ABSTRACT

El pegamento basado en cianoacrilato posee una gran capacidad de adherencia a los tejidos, representando un problema cuando se encuentra en el oído externo debido a sus características anatómicas particulares. Se presenta un caso clínico de cuerpo extraño de cianoacrilato que ocluye el conducto auditivo externo y el tímpano, alterando la audición. Se describen los hallazgos y los intentos de extracción utilizando las alternativas terapéuticas descritas en la literatura, sin obtener resultados positivos, debiendo recurrir a la extracción quirúrgica. Además, se presentan detalles del procedimiento y los resultados. El paciente recupera la audición y la normalidad anatómica.


Cyanoacrylate-based glue has a great capacity for adhering to tissue, which is a problem when it is placed in the ear canal due to the anatomy of this structure. A clinical case of a cyanoacrylate foreign body occluding the external auditory canal and the tympanic membrane is presented. The therapeutics alternatives described in the literature used in the case failed, so, it was surgically removed by drilling the glue. Details of the procedure and results are presented. The patient recovers the hearing and anatomical normality.

ABSTRACT

ABSTRACT Background: In natural history of cirrhosis, variceal bleeding is one of the earliest decompensations to happen, and, if adequately managed, survival is improved. Gastric varices have challenges in management due to their location, size and propensity to bleed. The N-butyl 2-cyanoacrylate (NBC) glue application has emerged as definitive therapy in bleeding gastric varices. Here we present our experience with use of NBC in management of gastric and difficult cases of esophageal varices. Methods: A total of 75 patients underwent NBC glue application for varices which included 69 patients with gastric varices and six patients with esophageal varices. All the procedures were done with flexible endoscope and sclerotherapy needle after due precautionary measures. Results: Hemostasis was varices in all patients after endotherapy. The average quantity of glue used was 2.75±0.95 mL. Complete obliteration with single session of NBC application was achieved in 55 patients. Re-bleeding occurred in five patients within 5 days of index event. 20 patients had in-hospital mortality but none was related to gastrointestinal bleeding. 6-week all-cause mortality was 26 (35%). Conclusion: Glue therapy with NBC is a life saving therapy in patients with bleeding gastric varices and esophageal varices not amenable to endoscopic variceal ligation or sclerotherapy.


RESUMO Contexto: Na história natural da cirrose, o sangramento de varizes é uma das primeiras descompensações a acontecer e, se adequadamente controlada, a sobrevivência é melhorada. Varizes gástricas têm desafios na sua gestão devido à sua localização, tamanho e propensão a sangrar. A aplicação de cola N butil 2-cianoacrilato (NBC) surgiu como terapia definitiva em varizes gástricas sangrantes. Apresentamos nossa experiência com o uso da NBC na gestão de casos gástricos e difíceis de varizes esofágicas. Métodos: Um total de 75 pacientes foram submetidos à aplicação de cola NBC para varizes que incluiu 69 pacientes com varizes gástricas e seis pacientes com varizes de esôfago. Todos os procedimentos foram feitos com endoscópio flexível e agulha de escleroterapia após as devidas medidas de precaução. Resultados: A hemostasia foi alcançada em todos os pacientes após a endoterapia. A quantidade média de cola utilizada foi de 2,75+0,95 mL. A obliteração completa com sessão única de aplicação da NBC foi alcançada em 55 pacientes. O reexame ocorreu em cinco pacientes dentro de 5 dias após o evento de índice. 20 pacientes tiveram mortalidade hospitalar, mas nenhum foi relacionado com o sangramento gastrointestinal. A mortalidade após 6 semanas foi de 26 (35%). Conclusão: A terapia de cola com a NBC é uma terapia que salva vidas em pacientes com varizes gástricas hemorrágicas e varizes esofágicas não condizíveis à ligadura endoscópica ou escleroterapia.

ABSTRACT

ABSTRACT: The aim of this study is to evaluate the effect of two ethyl cyanoacrylate-based adhesives on the growth of Candida albicans biofilms on a heat-polymerized resin, after 7, 14, and 30 days of exposure. Ninety circular (10 x 2 mm) heat-polymerized resin specimens were equally divided into three groups: control, conventional ethyl cyanoacrylate (ECAc), and ethyl cyanoacrylate gel (ECAg). Two layers of 50 µL of each material were applied to the respective groups. C. albicans SC5314 strain was activated and standardized to 107 cells/mL-1. Specimens were immersed in 1 mL of artificial saliva and deposited in 1 mL fungal suspension, washed, and immersed in 1 mL of RPMI for 7, 14, and 30 days. The medium was changed at 48-hour intervals. The final suspension was diluted (10 -1 to 10-4) and deposited on Sabouraud dextrose agar for 48 h at 37 °C. After this period, the colonies were quantified using the CFU/mL calculation. Data were evaluated using one- way ANOVA and Tukey's test for post-hoc analysis (P=0.05). It was observed that both adhesives significantly reduced (P<0.05) biofilm formation compared to the control at all evaluated periods. In conclusion, an immediate and long-term inhibitory effect on C. albicans biofilm formation was observed.


