A Stereophotogrammetry Face Study Between Dentate and Edentulous Adults Rehabilitated with Either a Conventional Complete or an Implant-Supported Fixed Complete Denture.

Quantifying in edentulous patients the facial collapse and whether complete conventional denture (CCD) and implant-supported fixed complete denture (ISFCD) can restore the facial proportions to match those of a dentate patient (CG) is relevant for clinical dentists. One hundred and four participants were enrolled and divided into edentulous (n=56) and CG (n=48). The edentulous participants were rehabilitated with CCD (n=28) or ISFCD (n=28) in both arches. Anthropometric landmarks in the face were marked and captured by stereophotogrammetry. Linear, angular, and surface measurements were analyzed and compared among groups. The statistical analysis was performed by an independent t-test, the one-way ANOVA, and Tukey's test. The significance level was set at 0.05. The facial collapse was quantified as a significant shortening of the lower third of the face affecting facial aesthetics in all parameters evaluated and the same was observed in comparison among CCD, ISFCD, and CG. The CCD presented statistical differences with the CG group in the lower third of the face and labial surface, and the ISFCD showed no statistical differences with the CG and CCD. The facial collapse in edentulous patients could be restored through oral rehabilitation with an ISFCD similar to those of dentate patients.

Use of external nasal strip influences alveolar cell population of horses after exercise / Uso de fita nasal influencia a população de células alveolares em equinos após exercício

The nasal strip is widely used in horses during exercise, but effects of using a nasal strip are controversial and little is known about its effect on horses undergoing endurance events. The aim of this study was to determine whether the use of nasal strips influences alveolar cell population assessed by bronchoalveolar lavage (BAL), tidal volume, and nasal airflow rate. Six Arabian horses were subjected to two low intensity tests on a treadmill, with and without application of a commercial external nasal strip. Tidal volumes and airflow rates were measured during the test; two hours after the test, BAL was performed to assess cytology of pulmonary secretions. The lavage fluid showed increased neutrophil count after exercise in animals with the nasal strip (P<0.05). This suggests that turbulence of airflow through the nasal cavity may have diminished with nasal strip use, thus allowing larger particles to be deposited more distally in the respiratory system, inducing a more intense neutrophilic response. No differences in tidal volumes or airflow rates were observed between groups (with or without nasal strips) during the test (P>0.05). The use of nasal strips seems to influence alveolar cell population during and after exercise in horses after low intensity exercise tests. Further studies are needed to verify whether alveolar cell population is related to poor exercise performance in horses.(AU)

A fita nasal é amplamente utilizada em equinos durante o exercício, porém seus resultados são controversos e pouco conhecidos em animais que disputam provas de resistência. O objetivo deste trabalho foi verificar se o uso da fita nasal influencia a população de células alveolares por meio de lavado broncoalveolar, volume corrente e fluxo de ar nasal. Foram utilizados seis equinos da raça Árabe, que realizaram dois testes de longa duração em esteira, sendo um teste com a fita e outro sem a fita nasal. Fluxo e volume respiratório foram mensurados durante o teste; duas horas após o término do exercício, foi realizado lavado broncoalveolar para realização de citologia da secreção pulmonar. Foi verificada maior porcentagem de neutrófilos após o exercício nos animais que se exercitaram com a fita nasal (P<0,05), indicando que o turbilhonamento na passagem do ar através da cavidade nasal pode ter diminuído, permitindo que partículas maiores se depositassem em porções mais distais do sistema respiratório, induzindo uma resposta neutrofílica mais intensa. Não houve diferenças entre os parâmetros ventilatórios analisados entre os animais quando correram com ou sem a fita nasal (P>0,05). O uso da fita nasal parece influenciar alguns parâmetros, durante e após o exercício, em animais que realizam provas de longa duração. Outros estudos devem ser realizados para verificar se essa influência pode melhorar o desempenho desses animais em exercícios predominantemente aeróbicos.(AU)

Serum protein profile as a biomarker in diagnosing leishmaniosis and monocytic ehrlichiosis in dogs / Perfil sérico de proteínas como biomarcador nos diagnósticos da leishmaniose e da erliquiose monocítica em cães

