Análisis costo-efectividad del tratamiento con terapia compresiva en la cicatrización de úlceras venosas / Cost-effectiveness analysis of the treatment with compressive therapy in the healing of venous ulcers / Análise de custo-efetividade do tratamento com terapia compressiva na cicatrização de úlceras venosas

Objetivo: analizar el costo-efectividad y calcular la relación costoefectividad incremental del tratamiento multicapa compresivo con respecto al inelástico (bota de Unna y estiramiento corto) según la literatura actual. Método: estudio cuantitativo de costo-efectividad a través de un modelo con ayuda del software TreeAge® para la elaboración del árbol de decisión. Los supuestos anunciados se obtuvieron mediante el uso de datos secundarios de la literatura para estimar el costo y la efectividad de los parámetros asumidos. Para ello, se realizó una revisión sistemática de la literatura con metaanálisis. Resultados: el árbol de decisión, después del Roll Back, mostró que la terapia multicapa prevaleció sobre las alternativas en el caso base, presentó un costo intermedio por aplicación, pero obtuvo la mayor efectividad. El gráfico del análisis de costo-efectividad también demostró que había un dominio extendido de la bota de Unna sobre el vendaje de estiramiento corto. El análisis de sensibilidad reveló que el vendaje multicapa sigue siendo la alternativa con mayor costoefectividad, dentro del umbral de disposición a pagar. Conclusión: la alternativa con mayor costo-efectividad fue el vendaje multicapa, considerado estándar de oro en la literatura. La segunda alternativa con mayor costo-efectividad fue la bota de Unna, la terapia más utilizada en Brasil.

Objective: to analyze the cost-effectiveness and calculate the incremental cost-effectiveness ratio of multilayer compressive treatment in relation to inelastic (Unna boot and short stretch) therapy according to the current literature. Method: quantitative study about cost-effectiveness through modeling with the aid of TreeAge® software for construction of the decision tree. The anticipated assumptions were obtained by using secondary literature data to estimate the cost and effectiveness of the assumed parameters. A systematic literature review with meta-analysis was performed for this end. Results: the decision tree after Roll Back showed that the multilayer therapy dominated the alternatives in the base case, representing an intermediate cost per application, although with the highest effectiveness. The cost-effectiveness analysis graph also showed extended dominance of the Unna boot in relation to the short stretch bandage. The sensitivity analysis showed that multilayer bandage remains a more cost-effective alternative, within the threshold of willingness to pay. Conclusion: the most cost-effective alternative was multilayer bandage, considered the gold standard in the literature. The second most cost-effective alternative was the Unna boot, the most used therapy in Brazil.

Os pressupostos anunciados foram obtidos pelo uso de dados secundários de literatura para estimativa do custo e efetividade dos parâmetros assumidos. Para tal, foi realizada uma revisão sistemática de literatura com metanálise. Resultados: a árvore de decisão, após Roll Back mostrou que a terapia multicamadas dominou as alternativas no caso-base, representando custo intermediário por aplicação, porém, com a maior efetividade. O gráfico da análise de custo-efetividade também mostrou uma dominância estendida da bota de Unna em relação à bandagem de curto estiramento. A análise de sensibilidade mostrou que a bandagem multicamadas permanece como alternativa mais custo-efetiva, dentro do limiar de disposição para pagar. Conclusão: a alternativa com maior custo-efetividade foi a bandagem multicamadas, considerada padrão ouro na literatura. A segunda alternativa mais custo-efetiva foi a bota de Unna, terapia mais utilizada no Brasil.

Electromyographic analysis of suprahyoid musculature before and after therapy taping in young women

ABSTRACT Purpose: to compare the effects of a tongue coupling program with and without therapy taping on suprahyoid muscles in young women. Methods: participants were 14 women aged 19 to 25 years, allocated into two groups. The Experimental Group did 15-second tongue coupling in combination with tape use without tension, while the Control Group only did tongue coupling. Electromyography was used to analyze the suprahyoid muscles before, during, and after training, at rest, in maximum voluntary contraction, and in swallowing. The domains of amplitude and frequency of the electromyography signal were considered, in situations before, after and during the intervention, after which, the therapy taping appreciation questionnaire was administered. The chi-square test was used for clinical variables, Student's t-test, Wilcoxon test, and Mann-Whitney U test were used to compare before and after the intervention, and the Friedman ANOVA test was used for the training. The significance level was set at 5%. Results: no statistically significant differences were found in muscle activity when comparing values before and after the intervention at rest and in swallowing in either group or between them. However, there was a general increase in maximum voluntary contraction in both regions, in both groups. There were positive impressions regarding tape use. Conclusion: this approach in this population did not interfere with muscle activity, although there were positive qualitative results regarding the perception of the stimulated area.

