Oral or topical administration of L-arginine changes the expression of TGF and iNOS and results in early wounds healing

ABSTRACT PURPOSE: To evaluate the contribution of L-arginine oral or topical rout of administration in the surgical wound healing process. METHODS: L-arginine was orally or topically administrated to mice after a laparotomy model procedure. The wounds were analyzed to evaluate the granulation tissue by HE analysis, collagen deposition, iNOS and cytokines production by immunochemisyry on wound progress. Mice used in this model were healthy, immunosupressed or diabetic and all of them were treated with different concentration of L-arginine and rout of administration. RESULTS: Suggested that groups treated with L-arginine orally or topically improved wound repair when compared with non-treatad mice. L- arginine treatment stimulated TGF-β and restricted NO production leading to a mild Th1 response and collagen deposition in injured area, when it was orally administrated. Topical administration decreased IL-8 and CCR1 expression by wound cells but did not interfere with TNF-α and IL-10 production, ratifying the decrease of inflammatory response, the oral administration however, presented a higher iNOS and TGF-β expression then. L-arginine treatment also improved the improved the wound healing in immunosupressed or diabetic mice. CONCLUSION: L-arginine administrated orally or topically can be considered an important factor in the recuperation of tissues.

Carcinoma triquilemal, um tumor incomum: atualização sobre manejo e prognóstico / Trichilemmal carcinoma, an uncommon tumor: update on its management and prognosis

INTRODUÇÃO: O carcinoma triquilemal (CT) é uma neoplasia rara dos anexos cutâneos. Foi descrito pela primeira vez em 1968, como tricoleptocarcinoma, e tem incidência de 0,05% em pacientes submetidos a exame histopatológico após excisão de lesões cutâneas. Parece ser um tumor de baixa agressividade, porém, relatos na literatura colocam em dúvida tal comportamento indolente. OBJETIVOS: Oferecer uma atualização sobre manejo e prognóstico do CT. MÉTODOS: Pesquisa no PubMed e SciELO com os termos MeSH "trichilemmal carcinoma", "tricholemmal carcinoma", "adnexal skin tumor", "carcinoma triquilemal". RESULTADOS: Devido a sua raridade, a maior parte da literatura se baseia em relatos de caso, os quais na sua maioria corroboram a natureza indolente da doença. Excisão cirúrgica é o tratamento preconizado, com baixo risco de recidiva e baixa morbimortalidade. CONCLUSÃO: O comportamento da lesão e as condutas no tratamento do CT baseiam-se em casos isolados ou de pequenas séries de casos. Devido a sua baixa prevalência, uma colaboração multicêntrica agrupando um maior número de casos pode ajudar a definir melhor recomendações de tratamento, fisiopatologia e prognóstico. Excisão cirúrgica continua a ser o padrão-ouro de tratamento, com baixo risco de recidiva.

INTRODUCTION: Trichilemmal carcinoma (TC) is a rare neoplasm of skin appendages. It was first described in 1968 as tricoleptocarcinoma, and has an incidence of 0.05% in patients subjected to histopathological examination after excision of cutaneous lesions. TC has an indolent clinical course ; however, reports in the literature put in doubt this indolent behavior. OBJECTIVES: To provide an update on the management and prognosis of TC. METHODS:A search of the PubMed and SciELO databases by using with the MeSH terms "trichilemmal carcinoma", "tricholemmal carcinoma", "adnexal skin tumor", and "carcinoma triquilemal" was performed. RESULTS: Owing to the rarity of TC, most studies were case reports, which essentially corroborate the indolent nature of the disease. Surgical excision is the recommended treatment, and is associated with a low risk of recurrence and low morbidity and mortality. CONCLUSION: The behavior of the lesion and the procedure of treatment of TC are based on isolated cases or in a small series of cases. Because of its low prevalence, a multicenter collaboration of a greater number of cases can help define the best treatment recommendations, pathophysiology, and prognosis. Surgical excision remains the gold standard of treatment, and is associated with a low risk of recurrence.

