Cosmiatria: Uma análise do mercado brasileiro / Cosmiatry: An analysis of the Brazilian market

Introdução: O mercado de procedimento estéticos cresce exponencialmente no Brasil. Tal crescimento tem despertado o interesse de várias categorias profissionais. A decisão de praticar no setor deve considerar as oportunidades de mercado da localidade na qual se pretende atuar. Entretanto, a área carece de análises comparativas documentando prováveis diferenças regionais no país. O objetivo do estudo é descrever as diferenças de mercado em procedimentos estéticos entre os estados e regiões brasileiras. Um índice de potencial consumo de cosmiatria (IPCC) é calculado para tal análise comparativa. Método: Estudo transversal envolvendo prestadores de procedimentos estéticos não cirúrgicos no Brasil. Buscas no Google®-Google Maps® foram conduzidas usando termoschave e entrevistas telefônicas realizadas para obter informações sobre categorias profissionais, tipo de provedores e serviços oferecidos. Valores preditivos positivos foram obtidos para todas as estratégias de busca e usados para estimar o número total de provedores. O tamanho da população e a renda per capita foram considerados para o cálculo dos IPCCs para os estados brasileiros. Resultados: São Paulo, Minas Gerais e Rio de Janeiro apresentaram os maiores IPCCs, sendo 524, 210 e 180, respectivamente. Roraima teve um IPCC de 14, o mais baixo do país. A Região Sudeste apresentou, em média, o maior IPCC (242) entre todas as regiões brasileiras. Conclusão: Considerando o tamanho da população e a renda, a Região Sudeste apresenta as maiores oportunidades de mercado em procedimentos estéticos não cirúrgicos no Brasil. Nossos achados podem ser de interesse para profissionais de saúde e investidores que atuam ou pretendem atuar no setor.

Introduction: The aesthetic procedure market is growing exponentially in Brazil. This growth has aroused the interest of several professional categories. The decision to practice in the sector must consider the market opportunities in the location in which you intend to operate. However, the area lacks comparative analyses documenting probable regional differences in the country. The objective of the study is to describe market differences in aesthetic procedures between Brazilian states and regions. An index of potential cosmetic consumption (IPCC) is calculated for such a comparative analysis. Method: Cross-sectional study involving providers of nonsurgical aesthetic procedures in Brazil. Searches on Google Maps® were conducted using key terms, and telephone interviews were conducted to obtain information on professional categories, types of providers, and services offered. Positive predictive values were obtained for all search strategies and used to estimate the total number of providers. Population size and per capita income were considered to calculate the IPCCs for Brazilian states. Results: São Paulo, Minas Gerais, and Rio de Janeiro presented the highest IPCCs, being 524, 210, and 180, respectively. Roraima had an IPCC of 14, the lowest in the country. The Southeast Region presented, on average, the highest IPCC (242) among all Brazilian regions. Conclusion: Considering population size and income, the Southeast Region presents the greatest market opportunities for nonsurgical aesthetic procedures in Brazil. Our findings may be of interest to healthcare professionals and investors who work or intend to work in the sector.

Evaluation of facial pleasantness in patients with complete and unilateral cleft lip and palate rehabilitated and submitted to orofacial harmonization

ABSTRACT Objective: The objective of the present prospective case control study was to evaluate the facial pleasantness of patients with complete and unilateral cleft lip and palate at the end of interdisciplinary rehabilitation, submitted to facial fillers based on hyaluronic acid. Methods: The study group consisted of 18 individuals with complete unilateral cleft lip and palate, aged between 18 and 40 years (mean age 29 years) of both sexes. The patients presented a concave profile with mild to moderate maxillary deficiency, with completed orthodontic treatment and conducted by means of dentoalveolar compensations without orthognathic surgery. Participants underwent facial filling procedures with hyaluronic acid (HA) in the midface, inserted by a single operator. Standard photographs in frontal norm at rest, right profile at rest, and left profile at rest were obtained from each patient at the following operative times: (T1) pre-filler and (T2) and one-month post-filler. The photographs in T1 and T2 were randomly placed on a page of a virtual album. A 5-point Likert scale was used to assess facial pleasantness. The photographs were evaluated by two groups of evaluators consisting of 18 individuals with cleft lip and palate (CLPG=18) and 18 orthodontists with experience in the treatment of clefts (OG=18). For comparison between phases T1 and T2, and between evaluators with orofacial clefts and orthodontists, the Wilcoxon test was used (p<0,05). Results: People with cleft lip and palate rated their face as more pleasant after the midface filling procedure. In the perception of the orthodontists, on the other hand, the facial pleasantness remained similar after the facial filling procedure. Conclusions: The filling of the middle third of the face in patients with cleft lip and palate treated without orthognathic surgery increased the pleasantness of the face in the opinion of laypeople with cleft lip and palate.