Treatment of experimentally induced partial-thickness burns in rats with different silver-impregnated dressings

Purpose: To evaluate the morphometric, macroscopic and microscopic aspects of experimentally induced partial-thickness burns in rats treated with different silver-based dressings. Methods: Wistar rats were used, divided into six treatments: saline (NaCl 0.9%); silver sulfadiazine 1%; Silvercel; Mepilex Ag; Aquacel Ag and Acticoat. The animals were monitored daily and euthanized at 7, 14 and 30 days after injury induction (DAI). Results: At 7 DAI, necrosis/crust was greater in control, silver sulfadiazine and Mepilex Ag treatments, granulation tissue was induced by Aquacel Ag, polymorphonuclear infiltrate (PMN) infiltration was intensified by Mepilex Ag; mononuclear infiltrate (MN) infiltration and angiogenesis were increased by Silvercel. At 14 DAI, hemorrhage was decreased by Silvercel and Mepilex Ag, PMN infiltration increased by Acticoat. At 30 DAI, angiogenesis was greater in the Acticoat treatment and fibroblasts were increased by Acticoat and Mepilex Ag. Collagen was induced at 14 DAI by silver sulfadiazine and Aquacel Ag and, at 30 DAI, by silver sulfadiazine and Silvercel treatments. Conclusions: Silvercel and Acticoat presented better results than the other products. However, all the dressings were better than the control at some point during the process, and may contribute to the healing of partial thickness burns. Silvercel and Aquacel Ag treatments induced better cosmetic outcomes regarding wound closure and scarring.

Abordaje interdisciplinario de una persona con una úlcera venosa: Reporte de un caso clínico / Interdisciplinary approach of a person with a venous ulcer: Report of a clinical case

Las úlceras venosas son lesiones de piel de alta recurrencia localizadas en los miembros inferiores relacionadas con patologías venosas y con escasa tendencia a la cicatrización espontánea y alta probabilidad de reincidencia. Con el objetivo de visualizar la importancia que tiene para la persona usuaria el abordaje integral derivado del trabajo interdisciplinario de enfermería y terapia física en el manejo de lesiones venosas, se presenta el caso de una paciente de 85 años la cual fue abordada de manera interdisciplinaria en 4 sesiones durante cinco semanas, donde se realizó curación de la lesión y aplicación de terapia compresiva en conjunto con drenaje linfático manual, compresión neumática intermitente y prescripción de plan de ejercicios domiciliares. Adicionalmente, se realizaron sesiones de ejercicios presenciales 2 veces a la semana durante las mismas 5 semanas supervisadas por el profesional de terapia física, que favoreció la resolución de la lesión, mejorando así la calidad de vida de la usuaria.

Venous ulcers are highly recurrent skin lesions located in the lower limbs related to venous pathologies and with little tendency to spontaneous healing and high probability of recurrence. In order to visualize the importance for the user of the comprehensive approach derived from the interdisciplinary work of nursing and physical therapy in the management of venous leg ulcers, the case of an 85-year-old patient is presented who was approached by an interdisciplinary team of physical therapy and nursing in 4 sessions during five weeks, where the venous ulcer was healed and compression therapy was applied in conjunction with manual lymphatic drainage, compression intermittent pneumatics and prescription of home exercise plan. Additionally, face-to-face exercise sessions were carried out 2 times a week during the same 5 weeks, supervised by the physical therapy professional, which favored the resolution of the venous ulcer, thus improving the quality of life of the user. The interdisciplinary approach is highlighted as a central aspect in the evolution of the case.

Polymeric Material With Controlled Release of Antimicrobial Agents for Medical Application

@#Introduction: Nowadays the use of synthetic polymers has become an integral part of modern medicine. Poly(2-hydroxyethyl methacrylate) has attracted special attention for therapeutic use. The objective of this study was to develop novel polymeric material based on poly(2-hydroxyethyl methacrylate) by addition of water as pore-forming agent and antimicrobial components, which would differ from similar materials by controlled release of active substances. Methods: The antimicrobial release kinetics study materials were immersed into distilled water followed by sampling and measuring their concentration. Concentration of chlorhexidine bigluconate and metronidazole was determined using spectrophotometric method and decamethoxine by photocolorimetric method based on reaction with eosin. The swelling rate was determined by gravimetric method. Results: Conventional dressing materials, after being soaked with antiseptic solutions, have demonstrated limited abilities in releasing active substances. Gauze pads were found to release antimicrobials during a short period of time reaching 50–80 % for decamethoxine containing samples and almost 100 % for those with metronidazole and chlorhexidine bigluconate at 2 h of observation. No study active substances were released from activated charcoal dressings. Similar results were obtained with porcine xenografts. Unlike the above mentioned dressing materials, modified polymer matrix based on poly(2-hydroxyethyl methacrylate) showed the controlled release of antimicrobial substances into water medium. Study material containing 3.0 % of decamethoxine and 76.3 % of water demonstrated optimal efficiency in the rate and duration of release, exerting high physical and mechanical properties. Conclusion: The synthesized polymers are similar to conventional dressings in antimicrobial release kinetics, but in some characteristics they are better for practical application.

