Disease prioritarianism is a principle that is often implicitly or explicitly employed in the realm of healthcare prioritization. This principle states that the healthcare system ought to prioritize the treatment of disease before any other problem. This article argues that disease prioritarianism ought to be rejected. Instead, we should adopt ‘the problem-oriented heuristic’ when making prioritizations in the healthcare system. According to this idea, we ought to focus on specific problems and whether or not it is possible and efficient to address them with medical means. This has radical implications for the extension of the healthcare system. First, getting rid of the binary disease/no-disease dichotomy implicit in disease prioritarianism would improve the ability of the healthcare system to address chronic conditions and disabilities that often defy easy classification. Second, the problem-oriented heuristic could empower medical practitioners to address social problems without the need to pathologize these conditions. Third, the problem-oriented heuristic clearly states that what we choose to treat is a normative consideration. Under this assumption, we can engage in a discussion on de-medicalization without distorting preconceptions. Fourth, this pragmatic and de-compartmentalizing approach should allow us to reconsider the term ‘efficiency’.  相似文献

This study examined the effect of caries disclosing dyes on composite to dentin shear bond strengths of a total etch, one-bottle and two self-etching, non-rinsing primer dental adhesives. Two caries disclosing dyes were evaluated, Seek and Snoop, with three dentin adhesives, Prime & Bond NT, Prompt L-Pop and Clearfil SE Bond. Extracted human molars stored in 0.2% sodium azide were sectioned longitudinally to expose dentin and embedded in acrylic, leaving the dentin exposed. Each dentin adhesive had three test groups (n=12); a control and one with each of the caries disclosing dyes. The control group had the dentin conditioned and the adhesive applied following the manufacturer's instructions. The caries disclosing dye groups had the dentin first treated for 10 seconds with the disclosing dye, rinsed, then the dentin adhesives were applied as in the controls. A column of Tetric Ceram was bonded after dentin adhesive placement to each specimen and light cured. Specimens were stored in room temperature water for 24 hours, thermocycled for 1,000 cycles between 5 degrees C and 55 degrees C and tested in shear until failure. Mean +/- SD shear bond values (SBV) were determined in MPa. A one-way ANOVA and Student Neuman Keuls multiple comparison test within each DBS were performed at a significance level ofp<0.05 to analyze the caries disclosing dyes input on SBV versus the controls. Surface analysis to determine the nature of the type of dentin/composite fracture/ separation was also performed. For the fracture analysis data, a Chi-Square test was performed at a significance level of p<0.05. The results of this study indicate that using the two tested caries disclosing dyes, with a total etch, one bottle and two self-etching, non-rinsing primer dental adhesives did not negatively affect the dentin-to-composite shear bond strengths of the three tested dentin bonding systems (p>0.05).  相似文献

The extensive destructive potential of the keratocyst has been well recognized but penetration of the keratocyst into the skull base is rare.3 cases showing such aggressive behavior and rare location were seen and treated; 2 are reported in this paper. Both cases illustrate the importance of early radical treatment once the aggressive nature of keratocyst is recognized.  相似文献

BACKGROUND: Improved treatment of sexually transmitted infections (STIs) is associated with decreased HIV incidence. However, the success of such programs among HIV-positive sex workers has not been shown.GOAL The goal of the study was to determine the incidence of STIs ( and infections) among HIV-positive sex workers. STUDY DESIGN: A cohort of HIV-positive sex workers was treated for all STIs at baseline and observed monthly to detect and treat new infections. RESULTS: Seventy-seven HIV-positive sex workers were followed up for a total of 58.1 women-years. The incidence rate per 100 women-years was 150 (CI: 120-180) infections; 66 (CI: 45-87) infections; 30 (CI: 14-42) infections; and 244 (CI: 200-280) STIs of any type. CONCLUSION: In this cohort of HIV-positive sex workers the incidence of STIs was high, despite their participation in a prevention program comprising monthly STI treatment, counseling, and condom promotion.  相似文献
