ABSTRACT
El propósito de este reporte es describir el tratamiento no quirúrgico y quirúrgico en una paciente con múltiples implantes con peri-implantitis. Inflamación, sangrado espontáneo, supuración y pérdida ósea fueron los signos clínicos y radiográficos observados en los 21 implantes presentes en su boca. Las profundidades al sondaje oscilaban entre 5 y 15 mm. Se llevó a cabo la terapia no quirúrgica asociada a antibióticos sistémicos (Metronidazol 500 mg) y antiséptico (Clorhexidina 0,12%) con la finalidad de reducir los signos de inflamación y sangrado. Durante la re-evaluación se colocaron gránulos de Minociclina de liberación controlada en las bolsas residuales. Los sitios que no respondieron fueron abordados quirúrgicamente, realizando además la implantoplastia de las espiras que quedaron expuestas al medio bucal. Uno de los implantes debió ser explantado. A los 9 meses, no presentaba signos de inflamación peri-implantar, sangrado al sondaje ni pérdida ósea progresiva.
The aim of this report is to describe the non-surgical and surgical treatment of a patient with multiple implants with peri-implantitis. Inflammation, spontaneous bleeding, suppuration and bone loss were the clinical and radiographic signs observed in the 21 implants present in her mouth. Probing depths ranged from 5 to 15 mm. Non-surgical therapy with systemic antibiotics (Metronidazole 500 mg) and antiseptic (Chlorhexidine 0.12%) was carried out in order to reduce the signs of inflammation and bleeding. During re-evaluation, controlled-release minocycline granules were placed in the residual pockets. The sites that did not respond were approached surgically. Also, the implantoplasty of the threads that were exposed to the oral environment was performed. One of the implants had to be explanted. At 9 months, there were no signs of peri-implant inflammation, bleeding on probing or progressive bone loss.

Abstract The diagnosis of genital ulcers remains a challenge in clinical practice. Lipschütz ulcer is a non-sexually transmitted rare and, probably, underdiagnosed condition, characterized by the sudden onset of vulvar edema along with painful necrotic ulcerations. Despite its unknown incidence, this seems to be an uncommon entity, with sparse cases reported in the literature. We report the case of an 11-year-old girl who presented at the emergency department with vulvar ulcers. She denied any sexual intercourse. The investigation excluded sexually transmitted infections, so, knowledge of different etiologies of non-venereal ulcers became essential. The differential diagnoses are extensive and include inflammatory processes, drug reactions, trauma, and malignant tumors. Lipschütz ulcer is a diagnosis of exclusion. With the presentation of this case report, the authors aim to describe the etiology, clinical course, and outcomes of this rare disease, to allow differential diagnosis of genital ulceration.

This survey evaluated mombin leaves (Spondias mombin L.) decoction efficiency as an antiseptic during post-surgery period on cats submitted to orchiectomy and ovariosalpingohisterectomy. For this purpose, 45 castrated mongrels cats were divided into three groups, the first group as a positive control using 0.5% chlorhexidine-alcohol solution, the second a negative control group using sterile distilled water and, finally, the test group using mombin leaves decocted with a concentration of 100 mg/mL. All animals, independent of age and sex, had visibly healed in most cases in a similar time. Animals treated with mombin leaves decoction presented a significant reduction of bacterial growth. In addition, the animals treated in the test group had better surgical wound healing. All isolated bacterial strains presented inhibition halo for chlorhexidine and for Spondias mombin L. Thus, the decoction of Spondias mombin L. leaves proved antiseptic efficacy in the surgical wounds of cats submitted to orchiectomy and ovariosalpingohisterectomy.(AU)
Foi avaliada a eficiência do decocto das folhas de cajá (Spondias mombin L.) como antisséptico no pós-cirúrgico de gatos submetidos à orquiectomia e ovariosalpingohisterectomia. Para tal, foram submetidos à castração 45 gatos sem raça definida, divididos em três grupos. O primeiro grupo como controle positivo com Solução Alcoólica de Clorexidine a 0,5%; segundo grupo controle negativo com água destilada estéril; e o grupo teste com o decocto de cajá à concentração de 100 mg/mL. Todos os animais, independentemente da idade e sexo, tiveram cicatrização visível em tempo similar. Animais tratados com o decocto apresentaram uma redução significativa do crescimento bacteriano. Além disso, observou-se uma melhor cicatrização das feridas cirúrgicas dos animais tratados no grupo teste. Todas as estirpes bacterianas isoladas apresentaram halo de inibição para clorexidine e para Spondias mombin L. Portanto, o decocto das folhas da Spondias mombin L. apresentou eficácia antisséptica nas feridas cirúrgicas de gatos submetidos à orquiectomia e ovariosalpingohisterectomia.(AU)