Objective:To evaluate clinical efficacy and safety of calcium-based antimicrobial peptide compounds cooling gel (CAPCS cooling gel) in the treatment of atopic dermatitis (AD) .Methods:A randomized, double-blind, active-controlled clinical study was conducted. From July 2019 to May 2020, 80 adult patients with mild-to-moderate AD were enrolled from Beijing Friendship Hospital, Capital Medical University, and randomly and equally divided into 2 groups: test group topically treated with CAPCS cooling gel, control group topically treated with hydrocortisone cream, and the treatment was performed thrice a day for 4 consecutive weeks. Before, 1, 2 and 4 weeks after the start of treatment, efficacy was evaluated according to the Eczema Area and Severity Index (EASI), Visual Analog Scale (VAS), and Investigator′s Global Assessment (IGA) scores, and adverse events were recorded. Efficacy and safety were compared by using repeated measures analysis of variance and chi-square test.Results:Of the 80 patients with AD, 43 were males and 37 were females, and the age was 52.71 ± 16.71 years. Before the treatment, there was no significant difference in gender, age, EASI, VAS or IGA scores between the two groups (all P > 0.05). After 1- and 2-week treatment, there was no significant difference in the response rate between the test group (10.00% [4/40], 57.50% [23/40], respectively) and control group (15.00% [6/40], 52.50% [21/40] respectively, both P > 0.05). After 4-week treatment, the response rate was significantly higher in the test group (82.50%, 33/40) than in the control group (57.50%, 23/40, P < 0.05). Compared with the control group, the test group showed significantly decreased VAS scores after 1-, 2- and 4-week treatment ( U = 1253.00, 1121.00, 1091.50, respectively, all P < 0.05). No drug-related adverse events were observed in either of the groups. Conclusion:CAPCS cooling gel is safe and effective in the treatment of mild-to-moderate AD in adults, and can be applied in clinic.

Lipoaspiração abdominal: evoluindo de alta para média definição / Abdominal liposuction: evolving from high to medium definition

Introdução: Atualmente, o conceito de lipoaspiração de alta definição (LAD ou Lipo HD), tem aceitação cada vez maior. Porém, percebemos a busca de pacientes por resultados com marcação não tão vigorosa, especialmente na região abdominal, o que temos chamado de lipoaspiração de média definição ou Lipo MD. O objetivo deste estudo é apresentar uma série de casos clínicos realizados pela técnica de Lipo MD, utilizando método convencional de lipoaspiração. Métodos: Estudo retrospectivo onde os pacientes foram submetidos à lipoaspiração para obter a definição abdominal, sob as linhas alba, semilunar e interseções tendíneas. Utilizamos no curativo, tubos de silicone cilíndricos e maleáveis. Resultados: Foram inclusos 107 casos, dos quais 85 completaram o seguimento de 6 meses. Após 6 meses, os resultados foram considerados bons por todos os pacientes e equipe médica. Discussão: O conceito de Lipo HD é recente e vem recebendo aceitação crescente. A busca por resultados mais naturais e suaves, levou ao desenvolvimento do termo lipoaspiração de média ou moderada definição (Lipo MD). Acreditamos que todo cirurgião plástico pode realizar este acabamento adicional de definição abdominal, com seu método de preferência de lipoaspiração, seja de baixa energia (seringa, aspirador e vibrolipoaspirador), ou alta energia (laserlipoaspiração ou lipoultrassônica), podendo utilizar tubos de silicone para maior aderência da pele à aponeurose e melhor definir os sulcos formados. Conclusão: Foi descrito técnica de lipoaspiração abdominal de média definição (Lipo MD), utilizando método convencional de lipoaspiração, nas linhas alba e semilunar, bem como das interseções tendíneas do músculo reto abdominal.

Introduction: Currently, the concept of high-definition liposuction (HDL or HD Lipo) is increasingly accepted. However, we noticed patients' search for results with not-sovigorous marking, especially in the abdominal region, what we have called medium-definition liposuction or MD Lipo. This study aims to present a series of clinical cases performed by the MD Lipo technique, using the conventional liposuction method. Methods: Retrospective study where patients underwent liposuction to obtain abdominal definition under the linea alba, semilunaris and tendinous intersections. We use cylindrical and malleable silicone tubes in the dressing. Results: One hundred and seven cases were included, of which 85 completed the 6-month follow-up. After 6 months, the results were considered good by all patients and medical staff. Discussion: The concept of HD Lipo is recent and has been receiving increasing acceptance. The search for more natural and smooth results led to developing the term medium or moderate definition liposuction (MD Lipo). We believe that every plastic surgeon can perform this additional abdominal definition finish with his preferred method of liposuction, either low energy (syringe, liposuction device and vibroliposuction device) or high energy (laser liposuction or ultrasonic liposuction). We can use silicone tubes to better adherence of the skin to aponeurosis and better define the grooves formed. Conclusion: The technique of medium definition abdominal liposuction (MD Lipo) has been described, using the conventional method of liposuction, in the alba and semilunaris lines and the tendinous intersections of the rectus abdominis muscle.

