years. Homocysteine levels were significantly increased in both groups taking 0.5 mg/kg/day and 1.0 mg/kg/day isotretinoin (p0.05 each). Total cholesterol level increased significantly in the group using 1.0 mg/kg/day (p<0.05). In the triglyceride levels, significant increases were seen in both groups (p<0.05). Evaluation of homocysteine, vitamin B12 and folic acid beside the routine tests were beneficial for the patients before they started isotretinoin treatment.

    The common skin disease acne vulgaris is caused by Propionibacterium acnes. A lipase secreted by this microorganism metabolizes sebum and the resulting metabolites evoke inflammation in human skin. The antifungal drug ketoconazole inhibits P. acnes lipase activity. We previously showed that the drug also inhibits the growth of P. acnes. Thus, ketoconazole may serve as an alternative treatment for acne vulgaris, which is important because the number of antibiotic-resistant P. acnes strains has been increasing. © 2017 The Societies and John Wiley & Sons Australia, Ltd.

    Full Text Available BACKGROUND Acne vulgaris is a highly prevalent chronic inflammatory disease of pilosebaceous unit affecting teenagers and young adults. Prognosis of acne is generally good, especially in mild acne. But, this disease reduces the self-esteem, their sense of identity and can severely compromise quality of life. All clinicians caring for children and adolescents should be familiar with this problem. Early diagnosis, proper treatment and timely counselling reduce the overall impact of disease to individuals. MATERIALS AND METHODS This is a prospective study conducted in the Department of Dermatology at Government Medical College, Kottayam, Kerala, in 200 patients who presented to the outpatient clinic with a clinical diagnosis of acne vulgaris who have not yet received any medical treatment for the disease and consented to participate in the study. RESULTS Male-to-female ratio of 1.43:1. 61.5% patients were in the 2nd decade. 4% were more than 30 years old. Duration of the disease at the time of presentation ranged from 3 weeks to 30 years. 42.5% complained of mild itching and 18.5% had burning sensation. 48.5% attribute exacerbation of disease after food intake. 72.5% acne patients had seborrhoea. Hirsutism and Acanthosis nigricans were present in 7.31% and 4.87% female patients, respectively. 50% with hirsutism and 25% with Acanthosis nigricans had polycystic ovarian disease and severe grades of acne. 25.6% females complained of premenstrual exacerbation of the disease. 26% of the patients showed exacerbation in summer. Smokers had severe grades of acne vulgaris compared to nonsmokers. Comedones were present in all and they were the predominant lesions in majority. Inflammatory papules were the 2nd most common lesions. Severe grades of acne were more common in patients with age ≥20 years. Severity of the disease increases with long duration of the disease. Relatively high incidence of post-acne scarring and post-inflammatory hyperpigmentation was

    Adolescent acne impacts self-esteem and quality of life in adolescents and its aetiology is not fully clarified. The aim of this study was to describe the epidemiological features of adolescent acne in North East China and determine the impact of genetic and environmental factors on the pathogenesis of acne. Data were collected from 5696 undergraduates (2920 patients and 2776 controls) using questionnaire. The survey data were analysed using spss version 13.0 and heritability of adolescent acne was calculated using Falconer's method. Total prevalence of adolescent acne was 51.30% (52.74% in males, 49.65% in females). The difference between genders was statistically significant (P skin and mixed type skin. Protective factors include (presented in descending order of occurrence) dry skin, neutral skin, frequent fruit consumption and computer access time skin oiliness and high caloric diets may also contribute to the onset of acne in Chinese adolescents.

    It is known that effectiveness of acne treatment increases when the lesions are detected earlier, before they could progress into mature wound-like lesions, which lead to scarring and discoloration. However, little is known about the evolution of acne from early signs until after the lesion heals. In this work we computationally characterize the evolution of inflammatory acne lesions, based on analyzing cross-polarized images that document acne-prone facial skin over time. Taking skin images over time, and being able to follow skin features in these images present serious challenges, due to change in the appearance of skin, difficulty in repositioning the subject, involuntary movement such as breathing. A computational technique for automatic detection of lesions by separating the background normal skin from the acne lesions, based on fitting Gaussian distributions to the intensity histograms, is presented. In order to track and quantify the evolution of lesions, in terms of the degree of progress or regress, we designed a study to capture facial skin images from an acne-prone young individual, followed over the course of 3 different time points. Based on the behavior of the lesions between two consecutive time points, the automatically detected lesions are classified in four categories: new lesions, resolved lesions (i.e. lesions that disappear completely), lesions that are progressing, and lesions that are regressing (i.e. lesions in the process of healing). The classification our methods achieve correlates well with visual inspection of a trained human grader.

    Background: Acne vulgaris is commonplace and can be difficult to manage. Providing an effective and well-tolerated treatment may lead to improved adherence, increased patient satisfaction, and improved clinical outcomes. Methods: A review of efficacy, safety, and cutaneous tolerability of clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel in 498 patients with moderate-to-severe acne vulgaris enrolled in a multicenter Phase III study randomized to receive active or vehicle once daily for 12 weeks, including the most recent post-hoc analyses. Results: Significantly superior reductions in lesion counts were observed with clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel from Week 4, with median percent reductions in inflammatory and noninflammatory lesions from baseline of 68.4 and 57.9 percent, respectively (bothpacne vulgaris patients treated with clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel achieved ≥2-grade improvement from baseline in their Evaluator’s Global Severity Score, and almost a third of the adolescent acne vulgaris patients (32.4%) achieved at least a marked improvement in their acne vulgaris as early as Week 2. In adult female acne overall treatments success was achieved in 52.7 percent of patients treated with clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel. Overall, and in the specific subpopulations, clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel was well-tolerated with a similar adverse event profile to vehicle. Limitations: Post-hoc analyses from a single clinical trial with demographic imbalances that could potentially confound the results. Conclusion: Clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel appears to be effective in treating acne across various clinically relevant sub-groups. PMID:26705445

    This study evaluated the antimicrobial activity of lauric acid (LA) and its liposomal derivatives against Propionibacterium acnes (P. acnes), the bacterium that promotes inflammatory acne. First, the antimicrobial study of three free fatty acids (lauric acid, palmitic acid and oleic acid) demonstrated that LA gives the strongest bactericidal activity against P. acnes. However, a setback of using LA as a potential treatment for inflammatory acne is its poor water solubility. Then the LA was incorporated into a liposome formulation to aid its delivery to P. acnes. It was demonstrated that the antimicrobial activity of LA was not only well maintained in its liposomal derivatives but also enhanced at low LA concentration. In addition, the antimicrobial activity of LA-loaded liposomes (LipoLA) mainly depended on the LA loading concentration per single liposomes. Further study found that the LipoLA could fuse with the membranes of P. acnes and release the carried LA directly into the bacterial membranes, thereby killing the bacteria effectively. Since LA is a natural compound that is the main acid in coconut oil and also resides in human breast milk and liposomes have been successfully and widely applied as a drug delivery vehicle in the clinic, the LipoLA developed in this work holds great potential of becoming an innate, safe and effective therapeutic medication for acne vulgaris and other P. acnes associated diseases.

    Acne is prevalent among adolescents and adults with significant psychological effects. Standard oral and topical therapies can have significant side effects including skin irritation, gastrointestinal upset, and the development of drug-resistant bacteria. The use of botanicals and phytochemicals in dermatological products is increasingly popular, and many patients are turning to these alternative therapies for treatment of acne. This study aimed to systematically review clinical studies that have investigated the use of botanical agents in the treatment of acne. PubMed and Embase databases were searched in March 2013 for trials assessing botanical therapies in the treatment of acne vulgaris. Data from these trials are presented, and methodology of each study is assessed. Twenty-three trials met inclusion criteria. Interventions included plant extracts, herbal formulations, and phytochemicals. All studies reported favorable results, and several showed equal or superior treatment to standard therapies. No serious adverse events were reported. Few studies were methodologically rigorous. Each botanical was studied in only one or two trials. Botanicals are promising therapies for acne vulgaris although further research is warranted, especially with regard to severe acne and acne resistant to conventional therapy.

    Full Text Available Acne is a manifestation of hormonal overstimulation of the pilosebaceous units of genetically susceptible individuals. Endogenous reproductive and growth hormones, exogenous reproductive hormones, insulin and endogenous insulin-like growth hormone-1, sourced from and stimulated by dairy and high glycemic load foods, all appear to contribute to this overstimulation. A postulated molecular mechanism linking food and acne is reported and integrated into the clinical picture.

    Acne agminata is an asymptomatic papulopustular eruption. This condition typically occurs in young adults. The eruption generally runs a self-limited course, but disfiguring scars can occur. Histological examination shows scattered dermal granulomas composed of epitheloid and some giant cells with central caseation. A variety of agents such as wide spectrum antibiotics, oral steroids, dapsone and clofazimine have been used with varying degrees of success. Herein, we report 2 Caucasian males with acne agminata successfully treated with isotretinoin. (author)

    Forbidden foods? "The first law of dietetics seems to be: If it tastes good, it's bad for you" (Isaac Asimov, Russian-born biochemist and science fiction writer). This was essentially the Magna Carta for dermatologists of the 1950s: anything coveted by the teenage palate was suspect for morning after acne. Today, half a century later, although the slant has shifted away for this line of thinking in our dermatologic textbooks, several articles on the beliefs and perceptions of acne patients showed that nothing much has changed and that they expect us to give them detailed instructions of what "acne-related" foods they should avoid. In one such study(1), diet was the third most frequently implicated factor (after hormones and genetics) as the cause of the disease, with 32% of the respondents selecting diet as the main cause, and 44% thinking that foods aggravate acne. In another study that analyzed knowledge about causes of acne among English teenagers, 11% of the responders blamed greasy food as the main cause of the disease(2), whereas in another study found that 41% of final-year medical students of the University of Melbourne chose diet as an important factor of acne exacerbation on a final examination.(3)

  15. Nanoparticle Stabilized Liposomes for Acne Therapy

    Science.gov (United States)

    Fu, Victoria

    Acne vulgaris is a common skin disease that affects over 40 million people in the United States alone. The main cause of acne vulgaris is Propionibacterium acnes (P. acnes), resides deep in the pores and follicles of the skin in order to feed on oil produced by the sebaceous glands. The liposome is a lipid based nanoparticle with numerous advantages over free drug molecules as an acne treatment alternative. Bare liposomes loaded with lauric acid (LipoLA) were found to show strong antimicrobial activity against P. acnes while generating minimal toxicity. However, the platform is limited by the spontaneous tendency of liposomes to fuse with each other. Attaching nanoparticles to the surface of liposomes can overcome this challenge by providing steric repulsion and reduce surface tension. Thus, carboxyl-functionalized gold nanoparticles (AuC) were attached to the surface of liposomes (AuC-liposomes) loaded with doxycycline, a general tetracycline antibiotic. These particles were found to have a diameter of 120 nm and a zeta potential of 20.0 mV. Both fluorescent and antimicrobial studies demonstrated that based on electrostatic interaction, negatively charged AuC attached to the liposome's positively charged surface and stabilized liposomes in a neutral pH environment (pH = 7.4). Upon entering the skin's acidic environment (pH = 4), AuC detached from the liposome's surface and liposomes could fuse with P. acnes residing in the pores. Furthermore, toxicity studies showed that AuC-liposomes did not induce any significant toxicity, while two of the leading over-the-counter therapies, benzoyl peroxide and salicylic acid, generated substantial skin irritation.

  16. Periungual Pyogenic Granuloma-Like Lesions During Isotretinoin Treatment for Acne: Two Case Reports and a Literature Review

    Full Text Available Periungual pyogenic granuloma-like lesions are not uncommon side effects of isotretinoin therapy, but these cases are relatively infrequently reported. Excessive granulation tissue appeared in two patients receiving oral isotretinoin therapy for severe acne. Once isotretinoin was discontinued, the outgrowths resolved spontaneously in both patients. It is probably an idiosyncratic reaction to isotretinoin which renders the skin more susceptible to extracellular matrix and blood vessel formation. Moreover, similar lesions may be observed particularly with newer targeted therapies, such as inhibitors of epidermal growth factor receptor (EGFR and mitogen-activated protein kinase kinases (MEKs. EGFR inhibitors associated painful periungual inflammation (paronychia, which often arises from the nail wall during newer targeted therapies, has been classified in the third major group of dermatologic toxicity. Cutaneous toxicity may be interpreted as a stress response that affects epidermal homeostasis. In the cell, stress signals are transmitted to effectors which then produce an inflammatory response.

    The aim of this study was to evaluate the efficacy of autologous platelet-rich plasma (PRP) combined with erbium fractional laser therapy for facial acne or acne scars. PRP combined with erbium fractional laser therapy was used for the treatment of 22 patients, including 16 patients who suffered from facial acne scars and 6 patients who suffered from acne scars concomitant with acne. Whole blood (40 ml) was collected from each patient, and following differential centrifugation, PRP was harvested. After using an erbium fractional laser, we applied PRP to the entire face of every patient. Digital photos were taken before and after the treatment for evaluation by dermatologists and the patients rated the efficacy on a 5-point scale. The erythema was moderate or mild, while its total duration was 50%, and 91% of the patients were satisfied; no acne inflammation was observed after treatment. PRP combined with erbium fractional laser therapy is an effective and safe approach for treating acne scars or acne, with minimal side-effects, and it simultaneously enhanced the recovery of laser-damaged skin.

  18. A randomized, double-blind, multicenter, parallel group study to compare relative efficacies of the topical gels 3% erythromycin/5% benzoyl peroxide and 0.025% tretinoin/erythromycin 4% in the treatment of moderate acne vulgaris of the face.

    Combination treatments for acne vulgaris, such as Benzamycin (3% erythromycin/5% benzoyl peroxide) and Stievamycin (0.025% tretinoin/erythromycin 4%), reduce bacterial growth, which contributes to the inflammatory lesions typical of adolescent acne, and also decrease the epidermal cell compaction which may form the characteristic noninflammatory comedone. Both agents contain erythromycin to reduce the growth of Propionibacterium acnes in skin. Benzoyl peroxide has antibiotic activity as well as anticomedogenic properties. Tretinoin may increase the turnover of epidermal cells and loosen the cells compacted to form comedones. A combination preparation containing the two antibiotics may reduce the development of resistance; the combination preparation containing tretinoin and erythromycin will have an antibiotic effect as well as acting on differentiation. This multicenter, randomized, double-blind, parallel group study compared the effectiveness of 3% erythromycin/5% benzoyl peroxide and 0.025% tretinoin/erythromycin 4%, each applied twice daily in patients with moderate acne vulgaris. Overall physician and patient ratings of severity of acne symptoms were performed at baseline and at weeks 2, 4, 8, and 12. At baseline the two treatment groups had similar disease severity. The number of papules, pustules, and comedones was reduced in both treatment groups at week 12, and the reductions were not significantly different between the two comparators. Global physician rating of improvement was significantly higher in the 3% erythromycin/5% benzoyl peroxide group compared with the 0.025% tretinoin/erythromycin 4% group; however, there was no significant difference in global patient ratings between the two treatment groups. An aggregate score was produced, for both physician rating and patient rating, by adding up individual symptom severity ratings. Compared with 0.025% tretinoin/erythromycin 4%, 3% erythromycin/5% benzoyl peroxide provided significantly greater reduction

    Acne is a frequent dermatologic disease of the teenagers. Methodology of antiacne preparations clinical trials has evolved recently, leading to better comprehension of acne treatment on acne lesions. The main rules for good clinical evaluation of acne treatments are: an objective counting of each individual lesions on a defined area (face, back), a global acne assessment, a therapy duration from 1 to 3 months or more, a skin safety evaluation for erythema, desquamation, dryness, itching, burning and oiliness with a 0 to 3 scoring system.

    Fractional microneedling radiofrequency (FMR) is one of the promising methods in acne treatment. Moreover, bipolar radiofrequency (BR) generates heat thereby which induces neocollagenosis. FMR may have the potential to be a safe and effective treatment for the patients both with acne and acne scar. This study was performed to compare the efficacy and safety of FMR and BR in acne and acne scar treatment. Furthermore, mechanism of the FMR treatment was investigated through skin tissues obtained from subjects. Twenty subjects with mild-to-moderate acne and acne scars were treated in a split-face manner with FMR and BR. Two sessions of treatment was done 4 weeks apart in a total 12-week prospective single-blind, randomized clinical trial. Clinical assessment and sebum measurement were carried out for the evaluation of efficacy and safety. Skin tissues were acquired for investigation of molecular changes. FMR was more effective for acne scar especially in icepick and boxcar scar compared to BR. Both inflammatory and non-inflammatory acne lesions decreased by 80 and 65 % in the FMR-treated side at the final visit of 12 weeks, respectively. FMR treatment resulted in significant reduction of sebum excretion. Both treatments showed no severe adverse effects other than erythema. The FMR showed superior efficacy in acne and acne scar compared with BR. Increased expression of TGFβ and collagen I and decreased expression of NF-κB, IL-8 are suggested to involve in the improvement of acne scar and acne lesion by FMR.

    Acne vulgaris (acne) is a common affliction in adolescence and is a growing problem in adult women. Despite an increasing awareness of acne in the adult female population, there is a lack of good prospective studies assessing the severity, distribution, and differential response to treatment in this group. The long-held dogma that acne in adult women develops on the lower one-third of the face has been recently challenged, and here the authors critically review data from available literature. Moreover, while adult female acne has traditionally been defined as disease in women over age 25, it is the authors’ experience that this group is subdivided into women ages 25 to 44 years, separate from perimenopausal patients, ages 45 years and up. While there is no data specifically comparing these two groups, the authors will review the existing data and provide practical recommendations based on our experience in treating these groups of patients. Finally, while there is a lack of data on this subject, it is the group’s opinion that adherence to medication regimens is likely higher in women than men, which influences therapeutic outcomes.

    The aim of this paper was to evaluate efficacy and tolerability of a topical gel (ACNAID TM gel medical device) containing 3% hydrogen peroxide (HPO), 1.5% salicylic acid (SA) and 4% D-panthenol (D-p) in the treatment of mild-moderate acne, comparing it with a previous formulation (ACNAID TM gel Cosmetic) containing 4% HPO, 0.5% SA, 4% D-p. Twenty patients of both sex with mild-moderate acne have been selected. The topical gel was applied twice a day for 60 days. Evaluations included: Global Acne Grading System (GAGS); lesions count; photographic assessment; a questionnaire to assess the tolerability. The results have been compared with those obtained in a previous study conducted with the formulation containing 4% HPO, 0.5% SA, 4% D-p. The GAGS score showed a reduction of 43% from T0 to T1 and of 61% from T0 to T2. Count of lesions: comedones reduction of 62% from T0 to T1 and of 95% from T0 to T2; papules reduction of 49% from T0 to T1 and of 68% from T0 to T2; pustules reduction of 75% from T0 to T1 and of 100% from T0 to T2. Digital images showed a significant reduction of acne lesions. At T2 the tolerability of the topical product was excellent according to 83% of patients and good according to 17% of patients. The topical gel has demonstrated to be effective and safe for treatment of mild to moderate acne. No patients reported side effects. These results are superior to those obtained in the previous study.

    In the present study, antibacterial activity of four kinds of phloroglucinol derivatives extracted from Dryopteris fragrans (L.) Schott against S. aureus, S. epidermidis and P. acnes has been tested. Aspidin BB exerted the strongest antibacterial activity with minimal inhibition concentration (MIC) values ranging from 7.81 to 15.63 μg/mL. The time-kill assay indicated that aspidin BB could kill P. acnes completely at 2 MIC (MBC) within 4 h. By using AFM, we demonstrated extensive cell surface alterations of aspidin BB-treated P. acnes. SDS-PAGE of supernatant proteins and lipid peroxidation results showed that aspidin BB dose-dependently affected membrane permeability of P. acnes. DNA damage and protein degradation of P. acnes were also verified. SDS-PAGE of precipitated proteins revealed possible targets of aspidin BB, i.e., heat shock proteins (26 kDa) and lipase (33 kDa) which could all cause inflammation. Aspidin BB also seriously increased the inhibition rate of lipase activity from 10.20 to 65.20 % to possibly inhibit the inflammation. In conclusions, the effective constituents of D. fragrans (L.) Schott to treat acne might be phloroglucinol derivatives including aspidin BB, aspidin PB, aspidinol and dryofragin. Among this, aspidin BB inhibited the growth of P. acnes by disrupting their membrane, DNA and proteins and finally leaded to the cell death. The obtained data highlighted the potential of using aspidin BB as an alternative treatment for acne vulgaris.

    'Fragile skin', or skin with lower resistance to aggressors, can be broadly classified into four causal categories: constitutional (age-dependent or associated with specific vulnerable locations on the body, e.g. eyelids), pathological (related to disease), circumstantial (related to environmental or internal factors, e.g. stress) and iatrogenic (caused by medical interventions or treatments). In this supplement, we focus on the fourth category, the iatrogenic origin of fragile skin and the role that dermo-cosmetics can have in restoring the natural protective function of the skin following treatments for skin diseases and medical interventions. We present epidemiological data on the prevalence of fragile skin in three different geographical regions, and the results of two randomized controlled studies investigating the efficacy and tolerability of dermo-cosmetics in combination with topical acne treatment and following physical skin damage. Overall, we found that prevalence across the three regions (23% in Germany, 41% in UAE, 56% in Taiwan) reflected previous global estimates (24-53%) across skin types, with significant associations found with environmental and lifestyle factors, such as stress, humidity and pollution. The iatrogenic effects of topical acne treatments can result in poor compliance or use of over-the-counter moisturizers, which may reduce treatment efficacy. Dermo-cosmetics were found to aid in restoration of fragile skin caused by the acne topical retinoid treatment adapalene 0.1% gel, by reducing transepidermal water loss and improving skin hydration, as well as reducing the side-effects such as skin irritation that are frequently associated with topical retinoids. Additionally, dermo-cosmetic products were found to accelerate wound closure following skin damage in a laser ablation model and reduced the duration of post-procedural side-effects such as itching and burning. © 2017 European Academy of Dermatology and Venereology.

    Acne may present in neonates, infants, and small children. Neonatal and infantile acne vulgaris are not considered to be rare. The presentation of acne in this patient population sometimes represents virilization and may portend later development of severe adolescent acne. Neonatal and infantile acne vulgaris must be distinguished from other cutaneous disorders seen in newborns and infants. Infantile acne tends to be more pleomorphic and inflammatory, thus requiring more vigorous therapy than neonatal acne.

    Dapsone gel, 5% is administered twice daily for the treatment of acne vulgaris, and some patients may find adherence challenging. The study objective was to assess the efficacy and safety, compared with vehicle, of acne treatment with a recently FDA-approved, once-daily formulation of dapsone gel, 7.5%, with a 50% greater concentration of dapsone. This 12-week, randomized, double-blind, vehicle-controlled, multicenter clinical trial enrolled patients aged 12 years and older with 20-50 facial inflammatory lesions, 30-100 facial noninflammatory lesions, and an acne grade of 3 (moderate) on the Global Acne Assessment Score (GAAS). Patients were randomized (1:1 ratio) to topical dapsone gel, 7.5% or vehicle once daily for 12 weeks. Investigators assessed GAAS success rate (proportion of patients with a GAAS of 0 or 1) and percent change from baseline in inflammatory, noninflammatory, and total lesions. The intent-to-treat population comprised 2238 patients (1118 in the dapsone gel, 7.5% group and 1120 in the vehicle group). The GAAS success rates were 29.8% for the dapsone gel, 7.5% group and 20.9% for the vehicle group (P<0.001) at week 12. At week 12, mean inflammatory lesions decreased from baseline by 53.8% and 47.3%, noninflammatory lesions decreased by 45.9% and 40.4%, and total lesions decreased by 48.9% and 43.2% for the dapsone gel, 7.5% group and the vehicle group, respectively (all, P<0.001). The incidence of treatment-emergent adverse events was similar for dapsone gel, 7.5% (17.6%) and vehicle (17.1%). Most adverse events were mild to moderate in severity. The most frequently reported increase in severity for all of the dermal tolerability scales was from "none" to "mild." Dapsone gel, 7.5% applied topically once daily is an effective, safe, and well-tolerated treatment for acne vulgaris. Improvements in acne severity and lesions were observed over the 12-week course of treatment. J Drugs Dermatol. 2016;15(8):962-969.

    More than 99% acne patients suffer from acne vulgaris. While diagnosing the severity of acne vulgaris lesions, dermatologists have observed inter-rater and intra-rater variability in diagnosis results. This is because during assessment, identifying lesion types and their counting is a tedious job for dermatologists. To make the assessment job objective and easier for dermatologists, an automated system based on image processing methods is proposed in this study. There are two main objectives: (i) to develop an algorithm for the enhancement of various acne vulgaris lesions; and (ii) to develop a method for the segmentation of enhanced acne vulgaris lesions. For the first objective, an algorithm is developed based on the theory of high dynamic range (HDR) images. The proposed algorithm uses local rank transform to generate the HDR images from a single acne image followed by the log transformation. Then, segmentation is performed by clustering the pixels based on Mahalanobis distance of each pixel from spectral models of acne vulgaris lesions. Two metrics are used to evaluate the enhancement of acne vulgaris lesions, i.e., contrast improvement factor (CIF) and image contrast normalization (ICN). The proposed algorithm is compared with two other methods. The proposed enhancement algorithm shows better result than both the other methods based on CIF and ICN. In addition, sensitivity and specificity are calculated for the segmentation results. The proposed segmentation method shows higher sensitivity and specificity than other methods. This article specifically discusses the contrast enhancement and segmentation for automated diagnosis system of acne vulgaris lesions. The results are promising that can be used for further classification of acne vulgaris lesions for final grading of the lesions. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Acne can have a significant physical, emotional, and social impact on an individual. Many different treatment options are available for the treatment of acne vulgaris. Commonly used topical treatments include benzoyl peroxide, antibiotics, sulfur and sodium sulfacetamide, azelaic acid, and retinoids. Systemic treatment is frequently used and includes the use of systemic antibiotics, oral contraceptives, antiandrogens, and retinoids. Other treatment modalities exist such as the use of superficial chemical peels as well as using laser and light devices for the treatment of acne. With the multitude of treatment options and the rapidly expanding newer technologies available to clinicians, it is important to review and be aware of the current literature and studies regarding the treatment of acne vulgaris.Keywords: acne vulgaris, treatment, benzoyl peroxide, antibiotics, retinoids, lasers

    2017-01-01

    INTRODUCTION: Although acne vulgaris is common in adolescents, information on their understanding of acne is minimal. OBJECTIVES: To evaluate the perceptions and beliefs of Saudi youth on acne. MATERIALS AND METHODS: Three hundred twenty-nine male students (aged 13–22 years) from 6 secondary schools in the Eastern Saudi Arabia completed a self-reported questionnaire on knowledge, causation, exacerbating and relieving factors of acne. Data were analyzed by SPSS version 15.0. Results of subjects with acne, a family history of acne, and parents' educational levels were compared. Differences between the analyzed groups were assessed by a Chi-square test; p ≤ 0.05 was considered statistically significant. RESULTS: Over half (58.9%) of the participants considered acne a transient condition not requiring therapy. Only 13.1% knew that the proper treatment of acne could take a long time, even several years. Over half (52%) thought acne can be treated from the first or after few visits to the doctor. Popular sources of information were television/radio (47.7%), friends (45.6%), and the internet (38%). Only 23.4% indicated school as a source of knowledge. Reported causal factors included scratching (88.5%) and squeezing (82.1%) of pimples, poor hygiene (83.9%), poor dietary habits (71.5%), and stress (54.1%). Ameliorating factors included frequent washing of the face (52.9%), exercise (41.1%), sunbathing (24.1%), and drinking of mineral water (21%). The correlations of these facts are discussed. CONCLUSION: Results of this study point out that misconceptions of acne are widespread among Saudi youth. A health education program is needed to improve the understanding of the condition.

