    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 .

    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.

    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.

    To clarify the relationship between major cutaneous microorganisms (Propionibacterium, Staphylococcus and Malassezia spp.) and acne vulgaris (acne), we examined the microbiota quantitatively in the follicular contents of inflammatory acne and on the facial skin of patients with acne. Fifteen Japanese untreated acne outpatients were studied. The follicular contents from inflammatory acne lesions of the face were collected using a comedo extractor. The skin surface samples were obtained by the swab method from 10 cm(2) of facial skin. The microbiota was analyzed using polymerase chain reaction. The microbiota in follicular contents was similar to that on the skin surface, namely, there were large populations of Propionibacterium spp., Staphylococcus spp. and Malassezia spp. Moreover, the number of Malassezia spp. on the skin surface was correlated with that of inflammatory acne and that in follicular contents. This study clarified that there are large populations of Propionibacterium spp., Staphylococcus spp. and Malassezia spp. in follicular contents. These results suggest the possibility that not only Propionibacterium acnes but also other cutaneous resident microorganisms are related to acne. Particularly, we considered that Malassezia spp. is closely related. © 2015 Japanese Dermatological Association.

    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.

    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.

    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.

    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.

    Acne vulgaris is the most common disease of the skin affecting adolescents and young adults causing psychological distress. The combination of antibiotic resistance, adverse effects of topical and systemic anti acne medications and desire for high tech approaches have all led to new enthusiasm for light based acne treatment. Intense pulse light (IPL) therapy has three modes of action in acne vulgaris i.e., photochemical, photo thermal and photo immunological. (1) to study efficacy of IPL therapy in facial acne vulgaris. (2) To compare two fluences - one normal and other subnormal on right and left side of face respectively. (Including settings and design and statistical analysis used). Total 45 patients in age group 16 to 28 years with inflammatory facial acne vulgaris were included in prospective study. Baseline data for each patient was recorded. All patients were given 4 sittings of IPL at 2 weeks interval and were followed for 2 months every 2 weeks. Fluence used was 35J/cm(2) on right and 20J/cm(2) on left side. Percentage reduction in lesion count was calculated at each sitting and follow up and graded as mild (0-25%), moderate (26-50%), good (51-75%) and excellent (76-100%). Side effects were noted. The results were analysed using Mann-Whitney Test. On right side, excellent results were achieved in 10(22%), good in 22(49%) and moderate in 13(29%) patients. On left side excellent were results achieved in 7(15%), good in 19(42%) and moderate in 16(43%) patients. There was no statically significant difference noted in efficacy of two fluences used in treatment of facial acne vulgaris. IPL is a effective and safe option for inflammatory acne vulgaris with minimal reversible side effects. Subnormal fluence is as effective as normal fluence in Indian skin.

    Enlarged facial pores have been esthetic problems and have become a matter of cosmetic concern. Several factors are supposed to be related to the enlargement of facial pores, although scientific evaluations were not performed yet. To assess the correlation between facial pores and possible relating factors such as age, gender, sebum secretion, skin elasticity, and the presence of acne, using objective bioengineering instruments. Sixty volunteers, 30 males and 30 females, participated in this study. Various parameters of facial pores were assessed using the Robo Skin Analyzer. The facial sebum secretion and skin elasticity were measured using the Sebumeter and the Cutometer, respectively. These data were compared and correlated to examine the possible relationship between facial pores and age, sebum secretion and skin elasticity, according to gender and the presence of acne. Male gender and the existence of acne were correlated with higher number of facial pores. Sebum secretion levels showed positive correlation with facial pores. The R7 parameter of skin elasticity was negatively correlated with facial pores, suggesting increased facial pores with decreased skin elasticity. However, the age and the severity of acne did not show a definite relationship with facial pores. Male, increased sebum and decreased skin elasticity were mostly correlated with facial pore development. Further studies on population with various demographic profiles and more severe acne may be helpful to elucidate the potential effect of aging and acne severity on facial pores. © 2011 John Wiley & Sons A/S.

    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

    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.

    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.

    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.

    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.

    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.

    Increased sebum levels are triggering factors of acne vulgaris. No studies on sebum levels exist among acne patients in Africa. Cross-sectional study to determine facial sebum levels, acne lesions and red fluorescence among adolescents (n = 80) with acne vulgaris in Nigeria, who were interviewed and clinically examined. Facial sebum levels were higher among adolescents with acne than among those without. There was a positive correlation between sebum levels and acne lesions in the U zone but not in the T zone. There was also a positive correlation between the size of red fluorescence and acne lesions and mean sebum levels. Both correlations were highly significant in the U zone but not in the T zone. Facial sebum levels are higher among black African acne patients. Sebum is responsible for facial red fluorescence. The U zone may serve as a more reliable site than the T zone for measurements of sebum levels in black African acne patients. © 2015 S. Karger AG, Basel.

    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.

    External application of clay facial masks is a cosmetic procedure generally used to reduce skin lesions and to improve overall skin condition. Collecting pilot data about self-treatment with clay jojoba oil masks on participants with acne-prone, lesioned skin and acne. Open, prospective, observational pilot study: Participants received written information, instructions, and questionnaires without direct contact with the study physician. For 6 weeks, they applied the masks 2-3 times per week. The primary outcome is the difference of skin lesions: baseline vs. after 6 weeks. 194 participants (192 female, 2 male, mean age (± SE) (32.3 ± 0.7 years) returned questionnaires and diaries. 133 of these participants returned complete and precise lesion counts (per-protocol (PP) collective). A 54% mean reduction in total lesion count was observed after 6 weeks of treatment with clay facial mask. Both inflammatory and non-inflammatory skin lesions were reduced significantly after treatment compared to baseline: Median counts (MC) of pustules per affected participant were reduced from 7.0 ± 0.9 to 3.0 ± 0.5 (mean individual reduction (MIR) = 49.4%), the MC of the papules from 3.5 ± 2.2 to 1.0 ± 0.4 (MIR = 57.3%), the MC of cysts from 2.0 ± 0.8 to 0.5 ± 0.4 (MIR = 68.6%) and the MC of comedones from 26.5 ± 6.3 to 16.0 ± 4.0 (MIR = 39.1%). DLQI-average score decreased from 5.0 ± 4.5 (mean ± SE) before to 2.1 ± 2.8 after treatment. The present study gives preliminary evidence that healing clay jojoba oil facial masks can be effective treatment for lesioned skin and mild acne vulgaris. Copyright © 2012 S. Karger AG, Basel.

    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

    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.

    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

    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.

    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.

    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.

  13. 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.

    Acne vulgaris, commonly called as acne, is a skin problem that occurs when oil and dead skin cells clog up in a person's pores. This is because hormones change which makes the skin oilier. The problem is people really do not know the real assessment of sensitivity of their skin in terms of fluid development on their faces that tends to develop acne vulgaris, thus having more complications. This research aims to assess Acne Vulgaris using luminescent visualization system through optical imaging and integration of image processing algorithms. Specifically, this research aims to design a prototype for facial fluid analysis using luminescent visualization system through optical imaging and integration of fluorescent imaging system, and to classify different facial fluids present in each person. Throughout the process, some structures and layers of the face will be excluded, leaving only a mapped facial structure with acne regions. Facial fluid regions are distinguished from the acne region as they are characterized differently.

    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.

    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.

    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.

    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.

    Acne vulgaris is a multifactorial disorder which is ideally treated with combination therapy with topical retinoids and antibiotics. The present study was conducted to compare the efficacy and safety of tazarotene plus clindamycin against adapalene plus clindamycin in facial acne vulgaris. This study is a randomized, open-label, parallel design clinical trial conducted on 60 patients with facial acne at the outpatient dermatology department in a tertiary healthcare center. The main outcome measures were change in the acne lesion count, Investigator's Static Global Assessment (ISGA) score, Global Acne Grading System (GAGS) score, and Acne-Specific Quality of Life Questionnaire (Acne-QoL) at the end of 4 weeks of therapy. After randomization one group (n = 30) received tazarotene 0.1% plus clindamycin 1% gel and another group (n = 30) received adapalene 0.1% plus clindamycin 1% gel for 1 month. At follow-up, all the parameter were reassessed. In both treatment regimens the total number of facial acne lesions decreased significantly. The difference in the change in the total count between the two combination regimens was also significant [6.51, 95% confidence interval (CI) 1.91-11.09, p = 0.007]. A ≥50% reduction in the total lesion count from the baseline levels was achieved by 71% of patients in the tazarotene plus clindamycin group and 22% of patients in the adapalene plus clindamycin group (p = 0.0012). The difference in the change of inflammatory (p = 0.017) and non-inflammatory (p = 0.039) lesion counts in the tazarotene plus clindamycin group were significantly higher than the adapalene plus clindamycin group. The difference in change of the GAGS score was also significantly higher in the tazarotene plus clindamycin group (p = 0.003). The ISGA score improved in 17 patients in the tazarotene plus clindamycin group versusnine patients in the adapalene plus clindamycin group (p = 0.04). The change of total quality-of-life score was found to be

    The postadolescent form of acne papulopustulosa, also referred to as 'acne tarda' can have substantial negative impact on Quality of Life, especially in adult female patients. Although the Dermatology Life Quality Index (DLQI) is widely used, empirical evidence about its performance in adult female acne patients is lacking. In this prospective cohort study, we have investigated the sensitivity to change of the DLQI in 53 female adult acne patients with mild to moderate facial acne treated with azelaic acid (AzA) 15% gel twice daily over 24 weeks. Mean Investigator Static Global Assessment (ISGA) score was 2.3 (SD 0.5) at baseline and ranged from 0.9 (SD 0.3) to 2.1 (SD 0.4) at the end of the study in the 'Highly Improved' and 'Unchanged' responder groups respectively. The mean baseline DLQI score was 5.1 (SD 4.2). The Effect Size in the responder group 'Highly Improved' was 0.66; in group 'Improved' 0.62 and 0.23 in group 'Unchanged'. At the end of study, the mean DLQI score ranged from 1.1 (SD 1.5) in the 'Highly Improved' group to 3.7 (SD 6.0) in the 'Unchanged' group. The results support the sensitivity to change of the DLQI in this population. © 2016 European Academy of Dermatology and Venereology.

    Propionibacterium acnes (P. acnes) is a commensal bacterium which is possibly involved in acne inflammation. The saturated fatty acid, lauric acid (C12:0) has been shown to possess antibacterial and anti-inflammatory properties against P. acnes. Little is known concerning the potential effects of its decanoic counterpart, capric acid (C10:0). To examine the antibacterial and anti-inflammatory activities of capric acid against P. acnes and to investigate the mechanism of the anti-inflammatory action. The antimicrobial activity of fatty acids was detected using the broth dilution method. An evaluation of P. acnes-induced ear edema in mice was conducted to evaluate the in vivo anti-inflammatory effect. To elucidate the in vitro anti-inflammatory effect, human SZ95 sebocytes and monocytic THP-1 cells were treated with P. acnes alone or in the presence of a fatty acid. The mRNA levels and secretion of pro-inflammatory cytokines were measured by qRT-PCR and enzyme immunoassay, respectively. NF-κB activation and MAPK expression were analyzed by ELISA and Western blot, respectively. Lauric acid had stronger antimicrobial activity against P. acnes than capric acid in vitro and in vivo. However, both fatty acids attenuated P. acnes-induced ear swelling in mice along with microabscess and significantly reduced interleukin (IL)-6 and CXCL8 (also known as IL-8) production in P. acnes-stimulated SZ95 sebocytes. P. acnes-induced mRNA levels and secretion of IL-8 and TNF-α in THP-1 cells were suppressed by both fatty acids, which inhibited NF-κB activation and the phosphorylation of MAP kinases. Our data demonstrate that both capric acid and lauric acid exert bactericidal and anti-inflammatory activities against P. acnes.

    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.

    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.

    Full Text Available The publication provides an overview of current scientific and medical literature devoted to the study of mechanisms of immunopathogenesis of acne. The concept of the pathophysiology and immunopathogenesis of acne expanded significantly in recent years, many scientists have pointed out the link between the presence of acne and disorders of the endocrine, nervous, digestive and immune systems. Despite the fact that the individual links in the pathogenesis of acne are well studied, there are still questions about the role of commensal Propionibacterium acnes in the initiation and development of acne. So far there is no information on the number of P. acnes in healthy and diseased skin, the relationship between the numder of P. acnes and severity of the disease, also an important question remains unanswered — why do P. acnes cause inflammation for some people, while it don`t for the others? Despite the presence of bacterial factor in the pathogenesis of acne, there are a large number of studies showing that the nature of the patient’s immune response to P. acnes is more important than the infectious agent. For quite a long time data was received that proinflammatory cytokines play an important role in the initiation of acne. Interleukins IL-6 and IL-8 are involved in the stimulation of sebum hypersecretion, and subpopulation Th1 derived from a patient with acne, recognize P. acnes antigens. A number of recently obtained results suggest that P. acnes is a potent inducer of Th17 and Th1, and the study of the role of proinflammatory cytokines in the development of acne suggests new possibilities of acne therapy. Presented in this article is a clinical case clearly illustrates the part of the immune inflammation in acne. Prospective areas of research on the role of signaling molecules in the pathogenesis of acne are covered: such as the mechanism of action of nitric oxide on the secretion of interleukin IL-1 beta, which was shown as

    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.

    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.

    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.

    Full Text Available Granuloma faciale (GF is a rare chronic inflammatory skin disease characterized by single or multiple reddish-brown cutaneous plaques or nodules. Although this condition is benign, its clinical course is extremely chronic with poor response to therapy. The typical histopathological features of GF include vasculitis with mixed cellular infiltration; however, its etiopathogenesis remains unknown. Here, we describe the case of a 76-year-old man with GF resistant to topical steroids. Biopsy of the lesion revealed i dense mixed inflammatory cellular infiltrates of lymphocytes, histiocytes, neutrophils, and eosino­phils, ii mild perivascular nuclear dust and swollen endothelium of blood vessels, and iii a narrow Grenz zone beneath the epidermis. Immunohistochemical staining demonstrated mixed cellular infiltrates intermixed with CD1a+ dendritic cells, CD68+ histiocytes, and CD4+ and CD8+ T cells.

    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.

    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.

    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

    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.

    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.

    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

    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.

    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.

    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.

    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.

    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.

    Facial allodynia is a migraine symptom that is generally considered to represent a pivotal point in migraine progression. Treatment before development of facial allodynia tends to be more successful than treatment afterwards. As such, understanding the underlying mechanisms of facial allodynia may lead to a better understanding of the mechanisms underlying migraine. Migraine facial allodynia is modeled by applying inflammatory soup (histamine, bradykinin, serotonin, prostaglandin E2) over the dura. Whether glial and/or immune activation contributes to such pain is unknown. Here we tested if trigeminal nucleus caudalis (Sp5C) glial and/or immune cells are activated following supradural inflammatory soup, and if putative glial/immune inhibitors suppress the consequent facial allodynia. Inflammatory soup was administered via bilateral indwelling supradural catheters in freely moving rats, inducing robust and reliable facial allodynia. Gene expression for microglial/macrophage activation markers, interleukin-1β, and tumor necrosis factor-α increased following inflammatory soup along with robust expression of facial allodynia. This provided the basis for pursuing studies of the behavioral effects of 3 diverse immunomodulatory drugs on facial allodynia. Pretreatment with either of two compounds broadly used as putative glial/immune inhibitors (minocycline, ibudilast) prevented the development of facial allodynia, as did treatment after supradural inflammatory soup but prior to the expression of facial allodynia. Lastly, the toll-like receptor 4 (TLR4) antagonist (+)-naltrexone likewise blocked development of facial allodynia after supradural inflammatory soup. Taken together, these exploratory data support that activated glia and/or immune cells may drive the development of facial allodynia in response to supradural inflammatory soup in unanesthetized male rats.

    Acne vulgaris causes erythematous papulopustular lesions in active stage and often leave behind residual scarring and pigmentation. 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.

    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.

    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.

