RESUMO O objetivo desse trabalho é identificar o comportamento de alguns traços de concreto no qual há a substituição parcial da areia natural pela cinza de aterro sanitário. Foram propostos quatro traços, o primeiro com 100% areia natural, que será usado como traço de referência, o segundo com 5% de cinza de aterro sanitário, em relação a massa da areia natural, o terceiro com 10% de cinza, e, o quarto com 15% de cinza. Os traços dos concretos foram compostos de cimento, areia/cinza, brita e água, e, estes foram ensaiados quanto a sua resistência à compressão. Os resultados mostraram que os traços compostos com cinza apresentaram bom desempenho no que se refere a resistência à compressão. A relevância desse estudo se deve ao fato de que, os aterros sanitários, quando utilizado o processo de queima do lixo, produzem cinzas, ocasionando um impacto na natureza que gera um importante passivo ambiental. Portanto a utilização desse tipo de resíduo, possibilita a redução desse impacto ambiental.

ABSTRACT The objective of this work is to identify the behavior of some traces of concrete in which there is the partial replacement of the natural sand by the landfill ash. Four traces were proposed, the first one with 100% natural sand, which will be used as reference traces, the second with 5% ash from the landfill, in relation to the natural sand mass, the third with 10% ash, the room with 15% ash. The traces of the concretes were composed of cement, sand / ash, gravel and water, and these were tested for their compressive strength. The results showed that the composite traces with ash showed good performance with respect to the compressive strength. The relevance of this study is due to the fact that landfills, when used the process of burning the garbage, produce ashes, causing an impact on nature that generates an important environmental liability. Therefore, the use of this type of waste makes it possible to reduce this environmental impact.

Background: evidences have shown a strongly association between metabolic syndrome (MS), cardiovascular diseases and chronic low-grade inflammation, being this last, related with the occurrence of sarcopenia and atherosclerosis. Despite several benefits, the effects of resistance training (RT) on inflammatory profile are controversial. Thereby, this study aims to investigate the effects of a RT on the inflammatory profile of men with MS risk factors. Methods: fifteen sedentary men (57.53 ± 7.07 years old) with 2 or more MS components underwent a RT for 14 weeks (3 times per week), with intensity ranging between 40 and 70% of one repetition maximum. The dual-energy X-ray absorptiometry was used to body composition assessment and serum was collected to evaluate biochemical and inflammatory parameters before and after the RT. Results: despite the absence of changes in body weight, total muscular content and biochemical parameters, the individuals demonstrated a reduction on body fat content (p < 0.05). Furthermore, the RT resulted in lower circulating levels of tumor necrosis factor alpha and interleukin- 6 (p < 0.05), in higher levels of intelerukin-10 (p < 0.05) and in the stabilization of interleukin-1 beta and interferon-gamma concentrations. It was concluded that a moderate RT benefits inflammatory profile, contributing to a lower risk of cardiovascular diseases.

Introducción: la evidencia muestra la relación entre síndrome metabólico (SM), enfermedades cardiovasculares e inflamación crónica de bajo grado, que está relacionada con la aparición de sarcopenia y aterosclerosis. A pesar de muchos beneficios, los efectos del entrenamiento de resistencia (ER) sobre la inflamación son controvertidos. Este estudio tiene como objetivo investigar los efectos de 14 semanas de ER en el perfil inflamatorio de hombres con factores de riesgo para SM. Métodos: quince varones sedentarios (57,53 ± 7,07 años) con 2 o más componentes del SM fueron sometidos a un ER moderado durante 14 semanas (tres veces a la semana), con una intensidad que oscila entre 40 y 70% de una repetición máxima. La absorciometría dual de rayos X se utilizó para la evaluación de la composición corporal y el suero se recogió para evaluar los parámetros bioquímicos e inflamatorios antes y después de la ER. Resultados: a pesar del mantenimiento de la masa corporal, la masa muscular total y los parámetros bioquímicos, hubo una reducción en la grasa corporal (p < 0,05). Además, el ER disminuyó los niveles de factor de necrosis tumoral alfa e interleucina-6 circulante (p < 0,05), aumentó la concentración de interleucina-10 (p < 0,05) y mantuvo la interleucina-1 y el interferón-gamma. Se concluyó que 14 semanas de ER moderado provocan beneficios sobre el perfil inflamatorio, contribuyendo a la reducción del riesgo cardiovascular.