Diagnosing Canine Visceral Leishmaniosis is challenging for veterinarians given that its hematological and biochemical abnormalities greatly resemble those of other illnesses of dogs, such as canine ehrlichiosis, which is caused by Ehrlichia canis and is highly prevalent with high pathogenicity. The aim of this study was to determine occurrences of serological positivity for the antigens of Ehrlichia canis and Leishmania infantum and its relationship to globulin concentrations in samples from dogs. Out of 93 samples tested, 12.9% were negative for the antigens of both L. infantum and E. canis; 33.3% were seropositive for both antigens. Discordant results were found from 18.3% that were positive only for L. infantum, while 35.5% were positive only for E. canis. Hyperglobulinemia was observed in 88.2% and the statistical analysis showed that there was a significant relationship between the high levels of globulins and seropositivity for the antigen of E. canis. However, the relationship between positivity for the antigen of L. infantum and hyperglobulinemia, showed that there was no statistically significant relationship between the two laboratory findings. From these results, it can be concluded that concomitant infections occur frequently and that hyperglobulinemia is more closely related to ehrlichiosis than to leishmaniosis, in dogs.

O diagnóstico da leishmaniose canina é um desafio ao Médico Veterinário visto que anormalidades hematológicas e bioquímicas muito se assemelham à outras enfermidades dos cães, como a erliquiose canina, causada pela Ehrlichia canis, muito prevalente e de alta patogenicidade. O objetivo deste estudo foi determinar a positividade sorológica frente aos antígenos de Ehrlichia canis e Leishmania infantum e a sua relação com as concentrações de globulinas em amostras de cães. Das 93 amostras testadas, 12,9% foram negativas frente aos antígenos de E. canis e L. infantum e 33% foram soropositivas. Resultados discordantes foram encontradas em 18,3% positivas apenas para L. infantum, enquanto que 35,5% reagiram apenas frente a E. canis. Hiperglobulinemia foi observada em 88,2% das amostras e a análise estatística mostrou haver relação significante entre a soropositividade frente aos antígenos de E. canis e a hiperglobulinemia, e em contrapartida, a relação entre esse aumento de globulinas e a positividade para L. infantum foi insignificante. Pelos resultados apresentados, pode-se concluir que as infecções concomitantes são frequentes e que a hiperglobulinemia está mais intimamente relacionada a erliquiose quando comparada à leishmaniose em cães.

Epidemiologia e avaliação de risco associado à presença de ácaros hematófagos em galpões de granjas avícolas de postura / [Epidemiological and risk assessment associated with the presence of hematophagous mites in poultry farms]

Este estudo teve como objetivo caracterizar a epidemiologia da presença de ácaros hematófagos em granjas de postura no estado de Minas Gerais. Foi utilizado um banco de dados secundário, com informações de 402 galpões de 42 propriedades comerciais. As variáveis utilizadas para compor o modelo de correspondência foram selecionadas por meio do teste qui-quadrado (P≤0,05). Foi construído um índice para a presença de ácaros hematófagos, considerando alguns fatores de risco. Além disso, um estudo da análise espacial foi realizado para avaliar a presença de ácaros hematófagos em Minas Gerais. Observou-se a presença de ácaros hematófagos em 48% dos galpões, sendo a de O. sylviarum de 45,5%, O. bursa de 17,4% e D. gallinae de 2,7%. Houve associação entre o índice de risco com os intervalos de remoção de fezes e com a presença ou a ausência de aves sinantrópicas. Verificou-se que granjas mais tecnificadas não utilizam acaricida em seus galpões. A presença de ácaros hematófagos foi observada na mesorregião Sul/Sudoeste de Minas Gerais e entre as mesorregiões Oeste de Minas e Metropolitana de Belo Horizonte. Esses resultados fornecem conhecimento sobre a epidemiologia desses ectoparasitos e podem contribuir na tomada de decisões, reduzindo os riscos de possíveis infestações em aves de postura.(AU)