    Full Text Available The antibacterial and anti-inflammatory potential of natural, plant-derived compounds has been reported in many studies. Emerging evidence indicates that plant-derived essential oils and/or their major compounds may represent a plausible alternative treatment for acne, a prevalent skin disorder in both adolescent and adult populations. Therefore, the purpose of this study was to develop and subsequently analyze the antimicrobial activity of a new multi-agent, synergic formulation based on plant-derived antimicrobial compounds (i.e., eugenol, β-pinene, eucalyptol, and limonene and anti-inflammatory agents for potential use in the topical treatment of acne and other skin infections. The optimal antimicrobial combinations selected in this study were eugenol/β-pinene/salicylic acid and eugenol/β-pinene/2-phenoxyethanol/potassium sorbate. The possible mechanisms of action revealed by flow cytometry were cellular permeabilization and inhibition of efflux pumps activity induced by concentrations corresponding to sub-minimal inhibitory (sub-MIC values. The most active antimicrobial combination represented by salycilic acid/eugenol/β-pinene/2-phenoxyethanol/potassium sorbate was included in a cream base, which demonstrated thermodynamic stability and optimum microbiological characteristics.

    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.

    Our laboratory previously developed a novel neuropathic and inflammatory facial pain model for mice referred to as the Trigeminal Inflammatory Compression (TIC) model. Rather than inducing whole nerve ischemia and neuronal loss, this injury induces only slight peripheral nerve demyelination triggering long-term mechanical allodynia and cold hypersensitivity on the ipsilateral whisker pad. The aim of the present study is to further characterize the phenotype of the TIC injury model using specific behavioral assays (i.e. light-dark box, open field exploratory activity, and elevated plus maze) to explore pain- and anxiety-like behaviors associated with this model. Our findings determined that the TIC injury produces hypersensitivity 100% of the time after surgery that persists at least 21 weeks post injury (until the animals are euthanized). Three receptive field sensitivity pattern variations in mice with TIC injury are specified. Animals with TIC injury begin displaying anxiety-like behavior in the light-dark box preference and open field exploratory tests at week eight post injury as compared to sham and naïve animals. Panic anxiety-like behavior was shown in the elevated plus maze in mice with TIC injury if the test was preceded with acoustic startle. Thus, in addition to mechanical and cold hypersensitivity, the present study identified significant anxiety-like behaviors in mice with TIC injury resembling the clinical symptomatology and psychosocial impairments of patients with chronic facial pain. Overall, the TIC injury model's chronicity, reproducibility, and reliability in producing pain- and anxiety-like behaviors demonstrate its usefulness as a chronic neuropathic facial pain model.

    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.

    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.

    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.

    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. Phototherapy is efficacious for moderate to severe facial acne vulgaris. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    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.

    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.

    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.

    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.

    Very early onset inflammatory bowel disease, diagnosed in children ≤5 years old, can be the initial presentation of some primary immunodeficiencies. In this study, we describe a 17-month-old boy with recurrent infections, growth failure, facial anomalies, and inflammatory bowel disease. Immune evaluation, whole-exome sequencing, karyotyping, and methylation array were performed to evaluate the child's constellation of symptoms and examination findings. Whole-exome sequencing revealed that the child was homozygous for a novel variant in ZBTB24, the gene associated with immunodeficiency, centromere instability, and facial anomalies type-2 syndrome. This describes the first case of inflammatory bowel disease associated with immunodeficiency, centromere instability, and facial anomalies type-2 syndrome in a child with a novel disease-causing mutation in ZBTB24 found on whole-exome sequencing.

    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

    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.

    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.

    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

    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.

    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.

    2014-01-01

    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.

    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.

    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.

    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. We argue that the disease-causing potential of

    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.

    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.

    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..

    The aim of this prospective study was to determine the influence of anti-inflammatory drugs on the severity of odontogenic cellulitis in patients admitted to our hospital emergency unit. The study was made from April 30 to October 31 2006. The clinical and pharmacological data was prospectively collected at admission, during hospitalization, and during systematic follow-up. We first studied the whole population and then compared the 2 groups: patients having received anti-inflammatory drugs before admission or not. Two hundred and sixty-seven patients were included. The only severity criterion significantly different between the 2 groups was spreading of cervical lymphangitis (P=0.028). None of the 4 studied parameters was identified as a risk factor for spreading of cervical lymphangitis in multivariate analysis: anti-inflammatory use (OR=5.99, 95%CI [0.71-50.88]), alcohol abuse (OR=4.00, 95%CI [0.66-24.12]), dental hygiene (OR=1.53, 95%CI [0.36-6.56]), and tobacco use (OR=0.27, 95%CI [0.57-1.28]). The use of anti-inflammatory drugs during the initial phase of an odontogenic infection was not related to the severity of infection. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    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.

    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.

    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.

    herbal medicine, acupuncture, cupping therapy, diet, purified bee venom (PBV), and tea tree oil. A pharmaceutical company funded one trial; the other trials did not report their funding sources.Our main primary outcome was 'Improvement of clinical signs assessed through skin lesion counts', which we have reported as 'Change in inflammatory and non-inflammatory lesion counts', 'Change of total skin lesion counts', 'Skin lesion scores', and 'Change of acne severity score'. For 'Change in inflammatory and non-inflammatory lesion counts', we combined 2 studies that compared a low- with a high-glycaemic-load diet (LGLD, HGLD) at 12 weeks and found no clear evidence of a difference between the groups in change in non-inflammatory lesion counts (mean difference (MD) -3.89, 95% confidence interval (CI) -10.07 to 2.29, P = 0.10, 75 participants, 2 trials, low quality of evidence). However, although data from 1 of these 2 trials showed benefit of LGLD for reducing inflammatory lesions (MD -7.60, 95% CI -13.52 to -1.68, 43 participants, 1 trial) and total skin lesion counts (MD -8.10, 95% CI -14.89 to -1.31, 43 participants, 1 trial) for people with acne vulgaris, data regarding inflammatory and total lesion counts from the other study were incomplete and unusable in synthesis.Data from a single trial showed potential benefit of tea tree oil compared with placebo in improving total skin lesion counts (MD -7.53, 95% CI -10.40 to -4.66, 60 participants, 1 trial, low quality of evidence) and acne severity scores (MD -5.75, 95% CI -9.51 to -1.99, 60 participants, 1 trial). Another trial showed pollen bee venom to be better than control in reducing numbers of skin lesions (MD -1.17, 95% CI -2.06 to -0.28, 12 participants, 1 trial).Results from the other 31 trials showed inconsistent effects in terms of whether acupuncture, herbal medicine, or wet-cupping therapy were superior to controls in increasing remission or reducing skin lesions.Twenty-six of the 35 included studies reported

    Acne vulgaris is a disease of the pilosebaceous unit. Increased sebum lipogenesis by sebaceous gland is the major factor in the pathophysiology of acne. LXRα have been recognized in the regulation of genes involved in lipid biosynthesis. Activation of LXRα inhibits proliferation, increase lipogenesis and improve differentiation of sebocytes. Aim: To investigate the level of tissue expression of LXRα in inflammatory and non inflammatory acne lesions and in comparison with normal skin. Patients and methods: Seventeen patients with inflammatory and non inflammatory acne lesions and sixteen age and sex comparable healthy volunteers as control were included in the study. Punch skin biopsies were taken from the acne lesions and normal skin of the volunteers for detection of gene expression of LXRα by RT- PCR. Results: the level of LXRα was significantly higher in the lesional skin either inflammatory (with a mean of 1188.52 ± 129.5) or comedonal acne (with a mean of 892.52 ± 66.08) in a statistically significant manner than the controls (with a mean of 600.50 ± 95.30) where the P value was <0.001. In addition, the level of LXRα was significantly higher in inflammatory acne (with a mean of 1188.52 ± 129.5) in a statistically significant manner) than comedonal acne (with a mean of 892.52 ± 66.08) where the P value was <0.001. Conclusion: the significant increase in the level of LXRα in acne lesions compared to controls suggesting that LXRα may have a role in the pathogenesis of acne vulgaris itself and is not a consequence of inflammation. In addition, it may play a role in the progression of the disease from comedonal to inflammatory. Further studies are recommended to evaluate the therapeutic benefits of the use of LXRα antagonists as a new therapeutic modality for acne vulgaris.

    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 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.

    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.

    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.

    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)

    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.

    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

    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)

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

    trials in two meta-analyses, with two trials in each meta-analysis. The categories of CAM included herbal medicine, acupuncture, cupping therapy, diet, purified bee venom (PBV), and tea tree oil. A pharmaceutical company funded one trial; the other trials did not report their funding sources. Our main primary outcome was ’Improvement of clinical signs assessed through skin lesion counts’, which we have reported as ’Change in inflammatory and non-inflammatory lesion counts’, ’Change of total skin lesion counts’, ’Skin lesion scores’, and ’Change of acne severity score’. For ’Change in inflammatory and non-inflammatory lesion counts’, we combined 2 studies that compared a low- with a high-glycaemic-load diet (LGLD, HGLD) at 12 weeks and found no clear evidence of a difference between the groups in change in non-inflammatory lesion counts (mean difference (MD) −3.89, 95% confidence interval (CI) −10.07 to 2.29, P = 0.10, 75 participants, 2 trials, low quality of evidence). However, although data from 1 of these 2 trials showed benefit of LGLD for reducing inflammatory lesions (MD −7.60, 95% CI −13.52 to −1.68, 43 participants, 1 trial) and total skin lesion counts (MD −8.10, 95% CI −14.89 to −1.31, 43 participants, 1 trial) for people with acne vulgaris, data regarding inflammatory and total lesion counts from the other study were incomplete and unusable in synthesis. Data from a single trial showed potential benefit of tea tree oil compared with placebo in improving total skin lesion counts (MD −7.53, 95% CI −10.40 to −4.66, 60 participants, 1 trial, low quality of evidence) and acne severity scores (MD −5.75, 95% CI −9.51 to −1.99, 60 participants, 1 trial). Another trial showed pollen bee venom to be better than control in reducing numbers of skin lesions (MD −1.17, 95% CI −2.06 to −0.28, 12 participants, 1 trial).

    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.

    Full Text Available Acne vulgaris is a chronic inflammatory disorder of the sebaceous follicles. Propionibacterium acnes (P. acnes, a gram-positive anareobic bacterium, plays a critical role in the development of these inflammatory lesions. This study aimed at determining whether reactive oxygen species (ROS are produced by keratinocytes upon P. acnes infection, dissecting the mechanism of this production, and investigating how this phenomenon integrates in the general inflammatory response induced by P. acnes. In our hands, ROS, and especially superoxide anions (O2(*-, were rapidly produced by keratinocytes upon stimulation by P. acnes surface proteins. In P. acnes-stimulated keratinocytes, O2(*- was produced by NAD(PH oxidase through activation of the scavenger receptor CD36. O2(*- was dismuted by superoxide dismutase to form hydrogen peroxide which was further detoxified into water by the GSH/GPx system. In addition, P. acnes-induced O2(*- abrogated P. acnes growth and was involved in keratinocyte lysis through the combination of O2(*- with nitric oxide to form peroxynitrites. Finally, retinoic acid derivates, the most efficient anti-acneic drugs, prevent O2(*- production, IL-8 release and keratinocyte apoptosis, suggesting the relevance of this pathway in humans.

    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.

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

    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.

    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.

    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.

    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.

    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.

    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 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.

    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.

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 Acne dysbiosis happens when there is a microbial imbalance of the over-growth of Propionibacterium acnes (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.

    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.

    The fluorescence findings of several dermatological diseases, such as erythrasma, tinea versicolor, and acne are helpful for diagnosis and follow-up. However, many experience difficulty taking photographic images of fluorescence. The aim of this study was to develop a 405 nm light-emitting diode (LED) system for fluorescence digital photography of acne and to determine whether such a diode can be used to evaluate acne. Eight healthy acne patients were compared with controls by fluorescence digital photography using a digital camera equipped with a 405 nm LED illuminator. Digital photographs were taken by two different ways of exposure, i.e. appropriate exposure level and longer exposure. One side of the nose, cheek, and glabella was compared. The numbers and extents of fluorescence dots were counted and measured. As normal controls, seven individuals with apparent oiliness and no acne were enrolled. Red fluorescent facial dots were observed and photographed digitally using the 405 nm LED illuminator. These were more numerous and extensive on the glabella and cheeks of acne patients. Fluorescence digital photography of acne was successfully performed using a 405 nm LED illuminator. This illuminator could be used for acne evaluations.

    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.

  5. Dietary intervention in acne

    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

    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

    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.

    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.

    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.

    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.

    Objective: To evaluate if nonprescription topical agents may provide positive outcomes in the management of mild-to-moderate facial seborrheic dermatitis by reducing inflammation and scale production through clinical evaluation and erythema-directed digital photography. Setting: Open-label, prospective, not-blinded, intra-patient, controlled, clinical trial (target area). Participants: Twenty adult subjects affected by mild-to-moderate facial seborrheic dermatitis were enrolled and instructed to apply the study cream two times daily, initially on a selected target area only for seven days. If the subject developed visible improvement, it was advised to extend the application to all facial affected area for 21 additional days. Measurement: Efficacy was evaluated by measuring the grade of erythema (by clinical examination and by erythema-directed digital photography), desquamation (by clinical examination), and pruritus (by subject-completed visual analog scale). Additionally, at the end of the protocol, a Physician Global Assessment was carried out. Results: Eighteen subjects completed the study, whereas two subjects were lost to follow-up for nonadherence and personal reasons, respectively. Day 7 data from target areas showed a significant reduction in erythema. At the end of study, a significant improvement was recorded for erythema, desquamation, and pruritus compared to baseline. Physician Global Assessment showed improvement in 89 percent of patients, with a complete response in 56 percent of cases. Conclusion: These preliminary results indicate that the study cream may be a viable nonprescription therapeutic option for patients affected by facial seborrheic dermatitis able to determine early and significant improvement. This study also emphasizes the advantages of using an erythema-directed digital photography system for assisting in a simple, more accurate erythema severity grading and therapeutic monitoring in patients affected by seborrheic dermatitis.

    To determine the effectiveness of salicylic acid chemical peeling in common dermatological conditions affecting face in people with predominant Fitzpatrick skin type IV and V. A total of 167 patients of either gender, aged between 13 to 60 years, having some facial dermatoses (melasma, acne vulgaris, postinflammatory hyperpigmentations, freckles, fine lines and wrinkles, post-inflammatory scars, actinic keratoses, and plane facial warts) were included. A series of eight weekly hospital based peeling sessions was conducted in all patients under standardized conditions with 30% salicylic acid. Clinical improvement in different disorders was evaluated by change in MASI score, decrease in the size of affected area and % reduction in lesions count. McNemar test was applied for data analysis. Majority of the patients showed moderate to excellent response. There was 35% to 63% improvement (p< 0.05) in all dermatoses. Significant side effects, as feared in Asian skins were not observed. Chemical peeling with salicylic acid is an effective and safe treatment modality in many superficial facial dermatoses. (author)

    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.

    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 Abstract Acne vulgaris is a common skin condition, one that is associated with significant psychological disability. The psychological impairments in acne include higher rates of depression, anxiety, anger and suicidal thoughts. Despite a paucity of clinical research, patients with skin conditions and/or mental health disorders are frequent consumers of dietary supplements. An overlap may exist between nutrients that potentially have both anti-acne and mood regulating properties; examples include omega-3 fatty acids from fish oil, chromium, zinc and selenium. Here we report on five cases of acne treated with eicosapentaenoic acid and antioxidant nutrients. Self-administration of these nutrients may have improved inflammatory acne lesions and global aspects of well-being; the observations suggest a need for controlled trials.

    Enlarged facial pores remain a common dermatologic and cosmetic concern from acne and rosacea, among other conditions, that is difficult to treat due to the multifactorial nature of their pathogenesis and negative impact on patients' quality of life. Enlarged facial pores are primarily treated through addressing associative factors, such as increased sebum production and cutaneous aging. We review the current treatment modalities for enlarged or dense facial pores, including topical retinoids, chemical peels, oral antiandrogens, and lasers and devices, with a focus on newer therapies.

    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 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.

    Full Text Available Background: Acne vulgaris is self-limiting, multifactorial disease involving sebaceous glands. 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

    To evaluate the prognostic and predictive value of electroneuronography (ENoG) in acute severe inflammatory facial paralysis, including Bell's palsy and Ramsay Hunt syndrome (RHS). Prospective observational study. Patients with acute severe facial paralysis of House-Brackmann (H-B) grade IV or worse and diagnosed with Bell's palsy or RHS were enrolled from August 2007 to July 2011. After treatment with oral corticosteroid, antiviral agent, and protective eye care, patients were followed up until recovery or 12 months from onset. Sixty-six patients with Bell's palsy and 22 with RHS were included. Multiple logistic regression analysis showed significant effect of ENoG value on recovery in both Bell's palsy and RHS. Values of ENoG were significantly worse in RHS than Bell's palsy. Chance of early recovery within 6 weeks after correction of ENoG effect was still significantly worse in RHS. Logistic regression analysis showed 90% chance of recovery within 6 months, expected with ENoG values of 69.2% degeneration (Bell's palsy) and 59.3% (RHS). The receiver operating characteristics (ROC) curves showed ENoG values of 82.5% (Bell's palsy) and 78.0% (RHS) as a critical cutoff value of nonrecovery until 1 year, with the best sensitivity and specificity. A higher chance of recovery was expected with better ENoG in Bell's palsy and RHS. Based on our data, nonrecovery is predicted in patients with ENoG value greater than 82.5% in Bell's palsy, and 78% in RHS. 4.