Introduction  Septum deviation in children may alter the early physiologic process of breathing, causing obligatory oral breathing and consequently changing craniofacial development and even intellect. Because of these consequences, septoplasty should be performed as early as possible. Materials and Methods  The retrospective study reviewed the results of septoplasty in 40 children under 12 years old who had follow-up after surgery for a maximum period of 7 years. The research was submitted to the ethics committee and approved with protocol number 10331912.0.0000.0058. Results  Forty patients underwent septoplasty, 39 (97.5%) had cauterization of inferior turbinate and associated procedure, 20 (50%) had adenotonsillectomy, and 17 (42.5%) had adenoidectomy. Conclusion  Nasal septum deviation should be corrected early to provide the harmonious growth of the face and to enable normal development of the child, without the occurrence of nasal deformity.

OBJETIVO:Apresentar nossa experiência em dacriocistorrinostomia endoscópica, discutindo os resultados com os encontrados na literatura. MÉTODOS: O material desse estudo consistiu de 16 dacricistorrinostomias realizadas em 12 pacientes acompanhados no período de 2009 a 2011. Analisamos sexo, idade no momento da cirurgia, etiologia da dacriocistite, quadro clínico, número de cirurgias necessárias para a correção, seguimento pós-operatório. RESULTADOS: Houve predomínio do sexo feminino em relação ao masculino (5:1) com idades entre 8 e 71 anos, com média de 35,2 anos. Com relação à etiologia, oito foram classificados como idiopáticos; três, pós-traumáticos e um iatrogênico. Os pacientes foram acompanhados em média durante o período de seis meses, com melhora dos sintomas. Apenas dois pacientes evoluíram com permanência de epífora, sendo um deles reoperado com êxito por via externa. CONCLUSÃO:A cirurgia endoscópica endonasal deve ser considerada nos pacientes com obstrução das vias lacrimais, devido ao seu alto índice de sucesso, além de ser um procedimento seguro, com menor morbidade e proporcionar melhor resultado estético.

OBJECTIVE:To present our experience in endoscopic dacryocystorhinostomy, discussing the results with those found in the literature.

We analyzed gender, age at surgery, etiology of dacryocystitis, clinical features, number of surgeries required to repair, follow-up. RESULTS: There was a predominance of females compared to males (5:1) aged between 8 and 71 years, mean35.2 years. With regard to etiology, eight were classified as idiopathic, three, posttraumatic, and one, iatrogenic. Patients were followed on average over the period of six months, with improvement of symptoms. Only two patients had persistence of epiphora, one being reoperated successfully by external approach. CONCLUSION: Endoscopic endonasal surgery should be considered in patients with lacrimal obstruction, due to its high success rate, besides being safe procedure with less morbidity and give better cosmetic results.

INTRODUCTION: Juvenile nasopharyngeal angiofibroma is a rare, highly vascular, and histologically benign tumor, generally observed in male adolescents. It shows very aggressive behavior due to local invasiveness and is associated with various symptoms. Juvenile nasopharyngeal angiofibroma originates in the sphenopalatine forame, causing epistaxes and nasal obstruction. OBJECTIVE: To retrospectively describe our experience in the diagnosis and treatment of patients with juvenile nasopharyngeal angiofibroma. SCIENTIFIC DRAWING: Retrospective, descriptive study conducted after approval from the Ethics Committee of the Federal University of Sergipe (protocol 0114.0.107.000 -11). METHODS: We analyzed findings in 20 patients who underwent surgery between 2004 and 2011. Factors analyzed include patient age and gender, symptoms, stages, treatment, length of surgery, intraoperatory bleeding, postoperative need for nasal tampons, hospitalization time, complications, and tumor recurrence. RESULTS: Patients were aged 10-29 years. All patients were treated surgically, including 17 who underwent endoscopic surgery. The mean operation time was 120 min, and the mean bleeding volume was 300 mL. Seventeen patients required clamping of the external carotids and tumor embolization. CONCLUSION: Endoscopic surgery alone or with other conventional techniques was safe for the treatment of angiofibromas of different stages.

