Brazilian Consensus on Photoprotection

Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of non-melanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection.

Cybertutor: um objeto de ensino na Dermatologia

It was developed a teaching tool in Dermatology for undergraduate medical students, using an interactive website, the Cybertutor. Clinical cases, lectures and updated bibliography were selected. Photographies of dermatological lesions were taken from ambulatory patients. The topics of the lectures were based on the current curriculum of the Federal University of Rio Grande do Sul. The Cybertutor is a dynamic and modern teaching tool, allowing constant innovation.

Skin manifestations of obesity: a comparative study

Background  Obesity is one of the world’s biggest health problems nowadays. Little research has been done on the skin diseases that affect obese patients.

Effects of age (neonates and elderly) on skin barrier function

Skin, together with its appendages, forms an organ with several defensive roles; among them it acts as a barrier, which is one of its very important protective functions. There has been increased interest in studying the effects of age on these functions. There are different intensities and timing involved in this process and also differences between men and women, all relating to skin structure. We review the current knowledge of the skin as a barrier in neonates and in the elderly in an attempt to explain the changes that occur with aging.

Translation into Brazilian portuguese and validation of the psoriasis family index

Psoriasis Family Index is a quality of life instrument for family members of patients with psoriasis developed in English. The aims of this study were to translate the Psoriasis Family Index into Brazilian Portuguese, culturally adapt it and verify its reliability and validity. The study followed these two steps: 1) Translation, linguistic and cultural adaptation, 2) Validation. The translated Psoriasis Family Index showed high internal consistency and high test-retest reliability, confirming its reproducibility. The Portuguese version of the Psoriasis Family Index was validated for our population and can be recommended as a reliable instrument to assess the QoL of family members and partners of patients with psoriasis.

Quality of Life Impairment in Children and Adults with Vitiligo: A Cross-Sectional Study Based on Dermatology-Specific and Disease-Specific Quality of Life Instruments.

Background: Vitiligo can negatively affect a patients quality of life (QoL). A specific questionnaire has been developed and validated in the English language: the vitiligo-specific quality-of-life instrument (VitiQoL). The instrument was translated, culturally adapted and validated into Brazilian Portuguese (VitiQoL-PB). Objective: The aim of this study was to assess the QoL in adult patients through the VitiQoL and Dermatology Life Quality Index (DLQI) and in pediatric patients through the Childrens Dermatology Life Quality Index (CDLQI) in a sample of patients with vitiligo. Methods: Subjects were selected from a dermatological outpatient clinic and from a private practice in Porto Alegre. The QoL of pediatric patients was evaluated using the CDLQI questionnaire. In adult patients we used the VitiQoL-PB and the DLQI. Results: A strong correlation between the scores of the total VitiQoL and DLQI was observed (r = 0.81; p < 0.001). The factor that most contributed to the final score of VitiQoL was stigma. In our sample, women had higher scores than men (p < 0.05). Psychiatric problems were associated with lower QoL. In the pediatric population, the median score of the CDLQI was 3 (interquartile range 1.3-7.3). There was a statistically significant correlation between the childs age and the CDLQI score (rs = 0.41, p = 0.044). Conclusion: This study confirms that the VitiQoL is easy to administer and adds important information about the impact of vitiligo on a South American population. Stigmatization is very present in the disease. There are groups of patients that are more vulnerable, like women, patients with psychiatric diseases and adolescents.

EXPERIMENTAL DERMATOLOGICAL SURGERY: AN ANIMAL MODEL FOR DEVELOPING SKILLS WITH DERMAL FILLERS

The importance of laboratory experiments in the formation of physicians is well recognized since they facilitate scientific development and enhance technical skills. Dermal filling procedures are performed for the correction of wrinkles, rhytids, scars, and lipodystrophy. Till date, experimental models for the training of dermal filling techniques have not been studied. To demonstrate an experimental laboratory model for the training of dermal filling techniques in an animal model. The heads of pigs were used for this purpose, together with Carbopol gel at different densities, which was used to simulate the fillers available in the market. Needles and specific cannulas were used to apply the fillers into the creases and other areas of the pig skin. The pig head appears to be a suitable model for this training. Carbopol gel is a good choice for simulating fillers. This model of laboratory experiment requires a minimum of infrastructure; it is a low-cost alternative and facilitates practical training in the application of dermal fillers.

Association between clinical characteristics, quality of life, and sleep quality in patients with periorbital hyperchromia

Periorbital hyperchromia (POH) is a multifactorial condition, precipitated or aggravated by sleep disorders, which negatively affects quality of life (QoL). The aim of this study was to evaluate the impact of POH on QoL, sleep quality, and dissatisfaction of affected patients.

Vitiligo-specific instrument on quality of life - Brazilian Portuguese version.

Mr. Editor, As the authors of the article “Translation, cross-cultural adaptation and validation of the vitiligo-specific health-related quality of life instrument (VitiQoL) into Brazilian Portuguese”, we would like to publish the translated version of VitiQol in Portuguese (Chart 1 and 2).1 This instrument has only been published in English, and we have been contacted by other health professionals to provide a validated version in Portuguese.
