Analysis of tissue inflammatory response, fibroplasia, and foreign body reaction between the polyglactin suture of abdominal aponeurosis in rats and the intraperitoneal implant of polypropylene, polypropylene/polyglecaprone and polyester/porcine collagen meshes

ABSTRACT Purpose To compare tissue inflammatory response, foreign body reaction, fibroplasia, and proportion of type I/III collagen between closure of abdominal wall aponeurosis using polyglactin suture and intraperitoneal implant of polypropylene, polypropylene/polyglecaprone, and polyester/porcine collagen meshes to repair defects in the abdominal wall of rats. Methods Forty Wistar rats were placed in four groups, ten animals each, for the intraperitoneal implant of polypropylene, polypropylene/polyglecaprone, and polyester/porcine collagen meshes or suture with polyglactin (sham) after creation of defect in the abdominal wall. Twenty-one days later, histological analysis was performed after staining with hematoxylin-eosin and picrosirius red. Results The groups with meshes had a higher inflammation score (p < 0.05) and higher number of gigantocytes (p < 0.05) than the sham group, which had a better fibroplasia with a higher proportion of type I/III collagen than the tissue separating meshes (p < 0.05). There were no statistically significant differences between the three groups with meshes. Conclusions The intraperitoneal implant of polypropylene/polyglecaprone and polyester/porcine collagen meshes determined a more intense tissue inflammatory response with exuberant foreign body reaction, immature fibroplasia and low tissue proportion of type I/III collagen compared to suture with polyglactin of abdominal aponeurosis. However, there were no significant differences in relation to the polypropylene mesh group.

Introducción: El trauma ocular es una causa importante de morbilidad oftalmológica en el mundo, con implicaciones socio-económicas importantes para el paciente y sus familiares, pues ocurre generalmente en adultos jóvenes, con una buena agudeza visual al inicio del evento traumático y que se verá comprometida según la severidad del trauma, las estructuras oculares que afecte y las complicaciones que puedan aparecer; de ahí que la pérdida de la visión sea una de las minusvalías más temidas. Presentación del caso: Paciente con alteraciones anatómicas y funcionales producidas por un trauma ocular a globo abierto penetrante zona 3, y presencia de cuerpo extraño intraocular vegetal, donde se logró un diagnóstico precoz y conducta quirúrgica oportuna obteniendo resultados visuales excelentes. Conclusiones: El trauma ocular a globo abierto penetrante zona III con cuerpo extraño intraocular vegetal, a pesar de su difícil manejo, permite alcanzar buenos resultados visuales. Esto depende del diagnóstico precoz, y una conducta pertinente basándose en criterios actuales del BETT Y del OTS(AU)

Introduction: Ocular trauma is a fundamental cause for ophthalmological morbidity worldwide, with important socio-economic implications for the patient and their relatives, since it usually occurs in young adults, with good visual acuity at the beginning of the traumatic event and which will be seen compromised based on trauma seriousness, the affected ocular structures and the complications that may appear; hence, vision loss is one of the most feared handicaps. Case presentation: Patient with anatomical and functional alterations produced by an ocular trauma in open penetrating globe zone III, and the presence of a vegetal intraocular foreign body, where an early diagnosis and timely surgical behavior were achieved, obtaining excellent visual results. Conclusions: Ocular trauma in open penetrating globe zone III with vegetal intraocular foreign body, in spite of its difficult management, allows to achieve good visual results. Based on current criteria, this depends on early diagnosis and relevant behavior based on current criteria(AU)

Tomar leche no siempre es bueno. .. un accidente que a todos nos puede suceder / Drinking milk is not always good ... ... an accident that can happen to all of us

En pacientes que se presentan con disfagia y/o odinofagia súbitas después de ingerir alimentos, debemos sospechar la ingestión de un cuerpo extraño. Los cuerpos extraños en esófago no siempre son visibles en una radiografía de cuello, por lo que debemos utilizar otros métodos diagnósticos como la tomografía axial computarizada y la gastroscopía. El presente caso ilustra la ingestión accidental del sello de un envase de leche.

In patients acute with dysphagia and/or odynophagia after ingestión of a meal, we should always suspect the ingestion of a foreign body. Esophageal foreign bodies are not always visible on X-rays and we must rely on other diagnostic methods like CT scan and endoscopy. This case ilustrates the accidental ingestion of the seal of a milk carton.

