Histological modification in TRAM flap in rats treated with pentoxifylline

PURPOSE: To investigate the blood vessels' concentration in TRAM flap's rat model, in the presence of pentoxifylline.METHODS:32 male, Wistar-EPM rats were divided into two groups. Control group (C): 0.5 ml of saline, intraperitoneally, once a day, for seven days before flap elevation; PTX group (P): pentoxifylline (20mg/kg/day), intraperitoneally, for seven days before flap elevation. After that, they were submitted to a caudal unipedicle TRAM flap. On the fifth postoperative day, percentages of flap necrosis were determined via the paper template method and Tram flap's zone IV skin biopsies were taken for histological analysis.RESULTS:the mean percentage of flap necrosis in group C was 58.7 % and in group P, 31.1 (Wilcoxon test; p = 0.003). Mean capillary vessels number in zone IV's skin in C group was 33.4 and in P group was 71.9 (p=0.008).CONCLUSIONS: Pentoxifylline was effective reducing the necrosis in the caudal unipedicle TRAM flap in the rat as well as increasing the number of capillaries in an ischemic zone (zone IV).UNIFESP Surgery DepartmentUNIFESP Pathology DepartmentUNIFESPUNIFESP, Surgery DepartmentUNIFESP, Pathology DepartmentUNIFESPSciEL

Retalho em hélice para reconstrução de sequelas em membros inferiores

Introdução: O retalho em hélice, ou propeller flap, é um tipo de retalho local baseado em vasos perfurantes. Apresenta diversas vantagens, como a reconstrução de tecidos semelhantes ao original, menor morbidade da área doadora, manutenção dos principais vasos da região e a possibilidade de amplo arco de rotação (até 180º). Entretanto, está sujeito a complicações, sendo a mais preocupante a necrose parcial ou total do retalho. Métodos: Estudo retrospectivo de uma série de três casos de sequelas de trauma em membros inferiores tratados com retalho em hélice. Resultados: Retalhos em hélice reduzem o tempo cirúrgico, dias de internação e custos. Todavia, não são isentos de complicações, encontra-se a ocorrência de necrose parcial de 10,5 a 11% e total de 1 a 5%. Outras complicações descritas são epidermólise (3,5%) e congestão venosa transitória (3%). Nos casos descritos, evoluíram sem complicações. Classicamente, os defeitos de membro inferior, principalmente no terço distal, têm indicação de reconstrução com retalhos microcirúrgicos. Conclusão: Os retalhos propeller podem ser uma alternativa nestes casos, principalmente em defeitos pequenos e moderados. Ainda não existem trabalhos comparando diretamente estas duas técnicas, mas algumas informações importantes já estão disponíveis, como a semelhança entre os percentuais de necrose total entre as técnicas

Propeller flap for reconstruction of sequelae in lower limbs

Introduction: The propeller flap is a type of local flap based on perforating vessels. It has several advantages, such as the reconstruction of tissues similar to the original, less morbidity of the donor area, maintenance of the main vessels of the region and the possibility of a wide rotation arc (up to 180º). However, it is subject to complications, the most worrisome being partial or total necrosis of the flap. Methods: A retrospective study of a series of three cases of lower limb trauma sequelae treated with helix flaps. Results: Helical flaps reduce surgical time, hospitalization days, and costs. However, they are not free of complications, with partial necrosis occurring in 10.5 to 11% and total necrosis in 1 to 5%. Other complications described are epidermolysis (3.5%) and transient venous congestion (3%). In the cases described, they evolved without complications. Classically, lower limb defects, especially in the distal third, are indicated for reconstruction with microsurgical flaps. Conclusion: Propeller flaps may be an alternative in these cases, especially in small and moderate defects. There are still no studies directly comparing these two techniques, but some valuable information is already available, such as the similarity between the percentages of total necrosis between the techniques

Cephalic vein transposition for head and neck microsurgical reconstruction: anatomical study in cadavers