    2013-01-01

    Full Text Available The role of Propionibacterium acnes in acne and in a wide range of inflammatory diseases is well established. However, P. acnes is also responsible for infections involving implants. Prolonged aerobic and anaerobic agar cultures for 14 days and broth cultures increase the detection rate. In this paper, we review the pathogenic role of P. acnes in implant-associated infections such as prosthetic joints, cardiac devices, breast implants, intraocular lenses, neurosurgical devices, and spine implants. The management of severe infections caused by P. acnes involves a combination of antimicrobial and surgical treatment (often removal of the device. Intravenous penicillin G and ceftriaxone are the first choice for serious infections, with vancomycin and daptomycin as alternatives, and amoxicillin, rifampicin, clindamycin, tetracycline, and levofloxacin for oral treatment. Sonication of explanted prosthetic material improves the diagnosis of implant-associated infections. Molecular methods may further increase the sensitivity of P. acnes detection. Coating of implants with antimicrobial substances could avoid or limit colonization of the surface and thereby reduce the risk of biofilm formation during severe infections. Our understanding of the role of P. acnes in human diseases will likely continue to increase as new associations and pathogenic mechanisms are discovered.

    BACKGROUND Acne is a common disease in adolescents, but there are no epidemiological data for acne in Brazil. OBJECTIVES To estimate the prevalence and degree of acne in adolescents from Sao Paulo and study socio-demographic factors, family history and lifestyle, associated with the disease. METHODS Cross-sectional study with 452 adolescents aged between 10 and 17 (mean=13.3 years), students from elementary and high school, examined by 3 independent evaluators. RESULTS 62.4% were female, 85.8% white and 6.4% were aged 14. The prevalence was 96.0% and increased with age - all students over 14 had acne. The most prevalent form of acne was comedonal (61.1%), followed by mild (30.6%) and moderate (7.6%) papular-pustular, which affected mostly the face (97.5%). About half of the adolescents reported family history for acne in mother or father, and 20.6% reported previous treatment for acne. There was a higher chance of presenting non-comedonal acne with increased age (pacne in adolescents varies widely due to the clinical features and diagnostic methods used. Adolescents whose brothers/sisters had acne (OR=1.7-p=0.027) and those over 13 (OR=8.3-pacne. CONCLUSION This study showed high prevalence of acne in adolescents from Sao Paulo, predominantly the comedonal form on the face, with a higher chance of presenting non-comedonal acne with increased age.

    Acne vulgaris is a common inflammatory skin disease. Vitamin D deficiency plays a role in many inflammatory skin diseases. It may play a role in pathogenesis of acne vulgaris. This study aimed to assess serum levels of 25 hydroxy vitamin D in patients with acne vulgaris before and after treatment with isotretinoin and its relation with acne vulgaris severity. Ninety patients with acne vulgaris and 60 age-sex matched healthy subject as controls have been recruited in this study. Patients were treated with 0.75 mg/kg/d isotretinoin for 3 months. Serum level of 25 hydroxy vitamin D has been measured at baseline and after treatment. Serum levels of 25 hydroxy vitamin D were significantly higher in patients with acne vulgaris than healthy controls (P = .001). There was a significant inverse relation between level of 25 hydroxy vitamin D and severity of acne vulgaris before treatment (P = .001). Serum levels of 25 hydroxy vitamin D were significantly increased after isotretinoin treatment in patients with acne vulgaris (P = .001). This study concluded that vitamin D may play a potential role in pathogenesis of acne vulgaris or acne vulgaris may have a negative effect on vitamin D synthesis. Further studies are needed to confirm these potential relations. © 2018 Wiley Periodicals, Inc.

    The Global Alliance to Improve Outcomes in Acne published recommendations for the management of acne as a supplement to the Journal of the American Academy of Dermatology in 2003. The recommendations incorporated evidence-based strategies when possible and the collective clinical experience of the group when evidence was lacking. This update reviews new information about acne pathophysiology and treatment-such as lasers and light therapy-and relevant topics where published data were sparse in 2003 but are now available including combination therapy, revision of acne scarring, and maintenance therapy. The update also includes a new way of looking at acne as a chronic disease, a discussion of the changing role of antibiotics in acne management as a result of concerns about microbial resistance, and factors that affect adherence to acne treatments. Summary statements and recommendations are provided throughout the update along with an indication of the level of evidence that currently supports each finding. As in the original supplement, the authors have based recommendations on published evidence as much as possible.

    Using the technique of simultaneous, symmetrical paired comparisons, a medicated cleansing pad that can be easily used at work or at school as an adjunctive in the treatment of acne vulgaris was evaluated.The experimental pads were significantly beneficial in reducing skin oiliness and in clinical improvement of the acne. Response to standard acne therapy was faster when the pads were used adjunctively, although the significant results seen initially tended to even out as therapy continued. Use of the medicated pads produced no untoward side effects and were well accepted by patients.

    Acne therapies that are able to show efficacious treatment of acne lesions as well as to address the issues of oiliness and shine control may be particularly appropriate for the treatment of patients with acne vulgaris that is accompanied by oily skin and facial shine. The microsphere delivery system (MDS), a novel delivery technology for topical therapy, can be customized to optimize product attributes, including oil absorption. Clinical trials have clearly established the efficacy and tolerability of such MDS formulations in the treatment of acne. In addition, studies have shown that the use of products formulated with an MDS provides a more significant reduction in facial shine than non-MDS acne therapy, as well as a reduction in facial sebum accumulation relative to control. Future clinical research should aim to further delineate the effect of individual topical acne treatment formulations on oiliness and shine.

  1. Effects of bee venom against Propionibacterium acnes-induced inflammation in human keratinocytes and monocytes.

    Propionibacterium acnes (P. acnes) cause inflammatory acne and play an important role in the pathogenesis of acne by inducing inflammatory mediators. P. acnes contributes to the inflammatory responses of acne by activating inflammatory cells, keratinocytes and sebocytes to secrete pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-8. Bee venom has traditionally been used in the treatment of certain immune-related diseases. However, there has not yet been a robust trial to prove the therapeutic effect of bee venom in skin inflammation. The aim of the present study was to investigate anti-inflammatory properties of bee venom in skin inflammation induced by P. acnes using keratinocytes (HaCaT) and monocytes (THP-1). P. acnes is known to stimulate the production of pro-inflammatory cytokines such as IL-1, IL-8, IL-12 and TNF-α. In the present study, the production of interferon-γ (IFN-γ), IL-1β, IL-8 and TNF-α was increased by P. acnes treatment in HaCaT and THP-1 cells. By contrast, bee venom effectively inhibited the secretion of IFN-γ, IL-1β, IL-8 and TNF-α. Furthermore, P. acnes treatment activated the expression of IL-8 and toll-like receptor 2 (TLR2) in HaCaT cells. However, bee venom inhibited the expression of IL-8 and TLR2 in heat-killed P. acnes. Based on these results, it is concluded that bee venom has an effective anti-inflammatory activity against P. acnes in HaCaT and THP-1 cells. Therefore, we suggest that bee venom is an alternative treatment to antibiotic therapy of acne.

    To evaluate efficacy, safety, and tolerability of a fixed combination clindamycin phosphate 1.2% and benzoyl peroxide 3.75% (clindamycin-BP 3.75%) aqueous gel in moderate to severe acne vulgaris. A total of 498 patients, 12-40 years of age, were randomized to receive clindamycin-BP 3.75% or vehicle in a double-blind, controlled 12-week, 2-arm study evaluating safety and efficacy using inflammatory and noninflammatory lesion counts, Evaluator Global Severity Scores (EGSS) and subject self-assessment (SSA). In addition, patients completed a patient satisfaction survey (PSS), acne-specific QoL questionnaire, and assessed their facial skin for shininess/oiliness. Clindamycin-BP 3.75% demonstrated statistical superiority to vehicle in reducing both inflammatory and noninflammatory lesions and acne severity. Clindamycin-BP 3.75% showed greater efficacy relative to vehicle in assessments of skin oiliness, SSA and PSS. No substantive differences were seen in cutaneous tolerability among treatment groups and no patients discontinued treatment with Clindamycin-BP 3.75% because of adverse events. Data from controlled studies may differ from clinical practice. It is not possible to determine the contributions from the individual active ingredients. Clindamycin-BP 3.75% provides statistically significant greater efficacy than vehicle with a favorable safety and tolerability profile.

    Acne is a chronic skin disease characterised by inflamed spots and blackheads on the face, neck, back, and chest. Cysts and scarring can also occur, especially in more severe disease. People with acne often turn to complementary and alternative medicine (CAM), such as herbal medicine, acupuncture, and dietary modifications, because of their concerns about the adverse effects of conventional medicines. However, evidence for CAM therapies has not been systematically assessed. To assess the effects and safety of any complementary therapies in people with acne vulgaris. We searched the following databases from inception up to 22 January 2014: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL; 2014,Issue 1), MEDLINE (from 1946), Embase (from 1974), PsycINFO (from 1806), AMED (from 1985), CINAHL (from 1981), Scopus (from 1966), and a number of other databases listed in the Methods section of the review. The Cochrane CAM Field Specialised Register was searched up to May 2014. We also searched five trials registers and checked the reference lists of articles for further references to relevant trials. We included parallel-group randomised controlled trials (or the first phase data of randomised cross-over trials) of any kind of CAM, compared with no treatment, placebo, or other active therapies, in people with a diagnosis of acne vulgaris. Three authors collected data from each included trial and evaluated the methodological quality independently. They resolved disagreements by discussion and, as needed, arbitration by another author. We included 35 studies, with a total of 3227 participants. We evaluated the majority as having unclear risk of selection, attrition, reporting, detection, and other biases. Because of the clinical heterogeneity between trials and the incomplete data reporting, we could only include four trials in two meta-analyses, with two trials in each meta-analysis. The categories of CAM included

    2016-09-01

    Although acne is not an infectious disease, oral antibiotics have remained a mainstay of treatment over the last 40 years. The anti-inflammatory properties of oral antibiotics, particularly the tetracyclines, are efficacious in treating inflammatory acne lesions. Common prescribing practices in Dermatology exert significant selection pressure on bacteria, contributing to the development of antibiotic resistance. Antibiotic use for acne not only promotes resistance in Propionibacterium acnes, but also affects other host bacteria with pathogenic potential. This review will summarize the commonly used treatments for acne vulgaris, and how they should be combined as rational treatment. The indications for using oral antibiotics in acne will be highlighted. Strategies described in the literature to conserve the utility of oral antibiotics will be summarized. These include limiting the duration of antibiotic therapy, concomitant use of a topical non-antibiotic agent, use of subantimicrobial dose doxycycline, and the introduction of topical dapsone. © 2016 Wiley Periodicals, Inc.

    Thirty strains of Propionibacterium acnes were grown in basal salt medium containing lecithin as a lipid substrate and in other media. The cultures were assayed for production of lipase (measured as fatty acid esterase) and other exoenzymes. Lipase was assayed spectrophotometrically; other enzymes were assayed using the API ZYM system (Analytab Products Inc., Plainview, NY). Substance for lipase were alpha- and beta-naphthol esters of propionic, butyric, valeric, caprylic, lauric, myristic, and oleic acids. All strains showed fatty acid esterase activity. Using the API ZYM system 19 enzymes were detected, 8 of which were found frequently and had high activity in most strains. Acid and alkaline phosphatases, phosphoamidase, ester lipase, trypsin-chymotrypsin-like proteases, beta-glucuronidase (80%), beta-galactosidase (80%), and N-acetyl-beta-glucosaminidase were found. Many enzymes of P. acnes appear to be adaptive, dependent on the culture substrate.

    Acne vulgaris affects about 85% of adolescents, often extending into adulthood. Psychosocial impact of acne on health-related quality of life (QoL) has been identified, but it remains under-evaluated, especially in Indian patients. This study was aimed to assess the impact of acne and its sequelae on the QoL. This was a hospital-based, prospective, cross-sectional study done between June and November 2014 on 114 consenting patients above 15 years of age with acne vulgaris. Acne vulgaris and its sequelae were graded, and QoL was assessed by using Dermatology Life Quality Index (DLQI) questionnaire. Most cases (64%) were between 15 and 20 years. Females (57%) outnumbered males. Facial lesions (61.4%) and grade II acne were most common. Mean DLQI score was 7.22. DLQI scores were statistically influenced by the age of the patient, duration and grade of acne, acne scar, and postacne hyperpigmentation. This study showed significant impairment of QoL in acne patients. Assurance and counseling along with early treatment of acne vulgaris are important to reduce disease-related psychosocial sequelae and increase the efficacy of treatment.

    Full Text Available An optimized therapeutic regimen involving a non-ablative fractionated laser or radiofrequency therapy for acne scars has not yet been established. To evaluate whether the combination of a non-ablative fractional laser (NAF and fractional micro-needling radiofrequency (FMR has clinical advantages for the treatment of atrophic acne scars compared with NAF alone, a 16-week prospective, randomized split-face study was performed. Each facial side of a patient was treated with 3 sessions of either NAF with FMR or NAF alone, with a 4-week interval between each session. Although both sides demonstrated significant decreases in the échelle d’évaluation clinique des cicatrices d’acné (ECCA score, the facial side treated using the combination regimen demonstrated greater improvement in ECCA score regarding degree and onset time than the NAF-treated side. Histopathological and immunohistochemical results confirmed the clinical findings. This study demonstrated that a combination regimen involving NAF and FMR could be a viable option with satisfactory efficacy.

    Full Text Available BACKGROUND Acne is a common problem in adolescent children and has a considerable impact on their quality of life. AIMS The impact of acne on quality of life (QoL in Indian adolescent patients remains undocumented. The study was undertaken to detect the impact of acne vulgaris in adolescents on the QoL using 2 questionnaires: The Children’s Dermatology Life Quality Index (CDLQI and the Cardiff Acne Disability Index (CADI. MATERIALS AND METHODS This was a hospital-based, prospective, cross-sectional, pre-structured, questionnaire-based study done on 140 consenting individuals, who attended the Acne Clinic of our Dermatology Outpatient Department. Acne vulgaris was graded using simple grading system. QoL was measured using a combination of skin disease-specific (Children’s Dermatological Life Quality Index (CDLQI and acne-specific (Cardiff Acne Disability Index (CADI questionnaires. RESULTS The study population included 140 cases with a female to male ratio of 1.5:1. Comedones (123, 87.9% were the most common type of lesion. Grade I acne was the most common clinical type (76.4%. There was a statistically significant difference between acne severity and gender. The overall mean CDLQI score (7.21 of max. 30 and the overall mean CADI score (4.8 of max. 15 were low, indicating a mild impairment of QoL among adolescents. Statistically significant association was noted between CDLQI and CADI scores and grade of acne. There was no statistically significant association noted between CDLQI and CADI scores and gender. CONCLUSION Though acne had impact on patient’s QoL, it was less severe in our study. The CDLQI and CADI questionnaires represent simple and reliable instruments for the assessment of QoL among adolescents and should be incorporated when managing acne patients to provide better and appropriate care.

    2017-02-01

    Dapsone 7.5% gel (Aczone ® ) is indicated for the once-daily topical treatment of acne vulgaris in patients aged ≥12 years. Dapsone is a sulfone antibacterial with anti-inflammatory actions, which are thought to be largely responsible for its efficacy in treating acne vulgaris. In two phase III trials of 12 weeks' duration in patients aged ≥12 years with moderate acne vulgaris, once-daily dapsone 7.5% gel reduced acne severity (as per the Global Acne Assessment Score) and lesion counts versus vehicle. The benefits of dapsone 7.5% gel over vehicle were seen as early as week 2 for inflammatory lesion counts, and from week 4 or 8 for other outcomes. Dapsone 7.5% gel was well tolerated, with a low incidence of treatment-related adverse events, with the majority of adverse events being administration-site related and mild or moderate in severity. Thus, dapsone 7.5% gel is an effective and well tolerated option for the topical treatment of acne vulgaris in patients aged ≥12 years, with the convenience of once-daily application.

    The aim of this study is to evaluate the frequency of dosing topical antibiotics as monotherapy in the treatment of acne vulgaris, and physician specialty prescribing these medications. This study is a retrospective review of all visits with a sole diagnosis of acne vulgaris (ICD-9-CM code 706.1) found on the National Ambulatory Medical Care Survey (NAMCS) in 1993-2010. We recorded the number of visits surveyed where acne vulgaris was the sole diagnosis, number of visits where topical antibiotics were the only treatment prescribed, and the specialty of physician in each encounter. Topical erythromycin or clindamycin were the sole medication prescribed in 0.81% of the visits recorded, with 60% of these prescriptions arising from dermatologists and 40% from non-dermatologists. The trend of prescribing topical antibiotic monotherapy is declining (p acnes to topical antibiotic regimens has led to the need to re-evaluate the use of topical antibiotics in the treatment of acne vulgaris. While the rate of topical antibiotic monotherapy is declining, their use should be reserved for situations where the direct need for antibiotics arises. If a clinician feels that antibiotics are a necessary component to acne therapy, they should be used as part of a combination regimen.

    The purpose of this study was to assess the impact of acne on the quality of life. Its secondary objective was to assess the influence of gender of students and severity of symptoms on the quality of life. . A cross sectional study was conducted on 100 students at Sultan Qaboos University (SQU) (40 males and 60 females) diagnosed with acne who attended the Student Clinic during a period of three months from September to December 2009. The Acne Quality Of Life index (Acne-QoL) questionnaire was used to assess the patient's quality of life in four different domains: self-perception, social, emotional, and acne symptoms. . Acne affected all areas of the patients, quality of life with the emotional domain found to be the most affected. Overall, female patients reported more adverse QoL effects. The mean score for self-perception for female students was 2.5 and 2.8 for males (p=0.300). The role-social domain approached a significant difference between genders (p=0.078). There was a statistically significant correlation between severity of acne symptoms and the other three domains. The correlation was highest between acne symptoms score and self-perception score. . This study showed that acne affects the quality of life of affected SQU students treated by primary care physicians at the Student Clinic. Therefore, physicians should take into account the effect of acne on the persons' quality of life when individualizing treatment.

    Acne vulgaris is a common dermatological disorder with a multifactorial pathogenesis. Oxidative status has been implicated in the pathogenesis of several skin diseases, including acne. This study was aimed to investigate the levels of oxidative stress biomarkers in acne vulgaris patients with varying severities. The study involved 156 patients with acne and 46 healthy human controls. Based on clinical examination, patients were grouped into 3 subgroups as follows: mild, moderate, and severe acne. Oxidative stress was examined by measuring plasma levels of catalase (CAT), superoxide dismutase (SOD), total antioxidant capacity (TAC), and malondialdehyde (MDA). Plasma levels of MDA in acne patients were significantly higher as compared with that of the controls, whereas activities of the antioxidant enzymes SOD and CAT were lower. Moreover, TAC was also low in acne patients as compared with that of the controls. Higher MDA levels in the severe acne subgroup as compared with that of the mild and moderate subgroups were also observed. Furthermore, in the severe acne subgroup, a significant negative correlation was observed between MDA and CAT levels. The data suggests that oxidative stress plays a key role in acne progress and may be employed as a biomarker index to assess the disease's activity and to monitor its treatment.

    Background: Acne vulgaris is a common skin condition which affects most adolescents. It has a major impact on quality of life and psychosocial well-being. Aims: The aims of the study were to examine the psychosocial effects of acne on adolescents and changes in quality of life, and to reveal any difference in the possible effect between genders. In addition, an investigation of the association between acne severity and quality of life as well as psychosocial stress was conducted. Materials and Methods: The present study included 164 adolescents with a mean age of 12–18 years and was diagnosed with acne vulgaris without any previous treatment. The control group consisted of 188 healthy volunteers. Acne severity was evaluated by the global acne grading system. All patients filled in a Children's Dermatology Life Quality Index, Pediatric Quality of Life Questionnaire (PedsQL), and a Strength and Difficulties Questionnaire (SDQ). Results: The scores of SDQ and PedsQL were significantly lower in the case group. There was no significant correlation found between the genders in the control group for acne severity and scale scores. No significant correlation was found between acne severity and psychosocial challenges. Conclusions: The results of the present study show that acne has a significant effect on quality of life for adolescents, and this has an impact on their psychosocial life. Another important finding of the present study is that worsening in quality of life is not affected by some factors such as duration, severity of acne and age. PMID:29692454

    Full Text Available Background and Design: Although acne vulgaris is generally regarded as a disease of adolescence period, it can occur in infancy, early childhood and prepubertal period. Acne may emerge as the first sign of pubertal maturation. In our study, we aimed to determine the acne prevalence in primary school children, then, evaluate the pubertal signs in those children; examine the correlation of the presence and severity of acne with pubertal signs, and finally, revise the concept of prepubertal acne. Materials and Methods: A thousand students from 2 schools in Istanbul were included in the study. Age, gender, and the presence, localization and severity of acne were recorded. Acne severity was evaluated using the Orfanos-Gollnick Acne Grading System while a validated self evaluation form which had been developed by Morris and Udry was used to evaluate pubertal stage. Data were evaluated statistically. Results: Five hundred and thirty-four male and 466 female primary school children, with an age range of 7 to 11, were included in the study. Acne was determined in 11.5% of the students. 20% of girls and 4% of boys had acne. Comparing acne presence and age, the average age was higher in group with acne than those with no acne. The mean age of children with grade 1 acne was lower than those with grade 2 acne. All the students with acne had mid-facial acne. Comparing acne presence and pubertal symptoms, the rate of the presence of acne was higher in pubertal girls. No acne was observed in prepubertal boys. Evaluating acne severity and pubertal signs, the difference between prepubertal and pubertal girls was not significant. Comparing acne and telarche stages, the group without acne had lower telarche rates. Comparing acne and pubertal stages, children with acne had advanced puberty. Conclusion: Our study denotes that acne prevalence is related to pubertal maturation and age; while it does not support the hypothesis that acne is the first sign of pubertal

    Several acne grading systems have been described, but consensus is lacking on which shows superiority. A standardized system would facilitate therapeutic decisions and the analysis of clinical trial data. To assess the feasibility, reliability, validity and sensitivity to change of the Spanish Acne Severity Scale (EGAE). A Spanish, multicentre, prospective, observational study was performed in patients with facial, back or chest acne assessed using EGAE, Leeds Revised Acne Grading system (LRAG) and lesion count. Clinicians answered 4 questions regarding EGAE use and time employed. Patients were evaluated at baseline and after 5±1 weeks. Four additional blinded observers, all dermatologists, evaluated patients' pictures using EGAE and LRAG. In total, 349 acne locations were assessed in 328 patients. Of the dermatologists, 95.6% (CI: 92.9-97.5%) reported that EGAE was easy to use, and 75% used it in 0.85; p<0.001). EGAE mean score in treatment-compliant patients was significantly lower at follow-up than at baseline (2.14 vs. 1.57, p<0.001, Cohen's d=0.35).The pre-post-treatment difference in EGAE mean score in non-compliant patients was not significant (1.44 vs. 1.32, p<0.102) and Cohen's d was lower (0.19) than in compliant patients. The use of EGAE to evaluate acne grade in daily clinical dermatological practice in Spanish centres has shown feasibility, high interobserver reliability, concurrent validity and sensitivity to detect treatment effects.

    We examined the possible correlation between biotypes of Propionibacterium acnes, lipase activity, and rash degree in acne patients. Among 5 P. acnes biotypes, P. acnes biotype 3 (B3) was the most common, followed by P. acnes biotypes 1, 2 and 4; P. acnes biotype 5 was not found. P. acnes B3 was isolated from more severe skin rashes than those of the other biotypes. Production of propionic acid (PA) and butyric acid (BA) by P. acnes B3 was higher than those by the other P. acnes biotypes. As the rash degree in acne patients was more severe, the production of PA and BA elevated. Although only a few P. acnes strains were examined in the present study, P. acnes B3 had the highest lipase activity and might have the greatest influence on skin rash in acne patients.

    Full Text Available In previous studies, Propionibacterium acnes was cultured from intervertebral disc tissue of ~25% of patients undergoing microdiscectomy, suggesting a possible link between chronic bacterial infection and disc degeneration. However, given the prominence of P. acnes as a skin commensal, such analyses often struggled to exclude the alternate possibility that these organisms represent perioperative microbiologic contamination. This investigation seeks to validate P. acnes prevalence in resected disc cultures, while providing microscopic evidence of P. acnes biofilm in the intervertebral discs.Specimens from 368 patients undergoing microdiscectomy for disc herniation were divided into several fragments, one being homogenized, subjected to quantitative anaerobic culture, and assessed for bacterial growth, and a second fragment frozen for additional analyses. Colonies were identified by MALDI-TOF mass spectrometry and P. acnes phylotyping was conducted by multiplex PCR. For a sub-set of specimens, bacteria localization within the disc was assessed by microscopy using confocal laser scanning and FISH.Bacteria were cultured from 162 discs (44%, including 119 cases (32.3% with P. acnes.