Inflatable penile prostheses are an important tool in the treatment of medically refractory erectile dysfunction. One of the major complications associated with these prostheses is infections, which ultimately require device explanation and placement of a new device. Over the past several decades, significant work has been done to reduce infection rates and optimize treatment strategies to reduce patient morbidity. This article reviews the current state of knowledge surrounding penile prosthesis infections, with attention to the evidence for methods to prevent infection and best practices for device reimplantation.

Métodos Estudo observacional e prospectivo, com 25 pacientes com cateter venoso central inserido para realização do transplante de células-tronco hematopoéticas. Diariamente avaliou-se as características do curativo, da pele, clínicas do paciente e relacionadas a infecção. Os pacientes foram acompanhados a partir do primeiro dia da inserção do CVC até a sua remoção, até o limite de 45 dias a partir da data de inserção do CVC. Resultados A infecção da corrente sanguínea relacionada ao cateter ocorreu em 28% dos pacientes, houve associação entre neutropenia febril e infecção (p<0,01). A irritação cutânea foi identificada em 24% dos pacientes. Não foi identificada associação entre infecção da corrente sanguínea relacionada ao cateter e a irritação cutânea (p=0,51). Houve associação significativa entre irritação cutânea e suspensão do uso do curativo (p=0,03). As trocas não programadas ocorreram em 50% das trocas identificadas e o principal motivo foi a presença de sangue no curativo (57,8%). Conclusão O uso do curativo gel de clorexidina em pacientes submetidos ao TCTH demonstrou ser uma medida eficaz na redução da ocorrência de infecções relacionadas ao cateter, quando comparado aos dados da literatura. Os casos de ICSRC encontrados foram associados, principalmente, à condição de neutropenia, muito comum nesta população. Os casos de irritação cutânea relacionados ao curativo identificados e a presença de sangue como principal motivo de troca não programada salientam a importância do conhecimento relacionado ao uso do curativo por parte dos enfermeiros assistenciais, a fim de criar protocolos que indiquem o uso e manejo do curativo com segurança.

Abstract Objective Monitor the use of chlorhexidine gel dressing in the central venous catheter of children and adults submitted to hematopoietic stem cell transplantation (HSCT) to check for catheter-related bloodstream infection and skin irritation while using this dressing. Methods This is a prospective observational study with 25 patients with central venous catheters (CVC) inserted for hematopoietic stem cell transplantation. Dressing characteristics, skin characteristics, clinical conditions of patients and infection-related characteristics were evaluated daily. Patients were monitored from the first day of CVC insertion until removal, up to 45 days from the CVC insertion date. Results Catheter-related bloodstream infection (CRBSI) occurred in 28% of all patients, with an association between febrile neutropenia and infection (p<0.01). Skin irritation was identified in 24% of patients. No association was found between catheter-related bloodstream infection and skin irritation (p=0.51). A significant association was observed between skin irritation and dressing removal (p=0.03). Unscheduled dressing changes corresponded to 50% of all dressing changes identified during the study, and the main reason was presence of blood in the dressing (57.8%). Conclusion Using chlorhexidine gel dressing in patients submitted to HSCT proved to be an effective measure to reduce the occurrence of catheter-related infections, when compared to literature data. The cases of CRBSI found in this study were mainly associated with the condition of neutropenia, which is very common in this population. The cases of dressing-related skin irritation and presence of blood as the main reason for unscheduled change highlight the importance of nurses having proper knowledge about how to use this dressing in order to create protocols for safe dressing use and handling.

