ABSTRACT

ABSTRACT Objective To verify the efficacy of high voltage pulsed current in collagen realignment and synthesis and in angiogenesis after the partial rupturing of the Achilles tendon in rats. Method Forty male Wistar rats were randomized into four groups of 10 animals each: sham, cathodic stimulation, anodic stimulation, and alternating stimulation. Their Achilles tendons were submitted to direct trauma by a free-falling metal bar. Then, the treatment was administered for six consecutive days after the injury. In the simulation group, the electrodes were positioned on the animal, but the device remained off for 30 minutes. The other groups used a frequency of 120 pps, sensory threshold, and the corresponding polarity. On the seventh day, the tendons were removed and sent for histological slide preparation for birefringence and Picrosirius Red analysis and for blood vessel quantification. Results No significant difference was observed among the groups regarding collagen realignment (types I or III collagen) or quantity of blood vessels. Conclusion High voltage pulsed current for six consecutive days was not effective in collagen realignment, synthesis, or angiogenesis after the partial rupturing of the Achilles tendon in rats.

ABSTRACT

BACKGROUND: Tendon injury is one of the most frequent injuries in sports activities. TENS is a physical agent used in the treatment of pain but its influence on the tendon's healing process is unclear. OBJECTIVE: To evaluate the influence of TENS on the healing of partial rupture of the Achilles tendon in rats. METHOD: Sixty Wistar rats were submitted to a partial rupture of the Achilles tendon by direct trauma and randomized into six groups (TENS or Sham stimulation) and the time of evaluation (7, 14, and 21 days post-injury). Burst TENS was applied for 30 minutes, 6 days, 100 Hz frequency, 2 Hz burst frequency, 200 µs pulse duration, and 300 ms pulse train duration. Microscopic analyses were performed to quantify the blood vessels and mast cells, birefringence to quantify collagen fiber alignment, and immunohistochemistry to quantify types I and III collagen fibers. RESULTS: A significant interaction was observed for collagen type I (p=0.020) where the TENS group presented lower percentage in 14 days after the lesion (p=0.33). The main group effect showed that the TENS group presented worse collagen fiber alignment (p=0.001) and lower percentage of collagen III (p=0.001) and the main time effect (p=0.001) showed decreased percentage of collagen III at 7 days (p=0.001) and 14 days (p=0.001) after lesion when compared to 21 days. CONCLUSIONS: Burst TENS inhibited collagen I and III production and impaired its alignment during healing of partial rupture of the Achilles tendon in rats.

ABSTRACT

Objective: To translate, culturally adapt, and validate a Brazilian Portuguese version of the Yale-Brown Obsessive Compulsive Scale modified for Body Dysmorphic Disorder (BDD-YBOCS). Methods: Ninety-three patients of both sexes seeking rhinoplasty were consecutively selected at the Plastic Surgery Outpatient Clinic of the Universidade Federal de São Paulo, Brazil, between May 2012 and March 2013. The BDD-YBOCS was translated into Brazilian Portuguese. Thirty patients participated in the cultural adaptation of the scale. The final version was tested for reliability in 20 patients, and for construct validity in 43 patients (correlation of the BDD-YBOCS with the Body Dysmorphic Disorder Examination [BDDE]). Results: Total Cronbach’s alpha was 0.918. The BDD-YBOCS had excellent inter-rater (intra-class correlation coefficient [ICC] = 0.934; p < 0.001) and intra-rater reliability (ICC = 0.999; p < 0.001). Significant differences in BDD-YBOCS scores were found between patients with and without BDD symptoms (p < 0.001), and among patients with different levels of BDD severity (p < 0.001). A strong correlation (r = 0.781; p < 0.001) was observed between the BDDE and the BDD-YBOCS. The area under the receiver operating characteristic curve was 0.851, suggesting a very good accuracy for discriminating between presence and absence of BDD symptoms. Conclusion: The Brazilian Portuguese version of the BDD-YBOCS is a reliable instrument, showing face, content and construct validity.

