    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.

    Acne and facial post-inflammatory hyperpigmentation are relatively common clinical conditions among adolescents and young adults, and inflict psychosocial injuries on sufferers. To document the psychosocial and self-esteem implications of acne and facial hyperpigmentation on newly admitted undergraduates. A cross-sectional survey was conducted among 200 undergraduates. Demographics and clinical characteristics were obtained and acne was graded using the US Food and Drug Administration 5-category global system of acne classification. Participants completed the Cardiff Acne Disability Index (CADI) and the Rosenberg self-esteem scale (RSES), and data were analyzed using SPSS 20. Mean age of acne onset was 16.24 ± 3.32 years. There were 168 (84.0%) cases categorized as almost clear, 24 (12.0%) as mild acne, 4 (2.0%) as moderate acne and 4 (2.0%) as severe acne. Acne with facial hyperpigmentation, compared to acne without hyperpigmentation, was associated with significant level of anxiety in 30 participants (26.5% vs 10.3%, p =0.004) and emotional distress in 40 (35.4% vs 10.3%, p self-esteem and perception of worse disease. There was no association between gender and QoL but acne was related to a reduction of self-worth. Low self-esteem was present in 1.5%, and severe acne was associated with an occasional feeling of uselessness in the male gender. Acne with facial hyperpigmentation induces poorer QoL and self-esteem is impaired only in severe acne. Beyond the medical treatment of acne, dermatologists should routinely assess the QoL and give attention to treatment of facial post-inflammatory hyperpigmentation among people of color.

    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.

    A smartphone mobile medical application is presented, that provides analysis of the health of skin on the face using a smartphone image and cloud-based image processing techniques. The mobile application employs the use of the camera to capture a front face image of a subject, after which the captured image is spatially calibrated based on fiducial points such as position of the iris of the eye. A facial recognition algorithm is used to identify features of the human face image, to normalize the image, and to define facial regions of interest (ROI) for acne assessment. We identify acne lesions and classify them into two categories: those that are papules and those that are pustules. Automated facial acne assessment was validated by performing tests on images of 60 digital human models and 10 real human face images. The application was able to identify 92% of acne lesions within five facial ROIs. The classification accuracy for separating papules from pustules was 98%. Combined with in-app documentation of treatment, lifestyle factors, and automated facial acne assessment, the app can be used in both cosmetic and clinical dermatology. It allows users to quantitatively self-measure acne severity and treatment efficacy on an ongoing basis to help them manage their chronic facial acne.

    Solid facial edema (SFE) is a rare complication of acne vulgaris. To examine the clinical features of acne patients with solid facial edema, and to give an overview on the outcome of previous topical and systemic treatments in the cases so far published. We report two cases from Switzerland, both young men with initially papulopustular acne resistant to topical retinoids. Both cases responded to oral isotretinoin, in one case combined with oral steroids. Our cases show a strikingly similar clinical appearance to the cases described by Connelly and Winkelmann in 1985 (Connelly MG, Winkelmann RK. Solid facial edema as a complication of acne vulgaris. Arch Dermatol. 1985;121(1):87), as well as to cases of Morbihan's disease that occurs as a rare complication of rosacea. Even 30 years after, the cause of the edema remains unknown. In two of the original four cases, a potential triggering factor was identified such as facial trauma or insect bites; however, our two patients did not report such occurrencies. The rare cases of solid facial edema in both acne and rosacea might hold the key to understanding the specific inflammatory pattern that creates both persisting inflammation and disturbed fluid homeostasis which can occur as a slightly different presentation in dermatomyositis, angioedema, Heerfordt's syndrome and other conditions.

    Azelaic acid demonstrates anti-inflammatory, anti-oxidative, anti-comedogenic, and anti-microbial effects. Azelaic acid 20% cream is currently approved for the treatment of acne vulgaris, and azelaic acid 15% foam has recently been approved for rosacea. Given the favorable tolerability profile of foam preparations, it is reasonable to assume that azelaic acid 15% foam could serve as a viable treatment option for facial acne. To examine the efficacy and safety of azelaic acid 15% foam in the treatment of moderate-to-severe facial acne Methods: Twenty subjects with moderate-to-severe facial acne vulgaris were enrolled in this two-center, open-label pilot study. All study subjects were treated with azelaic acid 15% foam for 16 weeks. Efficacy analyses were based on the change in facial investigator global assessment (FIGA) and changes in total, inflammatory, non-inflammatory lesion counts between baseline and week 16. There was a significant reduction in FIGA scores from baseline to week 16 (p = .0004), with 84% of subjects experiencing at least a 1 grade improvement, and 63% of subjects achieving a final grade of Clear or Almost Clear. All subjects experienced reductions in inflammatory and total lesion counts by week 16, and 89% of subjects experienced reductions in non-inflammatory lesions. Azelaic acid 15% foam was well tolerated, with almost all instances of erythema, dryness, peeling, oiliness, pruritus, and burning being of mild or trace degree, and most adverse effects resolving by the end of the study. Azelaic acid 15% foam is effective and safe in the treatment of facial acne vulgaris. Given the convenience of foam vehicles, azelaic acid 15% foam should be considered as a viable treatment option for this condition. J Drugs Dermatol. 2018;17(6):641-645.

    Full Text Available Background: 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. Aims: (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. Methods: (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/cm2 on right and 20J/cm2 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. Results: 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. Conclusions: 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 is a chronic inflammatory disease of the sebaceous-pilosebaceous unit. Interestingly, inflammation can be detected by histopathological examination and immuohistochemical analysis even in the apparently non-inflammatory acneic lesions, such as comedones. In the last years, it has been clearly demonstrated that acne development is linked to the combination of predisposing genetic factors and environmental triggers, among which a prominent role is played by the follicular colonization by Propionibacterium acnes (P. acnes). P. acnes displays several activities able to promote the development of acne skin lesions, including the promotion of follicular hyperkeratinisation, the induction of sebogenesis, and the stimulation of an inflammatory response by the secretion of proinflammatory molecules and by the activation of innate immunity, that is followed by a P. acnes-specific adaptive immune response. In addition, P. acnes-independent inflammation mediated by androgens or by a neurogenic activation, followed by the secretion in the skin of pro-inflammatory neuropeptides, can occur in acne lesions. In conclusion, acne can be considered as a model of immune-mediated chronic inflammatory skin disease, characterized by an innate immune response that is not able to control P. acnes followed by a Th1-mediated adaptive immune response, that becomes self-maintaining independently from P. acnes itself.

    In this paper, we present a new automatic diagnosis method for facial acne vulgaris which is based on convolutional neural networks (CNNs). To overcome the shortcomings of previous methods which were the inability to classify enough types of acne vulgaris. The core of our method is to extract features of images based on CNNs and achieve classification by classifier. A binary-classifier of skin-and-non-skin is used to detect skin area and a seven-classifier is used to achieve the classification task of facial acne vulgaris and healthy skin. In the experiments, we compare the effectiveness of our CNN and the VGG16 neural network which is pre-trained on the ImageNet data set. We use a ROC curve to evaluate the performance of binary-classifier and use a normalized confusion matrix to evaluate the performance of seven-classifier. The results of our experiments show that the pre-trained VGG16 neural network is effective in extracting features from facial acne vulgaris images. And the features are very useful for the follow-up classifiers. Finally, we try applying the classifiers both based on the pre-trained VGG16 neural network to assist doctors in facial acne vulgaris diagnosis.

    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.

    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 minocycline plus PDT achieved IGA score minocycline plus PDT got significant lower DLQI at 8 weeks (4.4 vs 6.3; P minocycline alone, the combination of PDT with minocycline significantly improved clinical efficacy and QOL in moderate to severe facial acne patients.

    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.

    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. The aim of the present study is to assess the efficacy and safety of fractional CO2 laser resurfacing in atrophic facial acne scars. Sixty patients with moderate to severe atrophic facial acne scars were treated with 3-4 sessions of fractional CO2 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 resurfacing as monotherapy is effective in treating acne scars especially rolling and superficial boxcar scars with minimal adverse effects.

    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.

    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.

    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.

    Propionibacterium acnes and Staphylococcus epidermidis are pus-forming bacteria that trigger inflammation in acne. The present study was conducted to evaluate the antimicrobial activities of Jeju medicinal plants against these etiologic agents of acne vulgaris. Ethanol extracts of Jeju plants were tested for antimicrobial activities by disc diffusion and broth dilution methods. The results from the disc diffusion assays revealed that four medicinal plants, Mollugo pentaphylla, Angelica anomala, Matteuccia orientalis, and Orixa japonica inhibited the growth of both pathogens. Among these, A. anomala had strong inhibitory effects. Its MIC values were 15.6 microg/ml and 125 microg/ml against P. acnes and S. epidermidis, respectively. The cytotoxic effects of the four extracts were determined by colorimetric MTT assays using two animal cell lines: human dermal fibroblasts and HaCaT cells. Although the M. orientalis root extract had moderate cytotoxicity in HaCaT cells at 200 microg/ml, most extracts exhibited low cytotoxicity at 200 microg/ml in both cell lines. In addition, the extracts reduced the P. acnes-induced secretion of interleukin-8 and tumor necrosis factor-alpha (TNF-alpha) in THP-1 cells, an indication of their anti-inflammatory effects. Based on these results, we suggest that M. pentaphylla, A. anomala, M. orientalis, and O. japonica are attractive acne-mitigating candidates for topical application.

    Propionibacterium acnes is a commensal bacterium, which is involved in acne inflammation. An antimicrobial peptide named CEN1HC-Br, which was isolated and characterized form the green sea urchin, has been shown to possess broad-spectrum antibacterial activity. Little is known concerning the potential effects of its antibacterial and anti-inflammatory properties against P. acnes. To examine the potency of CEN1HC-Br in acne treatment, we conducted experiments to analyze the antibacterial and anti-inflammatory activities of CEN1HC-Br both in vitro and in vivo. The antimicrobial activity of CEN1HC-Br was evaluated by minimal inhibitory concentration (MIC) assays using the broth dilution method. To elucidate the in vitro anti-inflammatory effect, HaCaT cells and human monocytes were treated with different concentration of CEN1HC-Br after stimulation by P. acnes. The expression of TLR2 and the secretion of the pro-inflammatory cytokines IL-6, IL-8, IL-1β, TNF-α, IL-12, respectively, were measured by enzyme immunoassays. An evaluation of P. acnes-induced ear edema in rat ear was conducted to compare the in vivo antibacterial and anti-inflammatory effect of CEN1HC-Br, the expression of IL-8, TNF-α, MMP-2 and TLR2 was evaluated by immunohistochemistry and real time-PCR. CEN1HC-Br showed stronger antimicrobial activity against P. acnes than clindamycin. CEN1HC-Br significantly reduced the expression of interleukin IL-12p40, IL-6, IL-1β, TNF-α and TLR2 in monocytes, but they were not influenced by clindamycin. Both CEN1HC-Br and Clindamycin attenuated P. acnes-induced ear swelling in rat along with pro-inflammatory cytokines IL-8, TNF-α, MMP-2 and TLR2. Our data demonstrates that CEN1HC-Br is bactericidal against P. acnes and that it has an anti-inflammatory effect on monocytes. The anti-inflammatory effect may partially occur through TLR2 down-regulation, triggering an innate immune response and the inhibition of pro-inflammatory cytokines. Copyright © 2017 The

    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

    Full Text Available Acne vulgaris is the most common skin disease, causing significant psychosocial problems such as anxiety and depression similar to a chronic illness for those afflicted. Currently, obtainable agents for acne treatment have limited use. Thus, development of novel agents to treat this disease is a high medical need. The anaerobic bacterium Propionibacterium acnes has been implicated in the inflammatory phase of acne vulgaris by activating pro-inflammatory mediators such as the interleukin-8 (IL-8 via the NF-κB and MAPK pathways. Talaromyces wortmannii is an endophytic fungus, which is known to produce high bioactive natural compounds. We hypothesize that compound C but also the crude extract from T. wortmannii may possess both antibacterial activity especially against P. acnes and also anti-inflammatory properties by inhibiting TNF-α-induced ICAM-1 expression and P. acnes-induced IL-8 release. Treatment of keratinocytes (HaCaT with P. acnes significantly increased NF-κB and activator protein-1 (AP-1 activation, as well as IL-8 release. Compound C inhibited P. acnes-mediated activation of NF-κB and AP-1 by inhibiting IκB degradation and the phosphorylation of ERK and JNK MAP kinases, and IL-8 release in a dose-dependent manner. Based on these results, compound C has effective antimicrobial activity against P. acnes and anti-inflammatory activity, and we suggest that this substance or the crude extract are alternative treatments for antibiotic/anti-inflammatory therapy for acne vulgaris.

    Full Text Available Background: Treatment of acne scars with ablative fractional laser resurfacing has given good improvement. But, data on Indian skin are limited. A study comparing qualitative, quantitative, and subjective assessments is also lacking. Aim: Our aim was to assess the improvement of facial acne scars with Erbium-doped Yttrium Aluminium Garnet (Er:YAG 2940 nm fractional laser resurfacing and its adverse effects in 25 patients at a tertiary care teaching hospital. Methods: All 25 patients received four treatment sessions with Er:YAG fractional laser at 1-month interval. The laser parameters were kept constant for each of the four sittings in all patients. Qualitative and quantitative assessments were done using Goodman and Barron grading. Subjective assessment in percentage of improvement was also documented 1 month after each session. Photographs were taken before each treatment session and 1 month after the final session. Two unbiased dermatologists performed independent clinical assessments by comparing the photographs. The kappa statistics was used to monitor the agreement between the dermatologists and patients. Results: Most patients (96% showed atleast fair improvement. Rolling and superficial box scars showed higher significant improvement when compared with ice pick and deep box scars. Patient′s satisfaction of improvement was higher when compared to physician′s observations. No serious adverse effects were noted with exacerbation of acne lesions forming the majority. Conclusion: Ablative fractional photothermolysis is both effective and safe treatment for atrophic acne scars in Indian skin.Precise evaluation of acne scar treatment can be done by taking consistent digital photographs.

    Acne patients experience not only a medical disease but also an aesthetic condition, and this latter complication greatly motivates patients to seek out the best treatment regimen to hasten improvement in their appearance. The available clinical procedures for acne treatment include salicylic acid 30% peel and pneumatic broadband light (PBBL). The objective of this study was to compare the efficacy of salicylic acid 30% peel and PBBL treatments in patients with mild to moderately severe facial acne vulgaris. Twelve patients were recruited for a 12-week prospective, single-blind, randomized, split-face study. Patients were treated with a salicylic acid 30% peel on one side of the face and PBBL treatment was administered on the opposite side of the face for 6 consecutive weeks without other acne treatments. At every visit, treatment evaluations were performed using a modified Global Acne Grading Score (mGAGS), acne quality of life (QOL) questionnaire, Wong-Baker FACES Pain Rating Scale (WBPRS) assessments, and clinical photography. Improvement in acne symptoms was observed for both treatment procedures without significant differences and with minimal side effects. Salicylic acid 30% peel and PBBL were well tolerated in our study, and both clinical procedures were efficacious and well-tolerated by the patients.

    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

    Background: A number of treatments for reducing the appearance of acne scars are available, but general guidelines for optimizing acne scar treatment do not exist. The aim of this study was to compare the clinical effectiveness and side effects of fractional carbon dioxide (CO2) laser resurfacing combined with punch elevation with fractional CO2 laser resurfacing alone in the treatment of atrophic acne scars. Materials and Methods: Forty-two Iranian subjects (age range 18–55) with Fitzpatrick skin types III to IV and moderate to severe atrophic acne scars on both cheeks received randomized split-face treatments: One side received fractional CO2 laser treatment and the other received one session of punch elevation combined with two sessions of laser fractional CO2 laser treatment, separated by an interval of 1 month. Two dermatologists independently evaluated improvement in acne scars 4 and 16 weeks after the last treatment. Side effects were also recorded after each treatment. Results: The mean ± SD age of patients was 23.4 ± 2.6 years. Clinical improvement of facial acne scarring was assessed by two dermatologists blinded to treatment conditions. No significant difference in evaluation was observed 1 month after treatment (P = 0.56). Their evaluation found that fractional CO2 laser treatment combined with punch elevation had greater efficacy than that with fractional CO2 laser treatment alone, assessed 4 months after treatment (P = 0.02). Among all side effects, coagulated crust formation and pruritus at day 3 after fractional CO2 laser treatment was significant on both treatment sides (P < 0.05). Conclusion: Concurrent use of fractional laser skin resurfacing with punch elevation offers a safe and effective approach for the treatment of acne scarring. PMID:26538695

    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.

    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.

    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.

    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.

    There is a need for new oral antibiotics for acne with improved safety profiles and targeted antibacterial spectra. Sarecycline is a novel, tetracycline-class antibiotic specifically designed for acne, offering a narrow spectrum of activity compared with currently available tetracyclines, including less activity against enteric Gram-negative bacteria. This phase 2 study evaluated the efficacy and safety of three doses of sarecycline for moderate to severe facial acne vulgaris. In this multicenter, double-blind, placebo-controlled study, patients aged 12 to 45 years were randomized to once-daily sarecycline 0.75 mg/kg, 1.5 mg/kg, 3.0 mg/kg, or placebo. Efficacy analyses included change from baseline in inflammatory and noninflammatory lesion counts at week 12, with between-group comparisons using analysis of covariance. Safety assessments included adverse events (AEs), clinical laboratories, vital signs, electrocardiograms, and physical examinations. Overall, 285 randomized patients received at least one dose of study drug. At week 12, sarecycline 1.5 mg/kg and 3.0 mg/kg groups demonstrated significantly reduced inflammatory lesions from baseline (52.7% and 51.8%, respectively) versus placebo (38.3%; P=0.02 and P=0.03, respectively). Sarecycline was safe and well tolerated, with similar gastrointestinal AE rates in sarecycline and placebo groups. Vertigo and photosensitivity AEs occurred in less than 1% of patients when pooling sarecycline groups; no vulvovaginal candidiasis AEs occurred. Discontinuation rates due to AEs were low. No serious AEs occurred. Once-daily sarecycline 1.5 mg/kg significantly reduced inflammatory lesions versus placebo and was safe and well tolerated with low rates of AEs, including gastrointestinal AEs. Sarecycline 3.0 mg/kg did not result in additional efficacy versus 1.5 mg/kg. Sarecycline may represent a novel, once-daily treatment for patients with moderate to severe acne. It offers a narrow antibacterial spectrum relative to other

    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.

    A 19-year-old Japanese man had been treated for ulcerative colitis for 2 years. He was admitted to our hospital with nodulocystic inflammatory papules and pustules on his face and chest, high-grade fever, arthralgia and general malaise. A biopsy specimen from a pustule showed prominent infiltration of neutrophils in the epidermis and dermis, particularly around hair follicles. We made a diagnosis of acne fulminans. The systemic administration of prednisolone at 30 mg daily for 1 week immediately improved his skin lesions and other symptoms; however, during tapering of prednisolone at 20 mg daily, skin lesions flared up. The addition of oral diaminodiphenylsulfone improved the skin lesions. Although there have been a few reports of acne fulminans associated with Crohn's disease, this is the first case report of acne fulminans in a patient with ulcerative colitis. It is noteworthy that the addition of diaminodiphenylsulfone was effective for treating the relapse of acne fulminans in this case. Copyright © 2011 S. Karger AG, Basel.

    This 12-week, single-center, investigator-blinded, randomized, parallel-design study assessed the safety and efficacy of tretinoin microsphere gel 0.04% delivered by pump (TMG PUMP) to tazarotene cream 0.05% (TAZ) in mild-to-moderate facial acne vulgaris. Efficacy measurements included investigator global assessment (IGA), lesion counts, and subject self-assessment of acne signs and symptoms. Efficacy was generally comparable between treatment groups, although TMG PUMP provided more rapid results in several parameters. IGA showed a more rapid mean change from baseline at week 4 in the TMG PUMP group (-0.18 versus -0.05 in the TAZ subjects). TMG PUMP yielded more rapid improvement in papules. At week 4, the mean percentage change from baseline in open comedones was statistically significant at -64% in the TMG PUMP group (P=0.0039, within group) versus -19% in the TAZ group (not statistically significant within the group; P=0.1875). Skin dryness, peeling and pruritus were significantly less in the TMG PUMP group as early as week 4. Adverse events related to study treatment were rare in both groups and all resolved upon discontinuation of study medication.

