Patient Education and Self-Care for the Management of Jaw Pain upon Awakening: A Randomized Controlled Clinical Trial Comparing the Effectiveness of Adding Pharmacologic Treatment with Cyclobenzaprine or Tizanidine

Aims: To compare the effectiveness of adding cyclobenzaprine, tizanidine, or placebo to patient education and a self-care management program for patients with myofascial pain and specifically presenting with jaw pain upon awakening. Methods: Forty-five patients with a diagnosis of myofascial pain based on the guidelines of the American Academy of Orofacial Pain participated in this 3-week study. The subjects were randomly assigned into one of three groups: placebo group, TZA group (tizanidine 4 mg), or CYC group (cyclobenzaprine 10 mg). Patients were evaluated for changes in pain intensity, frequency, and duration by using the modified Severity Symptoms Index and changes in sleep quality with the use of the Pittsburgh Sleep Quality Index. Data were analyzed by ANOVA and post-hoc or nonparametric statistical tests as appropriate. Results: All three groups had a reduction in pain symptoms and improvement of sleep quality based on a comparison of pretreatment and treatment scores. However, no significant differences among the groups were observed at the posttreatment evaluation. Conclusion: The use of tizanidine or cyclobenzaprine in addition to self-care management and patient education was not more effective than placebo for the management of patients with myofascial jaw pain upon awakening.

Variabilidade espacial de populações de Diatraea saccharalis em canaviais e sugestão de método de amostragem

A broca Diatraea saccharalis é uma das mais importantes pragas da cana-de-açúcar no Brasil. O manejo de áreas infestadas está embasado no controle biológico com Cotesia flavipes, cujas liberações são feitas em função da população de lagartas da praga em campo. Por esta razão, a estimativa desta população é de fundamental importância para o sucesso do programa de manejo. Assim, o objetivo do presente trabalho foi estudar a variabilidade espacial de D. saccharalis em canaviais e sugerir um método de amostragem que permitisse uma estimativa adequada das populações em campo. Seis campos de aproximadamente 1 ha cada um foram amostrados, em grid retangular de aproximadamente 10 x 10 m, com ilhas. Cada ponto de amostragem foi representado pela coleta das formas biológicas da praga no interior dos colmos em 2 m de sulco. Na maioria das áreas, as populações de formas imaturas de D. saccharalis distribuíram-se de forma contagiosa, com alcance do semivariograma variando de 18 a 80 m. Com base no alcance médio, estimou-se em seis o número médio de pontos de amostragem por hectare que deveriam ser feitos para representar adequadamente a área. Este número foi menor do que o estimado utilizando parâmetros da estatística clássica. Sugere-se que, para estimativa das formas imaturas de D. saccharalis em canaviais, a amostragem seja feita em grid de 40 x 40 m, o que resulta em aproximadamente seis pontos de amostragem por hectare e permitirá, na maioria das áreas, efetuar levantamentos com independência e coeficientes de variação menores que 50%.

Dispersão de Orthezia praelonga Douglas, 1891 (Hemiptera: Ortheziidae) causada por equipamentos de pulverização em pomar de citros

A cochonilha O. praelonga é considerada uma importante praga dos citros no Brasil, e informações sobre a sua dispersão estão baseadas apenas em observações empíricas. Objetivou-se avaliar o efeito de equipamentos de pulverização comumente utilizados pelos citricultores na dispersão da praga. Armadilhas adesivas foram instaladas no solo e em vergalhões dispostos verticalmente às plantas de três linhas adjacentes em um talhão de citros contendo plantas infestadas pela praga. Foram adotados equipamentos utilizados para controle de pragas dos citros. A avaliação da dispersão foi realizada por meio da contagem de fêmeas, ninfas ou partes dos insetos aderidas às armadilhas adesivas. Os equipamentos Martignani e Bié foram capazes de lançar a praga a até 15 m, enquanto, para o equipamento Turbo Valência, detectaram-se fragmentos cerosos a até 22 m da máquina. Os equipamentos dotados de pistola não causaram qualquer dispersão da praga. Portanto, evidenciou-se que mesmo a utilização de equipamentos para controle de outras pragas pode favorecer a dispersão da cochonilha O. praelonga em pomares de citros, e isso deve ser considerado no aprimoramento do programa de manejo integrado de pragas dos citros.