INTRODUCTION: Cochlear Implants are important for individuals with severe to profound bilateral sensorineural hearing loss. OBJECTIVE: Evaluate the experience of cochlear implant center of Otorhinolaryngology through the analysis of records of 9 patients who underwent cochlear implant surgery. METHODS: This is a retrospective study performed with the patients records. Number 0191.0.107.000-11 ethics committee approval. We evaluated gender, etiology, age at surgery, duration of deafness, classification of deafness, unilateral or bilateral surgery, intraoperative and postoperative neural response and impedance of the electrodes in intraoperative and preoperative tests and found those that counter-indicated surgery. RESULTS: There were 6 pediatric and 3 adult patients. Four male and 5 female. Etiologies: maternal rubella, cytomegalovirus, ototoxicity, meningitis, and sudden deafness. The age at surgery and duration of deafness ranged from 2 - 46 years and 2 - 18 years, respectively. Seven patients were pre-lingual. All had profound bilateral PA. There were 7 bilateral implants. Intraoperative complications: hemorrhage. Complications after surgery: vertigo and internal device failure. In 7 patients the electrodes were implanted through. Telemetry showed satisfactory neural response and impedance. CT and MRI was performed in all patients. We found enlargement of the vestibular aqueduct in a patient and incudomalleolar malformation. CONCLUSION: The cochlear implant as a form of auditory rehabilitation is well established and spreading to different centers specialized in otoaudiology. Thus, the need for structured services and trained professionals in this type of procedure is clear.

FUNDAMENTOS: A produção científica da dermatologia brasileira, qualitativa e quantitativamente, é pouco conhecida. OBJETIVO: Avaliar a produção científica dos dermatologistas vinculados a instituições brasileiras. MÉTODOS: Foram analisados os cinco jornais de maior fator de impacto em dermatologia. Compilados os trabalhos vinculados a instituições brasileiras de 1986 a 2010 e analisados: posição dos pesquisadores Brasileiros na lista de autores, objeto temático, delineamento, doença estudada, área de interesse da investigação e ano de publicação. RESULTADOS: Foram contabilizados setenta e quatro trabalhos realizados por dermatologistas de instituições brasileiras. Agrupando os trabalhos de cinco em cinco anos, um aumento importante foi observado na produção brasileira de 2006 em diante. Os dermatologistas foram classificados como investigadores secundários na maioria dos casos (53,66%). Segundo o objeto temático estudado, a maioria dos artigos era de enfoque laboratorial (45,95%). Em relação ao delineamento, constatou-se que os trabalhos na maioria eram transversais ou ensaios clínicos não controlados (ambos com 17,57%). Os trabalhos de investigação também foram tabulados conforme a doença estudada, e a mais estudada foi pênfigo foliáceo (29,73%). CONCLUSÃO: O aumento do número de publicações nos últimos anos é alentador, mas ainda pequeno comparado ao número de artigos publicados nesses periódicos.

BACKGROUND: The qualitative and quantitative scientific output of Brazilian dermatologists in journals of high impact factor is little known. OBJECTIVE: To describe the scientific output of dermatologists from Brazilian institutions in journals of high impact factor. METHODS: The five journals with the highest impact factor in dermatology were analyzed. All articles produced from Brazilian institutions between 1986 and 2010 were compiled and the following aspects were analyzed: position of Brazilian researchers in the list of authors, selected theme, experimental design, studied disease, area of interest and year of publication. RESULTS: Seventy-four articles written with the participation of Brazilian dermatologists have been identified. Upon grouping the articles in five-year periods, an important increase was observed in the Brazilian production from the year 2006 onwards. The dermatologists were placed as second authors in the majority of cases (53.66%). According to the selected theme to be studied, the majority of the articles had a laboratory focus (45.95%). The majority of the articles reported cross-sectional studies or non-controlled clinical trials (both at 17.57%), and pemphigus foliaceus was the most studied disease (29.73%). CONCLUSION: The increase in the number of publications by Brazilian dermatologists over the last years is encouraging, but it is still small in comparison to the total number of articles published in these five periodicals.
