ABSTRACT

ABSTRACT Objective: To describe the upper and lower blepharoplasty technique associated with canthopexy with double pre septal orbicularis muscle elevation with a single suture in order to evaluate the efficacy of the technique. Methods: This is a retrospective study in which the medical records of 5,882 patients who underwent this technique between January 1999 and July 2015 were evaluated. The frequency and main causes of clinical complications and surgical reoperation were analyzed. Results: The incidence of complications found was 12.7% (n=750), being 0.8% (n=47) due to persistent chemosis, 3% (n=176) due to poor lower eyelid positioning, 4.17% (n=245) due to mild eyelid retraction and 4.8% (n=282) because of mild to moderate chemosis. Conclusion: The technique appears to be effective as it is simple and practical, and capable of resulting in positive functional and aesthetic outcomes with low rates of complications.

ABSTRACT

RESUMEN El envejecimiento es un proceso complejo que trae consigo cambios celulares, histológicos y cutáneos. Estos últimos son una de sus manifestaciones más evidentes. El plasma rico en plaquetas es una fuente fiable de obtención de células para regenerar tejidos; por su fácil disponibilidad es un material inocuo. La bioestimulación con el mismo, por su parte, es un conjunto de procedimientos para activar las funciones anabólicas de los fibroblastos, producción de colágeno, elastina y ácido hialurónico. La tendencia al empleo de este en tratamientos antiedad es cada vez mayor. El objetivo de este trabajo fue realizar una actualización del tema, para exponer aspectos importantes sobre formas de aplicación, indicaciones, complicaciones y contraindicaciones. Existen varios métodos para la bioestimulación facial, tales como la realización de pápulas, napagge y retroinyección. Se han empleado en alopecia androgénica, areata, envejecimiento cutáneo, etc. Las complicaciones más observadas son dolor, eritema, ardor y sangrado local. Entre las contraindicaciones más comunes se observan el herpes simple recidivante, coagulopatías, tratamiento con anticoagulantes, colagenopatías y neoplasias (AU).


ABSTRACT Aging is a complex process that brings with it cellular, histological and cutaneous changes, the latter being one of its most obvious manifestations. Platelet-rich plasma is a reliable source of cells to regenerate tissues; due to its easy availability, it is a harmless material. Bio-stimulation with it is a set of procedures to activate the fibroblasts anabolic functions and the production of collagen, elastin and hyaluronic acid. The tendency to use it in anti-aging treatments increases faster and faster. The objective of this work was updating the topic to expose important aspects about application methods, indications, complications and contraindications. There are several methods of applying facial bio-stimulation such as performing papules, napagge, and retroinjection. It has been used in androgenic alopecia, alopecia areata, cutaneous ageing, etc. The most commonly found complications are pain, erythema, burning and local bleeding. The most common contraindications include recidivist herpes simplex, coagulopaties, anticoagulant treatment, collagen-related diseases and neoplasms (AU).

ABSTRACT

Abstract Aim: To evaluate efficacy and safety of Botulinum toxinA for improving esthetics in the facial complex and correlating them to the dosage and side effects through a systematic review. Methods: A literature search was performed using PubMed, Medline, Web of Sciences, and Scopus databases. Quality of studies was appraised through the GRADE system. This review follows the 'Preferred reporting items for systematic review and meta-analysis protocols' (PRISMA-P) 2015 statement. Efficacy was analyzed through improvement rate and effect sizes. Graphical comparison of efficacy and ocular adverse effects (adverse effects around the eye) at various anatomical locations was made by calculating the average improvement rate and adverse events. Results: Twenty-five studies were included in this systematic review after application of the inclusion criteria. Moderate to severe cases in glabellar, lateral canthal, and forehead regions showed higher improvement rates between 20U to 50U, with an effect lasting up to 120 days. Gender and age seemed to have a direct effect on efficacy. Headaches were the most common adverse effect, followed by injection site bruising; all adverse effects resolved within 3-4 days. Conclusions: Treatment with Botulinum toxinA to enhance esthetics of facial complex is efficient and safe at all recommended dosages. Presence of complexing proteins influenced the efficacy of BoNT-A. undesirable muscular adverse effects around the eyes were more predominant when treating the glabellar region. There was no correlation found between the BoNT-A dosage and side effects, however, an increase in dosage did not always lead to an increase in efficacy.