Reconstrução nasal: análise de série de casos / Nasal reconstruction: an analysis of a series of cases

INTRODUÇÃO: A reconstrução nasal é desafiadora devido à posição central e proeminente do nariz na face. Pequenos defeitos nessa região tornam-se óbvios. Análise retrospectiva das 146 cirurgias de reconstrução nasal nos Serviços Integrados de Cirurgia Plástica do Hospital Ipiranga - SICPHI, avaliando a incidência dos defeitos nasais, assim como as principais técnicas cirúrgicas realizadas de acordo com cada região nasal. MÉTODOS: Estudo descritivo retrospectivo pela revisão de 109 prontuários e arquivos fotográficos, dos pacientes atendidos nos Serviços Integrados de Cirurgia Plástica do Hospital Ipiranga, em São Paulo, SP, no período compreendido entre janeiro de 2011 a junho de 2014. RESULTADOS: Foram realizadas 146 cirurgias. A faixa etária média foi de 67 anos. Em relação ao tipo de tumores malignos encontrados, 104 (73%) eram carcinoma basocelular e três (2%) carcinoma espinocelular. As 36 (25%) lesões restantes eram de características benignas. As regiões nasais mais acometidas foram: asa nasal, 55 (38%); dorso, 36 (25%); ponta, 26 (18%); lateral, 12 (8%); não especificada, sete (5%); comprometimento total do nariz, cinco (3%); e columela, dois (1%). Observou-se a preferência ao fechamento primário dos defeitos. No caso de impossibilidade do mesmo, realizaram-se retalhos locais, concordando com a literatura. CONCLUSÃO: As subunidades estéticas nasais podem ser reconstruídas por uma variabilidade de técnicas cirúrgicas. O cirurgião deve buscar um adequado resultado estético e funcional.

INTRODUCTION: Nasal reconstruction is challenging because of the central position and role of the nose in the face. Minor defects in this region become obvious. A retrospective analysis of 146 nasal reconstruction surgeries in the Integrated Plastic Surgery Services of the Ipiranga Hospital (SICP-HI) was performed, evaluating the incidence of nasal defects, as well as the main surgical techniques performed in accordance with each nasal region. METHODS: A retrospective descriptive study through a review of 109 medical records and photograph archives of patients treated in SICP-HI, São Paulo, SP, from January 2011 to June 2014. RESULTS: A total of 146 surgeries were performed. The mean patient age was 67 years. Regarding the type of malignant tumors found, 104 (73%) were basal cell carcinoma and 3 (2%) were squamous cell carcinoma. The remaining 36 (25%) lesions were benign. The most affected nasal regions were as follows: nasal wing, 55 (38%); the dorsum, 36 (25%); tip, 26 (18%); sidewalls, 12 (8%); unspecified, 7 (5%); total involvement of the nose, 5 (3%); and the columella, 2 (1%). There was a preference for primary closure of the defect. However, if this was infeasible, local flaps were used, in agreement with the literature. CONCLUSION: The nasal aesthetic subunits can be reconstructed using a variety of surgical techniques. The surgeon should seek an appropriate aesthetic and functional outcome.

Pioderma gangrenoso após quadrantectomia de mama com radioterapia intraoperatória: relato de caso / Pyoderma gangrenosum after quadrantectomy with intraoperative radiotherapy: a case report

Pioderma gangrenoso é uma doença inflamatória imunomediada e rara da pele, de diagnóstico extremamente desafiador. A evolução clínica é a base para o diagnóstico, cursando com lesões pustulosas superficiais, halo eritematoso doloroso, rápida progressão para ulcerações dolorosas e estéreis, sem resposta a antibióticos ou a novas intervenções cirúrgicas e, finalmente, com pronta melhora com uso de imunossupressores. O atraso no diagnóstico pode acarretar numerosas internações e terapias prolongadas, sendo que seu reconhecimento precoce, por outro lado, evita a progressão dessas ulcerações e sua morbidade. Relatou-se um caso de pioderma gangrenoso que evoluiu após cirurgia associada à radioterapia intraoperatória no tratamento conservador do câncer de mama, fazendo-se uma revisão de casos relatados na literatura e suas possibilidades terapêuticas. Questiona-se, também, se a radioterapia intraoperatória estaria relacionada com algum estímulo imunomediado, o que poderia ter facilitado o desencadeamento do quadro.

Pyoderma gangrenosum is an immune-mediated inflammatory and rare skin disease with an extremely challenging diagnosis. The clinical evolution of the disease is the basis for the diagnosis that involves pustular superficial lesions, painful erythematous halo, rapid progression to painful and sterile ulcerations, unresponsiveness to antibiotics or new surgical interventions, and finally, ready improvement with the use of immunosuppressive drugs. Delayed diagnosis may cause numerous hospitalizations and prolonged therapy, whereas early recognition can prevent the progression of the ulcerations and their morbidities. We report a case of pyoderma gangrenosum that evolved after surgery and was associated with intraoperative radiotherapy for the conservative treatment of breast cancer. In addition, we reviewed reported cases in the literature and therapeutic options. It is conjectured that intraoperative radiotherapy might be related to some immune-mediated stimuli that could trigger the clinical condition.

