Fractional resurfacing or laser therapy (FLT) represents a technology that seeks to address the limitations of both ablative resurfacing and nonablative treatments. Many companies now offer versions of fractionated erbium or carbon dioxide lasers. The purpose of this paper is to examine FLT for difficult to treat applications such as melasma, acne scarring, atrophic scarring, striae distensae, and deep rhytides. Fractional laser therapy is a truly novel approach to many conditions, especially those with dermal pathology. Although published peer review data is limited, the ability to effectively and safely treat these conditions in all skin types appears to have been significantly enhanced with this new modality. We are early in our scientific explorations of what is possible with FLT. 相似文献

Publication of presented abstracts at annual scientific meetings: a measure of quality? 总被引:4,自引:0,他引:4
One measure of the quality of research presented at the annual scientific meeting is publication of the data presented in a peer review journal. This allows for a more rigorous review of design, methodology and conclusions. To determine the rate of subsequent publication, MEDLARS searches were performed on the 269 presented abstracts at the 1984 and 1986 meetings of the American Association of Poison Control Centers, The American Academy of Clinical Toxicology, The American Board of Medical Toxicology and the Canadian Association of Poison Control Centers. Of the 296 presented abstracts, 134 (49.8%) were published. There was no difference in the eventual publication rate between the 1984 and 1986 meeting. There were 38 non-reviewed symposia publications and 96 peer-reviewed articles. Publications of 35.7% of presented abstracts in peer review journals compares poorly with the percentage of peer-reviewed publication from other scientific meetings. If publication in a peer-review journal is important, steps should be taken to improve the percentage of presented abstracts that are accepted by peer-review journals. 相似文献

OBJECTIVE: A relatively new approach to addressing tobacco use in mental health settings is the involvement of consumers or peers, defined as other individuals with mental health conditions, as service providers. This review examines the literature describing peer delivered supports for tobacco cessation for adults with serious mental illness. METHODS: The authors conducted a review of online databases to identify reports of tobacco cessation interventions in which peers play a key role in the provision of services to help other adults with serious mental illness to reduce or quit using tobacco. RESULTS: Our review yielded reports of four tobacco cessation interventions for persons with serious mental illness that include peer providers. The roles of peers in these interventions include that of co-leaders of an educational smoking cessation group, individual counselors as part of a multi-faceted tobacco treatment program, and as outreach tobacco cessation advocates. CONCLUSIONS: The roles of peers in these interventions are promising; however, more detail about the selection and experience of the peer providers, as well as the services they deliver in tobacco cessation interventions, would be helpful. In addition, rigorous research is needed to evaluate the impact of peer providers on reducing tobacco use in this population. 相似文献

组织病理学评估是药物非临床安全性评价的重要环节,组织病理学同行评议不仅可以确保诊断术语的一致性和准确性,而且可以提高病理诊断的准确性和病理学报告的质量。因为GLP质量体系的核心是原始数据,所以要确保最终病理学报告能够真实反映原始数据。组织病理学评估和同行评议的原始数据是病理学报告重建和保证报告质量的基础。本文对国内外GLP法规对原始数据的定义、美国FDA对病理学原始数据的规定、国内外监管机构对组织病理学同行评议中原始数据的规定、不同类型组织病理学同行评议中的原始数据以及组织病理学同行评议的GLP符合性进行分析,希望为我国GLP机构更好地开展组织病理学评估及同行评议提供一定参考。 相似文献

The development and implementation of a peer review quality assurance program for a drug information service is described. Eight drug information centres across Canada initially agreed to participate as peer reviewers. Critera were developed to select drug information requests that would qualify for the program. Peer review responses were compared to the centre's response by a panel of four drug information pharmacists. Thirteen of 14 requests sent to peer reviewers were returned and there was agreement between the conclusions and recommendations provided in the responses by our drug information centre and the peer review pharmacist in 11 cases. Peer reviewer pharmacists tended to prepare more in depth responses. This represents the first report of a peer review quality assurance program for a drug information service. 相似文献

The Soft Tissue and Bone Sarcoma Group (STBSG) of the EORTC ran a phase II study to assess the therapeutic activity of high-dose ifosfamide in patients with advanced soft tissue sarcomas by means of response rate (RR). Investigators claiming a response submitted the relevant chest radiographs (CXR) or scans to two other members of the STBSG for peer review. The reviewers completed a questionnaire indicating overall response or reasons for rejecting the claimed responses. An independent radiologist also reviewed the cases and he was blinded to the results of the peer review until the study was concluded. Twenty-two patients were reviewed by the radiologist and peer review, and the completed questionnaires were retrospectively reviewed. Two differences were noted, one partial responder (PR) was regarded as stable disease by the radiologist and one PR by peer review was determined a complete response by the radiologist. The radiologist found subsequent evidence of progressive disease in three patients who initially showed a PR, whilst the review group noted only one. This study suggests peer review in this tumor type is a satisfactory method of achieving an accurate, objective RR. 相似文献