Resumo Objetivo: Avaliar a eficácia e segurança da toxina botulínica-A para melhorar a estética no complexo facial e correlacioná-la com a dosagem e os efeitos secundários através de uma revisão sistemática. Métodos: Foi realizada uma pesquisa bibliográfica utilizando bases de dados PubMed, Medline, Web of Sciences, e Scopus. A qualidade dos estudos foi avaliada através do sistema GRADE. Esta revisão segue a declaração "Preferred reporting items for systematic review and meta-analysis protocols" (PRISMA-P) 2015. A eficácia foi analisada através da taxa de melhoria e da dimensão dos efeitos.A comparação gráfica da eficácia e dos efeitos adversos oftalmológicos (efeitos adversos em torno do olho) em vários locais anatômicos foi feita através do cálculo da taxa média de melhoria e dos eventos adversos. Resultados: Vinte e cinco estudos foram incluídos nesta revisão sistemática após a aplicação dos critérios de inclusão. Casos moderados a graves em regiões glabelares, canais laterais e testa mostraram taxas de melhoria mais elevadas entre 20U a 50U, com um efeito que durou até 120 dias. O sexo e a idade mostraram ter efeito direto na eficácia. As dores de cabeça foram o efeito adverso mais comum, seguido de hematomas no local da injecção; todos os efeitos adversos foram resolvidos em 3-4 dias. Conclusões: O tratamento com toxina botulínica-A para melhorar a estética do complexo facial é eficiente e seguro em todas as dosagens recomendadas. A presença de proteínas complexas influenciou a eficácia do BoNT-A. Os efeitos adversos musculares indesejáveis à volta dos olhos foram mais predominantes no tratamento da região glabelar. Não foi encontrada qualquer correlação entre a dosagem de BoNT-A e os efeitos secundários, contudo, um aumento da dosagem nem sempre levou a um aumento da eficácia.

ABSTRACT

ABSTRACT Purpose To evaluate the effect of fractional carbon dioxide (CO2) laser treatment using lower power associated with pulse stacking within collagen fibers, using second harmonic generation microscopy and computerized image analysis. Methods Twenty male Wistar rats aging eight weeks were used. Each treatment area received a single-pass CO2 fractional laser with different parameters. The 20 animals were divided into two groups and euthanized after 30 and 60 days. Second harmonic generation images were obtained and program ImageJ was utilized to evaluate the collagen organization within all areas. Collagen anisotropy, entropy and optical density were quantified. Results Increased anisotropy over time was observed in all four areas, but only reached statistical significance (p = 0.0305) when the mildest parameters were used (area four). Entropy decreased over time in all areas, but without significance(p = 0.1779) in area four. Density showed an overtime increase only in area four, but no statistical significance was reached (p = 0.6534). Conclusions When combined, the results obtained in this study regarding anisotropy, entropy and density tend to demonstrate that it is possible to achieve collagen remodeling with the use of lower power levels associated with stacked pulses.

ABSTRACT

Abstract The high consumption of antiaging cosmetics represents an outstanding opportunity for the development of new processes and attractive products in the cosmetic industry. Stability studies and sensory analyses are critical steps in the development process and production chain. Here we present a potential antiaging cosmetic product with innovative sensory characteristics. Caviar extract antioxidant properties were firstly evaluated by the DPPH method since it is an important mechanism against skin aging. Ca-alginate beads containing 2% of caviar extract and 0.2% of black pigment were prepared to obtain spheres similar to caviar. The beads were incorporated in a gel phase (hydroxyethylcellulose 2.5%) containing 3% of dimethylaminoethanol. Stability was evaluated in different storage conditions (sunlight exposure, 5 ± 2 °C, 37 ± 2 °C and r.t.) through the parameters: appearance, color and odor, pH (6-7), density (0.98-1.14 g.mL-1), centrifugation and average size. After approval by the Committee for Ethics in Research (n° 3.503.061), 30 volunteers tested the new formulation and answered a questionnaire. At 2%, caviar extract was able to scavenge 10.9% ± 0.58 of DPPH radical. Formulations showed good stability after 90 days, even considering the average size (7.47 ± 0.41 - 8.4 ± 0.65 mm2). 90% of the sensory test participants reported that they would buy the new product. Therefore, the new product developed demonstrates a promising potential as an attractive cosmetic product.

ABSTRACT

Si bien la cirugía del envejecimiento facial es uno de los procedimientos estéticos más frecuentes en la actualidad, tanto en varones como en mujeres, el lifting facial en los pacientes de sexo masculino requiere especial atención, debido a diversos factores en los cuales difi ere del mismo procedimiento en pacientes femeninas, como el uso de cabello corto, la presencia de barba y patillas, la calvicie, etc, así como el mayor celo de su intimidad y la reserva en los varones. Por lo tanto es de primordial importancia preservar la naturalidad. El propósito de este trabajo es presentar el diseño personal de las incisiones de abordaje para el lifting facial en pacientes de sexo masculino, y evaluar los resultados obtenidos.


Although surgery of the ageing face is one of the most frequent aesthetic procedure nowadays, both on male and female patients, face lift on the male patient requires special attention, due to diff erent aspects that make this procedure diff erent from female patients, such as short hair, the presence of beard and sideburns, baldness, etc., and greater privacy zeal in male patients. Thus naturalness is of paramount importance. The purpose of this article is to present our personal design in the approach of face lift on male patients, and evaluate the results achieved.