RESUMO Objetivo: O objetivo do presente estudo caso-controle prospectivo foi avaliar a agradabilidade facial de pacientes com fissura labiopalatina completa e unilateral ao final da reabilitação interdisciplinar, submetidos a preenchimentos faciais à base de ácido hialurônico. Métodos: O grupo de estudo foi composto por 18 indivíduos com fissura labiopalatina unilateral completa, com idade entre 18 e 40 anos (média de 29 anos), de ambos os sexos. Os pacientes apresentavam perfil côncavo com deficiência maxilar leve a moderada, com tratamento ortodôntico concluído e realizado por meio de compensações dentoalveolares sem cirurgia ortognática. Os participantes foram submetidos a procedimentos de preenchimento facial com ácido hialurônico (AH) no terço médio da face, implantado por um único operador. Fotografias padrão em norma frontal em repouso, perfil direito em repouso e perfil esquerdo em repouso foram obtidas de cada paciente nos seguintes tempos operatórios: (T1) pré-preenchimento e (T2) um mês pós-preenchimento. As fotografias em T1 e T2 foram inseridas aleatoriamente em uma página de um álbum virtual. Uma escala Likert de 5 pontos foi utilizada para avaliar a agradabilidade facial. As fotografias foram avaliadas por dois grupos de avaliadores formados por 18 indivíduos com fissura labiopalatina (GFLP=18) e 18 ortodontistas com experiência no tratamento de fissuras (GO=18). Para comparação entre as fases T1 e T2, e entre avaliadores com fissura labiopalatina e ortodontistas, foi utilizado o teste de Wilcoxon (p<0,05). Resultados: As pessoas com fissura labiopalatina avaliaram seu rosto como mais agradável após o preenchimento do terço médio da face. Já na percepção do ortodontista, a agradabilidade facial permaneceu semelhante após o procedimento de preenchimento facial. Conclusões: O preenchimento do terço médio da face em pacientes com fissura labiopalatina tratados sem cirurgia ortognática aumentou a agradabilidade da face na opinião dos leigos com fissura labiopalatina.

Short-term qualitative and quantitative analyses of preseptal injection of hyaluronic acid on the treatment of acquired lower eyelid cicatricial ectropion / Análise preliminar qualitativa e quantitativa da injeção pré-septal de ácido hialurônico para tratamento do ectrópio cicatricial adquirido da pálpebra inferior

ABSTRACT Purpose: Recently, hyaluronic acid (HA) was proposed as a promising option for the treatment of acquired lower eyelid cicatricial ectropion. However, this effect was not confirmed by quantitative assessments. This study aimed to assess the effect of hyaluronic acid on the treatment of acquired lower eyelid cicatricial ectropion. Methods: Eight patients with acquired lower eyelid cicatricial ectropion (13 eyelids) were treated with a single 1 mL injection of hyaluronic acid in the preseptal area of the lower eyelid. Evaluation of symptoms and biomicroscopic exam was performed before and 30 days after hyaluronic acid injection. Quantitative analysis of the lower eyelid position (with and without lid traction) was determined before and 30 days after hyaluronic acid injection through standard photographs analyzed using the ImageJ. Results: All patients experienced partial improvement of symptoms. The lower eyelid position was significantly lifted after hyaluronic acid injection with a significant reduction of medial and lateral angles, reduction of the margin reflex distance, and total and medial ocular fissure area. However, signs of lid margin inflammation and corneal punctate keratitis persisted. Conclusions: Hyaluronic acid injected in the pre-septal area of the lower eyelid improved acquired lower eyelid cicatricial ectropion symptoms and significantly lifted the position of the lower eyelid. Further studies, with a large number of participants and a long-term follow-up period, are needed to better determine the permanency of the effects of hyaluronic acid injections on the treatment of acquired lower eyelid cicatricial ectropion.

RESUMO Objetivo: Recentemente, o ácido hialurônico foi proposto como promissor no tratamento do ectrópio cicatricial adquirido da pálpebra inferior. No entanto, não foram feitas avaliações quantitativas para confirmar este efeito, motivo que levou a realização do presente estudo que visou avaliar o efeito do ácido hialurônico no tratamento do ectrópio cicatricial adquirido da pálpebra inferior. Métodos: Oito portadores de ectrópio cicatricial adquirido da pálpebra inferior (13 pálpebras) foram tratados com uma única dose de 1 mL de ácido hialurônico, injetada na área pré-septal da pálpebra inferior. Os sintomas e o exame biomicroscópico foram realizados antes e 30 dias após a injeção do ácido hialurônico. A análise quantitativa da posição palpebral inferior (com e sem tração palpebral) foi determinada antes e 30 dias após a injeção do ácido hialurônico por meio de fotografias que foram analisadas usando o programa ImageJ. Resultados: Todos os pacientes apresentaram melhora parcial dos sintomas. A posição da pálpebra inferior foi elevada significativamente após a injeção do ácido hialurônico, com redução significativa dos ângulos medial e lateral, da distância entre o reflexo pupilar e a margem da pálpebra inferior, da área de fissura palpebral total e da área medial. No entanto, sinais de inflamação da margem palpebral e ceratite puntata da córnea persistiram. Conclusões: O ácido hialurônico injetado na área pré-septal da pálpebra inferior, melhorou os sintomas do ectrópio cicatricial adquirido da pálpebra inferior e elevou significativamente a posição da pálpebra inferior. Estudos com maior número de participantes e período de acompanhamento mais longo são necessários para melhor determinar os efeitos das injeções de ácido hialurônico a longo prazo no tratamento do ectrópio cicatricial adquirido da pálpebra inferior.