Análise do atendimento clínico de portadores de úlceras crônicas em membros inferiores / Analysis of the clinical care of patients with chronic ulcers of the lower limbs

Introdução: Úlceras crônicas em membros inferiores podem apresentar diferentes etiologias, sendo as mais frequentes: venosa, arterial, traumática, infecciosa e diabética. O tratamento dessas feridas é dinâmico e depende da evolução da reparação tecidual. Esse tratamento inclui métodos clínicos e cirúrgicos, sendo o curativo o método não cirúrgico mais frequentemente utilizado. Curativos podem ser desde de coberturas inertes até veículos para atuação de princípios ativos no leito da ferida. A principal indicação de ativos está relacionada a efeitos de desbridamento e controle da população bacteriana, possibilitando o preparo desses leitos para resolução cirúrgica ou espontânea. Método: Esse estudo é observacional, longitudinal, retrospectivo, de amostra randomizada no qual pretendemos analisar o atendimento prestado aos portadores de úlceras crônicas em membros inferiores no Ambulatório de Feridas Crônicas da Divisão de Cirurgia Plástica do HCFMUSP entre 2011 e 2013. Resultados: Foram analisados prontuários de indivíduos de ambos os gêneros, idade média 60 anos, portadores de úlceras crônicas em diferentes estágios evolutivos. Foram pesquisadas comorbidades, doença de base, tamanho da lesão, tratamentos utilizados e evolução das feridas. Notouse predomínio das causas vasculares (69,2%) como doenças de base. Todos os pacientes foram primeiramente tratados com curativos contendo princípios ativos, para preparo do leito das feridas. Desses, 84% foram encaminhados para resolução cirúrgica das feridas. Houve fechamento espontâneo em 1,5% dos casos. Os demais pacientes (14,5%) apresentaram piora das lesões com tratamento tópico, necessitando outras formas de preparo desse leito. Conclusão: Agentes tópicos podem ser uma forma ambulatorial/domiciliar efetiva de preparo do leito de úlceras crônicas para resolução cirúrgica.

Introduction: Chronic ulcers of the lower limbs may have different etiologies, with the most frequent being venous, arterial, traumatic, infectious, and diabetic. The treatment of these wounds is dynamic and depends on the evolution of tissue repair. This treatment includes clinical and surgical methods, and dressings are the most frequently used. Dressings can range from inert covers to vehicles for actuation of active substances in the wound bed. The main indication for these substances is related to the effects of debridement and control of the bacterial population, enabling the preparation of wound beds for surgical or spontaneous resolution. Method: This study is an observational, cross-sectional, retrospective study, with random sampling, aimed at assessing the care provided to patients with chronic ulcers of the lower limbs in the Outpatient Clinic for chronic wounds of the Plastic Surgery Division, HCFMUSP, between 2011 and 2013. Results: The clinical charts of 481 patients of both sexes, with a mean age 60 years, were analyzed; all had chronic ulcers in different stages of evolution. Comorbidities, underlying disease, size of the lesion, treatments, and evolution of wounds were evaluated. A predominance of vascular disease (69.2%) was the underlying cause. All patients were initially treated with dressings containing active agents, for preparation of the wound bed. Of these, 84% were referred for surgical management of wounds. There was no spontaneous closure in 1.5% of cases. The remaining patients (14.5%) showed worsening of lesions with topical treatment, and required other forms of preparation of the wound bed. Conclusion: Topical agents may be an effective outpatient/home method to prepare the wound bed of chronic ulcers for surgical management.