RESUMEN: El objetivo del estudio fue evaluar el desarrollo microbiano en superficies de resina acrílica de termopolimerización, acondicionadas previamente, con adhesivos a base de etil cianoacrilato después de 7, 14 y 30 días de exposición en biofilm de Candida albicans. Noventa muestras circulares (10 x 2 mm) de resina acrílica de termopolimerización se dividieron por igual en tres grupos: control, etil cianoacrilato convencional (ECAc) y etil cianoacrilato en gel (ECAg). Se aplicaron dos capas de 50 µl de cada adhesivo en cada muestra. Simultáneamente, se activó la cepa C. albicans SC5314 y se estandarizó a 107 células/ml-1. Las muestras fueron sumergidas en 1 mL de saliva artificial por dos horas y luego se depositó 1 mL de suspensión fúngica por una hora. En seguida cada muestra se lavó y se sumergió en 1 mL de RPMI durante 7, 14 y 30 días, con cambios del medio a cada 48 horas. La suspensión final se diluyó (10-1 a 10-4) y se depositó en agar dextrose Sabouraud durante 48 h a 37° C. Después de este período, las colonias se cuantificaron mediante el cálculo de UFC / mL. Los datos obtenidos se evaluaron por medio del test ANOVA-one way y la prueba de Tukey para el análisis post- hoc (p = 0,05). Se observó que ambos adhesivos redujeron significativamente (P<0,05) la formación del biofilm de Candida albicans al ser comparados con el grupo control en todos los períodos evaluados. Los adhesivos a base de etil cianoacrilato poseen un efecto inhibidor de biofilm de Candida albicans de hasta 30 días, al ser aplicados dos veces en resinas acrílicas de termopolimerización.

ABSTRACT

RESUMEN El objetivo de este estudio fue comparar el tiempo de cicatrización entre N-butil cianocrilato (NBC) y ácido poliglicólico (AC) sobre el cierre tisular en caninos sometidos a operaciones de esterilización. Se realizó un estudio observacional, comparativo y descriptivo sobre una población de 80 perros (Canis familiaris) vivos. Los animales se dividieron en cuatro grupos de 20 perros cada uno según sexo y material de sutura, así: primero grupo, hembras que recibieron NBC; segundo grupo, machos y NBC; tercero grupo, hembras y AC como medio de sutura en piel y cuarto grupo, machos y AC. La técnica quirúrgica en hembras fue oforosalpingohisterectomia y en machos orquiectomia. El tiempo de cierre fue estadísticamente (p < 0,05) menor en los grupos de machos y hembras con el adhesivo NBC comparado con los dos grupos tratados con AC. Se concluye que el NBC es un material seguro y eficaz como medio de fijación tisular en ambas técnicas quirúrgicas que disminuye los días de cierre y recuperación.


ABSTRACT The aim of this study was to compare N-butyl cyanoacrylate (NBC) and polyglycolic acid (AC) in tissue closure in canines subjected to sterilization operations. An observational, comparative and descriptive study was conducted in a population of 80 living dogs (Canis familiaris). The animals were divided into 4 groups of 20 dogs each, according to gender and suture material: the first group consisted of females that received NBC; the second group consisted of males that received NBC; the third group consisted of females that received AC as skin suture; and the fourth group was formed by males that received AC. The surgical technique in females was salpingo-oophorectomy, and in males it was orchiectomy. The closure time was statistically (p < 0.05) lower in the male and female groups with the NBC adhesive in comparison to the two groups treated with AC. It was concluded that NBC is a safe and effective material for tissue fixation in both surgical techniques, decreasing times of closure and recovery.

ABSTRACT

Las várices gástricas están presentes en cerca de un tercio de los pacientes con hipertensión portal y el sangrado de las mismas representa una causa significativa de mortalidad. El tratamiento de primera línea es la obturación con N-butil-2-cianoacrilato, que si bien es seguro no está libre de complicaciones. Presentamos el caso de un paciente de 61 años de edad con antecedente de cirrosis criptogénica que se presentó a la consulta febril, taquicárdico e hipoxémico después de la obturación endoscópica con N-butil-2-cianoacrilato. Las imágenes mostraron embolia pulmonar bilateral del material obturante. El objetivo de este trabajo es destacar las manifestaciones clínicas y las imágenes de esta situación para ayudar a su diagnóstico precoz y diferenciarla de otras entidades que requieren un tratamiento específico.