Hyaluronic Acid Dermal Fillers for Treatment of Congenital and Acquired Lip Asymmetries and Deformities

Hyaluronic acid (HA) dermal fillers are widely used in aesthetic treatments for facial and lip modeling. Despite HA fillers has largely known to be use in procedures for augmentation the lip volume, their application to management lip abnormalities is not widespread. This study reviewed the use of HA fillers for reconstruction of congenital and acquired li p asymmetries and deformities, searching to expand knowledge about this treatment modality. To undertake this narrative review, the Medline-Pubmed, Web of Science, Scopus, Embase, Google Schoolar e Lillacs databases were searched. Several studies have reported positive results in the use of HA fillers for the treatment of lip deformities caused by different factors such as: Insatisfactory dermal fillers, permanent lip implants, excision of lip carcinoma, post-operative scars and electrical burns. HA fillers are also an alternative for the management of lip asymmetries and residual surgical scars in patients with cleft lip. Moreover, injection of HA fillers in individuals with facial paralysis and facioscapulohumeral muscular dystrophy can also improve lip incompetence. Additionally, HA fillers can be used as a complementary treatment in cases of severe malocclusion associated with skeletal changes, helping to maintain the seal and refine the lip appearance. Therefore, HA fillers can be used as alternative treatment for several types of congenital and acquired lip deformities and asymmetries. However, it is necessary to carry out randomized clinical trials with a greater number of patients and follow-up time, in order to investigate the benefits of the HA fillers for carriers patients of lip abnormalities.

Los rellenos dérmicos de ácido hialurónico (AH) son muy utilizados en tratamientos estéticos para el modelado facial y de labios. A pesar de que se sabe en gran medida que los rellenos de HA se utilizan en procedimientos para aumentar el volumen de los labios, su aplicación para el tratamiento de anomalías labiales no está muy extendida. Este estudio revisó el uso de rellenos de HA para la reconstrucción de asimetrías y deformidades labiales congénitas y adquiridas, buscando ampliar el conocimiento sobre esta modalidad de tratamiento. Para realizar esta revisión narrativa, se realizaron búsquedas en las bases de datos Medline-Pubmed, Web of Science, Scopus, Embase, Google Schoolar y Lillacs. Varios estudios han reportado resultados positivos en el uso de rellenos de HA para el tratamiento de deformidades labiales causadas por diferentes factores tales como: rellenos dérmicos insatisfactorios, implantes labiales permanentes, escisión de carcinoma labial, cicatrices postoperatorias y quemaduras eléctricas. Los rellenos de HA también son una alternativa para el manejo de asimetrías labiales y cicatrices quirúrgicas residuales en pacientes con labio hendido. Además, la inyección de rellenos de HA en personas con parálisis facial y distrofia muscular facioescapulohumeral también puede mejorar la incompetencia de los labios. Además, los rellenos de HA se pueden usar como un tratamiento complementario en casos de maloclusión severa asociada con cambios esqueléticos, lo que ayuda a mantener el sellado y refinar la apariencia de los labios. Por lo tanto, los rellenos de HA se pueden utilizar como tratamiento alternativo para varios tipos de deformidades y asimetrías labiales congénitas y adquiridas. Sin embargo, es necesario realizar ensayos clínicos aleatorizados con mayor número de pacientes y tiempo de seguimiento, para investigar los beneficios de los rellenos HA para pacientes portadores de anomalías labiales.

Recubrimiento radicular de recesiones gingivales con matriz dérmica acelular / Root coverage of gingival recession with acellular dermal matrix

La recesión gingival es considerada como una deformidad o condición mucogingival, la Academia Americana de Periodontología, define a la recesión gingival como el desplazamiento del margen del tejido blando apical a la unión cemento-esmalte con la exposición de la superficie radicular. El tratamiento de las recesiones gingivales es un motivo de consulta común debido a razones estéticas, hipersensibilidad dentinaria, molestias durante el cepillado e incluso temor a la pérdida dentaria. Es una situación clínica común, 60% de la población humana tiene algún tipo de recesión gingival. Al realizar el examen clínico a paciente masculino de 55 años, se observó una recesión gingival tipo 1 (RT1) sin pérdida de inserción interproximal de la clasificación de Cairo. Se realizó el colgajo posicionado coronalmente (CPC) utilizando una matriz dérmica acelular (MDA) de origen humano OrACELL®. Se obtuvo resultado favorable en el recubrimiento de recesiones gingivales múltiples; considerándolos como una buena alternativa frente a los injertos gingivales autógenos. Concluyendo que, el uso de la matriz dérmica acelular para el tratamiento de la recesión gingival tipo 1 es una adecuada opción para el recubrimiento radicular. Se recomiendan más estudios a largo plazo para ver la estabilidad de los resultados obtenidos con la MDA (AU)

Gingival recession, considered a deformity or mucogingival condition, the American Academy of Periodontology, defines gingival recession as the exposure of the root surface resulting from migration of the gingival margin apical to the cementoenamel junction (CEJ). The treatment of gingival recessions is a common reason for consultation due to aesthetic reasons, dentin hypersensitivity, discomfort during brushing and even fear of tooth loss. It is a common clinical situation, 60% of the human population has some kind of gingival recession. Clinical examination of a 55-year-old male patient showed a type 1 gingival recession (RT1) without loss of interproximal insertion of the Cairo classification. Coronally advanced flap (CAF) was performed using an acellular dermal matrix (ADM) of human origin OrACELL®. Favorable results were obtained in the coating of multiple gingival recessions; considering them as a good alternative to autogenous gingival grafts. Concluding that, the use of the acellular dermal matrix for the treatment of gingival recession type 1, is a suitable option for root lining. Further long-term studies are recommended to see the elasticity of MDA outcomes (AU)