Host inflammatory response to polypropylene implants: insights from a quantitative immunohistochemical and birefringence analysis in a rat subcutaneous model

ABSTRACT Objectives To describe acute and sub acute aspects of histological and immunohistochemical response to PP implant in a rat subcutaneous model based on objective methods. Materials and Methods Thirty rats had a PP mesh subcutaneously implanted and the same dissection on the other side of abdomen but without mesh (sham). The animals were euthanized after 4 and 30 days. Six slides were prepared using the tissue removed: one stained with hematoxylin-eosin (inflammation assessment); one unstained (birefringence evaluation) and four slides for immunohistochemical processing: IL-1 and TNF-α (pro-inflammatory cytokines), MMP-2 (collagen metabolism) and CD-31 (angiogenesis). The area of inflammation, the birefringence index, the area of immunoreactivity and the number of vessels were objectively measured. Results A larger area of inflammatory reaction was observed in PP compared to sham on the 4th and on the 30th day (p=0.0002). After 4 days, PP presented higher TNF (p=0.0001) immunoreactivity than sham and no differences were observed in MMP-2 (p=0.06) and IL-1 (p=0.08). After 30 days, a reduction of IL-1 (p=0.010) and TNF (p=0.016) for PP and of IL-1 (p=0.010) for sham were observed. Moreover, area of MMP-2 immunoreactivity decreased over time for PP group (p=0.018). Birefringence index and vessel counting showed no differences between PP and sham (p=0.27 and p=0.58, respectively). Conclusions The implantation of monofilament and macroporous polypropylene in the subcutaneous of rats resulted in increased inflammatory activity and higher TNF production in the early post implant phase. After 30 days, PP has similar cytokines immunoreactivity, vessel density and extracellular matrix organization.

Inflammatory reaction and tensile strength of the abdominal wall after an implant of polypropylene mesh and polypropylene/poliglecaprone mesh for abdominal wall defect treatment in rats

PURPOSE: To compare the inflammatory reaction and the growing resistance of the abdominal wall with the use of poliglecaprone meshes and polypropylene meshes associated with poliglecaprone in the correction of abdominal defects. METHODS: Seventy-seven Wistar rats were divided into three groups: CG (non-operated animals: EG (polypropylene mesh) and UG (polypropylene and poliglecaprone mesh). A muscular and aponeurotic defect was formed and treated according to the group. Evaluations were made after 4, 7, 14, 28 and 56 days. The resistance and inflammatory pattern were studied. RESULTS: There was a gradual and significant gain in resistance, regularly in the EG and irregularly in the UG, which was lower on the 14th day (p=0.008). The inflammatory reaction was acute and more intense in the UG on the fourth day. At all other times, the inflammatory pattern was acute to chronic, similar in both groups, with minimum intensity on the 56th day. CONCLUSION: The greater resistance offered by the polypropylene mesh was regular and ascending, stabilizing on the 28th day, while that of the polypropylene/poliglecaprone was not even. In the end, the resistances were similar. The inflammatory response was greater in the UG on the fourth day and similar at all other times. .

Histopathological reaction over prosthesis surface covered with silicone and polyurethane foam implanted in rats / Reação histopatológica sobre a superfície de próteses cobertas por espuma de silicone e poliuretano implantadas em ratos

PURPOSES: To evaluate whether polyurethane foam leads more intense foreign-body reaction than silicone foam. To compare the vascularization of the capsules surrounding the foam implants. To investigate if the capsule of polyurethane foam implanted has greater amount of collagen than that of silicone foam. METHODS: Sixty-four young male Wistar rats were allocated into two groups: polyurethane foam and silicone foam. Subcutaneous discs were implanted into the dorsum of the animals in both groups. The capsules were assessed 28 days, two months, three months and six months postoperatively. Microscopic analysis with H&E stain was performed to evaluate the acute and chronic inflammatory process, foreign-body reaction and neovascularization. The analysis with picrosirius red was performed using the ImageProPlus software, to measure the number of vessels and collagen types I and III. RESULTS: There were no statistical differences between the two groups regarding the acute and chronic inflammatory processes. All rats from the polyurethane group, in all times, exhibited moderate or intense foreign-body reaction, with statistic significant difference (p=0.046) when compared with the silicone group, in which the reaction was either mild or nonexistent at two months. Vascular proliferation was significantly different between the groups at 28 days (p=0.0002), with the polyurethane group displaying greater neovascularization with H&E stain. Similar results were obtained with picrosirius red, which revealed in the polyurethane group a much greater number of vessels than in the silicone group (p=0.001). The collagen area was larger in the polyurethane group, significantly at 28 days (p=0.001) and at two months (p=0.030). CONCLUSIONS: Polyurethane foam elicited more intense foreign-body reaction when compared with silicone foam. The number of vessels was higher in the capsules of the polyurethane foam implants 28 days after the operation. The capsule of the polyurethane foam implants showed a greater amount of collagen than that of the silicone foam implants.