    The first reported case of facial paralysis due to an inflammatory pseudotumor (IPT) of the facial nerve as a complication of epidermal nevus syndrome (ENS) is herein presented. A 10-month-old female patient was diagnosed with ENS at 3 months of age. She was referred to us because of moderate left facial paralysis. Epidermal nevi of her left auricle extended deep into the external ear canal. Otoscopy revealed polypous nevi and cholesteatoma debris filling the left ear. Computed tomography showed a soft mass filling the ear canal, including the middle ear, and an enormously enlarged facial nerve. Surgical exploration revealed numerous polypous nevi, external ear cholesteatoma, and tumorous swelling of the facial nerve. The middle ear ossicles were completely lost. The facial paralysis was improved after decompression surgery, but recurred 5 months later. A second operation was conducted 10 months after the first. During this operation, facial nerve decompression was completed from the geniculate ganglion to near the stylomastoid foramen. Histological diagnosis of the facial nerve tumor was IPT probably caused by chronic external ear inflammation induced by epidermal nevi. The facial paralysis gradually improved to House-Blackmann grade III 5 years after the second operation. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    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.

    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.

    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.

    Background: 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. Aims: To assess the impact of acne on the various psychosocial domains of daily life. Materials and Methods: 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. Results: 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.

    Erythema-directed digital photography is a novel method for evaluating the efficacy and tolerability of topical acne treatments. Here, we describe three case reports in which erythema-directed digital photography was used to evaluate acne before and after up to 12 weeks of treatment with clindamycin 1%/tretinoin 0.025% (Clin-RA). Erythema-directed digital photography was used to evaluate acne in three patients with mild-to-moderate facial acne, two of whom had refused to continue previous topical acne treatment (benzoyl peroxide 5% and clindamycin 1%/benzoyl peroxide 5%) due to persistent irritation. Acne lesions and erythema were evaluated using standard clinical photography and erythema-directed digital photography (VISIA-CR ™ system) before and after 8-12 weeks of treatment with Clin-RA. Erythema-directed digital photography revealed background erythema from previous topical acne treatments that was not evident from standard clinical photographs and allowed a better visualization of both inflammatory and non-inflammatory lesions. In all patients, there was a clear improvement in background erythema and a reduction in acne lesions following treatment with Clin-RA. This study has demonstrated for the first time that erythema-directed digital photography can enhance the evaluation of the efficacy and tolerability of topical acne treatments. These cases show that Clin-RA was associated with improved efficacy and tolerability vs previous treatments with topical monotherapy (benzoyl peroxide 5%) or a topical fixed-dose combination (clindamycin 1%/benzoyl peroxide 5%). © 2018 The Authors.

    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.

    Acne is a chronic inflammatory disease of the pilocebaceous unit that presents with various spectrum and severity. Genetic backgrounds and environmental factors are also considered to be relevant, but few studies have focused on Korean patients. A cross-sectional epidemiologic study on family history of Korean acne patients was performed to analyze family history of acne, and to compare the severity and characteristics of acne in association with family history. A total of 221 patients were enrolled, 98 male (44.3%) and 123 female (55.7%). Patients were grouped as patients with (A+) or without (A-) family history of acne. In a second analysis, patients with any experience of acne treatment were evaluated. Severity of acne was measured with Burton's grading system and Korean Acne Grading System (KAGS). Female patients had a higher tendency to have family history than males (P = 0.002). Group A+ had statistically significant earlier onset of acne (P = 0.002). In inexperienced patients, patients with family history showed a relatively earlier onset (P = 0.084). This study confirmed the role of heredity in acne. Family history of acne is associated with earlier onset of the disease, and more non-inflammatory lesions. © 2014 Japanese Dermatological Association.

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

    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.

    Full Text Available Background: Acne vulgaris is a common chronic inflammatory disease of pilosebaceous unit. Different factors have been suggested to influence acne including diet, menstruation and occupation. The role of some of these factors on acne intensity is confirmed. The affect of Cigarette smoking on acne intensity has been suggested. In this research, we evaluated the association between cigarette smoking and the acne intensity.Materials and Methods: This cross-sectional study was performed on 278 smoker and 277non smoker males referred to dermatology clinics of Semnan during 2006-2007. The dermatologists interviewing the patients completed questionnaires based on clinical diagnosis and intensity of acne. Data analysis was performed using t-test, Mann-Whitney, Chi-square and Spearman coefficient tests. P-value less than 0.05 were considered significant. Results: Severe acne was observed in 16.6% of non-smokers and 22.7% of smokers. Distribution of acne intensity in both groups was significant (P=0.023. Association between duration of cigarette smoking and acne intensity was significant too (P<0.001. The association between dosage of cigarette smoking and acne intensity was also significant (P<0.001.Conclusion: Significant association between cigarette smoking and acne intensity showed that smoking withdrawal is helpful for reducing the acne intensity

    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.

    In recent years, a number of studies have evaluated the treatment of acne using electromagnetic waves, such as lasers, photodynamic therapy, visible light or radio waves. While the efficacy of laser treatment is still uncertain, photodynamic therapy shows promising results, but with marked side-effects, as destruction of sebaceous glands. Treatment with blue light (405-420 nm wavelength) also appears effective and can be regarded as an treatment option for inflammatory acne.

    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.

    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.

Participants were evaluated with the "ECCA Grading Scale" before the first session, 3 months (short-term evaluation) and 3 years after the last session (long-term evaluation). Participants received two or three treatment sessions at 4-week intervals, with a 10,600 nm fractional carbon dioxide laser with pulse energies ranging between 100 and 160 mJ, 120 spot type, 75-100 spot/cm 2 density, and 30 W power. Self-assessments by the participants were done 3 months and 3 years after the last session. The mean ECCA score was 107.90 ± 39.38 before the first session, and 82.17 ± 36.23 at the time of short-term evaluation (p = 0.000). The grade of improvement at the short-term evaluation was as follows: no improvement, mild, moderate, and significant improvement for 7 (22.6%), 11 (35.5%), 9 (29%), and 4 (12.9%) of the participants, respectively. Regarding self-assessments, 80.6 and 61.3% of the participants rated themselves as having at least mild improvement at the short-term and the long-term follow-up periods, respectively. The results of this study suggest that fractional carbon dioxide laser is an efficient treatment option for acne scars. Furthermore, self-assessment results show that more than half of the participants still experience at least mild improvement at the end of 3 years.

    Full Text Available Propionibacterium acnes (P. acnes has been implicated in the pathogenesis of acne vulgaris which is the most common cutaneous disorder. It has a proinflammatory activity and takes part in immune reactions modulating the Th1/Th2 cellular response. The exposure of dendritic cells (DCs to whole bacteria, their components, cytokines or other inflammatory stimuli and infectious agents induces differentiation from immature DCs into antigen-presenting mature DCs. The aim of the study was to evaluate the capability of P. acnes to induce the maturation of DCs. We stimulated monocyte derived dendritic cells (Mo-DCs from acne patients with various concetrations of heat-killed P. acnes (10(6-10(8 bacteria/ml cultured from acne lesions. The results showed an increase in CD80+/CD86+/DR+ and CD83+/CD1a+/DR+ cells percentage depending on the concetration of P. acnes. The expression of CD83 and CD80 (shown as the mean fluorescence intensity - MFI increased with higher concetrations of P. acnes. There were also significant correlations between MFI of CD83, CD80, CD86 and concetration of P. acnes. The study showed that P. acnes in the concetration of 10(8 bacteria/ml is most effective in the induction of Mo-DCs maturation. Futher studies concerning the influence on the function of T cells are needed.

    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.

    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.

    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.

    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.

    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.

    Steroid acne is a folliculitis that can result from systemic or topical administration of steroid, and has been described as showing a similar clinical picture to Pityrosporum folliculitis, but there have been few reports about the incidence of Pityrosporum ovale and the effect of antimycotic drugs in steroid acne and other acneiform eruptions. Our purpose was to describe the association between steroid acne and P. ovale, and to confirm the superior efficacy of oral antifungal drugs over anti-acne drugs in the treatment of steroid acne. The history, clinical features direct microscopy, histopathologic analysis, and therapeutic results of 125 cases with steroid acne or other acneiform eruptions were described and compared. Over 80% of patients with acneiform eruption receiving systemic steroid revealed significant numbers of P. ovale in the lesional follicle. Furthermore, oral antifungal drug (itraconazole) showed significantly better clinical and mycologic effects than any other group of medications used in this study. Steroid acne and other acneiform eruptions showing discrete follicular papules and/or pustules localized to the upper trunk and acneiform facial skin lesions associated with multiple acneiform lesions on the body in the summer period should be suspected as Pityrosporum folliculitis. In addition, oral antifungal drugs recommended for Pityrosporum folliculitis; however, it will require a larger case-control study to confirm the superiority of antifungal therapy over anti-acne treatment.

    Full Text Available BACKGROUND: Chemical peeling is a skin-wounding procedure that may have some potentially undesirable side-effects. AIMS: The present study is directed towards safety concerns associated with superficial chemical peeling with salicylic acid in various facial dermatoses. METHODS: The study was a non-comparative and a prospective one. Two hundred and sixty-eight patients of either sex, aged between 10 to 60 years, undergoing superficial chemical peeling for various facial dermatoses (melasma, acne vulgaris, freckles, post-inflammatory scars/pigmentation, actinic keratoses, plane facial warts, etc. were included in the study. Eight weekly peeling sessions were carried out in each patient. Tolerance to the procedure and any undesirable effects noted during these sessions were recorded. RESULTS: Almost all the patients tolerated the procedure well. Mild discomfort, burning, irritation and erythema were quite common but the incidence of major side-effects was very low and these too, were easily manageable. There was no significant difference in the incidence of side-effects between facial dermatoses (melasma, acne and other pigmentary disorders. CONCLUSION: Chemical peeling with salicylic acid is a well tolerated and safe treatment modality in many superficial facial dermatoses.

    Hoffman, Lauren K; Del Rosso, James Q; Kircik, Leon H

    2017-06-01

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

    To investigate the association among acne, depressive symptoms and suicidal ideation in Finnish male military conscripts. Consecutive 165 acne patients and 150 patients with mild knee symptoms for comparison were enrolled in the study conducted in the Central Military Hospital, Helsinki, Finland. They filled out the following questionnaires: General Health Questionnaire (GHQ-12), Beck Depression Inventory (BDI), Alcohol Use Disorders Identification Test and Rosenberg Self-Esteem Scale. The Leeds acne grading scale was used to estimate the severity of acne. Sixteen (9.7%) acne patients and 20 (13.3%) comparison patients had at least moderate level of depressive symptoms (BDI score 10; P > 0.05, between groups). Suicidal ideation (BDI suicidal item score 1) was reported by 24 (14.5%) acne patients and 16 (10.7%) comparison patients (P > 0.05, between groups). When comparing the mild facial acne patients (Leeds score 0-3) with those with moderate-severe facial acne (Leeds score 4), there were no statistical differences in depressive symptoms (9.5% vs. 10.0%) or suicidal ideation (13.7% vs. 15.7%). No linear relationship was observed between the BDI and facial Leeds scores (P > 0.05). Risk factors for suicidal ideation among the acne patients were depression and alcohol risk use. Young male patients with acne do not suffer more depressive symptoms or suicidal ideation than patients with mild knee symptoms, and the severity of acne is not associated with the presence of depressive symptoms. The risk factors for suicidal ideation among acne patients seem to be similar to those found in the general population.

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.

    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.

    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 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)

    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 Abstract 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

    Full Text Available Adele Sparavigna, Beatrice Tenconi, Ileana De Ponti, Laura La PennaDermIng srl, Clinical Research and Bioengineering Institute, Monza, MB, ItalyAbstract: Acne is characterized by primary lesions on the face, chest, and back, and by a variety of other signs and symptoms. 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

    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.

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

    Directory of Open Access Journals (Sweden)

    E. Anne Eady

    2013-01-01

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

    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.

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

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

    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.

    2016-11-01

    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.

    Background : Acne vulgaris is an inflammatory skin disorder with not as yet fully understood pathogenesis. In this controlled study, we assessed acne vulgaris patients for several possible pathogenic factors such as vitamin D deficiency, vegan diet, increased body mass index (BMI) and positive anti-transglutaminase antibody. Methods : We screened 10 years of records at a family medicine clinic for patients diagnosed with acne vulgaris. In eligible subjects, we collected data regarding 25-hydroxylvitamin D levels, BMI, dietary preference and serum IgA tissue transglutaminase levels. Controls were age- (+/- 12 months) and sex-matched patients seen during the study period without a diagnosis of acne vulgaris. Results : 453 patients were given a diagnosis of acne vulgaris during the study period. Compared with controls, we found significant associations between vitamin D deficiency (4.0U/mL) and a diagnosis of acne vulgaris. Conclusions : Our study adds important information to the current body of literature in pursuit of elucidating the pathogenesis of this complex multifactorial disease.

    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.

    There are multiple global scales for acne severity grading but no singular standard. Our objective was to determine the essential clinical components (content items) and features (property-related items) for an acne global grading scale for use in research and clinical practice using an iterative method, the Delphi process. Ten acne experts were invited to participate in a Web-based Delphi survey comprising 3 iterative rounds of questions. In round 1, the experts identified the following clinical components (primary acne lesions, number of lesions, extent, regional involvement, secondary lesions, and patient experiences) and features (clinimetric properties, ease of use, categorization of severity based on photographs or text, and acceptance by all stakeholders). In round 2, consensus for inclusion in the scale was established for primary lesions, number, sites, and extent; as well as clinimetric properties and ease of use. In round 3, consensus for inclusion was further established for categorization and acceptance. Patient experiences were excluded and no consensus was achieved for secondary lesions. The Delphi panel consisted solely of the United States (U.S.)-based acne experts. Using an established method for achieving consensus, experts in acne vulgaris concluded that an ideal acne global grading scale would comprise the essential clinical components of primary acne lesions, their quantity, extent, and facial and extrafacial sites of involvement; with features of clinimetric properties, categorization, efficiency, and acceptance.

    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.

  19. 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 Context Iranian traditional medicine (ITM is based on humoral theory. Temperament or Mizaj is the result of a combination of four cardinal humors. They are blood, phlegm, yellow bile (Safra and black bile (melancholy. Like any other disease, acne is the result of humoral imbalance. Acne is a highly prevalent dermatologic problem, which has both physical and psychological effects. The aim of this study was to introduce the etiology of acne and its remedies from the perspective of ITM. Evidence Acquisition Etiology and treatment of acne were studied and analyzed from selected medical textbooks of ITM. Some of the effective plants in these books were assessed in a table, and their anti-acne activities were compared with conventional medicine’s database. Results From the perspective of ITM, considering six essential schemes for health, diet and herbal remedies as well as manipulation are recommended for acne treatment. Although the introduced plants have antibacterial, anti-inflammatory and antioxidant effects but some of them have special proven effects on acne formation process. There is also a strong relationship between digestive system and skin. Conclusions This paper was rendered to show ancient Persian scholar’s point of view about acne and its treatment, and it was shown that Iranian traditional medicine has practical recommendations for acne treatment.

    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

    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.

    The medical treatment of acne is generally sufficient to meet the expectations of acne patients. However, in a number of situations additional therapeutic approaches may be advisable. There are a wide variety of useful physical methods. They range from electromagnetic waves, usually light, to peeling and manual therapy. Phototherapy of acne includes not just visible light but also laser and flash lamp therapy. The present review provides an overview on the evidence. Visible light, in particular blue light, provides an effective option for treatment of inflammatory acne. Photodynamic therapy also is efficacious; however, it should not be used because of an unfavorable risk-benefit ratio. UV treatment of acne is obsolete. Newer studies on the use of a variety of laser systems and flash lamps have demonstrated in part rewarding results.

    Environmental pollutants can result in a variant of acne called ‘chloracne’. Chloracne is caused by systemic exposure to certain halogenated aromatic hydrocarbons ‘chloracnegens’, and is considered to be one of the most sensitive indicators of systemic poisoning by these compounds. Dioxin is the most potent environmental chloracnegen. Most cases of chloracne have resulted from occupational and non-occupational exposures, non-occupational chloracne mainly resulted from contaminated industrial wastes and contaminated food products. Non-inflammatory comedones and straw-colored cysts are the primary clinical manifestation of chloracne. Increasing of cysts in number is a signal of aggravation of chloracne. Generalized lesions can appear on the face, neck, trunk, exterimities, genitalia, axillary and other areas. Course of chloracne is chronic. Severity of chloracne is related to dosage of exposed chloracnegens, chloracnegenic potency and individual susceptibility. Histopathology of chloracne is characterized mainly by hyperplasia of epidermal cell, while follicular and sebaceous gland are taken placed by keratinized epidermal cell. The pathogenesis of chloracne maybe related to the imbalance of epidermal stem cell. Chloracne appears to be resistant to all tested forms of treatment. The only way to control chloracne is to prevent exposure to chloracnegens. PMID:20436879

    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.

    Full Text Available Acne is a common disease especially among teenagers. It has a considerable psychological impact on affected individuals. The aim of this paper was to assess if the effect of acne on acne-related quality of life is correlated to acne clinical severity. 112 university female students attending the university medical clinics with acne complaints were examined. Cardiff Acne Disability Index (CADI was used to assess acne-related quality of life, and global acne grading system (GAGS was used to assess clinical severity of acne. There was no correlation between acne severity (GAGS scoring system and quality of life impairment as assessed by CADI score (=0.145, =.127. Additionally, CADI score did not correlate with disease duration or age of patients. We therefore conclude that acne clinical severity alone does not affect acne-related quality of life changes. Many other factors might play a role.

    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.

    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.

    Chronic inflammation in the prostate, seen as infiltration of inflammatory cells into the prostate gland in histological samples, affects approximately half the male population without indication of prostate disease, and is almost ubiquitous in patients diagnosed with benign prostate hyperplasia and cancer. Several studies have demonstrated the gram-positive bacterium Propionibacterium acnes to be frequently present in prostate tissue from men suffering from prostate disease. P. acnes has been shown to be associated with histological inflammation in human prostatectomy specimens, and also to induce strong inflammatory response in prostate-derived tissue culture models. The present paper describes a rat model for assessment of the pathogenic potential of P. acnes in prostate. Prostate glands of Sprague Dawley rats (n = 98) were exposed via an abdominal incision and live P. acnes or, in control rats, saline were injected into the ventral and dorso-lateral lobes. Rats were sacrificed 5 days, 3 weeks, 3 months and 6 months post infection, and prostate tissue was analyzed for bacterial content and histological inflammation. Rat sera were assessed for levels of CRP and anti-P. acnes IgG. Live P. acnes could be recovered from the dorso-lateral lobes up to 3 months post infection, while the ventral lobes were cleared from bacteria at that time. In samples up to 3 months post infection, the dorso-lateral lobes exhibited intense focal inflammation. CRP and IgG levels were elevated throughout the span of the experiment, and reached maximum levels 3 weeks and 3 months post infection, respectively. We show that P. acnes have the potential to cause chronic infection in previously healthy prostate, and that the infection has potential to cause chronic histological inflammation in the infected tissue. The high prevalence of P. acnes in human prostate tissue calls for resolution of pathogenic details. The present rat model suggests that complications such as chronic

    Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Small, noninflamed acne lesions may not be more than a slight nuisance, but, in individuals with more severe inflammatory disease, pain, social embarrassment, and both physical and psychological scarring can be life altering. Despite its high prevalence, no previous community-based studies have been conducted in Arar, northern border of Kingdom of Saudi Arabia, addressing this issue. The aim of this study was to estimate the prevalence of acne vulgaris, to describe the sociodemographic characteristics of cases, and to determine the aggravating factors and the psychological impact of acne vulgaris in a representative sample of secondary school male students in Arar city, Kingdom of Saudi Arabia. This was a cross-sectional study. A multistage systematic random sampling technique was followed. A total of 400 male students during the academic year 2015-2016 were included in the study. Data were collected by means of personal interview and filling-in a questionnaire. The overall prevalence of acne vulgaris was 53.5%. The mean age of onset was 15.0±1.2 years. Positive family history of acne vulgaris was found in 46.7% of cases. The skin was greasy in 61.7% of cases. Acne site was the face in 67.3%, the back in 4.7%, and both in 28% of the cases. More than half (54.2%) of the cases had first-degree acne. Students mentioned several factors affecting the appearance of acne; 59.8% of cases reported a relation of increased acne appearance with the cleanliness of the skin, 35.5% reported relation with consumption of fatty meals, 24.2% with eating chocolate, 23.3% with consumption of spicy food, 12.1% with excess intake of cola drinks, 31.8% with heavy smoking, and 60.7% reported increased acne appearance in summer months. Acne was highly prevalent among secondary school male students in Arar city, Kingdom of Saudi Arabia. Several risk factors increased the appearance of acne, including

    Acne vulgaris has an important genetic predisposition, as well as keratosis pilaris. Clinical observations suggest that patients with keratosis pilaris have less frequent or less severe acne breakouts; however, we found no studies on this regard To determine if the presence of keratosis pilaris is associated with lower prevalence and severity of acne. A cross-sectional study was conducted with dermatology outpatients aged between 14 and 35 years. We evaluated history and clinical grade of acne, demographic variables, history of atopy, smoking, and use of hormonal contraceptives. Two groups were defined by the presence or absence of moderate to severe keratosis pilaris on the arms and were compared by bivariate analysis and by conditional multiple logistic regression. We included 158 patients (66% women), with a median age of 23 ± 11 years. Twenty-six percent of them had keratosis pilaris, which was associated with a history of atopy (odds ratio [OR]=2.80 [1.36 to 5.75]; pkeratosis pilaris had a less frequent history of acne (OR=0.32 [0.14 to 0.70]; pkeratosis pilaris on the arms was associated with lower prevalence of acne vulgaris and lower severity of facial lesions in adolescents and young adults.