This study aimed to characterize the epidemiology of the presence of hematophagous mites in posture farms in the state of Minas Gerais. Was used a secondary database with information from 402 chicken houses in 42 commercial properties. The variables used to compose the correspondence model were selected through chi-square tests (P≤0.05). A risk index was built to the presence of hematophagous mites considering some risk factors. Additionally, a study of the spatial analysis was done to evaluate the presence of hematophagous mites in Minas Gerais. Was observed the presence of hematophagous mites in 48% of chicken houses, the presence of O. sylviarum was 45.5%, O. bursa 17.4% and D. gallinae 2.7%. There was an association between the risk index with the intervals for the removal of manure and the presence or absence of synanthropic birds. It was verified that more technified farms do not use acaricide in their chicken houses. The presence of hematophagous mites was observed in the Messoregions South/Southwest of Minas Gerais and between the West and Metropolitan Mesoregion of Belo Horizonte. These results provide knowledge about the epidemiology of these ectoparasites and may contribute to decision making by reducing the risks of possible infestations in poultry.(AU)

Análise epidemiológica dos atendimentos da profilaxia antirrábica humana associados a acidentes com gatos / Epidemiological analysis of human anti-rabies prophylaxis associated with accidents with cats

Objetivou-se conhecer o perfil epidemiológico do paciente que buscou atendimento antirrábico pós-exposição associado a acidentes com gatos domésticos, em Belo Horizonte/MG, no período de 2007 a 2016. Realizou-se uma análise exploratória das fichas de notificação do atendimento antirrábico humano do Sistema de Informação de Agravos de Notificações (Sinan). Nos resultados, observou-se que 37,4% das pessoas eram adultas do gênero feminino, com idade entre 20 e 59 anos, 88,7% residentes em área urbana, 26,1% de etnia branca e apenas 31,7% dos pacientes buscaram atendimento antirrábico com até 24 horas da exposição ao vírus rábico. Lesões por mordedura ocorreram em 75,6% dos casos notificados. Quanto às características dos ferimentos, 59,6% foram superficiais, 62,2% ocorreram em mãos/pés e 50,1% foram lesões únicas. Na faixa etária de zero a 10 anos, as regiões anatômicas mãos/pés e cabeça/pescoço/face totalizaram 58,35%. Ressalta-se a necessidade de adoção de ações socioeducativas junto à população, devido ao risco de transmissão de raiva pelo gato, principalmente em áreas em que o vírus rábico circula em populações de morcegos. Sugerem-se melhorias no preenchimento das fichas de notificação do Sinan para melhor compreender o perfil epidemiológico dos pacientes que buscam o atendimento antirrábico e, assim, tornar mais eficaz a gestão desse serviço público.(AU)

The objective of this study was to know the epidemiological profile of the patient who sought post-exposure anti-rabies treatment associated with accidents with domestic cats in Belo Horizonte, Minas Gerais Brazil, from 2007 to 2016. An exploratory analysis of the reports on human rabies of the Notification of Injury Information System was performed. In the results, it was observed that 37.4% of the individuals were female adults aged 20-59 years, 88.7% were urban residents, 26.1% were white, and only 31.7% sought anti-rabies care within 24 hours of exposure to the rabies virus. Bite lesions occurred in 75.6%. Regarding the type of wound, 59.6% were superficial; as for the anatomical location, 62.2% occurred in hands / feet and 50.1% were single lesions. It is necessary to adopt socio-educational actions among the population, due to the risk of transmission of the rabies by the cat, especially in areas where the rabies virus circulates in bat populations. Improvements in the completion of the SINAN notification sheets are suggested to better understand the epidemiological profile of patients seeking anti-rabies treatment and thus improve the management of this public service.(AU)

Evaluation of antitumor potential of cashew gum extracted from Anacardium occidentale Linn.