OBJETIVOS: Avaliar, em relação ao uso de próteses, se a espuma de poliuretano apresenta maior reação de corpo estranho no organismo ao ser comparada com a espuma de silicone. Se há diferenças na vascularização das cápsulas formada ao redor das duas espumas implantadas. Se as cápsulas dos implantes de espuma de poliuretano apresentam quantidade maior de fibras colágenas ao serem comparadas com as da espuma de silicone. MÉTODOS: Utilizou-se 64 ratos albinos da linhagem Wistar, distribuídos em dois grupos de 34, grupo espuma de poliuretano e grupo espuma de silicone e receberam implantes discóides subcutâneos em seu dorso. Foram analisadas as cápsulas peri-implante com 28 dias, dois, três e seis meses após a introdução. A análise microscópica com H&E considerou as variáveis: inflamação aguda, inflamação crônica, reação de corpo estranho e neoformação vascular. A análise da coloração com picrosirius-red usando ImageProPlus considerou o número de vasos e colágeno tipo I e tipo III. RESULTADOS: Em relação à inflamação aguda e crônica, não foram encontradas diferenças estatísticas nos dois grupos. Todos os animais do grupo poliuretano, em todos os momentos, apresentaram reação de corpo estranho moderada ou intensa e foi encontrada diferença estatística significativa (p=0,046) ao serem comparados com o grupo silicone, cuja reação era ausente ou discreta aos dois meses. A neoformação vascular apresentou diferenças significativas nos dois grupos, aos 28 dias (p=0,0002); o grupo poliuretano com H&E apresentava quantidade maior de vasos neoformados e o mesmo ocorrendo com o picrosirius, cujo número de vasos era maior que no grupo silicone (p=0,001). A área de colágeno em todos os momentos foi maior no grupo poliuretano, sendo significativa com 28 dias (p=0,001) e com dois meses (p=0,030). CONCLUSÕES: A espuma de poliuretano apresentou maior reação de corpo estranho no organismo do que a espuma de silicone. A quantidade de vasos foi maior na cápsula da espuma de poliuretano com 28 dias após o implante. Aos 28 dias as cápsulas dos implantes de espuma de poliuretano apresentaram quantidade significativamente maior de colágeno do que as de espuma de silicone.

Evaluation of peritoneal adhesions formation and tissue response to polypropylene - poli (2-hydroxyethyl methacrylate)-(polyHEMA) implant on rats' abdominal wall / Avaliação da formação de aderências peritoneais e da resposta tecidual ao implante de poli (2-hidroxietil dimetacrilato)-(poliHEMA) na parede abdominal de ratos

PURPOSE: To verify if the composit poli (2-hydroxyethyl methacrylate)-PolyHEMA/polypropylene mesh implanted in the female rat's abdominal wall could be suitable for the prevention of peritoneal adhesions, and for the evaluation of the tecidual response produced by this biomaterial. METHODS: Polypropylene meshes (Group PP, n=20) and polypropylene meshes coated with a layer of poli (2-hydroxyethyl methacrylate)-PolyHEMA (Group PH, n=20) were implanted on the abdominal wall of Wistar female rats. Ten animals from each group were submitted to euthanasia at 15 and 30 days of the postoperative period. RESULTS: The animals from the group PP presented visceral adhesions on the mesh surface, which was not observed in the ones from group PH. At the histopathological examination foreign body response was observed in both groups, whilst there was a greater intensity of inflammatory response in group PH on both moments. CONCLUSION: The poli (2-hydroxyethyl methacrylate) polyHEMA hydrogel associated to polypropylene mesh reduces visceral adhesion formation in rats, although it may be associated to greater inflammatory reaction.