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.

    Objective was to evaluate effectiveness of 2% tea lotion in comparisonwith 5% zinc sulphate solution in the treatment of acne vulgaris. This is asingle-blind randomly comparative therapeutic clinical trial carried out inthe Department of Dermatology, Baghdad Teaching Hospital, Iraq from June 2006to December 2007. Full history and clinical examination were studied for eachpatient regarding all relevant points of the disease, to evaluate theseverity of acne. Forty-seven patients with acne vulgaris were dividedrandomly into 2 groups and were instructed to use the following solutionstwice daily for 2 months; group A used 2% tea lotion, group B used 5% zincsulphate lotion. Patients with papulopustular lesions were included in thestudy, while patients with severe acne were excluded. The clinicalimprovement was scored by counting the number of inflammatory lesions beforeand after treatment. Forty patients completed the study, their ages rangedfrom 13-27 years with a mean+-standard deviation of 19.5+-3.5 years with 20patients in each group. Two percent tea lotion was statistically significantin decreasing the number of the inflammatory lesions in acne vulgaris, while5% zinc sulphate solution was beneficial, but did not reach statisticallysignificant level as tea lotion. Two percent of tea lotion was a goodalternative remedy to be used in the treatment of acne vulgaris and was muchsuperior than topical 5% zinc sulphate solution. (author)

    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.

    Teledermatology has undergone exponential growth in the past 2 decades. Many technological innovations are becoming available without necessarily undergoing validation studies for specific dermatologic applications. To determine whether patient-taken photographs of acne using Network Oriented Research Assistant (NORA) result in similar lesion counts and Investigator's Global Assessment (IGA) findings compared with in-person examination findings. This pilot reliability study enrolled consecutive patients with acne vulgaris from a single general dermatology practice in Los Angeles, California, who were able to use NORA on an iPhone 6 to take self-photographs. Patients were enrolled from January 1 through March 31, 2016. Each individual underwent in-person and digital evaluation of his or her acne by the same dermatologist. A period of at least 1 week separated the in-person and digital assessments of acne. All participants were trained on how to use NORA on the iPhone 6 and take photographs of their face with the rear-facing camera. Reliability of patient-taken photographs with NORA for acne evaluation compared with in-person examination findings. Acne assessment measures included lesion count (total, inflammatory, noninflammatory, and cystic) and IGA for acne severity. A total of 69 patients (37 male [54%] and 32 female [46%]; mean [SD] age, 22.7 [7.7] years) enrolled in the study. The intraclass correlation coefficients of in-person and photograph-based acne evaluations indicated strong agreement. The intraclass correlation coefficient for total lesion count was 0.81; for the IGA, 0.75. Inflammatory lesion count, noninflammatory lesion count, and cyst count had intraclass correlation coefficients of 0.72, 0.72, and 0.82, respectively. This study found agreement between acne evaluations performed in person and from self-photographs with NORA. As a reliable telehealth technology for acne, NORA can be used as a teledermatology platform for dermatology research and can

    Full Text Available Marco A Rocha, Ediléia Bagatin Paulista Medical School, Universidade Federal de São Paulo (Federal University of São Paulo, São Paulo, SP, Brazil Abstract: Acne is a multifactorial and inflammatory disease of pilosebaceous follicles, which affects most adolescents. Recent epidemiological data revealed a difference in adults affected by this disease. Women have a high prevalence and incidence when compared with men, especially after 25 years of age. In contrast to what was initially thought, most of these patients do not present endocrinopathy capable of leading to the development of the lesions. When present, polycystic ovarian syndrome is the main cause. However, in these cases, acne is rarely the only dermatological manifestation; hirsutism and acanthosis nigricans are often present. The majority of the normoandrogenic acne patients present a history since adolescence, but in many cases the lesion distribution and intensity change with time. There is often a typical localization of the lesions in the lower third of the face and lateral region of the neck. Another interesting feature is related to the impact on quality of life (QoL, which is always intense. Often there are signs of depression, even when the lesions are mild. As most adult patients are women, in addition to the conventional options, there is also hormone treatment. Combined oral contraceptives and spironolactone are good options. Knowing more about the particularities in etiopathogenesis, impact on QoL, and specific treatment options is important to all dermatologists who face the challenge of treating acne in adults.

    Full Text Available Chemical peeling is a widely used procedure in the management of acne and acne scars, but there are very few studies on Asian populations who are more prone to develop hyper pigmentation. This article aims to summarize and evaluate the existing studies on the role of chemical peels in the treatment of acne and acne scars among Asians. An online search was conducted to identify prospective studies published in English that evaluated the use of chemical peels in active acne and acne scars in Asian populations. There were six studies for acne and eight studies for acne scars that were identified using our search parameters. Most were single-centre, open label and with small sample sizes. Acne severity was not uniformly reported and the objective outcome measures of some studies were not explicitly reported as well. The general trend of the results of the studies support the safety and efficacy of chemical peels for acne and acne scars including those of darker skin types. The existing studies support the use of chemical peels in the treatment of acne and acne scars in Asians. Further clinical trials with better study design and more subjects are needed to further establish the role of chemical peels in Asian acne patients.

    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.

    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.

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

    Full Text Available 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.

    Acne is considered a cosmetic nuisance in Malaysia since no insurance coverage is provided for its treatment. Its psychological impact is unknown. The aim of this study is to determine the impact of acne on quality of life and its relationship with severity. A cross-sectional study using the Cardiff acne disability index (CADI) and Global Acne Grading System for acne severity grading was done in three government-run dermatology clinics in Sarawak, Malaysia. The study cohort of 200 patients had a mean CADI score of 5.1. Most of the patients (59.5%) had mild CADI impairment, with the domain of feelings most affected. Patients with a family income 0.05). The correlation between CADI and mild acne severity was low (Pearson correlation coefficient=0.35; pSarawak was moderate and must be addressed. It should be viewed as a psychologically disabling disease requiring optimal management and resource allocation.

    Laser Doppler flowmetry discovered microcirculatory disorders in acne patients. Affected are arterioles as well as capillaries and venules. Combination of magnetotherapy with medication improves microcirculation in acne patients. More marked positive changes occurred in the microcirculatory system due to combined treatment compared to medication therapy only. Thus, laser Doppler flowmetry is a new, noninvasive method of assessing microcirculation in acne patients and can serve an objective criterion of treatment efficacy.

In this multicenter, randomized, double-blind, vehicle-controlled pilot study, patients applied TMG 0.04% pump or vehicle once daily to the face for 12 weeks. Efficacy measures were changes in facial lesion counts, Investigator Global Evaluation of acne severity using two scales, and Investigator Global Assessment of Improvement from baseline to week 12. Of the 110 patients enrolled, 55 received TMG 0.04% pump, and 55 received vehicle. At week 12, there was significantly greater improvement in the least-squares mean change in noninflammatory lesions with TMG 0.04% than with vehicle (-19.9 vs -9.7, p = 0.04) and a significant difference in Investigator Global Assessment of improvement at week 12 between the children treated with TMG 0.04% pump and those treated with vehicle (p = 0.02), but there were no discernible differences in static acne severity scales. Change from baseline in signs and symptoms of cutaneous irritation were similar between the active and vehicle arms at week 12. This study demonstrated statistically significant differences in the reduction of noninflammatory lesions between TMG 0.04% pump and vehicle in patients aged 9-11 with acne vulgaris. Additional studies are warranted to further characterize the safety and efficacy of TMG 0.04% pump for the treatment of acne in the preadolescent population. © 2012 Wiley Periodicals, Inc.

    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.

    Facial palsy is a daily challenge for the clinicians. Determining whether facial nerve palsy is peripheral or central is a key step in the diagnosis. Central nervous lesions can give facial palsy which may be easily differentiated from peripheral palsy. The next question is the peripheral facial paralysis idiopathic or symptomatic. A good knowledge of anatomy of facial nerve is helpful. A structure approach is given to identify additional features that distinguish symptomatic facial palsy from idiopathic one. The main cause of peripheral facial palsies is idiopathic one, or Bell's palsy, which remains a diagnosis of exclusion. The most common cause of symptomatic peripheral facial palsy is Ramsay-Hunt syndrome. Early identification of symptomatic facial palsy is important because of often worst outcome and different management. The prognosis of Bell's palsy is on the whole favorable and is improved with a prompt tapering course of prednisone. In Ramsay-Hunt syndrome, an antiviral therapy is added along with prednisone. We also discussed of current treatment recommendations. We will review short and long term complications of peripheral facial palsy.

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

    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.

    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.

    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.

Androgens are the main stimulators of sebum production. Androgens originate from the gonads and adrenal glands, but can also be locally produced within the sebaceous gland from dehydroepiandrosterone sulfate. In the presence of high androgen levels, which can be either a normal pattern of adolescence or a consequence of gonadal or adrenal disease, overproduction of sebum triggers the pathogenesis of acne which, mainly in adolescent women, has deleterious psychological consequences. Estrogens exert the opposite action on sebum production, probably due to the reduction of androgen availability, a direct consequence of estrogen-related increased production of hepatic sex hormone-binding globulin (SHBG. The inhibition of the hypothalamus-pituitary axis induced by oral contraceptives is followed by reduced androgen production. Oral contraceptives containing ethinyl estradiol, which has strong estrogenic activity, amplify the hypoandrogenic effect via estrogen-related stimulation of SHBG. The hypoandrogenic effect of oral contraceptives is modulated by the progestin compound. Progestins derived from 19-nortestosterone bind androgenic receptors, whereas others exert antiandrogenic properties by antagonizing the binding of androgens to their receptors, reduce 5α-reductase, and do not bind SHBG. Through this last effect, SHBG is freely

    A novel face compact cream (FCC) containing a new patented formulation was recently developed to provide acne patients with cosmetic camouflage for their lesions and to have beneficial effects on the multifactorial components of the disease. This pilot investigation aimed to evaluate the real-life tolerability, potential for comedogenicity and covering effect provided by this FCC. 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. 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. 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.

    Hidradenitis suppurativa/acne inversa is a chronic, inflammatory, scarring disease in the terminal hair follicle and apocrine gland-bearing areas (skin folds). There is considerable histological evidence that perifolliculitis and follicular hyperkeratosis precede the rupture of the follicle. The timing of the epithelial hyperplasia at the infundibula of inflamed terminal follicles has not yet been clarified. To clarify the early histopathological life of lesions ('chronology') in hidradenitis suppurativa/acne inversa, focusing on the terminal follicle structure and its surrounding tissue (hyperkeratosis, hyperplasia of follicular epithelium, perifolliculitis and rupture). In total, 485 operative specimens obtained from 128 patients with diagnosed hidradenitis suppurativa/acne inversa (all surgically treated by wide excision) were examined histologically. Two to five histological preparations (total 485) per operation area (total 196) were prepared by multiple slicing. Hidradenitis suppurativa/acne inversa showed a heterogeneous histological pattern: hyperkeratosis of the terminal follicles (89%), hyperplasia of follicular epithelium (80%), pronounced perifolliculitis (68%) and follicle rupture (24%). Perifolliculitis, follicular hyperkeratosis and hyperplasia occurred prior to the rupture of the follicle. Other histological criteria were: subepidermal cellular inflammatory infiltrate (82%), epidermal psoriasiform hyperplasia (56%), pronounced acute dermal inflammation (28%), pronounced chronic dermal inflammation (49%), and involvement of apocrine glands (52%) and subcutis (31%). Infundibular hyperkeratosis, hyperplasia of the follicular epithelium and perifolliculitis are major histopathological characteristics of hidradenitis suppurativa/acne inversa. These apparently precede rupture of the follicle. In particular, hyperplasia of the follicular epithelium probably marks the beginning of sinus formation, which usually spreads horizontally.

    To report a case of Propionibacterium acnes endophthalmitis in a patient with an Ahmed glaucoma valve. A nine-year-old boy with bilateral congenital glaucoma, with an Ahmed glaucoma valve implanted in the left eye, had recurrent conjunctival dehiscence and endophthalmitis. Vitreous cultures demonstrated the presence of Propionibacterium acnes. This is the first reported case of Propionibacterium acnes endophthalmitis in an Ahmed glaucoma valve and the second one in a glaucoma drainage device. We strongly recommend using a patch graft to prevent and treat tube exposure. Conjunctival grafts may be useful to close the conjunctiva when there is marked scarring to prevent patch exposure and melting or extrusion.

    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.

    Dermatologic problems of the face affect both function and aesthetics, which are based on complex anatomical features. Treating dermatologic problems while preserving the aesthetics and functions of the face requires knowledge of normal anatomy. When performing successfully invasive procedures of the face, it is essential to understand its underlying topographic anatomy. This chapter presents the anatomy of the facial musculature and neurovascular structures in a systematic way with some clinically important aspects. We describe the attachments of the mimetic and masticatory muscles and emphasize their functions and nerve supply. We highlight clinically relevant facial topographic anatomy by explaining the course and location of the sensory and motor nerves of the face and facial vasculature with their relations. Additionally, this chapter reviews the recent nomenclature of the branching pattern of the facial artery. © 2013 Elsevier Inc. All rights reserved.

    Facial nerve palsy is a condition with several implications, particularly when occurring in childhood. It represents a serious clinical problem as it causes significant concerns in doctors because of its etiology, its treatment options and its outcome, as well as in little patients and their parents, because of functional and aesthetic outcomes. There are several described causes of facial nerve paralysis in children, as it can be congenital (due to delivery traumas and genetic or malformative diseases) or acquired (due to infective, inflammatory, neoplastic, traumatic or iatrogenic causes). Nonetheless, in approximately 40%-75% of the cases, the cause of unilateral facial paralysis still remains idiopathic. A careful diagnostic workout and differential diagnosis are particularly recommended in case of pediatric facial nerve palsy, in order to establish the most appropriate treatment, as the therapeutic approach differs in relation to the etiology.

    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.

    Acne vulgaris is an inflammatory disease involving the pilosebaceous unit. Rosacea is a chronic inflammatory skin disease that affects the face in particular. This study aimed to determine if skin sebum, pH, and moisture affect the number of Demodex spp. in acne vulgaris and rosacea patients. This study focused on 30 patients each with acne vulgaris and rosacea. As a control group, 60 healthy individuals were included. In acne vulgaris patients, when compared to those with Demodex mite more than 5 /cm2 in each area, less than 5/cm2 were found to be oily, acidic, dry or very dry. However, there was no significant difference in moisture value. In patients with rosacea, the skin was acidic and dry in patients those with more than 5/cm2 Demodex mites when compared to those with demodex mite less than 5 /cm2 in patients in each of the right cheek and nose areas. There was no difference in skin oil level. The oily, acidic, dry, and very dry skin of the acne vulgaris patients and the oily, acidic, and very dry skin of the rosacea patients are factors facilitating the development of Demodex ssp.

    Ablative fractional resurfacing (AFR) is a new modality for photorejuvenation and acne scars which combines carbon dioxide (CO₂) laser ablation with fractional photothermolysis. The objective is to evaluate the efficacy and side effects of a new fractional CO₂ ablative device (Fraxel Re:pair) for skin rejuvenation and acne scars in Asians. Nine patients underwent one full-face treatment. The energy levels ranged from 30-70 mJ with coverage between 30% and 45%. Improvement in skin texture, laxity, wrinkles, enlarged pores, overall pigmentation irregularity, and adverse effects were assessed up to 6 months post-treatment. Standardized photographs using the Canfield Visia CR system® were assessed by two independent observers. Subjective improvement was assessed by patient questionnaires. Nine Chinese patients (skin types III and IV, mean age 44.8) were included. Statistically significant improvements were seen for skin texture, skin laxity, wrinkles, enlarged pores, and acne scars. The post-inflammatory hyperpigmentation rate was 55.5% and 11.1% at 1 and 6 months post-treatment, respectively. Eighty-six percent of patients were overall satisfied to very satisfied with the treatment. Ablative fractional CO₂ laser resurfacing was overall safe and effective for skin rejuvenation and acne scars in Asians. However, in view of the high post-inflammatory rate and the statistically significant but only mild to moderate improvement after a single treatment as observed in this study, there is a need to review the current role of fractional ablative CO₂ laser treatment as compared to fractional non-ablative for skin rejuvenation and acne scar treatment in Asians. © 2010 Wiley-Liss, Inc.

    Facial trauma. Patients with facial trauma must be assessed in a systematic way so as to avoid missing any injury. Severe and disfiguring facial injuries can be distracting. However, clinicians must first focus on the basics of trauma care, following the Advanced Trauma Life Support (ATLS) system of care. Maxillofacial trauma occurs in a significant number of severely injured patients. Life- and sight-threatening injuries must be excluded during the primary and secondary surveys. Special attention must be paid to sight-threatening injuries in stabilized patients through early referral to an appropriate specialist or the early initiation of emergency care treatment. The gold standard for the radiographic evaluation of facial injuries is computed tomography (CT) imaging. Nasal fractures are the most frequent isolated facial fractures. Isolated nasal fractures are principally diagnosed through history and clinical examination. Closed reduction is the most frequently performed treatment for isolated nasal fractures, with a fractured nasal septum as a predictor of failure. Ear, nose and throat surgeons, maxillofacial surgeons and ophthalmologists must all develop an adequate treatment plan for patients with complex maxillofacial trauma.

  8. Facial reconstruction for radiation-induced skin cancer

    1990-01-01

    Radiation-induced skin cancers can be difficult to diagnose and treat. Typically, a patient who has received orthovoltage radiotherapy for disorders such as acne, eczema, tinea capitis, skin tuberculosis, and skin cancer can expect that aggressive skin cancers and chronic radiodermatitis may develop subsequently. Cryptic facial cancers can lead to metastases and death. Prophylactic widefield excision of previously irradiated facial skin that has been subject to multiple recurrent skin cancers is suggested as a method of deterring future cutaneous malignancy and metastases. The use of tissue expanders and full-thickness skin grafts offers an expedient and successful method of subsequent reconstruction

  9. 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.

    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.

    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.

    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.

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

    Full Text Available There is paucity of reports in the demographic knowledge, belief and socio-psychological impact of acne vulgaris sufferers towards the disorder in a black population. 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

    2004-06-01

    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.

