目的:采用循证医学Meta分析方法评价细胞周期蛋白D1(Cyclin D1, CCND1)基因多态性与口腔癌易感性的关联。方法:计算机检索PubMed、CBM、万方、维普、CNKI等中英文数据库,检索范围从建库至2013年7月1日,全面收集相关文献数据并计算优势比(OR)及95%置信区间(CI)以评价关联性。结果:本Meta分析共计纳入10项病例对照研究,包括1622例口腔癌患者及1859例健康对照人群。Meta分析的结果表明:CCND1 G870A基因多态性与口腔癌发病风险增加显著相关(A vs. G: OR=1.23, 95%CI: 1.02~1.49, P=0.033; AA+AG vs. GG:OR=1.39, 95%CI: 1.03~1.87, P=0.031; AA vs. AG+GG: OR=1.32, 95%CI:1.13~1.55,P=0.001; AA vs.GG:OR=1.47,95%CI:1.00~2.16, P=0.049; AA vs. AG: OR=1.22, 95%CI: 1.03~1.44, P=0.020)。亚组分析的结果进一步表明:CCND1 G870A基因多态性与口腔癌发病风险的关联性在亚洲人群和吸烟人群中尤为显著,但在高加索人群和非吸烟人群中并不显著。结论:本文提供的证据表明:CCND1 G870A基因多态性与口腔癌易感性显著相关,这一关联性在亚洲人群与吸烟人群中尤为显著。然而,CCND1 G870A基因多态性与口腔癌易感性之间的关联性,有待更大样本规模的病例对照研究加以证实。 相似文献

目的:探讨鼠双微体基因2(MDM2)SNP309多态性与口腔癌风险的关系。方法:检索文献并按要求提取相关信息,纳入MDM2 SNP309与口腔癌风险的病例-对照研究,对研究结果进行Meta分析。结果:共纳入5个病例-对照研究,包括1369例口腔癌患者和2167例对照。 Meta分析结果显示:与纯合子基因型个体相比较,杂合子基因型个体与口腔癌风险的降低存在显著关联性(TG vs. TT:OR=0.81,95%CI,0.68~0.96,P=0.02),然而纯合子基因型个体与口腔癌风险无明显相关性。在显性遗传模式中(TG+GG vs. TT)口腔癌风险降低具有统计学意义(OR=0.82,95%CI,0.69~0.97,P=0.02),而在隐性遗传模式中却无统计学意义。纳入研究结果间不存在异质性,且未发现显著的发表偏倚。结论:MDM2基因SNP309多态性与口腔癌易感性相关,可能是口腔癌易感的保护性因素。 相似文献

Objective
Neglect of a child's oral health can lead to pain, poor growth and impaired quality of life. In populations where there is a high prevalence of dental caries, the determination of which children are experiencing dental neglect is challenging. This systematic review aims to identify the features of oral neglect in children.Methods
Fifteen databases spanning 1947–2012 were searched; these were supplemented by hand searching of 4 specialist journals, 5 websites and references of full texts. Included: studies of children 0–18 years with confirmed oral neglect undergoing a standardised dental examination; excluded: physical/sexual abuse. All relevant studies underwent two independent reviews (+/− 3rd review) using standardised critical appraisal.Results
Of 3863 potential studies screened, 83 studies were reviewed and 9 included (representing 1595 children). Features included: failure or delay in seeking dental treatment; failure to comply with/complete treatment; failure to provide basic oral care; co-existent adverse impact on the child e.g. pain and swelling. Two studies developed and implemented ‘dental neglect’ screening tools with success. The importance of Quality of Life tools to identify impact of neglected dental care are also highlighted.Conclusions
A small body of literature addresses this topic, using varying definitions of neglect, and standards of oral examination. While failure/delay in seeking care with adverse dental consequences were highlighted, differentiating dental caries from dental neglect is difficult, and there is a paucity of data on precise clinical features to aid in this distinction.Clinical significance
Diagnosing dental neglect can be challenging, influencing a reluctance to report cases. Published evidence does exist to support these referrals when conditions as above are described, although further quality case control studies defining distinguishing patterns of dental caries would be welcome. 相似文献14.