Brazil has one of the largest commercial cattle herds in the world, which naturally coexist with an enormous number of parasitic species. Southern cattle tick, Rhipicephalus (Boophilus) microplus, is among these species, interfering with animal productivity and causing losses to the beef and dairy cattle sector. The use of chemical acaricides in the control of this mite has resulted in the emergence of resistant populations. In this sense, alternative control measures using plants as sources of botanical acaricides have shown to be effective. Eugenia pyriformis Cambess is a Brazilian plant with antioxidant and antimicrobial activity; however, there are no reports on its acaricidal activity in the literature. The present study aimed to evaluate the acaricidal and larvicidal potential of E. pyriformis leaf essential oil (EO) on southern cattle tick at different stages of the reproductive cycle. E. pyriformis leaves were collected and dried, and had their EO extracted by hydrodistillation (3h) using a modified Clevenger apparatus. Chemical analysis was performed by gas chromatography coupled with mass spectrometry (GC/MS), and 32 compounds belonging to the sesquiterpene class were identified: hydrocarbons (17.98%) and oxygenated forms (81.96%), with spathulenol (43.65%) and caryophyllene oxide (12.17%) as the most common. The EO was evaluated by the Adult Immersion Test at the concentrations (500.00 to 3.12mg/mL) in which the following parameters were measured: mortality of females (%), hatchability of eggs (%), and product efficiency (%). Larvae were assessed by the Larval Packet Test at concentrations ranging from 25.00 to 0.00004mg/mL. Lethal concentrations (LC) required for killing 50 and 99.9% of adult females and larvae were determined using Probit analysis. LC50 and LC99.9 of EO were 0.06 and 24.60mg/mL and 1,208.80 and 2,538mg/mL for larvae and adult females, respectively. Action of the EO in the free-living cycle of R. (B.) microplus larvae was another parameter assessed. To this end, the larvae were deposited in pots containing Brachiaria decumbens and, after migration to the leaf apex, a solution containing LC99.9 (24.60mg/mL) of the EO was sprayed. After 24h, 72.25% of the larvae had died, indicating stability of the EO when subjected to uncontrolled temperature and humidity conditions. The mechanism of action through which the EO killed the larvae and adult females was investigated by the Bioautographic Method, which showed inhibition of 3.15mg/mL of the EO on the acetylcholinesterase (AChE) enzyme. The results found in the present experiment indicate that E. pyriformis essential oil is an alternative in the control of southern cattle tick in the larval (parasitic) and free-living cycle (non-parasitic) stages under field conditions.(AU)
O Brasil dispõe de um dos maiores rebanhos bovinos comerciais do mundo, sendo natural que junto a esse rebanho, coexista uma enorme quantidade de espécies parasitárias; dentre estes o carrapato Rhipicephalus (Boophilus) microplus que interfere na produtividade animal, causando prejuízos à pecuária de corte e leite. A utilização de acaricidas químicos no controle deste ácaro tem causado o surgimento de populações resistentes e neste sentido, controles alternativos utilizando plantas como fontes de acaricidas botânicos têm se mostrado eficazes. Eugenia pyriformis Cambess é uma planta brasileira com atividades antioxidante e antimicrobiana, entretanto não há relatos da atividade acaricida. O objetivo do presente estudo consistiu na avaliação do potencial acaricida e larvicida do óleo essencial das folhas de E. pyriformis sobre o carrapato bovino nos diferentes estágios do ciclo reprodutivo. As folhas foram coletadas, secas e o OE extraído por hidrodestilação (3 horas) em aparelho Clevenger modificado. A análise química foi realizada por cromatografia gasosa acoplada à espectrometria de massas (CG/EM) sendo identificados 32 compostos, pertencentes à classe sesquiterpenos: hidrocarbonetos (17.98%) e oxigenados (81.96%); tendo como majoritários o spathulenol (43,65%) e caryophylene oxide (12,17%). O OE foi avaliado pelo teste de imersão de adultos nas concentrações (500,00 a 3,12mg/mL) onde foram mensurados os parâmetros: mortalidade das fêmeas (%), eclodibilidade dos ovos (%) e eficiência do produto (%). As larvas foram avaliadas pelo teste de imersão larval (Larval Packet Test) nas concentrações que variaram de 25,00 a 0,00004mg/mL. Foram determinadas as concentrações letais (CLs) necessárias para matar 50 e 99,9% das fêmeas adultas e das larvas utilizando a análise de Probitos. As CL50 e CL99,9 do OE foram (0,06 e 24,60mg/mL) para as larvas e (1.208,80 e 2.538mg/mL) para as fêmeas adultas, respectivamente. Outro parâmetro avaliado em nossa pesquisa foi mensurar a ação do OE no ciclo de vida livre das larvas de R.(B.) microplus; onde as larvas foram depositadas em vasos com Brachiaria decumbens e após migração destas para o ápice das folhas, foi aspergido solução contendo a CL99,9 (24,60mg/mL) do OE. Após 24 horas, 72,25% das larvas morreram indicando que houve estabilidade do OE quando submetido a condições de temperatura e umidade não controladas. O mecanismo de ação pelo qual o OE matou as larvas e fêmeas adultas foi investigado pelo método bioautográfico, indicando uma inibição de 3,15mg/mL do óleo essencial sobre a enzima acetilcolinesterase (AChE). Os resultados encontrados no presente experimento indicaram que o óleo essencial de E. pyriformis é uma alternativa no controle do carrapato bovino no estágio larval (parasitário) e no ciclo de vida livre (estágio não parasitário) em condições de campo.(AU)

