ABSTRACT The present study investigated how patients with acne vulgaris cope with their disease. By means of questionnaires, relations and interactions between acne and psyche were evaluated. In addition to the evaluation of a specific questionnaire for patients with chronic skin disorders (CSD), assessing psychosocial impairment by the disease, depression and social anxiety were investigated in patients with acne. The study included 50 patients with acne. The CSD showed significant correlations with Beck's depression inventory, the interaction-anxiety questionnaire and the health locus of control scale. The CSD revealed significant differences compared to a control group of 33 patients with healthy skin. Furthermore the patients' attitudes towards triggering factors and disease-related limitations in everyday life are presented. The results of the study demonstrate that patients with acne suffer from emotional distress and psychosocial problems caused by their disease; however, impairment is not correlated with the objective severity of acne.

    ABSTRACT: Acne is the most common skin disorder. In the majority of cases, acne is a disease that changes its skin distribution and severity over time; moreover, it can be a physically (scar development) and psychologically damaging condition that lasts for years. According to its clinical characteristics, it can be defined as a chronic disease according to the World Health Organization criteria. Acne is also a cardinal component of many systemic diseases or syndromes, such as congenital adrenal hyperplasia, seborrhea-acne-hirsutism-androgenetic alopecia syndrome, polycystic ovarian syndrome, hyperandrogenism-insulin resistance-acanthosis nigricans syndrome, Apert syndrome, synovitis-acne-pustulosis-hyperostosis-osteitis syndrome, and pyogenic arthritis-pyoderma gangrenosum-acne syndrome. Recent studies on the Ache hunter gatherers of Paraguay detected the lack of acne in association with markedly lower rates of obesity, diabetes mellitus, hyperlipidemia, and cardiovascular diseases, a finding that indicates either a nutritional or a genetic background of this impressive concomitance.

    ABSTRACT: BACKGROUND Measuring the quality of life measure of patients with dermatologic diseases is an important concern. The instruments to evaluate it are commonly originally written in English and need to be translated and validated to be used in different cultures. OBJECTIVE The purpose of this paper is to translate and validate the Skindex-29 questionnaire to Brazilian Portuguese to be used in our country as a quality of life assessment instrument in dermatologic patients. METHODS The first step was the translation from English to Brazilian Portuguese and the back-translation by two native speakers. The translated version was then used for the second step, when three questionnaires were applied to 75 patients (43 of whom were classified as lightly affected and 32 as heavily affected by their dermatologic conditions): an identification questionnaire, the translated version of Skindex-29, and the Brazilian Portuguese version of Dermatologic Life Quality Index (DLQI). Additionally, the generic questionnaire Short Form 36 (SF-36) was applied to 41 of these patients. The last step to evaluate reproducibility was repeating the Skindex-29 questionnaire by the same researcher one week later in 44 patients. RESULTS Reliability was observed in global Skindex-29 scale (α=0.934), and its domains emotions (α=0.926), symptoms (α=0,702), and psycosocial functioning (α=0.860). The reproducibility showed high intraclass correlations. High intra class correlations was observed, thus validating reliability. CONCLUSIONS The Skindex-29 quality of life questionnaire was properly translated and validated to Brazilian Portuguese.

    ABSTRACT: Background and objectives Major depressive disorder is one of the most common psychiatric disorders in patients with acne. The objective was to assess the association between acne and depression. Method We performed a case-control study in a private outpatient clinic in Santiago, Chile. The case group was composed of adult patients attending our center with a clinical diagnosis of acne, established by an experienced dermatologist. The control group consisted of adult patients without acne who were related to subjects in the case group. Cases and controls were matched by sex, age and socioeconomic status. To measure depressive disorder, the Compound International Diagnostic Interview (CIDI) was applied to both groups. All the numerical variables were compared with Student’s t-test and categorical variables were compared with the χ2 test and odds ratios. Results Sixty patients were included (30 in each group): 21 females and nine males. All patients completed the questionnaire. No significant differences were found between the two groups in any of the demographic variables analyzed. In the case group, nine patients (30%) met the diagnostic criteria for major depressive disorder, whereas only two patients (6.6%) in the control group met these criteria (OR = 6; 95% confidence interval, 1.03-45.22; p = 0.02). Conclusions We found a statistically significant association between major depressive disorder and acne. The risk of depression was approximately 6 times greater in patients with this disorder.