    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.

    2014-04-01

    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.

    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 Bodo C Melnik Department of Dermatology, Environmental Medicine and Health Theory, University of Osnabrück, Germany Abstract: Acne vulgaris, an epidemic inflammatory skin disease of adolescence, is closely related to Western diet. Three major food classes that promote acne are: 1 hyperglycemic carbohydrates, 2 milk and dairy products, 3 saturated fats including trans-fats and deficient ω-3 polyunsaturated fatty acids (PUFAs. Diet-induced insulin/insulin-like growth factor (IGF-1-signaling is superimposed on elevated IGF-1 levels during puberty, thereby unmasking the impact of aberrant nutrigenomics on sebaceous gland homeostasis. Western diet provides abundant branched-chain amino acids (BCAAs, glutamine, and palmitic acid. Insulin and IGF-1 suppress the activity of the metabolic transcription factor forkhead box O1 (FoxO1. Insulin, IGF-1, BCAAs, glutamine, and palmitate activate the nutrient-sensitive kinase mechanistic target of rapamycin complex 1 (mTORC1, the key regulator of anabolism and lipogenesis. FoxO1 is a negative coregulator of androgen receptor, peroxisome proliferator-activated receptor-γ (PPARγ, liver X receptor-α, and sterol response element binding protein-1c (SREBP-1c, crucial transcription factors of sebaceous lipogenesis. mTORC1 stimulates the expression of PPARγ and SREBP-1c, promoting sebum production. SREBP-1c upregulates stearoyl-CoA- and Δ6-desaturase, enhancing the proportion of monounsaturated fatty acids in sebum triglycerides. Diet-mediated aberrations in sebum quantity (hyperseborrhea and composition (dysseborrhea promote Propionibacterium acnes overgrowth and biofilm formation with overexpression of the virulence factor triglyceride lipase increasing follicular levels of free palmitate and oleate. Free palmitate functions as a “danger signal,” stimulating toll-like receptor-2-mediated inflammasome activation with interleukin-1β release, Th17 differentiation, and interleukin-17-mediated keratinocyte

    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.

    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.

    OBJECTIVE: Recurrent and chronic course of acne vulgaris, despite effect-proven therapies, point to an underfocused aspect in its pathogenesis and management. This study aims to assess in subjects with and without acne, the skin surface pH, a parameter that cumulatively represents functioning of various units of skin, including the barrier. METHODS: A total of 200 patients with acne and 200 age- and sex-matched controls were included. Under basal conditions, facial skin pH was derived from five sites using a skin pH-meter. The relation between skin pH and acne was evaluated according to sex. RESULTS: There were more subjects with normal skin pH in the control group compared to the case group, and the majority of acne occurrences in the case group were related to high skin pH ( p =0.000). Mean pH among cases was higher than normal reference value (pH 4.5-5.5 for women, 4-5.5 for men) and that of controls p (pH in either cases or controls ( p >0.05). CONCLUSION: Increased facial skin pH in patients with acne at basal conditions mirrors a chronic state of stratum corneum instability, which could be predisposing individuals to acne occurrence and/or recurrences. It could possibly be a common domain via which the classical pathomechanisms might be acting in acne. Integrating measures that maintain stratum corneum pH during therapy might prove worthwhile.

    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.

Three major food classes that promote acne are: 1) hyperglycemic carbohydrates, 2) milk and dairy products, 3) saturated fats including trans-fats and deficient ω-3 polyunsaturated fatty acids (PUFAs). Diet-induced insulin/insulin-like growth factor (IGF-1)-signaling is superimposed on elevated IGF-1 levels during puberty, thereby unmasking the impact of aberrant nutrigenomics on sebaceous gland homeostasis. Western diet provides abundant branched-chain amino acids (BCAAs), glutamine, and palmitic acid. Insulin and IGF-1 suppress the activity of the metabolic transcription factor forkhead box O1 (FoxO1). Insulin, IGF-1, BCAAs, glutamine, and palmitate activate the nutrient-sensitive kinase mechanistic target of rapamycin complex 1 (mTORC1), the key regulator of anabolism and lipogenesis. FoxO1 is a negative coregulator of androgen receptor, peroxisome proliferator-activated receptor-γ (PPARγ), liver X receptor-α, and sterol response element binding protein-1c (SREBP-1c), crucial transcription factors of sebaceous lipogenesis. mTORC1 stimulates the expression of PPARγ and SREBP-1c, promoting sebum production. SREBP-1c upregulates stearoyl-CoA- and Δ6-desaturase, enhancing the proportion of monounsaturated fatty acids in sebum triglycerides. Diet-mediated aberrations in sebum quantity (hyperseborrhea) and composition (dysseborrhea) promote Propionibacterium acnes overgrowth and biofilm formation with overexpression of the virulence factor triglyceride lipase increasing follicular levels of free palmitate and oleate. Free palmitate functions as a "danger signal," stimulating toll-like receptor-2-mediated inflammasome activation with interleukin-1β release, Th17 differentiation, and interleukin-17-mediated keratinocyte proliferation. Oleate stimulates P. acnes adhesion, keratinocyte proliferation, and comedogenesis via interleukin-1α release. Thus, diet

    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.

    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.

    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 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.

    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 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.

    Full Text Available Cathelicidins are a family of antimicrobial peptides acting as multifunctional effector molecules in innate immunity. Cathelicidin-BF has been purified from the snake venoms of Bungarus fasciatus and it is the first identified cathelicidin antimicrobial peptide in reptiles. In this study, cathelicidin-BF was found exerting strong antibacterial activities against Propionibacterium acnes. Its minimal inhibitory concentration against two strains of P. acnes was 4.7 µg/ml. Cathelicidin-BF also effectively killed other microorganisms including Staphylococcus epidermidis, which was possible pathogen for acne vulgaris. Cathelicidin-BF significantly inhibited pro-inflammatory factors secretion in human monocytic cells and P. acnes-induced O2.- production of human HaCaT keratinocyte cells. Observed by scanning electron microscopy, the surfaces of the treated pathogens underwent obvious morphological changes compared with the untreated controls, suggesting that this antimicrobial peptide exerts its action by disrupting membranes of microorganisms. The efficacy of cathelicidin-BF gel topical administering was evaluated in experimental mice skin colonization model. In vivo anti-inflammatory effects of cathelicidin-BF were confirmed by relieving P. acnes-induced mice ear swelling and granulomatous inflammation. The anti-inflammatory effects combined with potent antimicrobial activities and O2.- production inhibition activities of cathelicidin-BF indicate its potential as a novel therapeutic option for acne vulgaris.

    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.

    Oxidative stress plays a major role in acne formation; this suggests that oxygen-radical scavengers could be potential therapeutic agents. Fullerenol C60(OH)44, a recently developed polyhydroxylated fullerene, is a spherical carbon molecule that has many hydroxyl groups capable of potent radical-scavenging activity. We have investigated its inhibitory effects in vitro on sebum production in hamster sebocytes and in Propionibacterium acnes lipase activity. Sebum production was significantly reduced by 1.5 microM of fullerenol in cells that had been irradiated with 10 mJ/cm2 UVB, although it was not altered in the non-irradiated cells, indicating that fullerene is a sebum suppressor for sebocytes under oxidative stress, such as that induced by UVB. It was also found that fullerenol has inhibitory activity against P. acnes lipase. These results suggest that fullerenol could be a beneficial skin care reagent for controlling acne vulgaris by suppressing sebum in the inflammatory response and by reducing P. acnes lipase activity.

    Acne is a multifactorial dermatosis, which is influenced not only by hormones but also by the biochemical relationship between them and the pilosebaceous unit. Inflammatory cytokines, chemokines, active oxygen, and zinc are known to be associated with the development of acne. Further, steroid metabolism is known as one of the important factors related to sebum secretion and comedone formation in acne. However, there is a lack of studies comparing these human biomarkers between healthy individuals and patients with acne. In particular, no study has investigated the relationship between human biomarkers and patterns of acne yet.The purpose of this study is to investigate diagnostic human biomarkers in acne by comparing the biological and metabolic biomarkers between healthy individuals and patients with acne and identify the relationship between human biomarkers and patterns of acne.This study is a protocol for a cross-sectional study. Forty healthy participants and 60 patients with acne will be recruited at 1 center. We will collect their blood samples and analyze the molecular biological and metabolic biomarkers (cytokines, chemokines, reactive oxygen species, corticotropin-releasing hormone, zinc, amino acid, 1-carbon metabolite, lipid metabolite, etc.). Further, we will administer questionnaires regarding their diet, sleep, stress, and other factors relating to acne and measure their skin elasticity.The study protocol was approved by the Institutional Review Board of Oriental Medical Hospital at Kyung Hee Medical Center (KOMCIRB-161118-HR-062). Written informed consent will be obtained from all the participants. The trial was registered in the Clinical Research Information Service, Republic of Korea: KCT0002212.This trial will provide evidence regarding diagnostic human biomarkers in acne and the relationship between the human biomarkers and patterns of acne.

    Full Text Available Background: Facial schwannoma is a rare tumor arising from any part of the nerve. Probable symptoms are partial or facial weakness, hearing loss, visible mass in the ear, otorrhea, loss of taste, rarely pain, and sometimes without any symptoms. Patients should undergo a complete neurotologic history, examination with documentation of facial and auditory function, specially C.T. scan or M.R.I. Surgery is the only treatment option although the decision of when to remove facial schwannoma in the presence of normal facial function is difficult. Case: A 19-year-old girl with all above symptoms in the right side except loss of taste is diagnosed having facial schwannoma with full examination, audiometric, and radiological tests. She underwent surgery. In follow-up facial function were mostly restored. Conclusion: The need for careful assessment of patients with Bell's palsy cannot be overemphasized. In spite of the negative results if still there is any suspicoin, total facial nerve exploration is necessary.

    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.

    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.

    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

    Full Text Available Background: Acne vulgaris is a chronic inflammatory disease of the pilosebaceous units, which chiefly involves face and upper part of the trunk. Its prevalence is highest in adolescence, where the individual counters several psychosocial changes. Depression, suicidal thoughts, and low self esteem are reported in the patients with this disease. Aim: The goal of this study is to compare prevalence of anxiety and depression in the patients with acne vulgaris and normal population. Materials and Methods: In this cross-sectional study, 82 patients with acne vulgaris and 82 persons without acne who referred to a dermatology clinic and a specialized office for skin diseases in Rasht were studied. Anxiety and depression were evaluated by Hospital Anxiety and Depression Scale (HADS questionnaire and severity of acne was evaluated by Global Acne Grading System (GAGS. Data were analyzed by SPSS ver. 14.0 software, independent T-test, multi variate analysis of covariance (MANCOVA and chi-square test for comparison the quantitative and ordinal data, respectively; with α=0.05. Results: Prevalence of anxiety and mean of anxiety scores were 68.3% and 9.17 ± 3.52, respectively, in patients group and 39.1% and 7.10 ± 3.07, respectively, in control group in which there was a significant difference (P = 0.001. Prevalence of depression and mean of depression scores were 25.6% and 5.34 ± 3.29, respectively, in patients group and 28.1% and 5.01 ± 3.32, respectively, in control group in which there was no significant difference. Conclusion: According to high prevalence of anxiety in patients with acne vulgaris, assessment of the screening mental status of the patients by simple questionnaire such as HADS is suggested.

    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.

    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.

    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...

    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.

    The purpose of this study was to compare the clinical characteristics of acne in adult women in France and in sub-Saharan Africa. Women aged 25 years and over consulting for acne in hospital dermatology departments in Créteil, Dakar and Bamako were included. The data collected concerned a health questionnaire, previous history of acne, clinical examination and use of skin lighteners. Patient characteristics were expressed as absolute numbers and percentages for qualitative variables and as means and standard deviations or medians, and first and third quartiles, for quantitative variables based on distribution. There was no significant difference between the groups in terms of body mass index, tobacco smoking, age at first period and use of contraceptives. The presence of a lozenge-shaped area of abdominal hyperpilosity was more common in women of dark phototype, with no other signs of hyperandrogenism being seen. Acne was more severe in Dakar and in Bamako than in Créteil. Post-inflammatory pigmentation and involvement of the cheeks and forehead occurred significantly more frequently in patients of dark phototype. Involvement of the chin was more common in light-skinned subjects. While none of the women not of African origin performed voluntary skin lightening, this practice was recorded in half of women of African origin in Créteil and in Africa. This study shows clinical differences in acne in adult women according to phototype and geographical zone. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    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.

    The aim of this study is to retrospectively analyze the incidence of facial fractures along with age, gender predilection, etiology, commonest site, associated dental injuries, and any complications of patients operated in Craniofacial Unit of SDM College of Dental Sciences and Hospital. This retrospective study was conducted at the Department of OMFS, SDM College of Dental Sciences, Dharwad from January 2003 to December 2013. Data were recorded for the cause of injury, age and gender distribution, frequency and type of injury, localization and frequency of soft tissue injuries, dentoalveolar trauma, facial bone fractures, complications, concomitant injuries, and different treatment protocols.All the data were analyzed using statistical analysis that is chi-squared test. A total of 1146 patients reported at our unit with facial fractures during these 10 years. Males accounted for a higher frequency of facial fractures (88.8%). Mandible was the commonest bone to be fractured among all the facial bones (71.2%). Maxillary central incisors were the most common teeth to be injured (33.8%) and avulsion was the most common type of injury (44.6%). Commonest postoperative complication was plate infection (11%) leading to plate removal. Other injuries associated with facial fractures were rib fractures, head injuries, upper and lower limb fractures, etc., among these rib fractures were seen most frequently (21.6%). This study was performed to compare the different etiologic factors leading to diverse facial fracture patterns. By statistical analysis of this record the authors come to know about the relationship of facial fractures with gender, age, associated comorbidities, etc.

    Deep partial and full thickness facial burns require early skin grafting. Pressure face masks and local steroids reduce hypertrophic scarring. Split skin and Z-plasties are used for early reconstructive surgery. Only after softening of the scar tissue definite reconstructive work should be undertaken. For this period full thickness skin grafts and local flaps are preferred. Special regional problems require skilled plastic surgery. Reconstructive surgery is the most essential part of the rehabilitation of severe facial burns.

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.

    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.

    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 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.

    Full Text Available Blindsight denotes unconscious residual visual capacities in the context of an inability to consciously recollect or identify visual information. It has been described for color and shape discrimination, movement or facial emotion recognition. The present study investigates a patient suffering from cortical blindness whilst maintaining select residual abilities in face detection. Our patient presented the capacity to distinguish between jumbled/normal faces, known/unknown faces or famous people’s categories although he failed to explicitly recognize or describe them. Conversely, performance was at chance level when asked to categorize non-facial stimuli. Our results provide clinical evidence for the notion that some aspects of facial processing can occur without perceptual awareness, possibly using direct tracts from the thalamus to associative visual cortex, bypassing the primary visual cortex.

    Full Text Available El envejecimiento facial es un proceso único y particular a cada individuo y está regido en especial por su carga genética. El lifting facial es una compleja técnica desarrollada en nuestra especialidad desde principios de siglo, para revertir los principales signos de este proceso. Los factores secundarios que gravitan en el envejecimiento facial son múltiples y por ello las ritidectomías o lifting cérvico faciales descritas han buscado corregir los cambios fisonómicos del envejecimiento excursionando, como se describe, en todos los planos tisulares involucrados. Esta cirugía por lo tanto, exige conocimiento cabal de la anatomía quirúrgica, pericia y experiencia para reducir las complicaciones, estigmas quirúrgicos y revisiones secundarias. La ridectomía facial ha evolucionado hacia un procedimiento más simple, de incisiones más cortas y disecciones menos extensas. Las suspensiones musculares han variado en su ejecución y los vectores de montaje y resección cutánea son cruciales en los resultados estéticos de la cirugía cérvico facial. Hoy estos vectores son de tracción más vertical. La corrección de la flaccidez va acompañada de un interés en reponer el volumen de la superficie del rostro, en especial el tercio medio. Las técnicas quirúrgicas de rejuvenecimiento, en especial el lifting facial, exigen una planificación para cada paciente. Las técnicas adjuntas al lifting, como blefaroplastias, mentoplastía, lipoaspiración de cuello, implantes faciales y otras, también han tenido una positiva evolución hacia la reducción de riesgos y mejor éxito estético.