Ressecção alargada no tratamento do dermatofibrossarcoma protuberante / Extended resection for treatment of dermatofibrosarcoma protuberans

INTRODUÇÃO: Dermatofibrossarcoma Protuberante (DFSP) é um tumor de pele raro e de malignidade intermediária, com baixo potencial metastático, mas alta taxa de recorrência após tratamento cirúrgico. O tratamento clássico é a ressecção alargada, com margens variáveis. Muitos trabalhos descreveram os resultados da cirurgia micrográfica de Mohs no tratamento desta afecção. O objetivo deste estudo retrospectivo é verificar se a ressecção alargada constitui um método confiável no tratamento do DFSP. MÉTODO: Entre agosto de 1968 e setembro de 2013, 31 lesões foram ressecadas em 30 pacientes com DFSP. Todos os pacientes foram submetidos à excisão cirúrgica radical, com remoção de 3 cm de tecido sadio nas margens laterais e com a margem profunda incluindo uma estrutura anatômica não infiltrada pelo tumor. Os seguintes aspectos foram estudados: gênero, idade, local da lesão, tratamento prévio e características peculiares da proservação. RESULTADOS: Dezenove (63,3%) pacientes eram do sexo masculino e 11 (37,7%), do feminino. A média de idade da apresentação foi de 40,9 anos. As lesões estavam localizadas em tronco (61,3%), cabeça (22,6%), membros superiores (6,4%), membros inferiores (6,4%) e pescoço (3,3%). Tratamento prévio não foi observado em 58,1% dos pacientes. Um paciente (3,3%) evoluiu com recidivas e óbito, em decorrência do tratamento cirúrgico; três (10,0%) faleceram por outras causas. CONCLUSÕES: A ressecção alargada com margens de 3 cm, com remoção de estrutura anatômica sadia, constitui método eficiente no tratamento do DFSP.

INTRODUCTION: Dermatofibrosarcoma protuberans (DFSP) is a rare skin tumor with intermediate malignancy and low metastatic potential, but a high recurrence rate after surgical treatment. The classical treatment is extended resection with varying margins. Many studies have described Mohs micrographic surgery for treatment of this disease. This retrospective study was to verify if extended resection is a reliable DFSP treatment method. METHOD: A total of 31 lesions were resected in 30 patients with DFSP between August 1968 and September 2013. All patients underwent radical surgical excision, with removal of 3 cm of healthy tissue on the lateral margins and with deep margin including an anatomical structure without tumor infiltration. Analyzed patient characteristics included sex, age, tumor site, previous treatment, and peculiar characteristics observed during the follow-up period. RESULTS: Nineteen (63.3%) patients were male and 11 (37.7%) female. Their average age at tumor presentation was 40.9 years. The tumors were located on the trunk (61.3%), head (226%), upper limbs (6.4%), lower limbs (6.4%), and neck (3.3%). No previous treatment was reported in 58.1% of the patients. One patient (3.3%) developed recurrence and died due to the surgical treatment; three patients (10.0%) died from other causes. CONCLUSIONS: Extended resection with 3-cm margins and removal of healthy anatomical structures is an effective treatment for DFSP.

Fibromatose digital infantil: relato de caso / Infantile digital fibromatosis: case report

Introdução: A fibromatose digital infantil é uma proliferação nodular, assintomática, rara e benigna do tecido fibroso, que ocorre quase exclusivamente na região dorsal e lateral dos dedos das mãos e pés. O artigo relata um caso de fibromatose digital infantil, também conhecida como tumor de Reye. Relato de Caso: Trata-se de um caso diagnosticado por meio de exames clínico, de imagem e histopatológico. O paciente apresentou-se ao Setor de Ortopedia do Hospital, queixando-se de uma lesão nodular, eritematosa, indolor, no segundo pododáctilo do pé esquerdo, existente havia quatro anos. Durante o exame físico, notava-se uma deformidade no II pododáctilo, causada por uma lesão nodular, eritematosa, indolor, de aproximadamente 1,5 cm, que não acarretava alterações funcionais. O exame de ultrassom revelou a presença de uma imagem nodular sólida, hipoecogênica, envolvendo o tendão do extensor do II pododáctilo na falange média. O diagnóstico inicial era de fibroma ou sinovioma. Pelas características clínicas da lesão, por seu tempo de evolução e pelos achados de imagem, a equipe optou por uma biópsia. No entanto, devido ao pequeno tamanho da lesão, sendo a biópsia aberta, realizou-se a exérese cirúrgica. O exame histopatológico confirmou o diagnóstico de fibromatose digital infantil. Conclusão: Esse tumor constitui uma entidade clínica rara, que deve ser diferenciada de outras lesões encontradas nos dedos das mãos e dos pés. O diagnóstico correto raramente é feito antes da operação, devido, principalmente, à falha em reconhecer essa entidade. Por essa razão, é essencial considerar essa lesão em diagnósticos diferenciais.