Percepção da redução do tamanho após rinoplastia de aumento não cirúrgica: Análise retrospectiva de 116 casos / Perception of size reduction after non-surgical augmentation rhinoplasty: Retrospective analysis of 116 cases

Introdução: Tradicionalmente, o rebaixamento do dorso é o único método de correção da giba. Raras séries apontam a elevação do radix como possível solução. O que explica essa maciça predominância do procedimento redutor? Ineficácia dos métodos de aumento de radix e ponta? Percepção de nariz grande com os procedimentos de aumento? Nossos objetivos são descobrir se a percepção de redução ocorre na rinoplastia não cirúrgica (RNC), feita exclusivamente com adição de volume, e se a percepção de redução é importante na RNC. Método: Análise retrospectiva de 116 pacientes consecutivos submetidos a RNC. As imagens dos pacientes foram analisadas por 12 observadores independentes que avaliaram as mudanças percebidas no tamanho do nariz e a qualidade da correção, dando notas de 1 a 10 para os dois quesitos. Quanto ao tamanho, 1 representava muito menor que antes, 5 mesmo tamanho (neutralidade) e 10 muito maior que antes. A qualidade da correção foi classificada de 1 a 10. Resultados: 92 casos (79%) foram percebidos como redução do tamanho, enquanto 20 casos (17%) foram percebidos como aumento. Houve percepção de redução na média das pontuações de tamanho (4,71). A média da qualidade da correção foi de 8,28 na escala de 1 a 10. Ademais, nossos resultados sugerem que pode haver correlação indireta entre a percepção do tamanho e a qualidade da correção. Conclusão: O aumento proporcionado pela RNC pode causar percepção de redução do tamanho do nariz, e o grau da redução percebida pode estar diretamente relacionado ao grau de qualidade percebida da correção.

Introduction: Traditionally, lowering the dorsum is the only method of hump correction. Rare series point to raising the radix as a possible solution. What explains this massive predominance of the reduction procedure? Ineffectiveness of radix and tip augmentation methods? Big nose perception with augmentation procedures? Our objectives are to determine if the perception of reduction occurs in non-surgical rhinoplasty (NSR), performed exclusively with volume addition, and if the perception of reduction is important in NSR. Method: Retrospective analysis of 116 consecutive patients undergoing NSR. The patients' images were analyzed by 12 independent observers who evaluated the perceived changes in the nose's size and the correction's quality, giving scores from 1 to 10 for both questions. As for size, 1 represented much smaller than before, 5 same size (neutrality), and 10 much larger than before. The quality of correction was graded from 1 to 10. Results: 92 cases (79%) were considered size reduction, while 20 cases (17%) were considered enlargement. There was a perception of a reduction in the average size scores (4.71). The mean correction quality was 8.28 on a scale of 1 to 10. Furthermore, our results suggest that there may be an indirect correlation between perceived size and correction quality. Conclusion: The increase provided by the NSR can cause a perception of a reduction in the size of the nose, and the degree of perceived reduction can be directly related to the degree of perceived quality of the correction.

A Delphi consensus on the nomenclature and diagnosis of lichen planus pigmentosus and related entities

Background: Although well known in clinical practice, research in lichen planus pigmentosus and related dermal pigmentary diseases is restricted due to lack of consensus on nomenclature and disease definition. Aims and Objectives: Delphi exercise to define and categorise acquired dermal pigmentary diseases. Methods: Core areas were identified including disease definition, etiopathogenesis, risk factors, clinical features, diagnostic methods, treatment modalities and outcome measures. The Delphi exercise was conducted in three rounds. Results: Sixteen researchers representing 12 different universities across India and Australia agreed to be part of this Delphi exercise. At the end of three rounds, a consensus of >80% was reached on usage of the umbrella term ‘acquired dermal macular hyperpigmentation’. It was agreed that there were minimal differences, if any, among the disorders previously defined as ashy dermatosis, erythema dyschromicum perstans, Riehl’s melanosis and pigmented contact dermatitis. It was also agreed that lichen planus pigmentosus, erythema dyschromicum perstans and ashy dermatosis did not differ significantly apart from the sites of involvement, as historically described in the literature. Exposure to hair colours, sunlight and cosmetics was associated with these disorders in a significant proportion of patients. Participants agreed that both histopathology and dermatoscopy could diagnose dermal pigmentation characteristic of acquired dermal macular hyperpigmentation but could not differentiate the individual entities of ashy dermatosis, erythema dyschromicum perstans, Riehl’s melanosis, lichen planus pigmentosus and pigmented contact dermatitis. Limitations: A wider consensus involving representatives from East Asian, European and Latin American countries is required. Conclusion: Acquired dermal macular hyperpigmentation could be an appropriate conglomerate terminology for acquired dermatoses characterised by idiopathic or multifactorial non-inflammatory macular dermal hyperpigmentation

Angiotropic melanocytes: Possibly a distinctive finding in extra-facial acquired dermal melanocytosis