    Full Text Available Chemical peeling implies the application of a chemical agent to the skin, which causes controlled destruction of a part or the entire epidermis, with or without the dermis, leading to exfoliation and removal of superficial lesions, followed by regeneration of new epidermal and dermal tissues. The present study was directed toward safety concerns associated with superficial chemical peeling with glycolic acid (GA in different concentrations at patients with acne tip I. A sample of 90 patients of either sex, aged between 17 to 21 years, were included in the study and submitted to superficial chemical peeling for acne vulgaris. The study lasted eight weeks and peeling sessions were carried out in each patient. Tolerance to the procedure and any undesirable effects noted during these sessions were recorded. For data statistical analysis and interpretation of results, software program “SPSS version 13” was used. Results were expressed through the descriptive statistics, as simple frequencies and percentages, while for establishing of statistically significant differences, in use was Friedman’s test of significance. Almost all the patients tolerated the procedure well. Of totally 90 patients, only six, at the end of therapy experienced hard erythema, only ten, at the end of therapy experienced hard desquamation and only eleven, at the end of therapy experienced hard sensation of pulling of facial skin. Chemical peeling with glycolic acid is a well tolerated and safe treatment modality in acne type I.

    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.

    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.

    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.

    2008-01-01

    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...

    Szmurło, Agnieszka; Sińska, Beata

    2016-01-01

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

    Acne is not solely a cosmetic problem. The clinical importance of acne in the estimation of androgen excess disorders is controversial. Recently, the Amsterdam ESHRE/ASRM-sponsored third PCOS Consensus Workshop Group suggested that acne is not commonly associated with hyperandrogenemia and therefore should not be regarded as evidence of hyperandrogenemia. Our aim was to investigate whether acne is a sign of androgen excess disorder or not. This is a cross sectional study that was performed in a university hospital involving 207 women, aged between 18 and 45 years, suffering mainly from acne. The women were assigned as polycystic ovary syndrome (PCOS), idiopathic hirsutism (IH), idiopathic hyperandrogenemia (IHA). Women with acne associated with any of the androgen excess disorders mentioned above were named as hyperandrogenemia associated acne (HAA). Women with acne but without hirsutism and hyperandrogenemia and having ovulatory cycles were named as "isolated acne". Serum luteinizing hormone, follicle stimulating hormone, estradiol, progesterone, 17-hydroxyprogesterone, dehydroepiandrosterone-sulfate (DHEAS), androstenedione, total testosterone and lipid levels were measured. Acne score was similar between the women with isolated acne and HAA. The most common cause for acne was PCOS and only 28% of the women had isolated acne. 114 (55%) women had at least one raised serum androgen level. In this study, 72% of acneic women had clinical and/or biochemical hyperandrogenemia. In contrast to the suggestion of ESHRE/ASRM-sponsored third PCOS Consensus Workshop Group, our data indicate that the presence of androgen excess disorders should be evaluated in women presenting with acne.

    25 male patients suffering from acne vulgaris were examined by means of endocrinological, morphological, and 5 psychometric procedures in order to check the correlations and interactions between the psychological and dermatological aspects of the disease. In comparison with a control group, the acne patients did not show any striking endocrinological abnormalities; we found no correlation between the extensiveness of the lesions and the level of DHEA sulphate. All the psychological tests yielded results deviating from those achieved by the representative controls, but they were comparable with those of other patients suffering from psychosomatic diseases. The individual feeling of being "disfigured" found its expression in self-consciousness, lack of trust in his/her own body, as well as the clinically relevant difference between his/her conception of self and the ideal of self. During times of enhanced psychosocial strains subjectively assumed by the patients, the lesions increased and the patients were disturbed in social interaction and communication. Surprisingly, we did not find any correlation between the clinical status and significant psychometric findings. Our results show that in acne vulgaris, the individual experience of wanting physical attractiveness, associated with a predominantly neurotic depressive personal structure, may play a central part in a disturbed process of interaction with the environment and suggest the influence of psychic factors in the pathogenesis of acne vulgaris.

    Facial nerve palsy results in the loss of facial expression and is most commonly caused by a benign, self-limiting inflammatory condition known as Bell palsy. However, there are other conditions that may cause facial paralysis, such as neoplastic conditions of the facial nerve, traumatic nerve injury, and temporal bone lesions. We present a case of facial nerve palsy concurrent with a benign cystic lesion of the temporal bone, adjacent to the tympanic segment of the facial nerve. The patient's symptoms subsided after facial nerve decompression via a transmastoid approach.

    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.

  16. Evaluation of the efficacy and tolerability of mandelic acid-containing cosmetic formulations for acne skin care

    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.

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

    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

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

    Acne is a common skin disease characterized by elevated sebum production and inflammation of the sebaceous glands. We have previously shown that a non-psychotropic phytocannabinoid ((-)-cannabidiol [CBD]) exerted complex anti-acne effects by normalizing 'pro-acne agents'-induced excessive sebaceous lipid production, reducing proliferation and alleviating inflammation in human SZ95 sebocytes. Therefore, in this study we aimed to explore the putative anti-acne effects of further non-psychotropic phytocannabinoids ((-)-cannabichromene [CBC], (-)-cannabidivarin [CBDV], (-)-cannabigerol [CBG], (-)-cannabigerovarin [CBGV] and (-)-Δ(9) -tetrahydrocannabivarin [THCV]). Viability and proliferation of human SZ95 sebocytes were investigated by MTT and CyQUANT assays; cell death and lipid synthesis were monitored by DilC1 (5)-SYTOX Green labelling and Nile Red staining, respectively. Inflammatory responses were investigated by monitoring expressions of selected cytokines upon lipopolysaccharide treatment (RT-qPCR, ELISA). Up to 10 μm, the phytocannabinoids only negligibly altered the viability of the sebocytes, whereas high doses (≥50 μm) induced apoptosis. Interestingly, basal sebaceous lipid synthesis was differentially modulated by the substances: CBC and THCV suppressed it, and CBDV had only minor effects, whereas CBG and CBGV increased it. Importantly, CBC, CBDV and THCV significantly reduced arachidonic acid (AA)-induced 'acne-like' lipogenesis. Moreover, THCV suppressed proliferation, and all phytocannabinoids exerted remarkable anti-inflammatory actions. Our data suggest that CBG and CBGV may have potential in the treatment of dry-skin syndrome, whereas CBC, CBDV and especially THCV show promise to become highly efficient, novel anti-acne agents. Moreover, based on their remarkable anti-inflammatory actions, phytocannabinoids could be efficient, yet safe novel tools in the management of cutaneous inflammations. © 2016 John Wiley & Sons A/S.

    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.

    Surgical excision is thought to be the standard treatment of choice for lymphatic malformations. However, when the lesions are limited to the face only, surgical scar and facial nerve injury may impair cosmetics and facial expression. Sclerotherapy, an injection of a sclerosing agent directly through the skin into a lesion, is an alternative method. By evaluating facial nerve conduction, we observed the long-term effect of facial lymphatic malformations after intralesional injection of OK-432 and correlated the findings with anatomic outcomes. One 12-year-old boy with a lesion over the right-side preauricular area adjacent to the main trunk of facial nerve and the other 5-year-old boy with a lesion in the left-sided cheek involving the buccinator muscle were enrolled. The follow-up data of more than one year, including clinical appearance, computed tomography (CT) scan and facial nerve evaluation were collected. The facial nerve conduction study was normal in both cases. Blink reflex in both children revealed normal results as well. Complete resolution was noted on outward appearance and CT scan. The neurophysiologic data were compatible with good anatomic and functional outcomes. Our report suggests that the inflammatory reaction of OK-432 did not interfere with adjacent facial nerve conduction.

    Full Text Available Background and Design: Acne vulgaris is a multifactorial chronic inflammatory disase of the pilosebaceous unit. Topical antibiotics and anti-inflammatory treatment are used for mild and moderate acne. Clindamycin is frequently used for acne treatment, altough nadifloxacin is a relatively new agent. There are few studies evaluating nadifloxacin efficacy. It's impact on quality of life has not been determined previously. In this study, it is aimed to compare the effect of these two agents, and to evaluate the effect of these treatments on quality of life. Materials and Methods: Eighty patients with mild-moderate acne vulgaris were divided in two groups of 40 people that had no difference in terms of age, gender and acne severity. The combination of topical clindamycin and 5% benzoyl peroxide gel twice a day was given to group 1 for 12 weeks. The combination of nadifloxacin cream and 5% benzoyl peroxide gel twice a day was given to group 2 for 12 weeks. The number of the inflammatory and non-inflammatory lesions were recorded at baseline and on weeks 2, 4, 8, 12 and side effects were recorded and evaluated. Global improvement was evaluated separately by patients and doctor after the treatment. Before and after the treatment, the quality of life of the patients were evaluated with Skindex-29. Results: Both treatment group regimens were significantly effective on inflammatory and non-inflammatory lesions and were well tolerated by patients in terms of side effects. It was also observed that there was statistically significant recovery after treatment in terms of clinical severity and quality of life. There was not any statistically significant difference between two treatment methods in terms of effectiveness, side effect and quality of life. Conclusion: Nadifloxacin and 5% benzoyl peroxide combination is effective in the treatment and improvement of quality of life in acne patients.

    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.

    As the relationship between tobacco smoking and acne remains unclear, we examined the relationship between cigarette smoking and severe acne in a large cohort of young men. Trained nurses interviewed subjects upon discharge from compulsory military service, regarding family history, habits, and tobacco smoking habits. Data was correlated with severe acne status, as diagnosed and coded by board-certified dermatologists. In total, 27,083 male subjects participated in the study from 1983 to 2003, of which 237 (0.88%) had severe acne, 11,718 (43.27%) were active smokers, and 15,365 (56.73%) were nonsmokers at the time of interviews. Active smokers showed a significantly lower prevalence of severe acne (0.71%) than nonsmokers (1.01%) (P = 0.0078). An inverse dose-dependent relationship between severe acne prevalence and daily cigarette consumption became significant from 21 cigarettes a day (chi2 and trend test: P < 0.0001), odds ratio: 0.2 (95% CI: 0.06-0.63). The study did not aim to establish a temporal correlation, and passive smoking and acne treatments were not measured. Previous in vitro and clinical studies strongly support an association with nicotine. We suggest a trial with topical nicotine treatment for acne to further investigate this association.

    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. 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. Database summary study. Global Burden of Disease Study 2010 database. Global Burden of Disease regions comprised countries with prevalence of acne vulgaris between the ages of 15 and 19 years. 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. 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.

    There is a paucity of studies investigating laser resurfacing in Fitzpatrick skin phototypes (SPT) IV to VI. To assess the efficacy and safety of fractional nonablative laser resurfacing in the treatment of acne scarring in patients with SPT IV to VI. The authors conducted a randomized, investigator-blinded and rater-blinded, split-face comparative study of adults with SPT IV to VI and facial acne scars treated with 2 different density settings and the same fluence. Quantitative global scarring grading system (QGSGS) scores were significantly improved from baseline at 16 and 24 weeks (p = .0277). Improvements in QGSGS scores after higher and lower density treatments were statistically similar (p = .96). The live-blinded dermatologist, the blinded dermatologist photoraters, and the patients rated scars as being significantly more improved by visual analog scale at weeks 16 and 24 compared with baseline (p skin types IV to VI. Self-limited postinflammatory hyperpigmentation was a common occurrence, especially with higher treatment densities.

    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.

    To evaluate the effects of conditioned medium of adipose-derived stem cells (ADSC-CM) on efficacy and side effects after fractional carbon dioxide laser resurfacing (FxCR) when treating subjects with facial atrophic acne scars or with skin rejuvenation needs. Twenty-two subjects were enrolled in the study and divided into two groups. Nine subjects were included in skin rejuvenation group and thirteen subjects were included in acne scar group, and all subjects underwent three sessions of FxCR. ADSC-CM was applied on FxCR site of one randomly selected face side. Evaluations were done at baseline, 1 week after first treatment, and 1 month after each treatment. The outcome assessments included subjective satisfaction scale; blinded clinical assessment; and the biophysical parameters of roughness, elasticity, skin hydration, transepidermal water loss (TEWL), and the erythema and melanin index. Biopsies taken from one subject in skin rejuvenation group were analyzed using hematoxylin and eosin, Masson's Trichrome, and Gomori's aldehyde fuchsin staining. ADSC-CM combined with FxCR increased subject satisfaction, elasticity, skin hydration, and skin elasticity and decreased TEWL, roughness, and the melanin index in both acne scars and skin rejuvenation groups. Histologic analysis showed that ADSC-CM increased dermal collagen density, elastin density, and arranged them in order. ADSC-CM with FxCR is a good combination therapy for treating atrophic acne scars and skin rejuvenation. JSPH2012-082 - Registered 14 Feb 2012.

  2. Increased prevalence of metabolic syndrome in patients with acne inversa.

    Directory of Open Access Journals (Sweden)

    Robert Sabat

    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

    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.

    Androgen levels during critical periods of testicular development may be involved in the etiology of testicular germ cell tumors (TGCT). We evaluated the roles of adolescent and early adult life correlates of androgen exposure and TGCT in a hospital-based case control study. TGCT cases (n=187) and controls (n=148), matched on age, race and state of residence, participated in the study. Unconditional logistic regression was used to estimate associations between TGCT and male pattern baldness, severe acne, markers of puberty onset and body size. Cases were significantly less likely to report hair loss than controls (OR, 0.6; 95% CI, 0.4, 1.0). Amount of hair loss, increasing age at onset and increasing rate of loss were all inversely associated with TGCT (rate of hair loss: p-trend=0.03; age at onset: p-trend=0.03; amount of hair loss: p-trend=0.01). History of severe acne was inversely associated with TGCT (OR, 0.5; 95% CI, 0.3, 0.9) and height was positively associated with TGCT (p-trend=0.02). Increased endogenous androgen levels during puberty and early adulthood may be associated with decreased risk of TGCT. Additional studies of endogenous hormone levels during puberty and early adult life are warranted, especially studies evaluating the role of androgen synthesis, metabolism and uptake. PMID:21128977

    This study aims to investigate the frequency of fibromyalgia syndrome and to specify fibromyalgia syndrome-associated clinical symptoms in patients with acne vulgaris. Eighty-eight patients (28 males, 60 females; mean age 23.2±5.1 years; range 18 to 40 years) with acne vulgaris and age, sex- and body mass index-similar 76 healthy controls (14 males, 62 females; mean age 24.5±2.9 years; range 18 to 35 years) were included. Acne vulgaris was evaluated by using the Global Acne Scale, while Hospital Anxiety and Depression Scale was used to evaluate anxiety. Fibromyalgia-associated pain, sleep disturbance, anxiety, and menstrual cycle disturbance were significantly more frequent in patients with acne vulgaris than controls. Also, the severity of anxiety and the number of tender points were significantly higher in the acne vulgaris patients than controls. This study indicates that patients with acne vulgaris have increased frequency of fibromyalgia syndrome than healthy controls (21.6% versus 5.3%, respectively).

    Full Text Available In this case report we share a case of infective Pericarditis caused by Propionibacterium acnes (P. acnes in an immune-competent, nonsurgical patient. This case and review will illustrate the importance of considering P. acnes as a cause of idiopathic pericardial effusion and effusive constrictive disease. The patient was a 61-year-old male with history of osteoarthritis of the knee. He received an intra-articular steroid injection in July 2013. Two months later, he presented with atrial fibrillation and heart failure. He was found to have pericardial and bilateral pleural effusions which grew P. acnes. This organism was initially considered to be contaminant; however, as P. acnes was isolated from both pleural and pericardial fluids, he was started on oral amoxicillin. He was noted to have recurrence of effusions within 2 weeks with evidence of constrictive physiology by echocardiography. Treatment was subsequently changed to intravenous Penicillin G with marked symptomatic improvement, resolution of pericardial/pleural effusions, and no echocardiographic evidence of constrictive pericarditis at 10 weeks follow-up. Pursuit and treatment of P. acnes could lead to prevention of constrictive pericarditis. We believe that further studies are needed to assess prevalence of P. acnes and response to intravenous Penicillin G in patients presenting with effusive constrictive disease.

  8. Use of organic acids in acne and skin discolorations therapy

    Full Text Available Acne is one of the most frequent skin disorders that occurs in puberty, but often adults also have acne. The most important factors responsible for acne are elevated production of sebum by hyperactive sebaceous glands and blockage of the follicle because of hyperkeratosis [14]. The third etiopathogenic factor of acne is excessive microflora reproduction [8]. The most significant bacterium that is responsible for formation of skin lesions is Propionibacterium acnes, a rod-shaped Gram-positive and aerotolerant anaerobic bacterium. It is estimated that P. acnes is responsible for acne in approximately 80% of people aged 11 to 30 [27,40]. Even healed skin lesions can often cause skin discolorations and scar formation [51]. Exfoliating chemical substances that are commonly used in dermatology and cosmetology are organic acids. Exfoliating treatment using organic acids is called “chemical peeling” and consists of controlled application of those substances on the skin [38]. The depth of exfoliation depends on organic acid concentration, type of substance and contact time with the skin [41]. Using exfoliating agents seems to be helpful in excessive keratinization – one of several factors responsible for acne. Moreover, epidermis exfoliation is a popular method of removing skin discoloration [22]. Considering chemical structure, exfoliating substances that are most often used in cosmetology contain alpha-hydroxyacids (glycolic acid, lactic acid, mandelic acid and citric acid, beta-hydroxyacids (salicylic acid and other organic acids, such as trichloroacetic acid and pyruvic acid [47]. In this article, a literature review of use of organic acids in acne and skin discoloration therapy is presented.

    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.

    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.

    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

    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.

    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 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.

    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.

    This study aims at describing the clinical characteristics of patients with acne using skin bleaching (SB) products. This is a prospective study conducted over 8 months in three dermatology departments and one private clinic. All patients examined for acne were included in the study. The study included 119 patients examined for acne from March to October 2010. Among them 48 (40.7%) did SB. Hydroquinone was the first product used for SB (26 of 48), followed by topical corticosteroids (17 of 48). The elementary lesions were papules (99.2%), comedos (36.1%), pustules (63.9%), pigmentation (26.1%), scars (21%), and nodules (20.2%). The extent of acne on the face was observed in all patients (100%). The lesions were extensive among 43.7% of the patients. The extent of acne lesions was not statistically associated with SB. Other body areas concerned were the chest (20.2%), back, and shoulders (41.2%). The relative risk of having lesions on the back and/or shoulders when the patient practiced SB was 2.71 (CI: 1.08-6.84), which is significant. The study suggests that the back and shoulders can be the main areas for acne lesions associated with the practice of SB. The influence of different types of product is unclear. © 2012 The International Society of Dermatology.

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

    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.

    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.

    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.

    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.

    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.

    The high prevalence of acne vulgaris in teenagers has increased comorbidities. Lasers offer alternative options for acne treatment because they have rapid action, low systemic adverse effects, and do not require everyday treatment. To study the efficacy and patients' satisfaction of 595-nm pulse dye laser (PDL) treatment of acne vulgaris and acne erythema in adolescents and early adulthood, we designed a blocked-randomized, split-faced 595-nm PDL (fluence 8 J/cm 3 pulse duration 10 ms, spot size 7 mm, 2 session every 2 weeks) study in patients with mild to moderate acne by comparing the laser-treated and non-treated side. The acne lesion counts, acne erythema grading, and acne severity grading were evaluated at baseline and 2, 4, and 8 weeks. Thirty patients were recruited. The results showed no statistically significant difference except the papule count at week 4 which was -1.828 on the treated side and 0.103 on the non-treated side of the face, P-value 0.0018. There was no statistically significant difference of acne severity grading and acne erythema grading between both sides of the face. The mean scores of patients' satisfaction on the laser-treated side were 75, 81, and 81%, respectively. The PDL treatment in this study reveals no significant improvement in acne therapy; however, the patients were satisfied with this laser treatment. © 2017 The International Society of Dermatology.

    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.