Introduction: Infantile digital fibromatosis, also known as Reye tumor, is a rare, asymptomatic, benign nodular proliferation of fibrous tissue, which occurs almost exclusively in the dorsolateral region of the fingers and toes. This article reports a case of infantile digital fibromatosis. Case report: This case was diagnosed by clinical, imaging, and histopathological examination. The patient presented at the rthopedic Department of our hospital, with a 4-year history of a painless, erythematous nodular lesion on the econd toe of the left foot. On physical examination, a deformity of the second toe caused by a nodular, erythematous, painless lesion of approximately 1.5 cm diameter was noted; the lesion did not result in functional changes. Ultrasound examination revealed a solid, hypoechoic nodule involving the extensor tendon in the middle phalanx of the second toe. The initial diagnosis was fibroma or synovioma. Due to the clinical characteristics of the lesion, its evolution, and the imaging findings, the team chose to perform a biopsy. However, due to the small size of the lesion, upon open biopsy, surgical excision was performed. Histopathological examination confirmed the diagnosis of infantile digital fibromatosis. Conclusion: Infantile digital fibromatosis is a rare clinical entity, which should be differentiated from other lesions found in the fingers and toes. The correct diagnosis is rarely made pre-operatively, due mainly to a failure to recognize this entity. For this reason, it is essential to onsider this lesion in the differential diagnosis of digital nodules.

Calcanectomia subtotal para tratamento de úlcera de pressão com osteomielite associada: relato de 2 casos / Subtotal calcanectomy for the treatment of calcaneal pressure sores with associated osteomyelitis: a report of 2 cases

Introdução: Feridas em pés são muito frequentes e requerem abordagem multidisciplinar para a sua prevenção, tratamento e reabilitação. Quando acometem o calcâneo, oferecem dificuldade ainda maior e podem apresentar complicação com a ocorrência de osteomielite. Debridamento de tecido desvitalizado e antibioticoterapia são etapas obrigatórias para o tratamento. Na reconstrução, retalhos locais ou livres são necessários. Porém, nem todos os pacientes, devido a condições sistêmicas ou de vascularização local, são candidatos a esse tipo de reconstrução e acabam sendo submetidos a amputações. Relato de caso: Os autores relatam dois casos nos quais foram utilizadas calcanectomias subtotais para o tratamento de feridas em calcâneo. Em ambos os casos, foram evitadas as amputações.

Introduction: Feet wounds are very common and require multidisciplinary approach for prevention, treatment and rehabilitation. When involving the calcaneus, they offer even greater difficulty and may complicate with osteomyelitis. Debridement of devitalized tissue and antibiotics are important steps for treatment. For the reconstruction, local or free flaps are needed. However, not all patients, due to systemic conditions or local blood supply, are not candidates for this type of reconstruction and some times are submitted to amputations. Cases Report: The authors report two cases in which subtotals calcanectomies were used for the treatment of wounds in the calcaneus. In both cases, amputations were avoided.

Mechanical asphyxia and mechanical injury were the two most common causes of death in these cases.@*CONCLUSION@#The social characteristics of suspects, criminal motivation, injury instruments, distribution of injuries, cause of death, and manner of death in Suzhou showed similar general characteristics as the experience for detecting homicide cases in the future.

Do stem cells promote healing of experimentally induced wound injury in adult male dogs? Histological and immunohistochemical study

Background: Stem cells have generated considerable interest and promise as a potential source of cells for cell-based therapeutic strategies, primarily owing to their intrinsic ability to self-renew and differentiate into multiple functional cell types. Stem cells have been utilized to regenerate viable skin tissue

Aim of the work: The present study was carried out to investigate the healing capacity of autologous bone marrow-derived mesenchymal stem cells [BM-MSCs] and its regenerative role in experimentally induced wound injury

Materials and methods: The present study was carried out on 18 dogs. The study included two groups. Group I [n=6] was used a negative control and received no treatment. Group II was used as an experimental group and was divided into subgroup IIa [n=6], used as a positive control, and subgroup IIb [n=6]. Subsequently, three circular wounds were made using a 10-mm diameter skin punch biopsy in the animals of subgroup IIa and subgroup IIb to induce wound injury. Group IIb were injected subcutaneously with undifferentiated mesenchymal stem cells at a dose of 1.4-1.6×10[6]/ml in 5 ml sterile saline into the wound bed for 2 weeks after wound injury; skin biopsies from the wound areas were prepared for staining by H and E and immunostaining using anti-Thy-1 [CD90] antibodies

