A 2-year clinical evaluation of fluoride-containing pit and fissure sealants placed with an invasive technique

The aim of this study was to clinically evaluate fluoride-containing sealants in teeth subjected to minimal enamel reduction (preventive resin restorations). Two hundred fourteen sealants (109 Fluro Shield and 105 Delton Fluor) were applied in 153 teeth of 32 subjects. The sealants were evaluated for superficial irregularities, marginal adaptation, retention, and caries after 6, 12, 18, and 24 months. After 6, 12, and 18 months, the attendance at recall was 100.00%. After 24 months, 93.75% of subjects returned for reevaluation. Although total or partial loss of sealant occurred in a few instances, no occlusal caries was found in any tooth at any recall. No statistically significant differences in the results of the clinical evaluation were found between sealant in the maxillary and mandibular dentitions.

Escalated aggressive behaviour and facultative parental care in the nest building gladiator frog, Hyla faber

Agonistic encounters and facultative parental care in Hyla faber were observed in two localities in southeastern Brazil. Maximum male density was 0.9 and 3.3 males/m2 in Campinas and Ribeirão Branco, respectively. Aggression was escalated and the highly variable aggressive calls were specific to each phase of the encounter. The last, more aggressive phases rarely occurred in Campinas; in Ribeirão Branco they occurred frequently. Male parental care (egg attendance) was common in Ribeirão Branco while it was never observed in Campinas. Egg attendance lasted one to two nights and was observed only during high male density. The main benefit of egg attendance seemed to be avoiding nest intrusion by other males (sunken eggs and/or embryos invariably die). Males may build additional nests during egg attendance, but attending males did not attract females (they did not call).

Size and lipid content of nonmyrmecochorous diaspores: Effects on the interaction with litter-foraging ants in the Atlantic rain forest of Brazil

Ants are often attracted to diaspores not adapted for dispersal by ants. These diaspores may occasionally benefit from this interaction. We selected six nonmyrmecochorous plant species (Virola oleifera, Eugenia stictosepala, Cabralea canjerana, Citharexylum myrianthum, Alchornea glandulosa and Hyeronima alchorneoides) whose diaspores differ in size and lipid content, and investigated how these features affect the outcome of ant-diaspore interactions on the floor of a lowland Atlantic forest of Southeast Brazil. A total of 23 ant species were seen interacting with diaspores on the forest floor. Ants were generally rapid at discovering and cleaning the diaspore pulp or aril. Recruitment rate and ant attendance were higher for lipid-rich diaspores than for lipid-poor ones. Removal rate and displacement distance were higher for small diaspores. The large ponerine ant Pachycondyla striata, one of the most frequent attendants to lipid-rich arillate diaspores, transported the latter into their nests and discarded clean intact seeds on refuse piles outside the nest. Germination tests with cleaned and uncleaned diaspores revealed that the removal of pulp or aril may increase germination success in Virola oleifera, Cabralea canjerana, Citharexylum myrianthum and Alchornea glandulosa. Gas chromatography analyses revealed a close similarity in the fatty acid composition of the arils of the lipid-rich diaspores and the elaiosome of a typical myrmecochorous seed (Ricinus communis), corroborating the suggestion that some arils and elaiosomes are chemically similar. Although ant-derived benefits to diaspores - secondary dispersal and/or increased germination - varied among the six plant species studied, the results enhanced the role of ant-diaspore interactions in the post-dispersal fates of nonmyrmecochorous seeds in tropical forests. The size and the lipid-content of the diaspores were shown to be major determinants of the outcome of such interactions.

Prevenção de hemoglobinopatias a partir do estudo em gestantes

The Brazilian population, presents genes for abnormal hemoglobins with variable frequencies, which are influenced by the founding racial groups. Thus, the detection of carriers of the genetic alterations is important for public health, since they represent sources of new beterozygotes and possible homozygotes. The control of the hemoglobin pathologies has been possible by means of genetic counseling and early diagnosis. The clinical follow-up of the homozygotes and the orientation of the beterozygotes and especially the couples at risk represent a more effective mode of acting to avoid the birth of children who are carriers of a genetic disease, that is frequently lethal. For these reasons this work had as its objectives: to evaluate the importance of testing in pregnant women for the detection of hemoglobin pathologies with the purpose of investigating the prevalence, attaining prevention, a familial study and awareness; for the positive cases such as couples at risk, orient as to appropriate medical attendance; and to evaluate the response to the program. Of the total of 696 pregnant women analysed, 10.7% revealed hemoglobin pathologies with the following rates: alpha Thalassemia 6.75%; Hb AS 2.01%; beta minor Thalassemia 1.29%; Hb AC 0.28%; Hb AJ 0.14%; Hb AS/Alpha Thalassemia 0.14% and P.H.H.F. 0.14%. The high rates of hemoglobin pathologies encountered in the population of pregnant women studied shows the necessity of the implantation of tests for these abnormalities in the pre-natal routine, since in this period the mothers are more apt to be preoccupied with their own health and that of their babies and, however earlier diagnosed the alterations in the hemoglobins, better and more adequate will be the orientations given the couple.