This study aims to determine the antitumor potential of cashew gum in vitro and in vivo. The cashew gum (CG) structure is similar to already showed in literature. The cytotoxicity effect of CG was performed by MTT assay, and B16-F10 melanoma model was used to evaluate antitumor effect. The tumor inhibition was calculated based on tumor weight. Hematological, histopathological, FTIR, oxidative stress and Western Blot analysis were performed to elucidate the mechanism of inhibition and toxic effects. As results, CG did not demonstrate cytotoxicity in vitro, however showed a significant tumor inhibition in vivo, with about 36.9 to 43% of reduction in tumor mass, with no toxicity to organs. Animals treated with CG did not show toxicity in normal tissues, FTIR spectrum and oxidative stress analysis of the tumor tissue indicated that CG cause tumor inhibition with the presence of apoptosis morphotype cells, without alterations in the levels of antioxidants components. In addition, it was observed that CG reduced the expression of γH2AX without changing the expression of caspase-3. With this, we can suggest that this polymer can assist in the anticancer activity and/or decrease the side effects of standard drugs used in treatment of cancer.

Biosseguridade para sistemas de produção de peixes em tanque-rede em função da colmatação agravada por Limnoperna fortunei / Biosecurity for fishfarming cage systems due to the highly clogged screen aggravated by Limnoperna fortunei

Este trabalho avaliou a colmatação por Limnoperna fortunei em diferentes materiais para confecção de telas de arame, a dinâmica da colmatação pelo molusco e a relação custo-benefício dos materiais usados em tanques-rede. Utilizaram-se amostras de telas de simples torção de malha 19mm, de cinco tipos diferentes de revestimentos, colocadas na barragem de Salto Caxias, no Rio Iguaçu, estado do Paraná, entre julho de 2012 e julho de 2014. A cada seis meses, foi verificado o ganho de peso das telas em razão da colmatação, além da contagem do número de mexilhões aderidos. Após as coletas dos dados, foi realizado o teste estatístico de Kruskal-Wallis para se avaliar o ganho de peso das telas devido à colmatação. Realizou-se também uma pesquisa com 21 empresas para se obter o preço comercializado de telas para confecção de tanques-rede e se avaliar a expectativa de durabilidade dos materiais. Verificou-se que os diferentes materiais avaliados para as telas influenciam na colmatação e aderência do mexilhão-dourado; além disso, constatou-se que a tela mais eficiente quanto ao custo/ano é a de arame galvanizado plastificado e, para baixa colmatação, a de arame Bezinal.(AU)

This research evaluated degree of clogging by Limnoperna fortunei in different materials for wire mesh fabrication, the dynamics of mollusk sealing and the cost-benefit ratio of these materials used in tank-nets. Samples of single-twist screens of 19 mm mesh were used, from five different types of coatings were placed in the Salto Caxias dam on the Iguaçu River in the Paraná state, between July 2012 and July 2014. Every six months, it was verified the weight gain of the screens due to clogging and counting of the number of mussels adhered. After the data collection was performed Kruskal-Wallis statistical test to evaluate the weight gain of the screens due to clogging. In addition, a survey was carried out with 21 companies to obtain the commercialized price of screens for the production of net tanks and to evaluate the expected durability of the materials. The different materials evaluated for the screens influenced the sealing and adhesion of the golden mussel. In addition, the most cost-per-year screen is that of plastic-coated galvanized wire and for low clogging it is the Bezinal wire.(AU)

Effects of the Dietary Inclusion of Xylanase on the Performance and Jejunum Morphometry of Meat-Type Quails

The objective of this study was to evaluate the effects of the supplementation of two xylanase products to diets with reduced metabolizable energy fed to meat-type quails during the starter phase (1-14 days). A completely randomized experimental design in a 2 x 3 + 1 factorial arrangement two reduced metabolizable energy (ME) diets, inclusion or not of xylanase, and a control diet with no enzyme addition) was applied, totaling seven treatments with five replicates of 45 quails each. At 14 days of age, jejunum segments were collected for morphometry evaluation. No interaction between the studied factors were detected for performance and jejunal morphometry parameters. Body weight, weight gain, feed intake and feed conversion were not influenced by enzyme inclusion. Reduced ME diets (-70 or -140 kcal/kg) did not affect performance, except for feed intake. Xylanase inclusion increased villus height and villus:crypt ratio. Therefore, xylanase supplementation can be effective in corn and soybean meal-based diets, without causing any impairment in the performance of 1- to 14-day-old quails. Xylanases A and B were more efficient when dietary energy level was reduced in 140 kcal ME/kg, and were also shown to effectively improve the jejunal morphometry of starter meat-type quails.

