Abstract
BACKGROUND Excessive androgenesis in the skin promotes sebaceous hyperproduction which is the onset of acne vulgaris pathogenesis. Free fatty acids and lipid accumulation in the glandular infundibulum culminates in microbiota imbalance, triggering inflammatory response and follicular hyperkeratinization. AIMS The purpose of this work was to present an alternative cosmetic treatment for acne skin care, focusing on the prevention of sebaceous gland dysregulation. METHODS Insulin-stimulated human sebocytes were treated with noncytotoxic concentrations of a DTRW cosmetic formulation. After 6 days of incubation, cell lysates were collected for testosterone, 5α-reductase, and dyhidrotestosterone (DHT) quantitation. In parallel, cells were stained with Oil Red O to measure sebum production. RESULTS Human sebocytes were incubated with insulin to mimic a seborrheic microenvironment with overproduction of intracellular lipids and fatty acids. Concomitant incubation of cell cultures with DRTW was able to promote a 52.97% reduction in intracellular lipid content. The anti-androgenic properties of DRTW had been proved by the reductions of testosterone (↓59.90%), 5α reductase (↓59.34%), and DHT (↓55.98%) levels in sebocyte cultures also stimulated with insulin. CONCLUSION The results indicate a promising action of DRTW cosmetic formulation in preventing the development of acne lesions by mechanisms involving the modulation of cutaneous androgenesis and consequently the control of sebum overproduction, considered one of the leading causes of acne.

Abstract
Acne vulgaris treatments usually cause sensitivity, teratogenicity and bacterial resistance. Investigations of other therapeutic techniques, such as phototherapy, are highly relevant. Thus, we compared the effectiveness of two Acne vulgaris treatments in adolescents: peeling with salicylic acid (SA) and phototherapy. Teens were randomly divided into: group I, treatment with SA peels (10%) and group II, treatment with phototherapy (blue LED and red laser lights). Photographs were taken before and after ten sessions of each treatment, carried out weekly, and compared. To compare the differences between the treatments, the Student t-test was used. P values < 0.05 were considered significant. Both techniques are effective therapies for the treatment of acne in teenagers since the number of comedones, papules and pustules decreased significantly at the end of the session. However, when the two treatments were compared, phototherapy showed a significant difference in reducing the number of pustules. The combined use of red and blue lights due to their anti-inflammatory and wound-healing properties is a more efficient alternative for treating Acne vulgaris in relation to SA and proves more reliable and without side effects, improving the adolescents' skin health.

Abstract
BACKGROUND Acne vulgaris has high prevalence, disturbing quality of life during
adolescence. OBJECTIVES To measure dissastifaction and acne in 18-year-old male individuals and its
associated factors. METHODS A questionnaire was applied by trained interviewers to all boys during
selection for the military service. Dissatisfaction and acne was evaluated
using a self-administered face scale. Facial, prestrernal and dorsal acne
were evaluated separately. RESULTS A total of 2,200 adolescents, aged 18 years, were interviewed. Among these,
1,678 had acne on the face and 974 (54.05%) showed some degree of
dissatisfaction. Regarding the impact of acne located on the chest, 326 out
of 686 adolescents (47.52%) reported dissatisfaction. For acne located on
the back, 568 out of 1,103 affected individuals (51.50%) showed
dissatisfaction. Facial / dorsal acne and dissatisfaction were statistically
associated with lower income, lower education levels and with non-whites.
Presternal acne and dissatisfaction were statistically asssociated with
lower income and lower education levels. CONCLUSION This population-based study found a high prevalence of acne on the face,
back and chest, with high rates of dissatisfaction.

Abstract
BACKGROUND 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 OBJECTIVE To determine if the presence of keratosis pilaris is associated with lower
prevalence and severity of acne. METHODS 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. RESULTS 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]; p<0.01). Acne was present in 66% of
subjects, and was related to family history of acne (OR=5.75 [2.47 to 13.37];
p<0.01). In bivariate and multivariate analysis, the group with keratosis
pilaris had a less frequent history of acne (OR=0.32 [0.14 to 0.70];
p<0.01). CONCLUSION The presence of moderate to severe keratosis pilaris on the arms was associated
with lower prevalence of acne vulgaris and lower severity of facial lesions in
adolescents and young adults.

Abstract
BACKGROUND many studies about the psychosocial impact of acne have been reported in international medical literature describing quality of life as a relevant clinical outcome. It is well known that the patient's perception about the disease may be different from the physician's evaluation. Therefore, it is important to use validated instruments that turn the patient's subjective opinion into objective information. OBJECTIVES to translate into Brazilian-Portuguese language and to culturally adapt a quality of life questionnaire, the Acne-Specific Quality of Life Questionnaire (Acne-QoL), as well as to evaluate its reliability and validity. METHODS measurement properties were assessed: 1) validity: comparison between severity and Acne-QoL domain scores, correlations between acne duration and Acne-QoL domain scores, and correlation between Acne-QoL domain scores and SF-36 components; 2) internal consistency: Cronbach's α coefficient; 3) test-retest reproducibility: intraclass correlation coefficient and Wilcoxon test. RESULTS Eighty subjects with a mean age of 20.5 ± 4.8 years presenting mild (33.8%), moderate (36.2%) and severe (30%) facial acne were enrolled. Acne-QoL domain scores were similar among the different acne severity groups except for role-social domain. Subjects with shorter acne duration presented significant higher scores. Acne-QoL domains showed significant correlations, both between themselves and with SF-36 role-social and mental health components. Internal consistency (0.925-0.952) and test-retest reproducibility were considered acceptable (0.768-0.836). CONCLUSIONS the Brazilian-Portuguese version of the Acne-QoL is a reliable and valid satisfactory outcome measure to be used in facial acne studies.