The aims of this paper are three-fold: (1) to summarize the current epidemiological data on oral cancer in Libya as reported in the published literature and as compared to other national oral cancer rates in the region; (2) to present both the history of the early development, and future goals, of population-based oral cancer tumor registries in Libya as they partner with the more established regional and international population-based cancer tumor registries; and, (3) to offer recommendations that will likely be required in the near future if these nascent, population-based Libyan oral cancer registries are to establish themselves as on-going registries for describing the oral cancer disease patterns and risk factors in Libya as well as for prevention and treatment. This comprehensive literature review revealed that the current baseline incidence of oral cancer in Libya is similar to those of other North Africa countries and China, but is relatively low compared to the United Kingdom, the United States, and India. The recently established Libyan National Cancer Registry Program, initiated in 2007, while envisioning five cooperating regional cancer registries, continues to operate at a relatively suboptimal level. Lack of adequate levels of national funding continue to plague its development…and the accompanying quality of service that could be provided to the Libyan people. 相似文献

Oral cancer is referred to specialists by both general practitioners (GPs) and dentists, with varying proportions reported in different studies. However, some have noted that dentists more commonly refer oral cancer in the absence of patient-perceived symptoms and may refer at an earlier stage. Unfortunately, approximately half the UK adult population do not receive regular dental care. We have conducted a systematic review of studies that compare GPs and dentists in the referral of oral cancer and have focused on three aspects: the proportion of diagnosed oral cancers, stage on presentation, and delay. Searches of the databases Medline, Embase, Scopus, Google Scholar, Web of Science, and CINAHL, together with additional searches of reference lists, authors, and conference proceedings, found 22 studies from 10 countries, which included a total of 4953 oral cancers. The percentage of medical referrals ranged from 13% to 86%; dental referrals ranged from 15% to 80%. Random-effects meta-analysis indicated a combined relative risk of medical referral to dental referral of 1.36 (95% CI: 0.99 to 1.86). For UK-based studies, the relative risk was also 1.36 (95% CI: 1.05 to 1.76). There was considerable heterogeneity for all studies and for a subgroup of UK studies: I296.4% (95% CI 95.4 to 97.1) and 81.0% (95% CI 63.3 to 90.1), respectively. Several studies showed a lower stage for dentally-referred cancers; the combined risk for dentists and GPs referring early (stages 1 and 2) disease was 1.37 (95% CI: 1.17 to 1.60), and one cause may be the much higher number of cases referred by dentists in the absence of symptoms. No studies showed a significant difference in delay. Oral cancer is referred by both GPs and dentists, typically about 50% and 40%, respectively, although there is a wide range, probably depending on local circumstances. Both groups require skills in oral examination, recognition of lesions, and knowledge of the risk factors. Effectively, regular dental attenders are a select group that is regularly screened for oral cancer, and it is likely that screening is not delivered to those with the highest risk. We suggest that further work is required on how to access high-risk individuals both for possible screening and preventive interventions. 相似文献

This systematic review aims to compare different fat-grafting techniques for cleft lip and palate repair. A search was conducted in PubMed, Embase, Cochrane Library, gray literature and reference lists of selected articles. A total of 25 articles were included, 12 on closure of palatal fistula and 13 on cleft lip repair. The rate of complete resolution of palatal fistula ranged from 88.6% to 100% in studies with no control group, whereas in comparative studies patients receiving a fat graft showed better outcomes than those not receiving a graft. Evidence suggests that fat grafting can be indicated for the primary and secondary repair of cleft palate, with good results. The use of dermis-fat grafts in lip repair was associated with gains in surface area (11.5%), vertical height (18.5%–27.11%), and lip projection (20%). Fat infiltration was associated with increased lip volume (6.5%), vermilion show (31.68% ± 24.03%), and lip projection (46.71% ± 31.3%). The available literature suggests that fat grafting is a promising autogenous option for palate and fistula repair and for improvement of lip projection and scar aesthetics in patients with cleft. However, to develop a guideline, further studies are needed to confirm whether one technique is superior to the other. 相似文献