Gastric varices occur in one-third of patients with portal hypertension. Bleeding from gastric varices remains a significant cause of death. Currently the first-line of treatment for gastric varices is endoscopic obliteration with N-butyl-2-cyanoacrylate. Though relatively safe, this option has several well-known complications. We report the case of a 61-year-old male patient with cryptogenic cirrhosis, who presented with fever, tachycardia and hypoxemia after endoscopic obliteration with N-butyl-2-cyanoacrylate. Radiographic findings were consistent with pulmonary embolism of the sclerosing substance. The aim of this case report is to emphasize the clinical and radiological findings of this complication in order to distinguish it from other similar medical conditions and prevent a delay in diagnosis.

ABSTRACT

La principal causa de hemorragia de vías digestivas altas es la enfermedad ulcerosa del estómago y/o duodeno (Enfermedad ulceropéptica). Cada vez y con mayor frecuencia se presentan pacientes con sangrado originado en várices gástricas, quizás debido al número creciente de pacientes que las presentan como una secuela de la hipertensión portal causada a su vez por problemas hepáticos, especialmente por la cirrosis. Las opciones actuales de tratamiento de las várices gástricas incluyen desde métodos preventivos o profilácticos, hasta los propiamente terapéuticos mediante el uso de medicamentos (vasopresina, somatostatina y sus análogos), las derivaciones portosistémicas transyugulares (TIPS, por sus siglas en inglés) los métodos endoscópicos y la cirugía. Los métodos endoscópicos incluyen el uso de bandas y de inyección de sustancias esclerosantes, o de sustancias obturativas como el N-Butyl-2-cianoacrilato (Histoacryl®). Desde hace poco tiempo, y basados en la literatura cada vez con mejores niveles de evidencia y grados de recomendación, hemos empezado a usar el cianoacrilato en la Clínica Universitaria Colombia. Presentamos nuestra casuística y realizamos una revisión del tema


The main causes of upper digestive tract bleeding are ulcers in the stomach and/or duodenum (peptic ulcer disease). With increasing frequency, patients are being seen who have bleeding gastric varices. This may be due to the increasing number of patients who have portal hypertension caused in turn by liver problems, especially cirrhosis. Current options for treatment of gastric varices range include preventive and prophylactic methods. These include therapy using drugs including vasopressin, somatostatin and their analogs, transjugular intrahepatic portosystemic shunts (TIPS) endoscopic methods and surgery. Endoscopic methods include the use of bands and injection sclerotherapy and sealants such as N-Butyl-2-cyanoacrylate (Histoacryl ®). Recently, on the basis of literature with increasingly higher levels of evidence and recommendations, we have started using cyanoacrylate at the Clínica Universitaria Colombia. We present our cases and we review the issue.

ABSTRACT

Objetivo: Estimar a custo-efetividade do n-butil-cianoacrilato (NBCA) para fixação de telas em pacientes submetidos a hernioplastias inguinais por reparo aberto ou laparoscópico, sob a perspectiva da Saúde Suplementar do Brasil. Métodos: Foi elaborado modelo analítico de decisão para estimar a razão de custo efetividade incremental (RCEI) em horizonte de tempo de um ano após procedimento cirúrgico com o uso do adesivo sintético versus técnicas tradicionais de fixação (sutura e grampos). Alternativamente, o uso de NBCA foi comparado à cola de fibrina. Os desfechos clínicos avaliados foram incidência de dor aguda e crônica. A estimativa de custos médicos diretos totais para as diferentes abordagens cirúrgicas e terapia da dor foi elaborada a partir da opinião de especialistas e coletadas em bases de dados secundárias. Resultados: A RCEI obtida através do modelo evidenciou economia substancial de recursos financeiros relacionada ao uso de NBCA de aproximadamente R$ 2.800 por procedimento após reparo laparoscópico e R$ 60 reais por procedimento para reparo aberto, resultados direcionados majoritariamente pela menor tendência de dor (efetividade incremental de 21,74% em termos de dor evitada) versus métodos de fixação tradicional. No cenário alternativo, no qual comparou-se NBCA com a cola biológica (adesivo de fibrina), atingiu-se economia financeira com nível de efetividade equivalente do ponto de vista estatístico entre os comparadores. Conclusão: Pode-se atribuir que o uso de NBCA para fixação de telas em cirurgias de reparo de hérnia inguinal constitui alternativa segura, efetiva e viável economicamente, quando comparado tanto a técnicas de fixação tradicionais como à cola biológica.


