目的探讨绝经后子宫内膜厚度及绝经时间对内膜癌的预测价值。方法127例绝经后阴道出血患者内膜活检术前采用经阴道超声测量子宫内膜厚度,比较良、恶性组患者的发病年龄、平均内膜厚度,并对子宫内膜癌与内膜厚度及绝经时间的关系进行分析。结果127例患者(良性病变115例、内膜癌12例)经阴道超声测量,内膜癌组的平均内膜厚度(14.3±7.3)mm大于内膜良性病变组(7.0±4.4)mm(P<0.01)。其中内膜厚度≥10mm者内膜癌9例(9/45);内膜厚度≤5mm者无一例内膜癌。绝经后1~5年阴道出血者内膜厚度≤8mm、绝经5~15年阴道出血者内膜厚度≤6mm、绝经15年以上阴道出血内膜厚度≤5mm者发生内膜癌的可能性较小。结论内膜厚度及绝经时间与内膜癌的发生有相关性,随着绝经时间及内膜厚度的增加其发病率也增加。超声测量内膜厚度可减少绝经后阴道出血患者的内膜活检率。  相似文献

Objective: To identify patterns of nonfatal and fatal penetrating trauma among children and adults in New Mexico using ED and medical examiner data.
Methods: The authors retrospectively sampled in 5-year intervals all victims of penetrating trauma who presented to either the state Level-1 trauma center or the state medical examiner from a 16-year period (1978–1993). Rates of nonfatal and fatal firearm and stabbing injury were compared for children and adults.
Results: Rates of nonfatal injury were similar (firearm, 34.3 per 100,000 person-years; stabbing, 35.1). However, rates of fatal injury were significantly different (firearm, 21.9; stabbing, 2.7; relative risk: 8.2; 95% confidence interval: 5.4, 12.5). From 1978 to 1993, nonfatal injury rates increased for children (p = 0.0043) and adults (p < 0.0001), while fatal penetrating injury remained constant. The increase in nonfatal injury in children resulted from increased firearm injury rates. In adults, both stabbing and firearm nonfatal injury rates increased.
Conclusions: Nonfatal injury data suggest that nonfatal violence has increased; fatal injury data suggest that violent death rates have remained constant. Injury patterns vary by age, mechanism of trauma, and data source. These results suggest that ED and medical examiner data differ and that both are needed to guide injury prevention programs.  相似文献

Three supplementary perspectives are presented arguing that interprofessional collaboration is both necessary and desirable. Nonetheless, there are often too many serious intra-professional barriers and obstacles to interprofessional collaboration to make it successful. Some of these barriers, it is argued and illustrated, are found in the multiple ways in which professional identity is tacitly acquired and embodied in the practitioners' habitual, everyday practice. The paper then explores ways in which reflection, especially Second order reflection, can help to elucidate and overcome these obstacles, as well as increasing professional adaptability and competence.  相似文献

The prospects for the control of neglected tropical diseases, including soil-transmitted helminthiasis, shistosomiasis, lymphatic filariasis, onchocerciasis and trachoma, through mass drug administration, are exemplified by the elimination of the trachoma as a public-health problem in Morocco. In spite of this and other striking successes, mass drug administration programs are faced with major challenges resulting from suboptimal coverage and lack of efficacy. At current suboptimal coverage rates, programs may need prolongation for an extended period, increasing costs and undermining sustainability. Community participation through health education and information appears to be crucial to improve coverage and to achieve sustainability. Implementation of complementary measures, such as vector control, improved hygiene and environmental sanitation, are important to further control transmission and to prevent re-emergence of the infection and, again, may only be achieved effectively through community-based initiatives. To reduce costs and to relieve pressure on the health system, combining neglected tropical disease programs in areas where diseases coexist and integration with existing control programs for malaria, tuberculosis and HIV/AIDS is advocated. The risk of developing drug resistance is of particular concern in view of the lack of alternative drugs, and reduced treatment efficacy due to emerging resistance is evident for the soil-transmitted helminths and onchocerciasis. Given the risk for the development of drug resistance and the need for a high degree of participation, close attention should be paid to the monitoring of the coverage and efficacy of the different program components.  相似文献