Abstract Objective: To evaluate the efficacy of triclosan-coated suture for the reduction of infection in saphenectomy wounds of patients undergoing coronary artery bypass graft (CABG) surgery. Methods: A total of 508 patients who underwent saphenectomy in CABG surgery were included in a prospective, randomized, double-blind trial from February/2011 to June/2014. Patients were randomized into the triclosan-coated suture group (n= 251) and the conventional non-antibiotic suture group (n=257). Demographic (gender and age), clinical (body mass index, diabetes, and use of analgesics), and intraoperative (cardiopulmonary bypass and cross-clamp times) variables and those related to the saphenectomy wound (pain, dehiscence, erythema, infection, necrosis, and hyperthermia) were measured and analyzed. Results: Of the 508 patients who underwent saphenectomy, 69.9% were males and 40.2% were diabetic. Thirty-three (6.5%) patients presented infection: 13 (5.3%) with triclosan and 20 (7.9%) with conventional suture (P=0.281). Among diabetic patients (n=204), triclosan suture was used in 45.1% with four cases of infection; conventional suture was used in 54.9% of them, with 11 cases of infection. Most patients (94.3%) underwent on-pump CABG. Wound pain was observed in 9.9% of patients with triclosan-coated suture and in 17.9% with conventional suture (P=0.011). Wound hyperthermia was found in 1.6% of patients with triclosan-coated suture and in 5.4% of those with conventional suture (P=0.028). Conclusion: Triclosan-coated suture shows lower infection rate in saphenectomy of patients undergoing CABG, although the differences were not statistically significant. Pain and wound hyperthermia were less frequent in patients with triclosan-coated sutures compared with conventional sutures.

