Determinação da idade dental de crianças brasileiras nordestinas: novos valores de conversão de maturidade dental para população específica

Since Demirjian's system of estimating dental maturity was first described, many researchers from different countries have tested its accuracy among diverse populations. Some of these studies have pointed out a need to determine population-specific standards. In Brazil, the Northeast region is the one that most suffers the negative impact of exodus, specially related to the increase of abandoned children in the cities. The aim of this study was to test the accuracy of Demirjian's system for assessing the dental maturity of northeastern Brazilian children, so as to present a scale for maturity score conversion into dental age developed specifically for this population. This could be used for forensic, anthropological and legal matters, and also as a model for other countries attempting to formulate their own conversion scales. Panoramic radiographs of 1,491 children (821 females and 670 males), aged 7 to 13 years, from Ceará state, northeast Brazil, were assessed by a single observer to determine dental age (DA) according to Demirjian's system. The mean percentage of intra-observer agreement was 86.6%, with a mean Cohen's Kappa coefficient of 0.67 (substantial agreement). The DA was compared by paired t-test to subjects' chronological age (CA). The differences between CA and DA in all age groups were statistically significant (p<0.0001), demonstrating a great advancement in DA among Brazilians. Scatter plots were drawn for both genders, and the data were fitted to a growth curve, y = 100/ (1 + e-a(x b)). Graphs corresponding to the 50th percentile curves were produced. A table with new values for the conversion of maturity score into dental age for northeastern Brazilian children is presented. The great advancement in DA, as obtained by Demirjian's system in this population, justified the determination of specific scores for dental maturity assessment

Efetividade da terapia fisica descongestiva na cicatrização de úlceras venosas

A venous ulcer is the most serious clinical manifestation of chronic venous failure, and the most frequent in lower limbs, accounting for 70% of all ulcers. Patients may suffer from this infirmity for several years without healing of the lesion if treatment is inadequate. The aim of this investigation was to verify the effectiveness of decongestive physical therapy in the healing of venous ulcers. This is a quasi-experimental, interventionist study, with paired, non-probabilistic sampling, composed of 50 patients divided into two groups: control and intervention, each composed of 25 patients. Both groups were identically treated for six months with daily dressings and the latter also underwent complex physical therapy consisting of a combination of the following techniques: manual lymphatic drainage, compression bandaging, lower limb elevation, myolymphokinetic exercises and skin care. The study was approved (Protocol no. 59/2007) by the Ethics Committee of the State University of Southeast Bahia. The Mann-Whitney and Chi-square tests were applied for data analysis. After statistical analysis the patients who underwent therapy showed a statistically significant difference with respect to wound contraction starting in the second month of treatment. Compared to the control, the intervention group showed a greater reduction in both pain and edema starting in the third and fourth month of therapy, respectively. To reinforce these findings, the mean percentage of tissue present at the base of the ulcer (granulation/fibrin ratio) was calculated. The intervention group showed greater granulation at the base of the ulcer compared to the control, significant from the second month of treatment on. It was observed in this study that lymphotherapy, when compared between the intervention and control groups, accelerated the healing process, and reduced pain and edema in the affected limbs. It is expected, therefore, that these results widen scientific knowledge and we suggest that this therapy be used 78 not only to reduce lymphedema, but also as a treatment option for venous ulcers, given its easy application and low cost. The data, therefore, demonstrated the importance of basic care on the part of a multiprofessional and transdisciplinary health team involved in the healing process of these infirmities, thereby contributing to better quality of life in these individuals

Alterações radiográficas e ultra-sonográficas iniciais em osteoartrite experimental eqüina

Avaliaram-se oito articulações metacarpofalangeanas (MCF) de eqüinos adultos pelos exames radiográfico e ultra-sonográfico após indução cirúrgica de uma instabilidade articular, para mimetizar as alterações iniciais da osteoartrite (OA) naturalmente adquirida. Foram mensurados a circunferência articular, a amplitude do movimento articular e o grau de claudicação dos membros torácicos (avaliação clínica). Dez dias após a intervenção cirúrgica os animais foram exercitados em um andador por um período de 60 dias. Os exames radiográfico e ultra-sonográfico foram realizados antes da intervenção cirúrgica e após 25, 40 e 70 dias, e a avaliação clínica, semanalmente, durante todo o período experimental. Observaram-se alterações ultra-sonográficas aos 25 dias após a instabilidade articular, enquanto as alterações radiográficas somente foram visualizadas aos 40 dias. Houve aumento significativo (P<0,05) da circunferência articular da articulação MCF operada (25,75cm± 1,1) a partir do sétimo dia, em relação à articulação controle (24,88cm± 1,0) e diminuição da amplitude do movimento da articulação operada (96,38º± 10,7) a partir do 25º dia, em relação ao seu valor basal (109,24º± 10,3) e em relação ao controle (108,75º± 8,3). O grau de claudicação aumentou significativamente (P<0,05) durante o período do estudo, com valor médio do escore de 1,5 para o membro operado em relação ao membro contralateral. em conclusão, os sinais iniciais da OA cirurgicamente induzida foram melhor e mais precocemente detectados pela ultra-sonografia quando comparado ao exame radiografico. As mensurações da circunferência articular e da amplitude do movimento articular são úteis na avaliação das doenças articulares.