Curativo na ferida operatória para prevenção da infecção de sítio cirúrgico em pacientes adultos oncológicos: revisão sistemática / Surgical wound dressing to prevent surgical site infection in adult oncological patients: a systematic review

Introdução: O manejo da ferida operatória limpa no pós-operatório é uma importante intervenção para prevenção da infecção do sítio cirúrgico. O uso de curativo estéril na ferida operatória, aproximada por primeira intenção, deve ser utilizado de forma asséptica e tem como principal objetivo impedir a contaminação por microrganismo. No entanto, para as diretrizes clínicas para prevenção de infecção do sítio cirúrgico, não existe consenso sobre a escolha do curativo ideal. Objetivo: Sintetizar as evidências sobre o curativo efetivo para prevenção da infecção de sítio cirúrgico aplicado na ferida operatória, aproximada por primeira intenção, em pacientes oncológicos adultos submetidos a cirurgia eletiva. Materiais e Método: Trata-se de uma revisão sistemática pautada no Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), registrada sob o número CRD42020156908, constituída das etapas: 1) Elaboração e registro do protocolo da revisão; 2) Delimitação da pergunta da revisão; 3) Definição dos critérios de elegibilidade; 4) Busca e seleção dos estudos; 5) Coleta de dados; e 6) Síntese e apresentação dos resultados da revisão sistemática. A estratégia de busca foi realizada nas bases de dados: Cochrane Central, Cinahl, Embase, Lilacs, Livivo, PubMed, Scopus e Web of Science. A estratégia de busca foi fundamentada no objetivo da revisão e adaptada para cada base de dados consultada. Utilizaram-se descritores controlados e palavras-chave, a saber: Neoplasms AND Bandages AND Surgical Wound Infection AND prevention and control. A literatura cinzenta consultada foi o Google Acadêmico e a ProQuest Dissertations and Theses Database. As etapas foram realizadas de forma independente e mascarada por dois revisores, e um terceiro para resolução de conflitos. Ao término da seleção dos estudos primários, realizou-se a busca manual nas listas de referências dos estudos primários incluídos. Resultados: A amostra compôs-se de sete ensaios clínicos aleatorizados. Os curativos absorventes foram comparados em cinco estudos incluídos. A mupirocina foi avaliada em dois estudos. Os curativos com prata foram avaliados em três estudos. O mel, a parafina, o tempo de retirada do curativo e a terapia por pressão negativa aparecem em um único ensaio cada. Em relação ao risco de viés, foram avaliados os sete estudos incluídos pela ferramenta da Cochrane Risk of Bias (RoB 2), sendo seis de baixo risco e um estudo avaliado como risco incerto. A metanálise foi realizada com três ensaios que testaram curativo de prata versus o curativo absorvente, não demonstrando diferenças estatisticamente significantes (p= 0.77) na prevenção da infecção do sítio cirúrgico. O Intervalo de Confiança (IC) do diamante metanalítico varia de 0,41 a 1,06, assim não demonstra diferença estatisticamente significante na efetividade entre os tipos de curativo. A certeza da evidência foi avaliada pelo sistema GRADE e foi considerada forte em todos os domínios. Conclusões: A ausência de padronização em relação ao tipo e tempo de curativo utilizados nos estudos pode ser um dificultador para as recomendações do curativo ideal. E apesar dos resultados promissores com curativo impregnado com prata, ainda não é possível concluir qual é o curativo mais efetivo aplicado na ferida operatória, para prevenção de infecção de sítio cirúrgico, com fechamento primário, em pacientes oncológicos adultos submetidos a cirurgia eletiva