Hygiene deficiency causes type 1 (oral) halitosis. There are short and long-term studies on the anti-halitosis effect of mouth rinses but less knowledge on their instant effects. The aim of this study was to compare instant and freshness effects of 8 mouth rinses on type 1 halitosis. Ninety self-reported halitosis patients (19-58 y.o., median 31) were randomly divided into 9 groups. Cysteine (20 mM) challenge test was applied to obtain maximum halitosis level in the mouth of each patient. Single use of 8 different mouth rinses (R1-R8) and tap water (R0) were tested on each group (n=10). Afterward, patients were requested to score oral freshness effect of the mouth rinse on a 5-point scale (0, bad; 5, fresh). Minimum halitosis level was obtained by rinsing with 20 mMol ZnCL2. In each step, oral gas (organic, NH3, SO2, H2S, H2) concentrations were quantified by using a portable multi-gas detector (MX6, IndSci, US). The ANOVA or Kruskal Wallis tests were used to compare the quantitative measurements. R3 (Halitosil Zn) mouth rinse was found to be have the highest instant anti-halitosis effect while the R2 (Colgate plax) had the lowest. The sensation of freshness was highest in R7 (Oxyfresh power mouth rinse lemon-mint) and lowest in R8 (Signal expert protection). The freshness effect was not associated with the anti-halitosis effect (r= 0.185, p=0.608). Mouth rinses containing ZnCl2 without alcohol are instantly effective on halitosis. Mouth rinses containing ethyl and other alcohols (including glycol, sorbitol, menthol, eucalyptol, thymol, xylitol and eugenol) were found to be less effective on halitosis.
La deficiencia de higiene causa halitosis tipo 1 (oral). Se han reportado efectos anti-halitosis a corto o largo plazo de los enjuagatorios bucales, pero se desconocen sus efectos instantáneos. El objetivo de este estudio fue comparar el efecto instantáneo y de frescura de 8 enjuagues bucales en la halitosis tipo 1. Noventa pacientes (19-58 años, mediana 31) que reportaron sufrir halitosis se dividieron aleatoriamente en 9 grupos. Se aplicó la prueba de provocación con cisterna (20 mM) para obtener el máximo nivel de halitosis en la boca de cada paciente. El uso individual de 8 enjuagues bucales diferentes (R1-R8) y agua del grifo (R0) se probó en cada grupo (n = 10). Posteriormente, se pidió a los pacientes que puntuaran el efecto de la frescura oral del enjuague bucal en una escala de 5puntos (0, malo; 5, fresco). El nivel mínimo de halitosis se obtuvo con 20 mMol de ZnCL2 enjuague. En cada paso, se cuantificaron las concentraciones de gases orales (orgánicos, NH3, SO2, H2S, H2) mediante el uso de un detector portátil de múltiples gases (MX6, IndSci, EE. UU.)Se encontró que el enjuague bucal R3 (Halitosil Zn) tiene un mayor efecto antihalitosis instantáneo, mientras que el R2 (Colgate plax) fue el más bajo. El sentido de frescura fue mayor en el enjuague bucal R7 (enjuague bucal Oxyfresh power lemon-mint) mientras que fue bajo en R8 (protección experta de Signal). El efecto de frescura no se asoció con el efecto anti-halitosis (r = 0.185, p=0.608). Los enjuagues bucales que contienen ZnCl2 sin alcohol son instantáneamente efectivos en la halitosis. Se encontró que los enjuagues bucales que contenían etil y otros alcoholes (incluidos glicol, sorbitol, mentol, eucaliptol, timol, xilitol y eugenol) son menos efectivos para el control de la halitosis.

Abstract This study aims to evaluate tissue healing efficacy in burn patients treated with 1% silver sulfadiazine versus other treatments. This is a systematic literature review and meta-analysis of randomized clinical trials performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) and PICO strategy, registered in the International Prospective Register of Systematic Reviews (PROSPERO) under the number CRD42017081057. The review found 71 studies in MEDLINE/Pubmed, 1 in Clinical Trials, 19 in the Cochrane Library, and 4 in LILACS in five manual searches. Of these, 81 studies were pre-selected. After independent analysis by two reviewers, only 11 studies met the inclusion criteria for the review. All studies (n = 11) using alternative treatments to silver sulfadiazine were shown to be superior in the mean time for complete wound healing, with statistically significant differences between experimental and control groups (p <0.00001); mean difference (- 4.26), 95% CI [- 5.96, - 2.56].

ABSTRACT Purpose: Treatment of persistent anal fistula implies a major challenge for surgeons, with risk of additional recurrence and potential continence impairment. We present a non-surgical treatment based on irrigation with silver nitrate 1% solution. Methods: This is a prospective study including patients with persistent anal fistula after surgery, who were treated with silver nitrate 1% solution irrigation from May 2015 to March 2017. Patients with evidence of abscess, presence of >1 external opening and those with bowel inflammatory disease were excluded. 3-5 cc of silver nitrate 1% solution were instilled through a catheter. The procedure was repeated on a weekly basis, conducting a maximum of 7 sessions per patient. Results: 18 patients (13 male, 72.2%) with a median age of 48 years old (IQR 41-55) were treated using silver nitrate 1% solution. A median of 5 sessions per patient was performed (IQR 3-6). The median follow-up period was 18 months (IQR 9-25). After the described period 8 patients' (44.4%) presented complete resolution of the fistula, 2 patients' (11.2%) were classified as partial healing and in 8 patients' (44.4%) the treatment was considered to fail. 6 patients' experienced self-limited pain during instillation, with persistence up to 24 h in 2 of them. Conclusions: Treatment with silver nitrate 1% solution is a minimally invasive procedure, with a favourable safety profile, that can be performed in an outpatients' basis achieving a complete healing rate of 44.4%. Therefore, this method should be considered for the treatment of recurrent or persistent anal fistula.
RESUMO Objetivo: O tratamento da fístula anal persistente é um grande desafio para os cirurgiões, com risco de recorrência adicional e potencial comprometimento da continência. Os autores apresentam um tratamento não cirúrgico baseado na irrigação com solução de nitrato de prata a 1%. Métodos: Este foi um estudo prospectivo incluindo pacientes com fístula anal persistente após a cirurgia que foram tratados com irrigação com solução de nitrato de prata a 1% entre maio de 2015 e março de 2017. Pacientes com evidência de abscesso, presença de mais de uma abertura externa e aqueles com doença inflamatória intestinal foram excluídos. Usando um cateter, instilou-se 3 a 5 cc. de solução de nitrato de prata a 1%. O procedimento foi repetido semanalmente, em um máximo de sete sessões por paciente. Resultados: Um total de 18 pacientes (13 homens, 72,2%) com idade mediana de 48 anos (IQR 41-55) foram tratados com solução de nitrato de prata a 1%. Uma mediana de cinco sessões por paciente foi realizada (IQR 3-6). A mediana do período de acompanhamento foi de 18 meses (IQR 9-25). Após o período descrito, oito pacientes (44,4%) apresentaram resolução completa da fístula, dois pacientes (11,2%) foram classificados como cicatrização parcial e em oito pacientes (44,4%) o tratamento falhou. Seis pacientes apresentaram dor autolimitada durante a instilação, que persistiu por até 24 horas em dois deles. Conclusões: O tratamento com solução de nitrato de prata a 1% é um procedimento minimamente invasivo, com perfil de segurança favorável, que pode ser realizado em regime ambulatorial, atingindo taxa de cura completa de 44,4%. Portanto, este método deve ser considerado para o tratamento da fístula anal recorrente ou persistente.