Objective: To estimate the cost-effectiveness of n-butyl-cyanoacrylate (NBCA) for mesh fixation in patients undergoing inguinal hernia repair by open or laparoscopic methods, from the perspective of the Brazilian supplementary health sector. Methods: A decision model was developed to estimate the incremental cost-effectiveness ratio (ICER) in time horizon of one year after surgery with the use of synthetic adhesive versus traditional fixation techniques (suture and staples). Alternatively, the use of NBCA was compared to the fibrin glue. Clinical outcomes applied to the model were incidence of acute and chronic pain. The estimation of total direct medical costs for surgical approach and pain therapy was developed based on experts' opinions and collected from secondary databases. Results: The ICER obtained through the model indicated substantial savings of financial resources related to the use of NBCA of approximately 2,800 BRL per procedure after laparoscopic repair and 60 BRL per procedure for open repair, results primarily due to the lower tendency of pain (incremental effectiveness of 21.74% in terms of avoided pain) versus traditional fixation methods. In the alternative scenario, which compared NBCA with biological glue (fibrin glue), it was achieved financial savings, with statistically equivalent level of effectiveness among the comparators. Conclusion: The use of NBCA for mesh fixation in inguinal hernia repair surgery is a safe, effective and feasible alternative from an economic point of view, when compared to both traditional fixation techniques as the biological glue.

ABSTRACT

The aim of the present study was to review the literature regarding the utilization of 2-octyl cyanoacrylate's (Dermabond®, Ethicon US, USA) as a tissue adhesive in dentistry; also, to report its use in the stabilization and fixation of a free gingival graft, indicated to increase the width of the keratinized attached mucosa at the lower incisive region. Literature analysis revealed numerous indications for this tissue adhesive in the medical field related to maxillofacial injuries. In dentistry, clinical reports, as well as controlled clinical studies conducted in humans and in animal models, using histological analysis described positive results for the use of different cyanoacrylate-based tissue adhesives. These studies reported that the use of tissue adhesives reduced the surgical procedure time period, eliminated postoperative visits as well as the discomfort of suture removal and, in addition, did not interfere with the clinical repair process. Favorable results, like the ones described in the literature, were obtained in the present case report using Dermabond®.


O objetivo do presente estudo foi revisar a literatura pertinente sobre a utilização do 2-octil cianoacrilato (Dermabond®, Ethicon US, USA) como adesivo tecidual na Odontologia, assim como relatar seu uso na estabilização e fixação de um enxerto gengival livre indicado para aumento da mucosa ceratinizada inserida na região dos incisivos inferiores. A análise da literatura revelou ampla aplicabilidade deste adesivo tecidual na área médica relacionada aos ferimentos maxilofaciais. Na Odontologia existem relatos clínicos e estudos controlados em humanos e em modelos animais, descrevendo resultados positivos, inclusive por meio da análise histológica, sobre a utilização de diferentes adesivos teciduais, à base do cianocrilato. Estes estudos relataram que o uso dos adesivos teciduais, reduz o tempo operatório, elimina visitas pós-operatórias, não apresenta o desconforto da remoção de suturas, além de não interferir no processo de reparo clínico. Resultados favoráveis como os descritos na literatura, foram obtidos no presente relato de caso com a utilização do Dermabond®.

ABSTRACT

The objectives of this study were to compare surgical techniques and the effects of using n-butyl 2-cyanoacrylate and bovine amniotic membrane to repair perforated lesions in corneas. Penetrating keratoplasty was performed in sixty New Zealand White rabbits under general anesthesia. Group 1 (G1) was treated with n-butyl 2-cyanoacrylate, group 2 (G2) received a fragment of amniotic membrane through the anterior chamber and application of n-butyl 2-cyanoacrylate over the lesion, group 3 (G3) was treated with the same technique as G2 with the addition of an amniotic membrane bandage covering the cornea and sutured in the limbus region, and group 4 (G4) was treated with an amniotic membrane sutured to the lesion and an amniotic membrane bandage sutured in the limbus region. Clinical, histological and histomorphometric examinations of the corneas were performed. The membrane acted as a barrier for aqueous humor in G2 and G3, thereby keeping the surface dry for adhesive application; it also prevented the adhesive from contacting intraocular structures. The groups treated with amniotic membrane and surgical adhesive showed better results than the groups treated with either material alone. Thus, the combination of the membrane with the adhesive is recommended for this type of lesion...


Os objetivos deste estudo foram comparar técnicas cirúrgicas e efeitos do n-butil 2-cianoacrilato e da membrana amniótica bovina na reparação de lesões perfuradas em córneas. Sessenta coelhos da raça Nova Zelândia Branca foram submetidos à ceratoplastia penetrante sob anestesia geral. O grupo 1 (G1) foi tratado com n-butil 2-cianoacrilato; o grupo 2 (G2) recebeu um fragmento de membrana amniótica pela câmara anterior e aplicação de n-butil 2-cianoacrilato sobre a lesão; o grupo 3 (G3) foi tratado com a mesma técnica aplicada ao G2, adicionando-se uma bandagem de membrana amniótica cobrindo a córnea e suturada à região do limbo; e o grupo 4 (G4) foi tratado com membrana amniótica suturada nas bordas da lesão e bandagem de membrana amniótica suturada na região do limbo. Foram realizados exames clínico, histológico e histomorfométrico. A membrana atuou como barreira contra o extravasamento do humor aquoso nos grupos 2 e 3, manteve a superfície seca para posterior aplicação do adesivo e impediu o contato do adesivo com as estruturas intraoculares. Os grupos tratados com o adesivo associado à membrana amniótica demonstraram melhores resultados do que aqueles tratados com cada material isoladamente. Assim, a combinação da membrana com o adesivo é indicada neste tipo de lesão...