Introduction: The management of clean surgical wounds in the postoperative period is an important intervention to prevent surgical site infections. The use of sterile dressings in operative wounds, held together by primary intention, should be used aseptically, with the main objective of preventing microbiological contamination. However, clinical guidelines for the prevention of surgical site infection do not provide a consensus about the choice of the optimal dressing. Objective: The aim of this review was to summarize the existing evidence about effective surgical site dressings for the prevention of operative wound infections, held together by primary intention in adult oncological patients submitted to elective surgery. Materials and Method: This was a systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), registered under number CRD42020156908. It was developed according to the following phases: 1) preparing and registering the review protocol; 2) defining the review question; 3) defining the eligibility criteria; 4) searching and selecting the studies; 5) data collection; and 6) summarizing and presenting the results of the systematic review. The search strategy was carried out in the following databases: Cochrane Central, Cinahl, Embase, Lilacs, Livivo, PubMed, Scopus, and Web of Science. The search strategy was based on the objective of the review and adapted for each of the consulted databases. Controlled descriptors and keywords were used, namely: Neoplasms AND Bandages AND Surgical Wound Infection AND prevention and control. The grey literature consulted was Google Scholar, ProQuest Dissertations and Theses Database. The stages were carried out independently and blindly by two reviewers, while a third reviewer was used to settle any conflicts. After selecting the primary studies, the researchers manually searched the reference lists of the included primary studies. Results: The sample consisted of seven randomized clinical trials. Absorbent dressings were compared in five included studies. Mupirocin was evaluated in two studies. Silver dressings were evaluated in three studies. Honey, paraffin, dressing removal time, and negative pressure therapy all appeared in a single trial each. Regarding the risk of bias, the seven studies were assessed using the Cochrane Risk of Bias tool (RoB 2); six presented a low risk of bias and one study presented uncertain risk. The meta-analysis was performed with three trials that tested silver dressings versus absorbent dressings, with no statistically significant differences (p= 0.77) in the prevention of surgical site infection. The confidence interval (CI) of the diamond ratio varied between 0.41 and 1.06, thus it did not demonstrate a statistically significant difference in effectiveness between the types of dressing. Certainty of the evidence was evaluated using the GRADE system, which considered it strong in all categories. Conclusions: The lack of standardization regarding the type and duration of dressing used in the studies can make it difficult to recommend the ideal dressing. And despite the promising results with dressings impregnated with silver, it is still not possible to conclude which is the most effective dressing applied to the surgical wound, to prevent surgical site infection, with primary closure, in adult cancer patients undergoing elective surgery

Efetividade da drenagem linfática manual associada a bandagem funcional na melhora clínica do fibro edema gelóide em gestantes: ensaio clínico, controlado e randomizado / Effectiveness of manual lymphatic drainage associated with functional banding in the clinical improvement of gynoid lipodystrophy in pregnant women: a clinical, controlled and randomized trial

No período gestacional, mulheres podem desencadear disfunções hormonais que induzem ao acúmulo de edema e nódulos fibróticos, favorecendo a formação de relevos cutâneos ocasionando sensação dolorosa. Sendo assim, este estudo visou comparar a efetividade da drenagem linfática manual com ou sem o uso da bandagem funcional no fibro edema gelóide (FEG) em gestantes no segundo e terceiro trimestre gestacional. Trata-se de um ensaio clínico randomizado, composta por três grupos: G1: Drenagem Linfática Manual (DLM); G2: DLM + Bandagem Funcional (BF); G3: Grupo Controle. Critério de inclusão: gestantes no segundo e terceiro trimestre, primípara e multípara e gestação de feto único. Realizou-se a DLM na região dos glúteos e membros inferiores e a BF aplicada da região inguinal em forma de teia direcionada a região medial dos glúteos, usando uma tensão superficial de 10%. Utilizou-se um protocolo de avaliação do fibro edema gelóide (PAPEG), anamnese, exame físico com inspeção, teste de preensão, teste de sensibilidade tátil (monofilamento de semmes ­ weinstein), avaliação da sensibilidade, grau, dor, recomendação e satisfação da paciente. Foram realizadas fotos da região do glúteo do antes e depois e avaliadas por 10 especialistas através da fotogrametria. Observou-se uma melhora clínica significativa no grupo drenagem e na associação com a bandagem quando comparado ao grupo controle pelos 10 especialistas. Houve uma melhora significativa nas notas dos especialistas nos grupos G1 e G2, quando comparado ao G3. Portanto, o presente estudo demonstrou uma melhora clínica no fibro edema gelóide das gestantes que receberam a DLM isolada, e na associação com a BF, quando comparado ao grupo controle.

During pregnancy, women can trigger hormonal dysfunctions that induce the accumulation of edema and fibrotic nodules, favoring the formation of rifted skin causing a painful sensation. Therefore, this study aimed to compare the effectiveness of manual lymphatic drainage with or without the use of functional bandages in gynoid lipodystrophy (GLD) in pregnant women in the second and third trimester. This was a randomized clinical trial, composed of three groups: G1: Manual Lymphatic Drainage (MLD); G2: MLD + Functional Bandage (FB); G3: Control Group. Inclusion criteria: pregnant women in the second and third trimester, primiparous or multiparous and a single fetus pregnancy. MLD was performed in the gluteal region and lower limbs, and FB was applied from the inguinal region in the form of a web directed to the medial gluteal region, using a surface tension of 10%. An evaluation protocol for gynoid lipodystrophy (EPGLD) with anamnesis, a physical examination with an inspection, a grip test, tactile sensitivity test (Semmes-Weinstein monofilament test), assessing the patient's sensitivity, grade, pain, recommendation, and satisfaction was used. Photos were taken of the gluteus region before and after and were then evaluated by 10 specialists through photogrammetry. There was a significant clinical improvement in the drainage group and in the association with the bandage when compared to the control group by the 10 specialists. There was a significant improvement in the scores of specialists in groups G1 and G2, when compared to G3. Therefore, the present study demonstrated a clinical improvement in gynoid lipodystrophy of pregnant women who received MLD alone, and in association with FB, when compared to the control group.