BACKGROUND Topical treatment of New World cutaneous leishmaniasis can be affected by bacterial coinfection, hyperkeratosis, and transdermal drug delivery. OBJECTIVE The aim of this work was to evaluate the therapeutic response and safety of the topical, sequential use of antiseptic, keratolytic, and pentamidine isethionate (PMD) creams (3-PACK kit) on CL-infected BALB/c mice. METHODS A 0.5% chlorhexidine solution (CGH), 10% salicylic acid (SA), and 3% or 6% PMD were used as antiseptic, keratolytic, and antileishmanial drugs, respectively. During the first seven days, antiseptic, followed by 10% SA gel and PMD cream, were applied topically. Subsequently, treatment was performed only with the antiseptic and PMD creams. Skin irritation, reduction of lesion size (mm2), and parasitic load were observed until 30 days of treatment were completed. FINDINGS The 3-PACK treatment using 6% PMD induced a complete lesion reduction in 3/6 mice and a partial reduction in 1/6 mice, with no parasites observed. In contrast, CGH and SA alone, along with the vehicle, were not effective (p < 0.05). Moderate to severe erythema was observed at the application site. MAIN CONCLUSION The topical 3-PACK using 6% PMD was 67% effective in the treatment of CL by Leishmania (Viannia) braziliensis.

Introducción: Existen varias curaciones para quemaduras. La sulfadiazina de plata se ha usado por años pero las membranas microporosas son cada vez más preferidas. Objetivos: Comparar la eficiencia de las membrana microporosa (Telfa Clear®) versus sulfadiazina de plata (Platsul®) en menores de 15 años hospitalizados por quemadura. Pacientes y Métodos: Estudio de cohorte retrospectivo de 87 pacientes, dividido en 2 grupos comparables en extensión y profundidad de la quemadura, edad y sexo. Durante enero a diciembre 2007 se curaron 52 pacientes con Platsul® y desde enero a octubre 2008 se curaron 35 con Telfa Clear®. Se evalúa tiempos y extensión de reepitelización, porcentaje de injertos, costos, días de hospitalización, número de curaciones, complicaciones, almacenamiento-estabilidad y costos. Estadística no paramétrica para el análisis univariado y regresión logística multivariado en Stata 11.2. Resultados: Los pacientes curados con Platsul® se injertaron más tardíamente y presentan más curaciones. Platsul® es peor evaluado por su almacenamiento-estabilidad y mayores costos. No hay diferencia en la incidencia de infección. Conclusiones: Ambas Técnicas son eficientes en permitir reepitelización, pero Platsul® puede demorar el injerto. La Telfa Clear® es mejor evaluado por el equipo de salud en cuanto a almacenamiento y estabilidad. El menor costo de Telfa Clear® es una ventaja.
Introduction: There are several dressings for burns. Silver sulfadiazine has been used for years but microporous membranes are increasingly preferred. Objectives: To compare the efficiency of microporous membrane (Telfa Clear®) versus silver sulfadiazine (Platsul®) in children younger than 15 years old hospitalized for burns. Patients and Methodology: Retrospective cohort study of 87 patients, divided into 2 comparable groups in extent and depth of the burn, age and sex. During January to December 2007, in 52 patients Platsul® were use and in 35 patients Telfa Clear® were use from January to October 2008. The time and extent of re-epithelialization, percentage of grafts, costs, length of stay, number of dressing change, complications, storage-stability and costs are evaluated. Non-parametric statistics were used for univariate analysis and logistic regression for multivariate analysis en Stata 11.2. Results: Platsul® was associate to a later graft and had a greater number of dressing changes. Platsul® is worst rated for its storage-stability and higher costs. No difference in infection rate was observed. Conclusions: Both techniques are efficient in allowing re-epithelialization, but burns treated with Platsul® were grafted later than when Telfa Clear® was used. Telfa Clear® is best evaluated by the health team in terms of storage and stability. The cost of Telfa Clear® is presented as an advantage.