ABSTRACT

PURPOSE: This study is a systematic literature review and meta-analysis concerning the use of a testosterone synthetic analog, oxandrolone, and its use in severe adult burns. METHODS: Randomized prospective clinical studies, in English, Portuguese or Spanish, were sought on the following databases: MEDLINE, COCHRANE, EMBASE and LILACS. There was no restriction in relation to the publication date. RESULTS: This search produced 24 studies on MEDLINE and twelve articles were presented on the COCHRANE database .Sixteen were excluded due to the title not being related to this search or by including children. Of the eigth residual studies, after adaptation to the inclusion criteria, only four were selected. After analyzing the results, two were discarded since they did not present adequate patient characterization and the facts on these articles were analyzed differently from the others, hindering the meta-analysis. CONCLUSION: The analysis of the available data demonstrated significant benefits (p<0.05) considering lesser loss of corporal mass, lesser nitrogen loss, and shorter donor area healing time, when Oxandrolone was used, comparatively with the control group (placebo or not). .

ABSTRACT

BACKGROUND: Depression is prevalent among women and associated with reduced quality of life, and therefore it is important to determine its incidence in adult women, especially in those with breast cancer. OBJECTIVE: To determine the occurrence of depression in women who underwent conservative surgery for breast cancer with or without breast reconstruction. METHODS: Seventy-five women aged between 18 and 65 years were enrolled. Patients had undergone conservative surgery for breast cancer with immediate breast reconstruction (n = 25) or without breast reconstruction (n = 25) at least one year before the study. The control group consisted of 25 women without cancer, but of similar age and educational level distribution as the other two groups. The Beck Depression Inventory was used to measure depression. The collected data were assessed using analysis of variance and the χ2 test. RESULTS: There were no significant differences between groups in age (p = 0.72) or educational level (p = 0.20). A smaller number of patients had undergone the menopause (p = 0.02) in the control group than in other groups. There were no significant differences in occurrence of depression between groups (χ2=9.97; p = 0.126). CONCLUSÍON: Conservative surgery for breast cancer did not affect the occurrence of depression in women, regardless of whether breast reconstruction was performed.

ABSTRACT

There comes a time when the understanding of the cutaneous healing process becomes essential due to the need for a precocious tissue repair to reduce the physical, social, and psychological morbidity. Advances in the knowledge on the control of interaction among cells, matrix and growth factors will provide more information on the Regenerative Medicine, an emerging area of research in medical bioengineering. However, considering the dynamism and complexity of the cutaneous healing response, it is fundamental to understand the control mechanism exerted by the interaction and synergism of both systems, cutaneous nervous and central nervous, via hypothalamus hypophysis-adrenal axis, a relevant subject, but hardly ever explored. The present study reviews the neuro-immune-endocrine physiology of the skin responsible for its multiple functions and the extreme disturbances of the healing process, like the excess and deficiency of the extracellular matrix deposition.


Aproxima-se uma época na qual é fundamental a compreensão do processo cicatricial cutâneo frente à necessidade da restauração tecidual precoce, visando a diminuição das morbidades física, social e psicológica. O avanço no conhecimento acerca do controle das interações entre as células, a matriz e os fatores de crescimento dará maiores informações à Medicina Regenerativa, área de pesquisa emergente da bioengenharia médica. Entretanto, diante do dinamismo e complexidade da resposta cicatricial cutânea torna-se indispensável o entendimento do mecanismo de controle exercido pela interação e sinergismo do sistema nervoso cutâneo e o sistema nervoso central, via eixo hipotálamo-hipófise-adrenal, tema relevante, porém, pouco abordado. O presente estudo revisa a fisiologia neuro-imuno-endócrina da pele, responsável por suas múltiplas funções, e os distúrbios extremos do processocicatricial, como o excesso e deficiência de deposição da matriz extracelular.