Perfil demográfico e de morbidade da população idosa atendida nas dependências do pronto-socorro, ambulatórios e enfermarias no HC-Unesp em 1997

Being our objective to characterize demographic and morbidity patterns of the 60 years old or more attended at the UNESP Clinic Hospital in 1997 a sample consisting of 482 handbooks has been analyzed in order to evaluate ambulatory attendance, other consisting of 101 handbooks to evaluate first aid clinic demand and statistics from Medical Informatic Center (Centro de Informática da Medicina - CIMED) refering to 2652 internments of such populations this year. Ten and a half per cent from the total of first aid clinic attended patients refers to this old people and the majority (57,4%) lives in Botucatu County. More frequently diagnoses during consultation are Chronic Obstructive Lung Disease (10.1%), Congestive Cardiac Disease (4.7%), Asthma and Cataract (3.1 % for both). Such population is also referred to be 19.8% from the number of all patients attended at the UNESP ambulatories, 65.8% coming from other city in São Paulo State, being in average 69.6 years old and attending 4.5 consultations in average by year. More frequently found diagnoses referred to Essential Primary Hypertension (4.2%), Prostatic Nodular Hyperplasia (4.0%) and Nonspecified Cataract (3.3%). Regarding to internments, they referred to be 18.4% from the number of all interned patients. More frequent diagnoses at internmemt referred to Nonspecified Cataract (12%), Glaucoma (3.0%), Prostatic Nodular Hyperplasia (2.4%) and Limbs Arteriosclerosis (2.3%). Results indicates the existence of an tertiary hospital divided into specialties, also attending morbidity that should be in control into levels of primary and secondary attention.

A família do portador de sofrimento psíquico e os serviços de saúde mental: Estudo de caso

This qualitative research, case study type, aimed at presenting the understanding of psychic sufferers in search for mental health services during emergency situation, partial hospitalization or in ambulatory services. 12 family members were interviewed. They reported difficulties in the attendance in the emergency room when the patient is in crisis, as well as doctors considering merely the present symptomatology and undervaluing their own knowledge of the sickening process. The day-care hospital is conceived as a place to provide care, occupation and should teach as a school. The ambulatory service represents for the family the possibility of the patient being responsible for their attendance to the consultations and for the correct use of the medication.

Desenvolvimento motor de criança com paralisia cerebral: Avaliação e intervenção

The objective of this study was to analyze the motor development of a ten year old child with ataxic cerebral palsy and the effects of a motor activities program in the swimming pool. Motor development was measured according to the motor assessment and the intervention program of motor activities in the swimming pool conducted at Sesi/Londrina, twice a week, during 45 minute sessions over a 2 month period, with an attendance rate of 87%. Data was analyzed descriptively comparing the results with before and after tests. Generally, the motor quotient regarding all items was classified as very low, characterizing motor deficit, with exception of temporal organization, presented as normal low. After intervention, the only area that showed positive change was balance; this result showed that the child gained 12 months in motor age, without corresponding alterations in the other areas.

Drug dependence, mental impairment and education

This study aimed to evaluate the mental conditions of cocaine-dependent individuals and school commitment/attachment. We evaluated 50 patients referred to the psychiatry emergency room due to mental disorders from chemical dependence. After clinical diagnosis, clinical interview, Hospital Anxiety and Depression Scale, Hamilton Scale for Depression and Brief Psychiatric Rating Scale were applied. The Spearman and Mann-Whitney nonparametric tests, as well as the t-Student test were utilized for statistical analysis.. The accepted significance value was 0.05. All subjects had used cocaine or crack and other substances. Only 13 (26%) did not drop out of school (group 1). Regarding the other 37 (74%), irregular class attendance , successive failures and definitive school drop out rates (group 2) were verified. These subjects presented an early substance use when compared with those which did not drop out of school (p=0.0001). Patients with an early substance use presented higher school dropout rates than those with a later initiation to substance use. Psychopathological phenomena were frequent in both groups.

A video-based biometric authentication for e-learning web applications

In the last years there was an exponential growth in the offering of Web-enabled distance courses and in the number of enrolments in corporate and higher education using this modality. However, the lack of efficient mechanisms that assures user authentication in this sort of environment, in the system login as well as throughout his session, has been pointed out as a serious deficiency. Some studies have been led about possible biometric applications for web authentication. However, password based authentication still prevails. With the popularization of biometric enabled devices and resultant fall of prices for the collection of biometric traits, biometrics is reconsidered as a secure remote authentication form for web applications. In this work, the face recognition accuracy, captured on-line by a webcam in Internet environment, is investigated, simulating the natural interaction of a person in the context of a distance course environment. Partial results show that this technique can be successfully applied to confirm the presence of users throughout the course attendance in an educational distance course. An efficient client/server architecture is also proposed. © 2009 Springer Berlin Heidelberg.