    Crohn's disease is a chronic relapsing and remitting inflammatory condition which affects any part of the gastrointestinal tract. In the oro-facial region, patients can present peri-oral swellings which results in severe facial disfigurement. To date, assessing the degree of facial changes and evaluation of treatment outcomes relies on clinical observation and semi-quantitative methods. In this paper, we describe the development of a robust and reproducible measurement strategy using 3-D facial biometrics to objectively quantify the extent and progression of oro-facial Crohn's disease. Using facial laser scanning, 32 serial images from 13 Crohn's patients attending the Oral Medicine clinic were acquired during relapse, remission, and post-treatment phases. Utilising theories of coordinate metrology, the facial images were subjected to registration, regions of interest identification, and reproducible repositioning prior to obtaining volume measurements. To quantify the changes in tissue volume, scan images from consecutive appointments were compared to the baseline (first scan image). Reproducibility test was performed to ascertain the degree of uncertainty in volume measurements. 3-D facial biometric imaging is a reliable method to identify and quantify peri-oral swelling in Crohn's patients. Comparison of facial scan images at different phases of the disease revealed precisely profile and volume changes. The volume measurements were highly reproducible as adjudged from the 1% standard deviation. 3-D facial biometrics measurements in Crohn's patients with oro-facial involvement offers a quick, robust, economical and objective approach for guided therapeutic intervention and routine assessment of treatment efficacy on the clinic.

    Acne is a significant adolescent problem and may precipitate emotional and psychological effects. The impact of acne on psychological parameters and implications for acne treatment are not fully understood. We performed a MEDLINE search using the terms "acne" and "adolescent" along with "psychological," "depression," or "psychiatric," which yielded 16 reviewed studies. Qualitative review of the selected articles revealed that the presence of acne has a significant impact on self-esteem and quality of life. Depression and other psychological disorders are more prevalent in acne patients and acne treatment may improve symptoms of these disorders. The reviewed studies were semi-quantitative analyses utilizing various standardized surveys or questionnaires. Therefore, quantitative analysis of selected studies was not possible. The presence of co-morbid psychological disorders should be considered in the treatment of acne patients and future prospective trials are needed to assess the impact of treatment on psychological outcomes.

    Facial paralysis often has a significant emotional impact on patients. Along with the myriad of new surgical techniques in managing facial paralysis comes the challenge of selecting the most effective procedure for the patient. This review delineates common surgical techniques and reviews state-of-the-art techniques. The options for dynamic reanimation of the paralyzed face must be examined in the context of several patient factors, including age, overall health, and patient desires. The best functional results are obtained with direct facial nerve anastomosis and interpositional nerve grafts. In long-standing facial paralysis, temporalis muscle transfer gives a dependable and quick result. Microvascular free tissue transfer is a reliable technique with reanimation potential whose results continue to improve as microsurgical expertise increases. Postoperative results can be improved with ancillary soft tissue procedures, as well as botulinum toxin. The paper provides an overview of recent advances in facial reanimation, including preoperative assessment, surgical reconstruction options, and postoperative management.

    Evaluation of diagnostic, surgical technique, treatment results facial nerve neurinomas and its comparison with literature was the main purpose of this study. Seven cases of patients (2005-2011) with facial nerve schwannomas were included to retrospective analysis in the Department of Otolaryngology, Medical University of Warsaw. All patients were assessed with history of the disease, physical examination, hearing tests, computed tomography and/or magnetic resonance imaging, electronystagmography. Cases were observed in the direction of potential complications and recurrences. Neurinoma of the facial nerve occurred in the vertical segment (n=2), facial nerve geniculum (n=1) and the internal auditory canal (n=4). The symptoms observed in patients were analyzed: facial nerve paresis (n=3), hearing loss (n=2), dizziness (n=1). Magnetic resonance imaging and computed tomography allowed to confirm the presence of the tumor and to assess its staging. Schwannoma of the facial nerve has been surgically removed using the middle fossa approach (n=5) and by antromastoidectomy (n=2). Anatomical continuity of the facial nerve was achieved in 3 cases. In the twelve months after surgery, facial nerve paresis was rated at level II-III° HB. There was no recurrence of the tumor in radiological observation. Facial nerve neurinoma is a rare tumor. Currently surgical techniques allow in most cases, the radical removing of the lesion and reconstruction of the VII nerve function. The rate of recurrence is low. A tumor of the facial nerve should be considered in the differential diagnosis of nerve VII paresis. Copyright © 2013 Polish Otorhinolaryngology - Head and Neck Surgery Society.

To learn whether high school students searching health care information believe they are using evidence-based sites and to understand their topics of interest, frequently navigated sites, and trust/confidence in the credibility of information found. Cross-sectional. Students at a private high school answered an anonymous survey inquiring about their belief that they were using evidence-based sites, topics of interest, search engines of choice, and their trust in information obtained. Descriptive statistics and multivariate analysis of variance were used to compare trends across grade levels. Of 705 students enrolled, 24.7% were absent or declined to participate. For the remaining students, 497 completed the surveys, representing a response rate of 70.5% (497/705) and a participation rate of 93.6% (497/531). Overall, 82% of students communicated that they believed they were using evidence-based sources when searching for health information (p information, and 43% investigated specific medical conditions; topics related to skin and acne were researched significantly more often (p information they learn from the Internet. We found it chilling that less than half of students obtained their information from a Web site with health care professionals' oversight.

  1. 2010 American Conference on Neutron Scattering (ACNS 2010)

    2011-06-17

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

    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.

    Ethyl acetate and methanol extracts of 18 Thai medicinal plants were investigated for their antibacterial activity against Propionibacterium acnes, Stapylococcus aureus, and S. epidermidis. Thirteen plant extracts were capable of inhibiting the growth of P. acnes and S. epidermidis, while 14 plant extracts exhibited an inhibitory effect on S. aureus. Based on the broth dilution method, the ethyl acetate extract of Alpinia galanga (L.) Wild. (Zingiberaceae) rhizome showed the strongest antibacterial effect against P. acnes, with minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of 156.0 and 312.0 microg/mL, respectively. On the basis of bioassay-guided purification, the ethyl acetate extract was isolated to afford the antibacterial active compound, which was identified as 1'-acetoxychavicol acetate (1'-ACA). 1'-ACA had a strong inhibitory effect on P. acnes with MIC and MBC values of 62.0 and 250.0 microg/mL, respectively. Thus, 1'-ACA was used as an indicative marker for standardization of A. galanga extract using high performance liquid chromatography. These results suggest that A. galanga extract could be an interesting agent for further studies on an alternative treatment of acne.

    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.

    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.

    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.

    Acne vulgaris is a skin disease with a multifactorial and complex pathology. While several twin studies have estimated that acne has a heritability of up to 80%, the genomic elements responsible for the origin and pathology of acne are still undiscovered. Here we performed a twin-based structural equation model, using available data on acne severity for an Australian sample of 4,491 twins and their siblings aged from 10 to 24. This study extends by a factor of 3 an earlier analysis of the genetic factors of acne. Acne severity was rated by nurses on a 4-point scale (1 = absent to 4 = severe) on up to three body sites (face, back, chest) and on up to three occasions (age 12, 14, and 16). The phenotype that we analyzed was the most severe rating at any site or age. The polychoric correlation for monozygotic twins was higher (r MZ = 0.86, 95% CI [0.81, 0.90]) than for dizygotic twins (r DZ = 0.42, 95% CI [0.35, 0.47]). A model that includes additive genetic effects and unique environmental effects was the most parsimonious model to explain the genetic variance of acne severity, and the estimated heritability was 0.85 (95% CI [0.82, 0.87]). We then conducted a genome-wide analysis including an additional 271 siblings - for a total of 4,762 individuals. A genome-wide association study (GWAS) scan did not detect loci associated with the severity of acne at the threshold of 5E-08 but suggestive association was found for three SNPs: rs10515088 locus 5q13.1 (p = 3.9E-07), rs12738078 locus 1p35.5 (p = 6.7E-07), and rs117943429 locus 18q21.2 (p = 9.1E-07). The 5q13.1 locus is close to PIK3R1, a gene that has a potential regulatory effect on sebocyte differentiation.

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.

    Gaining better insight into the etiology and pathogenesis of recurrent facial nerve neuritis requires the use of an appropriate imaging modality of examination. This is retrospective analysis of 106 patients with recurrent n. facialis neuritis, studied by conventional x-ray methods, including: segment roentgenography according to Schuller, Stenverse, Biezalski (in children), and hypocyloidal directly enlarged polytomography, with emphasis laid on their role in the diagnostic algorithm of study. Assessment is done of the Fallopian canal width and course, with a special reference to adjacent bony structures, having essential practical bearing on planning interventions for decompression of the nerve and chronic otomastoiditis treatment. In 30 % of the patients are observed inflammatory changes in the parafacial bony structures as an expression of inflammatory otogenic etiology of recurrent n. facialis neuritis, and in 7 % - eburneization of bony structures. The symptom of improved Fallopian canal visibility is documented in cases presenting chronic inflammatory processes involving parafacial cellular structures. (author)

    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.

    Background: Acne vulgaris, a common human skin condition, is an inflammatory disease characterized by comedones, papules, nodules and possibly scarring. This study aimed to evaluate the efficacy of a combination of 5% dapsone gel plus oral isotretinoin in the treatment of acne vulgaris. Materials and Methods: A randomized, placebo-controlled, study was carried out on patients with moderate to severe acne. The patients were randomly divided in two groups: (dapsone gel and vehicle gel). All Patients were administered oral isotretinoin 20 mg daily and topical gel twice a day for 8 weeks. The Global Acne Assessment Score (GAAS), the number lesions and side-effects were documented at base line and weeks 4, 8 and 12. Results: A total of 58 patients (age range: 18-25 years) were included in our study. The number of lesions was significantly lower in the dapsone-treated group at all follow-up visits (P < 0.001). The mean GAAS score in the dapsone-treated group and in the Placebo-treated group decreased, but there was no statistical difference in two groups (P < 0.001). The side-effects on the dapsone-treated group were a mild burning sensation in 7 patients (24.13%), mild erythema of the skin and mild dryness in 4 (13.79%) and 3 (10.34%) cases respectively (P < 0.001). In our study, adverse effects were common but they were minor and tolerable. No clinically significant changes in laboratory parameters were observed (P < 0.001). Conclusions: Dapsone gel was an effective medication for patients who received isotretinoin for acne vulgaris treatment resulting in a significant reduction of the number of lesions. PMID:25250291

    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.

    To describe the management of traumatic neuroma of the facial nerve in a child and literature review. Sixteen-month-old male subject. Radiological imaging and surgery. Facial nerve function. The patient presented at 16 months with a right facial palsy and was found to have a right facial nerve traumatic neuroma. A transmastoid, middle fossa resection of the right facial nerve lesion was undertaken with a successful facial nerve-to-hypoglossal nerve anastomosis. The facial palsy improved postoperatively. A traumatic neuroma should be considered in an infant who presents with facial palsy, even in the absence of an obvious history of trauma. The treatment of such lesion is complex in any age group but especially in young children. Symptoms, age, lesion size, growth rate, and facial nerve function determine the appropriate management.

    Although there are multiple case reports and small series concerning facial infiltrative lipomatosis, there is no composite radiological description of the condition. Radiological evaluation of facial infiltrative lipomatosis using plain film, sonography, CT and MRI. We radiologically evaluated four patients with facial infiltrative lipomatosis. Initial plain radiographs of the face were acquired in all patients. Three children had an initial sonographic examination to evaluate the condition, followed by MRI. One child had a CT and then MRI. One child had abnormalities on plain radiographs. Sonographically, the lesions were seen as ill-defined heterogeneously hypoechoic areas with indistinct margins. On CT images, the lesions did not have a homogeneous fat density but showed some relatively more dense areas in deeper parts of the lesions. MRI provided better delineation of the exact extent of the process and characterization of facial infiltrative lipomatosis. Facial infiltrative lipomatosis should be considered as a differential diagnosis of vascular or lymphatic malformation when a child presents with unilateral facial swelling. MRI is the most useful single imaging modality to evaluate the condition, as it provides the best delineation of the exact extent of the process. (orig.)

    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.

    Objective The aim of this systematic review was to identify patient-reported outcome (PRO) instruments used in research with children/youth with conditions associated with facial differences to identify the health concepts measured. Design MEDLINE, EMBASE, CINAHL, and PsycINFO were searched from 2004 to 2016 to identify PRO instruments used in acne vulgaris, birthmarks, burns, ear anomalies, facial asymmetries, and facial paralysis patients. We performed a content analysis whereby the items were coded to identify concepts and categorized as positive or negative content or phrasing. Results A total of 7,835 articles were screened; 6 generic and 11 condition-specific PRO instruments were used in 96 publications. Condition-specific instruments were for acne (four), oral health (two), dermatology (one), facial asymmetries (two), microtia (one), and burns (one). The PRO instruments provided 554 items (295 generic; 259 condition specific) that were sorted into 4 domains, 11 subdomains, and 91 health concepts. The most common domain was psychological (n = 224 items). Of the identified items, 76% had negative content or phrasing (e.g., "Because of the way my face looks I wish I had never been born"). Given the small number of items measuring facial appearance (n = 19) and function (n = 22), the PRO instruments reviewed lacked content validity for patients whose condition impacted facial function and/or appearance. Conclusions Treatments can change facial appearance and function. This review draws attention to a problem with content validity in existing PRO instruments. Our team is now developing a new PRO instrument called FACE-Q Kids to address this problem.

    Propionibacterium acnes (P. acnes), a Gram-positive anaerobic bacterium, is a commensal organism in human skin. Like human cells, the bacteria produce porphyrins, which exhibit fluorescence properties and make bacteria visible with a Wood's lamp. In this review, we compare the porphyrin biosynthesis in humans and P. acnes. Also, since P. acnes living on the surface of skin receive the same radiation exposure as humans, we envision that the changes in porphyrin profiles (the absorption spectra and/or metabolism) of P. acnes by radiation may mirror the response of human cells to radiation. The porphyrin profiles of P. acnes may be a more accurate reflection of radiation risk to the patient than other biodosimeters/biomarkers such as gene up-/down-regulation, which may be non-specific due to patient related factors such as autoimmune diseases. Lastly, we discuss the challenges and possible solutions for using the P. acnes response to predict the radiation risk.

    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.

    Chemical peeling with both alpha and beta hydroxy acids has been used to improve acne scarring with pigmentation. Lactic acid, a mild alpha hydroxy acid, has been used in the treatment of various dermatological indications but no study is reported in acne scarring with pigmentation. To evaluate the efficacy and safety of full strength pure lactic acid 92% (pH 2.0) chemical peel in superficial acne scarring in Indian skin. Seven patients, Fitzpatrick skin type IV-V, in age group 20-30 years with superficial acne scarring were enrolled in the study. Chemical peeling was done with lactic acid at an interval of 2 weeks to a maximum of four peels. Pre- and post-peel clinical photographs were taken at every session. Patients were followed every month for 3 months after the last peel to evaluate the effects. At the end of 3 months, there was definite improvement in the texture, pigmentation, and appearance of the treated skin, with lightening of scars. Significant improvement (greater than 75% clearance of lesions) occurred in one patient (14.28%), good improvement (51-75% clearance) in three patients (42.84%), moderate improvement (26-50% clearance) in two patients (28.57%), and mild improvement (1-25% clearance) in one patient (14.28%). © 2010 Wiley Periodicals, Inc.

    Full Text Available Abstract Background In consideration of patients seeking to use traditional Chinese medicine, an evidence-based potentiality for safe and effective use of herbal medicine and acupuncture in treatment of acne vulgaris has been suggested. However, despite common use of a combination of herbal medicine and acupuncture in clinical practice, the current level of evidence is insufficient to draw a conclusion for an interaction and efficacy of herbal medicine and acupuncture. Therefore, considering these methodological flaws, this study was designed to assess the interaction and efficacy of an available herbal medicine, Keigai-rengyo-to extract (KRTE, and acupuncture for treatment of acne using the 2 × 2 factorial design and the feasibility of a large clinical trial. Methods/Design A randomized, assessor single blinded, 2 × 2 factorial pilot trial will be conducted. Forty four participants with acne vulgaris will be randomized into one of four groups: waiting list group (WL, KRTE only group (KO, acupuncture only group (AO, and KRTE and acupuncture combined treatment group (KA. After randomization, a total of 8 sessions of acupuncture treatment will be performed twice a week in the AO- and KA groups, respectively. Patients in the KO- and KA groups will be prescribed KRTE 3 times a day at a dose of 7.4 g after meals for 4 weeks. The following outcome measurements will be used in examination of subjects: the mean percentage change and the count change of inflammatory and non-inflammatory acne lesions, the Skindex 29, visual analogue scale (VAS and investigator global assessment (IGA from baseline to the end of the trial.

    2015-09-01

    To document the skin colonization and deep tissue inoculation rates associated with arthroscopic shoulder surgery and how these rates differ with procedural and demographic factors. We prospectively recruited outpatient shoulder arthroscopy patients who agreed to participate and met the inclusion criteria from February 2013 to May 2014. All patients received routine antibiotic prophylaxis intravenously. Initial cultures were obtained before the skin preparation by swabbing the skin at the 3 standard portal sites: posterior, anterosuperior, and anterolateral. The skin preparation used 4% chlorhexidine scrub and 2% chlorhexidine gluconate/70% isopropyl alcohol paint applied to the entire shoulder. After completion of the arthroscopic procedure, a second culture was obtained through a cannula at the surgical site. All cultures were plated for 21 days using Brucella medium. We enrolled 51 patients over a 15-month period. Cultures showed a 72.5% Propionibacterium acnes superficial colonization rate: 46.1% of female and 81.6% of male patients (P = .027). We identified a deep culture-positive inoculation rate of 19.6%, all with positive P acnes skin colonization. No correlation could be made concerning diagnosis, procedure, suture anchor use, age, or sex. The rate of skin colonization with P acnes is high at arthroscopic portals, especially in men. Despite standard skin preparation and prophylactic antibiotics, the rate of deep tissue inoculation with P acnes in shoulder arthroscopy is much higher than the rate of infection reported in the literature. Shoulder arthroscopy introduces a significant amount of P acnes into the deep tissues. Copyright © 2015 Arthroscopy Association of North America. Published by Elsevier Inc. All rights reserved.

    2015-03-01

    Facial expressions convey emotions that form the foundation of interpersonal relationships, and many of these emotions promote and regulate our social linkages. Hence, the facial aging symptomatological analysis and the treatment plan must of necessity include knowledge of the facial dynamics and the emotional expressions of the face. This approach aims to more closely meet patients' expectations of natural-looking results, by correcting age-related negative expressions while observing the emotional language of the face. This article will successively describe patients' expectations, the role of facial expressions in relational dynamics, the relationship between facial structures and facial expressions, and the way facial aging mimics negative expressions. Eventually, therapeutic implications for facial aging treatment will be addressed. © 2015 Wiley Periodicals, Inc.

    2009-08-01

    Facial synkinesis (or synkinesia) (FS) occurs frequently after paresis or paralysis of the facial nerve and is in most cases due to aberrant regeneration of (branches of) the facial nerve. Patients suffer from inappropriate and involuntary synchronous facial muscle contractions. Here we describe two cases of sound-induced facial synkinesis (SFS) after facial nerve injury. As far as we know, this phenomenon has not been described in the English literature before. Patient A presented with right hemifacial palsy after lesion of the facial nerve due to skull base fracture. He reported involuntary muscle activity at the right corner of the mouth, specifically on hearing ringing keys. Patient B suffered from left hemifacial palsy following otitis media and developed involuntary muscle contraction in the facial musculature specifically on hearing clapping hands or a trumpet sound. Both patients were evaluated by means of video, audio and EMG analysis. Possible mechanisms in the pathophysiology of SFS are postulated and therapeutic options are discussed.

    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.