    Importance Acne vulgaris is the most common skin condition affecting late adolescents across the globe. Although prior studies have evaluated epidemiologic patterns of acne vulgaris in various ethnicities and regions, adequate understanding of the worldwide burden of the disease associated with patients in their late adolescence (15–19-year olds) remains lacking. Objective To assess the global burden of the disease associated with acne vulgaris for late adolescents (15–19-year olds) and provide an overview of the epidemiology, pathophysiology, and treatment options for acne in this population. Design Database summary study. Setting Global Burden of Disease Study 2010 database. Participants Global Burden of Disease regions comprised countries with prevalence of acne vulgaris between the ages of 15 and 19 years. Main outcomes and measures Geographic region-level disability-adjusted life year rates (per 100,000 persons) associated with acne vulgaris in years 1990 through 2010. Median percentage change in disability-adjusted life year rates was estimated for each region across the specified study period. Conclusion and relevance Acne vulgaris-associated disease burden exhibits global distribution and has continued to grow in prevalence over time within this population. This continued growth suggests an unmet dermatologic need worldwide for this disorder and potential opportunities for improved access and delivery of dermatologic care. Our analysis of the literature reveals numerous opportunities for enhanced patient care. To that end, we highlight some of the effective and promising treatments currently available and address important factors, such as sex, nationality, genetics, pathophysiology, and diet, as they relate to acne vulgaris in late adolescence.

    Acne vulgaris is a chronic inflammatory disease that affects the pilosebaceous unit. Recent studies have shown an increasing number of cases of acne in adult women. These cases are predominantly normoandrogenic and have show some clinical differences compared to adolescent acne. In addition to the physical aspects, acne has a strong psychosocial impact and can lead to the onset of signs and symptoms of depression, such as anger. Our objective was to evaluate the effect on acne-specific quality of life in adult women treated with topical azelaic acid versus a combined oral contraceptive. The study population consisted of 38 adult women with acne and without any features of hyperandrogenism recruited from the clinic of Dermatology Hospital Division of São Paulo, Federal University of São Paulo from January 2012 to September 2014. Patients were randomized into two different groups: one receiving containing 20 ug of ethinylestradiol and 3 mg drospirenone in a regimen of 24 days of medication, a combined oral contraceptive (COC), and the other group topical 15% azelaic acid (AA) gel, twice daily, both for six months. The quality of life was evaluated at baseline and end of treatment with an acne specific measure (Acne-QoL). Before treatment, our data revealed a significant impact of the presence of acne on quality of life. Both treatments resulted in improvement with significant statistical values in quality of life scores. Comparing the four domains of Acne-QoL, patients treated with an oral contraceptive showed greater improvement in two domains (self-perception and acne symptoms) than those treated with azelaic acid.

    Mild-to-moderate acne vulgaris is treated with a range of mono- and combination therapies; however, clinical evidence is still required to optimize treatment recommendations. To compare the efficacy, tolerability and safety of a combination of benzoyl peroxide 3% and clindamycin 1% (BPO + CLN) with azelaic acid 20% (AzA) for the topical treatment of mild-to-moderate acne vulgaris. This was a randomized, assessor-blinded, parallel-group, multicentre study conducted in Germany. Patients with a confirmed diagnosis of acne vulgaris, aged 12-45 years, were randomized 1 : 1 to once-daily BPO + CLN gel or twice-daily AzA cream for up to 12 weeks. The primary endpoint was the percentage change in inflammatory lesions from baseline at Week 4. Secondary endpoints included total and inflammatory lesion counts and tolerability assessments. For selected secondary endpoints, inductive statistical analysis was performed post hoc. Patient safety was assessed by adverse event (AE) monitoring. Efficacy was assessed in the modified intent-to-treat (mITT) population [patients using ≥1 dose of study medication (ITT), plus baseline and ≥1 post-baseline lesion count (n = 215)]. There was a statistically significant difference in the primary endpoint, with a median decrease of -52.6% for BPO + CLN (n = 107) vs.-38.8% for AzA (n = 108; P = 0.0004). There was also a greater difference in secondary lesion endpoints at Week 12, with a median decrease in inflammatory lesions of -78.8% and -65.3% and total lesions of -69.0% and -53.9% with BPO + CLN and AzA, respectively (both P < 0.0001). Tolerability was acceptable for both treatments. Overall, 55.6% (BPO + CLN) and 69.7% (AzA) of patients reported treatment-emergent AEs, and 15.7% and 35.8% of patients experienced application site reactions with BPO + CLN (24 events; 17 patients) and AzA (60 events; 39 patients) treatment, respectively (ITT population). BPO + CLN demonstrated greater efficacy than AzA in the treatment of mild

    Several studies have reported an increase in the prevalence of adult female acne. This subtype of acne presents particular characteristics, and can be triggered by several factors such as smoking, stress, the use of oily cosmetics and even by poor sleep. Sleep quality is related to well-being and the maintenance of body homeostasis. In addition, several skin diseases present a bidirectional relationship with sleep, demonstrating an important connection between skin and the central nervous system. With this in mind, we aimed to compare the effect of two types of treatment for adult female acne (azelaic acid or a combined oral contraceptive) on sleep quality and on concentrations of stress hormones. Also, we proposed to assess the correlation of sleep and hormonal parameters with acne severity. In order to do this, 32 women underwent a clinical evaluation, completed the Pittsburgh Sleep Quality Index (PSQI) questionnaire and had their blood collected for hormone assays. These procedures were performed at baseline and after 6 months of treatment. At baseline there were no differences between the groups in terms of body mass index, age, acne severity and hormone concentrations. Results showed that both treatments demonstrated effectiveness but that women treated with azelaic acid presented a better sleep quality after the treatment compared to baseline and to the group treated with the combined oral contraceptive. The combined oral contraceptive group presented an increase in cortisol and a decrease in free testosterone concentration in relation to baseline. These data suggest that both azelaic acid and combined oral contraceptive are effective in the treatment of adult female acne but, azelaic acid seems to be a more suitable option for those women who may benefit from a better subjective sleep quality.

    Full Text Available Propionibacterium acnes, plays an important role in acne vulgaris and other diseases. However, understanding of the exact mechanisms of P. acnes pathogenesis is limited. Few studies have investigated its proteome, which is essential for vaccine development. Here, we comprehensively investigate the proteome of P. acnes strain ATCC 6919, including secreted, cell wall, membrane, and cytosolic fractions in three types of growth media. A total of 531 proteins were quantified using an Orbitrap mass spectrometer and bioinformatically categorized for localization and function. Several, including PPA1939, a highly expressed surface and secreted protein, were identified as potential vaccine candidates.

    To understand the influential factors for depression in patients with facial acne vulgaris and to provide scientific evidence for a comprehensive and systematic treatment for acne vulgaris.
 A total of 287 outpatients with facial acne vulgaris, who visited the dermatology of the Third Xiangya Hospital, were surveyed by Beck Depression Inventory (BDI). The data was collected by Epidata software (version 3.1) and processed by SPSS software package (version 18.0). The influential factors for the depression of outpatients with facial acne vulgaris were analyzed by multinomial logistic regression.
 A total of 181 patients with facial acne vulgaris showed various degrees of depression (BDI score≥5) and the rate was 63.1%. The symptoms for depression included sad and pessimistic attitude as well as the decreased attention to others (social withdrawal). The influential factors for mild, moderate or severe depression were gender, the degree and the course of acne. Female patients were more likely to suffer mild, moderate or severe depression (OR=3.62, 2.63, respectively); the risk of depression in acne patients was increased with the increase in degree of the severity (OR=2.31, 4.51, respectively); the patients with the acne course more than a year were more likely to show mild depression than those with a course less than a year (OR=4.30, 7.44, respectively). The patients with acne course more than 3 years were more likely to show moderate or severe depression compared to those with a course less than a year (OR=3.60).
 Most of facial acne patients show a different degree of depression. The acne course is longer in female patients. The more severe the acne vulgaris is, the more suffering of the depression is. Psychological care should be considered to improve the treatment and quality of life.

    Propionibacterium acnes colonizes the lipid-rich sebaceous glands of the skin. This preferential anaerobic bacterium is easily identified if cultures are prolonged. It is involved in the inflammation process of acne, but until recently, it was neglected in other clinical presentations. Despite a reported low virulence, the new genomic, transcriptomic, and phylogenetic studies have allowed better understanding of this pathogen's importance that causes many chronic and recurrent infections, including orthopedic and cardiac prosthetic, and breast or eye implant-infections. These infections, facilitated by the ability of P. acnes to produce a biofilm, require using anti-biofilm active antibiotics such as rifampicin. The antibiogram of P. acnes is not systematically performed in microbiology laboratories because of its susceptibility to a wide range of antibiotics. However, in the last 10 years, the rate of antibiotic-resistant bacteria has increased, especially for macrolides and tetracyclines. Recently, rpoB gene mutations conferring resistance to rifampicin have been also reported. Thus in case of a biofilm growth mode, the therapeutic strategy should be discussed, according to the resistance phylotype and phenotype so as to optimize the treatment of these severe infections.

    Full Text Available Acne is a chronic inflammatory disorder of the pilosebaceal unit. Dermatological disorders are often associated with a variety of psychological problems which the patient have. Psichodermatologic disorders (acne are associated with skin problems that are not directly connected to the mind, but that react to emotional states, such as stress. The aim of this article is to show if there is any psychological characteristic which are common for the whole group of ill-patients from acne, as well as whether there is correlation between any type of acne and psychological parameters. Own exploration consist at thirty patients with three clinical type of acne. Personality test-Kornel index were used for identification and diagnostic psychosomatic disorders. The results are: neurastenic parameters, parameters of conversion and parameters of psychopathy in different percent at both sex, and different clinical features. We show correlation united 2-6 psichosomatic disorders in male sex with softly type of acne. In female sex with any type of acne are responsible 7-12 united findings. The association of several psychosomatic factors could possibly be responsible for the onset of acne at any type.

    The diagnosis of acne is usually easy, but there are some pitfalls to be avoided. 'Keloid acne of the neck' and beard folliculitis are not acnes in the usual sense: both are inflammatory and fibrous reactions of the hair follicles and frizzy hair; no retentional lesions, blackheads and microcysts--are visible. Gram negative folliculitis classically occurs in acneic male subjects who have undergone extensive treatment with general antibiotics or local antiseptics, but 'de novo' cases do exist. On black skin, this condition is not exceptional, it occurs in both sexes and usually takes the nodular form. The diagnosis should be considered if there is any aggravation of acne which is resistant to classic treatment, with painful nodules on the cheeks. Treatment is based on appropriate antibiotherapy for several weeks and possibly, in a second phase, on Isotretinoin. Pityrosporum folliculitis occurs mainly on the trunk. More frequent in men than in women, it is chiefly observed in subjects living in a hot, humid climate. Demodicidosis is manifested by outbreaks of papular or papulopustular lesions of the face. On black skin the principal differential diagnosis is acne. The presence of numerous parasites is necessary for diagnosis. Clinically speaking, an important sign is when the eyelids are affected. Ivermectin is effective. Acneiform dermatitis may be induced by depigmenting preparations containing powerful dermocorticoids. It is therefore important, in cases of very inflammatory acne, to look for the other clinical signs of voluntary depigmentation. In countries where it is endemic, lepromatous leprosy should be considered. Other common dermatitis may simulate acne or else be associated with it, such as eruptive hidradenoma or molluscum contagiosum. Analysis of the different elementary lesions and the absence of retentional lesions generally enable a diagnosis to be established. © 2012 The International Society of Dermatology.

    Full Text Available A new green micellar liquid chromatographic method was developed and validated for the quantitative estimation of nicotinamide (NICO and clindamycin phosphate (CLD in bulk and pharmaceutical gel formulation. The analytes are well resolved in less than 6.0 minutes using micellar mobile phase consisting of 0.10M sodium dodecyl sulfate (SDS, 0.3% triethylamine, and 10% 2-propanol in 0.02M orthophosphoric acid at pH 3.0, running through an Eclipse XDB-C8 column (150 mm×4.6 mm, 5 μm particle size with flow rate 1.0 mL/min. The effluent was monitored with diode array detection at 210 nm. The retention times of NICO and CLD were 3.8 minutes and 5.6 minutes, respectively. The method was validated according to the International Conference on Harmonisation (ICH guidelines in terms of linearity, limit of detection, limit of quantification, accuracy, precision, robustness, and specificity to prove its reliability. Linear correlation was achieved by plotting the peak area of each drug against its concentration. It was found to be rectilinear in the ranges of 1.0–40.0 μg/mL and 0.5–15.0 μg/mL with limits of detection of 0.06 μg/mL and 0.03 μg/mL and limits of quantification of 0.19 μg/mL and 0.09 μg/mL for NICO and CLD, respectively. The method was successfully implemented for the simultaneous determination of the analytes in their bulk powder and combined gel formulation with high % recoveries. The ease of sample treatment facilitates and greatly expedites the treatment with reduced cost and improved accuracy of the procedure.

    Propionibacterium acnes have been recognized as one of the main causative agents in pathogenesis of acne. Twenty one isolates of P. acnes isolated from acne lesions were screened for lipase and protease activity which are reported to be associated in acne and inflammation. Interestingly, all P. acnes isolates demonstrated lipase activity. Similarly, 90% of test P. acnes produced protease enzyme. Antibacterial activity of the ethanol extract of Rhodomyrtus tomentosa (Aiton) Hassk. leaves and rhodomyrtone, its principle compound were tested against P. acnes using broth macrodilution method. The MIC(90) values of the ethanol extract and rhodomyrtone were 32 and 0.5 μg/mL, respectively. The numbers of the bacterial cells were reduced at least 99% after treatment with the ethanol extract and rhodomyrtone within 72 and 24 h, respectively. Cytotoxicity test of the extract and rhodomyrtone was performed on human normal fibroblast. The IC(50) values of the ethanol extract and rhodomyrtone were 476 and more than 200 μg/mL, approximately 15 and 400 folds higher than the MIC(90) values indicating that both substances were very low cytotoxic which could be applied as topical therapeutic anti-acne agents.

    Due to increasing interest from acne patients concerned about the side effects associated with conventional therapies, complementary and alternative medicine (CAM) has been suggested as a new therapeutic modality for acne vulgaris. Herbal medicine is one of these CAM treatments. Cheongsangbangpoong-tang (CBT) is a common herbal formula used in patients with acne vulgaris in the clinical practice of Korean Medicine (KM). However, despite the common use of CBT in clinical practice, the current level of evidence is insufficient to support an inhibitory effect of CBT on inflammatory acne lesions and facial heat. Therefore, this study was designed to assess the inhibitory effect of CBT on both inflammatory acne lesions and facial heat. A randomized, double-blind, parallel-group, and placebo-controlled trial will be conducted. Fifty-six participants with acne vulgaris will be randomized into one of two groups: the CBT or placebo groups. After randomization, participants will be prescribed either CBT or placebo three times a day at a dose of 5 g after meals for 8 weeks. The following outcome measurements will be used in the examination of subjects: the mean percentage change and the count change of the inflammatory and non-inflammatory acne lesions, the temperature of facial points on digital infrared thermal imaging (DITI), serum cortisol, serum dehydroepiandrosterone-sulfate (DHEA-S), visual analogue scale (VAS), investigator global assessment (IGA), and severity score on the Korean Acne Grading System (KAGS) from baseline to the end of the trial. This trial will provide evidence regarding the inhibitory effect of CBT on inflammatory acne lesions and facial heat. The findings of this trial may have important implications for the more widespread use of CBT for the treatment of acne vulgaris. The trial is registered with the Clinical Research Information Service (CRiS), Republic of Korea: KCT0001468 .

    Blue light is effective for acne treatment, inducing photodynamic destruction of Propionibacterium acnes (P. acnes). This study was designed to investigate the efficacy of combined blue and red light-emitting diode (LED) phototherapy for acne vulgaris. Twenty-four patients with mild to moderately severe facial acne were treated with quasimonochromatic LED devices, alternating blue (415 nm) and red (633 nm) light. The treatment was performed twice a week for 4 weeks. Objective assays of the skin condition were carried out before and after treatment at each treatment session. Clinical assessments were conducted before treatment, after the 2nd, 4th, and 6th treatment sessions and at 2, 4, and 8 weeks after the final treatment by grading and lesion counting. The final mean percentage improvements in non-inflammatory and inflammatory lesions were 34.28% and 77.93%, respectively. Instrumental measurements indicated that the melanin levels significantly decreased after treatment. Brightened skin tone and improved skin texture were spontaneously reported by 14 patients. Blue and red light combination LED phototherapy is an effective, safe and non-painful treatment for mild to moderately severe acne vulgaris, particularly for papulopustular acne lesions.

    There are only a few studies about epidemiological features of acne vulgaris in the literature. The aim of this study was to analyze demographic, clinical, familial and environmental characteristics of acne, the role of diet and aggravating factors and association of these factors with acne severity. Patients with a diagnosis of mild-moderate to severe acne were consecutively interviewed at the participating centers during the study period. A total of 3826 patients and 759 control patients were involved in this study. Mild acne was the most common type of acne, and most of the lesions were localized on face followed by the trunk. The severity of acne was worse in patients who had a positive family history of acne. The most common triggering factor was psychological stress. We found a positive correlation with chocolate, bread, green tea, milk, white sugar, ripe banana, ice cream, apple, orange, and red meat consumption. As we compare the acne severity according to geographical features we detected mildmoderate acne was more common in Mediterrenean region and severe acne was more common in East Anatolian region. Family history positivity was more common in Aegean region and least common in Middle Anatolian region. There was statistically significant relationship as we compare acne severity and dietary factors such as chocolate, dairy products such as milk, sunflower seed consumption within the geographical regions. This study presents the demographic and clinical characteristics of acne patients in Asian and the European parts of Turkey. We believe that this study will provide a useful overview of acne in Turkey.

    Hyaluronic acid (HA) and other glycosaminoglycans are extracellular matrix components in the human epidermis and dermis. One of the most prevalent skin microorganisms, Propionibacterium acnes, possesses HA-degrading activity, possibly conferred by the enzyme hyaluronate lyase (HYL). In this study......, we identified the HYL of P. acnes and investigated the genotypic and phenotypic characteristics. Investigations include the generation of a P. acneshyl knockout mutant and HYL activity assays to determine the substrate range and formed products. We found that P. acnes employs two distinct variants...... of the observed differences between P. acnes phylotype IA and IB/II strains. Whereas type IA strains are primarily found on the skin surface and associated with acne vulgaris, type IB/II strains are more often associated with soft and deep tissue infections, which would require elaborate tissue invasion...

    Isotretinoin is commonly used in the treatment of acne vulgaris. While one of the more common side-effects is cheilitis, we have observed an increased incidence of cheilitis prior to the commencement of systemic isotretinoin. The aim of this study was to assess the prevalence of cheilitis among acne vulgaris patients. A non-interventional cross-sectional study of patients with acne vulgaris. Patients with previous use of systemic retinoids were excluded. The patients were examined for signs and symptoms of cheilitis. Of a total of 400 patients, 134 (34%) had evidence of cheilitis at initial presentation. Two-thirds (63%) were female (P acne excorie, compared with only 8% of patients with no signs of cheilitis. Our findings suggest that cheilitis is quite common among acne vulgaris patients even before treatment with isotretinoin. © 2016 The Australasian College of Dermatologists.

    Full Text Available Background: Autologous platelet-rich plasma has recently attracted significant attention throughout the medical field for its wound-healing ability. Aims: This study was conducted to investigate the potential of platelet-rich plasma combined with fractional laser therapy in the treatment of acne scarring. Methods: Sixteen patients (12 women and 4 men who underwent split-face therapy were analyzed in this study. They received ablative fractional carbon dioxide laser combined with intradermal platelet-rich plasma treatment on one half of their face and ablative fractional carbon dioxide laser with intradermal normal saline on the other half. The injections were administered immediately after laser therapy. The treatment sessions were repeated after an interval of one month. The clinical response was assessed based on patient satisfaction and the objective evaluation of serial photographs by two blinded dermatologists at baseline, 1 month after the first treatment session and 4 months after the second. The adverse effects including erythema and edema were scored by participants on days 0, 2, 4, 6, 8, 15 and 30 after each session. Results: Overall clinical improvement of acne scars was higher on the platelet-rich plasma-fractional carbon dioxide laser treated side but the difference was not statistically significant either 1 month after the first treatment session (P = 0.15 or 4 months after the second (P = 0.23. In addition, adverse effects (erythema and edema on the platelet-rich plasma-fractional carbon dioxide laser-treated side were more severe and of longer duration. Limitations: Small sample size, absence of all skin phototypes within the study group and lack of objective methods for the evaluation of response to treatment and adverse effects were the limitations. Conclusion: This study demonstrated that adding platelet-rich plasma to fractional carbon dioxide laser treatment did not produce any statistically significant synergistic effects

    Benzoyl peroxide (BPO) was introduced in the treatment of acne in 1934. Despite the fact that only few randomized trials have been published, BPO is considered the standard in topical acne treatment. Anaerobic bacteria are reduced by oxidative mechanisms and the induction of resistant strains is reduced. Topical formulations are available at concentrations of 2.5, 5, 10 and 20 %. The effect is dose-dependent, but the irritation increases with higher concentrations. Usually 5 % BPO is sufficient to control acne grade I-II. Due to its strong oxidative potential, patients should be advised that BPO may bleach colored and dark clothing, bedding and even hair. BPO is safe for use in pregnant and lactating females because it is degraded to benzoic acid. It is a cost-effective treatment for acne grade I-II. Patients with papulopustular acne grade I-II, particularly with marked inflammation, show satisfactory improvement with topical antibiotic treatment. The following compounds are available and effective: erythromycin, clindamycin and tetracycline (the latter being less frequently used). A review in 1990 suggested that topical tetracycline was ineffective in the treatment of acne. Along with eliminating Propionibacterium acnes, the main mechanism of topical antibiotics is their antiinflammatory effect. All three penetrate the epidermal barrier well and are similarly efficacious. Randomized trials have shown that in concentrations of 2-4 %, their effects are comparable to oral tetracycline and minocycline. Combination therapy with retinoids or benzoyl peroxide (BPO) increases efficacy. Retinoids increase penetration and reduce comedones, while topical antibiotics primarily address inflammation. One side effect of topical antibacterial treatment is an increase in drug-resistant resident skin flora with gram-negative microorganisms prevailing, which can lead to gram-negative folliculitis. All three antibiotics fluoresce under black light which may produce interesting

    A multitude of options are traditionally used for the treatment of acne scars; however, newer treatment modalities are emerging to decrease the propensity for post-inflammatory hyperpigmentation and upregulate new collagen production. The aim of this study was to evaluate the efficacy of nanofat and platelet-rich plasma (PRP) infiltration alone and combined with fractional CO 2 laser resurfacing to improve atrophic scars of the face. From March 2014 to June 2015, 30 patients with atrophic acne scars on the cheeks were selected for this study. Patients were evaluated pre- and postoperatively by physical examination, photographs and ultrasound with a 22-MHz probe to measure subcutaneous tissue thickness. All patients were treated with infiltration of nanofat plus PRP. The production of PRP was achieved using the RegenLab THT tube ® method. In 15 randomly chosen patients, a fractional CO 2 laser resurfacing at 15 W was also performed right after the infiltration. An Italian version of the FACE-Q postoperative module was administered to analyze each patient's satisfaction and aesthetic perception of the result. The average preoperative thickness of subcutaneous tissue of patients from group A was 0.532 cm, while the average preoperative thickness of subcutaneous tissue of patients from group B was 0.737 cm. The average postoperative thickness of subcutaneous tissue was 1.201 cm in group A and 1.367 cm in group B. The improvement of thickness of subcutaneous tissue was 0.668 cm in group A and 0.63 cm in group B. We applied a t test on unpaired data, comparing the difference in thickness obtained with the treatment in both group A and in group B, with a p value =0.7289 (not significant). All patients in both groups had a treatment benefit, confirmed with FACE-Q postoperative module, but without a significant difference between the two groups. Subcutaneous infiltration with nanofat and PRP seems to be effective to improve atrophic scars, either alone or combined

    The classical management of acne calls for prolonged oral and/or topical treatments; however, some patients request a rapid effect to make the papules disappear within a few hours or days. To test the effect of a single overnight application of a paste containing 0.25% miconazole nitrate on acne papules, and comparison with the effect of the same but unmedicated paste. Narrow-band reflectance spectroscopy was used to assess the changes in E index (erythema) after overnight application of the pastes. In the first study, a total of 117 acne papules were assessed in 15 adolescents. Measurements of the E index were performed at 24-h intervals for 4 days on acne papules and the surrounding normal-looking skin. The last two assessments were performed the mornings preceding and following, respectively, a single application of the medicated paste. The second part of the study consisted of a double-blind, split-face study on 25 adolescents with acne. They applied each of the two formulations on a randomized part of the forehead. A total of 161 acne papules received the medicated paste and 160 received the same but unmedicated paste. Measurements were performed the mornings before and after the overnight treatment. In the first part of the study, no significant daily difference was observed between the three series of pretreatment E indices, on both acne papules and normal skin. The treatment did not affect the E index of normal skin. By contrast, it decreased significantly the E index of the acne papules. The second part of the study also showed that the medicated paste significantly decreased the E index of acne papules. This effect was significantly (P < 0.05) superior to that of the unmedicated paste. A single overnight application of miconazole nitrate paste appears to reduce the erythematous aspect of acne papules.

    The aim of this review was to evaluate, by a thorough revision of the literature, the true efficacy of currently available topic and systemic cosmetic acne agents. The efficacy of currently available cosmetic acne agents has been retrospectively evaluated via thorough revision of the literature on matched electronic databases (PubMed). All retrieved studies, either randomized clinical trials or clinical trials, controlled or uncontrolled were considered. Scientific evidence suggests that most cosmetic products for acne may enhance the clinical outcome. Cleansers should be indicated to all acne patients; those containing benzoyl peroxide or azelaic/salicylic acid/triclosan show the best efficacy profile. Sebum-controlling agents containing nicotinamide or zinc acetate may minimize excessive sebum production. Cosmetics with antimicrobial and anti-inflammatory substances such as, respectively, ethyl lactate or phytosphingosine and nicotinamide or resveratrol, may speed acne recovery. Topical corneolytics, including retinaldehyde/glycolic acid or lactic acid, induce a comedolytic effect and may also facilitate skin absorption of topical drugs. Finally, the use of specific moisturizers should be strongly recommended in all acne patients. Cosmetics, if correctly prescribed, may improve the performance of the therapy, whereas wrong procedures and/or inadequate cosmetics may worsen acne. Cosmetological recommendations may allow clinicians to make informed decisions about the role of various cosmetics and to indentify the appropriate indications and precautions. The choice of the most effective product should take into consideration the ongoing pharmacological therapy and acne type/severity as well.

