Lyme disease surveillance in the United States: Looking for ways to cut the Gordian knot.

Current surveillance methods have been useful to document geographic expansion of Lyme disease in the United States and to monitor the increasing incidence of this major public health problem. Nevertheless, these approaches are resource-intensive, generate results that are difficult to compare across jurisdictions, and measure less than the total burden of disease. By adopting more efficient methods, resources could be diverted instead to education of at-risk populations and new approaches to prevention. In this special issue of Zoonoses and Public Health, seven articles are presented that either evaluate traditional Lyme disease surveillance methods or explore alternatives that have the potential to be less costly, more reliable, and sustainable. Twenty-five years have passed since Lyme disease became a notifiable condition - it is time to reevaluate the purpose and goals of national surveillance.

Pet ownership increases human risk of encountering ticks.

We examined whether pet ownership increased the risk for tick encounters and tickborne disease among residents of three Lyme disease-endemic states as a nested cohort within a randomized controlled trial. Information about pet ownership, use of tick control for pets, property characteristics, tick encounters and human tickborne disease were captured through surveys, and associations were assessed using univariate and multivariable analyses. Pet-owning households had 1.83 times the risk (95% CI = 1.53, 2.20) of finding ticks crawling on and 1.49 times the risk (95% CI = 1.20, 1.84) of finding ticks attached to household members compared to households without pets. This large evaluation of pet ownership, human tick encounters and tickborne diseases shows that pet owners, whether of cats or dogs, are at increased risk of encountering ticks and suggests that pet owners are at an increased risk of developing tickborne disease. Pet owners should be made aware of this risk and be reminded to conduct daily tick checks of all household members, including the pets, and to consult their veterinarian regarding effective tick control products.

Assessing diagnostic coding practices among a sample of healthcare facilities in Lyme disease endemic areas: Maryland and New York - A Brief Report.

The value of using diagnostic codes in Lyme disease (LD) surveillance in highly endemic states has not been well studied. Surveys of healthcare facilities in Maryland (MD) and New York (NY) regarding coding practices were conducted to evaluate the feasibility of using diagnostic codes as a potential method for LD surveillance. Most respondents indicated that their practice utilized electronic medical records (53%) and processed medical/billing claims electronically (74%). Most facilities were able to search office visits associated with specific ICD-9-CM and CPT codes (74% and 73%, respectively); no discernible differences existed between the healthcare facilities in both states. These codes were most commonly assigned by the practitioner (82%), and approximately 70% of respondents indicated that these codes were later validated by administrative staff. These results provide evidence for the possibility of using diagnostic codes in LD surveillance. However, the utility of these codes as an alternative to traditional LD surveillance requires further evaluation.

Mapping the literature of dental assisting.

The purpose of this study was to identify core journals and the databases that provide access to these journals for the field of dental assisting. This study was completed as a part of the Medical Library Association (MLA) Nursing and Allied Health Resources Section's project to map the literature of allied health. There were three original journals selected for analysis using the prescribed methodology, Dental Assistant, the journal of the American Dental Assistants Association; Journal of the CDAA, the journal of the Canadian Dental Assistants' Association; and Dental Teamwork, published by the American Dental Association. Dental Teamwork ceased publication in December 1996; however, it was considered a necessary part of the analysis due to its extensive coverage of dental assisting as well as its numerous scientific articles with references. In Dental Assistant, there were 16 source articles, containing 206 citations. In Dental Teamwork, there were 31 source articles with 308 citations. In Journal of the CDAA, there were only 3 source articles with 14 citations. Bradford's Law of Scattering was applied to the journal citations. Four databases, MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, EMBASE/Excerpta Medica, and HEALTH were analyzed for their coverage of these cited journals. This study may encourage the dental assisting profession to take a close look at its existing journals and to consider enhancing the content of these journals or the publication of additional journals in the field. Dental assistants of today need substantive literature that deals with all aspects of their chosen profession in order to meet the challenges of providing dental health care in the future.

End user searching at Indiana University School of Dentistry: tailoring a program for a specific user group.

While many librarians support the concept of end user searching, they fear that large costs will be incurred with the introduction of such a program. This article describes an economical end user training program which was developed at the Indiana University School of Dentistry. End user training at IUSD is fully self-supporting and has been tailored to meet the needs of a very specialized user group.

Hospital libraries in West Germany: an overview of reference services.

This article presents a study on reference services in German hospital libraries. Information for the study was obtained through personal interviews conducted at four libraries in Stuttgart, West Germany in August 1985. A detailed questionnaire covering services provided, staff training, and use of computers was used during the interviews. While reference services are minimal at the libraries in the study, the commitment to patient library services in Germany is exceptional.

Early dental journalism: a mirror of the development of dentistry as a profession.

The rise of dentistry from a mechanical trade to a profession has often been attributed to the so-called "triumvirate" of organization, education, and journal literature. This essay focuses on one part of the triumvirate, examining the role of journals in the growth of dentistry as a profession, from the appearance of the first journal in 1839 to the publication of the Index to Dental Literature in 1921. Rather than discussing the history of individual titles, it identifies some of the broader issues and problems that confronted early dental journalism. The evolution of dental journals from trade house publications to independent scientific literature mirrored the movement toward professional status in dentistry during the late 19th and early 20th centuries.