Occurrence and Epidemiology of Fannia Spp. (Diptera: Fanniidae) in Laying Poultry Farms in State of Minas Gerais, Brazil

Aspects related to epidemiology of flies belonging to Fannia genus were studied in order to determine predisposing factors for its occurrence in layer hens houses of commercial farms in the state of Minas Gerais, Brazil. An observational, analytical and sectional survey was conducted to verify major epidemiological aspects associated to infestations. This research was accomplished starting from an adapted secondary database of and structured with information on the presence and absence of ectoparasites and arthropods, characteristics of chicken houses, the poultry, type of facilities, geographical location and the management. The study was conducted in four hundred and thirty one houses located in forty three farms visited in 2012 year in the state of Minas Gerais. Ten farms (23.25%) and sixty eight houses (15,77%) were observed the presence diptera belonging to Fannia genus. The specie Fannia admirabilis was found in four farms (9,30%), Fannia albitarsis in two farms (4,65%) and only in one farm (2.32%) was observed the presence of Fannia canicularis. For three farms 6,98% was no possible to identify the species only Fannia genus. The epidemiological aspects for the occurrence of these flies were investigated using Poisson regression models. Characteristics such as farm, city of farm, presence of Histeridae beetles, type of facility (cage, on the floor with or without bedding) and the existence of mechanical removal of manure were associated with the occurrence of Fannia spp.(AU)

Evaluation of a new method of oral health education in children with cleft lip and palate.

AIM: To evaluate the efficacy of an oral health educational programme in children with cleft lip and palate. METHODS: The sample comprised 38 children with cleft lip and palate: Group 1-dental prophylaxis; Group 2-education and motivation instructions in oral health and plaque control. Children were evaluated during six appointments, at 30-day intervals. The Patient Hygiene Performance (PHP) index was used to assess plaque control. To evaluate the knowledge on oral health a questionnaire was used. Baseline and 6-month PHP scores were compared through Mann-Whitney and Wilcoxon tests. The questionnaire scores were analysed through t test and paired-t test. RESULTS: Baseline PHP indexes between Groups exhibited no statistically significant differences, while the 6-month PHP indices between Groups showed statistically differences (p < 0.001). Group 2 showed statistically significant differences between baseline and 6-month PHP index (p < 0.001). The comparison of Groups questionnaire scores showed no statistically significant differences neither at baseline nor after 6 months. In Group 1, the level of knowledge between baseline and 6-month periods did not show statistically differences, while Group 2 did. CONCLUSIONS: The oral health educational programme improved the plaque control of children with cleft lip and palate.

Avaliação do tratamento antirrábico humano pós-exposição, associado a acidentes com cães / Evaluation the human anti-rabies treatment associated with accidents with dogs

O estudo da profilaxia da raiva humana contribui para orientação quanto ao uso de vacinas e soros antirrábicos, servindo de base para a definição de estratégias de prevenção, controle e avaliação da doença. Objetivou-se avaliar o atendimento antirrábico humano pós-exposição e possíveis incompatibilidades com o protocolo do Ministério da Saúde, em agressões por cães, no município de Belo Horizonte. Analisaram-se as fichas de atendimento antirrábico do SINAN para comparação dos tratamentos prescritos com as Normas de Profilaxia antirrábica do Ministério da Saúde. As características dos atendimentos foram: quanto à exposição, 93,0% decorrentes de mordedura; quanto à localização da agressão, 35,5% ocorreram nos membros inferiores; quanto ao ferimento, 62,0% foram lesões únicas; quanto ao tipo de ferimento, 65,8% foram superficiais; quanto à condição do animal, 85,0% ocorreram por animais sadios; em 83,4% dos casos os animais eram observáveis; quanto ao tratamento, observação e vacina (57,3%). O tratamento foi inadequado em 32,7% das condutas. O número de tratamentos instituídos foi muito elevado, 75,7% dos casos. De todos os atendimentos 21,2% das indicações foram consideradas excessivas e 11,5% insuficientes. O sistema de vigilância apresenta falhas e existe a necessidade de corrigi-las para que as informações referentes à finalização dos casos sejam conclusivas.(AU)