Background: Acquired dermal melanocytosis is a heterogenous group of hyperpigmented lesioins which predominantly involve the face. Aim: The aim of this study was to study the clinical presentation and histopathology of cases with extra-facial acquired dermal melanocytosis. Methods: Retrospective record analysis was performed between May 2016 to August 2019 to retrieve cases of extra-facial acquired dermal melanocytosis seen at the out-patient department of dermatology at the All India Institute of Medical Sciences, Jodhpur. Consecutive cases with histopathologically proven diagnosis of acquired dermal melanocytosis were included. Documentation of variation in clinical presentation and histopathologic findings was done in light of the existing literature. Results: Overall, four cases of extra-facial acquired dermal melanocyosis (female:male = 1:3) were seen during the study period. The lone case on head and neck involved the ear lobule and peri-auricular area. The other three cases had involvement of the hand. The histopathology confirmed the diagnosis of dermal melanocytosis but revealed peculiar findings of angiotropic melanocytes and dilated capillaries. Limitations: Small sample size and lack of comparison with perilesional normal skin were the limitations of this study. Conclusion: The findings of angiotropic melanocytes may be unique to extra-facial acquired dermal melanocytosis. This might indicate interaction between dermal melanocytes and capillary endothelial cells. This finding along with dermal capillary ectasia may indicate a possible role for vascular lasers in the management of these disorders

Relato de caso clínico de preenchimento labial com ácido hialurônico e avaliações volumétricas através de software de análise facial 3d / Clinical case report of hyaluronic acid lip filler and volumetric evaluations using 3d facial analysis software / Reporte de caso clínico de relleno labial con ácido hialurónico y evaluaciones volumétricas utilizando software de análisis facial 3d

A análise facial consiste em uma etapa importante do diagnóstico e avaliação dos resultados obtidos na harmonização orofacial. Para avaliação dos resultados de procedimentos estéticos, fotografias são muito utilizadas, porém novas ferramentas são necessárias para facilitar a visualização dos pacientes quanto aos ganhos estéticos. Os scanners faciais 3D surgem como alternativa para tal finalidade. O objetivo deste estudo foi analisar, através de fotografias e escaneamento 3D da face, o ganho de volume labial após intervenção de preenchimento. A paciente apresentava insatisfação com relação aos seus lábios. Durante a avaliação, constatou-se ausência de volume e contorno labial. Antes de iniciar o procedimento, realizou-se protocolo fotográfico e escaneamento facial (E1). Para o procedimento, foi utilizada uma seringa de 1 mL de ácido hialurônico. O escaneamento foi feito no pós-imediato (E2), após 10 dias (E3) e após 40 dias da intervenção (E4). Nesta mesma consulta após 40 dias, foi realizado injeção da segunda seringa de ácido hialurônico escaneamento do pós-imediato (E5). Após 40 dias, a paciente voltou (E6). Após análise comparativa das malhas, foi possível verificar ganho de 3 mm entre E1 e E2. Na comparação do pré (E1) e após 10 dias (E3), verificou-se volumização total de 1,85 mm, demonstrando que quase 40% do volume no pós-imediato é edema. Em E6, após 40 dias da aplicação da segunda seringa, foi possível quantificar ganho de 2,12 mm no lábio superior quando comparado a E1. Pode-se concluir que o escaneamento 3D contribui expressivamente para avaliação dos resultados alcançados em procedimentos estéticos.

Facial analysis is an important stage in the diagnosis and evaluation of the results obtained in orofacial harmonization. To evaluate the results of aesthetic procedures, photographs are widely used, but new tools are needed to facilitate patient visualization of aesthetic gains. 3D facial scanners have emerged as an alternative for this purpose. The aim of this study was to analyze, by means of photographs and 3D facial scanning, the labial volume gain after a filling intervention. The patient was dissatisfied with her lips. During the evaluation, it was observed the absence of lip volume and contour. Before starting the procedure, a photographic protocol and facial scanning (S1) were performed. A 1 mL syringe of hyaluronic acid was used for the procedure. The scanning was done post-immediately (S2), 10 days (S3) and 40 days after the intervention (S4). In the same appointment after 40 days, the second syringe of hyaluronic acid was injected and scanned post-immediate (S5). After 40 days, the patient returned (E6). After comparative mesh analysis, it was possible to verify a 3 mm gain between S1 and S2. In the comparison of pre (S1) and after 10 days (S3), there was a total volumization of 1.85 mm, showing that almost 40% of the volume in the post-immediate period is edema. In S6, 40 days after the application of the second syringe, it was possible to quantify a gain of 2.12 mm in the upper lip when compared to S1. It can be concluded that 3D scanning contributes expressively to the evaluation of the results achieved in aesthetic procedures.

En la misma consulta, a los 40 días, se realizó la inyección de la segunda jeringa de ácido hialurónico tras la exploración inmediata (S5). A los 40 días, la paciente regresó (E6). Tras el análisis comparativo de las mallas, se pudo comprobar una ganancia de 3 mm entre S1 y S2. En la comparación del pre (S1) y después de 10 días (S3), hubo una volumización total de 1,85 mm, demostrando que casi 40% del volumen post-immediato es edema. En S6, 40 días después de la aplicación de la segunda jeringa, fue posible cuantificar una ganancia de 2,12 mm en el labio superior en comparación con S1. Se puede concluir que el escaneo 3D contribuye expresivamente para la evaluación de los resultados alcanzados en procedimientos estéticos.

