The visit of Dr. Trendley Dean to Dublin in the mid-1950s helped accelerate the decision to introduce water fluoridation as a public health measure in the prevention of caries in the Republic of Ireland. A challenge to the constitutional validity of the Health (Fluoridation of Water Supplies) Act 1960 failed and in 1964 the water supplies of Dublin city were fluoridated. Over the next seven to eight years all the major urban communities in the Republic of Ireland were fluoridated. Currently, 67 percent of the 3.5 million people in the country reside in fluoridated communities. Studies conducted over the last 20 years show that residents of fluoridated communities have better dental health than those in nonfluoridated communities—the mean dmft is lower in children and the number of natural teeth present in adults is higher.  相似文献

ISSUES AND PURPOSE. To identify the ethical and legal implications of conducting research with homeless adolescents and to discuss guidelines for conducting research without parental consent.
CONCLUSIONS. Ethical principles of capacity, risk, postponement, and truthful disclosure within the context of the rights of minors to consent to healthcare treatment form the basis of the argument for allowing adolescents to consent to participate in research without parental consent when there is minimal risk or when such consent could place them at increased risk for harm.
PRACTICE IMPLICATIONS. Adolescents who are the target population for clinical research or who are intended recipients of nursing care should be involved in setting priorities, purposes, and protocols. Parents and other adults from their communities should be included in developing strategies to protect their confidentiality and privacy while helping them achieve autonomy in making informed health-related decisions.  相似文献

Filiation, or a person's parentage, is one of the major componentsof someone's identity, often with important implications forthat person's welfare in social and personal terms. Fertilityspecialists are enjoined to consider the welfare of the child,and this is a legal requirement in assisted reproduction techniquesin the UK. This paper is in three parts, discussing some ofthe potential problems regarding filiation of the prospectivechild born of assisted reproduction techniques, in relationto the use of gametes and embryos. The first two parts concentrateon the status of children born as a result of treatment givenposthumously, and on filiation problems associated with donationof gametes or embryos, and surrogacy. The third part comparesBritish and French legislation with special regard to the welfareof the child, as well as underlining the common trends and principlesenunciated in both legislations. This is particularly appropriateat a time when the European Society for Human Reproduction andEmbryology is about to issue ethical guidelines in assistedreproduction, and when both the Council of Europe and the EuropeanCommission have commissioned studies on the implications ofthe assisted techniques, including those concerning status ofthe potential children.  相似文献

This report aims to encourage optometrists to reflect on the legal implications of clinical contact lens practice, with particular reference to the practice of orthokeratology (ortho-k), which has seen a recent revival of interest. A patient may claim compensation if an optometrist is negligent by breaching his duty to exercise reasonable care and skill in diagnosis, advice or treatment. However, the optometrist will only be liable for reasonably foreseeable harm to the patient, so practitioners need to be fully aware of the foreseeable risks. Failure to adequately inform the patient may lead to a claim for negligence, if disclosure of the risks would have influenced the patient's decision to undergo or forego the procedure. It is important that the professional bodies establish guidelines on acceptable practice, with particular emphasis on the provision of information to patients. Reasonable disclosure, use of appropriate information/consent forms, and proper documentation of cases, should all focus on the needs of, and benefits to, patients.  相似文献

Harm reduction in the developing world   总被引:1,自引:0,他引:1  
This paper examines harm reduction from the perspective of poor countries. In considering which elements of the broad approach are suitable for adaptation and adoption by poor countries, there is a need to examine critically the arguments put forth in support of it and which, if any, of these are supported by evidence. There are also significant indirect influences that the approach is likely to have on how drug use is understood and interpreted by wider society. The likely impact of these on areas other than simply services directed to drug users needs to be assessed. There are some features regarding harm caused by alcohol and other drug use that are specific to poor countries. Most important among these is that levels of use which are not deemed to be harmful in rich societies cause grave harm through diverting meagre resources away from survival needs in the poor world. Alcohol, as well as other drugs, tends in deprived settings to cause dependence and other problems much earlier in people's drinking careers and at much lower levels of consumption than in rich countries.  相似文献

由于我国医疗事故赔偿纠纷处理的有关法律、行政法规及司法解释之间存在着不统一、不配套的矛盾。因此,在审理医疗事故赔偿纠纷案件中的分歧颇大 这既不利于正确地维护医患双方的合法权益,也不利于医疗纠纷的顺利解决及社会秩序的稳定。因此,正确地认识与解决医疗事故赔偿纠纷法律适用中的矛盾,具有十分重要的意义。  相似文献