    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.

    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.

    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.

    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.

This pilot investigation aimed to evaluate the real-life tolerability, potential for comedogenicity and covering effect provided by this FCC.Methods: This single-center study evaluated the FCC applied once daily for 28 days in 20 females with facial acne. Tolerability was assessed by rating skin reactions on a scale from 1 =absent to 4 =evident. Comedogenicity potential was evaluated by determining the number of facial acne lesions before and after use of the FCC. The covering effect was rated in ten patients 30 minutes after application on a scale from 1 =none to 5 =excellent. Patients rated their opinions on the FCC on day 28 using a questionnaire.Results: Assessment of tolerability on days 0, 14, and 28 showed that skin reactions, including erythema, edema, dryness, desquamation, tight feeling, itching, and burning, were absent in all patients. The FCC was noncomedogenic and provided a significant 15.8% reduction in facial acne lesions after 28 days (P<0.001. The FCC provided a good covering effect 30 minutes after application in 80% of patients. All patients (100% were satisfied with the FCC, with 90% agreeing that the FCC was effective and 80% stating that the FCC improved their skin.Conclusion: The FCC was positively perceived, well tolerated, noncomedogenic, and provided an effective covering of acne in this small group of female patients with 1 month of follow-up.

  5. 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.

    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.

    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.

    There is a spectrum of musculoskeletal disorders which can be associated with dermatologic findings, the fundamental component of which is a nonbacterial osteitis. CRMO (Chronic recurrent multifocal osteomyelitis) and SAPHO syndrome (Synovitis, Acne, Pustulosis, Hyperostosis and Osteitis) describe paediatric and adult conditions, respectively, of inflammatory osteitis that can be associated with palmoplantar pustulosis and acne. Imaging findings are similar and a key component to the diagnosis in both conditions. This report describes two patients with strikingly similar radiologic presentations of clavicular osteitis in whom the diagnosis was made predominantly on the basis of imaging findings. The typical imaging features and radiographic hallmarks of both conditions will also be discussed.

This is the first study from Nigeria designed to address this issue. A total of 174 facial acne sufferers completed a self-administered questionnaire, which contained several items mentioning different areas in their belief, knowledge, perception, severity, socio-psychological impact and medication attention. The findings were discussed and compared to those of the Caucasians. The occurrence of the disorder was higher in females (65.0% compared to the males (35.0%. About 54.0% of the female subjects indicated increase in severity of the disorder during their pre-menstrual period. Also 64.9% of acne sufferers indicated increase in severity during the rainy season, while 93.1% of the population implicated stress to perpetuate the severity of the disorder. Most (75.7% of the acne sufferers believed that it is caused by oily diet, 40.8% thought that it is hereditary, while barely 5.2% had at sometime sought doctor's attention. Non- prescription products used by acne sufferers were cleansers and cream/lotions. Psychological abnormalities experienced by the sufferers included social inhibition, depression and anxiety. Pain and discomfort are the psychosomatic symptoms. No major differences were found in the beliefs, misconception and socio-psychological impact of acne sufferers in a black population (Nigeria compared to the Caucasians. There is need to improve the understanding of the disorder in Nigeria through health education programmes

    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.

Topical retinoids were the most prescribed drugs, and systemic medication was prescribed to 53.4% of the patients. Total regression was observed in 31 patients (26.7% within 12 weeks of treatment. Adverse reactions to topical treatment occurred in 21.5% of the patients. CONCLUSION: The clinical manifestations of AFA in patients without hyperandrogenism are moderate, with predominance of inflammatory lesions. Treatment is similar to that of acne vulgaris; however, special attention should be taken with more irritating medication since this group appears to be more predisposed to skin irritations.

    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 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.

Aim: To confirm that BGM (bakuchiol, Ginkgo biloba extract, and mannitol complex increases the established clinical efficacy of adapalene 0.1% gel in patients with acne. Methods: A clinical trial was conducted in acne patients. A total of 111 subjects received adapalene 0.1% gel and BGM complex or vehicle cream for 2 months. Assessments comprised Investigator Global Assessment (IGA, global efficacy, seborrhea intensity, inflammatory and non-inflammatory lesions, and subject perception, as well as overall safety and local tolerance and quality of life. Results: At the end of the trial, inflammatory and non-inflammatory lesions, IGA, global efficacy, and seborrhea intensity had significantly improved in both treatment groups. Differences were statistically significant (P<0.05 in favor of BGM complex for inflammatory lesions as well as IGA and seborrhea intensity. Global efficacy assessments and subject perception confirmed the superiority of BGM complex-including treatment over the comparative combination. Quality of life had improved more with the active combination than with the vehicle combination. In the active group, four subjects had to interrupt temporarily BGM complex and 12 adapalene compared to seven subjects interrupting the vehicle and eleven adapalene in the vehicle group. One subject withdrew from the trial due to an allergy to adapalene. The majority of all events were mild. Conclusion: BGM complex improves the treatment outcome of adapalene 0.1% gel in patients with acne vulgaris. Overall, safety and local tolerance of BGM complex were good.

    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.

    Autoinflammatory disorders are a group of Mendelian disorders characterized by seemingly unprovoked inflammatory bouts without high-titer autoantibodies or antigen-specific T-cells and are probably due to defects in the innate immunity. We here report on a 4-year-old Arabic boy with the clinical presentation of an autoinflammatory disorder, namely Pyogenic Arthritis, Pyoderma Gangrenosum and Acne (PAPA) syndrome. The presentation includes abscess formation after immunization and recurrent mono-articular acute arthritis in various joints that responded favourably to systemic glucocorticosteroids, albeit without acne or pyoderma gangrenosum. The mutation analysis of the boy identified a novel de novo mutation in PSTPIP1, the gene responsible for PAPA syndrome. We recommend that the diagnosis of PAPA syndrome should be entertained in the differential diagnosis of patients with recurrent sterile pyogenic arthritis prior to the development of pyoderma gangrenosum or acne in order to initiate a timely management of the disorder.

    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.

    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.

    The presence of sebum on the face is responsible for both facial shine and the formation of comedonal and inflammatory acne lesions. Sebum control is a goal of many OTC skin care products; however, most currently available products function by absorbing sebum from the face rather than modulating its production. To demonstrate the effect of topical 2% niacinamide on sebum excretion rates and casual sebum production in Oriental and Caucasian populations. Separate clinical trials were conducted in both Japan and the USA to evaluate the effect of topical 2% niacinamide in different ethnic groups. A total of 100 Japanese subjects were enrolled in a double-blind, placebo-controlled comparison between two independent balanced groups. Fifty subjects applied the 2% niacinamide moisturizer to the face for 4 weeks and 50 subjects used a placebo moisturizer for 4 weeks, with sebum excretion rate (SER) measurements taken at baseline, week 2, and week 4. In addition, 30 Caucasian subjects were enrolled in a randomized split-face study for 6 weeks with SER and casual sebum levels (CSL) measured at baseline, week 3, and week 6. The results of the Japanese study demonstrated that the SER of the two groups was not significantly different at baseline, but the 2% niacinamide treated group demonstrated significantly lowered SER after 2 and 4 weeks of application. The results were somewhat different in the Caucasian study. After 6 weeks of treatment, the CSL was significantly reduced, but the SER was not significantly reduced. Topical 2% niacinamide may be effective in lowering the SER in Japanese individuals and CSL in Caucasian individuals.

    Acne vulgaris is a ubiquitous problem affecting 80 percent of people ages 11 to 30 years, with many patients experiencing some degree of scarring. This review focuses on atrophic scars, the most common type of acne scar. We briefly address the cellular sequelae that lead to scar formation and the initial evaluation of patients with acne scars. We then discuss an algorithmic approach to the treatment of acne scarring based on the classification of scars into erythematous and atrophic types. Lastly, we discuss the future treatment of acne scars and ongoing clinical trials. PMID:29344322

    We hypothesized that the prevalence of Propionibacterium acnes in patients undergoing primary shoulder arthroscopy is equal in the glenohumeral space compared with the subacromial space. Patients aged 18 years or older with shoulder arthroscopies were included. The exclusion criteria were prior shoulder operations, complete rotator cuff tears, systemic inflammatory diseases, tumors, shoulder injections within 6 months of surgery, and antibiotic therapy within 14 days preoperatively. After standardized skin disinfection with Kodan Tinktur Forte Gefärbt, a skin swab was taken at the posterior portal. Arthroscopy was performed without cannulas, prospectively randomized to start either in the glenohumeral space or in the subacromial space, with direct harvesting of a soft-tissue biopsy specimen. Sample cultivation was conducted according to standardized criteria for bone and joint aspirate samples and incubated for 14 days. Matrix-assisted laser desorption-ionization time-of-flight spectrometry was used for specimen identification in positive culture results. The study prospectively included 115 consecutive patients with normal C-reactive protein levels prior to surgery (54.8% men; mean age, 47.2 ± 14.6 years). P acnes was detected on the skin after disinfection in 36.5% of patients, in the glenohumeral space in 18.9%, and in the subacromial space in 3.5% (P = .016). The prevalence of P acnes is significantly higher in the glenohumeral space compared with the subacromial space in primary shoulder arthroscopies. The results do not confirm the contamination theory but also cannot clarify whether P acnes is a commensal or enters the joint hematologically or even lymphatically or via an unknown pathway. Despite standardized surgical skin disinfection, P acnes can be detected in skin swab samples in more than one-third of patients.

    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.

    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

    Current clinical and microbiological information on acne fail to demonstrate a clear association between particular species, including Propionibacterium acnes, and disease, and the disease continues to be a considerable problem. To test if acne is associated with hitherto uncultured bacteria...... residing in diseased skin follicles, sequencing and phylogenetic analysis of approximately 5,700 amplified and cloned 16S rRNA genes were used to determine the microbial diversity in follicles from acne patients and healthy individuals and from superficial skin of acne patients. Follicles from healthy skin...... were exclusively colonized by P. acnes, whereas the follicular microbiota of acne patients, in addition, included S. epidermidis and minor proportions of other species. In comparison, samples from superficial skin showed a complex microbiota with 12 to 16 bacterial species represented. The study...

    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. Myrtacine® inhibited keratinocyte proliferation by 27 % and 76 % at 1 and 3 µg/mL, respectively (p P. ACNES strains growth with MICs of 4.9 µg/mL and 2.4 µg/mL, respectively.

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.

    Acne vulgaris is a chronic inflammatory disease affecting the pilosebaceous unit in the skin. Isotretinoin is a synthetic vitamin A derivative regarded as the most effective agent in the treatment of acne. There have recently been increasing reports of adverse effects of isotretinoin on the skeletal system. Our aim in this study was to evaluate the rheumatic side-effects triggered by this drug, and particularly the prevalence of sacroiliitis. A total of 73 patients receiving isotretinoin due to moderate or severe acne vulgaris were included. All patients were questioned about inflammatory low back pain and musculoskeletal pains during the treatment process. Inflammatory low back pain was evaluated using Assessment of Spondyloarthritis International Society (ASAS) criteria. Patients meeting ASAS criteria were evaluated with radiography and when necessary with sacroiliac magnetic resonance. The dose range for isotretinoin was between 0.4 and 0.8 mg/kg/day (mean 0.53 mg/kg/day). Treatment lasted for 6-8 months (mean 6.8 months). Lethargy was determined in 37 (50.7%) patients, myalgia in 31 (42.5%) and low back pain in 36 (49.3%). Mechanical low back pain symptoms were present in 20 of the patients describing low back pain and inflammatory low back pain in 16. Acute sacroiliitis was determined in six patients (8.2%) following a sacroiliac magnetic resonance imaging (MRI). Five (83.3%) of the patients with sacroiliitis were female and one (16.7%) was male. No statistically significant difference was determined between male and female patients in terms of prevalence of sacroiliitis (p = 0.392). The incidence of sacroiliitis in patients using isotretinoin is quite high. Patients using isotretinoin must be questioned about sacroiliitis findings and must be subjected to advanced assessment when necessary. Further studies regarding the development of sacroiliitis under isotretinoin therapy are now needed.

    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.

    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.

    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.

    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

    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.

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.

    Full Text Available A 23 year old female diagnosed as acne vulgaris underwent Therapeutic fasting (TF and other naturopathy and yoga modalities for 30 days. She presented with eruptions all over her face and the face was edematous. She was given a modified diet for initial 3 days which included fresh fruits and juices along with cooked vegetables and sorghum roti. Additionally Naturopathy treatments like Swedish massage, steam bath, warm water enema and hip bath were given along with some yogic postures, pranayam and kriyas (Cleansing procedures. The patient responded well to the therapeutic fasting. By the end of 30 days there were no eruptions in her face and her skin also was clear. All the treatments were based on the principle of naturopathic medicine that the body has its own power to heal itself. TF has shown to attenuate inflammatory status of the body by suppressing pro-inflammatory cytokine expression and decreasing body fat and circulating levels of leukocytes. This is the first study to report the non pharmacological approach towards treating acne. To conclude fasting along with other naturopathy and yoga modalities has shown noteworthy changes in reducing the inflammatory response in acne vulgaris. However large scale studies are warranted.

    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.

    2012-01-01

    Though fractional lasers are widely used for acne scars, very little clinical or histological data based on the objective clinical assessment or the depth of penetration of lasers on in vivo facial tissue are available. The depth probably is the most important aspect that predicts the improvement in acne scars but the studies on histology have little uniformity in terms of substrate (tissue) used, processing and stains used. The variability of the laser setting (dose, pulses and density) makes comparison of the studies difficult. It is easier to compare the end results, histological depth and clinical results. We analysed all the published clinical and histological studies on fractional lasers in acne scars and analysed the data, both clinical and histological, by statistical software to decipher their significance. On statistical analysis, the depth was found to be variable with the 1550-nm lasers achieving a depth of 679 μm versus 10,600 nm (895 μm) and 2940 nm (837 μm) lasers. The mean depth of penetration (in μm) in relation to the energy used, in millijoules (mj), varies depending on the laser studied. This was statistically found to be 12.9–28.5 for Er:glass, 3–54.38 for Er:YAG and 6.28–53.66 for CO2. The subjective clinical improvement was a modest 46%. The lack of objective evaluation of clinical improvement and scar-specific assessment with the lack of appropriate in vivo studies is a case for combining conventional modalities like subcision, punch excision and needling with fractional lasers to achieve optimal results.

    2013-01-01

    Full Text Available The main objective of the facial edema evaluation is providing the needed information to determine the effectiveness of the anti-inflammatory drugs in development. This paper presents a system that measures the four main variables present in facial edemas: trismus, blush (coloration, temperature, and inflammation. Measurements are obtained by using image processing and the combination of different devices such as a projector, a PC, a digital camera, a thermographic camera, and a cephalostat. Data analysis and processing are performed using MATLAB. Facial inflammation is measured by comparing three-dimensional reconstructions of inflammatory variations using the fringe projection technique. Trismus is measured by converting pixels to centimeters in a digitally obtained image of an open mouth. Blushing changes are measured by obtaining and comparing the RGB histograms from facial edema images at different times. Finally, temperature changes are measured using a thermographic camera. Some tests using controlled measurements of every variable are presented in this paper. The results allow evaluating the measurement system before its use in a real test, using the pain model approved by the US Food and Drug Administration (FDA, which consists in extracting the third molar to generate the facial edema.

    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.

    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. There is a need for standardized methods for grading acne and assessing therapeutic effects. Copyright © 2014 John Wiley & Sons, Ltd.

    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.

    2014-06-01

    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.

    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.

    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.

