Avaliação da segurança e eficácia de novo preenchedor à base de ácido hialurônico no tratamento dos sulcos nasolabiais e contorno dos lábios

Introduction: The use of dermal filling techniques for soft tissue augmentation has greatly increased in recent years. Hyaluronic acid is one of the most used temporary dermal fillers in the treatment of facial wrinkles, furrows, and folds due to its effectiveness and safety. Objective: To evaluate the efficacy and safety of Perfectha®, a new hyaluronic acid filler, for nasolabial folds and lip correction. Methods: Open, multicenter study comprising 87 women. Efficacy was evaluated by the Global Aesthetic Improvement Scale and the Wrinkle Severity Rating Scale. Safety was evaluated through observation and the reporting of side effects. Results: One week after the injection of the filler, improvement in nasolabial folds and lips was observed in 86% and 89% of the women, respectively. Mild or moderate transient inflammatory reaction and ecchymoses occurred in 15% and 9% of patients, respectively, mainly in nasolabial folds. Two patients presented labial herpes simplex after treatment of the lips. The good results were maintained in 76% and 57% of women for nasolabial folds and in 72% and 45% of women for lips after 3 and 6 months, respectively. Conclusion: Perfectha® was effective and safe for these indications.

Uso do AHP na avaliação do desempenho do sistema de gestão da qualidade, meio ambiente e segurança e saúde ocupacional integrados

The paper analyses the application of the AHP method together with the attach A of ISO 9004:2000 in order to evaluate the performance of two industrial organizations, both possessing quality management systems with ISO 9001:2000 certifications, based on the specific requirements of quality, environment, occupational health and management systems. The evaluated organizations were a government-owned company from the science and technology sector that works in the nuclear area, and a private company that works in the automotive and railroad area. The open software Web-Hipre version 1.22 from Helsinki University of Technology, Finland, was used. The results demonstrated that the AHP method together with the attach A of ISO 9004:2000 is adequate to evaluate organizational performances. Both organizations presented similar performance levels.

Estudo da segurança de cosméticos: Presente e futuro

Cosmetics have been used since ancient times and, recently, their consumption has increased greatly in many countries, including brazil, which is the third largest consumer market in the world. Thus, concern for the safety and efficacy of these products should be heightened, even though these products are rarely related to adverse reactions that damage the health. Brazilian law requires manufacturers to subject their products to safety testing, to assess the possible reactions that could be caused by them (irritation, sensitization, systemic effects). To this end, in general, animals have been used as the experimental model, but this practice is being increasingly controlled, so that the scientific community is looking for alternative tests that do not require experimental in vivo models. Thus, this review aims to describe the main biological assays used to assess the safety of cosmetics, as well as in vitro assays that can replace them.

Can savannas become forests? A coupled analysis of nutrient stocks and fire thresholds in central Brazil

Aims: The effects of fire ensure that large areas of the seasonal tropics are maintained as savannas. The advance of forests into these areas depends on shifts in species composition and the presence of sufficient nutrients. Predicting such transitions, however, is difficult due to a poor understanding of the nutrient stocks required for different combinations of species to resist and suppress fires. Methods: We compare the amounts of nutrients required by congeneric savanna and forest trees to reach two thresholds of establishment and maintenance: that of fire resistance, after which individual trees are large enough to survive fires, and that of fire suppression, after which the collective tree canopy is dense enough to minimize understory growth, thereby arresting the spread of fire. We further calculate the arboreal and soil nutrient stocks of savannas, to determine if these are sufficient to support the expansion of forests following initial establishment. Results: Forest species require a larger nutrient supply to resist fires than savanna species, which are better able to reach a fire-resistant size under nutrient limitation. However, forest species require a lower nutrient supply to attain closed canopies and suppress fires; therefore, the ingression of forest trees into savannas facilitates the transition to forest. Savannas have sufficient N, K, and Mg, but require additional P and Ca to build high-biomass forests and allow full forest expansion following establishment. Conclusions: Tradeoffs between nutrient requirements and adaptations to fire reinforce savanna and forest as alternate stable states, explaining the long-term persistence of vegetation mosaics in the seasonal tropics. Low-fertility limits the advance of forests into savannas, but the ingression of forest species favors the formation of non-flammable states, increasing fertility and promoting forest expansion. © 2013 Springer Science+Business Media Dordrecht.