Objective:To evaluate short-term clinical efficacy and safety of a cooling gel containing calcium-based antimicrobial peptide compounds (CAPCS cooling gel) combined with desonide cream in the treatment of atopic dermatitis (AD) in children.Methods:From November 2019 to September 2020, a randomized, double-blind controlled clinical trial was conducted in 60 children with AD enrolled from Department of Dermatology and Venereology, West China Hospital, Sichuan University. The 60 patients were randomly and equally divided into 2 groups: test group treated with topical desonide cream in the morning and evening as well as topical CAPCS cooling gel at noon during the first 3 days of treatment, followed by topical CAPCS cooling gel in the morning, at midday and in the evening for 11 days; control group treated with topical desonide cream in the morning and evening as well as topical CAPCS-free placebo gel at noon during the first 3 days of treatment, followed by topical CAPCS-free placebo gel in the morning, at midday and in the evening for 11 days. The treatment lasted 2 weeks. Finally, 56 AD patients completed the follow-up, and 28 in each group were included into the following analysis. Clinical indices, such as eczema area and severity index (EASI) , visual analogue scale (VAS) , investigator′s global assessment (IGA) and dermatology life quality index (DLQI) , were recorded before, 7 ± 3 days and 14 ± 3 days after the treatment, so were adverse reactions.Results:After 1-week treatment, 1 patient in the test group and 1 in the control group showed response to the treatment, with the response rate being 3.57% in both groups; after 2-week treatment, 12 patients in the test group and 2 in the control group showed response to the treatment, with response rates being 42.86% and 7.14% respectively; there were significant differences in the treatment outcomes between the two groups after 1- and 2-week treatment ( Z = -4.318, -5.474, respectively, both P < 0.05) . There was no significant difference in the EASI, VAS, IGA or DLQI score between the two groups before treatment (all P > 0.05) ; nonparametric Friedman test showed a significant difference in the changing trend of the EASI score over time between the two groups ( χ2 = 45.720, P < 0.05) . Two-way repeated measurement analysis of variance showed a significant difference in the VAS score ( F = 10.738, P = 0.002) , but no significant difference in IGA or DLQI score between the test group and control group after 1-week treatment ( F = 0.066, 0.804, P = 0.135, 0.374, respectively) ; after 2-week treatment, there were significant differences in the VAS, IGA and DLQI score between the 2 groups ( F = 67.313, 38.949, 51.503, respectively, all P < 0.001) . During the clinical study period, 1 adverse event occurred in the test group and control group each, which manifested as tingling or irritating sensation at the topically treated sites, and there was no significant difference in the incidence rate of adverse events between the two groups ( P > 0.05) . Conclusion:Short-term topical application of CAPCS cooling gel combined with desonide cream is effective for the treatment of AD in children, and does not increase the incidence of adverse reactions compared with the placebo.

Terapias aplicadas no tratamento das lesões por queimaduras de terceiro grau e extensão variável: revisão integrativa / Therapies applied in the treatment of injuries by burns of third degreeand variable extension: an integrative review

RESUMO: Lesões por queimaduras se apresentam como simples ou graves de acordo com sua profundidade, extensão e localização. Diversas terapias são lançadas no mercado, devendo prover um ambiente úmido, amplo aspecto antimicrobiano e serem efetivas, mesmo na presença de grande quantidade de exsudato, visando os benefícios que trarão para o processo de cicatrização. Neste sentido, este estudo objetivou revisar a literatura acerca da caracterização clínica e terapias aplicadas no tratamento das queimaduras de terceiro grau e de extensão variável. Para alcançar o objetivo proposto, foi realizada uma revisão integrativa da literatura nas bases de dados LILACS, BDENF e SciELO. Foram selecionados 17 artigos e os resultados apontaram que os curativos a base de prata são os mais utilizados, dentre eles, sulfadiazina de prata, prata nanocristalina e espuma absorvente. Para casos particulares mais complexos, a matriz de regeneração dérmica assume-se como uma alternativa eficaz e segura. A utilização da terapia por pressão negativa no tratamento da contratura cicatricial, muito presente nas lesões de terceiro grau, agrega como vantagem o fato de o paciente não precisar ficar imobilizado e imóvel após as cirurgias. Dentre as terapias inovadoras no tratamento de queimaduras, evidenciou-se o uso de enxerto da pele de tilápia, que foi citado por um estudo como um possível subproduto com alta aplicabilidade clínica. Ao longo do estudo foi possível concluir que os pacientes necessitam de uma assistência adequada desde os cuidados imediatos até o fim da reabilitação. Com o passar dos anos, inovações terapêuticas vêm sendo estudadas para serem implantadas no tratamento ao paciente queimado, entre elas a substituição de pele vem ganhando espaço pelos resultados positivos.

