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.

Preservation of environmental characteristics as witnessed in classic and modern literature: the case of Greece.

The literature provides interesting evidence regarding some of the environmental characteristics of Greece during the classic era, while in recent times, the environmental consequences of urban development are impressed in the work of modern Greek writers. The present paper investigates references regarding these environmental characteristics together with their preservation in time, with the aid of resources from literature.

The distaff and the staff: stereotypes and archetypes of the older woman in representative modern literature.

Belles-lettres, dealing with what it means to be human, serve to expose stereotypes, strip them away, and reveal the truth behind the misconceptions, often in terms of archetypes. An all-too-common subject of stereotyping is the aging of women. Much modern fiction and poetry cogently exposes such demeaning stereotypes. References to twenty-five representative poems and nine works of fiction by thirty-five modern authors (American, British, Australian, French) demonstrate that the elderly woman often survives with dignity, even nobility, in a society often insensitive to her plight, that she often ages with grace, retaining her independence, fortitude, and passion for life.

[Several aspects of modern literature research].

This article reviews today's methods of searching the literature, especially the electronic ones. There are 2 main methods of searching: CD-ROM- and online searching. 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.

[Saliva: clinical and diagnostic usefulness. Review of the literature].

Modern clinical pathology is mainly based on the analysis of blood samples, carried out through more and more sophisticated techniques. Being the blood test an invasive technique, it certainly reduces the possibility of carrying out blood analysis, especially in patients such as children, old people, handicapped people and every person who needs continuous biochemical or pharmacological monitoring. In these cases it is very important to find other body fluids that can be easily obtained and that can offer the same reliable data as blood. Due to some of its characteristics, sometime saliva may be a good alternative to venous blood, as it presents the same features of plasma or urine. The chemical analysis of saliva provides some information that are useful for metabolic, inflammatory, neoplastic and genetic diseases; furthermore radioimmunological dosages allow to assess small concentrations of active substances. On the basis of an accurate review of literature, the aim of this study is to analyse the importance of saliva in diagnosing and monitoring certain systemic diseases, the utilization of saliva in hormonal and pharmacological dosages and the use of saliva in some epidemiological studies. Finally, it is emphasized that saliva in monitoring may help to manage several clinical conditions.

Wavelets and imaging informatics: a review of the literature.

Modern medicine is a field that has been revolutionized by the emergence of computer and imaging technology. It is increasingly difficult, however, to manage the ever-growing enormous amount of medical imaging information available in digital formats. Numerous techniques have been developed to make the imaging information more easily accessible and to perform analysis automatically. Among these techniques, wavelet transforms have proven prominently useful not only for biomedical imaging but also for signal and image processing in general. Wavelet transforms decompose a signal into frequency bands, the width of which are determined by a dyadic scheme. This particular way of dividing frequency bands matches the statistical properties of most images very well. During the past decade, there has been active research in applying wavelets to various aspects of imaging informatics, including compression, enhancements, analysis, classification, and retrieval. This review represents a survey of the most significant practical and theoretical advances in the field of wavelet-based imaging informatics.

The extraction of useful information from the biomedical literature.

Modern information technology provides the biomedical professional with powerful tools and processes for extracting useful information from large volumes of text. Presently, little use is made of the full capabilities of these tools to supplement research and teaching. This article gives an overview of these tools and processes, and shows the diversity of ways they can be applied to enhance the capabilities of biomedical professionals. The article defines information technology terms, presents the requirements for extracting high-quality information, describes some available techniques for extracting information, and summarizes myriad information-extraction applications. While the biomedical researcher or teacher can gain substantial benefits by using effective information-extraction techniques, substantial time and effort and technical expertise are required to generate a credible high-quality product, that is, the information needed.
