Deslocamento do abomaso à esquerda em bovinos leiteiros: da etiologia ao diagnóstico

A pecuária leiteira vem sofrendo ao longo dos últimos anos, constantes mudanças com o intuito de maximizar a produção. A contínua seleção para uma maior produção de leite em conjunto com o aumento da capacidade digestiva e profundidade corporal aumentou a susceptibilidade de ocorrência de várias enfermidades abomasais, como o deslocamento do abomaso. O deslocamento de abomaso é uma doença economicamente importante na bovinocultura leiteira e é definido como uma síndrome multifatorial onde há basicamente duas possibilidades de deslocamento, na primeira, a víscera pode deslocar-se à esquerda, causando o deslocamento do abomaso à esquerda e a segunda possibilidade, o órgão pode mover-se totalmente para o lado direito, provocando o deslocamento do abomaso à direita, sendo que o primeiro ocorre mais frequentemente. O período de maior ocorrência do deslocamento do abomaso à esquerda, se insere imediatamente ou até seis semanas após o parto. Assim, objetivou-se com essa revisão sistemática, elucidar as principais causas e fatores de risco, os variados sinais clínicos e os diversos métodos diagnósticos dessa enfermidade. Conclui-se que, é de extrema importância conhecer desde a causa, até o diagnóstico do deslocamento do abomaso à esquerda, para que auxilie os médicos veterinários a identificarem o problema na propriedade, direcioná-lo a um tratamento adequado e tomar medidas preventivas, eliminando os fatores de risco e consequentemente diminuindo a incidência do problema.

Reparo periapical de dentes tratados endodonticamente submetidos a movimentação ortodôntica

The relationship of Orthodontics and Endodontics is being clarified with the development of evidence-based dentistry. However, few studies have reported the repair of periapical lesions with orthodontic treatment. Therefore, the aim of this study was to evaluate the available evidence on periapical repair of endodontically treated teeth during orthodontic movement. The strategy used was the electronic search with keywords and criteria including studies published up to July 2011. It was also carried out qualitative assessment of the articles methodology. Although a significant number of studies have reported this topic, only two filled the criteria for inclusion in this systematic review. The results obtained in the literature suggest that orthodontic treatment should be interrupted to perform endodontic treatment. During this therapy, the use of root canal dressing based on calcium hydroxide for at least 14 days, and sealer with adequate biological property are indicated. After this phase, orthodontic movement of the endodontically treated teeth can be resumed without waiting period.

Doença periodontal em pacientes com Diabetes Mellitus: influência de polimorfismos genéticos?

Currently it is clear that there are several factors that can act as modifiers of diseases, without causing them directly, but having the potential to make these conditions to progress faster and more severe. There is a growing number of studies investigating the relationship between Diabetes Mellitus (DM) and Periodontal Disease (PD), including some studies focusing on the influence of genetic factors in this process. The aim of this study was to verify through a literature review, the influence of genetic polymorphisms in the development of PD in patients with DM. PubMed and BIREME were used as databases and the terms Periodontitis or Periodontal Disease, Polymorphism, Diabetes Mellitus were searched. After a refinement in the literature, five studies were selected and they were related to chronic PD with DM and polymorphisms in cytokine genes, especially interleukin 1 (IL1) e IL6. Polymorphisms were associated with a higher concentration of pro-inflammatory cytokines in the gingival crevicular fluid of diabetic patients when compared to non-diabetic. In conclusion, it is necessary to confirm this association with longitudinal studies that must investigate a larger number of cytokine genes in order to understand the cause-effect relationship between genetic polymorphisms, DM and PD.

Guia prático de medicina baseada em evidências

Neste livro são expostos, para uso de profissionais da área, os princípios básicos e conceitos fundamentais, além dos procedimentos necessários para a prática da Medicina Baseada em Evidências (MBE). A MBE é uma prática relativamente nova, criada em 1992, pelo cientista epidemiologista Gordon Guyatt, na canadense McMaster University. Trata-se da utilização e do desenvolvimento de métodos rigorosos que respondam a questões clinicas sobre efetividade, eficiência e segurança de determinado tratamento e prevenção, bem como sobre a sensibilidade e especificidade de testes diagnósticos de certa doença na área de saúde. A MBE propõe realizar pesquisas de boa qualidade metodológica e livres de vieses e conflitos de interesse, de forma que as respostas sejam adequadas para auxiliar na tomada de decisão clínica. Segundo a MBE, a melhor forma de saber se uma medicação específica é eficaz no tratamento de determinada doença é a revisão sistemática de ensaios clínicos randomizados, que mapeiam os estudos publicados e não publicados realizados mundialmente sobre o assunto. Tal revisão deve ainda contar com metodologia rigorosa que busque, por exemplo, explicar resultados contraditórios sobre a mesma questão e comparar estudos com diferentes amostras para detectar possível diferença estatística. De forma didática e detalhada, mas mantendo todo o rigor científico, esta obra tem caráter de manual. Ao longo dos capítulos, seus autores explicam conceitos e apresentam o passo a passo da utilização da MBE para os profissionais de saúde.

