Preparation and evaluation of moisturizing hydrogel facial mask using alcohol-free microemulsion of olive oil compound as carrier / 中国药学杂志

OBJECTIVE: To investigate an efficient hydrating facial mask with olive oil (OL)/vitamin E succinate(VES) as the oil phase(O), and with hyaluronic acid, collagen, sodium alginate, arbutin, allantoin as the active ingredients, using a low concentration of surfactant(S) and alcohol-free microemulsion gel as the carrier. METHODS By investigating the effect of VES and co-surfactant (CoS) propylene glycol on microemulsion region, the microemulsion formulation was screened. The microemulsion characteristics of the facial mask were characterized by transmission electron microscopy and Malvern particle size determination. The moisturizing effect and transdermal absorption capacity of the facial mask were evaluated using a commercially available unifon mask as the reference substance. RESULTS Through the compounding of OL and VES, the microemulsion area of OL was increased, and microemulsion range was largest when the mass ratio of OL to VES was 6∶1.The use of the co-surfactant(propylene glycol) reduced the OL microemulsion area. The microemulsion with O/S mass ratio of 4/6 and water content of 85% was selected as the carrier, and the obtained droplet of the facial mask was round, the average particle size was (58.83±0.79) nm, and the PDI was (0.271±0.001), which were in line with the characteristics of microemulsion. Compared with commercial unifon mask, the moisturizing effect of the self-made microemulsion gel facial mask increased by 20.37%. The steady-state infiltration rates of 1% arbutin from the facial mask through the isolated cavy skin was 0.305 mg•cm-2•h-1, which was 4.29 times higher than that from the marketed unifon mask. This product was safe and stable, and meets the sensory and physicochemical indexes of the national light industry standard QB/T2872-2007. CONCLUSION The facial mask with OL/VES microemulsion gel as the carrier can improve the hydrating effect and the transdermal absorption of the active substance, it is expected to be promoted and developed.

The effect of noninvasive ventilation with the helmet compared with facial mask in patients with acute respiratory failure: a randomized controlled study / 中华急诊医学杂志

Objective To explore the effect of noninvasive ventilation (NIV) with helmet or facial mask on clinical efficacy, tolerability, and prognosis in patients with acute respiratory failure. Methods Fifty patients with acute respiratory failure according to the inclusion criteria were recruited from January 2018 to July 2018 in Emergency Intensive Care Unit of the First Affiliated Hospital of Zhengzhou University. Included patients were randomly allocated into the helmet group or facial mask group. Based on conventional drug therapy, pressure support mode was performed with the interface of the helmet or facial mask. Oxygenation index, arterial carbon dioxide partial pressure, and respiratory rates were measured before and after the treatment, and the data were compared and analyzed by the repeated measures ANOVA. Tolerance score, complication rate, tracheal intubation rate, and mortality rate were recorded at each observation time point of the two groups. Results The oxygenation index before NIV, at 4 h and at the end of NIV treatment of the helmet group were significantly increased from (160.29±50.32) mmHg to (249.29±83.47) mmHg and (259.24±87.09) mmHg; the oxygenation index of the facial mask group were increased from (168.63±38.63) mmHg to (225.00±74.96) mmHg and (217.69±77.80) mmHg, and there was no significant difference within the two groups (P <0.05). The respiratory rates before NIV, at 4 h and at the end of NIV treatment of the helmet group were obviously decreased from (27.60±7.64) breaths/min to (17.92±4.55) breaths/min and (16.88±3.90) breaths/min; the respiratory rates of the facial mask group were decreased from (24.68±6.14) breaths/min to (20.36±4.25) breaths/min and (19.68±3.34) breaths/min, and the differences within the two groups were statistically significant (P <0.05). However, there were no significant differences on oxygenation index and respiratory rates between the helmet group and facial mask group (P >0.05). Patients in the helmet was better tolerated than those in the facial mask group [ratio of good tolerance 96％ (24/25) vs 56％ (14/25) (P = 0.001) and fully tolerance 80％ (20/25) vs 36％ (9/25) (P =0.002)] and had less complications (1/25 vs 10/25, P = 0.002). 84％ patients in the helmet group and 76％ patients in the facial mask group were successfully weaned and discharged after NIV treatment (P =0.480). Conclusions Similar clinical efficacy in improving blood gas exchange and relieving dyspnea were observed in the helmet group and the facial mask group in patients with acute respiratory failure. However, the helmet is better tolerant, and had lower complication rate, which is especially suitable for patients with chest trauma combined with facial injuries.

Protetor Facial: relato de caso / Facial Mask: case report

A Odontologia do Esporte é uma nova especialidade odontológica, que tem, dentre os seus objetivos, prevenir, tratar e reabilitar atletas. Uma das atuações do cirurgião-dentista que atua nessa área é a confecção de protetores faciais e bucais individualizados. Atualmente, existe um maior número de investigação científica sobre protetores bucais que os faciais; consequentemente, os bucais são normatizados, e os faciais, ainda não. Eles são utilizados somente depois de o atleta ter sofrido traumas, porque evitam que o osso sofra refratura ou deslocamento, permitindo ao atleta não se manter temporariamente afastado da prática dos esportes...

