Selected AbstractsA Model for Mapping Linkages Between Health and Education Agencies to Improve School HealthJOURNAL OF SCHOOL HEALTH, Issue 2 2000Lawrence St. Leger ABSTRACT: Efforts to develop effective and sustainable school health programs evolved in sophistication the past 20 years through research and practical experience. This paper reviews these developments, arguing they were significantly driven by public health priorities, and have not adequately accounted for educational perspectives and priorities. To better understand the differences in perspective, a model is presented which illustrates linkages between different school-based inputs and strategies, and long-term health and educational outcomes. The model describes similarities and differences between the two perspectives. A significant coincidence exists in factors that determine educational attainment and improved health outcomes for students. A more holistic and integrated approach to school health is emerging, and at these interfaces our implementation and research efforts for the 21st century should be concentrated. [source] Dental fluorosis in primary teeth: a study in rural schoolchildren in Shaanxi Province, ChinaINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 6 2005J. P. RUAN Summary. Objective. The aim of this study was to assess the prevalence and severity of fluorosis in the primary dentition of 7,8-year-old Chinese schoolchildren in areas with fluoride concentrations in the drinking water ranging from 0·35 to 7·6 mg L,1. Subjects and methods. Four hundred and seventy-two children from 13 different schools were divided into four groups according to the fluoride concentration of the drinking water: (A) , 1·0 mg L,1; (B) 1·1,2·0 mg L,1; (C) 2·1,3·8 mg L,1; and (D) 7·6 mg L,1. Clinical examinations were made under field conditions, and dental fluorosis on the buccal surfaces of all teeth was recorded using the Thylstrup,Fejerskov Index (TFI). Results. The prevalence of dental fluorosis in primary teeth varied from 6·2% to 96·6% according to the fluoride concentration of the drinking water. The differences of median of TFI scores between all groups were statistically significant (P < 0·001) except for groups B and C. No statistically significant difference in the severity of dental fluorosis was observed between genders. The second primary molars were most severely affected by dental fluorosis. Disregarding group A, TFI scores between 3 and 4 were most frequently recorded. Dental fluorosis was symmetrically distributed in both jaws. Conclusion. Dental fluorosis is prevalent in the primary teeth of children living in areas supplied with drinking water with fluoride concentrations higher than 1·0 mg L,1. The primary teeth may act as biomarkers of fluoride exposure. The examination of primary teeth may give an early warning of this condition, and thus, provide a basis for intervention to prevent dental fluorosis in the permanent teeth. [source] Prevalence of celiac disease among school children in Punjab, North IndiaJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 10 2006Ajit Sood Abstract Background:, Celiac disease, as of today, is said to exist in almost all parts of the world, although it is rare among people of purely African,Caribbean, Japanese and Chinese background. The disease has also been considered uncommon in India until recently. Hospital records have revealed an increasing trend of the disease in predominantly wheat-eating areas of North India. The aim of the present study was to determine the prevalence of celiac disease among school children in Punjab, North India. Methods:, The study was carried out in the Ludhiana district of Punjab, Northern India. A total of 4347 children aged 3,17 years attending different schools were enrolled. A structured questionnaire was used to collect sociodemographic data and symptoms and signs related to celiac disease and various sociodemographic factors. The screening for celiac disease for the suspected celiacs was done by testing for antitissue transglutaminase (anti-tTG) by indirect solid-phase immunometric assay (ELISA). All children with high anti-tTG whose parents consented underwent upper gastrointestinal endoscopy for small bowel biopsy from the second part of the duodenum. Histopathology was expressed according to the Marsh classification of 1992. Follow up was carried out among children who were put on a gluten-restricted diet, at monthly intervals for 3 months and every 3 months thereafter. The diagnosis of celiac disease was established on the basis of the revised European Society of Paediatric Gastroenterologists and Nutritionists (ESPGAN) criteria (confirmed cases). Results:, A total of 4347 school children (1967 girls, 2380 boys, age range 3,17 years) were screened for celiac disease. Out of these, 198 suspected children were identified for further evaluation. Twenty-one children tested positive for anti-tTG assay (10.6%, 95% confidence interval: 16.91,34.79). Seventeen of these 21 children agreed to undergo biopsy; of these, 14 had histological changes consistent with celiac disease and all these 14 children had clinical response to gluten restriction. Three children with high anti-tTG had normal mucosa on duodenal biopsy and were not labelled as being in the celiac disease group. In the final analysis the disease prevalence was one in 310 children. Conclusions:, This is the first study on celiac disease prevalence among school children from India. Although this disease frequency of one in 310 is thought to be an under-assessment, it clearly shows that celiac disease is not rare in wheat-eating areas of North