Lesão por pododermatite em frangos de corte alojados em diferentes densidades.

A criação avícola com uma maior densidade visa o aumento da produção, com o mínimo de investimentos em construções e otimização dos custos fixos. Em consequência, a pressão para redução dos custos na criação de frangos de corte levou ao aumento da densidade das aves que promove maior produção de peso vivo/m2 (2). Além disso, a piora na qualidade da cama, principalmente pela compactação decorrente de aumento de umidade, determina o aparecimento de lesões na pele, pododermatites, calo de peito e hematomas (4). As pododermatites de contato são lesões erosivas da pele, predominantes na superfície plantar das patas dos frangos de corte. A etiologia apresenta uma inflamação da pele devido a uma combinação de umidade e fatores cáusticos presentes na cama, sendo a excreta das aves, que é composta de ácido úrico, um agente importante na formação do problema (1). As pododermatites em frangos de corte passaram a ter maior relevância nos últimos anos devido à exportação dos pés dos frangos para os mercados da Ásia. Objetivou-se com este trabalho avaliar o efeito do aumento da densidade em aviário convencional sobre a frequência de lesões por pododermatite em frangos de corte

Intravenous lipid emulsion and dexmedetomidine for treatment of feline permethrin intoxication: A report from 4 cases

Four cases of feline permethrin intoxication are described. The cause of intoxication is the application of canine permethrin spot-on product (Advantix®, Bayer) by the owners. Principal clinical guidelines recommends the use of anticonvulsant drugs to treat seizures or neurological symptoms after initial stabilization and dermal decontamination. The use of lipid emulsion had an increasing interest in the last decade for treatment of toxicosis caused by lipophylic drugs as reported in human and in veterinary medical practices. All cats presented in this study, were treated with intravenous lipid emulsion (ILE) at variable dosages, and dexmedetomidine was also administered by intravenous way. No adverse reaction such as thrombophlebitis, overload circulation or others was noticed during and after administration of ILE. Dexmedetomidine was proved to be helpful in tranquillizing the cats. All cats were discharged in good condition faster than other cases treated without their use

Double filtration plasmapheresis in a dog with multiple myeloma and hyperviscosity syndrome

A 12 year old, 38 kg, mix-breed, intact male dog presented with a 20 day history of clinical signs consistent with hyperviscosity syndrome secondary to multiple myeloma. The dog received three double filtration plasmapheresis treatments on day 0, 7 and 22 after presentation. A significant (p<0.05) reduction in serum total protein, alpha-2 and gamma globulins was found following each treatment. These reductions were accompanied by a complete resolution, although temporary, of the clinical signs of hyperviscosity syndrome. The present study reported for the first time the use of double filtration plasmapheresis to reduce clinical signs of hyperviscosity syndrome in a dog with multiple myeloma

Análise multivariada do efeito de diferentes densidades de alojamento sobre lesões podais em frangos de corte.

Este trabalho objetivou avaliar a utilização de estatísticas multivariadas para análise de um conjunto de dados com diferentes densidades de alojamento em frangos de corte. Foi conduzido um experimento com duas densidades de alojamento (11,07 e 13,21 aves/m²), e mensuradas variáveis de desempenho, qualidade de cama e incidência de lesões podais. A análise de fatores gerou 3 autovalores que acumularam 80,4% variância total dos dados. O Fator 1 (41,6% da variância) foi o único estatisticamente significativo pela análise de variância, e agrupou todas as variáveis relacionadas com umidade de cama e graus de lesão podal, mostrando haver uma inter-relação entre as mesmas. Estes dois grupos de variáveis foram utilizados na análise de componentes principais. Os dois primeiros componentes principais gerados acumularam 86,5% da variância total dos dados, e sua epresentação gráfica agrupou variáveis de umidade de cama e os graus mais severos de lesão podal com a maior densidade de alojamento. A análise multivariada utilizada foi eficiente no desdobramento das inter-relações entre as variáveis e demonstrou que o aumento da densidade de alojamento foi determinante na maior incidência de lesões por pododermatite e sua relação com a maior umidade da cama. This study aimed to evaluate the use of multivariate statistics to analyze a data set of different animal densities in broiler chickens. Was conducted an experiment with two animal densities (11.07 and 13.21 birds/m²); the variables measured were performance, litter quality and incidence of foot pad dermatitis. Factor analysis generated three eigenvalues which accumulated 80.4% of the total variance. Factor 1 (41.6 % of variance) was the only statistically significant by analysis of variance, and grouped all variables related to litter moisture and degrees of foot pad dermatitis, showing that there is a relationship between them. These two groups of variables wereused in the principal components analysis. The first two principal components generated accumulated 86.5% of the total variance of the data and their graphical representation grouped variables related to litter moisture and the most severe degrees of foot pad dermatitis with the highest density of housing. The multivariate analysis used was efficient in the deployment of inter-relationships between variab les and showed that increased housing density was determinant in the increased incidence of pododermatitis injuries and its relation to higher litter moisture

Clinical practice: neonatal resuscitation. A Dutch consensus

The updated Dutch guidelines on Neonatal Resuscitation assimilate the latest evidence in neonatal resuscitation. Important changes with regard to the 2004 guidelines and controversial issues concerning neonatal resuscitation are reviewed, and recommendations for daily practice are provided and argued in the context of the ILCOR 2005 consensus

Responsiveness to exercise training in juvenile dermatomyositis: a twin case study

<p>Abstract</p> <p>Background</p> <p>Patients with juvenile dermatomyositis (JDM) often present strong exercise intolerance and muscle weakness. However, the role of exercise training in this disease has not been investigated.</p> <p>Purpose</p> <p>this longitudinal case study reports on the effects of exercise training on a 7-year-old patient with JDM and on her unaffected monozygotic twin sister, who served as a control.</p> <p>Methods</p> <p>Both the patient who was diagnosed with JDM as well as her healthy twin underwent a 16-week exercise training program comprising aerobic and strengthening exercises. We assessed one repetition-maximum (1-RM) leg-press and bench-press strength, balance, mobility and muscle function, blood markers of inflammation and muscle enzymes, aerobic conditioning, and disease activity scores. As a result, the healthy child had an overall greater absolute strength, muscle function and aerobic conditioning compared to her JDM twin pair at baseline and after the trial. However, the twins presented comparable relative improvements in 1-RM bench press, 1-RM leg press, VO_2peak, and time-to-exhaustion. The healthy child had greater relative increments in low-back strength and handgrip, whereas the child with JDM presented a higher relative increase in ventilatory anaerobic threshold parameters and functional tests. Quality of life, inflammation, muscle damage and disease activity scores remained unchanged.</p> <p>Results and Conclusion</p> <p>this was the first report to describe the training response of a patient with non-active JDM following an exercise training regimen. The child with JDM exhibited improved strength, muscle function and aerobic conditioning without presenting an exacerbation of the disease.</p