As coisas estão no (meu) mundo, só que eu preciso aprender. Autobiografia, reflexividade e formação em Educação Nutricional

This paper gives clues for the educative action in nutrition subjects. It deals about the professors experiences deployments lived in 2003 e 2004, both in Nutrition undergraduate course of the Federal University of the Rio Grande do Norte (UFRN), in Nutrition Education and Supervised Internship in Social Nutrition academic disciplines, as well as in the II Update Course in Nutrition Practices for Health Basic Care , offered to the supervisors nutritionists of internship, in this same department, being able to be characterized as an action-research, with interventionism purpose. The study stands out the importance of a new point of view about the nutritionist formation to overcome the limits imposed by the scientism, and the adoption of a complex and reflexive reference about the educational practice in this area. The corpus is made up by 81 undergraduate students alimentary autobiography (source of generating subjects for interventions with the nutritionists), 17 questionnaires and 05 interviews, being 03 of them biography (the start up for an initial dialogue with the nutritionists). The data found and the professors experiences allied to a theoretic reference, by the light of the education proposals for the XXI century were used as establishment elements for the proposition of five guidance axles used to build a complex and reflexive nutrition education, which are: 1) Take the cookery and the culture of eating together as significant elements for the human being integral formation; 2) Conceive the religion manifestations associated to feeding process as relevant elements of the human food culture; 3) Discuss the rupture nature/culture aiming the preservation of live in earth; 4) Search for the overcoming of the identity conflicts by a higher inclosing conscience degrees of being part of this process. 5) Face the limits of fragmented formation. The presented thesis stands that the autobiography method, allied to the freirean pedagogy and to a complex reference, could be taken as an important tool to the health educative subjects, contributing to the formation of reflective individuals able to transform themselves and the world.

A expansão da agroindústria do mel no Rio Grande do Norte

The beekeeping activity has become in all regions of Brazil until the early 80s and from 2000 to beekeeping Northeast also has developed, becoming a major oil producing honey. The Rio Grande do Norte following these developments happened to occupy fourth place in the ranking of export of honey between the states of the Northeast in 2007. Therefore, the aim of this paper is to present a macro radiography of recent developments in the production chain of honey in the state of Rio Grande do Norte, organizing and discussing the information, collected in the period 2004 to 2007, as well as evaluating the prospect of the honey industry in order to provide a diagnosis able to identify opportunities and enhance the marketing of their products. From the methodological point of view, this study can be classified as a research study exploratory and descriptive by using questionnaires. The group of several studies has been productivity, production and market. Search results indicated the growth of industry in 4 years of activity by the number of beehives full and populated, infrastructure, production and marketing of the state. It can be said that beekeeping of Rio Grande do Norte, despite its potential for developing the activity comes in a different way when compared to other activities, because the actors who play to start the activity through training and to play with it in a professional manner, in addition to support staff who work in the industry

Fisioterapia respiratória em crianças com pneumonia: revisão sistemática

Introduction: Pneumonia is an inflammatory lung disease and it is the greatest cause of deaths in children younger than five years of age worldwide. Chest physiotherapy is widely used in the treatment of pneumonia because it can help to eliminate inflammatory exudates and tracheobronchial secretions, remove airway obstructions, reduce airway resistance, enhance gas exchange and reduce the work of breathing. Thus, chest physiotherapy may contribute to patient recovery as an adjuvant treatment even though its indication remains controversial. Objectives: To assess the effectiveness of chest physiotherapy in relation to time until clinical resolution in children (from birth up to 18 years old) of either gender with any type of pneumonia. Methods: We searched CENTRAL 2013, Issue 4; MEDLINE (1946 to May week 4, 2013); EMBASE (1974 to May 2013); CINAHL (1981 to May 2013); LILACS (1982 to May 2013); Web of Science (1950 to May 2013); and PEDro (1950 to May 2013). We consulted the ClinicalTrials.gov and the WHO ICTRP registers to identify planned, ongoing and unpublished trials. We consulted the reference lists of relevant articles found by the electronic searches for additional studies. We included randomised controlled trials (RCTs) that compared chest physiotherapy of any type with no chest physiotherapy in children with pneumonia. Two review authors independently selected the studies to be included in the review, assessed trial quality and extracted data. Results: Three RCTs involving 255 inpatient children are included in the review. They addressed conventional chest physiotherapy, positive expiratory pressure and continuous positive airway pressure. The following outcomes were measured: duration of hospital stay, time to clinical resolution (observing the following parameters: fever, chest indrawing, nasal flaring, tachypnoea and peripheral oxygen saturation levels), change in adventitious sounds, change in chest X-ray and duration of cough in days. Two of the included studies found a significant improvement in respiratory rate and oxygen saturation whereas the other included study failed to show that standardised respiratory physiotherapy and positive expiratory pressure decrease the time to clinical resolution and the duration of hospital stay. No adverse effects related to the interventions were xvi described. Due to the different characteristics of the trials, such as the duration of treatment, levels of severity, types of pneumonia and the techniques used in children with pneumonia, as well as differences in their statistical presentation, we were not able to pool data. Two included studies had an overall low risk of bias whereas one included study had an overall unclear risk of bias. Conclusion: Our review does not provide conclusive evidence to justify the use of chest physiotherapy in children with pneumonia due to a lack of data. The number of included studies is small and they differed in their statistical presentation