ABSTRACT

Objetivo: avaliar a precisão dimensional de modelos de gesso tipos III e IV submetidos a diversos tipos de fraturas, seguidas de colagem com cianoacrilato. Materiais e mé-todo: a amostra foi constituída por 80 modelos de gesso obtidos a partir de moldes de silicone de adição Zetala-bor Platinum®, provenientes de um modelo mestre em aço inox, com dois pilares. Foram formados 2 grupos (n = 40): Grupo 1-Modelos de gesso tipo III e Grupo 2-Mo-delos de gesso tipo IV. Cada grupo foi subdividido em: Controle (n = 10) Modelos de gesso sem fratura; Experi-mental 1 (n = 10) Modelos de gesso colados com adesi-vo a base de cianoacrilato SuperBonder® após fratura no espaço protético, entre os dois pilares; Experimental 2 (n = 10) Modelos de gesso colados após fratura horizontal nos pilares, simulando fratura, ocorrida durante a remo-ção do modelo do molde; Experimental 3 (n = 10) Mo-delos de gesso colados após fratura simulando acidente de queda de uma bancada de laboratório. As unidades amostrais foram mensuradas com paquímetro digital. Os dados foram processados e submetidos à análise estatís-tica (teste de Shapiro-Wilk e teste t student). Resultados: os modelos de gesso fraturados e colados com cianoacri-lato exibiram alterações dimensionais lineares quando comparados aos respectivos controles. Os modelos de gesso tipo III do Grupo 1, se comportaram de forma di-ferente, quando comparados aos modelos de gesso tipo IV do mesmo grupo. Conclusão: a colagem de pilares em modelos de gesso de prótese fixa, sem padronização, põe em risco a precisão dimensional desses.

ABSTRACT

Introducción: El cianoacrilato de butilo es un material de síntesis de tejidos, presenta innumerables ventajas como un tiempo de aplicación corto, fácil ejecución, carácter hemostático, bacteriostático, biodegradable y una adecuada fuerza tensil. Objetivo: Evaluar histológicamente la biocompatibilidad del cianoacrilato de butilo en el lomo de rata en comparación con la seda negra trenzada y la poliglactina 910. Materiales y métodos: Se emplearon 36 ratas albinas de raza Wixtar. Se dividieron aleatoriamente en 4 grupos (A, B, C y D) correlacionados con los periodos de sacrificio (3°, 7°, 14° y 21° día) respectivamente. Se realizaron 3 incisiones de 2 cm de longitud en el lomo de rata. Los parámetros histológicos fueron: infiltrado inflamatorio de células polimorfonucleares, fibroblastos jóvenes y engrosamiento de la epidermis. Resultados: El cianoacrilato de butilo ocasionó menor infiltrado polimorfonuclear en comparación con los otros materiales utilizados. Los picos de proliferación fibroblástica en los grupos tratados con cianoacrilato de butilo fueron superiores al resto. El engrosamiento de la epidermis mostró la alta capacidad mitótica de los queratinocitos para remodelar el epitelio. Al 14° y 21° día, la mayoría de los tejidos tratados con cianoacrilato de butilo ya se encontraban totalmente remodelados en comparación con el resto. Conclusiones: El cianoacrilato de butilo es un material biocompatible con los tejidos, permitiendo disminuir el tiempo de cicatrización de los mismos.


Introduction: N-Butyl-cyanoacrylate is a tissue-synthesis material. It offers countless advantages: short application time, easy execution, as well as possessing hemostatic character. This material is bacteriostatic, biodegradable, and exhibits suitable tensile strength. Objective: The objective of the present paper was the histological evaluation of n-butyl-cyanoacrylate biocompatibility on rats dorsum (spine), compared to braided black silk and Polyglactin 910. Materials and Methods: Thirty six Wixtar albino rats were used for the procedure. They were randomly divided into four groups (A, B, C, D) related to the time of sacrifice (3rd, 7th, 14th and 21st day) respectively. On the rats' spine, three 2 cm long incisions were performed. Histological parameters were as follows: polymorphonuclear cell inflammatory infiltrate, young fibroblasts and epidermis thickening. Results: N-butyl-cyanoacrylate caused lesser polymorphonuclear infiltrate when compared to other used materials. Fibroblast proliferation peaked in groups treated with n-butyl-cyanoacrylate when compared to the rest. Epidermis thickening showed high mitotic ability of keratocytes to remodel epithelium. At the 14th and 21st days most tissues treated with N-Butyl-cyanoacrylate were found to be completely remodeled when compared to the rest. Conclusion: N-butyl-cyanoacrylate was shown to be the most biocompatible material, since it elicited shortest healing time.