    Acne vulgaris is a common dermatological disorder, one that is frequently associated with depression, anxiety and other psychological sequelae. In recent years there has been an increasing focus on the extent to which oxidative stress is involved in the pathophysiology of acne. Emerging studies have shown that patients with acne are under increased cutaneous and systemic oxidative stress. Indeed, there are indications that lipid peroxidation itself is a match that lights an inflammatory cascade in acne. The notion that lipid peroxidation is a 'starter gun' in acne is not a new one; here we review the nearly 50-year-old lipid peroxidation theory and provide a historical perspective to the contemporary investigations and clinical implications.In addition, we present a novel hypothesis in which lipid peroxidation may be priming an increased susceptibility to co-morbid depression and anxiety in those with acne. The emerging research on the systemic burden of oxidative stress in acne sheds further light on the brain-skin axis. The recent findings also suggest potential avenues of approach for the treatment of acne via specific nutrients, dietary modifications, oral and topical interventions.

    Ozenoxacin, a novel non-fluorinated topical quinolone, was assessed for in vitro antimicrobial activity against clinical isolates of propionibacteria and staphylococci according to the broth microdilution method recommended by the Clinical and Laboratory Standards Institute. The isolates used in this study were collected from Japanese patients with acne vulgaris during a period from 2012 to 2013. The MIC90s of ozenoxacin against Propionibacterium acnes (n=266), Propionibacterium granulosum (n=10), Staphylococcus aureus (n=23), Staphylococcus epidermidis (n=229) and other coagulase-negative staphylococci (n=82) were ≤0.06, ≤0.06, ≤0.06, 0.125 and ≤0.06 µg ml-1, respectively. The antimicrobial activity of ozenoxacin against the clinical isolates of propionibacteria and staphylococci was greater than that of five reference antimicrobial agents which have been used for the treatment of acne vulgaris. The MICs of ozenoxacin were correlated with those of nadifloxacin in P. acnes and S. epidermidis isolates. However, the MICs of ozenoxacin were 0.25-0.5 µg ml-1 and 0.5-8 µg ml-1 against nadifloxacin-resistant P. acnes (MIC: ≥8 µg ml-1; n=8) and S. epidermidis (MIC: ≥64 µg ml-1; n=10), respectively. These results indicated the potent antimicrobial activity against P. acnes and S. epidermidis isolates resistant to nadifloxacin. Topical ozenoxacin could represent an alternative therapeutic drug for acne vulgaris based on its potent antimicrobial activity against the isolates of propionibacteria and staphylococci from acne patients.

    Acne vulgaris is a common disease among people in Asia. International guidelines and treatment recommendations emphasize the central role of topical retinoids in the management of acne. However, topical retinoids remain underutilized in clinical practise, which may be in part due to fear of retinoid-associated dermatitis/lack of experience, particularly in Asian patients. There is a perception that Asian skin has a greater tendency toward sensitivity compared with Caucasian skin. In our clinical experience, topical retinoid therapy can be used with excellent effect to treat Asians with acne. This article discusses available published work regarding the use of topical retinoids in Asian populations, and presents tips for utilizing these important agents in daily practise. Optimizing use of topical retinoids may improve adherence and, in turn, therapeutic outcomes and patient satisfaction. © 2018 The Authors.

    Yashada bhasma (YB) and Tankana (TA) are well characterized minerals used in traditional medicine for the treatment of various skin ailments. Yashada bhasma and TA are a unique preparation of zinc and borax, respectively. The study was conducted to evaluate the in vitro inhibitory effect of YB, TA and its combination (YBTA) on Propionibacterium acne growth and P. acne-induced inflammation. The minerals were tested for anti-P. acne activity by disc diffusion and broth microdilution methods. The effect of these minerals on P. acne induced TNF-α and IL-8 production and gene expression were studied in THP-1 cells. In vitro toxicity was tested on human keratinocytes (HaCaT) and mouse embryonic fibroblasts (NIH3T3) using MTT assay. The minimum inhibitory concentrations (MIC values) for YB, TA and YBTA against P. acne were 0.1 ± 0.2, 1.9 ± 0.5 and 0.3 ± 0.5 mg mL(-1) , respectively. YB, TA and YBTA inhibited TNFα by 57.57%, 59.09% and 68.93% and IL-8 production by 48.76%, 47.92% and 51.13% in P. acne-stimulated THP-1 cells, respectively. The CTC50 values on HaCaT and NIH3T3 was 17.44 ± 0.5 and 16.37 ± 0.2 μg mL(-1) for YB, 1023.03 ± 4.0 and 1286.17 ± 4.4 μg mL(-1) for TA and 89.12 ± 2.3 and 111.58 ± 3.5 μg mL(-1) for YBTA, respectively. The present study revealed the inhibitory effect of YB, TA and YBTA on P. acne growth and inflammation. Clinical studies have suggested the anti-acne benefits of formulations containing YB and TA. The findings obtained from the present in vitro studies provide evidence to support the mechanism of anti-acne properties of YB and TA. © 2014 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    Treatment of the severe forms of acne vulgaris remains a challenge. Isotretinoin is a drug often used in these cases. Retinoids affect the mechanisms that play a role in the pathogenesis of acne, reduce the production of sebum and sizes of the sebaceous glands. However, isotretinoin appears to have undesirable side effects in the skin, mucous membranes and hair. THE AIM OF THIS STUDY WAS TO ASSESS THE EFFECT OF ACNE VULGARIS TREATMENT WITH ISOTRETINOIN ON BIOPHYSICAL SKIN PARAMETERS: skin sebum and stratum corneum hydration levels, transepidermal water loss values, pH, erythema and hair growth parameters: total number, density and proportion of anagen hair. THE STUDY INCLUDED THIRTY PATIENTS WITH ACNE TYPES: papulopustular, conglobata and phlegmonosa. Patients were treated with isotretinoin at a dose of 0.5-1.0 mg/kg/day for a period of 4-7 months. The measurements of skin biophysical parameters were performed before and after the treatment using Sebumeter SM815, Corneometer CM825, Tewameter TM300, MX Mexameter MX18 and Skin-pH-Meter PH908. Hair growth parameters were evaluated with FotoFinder Dermoscope using the TrichoScan Professional V3.0.8.76 software. The results of biophysical skin parameter measurements after the treatment showed a reduction in the severity of seborrhea. However, the skin was dry, which confirmed a lowered degree of stratum corneum hydration and an increase in transepidermal water loss values. Moreover, severity of erythema, an increase in pH value, and variations in selected hair growth parameters: decrease in total count, density and proportion of anagen hair were demonstrated. The reduction in the skin sebum levels was observed after the treatment. There was dryness of the skin, which was confirmed by biophysical skin parameter measurements. Changes in the hair growth parameters showed telogen effluvium hair loss.

Efficacy variables included DLQI and acne severity on the face, chest, and back using the Investigator's Global Assessment (IGA) scale (grade 1 = nearly clear skin; 2 = mild acne; 3 = moderate acne). Visits were scheduled at baseline, at 4-8 weeks, and at twelve weeks. Of the 251 women enrolled, 59 % had grade 1 acne at baseline; 31 %, grade 2; and 10 %, grade 3; the most commonly affected area of the body was the face (IGA grades 2 or 3: 79 %). After twelve weeks, there was significant improvement of acne on the face (IGA grades 0 or 1: 82 %), chest, and back. Median DLQI decreased from nine at baseline to five after twelve weeks. Ninety percent of physicians and patients rated the tolerability of the treatment as very good or good. Treatment with azelaic acid 20 % cream significantly improves acne severity and disease-related QoL in adult women. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    Acne vulgaris affects as much as 80% of the adolescent population and persists in approximately 3% of middle-aged adults. Only a percentage of these persons seek medical help, however, acne can cause levels of anxiety and depression akin to a chronic illness. A recurring question from patients who seek help from various healthcare professionals - their pharmacist, family doctor or dermatologist, is "why?" They also ask questions about a possible familial link, the impact of their diet and the association with their hormones. The following review aims to link these factors with the end result - inflammation.

    Acne presenting in adult women is commonly encountered in clinical practice. Many affected women have had acne during their teenaged years, have tried several therapies in the past, and are seeking effective treatment. Others are frustrated by the inexplicable emergence of acne as an adult when they never had it as a teenager. Both groups seek an explanation of why they have acne, are often psychosocially affected by its effects on appearance and self-esteem, and all are wanting effective and safe treatment. Clinicians are encouraged to connect favorably with each patient through careful history and physical examination and to consider underlying causes of androgen excess. Practical approaches to examination and laboratory evaluation are discussed.

Although prior studies have evaluated epidemiologic patterns of acne vulgaris in various ethnicities and regions, adequate understanding of the worldwide burden of the disease associated with patients in their late adolescence (15–19-year olds remains lacking. Objective: To assess the global burden of the disease associated with acne vulgaris for late adolescents (15–19-year olds and provide an overview of the epidemiology, pathophysiology, and treatment options for acne in this population. Design: Database summary study. Setting: Global Burden of Disease Study 2010 database. Participants: Global Burden of Disease regions comprised countries with prevalence of acne vulgaris between the ages of 15 and 19 years. Main outcomes and measures: Geographic region-level disability-adjusted life year rates (per 100,000 persons associated with acne vulgaris in years 1990 through 2010. Median percentage change in disability-adjusted life year rates was estimated for each region across the specified study period. Conclusion and relevance: Acne vulgaris-associated disease burden exhibits global distribution and has continued to grow in prevalence over time within this population. This continued growth suggests an unmet dermatologic need worldwide for this disorder and potential opportunities for improved access and delivery of dermatologic care.

    To assess the cost-effectiveness from the payer perspective of using dermatologists versus pediatricians to treat acne in adolescents ages 10-18. A Markov model was constructed to explore outcomes over a 2-year period from the US private payer perspective. Patients ages 10-18 with acne entered the model under the "dermatologist"and "pediatrician" conditions. In each 3-month cycle,each modeled patient received topical retinoids,benzoyl peroxide (BP), antibiotics, or no treatment,and could progress to an acne-free state or remain in an acne state. The average patient spent42.3% of the time in acne-free states under the dermatologist condition and 28.0% of the time in acne-free states under the pediatrician condition.The cohort of 1000 patients experienced 1900 total quality-adjusted life years (QALYs) at a cost of $2.33 million in the dermatologist condition and 1883 total QALYs at a cost of $1.62 million in the pediatrician condition, yielding an ICER of $40,000/QALY. Most sensitivity analyses confirmed the base case results. Dermatologist treatment appears cost-effective related to producing additional QALYs at a cost of less than $100,000 per QALY gained. Health plans should consider creating incentives to direct enrollees to dermatologists for acne treatment.

    Intervertebral disc with Propionibacterium acnes (P. acnes) is suggested to be an etiology of Modic type I changes in the adjacent bone marrow. However it is unknown if disc cells can respond to P. acnes and if bone marrow cells respond to bacterial and disc metabolites draining from infected discs. Human disc cells (n = 10) were co-cultured with 10- and 100-fold excess of P. acnes over disc cells for 3 h and 24 h. Lipopolysaccharide was used as positive control. Expression of IL1, IL6, IL8, and CCL2 by disc cells was quantified by quantitative PCR. Lipase activity was measured in culture supernatants (n = 6). Human vertebral bone marrow mononuclear cells (BMNCs) (n = 2) were cultured in conditioned media from disc cell/P. acnes co-cultures and expression of IL1, IL6, IL8, and CCL2 was measured after 24 h. All disc cells responded to lipopolysaccharide but only 6/10 responded to P. acnes with increased cytokine expression. Cytokine increase was time- but not P. acnes concentration-dependent. Disc cell responsiveness was associated with the presence of lumbar Modic changes in the donor. Lipase activity was increased independent of disc cell responsiveness. BMNCs responded with inflammatory activity only when cultured in supernatants from responsive disc cell lines. Disc cell responsiveness to P. acnes associates with the presence of lumbar Modic changes. Furthermore, bone marrow cells had an inflammatory response to the cocktail of disc cytokines and P. acnes metabolites. These data indicate that low virulent P. acnes infection of the disc is a potential exacerbating factor to Modic changes.

    Full Text Available Objective: The purpose of this study was to assess the impact of acne on the quality of life. Its secondary objective was to assess the influence of gender of students and severity of symptoms on the quality of life.  Methods: A cross sectional study was conducted on 100 students at Sultan Qaboos University (SQU (40 males and 60 females diagnosed with acne who attended the Student Clinic during a period of three months from September to December 2009. The Acne Quality Of Life index (Acne-QoL questionnaire was used to assess the patient’s quality of life in four different domains: self-perception, social, emotional, and acne symptoms.  Results: Acne affected all areas of the patients, quality of life with the emotional domain found to be the most affected. Overall, female patients reported more adverse QoL effects. The mean score for self-perception for female students was 2.5 and 2.8 for males (p=0.300. The role-social domain approached a significant difference between genders (p=0.078. There was a statistically significant correlation between severity of acne symptoms and the other three domains. The correlation was highest between acne symptoms score and self-perception score.  Conclusion: This study showed that acne affects the quality of life of affected SQU students treated by primary care physicians at the Student Clinic. Therefore, physicians should take into account the effect of acne on the persons’ quality of life when individualizing treatment.

A bakuchiol, Ginkgo biloba extract, and mannitol (BGM complex has been developed to provide patients with acne with a specific dermocosmetic to be used adjunctively with conventional treatments. Objective: The aim of these studies was to assess the antibacterial, anti-inflammatory, and antioxidative potential of BGM complex and its individual compounds as well as its impact on sebum composition. Methods: The antibacterial, anti-inflammatory, and antioxidative potential of BGM complex and its compounds was assessed through in vitro, ex vivo, and clinical studies. The clinical benefit of BGM complex formulated in a cream was assessed in subjects prone to acne through sebum composition analysis and photometric assessments. Results: Results from the studies showed that the BGM complex has significant antibacterial, anti-inflammatory, and antioxidative properties. At similar concentrations, bakuchiol has up to twice the antioxidative potential than vitamin E. In subjects, BGM complex regulated the sebum composition in acne patients by increasing the level of sapienic and linolenic acid and reducing the level of oleic acid. The reduced number of porphyrins on the skin surface showed that it is also effective against P. acnes. Conclusion: BGM complex provides a complete adjunctive care in patients with acne by targeting etiopathogenic factors of acne: dysseborrhea, inflammation, and P. acnes proliferation.

    Full Text Available Background: Acne vulgaris is a common disease among adolescent. There is paucity of information on knowledge and understanding of acne patients about their condition. Objective: This study was carried out to evaluate beliefs and perception of acne patient toward their understanding of disease, treatment option, and information source. Materials and Methods: A cross-sectional study was conducted on acne patients by means of a questionnaire during 2013–2014 at MMIMSR, Ambala. An adapted version of questionnaire of Brigitte et al. was used and was modified to suit Indian sentiments. Results: A total of 200 acne patients were participated in the study. Mean age of participants was 19.80 years. Male:female ratio was 2:1. Causes implicated were diet (85%, puberty (65%, and mood swings (46%. Fatty food and stress were most common agents held responsible for acne flaring. Popular sources of information were friends and parents. 102 patients had used steroids one way or the other. Acne was considered curable by 65% with an anticipated duration of treatment lasting up to 12 months. Conclusion: Misconceptions are widespread among the population. A health education program is needed which should be included in school curriculum to improve their understanding of the condition.

    In acne vulgaris, antimicrobial peptides (AMPs) could play a dual role; i.e., protective by acting against Propionibacterium acnes, pro-inflammatory by acting as signalling molecules. The cutaneous expression of 15 different AMPs was investigated in acne patients; furthermore, the impact of isotretinoin therapy on AMP expression was analysed in skin biopsies from 13 patients with acne vulgaris taken before, during and after a 6-month treatment cycle with isotretinoin using quantitative real-time polymerase chain reaction. Cutaneous expression of the AMPs cathelicidin, human β-defensin-2 (HBD-2), lactoferrin, lysozyme, psoriasin (S100A7), koebnerisin (S100A15), and RNase 7 was upregulated in untreated acne vulgaris, whereas α-defensin-1 (HNP-1) was downregulated compared to controls. While relative expression levels of cathelicidin, HBD-2, lactoferrin, psoriasin (S100A7), and koebnerisin (S100A15) decreased during isotretinoin treatment, only those of cathelicidin and koebnerisin returned to normal after 6 months of isotretinoin therapy. The increased expression of lysozyme and RNase 7 remained unaffected by isotretinoin treatment. The levels of granulysin, RANTES (CCL5), perforin, CXCL9, substance P, chromogranin B, and dermcidin were not regulated in untreated acne patients and isotretinoin had no effect on these AMPs. In conclusion, the expression of various AMPs is altered in acne vulgaris. Isotretinoin therapy normalizes the cutaneous production of distinct AMPs while the expression of others is still increased in healing acne. Considering the antimicrobial and pro-inflammatory role of AMPs, these molecules could serve as specific targets for acne therapy and maintenance of clinical remission.

    Full Text Available The object of this study was to discover an alternative therapeutic agent with fewer side effects against acne vulgaris, one of the most common skin diseases. Acne vulgaris is often associated with acne-related bacteria such as Propionibacterium acnes, Staphylococcus epidermidis, Staphylococcus aureus, and Pseudomonas aeruginosa. Some of these bacteria exhibit a resistance against commercial antibiotics that have been used in the treatment of acne vulgaris (tetracycline, erythromycin, and lincomycin. In the current study, we tested in vitro antibacterial effect of chitosan-phytochemical conjugates on acne-related bacteria. Three chitosan-phytochemical conjugates used in this study exhibited stronger antibacterial activity than that of chitosan (unmodified control. Chitosan-caffeic acid conjugate (CCA showed the highest antibacterial effect on acne-related bacteria along with minimum inhibitory concentration (MIC; 8 to 256 μg/mL. Additionally, the MIC values of antibiotics against antibiotic-resistant P. acnes and P. aeruginosa strains were dramatically reduced in combination with CCA, suggesting that CCA would restore the antibacterial activity of the antibiotics. The analysis of fractional inhibitory concentration (FIC indices clearly revealed a synergistic antibacterial effect of CCA with antibiotics. Thus, the median sum of FIC (∑FIC values against the antibiotic-resistant bacterial strains ranged from 0.375 to 0.533 in the combination mode of CCA and antibiotics. The results of the present study suggested a potential possibility of chitosan-phytochemical conjugates in the control of infections related to acne vulgaris.

    Background: Oral isotretinoin is highly effective in all forms and grades of acne, even in lower dosages (acne vulgaris. Materials and Methods: A total of 240 patients with moderate to severe acne vulgaris were selected and randomized into two groups and treated with a fixed dose of 20 mg of isotretinoin (Group A - daily and Group B - alternate days) for 24 weeks and followed up for 12 weeks post therapy. Results: A total of 234 patients completed the study. At the end of therapy, decrease in the total acne loads up to 98.99% (Group A) and 97.69% (Group B) was achieved from the baseline (P acne, Group A performed significantly better than Group B until the end of 36 weeks. While in the moderate acne, significant difference in the response between both groups was observed only up to 12 weeks. No serious side effect was observed. Conclusion: Both isotretinoin regimens were well tolerated and found to be an effective treatment for moderate to severe acne vulgaris. However, in moderate acne 20 mg alternate day regimen may be preferred. A 20 mg daily regimen is a better choice for severe acne in terms of response. Limitation: Small sample size and short follow-up period. PMID:27730033

    Acne is a common skin disease in society and often leads to scarring. In this paper, we demonstrate the capabilities of swept-source optical coherence tomography (SS-OCT) in detecting specific features of acne lesion initiation and scarring on human facial skin in vivo over 30 days. Optical microangiography (OMAG) technique made it possible to image 3D tissue microvasculature changes up to 1 mm depth in vivo without the need of exogenous contrast agents in ~10 seconds. The presented results show promise to facilitate clinical trials of treatment and prognosis of acne vulgaris by detecting cutaneous microvasculature and structural changes within human skin in vivo.

    This review summarizes important clinical developments in acne vulgaris identified from 17 systematic reviews published between February 2011 and August 2012. Regarding causes, Demodex mites have been shown to be associated with both acne vulgaris and rosacea, although it is unclear if their eradication improves either disease. Some weak evidence has emerged that suggests a possible link between dairy produce and acne, which warrants further research. With reference to the effects of acne, there is good evidence that acne negatively affects quality of life, self-esteem and mood in adolescents. Acne is also associated with an increased risk of anxiety, depression and suicidal ideation, highlighting the importance of asking patients with acne directly about psychological issues in order to identify those who might benefit from early psychiatric support. Regarding treatment, there seems to be no additional benefit to using higher strengths of benzoyl peroxide, and lower strengths such as 2.5% have fewer side effects. Despite earlier concerns of increased mortality in those using topical tretinoin for skin cancer prevention, a systematic review on this topic has not found any convincing evidence of a link between such non-cutaneous events and once-daily application of 0.02-0.05% tretinoin. Combined oral contraceptives are of benefit in both inflammatory and non-inflammatory acne. Current surveys suggest that implementation of the pregnancy prevention programme for isotretinoin may not be stringent, and a high level of monitoring and audit is recommended. Ablative and non-ablative laser resurfacing for the treatment of acne scars may be beneficial, but further studies with a longer follow-up period are required. © 2014 British Association of Dermatologists.

    2017-04-01

    BACKGROUND: Atrophic scarring in skin of color is a common, permanent, and distressing result of uncontrolled acne vulgaris. Ablative lasers and chemical peels are frequently used to improve the appearance of atrophic scars, primarily through the stimulation of collagen and elastin; however, these treatment modalities are associated with risks, such as dyspigmentation and hypertrophic scarring, especially in patients with darker skin. OBJECTIVE: We evaluated the efficacy of topically applied synthetic epidermal growth factor (EGF) serum in reducing the appearance of atrophic acne scars in skin of color. METHODS: A single-center clinical trial was performed on twelve healthy men and women (average age 32.5) with Fitzpatrick Type IV-V skin and evidence of facial grade II-IV atrophic acne scars. Subjects applied topical EGF serum to the full-face twice daily for 12 weeks. Scar improvement was investigated at each visit using an Investigator Global Assessment (IGA), a Goodman grade, clinical photography, and patient self-assessment. RESULTS: Eleven subjects completed the trial. Compared to baseline, there was an improvement in mean IGA score from 3.36 (SEM = 0.15) to 2.18 (SEM = 0.33). Mean Goodman grade was reduced from 2.73 (SEM = 0.19) to 2.55 (SEM = 0.21). Of the eleven pairs of before and after photographs, nine were correctly chosen as the post-treatment image by a blind investigator. On self-assessment, 81% reported a "good" to "excellent" improvement in their scars compared to baseline (P = 0.004). CONCLUSION: Topical EGF may improve the appearance of atrophic acne scars in skin of color. Additional, larger studies should be conducted to better characterize improvement.

    Propionibacterium acnes is a common cause of infection following shoulder surgery. Studies have shown that standard surgical preparation does not eradicate P acnes. The purpose of this study was to examine whether topical application of benzoyl peroxide (BPO) gel could decrease the presence of P acnes compared with today's standard treatment with chlorhexidine soap (CHS). We also investigated and compared the recolonization of the skin after surgical preparation and draping between the BPO- and CHS-treated groups. In this single-blinded nonsurgical study, 40 volunteers-24 men and 16 women-were randomized to preoperative topical treatment at home with either 5% BPO or 4% CHS on the left shoulder at the area of a deltopectoral approach. Four skin swabs from the area were taken in a standardized manner at different times: before and after topical treatment, after surgical skin preparation and sterile draping, and 120 minutes after draping. Topical treatment with BPO significantly reduced the presence of P acnes measured as the number of colony-forming units on the skin after surgical preparation. P acnes was found in 1 of 20 subjects in the BPO group and 7 of 20 in the CHS group (P = .044). The results remained after 2 hours (P = .048). Topical preparation with BPO before shoulder surgery may be effective in reducing P acnes on the skin and preventing recolonization.

    The relapses and the chronicity of acne inversa cause a significant impact on the quality of life of the affected patients and urge for a search of more effective treatments. We report the treatment of four consecutive acne inversa patients with pulse dye laser-mediated photodynamic therapy (PDL-PDT). Three months after the end of the treatment there was no improvement in comparison with opposite control sites. Intense pain during treatment was reported by all the patients. These cases do not support the use of PDL-PDT for treating acne inversa.

We aim to study the impact of post-acne scarring on the quality of life (QOL among young adults in Singapore. Settings and Design: This was a non-interventional prospective study. Materials and Methods: Patients aged 21-40 years with atrophic and hypertrophic acne scars who attended the National Skin Centre, Singapore were recruited in the study. They answered a simple questionnaire and the clinical severity of their acne scars were assessed by the doctor. Statistical Analysis Used: Descriptive analyses using absolute and percentage frequencies were performed on all data. The test of significance was two-sided and was set at 5% (P ≤ 0.05. Differential analyses were conducted using the parametric, independent two-sample t-test and non-parametric Mann-Whitney U-test. The statistical assessments were performed using SPSS version 18.0. Results: A total of 100 patients were studied. The mean patients′ subjective self-scoring on the severity of their post-acne scars was 5.78/10 and the mean Dermatology Life Quality Index (DLQI for post-acne scars was 5.61. Many (36%, n = 36 were self-conscious of their acne scars and 24%, (n = 24 felt that their acne scars was affecting their social activities. Conclusions: Our study showed that post-acne scars have a significant negative effect on the QOL of young adults. It highlights the need to increase public awareness of acne vulgaris and its sequelae through education programs and advocating early treatment to reduce the risk of scarring.

    Current treatments for acne scars and enlarged facial pores have shown limited efficacy. To evaluate the efficacy and safety of the fractional photothermolysis system (FPS) with dynamic operating mode on acne scars and enlarged pores. Twelve patients with mild to moderate atrophic acne scars and enlarged pores were included in this study. Three sessions of FPS treatment were performed for acne scars and facial pores monthly. Two blinded dermatologists who compared before and after photos based on a quartile grading scale conducted objective clinical assessments of acne scar- and facial pore-treated areas. We took a biopsy immediately after one treatment with the laser from one of the authors to assess the histologic effects of the laser on facial pores. Follow-up results at 4 months after the last treatment revealed that, of the 12 patients, for acne scars, five demonstrated clinical improvements of 51% to 75% and three demonstrated improvements of 76% to 100%, and for facial pores, five demonstrated moderate clinical improvements of 26% to 50% and three demonstrated improvements of 76% to 100%. Side effects, including pain, post-treatment erythema, and edema, were resolved within 1 week. We suggest that the FPS may provide a new treatment algorithm in some cases with acne scars and enlarged pores. Considering the lack of placebo-controlled, split-face design of our study, optimized, prospective studies should be conducted to fully assess the efficacy of FPS with dynamic operating mode.

