Objective: To conduct a survey on national databases about Oral Health Program (OHP) publications in schools, in the last eleven years. Material and Methods: A survey was conducted in two main bases of national publications in the field of dentistry: Bireme and Scielo. To start the research, it was used the articles theme/subject. In the search, it was used the keywords 'oral health education', 'programs and oral health and dentistry', 'programs and oral health and education'. Results: A total of 20 publications were selected. From these, seven (35%) had the aim to evaluate educational methods used in OHP, 12 (60%) evaluated the effectiveness of the OHP itself developed in the school and one (5%) reported the experience of OHP. Only two publications did not get positive results and the other eighteen obtained advantageous results. Conclusion: In the national scientific literature, there are few publications about the subject in question, suggesting that the successful experiences about OHP in schools must be published to be replicated in other parts of Brazil.

Allogeneic, fresh-frozen bone has been used in order to replace bone autografts. However, its osteoinduction and osteoconduction properties are not well-defined in the scientific literature. This work aimed to evaluate samples of homogenous bone grafts in humans by qualitative histological and immunohistochemical analysis. For this, ten pre-selected patients underwent surgical augmentation of bone defects. The homogenous fresh frozen block bone graft was stabilized and fixed by bicortical screws. After six months, the reopening procedure was performed for installation of osseointegrated implants. At this time surgical bone graft samples were removed by means of drill trephine. The samples were fixed in 10% formalin, processed with decalcified paraffin, and stained with hematoxylin and eosin. Immunohistochemistry was performed for the expression of Caspase 3 enzyme. The slides were brought to light microscopy for qualitative histology and immunohistochemistry. The results showed non-vital bone tissue, with few areas of deposition of new bone formation on the amorphous matrix, presence of chronic inflammatory infiltrate with areas of osteomyelitis, and expressive immunolabeling of Caspase 3. Given the methods employed and the results it was concluded that the allograft fresh-frozen block is not incorporated into the recipient bed after a healing period of six months.

Over the past four decades it occurred a great expansion of science education research in Brazil (TEIXEIRA, 2008). Considering the scientific production in the area, descriptive studies, called state of the art are necessary, but little found in Brazilian scientific literature, especially in the field of science education. In this context, this paper identifies and describes the main features and trends of Brazilian research in the field of education in science museums, released in the form of dissertations and thesis, in the period 1970 to 2010. It is a qualitative and quantitative research, which performs a document analysis, in a bibliographical review. We mapped 153 academic researches, mainly in the Rio-São Paulo axis, mostly in the last decade, showing that the area can be characterized as an emerging field in science education.

Studies have shown that encopresis, related to bowel control disorder, can bring significant impact for the individual life, such as low self-esteem and deficits in social interaction. Despite the significant impairment recognized that this disorder can have on child development, the scientific literature has given little attention to the theme, with a low number of publications on the subject. Thus, this paper investigated Brazilian publications in psychology related to encopresis between 1994 and 2013 in data base Lilacs and Scielo. 231 articles were found and were selected those that reported only intervention in encopresis. There were five articles and four published by the same journal and described behavioral interventions, and one author wrote three. The other one was psychoanalytic. The surveys were conducted with children and adolescents and behavioral interventions have been successful with remission of encopresis symptoms. The data affirm the deficiency in publications in the area and possibly limited number of psychologists investigating the issue, which is of significant importance.

This study aimed at investigating, in the national and international scientific literature, how aromatherapy is used as a therapeutic tool to reduce anxiety. It is a bibliographic study that adopted integrative literature review as a method. Studies published on databases Scielo, Medline and Cinahl from 2008 to 2012 were selected. A sample of 20 scientific articles was analyzed, and of these, 13 had an experimental and a quasi--experimental design whereas 07 were systematic or integrative reviews. The synthesis of knowledge sho-wed that aromatherapy represents a safe therapeutic practice although it is still underestimated in health care practices. The construction of evidence levels was not possible due to discrepancies in the studied populations, in research designs, the various essential oils used and the different methods for aromatherapy application. The knowledge gaps identified in these studies are related to the need to develop new forms to evaluate the effectiveness of this practice, including the therapist-patient relationship and the different communication forms that are intrinsic to aromatherapy.

Objective: Review of scientific literature on the history of tuberculosis (TB), the natural history of TB in humans, extrapulmonary TB in urogenital form, including epidemiology, diagnosis and treatment. Method: Literature review using PubMed databases, BIREME, SciELO, LILACS and Google Scholar, as well as books, manuals and official documents of Ministério da Saúde (MS) and World Health Organization (WHO). Results: Focused as discussion topics, history, diagnosis and treatment of urogenital tuberculosis and reflection on the diagnostic challenge to be faced by health professionals. Conclusion: The diagnosis of urogenital tuberculosis is difficult and often delayed and may lead to important consequences. Faced with a patient with chronic urinary symptoms or infertility tuberculosis should always be investigated.