La vía respiratoria en la reanimación cardiopulmonar y cerebral / Respiratory airway in brain and cardiopulmonary resuscitation

Introducción: acceder a la vía respiratoria constituye un elemento de vital importancia en la parada cardiaca. Tanto cuando los principios básicos establecidos para la reanimación eran el ABC por sus siglas en inglés (airway, breathing and circulation), como los del actual CAB (circulation, airway and breathing). Existen controversias entre la técnica utilizar de manera que se garantice de la mejor forma la ventilación: ¿intubación orotraqueal o dispositivos supraglóticos? Objetivo: realizar una actualización sobre las técnicas para acceder a la vía respiratoria en la reanimación cardiopulmonar y cerebral. Método: se visitó la página web de la Biblioteca Médica Nacional de los Estados Unidos (PubMed), con las siguientes palabras clave en inglés: airway AND reanimation y con el filtro activado para los últimos cinco años, en humanos y a texto completo. Conclusiones: la intubación traqueal requiere entrenamiento y práctica regular para evitar complicaciones. El personal poco entrenado no siempre tiene suficientes habilidades para lograrlo y no deberían perder tiempo realizando estos procedimientos y sí centrarse en las compresiones torácicas de alta calidad, la ventilación con bolsa y mascarilla, hasta la llegada de reanimadores expertos(AU)

Introduction: Accessing the airway is an element of vital importance in cases of cardiac arrest. Both when the basic principles established for resuscitation were the ABC (English acronym for airway, breathing and circulation), and for those of the current CAB (circulation, airway and breathing). There are controversies between the technique used to ensure ventilation the best way: orotracheal intubation or supraglottic devices? Objective: To carry out an update on the techniques to access the airway in cardiopulmonary and cerebral resuscitation. Method: We visited the website of the National Medical Library of the United States ( PubMed) with the following keywords in English: airway AND reanimation, and with the filter activated for the last five years, in humans and in full text. Conclusions: Tracheal intubation requires regular training and practice to avoid complications. The untrained staff members do not always have enough skills to achieve it and should not waste time doing these procedures, but focus on high-quality chest compressions, the ventilation bag and mask, instead, until the arrival of rescuer experts(AU)

Characterization and Short-Term clinical study of clay facial mask / Caracterização e estudo clínico de curta duração de máscara facial argilosa

Clay mineral facial masks are used to treat some dermatological diseases, just for cleansing or reduce the amount of oil secreted by sebaceous glands. There are several types of clays, which vary in mineralogical and chemical composition, color and origin. However, the literature lacks studies involving clay facial masks, in particular regarding their influence on skin´s biomechanical properties. Thus, this work aimed to characterize colored clays and evaluate its influence on skin frmness and elasticity by a short-term clinical study. Different clays (named in this study magnesium aluminum silicate - MAS, white, pink and green) were chemically characterized, and facial mask formulations were prepared. The short-term clinical study was performed through the application of formulations on the skin. The skin frmness and elasticity were assessed before treatment and after mask removal. The statistical analysis showed no signifcant influence of time or formulations in those parameters, although volunteers reported the sensation of mechanical tension after the removal of the clay facial masks. Thus, the composition of the different clays did not affect the skin viscoelasticity behavior in the short-term clinical study, and a long-term use of this type of formulation must be indicated to observe all the expected benefts.(AU)

Máscaras faciais argilosas são utilizadas para tratar algumas doenças dermatológicas, apenas para a limpeza ou reduzir a quantidade de óleo secretado pelas glândulas sebáceas. Existem vários tipos de argilas, que variam em composição mineral, química, cor e origem. No entanto, a literatura carece de estudos envolvendo máscaras faciais argilosas, em particular em relação a sua influência nas propriedades biomecânicas da pele. Assim, este trabalho teve como objetivo caracterizar argilas coloridas e avaliar sua influência sobre a frmeza e elasticidade da pele por meio de um estudo clínico de curto prazo. Diferentes argilas (chamadas neste estudo de silicato de alumínio e magnésio - MAS, branca, rosa e verde) foram caracterizadas quimicamente, e formulações de máscaras faciais foram preparadas. O estudo clínico de curto prazo foi realizado por meio da aplicação das formulações na pele. A frmeza e elasticidade da pele foram avaliadas antes do tratamento e após a remoção da máscara. A análise estatística mostrou nenhuma influência signifcativa do tempo ou das formulações nesses parâmetros, embora os voluntários tenham reportado sensação de tensão mecânica, após a remoção das máscaras faciais argilosas. Assim, a composição das diferentes argilas não afetou o comportamento visco-elástico da pele no estudo clínico de curto prazo, e uma utilização de longa duração poderia ser indicada com a fnalidade de se observar todos os benefícios esperados.(AU)

Paciente adulto com má oclusão padrão III tratada com auxílio de máscara facial: relato de caso / Adult patient with Class III malocclusion treated with facial mask therapy: case report