    The anaerobic skin commensal Propionibacterium acnes is an underestimated cause of human infections and clinical conditions. Previous studies have suggested a role for the bacterium in lumbar disc herniation and infection. To further investigate this, five biopsy samples were surgically excised...... from each of 64 patients with lumbar disc herniation. P. acnes and other bacteria were detected by anaerobic culture, followed by biochemical and PCR-based identification. In total, 24/64 (38%) patients had evidence of P. acnes in their excised herniated disc tissue. Using recA and mAb typing methods...... isolate collection (63%) suggests that the role of P. acnes in lumbar disc herniation should not be readily dismissed....

    To analyze the therapeutic regularities and characteristics of blood-letting therapy for acne in the past clinical practice by using data mining. Original papers about acne treated by pricking blood therapy were searched and screened from common databases as Chinese National Knowledge Infrastructure Database (CNKI), WanFang Data, SinoMed, Ovid, ScienceDirect, Socolar, SciFinder, Foreign Medical Journal Full-Text Service (FMJS) and PubMed using keywords of acne+bleeding therapy, acne+blood-letting, acne+ pricking blood, followed by establishing a data plateform to conduct a data mining using Online Analytical Processing (OLAP). A total of 230 original journal articles about acne treated by pricking blood therapy were collected. The included acne cases with wind-heat pattern were predoment, being 56 in frequency-times and acounting for 24. 78 %. In the treatment of acne, the therapeutic tool, three-edged needle was often used, being 168 in frequency and acounting for 71.79%. The frequently employed acupoints were those of the Governor Vessel and Bladder Meridian, such as Dazhui (GV 14) and back-shu points. When auricular points used for blood-letting, Erjian (EX-HN 6) and the Vena of the auricular back were most frequently selected. In addition to blood-letting, other therapies such as Chinese herbal medicines, filiform needles, and otopoint-pellet pressure were also used in combination, being 166 in items and constituting 72. 17%. Generally, blood-letting treatment was conducted once every three days (twice a week) or once every two days (three times a week) for about 20 sessions for each acne patient. Blood-letting therapy is effective in the treatment of acne. But if used in combination with other therapies, the therapeutic effect would be better.

The aim of this study was to compare the efficacy of oral flutamide with that of a cyproterone-estradiol combination in treating acne lesions.Methods: A randomized clinical trial enrolled patients with moderate acne into two equal groups to receive either oral flutamide or the cyproterone-estradiol combination for 6 months. Lesion count, Acne Severity Index, and Global Acne Grading system (GAGS scores were used to assess improvement in acne lesions. The dichotomous measurement scale for primary endpoint assessment was defined as improvement from moderate to mild acne based on GAGS score. Patient satisfaction and dermal fat were also assessed. Intention to treat and per protocol analyses were done, reporting related effect sizes.Results: Both treatments resulted in substantial improvement in acne lesions. Although flutamide seemed to have higher efficacy, an intention to treat analysis did not find the two treatment protocols to be different. The relative risk in intention to treat analysis was 1.8 (95% confidence interval [CI] 0.89–1.6, and was 1.33 (95% CI 1.03–1.72 for the per protocol analysis. The number needed to treat for flutamide compared with the cyproterone-estradiol combination was 7.7 and 4.2 in the intention to treat and per protocol analyses, respectively.Conclusion: Flutamide appears to be more effective than a cyproterone-estradiol combination in some aspects of acne treatment, but this requires confirmation in a larger trial.Keywords: acne vulgaris, flutamide, cyproterone acetate, ethinyl estradiol, androgen antagonists

    Full Text Available The present study aimed to understand the biofilm formation mechanism of Propionibacterium acnes by analyzing the components and structure of the biofilms. P. acnes strains were isolated from the surface of explanted cardiac pacemaker devices that exhibited no clinical signs of infection. Culture tests using a simple stamp culture method (pressing pacemakers against the surface of agar plates revealed frequent P. acnes colonization on the surface of cardiac pacemaker devices. P. acnes was isolated from 7/31 devices, and the isolates were categorized by multilocus sequence typing into five different sequence types (STs: ST4 (JK18.2, ST53 (JK17.1, ST69 (JK12.2 and JK13.1, ST124 (JK5.3, ST125 (JK6.2, and unknown ST (JK19.3. An in vitro biofilm formation assay using microtiter plates demonstrated that 5/7 isolates formed biofilms. Inhibitory effects of DNase I and proteinase K on biofilm formation varied among isolates. In contrast, dispersin B showed no inhibitory activity against all isolates. Three-dimensional live/dead imaging of P. acnes biofilms with different biochemical properties using confocal laser microscopy demonstrated different distributions and proportions of living and dead cells. Additionally, it was suggested that extracellular DNA (eDNA plays a role in the formation of biofilms containing living cells. Ultrastructural analysis of P. acnes biofilms using a transmission electron microscope and atmospheric scanning electron microscope revealed leakage of cytoplasmic components along with cell lysis and fibrous structures of eDNA connecting cells. In conclusion, the biochemical properties and structures of the biofilms differed among P. acnes isolates. These findings may provide clues for establishing countermeasures against biofilm-associated infection by P. acnes.

    Acne vulgaris is a pervasive inflammatory disorder of the skin, with multiple etiologies and treatment options. Although first-line therapies exist, it is often the case that a patient will present with an underlying disorder that prohibits the use of most currently accepted treatment modalities. We present a patient with severe acne vulgaris and a history of retinitis pigmentosa who was treated with 595 nanometer pulsed dye laser therapy, in conjunction with therapeutic alternatives to first-line acne medications. Our patient exhibited a significant and sustained improvement with the combined use of 595 nanometer pulsed dye laser, Yaz (drospirenone-ethinyl estradiol), dapsone, topical metronidazole, sodium-sulfacetamide wash, and topical azelaic acid. The positive results in this case, suggest that this combined treatment modality may serve as an example of a safe and effective treatment alternative in the management of acne vulgaris complicated by medical co-morbidities that contraindicate the use of most first-line treatment options.

    Acne vulgaris is a chronic dermatologic disease with four factors involved in the development of lesions. Treatments need to address as many of these underlying factors as possible in order to reduce acne lesions. As such, purified bee venom (PBV ™ ) serum is an attractive therapeutic option for acne, but little data exist on the efficacy of this treatment strategy. In this prospective, noncomparative study, 30 subjects having mild-to-moderate acne vulgaris were enrolled and treated with PBV ™ serum twice daily for a period of 6 weeks. Clinical evaluation of lesions by expert visual grading and image analysis were made at weeks 0 (baseline), 3, and 6. The average visual acne grade of all volunteers significantly improved with the PBV ™ serum treatment at weeks 3 (P < 0.05) and 6 (P < 0.001) when compared with the baseline grade at week 0. In addition, there was a mean percent improvement of 8.6% and 52.3% in acne grade observed after 3 and 6 weeks of PBV ™ serum use, with 20% and 77% of the subjects showing improvement, respectively, when compared with baseline. Moreover, the subjects showed improvement in open comedones, closed comedones, papules, pustules, and nodules after 3 and 6 weeks of PBV ™ serum use. Six weeks of treatment with PBV ™ serum was found to be effective in the treatment of mild-to-moderate acne vulgaris, with no incidence of serious side effects or irritation. © 2016 The Authors Journal of Cosmetic Dermatology Published by Wiley Periodicals, Inc.

    Propionibacterium acnes has rarely been reported as the causative organism in acute endophthalmitis following penetrating ocular trauma. We report a 53-year-old man, who presented with best corrected vision of counting fingers at 2 m, acnes. At the fifth month follow-up, the best corrected vision had improved to 20/20, N6. Thus, a good visual outcome was achieved, following appropriate treatment of a rather unusual causative organism. PMID:24096075

    There is a potential hazard of thyroid cancer after exposure to external irradiation for the treatment of adolescent acne vulgaris. We noted a 60% incidence of thyroid carcinoma among 20 patients with such a history, who were operated on for thyroid nodules during a five-year period. Eighty-three percent of the patients with carcinoma had either a follicular or a mixed papillary-follicular carcinoma; 17% had a papillary carcinoma; 33% had regional node metastases; none had evidence of distant metastases. The interval between radiation exposure and thyroidectomy ranged from nine to 41 years. This association of thyroid neoplasms and a prior history of radiation for acne vulgaris may be coincidental and therefore remains to be proved by retrospective surveys of large numbers of treated patients with appropriate controls

    Racial health disparities are widespread in the United States, but little is known about racial disparities in the management of dermatological conditions. Nationally representative data on the management of acne vulgaris were gathered from the National Ambulatory Medical Care Survey (NAMCS) for the years 2005-2014. Visits to any specialist were included. Rao-Scott chi-square tests and multivariate adjusted logistic regressions were used to identify differences in patient demographics, visit characteristics and acne medications across races. Black patients are less likely than white patients to visit a dermatologist (adjusted odds ratio (aOR) 0.48, p = 0.001), receive any acne medication (aOR 0.64, p = 0.01), receive a combination acne medication (aOR 0.52, p = 0.007) or receive isotretinoin (aOR 0.46, p = 0.03). Adjusting for management by a dermatologist eliminated the association between race and the prescription of any acne medication as well as between race and the prescription of isotretinoin. Among outpatient visits for acne in the United States, racial disparities exist in the likelihood of seeing a dermatologist and receiving treatment. Treatment disparities are less common when care is provided by a dermatologist. More research is needed to better understand the causes of disparities in acne management and other dermatological conditions.

    2016-01-01

    Acne is a multifactorial skin disorder frequently observed during adolescence with different grades of severity. Multiple factors centering on sebum secretion are implicated in acne pathogenesis. Despite the recognized role of sebum, its compositional complexity and limited analytical approaches have hampered investigation of alterations specifically associated with acne. To examine the profiles of lipid distribution in acne sebum, 61 adolescents (29 males and 32 females) were enrolled in this study. Seventeen subjects presented no apparent clinical signs of acne. The 44 affected individuals were clinically classified as mild (13 individuals), moderate (19 individuals), and severe (12 individuals) acne. Sebum was sampled from the forehead with SebutapeTM adhesive patches. Profiles of neutral lipids were acquired with rapid-resolution reversed-phase/HPLC-TOF/MS in positive ion mode. Univariate and multivariate statistical analyses led to the identification of lipid species with significantly different levels between healthy and acne sebum. The majority of differentiating lipid species were diacylglycerols (DGs), followed by fatty acyls, sterols, and prenols. Overall, the data indicated an association between the clinical grading of acne and sebaceous lipid fingerprints and highlighted DGs as more abundant in sebum from adolescents affected with acne.

    Acne vulgaris is a chronic dermatologic problem with multiple factors involved in its pathogenesis. Alternative solutions to acne treatment were instigated by antibiotic resistance despite of its extensive use. Purified bee venom (PBV) has been proposed as a promising candidate for that purpose. The present study was designed to confirm the antibacterial effect of PBV and access the efficacy of cosmetics containing PBV in subjects with acne vulgaris. The skin bacterium Propionibacterium acnes was incubated with PBV at various concentrations and bacterial growth was evaluated using the colony forming unit (CFU) assay. The mechanism of PBV employed in killing P. acnes was examined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). In addition, a total of 12 subjects were randomized in a double-blind, controlled trial to receive either cosmetics containing PBV or cosmetics without PBV for two weeks. Evaluations included lesion counts and skin microorganism. PBV exhibited antimicrobial activity in a concentration-dependent manner, reducing the number of P. acnes CFU by approximately 6 logs at a concentration of 0.5 mg. When PBV concentration was higher than 1.0 mg, no P. acnes colonies were spotted on an agar. TEM and SEM of untreated P. acnes illustrated the normal pleomorphic structure, whereas the PBV-treated bacterium lost the integrity of surface architecture. Significant difference (P=0.027) in the grading levels based on numbers of lesion counts for inflammatory and noninflammatory was observed in favour of the PBV group compared with the control group. In terms of average decrement of skin microorganism, subjects receiving cosmetics containing PBV experienced a significant 57.5% decrease of adenosine triphosphate levels, whereas participants receiving cosmetics without PBV experienced a nonsignificant decrease of 4.7%. These results show that the in vitro actions of antimicrobial activity of PBV were translated in vivo. Cosmetics

  7. Hepatitis B, interferon, and acne fulminans in a young girl

    2016-01-01

    Full Text Available Acne fulminans (AF is a very rare severe form of acne seen in young males, characterized by a sudden and explosive onset of hemorrhagic pustules and ulceration on the trunk, systemic features in the form of fever, polyarthropathy, malaise, erythema nodosum and painful osteolytic bone involvement with leukocytosis, and an elevated erythrocyte sedimentation rate. Conventional treatment of AF includes corticosteroids or immunosuppressive agents for the initial phase followed by isotretinoin. Active hepatitis B infection with a high viral load precludes the administration of any immunosuppressive drugs. We present the case of an 18-year-old girl with a history of occasional acne who presented with AF of sudden onset following administration of interferon-alpha-2a for her recently detected hepatitis B infection. Management of hepatitis B was withheld in view of her general condition. The patient was managed with low dose isotretinoin with subsidence of lesions. AF in a young female precipitated by interferon and its management with isotretinoin in the presence of active hepatitis B infection make the case unique.

    Demodex mite density is emphasised in the aetiopathogenesis of acne rosacea. Reflectance confocal microscopy (RCM) has been shown to be a good method for determining demodex mite density. The objective was to determine demodex mite density using RCM in acne rosacea patients and compare them with controls. In all, 30 papulopustular rosacea (PPR) and 30 erythematotelangiectatic rosacea (ETR) totally 60 acne rosacea patients and 40 controls, were enrolled in the study. The right cheek was selected for imaging and RCM was used for scanning. Ten images of 1000 × 1000 μm (total 10 mm 2 ) area were scanned from adjacent areas. The numbers of follicles, infested follicles and mites were counted. The mean numbers of mites per follicle and infested follicles were calculated and compared in the patients and control groups. The mean number of mites was 44.30 ± 23.22 in PPR, 14.57 ± 15.86 in ETR and 3.55 ± 6.48 in the control group (P rosacea aetiopathogenesis.

    Acne scars are a major concerning problem to all acne patients affecting their quality of life. Platelet-rich plasma (PRP) and fractional CO 2 laser are innovative treatment modalities for acne scars. Carboxytherapy can also be used to improve scar tissue through the increase in collagen deposition and reorganization, and the improvement in skin texture and tone. The aim of this work was to compare the efficacy, safety, and complications of the intradermal injection of PRP combined with carboxytherapy and PRP combined with fractional CO 2 laser, in the treatment of atrophic acne scars. Forty patients with atrophic acne scars were divided into 2 groups. Group A included 20 patients and was subjected to three fractional CO 2 laser sessions combined with PRP injection. Group B included 20 patients and was subjected to three sessions of carboxytherapy combined with PRP injection. Both fractional CO 2 laser and carboxytherapy combined with PRP showed improvement in acne scars and patients' satisfaction but the improvement with fractional CO 2 laser was significantly better than carboxytherapy but with more side effects. Improvement of acne scars was noted in both treatment modalities with obvious higher and statistically significant results in favor of fractional CO 2 laser but with more side effects. Carboxytherapy is a promising tool in treatment of acne scars with less complication. © 2018 Wiley Periodicals, Inc.

    The isolation of Propionibacterium acnes in blood cultures is often considered a contaminant. On rare occasions, P. acnes can cause severe infections, including endocarditis and intravascular prosthesis-associated infections. To evaluate the discrimination between a contaminant and a clinically relevant infection we used an Ouchterlony test system to quantify the antibody response to P. acnes in a patient with a proven P. acnes endocarditis. We report on a 64-year-old Caucasian man who developed P. acnes endocarditis four years following a composite valve-graft conduit replacement of the aortic root. Bacterial growth in blood cultures was detected after an incubation period of 6 days. However, the antibody titer to P. acnes was 1:8 at the time of diagnosis and declined slowly thereafter over 2½ years. The patient's response to the antibiotic treatment was excellent, and no surgical re-intervention was necessary. The working hypothesis of infective endocarditis can be substantiated by serologic testing, which, if positive, provides one additional minor criterion. Moreover, quantification of the antibody response to P. acnes, though not specific, may assist in the differentiation between contaminants and an infection. This quantification may have implications for the patient management, e.g. indication for and choice of the antibiotic therapy.

    We studied the lipase activities of Propionibacterium granulosum, P. acnes and the suppression of these activities by Jumi-haidoku-to (JHT). Lipase activity of P. acnes biotype III (BIII) was strongest, while that of P. granulosum was faintly expressed. Compared with the control medium, the production of propionic and butyric acids was suppressed by all the tested mediums combined with JHT. The decrease in these acids produced by JHT was significantly higher in P. granulosum than in P. acnes. Although P. acnes BIII may produce a strong effect on acne, the presence of P. granulosum should not be ignored. Further research is required on the correlation between P. acnes and P. granulosum.

    Rosacea is one of the most commonly occurring dermatoses treated by dermatologists. There are multiple therapeutic options available for the treatment of papulopustular rosacea. Rosacea is an inflammatory condition, classically presenting with flushing and/or blushing along with erythema, edema, telangiectasia, papules, pustules, and nodules of the face. Minocycline, a member of the tetracycline family, has demonstrated benefit in the treatment of inflammatory lesions in patients with rosacea. This manuscript highlights the use of a new sustained-release low-dose minocycline 45 mg tablet, with or without azelaic acid, for the treatment of papulopustular rosacea.

    Full Text Available Nos últimos 50 anos, foram publicados inúmeros estudos com a finalidade de comprovar se a dieta está relacionada à etiologia da acne. Embora existam estudos antigos, que são bem difundidos entre os dermatologistas e negam a associação entre acne e dieta, seu delineamento científico é pobre. Recentemente, novos artigos demonstraram evidências contrárias às publicações anteriores.

    Introduction Acne vulgaris is the most frequently diagnosed dermatosis in patients aged between 11 and 30. It is believed that it affects about 80% of persons in this age group or even, taking into account lesions of low intensity, 100% of young people. The role of cytokines in the pathogenesis of acne is not fully known. The TLR2 receptors play a role in the aetiology of acne. Stimulation of TLR2 by Propionibacterium acnes makes the IL-8 and IL-12 concentrations increase. Aim The aim of this work was to determine IL-1β, IL-1α, IL-8 and TNF-α levels in patients’ sera used to test response to TLR2 stimulation. A decrease in the levels of the above mentioned cytokines together with a decrease in sebum production were defined as an indication of efficient treatment with isotretinoin. Material and methods The tests were performed in 155 patients treated for different clinical forms of acne with an oral isotretinoin preparation in the Dermatology Clinic of the Silesian Medical University in Katowice in 2009–2011 – I group and the patients treated with oral isotretinoin 2 and 5 years ago – II group. The control group consisted of 40 healthy individuals. Conclusions Measurements of IL-1α, IL-1β and TNF-α sera concentrations could be assessed in parallel to the improvement of the clinical condition and can constitute a good indication of the efficiency of the isotretinoin treatment.

    Overuse of antibiotics has led to the development of antibiotic-resistant strains of Staphylococcus aureus, which are occurring more frequently within the community. We sought to determine whether long-term antibiotic therapy for acne alter the carriage rate and antibiotic resistance profiles of S aureus. This was a prospective, cross-sectional, quasiexperimental study. Samples of anterior nares were obtained from dermatology patients given a diagnosis of acne vulgaris (n = 263) who were treated with antibiotics (n = 142) or who were not treated with antibiotics (n = 121). Specimens were tested for the presence of S aureus by growth on mannitol salt agar and then isolated on 5% sheep blood agar. Identification was confirmed based on colonial morphology, Gram stain, catalase, and coagulase testing. Antibiotic susceptibility testing was performed using the VITEK 2 system (bioMerieux, Marcy-l'Étoile, France). The S aureus carriage rate was significantly lower in patients with acne treated with antibiotics (6.3%) compared with those not treated with antibiotics (15.7%; P = .016). The percentage of S aureus isolates resistant to 1 or more antibiotics did not significantly differ between the 2 groups (P = .434). Cross-sectional study, patient compliance, and effects of prior acne treatments are limitations. Treatment of patients with acne using antibiotics decreases the S aureus carriage rate but does not significantly alter the antibiotic resistance rates.

    Full Text Available Abstract Background Given that acne is a rare condition in societies with higher consumption of omega-3 (n-3 relative to omega-6 (n-6 fatty acids, supplementation with n-3 may suppress inflammatory cytokine production and thereby reduce acne severity. Methods 13 individuals with inflammatory acne were given three grams of fish oil containing 930 mg of EPA to their unchanged diet and existing acne remedies for 12 weeks. Acne was assessed using an overall severity grading scale, total inflammatory lesion counts, and colorimetry. Findings There was no significant change in acne grading and inflammatory counts at week 12 compared to baseline. However, there was a broad range of response to the intervention on an individual basis. The results showed that acne severity improved in 8 individuals, worsened in 4, and remained unchanged in 1. Interestingly, among the individuals who showed improvement, 7 were classified as having moderate to severe acne at baseline, while 3 of the 4 whose acne deteriorated were classified as having mild acne. Conclusion There is some evidence that fish oil supplementation is associated with an improvement in overall acne severity, especially for individuals with moderate to severe acne. Divergent responses to fish oil in our pilot study indicates that dietary and supplemental lipids are worthy of further investigation in acne.

    During the startup of a full-scale anoxic/aerobic (A/O) biological treatment plant for acrylonitrile wastewater, the removal efficiencies of NH(3)-N and total Kjeldahl nitrogen (TKN) were 1.29 and 0.83% on day 30, respectively. The nitrification process was almost totally inhibited, which was mainly caused by the inhibitory effects of toxic compounds. To eliminate the inhibition, cultivating the bacteria that degrade toxic compounds with patience was applied into the second startup of the biological treatment plant. After 75 days of startup, the inhibitory effects of the toxic compounds on nitrification were eliminated. The treatment plant has been operated stably for more than 3 years. During the last 100 days, the influent concentrations of chemical oxygen demand (COD), NH(3)-N, TKN and total cyanide (TCN) were 831-2,164, 188-516, 306-542 and 1.17-9.57 mg L(-1) respectively, and the effluent concentrations were 257 ± 30.9, 3.30 ± 1.10, 31.6 ± 4.49 and 0.40 ± 0.10 mg L(-1) (n = 100), respectively. Four strains of cyanide-degrading bacteria which were able to grow with cyanide as the sole carbon and nitrogen source were isolated from the full-scale biological treatment plant. They were short and rod-shaped under scanning electron microscopy (SEM) and were identified as Brevundimonas sp., Rhizobium sp., Dietzia natronolimnaea and Microbacterium sp., respectively.

    We examined the relationship between Propionibacterium acnes biotypes and Jumi-haidoku-to (JHT). In all the P. acnes strains tested, the production of propionic acid (PA) and butyric acid (BA) was suppressed in a medium containing 1 mg/ml JHT compared with the control medium without JHT. There were no significant differences in the rates of decreased PA and BA production between P. acnes biotype 3 (B3) and the other biotypes or between isolates from mild skin rash and more severe skin rash. P. acnes B3 was the most commonly identified biotype. The clinical effects on acne due to the anti-P. acnes lipase activity of JHT did not seem to be influenced by the degree of acne rash or the P. acnes biotype.

    Full Text Available Background and Design: Acne vulgaris is a dermatological disorder mainly seen in adolescents. Psychiatric morbidity has been reported in these patients. The aim of the present study was to investigate the quality of life, loneliness and life satisfaction levels in adolescents with acne vulgaris. Materials and Methods: A total of 264 adolescents with acne and 250 controls were included in the study. Acne severity was determined by the Global Acne Grading System (GAGS. Acne Quality of Life Scale (AQOL; developed by Gupta et al., UCLA Loneliness scale (ULS; developed by Russell, Peplau & Ferguson (1978, and the Life Satisfaction Scale (LSS; developed by Diener et al. were used to asses life quality, loneliness and life satisfaction levels, respectively in adolescents with acne and in controls. Results: The mean AQOL and the mean ULS scores were significantly higher in patients (13.67±4.75 vs 11.14±2.94, p<0.001 and 32.15±8.46 vs 30.52±8.70,p=0.031, respectively. The mean LSS score was significantly lower in acne patients (21.82±6.40 than in controls (23.04±6.45, p=0.033. There was a statistically significant difference in the mean LSS scores between the mild, moderate and severe acne patients (22.15±6.32, 21.61±6.20, 16.00±7.26, respectively; Kruskal Wallis Test p=0.036. While there was no significant difference in the mean ULS and LSS scores between the genders. The mean ALQI score was significantly higher in males than in females (p=0.004. Conclusion: Our results indicated that acne quality of life and life satisfaction levels were significantly reduced while loneliness levels were significantly increased in adolescents with acne compared to controls. Our study is important in terms of being the first study investigating the loneliness and life satisfaction levels in acne patients and the relationship between these parameters and severity of acne.

    Full Text Available Acne is the most common conditional skin infection in late adolescence. It has long played the part of ‘Black Spot’ against Natural Beauty, characterized by non-inflammatory pilosebaceous lesions of open or closed comedons, and inflammatory lesions of papules, pustules and nodules. It is typically affected the face, neck, and upper trunk area, where sebaceous follicles is densest in population, however prevalence is about 90% in teenagers. Recent advances have been made in this area with the discovery of Propionibacterium acnes interaction with Toll-Like Receptors (TLRs and free fatty acid that initiates linoleic deficiency, also the role of linoleic acid and PPARs (peroxisome proliferators-activated receptors in inflammation. However multi-drug resistant of bacteria by biofilm formation is also a matter of concern, that render the course of treatment ineffective. With all relevant literature database search upto recent this review focuses on pathogenesis of acne and mechanisms involved in the development of inflammation.