ABSTRACT: Burn injuries are classified as simple or severe according to their depth, extent, and location. Several therapies are commercially available, which should provide a humid skin, broad antimicrobial aspect and be effective, even if a large amount of exudate is present, aiming at benefiting the healing process. Therefore, this study aimed to review the literature on the clinical characterization and therapies applied in the treatment of third-degree burns and of variable extension. To reach the proposed objective, an integrative literature review was carried out in the LILACS, BDENF, and SciELO databases. Seventeen papers were selected, and the results showed that silver-based dressings are the most used, and among these, stand out: silver sulfadiazine, nanocrystalline silver, and an absorbent foam. For more complex cases, the dermal regeneration matrix is an effective and safe alternative. The use of negative pressure therapy in the treatment of scar contracture, present in third-degree injuries, has some advantage since the patient does not need to be immobilized and still after the surgeries. Among the innovative therapies in the treatment of burns, the use of tilapia skin graft was evidenced, which was mentioned by a study as a possible by-product with high clinical applicability. Throughout the study, it was possible to conclude that patients need adequate assistance, from immediate care, until the end of the rehabilitation. Over the years, therapeutic innovations have been studied to be implemented in the treatment of burned patients, including the replacement of skin, which has been highlighted due to the positive results.

Resultados: Se determinó que en las instituciones de salud pública son atendidos un promedio 17 pacientes mensualmente (60% provenientes de hospitalización y 40% de consultorio externo). Equivale decir que 11,016 pacientes presentan heridas crónicas de difícil resolución al año, los cuales requerirán de tratamiento especializado y una demanda anual promedio de 110,160 apósitos en stock. Los apósitos con mayor demanda corresponden a los Hidrogeles e Hidrocoloides, respectivamente que son utilizados por los resultados positivos que ofrecen en la curación de las heridas, aunque en ocasiones la limitante es el aspecto económico. En el mercado, el precio unitario oscila entre los 20 y 90 soles, esto representa una inversión económica de 1500 soles en promedio por paciente, produciendo en algunos casos complicaciones o abandono del tratamiento cuando los recursos son escasos. Conclusiones: La demanda de pacientes con heridas crónicas de difícil resolución en las instituciones de salud públicas de Lima metropolitana es alta. Es importante promover e incentivar la investigación de nuevas alternativas terapéuticas y/o dispositivos biomédicos que favorezcan su curación.

Objective: To analyze the potential for innovation in dressings to treat chronic wounds in the City of Lima. Methods: A qualitative study was carried out by means of interviews to medical experts and purchasing managers of medical supplies for the treatment of difficult-to-resolve wounds in 8 representative public health institutions with categories 1-4 within the only 54 of Lima, Peru - 2018. Results: It was determined that an average of 17 patients is treated in public health institutions on a monthly basis (60% from hospitalization and 40% from an outpatient office). It is equivalent to say that 11,016 patients present chronic wounds of difficult resolution each year, which will require specialized treatment and an average annual demand of 110,160 dressings in stock. The dressings with the highest demand correspond to the Hydrogels and Hydrocolloids, respectively; used because of the positive results they offer in wound healing, despite economic limitations. The market price per unit ranges between 20 and 90 soles (S/.), representing an economic investment of 1500 soles on average per patient, in some cases causing complications or abandonment of treatment when resources are scarce. Conclusions: There is a high demand for patients with chronic wounds of difficult resolution in the public health institutions of Lima. It is important to promote and incentivize the investigation of new therapeutic alternatives and / or biomedical devices that favor its treatment.

Kinesio Taping® as an innovative therapeutic tool to prevent nasal septal lesions in newborns: a case study / Kinesio Taping® como uma ferramenta terapêutica inovadora para prevenir lesões do septo nasal em recém-nascidos: um estudo de caso

Abstract Introduction: The immaturity of the integumentary system in premature newborns (PTNB), associated with ventilatory support, contributes to the higher occurrence of nasal trauma. Objective: This article reports on the case of a newborn submitted to Kinesio® Taping as an innovative prophylactic therapy for nasal trauma. Method: We report on Kinesio® Taping, a material frequently used to treat pain in athletes, as an innovative therapeutic tool to prevent nasal septal lesions in a PTNB undergoing noninvasive mechanical ventilation (NIMV), who, after 13 days on NIMV, presented with nasal septal lesions. Results: The Kinesio® Taping, was positioned to protect the nasal septum from friction caused by direct contact of the nasal prong, maintained NIMV pressure, adapted well to the shape of the nose and improved nasal trauma after 3 days of use. Conclusion: Given that breathing in this period of life occurs predominantly through the nose and maintaining the integrity of this mucosa reduces not only respiratory discomfort, but also deformities and the risk of infections. The present study presents KT as an innovative protective tool against nasal injury in premature newborns submitted to positive pressure ventilation using nasal prongs. Despite describing a single case, the results obtained were promising. However, studies with a larger sample and different groups are needed, primarily to compare with existing methods.