A infecção de sítio cirúrgico (ISC) é um grande desafio para o paciente, equipe e instituições de saúde. Um fator de risco importante na patogênese das infecções cirúrgicas ortopédicas refere-se à pele do paciente. O banho do paciente com soluções antissépticas, no pré-operatório é recomendado como medida para reduzir o risco de ISC, apesar das controvérsias. O objetivo deste estudo foi avaliar o efeito da intervenção de enfermagem, banho pré-operatório, utilizando as soluções de gluconato de clorexidina a 4%, PVP-I degermante a 10% e sabão sem antisséptico, na prevenção de ISC, em pacientes submetidos à cirurgia eletiva de artroplastia do quadril e estimar a frequência de reações alérgicas causadas pelo uso das soluções. Estudo do tipo ensaio clínico, randomizado, controlado, com mascaramento do pesquisador, paciente e estatístico, utilizando dois grupos de intervenção (clorexidina; PVP-I) e um controle (sabão sem antisséptico). A amostra foi composta por 162 pacientes adultos, submetidos à cirurgia eletiva de artroplastia total do quadril, entre agosto/2015 e outubro/2017, sem infecção no local cirúrgico e alergia às soluções e não portadores nasais de Staphylococcus aureus. A randomização foi realizada por um programa de computador. Utilizados os critérios de descontinuidade de tratamento e a análise por intenção de tratar. Cada grupo foi composto por 54 pacientes. Na consulta de enfermagem os pacientes foram orientados pela enfermeira pesquisadora a tomarem dois banhos: na véspera da cirurgia no domicílio e no dia da cirurgia no hospital. O banho no hospital foi realizado por profissional de enfermagem. Para o banho o paciente recebia um envelope pardo fechado contendo o frasco da solução sorteada, quatro esponjas e um manual que orientava sobre o procedimento. O desfecho primário foi ISC e os pacientes foram monitorados até 90 dias de pós-operatório por meio de telefonemas e nas consultas de egressos ambulatorial. O programa Statistical Package for the Social Sciences (SPSS), versão 19.0, foi utilizado para análise dos dados. O efeito aos tratamentos foi medido comparando os grupos intervenção e controle por meio da incidência de ISC, risco relativo, redução absoluta de risco. As características clínicas/epidemiológicas/cirúrgicas foram similares entre os pacientes nos três grupos. A incidência de ISC em cada grupo foi 5,5% (3/54) [IC95% 1,2-15,4]. A taxa de infecção superficial foi 4,9% e profunda 0,6%. O tempo médio para o surgimento das infecções foi 19 dias (DP ± 7,4). Não houve diferença estatística significativa entre os grupos (p=1,00). Um paciente apresentou reação alérgica com o uso da solução de PVP-I. A taxa de adesão aos dois banhos foi de 99,4% (161/162). Os resultados corroboram recentes revisões sistemáticas que não encontraram diferença nas taxas de infecção cirúrgica quando o banho pré-operatório foi realizado com soluções antissépticas ou sabão. A consulta de enfermagem no pré-operatório pode impactar a taxa de infecção profunda na cirurgia eletiva de artroplastia do quadril. O uso de soluções antissépticas pode ocasionar reações alérgicas na pele do paciente, durante o banho e precisa ser monitorada. É necessário cautela ao recomendar o banho pré-operatório com solução antisséptica como estratégia para reduzir infecção de sítio cirúrgico. A orientação do paciente no pré-operatório de cirurgia eletiva de artroplastia do quadril, quando realizada pelo enfermeiro, pode melhorar a qualidade do cuidado prestado ao paciente cirúrgico.