Avaliação e monitoramento de políticas públicas: criação de um modelo sistêmico aplicado ao Instituto de Assistência Técnica e Extensão Rural do Rio Grande do Norte (EMATER-RN)

The nature of this thesis is interventionist and aims to create an alternative on how to control and evaluate the public policies implementation developed at the Institute for Technical Assistance and Rural Extension of Rio Grande do Norte State. The cenarium takes place in a public institution , classified as a municipality that belongs to the Rio Grande do Norte government and adopts the design science research methodology , where it generates a set of artifacts that guide the development of a computerized information system .

Engenharia nos sertões nordestinos: o Gargalheiras, a Barragem Marechal Dutra e a comunidade de Acari, 1909-1958

In Brazil, between the late nineteenth and early decades of the twentieth, polytechnic engineers assumed an important role in discussing the establishment of a modern country. The problem of drought in northeastern Brazil gave the professionals performance, within an interventional process more mounts, the conception plans and measures for the purposeful integration of the territory afflicted. With the foundation of Inspetoria de Obras Contra as Secas (IOCS), in 1909, the actions to combat drought and would be institutionalized, them, studies performed out by technical and scientific committees would be systematically applied in the Brazilian Northeast. So, This work was central objective understand the historical process inplantation of a whole infrastructure of modern character by professional technical and their consequences within the Northeast Geographic space, in specific, in the municipality of Acari in the State of Rio Grande do Norte, in the first half of the twentieth century. The politics of the government, through technical education and scientific engineers polytechnics, would emphasize, during the twentieth century, the building of dams, and irrigation canals, wells, railways, highways, between other elements, that would soon transform the physical space-northeast, specifically, the territory acariense. These works began to contribute to the setting of man backcountry their land, promote the regular practice of agriculture even in periods of drought and, the integration, especially, economic of territory acariense the other producing regions of Rio Grande do Norte and the Northeast as well as promoting the modification of the landscape of the world backcountry. These actions functioned as elements of modernity and progress that transformed the space by favoring by favoring the formation of urban networks (urban) in this space

Avaliação clínica e radiográfica das complicações técnicas em próteses sobre implantes

The evaluation criteria of the cases treated with dental implants are based on clinical and radiographic tests. In this context it is important to conduct research to determine prognosis of different types of prosthetic rehabilitation and determination of the main problems affecting this type of treatment. Thus, the objective of this study was to assess the prosthetic conditions of individuals rehabilitated with implant-supported prosthesis. In this cross-sectional study 153 patients were treated, accounting for a sample of 509 implants. The failures were observed by clinical and radiographic examination. The results showed that the fracture (0.2%) loss (0.4%) and loosening of the screws (3.3%) were failures are less frequent. The fracture structures as the resin (12.4%), porcelain (5.5%) and metallic (1.5%), loss of resin that covers the screw (23.8%) and loss of retention overdentures on implants (18.6%) had a higher occurrence. The failure of adaptation between the abutment and the implant (6.9%) and especially between the prosthesis and the abutment (25.4%) had a high prevalence and, when related to other parameters showed a significant association, particularly with the cemented prosthesis (OR = 6.79). It can be concluded that to minimize the appearance of failures, protocols must be observed from diagnosis to the settlement and control of prostheses on implants, particularly with respect to technical steps of the making of the prosthesis and care in radiographic evaluating the fit between their components

Tratamento da doença arterial coronariana em renais crônicos em diálise do Hospital das Clínicas da Faculdade de Medicina de Botucatu - UNESP