The present research assessed racial differences in the associations among controlled orientation, injunctive norms, and increased drinking by White and Asian American college students. Previous research has noted racial differences in drinking, but reasons have not been considered in the context of individual differences in self-determination or responses to social influences. The authors evaluated perceived parental and peer injunctive norms as mediators of the relationship between controlled orientation and number of drinks consumed per week. The association between controlled orientation and drinking was further expected to be moderated by race. This study consisted of 534 White and 198 Asian American participants who had at least one heavy drinking episode in the month prior to assessment. Participants completed self-report measures assessing self-determination, perceived parental/peer injunctive norms, and drinking. Results indicated that peer injunctive norms served as a mediator between controlled orientation and greater number of drinks consumed per week for Whites only. Although Asian Americans were significantly higher in controlled orientation than Whites, they drank less and perceived their peers to be less approving of drinking. In contrast, Whites who were high in controlled orientation viewed their friends as being significantly more approving of alcohol and consumed significantly more drinks per week. Results provide unique considerations for understanding cultural differences in drinking among White and Asian American young adults. 相似文献

The NTP is an interagency program of the Federal Government which coordinates toxicological programs at the NIH (NIEHS), FDA (NCTR), and CDC (NIOSH) with input from NCI, NIH, OSHA, CPSC, EPA, and ATSDR. The NTP has the capability to completely characterize the toxicologic profile of a chemical, including studies of chemical disposition, genetic toxicity, immunotoxicity, teratology, reproductive toxicity, carcinogenicity, neurotoxicity, and specific organ toxicity. The NTP encourages nominations of chemicals of human health concern from all sectors of the public, including industry, labor, and the general public. The specific process of nomination, evaluation, and selection of chemicals for testing by the NTP is described. It is a multicomponent system with several evaluations and a public peer review step to assure adequate consideration of all nominated chemicals. The results of NTP studies are all peer reviewed and available to the general public as well as to the scientific community. 相似文献

Substance abuse prevention counseling can be found in two venues: school counseling and student assistance programs (SAPs). School prevention counseling is based on school psychology and guidance counseling. The authors of this article did not find any empirical studies of prevention counseling. Six criteria were used to assess the published research on SAPs: research designs, sampling methods, measures, procedures, analyses, and peer review of results. SAP studies reviewed were placed in one of three levels: Rigorous (N = 3; met all inclusion criteria), Informative (N = 2; met all criteria except peer review), and Evaluative (N = 5; weak design, but explicit in describing methods). The Rigorous Studies found a decrease in substance use or risk factors. The two Informative Studies found a decrease in substance use. The Evaluative Studies demonstrated the prevention of increases in substance use. 相似文献

The traditional assumption that young people are introduced to illegal drugs as a result of peer pressure has been increasingly challenged in recent years with a number of authors arguing that peer selection and individual choice are more important influences. The present paper seeks to further our understanding of this issue by examining the accounts which a sample of pre-teenage children gave of their initial use of drugs. While peer pressure, a desire to conform to the group, and other attempts to influence them were found to be involved in a proportion of the cases, the dominant factors in initial use were personal choice and curiosity. It was also clear that curiosity, external influences and a desire to conform were not mutually exclusive and would often interact as part of a complex dynamic. The paper concludes by discussing the implications of the findings for drugs education. 相似文献

ABSTRACTObjectives: The objective of this study was to analyze the characteristics and costs of exogenous endoscopy-related infections, pseudo-infections, and toxic reactions in the US.Methods: A systematic review of the scientific literature published between 1966 and 2005 was conducted in Medline. Data collection was based on a prospective protocol developed by the authors.Results: The literature review included 70 outbreaks described in 64 scientific articles. Bronchoscopy accounted for half of all reported outbreaks. Inadequate decontamination practices were the leading cause of contamination; equipment malfunction became the second leading cause of contamination during the period 1990–2004. More than 91% of the infections identified could be prevented by health care providers if quality control systems are improved and implemented. The available economic information concerning exogenous endoscope related events is very limited. A model for the analysis of the economic burden of exogenous endoscopy-related events is proposed.Conclusions: Proper decontamination practices, the use of protective sheaths, and the improvement of surveillance systems could reduce the clinical and economic burdens associated with exogenous endoscopy-related events. 相似文献