Abstract
Background. Acne is a dermatosis that involves an altered sebum pattern. Objectives. (1) To evaluate if a treatment based on antibiotics (lymecycline) can alter fatty acids contents of the sebum of patients with acne; (2) to evaluate if oral supplementation of fatty acids can interfere with fatty acids contents of the sebum of patients with acne; (3) to evaluate if there is any interaction in fatty acids contents of the sebum of patients with acne when they use both antibiotics and oral supplementation of fatty acids. Methods. Forty-five male volunteers with inflammatory acne vulgaris were treated with 300 mg of lymecycline per day, with 540 mg of γ-linolenic acid, 1,200 mg of linoleic acid, and 510 mg of oleic acid per day, or with both regimens for 90 days. Every 30 days, a sample of sebum from the forehead was collected for fatty acids' chromatographic analysis. Results. Twelve fatty acids studied exhibited some kind of pattern changes during the study: C12:0, C14:0, C15:0, C16:1, C18:0, C18:1n9c+C18:1n9t, C18:2n6t, C18:3n6, C18:3n3, C20:1, C22:0, and C24:0. Conclusions. The daily administration of lymecycline and/or specific fatty acids may slightly influence some fatty acids levels present in the sebum of patients with inflammatory acne vulgaris.

Abstract
BACKGROUND Currently, 13-cis-retinoic acid (13-cis-RA) is the most effective therapy for acne. Isotretinoin, a first-generation synthetic 13-cis-RA compound, is associated with numerous adverse effects. To investigate the cardiac effects of 13-cis-RA, acne patients receiving 13-cis-RA were studied. METHODS Twenty male patients with acne were enrolled in the study. Patients were treated with a dose of 0.5 mg/kg/d of isotretinoin. All participants were assessed prior to treatment and after 10 weeks of therapy with Doppler-echocardiogram. RESULTS Patients showed reductions in right atrium vertical diameter, left atrium longitudinal diameter, left atrium volume and left ventricular diastolic diameter over the course of treatment. Significant increases in interventricular septum diastolic thickness, posterior wall diastolic thickness, relative wall relative thickness and left ventricle (LV) mass were observed. The LV mass index showed an increase in ventricular mass and a decrease in the cavity size. Examining LV systolic function, a decrease was observed for the cardiac index. CONCLUSION In this study, 10 weeks of 13-cis-RA therapy at a dose of 0.5 mg/kg/d was found to promote concentric-type heart remodeling due to the occurrence of two associated events: heart hypertrophy and hypovolemia.

Abstract
Nos últimos 50 anos, foram publicados inúmeros estudos com a finalidade de comprovar se a dieta está relacionada à etiologia da acne. Embora existam estudos antigos, que são bem difundidos entre os dermatologistas e negam a associação entre acne e dieta, seu delineamento científico é pobre. Recentemente, novos artigos demonstraram evidências contrárias às publicações anteriores. Sendo assim, os autores realizaram esta revisão bibliográfica com o intuito de averiguar se a dieta influencia direta ou indiretamente um ou mais dos quatro pilares etiopatogênicos fundamentais da acne: (1) hiperproliferação dos queratinócitos basais, (2) aumento da produção sebácea, (3) colonização pelo Propionibacterium acnes e (4) inflamação.

Abstract
BACKGROUND Acne is a frequent skin disease that occurs in both sexes and all age-groups. Women present several clinical disease patterns; moreover, persistence after adolescence is common. OBJECTIVE To analyze clinical and epidemiological characteristics associated with different age-groups affected by acne in women. METHODS Cross-sectional study involving female patients diagnosed with acne, at a general dermatology outpatient clinic. Variables related to disease and patients were assessed through a standardized questionnaire. RESULTS One hundred and three women were assessed. The average age of patients at the time of the consultation was 21.7 +/- 7.3 years. Two groups were defined (cut-off age of 21 years), with means of 15.8 +/- 2.3 and 28.0 +/- 5.1 years. There was correlation between disease duration and current age (R=0.7). There were group differences among frequencies of covariables: combined oral contraceptive (OR=48.1), lesions located on upper chest (OR=11.6), lesions on upper dorsum (OR=0.2), predominance on upper half of face (OR=0.1) and age at disease onset (OR=1.8). Among adult women, 80% reported acne onset before 20 years of age. CONCLUSION Chronologic and topographic patterns of female acne in different age-groups were defined, reinforcing the importance of an individualized diagnostic and therapeutic approach.