ABSTRACT

Objetivos: Avaliar o impacto do tratamento cirúrgico da ssimetria mamária primária na qualidade de vida. Métodos: Foi aplicado, pré-operatório e aos 3 e 6 meses após mastoplastia , o questionário genérico de qualidade de vida, "Medical Outcomes Study 36-item Short Form Health Survey" (SF-36), o qual avalia qualidade de vida em oito domínios (capacidade funcional, aspectos físicos, dor, estado geral de saúde, vitalidade, aspectos sociais, aspecto emocional e saúde mental). Resultados: Houve alterações positivas estatisticamente significativas em quatro dos oito aspectos avaliados pelo SF-36. As diferenças em relação ao pré-operatório foram: nos aspectos emocionais, no 3º mês pós-operatório, e no 6º mês pós-operatório, na dor, vitalidade e saúde mental. Conclusões: O tratamento cirúrgico da assimetria mamária promoveu um impacto positivo na qualidade de vida das pacientes.

ABSTRACT

O tratamento do câncer de mama provoca seqüelas físicas e psicológicas permanentes, as quais estão relacionadas ao procedimento cirúrgico. Mulheres submetidas à mastectomia radical modificada podem ter valores emocionais e afetivos alterados. Foi avaliada, por meio de um instrumento validado no Brasil, a auto-estima de pacientes submetidas à mastectomia por câncer de mama. Foram avaliadas 40 pacientes submetidas à mastectomia havia mais de 1 ano. Elas passaram por entrevistas com questionários específicos para auto-estima e para dados sociodemográficos. Outro grupo de 40 mulheres não portadoras de neoplasia mamária e um terceiro grupo com 15 mulheres submetidas a tratamento cirúrgico conservador foram avaliados como controle. Obtiveram-se os valores de p mediante os testes de Kruskal-Wallis, Mann-Whitney e qui-quadrado. Na Escala de Auto-estima de Rosenberg, 27% de todas as pacientes estudadas apresentaram escores superiores a 10, e a média total do grupo mastectomizado foi de 7,9 no grupo de cirurgia conservadora a média foi de 9,8 e no grupo-controle, 4. Esses resultados confirmam a baixa auto-estima das pacientes quando comparadas às do grupo sem neoplasia (p = 0,0001). Quando a mastectomia e a cirurgia conservadora foram correlacionadas por meio do teste de comparações múltiplas, não houve significância estatística. A conclusão foi que a perda da mama, ou parte dela, promove um impacto negativo na auto-estima das pacientes.


The treatment of breast cancer causes permanent physical and psychological sequelae, which are related to the surgical procedure. Women who underwent modified radical mastectomy may have altered affective and emotional values. Was evaluated using a validated instrument in Brazil, self-esteem of patients undergoing mastectomy for breast cancer. We evaluated 40 patients who underwent mastectomy had more than 1 year. They went through interviews with specific questionnaires for self-esteem and demographic data. Another group of 40 women not suffering from breast cancer and a third group with 15 women undergoing conservative surgery were evaluated as controls. We obtained p values by the Kruskal-Wallis, Mann-Whitney and chi-square. Scale Rosenberg Self-esteem, 27% of all patients studied had scores above 10, and the average total mastectomy group was 7.9 in the group of conservative surgery the average was 9.8 and in the control group 4. These results confirm the low self-esteem of patients when compared to those of patients without cancer (p = 0.0001). When mastectomy and conservative surgery were correlated through the test of multiple comparisons, no statistical significance. The conclusion was that the loss of the breast, or part of it promotes a negative impact on self-esteem of patients.

