Efeito paradoxal do tratamento de manifestacoes convulsivas desencadeadas por exercicio fisico em uma potra - Relato de caso. Revista Brasileira de Medicina Veterinaria, 33(2):95-98, 2011. Rua Presidende Wenceslau Braz, numero 670, apart. 1101. Morada do Sol, Cuiaba, 78043-508. MT, Brasil. Email: lucianelaskoski@hotmail.comNeurological disturbs, in special seizures, are rare in adult horses and are normally observed in young animals in consequence of several diseases. A foal was admitted with neurological signs characterized by seizures during exercise. A maintenance protocol with anticonvulsants was not possible to establish therefore all the drugs had aggravated the seizures even with low dosages. Restriction of physical activity was the option, leaving the animal in stall until it had reached the maturity and at this time the neurological signs had stopped.

Incidence of retromolar foramen in human mandibles: ethnic and clinical aspects

The retromolar foramen allows the passage of the neurovascular bundles that contribute to nutrition and innervation of the pulp and periodontium of the lower teeth. Knowledge of this anatomical variation may prevent complications in the anesthesia and surgical procedures in this area and serve as an anatomical landmark for ethnic identification. The aim of this study was to evaluate the impact of the retromolar foramen in human mandibles of adult Brazilians and discuss the clinical and ethnic related to the presence of this foramen. Were evaluated 222 human mandibles, dry, adults, Brazilians, independent of gender. The evaluation was performed by two examiners who standardized search from a previous anatomical study. The mandibles were analyzed: the presence of the retromolar foramen (bilateral or unilateral), the presence of the foramen on right and left sides, and the number of foramens present on each side. It was found that 59 had at least one mandible retromolar foramens resulting in an incidence of 26.58%. The retromolar foramen was present unilaterally in 41 mandibles and 18 bilaterally, with incidences of 18.47% and 12.16% respectively. on the right side, the retromolar foramen was present in incidences of 16.22% and 18.92% respectively The analysis of the right side of the mandibles revealed that 47.46%, 21.21% and 3.03% had one, two and three foramens, respectively The left side showed 55.93%, 16.22% and 8.11% of the 222 mandibles with one, two and three retromolar foramens, respectively The incidence of retromolar foramen in the Brazilian population is significant and should be considered in the planning and execution of procedures in several areas of clinical practice dentistry in order to avoid complications. Moreover, it was found that the incidence of retromolar foramen contributes to differentiation of ethnic groups in the area of forensic anthropology.

Análise qualitativa do conteúdo ministrado na disciplina de bioética nas faculdades de odontologia brasileiras

The study consists on a qualitative analysis of content ministered by Bioethical discipline on Brazilian Dental Schools. Data collect occurred by semi-structured questioners send by e-mail and correspondence. It was used content analysis by categorical analysis technique, according to Bardin. Among 182 Schools, just 57 (31.3%) shows Bioethical Discipline. It was observed that the discipline is ministered on the first or last year of course generally. Principal subjects broached are bioethical dilemma (76.3%) with polemics questions and others actual like abortion, clone, organs transplant, attendance of patient porter of HIV and bioethical historic (65.8%), bioethical fundaments, principles and models (57.9%). 84.4% researched professors, said that bioethical discipline awake interesting on students because it actual and it's face to patient-professional relation too. It was possible to conclude that bioethical discipline treat in its content some actual and polemic themes that influence dental surgeon formation because promote him conscience and responsibility of him role front attention at oral health, and so, this discipline should be implanted, specifically in the first year of all Dentistry graduation courses.

Location of the mandibular foramen according to the amount of dental alveoli

The aim of this study was to analyze the anatomotopographic location of the mandibular foramen in the right and left ramus, and to verify the influence of the amount of dental alveoli on the foramen position. Thirty-five adult dry human mandibles of Araraquara Dental School, UNESP - São Paulo State University were assessed, with or without dental alveoli. Measurements were obtained, using a ruler and a digital caliper. The following distances were measured: Fl - distance between the lowest point of the mandibular incisure and the mandibular foramen (F point); FB - distance between the mandibular base and F point; FP - distance between the posterior margin of the ramus and F point; FA - distance between the anterior margin of the ramus and F point; FT - distance between the apex of the retromolar trigone and F point. The Mann-Whitney test was used to compare each measurement according to hemi-arch, and the Kruskal-Wallis test was used to analyze the influence of the presence of alveoli on the measures. For multiple comparison, Dunn's method was used. There was no statistically significant difference in the location of the mandibular foramen when compared to the right and left hemi-arches. The amount of dental alveoli influenced, significantly, only on FA and FP distances. Thus, it was concluded that the right and left mandibular ramus showed symmetry in the location of the mandibular foramen, and the amount of alveoli influenced on the distances of the anterior and posterior margins of the mandibular rams, in relation to the mandibular foramen.