OBJETIVO: Verificar se compósito poli 2-hidroxietil dimetacrilato (PoliHEMA) / tela de polipropileno implantado na parede abdominal de ratas seria adequado para prevenção de aderências peritoneais e avaliar a resposta tecidual desencadeada por este biomaterial. MÉTODOS: Foram implantadas telas de polipropileno - Grupo PP (n=20) e telas de polipropileno revestidas por uma camada de poli 2 (hidroxietil dimetacrilato)-PolyHEMA - Grupo PH (n=20) na parede abdominal de ratas da linhagem Wistar. Dez animais de cada grupo foram submetidos à eutanásia aos 15 e 30 dias de pós-operatório. RESULTADOS: Os animais do grupo PP apresentaram aderências viscerais na superfície da tela, o que não foi observado nos do grupo PH. Observou-se no exame histopatológico resposta tipo corpo estranho nos dois grupos sendo que no grupo PH houve maior intensidade de resposta inflamatória nos dois momentos. CONCLUSÃO: O hidrogel de poliHEMA quando associado à tela de polipropileno reduz a formação de aderências viscerais em ratos, embora possa estar associado à reação inflamatória mais intensa.

Effects of folk medicinal plant extract Ankaferd Blood Stopper® on early bone healing

OBJECTIVE: Several haemostatic agents are available for clinical use. Ankaferd Blood Stopper® (ABS), a mixture of five medicinal plant extracts, has been used historically as a haemostatic agent. The aim of this in vivo study was to investigate the effects of ABS on early bone healing using a rat tibia defect model. MATERIAL AND METHODS: Sixteen male Wistar rats were randomized into two groups of 8 animals each. After deep anesthesia with ketamine, bone defects (3 mm diameter and 2 mm deep) were created in the right and left tibiae of all animals and either treated with 1 cc of ABS (Group 1) or left untreated (Group 2; control). Surgical areas were closed primarily. The animals were sacrificed on the 7th postoperative day and bone samples were collected from the tibias. The samples were examined histopathologically for infection, necrosis, fibrosis, new bone formation and foreign body reaction. The histomorphometric results were analyzed statistically by the chi square test, with the level of significance set at p<0.05. RESULTS: Significant differences were found in both groups in terms of inflammation, necrosis and new bone formation (p=0.001, p=0.0001, p=0.001). No foreign body reaction was observed in the experimental group. ABS application decreased fibrosis in the experimental group, but there were no statistically significant differences from the control group. CONCLUSIONS: Histopathologically, it was observed that the application of ABS decreased the occurrence of inflammation and necrosis, while increasing new bone formation in early bone healing period. Further in vitro and in vivo studies are necessary for evaluating the benefits and possible adverse effects of the application of this herbal product on wound healing.

Aspiração de corpo estranho por menores de 15 anos: experiência de um centro de referência do Brasil / Foreign body aspiration in children and adolescents: experience of a Brazilian referral center

Objetivo: Descrever as características clínicas, radiológicas e endoscópicas da aspiração de corpo estranho por menores de 15 anos em um centro de referência em São Luís, MA. Métodos: Estudo descritivo realizado a partir de dados de prontuários dos pacientes atendidos no Hospital Universitário Materno Infantil devido à aspiração decorpo estranho entre 1995 e 2005. Avaliamos 72 casos confirmados de aspiração de corpo estranho em relação à procedência, variáveis biológicas, clínico-radiológicas e endoscópicas. Para verificar se as frequências observadas das variáveis em estudo foram estatisticamente significantes, utilizamos o teste do qui-quadrado. Resultados: A maioria do pacientes era procedente das cidades do interior (55,6%). As maiores frequências das diferentes variáveis estudadas foram as seguintes: faixa etária de 0-3 anos (81,9%); sexo masculino (63,9%); tempo de evolução > 24 h (66,7%); hipotransparência na radiografia de tórax (57,7%); localização do corpo estranho no pulmão direito (41,2%) ou na laringe (20.5%); natureza orgânica do corpo estranho (83,3%); complicação como processo inflamatório localizado (59,4%); edema de glote como complicação do exame endoscópico (47,6%); e sementes(46,6%), espinha de peixe (28,3%) e plásticos (25,5%) como tipos mais frequentes de corpos estranhos aspirados. Não houve óbitos. Conclusões: Cuidados preventivos devem priorizar crianças menores de três anos de idade, do sexo masculino, provenientes de cidades do interior. O acesso dessas crianças às substâncias com risco potencial para aspiração, incluindo os alimentos, deve ser evitado. Exames radiológicos simples e de fácil acesso à população são subutilizados, o que compromete a qualidade do primeiro atendimento.