Evaluación de las metodologías de enseñanza-aprendizaje de la bioética en las facultades de odontología Brasileñas

Introduction. Bioethics is present in Dentistry and other health areas, as scientific research that results on profession progress, as in proper clinical attendance. The study consists on valuation of teaching-learning methods of Bioethical on Brazilian Dental Schools. Materials and methods. Data collect occurred by semi-structured questioners send by e-mail and correspondence. It was realized descriptive analysis of quantitative answers, and for qualitative answers, it was used content analysis, by categorical analysis technique in according to Bardin. Results. Among 182 Dental Schools actives in Brazil, only 57 (31.3%) showed bioethical discipline in its curricular grid. It was observed the discipline is teaching on theoretical form (77.8%). Principal forms of evaluation are: writing prove (100%) and seminaries (75%). Just 6.4% of professors use bibliographic references about bioethical faced to Odontology specifically. The majority of interviewed person (74.2%) considered that bioethics is related on the direct and indirect form with all others disciplines. In relation to importance of Bioethical on dental surgeon formation, 64.7% emphasized it in professional-patient relation. Conclusion. The Bioethics show teaching and practice method of conserver evaluation, and so, it's necessary others methods directed to reflection of actual problems in odontology area that contribute significantly on integral formation of dental surgeon. © Viguera Editores SL 2009.

Longitudinal behavioral analysis during dental care of children aged 0 to 3 years

Abstract: When and how the dentist intervenes have repercussions on children's physical and emotional patterns. The objective of the present study was to conduct a longitudinal behavioral analysis during dental care of babies aged 0 to 3 years. A total of 216 patients seen at the Baby Clinic of the School of Dentistry at Araçatuba, São Paulo State University (UNESP), were selected. The selection criterion was attendance at ten dental care sessions at bimonthly intervals for routine procedures such as clinical examination and oral hygiene. There was a predominance of cooperative behavior compared to uncooperative behavior when each visit was analyzed separately. The behavior of the patients must have been directly influenced by their psychomotor development. Constant attendance and exposure of the baby to non-stressful dental stimuli are factors that favor a cooperative behavior.

Controle de qualidade da raiz de Operculina macrocarpa (Linn) Urb., Convolvulaceae

Considering the quality of the phytotherapic agents, it is important to point out that it includes rigorous attendance of the different steps of the development and production of these products, from the collection of the vegetable to the availability of the final product. In this work the quality control of the Operculina macrocarpa (Linn) Urb. roots, popularly known as 'batata-de-purga', was carried out. Pharmacopoeic and no pharmacopoeic methodologies were employed to physico-chemical and microbiological quality control. The obtained results showed that the roots presents a content of resin of 9,85%, The microbiological analysis did not present pathogenic growth among the other accomplished tests. The work stands out the importance of the establishment of norms for the quality control for the plants, so that they are found able to be used for phytotherapic reasons.

Sistema de Informação Pré-Natal: análise crítica de registros em um município paulista.

The prenatal assistance is one of the health care pillars. This study aimed to conduct a critical evaluation of the SIS Prenatal in a city of São Paulo State, to compare its data with the local assistance and to verify the registry of pregnant women attended at Health Care Centers. It was analyzed the pregnant women records through consultation at Health Regional Unit and municipal health service. There were inconsistencies between the system and local registry. The failures were related to the inadequate filling of attendance files, besides scarce control of pregnant women files and scheduling on health centers. The results suggest the need for better planning of actions for the improvement of prenatal service quality.

Conhecimento Odontológico e Comportamento de Retorno de Escolares em Função do Tipo de Instituição (Pública ou Privada)

Objective: To evaluate the dental knowledge and attendance of elementary schoolchildren according to the type of institution (public or private). Method: The sample was composed of 800 children from the 5th to 8th grades of the elementary education. The research instrument was a questionnaire composed of open questions referring to the last recall visit, type and importance of the recall visit, and knowledge of dental caries and periodontal disease. Descriptive statistical analysis was done and the chisquared test was used with a significance level of 5%. Results: There was statistically significant difference between the students from the different institutions regarding the time (p=0.001) and main reason (p=0.001) of the last visit to the dentist, knowledge of the need of periodic visits to the dentist (p=0.001), importance (p=0.001) and frequency (p=0.001) of periodic recalls, and knowledge of dental caries (p=0.001) and periodontal disease (p=0.001). Conclusion: The adolescents presented different dental knowledge and attendance, according to the type of teaching institution.

Educação a distância e formação continuada do professor

Distance Education has had a significant role in further teacher development. The aim of this study was to collect and analyze data related to distance education for the further teacher development related to the inclusion process of people with disability. One hundred and eighty two students from the Distance Training course from Unesp - Bauru / SP participated in the research, constructing and applying a semi-structured questionnaire. The results indicate that scheduling flexibility and attendance of a great number of students in different geographical areas stand out as positive points of this modality, however, for it to be a success, tutors must be adequately prepared to use new tools in the teaching-learning process. It is essential that the students feel they are being assisted in every moment, contributing to the construction of a virtual community and effecting quality development in distance education.