ABSTRACT

Las ventajas de los adhesivos en base a cianoacrilatos para uso en cierre de heridas cutáneas ha sido demostrada, pero escasos estudios reportan el uso del etil-cianoacrilato a nivel nacional. El objetivo fue comparar aspectos morfológicos de cicatrización en piel de conejo entre etil-cianoacrilato y sutura. Utilizamos 10 conejos machos adultos, divididos en 2 grupos de 5 animales, del Centro de Cirugía Experimental de la Universidad de La Frontera, Chile. Al grupo experimental se le realizaron dos incisiones, una en cada lado del dorso del tórax, 4 cm de largo, atravesando epidermis y dermis. La incisión derecha fue cerrada con etil-cianoacrilato, la izquierda con punto intradérmico de ácido poliglicólico. Se tomaron biopsias a los días 7, 14 y 21 días postoperatorio. Al día 7, la incisión tratada con etil-cianoacrilato presentó una reacción inflamatoria moderada, con infiltración moderada de PMN. Las biopsias de sutura presentaban una etapa de regeneración más avanzada, sin presentar desarrollo epidérmico. Al día 14, las incisiones tratadas con etil-cianoacrilato se encontraban en la fase final de la etapa inflamatoria, mientras que las biopsias de sutura se encontraban ya en etapa proliferativa. Al día 21, ambos tipos de cierre se encontraban en etapa de remodelación, con epidermis gruesa y lámina basal formada. La dermis presentó tejido conectivo denso irregular, escasos folículos pilosos y glándulas sebáceas. El etil-cianoacrilato, como adherente cutáneo, es una buena alternativa de uso, mostrando una adecuada biocompatibilidad. Presentando una reacción inflamatoria moderada, limitada y de corta duración a nivel dérmico. La cicatriz logra mejores resultados estéticos con respecto a las incisiones cerradas con sutura. Se debe considerar su uso limitado a sitios no expuestos a movimientos y de baja tensión...


The advantages of cyanoacrylate based adhesives for use in cutaneous wound closure has been demonstrated, but few studies reporting the use of ethyl cyanoacrylate nationwide. The objective was to compare morphological aspects of healing in rabbit skin between ethyl-cyanoacrylate and suture. We used 10 adult male rabbits divided into 2 groups of 5 animals, the Center for Experimental Surgery, Universidad de La Frontera, Chile. The experimental group was subject to two incisions, one at each side of the dorsum of the thorax, 4 cm long, spanning epidermis and dermis. The incision was closed with ethyl right-cyanoacrylate, intradermal left with point of polyglycolic acid. Biopsies were taken at days 7, 14 and 21 days postoperatively. At day 7, the incision treated with ethyl cyanoacrylate presented a mild inflammatory reaction with moderate infiltration of PMNs. Suture biopsies showed a more advanced stage of regeneration, without presenting epidermal development. At day 14, the incisions treated with ethyl cyanoacrylate were in the final phase of the inflammatory stage, while suture biopsies were already in proliferative stage. At day 21, closing both types were remodeling stage, with thicker epidermis and basal lamina formed. The dermis showed irregular dense connective tissue, poor hair follicles and sebaceous glands. Ethyl-cyanoacrylate as Skin Adhesive is a good alternative use, showing adequate biocompatibility. Featuring a moderate inflammatory reaction, limited and of short duration dermal level. The scar achieves better cosmetic results regarding the incisions closed with sutures. Consideration should be limited to use low-tension sites not exposed to movements...

ABSTRACT

OBJETIVO: Evaluar el éxito terapéutico de la inyección de N-butil-2-cianoacrilato en el tratamiento de las várices gástricas. MATERIALES Y MÉTODOS: Estudio transversal que incluyó 33 pacientes con várices gástricas que sólo recibieron terapia endoscópica con cianoacrilato entre el 2006 al 2010. El cianoacrilato fue inyectado intravaricealmente en una dilución 1:1 con lipiodol hasta obtener la obturación de las várices. La situación terapéutica fue: Hemorragia activa, várices con estigmas de sangrado reciente y profilaxis secundaria. El éxito del tratamiento se evaluó según la hemostasia, recurrencia de sangrado y obturación. RESULTADOS: De los 33 pacientes, 3 (9.1%) fueron por hemorragia activa, 20 (60.6%) con estigmas de sangrado reciente y 10 (30.3%) como profilaxis secundaria. Las várices fueron GOV2, 17 (51.5%); IGV1, 14 (42.4%) y GOV1, 2 (6.1%). Se logró hemostasia total en 21 (91.3%) pacientes con sangrado agudo o reciente y en 2 (66.7%) de 3 sujetos con sangrado activo. En 5 (15.6%) pacientes hubo recurrencia de sangrado y 2 de ellos recibieron cianoacrilato con éxito de hemostasia. Se logró obturación en 25 (75.8%) del total de pacientes. Cuatro pacientes fallecieron, uno por fracaso del control de sangrado. La mayor severidad de clasificación Child-Pugh se relacionó con falla terapéutica (p=0.034). La complicación principal fue el sangrado post-inyección del cianoacrilato. CONCLUSIONES: Nuestros resultados favorecen el uso de cianoacrilato en el tratamiento de várices gástricas, con raras complicaciones mayores.