Preferência alimentar da formiga urbana Camponotus vittatus forel (Hymenoptera: Formicidae)

For an adequate management program of urban ants, knowledge on their biology is required, with the aim of detecting and exploring their vulnerabilities. This type of information has been used in the manufacture of baits, which must show, among other characteristics, attractiveness to several species to be considered efficient and economically viable. Therefore, the present study was aimed to evaluate in the laboratory the attractiveness of sweet and fatty substances to Camponotus vittatus, trying to find which substances would be more efficient to be introduced as the attractive component in baits. Five colonies, 68 sweet substances and 23 fatty substances were utilized in the laboratory trials. The most attractive sweet and fatty substances, were, respectively, 75% demerara sugar and vegetable fat. When substances of both natures were tested together, sweet substances presented slightly higher attractive indexes than oily substances.

Popcorn (Zea mays L. var. everta) yield and yield components as influenced by the timing of broadcast flaming

Farmers are interested in producing popcorn under organic production systems and propane flaming could be a significant component of an integrated weed management program. The objective of this study was to collect baseline information on popcorn tolerance to broadcast flaming as influenced by propane dose and crop growth stage at the time of flaming. Field experiments were conducted at the Haskell Agricultural Laboratory of the University of Nebraska, Concord, NE in 2008 and 2009 using five propane doses (0, 13, 24, 44 and 85 kg ha(-1)) applied at the 2-leaf, 5-leaf and 7-leaf growth stages. Propane was applied using a custom-built research flamer driven at a constant speed of 6.4 km h(-1). Crop response to propane dose was described by log-logistic models on the basis of visual estimates of crop injury, yield components (plants m(-2), ears plant(-1), kernels cob(-1) and 100-kernel weight) and grain yield. Popcorn response to flaming was influenced by the crop growth stage and propane dose. Based on various parameters evaluated, popcorn flamed at the 5-leaf showed the highest tolerance while the 2-leaf was the most susceptible stage. The maximum yield reductions were 45%, 9% and 16% for the 2-leaf, 5-leaf and 7-leaf stages, respectively. In addition, propane doses that resulted in a 5% yield loss were 23 kg ha(-1) for the 2-leaf and 7-leaf and 30 kg ha(-1) for the 5-leaf stage. Flaming has a potential to be used effectively in organic popcorn production if properly used. (C) 2010 Elsevier Ltd. All rights reserved.

Alternativas para o controle de nematoides gastrintestinais de pequenos ruminantes

Sheep and goat farming requires an efficient management program, due to losses caused by parasites in susceptible animals. Many factors may collaborate to improve infection tolerance in the herd, such as: genetics, nutrition, physiological status, and age. The problem caused by resistance to antihelmintic agents has led to the spread of alternative techniques for parasite controls. The latest strategies include selective treatment with the FAMACHA method, phytotherapy, biological control with predatory fungi, and strategies that still await scientific confirmation, such as homeopathy, the dilution of resistance with the introduction of susceptible parasites, and the combination of drugs without antihelmintic effect. The main objective of these methods is to reduce the usage of antiparasitic agents, thus slowing the development of resistance and promoting the better use of effective products and newly released products. The objective of this article is to describe techniques for controlling nematodes in small ruminants, and it is aimed at technicians interested in increasing their knowledge about the mechanisms of resistance to antihelmintic agents as well as alternatives to the use of these products.

Greening the campus of a Brazilian university: cultural challenges

Purpose - This study examined the relationship between environmental management practices developed at a campus of a Brazilian university (University of Sao Paulo) and the greening of its organizational culture. The paper aims to discuss these issues.Design/methodology/approach - This article presents a theoretical background based on the concepts of environmental management, organizational culture and environmental management in higher education institutions. The main framework of this research is the model proposed by Harris and Crane.Findings - The studied university has an environmental management program that is sometimes constrained in the following ways: the university bureaucracy and hierarchy; the main performance indicators for lecturers and professors are based on scientific production and publication, giving them little time for complementary activities; and some units develop their own environmental management practices, but they are not disseminated as best practices for use by other units. Some academic units showcase the proactive actions of professors who incorporate environmental management into their daily activities. The general perception is that the phrase environmental management is almost synonymous with solid waste management.Originality/value - This research details the first Brazilian application of the Harris and Crane model. It contributes an original analysis of environmental management and green organizational culture of a Brazilian university, an organizational type that has seldom been studied to date.