    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 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

    Enlarged skin pores refer to conditions that present with visible topographic changes of skin surfaces. Although not a medical concern, enlarged pores are a cosmetic concern for a large number of individuals. Moreover, clear definition and possible causes of enlarged pores have not been elucidated. To review the possible causes and treatment options for skin pores. This article is based on a review of the medical literature and the authors' clinical experience in investigating and treating skin pores. There are 3 major clinical causes of enlarged facial pores, namely high sebum excretion, decreased elasticity around pores, and increased hair follicle volume. In addition, chronic recurrent acne, sex hormones, and skin care regimen can affect pore size. Given the different possible causes for enlarged pores, therapeutic modalities must be individualized for each patient. Potential factors that contribute to enlarged skin pores include excessive sebum, decreased elasticity around pores, and increased hair follicle volume. Because various factors cause enlarged facial pores, it might be useful to identify the underlying causes to be able to select the appropriate treatment.

    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.

    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.

    Full Text Available BACKGROUND: Acne inversa (AI; also designated as Hidradenitis suppurativa is a common chronic inflammatory skin disease, localized in the axillary, inguinal and perianal skin areas that causes painful, fistulating sinuses with malodorous purulence and scars. Several chronic inflammatory diseases are associated with the metabolic syndrome and its consequences including arteriosclerosis, coronary heart disease, myocardial infraction, and stroke. So far, the association of AI with systemic metabolic alterations is largely unexplored. METHODS AND FINDINGS: A hospital-based case-control study in 80 AI patients and 100 age- and sex-matched control participants was carried out. The prevalence of central obesity (odds ratio 5.88, hypertriglyceridemia (odds ratio 2.24, hypo-HDL-cholesterolemia (odds ratio 4.56, and hyperglycemia (odds ratio 4.09 in AI patients was significantly higher than in controls. Furthermore, the metabolic syndrome, previously defined as the presence of at least three of the five alterations listed above, was more common in those patients compared to controls (40.0% versus 13.0%; odds ratio 4.46, 95% confidence interval 2.02 to 9.96; P<0.001. AI patients with metabolic syndrome also had more pronounced metabolic alterations than controls with metabolic syndrome. Interestingly, there was no correlation between the severity or duration of the disease and the levels of respective parameters or the number of criteria defining the metabolic syndrome. Rather, the metabolic syndrome was observed in a disproportionately high percentage of young AI patients. CONCLUSIONS: This study shows for the first time that AI patients have a high prevalence of the metabolic syndrome and all of its criteria. It further suggests that the inflammation present in AI patients does not have a major impact on the development of metabolic alterations. Instead, evidence is given for a role of metabolic alterations in the development of AI. We recommend

  12. Facial paralysis as a result of severe cervico-facial necrotizing fasciitis

    Skin microbiome varies from person to person due to a combination of various factors, including age, biogeography, sex, cosmetics and genetics. Many skin disorders appear to be related to the resident microflora, yet databases of facial skin microbiome of many biogeographies, including Thai, are limited. Metagenomics derived B-RISA and 16S rRNA gene sequencing was utilized to identify the culture-independent bacterial diversity on Thai male faces (cheek and forehead areas). Skin samples were categorized (grouped) into (i) normal ( teenage.hea ) and (ii) acne-prone ( teenage.acn ) young adults, and normal (iii) middle-aged ( middle.hea ) and (iv) elderly ( elderly.hea ) adults. The 16S rRNA gene sequencing was successful as the sequencing depth had an estimated >98% genus coverage of the true community. The major diversity was found between the young and elderly adults in both cheek and forehead areas, followed by that between normal and acne young adults. Detection of representative characteristics indicated that bacteria from the order Rhizobiales, genera Sphingomonas and Pseudoalteromonas , distinguished the elderly.hea microbiota, along the clinical features of wrinkles and pores. Prediction of the metabolic potential revealed reduced metabolic pathways involved in replication and repair, nucleotide metabolism and genetic translation in the elderly.hea compared with that in the teenage.hea . For young adults, some unique compositions such as abundance of Propionibacterium acnes and Staphylococcus epidermidis , with a minor diversity between normal and acne skins, were detected. The metabolic potentials of the acne vs. normal young adults showed that teenage.acn was low in many cellular processes (e.g., cell motility and environmental adaptation), but high in carbohydrate metabolism, which could support acne growth. Moreover, comparison with the age-matched males from the US (Boulder, Colorado) to gain insight into the diversity across national biogeography

    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.

    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 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.

    Facial tics and spasms are socially incapacitating, but effective treatment is often available. The clinical picture is sufficient for distinguishing between the different diseases that cause this affliction.We describe three cases of patients with facial tics or spasms: one case of tics, which are familiar to many physicians; one case of blepharospasms; and one case of hemifacial spasms. We discuss the differential diagnosis and the treatment possibilities for facial tics and spasms. Early diagnosis and treatment is important, because of the associated social incapacitation. Botulin toxin should be considered as a treatment option for facial tics and a curative neurosurgical intervention should be considered for hemifacial spasms.

    Body dysmorphic disorder (BDD) is characterized by preoccupation with perceived flaws in one's own appearance. Several risk factors such as aesthetic perceptual sensitivity have been proposed to explain BDD's unique symptomatology. Although research on facial discrimination is limited so far, the few existing studies have produced mixed results. Thus, the purpose of this study was to further examine facial discrimination in BDD. We administered a facial discrimination paradigm, which allows to assess the ability to identify slight to strong facial changes (e.g., hair loss, acne) when presented with an original (unmodified) facial image, relative to a changed (modified) facial image. The experiment was administered in individuals with BDD, social anxiety disorder, obsessive-compulsive disorder, and mentally healthy controls (32 per group, respectively). Overall, groups did not differ with respect to their ability to correctly identify facial aberrations when presented with other people's faces. Our findings do not support the hypothesis of enhanced general aesthetic perceptual sensitivity in individuals with (vs. without) BDD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    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.

    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.

    Shah, Sejal K; Alexis, Andrew F

    2010-05-01

    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.

    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.

    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.

    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.

    Full Text Available Acnes vulgaris is a chronic inflammatory disease of sebaceous follicles caused by Propionibacterium acnes and Staphylococcus epidermidis.The antibacterial activity of Impatiens balsamina L. has been studied for many years. The aims of this study were to find out the antiacne effect from methanolic extract of stems and leaves of Impatiens balsamina L. that were formulated in gel. Simplicia were extracted using soxhlet technique using methanol as solvent. Extracts were then formulated in gel in three variations of HPMC 4000 and Carbopol 934 as gel base with ratio of 70:30 (F1, 50:50 (F2 and 30:70 (F3. The determination of antiacne effect was done using disc diffusion method. Evaluation of physical and chemical properties of those gels includes organoleptic examination, spreadability testing, adhesion testing and pH testing. Data were analyzed using R version 2.14.1 package R-commander. Determination results showed the diameter of inhibition zone from FI, FII and FIII for P.acnes were 6.46 ±0.15 mm; 12.16 ± 0.35 mm; 16.13 ± 0.35mm and for S.epidermidis were 14.5 ± 0.47 mm; 16.56 ± 0.651 mm; 17.13 ± 0.44mm. Analysis results showed that gel of FIII gave optimal antiacne effect, but significantly different from positive control (p<0,05. The evaluation of gel showed that they have homogeny texture, good spreadability and adhesion, as well as the pH compliance.

    To evaluate if nonprescription topical agents may provide positive outcomes in the management of mild-to-moderate facial seborrheic dermatitis by reducing inflammation and scale production through clinical evaluation and erythema-directed digital photography. Open-label, prospective, not-blinded, intra-patient, controlled, clinical trial (target area). Twenty adult subjects affected by mild-to-moderate facial seborrheic dermatitis were enrolled and instructed to apply the study cream two times daily, initially on a selected target area only for seven days. If the subject developed visible improvement, it was advised to extend the application to all facial affected area for 21 additional days. Efficacy was evaluated by measuring the grade of erythema (by clinical examination and by erythema-directed digital photography), desquamation (by clinical examination), and pruritus (by subject-completed visual analog scale). Additionally, at the end of the protocol, a Physician Global Assessment was carried out. Eighteen subjects completed the study, whereas two subjects were lost to follow-up for nonadherence and personal reasons, respectively. Day 7 data from target areas showed a significant reduction in erythema. At the end of study, a significant improvement was recorded for erythema, desquamation, and pruritus compared to baseline. Physician Global Assessment showed improvement in 89 percent of patients, with a complete response in 56 percent of cases. These preliminary results indicate that the study cream may be a viable nonprescription therapeutic option for patients affected by facial seborrheic dermatitis able to determine early and significant improvement. This study also emphasizes the advantages of using an erythema-directed digital photography system for assisting in a simple, more accurate erythema severity grading and therapeutic monitoring in patients affected by seborrheic dermatitis.

    Facial lipoatrophy is one of the most distressing manifestation for HIV patients. It can be stigmatizing, severely affecting quality of life and self-esteem, and it may result in reduced antiretroviral adherence. Several filling techniques have been proposed in facial wasting restoration, with different outcomes. The aim of this study is to present a triangular area that is useful to fill in facial wasting rehabilitation. Twenty-eight HIV patients rehabilitated for facial wasting were enrolled in this study. Sixteen were rehabilitated with a non-resorbable filler and twelve with structural fat graft harvested from lipohypertrophied areas. A photographic pre-operative and post-operative evaluation was performed by the patients and by two plastic surgeons who were "blinded." The filled area, in both patients rehabilitated with structural fat grafts or non-resorbable filler, was a triangular area of depression identified between the nasolabial fold, the malar arch, and the line that connects these two anatomical landmarks. The cosmetic result was evaluated after three months after the last filling procedure in the non-resorbable filler group and after three months post-surgery in the structural fat graft group. The mean patient satisfaction score was 8.7 as assessed with a visual analogue scale. The mean score for blinded evaluators was 7.6. In this study the authors describe a triangular area of the face, between the nasolabial fold, the malar arch, and the line that connects these two anatomical landmarks, where a good aesthetic facial restoration in HIV patients with facial wasting may be achieved regardless of which filling technique is used.

    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.

    Full Text Available Jonette Keri1,2, Michael Shiman11Department of Dermatology and Cutaneous Surgery, University of Miami Miller School of Medicine, Miami, FL, USA; 2Dermatology Service, Miami VA Hospital, FL, USAAbstract: Acne vulgaris is a common skin disorder that can affect individuals from childhood to adulthood, most often occurring in the teenage years. 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

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

    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 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.

    Laser resurfacing has beneficial effects for the treatment of several skin conditions. Recently, the pulsed Er:YAG laser has been shown to be a highly effective treatment for several kinds of pitted facial scars. The purpose of this study was to assess the efficacy and safety of pulsed Er:YAG laser skin resurfacing for pitted facial scars. Four patients with small pox scars, five patients with chicken pox scars, and 21 patients with acne scars were included in this study. All patients were skin type III and IV. All patients were instructed to use tretinoin cream 0.05% nightly for 2-4 weeks prior to the laser treatment. The pulsed Er:YAG laser with 2-mm handpiece at the setting of 500 mJ/pulse, 3.5-4.5 W was used. Two weeks after laser treatment, topical application of hydroquinone 4%, tretinoin 0.05%, and hydrocortisone 1% cream was recommended for 2-4 weeks. Facial photographs were obtained at baseline and 2-week intervals postoperatively with a 35-mm single lense reflex camera equipped with a lense mounted ring flash. The results of treatment were evaluated for the changes of skin texture and color at 2 weeks, 1 month, and 3 months. Three patients with acne scars agreed to skin biopsy. Three months after laser treatment, all patients with small pox and chicken pox scars were improved about 55%, and patients with acne scars were improved about 40% on average. Pulsed Er:YAG laser skin resurfacing is an effective and safe treatment for pitted facial scars.

    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.

    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

    To describe a highly quantitative facial function-measuring tool that yields accurate, objective measures of facial position in significantly less time than existing methods. Facial Assessment by Computer Evaluation (FACE) software was designed for facial analysis. Outputs report the static facial landmark positions and dynamic facial movements relevant in facial reanimation. Fifty individuals underwent facial movement analysis using Photoshop-based measurements and the new software; comparisons of agreement and efficiency were made. Comparisons were made between individuals with normal facial animation and patients with paralysis to gauge sensitivity to abnormal movements. Facial measurements were matched using FACE software and Photoshop-based measures at rest and during expressions. The automated assessments required significantly less time than Photoshop-based assessments.FACE measurements easily revealed differences between individuals with normal facial animation and patients with facial paralysis. FACE software produces accurate measurements of facial landmarks and facial movements and is sensitive to paralysis. Given its efficiency, it serves as a useful tool in the clinical setting for zonal facial movement analysis in comprehensive facial nerve rehabilitation programs.

    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.

    Full Text Available Acne is an inflammatory skin condition that develops in pilosebaceous follicles, affecting mainly the onset of puberty. Among the numerous chemicals with dermatological and cosmetic purpose, traded and prescribed, raw materials of mineral origin have been often sought in formulations aimed at treating and / or preventing acne. This work aimed at the development of cosmetic preparations including green clay and sensory analysis of the formulations. Four formulations containing 2.5 % to 5 % green clay, in the presence or absence of dimethicone were prepared. The rheological behavior of the samples was analyzed at time 0, 24 hours, 30 days, 60 days and 90 days, using a cone and plate type rheometer (DVII + viscometer, Brookfiel. Sensory analyses of the formulations were also made. It can be concluded that all formulations exhibited pseudoplastic behavior and, through statistical analysis, it was found that there were no significant differences in acceptance between the formulations with or without dimethicone in the attributes of spreadability, stickiness, color and sensation after application. However, in regard to the attribute of odor, it was found that there was a greater acceptance in formulations to which dimethicone was added.

    Blue and red light have been reported to have beneficial effects on acne. However, there has been no double-blind, randomized study of acne treatment for combined blue and red light-emitting diode (LED) devices, and the associated molecular mechanisms have rarely been investigated. To evaluate the efficacy, safety and histological changes of combined blue and red LED phototherapy for acne vulgaris. Thirty-five patients with mild-to-moderate acne were randomly assigned to either a home-use irradiation group using an LED device, or a control group using a sham device. The treatment group was instructed to serially irradiate their forehead and cheeks with 420-nm blue light and 660-nm red light for 2.5 min twice daily for 4 weeks. At the final visit at 12 weeks, both inflammatory and noninflammatory acne lesions had decreased significantly, by 77% and 54%, respectively, in the treatment group. No significant difference was observed in the control group. In the treatment group, sebum output reduction, attenuated inflammatory cell infiltrations and a decreased size of the sebaceous gland were found. The immunostaining intensities for interleukin (IL)-8, IL-1α, matrix metalloproteinase-9, toll-like receptor-2, nuclear factor-κB, insulin-like growth factor-1 receptor and sterol response element binding protein (SREBP)-1 were reduced concomitantly. Messenger RNA expression of SREBP-1c was also decreased. No severe adverse reactions were reported. This LED phototherapy was safe and effective for treating not only inflammatory but also noninflammatory acne lesions, with good compliance. The experimental results correlated well with clinical results, partly elucidating the related molecular mechanisms. © 2012 The Authors. BJD © 2012 British Association of Dermatologists.

    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

    Androgens and insulin may contribute to increased sebum production in the pathogenesis of acne vulgaris. We investigated the association between serum desnutrin levels and acne vulgaris in the pathogenesis of insulin resistance. 25 patients presenting with acne vulgaris and 25 control subjects participated in this study. Fasting blood glucose, triglycerides, LDL, VLDL, HDL, total cholesterol, insulin, C-peptide and thyroid function tests were measured. The homeostasis model assessment of insulin resistance (HOMA-IR) was used to calculate insulin resistance. Desnutrin levels were determined by enzyme-linked immunosorbent assay (ELISA) according to the manufacturer's protocol. Patients with acne vulgaris had a mean serum desnutrin level of (8.83 ± 1.13 μIU/mL), which was statistically significantly lower in the control group (10:58 ± 3.43 μIU/mL). In patients with acne vulgaris the serum glucose levels, insulin levels and HOMA-IR values (87.92 ± 7:46 mg/dL, 11.33 ± 5.93 μIU/mL, 2.49 ± 1.40, respectively) were significantly higher than the control group (77.36 ± 9.83 mg/dL, 5.82 ± 2.68 μIU/mL, 1.11 ± 0.51, respectively) (p = 0.01, pacne vulgaris, as a result of increased levels of serum glucose and insulin, the function of desnutrin was suppressed, perhaps contributing to insulin resistance.