O objetivo do tratamento ortodôntico de pacientes adultos, além dos benefícios estéticos, deve levar em consideração os benefícios funcionais que elevam o grau de dificuldade do tratamento, já que não há mais mudanças proporcionadas pelo crescimento ósseo. O presente estudo relata o caso de uma paciente adulta com 32 anos e 2 meses com queixas estéticas e funcionais. As etapas do tratamento são apresentadas e, posteriormente, ilustradas com o caso clínico. Observou-se que a projeção dos dentes anteriores, em especial os incisivos, possibilitou maior liberdade de movimento da mandíbula. O paralelismo entre as raízes foi mantido ao final do tratamento. O alinhamento e o nivelamento foram alcançados com sucesso. As relações de Classe I de Angle nos molares e de chave de oclusão nos caninos foram mantidas em ambos os lados, assim como formato do arco e distâncias intermolares. O overbite e overjet foram corrigidos. Concluiu-se que a máscara facial, apesar de ser uma terapia comumente utilizada em pacientes com potencial de crescimento, mostrou-se versátil durante o tratamento da paciente com padrão III e os resultados estéticos e funcionais podem ser obtidos, desde que o correto diagnóstico, aliado à sensibilidade quanto às queixas dos pacientes ortodônticos, possam ser atingidos.

Orthodontic treatment of adult patients, in addition to aesthetic benefits, should take into consideration the functional benefits, which increase the difficulty of treatment since there are no more changes caused by bone growth. The present study reports the case of an adult patient with 32 years and 2 months with aesthetic and functional complaints. The steps of treatment are presented and then illustrated with photographs. The vestibular position of the anterior teeth, especially the incisors, allowed greater freedom of movement of the mandible. The parallelism between the roots was maintained after treatment. The alignment and leveling were successfully achieved. The Angle Class I relationships and the canines Class I were maintained on both sides, as well as the dental arch form and intermolar distances. Overbite and overjet were corrected. Facial mask, despite being a therapy commonly used in patients with growth potential, proved versatile for the treatment of patients with pattern III and the aesthetic and functional results can be achieved provided the correct diagnosis, combined with sensitivity as complaints of orthodontic patients, they can be obtained.

Physical and physicochemical stability evaluation of cosmetic formulations containing soybean extract fermented by Bifidobacterium animalis / Avaliação da estabilidade física e físico-química de formulações cosméticas contendo extrato de soja fermentado por Bifidobacterium animalis

Peel off facial masks, based on polyvinyl alcohol (PVA), are formulations that, after application and drying, form an occlusive film over the face. After removing, they provide cleanness, tensor and moisturizing effects, removing dead cells, residues and other materials deposited on the stratum corneous. The soybean extract fermented by Bifidobacterium animalis has sugars, amino acids, peptides, proteins and free isoflavonoids in high concentrations, when compared to the unfermented extract, providing benefits to the cosmetic formulations like anti-aging effect, moisture, tensor action and emollience. The cosmetic bases of peel off facial masks, added with 5.0 percent w/w of fermented soybean extract, were submitted to Preliminary and Accelerated Stability Studies. Eight (8) preparations were evaluated in several conditions of temperature (-10.0, 5.0, 22.0 and 45.0 ºC) and time (maximum of 15 days), comparing the results with the initial condition (48 h after preparation). The variables observed were: organoleptic characteristics, pH and appearing viscosity value and film drying time. The preparation containing 17.0 percent w/w of PVA and 0.5 percent w/w of guar gum was selected between the eight preparations initially prepared, because it presented the best performance in the stability test, being recommended storage at low temperatures (5.0 ºC).

As máscaras faciais peel off a base de álcool polivinílico (PVA) são formulações que, após a aplicação e secagem, formam um filme oclusivo sobre a face e, após sua remoção, conferem limpeza, ação tensora e hidratação à pele, retirando células mortas do estrato córneo, resíduos e outros materiais depositados. O extrato de soja fermentado por Bifidobacterium animalis possui açúcares, aminoácidos, peptídeos, e alto teor de isoflavonas na forma livre, quando comparado ao leite não fermentado, propiciando benefícios às formulações cosméticas, como ação antienvelhecimento, hidratação, efeito tensor e emoliência. As bases cosméticas de máscaras faciais peel off, acrescidas de extrato de soja fermentado 5,0 por cento p/p, foram submetidas aos ensaios de Estabilidade Preliminar e Acelerada, avaliando-se 8 preparações em diversas condições de temperatura (-10,0; 5,0; 22,0 e 45,0 ºC) e tempo (máximo de 15 dias), em relação à condição inicial (48 h após o preparo). As variáveis observadas envolveram: características organolépticas, valor de pH, viscosidade aparente e tempo de secagem do filme. A preparação contendo 17,0 por cento p/p de PVA e 0,5 por cento p/p de goma guar foi a selecionada dentre as oito preparações elaboradas inicialmente, por ter apresentado melhor desempenho no teste de estabilidade, sendo recomendado o armazenamento em temperatura reduzida (5,0 ºC).
