TL;DR: In this article, the geochemistry of residual soils from relatively fluoride-rich ( 2 O 5 are depleted, suggesting that the loss of CaO provides favorable conditions for the leaching of F to water) district are enriched in TiO 2, Fe 2 O 3, MnO, Cr, V and Sc.

TL;DR: Serum calcium may be considered a risk factor for periodontal disease progression in non-institutionalized elderly.
Abstract: OBJECTIVE To assess the effect of baseline serum calcium on the progression of periodontal disease in non-institutionalized elderly. BACKGROUND Although a few studies have found some evidence of the role played by dietary calcium in periodontal disease process, there is a paucity of information pertinent to longitudinal assessment of serum calcium-periodontal relationships. MATERIAL AND METHODS Clinical attachment levels of 266 Japanese subjects aged 70 years were recorded at baseline and annually for six consecutive years. Progression of periodontal disease (PPD) was defined as the number of teeth that showed additional attachment loss of > or =3 mm during the 6 years. The number of PPD was calculated for each subject and categorised into four levels, namely, PPD(0), PPD(1), PPD(2) and PPD(3) where the number of teeth with additional attachment loss ranged from 0, 1-10, 11-20 and >20 respectively. The levels of serum calcium, albumin, random blood sugar, immunoglobulin (IgG, IgA and IgM), gender, smoking habits, education, gingival bleeding and the number of teeth present were obtained at baseline. RESULTS Serum calcium, IgA, smoking, gingival bleeding and teeth present were associated with PPD at p < or = 0.10 and were included in a multinomial logistic regression analysis. Serum calcium was the only variable that was significantly associated with PPD with relative risks of 100 at PPD(1) and PPD(2), respectively, and 1000 at PPD(3). CONCLUSION Serum calcium may be considered a risk factor for periodontal disease progression in non-institutionalized elderly.

TL;DR: A comprehensive hydrogeochemical study was carried out to reveal the processes affecting the groundwater quality in the Jaffna Peninsula of Sri Lanka as discussed by the authors, where major and trace element composition and environmental isotope ratios of oxygen and hydrogen were determined in 35 groundwater samples for this investigation.

TL;DR: It is essential to engage with local communities to understand their concerns and attitudes as well as develop partnerships that can mobilize support and action to address this problem.
Abstract: Road traffic injuries and associated deaths have reached epidemic proportions in Sri Lanka, resulting in 2,000 deaths and 14,000 injuries each year. Accurate information on the patterns and trends in fatal and non-fatal outcomes are essential to identify emerging issues relating to vulnerable road user groups. This information is also needed to raise community awareness, prioritize public action, mobilize and allocate resources for intervention, and monitor the impact of road safety programmes. Another important gap relating to road traffic injury in Sri Lanka is the scant data regarding the determinants and consequences of road traffic injuries. It is essential to engage with local communities to understand their concerns and attitudes as well as develop partnerships that can mobilize support and action to address this problem. At the national level, a lead government agency, for example the Ministry of Health, should be identified and empowered to guide and coordinate inter-sectoral road traffic injury prevention efforts. The response must include a systematic approach to assessing the problem and addressing research gaps. The initiatives developed must provide the necessary evidence to develop context-relevant actions that can prevent road crashes and minimize the consequences of road traffic injuries.

TL;DR: This comprehensive literature review on oral epithelial dysplasia summarizes the scientific knowledge published in the scientific literature in English since its first description.
Abstract: Oral epithelial dysplasia is a spectrum of architectural and cytological epithelial changes caused by accumulation of genetic changes, and is associated with an increased risk of progression to squamous cell carcinoma. It is a microscopic diagnosis of immense clinical importance. The initial reports of oral potentially malignant disorders with oral epithelial dysplasia transforming to oral cancer helped in understanding the nature of oral malignancies. Since then, clinical studies on oral potentially malignant disorders have combined microscopic findings of oral epithelial dysplasia to assess the malignant transformation potential of different grades of epithelial dysplasia. A significant amount of scientific literature has amassed on oral epithelial dysplasia relating to aspects of its diagnosis and management. However, the evidence base is weak as a result of the significant variability of published research. Poorly described study methods, variability in different oral epithelial dysplasia grading systems, inter- and intra-examiner variability causing issues of reliability, inadequate sample size, and inconsistent durations of follow-up are some of the methodological issues contributing to the failure to provide dependable information. Randomized clinical trials on the malignant transformation potential of oral epithelial dysplasia and its treatment outcomes are limited. This comprehensive literature review on oral epithelial dysplasia summarizes the scientific knowledge published in the scientific literature in English since its first description. The historical development, etiological factors, grading systems, diagnostic criteria, assessment of risk factors and prevention of malignant transformation, management principles of different grades of oral epithelial dysplasia (surgical and nonsurgical), recommendations on follow-up, and prognostic indicators are discussed in detail.
