Modern methods of searching the medical literature.

OBJECTIVE: To review the methods of electronic retrieval of biomedical journal articles; to demonstrate CD-ROM and online searching techniques; and to compare major biomedical databases. DESIGN: A CD-ROM MEDLINE search was made by a medical practitioner, with the assistance of an experienced librarian. An online MEDLINE/Excerpta Medica search was made by the same medical practitioner after completion of a two-day course in search techniques. The search example covered the period 1983 to 1992, and the topic was "whether steroid use for asthma/airways disease leads to osteoporosis". OUTCOMES: Search duration, article yield and search cost were assessed. RESULTS: The CD-ROM MEDLINE literature search took 60 minutes to find 31 articles (43% of the possible articles). This compared with an online search to the Bibliographic Retrieval Services database in Chicago, which produced the same articles when MEDLINE was searched (but took only 16 minutes) and which also found 47 articles (with an overlap of only seven) when Excerpta Medica was searched. We estimated that the combined MEDLINE and Excerpta Medica search detected 93% of all known relevant articles, based upon an assumed gold standard. CONCLUSIONS: Online searching is a fast and powerful alternative to CD-ROM searching. Formal training is necessary for quick and cheap reference finding. Other benefits such as direct transfer from online searching to your own computer bibliography database make online searching of biomedical databases essential to consider.

Is Canadian cardiac surgeons' management of asymptomatic carotid artery stenosis at coronary artery bypass supported by the literature? A survey and a critical appraisal of the literature.

OBJECTIVE: To document and compare the management of asymptomatic carotid stenosis (ACS) by Canadian cardiac surgeons at coronary artery bypass grafting (CABG) against a critical literature analysis. DESIGN: A multiple choice survey and a structured literature review. DATA SOURCES: Seventy-seven surgeons and 272 publications selected from the English literature between 1980 and 1997. Search terms used were "carotid," "coronary bypass," and "cardiac surgery." STUDY SELECTION: Five natural history studies were identified, and 58 studies were found that had objective documentation of ACS of 50% or more before cardiac surgery, and both operative stroke and mortality data reported for CABG with and without carotid endarterectomy (CEA). DATA EXTRACTION: Natural history and outcome studies were independently rated against published guidelines. Outcome data were independently pooled and compared. Data discrepancy was resolved by consensus. Survey results were tabulated for simple descriptive statistics. DATA SYNTHESIS: No methodologically sound natural history studies were found to document an increased risk of stroke from ACS after CABG. There were no randomized controlled studies to guide treatment recommendations. Pooled data for stroke or death did not support CEA for risk reduction from ACS at CABG (relative risk 0.9, p = 0.5). Ninety-four percent of surgeons believed that the literature is insufficient to support the routine use of CEA to reduce the risk of stroke from ACS after CABG. Despite this, 20% of surgeons advocated CEA for this purpose. CONCLUSION: The management of ACS at CABG by the majority of Canadian cardiac surgeons is consistent with the results of the literature review; however, significant management variation exists.

[Computer-assisted ENT medical literature search and literature management--a report of experiences].

The increasing number of medical articles calls for a computer-aided system for literature database programs, literature retrieval and bibliography systems. We report an assessment of a dedicated modem line to DIMDI of Cologne (an institute offering a variety of biomedical, psychological and other literature databases), Medline on Silverplatter, Current Contents on disk and the Papyrus bibliography system. The databases with retrieval software are installed on a IBM-compatible PC (386 with an 80MB hard disc) and 4 CD-ROM players. Medline contains bibliographic citations and abstracts of biomedical literature; Current Contents on disk with its weekly update provides citations of articles published very recently; and the Papyrus bibliography system maintains a permanent collection of reference citations. When linked to a word processor, Papyrus can automatically read the manuscript, create a bibliography and produce a new copy of the manuscript in which the citations have been appropriately edited, and the references can be printed in any desired format. Although not without drawbacks, the configuration described here proved to be a valuable, time-saving tool to access citations precisely.

Searching the literature creatively: updating your skills in reviewing the literature.

Reviewing the literature is not only an essential aspect of research, it can be a creative process. Computerized searches decrease the hours that searches formerly took and allow the researcher to link concepts in ways that were previously difficult to do. Be consistent with your approach to reviewing the literature and your reward will be a comprehensive overview of the extant literature--an excellent start to validating your research project.

Index to Dental Literature and MEDLINE: a guide to searching the dental literature.

The Index to Dental Literature is generated from the MEDLARS data tapes. The dental file, a subset of MEDLARs, is available for online searching. One of the major problems encountered when searching for dental literature in the predominately medical file is the specificity of the dental vocabulary. Six suggestions are given to help the user find the closest MeSH equivalent for the dental concept. Examples are provided to illustrate retrospective searching of the BACKfiles and the uses of journal titles lists, dental terms, subheadings, Text Words, and pre-explosions when searching MEDLINE for dental and related literature.

