ABSTRACT
A descorna cirúrgica a campo ainda e uma prática comum em animais de produção, apesar deste procedimento na maioria ainda se realizado por leigos, ou realizada em animais com menos de um ano de idade com ferro candente (avermelhado), esta conduta geralmente é efetuada na propriedade, sendo executada pelo próprio proprietário ou funcionário. O presente experimento usando anestesia geral e bloqueio local do nervo córneo e circularmente na base do corno com abraçadeira de naylon para sutura de pele, associada a ligadura da artéria e veia cornual mostrou ser eficiente reduzindo o tempo cirúrgico a campo e promovendo uma prevenção antecipada de hemorragia que é frequente para este procedimento.(AU)
The surgical dehorning the field and still a common practice in farm animals, although this procedure in most still held by lay people, or performed on animals less than one year old with red-hot iron (red), this conduct is usually done on the property, being executed by the owner himself or employee. This experiment using general anesthesia and local lock of corneal nerve and round the horn base with clamp naylon for skin suture, associated with ligature of the artery and vein cornual is efficient by reducing surgical time field and promoting an early prevention of bleeding is frequent for this procedure.(AU)
El quirúrgica descorne el campo quieto y una práctica común en los animales de granja, aunque este procedimiento en la mayoría todavía en manos de los laicos, o lleva a cabo en animales de menos de un año de edad con hierro al rojo vivo (rojo), este comportamiento se realiza generalmente en la propiedad, los trabajos realizados por el propietario o el propio empleado. Este experimento usando anestesia bloques general y local de los nervios de la córnea y alrededor de la base del cuerno con naylon pinza de sutura de la piel, asociados con la ligadura de la vena y la arteria cornual fue eficiente que reduce el tiempo quirúrgico el campo y la promoción de una prevención temprana sangrado que es común para este procedimiento.(AU)

Introdução: Cicatrização de ferida é um processo bem organizado que tem como finalidade a reparação tecidual completa. Colas e adesivos tópicos oferecem uma alternativa não invasiva, de retirada fácil e espontânea; boa força tênsil; menor tempo de aplicação, sendo o Prineo® uma cola adesiva associada a uma malha de poliéster aplicados sobre a ferida. Método: Trata-se de um estudo transversal retrospectivo com análise de 101 procedimentos cirúrgicos no período de 2012 a 2014, nos quais a síntese da ferida operatória ocorreu com fios cirúrgicos de náilon ou Prineo®, sendo aplicada análise estatística. Resultados: Neste estudo, seis pacientes apresentaram dermatite de contato ao uso do Prineo® com significância estatística (p = 0,042). O uso desse sistema diminuiu a taxa de alargamento cicatricial (p < 0,05). O presente trabalho não apresentou diferença estatística (p = 0,068) na qualidade da cicatriz entre os pacientes que utilizaram Prineo® em relação ao grupo controle, demonstrando que em ambos os grupos o resultado cicatricial foi de excelente (87%) a bom (27%) na sua maioria. Conclusão: Conclui-se no estudo que os pacientes que utilizaram o sistema de octil-2-cianocrilato associado a malha, Prineo®, apresentaram menores índices de alargamento cicatricial, dependentes de uma espessura de derme satisfatória, e maiores taxas de dermatites por contato em relação àqueles em que a ferida foi encerrada com fios cirúrgicos. Os dois grupos demonstraram qualidades cicatriciais excelentes a bons, sem diferença estatística em tais resultados estéticos cicatriciais.
Introduction: Wound healing is a well-organized, directed process of tissue repair. The process can be expedited using topical glues and adhesives, which offer a non-invasive, easily removable alternative to suturing. Furthermore, such products have good tensile strength and involve lower application time. In particular, the Prineo® adhesive is applied to a polyester mesh that covers the wound. Method: We carried out a retrospective, cross-sectional study, with subsequent statistical analysis , involving 101 surgical procedures in which wound closure was performed using either nylon sutures or Prineo®. All the procedures were performed between 2012 and 2014. Results: Six patients had contact dermatitis after Prineo® was used, with statistical significance (p = 0.042). Furthermore, Prineo® decreased the rate of scar enlargement (p < 0.05) . There was no statistical difference between the Prineo® and suture groups in terms of scar quality (p = 0.068); in both groups, the scar result was mostly excellent (87 %) to good (27%). Conclusion: Patients whose wounds were closed using Prineo® a system involving octyl-2-cyanoacrylate and an associated polyester mesh displayed lower rates of scar enlargement, which depended on whether the thickness of the dermis was satisfactory. However, the same patients had higher rates of contact dermatitis than those whose wounds were closed using surgical sutures. Both groups showed excellent to good scar quality, with no significant difference in terms of esthetic scar results.