    Despite major advances in the area of burn management, burn injury continues to be a leading cause of pediatric mortality and morbidity. Facial burns in particular are devastating to the affected child and result in numerous physical and psychosocial sequelae. Although many of the principles of adult burn management can be applied to a pediatric patient with facial burns, the surgeon must be cognizant of several important differences. Facial burns and subsequent scar formation can drastically affect the growth potential of a child's face. Structures such as the nose and teeth may become deformed due to abnormal external forces caused by contractures. Serious complications such as occlusion amblyopia and microstomia must be anticipated and urgently addressed to avert permanent consequences, whereas other reconstructive procedures can be delayed until scar maturation occurs. Furthermore, because young children are actively developing the concept of self, severe facial burns can alter a child's sense of identity and place the child at high risk for future emotional and psychologic disturbances. Surgical reconstruction of burn wounds should proceed only after thorough planning and may involve a variety of skin graft, flap, and tissue expansion techniques. The most favorable outcome is achieved when facial resurfacing is performed with respect to the aesthetic units of the face. Children with facial burns remain a considerable challenge to their caregivers, and these patients require long-term care by a multidisciplinary team of physicians and therapists to optimize functional, cosmetic, and psychosocial outcomes.

    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.

    Full Text Available Facial hemihypertrophy and facial hemiatrophy are rare developmental anomalies. These conditions are characterized by an asymmetric growth of one or more parts of the tissues on one side of the face. The facial asymmetry may be total or partial. The unilateral overgrowth of the mandible seen as the facial asymmetry occurs in case of the congenital mandibular hemihypertrophy, whereas, the facial or mandibular hemiatrophy results in the hallowing or depression on one side of face. The hormonal imbalance, chromosomal abnormalities, trauma, trophic malfunctions of cervical sympathetic nervous system are the factors which are considered to be attributed to the mandibular or facial asymmetry.

    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.

    Full Text Available The mechanisms of inflammation in acne are currently subject of intense investigation. This study focused on the activation of adaptive and innate immunity in clinically early visible inflamed acne lesions and was performed in two independent patient populations. Biopsies were collected from lesional and non-lesional skin of acne patients. Using Affymetrix Genechips, we observed significant elevation of the signature cytokines of the Th17 lineage in acne lesions compared to non-lesional skin. The increased expression of IL-17 was confirmed at the RNA and also protein level with real-time PCR (RT-PCR and Luminex technology. Cytokines involved in Th17 lineage differentiation (IL-1β, IL-6, TGF-β, IL23p19 were remarkably induced at the RNA level. In addition, proinflammatory cytokines and chemokines (TNF-α, IL-8, CSF2 and CCL20, Th1 markers (IL12p40, CXCR3, T-bet, IFN-γ, T regulatory cell markers (Foxp3, IL-10, TGF-β and IL-17 related antimicrobial peptides (S100A7, S100A9, lipocalin, hBD2, hBD3, hCAP18 were induced. Importantly, immunohistochemistry revealed significantly increased numbers of IL-17A positive T cells and CD83 dendritic cells in the acne lesions. In summary our results demonstrate the presence of IL-17A positive T cells and the activation of Th17-related cytokines in acne lesions, indicating that the Th17 pathway is activated and may play a pivotal role in the disease process, possibly offering new targets of therapy.

    Despite the growing popularity of platelet-rich plasma, existing evidence supporting its efficacy remains controversial due to the lack of large-scale studies and standardized protocols for preparation and application. This article reviews its use in facial rejuvenation, fat grafting, acne scarring, and androgenic alopecia. Emphasis is placed on comparing methods of platelet-rich plasma preparation and application across studies. A systematic review was performed for articles published between 2006 and 2015. All clinical studies and case reports that addressed platelet-rich plasma alone and/or in combination with fat grafting for facial rejuvenation, acne scarring, or androgenic alopecia were included. Of the 22 articles included in the analysis, seven studies used platelet-rich plasma alone for facial rejuvenation, seven in combination with fat grafting, two for treatment of acne scarring, and six for treatment of androgenic alopecia. Individual study procedures, means of evaluation, and significant results are summarized. Although the majority of studies in this review report positive results, significant variation exists in preparation protocols and in the number and frequency of clinical treatments. The majority of studies report positive results for all indications evaluated in this review, but the procedure is limited by the lack of a standardized method for preparation and application of platelet-rich plasma. The extent to which significant variability in platelet-rich plasma preparation and/or application methods may affect clinical outcomes is not completely clear. In the interim, we present a consolidation of platelet-rich plasma treatment techniques and outcomes currently in use to help guide physicians in their clinical practice.

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

    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

    Case-control studies to support the concept of acne cosmetica are lacking. To examine the association of post-adolescent acne with the use of cosmetics and cosmetic procedures. 910 post-adolescent patients with acne and an equal number of matched controls were studied for exposure to cosmetics and cosmetic procedures. A cumulative cosmetic exposure index was stratified into four quarters of increasing exposure. Comparison of different cumulative exposure categories with the lowest exposure category (multivariate analysis, logistic regression) showed that the odds ratios, which were always cosmetic exposure increased [odds ratios (95% confidence intervals): 0.679 (0.501-0.922), 0.355 (0.258-0.487), 0.307 (0.217-0.433)]. However, some individual cosmetics had odds ratios >1. Overall cosmetic use was negatively associated with post-adolescent acne. The term 'acne cosmetica' is appropriate in the sense that some cosmetics may cause acne.

    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.

    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.

    Severely disfiguring facial injuries can have a devastating impact on the patient's quality of life. During the past decade, vascularized facial allotransplantation has progressed from an experimental possibility to a clinical reality in the fields of disease, trauma, and congenital malformations. This technique may now be considered a viable option for repairing complex craniofacial defects for which the results of autologous reconstruction remain suboptimal. Vascularized facial allotransplantation permits optimal anatomical reconstruction and provides desired functional, esthetic, and psychosocial benefits that are far superior to those achieved with conventional methods. Along with dramatic improvements in their functional statuses, patients regain the ability to make facial expressions such as smiling and to perform various functions such as smelling, eating, drinking, and speaking. The ideas in the 1997 movie "Face/Off" have now been realized in the clinical field. The objective of this article is to introduce this new surgical field, provide a basis for examining the status of the field of face transplantation, and stimulate and enhance facial transplantation studies in Korea.

    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.

    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.

    To evaluate the ability of hypoglossal-facial nerve anastomosis to reanimate the face in patients with complete nuclear (central) facial nerve palsy. Retrospective case series. Tertiary academic medical center. Four patients with complete facial nerve paralysis due to lesions of the facial nucleus in the pons caused by hemorrhage due to arteriovenous or cavernous venous malformations, stroke, or injury after tumor resection. All patients underwent end-to-end hypoglossal-facial nerve anastomosis. Facial nerve function using the House-Brackmann (HB) scale and physical and social/well-being function using the facial disability index. The mean age of the patients was 53.3 years (range, 32-73). There were 3 female and 1 male patients. All patients had preoperative facial function HB VI/VI. With a minimum of 12 months' follow-up after end-to-end hypoglossal-facial anastomosis, 75% of patients regained function to HB grade III/VI, and 25% had HB grade IV/VI. Average facial disability index scores were 61.25 for physical function and 78 for social/well-being, comparable to results from complete hypoglossal-facial anastomosis after peripheral facial nerve palsy after acoustic neuroma resection. Patients with nuclear facial paralysis who undergo end-to-end hypoglossal-facial nerve anastomosis achieve similar degrees of reanimation compared with those with peripheral facial nerve palsies. This raises the intriguing possibility that reinnervation may also be of benefit in patients with the vastly more common facial dysfunction because of cortical stroke or injury.

    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.

    Facial nerve paralysis (FNP) is a loss of facial movement due to facial nerve damage, which will lead to significant physical pain and abnormal function in patients. Traditional FNP grading methods are solely based on clinician's judgment and are time-consuming and subjective. Hence, an accurate, quantitative and objective method of evaluating FNP is proposed for constructing a standard system, which will be an invaluable tool for clinicians who treat the patient with FNP. In this paper, we introduce a novel method for quantitative assessment of FNP which combines an effective facial landmark estimation (FLE) algorithm and facial asymmetrical feature (FAF) by processing facial movement image. The facial landmarks can be detected automatically and accurately using FLE. The FAF is based on the angle of key facial landmark connection and mirror degree of multiple regions on human face. Our method provides significant contribution as it describes the displacement of facial organ and the changes of facial organ exposure during performing facial movements. Experiments show that our method is effective, accurate and convenient in practice, which is beneficial to FNP diagnosis and personalized rehabilitation therapy for each patient.

PIFP is the current terminology for Atypical Facial Pain and is characterized by daily or near daily pain that is initially confined but may subsequently spread. Pain cannot be attributed to any pathological process, although traumatic neuropathic mechanisms are suspected. When present intraorally, PIFP has been termed 'Atypical Odontalgia', and this entity is discussed in a separate article in this special issue. PIFP is often a difficult but important differential diagnosis among chronic facial pain syndromes. Aim To summarize current knowledge on diagnostic criteria, differential diagnosis, pathophysiology and management of PIFP. Methods We present a narrative review reporting current literature and personal experience. Additionally, we discuss and differentiate the common differential diagnoses associated with PIFP including traumatic trigeminal neuropathies, regional myofascial pain, atypical neurovascular pains and atypical trigeminal neuropathic pains. Results and conclusion The underlying pathophysiology in PIFP is still enigmatic, however neuropathic mechanisms may be relevant. PIFP needs interdisciplinary collaboration to rule out and manage secondary causes, psychiatric comorbidities and other facial pain syndromes, particularly trigeminal neuralgia. Burden of disease and psychiatric comorbidity screening is recommended at an early stage of disease, and should be addressed in the management plan. Future research is needed to establish clear diagnostic criteria and treatment strategies based on clinical findings and individual pathophysiology.

    Bilateral facial paralysis is a rare clinical entity and presents as a diagnostic challenge. Unlike its unilateral counterpart facial diplegia is seldom secondary to Bell's palsy. Occurring at a frequency of 0.3% to 2% of all facial palsies it often indicates ominous medical conditions. Guillian-Barre syndrome needs to be considered as a differential in all given cases of facial diplegia where timely treatment would be rewarding. Here a case of bilateral facial palsy due to Guillian-Barre syndrome with atypical presentation is reported.

    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 visible skin disease commonly seen in adolescence. As it affects the appearance, it is likely to bring stress to the adolescent's life regarding sensitivity about their appearance. The aim of the study was to investigate the social anxiety level, acne-specific life quality, and self-esteem among adolescents with acne vulgaris. In addition, we evaluated the relationship between these parameters, clinical severity, and sociodemographic data. One hundred and two adolescents with acne vulgaris, aged 12-17 years without any psychiatric or medical comorbidity were recruited. The control group consisted of 83 adolescents in the same age range, who had neither psychiatric disease nor acne. Sociodemographic form (SDF), Capa Social Phobia Scale for Children and Adolescents (CSPSCA), and Rosenberg Self-esteem Scale (RSES) were applied to both groups. Additionally, the severity of acne was determined with Global Acne Grading System (GAGS), and life quality of the patients was evaluated with Acne Quality of Life Scale (AQOL). There was no significant difference in social anxiety levels and self-esteem between the study and control groups. Life quality impairment and high social anxiety levels, as well as low self-esteem, were found to be associated regardless of the clinical severity. Clinicians should be aware of the psychiatric comorbidities when treating adolescents with acne vulgaris. Especially, low self-esteem and life quality impairment should warn clinicians to predict high social anxiety levels in adolescent acne patients.

    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.

    While it is generally accepted that Propionibacterium acnes is involved in the development of acne, other bacteria including Staphylococcus epidermidis have also been isolated from the acne lesion. The interaction between Lactobacillus reuteri, a probiotic bacterium, and acnegenic bacteria is unclear. This study examined the effects of L. reuteri on the proliferation of P. acnes and S. epidermidis. Human-derived L. reuteri strains (KCTC 3594 and KCTC 3678) and rat-derived L. reuteri KCTC 3679 were used. All strains exhibited significant inhibitory effects on the growth of P. acnes and S. epidermidis. The proliferation of P. acnes was decreased by 2-log scales after incubation with L. reuteri for 24 h. In addition, the proliferation of S. epidermidis was decreased by 3-log scales after incubation with L. reuteri for 24 h, whereas the growth of L. reuteri was unaffected by P. acnes or S. epidermidis. Among the L. reuteri strains examined, L. reuteri KCTC 3679 had the strongest inhibitory effect on the growth of P. acnes and S. epidermidis, followed by L. reuteri KCTC 3594 and L. reuteri KCTC 3678. Interestingly, reuterin, an antimicrobial factor, was produced only by L. reuteri KCTC 3594. The most pronounced the antibacterial activities of L. reuteri were attributed to the production of organic acids. Overall, these results suggest that L. reuteri may be a useful probiotic agent to control the growth of bacteria involved in acne inflammation and prevent acne.

  16. Etiologic Aspect of Sarcoidosis as an Allergic Endogenous Infection Caused by Propionibacterium acnes

    Full Text Available Sarcoidosis is a systemic granulomatous disease of unknown etiology. Propionibacterium acnes is the only microorganism that has been isolated from sarcoid lesions. Many P. acnes have been detected in sarcoid lymph nodes using quantitative PCR and in sarcoid granulomas by in situ hybridization. P. acnes trigger factor protein causes a cellular immune response only in sarcoid patients and induces pulmonary granulomas in mice sensitized with the protein and adjuvant, but only those with latent P. acnes infection in their lungs. Eradication of P. acnes by antibiotics prevents the development of granulomas in this experimental model. Although P. acnes is the most common commensal bacterium in the lungs and lymph nodes, P. acnes-specific antibody detected the bacterium within sarcoid granulomas of these organs. P. acnes can cause latent infection in the lung and lymph node and persist in a cell-wall-deficient form. The dormant form is activated endogenously under certain conditions and proliferates at the site of latent infection. In patients with P. acnes hypersensitivity, granulomatous inflammation is triggered by intracellular proliferation of the bacterium. Proliferating bacteria may escape granulomatous isolation, spreading to other organs. Latent P. acnes infection in systemic organs can be reactivated by another triggering event, leading to systemic sarcoidosis.

    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

    AIM: The purpose of this study was to investigate the value of contrast-enhanced magnetic resonance (MR) imaging in patients with peripheral facial nerve palsy. MATERIALS AND METHODS: MR imaging was performed in 147 patients with facial nerve palsy, using a 1.0 T unit. All of 147 patients were evaluated by contrast-enhanced MR imaging and the pattern of enhancement was compared with that in 300 control subjects evaluated for suspected acoustic neurinoma. RESULTS: The intrameatal and labyrinthine segments of the normal facial nerve did not show enhancement, whereas enhancement of the distal intrameatal segment and the labyrinthine segment was respectively found in 67% and 43% of patients with Bell's palsy. The geniculate ganglion or the tympanic-mastoid segment was enhanced in 21% of normal controls versus 91% of patients with Bell's palsy. Abnormal enhancement of the non-paralyzed facial nerve was found in a patient with bilateral temporal bone fracture. CONCLUSION: Enhancement of the distal intrameatal and labyrinthine segments is specific for facial nerve palsy. Contrast-enhanced MR imaging can reveal inflammatory facial nerve lesions and traumatic nerve injury, including clinically silent damage in trauma. Kinoshita T. et al. (2001)

    The Cardiff Acne Disability Index was originally developed in English for measuring quality of life of acne patients. Considering the psychosocial impact of this disease, it is important to have instruments culturally and linguistically validated for use in Brazilian adolescents. To translate the Cardiff Acne Disability Index into Brazilian Portuguese, culturally adapt it, and verify its reliability and validity in adolescent patients with acne. In the first step, the Cardiff Acne Disability Index was translated and validated linguistically to Brazilian Portuguese in accordance with international guidelines published. In the second step, the validation of the Cardiff Acne Disability Index into Brazilian Portuguese instrument was performed, when patients aged from 12 to 20 years with acne were selected. The participants were interviewed to collect demographic data, submitted to the classification of acne by the Global Acne Grading System and invited to respond the Cardiff Acne Disability Index into Brazilian Portuguese version and DLQI (>16 years) or CDLQI (≤16 years). The internal consistency of Cardiff Acne Disability Index into Brazilian Portuguese was assessed by Cronbach's alpha coefficient and concurrent validity was measured by the Spearman correlation coefficient and Student 's t-test for paired samples. The study included 100 adolescents. The Cardiff Acne Disability Index into Brazilian Portuguese version showed good reliability and internal consistency (Cronbach's alpha = 0.73). The concurrent validity of the scale was supported by a strong and significant correlation with CDLQI / DLQI instruments (rs=0.802;pPortuguese version is a reliable, valid and valuable tool to measure the impact of acne on quality of life in adolescent 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. In 89 cases, P. acnes was cultured exclusively; in 30 cases, it was isolated in combination with other bacteria (primarily coagulase-negative Staphylococcus spp. Among positive specimens, the median P. acnes bacterial burden was 350 CFU/g (12 - ~20,000 CFU/g. Thirty-eight P. acnes isolates were subjected to molecular sub-typing, identifying 4 of 6 defined phylogroups: IA1, IB, IC, and II. Eight culture-positive specimens were evaluated by fluorescence microscopy and revealed P. acnes in situ. Notably, these bacteria demonstrated a biofilm distribution within the disc matrix. P. acnes bacteria were more prevalent in males than females (39% vs. 23%, p = 0.0013.This study confirms that P. acnes is prevalent in herniated disc tissue. Moreover, it provides the first visual

    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.