Objective: To describe the clinical, radiological and endoscopic characteristics of foreign body aspiration among individuals under the age of 15 treated at a referral center in the city of São Luís, Brazil. Methods: This was a descriptive study using data from the medical charts of patients treated for foreign body aspiration at theHospital Universitário Materno Infantil between 1995 and 2005. We investigated 72 confirmed cases of foreign body aspiration, evaluating the place of residence, as well as biological, clinical, radiological and endoscopicvariables. We used the chi-square test to identify statistically significant differences in frequency among thevariables studied. Results: The majority of the patients were from outlying areas (55.6%). The following variables presented the highest frequencies: 0-3 year age bracket (81.9%); male gender (63.9%); evolution > 24 h (66.7%);hypotransparency on chest X-ray (57.7%); foreign body in the right lung (41.2%) or in the larynx (20.5%); organic nature of the foreign body (83.3%); complication in the form of localized inflammation (59.4%); glottal edema as an endoscopic complication (47.6%); and seeds (46.6%), fishbone (28.3%) or plastics (25.5%) as the type of foreign body. There were no deaths. Conclusions: Preventive care should be a priority for male children under the age of 3 living in outlying areas. Such children should not be given access to substances that can be aspirated, including certain foodstuffs. Simple and easily accessible radiological tests have been underused, which jeopardizes the quality of the initial treatment.

Experiencia con la técnica de Clotteau-Prémont en hernias de pared abdominal: reporte preliminar / Experience with Clotteau-Prémont's technique in abdominal wall hernias: preliminary report

Introducción: las hernias posincisionales representan por lo menos un tercio de las hernias de pared. Existen diferentes técnicas de reparación que incluyen el uso de material protésico, lo que ha contribuido a disminuir la recidiva. Sin embargo, ante el rechazo o infección se requieren otras técnicas con tejido autólogo, dado que el uso de material protésico en un ambiente contaminado está contraindicado, pues el riesgo de infección y recurrencia es inaceptablemente alto. Objetivo: comparar dos técnicas de tratamiento para las hernias de pared abdominal en términos de complicaciones posoperatorias y recidiva, para determinar las alternativas en el cierre de pared abdominal en pacientes con hernias ventrales. Material y métodos: se realizó estudio observacional, longitudinal, retrospectivo, de casos y controles pareados, no aleatorizado, en pacientes con hernia de pared, entre enero de 2000 y enero de 2004. Se estudiaron 30 pacientes divididos en dos grupos de 15 pacientes cada uno, pareados por sexo, edad y tipo de hernia: grupo A, pacientes tratados con malla; grupo B, pacientes tratados con técnica Clotteau-Prémont. El seguimiento posoperatorio fue de por lo menos cinco meses. Se evaluó y comparó el índice de complicaciones y recidivas. Resultados: no hubo diferencia entre ambos grupos en complicaciones o recidiva (p < 0.05). El tiempo de seguimiento promedio fue de 18.9 ± 8 meses para el grupo A y de 15 ± 7.9 meses para el grupo B. Conclusiones: la técnica de Clotteau-Prémont es un procedimiento factible y seguro en pacientes seleccionados.

BACKGROUND: Incisional hernias account for at least a third of abdominal wall hernias. There are different techniques of repair that include the use of prosthetic materials, which has lowered the hernia recurrence rate. Nonetheless, its use in case of rejection or infection requires other techniques with local tissue. The use of prosthetic material in a contaminated environment is contraindicated because the risk of infection and recurrence rate is unacceptably high. METHODS: In order to compare two repair techniques for abdominal wall hernias in terms of complications and recurrence to be used as an alternative for hernia repair in patients with abdominal wall hernias, we conducted, between January 2000 and January 2004, an observational, longitudinal, retrospective, non-randomized matched control case study in patients with abdominal wall hernia. A total of 30 patients were studied and were divided into two groups of 15 patients each. Subjects were matched for sex, age and hernia type (group A, mesh treated and group B, Clotteau-Prémont treated) who had at least a 5-month postoperative follow-up. Complication and recurrence rate was assessed and compared. RESULTS: There were no differences between the two groups in complications or recurrence (p <0.05). The average follow-up time was 18.9 +/- 8 months for group A and 15 +/- 7.9 months for group B. CONCLUSIONS: Clotteau-Prémont's technique is a safe and feasible alternative procedure with indications in selected patients.