Surgical site infections (SSI) are a major challenge for the patient, staff, and health institutions. An important risk factor in the pathogenesis of orthopedic surgical infections refers to the patient's skin. The patient's bath with antiseptic solutions in the preoperative period is recommended as measure to reduce the risk of SSI, despite controversies. The objective of this study was to evaluate the effect of the nursing intervention, preoperative bath, using 4% chlorhexidine gluconate solutions, 10% PVP-I and non-antiseptic soap in the prevention of SSI in patients submitted to elective hip arthroplasty surgery and the frequency of allergic reactions caused by the use of the solutions. Randomized, controlled clinical trial with masking of the researcher, patient and statistician using two intervention groups (PVP-I, chlorhexidine) and one control (non-antiseptic soap). The sample was consisted of 162 adult patients undergoing elective total hip replacement between August/2015 to October/2017, without infection at the surgical site and allergy solutions and non-nasal carriers of Staphylococcus aureus. The randomization was performed by a computer program. The criteria for treatment discontinuity and intention-to-treat analysis were used. Each group consisted of 54 patients. In nursing consultation patients were instructed by the research nurse to take two baths: the day before the surgery at home and the day of the surgery in the hospital. The bath in the hospital was performed by a nursing professional. For the bath the patient received a closed brown envelope containing the bottle of the solution drawn, four sponges, and a manual that guided about the procedure. The primary outcome was ISC and the patients were monitored up to 90 postoperative days by phone calls and outpatients visits. The Statistical Package for Social Sciences (SPSS), version 19.0, was used for analysis of the data. The effect on treatments was measured by comparing intervention and control group by incidence of ISC, Relative Risk and Absolute Risk Reduction. Clinical/epidemiological/surgical characteristics were similar among the patients of the three groups. The incidence of SSI in each group was 5.5% (3/54) [IC95% 1,2-15,4]. The superficial infection rate was 4.9% and deep 0.6%. The mean time to onset of infection was 19 days (SD ± 7.4). There was no statistically significant difference between the groups (p = 1.00). One patient presented an allergic reaction with the use of the PVP-I solution. The rate of adherence to the two baths was 99.4% (161/162). The results of this study corroborate recent systematic reviews that found no difference in surgical infection rates when the preoperative bath was performed with antiseptic solutions or soap. The preoperative nursing consultation may impact the rate of deep infection in elective hip arthroplasty surgery. The use of antiseptic solutions may cause allergic reactions on the patient's skin during bathing and needs to be monitored. Caution is required when recommending the preoperative bath with antiseptic solution as a strategy to reduce surgical site infection. The orientation of the patient in the preoperative period of elective hip arthroplasty surgeries performed by the nurse can improve the quality of care provided to the surgical patient.

Staphylococcus aureus colonization in the nares of patients undergoing elective orthopedic surgery increases the potential risk of surgical site infections. Methicillin-resistant S. aureus (MRSA) has gained recognition as a pathogen that is no longer only just a hospital-acquired pathogen. Patients positive for MRSA are associated with higher rates of morbidity and mortality following infection. MRSA is commonly found in the nares, and methicillin-sensitive S. aureus (MSSA) is even more prevalent. Recently, studies have determined that screening for this pathogen prior to surgery and diminishing staphylococcal infections at the surgical site will dramatically reduce surgical site infections. A nasal mupirocin treatment is shown to significantly reduce the colonization of the pathogen. However, this treatment is expensive and is currently not available in China. Thus, in this study, we first sought to determine the prevalence of MSSA/MSRA in patients undergoing elective orthopedic surgery in northern China, and then, we treated the positive patients with a nasal povidone-iodine swab. Here, we demonstrate a successful reduction in the colonization of S. aureus. We propose that this treatment could serve as a cost-effective means of eradicating this pathogen in patients undergoing elective orthopedic surgery, which might reduce the rate of surgical site infections.