Causes for the underreporting of adverse drug events by health professionals: a systematic review

Objective: Identifying the main causes for underreporting of Adverse Drug Reaction (ADR) by health professionals. Method: A systematic review carried out in the following databases: LILACS, PAHO, SciELO, EMBASE and PubMed in the period between 1992 and 2012. Descriptors were used in the search for articles, and the identified causes of underreporting were analyzed according to the classification of Inman. Results: In total, were identified 149 articles, among which 29 were selected. Most studies were carried out in hospitals (24/29) for physicians (22/29), and pharmacists (10/29). The main causes related to underreporting were ignorance (24/29), insecurity (24/29) and indifference (23/29). Conclusion: The data show the eighth sin in underreporting, which is the lack of training in pharmacovigilance. Therefore, continuing education can increase adherence of professionals to the service and improve knowledge and communication of risks due to drug use.

Intervenções com a atividade física em crianças e adolescentes com deficiência intelectual: uma meta-análise

Abstract Intellectual disability is development atypical conditions that involve issues on a number of factors, such as intellectual skills, adaptive behavior, interactions and social roles. Furthermore, they report higher rates of physical inactivity than the general population, as well as participating less and less of regular physical activity, as they grow and age. The participation of people with intellectual disabilities in physical activity programs promotes, benefits of prevention of diseases, particularly cardiovascular, improvement of intellectual and cognitive ability in addition, regular physical activity promotes reduction of body fat. Therefore the aim of this study was to identify through a systematic review, physical activity programs for adults with intellectual disabilities and their extension of the benefits, limitations and recommendations, moreover, the following objectives: to analyze the types of physical activity programs and determine which is the most suitable for adults with intellectual disabilities, and to determine the benefits that physical exercises programs entail for adults with intellectual disabilities. The initial electronic search resulted in 2808 manuscripts. The predetermined exclusion criteria were: review process of the studies involved reading titles, abstracts and full texts checking. After all these phases, eight manuscripts met the inclusion criteria of the review. Articles presented participants aged between 18 and 67 years with mild to moderate intellectual disability. The intervention period was from 2.5 months studies ranged up to 9 months and the weekly frequency was from one to three times a week. The intervention types differ between the articles analyzed, including leisure and recreation activities, combined exercises of strength and muscular endurance, aerobic activities of hiking, with races and exercise bikes, widespread activities and sports specialization, athletics and...

Speech-language therapy for treatment of dysphagia and dysphonia in systemic granulomatous diseases: granulomatous diseases: dysphagia and dysphonia treatments

The granulomatous lesions are frequently founded in infectious diseases and can involve the larynx and pharynx and can cause varying degrees of dysphonia and dysphagia. There is still no systematic review that analyzes effectiveness of speech therapy in systemic granulomatous diseases. Research strategy: A systematic review was performed according to Cochrane guideline considering the inclusion of RCTs and quasi-RCTs about the effectiveness of speech-language therapy to treat dysphagia and dysphonia symptoms in systemic granulomatous diseases of the larynx and pharynx. Selection criteria: The outcome planned to be measured in this review were: swallowing impairment, frequency of chest infections and voice and swallowing symptoms. Data analysis: We identified 1,140 citations from all electronic databases. After an initial shift we only selected 9 titles to be retrieved in full-text. After full reading, there was no RCT found in this review and therefore, we only described the existing 2 case series studies. Results: There were no randomized controlled trials found in the literature. Therefore, two studies were selected to be included only for narratively analysis as they were case series. Conclusion: There is no evidence from high quality studies about the effectiveness of speech-language therapy in patients with granulomatous diseases of the larynx and pharynx. The investigators could rely in the outcomes suggested in this review to design their own clinical trials.

Sintomas auditivos e desordens temporomandibulares

Introduction: A variety of hypotheses have been proposed to explain the association between temporomandibular disorders and hearing symptoms, including the many anatomical and/or neurological ways, as of a muscle or joint dysfunction, can cause such symptoms. Objective: The purpose of this study is to discuss, through a systematic review of literature, the interrelation between hearing symptoms and temporomandibular disorders. Material and Methods: We consulted the Medline/PubMed, ISI and Scielo in the period 1918 to 2008. The terms related to the research were: “temporomandibular disorders”, “signs and symptoms of temporomandibular disorders”, “otologic symptoms” and “aural symptoms”, where 19 papers were included using the pre-selected criteria for the manufacture of a meta-analysis. Results: According to the findings, the hearing symptoms most often associated with temporomandibular disorders were otalgia and tinnitus, followed by vertigo and hearing loss, respectively. Conclusions: It’s clear the correlation between hearing symptoms and temporomandibular disorders, however there is a need clinical and scientific research more complex to prove the specific cause-effect relationships between them.

Odontologia baseada em evidências: otimizando a prática e a pesquisa

Clinical decisions in dentistry are often based on the knowledge obtained during graduation, clinical experience, information shared with colleagues and professor, textbooks, seminars, conferences and continuing education courses. However, it is necessary to know if this information is derived from scientifically validated researches since too much information may complicate this process. Initially in medicine and later in other health areas a method which enables a critical evaluation of scientific papers related to a specific issue and also, whenever it is possible, an evaluation of the results by meta-analysis,was developed by Cochrane in order to reduce the bias towards all information obtained. The aim of this work is to present some aspects of the Evidence Based Dentistry (EBD) and to show how this methodology can be used to better substantiate scientifically the clinical decision of the dentist and improve researches design with scientific validity. The paper discusses editorial trends focused on the EBD, shows the differences between a systematic and a conventional review, describes data about Cochrane and the advantages of scientific evidence synthesis and the implications of EBD for clinical practice and research as well as recommendation grades and evidence levels of general scientific studies.