ABSTRACT

OBJETIVO: As fraturas mandibulares podem levar a grandes prejuízos estéticos, funcionais e financeiros e suas características epidemiológicas têm sofrido alterações em diversas localidades. Para detectar estas mudanças, foi realizado este estudo, cujo objetivo foi comparar os dados de pacientes com fraturas mandibulares atendidos no Hospital São Paulo (UNIFESP-EPM) no período de junho de 1999 a março de 2002 aos de pacientes atendidos de janeiro de 1991 a março de 1996. MÉTODOS: Foram comparados o sexo e faixa etária mais acometidos, locais mais fraturados do osso, lesões associadas, tratamento e complicações de 98 pacientes com fratura de mandíbula, atendidos pelo Setor de Cirurgia Craniofacial da Disciplina de Cirurgia Plástica UNIFESP-EPM no período de junho de 1999 a março de 2002 aos mesmos dados de 166 pacientes atendidos de janeiro de 1991 a março de 1996. RESULTADOS: O sexo e a faixa etária mais acometidos ainda são os mesmos. Os acidentes de transporte, como principais causas de fraturas mandibulares, foram substituídos pelas agressões. Houve diminuição de lesões associadas e de fraturas múltiplas na mandíbula, provavelmente associadas à mudança etiológica. O local mais acometido continua sendo o corpo. O tratamento mais utilizado nos dois grupos foi a fixação com miniplaca, e o número de complicações diminuiu, provavelmente devido à melhora do padrão de atendimento. CONCLUSAO: Houve mudanças nas características epidemiológicas das fraturas mandibulares na população de São Paulo e o conhecimento das mesmas possibilita a instituição de medidas preventivas e de tratamento adequadas.

ABSTRACT

Objetivo: apresentar um caso de melanoma cutâneo na infância, submetido à biópsia de linfonodo sentinela.Descrição: criança de 12 anos de idade, portadora da sindrome do nevo displásico, desenvolveu melanoma em dorso. A biópsia excisional revelou melanoma (Breslow = 1 ,5 mm), sendo submetida a tratamento cirúrgico da lesão, com ampliação de margem de 2cm e biópsia de linfonodo sentinela. O exame anatomopatológico não mostrou doença residual. O exame do linfonodo sentinela não mostrou metástases ao exame histopatológico por hematoxilinaeosina, nem à imunohistoquímica (S100 e HMB45). No entanto, a pesquisa de RNA mensageiro da tirosinase por RT-PCR se mostrou positiva. A paciente não mostrou sinais de metástase ou recidiva local nestes doze meses iniciais de seguimento. Comentáríos: o melanoma é raro em crianças, corresponde a menos de 1por cento dos tumores da infância. Inúmeros trabalhos mostram o aumento da incidência mundial do melanoma. Em cerca de 70por cento, se originam de nevos melanocíticos pré-existentes, e nos 30por cento restantes, eles surgem de novo. Dada a agressividade do melanoma, a sobrevida depende do diagnóstico precoce. A biópsia do infonodo sentinela tem contribuído na decisão de se realizar ou não a linfadenectomia completa, e alguns autores já estão utilizando a mesma em crianças

ABSTRACT

O presente estudo teve como objetivo veriricar o efeito do dimetilsulfóxido (DMSO) na necrose da porção distal de retalhos cutâneos randômicos, adminstrado via enteral, em ratos. O material constitui-se de 28 ratos, linhagem Wistar-EPM. O retalho cutâneo randômico foi realizado com dimensões de 10x4 cm e uma barreira plástica foi interposta entre o retalho e o leito doador. O Grupo 1 (Controle) recebeu água destilada diariamente por sete dias e o Grupo 2 recebeu 2ml/kg/dia de DMSO, por gavagem, por sete dias. Nos dois grupos foram calculadas as porcentagens de área de necrose (média de 65.70 por cento no Grupo 1 e de 31.37 por cento no Grupo 2), em amostras de pele normal (média de 2037 ng/ml no Grupo 1 e de 1006 ng/ml no Grupo 2) e da transição de pele viável-necrótica (média de 1235 ng/ml no Grupo 1 e de 516 ng/ml no grupo 2). A análise estatística mostrou que o DMSO foi eficiente na redução da área de necrose e dos valores de MDA comparando-se ao Grupo controle.