A comparison of drug literature coverage by Index Medicus and Drug Literature Index.

We compared Index Medicus and Drug Literature Index during a search concerning the toxicity of eight drugs used in treating tropical diseases. Indexes covering the years 1969, 1970, and 1971 were searched. Index Medicus produced 198 citations and Drug Literature Index 309. There were seventy citations that appeared in both indexes, a duplication of 16%. Highest percentage of duplication for any one drug was 38.9%. We concluded that Index Medicus and Drug Literature Index provide complementary coverage in the area of drug toxicity and that, therefore, both tools should be consulted in searches of this nature.

[Scotchbond from 1983 to 1992. The history of a market setter reflected in the literature. A review of the literature].

In this critical literature review 140 [correction of 136] publications dealing with Scotchbond were chronologically compiled since 1983 when Scotchbond was introduced to the dental market. The publications dealing with dentinal bonding were analyzed. Critical statements were predominant in the in-vivo- as well as in the in-vitro-studies. The literature reviewed for a period of ten years clearly demonstrated that the expectations created by the manufacturer and some initial studies concerning dentinal bonding did not become true. Long before private practitioners realized that Scotchbond didn't live up to the standards promised by the manufacturer, independent scientists had doubted the efficiency of the product. The conflict between market orientated and objective information for the private practitioners becomes obvious in this literature review.

How to keep up with the medical literature: V. Access by personal computer to the medical literature.

Access to the medical literature through personal computers is now readily available and can greatly reduce logistical barriers to using recently published journal articles to support clinical decisions. In this article, we describe many of the options available to clinicians who wish to do their own computer searching of MEDLINE, the largest of the electronic services for the biomedical literature. The "bare bones" computer equipment needed includes a terminal or personal computer, a modern and telephone line, and a printer. Access to MEDLINE is then gained through subscribing to any of a burgeoning number of database vendors. A comparison of 17 permutations and combinations of software and vendors shows that the software and vendors vary substantially in efficiency, cost, and ease of use. Direct subscription to MEDLINE is least expensive, PaperChase is the simplest service to use, and Colleague and Medis provide both MEDLINE access plus full-text journals online. Basic search techniques are illustrated for three clinical problems.

International exchange of scientific literature by U.S. academic health sciences libraries: a literature review and survey of current activities.

This paper reports results of a literature review and survey of current international exchange activities in 124 academic health sciences libraries in the United States. It describes the extent to which those libraries engage in exchange programs, the kinds of material sent and received, and the common problems in establishing and maintaining exchange relationships. Preferences of the respondents for future exchange programs are identified and recommendations for enhancing their value are made. The work reported is being used by the Medical Library Association Ad Hoc Committee on the International Exchange and Redistribution of Library Materials to develop a more workable and effective mechanism for continuing the international exchange of scientific literature and for facilitating the dissemination of scientific information to national and international network users.

Intracranial meningiomas associated with glial tumours: a review based on 54 selected literature cases from the literature and 3 additional personal cases.

The simultaneous occurrence of meningioma and glioma is extremely rare. Three new cases and 54 adequately described in the literature are analyzed. Clinical diagnosis may be difficult due to discrepancy between clinical and radiological findings. Unexpected clinical deterioration following removal of a tumour and relapse simulating recurrence may occur. The introduction of CT technology does not seem to have offered the expected contribution to the early diagnosis of these coincidental lesions, at least before the introduction of the newer generation scanners or MRI. While removal of both tumours in one session yielded the best results, surgery for the sole glioma appeared to be associated with an unacceptably high mortality. Although several aetiopathogenetic hypotheses have been suggested for explaining this curious association, coincidental meningioma and glioma are most likely to be different primary brain tumours occurring randomly in the same individual.

Epidemiology and the veterinary oncologist--evaluation and critical appraisal of the scientific oncology literature: how to read the clinical literature.

Even in the most specialized areas of veterinary medicine, few clinicians or researchers can keep up with the volumes of scientific literature currently published. Faced with this onslaught, most clinicians would benefit from a systematic approach for selecting articles to read and evaluating their scientific merit.

How to keep up with the medical literature: IV. Using the literature to solve clinical problems.

Ideally, searches for published articles to solve clinical problems should lead to the best evidence on a given topic quickly and at reasonable expense. This goal can be achieved with modern information skills, sources, and services. In this article, we describe and compare various means, from textbooks to computers, that provide access to information of potential value in addressing clinical problems as they arise. Using the problem of understanding and controlling the risk for the acquired immunodeficiency syndrome among personnel of a community hospital, we examined the following sources for their utility in locating journal literature: general and specialty medical texts, personal reprint collections, expert clinicians, recent journal issues, library textbook collections, the Index Medicus "Bibliography of Reviews" and subject index, and MEDLINE computer searching. For this problem, Index Medicus and MEDLINE were the best sources of up-to-date articles, but MEDLINE was three times as fast.