Results: BM-MSC-treated wounds showed accelerated wound closure, with increased re-epithelialization of the epidermis, increased dermal cellularity and hair follicles, and angiogenesis. This was confirmed by the apparent increased immunoreactivity of the cell content of anti-rat Thy-1 CD90 cells in the dermis

Conclusion: Asubcutaneous injection of autologous undifferentiated mesenchymal stem cells into the wound bed is an effective method of wound regeneration and can be used in chronic wounds as in a diabetic foot

Wound healing using ionic silver dressing and nonocrystalline silver dressing in rats / Cicatrização de feridas em ratos utilizando curativos com prata iônica e nanocristalina

PURPOSE: To investigate the results of the healing process on surgical wounds in the back of Wistar rats using nanocristaline and ionic silver dressing. METHODS: Sixty rats Wistar were submitted to surgical wounds with punch of 8mm in diameter. In 30 animals (groups PN - nanocristaline and AD - control) two surgical wounds were done diametrically opposite on the upper back side. On the right side was used nanocristaline (PN) silver dressing and on the left side, distilled water dressing (AD). On the other group of 30 rats, only one wound was made with the punch, on the right side, and was used ionic silver dressing. So, the groups were divided into three subgroups, according to the day of death (7th, 14th and 21st day). In each of these days the wounds diameter were measured to evaluate the wound contraction. Microscopic data were analyzed using the H&E staining to verify the inflammatory process and neovascularization. The Masson trichrome staining was used to verify the fibrosis. RESULTS: Macroscopically only the subgroup of 21st day showed statistical significance; between the groups AD and PI inflammatory process appeared in the 7th day subgroup in 90% of the cases. In neovascularization there was statistical significance between the groups PN and AD in the subgroup of 7th day. Fibrosis did not show statistical significance in the studied groups. CONCLUSIONS: In relation to wound contraction, PN and PI groups showed better results than the AD group. In regard to histological analysis, H&E staining showed that there was presence of inflammation in all groups, and at the end, the control group (AD) on 7th day, was superior to PN and PI groups. In relationship to fibrosis, no differences were obtained among groups.

OBJETIVO: Investigar os resultados da cicatrização de feridas cirúrgicas em dorso de ratos, utilizando curativos de prata nanocristalina e iônica. MÉTODOS: Sessenta ratos Wistar foram submetidos à feridas cirúrgicas com punch de 8mm de diâmetro. Foram confeccionadas duas lesões diametralmente opostas nos animais dos grupos prata nanocristalina (PN) e controle água destilada (AD). Na lesão do lado direito foi utilizado curativo com prata nanocristalina e na do lado esquerdo curativo com água destilada. No outro grupo de 30 ratos, apenas foi realizada uma lesão com o punch no lado esquerdo e curativo com prata iônica. Os grupos foram divididos em subgrupos conforme o dia da morte (7º, 14º e 21º dias), o que caracterizou a existência de três subgrupos, nos quais foram tomadas as medidas do centro das lesões para estudar macroscopicamente a contração da ferida Microscopicamente foi utilizada a coloração H&E, através da qual foi observado o processo inflamatório e a neovascularização. Com a coloração Tricômio de Masson, foi estudada a fibrose. RESULTADOS: Macroscopicamente apenas o subgrupo 21 dias apresentou significância estatística entre os grupos AD e prata iônica (PI), porém quando comparados os dias de avaliação, dois a dois, dentro de cada tratamento, todos os subgrupos apresentaram significância estatística (p<0,05). A variável intensidade da inflamação apresentou-se de forma acentuada no subgrupo sete dias em 90% dos casos, entre os grupos AD e PI. Na variável neovascularização houve significância estatística entre os grupos PN e AD no subgrupo sete dias. A variável fibrose não apresentou significância estatística nos subgrupos estudados. CONCLUSÕES: Em relação à contração da ferida, os grupos PN e PI apresentaram resultados superiores ao grupo AD. Com relação à análise histológica, na coloração H&E observou-se que houve presença de processo inflamatório nos grupos estudados sendo que, ao final, o grupo controle (AD) no 7º dia mostrou-se superior aos grupos PN e PI. Com relação à variável fibrose, não houve diferenças entre os grupos.