The outcome of bacterial meningitis critically depends on the rapid initiation of bactericidal antibiotic therapy and adequate management of septic shock. In community-acquired meningitis, the choice of an optimum initial empirical antibiotic regimen depends on the regional resistance patterns. Pathogens resistant to antibacterials prevail in nosocomial bacterial meningitis. Dexamethasone is recommended as adjunctive therapy for community-acquired meningitis in developed countries. In comatose patients, aggressive measures to lower intracranial pressure <20 mmHg (in particular, external ventriculostomy, osmotherapy and temporary hyperventilation) were effective in a case–control study. Although many experimental approaches were protective in animal models, none of them has been proven effective in patients. Antibiotics, which are bactericidal but do not lyse bacteria, and inhibitors of matrix metalloproteinases or complement factor C5 appear the most promising therapeutic options. At present, vaccination is the most efficient method to reduce disease burden. Palmitoylethanolamide appears promising to enhance the resistance of the brain to infections.  相似文献

Background: Hip fracture is a common injury, with an incidence rate of > 250,000 per year in the United States. Diagnosis is particularly important due to the high dependence on the integrity of the hip in the daily life of most people. Objectives: In this article we review the literature focused on hip fracture detection and discuss advantages and limitations of each major imaging modality. Discussion: Plain radiographs are usually sufficient for diagnosis as they are at least 90% sensitive for hip fracture. However, in the 3–4% of Emergency Department (ED) patients having hip X-ray studies who harbor an occult hip fracture, the Emergency Physician must choose among several methods, each with intrinsic limitations, for further evaluation. These methods include computed tomography, scintigraphy, and magnetic resonance imaging. Conclusion: We present an evidence-based algorithm for the evaluation of a patient suspected to have an occult hip fracture in the ED. Also outlined are future directions for research to distinguish more effective techniques for identifying occult hip fractures.  相似文献

ABSTRACT

The Cochrane Library of Systematic Reviews is published quarterly as a DVD but monthly online. The April 2012 issue (second DVD for 2012) contains 5045 complete reviews, 2182 protocols for reviews in production, and 17,084 short summaries of systematic reviews published in the general medical literature. In addition, there are citations of 674,000 randomized controlled trials, and 15,400 cited papers in the Cochrane methodology register. The health technology assessment database contains just over 11,000 citations. One hundred and seventeen new reviews have been published in the last 3 months of which 12 have potential relevance for practitioners in pain and palliative medicine. The impact factor of the Cochrane Library stands at 6.186. Readers are encouraged to access the full report for any articles of interest as only a brief commentary is provided.  相似文献

When I first got the invitation to join a medical delegation going to Moldova, I thought for a moment that our destination was the fictional country in the old Marx Brothers movie Duck Soup. On further checking, it turns out that entertaining place was called Freedonia. I now know that Moldova is indeed a real country, bordered on the west by Romania and on the other three sides by the Ukraine. It is a proud country, rich with traditions, and its people are warm, giving, eager to learn ways to improve their healthcare system, and deeply appreciative of our attempts to help them in the task.  相似文献

Predictors of patient wishes and influence of family and clinicians are discussed. Research findings on patient decision-making relating to preferences in end-of-life care are described. Advance directives and durable powers of attorney are defined and differentiated. Most patients have not participated in advance care planning and the need for more effective planning is documented. Appropriate times for discussions of such planning are described. Scenarios discussed include terminal cancer, chronic obstructive pulmonary disease, AIDS, stroke, and dementia. Patient satisfaction is discussed, as is a structured process for discussions about patient preferences. Results of patient responses to hypothetical scenarios are described. Invasiveness of interventions, prognosis and other factors that favor or discourage patient preferences for treatment are discussed. Findings resulting from research funded by the Agency for Healthcare Research and Quality (AHRQ) are discussed. This research can help providers offer end-of-life care based on preferences held by the majority of patients under similar circumstances.  相似文献

The Cochrane Library of Systematic Reviewsis published quarterly. Issue one for 2004 of the library was published in February 2004. This issue contains 3,329 reviews and protocols of which 1,921 are fully published reviews. The trials database now stands at over 400,000 records with an additional 4,427 one-page summaries of non-Cochrane reviews in the NHS database of reviews of effectiveness (DARE). This version of the library contains the results of an extensive search for RCTs on EMBASE. The latest library contains 84 new reviews, seven are considered relevant to practitioners in pain and palliative care. References are published in the same format as the citation for Cochrane reviews.  相似文献