    Full Text Available Background. Eyelid trauma is a common cause of visit to the ophthalmologist, but there are just a few recent epidemiological studies. Purpose of our study was to analyse eyelid injuries according to the mechanism of injury, causes of eyelid injuries and different types of treatment.Methods. A retrospective review of data from patients who received surgical treatment for eyelid injuries at the Ophthalmology Department, Maribor General Hospital in 2000 and 2001 was carried out. Eyelid injuries were divided into a minor trauma with patients treated as outpatients and major trauma patients who needed hospital treatment. According to the mechanism of injury eyelid injuries were divided into a blunt trauma, sharp trauma and combination of both. They according to the localisation injuries were divided into injuries of upper lid, lower lid and both lids at the same time. We looked for causes of eyelid injuries, accompanying injuries and different types of treatment of eyelid injuries.Results. Out of 295 patients 239 were men (81% and 56 were women (19%. 27 patients (9% suffered major trauma and needed hospitalisation while 268 suffered minor trauma and they were treated as outpatients (91%. Blunt trauma was present in 195 cases (66%, sharp trauma was present in 40 cases (14% and in 60 cases (20% the injury was combination of sharp and blunt trauma. The most common causes were sudden falls in 89 cases (30%, followed by violence in 85 cases (29%. 215 patients (73% clinically showed injury of upper lid, 46 patients (16% showed injury of the lower lid and in 34 cases (11% both lids were injured. Accompanying injury of the eyeball was present in 138 patients (47% and face injuries in 17 patients (6%.251 patients (85% needed skin sutures, 6 patients (2% needed skin and subcutaneous tissue suturing, lid margin was treated in 33 cases (11% and canaliculus was treated in 5 cases (2%.Conclusions.

    The benefits and problems associated with traditional hypoglycemic drugs, such as failure of beta cells, hypoglycemia and weight gain, that lead to a worsening of diabetes, are reviewed. New hypoglycemic drugs with incretin effect (glucagon-like peptide-1 agonists and dipeptidyl peptidase 4 inhibitors), achieve, in a glucose dependent manner, an glycosylated hemoglobin reduction without hypoglycemia or increase in body weight. Recently, another group of oral hypoglycemic drugs, sodium-glucose cotransporter type 2 inhibitors, have demonstrated efficacy in diabetes control by inhibiting renal glucose reabsorption. However, long-term effects and cardiovascular prevention remain to be demonstrated. We have more and better drugs nowadays. Hypoglycemic treatment should be customized (glycosylated hemoglobin levels, risk-benefit, risk of hypoglycemia, weight changes, cardiovascular risk), with a combination of drugs being necessary in most cases. However, we do not have yet an ideal hypoglycemic drug. Moreover we must remember that an early and intensive treatment of dyslipidemia and hypertension is essential for the prevention of cardiovascular disease in patients with type 2 diabetes.

    2015-09-01

    Full Text Available Most orally administered polyphenols are metabolized, with very little absorbed as aglycones and/or unchanged forms. Metabolic and pharmacokinetic studies are therefore necessary to understand the pharmacological mechanisms of polyphenols. Jumihaidokuto (JHT, a traditional Japanese medicine, has been used for treatment of skin diseases including inflammatory acne. Because JHT contains various types of bioactive polyphenols, our aim was to clarify the metabolism and pharmacokinetics of the polyphenols in JHT and identify active metabolites contributing to its antidermatitis effects. Orally administered JHT inhibited the increase in ear thickness in rats induced by intradermal injection of Propionibacterium acnes. Quantification by LC-MS/MS indicated that JHT contains various types of flavonoids and is also rich in hydrolysable tannins, such as 1,2,3,4,6-penta-O-galloyl glucose. Pharmacokinetic and antioxidant analyses showed that some flavonoid conjugates, such as genistein 7-O-glucuronide and liquiritigenin 7-O-glucuronide, appeared in rat plasma and had an activity to inhibit hydrogen peroxide-dependent oxidation. Furthermore, 4-O-methylgallic acid, a metabolite of Gallic acid, appeared in rat plasma and inhibited the nitric oxide reaction. JHT has numerous polyphenols; it inhibited dermatitis probably via the antioxidant effect of its metabolites. Our study is beneficial for understanding in vivo actions of orally administered polyphenol drugs.

    Very few clinical trials have investigated the effect of topical acne treatment on scarring. Our objective was to evaluate the efficacy of adapalene 0.3%/benzoyl peroxide 2.5% gel (A0.3/BPO2.5) in atrophic acne scar formation in patients with acne. In this multicenter, randomized, investigator-blinded, vehicle-controlled study, subjects with moderate or severe facial acne (Investigator's Global Assessment [IGA] score 3 or 4; ≥ 25 inflammatory lesions; ten or more atrophic acne scars) applied A0.3/BPO2.5 or vehicle daily per half face for 24 weeks. Subjects with acne requiring systemic treatment were excluded. Assessments included investigator atrophic acne scar count, Scar Global Assessment (SGA), acne lesion count, IGA, skin roughness and skin texture, subject self-assessment of clinical acne-related scars and satisfaction questionnaire, tolerability, and safety. Included subjects (n = 67) had mainly moderate acne (92.5% IGA 3); mean scores at baseline were approximately 40 acne lesions and 12 scars per half face. By week 24, the change from baseline in total scar count was - 15.5% for A0.3/BPO2.5 versus  + 14.4% for vehicle (approximately 30% difference), with a mean of 9.5 scars versus 13.3 per half face, respectively (p vehicle (p vehicle (p vehicle side, most commonly skin irritation (14.9 vs. 6%, respectively). Topical A0.3/BPO2.5 prevented and reduced atrophic scar formation. Scar count increased with vehicle (+ 14.4%) but decreased with A0.3/BPO2.5 (- 15.5%) over 24 weeks.

    Low grade endophthalmitis is usually a chronic indolent inflammation that may be misdiagnosed as noninfectious uveitis. Therefore, this form of endophthalmitis is often unsuccessfully treated with corticosteroids. We describe the case of a patient with low grade endophthalmitis caused by Propionibacterium acnes after cataract surgery. This case report presents the difficulties in establishing the diagnosis of this form of endophthalmitis as well as the benefits of a combined operative therapy with pars plana vitrectomy, intravitreal antibiotics and posterior capsulectomy for successful treatment in such cases.

    2013-04-01

    In this review, we examine published data reporting the efficacy of pharmaceutical agents to treat associated postinflammatory hyperpigmentation commonly seen in skin of color. Retinoids and azelaic acid have been widely used to treat acne. Now there are increasing data describing their use in skin of color for the treatment of both acne and the subsequent postinflammatory hyperpigmentation. Historically, some dermatologists have been hesitant to use retinoids in skin of color because of perceived hypersensitivity in this patient population. However, recent data support the use of retinoids and azelaic acid in skin of color as both safe and beneficial.

    Full Text Available Background: Acne vulgaris is one of the most common skin disorders in youth especially during the puberty. Objective: This in vitro study was performed to determine the antibiotic resistance and sensitivity in acne vulgaris. Materials and Methods: Samples were collected from normal skin and nodulocystic and pustular skin lesions of one hundred youngsters (64 girls, 36 boys among college students in the age range of 18-24 years old. The specimens were cultured individually on blood agar and Muller-Hinton media. The cultures were then incubated under both aerobic and anaerobic conditions for 2 to 7 days. Bacteria were identified and their resistance to common antibiotics was evaluated according to the standard procedures. Results: In aerobic culture of pustular and nodulocystic skin lesions, Staphylococcus aureus was present in 41% of subjects, Staphylococcus epidermidis in 53% and Micrococcus spp in 45% of subjucts. In anaerobic bacterial culture of pustular and nodulocystic skin lesions, Staphylococcus aureus was present in 39%, Propionibacterium acne in 33% and Staphylococcus epidermidis in 21% of subjects. The results of present study revealed that clindamycin and erythromycin were the least effective antibiotics for Propionibacterium acne while tetracycline was the least effective for Staphylococcus aureus in vitro . A synergic effect of benzoyl peroxide, erythromycin or clindamycin was noticed. Rifampin was the most effective antibiotic in vitro . Conclusion: Our results showed that rifampin was the most sensitive antibiotic in vitro for acne vulgaris. To achieve a better treatment, a combination of rifampin with other antibiotics may be more efficient. We suggest in vivo studies for better evaluation and treatment of acne patients with rifampin.

    Acne scars are common and cause cosmetic problems. There is a multitude of treatment options for acne scars, including dermabrasion, chemical peeling, and fillers, but the advent of laser technology has greatly improved the treatment of acne scars. Although several laser systems are available, studies comparing their efficacy are limited. This study compares the results of treatments using resurfacing (carbon dioxide, CO2; erbium-doped yttrium aluminum garnet, Er:YAG) versus fractional (nonablative fractional laser, NAFL; ablative fractional laser, AFL) lasers. A retrospective photographic analysis of 58 patients who underwent laser treatment for facial atrophic acne scars was performed. Clinical improvement was assessed by six blinded investigators with a scale graded from 0 to 10. Adverse events were also noted. Mean improvement scores of the CO2, Er:YAG, NAFL, and AFL groups were 6.0, 5.8, 2.2, and 5.2, respectively. The NAFL group showed a significantly lower score than the other groups. The mean number of treatments was significantly greater in the fractional laser groups than in the resurfacing laser groups. The resurfacing laser groups had a prolonged recovery period and high risk of complications. The Er:YAG laser caused less erythema or pigmentation compared to the CO2 laser. Although the CO2 laser, Er:YAG laser, and AFL improved the acne scars, the CO2 laser had a greater downtime. Three consecutive AFL treatments are as effective as a single treatment with resurfacing lasers, with shorter social downtime periods and less adverse effects.

    2015-01-01

    Full Text Available Background: Acne is a common disorder among adolescents and young adults causing a considerable psychological impact including anxiety and depression. Isotretinoin, a synthetic oral retinoid is very effective in the treatment of moderate to severe acne. But there have been many reports linking isotretinoin to depression and suicide though no clear proof of association has been established so far. Objective: To determine whether oral isotretinoin increases the risk of depression in patients with moderate to severe acne. Materials and Methods: One hundred and fifty patients with moderate to severe acne were treated with oral isotretinoin 0.5 mg/kg/day for a period of 3 months. Their acne and depression scoring was done at baseline and then every month for the first 3 months and then at 6 months. Results: We found that the acne scoring reduced from 3.11 ± 0.49 to 0.65 ± 0.62 (P = < 0.001 at the end of 3 months. Also, the depression scoring decreased significantly from 3.89 ± 4.9 at the beginning of study to 0.45 ± 1.12 (P < 0.001 at the end of 3 months. Both the acne and depression scores continued to remain low at the end of 6 months at 0.5 ± 0.52 (P = < 0.001 and 0.18 ± 0.51 (P = < 0.001, respectively. Conclusions: Our study proves that oral isotretinoin causes significant clearance of acne lesions. It causes significant reduction in depression scores and is not associated with an increased incidence of depression or suicidal tendencies.

    Full Text Available To estimate the prevalence and identify risk factors that may be associated with acne among university students in Syria, a cross-sectional study was conducted in the Syrian International University for Science and Technology in December 2009. A sample of 500 students was chosen. Each participant was subjected to an interview and clinical examination of acne in addition to height and weight measurements. Acne prevalence was 34.7% (172/496. Male students had higher rate of acne compared to females (42.9% versus 23.6%, P<0.0001 and their acne started significantly at a younger age (18.13 versus 19.04 years old, P<0.0001. Face was the commonest site for acne in both males and females. Washing face frequently per day in both sexes has a significant relation with a decreased prevalence of acne. Moreover, psychological stress particularly when the students were away from family was associated with a significant higher rate of acne. We found that the prevalence of acne steadily increased with increasing body mass index. Acne is a health and psychological problem among university students particularly when affecting the face. Several factors such as gender, body mass index, and stress were found to be associated with acne formation.

    2016-01-01

    The relationship between diet and acne is highly controversial. Several studies during the last decade have led dermatologists to reflect on a potential link between diet and acne. This article presents the latest findings on a potential impact that diet can have on pathogenesis of acne vulgaris. The association between diet and acne can no longer be dismissed. Compelling evidence shows that high glycemic load diets may exacerbate acne. Dairy ingestion appears to be weakly associated with acne and the roles of omega-3 fatty acids, dietary fiber, antioxidants, vitamin A, zinc and iodine remain to be elucidated. The question of what the impact of diet is on the course of acne vulgaris still remains unclear. PMID:27279815

    Full Text Available Background and Design: Acne vulgaris is an inflammatory disease of pilosebaceous unit. It usually starts after puberty but may continue into adulthood. We studied Growth hormone (GH and insulin-like growth factor (IGF-1 levels in women patients with acne vulgaris in whom all other hormon levels were normal. We aimed to show any relation of the acne vulgaris lesion type and GH and IGF-1 levels. Material and Method: The study conducted on the postadolesance period woman patients applying to out patient dermatology department with complaint of acne symptoms between Semtember 2005 and July 2006. All other hormonal parameters were normal in patients. 25 healthy similar age women were accepted as control. IGF-I and GH were quantified by solid-phase competitive chemiluminescence assays. Results: There was no difference according to age between the groups (p=0.726. The mean IGF-1 level was 336.5±112.88 ng/ml in patients and 194±31.32 ng/ml in control; the difference was significantly important (p=0.000. The mean GH level was 3.16±4.35 µIU/ml in patients and 1.15±1.21 µIU/ml in control; and the diffrence was not found as important (p=0.03. IGF-1 level was significantly important in patients with noduler involvement (p=0.015, and GH level was also significantly important in patients with cystic involvement (p=0.05. Conclusion: We supported the hypothesis that GH and IGF-1 levels were important in postadolasence period women patients with acne vulgaris. We recommend new studies comparing GH and IGF-1 levels in adolesence and postadolesence period women patients in order to support the role of these hormones in pathogenesis of acne vulgaris.

    Hidradenitis Suppurative-Acne Inversa is one of the most debilitating chronic skin diseases. It seriously affects the emotional and relational life of the patient, it has a significant psychiatric comorbidity and it impairs the quality of life. We present the report of a clinical situation with onset of the illness in a young woman during pregnancy, a case characterized by particular evolution, severe systemic involvement, strong psycho-emotional impact on the patient and impairment of subjective well-being of the caregiver. The clinical evaluation highlights mainly the relevance of the bodily experience, that stands out as a central issue in the sufference of the patient. She feels an uncanny foreignness to herself and a lacerating wound of her identity, related to her desirability, her femininity and her motherhood. Specific personality factors, which are likely to have influenced and guided the experience of illness and the quality of the relationship with the treatment team, are also evaluated. This case exemplifies, at different levels, the clinical complexity of Hidradenitis Suppurative-Acne Inversa and its impact on individual subjectivity. This disease requires an integrated intervention by a multidisciplinary team, providing for the assessment, the treatment and the evaluation of outcomes. It is necessary an effective operational link between different competences, in order to promote the patient compliance and to activate and develop the best care and the right psychological support.

    We evaluated the short-term and long-term effects of the 1550 nm erbium:glass (Er:glass) fractional laser in the treatment of facial acne vulgaris. Forty-five (9 male and 36 female) acne patients were treated 4 times at 4-week intervals with the following parameters: 169 spot density and 15-30 mJ/cm(2) fluence. There was no control group. The laser spots were adjustable (maximum overlap: 20%) according to the treatment area, and delivered in rows in order to cover all the face. Clinical photographs were taken. The IGA scores and lesion counts were performed for each treatment. Their current state was obtained by phone call follow-up to determine the long-term effect and photographs were offered by themselves or taken in hospital. After four treatments, all patients had an obvious reduction of lesion counts and IGA score and the peak lesion counts decreased to 67.7% after the initial four treatment sessions. For long-term effect, 8 patients lost follow-up, hence 37 patients were followed-up. 8 patients were 2-year follow up, 27 at the 1-year follow-up, and all patients at the half-year follow-up. The mean percent reduction was 72% at the half-year follow-up, 79 at the 1-year follow-up and 75% at the 2-year follow-up. Side effects and complications were limited to transient erythema and edema, and few patients suffered from transient acne flare-ups and sensitivity. All patients responded that their skin was less prone to oiliness. In conclusion, acne can be successfully treated by 1550 nm Er:glass fractional laser, with few side effects and prolonged acne clearing.

    Acne vulgaris is one of the most common skin diseases treated by dermatologists. Salts of copper chlorophyllin complex are semi-synthetic naturally-derived compounds with antioxidant, anti-inflammatory and wound healing activity that have not been previously tested topically in the treatment of acne-prone skin with enlarged pores. This single-center pilot study was conducted to assess the efficacy and safety of a liposomal dispersion of topically applied sodium copper chlorophyllin complex in subjects with mild-moderate acne and large, visible pores over a course of 3 weeks. Subjects were supplied with the test product, a topical gel containing a liposomal dispersion of sodium copper chlorophyllin complex (0.1%) with directions to apply a small amount to the facial area twice daily. Clinical assessments were performed at screening/baseline and at week 3. VISIA readings were taken and self-assessment questionnaires were conducted. 10 subjects were enrolled and completed the 3-week study. All clinical efficacy parameters showed statistically significant improvements over baseline at week 3. The study product was well tolerated. Subject questionnaires showed the test product was highly rated. In this pilot study, a topical formulation containing a liposomal dispersion of sodium copper chlorophyllin complex was shown to be clinically effective and well tolerated for the treatment of mild-moderate acne and large, visible pores when used for 3 weeks.

    Acne is a chronic inflammatory disease of pilosebaceous units. Although the acne isnot a life threatening disease, studies have revealed that it has significant effect on self-image and quality of life. The purpose of this paper was to investigate the health-related quality of life in patients with acne in an Iranian context. Dermatology Life Quality Index (DLQI) and Cardiff Acne Disability Index (CADI) were used for measuring quality of life, and severity of acne was measured by Global Acne Grading System (GAGS). The mean (±SD) of DLQI and CADI scores was 6.42 (±4.77) and 5.97 (±2.97), respectively. Acne influenced the quality of life in 51.8% of patients from moderate to very much, and the quality of life was affected by the severity of acne (P < 0.01). Since acne has significant effects on patient's quality of life, the management of patients with acne requires more attention to different aspects of quality of life.

    Full Text Available Acne is a common skin condition with sebum overproduction, hyperkeratosis, Propionibacterium acnes (P. acnes and Staphylococcus aureus, and inflammation. Punica granatum (pomegranate is well-known for its anti-inflammatory effects; however, few studies have discussed the anti-acne effects of pomegranate. In this study, we found that pomegranate extract (PG-E significantly reduced P. acnes-induced edema in Wistar rat ears. Therefore, an evaluation platform using multiple pathogenic mechanisms of acne was established to explore the anti-acne effects of pomegranate. Results showed that PG-E inhibited bacterial growth and lipase activity. Through a bioguided-fractionation-isolation system, four hydrolysable tannins, punicalagin (1, punicalin (2, strictinin A (3, and granatin B (4, were isolated. Compounds 1 and 2 had greater anti-bacterial activities and anti-testosterone-induced HaCaT proliferative effects than the others. Compounds 1, 3, and 4 displayed lipase inhibitory effects. Compound 4 decreased cyclooxygenase-2 expression and downregulated prostaglandin E2 production in heat-killed P. acnes-treated RAW 246.7 cells. In conclusion, PG-E is abundant in hydrolysable tannins that display multiple anti-acne capacities, including anti-bacterial, anti-lipase, anti-keratinocyte proliferation, and anti-inflammatory actions. Hence, PG-E has great potential in the application of anti-acne and skin-care products, and punicalagin (1, the most effective component in PG-E, can be employed as a quality control marker.

    Propionibacterium acnes is a Gram-positive bacterium that colonizes various niches of the human body, particularly the sebaceous follicles of the skin. Over the last years a role of this common skin bacterium as an opportunistic pathogen has been explored. Persistence of P. acnes in host tissue has been associated with chronic inflammation and disease development, for example, in prostate pathologies. This study investigated the intracellular fate of P. acnes in macrophages after phagocytosis. In a mouse model of P. acnes-induced chronic prostatic inflammation, the bacterium could be detected in prostate-infiltrating macrophages at 2 weeks postinfection. Further studies performed in the human macrophage cell line THP-1 revealed intracellular survival and persistence of P. acnes but no intracellular replication or escape from the host cell. Confocal analyses of phagosome acidification and maturation were performed. Acidification of P. acnes-containing phagosomes was observed at 6 h postinfection but then lost again, indicative of cytosolic escape of P. acnes or intraphagosomal pH neutralization. No colocalization with the lysosomal markers LAMP1 and cathepsin D was observed, implying that the P. acnes-containing phagosome does not fuse with lysosomes. Our findings give first insights into the intracellular fate of P. acnes; its persistency is likely to be important for the development of P. acnes-associated inflammatory diseases. PMID:23862148

    Acne, an inflammatory disease of the pilosebaceous unit, is now recognized and investigated as a chronic disease. Since the physiological and psychosocial impact of acne may be long-lasting, the treatment of acne vulgaris poses a formidable challenge for dermatologists. The present study aims at investigating the validity and reliability of a self-developed instrument "acne self-regulation inventory" (ASRI) based on self-regulation theory in assessing the selfregulation ability of acne patients as part of the therapeutic strategy. All proposed items to be included in ASRI, which consisted of four subscales (i.e., self-monitoring, self-judgment, self-reaction, and self-motivation), were first reviewed by 5 experts in the field. Pilot testing of scale reliability and validity of ASRI were then performed by recruiting 144 acne patients, followed by conduction of formal questionnaire survey by enrolling other 90 acne patients to complete a questionnaire comprising the refined ASRI, Cardiff Acne Disability Index (CADI), and Dermatology Life Quality Index (DLQI) to obtain constructive validity to evaluate the associations of ASRI with clinical acne grading scores, CADI, and DLQI. Expert review resulted in the inclusion of totally 31 items for pilot testing (i.e., self-monitoring 6 items, self-judgment 6 items, self-reaction 12 items, and self-motivation 7 items). The differentiating ability of each item was confirmed by significant difference between the higher third scorers and those of the lower third using t-test for independent means (all p<0.001). Moreover, Cronbach's α indicated that deletion of a single item in ASRI did not elevate mean value above 0.958 and removal of each item in the four subscales did not increase the mean value of the set Cronbach's α value for each subscale (i.e., 0.886; 0.860; 0.895; 0.907, respectively), suggesting suitability of the 31 items. A high Cronbach's α coefficient of the whole scale as well as the four subscales (i.e., 0

    Acne vulgaris is the most common skin disease. It affects the young adult female population and generates great impact on physical and mental health. One of the treatments with good results for affected women is combined oral contraceptive pills (COCPs). The aim of this study was to determine the clinical effect of facial acne management with ethinylestradiol 20 µg/dienogest 2 mg in a cohort of Colombian adult women. A cohort of 120 female university students was followed for 12 months. These participants were enrolled in the Sexual and Reproductive Health Program of the Santiago de Cali University. This cohort admitted women between 18 and 30 years old who had chosen to start birth control with ethinylestradiol 20 µg/dienogest 2 mg COCPs, did not have contraindi cations to the use of COCPs, and had been diagnosed with acne. Monthly monitoring of facial acne lesion count was performed. Relative changes in facial lesion count were identified. At the end of follow-up, the percentage of reduction of lesions was 94% and 23% of women had a 100% reduction in acne lesions. In conclusion, the continued use of the ethinylestradiol 20 µg/dienogest 2 mg COCPs reduced inflammatory and non-inflammatory acne lesions in reproductive-age women between 18 and 30 years of age with no severe acne.

    Some studies have suggested an inverse association between acne vulgaris and the acne-related bacterium Propionibacterium acnes and prostate cancer (PCa). Self-reported acne might be an easily obtainable marker to identify men at relatively low risk of PCa and might be incorporated into PCa risk calculators. This study aimed to evaluate the association between self-reported acne and PCa in a large case-referent study. The case group comprised 942 patients with PCa recruited from a population-based cancer registry in 2003 to 2006, 647 of whom met the criteria for aggressive PCa. The referents (n = 2,062) were a random sample of the male general population. All subjects completed a questionnaire on risk factors for cancer, including questions about acne. Odds ratios (ORs) and 95% confidence interval (CI) were calculated using multivariable logistic regression for PCa and aggressive PCa as separate end points, while adjusting for age and family history of PCa. A history of acne was reported by 320 cases (33.9%) and 739 referents (35.8%). Self-reported acne was significantly associated neither with PCa (adjusted OR = 0.95, 95% CI: 0.80-1.12) nor with aggressive PCa (adjusted OR = 0.97, 95% CI: 0.80-1.18). Self-reported acne is not suitable as a marker to identify men at low risk of aggressive PCa. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available There is increasing evidence in support of the interplay of growth hormone (GH, insulin, and insulin-like growth factor-1 (IGF-1 signaling during puberty, which have a causal role in pathogenesis of acne by influencing adrenal and gonadal androgen metabolism. Milk consumption and hyperglycemic diets can induce insulin and IGF-1-mediated PI3K ⁄ Akt-activation inducing sebaceous lipogenesis, sebocyte, and keratinocyte proliferation, which can aggravate acne. Occurence of acne as part of various syndromes also provides evidence in favor of correlation between IGF-1 and acne.

    Dermcidin (DCD), an antimicrobial peptide with a broad spectrum of activity against bacteria such as Propionibacterum acnes, is expressed constitutively in sweat in the absence of stimulation due to injury or inflammation. The aim of this study was to determine the relationship between DCD expression and acne vulgaris associated with P. acnes. The antimicrobial activity of recombinant full-length DCD (50 μg/ml) was 97% against Escherichia coli and 100% against Staphylococcus aureus. Antimicrobial activity against P. acnes ranged from 68% at 50 μg/ml DCD to 83% at 270 μg/ml DCD. DCD concentration in sweat from patients with acne vulgaris (median 9.8 μg/ml, range 6.9-95.3 μg/ml) was significantly lower than in healthy subjects (median 136.7 μg/ml, range 45.4-201.6 μg/ml) (p = 0.001). DCD demonstrated concentration-dependent, but partial, microbicidal activity against P. acnes. These results suggest that reduced DCD concentration in sweat in patients with inflammatory acne may permit proliferation of P. acnes in pilosebaceous units, resulting in progression of inflammatory acne.