Total Glucosides of Paeony Regulate Immune Imbalance Mediated by Dermal Mesenchymal Stem Cells in Psoriasis Mice / 中国结合医学杂志

OBJECTIVE@#To investigate the therapeutic effects of total glucosides of paeony (TGP) on psoriasis based on the immunomodulatory effect of dermal mesenchymal stem cells (DMSCs).@*METHODS@#A total of 30 male BALB/c mice were divided into 6 groups (n=5 in each) by a random number table method, including control, psoriasis model (model, 5% imiquimod cream 42 mg/d), low-, medium- and high-dose TGP (50, 100, and 200 mg/kg, L, M-, and H-TGP, respectively), and positive control group (2.5 mg/kg acitretin). After 14 days of continuous administration, the skin's histopathological changes, apoptosis, secretion of inflammatory cytokines, and proportion of regulatory T cells (Treg) and T helper cell 17 (Th17) were evaluated using hematoxylin-eosin (HE) staining, TdT-mediated dUTP nick end labeling staining, enzyme-linked immunosorbent assay, and flow cytometry, respectively. DMSCs were further isolated from the skin tissues of normal and psoriatic mice, and the cell morphology, phenotype, and cycle were observed. Furthermore, TGP was used to treat psoriatic DMSCs to analyze the effects on the DMSCs immune regulation.@*RESULTS@#TGP alleviated skin pathological injury, reduced epidermis layer thickness, inhibited apoptosis, and regulated the secretion of inflammatory cytokines and the proportion of Treg and Th17 in the skin tissues of psoriatic mice (P<0.05 or P<0.01). There was no significant difference in cell morphology and phenotype between control and psoriatic DMSCs (P>0.05), however, more psoriatic DMSCs remained in G0/G1 phase compared with the normal DMSCs (P<0.01). TGP treatment of psoriatic DMSCs significantly increased cell viability, decreased apoptosis, relieved inflammatory response, and inhibited the expression of toll-like receptor 4 and P65 (P<0.05 or P<0.01).@*CONCLUSION@#TGP may exert a good therapeutic effect on psoriasis by regulating the immune imbalance of DMSCs.

Effects of topical application of virgin coconut oil on infection, mortality and dermal maturation in preterm newborns: Systematic review and meta-analysis

Background@#Preterm birth is an important health concern in countries with limited resources and healthcare access. Topical therapy may be effective for improving outcomes in preterm neonates whose skin barriers are compromised due to immaturity.@*Objectives@#To systematically review the topical VCO's effects in preterm infants on infection, mortality, and dermal maturity.@*Methodology@#Systematic review and meta-analysis of RCTs of topical VCO in preterm infants were conducted. Databases included PubMed, Google Scholar, Clinical trials.gov, Trip, Cochrane Library, and HERDIN. The risk of bias was assessed by two authors independently. RR with 95% CI was used for the pooled estimate of dichotomous outcomes including infection prevention, mortality reduction, and skin irritation. Mean differences with 95% CI were used for the pooled estimate of weight loss and NSCS.@*Results@#Of 110 records identified, 3 RCTs with 2440 patients were included. Prevention of infection had a trend toward VCO (RR = 0.90, [95% CI: 0.64, 1.27] while the results for mortality reduction were inconclusive (RR = 0.45, [95% CI: 0.06, 3.38]. NSC scores showed a beneficial trend toward VCO (RR = -0.03, [95% CI: -0.16, 0.09]. Both secondary outcomes of skin irritation and weight loss had inconclusive results.@*Conclusions@#This review showed the lack of evidence of the effectiveness of topical VCO in improving various outcomes in premature infants. The effects on infection prevention and dermal maturation were favorable. However, its effects on preventing mortality, skin irritation, and weight loss were inconclusive.

K.I.S.S. technique: sistematização para um preenchimento labial simples e seguro / K.I.S.S. Lip Filler Technique - keeping injections simple and safe when filling lips

Para tornar o preenchimento labial mais simples e seguro, desenvolvemos a técnica de preenchimento labial K.I.S.S. - Keep Injection Simple and Safe. Para ser simples, a técnica recomenda apenas a avaliação de quatro parâmetros anatômicos e o preenchimento de cinco áreas labiais. Por segurança, a injeção é realizada apenas no plano supramuscular, por meio de cânulas de ponta romba, inseridas a partir de quatro portas de entrada, duas no lábio superior e duas no lábio inferior. O preenchimento é realizado em vetores anatômicos específicos para volumização, projeção, melhora do contorno e sustentação do arco do cupido e comissuras labiais

To simplify the procedure and increase lip augmentation safety, we have developed the KISS - Keep Injection Simple and Safe lip filler technique. To be simple, the method recommends only the evaluation of four anatomical parameters and the filling of five labial areas. To be safe, the injection is performed only in the supramuscular plane, using cannulas with a blunt tip, inserted in four entries: two in the upper lip and two in the lower lip. Fillers are injected in specific anatomical vectors for lips volumization, projection, contour improvement, and support of cupid's bow and lip corners

Correlação entre a linguagem de lipoenxertia e de preenchimento facial com ácido hialurônico / Correlation between facial lipofilling and hyaluronic acid filling languages