FUNDAMENTO: O tratamento intervencionista da insuficiência coronariana é subempregado nos pacientes em diálise, pois há poucos estudos comprovando sua eficácia. OBJETIVO: Avaliar os resultados do tratamento intervencionista da doença arterial coronariana em pacientes tratados por diálise no HC da FMB. MÉTODOS: Foram avaliados 34 pacientes em diálise submetidos à angiografia coronariana entre set/95 e out/04, divididos de acordo com a presença ou ausência de lesão coronariana, tipo de tratamento e presença ou ausência de diabetes. Os grupos foram comparados de acordo com suas características clínicas e sobrevida. A sobrevida dos pacientes submetidos a tratamento intervencionista foi comparada à sobrevida geral dos 146 pacientes em diálise na instituição no mesmo período. O tratamento intervencionista foi indicado nas mesmas situações clínicas que na população geral. RESULTADOS: Os 13 pacientes que realizaram coronariografia e não exibiam lesões coronarianas apresentaram sobrevida de 100% em 48 meses, contra 35% dos 21 coronarianos no mesmo período. Os diabéticos coronarianos apresentaram sobrevida inferior aos não-diabéticos. A angioplastia exibiu pior prognóstico quando comparada à cirurgia; entretanto 80% dos submetidos a angioplastia eram diabéticos. Os 17 pacientes submetidos a procedimentos de revascularização coronariana apresentaram sobrevida semelhante aos 146 pacientes gerais do serviço. CONCLUSÃO: Esta pequena casuística mostra que a revascularização miocárdica, quando indicada, pode ser realizada em pacientes em diálise. Esta conclusão é corroborada pelo índice de mortalidade semelhante nos dois extratos de pacientes: coronarianos revascularizados e pacientes em diálise de maneira geral.

Aspectos metodológicos relacionados aos sistemas manométricos utilizados em estudos hemodinâmicos

Atualmente, diante das técnicas atuais, a manometria tem sido relegada a plano secundário durante a cateterização cardíaca. No entanto, ainda fornece importantes informações para identificação e avaliação das doenças cardiovasculares. Os dados coletados durante os exames possibilitam a obtenção de variáveis quantitativas e qualitativas, as quais podem ser comparadas aos padrões normais. Os sistemas manométricos são compostos por transdutor, amplificador e registrador, que, em conjunto, devem espelhar com fidelidade a morfologia e os valores das variáveis analisadas. Para atingir esse objetivo, é necessário desempenho adequado de todos os componentes. Se uma determinada informação é de extrema relevância, o operador deve gastar tempo suficiente para obtê-la de maneira inequívoca. Assim, o operador deve estar familiarizado com os sistemas manométricos e com as fontes de erro relacionadas com as técnicas de registro, cateteres, conectores e fluidos. Com os fundamentos analisados neste manuscrito, salientamos que deve ser dispensada atenção às ondas de pressão usadas nas interpretações da fisiopatologia das doenças cardiovasculares.

Análises clínicas, radiográfica e microscópica de molares permanentes sem ou com lesão de cárie na superfície oclusal

O presente trabalho, objetivou avaliar comparativamente o diagnóstico clínico, radiógráfico e histológico de molares permanentes humanos sem ou com lesão de cárie na superfície oclusa!. Vinte e quatro dentes que estavam armazenados em formalina a 10% foram selecionados e em seguida submetidos a um exame clínico, através da inspeção visual, onde foram separados em 3 grupos: grupo 1 (G1), formado por dentes hígidos; grupo 2(G2), por dentes com pigmento na superfície oclusal e grupo 3(G3), aqueles com lesão de cárie na oclusal. Este exame foi realizado com auxílio de luz artificial proveniente de um refletor odontológico, sem qualquer manipulação da superfície. Para cada dente foram realizados duas tomadas radiográficas com e sem tela milimetrada, no sentido vestibulo lingual por um dos avaliadores, simulando uma radiografia interproximal, onde o feixe incidiu perpendicular ao longo eixo do dente. Em seguida os dentes foram preparados histomorfologicamente para coloração com hematoxilina e eosina e análise microscópica. Pela avaliação dos resultados a partir da amostra de 100%, foi possível concluir: 1) Os dentes clinicamente considerados hígidos (G1) apresentaram radiograficamente 74,99% de ausência de imagem radiolúcida e em 25% presença desta imagem na Junção Amelo¬dentinária e microscopicamente ausência de cárie em 100%; 2) os dentes que clinicamente apresentaram fissura pigmentada' (G2) notou-se em 33,33%, ausência da imagem radiolúcida e em 66,66% presente esta imagem na junção amelodentinária, 100% de ausência de cárie através da análise microscópica; 3) clinicamente, os dentes que apresentaram lesão de cárie (G3), radiograficamente foram comprovados 100% de imagem radiolúcida sugestiva de cárie e microscopicamente dos 100% destas, foram considerados cáries rasa (16,66%), média (61,10%) e profunda (22,22%) respectivamente