    2000-08-14

    The physical differences between facial expressions (e.g. fear) and a reference norm (e.g. a neutral expression) were altered to produce photographic-quality caricatures. In Experiment 1, participants rated caricatures of fear, happiness and sadness for their intensity of these three emotions; a second group of participants rated how 'face-like' the caricatures appeared. With increasing levels of exaggeration the caricatures were rated as more emotionally intense, but less 'face-like'. Experiment 2 demonstrated a similar relationship between emotional intensity and level of caricature for six different facial expressions. Experiments 3 and 4 compared intensity ratings of facial expression caricatures prepared relative to a selection of reference norms - a neutral expression, an average expression, or a different facial expression (e.g. anger caricatured relative to fear). Each norm produced a linear relationship between caricature and rated intensity of emotion; this finding is inconsistent with two-dimensional models of the perceptual representation of facial expression. An exemplar-based multidimensional model is proposed as an alternative account.

    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

    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.

    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.

    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.

    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 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.

    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.

Psychosocial is defined as the interrelation of social factors with an individual's thoughts and behavior. The assessment of the psychosocial impact of skin disease on a patient can help direct the dermatologists' treatment goals. To evaluate the psychosocial impact of skin disease, we conducted a review of the literature on three skin conditions with onsets at various stages of life: acne, vitiligo, and psoriasis. Methods: A PubMed search was conducted in March 2015 using the terms “psychosocial” AND “acne”, “psychosocial” AND “vitiligo”, and “psychosocial” AND “psoriasis”. The results were limited to articles published in English in the past 5 years studying patients of all ages. Results and their references were evaluated for relevance according to their discussion of psychosocial qualities in their patients and the validity of psychosocial assessments. The search for acne yielded 51 results, and eleven were found to be relevant; vitiligo yielded 30 results with ten found to be relevant; and psoriasis yielded 70 results with seven found to be relevant. Results: According to the articles evaluated, 19.2% of adolescent patients with acne were affected in their personal and social lives. Social phobia was present in 45% of patients with acne compared to 18% of control subjects. Race and sex played a role in self-consciousness and social perceptions of the disease. Vitiligo

    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)

    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.

    Acne patients are subject to different degree of psychosocial distress. The emotional impact of acne vulgaris due to disfigurement caused by the disease is undisputed. Most common reactions to the acne are depression and anxiety. The use of isotretinoin, one of the most effective options in acne treatment, increases depression symptoms. The aim of this study was to investigate the psychological status of the patients with moderate to severe acne and to compare patients treated with isotretinoin with patients treated with vitamin C. A total of 85 patients suffering from acne vulgaris were included in the study. The results of this study do not find a significant correlation between the use of isotretinoin and the psychological effects of the drug.

    We report here an unexpectedly robust ability of healthy human individuals ( n = 40) to recognize extremely distorted needle-like facial images, challenging the well-entrenched notion that veridical spatial configuration is necessary for extracting facial identity. In face identification tasks of parametrically compressed internal and external features, we found that the sum of performances on each cue falls significantly short of performance on full faces, despite the equal visual information available from both measures (with full faces essentially being a superposition of internal and external features). We hypothesize that this large deficit stems from the use of positional information about how the internal features are positioned relative to the external features. To test this, we systematically changed the relations between internal and external features and found preferential encoding of vertical but not horizontal spatial relationships in facial representations ( n = 20). Finally, we employ magnetoencephalography imaging ( n = 20) to demonstrate a close mapping between the behavioral psychometric curve and the amplitude of the M250 face familiarity, but not M170 face-sensitive evoked response field component, providing evidence that the M250 can be modulated by faces that are perceptually identifiable, irrespective of extreme distortions to the face's veridical configuration. We theorize that the tolerance to compressive distortions has evolved from the need to recognize faces across varying viewpoints. Our findings help clarify the important, but poorly defined, concept of facial configuration and also enable an association between behavioral performance and previously reported neural correlates of face perception.

This was a cross-sectional study with 286 randomly selected from Universiti Sains Malaysia (USM) Health Campus students (150 females and 136 males; 100 Malaysian Chinese, 100 Malaysian Malay and 86 Malaysian Indian), with the mean age of 21.54 ± 1.56 (Age range, 18-25). Facial indices obtained from direct facial measurements were used for the classification of facial shape into short, ideal and long. A validated structured questionnaire was used to assess subjects' evaluation of their own facial appearance. The mean facial indices of Malaysian Indian (MI), Malaysian Chinese (MC) and Malaysian Malay (MM) were 1.59 ± 0.19, 1.57 ± 0.25 and 1.54 ± 0.23 respectively. Only MC showed significant sexual dimorphism in facial index (P = 0.047; Pmean score of 2.18 ± 0.97 for overall impression and 2.15 ± 1.04 for facial parts, compared to MM and MI, with mean score of 1.80 ± 0.97 and 1.64 ± 0.74 respectively for overall impression; 1.75 ± 0.95 and 1.70 ± 0.83 respectively for facial parts. 1) Only 17.1% of Malaysian facial proportion conformed to the golden ratio, with majority of the population having short face (54.5%); 2) Facial index did not depend significantly on races; 3) Significant sexual dimorphism was shown among Malaysian Chinese; 4) All three races are generally satisfied with their own facial appearance; 5) No significant association was found between golden ratio and facial evaluation score among Malaysian population.

    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.

    Conclusions: the association between acne and smoke shows an increased risk (OR=7.26 with a statistically significant CI. Moreover, people ≥ 18 years of age have twice the risk compared to persons < 18 years of age (OR=2.31.

    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

Late nocifensive behavior was significantly depressed in GluR2 delta7 KI and GluR3 delta7 KI mice. In addition, the number of pERK-immunoreactive (IR cells was significantly decreased bilaterally in the Vi/Vc, Vc and C1/C2 in GluR2 delta7 KI and GluR3 delta7 KI mice compared to wild-type mice at 40 min after formalin injection, and was also significantly smaller in GluR3 delta7 KI compared to GluR2 delta7 KI mice. The number of Fos protein-IR cells in the ipsilateral Vi/Vc, Vc and C1/C2 was also significantly smaller in GluR2 delta7 KI and GluR3 delta7 KI mice compared to wild-type mice 40 min after formalin injection. Nociceptive neurons functionally identified as wide dynamic range neurons in the Vc, where pERK- and Fos protein-IR cell expression was prominent, showed significantly lower spontaneous activity in GluR2 delta7 KI and GluR3 delta7 KI mice than wild-type mice following formalin injection. These findings suggest that GluR2 and GluR3 trafficking is involved in the enhancement of Vi/Vc, Vc and C1/C2 nociceptive neuronal excitabilities at 16-60 min following formalin injection, resulting in orofacial inflammatory pain.

    The Gram-positive, anaerobic/aerotolerant bacterium Cutibacterium acnes is a commensal of healthy human skin; it is subdivided into six main phylogenetic groups or phylotypes: IA1, IA2, IB, IC, II and III. To decipher how far specific subgroups of C. acnes are involved in disease physiopathology, different molecular typing methods have been developed to identify these subgroups: i.e. phylotypes, clonal complexes, and types defined by single-locus sequence typing (SLST). However, as several molecular typing methods have been developed over the last decade, it has become a difficult task to compare the results from one article to another. Based on the scientific literature, the aim of this narrative review is to propose a standardized method to perform molecular typing of C. acnes, according to the degree of resolution needed (phylotypes, clonal complexes, or SLST types). We discuss the existing different typing methods from a critical point of view, emphasizing their advantages and drawbacks, and we identify the most frequently used methods. 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 molecular typing methods for C. acnes. This standardization will facilitate the comparison of results between one article and another, and also the interpretation of clinical data.

    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

  9. Plasma Pharmacokinetics of Polyphenols in a Traditional Japanese Medicine, Jumihaidokuto, Which Suppresses Propionibacterium acnes-Induced Dermatitis in Rats

    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.

    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.

    2016-01-01

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

    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.

    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.

    To evaluate the safety and efficacy of dapsone gel 5% in the treatment of acne when used in combination with adapalene gel 0.1%, benzoyl peroxide gel 4% or moisturizer. This was a twelve-week, randomized, double-blind study. Patients aged 12 years and older (n=301) applied dapsone gel twice daily and were randomly assigned (1:1:1) to one of three additional treatments, applied once daily. By week 12, dapsone gel combined with any of the three additional treatments reduced the mean number of inflammatory lesions. However, the authors did not detect a significant difference in the reduction of inflammatory lesions when dapsone was used in combination with adapalene gel or with benzoyl peroxide gel compared to the dapsone plus moisturizer combination group (P=0.052 for both versus moisturizer combination). Patients treated with dapsone gel combined with adapalene showed a significantly better response in reduction in non-inflammatory and total acne lesion count than those who received the moisturizer combination. Local adverse reactions in all three treatment groups were minimal and generally mild in severity. Dapsone gel in combination with adapalene gel or benzoyl peroxide gel is safe and well tolerated for the treatment of acne vulgaris.

    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

    Full Text Available Propionibacterium acnes, Staphylococcus epidermidis and Staphylococcus aureus have been recognized as the bacteria that are involved in the inflammatory process of acne, while oxidants and antioxidants are involved in the repair of cutaneous tissue affected. In this study an evaluation was made of the antibacterial effect by the agar diffusion and broth dilution method, the cytoprotective and antioxidant effect on 3T3 dermic fibroblast cells, treated with hydrogen peroxide and the scavenging capacity of free radicals was determined by the 2, 2-diphenyl-l-picrylhydrazyl (DPPH method as well as the Reducing Power of the ethanolic extracts of the leaves of the Machaerium floribundum. Minimal bactericidal concentrations (MBC were obtained against Propionibacterium acnes and Staphylococcus aureus of 5 mg/mL and 2 mg/mL, respectively. A cytoprotective effect of 111% was observed over the cellular viability of the fibroblasts at 10 μg/mL and an antioxidant effect of 92% over the viability of the fibroblasts treated with hydrogen peroxide at 25 μg/mL. A stimulation of 24% growth of fibroblasts at 50 μg/mL was evidenced. On the other hand a 93% scavenging activity of the DPPH free radical was shown for 100 μg/mL with a CI50 of 34 μg/mL. The reducing power was evidenced to be dependent on the concentration. The results obtained indicated that the ethanolic extract of Machaerium floribundum shows a good antibacterial activity against bacteria that induce acne and a high potential for scavenging of free radicals at relatively low concentrations.

    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

    1989-12-01

    Synopsis Capryloyl collagenic acid (Lipacide C8Co) has similar bacteriostatic activity in vitro to that of benzoyl peroxide towards the bacteria found in acne lesions (Staphylococcus aureus, Staphylococcus epidermidis and Propionibacterium acnes) (MIC between 1 and 4 mg ml(-1) for C8Co, and between 0.5 and 5 mg ml(-1) for benzoyl peroxide). The presence of Emulgine M8 did not affect the bacteriostatic activity of C8Co. A 4% w/v solution of C8Co (incorporating Emulgine M8) fulfilled the criteria for an antiseptic preparation as laid down by the French Pharmacopoeia (10th Edition), and had a spectrum 5 bactericidal activity according to the French Standard AFNOR NF T 72-151. The excellent cutaneous tolerance of capryloyl collagenic acid would indicate that an aqueous solution might be of value for topical treatment of the bacterial component of acne. Résumé Activité antibactérienne de l'acide capryloyl-collagénique vis à vis des bactéries impliquées dans l'etiologie de l'acné L'acide capryloyl-collagénique (Lipacide C8Co) et le peroxyde de benzoyle présentent une activité bactériostatique in-vitroéquivalente vis à vis des espèces bactériennes retrouvées au niveau des lésions acnéiques (Staphylococcus aureus, S. epidermidis et Propionibacterium acnes) (CMI comprise entre 1 et 4 mg ml(-1) pour le lipoaminoacide, et 0,5 et 5 mg ml(-1) pour le peroxyde de benzoyle). La mise en solution aqueuse de l'acide capryloyl-collagénique en présence d'Emulgine M8 ne modifie pas son activité bactériostatique.

    Full Text Available Background: Acne is the most common skin disease, affecting nearly 85% of the population as well as their lives. Acne can severely affect social and psychological functioning. Patients with acne may have anxiety, depression, decreased self-esteem, interpersonal difficulties, unemployment, social withdrawal, and even suicidal intent. Aims: The aim of this study was to evaluate the temperament and character inventory (TCI of patients with acne and to compare the results with those of healthy controls. Study Design: Case-control study Methods: The study population consisted of 47 patients with acne, and 40 healthy control subjects. All participants were instructed to complete a self-administered 240-item TCI and the Hospital Anxiety and Depression Scale. Results: In this study, the scores for the temperament properties Worry and pessimism (HA1 and Dependence (RD4 and the character properties Social acceptance (C1 and Integrated conscience (C5 were found to be higher in acne patients than in healthy controls (p<0.05. Compared to the controls, depression and anxiety scores were found to be markedly higher in the patients with acne. Acne type correlated positively with the Disorderliness (NS4 subscale of Novelty seeking (NS and anxiety. Additionally, acne type correlated negatively with the Attachment (RD3 subscale of Reward Dependence (RD, with the Transpersonal identification (ST2 and Spiritual acceptance (ST3 subscales of Self-Trancendence (ST, and with the Compassion (C4 subscale of Cooperativeness (C. Conclusion: Studies in this area may lead to the development of specific and focused interventions for TCI in patients with acne vulgaris. We suggest that the evaluation and treatment of acne should also include psychosomatic approaches in clinical practice.

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.

    Full Text Available This study aimed to investigate the association of facial proportion and its relation to the golden ratio with the evaluation of facial appearance among Malaysian population. This was a cross-sectional study with 286 randomly selected from Universiti Sains Malaysia (USM Health Campus students (150 females and 136 males; 100 Malaysian Chinese, 100 Malaysian Malay and 86 Malaysian Indian, with the mean age of 21.54 ± 1.56 (Age range, 18-25. Facial indices obtained from direct facial measurements were used for the classification of facial shape into short, ideal and long. A validated structured questionnaire was used to assess subjects' evaluation of their own facial appearance. The mean facial indices of Malaysian Indian (MI, Malaysian Chinese (MC and Malaysian Malay (MM were 1.59 ± 0.19, 1.57 ± 0.25 and 1.54 ± 0.23 respectively. Only MC showed significant sexual dimorphism in facial index (P = 0.047; P<0.05 but no significant difference was found between races. Out of the 286 subjects, 49 (17.1% were of ideal facial shape, 156 (54.5% short and 81 (28.3% long. The facial evaluation questionnaire showed that MC had the lowest satisfaction with mean score of 2.18 ± 0.97 for overall impression and 2.15 ± 1.04 for facial parts, compared to MM and MI, with mean score of 1.80 ± 0.97 and 1.64 ± 0.74 respectively for overall impression; 1.75 ± 0.95 and 1.70 ± 0.83 respectively for facial parts.1 Only 17.1% of Malaysian facial proportion conformed to the golden ratio, with majority of the population having short face (54.5%; 2 Facial index did not depend significantly on races; 3 Significant sexual dimorphism was shown among Malaysian Chinese; 4 All three races are generally satisfied with their own facial appearance; 5 No significant association was found between golden ratio and facial evaluation score among Malaysian population.

    Full Text Available OBJECTIVES: This study evaluated the effects of facial stimulation over the superficial muscles of the face in individuals with facial lipoatrophy associated with human immunodeficiency virus (HIV and with no indication for treatment with polymethyl methacrylate. METHOD: The study sample comprised four adolescents of both genders ranging from 13 to 17 years in age. To participate in the study, the participants had to score six or less points on the Facial Lipoatrophy Index. The facial stimulation program used in our study consisted of 12 weekly 30-minute sessions during which individuals received therapy. The therapy consisted of intra- and extra-oral muscle contraction and stretching maneuvers of the zygomaticus major and minor and the masseter muscles. Pre- and post-treatment results were obtained using anthropometric static measurements of the face and the Facial Lipoatrophy Index. RESULTS: The results suggest that the therapeutic program effectively improved the volume of the buccinators. No significant differences were observed for the measurements of the medial portion of the face, the lateral portion of the face, the volume of the masseter muscle, or Facial Lipoatrophy Index scores. CONCLUSION: The results of our study suggest that facial maneuvers applied to the superficial muscles of the face of adolescents with facial lipoatrophy associated with HIV improved the facial area volume related to the buccinators muscles. We believe that our results will encourage future research with HIV patients, especially for patients who do not have the possibility of receiving an alternative aesthetic treatment.

    Cosmetic compatibility in the treatment of acne is an important issue significantly impacting quality of life, but often overlooked, as dermatologists commonly recommended avoidance of cosmetic foundations when treating adult female patients. Fixed combinations of clindamycin/benzoyl peroxide are widely used in the treatment of acne, but little is known about the impact of their concomitant use with facial foundation. To assess the compatibility of clindamycin phosphate 1. 2%/benzoyl peroxide 3. 75% gel with foundation makeup for up to six hours after application. Twenty-nine female subjects applied makeup to their face after randomly applying clindamycin phosphate 1. 2%/benzoyl peroxide 3. 75% gel to one side of the face. Investigator and subject self- assessment included facial skin attributes, facial tolerability, and cosmetic compatibility post-application and at Hour 6; as well as cutaneous tolerability. No statistical difference was noted between the treated and untreated side of the face in terms of coverage, blotchiness, appearance, skin tone, or visual smoothness. Tolerability was excellent, with no erythema, edema, dryness, and peeling post-makeup application. For both the treated and untreated side, there was a slight lack of improvement in cosmetic appearance six hours post-makeup application. Clindamycin/benzoyl peroxide 3. 75% gel was shown to have excellent cosmetic compatibility with facial foundation.

    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.

    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.

    Propionibacterium acnes and Staphylococcus epidermidis have been recognized as pus-forming bacteria triggering an inflammation in acne. The present study was conducted to evaluate antimicrobial activities of Thai medicinal plants against these etiologic agents of acne vulgaris. Crude extracts were tested for antimicrobial activities by disc diffusion and broth dilution methods. The results from the disc diffusion method showed that 13 medicinal plants could inhibit the growth of Propionibacterium acnes. Among those, Senna alata, Eupatorium odoratum, Garcinia mangostana, and Barleria lupulina had strong inhibitory effects. Based on a broth dilution method, the Garcinia mangostana extract had the greatest antimicrobial effect. The MIC values were the same (0.039 mg/ml) for both bacterial species and the MBC values were 0.039 and 0.156 mg/ml against Propionibacterium acnes and Staphylococcus epidermidis, respectively. In bioautography assay, the Garcinia mangostana extract produced strong inhibition zones against Propionibacterium acnes. Antimicrobial activity from fractions of column chromatography revealed one of the active compounds in Garcinia mangostana could be mangostin, a xanthone derivative. Taken together, our data indicated that Garcinia mangostana had a strong inhibitory effect on Propionibacterium acnes and Staphylococcus epidermidis. Therefore, this plant would be an interesting topic for further study and possibly for an alternative treatment for acne.

    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.

    This paper reviews clinical neuropsychological studies that have indicated that the recognition of a person's identity and the recognition of facial expressions are processed by different cortical and subcortical areas of the brain. The fusiform gyrus, especially the right fusiform gyrus, plays an important role in the recognition of identity. The superior temporal sulcus, amygdala, and medial frontal cortex play important roles in facial-expression recognition. Both facial recognition and facial-expression recognition are highly intellectual processes that involve several regions of the brain.

    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.

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.

    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.

    2018-01-01

    Background: Propionibacterium acnes (P. acnes) is a microaerophilic anaerobic Gram-positive rod responsible for acne vulgaris. Although it is often considered to be a skin contaminant, it may act as a virulent agent in implant-associated infections. Conversely, spontaneous infectious processes have been rarely described. Case Description: Here, we describe a 43-year-old female with C1-C2 spondylodiscitis attributed to P. acnes infection. Despite long-term antibiotic treatment, computed tomography demonstrated erosion of the C1 and C2 vertebral complex that later warranted a fusion. One year postoperatively, the patient was asymptomatic. Conclusions: Clinical knowledge of P. acnes virulence in spontaneous cervical spondylodiscitis allows early diagnosis, which is necessary to prevent or reduce complications such as cervical deformity with myelopathy or mediastinitis.