The study of prophylaxis of human rabies contributes to guidance on the use of vaccines and anti-rabies serums, providing the basis for the definition of strategies for prevention, control and evaluation of the disease. This study aimed to evaluate the service to early post-exposure human anti-rabies and possible incompatibilities with the Ministry of Health protocol attacks by dogs in the city of Belo Horizonte. The anti-rabies care records of SINAN were analyzed for comparison of treatments prescribed in the Prophylaxis of Rabies Standards of the Ministry of Health. The characteristics of the calls were about the exposure, 93.0% resulting from biting; the location of the assault, 35.5% occurred in the lower limbs; the injury, only 62.0% were injuries; the type of injury, 65.8% were superficial; the condition of the animal, 85.0% occurred in healthy animals; 83.4% of the cases the animals were observed; as treatment, observation and vaccine (57.3%). The treatment was inadequate in 32.7%. The number of established treatments was very high, 75.7% of cases. In all 21.2% of indications consultations were considered excessive and 11.5% insufficient. The surveillance system is faulty and there is a need to correct them so that the information regarding the completion of cases are conclusive.(AU)

Dental plaque disclosure as an auxiliary method for infants' oral hygiene.

AIM: This was to evaluate the effectiveness of plaque disclosure as an auxiliary method for early childhoods' oral hygiene. METHODS: The study was performed with 20 mothers and their children (aged 6-36 months), members of a preventive programme, which two groups used one of two approaches: conventional oral hygiene/group I (tooth brushing) and plaque disclosure with subsequent oral hygiene/group II (tooth brushing with prior plaque disclosure). Ten mothers started the study in group I and the other 10 in group II, after one month interval they changed to be in the alternate group. Each group consisted of baseline and three additional visits at weekly intervals. The effectiveness of oral hygiene was assessed in a blind fashion by plaque quantity estimation, using the Green Vermilion index for smooth surfaces and the plaque thickness index for occlusal surfaces. Statistical comparisons were performed using repeated measures ANOVA/Fisher's post hoc test and paired t-test (p < 0.05). RESULTS: For smooth and occlusal surfaces at first and second visits, group II recorded significantly lower plaque indices when compared with group I. Additionally, when considering the mean dental plaque index of all visits, group II also presented lower plaque scores than group I. CONCLUSION: Dental plaque disclosure before toothbrushing helps mothers to enhance the effectiveness of early childhood oral hygiene.

Vaccine effectiveness and use of collar impregnated with insecticide for reducing incidence of Leishmania infection in dogs in an endemic region for visceral leishmaniasis, in Brazil.

Although a national programme for control of visceral leishmaniosis (VL) is being run in Brazil, the disease continues to spread. This programme is essentially based on culling infected dogs from endemic regions. Thus, there is an urgent need to develop other control measures against VL to deter its advance. Here, a subunit vaccine, a recombinant vaccine, an insecticide-impregnated collar and the associations between these measures were evaluated for reducing the incidence of Leishmania infection in dogs. This was through a cohort study conducted in an endemic region of Brazil, considering the incidence and time of total exposure over a period of 1 year. The incidence of VL was estimated by means of serological and molecular diagnostic tests, 180 and 360 days after the application of the control measures. The estimates of the effectiveness (EF) were not significant in any cohort. The EF of the subunit vaccine, the recombinant vaccine and the collar were 26.4%, 32.8% and 57.7% and the upper limit of the 95% confidence interval for EF were 63.7%, 67.9% and 82.5%, respectively. In conclusion, under the conditions of this study, none of the immunogens for VL control was sufficiently effective to protect dogs against infection. On the other hand, use of collars impregnated with insecticide seems to constitute a method with better prognosis, corroborating other studies in this field.