    The efficacy of facial muscle exercises (FMEs) for facial rejuvenation is controversial. In the majority of previous studies, nonquantitative assessment tools were used to assess the benefits of FMEs. This study examined the effectiveness of FMEs using a Pao (MTG, Nagoya, Japan) device to quantify facial rejuvenation. Fifty females were asked to perform FMEs using a Pao device for 30 seconds twice a day for 8 weeks. Facial muscle thickness and cross-sectional area were measured sonographically. Facial surface distance, surface area, and volumes were determined using a laser scanning system before and after FME. Facial muscle thickness, cross-sectional area, midfacial surface distances, jawline surface distance, and lower facial surface area and volume were compared bilaterally before and after FME using a paired Student t test. The cross-sectional areas of the zygomaticus major and digastric muscles increased significantly (right: P jawline surface distances (right: P = 0.004, left: P = 0.003) decreased significantly after FME using the Pao device. The lower facial surface areas (right: P = 0.005, left: P = 0.006) and volumes (right: P = 0.001, left: P = 0.002) were also significantly reduced after FME using the Pao device. FME using the Pao device can increase facial muscle thickness and cross-sectional area, thus contributing to facial rejuvenation. © 2018 The American Society for Aesthetic Plastic Surgery, Inc.

    Isotretinoin is a first generation retinoid with pleiotropic effects on keratinocyte differentiation, proliferation, and activity of sebaceous glands. For years, there has been intense debate on whether the use of isotretinoin combined with cosmetic or surgical procedures is safe and potentially more efficient than either therapy alone. Due to delays in wound healing and keloid formation, conservative recommendations were not to combine isotretinoin with any plastic surgery or local treatment at 6 to 12 months after discontinuation of the drug. However, there is increasing evidence that a combination approach is not only safe, but may also provide excellent cosmetic outcomes in acne scars, sebaceous gland hyperplasia, and thick-skinned patients undergoing facial plastic surgery. In particular, low-dose regimens of isotretinoin may offer advantages over standard dosage treatments because of better tolerability and safety in long-term use adjunct with surgical interventions. In this article, the authors aim to summarize the current evidence on the use of isotretinoin in facial plastic surgery and to share their experience from selected patients.

    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

    Full Text Available Context: Acne vulgaris (AV is a common disease affecting all ages and ethnic groups. Androgens, skin and serum lipids, inflammatory signaling and regulatory neuropeptides seem to be involved in this multi-factorial process. Aim: The aim of this work was to determine hormonal levels and lipid profile in non-obese, non-hirsute females with AV. Subjects and Methods: A total of 60 non-obese, non-hirsute female cases with different grades of AV and 60 age- and gender-matched healthy volunteers were included. Measurement of serum total and free testosterone, sex hormone binding globulin (SHBG, estradiol and progesterone and blood lipids was done during the luteal phase of the menstrual cycle. Results: Total testosterone, free testosterone (FT and progesterone levels were significantly higher (P < 0.001 for all while estradiol levels (P < 0.001 and SHBG (P < 0.01 were significantly lower in cases than controls. Total cholesterol and low density lipoprotein cholesterol (LDL-C levels were significantly higher (P < 0.001 for both while high density lipoprotein cholesterol (HDL-C and apolipoprotein A-1 (ApoA-1 levels were significantly lower (P < 0.001 for both in cases than controls. Higher values of FT (P = 0.03 and SHBG (P = 0.02 and lower values of estradiol (P = 0.04 levels were significantly in favor of severe acne. Higher values of cholesterol (P < 0.001 and LDL-C (P = 0.03 and lower values of HDL-C (P = 0.01 and ApoA-1 (P = 0.02 levels were significantly associated with severe acne. Conclusion: Changes in hormone levels and lipid profile in non-obese and non-hirsute females with AV should be considered in disease pathogenesis and in treatment prescription of these patients.

    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.

    Background: acne vulgaris, is one of the most common skin disorder. Previous studies about the role of smoke in the pathogenesis of acne reported contradictory results. The aim of this study was to conduct a case-control study investigating the relationship between tobacco smoking and acne.

    Methods: a case-control study was performed during the period September 2009 - February 2010. A questionnaire was administrated to each participant, to assess the association acne - smoke. Cases were outpatients of the Dermatologic Ambulatory of the “Fiorini” Hospital, Sapienza University of Rome (Italy. Controls were age and gender-matched to the cases. The ratio cases-controls was 1:2. A univariate and a multiple logistic regression analysis were conducted; Odds Ratio (OR and the relative 95% confidence interval (95%CI were assessed. The statistical significance was set at p < 0.05.

    Results: crude OR for the association acne - smoke was 7.26 (IC=2.27-23.18; adjusted OR for sex and age was 5.47 (IC=1.67-17.97. Of 93 cases, 6 had a severe grade of acne (6.5%, 19 had an intermediate grade of acne (20.4%, and 68 had a mild grade of acne (73.1%. No one of the smokers had a severe grade of acne, one had an intermediate grade of acne and 11 had mild acne; these differences are not statistically significant.

    Abstract 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 inflammat...

    Propionibacterium acnes is the predominant organism in acne lesions, but the sensitivity of different biotypes of P. acnes to therapeutic agents has seldom been reported. To characterize biotypes of P. acnes and to measure the effects of Keigai-rengyo-to (KRT) and minocycline (MINO) on clinical P. acnes isolates. Propionibacterium acnes biotype III (BIII) is the most common form of identified acne lesion, followed by P. acnes biotype I. BIII was isolated from mild, moderate and severe severity and the average lipase activity of BIII was higher than that of Biotypes I, II, IV and V. No significant differences in the decrease of free fatty acid production elicited by KRT or by MINO were found between BIII and the other biotypes. The degree of decreased butyric acid production was greater than that of propionic acid production in the medium supplemented with MINO. The percent decrease of butyric acid production elicited by 1 mg/mL of KRT was the same as that elicited by 0.1 microg/mL of MINO. Among biotypes of P. acnes, the minimal inhibitory concentrations of agents tested were generally higher in erythritol-positive biotypes than in erythritol-negative biotypes. The high frequency of BIII might be responsible for the severity of acne in patients. It seems that if the same concentrations of MINO and KRT are used, the antilipase activity of MINO is stronger than that of KRT. Minocycline also has a direct anti-lipase activity against P. acnes. The mechanism underlying the influence of erythritol on the susceptibility of P. acnes to these agents remains unknown.

    Materials and methods: A sample of 120 patients (60 males and 60 females; mean age, 15 years; range, 16-22 years who had received orthodontic clinical examination at AME′s Dental College and Hospital were selected. Selection was made in such a way that following malocclusions with equal sexual distribution was possible from the patient database. Patients selected were classified into skeletal Class I (25 males and 25 females, Class II (25 males and 25 females and Class III (10 males and 10 females based on ANB angle. The number was predecided to be the same and also was based on the number of patients with following malocclusions reported to the department. Differences in length between distances from the points at which ear rods were inserted to the facial midline and the perpendicular distance from the softtissue menton to the facial midline were measured on a frontofacial photograph. Subjects with a discrepancy of more than three standard deviations of the measurement error were categorized as having left- or right-sided laterality. Results: Of subjects with facial asymmetry, 74.1% had a wider right hemiface, and 51.6% of those with chin deviation had left-sided laterality. These tendencies were independent of sex or skeletal jaw relationships. Conclusion: These results suggest that laterality in the normal asymmetry of the face, which is consistently found in humans, is likely to be a hereditary rather than an acquired trait.

    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

    Investigation of the human microbiome has revealed diverse and complex microbial communities at distinct anatomic sites. The microbiome of the human sebaceous follicle provides a tractable model in which to study its dominant bacterial inhabitant, Propionibacterium acnes, which is thought to contribute to the pathogenesis of the human disease acne. To explore the diversity of the bacteriophages that infect P. acnes, 11 P. acnes phages were isolated from the sebaceous follicles of donors with healthy skin or acne and their genomes were sequenced. Comparative genomic analysis of the P. acnes phage population, which spans a 30-year temporal period and a broad geographic range, reveals striking similarity in terms of genome length, percent GC content, nucleotide identity (>85%), and gene content. This was unexpected, given the far-ranging diversity observed in virtually all other phage populations. Although the P. acnes phages display a broad host range against clinical isolates of P. acnes, two bacterial isolates were resistant to many of these phages. Moreover, the patterns of phage resistance correlate closely with the presence of clustered regularly interspaced short palindromic repeat elements in the bacteria that target a specific subset of phages, conferring a system of prokaryotic innate immunity. The limited diversity of the P. acnes bacteriophages, which may relate to the unique evolutionary constraints imposed by the lipid-rich anaerobic environment in which their bacterial hosts reside, points to the potential utility of phage-based antimicrobial therapy for acne. Propionibacterium acnes is a dominant member of the skin microflora and has also been implicated in the pathogenesis of acne; however, little is known about the bacteriophages that coexist with and infect this bacterium. Here we present the novel genome sequences of 11 P. acnes phages, thereby substantially increasing the amount of available genomic information about this phage population

    Abnormal hyperkeratinization in sebaceous hair follicles has long been believed to play an important role in acne pathogenesis. Several early reports purported to provide histological evidence for hyperproliferation of keratinocytes in acne lesions by showing a higher expression of the Ki67 as well as certain keratins. The evidence is, however, not robust and a number of methodological and technical pitfalls can be identified in these studies. In this study we looked at the expression of proliferation, mitosis and apoptosis markers directly at acne skin lesions in 66 patients with acne vulgaris. Ki67 was assessed using immunohistochemistry and ⍺-tubulin, phospho-histone H3 and cleaved-PARP with immunofluorescence microscopy. Allogenic unaffected hair follicles from the same acne patients were used as an internal control. In both acne and control hair follicles the α-tubulin staining was universal, approaching 100% cells and showed no signs of changed assembly. Expression of cleaved-PARP - the apoptosis marker was a rare event. Cell proliferation rate measured by the expression of Ki67 and phospho-histone H3 was virtually identical between acne and the two control groups. Our findings show the absence of increased keratinocyte proliferation in acne vulgaris. Alternative mechanisms are likely responsible for infundibular hyperkeratinization in acne pathogenesis.

    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.

    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.

    Acne vulgaris may be effectively treated with combination oral contraceptive pills (COCs) in women. COCs may be useful in any woman with acne in the absence of known contraindications. When prescribing a COC to a woman who also desires contraception, the risks of the COC are compared with the risks associated with pregnancy. When prescribing a COC to a woman who does not desire contraception, the risks of the COC must be weighed against the risks associated with acne. COCs may take 3 cycles of use to show an effect in acne lesion count reductions. Copyright © 2016 Elsevier Inc. All rights reserved.

    Acne vulgaris is a very common disease of the pilosebaceous unit of the human skin. The pathological processes of acne are not fully understood. To gain further insight sebaceous follicular casts were extracted from 18 healthy and 20 acne-affected individuals by cyanoacrylate-gel biopsies and further processed for mass spectrometry analysis, aiming at a proteomic analysis of the sebaceous follicular casts. Human as well as bacterial proteins were identified. Human proteins enriched in acne and normal samples were detected, respectively. Normal follicular casts are enriched in proteins such as prohibitins and peroxiredoxins which are involved in the protection from various stresses, including reactive oxygen species. By contrast, follicular casts extracted from acne-affected skin contained proteins involved in inflammation, wound healing and tissue remodeling. Among the most distinguishing proteins were myeloperoxidase, lactotransferrin, neutrophil elastase inhibitor and surprisingly, vimentin. The most significant biological process among all acne-enriched proteins was ‘response to a bacterium’. Identified bacterial proteins were exclusively from Propionibacterium acnes. The most abundant P. acnes proteins were surface-exposed dermatan sulphate adhesins, CAMP factors, and a so far uncharacterized lipase in follicular casts extracted from normal as well as acne-affected skin. This is a first proteomic study that identified human proteins together with proteins of the skin microbiota in sebaceous follicular casts. PMID:25238151

    Full Text Available Background Skin microbiome varies from person to person due to a combination of various factors, including age, biogeography, sex, cosmetics and genetics. Many skin disorders appear to be related to the resident microflora, yet databases of facial skin microbiome of many biogeographies, including Thai, are limited. Methods Metagenomics derived B-RISA and 16S rRNA gene sequencing was utilized to identify the culture-independent bacterial diversity on Thai male faces (cheek and forehead areas. Skin samples were categorized (grouped into (i normal (teenage.hea and (ii acne-prone (teenage.acn young adults, and normal (iii middle-aged (middle.hea and (iv elderly (elderly.hea adults. Results The 16S rRNA gene sequencing was successful as the sequencing depth had an estimated >98% genus coverage of the true community. The major diversity was found between the young and elderly adults in both cheek and forehead areas, followed by that between normal and acne young adults. Detection of representative characteristics indicated that bacteria from the order Rhizobiales, genera Sphingomonas and Pseudoalteromonas, distinguished the elderly.hea microbiota, along the clinical features of wrinkles and pores. Prediction of the metabolic potential revealed reduced metabolic pathways involved in replication and repair, nucleotide metabolism and genetic translation in the elderly.hea compared with that in the teenage.hea. For young adults, some unique compositions such as abundance of Propionibacterium acnes and Staphylococcus epidermidis, with a minor diversity between normal and acne skins, were detected. The metabolic potentials of the acne vs. normal young adults showed that teenage.acn was low in many cellular processes (e.g., cell motility and environmental adaptation, but high in carbohydrate metabolism, which could support acne growth. Moreover, comparison with the age-matched males from the US (Boulder, Colorado to gain insight into the diversity across

    Acne is common in adolescents and especially difficult to manage in people with color. A fixed combination of clindamycin phosphate and benzoyl peroxide (BPO) (clindamycin phosphate 1.2%/BPO 2.5% gel) was evaluated to determine its utility in treating moderate to severe acne in adolescents with skin of color. Three hundred thirty-seven adolescent acne subjects (aged 12 to color were evaluated from 2 multicenter, double-blind studies. Subjects were randomized to receive clindamycin phosphate 1.2%/BPO 2.5% gel or vehicle, once daily for 12 weeks. Efficacy and tolerability were evaluated. Data were compared with an adolescent (A) and skin of color (B) cohort from the same pivotal study enrolling 2,813 subjects. Superior mean percent reductions in inflammatory, noninflammatory, and total lesion counts were observed in subjects receiving clindamycin phosphate 1.2%/BPO 2.5% gel compared to vehicle. At week 12, clindamycin phosphate 1.2%/BPO 2.5% gel showed similar lesion reduction compared to groups A and B (Pvehicle and comparable to that seen in groups A and B (Pcolor.

    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.

    2014-10-01

    In recent years, the prevalence of adult female acne has increased, but the reason for this increase remains unclear. Acne is one of the most common skin disorders. It can be triggered or worsened by endogenous and exogenous factors, including genetic predisposition, hormone concentrations, diet, smoke and stress; although the interaction with this last factor is not well understood. Modern life presents many stresses including urban noises, socioeconomic pressures and light stimuli. Women are especially affected by stress during daily routine. The recent insertion in the labor market is added to the duties of the mother and wife. Women also have a higher risk of developing psychiatric disorders such as depression and anxiety. Sleep restriction is added to these factors, with several negative consequences on health, including on hormonal secretion and the immune system. This is further complicated by the natural variation in sleep architecture across the menstrual cycle. Recent studies have brought new data about the mechanisms and possible factors involved. This review aims to establish a connection between stress, sleep deprivation and adult female acne.

    treatment. Based on evidence from the published literature, patients treated with A-BPO/D would be expected to have an initial 72% reduction in inflammatory lesions, and patients treated with oral isotretinoin would have an 80% to 90% reduction of these lesions. The median weekly cost for the basic treatment model was $44 for A-BPO/D and $62 for oral isotretinoin. The weekly median costs for the long-term model were $44 for patients initially receiving a regimen of A-BPO/D followed by a maintenance regimen of A-BPO monotherapy and $50 for patients receiving an initial regimen of A-BPO/D who required a subsequent regimen of oral isotretinoin. The weekly cost for oral isotretinoin in the long-term model was $62. The comparison of these 2 treatments demonstrated that they are both effective in treating severe acne, and that A-BPO/D was less expensive weekly than oral isotretinoin. These models show that A-BPO/D is safer than and is a more cost-effective alternative to oral isotretinoin for treating patients with severe acne vulgaris.

