A quiz becomes a multidirectional dialogue with Web-based instructional tools for an anatomical pathology rotation.

Senior veterinary students in the Iowa State University College of Veterinary Medicine (ISU CVM) participate in clinical rotations, among them a two-week necropsy rotation. The students have access to the rotation syllabus on the ISU CVM intranet site. To promote rapid comprehension of necropsy protocol, students completed a pre-exam on the syllabus. This exercise evolved from a paper quiz to an online pre-exam, using course management software to improve use of class time, increase feedback, and shift the focus to acquisition of knowledge. The students were encouraged to work collaboratively on the pre-exam and could make repeated attempts. We predicted that professional students would make multiple attempts at the pre-exam until the desired score was attained. This exercise achieves multiple goals. First, the exam encourages early review of necropsy protocol. Second, use of WebCT allows for instant, automatic, and consistent feedback from the instructor, reducing redundancy while improving the quality of communication between student and instructor and thus using faculty time more efficiently. The instructor can quickly identify and rectify common misunderstandings through this interface. Third, by allowing discussion and repeated attempts, we can ensure that there is less pressure associated with the exam. Statistical analysis of the students' performance supports the prediction that students would repeat the exam until the desired score was achieved. Subjectively, as a result of implementation of an online pre-exam, the instructor has observed students to be more engaged with the material at an earlier point in the rotation.

Virchow's contributions to veterinary medicine: celebrated then, forgotten now.

In 1858, Rudolf Virchow, the professor of pathology in Berlin University, published the book "Cellular Pathology". A compendium of his lectures to physicians and medical students, he introduced the use of microscopy for the study of human diseases. To an astonishing extent Rudolf Virchow was helpful to the disciplines of veterinary medicine (and veterinary pathology). Considered a scientific genius in several disciplines, this essay deals exclusively with the devotion of Virchow, a scholarly physician, to the profession of veterinary medicine. He respected veterinary research, supported governmental veterinary education, and provided a role model for the veterinarians who were drafting control legislation of contagious diseases in livestock. Repeatedly, he responded in help when seemingly irretrievable problems arose. Examples of Virchow's activities in the realms of veterinary medicine and pathology are marshalled here to shed light on this pioneer "veterinary pathologist". In celebration of 50 years of the American College of Veterinary Pathologists in 1999, it is timely to remember that Rudolf Virchow, the father of cellular pathology, also fathered veterinary pathology, whose offsprings in Canada and the U.S.A. (Osler, Clement, Williams, Olafson, Jones) had enabled them to form and foster the A.C.V.P.

Clinical pathology testing recommendations for nonclinical toxicity and safety studies. AACC-DACC/ASVCP Joint Task Force.

Clinical pathology testing in nonclinical toxicity and safety studies is an important part of safety assessment. In recent years, clinical laboratory testing has rapidly expanded and improved. Some government regulatory agencies provide guidelines for clinical pathology testing in nonclinical toxicity and safety studies. To improve these testing guidelines and the resultant safety assessments, the American Association for Clinical Chemistry's Division of Animal Clinical Chemistry and the American Society for Veterinary Clinical Pathology formed a joint committee to provide expert recommendations for clinical pathology testing of laboratory species involved in subchronic and chronic nonclinical toxicity and safety studies. These recommendations include technical recommendations on blood collection techniques and hematology, serum chemistry, and urinalysis tests.

Comparison of two automated spectrophotometric methods for ceruloplasmin measurement in pigs.

Ceruloplasmin (Cp) determination could provide an objective measure of the health status of an animal and could be used as marker of animal health and welfare (Skinner, 2001) (Skinner, J. G., 2001. Special report. International standardization of acute phase proteins. Veterinary Clinical Pathology 30, 2-7.) but only manual methods have been reported to determine Cp concentrations in pigs (McCosker, 1961; Toussaint et al., 1995; Eckersall et al., 1996) (McCosker, P. J., 1961. Paraphenylenediamine oxidase activity and copper-levels in mammalian plasmas. Nature. 190, 887-889; Toussaint, M. J. M., Van Ederen, A. M., Gruys, E., 1995. Implication of clinical pathology in assessment of animal health and in animal production and meat inspection. Comparative Haematology International 5, 149-157; Eckersall, P. D., Saini, P. K., McComb, C., 1996. The acute phase response of acid soluble glycoprotein, alpha(1)-acid glycoprotein, ceruloplasmin, haptoglobin and C-reactive protein, in the pig. Veterinary Immunology and Immunopathology 51, 377-385). In the present study two automated methods based on the use of two different substrates for the determination of serum ceruloplasmin in pigs were developed, evaluated and compared. Both methods showed a good precision and detection limits, with no signs of inaccuracy and could be applied to biochemical autoanalyzers usually found in clinical laboratories using only minimal amounts of serum. Additionally the behaviour of Cp in experimental and clinical situations was studied showing an increase of around two fold after turpentine administration and significantly higher values in cases of pigs with inflammatory conditions when compared with healthy pigs.

Mechanism-based diagnostic reasoning: thoughts on teaching introductory clinical pathology.

Teaching introductory clinical pathology to veterinary students is a challenging endeavor that requires a shift in learning strategies from rote memorization to diagnostic reasoning. Educational research has identified discrete cognitive stages required to achieve the automated, unconscious thinking process used by experts. Building on this knowledge, we developed a case-based approach to clinical pathology instruction that actively engages students in the learning process and links performance with positive reward. Simulated cases provide context and create a structure, or "schema", which enhances the learning process by enabling students to synthesize facts and link them with their causal mechanism to reach a defensible diagnostic conclusion. Web-based tools, including the "Problem List Generator" and tutorials, have been developed to facilitate this process. Through the collaborative Biomedical Informatics Research Group, we are working to further develop and evaluate Web-based instructional tools and new educational methods, to clarify the diagnostic reasoning processes used by experienced clinical pathologists, and, ultimately, to better educate our future students to be effective diagnosticians.

In situ hybridization with riboprobes: an overview for veterinary pathologists.

In situ hybridization using nonradioactively-labeled RNA probes is a technique that combines understanding of basic molecular biology and histopathologic interpretation. Recombinant or PCR technology can be used to produce probes that hybridize with a wide variety of cellular genes and infectious agents. Hybridization conditions can be optimized for each probe/target combination.