Babesia spp. infection in dogs from rural areas of São Paulo State, Brazil

The status of Babesia spp. infection in dogs from rural areas of São Paulo State, Brazil was Studied. For this, l 50 animals were examined by blood smears and by PCR; the presence of tick infestation was also investigated. By the blood smear examination, 3 animals (2%) were detected positive and by PCR for Babesia spp. 12 (8%) were positive, with bands Visualized in 450 bp. Rhipicephalus sanguineus or Amblyomma spp. were found on 36 (24%) of the 150 dogs. Amblyomma species found were A. cajennense (9/36-25%) and A. ovale (9/36-25%). It was not possible to correlate the presence of R. sanguineus and the infection with Babesia spp. The sequencing of four positive samples demonstrated close identity with B. canis vogeli already characterized in Brazil.

Phlebotomine (Diptera: Psychodidae) survey and some considerations about epidemiological aspects of canine leishmaniasis in Rio Claro city, São Paulo, Brazil.

Between 2000 and 2004, 170 sand flies were captured in urban or peri-urban areas of the Rio Claro city, SP, Brazil. Nyssomyia neivai, the main LTA vector species in São Paulo territory, corresponded to 124 specimens (72,94%) of the total number of captured insects. Incidence of American Cutaneous (LTA) and Visceral leishmaniasis (LVA) is increasing in human and dogs in São Paulo State. Rio Claro city is located in the center-east region of the State. During 2001 and 2003, two cases of alochtonus canine LVA and an autochthonous case of canine LTA were locally diagnosed. Results indicate the risk of LVA establishment in this region. Possible role of alternative vectors in leishmaniasis transmission is discussed.

Experiences of family members regarding the oral health care of children

Este estudo objetivou verificar a compreensão das experiências dos familiares em relação ao cuidado com a saúde bucal das crianças. É estudo qualitativo, realizado em 2007, em distrito de saúde do município de Ribeirão Preto, SP, com 12 cuidadores. Utilizou-se referencial teórico da vulnerabilidade e a perspectiva hermenêutica. Três categorias empíricas foram elaboradas: os significados do cuidado com a saúde bucal, em busca das causas e da prevenção de agravos bucais e a realidade dos serviços de saúde bucal. Entre outros elementos potencializadores da vulnerabilidade infantil aos agravos bucais, emergiu a supervalorização da causalidade biológica, do atendimento de alta complexidade e da odontologia estética e, entre os protetores, a valorização do saber popular e a integração de ações e conhecimentos profissionais. Aponta-se para a revisão das estratégias de prevenção e promoção de saúde bucal, fornecendo elementos para auxiliar os serviços de saúde a reorganizarem o cuidado com a saúde bucal de crianças.

Concepções de qualidade de ensino dos coordenadores de graduação: uma análise dos cursos de odontologia do Estado de São Paulo

As novas demandas sociais e as diretrizes curriculares brasileiras para os cursos de odontologia colocam desafios à prática docente nas instituições de educação superior. Nesse contexto, investigam-se as concepções de qualidade de ensino universitário de professores que atuam como coordenadores de graduação nas faculdades de odontologia do Estado de São Paulo que possuem pós-graduação stricto-sensu, para refletir sobre os desafios da formação docente na área. Como instrumentos de levantamento de dados utilizou-se questionário, contendo perguntas abertas e fechadas e entrevista semi-estruturada, organizada para possibilitar o aprofundamento da discussão. Os dados foram descritos e discutidos mediante análise quantitativa e qualitativa, a partir das três dimensões da prática docente analisadas por Cunha (1995): político-estrutural, curricular e pedagógica. Para este artigo, focalizaram-se apenas os aspectos da dimensão pedagógica, na qual os pontos que expressam posturas mais contraditórias referem-se a métodos de ensino-aprendizagem, participação do aluno e tutoria. Os resultados apontam para concepções de ensino-aprendizagem que oscilam entre modelos tradicionais e inovadores, sinalizando pontos de conflito em relação a paradigmas que se articulam diretamente a questões curriculares e político-estruturais.