OBJECTIVE: To evaluate the therapeutic success of the injection of N-butyl-2-cyanoacrylate in the treatment of gastric varices. METHODS: Cross-sectional study included 33 patients with gastric varices who only received cyanoacrylate endoscopic therapy between 2006 and 2010. Intravariceally, cyanoacrylate was injected in a 1:1 dilution with lipiodol until the obliteration of varices. The therapeutic situation was: active bleeding, varices with stigmata of recent bleeding and secondary prophylaxis. Treatment success was evaluated according to hemostasis, recurrent bleeding and obliteration. RESULTS: Of the 33 patients, 3 (9.1%) were for active bleeding, 20 (60.6%) with stigmata of recent bleeding and 10 (30.3%) as secondary prophylaxis. Gastric varices were GOV2, 17 (51.5%); IGV1, 14 (42.4%); GOV1, 2 (6.1%). Hemostasis was achieved in 21 (91.3%) and in 2 (66.7%) of 3 patients with active bleeding. Five (15.6%) patients had recurrent bleeding and 2 of them used cyanoacrylate with successful hemostasis. Obliteration was achieved in 25 (75.8%). Four patients died and one for failure of control bleeding. A high severity of Child-Pugh classification was related to treatment endoscopic failure (p=0.034). The main complication was bleeding after the injection of cyanoacrylate. CONCLUSIONS: Our results support the use of cyanoacrylate in the treatment of gastric varices with few major complications.

ABSTRACT

OBJETIVO: Avaliar a utilização do etil-2-cianoacrilato no tratamento de uma lesão provocada em um segmento parcialmente excluso do intestino do rato: o ceco. MÉTODOS: Utilizaram-se 45 ratos machos da linhagem Wistar, distribuidos em três grupos iguais, sendo que foi realizada a ressecção parcial do ceco. Os grupos foram denominados como: Grupo 1: a lesão foi tratada com aplicação de etil-2-cianoacrilato; Grupo 2: sutura e aplicação de etil-2-cianoacrilato; Grupo 3: sutura em bolsa. Os animais foram acompanhados no pós-operatório e metade de cada grupo foi necropsiada no 14º e restante no 28º pós-operatório. Dessa forma, foram submetidos à avaliação macroscópica, sendo coletadas amostras do ceco para avaliação histológica e, por fim, realizou-se a análise estatística RESULTADOS: O ganho de peso pós-experimento foi diferente nos grupos (p=0,028). A presença de microabcessos foi maior no 28º dia de pós-operatório no grupo 2, em comparação com o grupo 3 (p=0,003). A deposição de colágeno no 28º dia de pós-operatório foi maior no grupo 1 (p=0,036) e a intensidade da inflamação no 14º dia de pós-operatório foi maior no grupo 1 (p=0,045). Nos demais parâmetros avaliados, não ocorreu diferença estatística. CONCLUSÃO: A utilização do etil-2-cianoacrilato foi efetiva no tratamento do coto cecal excluso de ratos frente à avaliação macroscópica, microscópica e evolução pós-operatória.


OBJECTIVE: To evaluate the use of ethyl-2-cyanoacrylate in the treatment of an injury caused in a partially excluded segment of the mouse gut: the cecum. METHODS: We used 45 male Wistar rats, divided into three equal groups; in all there was performed a partial resection of the cecum. The groups were designated as Group 1: the lesion was treated with application of ethyl-2-cyanoacrylate, Group 2: suture and application of ethyl-2-cyanoacrylate, Group 3: purse-string suture. The animals were monitored postoperatively and half of each group was necropsied 14 days after the procedure, the remaining on the 28th. They were subjected to macroscopic evaluation, had cecal samples collected for histological examination and the findings were submitted to statistical analysis. RESULTS: Weight gain after the experiment was different among groups (p=0.028). The presence of microabscesses was higher at 28 days postoperatively in group 2 when compared to group 3 (p=0.003). The collagen deposition on the 28th postoperative day was greater in group 1 (p=0.036) and intensity of inflammation at the 14th postoperative day was greater in group 1 (p=0.045). In the other parameters there was no statistical difference. CONCLUSION: The use of ethyl-2-cyanoacrylate was effective in the treatment of cecal stump exclusion of rats as for macroscopic and microscopic findings and postoperative outcome.