ABSTRACT

A qualidade e a função da pele reduzem-se drasticamente com a idade devido ao envelhecimento cronológico, ao fotoenvelhecimento, aos fatores ambientais e às deficiências hormonais. O declínio dos níveis de estrógeno na menopausa tem papel importante na atrofia cutânea, redução do colágeno, perda de elasticidade e deficiência da cicatrização de feridas. Pesquisas têm demonstrado os efeitos benéficos do estrogênio tópico, que teria ação mais localizada na pele sem efeitos colaterais sistêmicos. O objetivo deste estudo foi revisar a literatura pertinente ao assunto, demonstrando que o uso do estrogênio tópico pode ser uma alternativa segura e eficaz para o tratamento da pele de mulheres na perimenopausa.


Skin quality and function drastically reduces with age due to chronological aging, photoaging, environmental factors and hormonal deficiencies. Decreased menopausal estrogen levels play a role in cutaneous atrophy, collagen and water content, loss of elasticity, skin wrinkling and deficiency of wound healing. Much research has been done to elucidate the beneficial effects of topical estrogen, which would have a more localized action on the skin without systemic side effects. The objective of this study was to review the relevant literature, demonstrating that this may be a safe and effective alternative for the treatment of women's skin in perimenopause

ABSTRACT

The epidermis, the outermost layer of the skin, is the first barrier that comes into contact with the external environment. It plays an important role in resisting the invasion of harmful substances and microbial infections. The skin changes with age and external environmental factors. This study aimed to investigate epidermal stem cells during the process of aging. This study enrolled 9 volunteers with benign pigmented nevus for clinical dermatologic surgery. The phenotypes associated with skin aging changes such as skin wrinkles and elasticity of the unexposed/healthy parts near benign pigmented skin were measured, and epidermal stem cells from this region were isolated for transcriptome sequencing. The results showed that epidermal stem cells could be obtained by magnetic activated cell sorting (MACS) with high purity. Results of the transcriptome sequencing revealed that aquaporin (AQP)5 significantly decreased in the epidermal stem cells with age, and further functional experiments revealed that AQP5 could promote the proliferation and dedifferentiation of HaCaT, but did not influence cell apoptosis. In summary, AQP5 regulated the proliferation and differentiation of epidermal stem cells in skin aging, and it may play an important role in the balance of proliferation and differentiation. However, further studies are needed to determine the mechanism by which AQP5 regulates the proliferation and differentiation of epidermal skin cells in aging.

ABSTRACT

Ultraviolet radiation (UV) is related to the development of skin cancer and photoaging, also produces free radicals or reactive oxygen species (ROS) that cause premature aging. Therefore, sunscreens with extended UV protection capacity have been studied associated with antioxidant compounds. Different components can be incorporated with the purpose of improving, the photoprotection efficiency, as well as other cosmetic attributes, creating a multifunctional product. Among the compounds, there are some to be used from natural origin that are excellent, because it reduces the side effects and toxicity. Flavonoids are good examples of natural agents, because have demonstrated photoprotective antioxidant action in food and it is also promising for topical use. The aim of this work is to develop photoprotective formulations with quercetin, evaluating potential photoprotective and antioxidant of each formulation through tests already established and described in the literature, with emphasis on in vitro testing of potential photoprotective, antioxidant and security (het-cam); ex vivo antioxidant potential (tape-stripping). The results show us the photoprotective and antioxidant capacity of quercetin and the ideal concentration for this potential, thereby contributing to the synthesis of new molecules and development of new products, concerning stable, safe and effective exposure to solar UV radiation, preventing new incidences of skin cancer and reduction of photoaging


A radiação ultravioleta (UV) está relacionada ao desenvolvimento de câncer de pele e fotoenvelhecimento, também produz radicais livres ou espécies reativas de oxigênio (EROs) que causam o envelhecimento precoce. Portanto, protetores solares com capacidade de proteção UV amplo espectro foram estudados associados a compostos antioxidantes. Diferentes componentes podem ser incorporados com o objetivo de melhorar a eficiência da fotoproteção, assim como outros atributos cosméticos criando um produto multifuncional. Entre os compostos a serem utilizados, de origem natural são excelentes, pois reduzem os efeitos colaterais e a toxicidade. Os flavonóides são bons exemplos de agentes naturais, porque demonstraram ação antioxidante fotoprotetora nos alimentos e também são promissores para uso tópico. O objetivo deste trabalho é desenvolver formulações fotoprotetoras com quercetina, avaliando potenciais fotoprotetores e antioxidantes de cada formulação através de testes já estabelecidos e descritos na literatura com ênfase em ensaios in vitro de potenciais fotoprotetores, antioxidantes e de segurança (het-cam); potencial antioxidante ex vivo (tape-stripping). Os resultados nos mostram a capacidade fotoprotetora e antioxidante da quercetina e a concentração ideal para este potencial, contribuindo para a síntese de novas moléculas e desenvolvimento de novos produtos estáveis, seguros e eficazes em relação à exposição à radiação solar UV, prevenindo novas incidências de câncer de pele e redução do fotoenvelhecimento