    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.

    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.

    Antibiotics are widely applied in management of acne vulgaris, which raises the issue of antibiotic resistance. Due to improper application and supervision of antibiotics, antibiotic resistance has become a serious problem in China. So, the efficacy of antimicrobial therapy in acne is unclear without an objective monitor of antibiotic resistance of Propionibacterium acnes. This cross-sectional, multicenter observational study is aimed at understanding the status of antibiotic resistance in P. acnes, investigating the measures of acne management in China and analyzing the genotypes of antibiotic-resistant strains of P. acnes. Altogether, 312 strains of P. acnes were collected from patients in five medical centers across central China after reviewing the corresponding medical history in detail. The samples underwent antibiotic susceptibility assays by agar dilution method with a total of 11 classes of antibiotics being tested. The antibiotic-resistant strains were screened and further analyzed by investigation of the genotypes regarding 23S rRNA, 16S rRNA and erm(X). The predominant resistance occurred in macrolides and lincomycin with an overall resistance rate of 47.8%. The resistance to tetracyclines was scarce with only two cases identified. The emergence of minimum inhibitory concentration elevation for tetracyclines is associated with its application history (P resistance strains were also spotted in Chinese subjects while other resistance determinants may also exist. The tetracyclines have been proved to be vastly susceptible while macrolides and lincomycin face a serious resistance status in China. © 2015 Japanese Dermatological Association.

    Full Text Available Facial reconstructions in archaeology allow empathy with people who lived in the past and enjoy considerable popularity with the public. It is a common misconception that facial reconstruction will produce an exact likeness; a resemblance is the best that can be hoped for. Research at Sheffield University is aimed at the development of a computer system for facial reconstruction that will be accurate, rapid, repeatable, accessible and flexible. This research is described and prototypical 3-D facial reconstructions are presented. Interpolation models simulating obesity, ageing and ethnic affiliation are also described. Some strengths and weaknesses in the models, and their potential for application in archaeology are discussed.

    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

    Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is an inflammatory clinical condition with aseptic bone lesions and characteristic skin manifestations. A 63-year-old woman presented with vague musculoskeletal symptoms including chronic buttock pain. The clinical work-up revealed multiple spine and osteoarticular involvement. Multilevel bone marrow edema and cortical erosions involving the spine, asymmetric sacroiliitis, and osteosclerosis of the sternoclavicular joint were consistent with a diagnosis of SAPHO syndrome. Considering SAPHO syndrome in the differential diagnosis, subsequent skin inspection revealed plantar pustulosis. Despite the unique feature of accompanying skin and skeletal lesions, skin lesions could be overlooked if not suspected.

    Background: The emergence of soft tissue paradigm in orthodontics has made various soft tissue parameters an integral part of the orthodontic problem list. The purpose of this study was to determine and compare various facial soft tissue parameters on lateral cephalograms among patients with short, average and long facial patterns. Methods: A cross-sectional study was conducted on the lateral cephalograms of 180 adult subjects divided into three equal groups, i.e., short, average and long face according to the vertical facial pattern. Incisal display at rest, nose height, upper and lower lip lengths, degree of lip procumbency and the nasolabial angle were measured for each individual. The gender differences for these soft tissue parameters were determined using Mann-Whitney U test while the comparison among different facial patterns was performed using Kruskal-Wallis test. Results: Significant differences in the incisal display at rest, total nasal height, lip procumbency, the nasolabial angle and the upper and lower lip lengths were found among the three vertical facial patterns. A significant positive correlation of nose and lip dimensions was found with the underlying skeletal pattern. Similarly, the incisal display at rest, upper and lower lip procumbency and the nasolabial angle were significantly correlated with the lower anterior facial height. Conclusion: Short facial pattern is associated with minimal incisal display, recumbent upper and lower lips and acute nasolabial angle while the long facial pattern is associated with excessive incisal display, procumbent upper and lower lips and obtuse nasolabial angle.

    Full Text Available Facial expression is one of the most powerful and direct mediums embedded in human beings to communicate with other individuals’ feelings and abilities. In recent years, many surveys have been carried on facial expression analysis. With developments in machine vision and artificial intelligence, facial expression recognition is considered a key technique of the developments in computer interaction of mankind and is applied in the natural interaction between human and computer, machine vision and psycho- medical therapy. In this paper, we have developed a new method to recognize facial expressions based on discovering differences of facial expressions, and consequently appointed a unique pattern to each single expression.by analyzing the image by means of a neighboring window on it, this recognition system is locally estimated. The features are extracted as binary local features; and according to changes in points of windows, facial points get a directional motion per each facial expression. Using pointy motion of all facial expressions and stablishing a ranking system, we delete additional motion points that decrease and increase, respectively, the ranking size and strenghth. Classification is provided according to the nearest neighbor. In the conclusion of the paper, the results obtained from the experiments on tatal data of Cohn-Kanade demonstrate that our proposed algorithm, compared to previous methods (hierarchical algorithm combined with several features and morphological methods as well as geometrical algorithms, has a better performance and higher reliability.

    Facial seborrheic dermatitis (SD), a chronic inflammatory skin condition, can impact quality of life, and relapses can be frequent. Three broad categories of agents are used to treat SD: antifungal agents, keratolytics, and corticosteroids. Topical therapies are the first line of defense in treating this condition. Our objective was to critically review the published literature on topical treatments for facial SD. We searched PubMed, Scopus, Clinicaltrials.gov, MEDLINE, Embase, and Cochrane library databases for original clinical studies evaluating topical treatments for SD. We then conducted both a critical analysis of the selected studies by grading the evidence and a qualitative comparison of results among and within studies. A total of 32 studies were eligible for inclusion, encompassing 18 topical treatments for facial SD. Pimecrolimus, the focus of seven of the 32 eligible studies, was the most commonly studied topical treatment. Promiseb ® , desonide, mometasone furoate, and pimecrolimus were found to be effective topical treatments for facial SD, as they had the lowest recurrence rate, highest clearance rate, and the lowest severity scores (e.g., erythema, scaling, and pruritus), respectively. Ciclopirox olamine, ketoconazole, lithium (gluconate and succinate), and tacrolimus are also strongly recommended (level A recommendations) topical treatments for facial SD, as they are consistently effective across high-quality trials (randomized controlled trials).

    2015-06-01

    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 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.

    Different lifestyle and dietetic factors have been linked with the onset and severity of acne. To assess the complex interconnection between dietetic variables and acne. This was a reanalysis of data from a case-control study by using a semantic connectivity map approach. 563 subjects, aged 10-24 years, involved in a case-control study of acne between March 2009 and February 2010, were considered in this study. The analysis evaluated the link between a moderate to severe acne and anthropometric variables, family history and dietetic factors. Analyses were conducted by relying on an artificial adaptive system, the Auto Semantic Connectivity Map (AutoCM). The AutoCM map showed that moderate-severe acne was closely associated with family history of acne in first degree relatives, obesity (BMI ≥ 30), and high consumption of milk, in particular skim milk, cheese/yogurt, sweets/cakes, chocolate, and a low consumption of fish, and limited intake of fruits/vegetables. Our analyses confirm the link between several dietetic items and acne. When providing care, dermatologists should also be aware of the complex interconnection between dietetic factors and acne. © 2014 European Academy of Dermatology and Venereology.

    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.

    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.

    Acne vulgaris is a very common condition affecting up of 93% of adolescents. Although rare, this disease may persist in adulthood. In adult women with acne (those older than 25 years old), this condition is particularly relevant because of the refractory to conventional therapies, which makes acne a challenge for dermatologists in this group of patients. In order to its potential risk for chronicity and the involvement of visible anatomical sites such as face and upper torso, acne has been associated with a wide spectrum of psychological and social dysfunction such as depression, anxiety, suicidal ideation, somatization, and social inhibition. In particular, adult women with acne have been shown to be adversely impacted by the effect of acne on their quality of life. For the last four decades, dermatologists have used hormonal therapies for the management of acne vulgaris in adult women, which are considered a rational choice given the severity and chronicity of this condition in this group of patients. The aim of this work is to review the hormonal drugs for management of acne. © 2015 Wiley Periodicals, Inc.

    Acne vulgaris is known to impair many aspects of quality of life. However, the correlation of this impairment with clinical severity remains equivocal despite various school, community and hospital-based studies. A hospital-based study was undertaken to measure the impairment of quality of life of patients of acne vulgaris and correlate it with the severity of lesions. This was a cross-sectional, questionnaire-based study in a cohort of 100 patients of acne vulgaris attending the outpatient department of our referral hospital. A physician measured the severity of lesions using the global acne grading system, and patients assessed quality of life by completing a questionnaire (Cardiff acne disability index). A correlation of these two was done; some additional correlations were brought out through demographic data collected from the patients. There was no correlation between the severity of acne vulgaris and an impaired quality of life. Patients who consumed alcohol and/or smoked cigarettes were found to have an impaired quality of life. While the severity of acne progressively lessened in older patients, the impact on quality of life increased. The sample size was small and there was a lack of guaranteed reliability on the self-reported quality of life. The severity of acne vulgaris does not correlate with impairment in quality of life.

    The clinical symptoms of facial and truncal acne differ. Skin surface acidity (pH), which is affected by sebum secretions, reflects the different clinical characteristics of the face and trunk. However, no studies have been conducted on truncal sebum production and skin pH. We evaluated the differences and relationship between pH values of the face and trunk. We also evaluated the relationship between pH and the quantity of sebum produced in the trunk. A total of 35 female patients clinically diagnosed with truncal acne were included. We measured pH on the face and truncal area using the Skin-pH-Meter PH 905®. We measured truncal sebum secretions using the Sebumeter SM 815®. Statistical analysis was performed to evaluate the correlations and differences between pH and sebum. Facial pH was significantly higher than chest and back pH values. The correlation between pH on the trunk and the face was significant. We used linear regression equations to estimate truncal pH using only measured pH from the chin. There was no significant relationship between truncal sebum secretion and pH. This was the first study that evaluated the differences and correlations between facial and truncal pH. We found that facial pH can predict truncal pH. In addition, we conclude that differences in pH and sebum secretion between the face and trunk are one of the reasons for differences in acne symptom at those sites.

    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.

    The bactericidal effects of benzoyl peroxide (5% lotion) and hexachlorophene (3% colloidal suspension) against Propionibacterium acnes were compared in nine healthy college students who had the microbiological and skin lipid characteristics typical of acne vulgaris, but no active lesions. Each of the two medications was applied twice daily, to opposite sides of the face, for four consecutive weeks. Hexachlorophene was effective against surface aerobes but only slightly active against P acnes. It marginally reduced free fatty acid concentrations in surface lipids and in follicular porphyrin fluorescence. Conversely, benzoyl peroxide virtually eliminated P acnes and aerobes and induced substantially decreased free fatty acid concentrations and follicular fluorescence. We conclude that benzoyl peroxide exerts its antimicrobial action in the follicles and inhibits P acnes, while the antimicrobial effectiveness of hexachlorophene is limited to the skin surface.

    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 Aryan Maleki, Noorulain Khalid Faculty of Medicine, Barts and The London School of Medicine and Dentistry, London, UKWe read with great interest the paper by Zari and Alrahmani1 investigating the relationship between stress and acne among female medical students. These findings are relevant as around 20% of young people are affected by moderate-to-severe acne, and indeed acne severity is associated with increased risks of anxiety, depression and suicidal ideation.2 The authors identified that “stress severity strongly correlated with an increase in acne severity,” and suggested that stress likely has an important role in the pathogenesis of acne.1 However, the paper could have been taken further to better establish the true extent of this relationship, and ultimately whether certain patients will benefit from clinical interventions based on their perceived stress scale. View the original paper by Zari and Alrahmani.

    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...

    Full Text Available A paralisia facial causada pelo colesteatoma é pouco freqüente. As porções do nervo mais acometidas são a timpânica e a região do 2º joelho. Nos casos de disseminação da lesão colesteatomatosa para o epitímpano anterior, o gânglio geniculado é o segmento do nervo facial mais sujeito à injúria. A etiopatogenia pode estar ligada à compressão do nervo pelo colesteatoma seguida de diminuição do seu suprimento vascular como também pela possível ação de substâncias neurotóxicas produzidas pela matriz do tumor ou pelas bactérias nele contidas. OBJETIVO: Avaliar a incidência, as características clínicas e o tratamento da paralisia facial decorrente da lesão colesteatomatosa. FORMA DE ESTUDO: Clínico retrospectivo. MATERIAL E MÉTODO: Estudo retrospectivo envolvendo dez casos de paralisia facial por colesteatoma selecionados através de levantamento de 206 descompressões do nervo facial com diferentes etiologias, realizadas na UNIFESP-EPM nos últimos dez anos. RESULTADOS: A incidência de paralisia facial por colesteatoma neste estudo foi de 4,85%,com predominância do sexo feminino (60%. A idade média dos pacientes foi de 39 anos. A duração e o grau da paralisia (inicial juntamente com a extensão da lesão foram importantes em relação à recuperação funcional do nervo facial. CONCLUSÃO: O tratamento cirúrgico precoce é fundamental para que ocorra um resultado funcional mais adequado. Nos casos de ruptura ou intensa fibrose do tecido nervoso, o enxerto de nervo (auricular magno/sural e/ou a anastomose hipoglosso-facial podem ser sugeridas.Facial paralysis caused by cholesteatoma is uncommon. The portions most frequently involved are horizontal (tympanic and second genu segments. When cholesteatomas extend over the anterior epitympanic space, the facial nerve is placed in jeopardy in the region of the geniculate ganglion. The aetiology can be related to compression of the nerve followed by impairment of its

    The purpose of this prospective study was to define the enhancement pattern of the facial nerve in idiopathic facial paralysis (Bell's palsy) on magnetic resonance (MR) imaging with routine doses of gadolinium-DTPA (0.1 mmol/kg). Using 0.5 T imager, 24 patients were examined with a mean interval time of 13.7 days between the onset of symptoms and the MR examination. Contralateral asymptomatic facial nerves constituted the control group and five of the normal facial nerves (20.8%) showed enhancement confined to the geniculate ganglion. Hence, contrast enhancement limited to the geniculate ganglion in the abnormal facial nerve (3 of 24) was referred to a equivocal. Not encountered in any of the normal facial nerves, enhancement of other segments alone or associated with geniculate ganglion enhancement was considered to be abnormal and noted in 70.8% of the symptomatic facial nerves. The most frequently enhancing segments were the geniculate ganglion and the distal intracanalicular segment. (orig.)

    Chitosan (CH) is a biopolymer that exhibits a number of interesting properties such as anti-inflammatory and antibacterial activity and is also a promising platform for the incorporation of photosensitizing agents. This study aimed to evaluate the efficacy of antimicrobial activity of chitosan hydrogel formulation alone and in combination with the methylene blue (MB) associated with antimicrobial photodynamic therapy (aPDT) against planktonic and biofilm phase of Propionibacterium acnes . Suspensions were sensitized with 12.5, 25.0, 37.5, 50.0 μg/mL of MB for 10 min and biofilms to 75, 100 and 150 μg/mL for 30 min then exposed to red light (660 nm) at 90 J/cm² and 150 J/cm² respectively. After treatments, survival fractions were calculated by counting the number of colony-forming units. The lethal effect of aPDT associated with CH hydrogel in planktonic phase was achieved with 12.5 µg/mL MB and 1.9 log 10 biofilm reduction using 75 µg/mL MB. Rheological studies showed that formulations exhibited pseudoplastic non-Newtonian behavior without thixotropy. Bioadhesion test evidenced that the formulations are highly adhesive to skin and the incorporation of MB did not influence the bioadhesive force of the formulations.

    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.

    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.

    '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.