Introdução: A perda de volume é a principal causa da aparência de envelhecimento. Assim, a demanda por materiais de preenchimento que sejam seguros, duradouros e biocompatíveis tem crescido, com ênfase na lipoenxertia. Porém, algumas questões relativas à padronização ainda não estão claras, como áreas a serem injetadas e volumes. Assim, busca-se analisar os resultados de uma série de casos e sistematizar os volumes de preenchimento a serem utilizados, bem como correlacionar a linguagem usada na lipoenxertia facial com a do MD Codes®. Métodos: Revisão dos prontuários de pacientes que realizaram lipoenxertia facial. A seleção da área doadora foi procedida com base em critérios de conveniência, como facilidade de posicionamento, abundância de material e o contorno corporal do paciente. A colheita foi por aspiração manual. A preparação foi feita pela técnica de Coleman. Áreas de aplicação: para traçar um paralelo entre os conhecimentos adquiridos com a lipoenxertia facial e o preenchimento com material sintético, foi utilizada a nomenclatura utilizada nos MD Codes®. Resultados: Foram incluídos 54 lipoenxertos faciais (11% homens / 88,88% mulheres). Idade média de 43,94 anos (20 a 71, desvio padrão 11,21). O tempo médio de acompanhamento foi 155,61 dias (variação de 7-543, desvio padrão 156,05). Não houve complicações relacionadas ao método. O volume médio injetado foi de 29,83ml (intervalo 6-53,9, desvio padrão 12,07). Conclusão: A lipoenxertia autóloga é um procedimento factível para alguns casos de rejuvenescimento facial. A linguagem MD Codes® pode ser usada em paralelo com a descrição anatômica das regiões injetadas neste estudo.

Introduction: As has been demonstrated, volume loss is a primary cause of aging appearance. So, the demand for filling materials that are safe, long-lasting, and biocompatible has grown, increasing the emphasis on lipografting. However, some issues regarding standardization are still unclear, like areas to be injected and volumes. So, the main objective is to analyze the results of a case series and systematize the filler volumes to be used and correlate the language used in facial lipografting with that used in MD Codes®. Methods: Review the medical records of those who underwent facial fat grafting. Selection of donor area was proceeded based on convenience criteria, which assesses the ease of positioning, the abundance of material, and the patient's body contour. Harvesting was by manual aspiration. Preparation was done by Colemans' technique. Application areas: To draw a parallel between the knowledge acquired with facial lipografting and the fillings using synthetic material, the nomenclature used in MD Codes® was used. Results: 54 facial lipografting were included (11% men / 88.88% women). The average age is 43.94 years (20 to 71, standard deviation 11.21). Follow-up average time was 155.61 days (range 7-543, standard deviation 156.05). There were no complications related to the method. The mean volume injected was 29.83ml (range 6-53.9, standard deviation 12.07). Conclusion: Autologous lipografting is a feasible procedure for certain cases of facial rejuvenation. The MD Codes® language can be used in parallel with the anatomical description of the injected regions in this study.

Introduction. A cranial dermal sinus is a tubular tract resulting from the incomplete separation of the epithelial ectoderm from the neuroectoderm which may lead to infectious complicationsThere have been isolated reports of this condition. Objective. To describe a series of patients with cranial dermal sinus, its presentation, diagnosis, management, and complications. Population and methods. Observational,descriptive study of a series of pediatric patients with cranial dermal sinus treated at a tertiary care children's hospital between 2014 and 2019. Results. A total of 18 patients were included. Theclinical presentation was a specific lesion on the scalp in 12 cases, intracranial hypertension in 4, ataxia in 1, and a specific lesion with fistula tract in 1. Half of patients had symptoms of infection. The lesion was located in the midline of the occipital bone in 13 cases; in the midline of the frontal bone in 3 cases; and in the interparietal midline in 2 cases. The dermal sinus was associated with anextracranial image in 5 cases and an intracranial complication in 11 cases. No patient hadrecurrence and only one surgery was performed in all of them. Conclusions. In this series, dermal sinusespresented as specific lesions on the scalp. The most common site was the occipital midline, and more than 50% of these extended through the bone. The treatment of choice was complete resection of dermal sinus and associated lesions. An emergency surgery was performed when the dermal sinus was symptomatic or associated with intracranial lesions.

Visual loss after aesthetic facial filler injection: a literature review on an ophthalmologic issue / Perda visual após preenchimento facial estético: uma revisão da literatura sobre complicações oftalmológicas

ABSTRACT Dermal filler injection is among facial rejuvenation treatments that have been increasingly used. Despite being a minimally invasive procedure, it can lead to severe complications such as blindness. A review of all cases of filler- -induced visual loss in the world literature was conducted to summarize the mechanisms, anatomical considerations, and clinical ophthalmologic course, current strategies of prevention and management, and trends over the years. We identified 233 cases of filler-induced visual loss, and 172 patients had a severe visual impairment in at least one eye. The typical patients are young women who received injections of hyaluronic acid or autologous fat in the glabella or nose, and the typical presentations were sudden ocular pain, ptosis, and ophthalmoplegia due to vascular occlusion. The findings of this study also suggest an increase in the number of unlicensed professionals performing the procedure. Even though the continued development of dermal fillers has improved the treatment options available, further studies and strategies are necessary to reduce the incidence and minimize the consequences of filler-induced visual loss.