    1996-03-01

    The effect of gestodene 75 micrograms (GTD) versus desogestrel 150 micrograms (DSG) combined with 30 micrograms of ethinylestradiol (EE) on acne lesions and plasma androstenedione (A), total testosterone (T), sex hormone binding globulin (SHBG) and "free androgen index" (FAI) was evaluated in an open study on 19 patients aged 18-35 years affected with postpubertal or persistent non-severe acne vulgaris. The patients were randomly allocated into two groups receiving EE-GTD (n = 8) and EE-DSG (n = 11), 21 tablets per cycle for 9 consecutive cycles. Clinical and hormonal evaluations were made between days 17-21 in the cycle before treatment and between days 17-21 of the cycle 3, 6 and 9 of treatment. During treatment, acne improved in most patients, reaching at cycle 9 a low score (absent or minimal) in 62% of the cases in the GTD group (mean acne score = 1.25) and in 90% of the cases in the DSG group (mean acne score = 0.90). Before treatment, about 75% of the patients showed one or more signs of biochemical hyperandrogenism, including elevated FAI (57%), elevated A (15%), elevated total T (15%) and decreased SHBG (21%), and there was evidence of inverse correlation between SHBG and acne scores (p < 0.05). The echogenic texture of the ovaries was multifollicular in 55% of the cases. By the end of the third cycle of treatment, the hormonal changes observed in both groups included significant decreases, with normalization of individual elevated levels of T, and a 3-fold rise of the initial values of plasma SHBG, which showed a further gradual increase at cycle 9 of EE-DSG administration. At cycle 9, normalization of the echogenic ovarian texture was observed. Acne improvement under treatments with estrogen and progestin (EP) could be significantly correlated with the normalization of biochemical hyperandrogenism. In conclusion, the biochemical and clinical efficacy of EE-GTD and EE-DSG indicate that both these preparations can be a good choice in the therapy of acne

    A stable solution of erythromycin was developed using a vehicle of ethanol, propylene glycol, and citric acid buffer. In a controlled, randomized, double-blind comparison, a 2% solution of erythromycin applied to moderately severe facial acne was found to be superior to the blank vehicle in reducing the number of inflamed papules. During a period of 12 weeks, such papules were reduced by 56% in the erythromycin group, compared with 33% in the blank vehicle group. In the erythromycin group, 62% of the subjects had a good or excellent response, compared with 27% of those in the blank vehicle group. Adverse effects were similar in type in both groups and included redness, scaling, dryness, oiliness, burning, itching, and irritation of the eyes. No allergic reactions or skin infections were encountered.

    The combined oral contraceptive containing ethinylestradiol and the selective progestogen, desogestrel, in a phasic regimen (DSG-OC, Tri-merci) has been shown to reduce facial oiliness. This study was designed to evaluate further the effects of this OC on the skin of women with facial seborrhea and mild or moderate acne. This was an open, noncomparative, bicenter study in 60 healthy Russian women, aged 18-30 years, with facial seborrhea and mild or moderate facial acne, who wished to use oral contraception. All women received the OC containing desogestrel (50/100/150 microg) and ethinylestradiol (35/30/30 microg) for three phases of 7 days followed by a 7-day pill-free interval, for six cycles. Seborrhea was assessed using the Sebutape technique, in which strips of adhesive microporous polymeric film pressed onto facial sites are used to assess sebaceous activity. Acne was assessed by counting facial lesions. Subjective evaluations of skin and hair condition, patients' feelings to them and satisfaction with the OC were made using a visual analogue scale (VAS). Assessments were made at baseline, and after one, three and six treatment cycles. Sebutape assessments of seborrhea were significantly improved, on the right and left cheeks, after one treatment cycle, and on the forehead after three treatment cycles. These improvements increased steadily and were much larger at the end of Cycle 6. Acne grades were significantly improved after three and six treatment cycles. VAS scores in response to questions dealing with self-esteem and self-confidence were significantly improved after three cycles and in some cases after just one cycle. The women's views of their skin and hair (greasiness) were correspondingly significantly improved. Subjective assessments indicated that after one, three and six cycles, 69%, 93% and 98%, respectively, of women were satisfied or very satisfied with the DSG-OC. In women with facial seborrhea and mild or moderate acne, the use of DSG

The term AKN is commonly used even though the condition is not a keloid, and the affected individuals do not have a tendency to develop keloids in other areas of the body. It is seen in post pubertal men and is rare after the age of 55 years. A few cases have been reported in females. which has been classified as a primary cicatricial alopecia since the exact cause of acne keloidalis (AK remains unknown. However, a few inciting agents have been suggested which include androgens, inflammation, infection, trauma, genetics, and ingrowing hairs. AK shares some similar features with other forms of cicatricial alopecia and may occur together. Papules, pustules, and sometimes tumorous masses in the nuchal or occipital regions of the scalp hence the name “bumps” evolved in the environment. Despite its common occurrence, only a few seek help in hospital when lesions start to unsightly affect the individual’s quality of life. The presences of the keloidal lesions are more stressful compared to the resulting alopecia. Various attempts to reduce the bumps with corrosives, acids, and car engine oils lead to larger lesions or unsightly scars. Active lesions produce bleeding during haircuts. This is worrisome as a couple of individuals with active AK share shaving instruments at the barber shop and are at risk of acquiring or transmitting blood-borne infections. There is an urgent need to encourage safe shaving habits and treatment of lesions at onset so as to prevent unsightly lesions. Keywords: scarring alopecia, clinical features, treatment challenges

    Full Text Available Purpose. Low-virulence anaerobic bacteria, especially the Propionibacterium acnes (P. acnes, have been thought to be a new pathogeny for a series of disc diseases. However, until now, there has been no histological evidence to confirm this link. The purpose of this study was to confirm the presence of P. acnes in nonpyogenic intervertebral discs via histological observation. Method. Degenerated intervertebral discs were harvested from 76 patients with low back pain and/or sciatica but without any symptoms of discitis or spondylodiscitis. The samples were cultured under anaerobic conditions and then examined using 16S rDNA PCR to screen for P. acnes. Samples found to be positive for P. acnes were stained with hematoxylin-eosin (HE and modified Brown-Brenn staining and observed under a microscope. Results. Here, 16 intervertebral discs were found to be positive for P. acnes via 16S rDNA PCR and the prevalence was 21.05% (16/76. Among them, 7 samples had visible microbes stained with HE and modified Brown-Brenn staining. Morphological examination showed the bacteria to be Gram-positive and rod-shaped, so they were considered P. acnes. Conclusion. P. acnes is capable of colonizing some degenerated intervertebral discs without causing discitis, and its presence could be further confirmed by histological evidence. Targeting these bacteria may be a promising therapy method for some disc diseases.

    Full Text Available Introduction. Acne vulgaris is a common, chronic skin disease that shows a characteristic clinical picture. Skin lesions occur primarily in the seborrheic areas of the body, i.e., the face, back, and chest. Mandelic acid yields very good results when used to treat excessive actinic keratosis (keratosis actinica, hyperpigmentation (lentigo solaris and melasma, and meshlike wrinkles, which are primarily caused by sun-induced aging of the skin. This therapy is well suited for the care of skin with acne vulgaris. Objective. To evaluate the efficacy of dermo-cosmetics containing 5% or 10% mandelic acid for the skin care of patients with acne vulgaris. Material and methods. An open study was carried out on 60 patients with papulo-pustular acne, who applied dermocosmetics to their skin for 2 months. Patients were divided into two subgroups of 30 patients each. One group was tested with a 5% mandelic acid containing cosmetic while the other group was tested with a 10% mandelic acid containing cosmetic. After the treatment was completed, acne severity was evaluated according to the Hellgren-Vincent scale. Results. Physical examinations performed during the study revealed a gradual improvement in the condition of the skin in both groups, with a reduction in the number of pustules, inflammatory nodules, and comedones. The proportion of patients in each group showing a reduction in disease severity according to the Hellgren-Vincent scale was similar. Conclusions. The results of the present study show that products containing 5% or 10% mandelic acid are both safe and effective for the treatment of acne.

  18. Proteomic identification of secreted proteins of Propionibacterium acnes

    2010-01-01

    Background The anaerobic Gram-positive bacterium Propionibacterium acnes is a human skin commensal that resides preferentially within sebaceous follicles; however, it also exhibits many traits of an opportunistic pathogen, playing roles in a variety of inflammatory diseases such as acne vulgaris. To date, the underlying disease-causing mechanisms remain ill-defined and knowledge of P. acnes virulence factors remains scarce. Here, we identified proteins secreted during anaerobic cultivation of a range of skin and clinical P. acnes isolates, spanning the four known phylogenetic groups. Results Culture supernatant proteins of P. acnes were separated by two-dimensional electrophoresis (2-DE) and all Coomassie-stained spots were subsequently identified by MALDI mass spectrometry (MALDI-MS). A set of 20 proteins was secreted in the mid-exponential growth phase by the majority of strains tested. Functional annotation revealed that many of these common proteins possess degrading activities, including glycoside hydrolases with similarities to endoglycoceramidase, β-N-acetylglucosaminidase and muramidase; esterases such as lysophospholipase and triacylglycerol lipase; and several proteases. Other secreted factors included Christie-Atkins-Munch-Petersen (CAMP) factors, glyceraldehyde 3-phosphate dehydrogenase (GAPDH), and several hypothetical proteins, a few of which are unique to P. acnes. Strain-specific differences were apparent, mostly in the secretion of putative adhesins, whose genes exhibit variable phase variation-like sequence signatures. Conclusions Our proteomic investigations have revealed that the P. acnes secretome harbors several proteins likely to play a role in host-tissue degradation and inflammation. Despite a large overlap between the secretomes of all four P. acnes phylotypes, distinct differences between predicted host-tissue interacting proteins were identified, providing potential insight into the differential virulence properties of P. acnes isolates

    Full Text Available Introduction: Antigen-specific antibody has been widely used for immunological analysis in the field of diagnosis as well as in pure scientific research, where the IgY antibodies can be raised against P acnes antigen. Material and Methods: To produce IgY against Propionibacterium acnes, laying hens were immunized with P acnes (MTCC No: 1951 and subsequent booster injections were given. The antibodies produced were purified from the egg yolk of immunized chicken using the polyethylene glycol and ammonium sulfate precipitation method and, further, by Diethylaminoethyl (DEAE cellulose ion-exchange column chromatography. The protein fraction of IgY was isolated from the egg yolk. The separation was rapid, and the success of each step was viewed on Sodium Dodecyl Sulphate-polyacrylamide gel electrophoresis (SDS-PAGE. The reactivity of anti-P acnes was evaluated by the Enzyme-linked immunosorbent assay (ELISA test and the dot-immunoassay. Results: With ELISA, the highest titter of 1:10000 was observed on the 150 th day after vaccination. The results of dot-immunoassay suggested that anti-P acnes IgY developed a brown color as positive reaction, which showed the antigen-antibody binding even after a maximum dilution of 1/500. These results suggest that anti-acne IgY was produced and had strong specific antibody reactivity. Conclusion: The findings indicate that anti-acne IgY is worth utilizing as a preventive agent for acne vulgaris.

    Acne keloidalis nuchae (AKN) also known as folliculitis keloidalis nuchae (FKN) is a chronic form of scarring folliculitis seen mostly in men of African descent. The term AKN is commonly used even though the condition is not a keloid, and the affected individuals do not have a tendency to develop keloids in other areas of the body. It is seen in post pubertal men and is rare after the age of 55 years. A few cases have been reported in females. which has been classified as a primary cicatricial alopecia since the exact cause of acne keloidalis (AK) remains unknown. However, a few inciting agents have been suggested which include androgens, inflammation, infection, trauma, genetics, and ingrowing hairs. AK shares some similar features with other forms of cicatricial alopecia and may occur together. Papules, pustules, and sometimes tumorous masses in the nuchal or occipital regions of the scalp hence the name "bumps" evolved in the environment. Despite its common occurrence, only a few seek help in hospital when lesions start to unsightly affect the individual's quality of life. The presences of the keloidal lesions are more stressful compared to the resulting alopecia. Various attempts to reduce the bumps with corrosives, acids, and car engine oils lead to larger lesions or unsightly scars. Active lesions produce bleeding during haircuts. This is worrisome as a couple of individuals with active AK share shaving instruments at the barber shop and are at risk of acquiring or transmitting blood-borne infections. There is an urgent need to encourage safe shaving habits and treatment of lesions at onset so as to prevent unsightly lesions.

    Full Text Available Thoracic endovascular aortic repair (TEVAR is increasingly used in the treatment of acute type B aortic dissection. Type Ia endoleaks are a common complication of the procedure, but its clinical significance as well as the best treatment strategy remain poorly defined. We present a case of a type Ia endoleak following TEVAR in the treatment of acute type B aortic dissection. Chimney technique approach was used in an attempt to seal the endoleak. Although technical success was suboptimal, the patient remained clinically stable and event free. Data regarding the natural course and management of type Ia endoleaks following TEVAR for aortic dissection are sparse. Future research is required to establish the clinical and technical determinants of the need to treat these endoleaks as well as the best treatment strategy.

It affects the young adult female population and generates great impact on physical and mental health. One of the treatments with good results for affected women is combined oral contraceptive pills (COCPs. The aim of this study was to determine the clinical effect of facial acne management with ethinylestradiol 20 µg/dienogest 2 mg in a cohort of Colombian adult women. A cohort of 120 female university students was followed for 12 months. These participants were enrolled in the Sexual and Reproductive Health Program of the Santiago de Cali University. This cohort admitted women between 18 and 30 years old who had chosen to start birth control with ethinylestradiol 20 µg/dienogest 2 mg COCPs, did not have contraindi­cations to the use of COCPs, and had been diagnosed with acne. Monthly monitoring of facial acne lesion count was performed. Relative changes in facial lesion count were identified. At the end of follow-up, the percentage of reduction of lesions was 94% and 23% of women had a 100% reduction in acne lesions. In conclusion, the continued use of the ethinylestradiol 20 µg/dienogest 2 mg COCPs reduced inflammatory and non-inflammatory acne lesions in reproductive-age women between 18 and 30 years of age with no severe acne.

    Acne vulgaris, a chronic condition associated with overgrowth of Propionibacterium acnes and Staphylococcus epidermidis, is commonly treated with antibiotics. However, the emergence of antibiotic resistance has resulted in a need for alternative therapies. The aim of this study is to develop a topical preparation incorporating essential oils (EOs) for use against acne-associated bacteria and assess its efficacy against prescription therapies Dalacin T and Stiemycin. Antimicrobial screening of rosewood, clove bud and litsea EOs was conducted before interactions between binary and ternary combinations were determined against P. acnes and S. epidermidis (type and clinical isolates) using minimum inhibitory concentrations and fractional inhibitory concentrations. The EOs were characterised by both gas chromatography-mass spectrometry and nuclear magnetic resonance. A combination of 0.53 mg/mL litsea, 0.11 mg/mL rosewood and 0.11 mg/mL clove bud was formulated into herbal distillates and compared with Dalacin T and Stiemycin against antibiotic sensitive and resistant isolates (erythromycin). The distillate with EO had synergistic activity against P. acnes (7log 10 reduction) and indifferent activity against S. epidermidis (6log 10 reduction); antimicrobial activity was either significantly (p ≤ 0.05) more antimicrobial or equivalent to that of Dalacin T and Stiemycin. This formulation may serve as a valuable alternative for the control of acne vulgaris-associated bacteria. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available Acne is the over growth of the commensal bacteria Propionibacterium acnes (P. acnes on human skin. Lauric acid (LA has been investigated as an effective candidate to suppress the activity of P. acnes. Although LA is nearly insoluble in water, dimethyl sulfoxide (DMSO has been reported to effectively solubilize LA. However, the toxicity of DMSO can limit the use of LA on the skin. In this study, LA-loaded poly(ɛ-caprolactone-poly(ethylene glycol-poly(ɛ-caprolactone micelles (PCL-PEG-PCL were developed to improve the bactericidal effect of free LA on P. acnes. The block copolymers mPEG-PCL and PCL-PEG-PCL with different molecular weights were synthesized and characterized using 1H Nuclear Magnetic Resonance spectroscopy (1H NMR, Fourier-transform infrared spectroscopy (FT-IR, Gel Permeation Chromatography (GPC, and Differential Scanning Calorimetry (DSC. In the presence of LA, mPEG-PCL diblock copolymers did not self-assemble into nano-sized micelles. On the contrary, the average particle sizes of the PCL-PEG-PCL micelles ranged from 50–198 nm for blank micelles and 27–89 nm for LA-loaded micelles. The drug loading content increased as the molecular weight of PCL-PEG-PCL polymer increased. Additionally, the minimum inhibitory concentration (MIC and the minimum bactericidal concentration (MBC of free LA were 20 and 80 μg/mL, respectively. The MICs and MBCs of the micelles decreased to 10 and 40 μg/mL, respectively. This study demonstrated that the LA-loaded micelles are a potential treatment for acne.

    Dietary factors have long been implicated in acne pathogenesis. It has recently been hypothesized that low glycemic load diets may influence sebum production based on the beneficial endocrine effects of these diets. To determine the effect of a low glycemic load diet on acne and the fatty acid composition of skin surface triglycerides. Thirty-one male acne patients (aged 15-25 years) completed sebum sampling tests as part of a larger 12-week, parallel design dietary intervention trial. The experimental treatment was a low glycemic load diet, comprised of 25% energy from protein and 45% from low glycemic index carbohydrates. In contrast, the control situation emphasized carbohydrate-dense foods without reference to the glycemic index. Acne lesion counts were assessed during monthly visits. At baseline and 12-weeks, the follicular sebum outflow and composition of skin surface triglycerides were assessed using lipid absorbent tapes. At 12 weeks, subjects on the experimental diet demonstrated increases in the ratio of saturated to monounsaturated fatty acids of skin surface triglycerides when compared to controls [5.3+/-2.0% (mean+/-S.E.M.) vs. -2.7+/-1.7%, P=0.007]. The increase in the saturated/monounsaturated ratio correlated with acne lesion counts(r=-0.39, P=0.03). Increased follicular sebum outflow was also associated with an increase in the proportion of monounsaturated fatty acids in sebum (r=0.49, P=0.006). This suggests a possible role of desaturase enzymes in sebaceous lipogenesis and the clinical manifestation of acne. However, further work is needed to clarify the underlying role of diet in sebum gland physiology.

    Acne pathogenesis is multifactorial and includes inflammation. Combining drugs targeting multiple components of acne pathogenesis is standard practice. To assess the safety and efficacy of dapsone gel 5%, an anti-inflammatory agent, in combination with tazarotene cream 0.1% for treatment of acne vulgaris. Patients were randomized to receive combination therapy (dapsone gel 5% twice-daily plus tazarotene cream 0.1% daily) or monotherapy (tazarotene cream 0.1% daily). Efficacy and safety data were collected after 1, 2, 4, 8, and 12 weeks of treatment. Patients in both arms (n=86, dapsone + tazarotene; n=85, tazarotene) showed significant reductions from baseline in inflammatory, noninflammatory and total lesion counts (P is less than .001 for all). At 12 weeks, patients treated with dapsone plus tazarotene showed a greater reduction from baseline in noninflammatory (comedonal) and total lesion counts than tazarotene-treated patients (noninflammatory, 59.7 percent vs. 46.5 percent, P=.01; total, 63.3% vs. 53.6%, P=.02). The percentage of patients achieving treatment success (an investigator subjective score of 0 [none] or 1 [minimal]) was greater in dapsone plus tazarotene?treated patients (42.2%) than in tazarotene-treated patients (21.8%;P=.01). Both treatments were well tolerated. Combination therapy with dapsone gel 5% plus tazarotene cream 0.1% was more effective than tazarotene monotherapy for treatment of comedonal acne. The results suggest that anti-inflammatory agents such as dapsone can effectively treat early stages of acne (both comedonal and noncomedonal) when used in combination with a retinoid.

  18. Dietary intervention in acne: Attenuation of increased mTORC1 signaling promoted by Western diet.

    Melnik, Bodo

    2012-01-01

    The purpose of this paper is to highlight the endocrine signaling of Western diet, a fundamental environmental factor involved in the pathogenesis of epidemic acne. Western nutrition is characterized by high calorie uptake, high glycemic load, high fat and meat intake, as well as increased consumption of insulin- and IGF-1-level elevating dairy proteins. Metabolic signals of Western diet are sensed by the nutrient-sensitive kinase, mammalian target of rapamycin complex 1 (mTORC1), which integrates signals of cellular energy, growth factors (insulin, IGF-1) and protein-derived signals, predominantly leucine, provided in high amounts by milk proteins and meat. mTORC1 activates SREBP, the master transcription factor of lipogenesis. Leucine stimulates mTORC1-SREBP signaling and leucine is directly converted by sebocytes into fatty acids and sterols for sebaceous lipid synthesis. Over-activated mTORC1 increases androgen hormone secretion and most likely amplifies androgen-driven mTORC1 signaling of sebaceous follicles. Testosterone directly activates mTORC1. Future research should investigate the effects of isotretinoin on sebocyte mTORC1 activity. It is conceivable that isotretinoin may downregulate mTORC1 in sebocytes by upregulation of nuclear levels of FoxO1. The role of Western diet in acne can only be fully appreciated when all stimulatory inputs for maximal mTORC1 activation, i.e., glucose, insulin, IGF-1 and leucine, are adequately considered. Epidemic acne has to be recognized as an mTORC1-driven disease of civilization like obesity, type 2 diabetes, cancer and neurodegenerative diseases. These new insights into Western diet-mediated mTORC1-hyperactivity provide a rational basis for dietary intervention in acne by attenuating mTORC1 signaling by reducing (1) total energy intake, (2) hyperglycemic carbohydrates, (3) insulinotropic dairy proteins and (4) leucine-rich meat and dairy proteins. The necessary dietary changes are opposed to the evolution of

    Inflammation plays an important role in acne pathogenesis, and pro-inflammatory cytokines are key factors in these events. Tumor necrosis factor alpha (TNFα) is a central molecule coded by a gene that shows high level of genetic polymorphisms especially in its promoter region. Single nucleotide polymorphisms (SNPs) of the TNFα gene have been shown to be associated with an increased risk to develop chronic inflammatory diseases. In order to find out if known TNFα regulatory SNPs (-1031T>C, -857C>T, -863C>A, -308G>A, -238G>A) have a role in the development of the inflammatory reactions in acne vulgaris, we analyzed our genomic collection in a retrospective case-control study using the PCR-RFLP method, and we compared the resulting genotype and allele frequencies. There were no significant differences in the observed genotype or allele frequencies between the control and acne group in case of the -1031, -863, -238 SNPs; however, the TNFα -857 minor T allele was found to act as a protective factor in our study population in acne, and a higher occurrence of the minor -308 A allele in female acne patients was also noted. Genetic variants of the TNFα gene may affect the risk of acne vulgaris. Our results can help to elucidate the molecular events leading to acne development.

  20. The role of combined oral contraceptives in the management of acne and seborrhea.

    Acne and seborrhea (or facial oiliness) are related androgenic skin disorders which affect a high proportion of women after menarche. They can have a negative effect on psychological well-being and social life. Androgens play an important role in the pathogenesis of acne through the stimulation of sebum secretion, increasing sebaceous gland size and possibly through follicular hyperkeratinization. Conversely, estrogens decrease sebum production by suppressing gonadotropin release and androgen production and increasing sex hormone binding globulin production. One of the treatment options for these conditions is hormonal therapy, especially for women who require contraception. The effect of combined oral contraceptives in androgenic skin disorders depends on their estrogen:progestogen balance and on the antiestrogenic activity of the progestogen component. Improved understanding of what women value about oral contraceptives suggests that the choice of product should be tailored as much as possible to the individual. Several combined oral contraceptives containing new-generation progestogens (e.g. desogestrel, gestodene) or progestational antiandrogens (e.g. cyproterone acetate, chlormadinone acetate) have demonstrated efficacy in the treatment of women with acne, although comparisons between trials are difficult because of differing endpoints. Seborrhea has been less well studied, but the few studies that are available show an improvement in women with this condition using combined oral contraceptives.

    Woolery-Lloyd, Heather; Kammer, Jenna N

    2011-09-01

    Hyperpigmentation is a common dermatologic condition that is seen in all skin types but is most prominent in skin of color. In skin of color, any inflammation or injury to skin can almost immediately be accompanied by alterations in pigmentation, either hyperpigmentation or hypopigmentation. Post-inflammatory hyperpigmentation can be observed in many skin conditions including acne, eczema, and contact dermatitis and treatment can be challenging. The goal is to reduce the hyperpigmentation without causing undesirable hypopigmentation or irritation in the surrounding area. This review will discuss current research on treatments for hyperpigmentation and approaches to treating this condition. Copyright © 2011 Elsevier Inc. All rights reserved.

    Post-acne atrophic scarring is a major concern for which standardized outcome measures are needed. Traditionally, this type of scar has been classified based on shape; but survey of practicing dermatologists has shown that atrophic scar morphology has not been well enough defined to allow good agreement in clinical classification. Reliance on clinical assessment is still needed at the current time, since objective tools are not yet available in routine practice. Evaluate classification for atrophic acne scars by shape, size, and facial location and establish reliability in assessments. We conducted a non-interventional study with dermatologists performing live clinical assessments of atrophic acne scars. To objectively compare identification of lesions, individual lesions were marked on a high-resolution photo of the patient that was displayed on a computer during the clinical evaluation. The Jacob clinical classification system was used to define three primary shapes of scars 1) icepick, 2) boxcar, and 3) rolling. To determine agreement for classification by size, independent technicians assessed the investigators' markings on digital images. Identical localization of scars was denoted if the maximal distance between their centers was ≤ 60 pixels (approximately 3 mm). Raters assessed scars on the same patients twice (morning/afternoon). Aggregate models of rater assessments were created and analyzed for agreement. Raters counted a mean scar count per subject ranging from 15.75 to 40.25 scars. Approximately 50% of scars were identified by all raters and ~75% of scars were identified by at least 2 of 3 raters (weak agreement, Kappa pairwise agreement 0.30). Agreement between consecutive counts was moderate, with Kappa index ranging from 0.26 to 0.47 (after exclusion of one outlier investigator who had significantly higher counts than all others). Shape classifications of icepick, boxcar, and rolling differed significantly between raters and even for same raters at

    Propionibacterium acnes plays a central role in the pathogenesis of acne and is responsible for severe opportunistic infections. Numerous typing schemes have been developed that allow the identification of phylotypes, but they are often insufficient to differentiate subtypes. To better understand the genetic diversity of this species and to perform epidemiological analyses, high throughput discriminant genotyping techniques are needed. Here we describe the development of a multiple locus variable number of tandem repeats (VNTR) analysis (MLVA) method. Thirteen VNTRs were identified in the genome of P. acnes and were used to genotype a collection of clinical isolates. In addition, publically available sequencing data for 102 genomes were analyzed in silico, providing an MLVA genotype. The clustering of MLVA data was in perfect congruence with whole genome based clustering. Analysis of the clustered regularly interspaced short palindromic repeat (CRISPR) element uncovered new spacers, a supplementary source of genotypic information. The present MLVA13 scheme and associated internet database represents a first line genotyping assay to investigate large number of isolates. Particular strains may then be submitted to full genome sequencing in order to better analyze their pathogenic potential. Copyright © 2015 Elsevier B.V. All rights reserved.