Introdução - As suturas têm um papel importante na maioria das cirurgias, podendo influenciar grandemente no resultado clínico final. A escolha do fio de sutura constitui-se em um dos fundamentos para se obter a menor reação inflamatória tecidual quando do processo de reparação, já que alguns fios são considerados inertes, provocando menor reação do que outros. Materiais e Métodos - Foram utilizados quatro diferentes fios de sutura, a saber : seda, nylon, poliglactina 910 (Vicryl) e politetrafluoretileno expandido (e-PTFE). Os fios de sutura foram colocados em gengivas humanas as quais seriam submetidas a cirurgias pré-protéticas. Após sete dias, o tecido gengival foi excisado e processado histologicamente para observação em microscopia óptica. Resultados e Conclusão - Os resultados permitiram chegar à conclusão que o fio que promoveu menor reação foi o de poliglactina, seguido pelos de e-PTFE e nylon, culminando com a seda que provocou maior inflamação.
Introduction - The sutures play an important role in most of the surgeries, and may greatly influence the final clinical result. The choice of the suture material consists of one of the basis to obtain the least tissular inflammatory reaction at the time of healing process, since some materials are considered inert promoting less reaction than others. Materials and Method - It was evaluated the gingival reaction using four different suture materials such as: silk, nylon, polyglactin 910 (Vicryl) and expanded polytetrafluorethylene (e-PTFE). The suture materials were placed in human gingiva that would be to preprosthetics surgeries. After seven days, the gingival tissue was excised and histologically processed for optical microscopy. Results and Conclusion - The results show that the suture which promoted the least reaction was the polyglactin, followed by e-PTFE, nylon and silk which promoted the highest inflammation.

PURPOSE: The aim of this experimental study was to evaluate through a clinical and histopathological analysis the tissue reactivity caused by two monofilament sutures nylon and poliglecaprone 25 on the internal and external sutures in rats. METHODS: For this study, we used forty male Rattus novergicus (Wistar rats). The experimental procedures were incisions and divulsions performed on the back of the animals' thighs. Internal and external sutures were done on the right thigh using nylon 0-5, and on the left thigh using poliglecaprone 25 0-5. The animals were distributed in 4 groups of 10 rats, according postoperatory period on the 7, 14, 21 and 28 days, G1 (7th day), G2 (14th day), G3 (21th day) and G4 (28th day). The clinical assessment aimed to verify the existence of dehiscence, exsudate and edema. The histopathologic analysis was intended to evaluate the inflammatory reaction, foreign body giant cells, fibroblastic proliferation and fibrosis. RESULTS: Clinically, no changes were found on groups studied. Histopathological analysis inflammatory reaction, foreign body giant cells, fibroblastic proliferation and fibrosis were higher on the internal sutures with nylon. On the sutures done with poliglecaprone 25 showed an increase in tissue reactivity passing postoperatory period. CONCLUSIONS: On the basis of the methodology used in the study, it was concluded that external sutures done with nylon produce less tissue reactivity; on internal sutures, however, this material contributes to the maintenance of the tissue reaction. The external sutures done with poliglecaprone 25 showed a greater tissue reaction; on the external sutures the tissue reaction decreased while the thread was being absorbed.

OBJETIVOS: Neste estudo realizamos a análise clínica e histopatológica da reacão tecidual dos fios de nylon e poliglecaprone 25 monofilamentares nas suturas interna e externa em ratos. MÉTODOS: Foram utilizados 40 Rattus norvegicus (Wistar) machos. O ato operatório consistiu de incisão e divulsão dos planos muscular e cutâneo realizadas na região posterior das coxas dos animais. As suturas internas e externas da coxa direita foram realizadas com o fio de nylon nº5-0, e na coxa esquerda aplicamos o poliglecaprone 25 nº5-0. Os animais foram divididos em 4 grupos (n=10) de acordo com o tempo pós-operatório G1 (7 dias), G2 (14 dias), G3 (21 dias) e G4 (28 dias). Para a avaliacão cínica foi considerada a ocorrência de deiscência, de exsudato e edema. Na análise histopatológica objetivou-se avaliar reacão inflamatória, células gigantes de corpo estranho, proliferacão fibroblástica e fibrose. RESULTADOS: Clinicamente, não foram observadas alteracões nos grupos estudados. Histopatologicamente a reacão inflamatória, presenca de células gigantes de corpo estranho, proliferacão fibroblástica e fibrose foram maiores nas suturas internas realizadas com Nylon. Nas suturas realizadas com poliglecaprone 25 essa reacão declinou com o passar do tempo pós-operatório. CONCLUSAO: De acordo com a metodologia empregada podemos concluir que as suturas externas realizadas com nylon induziram menor reacão tecidual, enquanto que nas suturas internas este fio contribuiu para perpetuar a reacão tecidual. As suturas externas realizadas com poliglecaprone 25 apresentaram maior reacão tecidual, e suturas internas realizadas com o mesmo fio a reacão tecidual declinou na medida em que o fio estava sendo absorvido.

The gingival reaction to 4 different suture materials used in periodontal surgery was studied in 36 patients. The gingiva was sutured prior to surgery and biopsies were taken at 3, 7 and 14 days to observe the tissue reaction. The histological examination showed that silk caused the most intense and longest inflammatory response. Polyester and perlon provoked shorter, less intense tissue reactions than silk, and nylon caused the least inflammatory response, with earlier tissue repair.