    Acne keloidalis nuchae (AKN) is a chronic inflammatory disease involving hair follicles of the neck. It is a form of keloidal scarring alopecia that is often refractory to medical or surgical management. To evaluate the efficacy of Er:YAG laser in the treatment of AKN as compared to long pulsed Nd:YAG laser. This study was conducted on 30 male patients with AKN. Their ages ranged from 19 to 47 years with a mean age of 36.87 ± 7.8 years. Patients were divided randomly into two groups of 15 patients, each receiving six sessions of either Er:YAG or long-pulsed Nd:YAG laser therapy. A statistically significant decrease in the number of papules was detected at the end of therapy in both groups, with a mean of 91.8% improvement in the Er:YAG group versus 88% in the Nd:YAG group. A significant decrease in plaques count was detected only in the Er: YAG group while a significant decrease in plaques size and consistency was recorded in both groups. The Er: YAG laser proved to be a potentially effective and safe modality both in the early and late AKN lesions.

    2015-01-01

    Acne vulgaris is a chronic condition affecting more than 85% of adolescents and young adults. It is one of the most common diseases affecting humanity and its impact on quality of life (QoL) is important. The impact of acne on QoL in Indian patients remains undocumented. The study was undertaken to detect the impact of acne vulgaris and related factors that may influence the QoL. Materials and Methods: This was a hospital-based, prospective, cross-sectional, prestructured, questionnaire-based study done on 140 consenting individuals, who attended the Dermatology outpatient department. Acne vulgaris was graded using simple grading system. QoL was measured using a combination of skin disease-specific (Dermatological Life Quality Index (DLQI)) and acne-specific (Cardiff Acne Disability Index (CADI)) questionnaires. Results: Majority of our study population were students (103, 73.6%). Face (139, 99.3%) was the commonest site of acne and comedones 133, 95% were the commonest type of lesion. Most of the individuals 66, 47.1% were observed to have grade 1 acne. The mean DLQI score was 6.91 and the mean CADI score was 5.2. Association between the scores was statistically significant. Age, occupation, marital status, family, and treatment history played a role in affecting the QoL. Diet, smoking, and alcohol did not influence the QoL. Conclusion: Though acne had impact on patient's QoL, it was less severe in our study. It is important for health professionals to incorporate QoL measurements when managing acne patients to provide better and appropriate care. PMID:25657394

    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.

    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.

    Photodestruction of Propionibacterium acnes was investigated by broad-band near-ultraviolet light. The inactivation of the bacteria was found to be oxygen dependent, and without O 2 practically no photoinactivation occurred. D 2 O caused an increased inactivation (D 10 = 5 kJ/m 2 in D 2 O as compared to D 10 = 11 kJ/m 2 in normal water). Decreased temperature during illumination increased the ability to form colonies. The results are compared with corresponding results for other types of cells and the destruction mechanism is discussed. (orig.)

    Full Text Available Los abscesos cerebrales por Propionibacterium acnes son poco frecuentes. Es importante para el médico clínico la rápida identificación de este patógeno para la elección de una terapéutica antibiótica adecuada. En este caso se describe un paciente con una exéresis de un glioblastoma multiforme donde a los 9 meses se evidenció la existencia de una recidiva tumoral, se efectuó una extirpación tumoral subtotal y la colocación de implantes de quimioterapia en el lecho tumoral residual. Al cabo de un mes de esta reoperación presentó una lesión ocupante compatible con un absceso cerebral, motivo por el cual se realizó nueva craneotomía y drenaje del mismo. En los cultivos de las biopsias y del material purulento se aisló P. acnes como flora única. Para la identificación se realizaron pruebas bioquímicas y se aplicó el sistema API20A. Se determinó la concentración inhibitoria mínima (CIM a clindamicina, penicilina, amoxicilina y metronidazol, los valores de CIM (ug/ml obtenidos fueron: 0.250, 0.040, 0.023 y 256, respectivamente. El paciente recibió cefepime más metronidazol por vía endovenosa durante un período de 30 días y completó tratamiento con clindamicina por vía oral durante 60 días, dada la posible complicación ósea en el sitio de la infección. Luego de 8 meses de la intervención quirúrgica y el drenaje del absceso cerebral no hubo evidencia de signos clínicos de recidiva tumoral e infecciosa. P. acnes es un patógeno infrecuente como causal de abscesos cerebrales, sin embargo no se debe desestimar en muestras neuroquirúrgicas.Brain abscesses by Propionibacterium acnes are rare. The rapid identification of this pathogen is important in order to choice the appropriate antibiotic therapy. We describe the case of a patient with excision of a multiform glioblastoma who 9 months later presented a tumor recurrence. A subtotal tumor excision was made and implants chemotherapy were placed in the residual tumor

    CT and MR findings of nine cases with intra temporal facial nerve neuromas were described and compared with CT findings of 3 cases with facial nerve palsy and facial nerve canal erosion which may mimic facial nerve neuroma. The tympanic segment of the facial nerve was involved in 8 cases, mastoid segment in 7 cases and labyrinthine segment in 5 cases. The lesions were easily diagnosed with high resolution CT with bone algorithms by showing the expansion of bony structures along the course of the facial nerves. In 4 cases with large vertical segment tumors, extensive destruction of mastoid air cells and external auditory canals posed difficulty in making a diagnosis. Two out of 5 cases with labyrinthine segment involvement were presented as middle cranial fossa masses. MRI with enhancement was performed in 4 cases and was useful in characterizing the lesion as a tumor with its superior sensitivity to enhancement. Three cases of facial neuroma-mimicking lesion including post-inflammatory peri neural thickening, peri neural extension from parotid adenoid cystic carcinoma, and congenita; cholesteatoma showed irregular erosion or mild expansion of the facial nerve canal which may be helpful for differential diagnosis from neuromas.

    Skin disorders such as acne, which have significant cosmetic implications, can affect the self-perception of cutaneous body image. There are many scales which measure self-perception of cutaneous body image. We evaluated the use of a simple Cutaneous Body Image (CBI) scale to assess self-perception of body image in a sample of young Arab patients affected with acne. A total of 70 patients with acne answered the CBI questionnaire. The CBI score was correlated with the severity of acne and acne scarring, gender, and history of retinoids use. There was no statistically significant correlation between CBI and the other parameters - gender, acne/acne scarring severity, and use of retinoids. Our study suggests that cutaneous body image perception in Arab patients with acne was not dependent on variables like gender and severity of acne or acne scarring. A simple CBI scale alone is not a sufficiently reliable tool to assess self-perception of body image in patients with acne vulgaris.

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

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

    Ablative carbon dioxide (CO(2) ) fractional resurfacing is a promising therapeutic intervention for the treatment of acne scars, although this technique is associated with prolonged surgical site erythema and edema, which may affect the daily lives of patients. Autologous platelet-rich plasma (PRP) is known to enhance wound healing and has applications in many areas of medicine. To evaluate the synergistic effects of autologous PRP with CO(2) fractional resurfacing for acne scars. A split-face trial was conducted in 14 Korean participants with acne scars. All participants received one session of ablative CO(2) fractional resurfacing. Immediately after resurfacing, facial halves were randomly assigned to receive treatment with autologous PRP injections on one side (experimental side) and normal saline injections on the other side (control side). The participants were monitored for degree of recovery and resurfacing-associated adverse events, including prolonged erythema, edema, and other effects on days 0, 2, 4, 6, 8, 15, and 30. The intensity of erythema was objectively measured using a chromometer at the same time intervals. After one additional treatment session using the same protocol, two independent dermatologists evaluated clinical improvement using a quartile grading scale. All participants completed the study. Erythema on the experimental side improved faster than on the control side and was significantly less at day 4 (p=.01). This difference was confirmed using a chromometer (p=.049). Total duration of erythema was an average of 10.4±2.7 days on the control side and 8.6±2.0 days on the experimental side (p=.047). Edema also improved faster on the experimental side than on the control side. The total duration of edema was an average of 7.1±1.5 days on the control side and 6.1±1.1 days on the experimental side (p=.04). Participants were also assessed for duration of post-treatment crusting, with a mean of 6.8±1.0 days on the control side and 5.9±1

    We present a very rare case of a patient with an infected subdural hematoma due to Propionibacterium acnes. A 63-year-old male complained of dizziness and was admitted to our hospital. He had a history of left chronic subdural hematoma due to a traffic accident, which had been conservatively treated. Physical, neurological and laboratory examinations revealed no definite abnormality. Plain CT scan demonstrated a hypodense crescentic fluid collection over the surface of the left cerebral hemisphere. The patient was diagnosed with chronic subdural hematoma and underwent burr hole surgery three times and selective embolization of the middle meningeal artery, but the lesion easily recurred. Repeated culture examinations of white sedimentation detected P. acnes. Therefore, he underwent craniotomy surgery followed by intravenous administration of antibiotics. The infected subdural hematoma was covered with a thick, yellowish outer membrane, and the large volume of pus and hematoma was removed. However, the lesion recurred again and a low-density area developed in the left frontal lobe. Craniotomy surgery was performed a second time, and two Penrose drainages were put in both the epidural and subdural spaces. Subsequently, the lesions completely resolved and he was discharged without any neurological deficits. Infected subdural hematoma may be refractory to burr hole surgery or craniotomy alone, in which case aggressive treatment with craniotomy and continuous drainage should be indicated before the brain parenchyma suffers irreversible damage.

    Full Text Available The aim of this study was to explore the effects of motherwort alkaloids on rat ear acne. The rats that were administered high, medium, and low doses of motherwort alkaloids, tanshinone capsules, a model and a control group. Each group of rats was subjected to gavage once daily for 14 consecutive days. On the first day of testing, the control and model groups were administered an intradermal auricle injection of sterilized saline solution and the remaining groups were administered an intradermal auricle injection of Staphylococcus epidermidis in addition to the gavage. The thicknesses of the rats’ auricles were measured for five consecutive days following the injections. Anticoagulated blood was used for erythrocyte rheology index measurement. In addition, the entire ear of each rat was removed for morphological examination. Compared to the model group, the group administered motherwort alkaloids exhibited significantly reduced swelling, improved localized auricle proliferation, and reduced blood viscosity. This result suggests motherwort alkaloids are effective in rat ear acne.

    Frozen shoulder has not previously been shown to be associated with infection. The present study set out to confirm the null hypothesis that there is no relationship between infection and frozen shoulder using two modern scientific methods, extended culture and polymerase chain reaction (PCR) for bacterial nucleic acids. A prospective cohort of 10 patients undergoing arthroscopic release for stage II idiopathic frozen shoulder had two biopsies of tissue taken from the affected shoulder joint capsule at the time of surgery, along with control biopsies of subdermal fat. The biopsies and controls were examined with extended culture and PCR for microbial nucleic acid. Eight of the 10 patients had positive findings on extended culture in their shoulder capsule and, in six of these, Propionibacterium acnes was present. The findings mean that we must reject the null hypothesis that there is no relationship between infection and frozen shoulder. More studies are urgently needed to confirm or refute these findings. If they are confirmed, this could potentially lead to new and effective treatments for this common, painful and disabling condition. Could P. acnes be the Helicobacter of frozen shoulder?

    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 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.)

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

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

    Recent evidence suggests that acne vulgaris begins as an inflammation in and around the sebaceous gland and alterations in the lipid content of sebum, which drive hyperproliferation and increased desquamation of keratinocytes within sebaceous follicles. This prevents sebum drainage, causing the formation of microcomedones, which spontaneously regress or become acne lesions when the pilosebaceous unit is further blocked by the accumulation of corneocytes. These conditions are favourable for the proliferation of Propionibacterium acnes, which further aggravates acne by enhancing abnormal desquamation, sebum production and inflammation. Also, skin fragility due to inflammation or irritation by anti-comedogenic agents can worsen the situation. Rhealba(®) Oat plantlet extract (Pierre Fabre Dermo Cosmetique) soothes and restores fragile skin in acne by reducing inflammation and inhibits bacterial adhesion of Propionibacterium acnes. Cosmeceuticals combining Rhealba(®) Oat plantlet extract and hydro-compensating actives, which are available with or without anti-comedogenic hydroxy acids, provide a balanced, multifaceted approach for acne patients. © 2014 European Academy of Dermatology and Venereology.

    Acne vulgaris affects about 85% of teenagers and may continue to adulthood. There are about two million visits to physicians per year for teenagers and the direct cost of acne treatment in the US exceeds $1 billion per year. A wide variety of treatment regimens exist for acne vulgaris including benzoil peroxide, retinoids, isotretinoids, keratolytic soaps, alpha hydroxy acids, azelaic acid, salicilic acid as well as hormonal, anti-androgen or antiseborrheic treatments. However, none of these methods is free of side effects and their exact role in therapy is not clear. In this paper apart from presenting the possible causes of acne vulgaris and its available drugs, recently published papers about medicinal plants used in the treatment of acne vulgaris were reviewed. Consumption of alternative and complementary medicine, including medicinal plants, is increasing and is common amongst patients affected by acne and infectious skin diseases. Medicinal plants have a long history of use and have been shown to possess low side effects. These plants are a reliable source for preparation of new drugs. Many plants seem to have inhibitory effects on the growth of bacteria, fungi and viruses in vitro. However, there are a few clinical evidences about the effectiveness and safety of these plants in the treatment of acne and other skin infections.

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

    Acne vulgaris is an extremely common condition affecting the pilosebaceous unit of the skin and characterized by presence of comedones, papules, pustules, nodules, cysts, which might result in permanent scars. Acne vulgaris commonly involve adolescents and young age groups. Active acne vulgaris is usually associated with several complications like hyper or hypopigmentation, scar formation and skin disfigurement. Previous studies have targeted the efficiency and safety of local and systemic agents in the treatment of active acne vulgaris. Superficial chemical peeling is a skin-wounding procedure which might cause some potentially undesirable adverse events. This study was conducted to review the efficacy and safety of superficial chemical peeling in the treatment of active acne vulgaris. It is a structured review of an earlier seven articles meeting the inclusion and exclusion criteria. The clinical assessments were based on pretreatment and post-treatment comparisons and the role of superficial chemical peeling in reduction of papules, pustules and comedones in active acne vulgaris. This study showed that almost all patients tolerated well the chemical peeling procedures despite a mild discomfort, burning, irritation and erythema have been reported; also the incidence of major adverse events was very low and easily manageable. In conclusion, chemical peeling with glycolic acid is a well-tolerated and safe treatment modality in active acne vulgaris while salicylic acid peels is a more convenient for treatment of darker skin patients and it showed significant and earlier improvement than glycolic acid.

    The trigeminal nerve is the largest of the cranial nerves. It provides sensory input from the face and motor innervation to the muscles of mastication. The facial nerve is the cranial nerve with the longest extracranial course, and its main functions include motor innervation to the muscles of facial expression, sensory control of lacrimation and salivation, control of the stapedial reflex and to carry taste sensation from the anterior two-thirds of the tongue. In order to be able adequately to image and follow the course of these cranial nerves and their main branches, a detailed knowledge of neuroanatomy is required. As we are dealing with very small anatomic structures, high resolution dedicated imaging studies are required to pick up normal and pathologic nerves. Whereas CT is best suited to demonstrate bony neurovascular foramina and canals, MRI is preferred to directly visualize the nerve. It is also the single technique able to detect pathologic processes afflicting the nerve without causing considerable expansion such as is usually the case in certain inflammatory/infectious conditions, perineural spread of malignancies and in very small intrinsic tumours. Because a long course from the brainstem nuclei to the peripheral branches is seen, it is useful to subdivide the nerve in several segments and then tailor the imaging modality and the imaging study to that specific segment. This is particularly true in cases where topographic diagnosis can be used to locate a lesion in the course of these nerves. (orig.)

This is particularly true in cases where topographic diagnosis can be used to locate a lesion in the course of these nerves. (orig.)

    The association between acne and food has been evaluated with inconsistent results. We enrolled 783 patients with acne and 502 control subjects. For the patients with acne, blood tests for insulin, insulin-like growth factor-1 (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3), post prandial 2 hours blood glucose (PP2), and dehydroepiandrosterone sulphate (DHEAS) were performed. The acne patients were divided into an "aggravated by food" group (AF) and a "not aggravated by food" group (NAF). All participants were asked to fill out a questionnaire. The frequency of vegetables (yellow, green leafy, cruciferous) (P = .001) and fish (white flesh and green fish, blue tuna) ((P = .03) intake was significantly higher in the control group than in the acne group. Intake of instant noodles (P = .01), junk food (P = .002), carbonated drinks (P = .005), snacks (P = .001), processed cheeses (P = .04), pork (braised) (P = .02), pork (roast) (P < .001), chicken (fried) (P = .001), chicken (stewed) (P = .001), nuts (P = .002) and seaweed (P = .003) were significantly higher in the acne patients than in the controls. Intake of roast pork (P = .02), fried chicken (P < .02), and nuts (P = .03) was significantly higher in the AF than NAF. In addition, the regularity of inter-meal intervals (P < .001) and breakfast intake (P < .001) were significantly lower in the acne patients. IGF-1 and IGFBP-3 showed sexual differences. This study also showed that a high glycemic load diet, dairy food intake, high fat diet, and iodine in Korean foods appear to play a role in acne exacerbation. In addition, irregular dietary patterns were found to aggravate acne.

    The research evaluating adipokines are very few in patients with acne vulgaris. The hypothesis that hyperinsulinemic and high glycemic index diet plays a role in the pathogenesis of acne is still controversial. In this study, we aimed to evaluate adipokines such as leptin (L), adiponectin (A), ghrelin and A levels, and A/L rates that indicate insulin resistance in nonobese patients with severe acne vulgaris. Thirty patients who are nonobese with moderate acne vulgaris, aged 18 to 25 years, and 15 age-sex compatible controls were included in our study. The acne lesions were assessed using the Global Acne Grading Scale (GAGS). All participants were evaluated for the parameters that may affect the metabolism of serum L, A, and ghrelin levels in blood, and their body mass index were calculated. The significance level was determined as p ≤ 0.05. Of the 30 patients, 17 were women and 13 were men. The mean age was 20.60 years and the mean duration of the disease were 2.8 years. All of patients had moderate acne vulgaris (GAGS 19-30). Of the 15 controls, 11 were women and 4 were men. The mean age was 21.20 years. There were not a statistically significant difference in L, ghrelin, A levels, and A/L ratio between the two groups. Adipokines may have a role in the pathogenesis of acne vulgaris. L, A, ghrelin, and insulin resistance may not participate in the responsible mechanisms in nonobese patients with moderate acne vulgaris. © The Author(s) 2016.

    Dermatological diseases, among which acne vulgaris, have psychological impact on the affected generating feelings of guilt, shame and social isolation. To compare quality of life, self-esteem and other psychosocial variables amongst adolescents with and without acne vulgaris, and between levels of severity. Cross-sectional observational study in a sample of 355 high school students from the city of João Pessoa. Data collection was performed with questionnaires and clinical-dermatological evaluation. The primary variables were the incidence of AV; quality of life, set by the Children's Dermatology Quality of Life Index and Dermatology Quality of Life Index; and self-esteem, measured by the Rosenberg Self-Esteem Scale. For calculation of statistical tests, we used the SPSS 20.0 software, considering p=0.05. The sample, with an average age of 16, showed 89.3% prevalence of acne vulgaris. The most prevalent psychosocial issue was "afraid that acne will never cease", present in 58% of affected youth. The median score of Quality of Life in Children's Dermatology Index was different amongst students with and without acne vulgaris (p=0.003), as well as the Quality of Life in Dermatology (p=0.038) scores, so that students with acne vulgaris have worse QoL. There was a correlation between the severity of acne vulgaris and worse quality of life. Self-esteem was not significantly associated with the occurrence or severity of acne vulgaris. acne vulgaris assumes significance in view of its high prevalence and the effect on quality of life of adolescents, more severe at the more pronounced stages of disease (pacne vulgaris should be valued in the management of patients with this condition.

Background: With emerging use of ME-health technology, there is a growing interest in evaluating the effectiveness of the tools on medication adherence. Examples of ME-health technology-based tools include text message-based pill reminders and Web-based patient education. Methods: MEDLINE, Cochrane Library, and Web of Science were searched for articles on adherence to acne treatment published through November 2013. A combination of search terms such as "acne" and "adherence" or "compliance" were used. Results: Adherence to oral acne medication was higher than for topical acne medication. The frequency of office visits was also an influencing factor for acne treatment adherence. The telephone-based reminders on a daily basis did not improve acne patients' medication adherence, whereas the Web-based educational tools on a weekly basis had a positive effect on medication adherence in acne treatment. Conclusion: In using ME-health interventions, factors such as medication dosage forms, frequency of intervention, and patients' preferences should be taken into consideration. Developing disease-specific text message reminders may be helpful to increase adherence rates. In addition, a combination of text message reminders with another type of intervention may improve medication adherence.