    Prescription patterns for acne/rosacea medications have not been described in the Medicare population, and comparisons across specialties are lacking. To describe the medications used for treating acne/rosacea in the Medicare population and evaluate differences in costs between specialties. A cross-sectional study was performed of the 2008 and 2010 Centers for Medicare and Medicaid Services Prescription Drug Profiles, which contains 100% of Medicare part D claims. Topical antibiotics accounted for 63% of all prescriptions. Patients ≥65 years utilized more oral tetracycline-class antibiotics and less topical retinoids. Specialists prescribed brand name drugs for the most common topical retinoids and most common topical antibiotics more frequently than family medicine/internal medicine (FM/IM) physicians by 6%-7%. Topical retinoids prescribed by specialists were, on average, $18-$20 more in total cost and $2-$3 more in patient cost than the same types of prescriptions from FM/IM physicians per 30-day supply. Specialists (60%) and IM physicians (56%) prescribed over twice the rate of branded doxycycline than FM doctors did (27%). The total and patient costs for tetracycline-class antibiotics were higher from specialists ($18 and $4 more, respectively) and IM physicians ($3 and $1 more, respectively) than they were from FM physicians. The data might contain rare prescriptions used for conditions other than acne/rosacea, and suppression algorithms might underestimate the number of specialist brand name prescriptions. Costs of prescriptions for acne/rosacea from specialists are higher than those from primary care physicians and could be reduced by choosing generic and less expensive options.

    Gender differences in skin and acne have been reported. To evaluate the effect of gender on the efficacy and tolerability of dapsone 5% gel. This was a pooled analysis of data from 2 identical phase 3 randomized, double-blind, and vehicle-controlled trials (DAP0203 and DAP0204) of dapsone 5% gel conducted in the United States and Canada between November 2002 and September 2003. A total of 2,898 patients with acne vulgaris were included in the pooled analysis. Of these, 1,453 patients (753 female, 700 male) received dapsone 5% gel twice daily, and 1,445 patients (767 female, 678 male) received vehicle twice daily. End points included the mean percentage reduction from baseline in acne lesion counts and the proportion of patients achieving clinical success (Global Acne Assessment Scale score of 0, clear skin, or 1, almost clear skin). Assessments were performed at baseline and at weeks 2, 4, 6, 8, and 12. The mean percentage reduction in acne lesion counts at 12 weeks was significantly greater in females than males in both treatment groups. The mean reduction in total lesion counts in dapsone-treated females and males was, respectively, 46.6% vs 35.8% (Pdapsone-treated females than males achieved clinical success (48.6% vs 34.4%; P=.0003). The response to dapsone 5% gel appears to be influenced by gender, with female patients experiencing a significantly greater reduction in acne lesion counts and a significantly higher clinical success rate following 12 weeks of treatment. These data suggest that gender is a novel predictor of outcome that should be considered in acne clinical trial design and analysis.

    1982-01-01

    The chemoattraction of Propionibacterium acnes lipase for neutrophils and the effect of lipase inhibitor and two antibiotic agents on the chemotaxis were evaluated. Of the various fractions tested, partially purified lipase (fraction 2c) was the most active cytotaxin produced by P. acnes. Serum mediators were not required for the generation of chemotaxis by lipase in vitro. Diisopropyl phosphofluoridate at low concentration (10(-4) mM) completely inhibited lipase activity as well as polymorphonuclear leukocyte chemotaxis generated by lipase. Tetracycline hydrochloride and erythromycin base at concentrations of 10(-1) mM and 1 mM, respectively, caused 100% inhibition of PMN migration toward lipase or zymosan-activated serum. The inhibiting activity of the antibiotics was directed against cells independently of any effect on lipase. Chemotaxis by P. acnes lipase suggests a wider role for this enzyme in the inflammatory process and the pathogenesis of acne vulgaris.

    Acne treatment by a mid-infrared laser may be unsatisfactory due to deeply situated acne-affected sebaceous glands which serve as its target. Skin manipulation by vacuum and contact cooling may improve laser-skin interaction, reduce pain sensation, and increase overall safety and efficacy. To evaluate the safety and efficacy of acne treatment using an integrated cooling-vacuum-assisted 1540-nm erbium:glass laser, a prospective interventional study was conducted. It included 12 patients (seven men and five women) suffering from mild-to-moderate acne vulgaris. The device utilizes a mid-infrared 1540-nm laser (Alma Lasers Ltd. Caesarea, Israel), which is integrated with combined cooling-vacuum-assisted technology. An acne lesion is initially manipulated upon contact by a vacuum-cooling-assisted tip, followed by three to four stacked laser pulses (500-600 mJ, 4 mm spot size, and frequency of 2 Hz). Patients underwent four to six treatment sessions with a 2-week interval and were followed-up 1 and 3 months after the last treatment. Clinical photographs were taken by high-resolution digital camera before and after treatment. Clinical evaluation was performed by two independent dermatologists, and results were graded on a scale of 0 (exacerbation) to 4 (76-100 % improvement). Patients' and physicians' satisfaction was also recorded. Pain perception and adverse effects were evaluated as well. All patients demonstrated a moderate to significant improvement (average score of 3.6 and 2.0 within 1 and 3 months, respectively, following last treatment session). No side effects, besides a transient erythema, were observed. Cooling-vacuum-assisted 1540-nm laser is safe and effective for the treatment of acne vulgaris.

    Propionibacterium acnes is a dominant member of the cutaneous microbiota. Herein, we evaluate the effects of different P. acnes strains and propionic acid on autophagy in keratinocytes. Our results showed that P. acnes strain 889 altered the architecture of the mitochondrial network, elevated the levels of LC3B-II, Beclin-1 and phospho-AMPKα, stimulated autophagic flux, facilitated intracellular redistribution of LC3B, increased average number of autophagosomes per cell, and enhanced development of acidic vesicular organelles in the HPV-KER cell line. Propionic acid increased the level of phospho-AMPKα, enhanced lipidation of LC3B, stimulated autophagic flux, as well as facilitated translocation of LC3B into autophagosomes in HPV-KER cells. P. acnes strains 889, 6609 and heat-killed strain 889 also stimulated autophagosome formation in primary keratinocytes to varying degrees. These results indicate that cell wall components and secreted propionic acid metabolite of P. acnes evoke mitochondrial damage successively, thereby trigger AMPK-associated activation of autophagy, which in turn facilitates the removal of dysfunctional mitochondria and promotes survival of keratinocytes. Thus, we suggest that low-level colonization of hair follicles with non-invasive P. acnes strains, by triggering a local increase in autophagic activity, might exert a profound effect on several physiological processes responsible for the maintenance of skin tissue homeostasis.

    Acne vulgaris is a chronic inflammatory disease of the pilosebaceous units (PSU), associated with increased sebum production, abnormal follicular keratinization (hyperkeratinization), follicular overgrowth of Propionibacterium acnes (P. acnes), and increased inflammatory mediator release. Light therapy has attracted medical interests as a safe alternative treatment for acne. Both blue and red light therapies at high doses >10 J/cm 2 have demonstrated marked effects on inflammatory acne lesions. However, few studies have investigated the effects of lower doses of light. The aim of this study is to investigate the biological effects of lower doses of red light at 0.2-1.2 J/cm 2 for acne using an in vitro model previously developed to mimic the inflammation and hyperkeratinization observed clinically in acne. Human epidermal equivalents were topically exposed to an unsaturated fatty acid, oleic acid (OA), followed by red light-emitting diode (LED) light treatments (light-plus-OA treatments). Endpoints evaluated included the proinflammatory cytokine IL-1α, epidermal barrier integrity, as measured by transepithelial electrical resistance (TEER), and stratum corneum (SC) thickness to monitor hyperkeratinization. OA-induced IL-1α release was significantly (P LED light at 0.2, 0.5, and 1.2 J/cm 2 , from 266 ± 11 pg/ml of no-light-plus-OA-treated (OA treatment without light) controls to 216 ± 9, 231 ± 8, and 212 ± 7 pg/ml, respectively. Histological examination showed that SC thickening following OA treatment was reduced from 43% of total epidermis for no-light-plus-OA treatment to 37% and 38% of total epidermis following 0.5 and 1.1 J/cm 2 red light plus OA treatment, respectively (P light-plus-OA treatment improved OA-induced TEER changes from 29% of baseline for no-light-plus-OA treatment, to 36% of baseline. Low level red LED light therapy could provide beneficial effects of anti-inflammation, normalizing pilosebaceous

    Full Text Available Introduction: Acne scars are largely preventable complications of acne. 95% of the scars occur over the face thus impacting the quality of life. Correction of scars is the priority for acne patients. Materials and Methods: Thirty patients with post acne atrophic facial scars attending the OPD during the period from April to October 2013 were offered four sittings of microneedling with PRP on one side and microneedling with vitamin C on other side of the face at an interval of 1 month. Results: Twenty-seven out of the total 30 patients completed the treatment schedule. Two patients were lost to follow up and one dropped out of the study due to severe PIH. Mean age of the patients was 27.5 years. Out of 30 patients, 23 achieved reduction in scarring by one or two grades. Excellent response was seen in five (18.5% patients with platelet-rich plasma (PRP as compared to two (7% patients who received treatment with vitamin C according to physician′s assessment. As far as up gradation by 1 score is considered, i.e., good response, it was similar in both cases. Vitamin C did not prove to be as efficacious as PRP since 10 (37% patients had poor response in vitamin C-treated area compared to only 6 (22.2% patients who underwent PRP therapy, but vitamin C proved to be efficacious in dealing with post inflammatory hyper-pigmentation secondary to acne. Patients were more satisfied with PRP as compared to vitamin C. The results were evaluated and statistical analysis was done using SPSS 16.0.2. Conclusions: Overall results were better with microneedling and PRP. Vitamin C combined with microneedling also showed improvement with respect to firmness and smoothness of skin; as well as post inflammatory hyper-pigmentation. Microneedling combined with PRP proved to be good in treating boxcar and rolling scars but had limited efficacy in dealing with ice pick scars.

    Clays are part of raw materials in different industries. The mineralogical composition and purity greatly influence the application thereof. Chemical treatments applied, such as acid attack, modify their properties and thus their possible uses. Taking in to account that, clay minerals, may differ by more or less resistance to chemical attacks, two types of clay were studied with different mineralogical composition to assess the degree of resistance to chemical attack treatment such as acid. Acid treatments that were applied, differ mainly in the contact time between the solid and the liquid. The solids were studied by X-ray diffraction analysis, chemical analysis and infrared analysis

    The endodontic treatment of teeth with dens invaginatus, characterized by an infolding of enamel and dentin, extending deep into the pulp cavity near the root apex, may be complicated and challenging. The complexity of the internal anatomy may create challenges for the complete removal of diseased pulpal tissue and the subsequent sealing of the canal system. Because of the bizarre root canal anatomy and widely open apex, a combination of nonsurgical and surgical endodontic treatment or extraction is the most common choice of therapy. This article describes case reports of nonsurgical endodontic treatment of Type II dens invaginatus associated with periradicular lesion. PMID:20617071

    Acne dysbiosis happens when there is a microbial imbalance of the over-growth of Propionibacterium acne s ( P. acnes ) in the acne microbiome. In our previous study, we demonstrated that Staphylococcus epidermidis ( S. epidermidis , a probiotic skin bacterium) can exploit glycerol fermentation to produce short-chain fatty acids (SCFAs) which have antimicrobial activities to suppress the growth of P. acnes . Unlike glycerol, sucrose is chosen here as a selective fermentation initiator (SFI) that can specifically intensify the fermentation activity of S. epidermidis , but not P. acnes . A co-culture of P. acnes and fermenting S. epidermidis in the presence of sucrose significantly led to a reduction in the growth of P. acnes . The reduction was abolished when P. acnes was co-cultured with non-fermenting S. epidermidis . Results from nuclear magnetic resonance (NMR) analysis revealed four SCFAs (acetic acid, butyric acid, lactic acid, and succinic acid) were detectable in the media of S. epidermidis sucrose fermentation. To validate the interference of S. epidermidis sucrose fermentation with P. acnes , mouse ears were injected with both P. acnes and S. epidermidis plus sucrose or phosphate buffered saline (PBS). The level of macrophage-inflammatory protein-2 (MIP-2) and the number of P. acnes in ears injected with two bacteria plus sucrose were considerably lower than those in ears injected with two bacteria plus PBS. Our results demonstrate a precision microbiome approach by using sucrose as a SFI for S. epidermidis , holding future potential as a novel modality to equilibrate dysbiotic acne.

    Full Text Available Introduction. Acne vulgaris is a multifactorial disease. Recent study showed that inflammation does have a central role in the formation of both inflammatory and noninflammatory lesions in acne vulgaris. There are various findings of proinflammatory cytokines related to acne vulgaris, but no previous study correlate interleukin- (IL- 19 to acne vulgaris. This pilot study aims to look at difference in IL-19 serum concentration on degrees of severity of acne vulgaris. Methods. This is an analytical observational cross-sectional study. Sample subjects were patients with acne vulgaris who met the inclusion criteria. Enzyme-linked immunosorbent assay (ELISA study was applied to measure IL-19 serum. Result. Analysis test found statistically significant difference between IL-19 serum concentration of group of patients with mild acne vulgaris and that of group of patients with severe acne vulgaris. Moreover, analysis revealed significant difference between IL-19 serum concentration of group of patients with moderate acne vulgaris and that of group of patients with severe acne vulgaris. Conclusions. There are differences in serum levels of IL-19 on the severity of acne vulgaris. The significant difference might show that inflammation has a core role in severity of acne vulgaris, and IL-19 might potentially be related to acne vulgaris.

    Ozenoxacin, a novel non-fluorinated topical quinolone, is used for the treatment of acne vulgaris in Japan. We investigated bactericidal activity and post-antibiotic effect (PAE) of ozenoxacin against Propionibacterium acnes, a major causative bacterium of acne vulgaris. The minimum inhibitory concentrations (MICs) of ozenoxacin against 3 levofloxacin-susceptible strains (MIC of levofloxacin; ≤4 μg/mL) and 3 levofloxacin-resistant strains (MIC of levofloxacin; ≥8 μg/mL) ranged from 0.03 to 0.06 μg/mL and from 0.25 to 0.5 μg/mL, respectively. These MICs of ozenoxacin were almost the same or lower than nadifloxacin and clindamycin. The minimum bactericidal concentrations (MBCs) of ozenoxacin against the levofloxacin-susceptible and -resistant strains were from 0.06 to 8 μg/mL and from 0.5 to 4 μg/mL, respectively. These MBCs were lower than those of nadifloxacin and clindamycin. In time-kill assay, ozenoxacin at 1/4, 1 and 4 times the respective MIC against both levofloxacin-susceptible and -resistant strains showed a concentration-dependent bactericidal activity. Ozenoxacin at 4 times the MICs against the levofloxacin-susceptible strains showed more potent and more rapid onset of bactericidal activity compared to nadifloxacin and clindamycin at 4 times the respective MICs. The PAEs of ozenoxacin at 4 times the MICs against the levofloxacin-susceptible strains were from 3.3 to 17.1 h, which were almost the same or longer than nadifloxacin and clindamycin. In contrast, the PAEs were hardly induced by any antimicrobial agents against the levofloxacin-resistant strains. The present findings suggest that ozenoxacin has a potent bactericidal activity against both levofloxacin-susceptible and -resistant P. acnes, and a long-lasting PAE against levofloxacin-susceptible P. acnes.

    2018-03-01

    Full Text Available Cardiorenal Syndrome Type 1 (CRS-1 is defined as an acute worsening of heart function leading to acute kidney injury and/or dysfunction. It is an important cause of hospitalization which affects the diagnosis as well as the prognosis and treatment of patients. The purpose of this paper is to analyze causes that lead to the development of cardiorenal syndrome type 1 and its clinical consequences, as well as to emphasize the clinical importance of its early detection. The clinical studies and professional papers dealing with etiopathogenesis, diagnosis and treatment of cardiorenal syndrome type 1, have been analyzed. The most important role in the occurrence of cardio renal syndrome type 1 is played by hemodynamic mechanisms, activation of neurohumoral systems, inflammation and imbalance between the production of reactive oxygen species (ROS and nitric oxide (NO. Diagnosis of cardiorenal syndrome type 1 involves biomarkers of acute renal injury among which the most important are: neutrophil gelatinaseassociated lipocalin (NGAL, cystatin C, kidney injury molecule 1 (KIM-1, liver-type fatty acid binding protein (L-FABP, IL-18 and the values of nitrogen compounds in serum. In addition to a pharmacological therapy, various modalities of extracorporeal ultrafiltration are applied in treatment of CRS-1, particularly if there is resistance to the use of diuretic therapy. As opposed to the experimental models, in clinical practice acute renal injury is often diagnosed late so that the measures taken do not give the expected results and the protective role shown in experimental conditions do not give the same results. For all these reasons, it is necessary to analyze the pathophysiology of renal impairment in cardiorenal syndrome as well as detect early indicators of kidney injury that could have clinical benefit and positive impact on reducing the cost of treatment.

    With the aim of elucidating the mechanisms of fluoroquinolones resistance in Propionibacterium acnes, we determined the susceptibility of fluoroquinolones in 211 isolates from patients with acne vulgaris. We identified five isolates (2.4%) with reduced susceptibility to nadifloxacin (minimum inhibitory concentration ≥ 4 μg/ml). Determination of the sequences of the DNA gyrase (gyrA and gyrB) and DNA topoisomerase (parC and parE) genes showed the amino acid substitutions Ser101Leu and Asp105Gly of GyrA in four and one of the isolates, respectively. In vitro mutation experiments showed that low-level fluoroquinolone-resistant mutants with the Ser101Leu or Asp105Gly substitution in GyrA could be obtained from selection with ciprofloxacin and levofloxacin. The pattern of substitution (Ser101Trp in GyrA) caused by nadifloxacin selection was different from that induced by the other fluoroquinolones. In the isolation of further high-level resistant mutants, acquisition of another amino acid substitution of GyrB in addition to those of GyrA was detected, but there were no substitutions of ParC and ParE. In addition, the mutant prevention concentration and mutation frequency of nadifloxacin were lowest among the tested fluoroquinolones. The growth of the Ser101Trp mutant was lower than that of the other mutants. Our findings suggest that the Ser101Trp mutant of P. acnes emerges rarely and disappears immediately, and the risk for the prevalence of fluoroquinolones-resistant P. acnes differs according to the GyrA mutation type. To our knowledge, this study is the first to demonstrate the mechanisms of resistance to fluoroquinolones in P. acnes. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Acne scars are a common result of in ammatory acne, affecting many patients worldwide. Among which, atrophic scars are the most prevalent form, presenting as dermal depressions caused by inflammatory degeneration of dermal collagen. Mid-infrared laser skin interaction is characterized by its modest absorption in water and nite penetration to the mid-dermis. Since collagen is a desirable laser target, 1540-nm wavelength is amenable for collagen remodeling within the depressed area of atrophic scars. To evaluate the safety and efficacy of acne scars treatment using an integrated cooling-vacuum-assisted 1540 nm Erbium: Glass Laser. This interventional prospective study included 25 volunteers (10 men, 15 women) with post acne atrophic scars. Patients were treated with a mid-infrared non-fractional 1540 nm Er:Glass laser (Alma Lasers Ltd. Caesarea, Israel) with integrat- ed cooling- vacuum assisted technology. Acne scars were exposed to 3 stacked laser pulses (400-600 mJ/pulse, 4 mm spot size, frequency of 3 Hz). Patients underwent 3-6 treatment sessions with a 2-3 week interval and were followed-up 1 month and 3 months after the last treatment. Clinical photographs were taken by high resolution digital camera before and after treatment. Clinical evaluation was performed by two independent dermatologists and results were graded on a scale of 0 (exacerbation) to 4 (76%-100% improvement). Patients' and physicians' satisfaction were also recorded (on a 1-5 scale). Pain perception and adverse effects were evaluated as well. Almost all patients (24/25) demonstrated a moderate to significant improvement. Average improvement was 3.9 and 4.1 points on the quartile scale used for outcome assessment 1 and 3 months following the last session, respectively. Patient satisfaction rate was 4.2. Side effects were minimal and transient: erythema, mild transient vesicles, and mild pain or inconvenience. CONCLUSION Cooling-Vacuum-Assisted mid-infrared non-fractional Er:Glass 1540 nm laser

    The use of special silk textiles (Dermasilk) has shown positive effects on chronic inflammatory diseases like lichen sclerosus et atrophicus, atopic dermatitis, diabetic ulcerations, and vulvovaginal candidiasis. Wearing T-shirts of this particular fabric could be useful in the management of patients with acne vulgaris on the back and trunk. Dermasilk T-shirts were given to 14 patients with acne vulgaris papulopustulosa on the back. The patients wore these shirts every night for 6 weeks, and their acne lesions were monitored. Dermasilk represents a polymerisate of fibroin, a silk protein, and antimicrobial AEM5772/5, an unsoluble colorless, odorless ammonium with antifungal and antibacterial ability. Photographic documentation before and after 6 weeks showed a clinically significant reduction in acne lesions on the back without any concomitant treatment or change in lifestyle and living conditions. The use of Dermasilk textiles in other subacute-chronic inflammatory skin diseases has shown positive effects. This is the first report on their safe and effective use in the management of acne vulgaris papulopustulosa corporis. © 2017 The International Society of Dermatology.

    Full Text Available The prevalence of obesity has increased to pandemic levels worldwide and is related to increased risk of morbidity and mortality. Metabolic comorbidities are commonly associated with obesity and include metabolic syndrome, pre-diabetes, and type 2 diabetes. Even if the prevalence of obesity remains stable until 2030, the anticipated numbers of people with diabetes will more than double as a consequence of population aging and urbanization. Weight reduction is integral in the prevention of diabetes among obese adults with pre-diabetes. Lifestyle intervention and weight reduction are also key in the management of type 2 diabetes. Weight loss is challenging for most obese patients, but for those with diabetes, it can pose an even greater challenge due to the weight gain associated with many treatment regimens. This article will review optimal treatment strategies for patients with comorbid obesity and type 2 diabetes. The role of anti-obesity agents in diabetes will also be reviewed. This literature review will provide readers with current strategies for the pharmacologic treatment of obesity and diabetes with a focus on the weight outcomes related to diabetes treatments.

    Oral isotretinoin treatment might influence the levels of vitamin B12 and folic acid. The aim of this study is to compare vitamin B12 and folic acid levels in patients with moderate and severe acne vulgaris with those of the healthy control group and to investigate the effect of isotretinoin treatment on these vitamins. Patients who completed 6 months of isotretinoin therapy for moderate and severe forms of acne vulgaris and a control group consisting of healthy individuals between February 2011 and March 2012 were included in the study. Before isotretinoin therapy and at 6.- months of the therapy, serum vitamin B12 and folic acid levels were measured. In the healthy control group, vitamin B12 and folic acid levels were assessed only once. In total, 120 patients with moderate and severe acne vulgaris who completed 6 months isotretinoin therapy and 100 healthy individuals who constituted the control group were included in the study. Pre-treatment vitamin B12 values of the patient group were found to be statistically significantly higher (P = 0.002), but any statistically significant difference was not detected in folic acid measurements (P = 0.566). A statistically significant decrease was detected in post-treatment vitamin B12 and folic acid levels (P Vitamin B12/folic acid treatment should be given under medical surveillance before and during isotretinoin therapy. Supplementation of these vitamins should be recommended in cases of their deficiency, so as to decrease the risks of neuropsychiatric and occlusive vascular diseases.

    Perceptions and beliefs about treatment can influence patients' adherence to treatment regimens. Perceptions, in turn, are often shaped by patients' sociocultural context. Nepal and the Nepalese have unique sociocultural traditions and beliefs, and their perceptions of diabetes treatment remain largely unexplored. This study explored Nepalese participants' perceptions of diabetes treatment, and whether perceptions differed between the Nepalese living in Australia and Nepal. Face-to-face qualitative interviews (n=48) were conducted with Nepalese participants with type 2 diabetes in Sydney and Kathmandu. All interviews were audio-recorded, transcribed verbatim, and thematically analyzed. Perceptions of diabetes treatment were similar among Nepalese participants in Australia and Nepal. There was a general reluctance to start oral antidiabetic medications and an even greater reluctance to commence parenteral (insulin) therapy. Participants preferred to try lifestyle modifications and alternative treatments such as herbs and "traditional" medicines, particularly as a first step. Unwillingness to take medications was primarily associated with the belief that, once started, these medications needed to be taken for life, and perceptions of long-term harms caused by such medications. Even when commenced on medication, participants were averse to any type of therapy escalation, for example, moving to insulin therapy. Insulin was perceived as the "last option" available for diabetes treatment. Most participants, however, did not find medication taking challenging once they had commenced treatment. Antidiabetic medications were perceived to be harmful and unstoppable once initiated. These perceptions significantly impacted participants' willingness to commence antidiabetic medications and therefore have the potential to adversely affect their medication-taking behavior. This study therefore highlights the need to explore the impact of these perceptions on participants

  19. 2010 American Conference on Neutron Scattering (ACNS 2010)

    2011-06-17

    The ACNS provides a focal point for the national neutron user community to strengthen ties within this diverse group, while at the same time promoting neutron research among colleagues in related disciplines identified as “would-be” neutron users. The American Conference on Neutron Scattering thus serves a dual role as a national user meeting and a scientific meeting. As a venue for scientific exchange, the ACNS showcases recent results and provides forums for scientific discussion of neutron research in diverse fields such as hard and soft condensed matter, liquids, biology, magnetism, engineering materials, chemical spectroscopy, crystal structure, and elementary excitations, fundamental physics and development of neutron instrumentation through a combination of invited talks, contributed talks and poster sessions. As a “super-user” meeting, the ACNS fulfills the main objectives of users' meetings previously held periodically at individual national neutron facilities, with the advantage of a larger and more diverse audience. To this end, each of the major national neutron facilities (NIST, LANSCE, HFIR and SNS) have an opportunity to exchange information and update users, and potential users, of their facility. This is also an appropriate forum for users to raise issues that relate to the facilities. For many of the national facilities, this super-user meeting should obviate the need for separate user meetings that tax the time, energy and budgets of facility staff and the users alike, at least in years when the ACNS is held. We rely upon strong participation from the national facilities. The NSSA intends that the American Conference on Neutron Scattering (ACNS) will occur approximately every two years, but not in years that coincide with the International or European Conferences on Neutron Scattering. The ACNS is to be held in association with one of the national neutron centers in a rotating sequence, with the host facility providing local