India. [source] Relative power and influence strategy: the effects of agent/target organizational power on superiors' choices of influence strategiesJOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 2 2002Anit Somech The present study examined superiors' tendency to utilize different top,down influence strategies according to their evaluation of their own power relative to that of their subordinates. Four hundred and fifty-five subordinates (schoolteachers) from different schools described the extent to which their superiors used each item of the influence strategy questionnaire to influence them, while their immediate superiors evaluated superior's power and subordinate's power. Overall, superiors tended to use soft and rational strategy more often than hard strategy. However, regarding the parameter of relative power, the results indicated that the agent's power, as well as the target's power, affected the superior's choice of particular influence strategy. The results suggest that power should be discussed in relative rather than absolute terms. Copyright © 2001 John Wiley & Sons, Ltd. [source] Assessment of Dental Caries Predictors in a Seven-year Longitudinal StudyJOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 3 2006Elaine Pereira da Silva Tagliaferro DDS Abstract Objective: To identify, in a group of 6,8-year-old schoolchildren, risk factors for dental caries increment in permanent dentition. Methods: Two hundred and six children from three different schools in Piracicaba, Brazil, were examined at baseline and after 7 years by the same two calibrated dentists. Data on dental caries (dmfs, DMFS, presence of initial lesions), fluorosis, oral hygiene and presence of sealant were collected at the clinical examination that was performed in an outdoor setting, under natural light, using a dental mirror and probe following the WHO recommendations. Information on socioeconomic level, fluoride usage, dental service utilization, dietary and oral hygiene habits was also obtained at baseline in a semi-structured questionnaire sent to the parents. The dependent variable was the 7-year DMFS increment. A univariate analysis was performed to test the association of independent variables in caries increment. Then a logistic regression model was used to estimate the adjusted Odds Ratio for caries increment. Results: Clinical (dmfs, DMFS) and non-clinical variables (daily toothbrushing, use of preventive topical methods, parents' educational level) were entered in the multiple logistic regression analysis. The prediction model included the clinical and socioeconomic variables, DMFS, dmfs and mother's educational level. The best caries predictor was the dmfs variable. Conclusion: Caries experience and mother's educational level were predictors of caries increment in permanent dentition. [source] Civil-Military Affairs and Security Institutions in the Southern Cone: The Sources of Argentine-Brazilian Nuclear CooperationLATIN AMERICAN POLITICS AND SOCIETY, Issue 4 2004Arturo C. Sotomayor Velázquez ABSTRACT This paper analyzes the conditions in which the governments of Argentina and Brazil founded security institutions in the early 1990s, while they were democratizing. It advances the hypothesis that international cooperation in the security field is often linked to the evolution of civil-military relations. Civilian leaders in both countries established institutions and sought international participation deliberately to achieve civilian control and gain leverage over the military establishment, which they sorely distrusted. The need to stabilize civil-military relations at home was therefore the prime motivating force behind the emergence of security institutions in the Southern Cone. Three mechanisms were at work: omnibalancing, policy handling, and managing uncertainty. These mechanisms are derived from three different schools of thought: realism, organizational-bureaucratic models, and theories of domestic political institutions. Besides explaining the sources of nuclear bilateral cooperation, this argument also serves as a critique of two prominent theories in international relations that attempt to explain cooperation and peaceful relations among democracies: neoliberal insti-tutionalism and democratic peace theory. [source] Crime scene investigation: An exercise in generating and analyzing DNA evidence,BIOCHEMISTRY AND MOLECULAR BIOLOGY EDUCATION, Issue 1 2003Karen M. Lounsbury Abstract The goal of this project is to introduce students to molecular biology techniques using an experimental setting that inspires both scientific and personal interest. The project is designed as a small group apprenticeship for gifted high school juniors or seniors who can spend full time in a sponsor's laboratory for at least 1 week. The students begin by examining evidence from a mock crime scene that consists of hair samples from the crime scene and from five potential suspects. Students extract DNA from the hair samples and amplify a hypervariable region within the mitochondrial genome using the polymerase chain reaction. Amplified products are then sequenced and compared with the crime scene sequence using DNA alignment software. In consecutive projects, students from four different schools successfully identified the suspect who matched the crime scene evidence. This project is a valuable learning tool not only due to the comprehensive introduction to molecular biology techniques but also because it helps the students to connect scientific exploration with well publicized media events and provides a window into potential career opportunities in the field of molecular biology.