ABSTRACT

Os objetivos do presente trabalho foram avaliar se o Super Bonder" apresenta algum risco de veiculação de microorganismos em humanos e se possui alguma atividade bactericida ou bacteriostática para cocos gram-positivo. Foi testada a esterilidade de dez tubas do adesivo nos meios de cultivo BHI, agar sangue, agar Sabouraud com cloranfenicol e Mycosel. A provável ação bactericida ou bacteriostática do adesivo Super Bonder"', in vitro, foi verificada utilizando cepas de Staphylococcus aureus e staphylococcus epidermidir, semeadas em meio de cultura agar sangue e agar Mueller-Hinton. Nao foi observado crescimento de microrganismos nos meios de cultura contendo somente gotas de Super Bonder"'. No agar sangue, observou-se ausência de beta-hemólise e de crescimento bacteriano nas áreas de sobreposição do adesivo. Em agarMueller-Hinton, houve rarefação de colônias ao redor das gotas do cianoacrilato.Os dados deste trabalho mostram que a cola de cianoacrilato Super Bonder"' parece ser livre de contaminação por microrganismos e apresenta possfvel atividade bacteriostatica in vitro.


The purposes of the present study were to verify the human's risk of the Super Bondet microorganisms' diffusion and the probably biocide or bacteriostatic adhesive's activity for gram-positive cocci. The sterility of ten tubes of the adhesive was tested in BHI culture tube and blood-agar, agar-Sabouraud with cloranfenicol and Mycosel culture plates. The biocide or bacteriostatic activity of the Super Bondet adhesive, in vitro, was verified using cultures of Staphylococcus aureus and staphylococcus epidermidis,seeded on blood-agar and agar-Mueller-Hinton culture plates. No microorganisms' growth was observed in the culture plates containing only drops of the Super Bondet. In agar-Mueller-Hinton, zones with reduced number of colonies were noticed around the cyanoacrylate's drops. In blood-agar, absence of haemolysis-beta and bacterial growth were observed in the covered areas of the adhesive. According to the results of this investigation, the Super Bondet cyanoacrylate is free of microorganisms' diffusion and probably inhibits in vitro the bacterial growth.

ABSTRACT

The use of ethyl-cyanoacrylate and octyl-cyanoacrylate were clinically and histopathologically compared on the corneas of 36 rabbits after lamellar keratectomy (standardized diameter and depth). The animals were distributed into two groups, one for each type of adhesive. From each group, six subgroups were histopathologically evaluated on the 3rd, 7th, 14th, 21st, 30th, and 60th day post-operative. General (daily) and ophthalmic (days 0, 1, 3, 5, 7, 14, 21, 30, 44, and 60) evaluations clinically indicated that there were significant differences for the variables water intake, attitude, blepharitis, corneal edema, and fluorescein test. The adhesive permanence time for octyl-cyanoacrylate (17.22 days) was greater than that for ethyl-cyanoacrylate (7.66 days). With respect to the histopathological evaluation, corneal epithelization and collagen organization occurred without severe complications. However, treatment with ethyl-cyanoacrylate led to a moderate inflammatory reaction in the initial phases. With octyl-cyanoacrylate, re-epithelization and collagen organization proceeded more slowly with a discrete inflammatory reaction in the initial phases. From clinical and histopathologic points of view, octyl-cyanoacrylate showed advantages over ethyl-cyanoacrylate, whereas wound healing was achieved in both groups without major complications.


Comparou-se o uso do etil-cianoacrilato e do octil-cianoacrilato em córneas de 36 coelhos após ceratectomia lamelar (diâmetro e profundidade padronizados). Os animais foram distribuídos em dois grupos, segundo o tipo de adesivo, e redistribuídos em seis subgrupos com três animais cada, para as avaliações histológicas aos 3, 7, 14, 21, 30 e 60 dias de pós-operatório. As avaliações clínicas gerais (diárias) e as oftálmicas (dias 0, 1, 3, 5, 7, 14, 21, 30, 44 e 60), indicaram diferença entre os dois grupos, quanto ao consumo de água, atitude, blefarite, edema da córnea e teste da fluoresceína. O Tempo de permanência, sobre o leito corneal, do adesivo octil-cianoacrilato (17,22 dias), foi maior que o do etil-cianoacrulato (7,66 dias). A histopatologia, para ambos os grupos, mostrou que a re-epitelização e a organização do colágeno ocorreram sem graves intercorrências. O grupo tratado com o etil-cianoacrilato apresentou, nas fases iniciais, reação inflamatória mais evidente que o tratado com octil-cianoacrilato. Neste, a re-epitelização e a organização do colágeno ocorreram mais lentamente e com reação inflamatória discreta. Sob os pontos de vista clínico e de avaliação histológica simples, os resultados mostraram vantagens do octil-cianoacrilato, entretanto, a cicatrização da córnea ocorreu em ambos os grupos.