Introduction: Cephalic vein transposition is an interesting alternative as a donor vein in head and neck cancer reconstruction in patients with a cervical radiotherapy history. This work aims to evaluate the cephalic vein anatomical characteristics in cadavers. Methods: Six cephalic veins from three cadavers were dissected. The veins were sectioned in the medial part of the arm and transposed to the neck over the clavicles. Results: The veins had an average length of 18.75 ± 1.84 cm and several tributaries with a variation of 7-9. The diameter coincided in both veins of each corpse. The anatomical parameter used to identify them (deltopectoral groove) proved reliable, allowing predictable dissection. Conclusion: The cephalic vein has constant characteristics and is easy to locate, being an option relevant to the reconstructive plastic surgeon's therapeutic arsenal

Fat grafting for the treatment of radiodermatitis after treatment of head and neck cancer

Introdução: Embora o tratamento do câncer de cabeça e pescoço tenha evoluído nos últimos anos, ainda é um desafio preservar e restaurar a simetria facial após o mesmo, comprometendo significativamente a qualidade de vida dos pacientes. Em cirurgia reconstrutiva, o enxerto de gordura autóloga vem sendo usado para tratar defeitos de volume e de contorno. O objetivo é revisar os efeitos do enxerto de gordura em pacientes com radiodermite, devido ao tratamento radioterápico de câncer de cabeça e pescoço. Métodos: Revisão de literatura nas bases PubMed e SciELO, buscando estudos publicados nos últimos 20 anos nas línguas portuguesa, inglesa ou espanhola. Foram utilizados os descritores "adipose tissue", "transplantation", "neoplasms", "head and neck neoplasms" e "radiotherapy"; e os termos não descritores "fat grafting", "fat transplantation" e "fat graft". Resultados: De 212 artigos encontrados, apenas 7 estavam em conformidade aos critérios de elegibilidade. Conclusão: A revisão sugere que a lipoenxertia em reconstrução oncológica de cabeça e pescoço é um tratamento seguro e permite otimizar os resultados estéticos e funcionais. Faltam estudos prospectivos para melhor definição de técnicas e de resultados

Tuberculose em ambiente hospitalar: perfil clínico em hospital terciário do ceará e grau de conhecimento dos profissionais de saúde acerca das medidas de controle -doi:10.5020/18061230.2010.p260

(TB) and to assess the knowledge of health personnel on fundamental concepts about TB and control measures for pulmonary tuberculosis in a hospital environment. Methods: The study was conducted in a tertiary hospital in Fortaleza-CE and involved patients admitted with TB and health professionals responsible for assistance. A first phase was characterized by a retrospective study of medical records of patients admitted with suspected TB. In a second stage, a cross-sectional study with application of a structured questionnaire assessed the knowledge of health personnel on TB control measures in a hospital environment. Results: Sixty-seven patients admitted with suspected TB had their medical records assessed. Among the confirmed cases, the most frequent clinical form was pulmonary (81.3%). Out of 55 patients admitted with suspected pulmonary tuberculosis, only 29 (52.7%) were admitted in a respiratory isolation bed. Twenty-six patients with suspected pulmonary tuberculosis on admission stayed a total of 148 days out of a respiratory isolation bed (average 4.1 days / patient). The knowledge of 159 health professionals about TB was assessed. Regarding the transmission of TB, 107 (67.2%) were unaware of airborne transmission and 109 (68.5%) ignored the clinical forms that require respiratory isolation. Conclusions: Pulmonary tuberculosis is the most frequent clinical form among inpatients in a tertiary hospital in Fortaleza- CE. Considerable fraction of health personnel doesn’t know key concepts related to tuberculosis and essential for the proper and safe care.Objetivos: Descrever características epidemiológicas e clínicas de pacientes internados com tuberculose (TB), além de avaliar o grau de conhecimento de profissionais de saúde acerca de conceitos fundamentais sobre TB e medidas de controle parapacientes com tuberculose pulmonar em ambiente hospitalar.