RESUMO O uso de preenchedores dérmicos é uma prática bem estabelecida de rejuvenescimento facial. Embora seja um procedimento minimamente invasivo, pode levar a complicações graves como cegueira. Uma revisão de casos de perda visual pós preenchimento facial estético foi conduzida para descrever os mecanismos, considerações anatômicas, quadro oftalmológico, atuais estratégias de prevenção e manejo, e tendências ao longo dos anos. Foram identificados 233 casos, e 172 pacientes tiveram ao menos um olho com baixa visão ao final do seguimento. O paciente típico é uma mulher jovem submetida a preenchimento de ácido hialurônico na glabela ou nariz, apresentando dor ocular súbita, ptose e oftalmoplegia devido à oclusão vascular. Este estudo também destaca um possível aumento de profissionais não habilitados realizando este procedimento. Apesar do contínuo desenvolvimento dos preenchedores dérmicos e aprimoramento das opções de tratamento disponíveis, mais estudos e estratégias são necessários para reduzir a incidência de complicações e minimizar suas consequências.

Liposomal amphotericin B is more effective in polymorphic lesions of post kala-azar dermal leishmaniasis

Background: Post kala-azar dermal leishmaniasis (PKDL) is thought to be the reservoir of infection for visceral leishmaniasis in South Asia. The development of strategies for the diagnosis and treatment of PKDL are important for the implementation of the visceral leishmaniasis elimination program. Aims: Liposomal amphotericin B (L-AMB) has been an overwhelming success in the treatment of visceral leishmaniasis. However, the empirical three-week regimen of L-AMB proposed for PKDL was shown to be inadequate, especially in the macular variant. This study aimed to delineate response of the different variants of PKDL to L-AMB. Methods: Skin biopsies were collected from PKDL cases at disease presentation and upon completion of treatment with L-AMB. Parasite DNA was detected by Internal Transcribed Spacer-1 PCR (ITS-1 PCR) and quantified by amplification of parasite kDNA. CD68 + macrophages were estimated in tissue sections by immunohistochemistry. Results: Treatment with L-AMB decreased the parasite load by 97% in polymorphic cases but only by 45% in macular cases. The median parasite load (89965 vs 5445 parasites/μg of genomic DNA) as well as infiltration by CD68+ cells before treatment was much greater in the polymorphic cases. Limitations: Although monitoring of the parasite load for 12 months post-treatment would have been ideal, this was not possible owing to logistical issues as well as the invasive nature of biopsy collection procedure. Conclusion: A dramatic decrease in the parasite burden was noted in patients with polymorphic lesions. Although patients with macular disease also had a decrease in parasite burden, this was not as marked as in the polymorphic cases. There was also a significantly greater infiltration of CD68 + macrophages in polymorphic PKDL before therapy

Reconstrução do antebraço com matriz dérmica acelular após excisão de neurofibroma plexiforme gigante: relato de casos / Forearm reconstruction with acellular dermal matrix after giant plexiform neurofibroma excision: case reports

Introdução: O neurinoma plexiforme gigante é um neuroectoderma e uma doença hereditária. É um tumor cutâneo incomum associado à NF1, caracterizado como um tumor benigno da bainha do nervo periférico envolvendo múltiplos fascículos nervosos. Os objetivos da reconstrução da cobertura do antebraço são proteger as estruturas que vão até o punho e a mão e evitar cicatrizes que levem à perda de movimento. Tanto o antebraço quanto a mão desempenham papéis funcionais e sociais. O manejo bem-sucedido de feridas complexas é necessário para a reabilitação funcional geral desses pacientes. Relato do Caso: Paciente do sexo feminino, 31 anos, apresentou-se na divisão de cirurgia plástica com neurofibroma plexiforme gigante no antebraço direito. Após ressecção cuidadosa, todos os tendões anteriores do antebraço foram expostos. O defeito foi coberto com Pelnac T enxertável (espessura de 3mm e tamanho 12 X 24cm2), fixados com pontos monocryl 4-0. Após 10 dias, a matriz dérmica acelular foi removida e um enxerto de malha de pele de espessura parcial foi colocado. No dia 7, a matriz dérmica acelular apresentou bons sinais de ingestão. No dia 17, observamos uma sobrevida do enxerto de 95%. No seguimento de 3 meses, a reconstrução estava estável, sem defeitos de contorno, a mão apresentava amplitude de movimento completa e o paciente não apresentava problemas nas atividades diárias. Conclusões: A matriz dérmica acelular parece ser uma opção útil na cobertura de defeitos complexos no antebraço, permitindo menor morbidade e rápida recuperação funcional.

Introduction: Giant plexiform neurinoma is a neuroectoderm and inherited disease. It is an uncommon skin tumor associated with NF1, characterized as a benign peripheral nerve sheath tumor surrounding multiple nervous fascicles. The goals of forearm coverage reconstruction are to protect the structures running to the wrist and hand and prevent scarring that leads to movement loss. Both forearm and hand play functional and social roles. Successful management of complex wounds is necessary for the overall functional rehabilitation of these patients. Case Report: A 31-year-old woman presented at the plastic surgery division with a giant plexiform neurofibroma in the right forearm. After careful resection, all anterior forearm tendons were exposed. The defect was covered with graftable Pelnac T (thickness of 3mm and sizing 12 X 24cm2), fixed with 4-0 monocryl sutures. After 10 days, the acellular dermal matrix silicone layer was removed, and a split-thickness skin meshed graft was placed. On day 7, the acellular dermal matrix showed good signs of intake. On day 17, we observed a 95% graft survival. At the 3-month follow-up, reconstruction was stable without contouring defects, the hand had full range of motion, and the patient had no problems in daily activities. Conclusions: Acellular dermal matrix appears to be a useful option in covering complex defects in the forearm, allowing for less morbidity and rapid functional recovery.