    The role of growth hormone, insulin, and insulin-like growth factor-1 (IGF-1) in the development of acne is incompletely understood. To study the effect of the absence of IGF-1 and its pharmacologic replacement on the occurrence of acne vulgaris. Laron syndrome (LS) is characterized by congenital IGF-1 deficiency. The study group consisted of 21 patients with classical LS, who underwent puberty: 13 (8 male, 5 female) untreated and under regular follow-up until age 20?48 years; and 8 (2 male, 6 female) treated with IGF-1 (70-200 μg/kg/day), including 6 adults (2 male, treated at age 14.5-29 years and 4 female, treated at age 30-37 years) and 2 adolescents (2 female, treated at age 3.5-16 years). The medical files were reviewed for occurrence of acne and the corresponding sex hormone levels, and the findings were compared between the treated and untreated patients. Puberty was delayed in all untreated patients. Only one patient had slight acne at age 22 years, when he reached full puberty. Among the 2 IGF-1 treated male patients, none acquired acne. Among the 6 treated female patients, 3 had signs of hyperandrogenism (oligo-amenorrhea) and acne during IGF-1 over-dosage. On reduction of the IGF-1 dose (to 50 μg/kg/day) or cessation of treatment, the acne disappeared in all 3 patients. This study demonstrates for the first time that serum IGF-1 deficiency prevents the occurrence of acne. The findings suggest that an interaction between IGF-1 and androgens is necessary for the development of acne. © 2010 The Authors.

    Propionibacterium acnes (P acnes) has been linked to chronic infections in shoulder surgery. It was recently observed during first-time shoulder surgery in healthy patients at a rate between 36% and 56%. Male gender and the anterolateral approach were reported risk factors. Because the skin biology greatly differs, we aimed to correlate skin complaints with P acnes-positive intraoperative cultures from different tissue layer samples in patients undergoing shoulder surgery for the first time. Intraoperative samples (1 skin, 1 superficial, 1 deep tissue, and 1 control sample) from 112 patients (70 men, 42 women; aged 59.2 years) were cultured. The association between the presence of P acnes in the deep or superficial tissue, or both, and 10 items of a validated preoperative questionnaire for skin pathology was explored. The cultures were positive for P acnes in 38.4% (n = 43) of the cases. Skin samples were positive for P acnes in 8% (n = 9), superficial samples were positive in 23% (n = 26), and deep samples were positive in 30% (n = 34). Self-reported "loss of hair" was significantly negatively associated with the presence of P acnes in the superficial or deep tissue sample (P = .00028). Patients who report having "loss of hair" show fewer P acnes-positive cultures in intraoperative tissue samples taken during open shoulder surgery. Whether this subgroup is at a lesser risk for P acnes infections remains to be substantiated. Basic Science Study; Microbiology.

  1. Does facial resemblance enhance cooperation?

    Directory of Open Access Journals (Sweden)

    Trang Giang

    Full Text Available Facial self-resemblance has been proposed to serve as a kinship cue that facilitates cooperation between kin. In the present study, facial resemblance was manipulated by morphing stimulus faces with the participants' own faces or control faces (resulting in self-resemblant or other-resemblant composite faces. A norming study showed that the perceived degree of kinship was higher for the participants and the self-resemblant composite faces than for actual first-degree relatives. Effects of facial self-resemblance on trust and cooperation were tested in a paradigm that has proven to be sensitive to facial trustworthiness, facial likability, and facial expression. First, participants played a cooperation game in which the composite faces were shown. Then, likability ratings were assessed. In a source memory test, participants were required to identify old and new faces, and were asked to remember whether the faces belonged to cooperators or cheaters in the cooperation game. Old-new recognition was enhanced for self-resemblant faces in comparison to other-resemblant faces. However, facial self-resemblance had no effects on the degree of cooperation in the cooperation game, on the emotional evaluation of the faces as reflected in the likability judgments, and on the expectation that a face belonged to a cooperator rather than to a cheater. Therefore, the present results are clearly inconsistent with the assumption of an evolved kin recognition module built into the human face recognition system.

    Human beings exploit emotions comprehensively for conveying messages and their resolution. Emotion detection and face recognition can provide an interface between the individuals and technologies. The most successful applications of recognition analysis are recognition of faces. Many different techniques have been used to recognize the facial expressions and emotion detection handle varying poses. In this paper, we approach an efficient method to recognize the facial expressions to track face points and distances. This can automatically identify observer face movements and face expression in image. This can capture different aspects of emotion and facial expressions.

    As with the treatment of all facial deformities, orthodontic pre-surgical preparation for facial asymmetry should aim at correcting severe occlusal discrepancies not solely on the basis of a narrow occlusal analysis but also in a way that will not disturb the proposed surgical protocol. In addition, facial asymmetries require specific adjustments, difficult to derive and to apply because of their inherent atypical morphological orientation of both alveolar and basal bony support. Three treated cases illustrate different solutions to problems posed by pathological torque: this torque must be considered with respect to proposed surgical changes, within the framework of their limitations and their possible contra-indications.

Theprimary use for these will be the reanimation of paralysedor atrophied muscles in sufferers of non-recoverableunilateral facial paralysis.MethodThe prosthetic solution described in this paper is based onsensing muscle motion of the contralateral healthy musclesand replicating that motion across a patient’s paralysed sideof the face, via solid state and thin film actuators. Thedevelopment of this facial prosthetic device focused onrecreating a varying intensity smile, with emphasis ontiming, displacement and the appearance of the wrinklesand folds that commonly appear around the nose and eyesduring the expression.An animatronic face was constructed with actuations beingmade to a silicone representation musculature, usingmultiple shape-memory alloy cascades. Alongside theartificial muscle physical prototype, a facial expressionrecognition software system was constructed.

    An open-label, randomized, multicenter study was conducted to evaluate the safety and efficacy of long-term use of 2.5% and 5% benzoyl peroxide (BPO) gels administrated once daily for 52 weeks to Japanese patients with acne vulgaris. The efficacy of the study drugs was evaluated by counting inflammatory lesions and non-inflammatory lesions. Safety was evaluated based on adverse events, local skin tolerability scores and laboratory test values. In total, 458 subjects were included in the efficacy and safety analyses. The total lesion count, the efficacy end-point, was similarly changed both in the 2.5% and 5% BPO groups over the course of the study. The median rates of reduction from baseline to week 12 were approximately 65%. Thereafter, the counts were maintained at a reduced level without increasing until week 52. The median rates at week 52 were approximately 80%. Similar trends were observed for inflammatory and non-inflammatory lesion counts. Bacteriological evaluation indicated similar distribution of the minimum inhibitory concentration of each of the antibacterial drugs against Propionibacterium acnes between the values at baseline and at week 52, suggesting that long-term use did not result in changes in the drug sensitivity. The incidence of adverse events was 84.0% in the 2.5% BPO group and 87.2% in the 5% BPO group. Many of the adverse events occurred within the first month and were mild or moderate in severity and transient. The results suggest that both 2.5% and 5% BPO gels are effective and safe for long-term treatment of patients with acne vulgaris. © 2017 The Authors.

    Full Text Available Acne is one of the most common skin disease in young adults and occurs in 85% of boys and girls. The disease is characterized by progressive course of the formation of psycho-emotional disorders, mainly depression row in about half of patients. Installed heredity is almost 80% of first-degree relatives of patients with acne. In patients with positive family history of acne the disease occurs earlier and course harder. The aim of the study – is to determine the impact of acne on psycho-emotional status in patients. Materials and methods. We examined 78 patients with severe and moderate acne. All patients were questioned by questionnaire CADI (Cardiff Acne Disability Index. Results. Among the surveyed men with moderate acne average value was 6, median – 6, mode – 6; in men with severe acne course average value was 8.6, median – 9.5, mode – 10. Among women surveyed the results of the form were somewhat different from data that were shown by male patients. Women with moderate acne had average value 7 points, the median – 7.5 mode – 8; among women who had severe acne course the average value was – 8, median – 9. Conclusions. As can be seen from the results of the questionnaire, respondents in all groups were shown a significant effect of disease on the psycho-emotional state of patients.

    Facial exercises are a noninvasive alternative to medical approaches to facial rejuvenation. Logopedists could be involved in providing these exercises. Little research has been conducted, however, on the effectiveness of exercises for facial rejuvenation. This study assessed the effectiveness of 4 exercises purportedly reducing wrinkles and sagging of the facial skin. A control group study was conducted with 18 participants, 9 of whom (the experimental group) underwent daily training for 7 weeks. Pictures taken before and after 7 weeks of 5 facial areas (forehead, nasolabial folds, area above the upper lip, jawline and area under the chin) were evaluated by a panel of laypersons. In addition, the participants of the experimental group evaluated their own pictures. Evaluation included the pairwise presentation of pictures before and after 7 weeks and scoring of the same pictures by means of visual analogue scales in a random presentation. Only one significant difference was found between the control and experimental group. In the experimental group, the picture after therapy of the upper lip was more frequently chosen to be the younger-looking one by the panel. It cannot be concluded that facial exercises are effective. More systematic research is needed. © 2013 S. Karger AG, Basel.

    2009-02-01

    Laser therapy with a 1,450 nm diode laser is a clinically effective treatment for acne vulgaris, although the mechanism of action is unknown. To investigate this, we conducted a small, prospective, controlled clinical trial to assess this laser's effects on the facial sebum excretion rate (SER). Fourteen healthy volunteers without active acne were enrolled in this study and received three laser treatments on test areas of the nose and forehead. Nine subjects completed the treatment regimen and were available for follow-up. SER was measured with Sebumeter prior to the first treatment, and at 1 week and 1 month after the third treatment. Photographs were taken and subjective assessment of skin oiliness and pore size determined by questionnaires at 1 month follow-up. No significant reduction in SER was observed comparing treated with control on all treatment sites (P>0.05) on the nose. Reduction in the absolute SER was observed for both test and control sites on the forehead, reaching significance on the treatment site (P = 0.04) and marginal significance on the control site (P = 0.08). While our study was designed to detect only large changes in SER, we conclude that three 1,450 nm laser treatment sessions did not cause marked changes in SER compared to the control (i.e., >44%). Thus, major destruction of sebaceous glands as a result of this treatment is unlikely. However, reduced sebum production was observed on both treatment and control sides at 1 month. Therefore alternative mechanisms should also be considered to explain the clinical efficacy of this treatment for acne vulgaris. (c) 2009 Wiley-Liss, Inc.

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

    Progressive macular hypomelanosis (PMH) is a skin disorder that is characterized by hypopigmented macules and usually seen in young adults. The skin microbiota, in particular the bacterium Propionibacterium acnes, is suggested to play a role. Here, we compared the P. acnes population of 24 PMH...... lesions from eight patients with corresponding nonlesional skin of the patients and matching control samples from eight healthy individuals using an unbiased, culture-independent next-generation sequencing approach. We also compared the P. acnes population before and after treatment with a combination...... of lymecycline and benzoylperoxide. We found an association of one subtype of P. acnes, type III, with PMH. This type was predominant in all PMH lesions (73.9% of reads in average) but only detected as a minor proportion in matching control samples of healthy individuals (14.2% of reads in average).

    The purpose of this literature review is to evaluate the use of metformin as an adjunct therapy in the treatment of moderate-to-severe acne in those not diagnosed with polycystic ovary syndrome (PCOS) or androgen excess. The authors conducted independent literature searches. Results were limited to clinical trials and randomized controlled trials. Studies with participants diagnosed with moderateto-severe acne vulgaris taking metformin versus placebo or other active treatment were included;studies with participants diagnosed with PCOS or androgen excess were excluded. The authors found three studies consistent with the search guidelines that evaluated the effects of metformin as adjunct therapy in moderate to severe acne vulgaris. In eachstudy, metformin was an effective adjunct therapy in the treatment of moderate-to-severe acne vulgaris.

    Cutibacterium (Propionibacterium) acnes , a gram-positive bacillus with low pathogenicity, is an uncommon but known cause of prosthetic joint infections, particularly related to shoulder surgery. C. acnes , however, is an extremely rare pathogen in the nonoperated knee joint. This report details an uncommon case of C. acnes septic knee arthritis after multiple intra-articular steroid injections in a 56-year-old male patient. After an indolent presentation and late diagnosis, the patient underwent surgical debridement with IV antibiotic management. This case illustrates that intra-articular corticosteroid injections for the management of osteoarthritis are not without risk. Literature supporting their use remains limited and clinicians should use proficient clinical judgment for appropriate patient selection for these injections. Vigilance following injections or aspirations of the knee should be maintained to identify the indolent clinical presentation of C. acnes septic arthritis. PMID:28825032

    Abuse of anabolic-androgenic steroids (AAS) by members of fitness centers and others in Germany has reached alarming dimensions. The health care system provides the illegal AAS to 48.1 % of abusers. Physicians are involved in illegal prescription of AAS and monitoring of 32.1 % of AAS abusers. Besides health-threatening cardiovascular, hepatotoxic and psychiatric long-term side effects of AAS, acne occurs in about 50 % of AAS abusers and is an important clinical indicator of AAS abuse, especially in young men 18-26 years of age. Both acne conglobata and acne fulminans can be induced by AAS abuse. The dermatologist should recognize bodybuilding acne, address the AAS abuse, and warn the patient about other potential hazards.

    Background. Facial blushing is one of the most peculiar of human expressions. The pathophysiology is unclear, and the prevalence is unknown. Thoracoscopic sympathectomy may cure the symptom and is increasingly used in patients with isolated facial blushing. The evidence base for the optimal level...... of targeting the sympathetic chain is limited to retrospective case studies. We present a randomized clinical trial. Methods. 100 patients were randomized (web-based, single-blinded) to rib-oriented (R2 or R2-R3) sympathicotomy for isolated facial blushing at two university hospitals during a 6-year period...... between R2 and R2-R3 sympathicotomy for isolated facial blushing. Both were effective, and QOL increased significantly. Despite very frequent side effects, the vast majority of patients were satisfied. Surprisingly, many patients experienced mild recurrent symptoms within the first year; this should...

    Research into emotions has increased in recent decades, especially on the subject of recognition of emotions. However, studies of the facial expressions of emotion were compromised by technical problems with visible video analysis and electromyography in experimental settings. These have only recently been overcome. There have been new developments in the field of automated computerized facial recognition; allowing real-time identification of facial expression in social environments. This review addresses three approaches to measuring facial expression of emotion and describes their specific contributions to understanding emotion in the healthy population and in persons with mental illness. Despite recent progress, studies on human emotions have been hindered by the lack of consensus on an emotion theory suited to examining the dynamic aspects of emotion and its expression. Studying expression of emotion in patients with mental health conditions for diagnostic and therapeutic purposes will profit from theoretical and methodological progress.

    The facial nerve is responsible for the motor innervation of the face. It has a visceral motor function (lacrimal, submandibular, sublingual glands and secretion of the nose); it conveys a great part of the taste fibers, participates to the general sensory of the auricle (skin of the concha) and the wall of the external auditory meatus. The facial mimic, production of tears, nasal flow and salivation all depend on the facial nerve. In order to image the facial nerve it is mandatory to be knowledgeable about its normal anatomy including the course of its efferent and afferent fibers and about relevant technical considerations regarding CT and MR to be able to achieve high-resolution images of the nerve.

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

    Facial injuries in children always present a challenge in respect of their diagnosis and management. Since these children are of a growing age every care should be taken so that later the overall growth pattern of the facial skeleton in these children is not jeopardized. To access the most feasible method for the management of facial injuries in children without hampering the facial growth. Sixty child patients with facial trauma were selected randomly for this study. On the basis of examination and investigations a suitable management approach involving rest and observation, open or closed reduction and immobilization, trans-osseous (TO) wiring, mini bone plate fixation, splinting and replantation, elevation and fixation of zygoma, etc. were carried out. In our study fall was the predominant cause for most of the facial injuries in children. There was a 1.09% incidence of facial injuries in children up to 16 years of age amongst the total patients. The age-wise distribution of the fracture amongst groups (I, II and III) was found to be 26.67%, 51.67% and 21.67% respectively. Male to female patient ratio was 3:1. The majority of the cases of facial injuries were seen in Group II patients (6-11 years) i.e. 51.67%. The mandibular fracture was found to be the most common fracture (0.60%) followed by dentoalveolar (0.27%), mandibular + midface (0.07) and midface (0.02%) fractures. Most of the mandibular fractures were found in the parasymphysis region. Simple fracture seems to be commonest in the mandible. Most of the mandibular and midface fractures in children were amenable to conservative therapies except a few which required surgical intervention.

    Propionibacterium acnes has been linked to chronic infections in shoulder surgery. Whether the bacterium is a contaminant or commensal of the deep tissue is unclear. We aimed to assess P. acnes in intraoperative samples of different tissue layers in patients undergoing first-time shoulder surgery. In 118 consecutive patients (mean age, 59.2 years; 75 men, 43 women), intraoperative samples were correlated to preoperative subacromial injection, the type of surgical approach, and gender. One skin, one superficial, one deep tissue, and one test sample were cultured for each patient. The cultures were positive for P. acnes in 36.4% (n = 43) of cases. Subacromial injection was not associated with bacterial growth rates (P = .88 for P. acnes; P = .20 for bacteria other than P. acnes; P = .85 for the anterolateral approach; P = .92 for the deltopectoral approach; P = .56 for men; P = .51 for women). Skin samples were positive for P. acnes in 8.5% (n = 10), superficial samples were positive in 7.6% (n = 9), deep samples were positive in 13.6% (n = 16), and both samples (superficial and deep) were positive in 15.3% (n = 18) of cases (P shoulder surgery. Preoperative subacromial injection was not associated with bacterial growth. P. acnes was observed more frequently in the deep tissues than in the superficial tissues. The relative risk for obtaining a positive P. acnes culture was 2-fold greater for the anterolateral approach than for the deltopectoral approach, and the risk was 2.5-fold greater for men.

    Acne vulgaris is a chronic inflammatory disease, and its treatment is challenging due to the multifactorial etiology and emergence of antibiotic-resistant Propionibacterium acnes strains. This study was focused to reduce antibiotics usage and find an alternate therapeutic source for treating acne. Lipid extracts of six Chlorella species were tested for inhibition of lipase, reactive oxygen species (ROS) production, cytokine production using P. acnes (Microbial Type Culture Collection 1951). Lipase inhibitory assay was determined by dimercaprol Tributyrate - 5, 5'- dithiobis 2-nitrobenzoic acid method and ROS production assay was performed using nitro-blue tetrazolium test. The anti-inflammatory activity of algal lipid extracts was determined by in vitro screening method based on inhibition of pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-α) produced by human peripheral blood mononuclear cells. Minimum inhibitory concentration (MIC) values of lipid extracts were determined by microdilution method, and the fatty acid methyl esters (FAME) were analyzed by gas chromatography-mass spectroscopy. Chlorella ellipsoidea has the highest lipase inhibitory activity with 61.73% inhibition, followed by Chlorella vulgaris (60.31%) and Chlorella protothecoides (58.9%). Lipid extracts from C. protothecoides and C. ellipsoidea has significantly reduced the ROS production by 61.27% and 58.34% respectively. Inhibition of pro-inflammatory cytokines TNF-α showed the inhibition ranging from 58.39% to 78.67%. C. vulgaris has exhibited the MICvalue of 10 μg/ml followed by C. ellipsoidea, C. protothecoides and Chlorella pyrenoidosa (20 μg/ml). FAME analysis detected 19 fatty acids of which 5 were saturated fatty acids, and 14 were unsaturated fatty acids ranging from C14 to C24. The results suggest that lipid extracts of Chlorella species has significant inhibitory activity on P. acnes by inhibiting lipase activity. Further, anti-inflammatory reaction caused by the
