A modular numerical model of the cardiovascular system has been developed to reproduce the most important circulatory phenomena in terms of pressure and volume relationships. It is an easy tool to use, designed to be used with a friendly approach on any IBM or compatible personal computer: it offers a wide selection of graphical and numerical outputs and can be rearranged easily for a particular experiment. A set of subroutines related to different circulatory phenomena has been developed; they can be assembled easily together and communicate with each other by two variables. A full description of the existing subroutines is presented in this paper with three different application examples resulting from the rearrangement of the existing software modules: the first concerns the behaviour of the natural ventricle model itself and can be regarded as a ventricle stand-alone characterization test in terms of preload and afterload sensitivities, the second is related to the use of a pneumatic ventricle instead of the model of the natural ventricle, and the third is a full model of the cardiocirculatory system.

A case-based program called ATLes (Adaptive Teaching and Learning Environments) was designed for use in a systemic pathology course and implemented over a four-year period. Second-year veterinary students working in small collaborative learning groups used the program prior to their weekly pathology laboratory. The goals of ATLes were to better address specific learning objectives in the course (notably the appreciation of pathophysiology), to solve previously identified problems associated with information overload and information sorting that commonly occur as part of discovery-based processes, and to enhance classroom discussion. The program was also designed to model and allow students to practice the problem-oriented approach to clinical cases, thereby enabling them to study pathology in a relevant clinical context. Features included opportunities for students to obtain additional information on the case by requesting specific laboratory tests and/or diagnostic procedures. However, students were also required to justify their diagnostic plans and to provide mechanistic analyses. The use of ATLes met most of these objectives. Student acceptance was high, and students favorably reviewed the online ''Content Links'' that made useful information more readily accessible and level appropriate. Students came to the lab better prepared to engage in an in-depth and high-quality discussion and were better able to connect clinical problems to underlying changes in tissue (lesions). However, many students indicated that the required time on task prior to lab might have been excessive relative to what they thought they learned. The classroom discussion, although improved, was not elevated to the expected level-most likely reflecting other missing elements of the learning environment, including the existing student culture and the students' current discussion skills. This article briefly discusses the lessons learned from ATLes and how similar case-based exercises might be combined with other approaches to enhance and enliven classroom discussions in the veterinary curriculum.

Departments of Pathology and Laboratory Medicine, University of Texas Health Science Center at Houston, Houston, Texas 77030, USA.


OBJECTIVE: To implement an interactive program for teaching coagulation disorders on the World Wide Web. DESIGN AND RESULTS: The core materials in this program were derived from a personal computer software program previously designed by the authors. Three modules were developed in this program: (1) a coagulation profile to display typical results of coagulation screening tests for each disorder; (2) a differential diagnosis module to generate a list of diagnoses that fit the test results in a given case; and (3) a synopsis of coagulopathy and therapy to provide essential information on disorders and therapeutic options. A total of 41 coagulation disorders were included in the knowledge base. CONCLUSIONS: Since the World Wide Web is increasingly more accessible to computer users, it has become an ideal medium for teaching purposes. Our experience with this program in teaching medical students and pathology residents at our institution has been very encouraging.

[Malignant hyperthermia is a rare condition involving a marked elevation of body temperature in response to anesthetics in genetically-predisposed individuals. It can constitute an anesthetic emergency.]

 

An educational graphic simulator was developed to provide an interactive learning environment to practice the diagnosis and treatment of malignant hyperthermia. The program incorporates a set of dynamically interacting models to present the physiologic changes associated with malignant hyperthermia and the simulated patient's response to management. Cardiovascular, respiratory, and temperature changes are presented through a graphic display of the operating room monitors. Mouse-driven input is used to manage the airway, control ventilation, manage cardiovascular and rhythm disturbances, and control fluids, electrolytes, and temperature. Medications, including dantrolene, antidysrhythmics, diuretics, and sodium bicarbonate, can be administered. Four simulated patients with different presentations of malignant hyperthermia are included to illustrate variations in the syndrome. Two of these patients are described in detail.

We have developed Windows-based software for ECG training as a tool in teaching physiology. A standard user interface allows the user to choose which arrhythmia to review. The arrhythmia is drawn in real time with sound beeps synchronized to R waves. The system also presents a brief summary or multiple choice question corresponding to the arrhythmia. A ladder diagram shows how simulate the conduction system, which consisted of 4 modules characterized by 4 parameters: automaticity, refractory period, antegrade- and retrograde-conduction time. This system has proved both useful and effective for training medical students in ECG interpretation of arrhythmias.