Repetibilidade de resposta superovulatória em vacas de raça Holandesa

The purpose of this study was to estimate the repeatability of transferable embryos in Holstein cows and to evaluate the effects of the year, season and order of the superovulation on the number of total structures, transferable embryos, non-transferable embryos and ovules. Four hundred and eighty-six superovulations were used in the analysis. The year of superovulation affected significantly all traits (P<0.01); however, we did not find effects of the season of the year. Superovulation order affected the total structures (P<0.01) and non-transferable embryos (P<0.05). The repeatability of the transferable embryo was 0.28 +/- 0.05. Positive correlations were found among total structures and transferable embryos (0.73) and total structure and ovule (0.51).

Uso da ciclofosfamida em modelo de imunodepressão experimental em ovinos

Cyclophosphamide (CY) was used to evaluate the effect on the immune system of sheep. Castred adult rams were divided into 3 groups, with 6 animals each one. Group I (day 0) and Group II (day 1) were treated with CY (40 mg/kg, single dose, IV), and Group III was not treated and remained as control. All groups were immunized on day 0 with B19 brucellosis vaccine. on day 6, all animals were bled and serum agglutination test for brucellosis antibodies detection was performed. During 7 days blood lymphocyte counts and electrophoresis gammaglobulin dosage were daily performed. The results showed statistical decrease of immune response. Low serum titers of brucellosis antibodies were found in Groups I and II, and lymphopenia and hypogammaglobulinemia were also found in these groups. A high mortality rate (40%) occurred in the treated animals.

Perfil sorológico anti-Brucella abortus em bezerras vacinadas com amostras B19

The serological profiles of 33 female bovines, vaccinated at three to eight months of age with the B19 standard strain of Brucella abortus, were studied over a period of 728 days, using the following agglutination procedures: plate agglutination, tube agglutination, rose bengal plate and mercaptoethanol test. Maximum levels of antibodies detected reached by the plate agglutination and tube agglutination tests were found between the 14(th) and 42(nd) day, and with mercaptoethanol test, between the 28(th) and 42(nd) day. Anti-Brucella antibodies decreased thereafter. At 182 days after vaccination, five suspected animals and one positive were detected by the plate agglutination test, while by the tube agglutination test, only one animal was suspected and another one was positive. During the same period, positive reactions were found in six animals by means of the mercaptoethanol test, and five positives by the rose bengal test. By means of tube agglutination and plate agglutination tests, the animals became serologically negative at 245 and 273 days, respectively, after the vaccination, based on the rules adopted for the vaccinated animals. Using the mercaptoethanol and rose bengal plate tests, all the animals were found to be negative at 308 days after vaccination.

Ácidos orgânicos e microbiota cecal anaeróbia no controle da infecção experimental de frangos por Salmonella typhimurium e Salmonella enteritidis

The aim of this investigation was to study the effect of organic acids and/or anaerobic cecal microflora (ACM) on systemic and digestive infection of broilers by Salmonella typhimurium and S. enteritidis. ACM was used without previous bacterial identification. The treatment with ACM increased the resistance to Salmonella spp infection. Infection was more evident in caeca, followed by rectum and crop and did not interfere on body weight of broilers. Treated and control groups showed the same degree of infection at the end of the experiment. The use of ACM isolated or combined with acetic acid, reduced the colonization of the chick's digestive system by S. typhimurium and S. enteritidis. Acetic acid added to ACM did not potentiate the reduction of digestive system colonization. Except for the crop, the isolated use of acetic, propionic or formic acids did not reduce S. typhimurium and S. enteritidis, in caeca and rectum. The use of organic acids and ACM had little effect on reduction of caecum pH. The treatment with ACM reduced the quantity of S. enteritidis in the faeces. The reduction of caecum pH did not reduce the quantity of S. enteritidis in faeces. S. enteritidis was much more invasive than S. typhimurium and use of organic acids and ACM had little effect on reduction of systemic infection.
