Occurrence of Salmonella sp. in poultry carcasses evaluated from the retail trade between 2007 and 2013 in Paraná state, Brazil / Ocorrência de Salmonella sp. em carcaças de frango avaliadas a partir do comércio varejista entre 2007 e 2013 no estado do Paraná, Brasil

Poultry meat is often involved as a vehicle for microorganisms that cause food-borne diseases. Salmonella sp. is a major pathogen involved in outbreaks around the world. Based on its importance, the objective of this study was to determine the occurrence of Salmonella sp. in frozen and chilled poultry carcasses slaughtered and marketed in the western region of Paraná state, Brazil. A total of 340 samples were collected between January 2007 and April 2013, with 66 (19.41%) carcasses positive for Salmonella sp. It can be concluded from the results obtained that the occurrence of Salmonella sp. in poultry carcasses remains high, even though it is a product marketed refrigerated or frozen, methods considered appropriate for food preservation. A lower occurrence result was expected due to the 14-year implementation of the national pathogen reduction program established by the Ministry of Agriculture, Livestock and Supply aimed at a gradual reduction in the occurrence of Salmonella sp. in these products through constant monitoring of carcasses immediately after slaughter.(AU)

A carne de aves é um alimento que frequentemente encontra-se envolvido como veículo de micro-organismos causadores de enfermidades, sendo Salmonella sp. um desses agentes comumente envolvidos nessas enfermidades em todo o mundo. Com isso, o objetivo deste estudo foi determinar a ocorrência de Salmonella sp. em carcaças de frango congeladas e refrigeradas, abatidas e comercializadas na região oeste do estado do Paraná. Um total de 340 amostras foram coletadas entre janeiro de 2007 e abril de 2013. Das amostras analisadas, 66 (19,41%) das carcaças foram positivas para Salmonella sp. De acordo com os resultados obtidos pode-se concluir que a ocorrência de Salmonella sp. em carcaças de frangos permanece alta, mesmo sendo produtos comercializados refrigerados ou congelados, métodos considerados adequados para conservação de alimentos. Um resultado de menor ocorrência era esperado devido à implementação de 14 anos do Programa Nacional de Redução de Patógenos estabelecido pelo Ministério da Agricultura, Pecuária e Abastecimento visando uma redução gradual na ocorrência de Salmonella sp. nestes produtos através de monitoramento constante de carcaças imediatamente após o abate.(AU)

Revision rhinoplasty: physician-patient aesthetic and functional evaluation / Revision rhinoplasty: physician-patient aesthetic and functional evaluation

Abstract Introduction: Approximately 5-15% of patients submitted to rhinoplasty operations undergo revision surgery. Those patients have varied functional and aesthetic complaints that should receive a detailed assessment that includes all the expectations the patient had before the previous procedure. Objective: To draw the profile of the main aesthetic-functional complaints reported by patients to be submitted to revision rhinoplasty and to correlate them with the internal and external objective nasal evaluation performed by the surgeon. Methods: A prospective study was conducted with 43 patients to be submitted to revision rhinoplasty and their respective surgeons, by applying a questionnaire about the patients' epidemiological questions and subjective aesthetic-functional complaints as well as the respective functional deformities observed by the surgeons. Subsequently, these data were correlated with the purpose of observing the frequency of congruent reports between physicians and patients. Results: The presence of drooping tip and residual bridge hump were the patients' main complaints, confirmed by the surgeons. The correlation between subjective obstructive symptoms and the intranasal evaluation performed by surgeons was shown to be present in 87.5% of the cases. Among the patients with respiratory symptoms, the main deformity identified was residual septal deviation in 56.25% of the cases. Conclusion: The drooping tip followed by residual hump were the main complaints reported by the patients and confirmed by the objective examination by the physicians. The presence of nasal obstructive complaints in 37.2% of the patients shows that greater attention needs to be paid to functional deformities during the first surgical procedure. The differences observed between patients' complaints and surgeons' evaluations confirm the need for detailed assessment and clarification to the patients regarding their expectations and actual surgical possibilities.

