Entre os métodos de controle da verminose gastrintestinal em ovinos, a utilização de produtos químicos é o mais empregado. Porém, o uso indiscriminado e continuado desses produtos tem selecionado populações de helmintos resistentes aos anti-helmínticos, fenômeno relatado no mundo todo. Este trabalho teve como objetivo identificar as espécies de parasitos gastrintestinais e diagnosticar a situação da resistência anti-helmíntica em ovinos no Estado de Mato Grosso do Sul. Foram realizados testes de redução na contagem de ovos por grama de fezes (OPG) em rebanhos de dezesseis propriedades rurais; as sete formulações utilizadas continham as seguintes bases farmacológicas: Albendazol, Ivermectina, Levamisole, Triclorfon, Moxidectina, Closantel e uma contendo as três primeiras associadas. As espécies identificadas nas necropsias, em ovinos adultos, foram: Haemonchus contortus, Trichostrongylus colubriformis, Cooperia curticei, C. punctata, C. pectinata e Oesophagostomum columbianum; em ordem de prevalência. As formulações contendo Albendazol e Ivermectina não apresentaram eficácia na redução de OPG nos rebanhos testados, com médias de redução de 0,7 e -19,6%, respectivamente. Closantel apresentou eficácia média de 6,7%; Levamisole, Moxidectina e Triclorfon de 28,7, 26,8 e 65%, respectivamente; a associação das três bases (Albendazol, Ivermectina e Levamisole), uma média de eficácia de 55,8%. As percentagens médias de larvas infectantes recuperadas nas coproculturas, tanto no pré como no pós-tratamento, foram semelhantes; indicando que a resistência às bases testadas está presente em todas as espécies citadas, em maior ou menor intensidade. Os dois gêneros predominantemente resistentes são Haemonchus sp., com 86,9%; seguido por Trichostrongylus sp., com média de 47,5%; Strongyloides sp. 33,6%; Oesophagostomum, sp. 21,4% e Cooperia sp. 19,7%.

The effect of electrical discharges without thermic effect and of energy field on Meloidogyne incognita Rara 1 larvae elimination in weir water was tested. on an average, 63,22% of larvae were killed by electrical discharges, in comparison with 53,12% of dead larvae in the control (water that received only ammonium sulphate) as an electrolyte. Water exposed to energy fields presented higher percentages of dead larvae (50,01% for electromagnetic field, 43,78% for variable electric field and 40,48% for static electric field) in comparison with control, represented by water without exposition to any energy field and without ammonium sulphate (34,27%).

The individual affective-cognitive evaluations are important factors that control the way he feels the disease impact in his life. Then, the perception of seizure control is a more important factor to evaluate Quality of Life (QoL) than the illness characteristics, such as the severity, type, sickening period and seizure frequency. This study searched for the relationship among the subjective variables (perception of seizure control) and the illness characteristics to evaluate QoL. The sample consisted of 60 individuals with chronic epilepsy, aging 18 to 70 (M=37.05; SD=11.25), chosen at randon from the ambulatory of epilepsy - HC/UNICAMP, by the Questionnaire 65. The illness characteristics were not significant, except the seizures frequency, when associated to the impairment in QoL among controlled seizures and seizures with frequency higher than 10 per month (p=0.021). The perception of control was significantly associated to QoL (p=0.005).

The aim of this study was to test fear, anxiety and control related to dental treatment. The subjects were 364 children with ages between 7 and 13 years. Three questionnaires with multiple choice questions were applied in groups of 10 children. The first instrument was the 15-item dental subscale from the Childrens Fear Survey Schedule9. The subjects rated their level of fear on a 5-point scale. The second survey instrument was the 20-item subscale from the State Trait Anxiety Inventory for Children16. This measure was used to capture how anxious the child was, in general. The third instrument was the Child Dental Control Assessment19. It contained 20 items to assess perceived control and 20 items to assess desired control. The results of the survey indicated that dental fear and anxiety were slightly higher for females when compared with male subjects (P < 0.05). Older children (11 to 13 years old) obtained higher fear scores than younger ones (7 to 9 years old). Concerning perceived control, the results indicate that younger children perceive more control than older ones. For desired control, the results indicate that younger children reported higher percentages than older ones. In this study, patients who had undergone anesthesia during treatment revealed higher fear scores when compared with those who had not. Dental fear etiology seems to be related to a procedure that may involve pain or lack of control.