Resumo Introdução: A imaturidade do sistema tegumentar em recém-nascidos prematuros (RNPT), associado a necessidade de suporte ventilatório contribuem para uma maior ocorrência de traumas nasais. Objetivo: Este artigo relata o caso de um recém-nascido submetido ao Kinesio® Taping, como terapia profilática inovadora para trauma nasal. Método: Relatamos o uso do Kinesio® Taping, material frequentemente usado para tratamento de dor em atletas, como uma ferramenta de inovação terapêutica para prevenção de lesões do septo nasal em um RNPT em ventilação mecânica não invasiva (VMNI) que após 13 dias em VMNI apresentou lesão nasal e septal. Resultados: O Kinesio® Taping, foi posicionado de forma a proteger a columela e o septo nasal do atrito provocado pelo contato direto da pronga nasal, manteve a pressão da VMNI, boa adaptação ao formato do nariz e melhorou o trauma nasal após 3 dias de uso. Conclusão: Considerando que a respiração nesse período da vida acontece predominantemente pelo nariz, manter a integridade dessa mucosa reduz não só o desconforto respiratório, mas também as deformidades e o riscos de infecções. O presente estudo apresenta o KT como uma ferramenta inovadora de proteção contra lesões nasais em recém-nascidos prematuros submetidos à ventilação com pressão positiva com ponta nasal. Apesar de descrever um único caso, os resultados obtidos foram promissores. No entanto, são necessários estudos com uma amostra maior e grupos diferentes, principalmente para comparar com os métodos existentes.

Pine nanocellulose and bacterial nanocellulose dressings are similar in the treatment of second-degree burn? experimental study in rats / Os curativos de nanocelulose de pinus e nanocelulose bacteriana são semelhantes no tratamento da queimadura de segundo grau? estudo experimental em ratos

ABSTRACT Background: Despite all the advances in medicine and the wide variety of dressings available, the treatment of burn wounds still represents an important medical challenge. The pinus cellulose membrane dressing is a biomaterial with characteristics similar to those of bacterial cellulose, but with lower cost. Aim: To evaluate the efficacy of pinus nanocellulose membrane on healing of deep second degree burns in rats and compare with Membracel®. Method: Thirty male Wistar rats were submitted to deep second degree burn in dorse, with boiling water at 97o C for 20 s, generating a 314 mm² area wound. The animals were distributed in three dressing groups (n=10): group 1 - simple gauze; group 2 - bacterial cellulose membrane (Membracel®); and group 3 - pinus cellulose membrane. They were evaluated for 20 days to verify clinical condition, macro and microscopic appearance and wound contraction. Results: All of them remained clinically well with no differences in weight. Crusts were observed in group 1, and none in groups 2 and 3. Regarding to scar contraction, groups 2 and 3 were similar, better than group 1. Microscopic analysis showed predominance of advanced healing degree in groups 1 and 3, and initial in group 2. Mature collagen was predominant in all groups. Conclusion: The pinus nanocellulose membrane is effective in the treatment of experimental second degree burn in rats and its effectiveness is similar to that of the bacterial nanocellular membrane.

RESUMO Racional: Apesar de todos os avanços da medicina e da grande variedade de curativos disponíveis, o tratamento das queimaduras ainda representa importante desafio médico. O curativo de membrana de celulose de pinus é biomaterial com características semelhantes à de celulose bacteriana, mas de menor custo. Objetivo: Avaliar a eficácia da membrana de nanocelulose de pinus na cicatrização de queimaduras profundas de segundo grau em ratos e comparar com a Membracel®. Método: Trinta ratos Wistar machos foram submetidos à queimadura profunda de segundo grau em dorso, com água fervente a 97o C por 20 s, gerando lesão de 314 mm². Os animais foram distribuídos em três grupos de curativos (n = 10): grupo 1 - gaze simples; grupo 2 - membrana de celulose bacteriana (Membracel®); e grupo 3 - membrana de celulose de pinus. Eles foram avaliados por 20 dias para verificar o quadro clínico, aspecto macro e microscópico e a contração da ferida. Resultados: Todos permaneceram clinicamente bem, sem diferenças de peso. Crostas foram observadas no grupo 1 e nenhuma nos grupos 2 e 3. Em relação à contração da cicatriz, os grupos 2 e 3 foram semelhantes, melhores que o grupo 1. A análise microscópica mostrou predomínio de grau de cicatrização avançado nos grupos 1 e 3, e inicial no grupo 2. O colágeno maduro foi predominante em todos os grupos. Conclusão: A membrana de nanocelulose de pinus é eficaz no tratamento de queimaduras experimentais de segundo grau em ratos e sua eficácia é semelhante à da membrana nanocelular bacteriana.