Resumo: Introdução: As rinoplastias possuem índice de revisão em torno de 5% a 15% dos pacientes operados. Tais pacientes possuem queixas funcionais e estéticas variadas e a avaliação detalhada é de extrema importância, tendo em vista todas as expectativas em torno de um procedimento já anteriormente realizado. Objetivo: Traçar o perfil das principais queixas estético-funcionais referidas pelo paciente a ser submetido à rinoplastia revisional e correlacioná-las a avaliação nasal objetiva interna e externa realizada pelo cirurgião. Método: Foi realizado um estudo prospectivo com 43 pacientes a serem submetidos à rinoplastia revisional e com seus respectivos cirurgiões, através da aplicação de questionário acerca de questões epidemiológicas e queixas estético-funcionais subjetivas dos pacientes e as respectivas deformidades funcionais observadas pelos cirurgiões. Após, esses dados foram correlacionados com a finalidade de observar a frequência de relatos concomitantes entre os médicos e pacientes. Resultados: A presença de ponta caída e giba óssea residual foram as principais queixas dos pacientes confirmadas pelos cirurgiões. Já a correlação entre sintomas subjetivos obstrutivos e a avaliação intranasal realizada pelos cirurgiões demonstrou estar presente em 87,5% dos casos. Dentre os pacientes com sintomas respiratórios, a principal deformidade encontrada foi o desvio septal residual em 56,25% dos casos. Conclusão: A ponta caída seguida de giba óssea residual foram as principais queixas relatadas pelos pacientes e confirmadas ao exame objetivo pelos médicos. A presença de 37,2% dos pacientes com queixas obstrutivas nasais demonstra que maior atenção deve ser dada a deformidades funcionais já durante o primeiro procedimento cirúrgico. As diferenças observadas entre as queixas dos pacientes e avaliações dos cirurgiões comprovam a necessidade da avaliação pormenorizada e esclarecimento ao paciente com relação as suas expectativas e reais possibilidades cirúrgicas.

Multidrug resistance and ESBL-producing Salmonella spp. isolated from broiler processing plants

Abstract The aim of this study was to investigate the occurrence of multidrug-resistant, extended spectrum beta-lactamase (ESBL) producing Salmonella spp. isolated from conveyor belts of broiler cutting rooms in Brazilian broiler processing plants. Ninety-eight strains of Salmonella spp. were analyzed. Multidrug resistance was determined by the disk diffusion test and the susceptibility of the isolated bacteria was evaluated against 18 antimicrobials from seven different classes. The double disk diffusion test was used to evaluate ESBL production. Of the 98 strains tested, 84 were multidrug resistant. The highest rates of resistance were against nalidixic acid (95%), tetracycline (91%), and the beta-lactams: ampicillin and cefachlor (45%), followed by streptomycin and gentamicin with 19% and 15% of strain resistance, respectively. By contrast, 97% of the strains were sensitive to chloramphenicol. 45% of the strains were positive for the presence of ESBL activity. In this study, high rates of multidrug resistance and ESBL production were observed in Salmonella spp.

Condições de comercialização de produtos de origem animal em feiras livres de municípios da região oeste do Paraná

O objetivo deste trabalho foi constatar a situação higienicossanitária de barracas de feiras livres localizadas em cinco municípios da região oeste do Paraná e a qualidade microbiológica e físico-química dos produtos nelas comercializados. Entre fevereiro e maio de 2013, foram realizadas avaliações, por meio do uso de checklist em 52 barracas onde foram adquiridas 71 amostras sendo estas submetidas à análise microbiológica e/ou físico-química. Foi constatado que em 47,9% das barracas o armazenamento dos alimentos era realizado de forma inadequada, que 86% dos produtos de origem animal estavam acondicionados em embalagens impróprias e que em 65% das mesmas, a condição higiênica dos manipuladores foi classificada como "Regular". Foram encontradas não conformidades em 36,6% das amostras submetidas às análises microbiológicas e/ou físico-químicas, sendo detectada a presença de Salmonella sp. em uma amostra de linguiça colonial. Sendo assim, é necessário que haja um controle sanitário na produção e comércio dos produtos nestas feiras por parte dos órgãos públicos responsáveis, garantindo assim, a segurança alimentar do consumidor.

The objective of this study was to determine the hygiene conditions of street market stands that sell products of animal origin in five cities in western Parana, Brazil, as well as the microbiological and physical-chemical quality of the products that are sold there. Between February and May, 2013, a total of 52 street market stands were analyzed based on a checklist. 71 samples were collected in these stands and submitted to microbiological and/or physical-chemical analyses. It was observed that in 47.9% of the stands, food products were inadequately stored; 86% of the products of animal origin were kept in improper containers; and in 65% of the stands, handler hygiene was classified as regular. 36.6% samples did not comply with microbiological and/or physical-chemical standards, with one sample of colonial sausage showing the presence of Salmonella sp. Therefore, public organisms control of hygiene in the production and commercialization of products in street markets is highly necessary to ensure food safety.
