Axoval neuropathy as initial manifestation of primary amyloidosis: report of a case submitted to bone marrow transplantation.

Amyloidosis is a syndrome characterized by deposition of a highly insoluble protein material in the extracellular space that may affect several organs. It may be generalized and idiopathic (primary amyloidosis). We describe the case of a 48 years-old woman with axonal neuropathy associated with proteinuria, whose final investigation resulted in diagnosis of primary amyloidosis (AL). She was submitted to autologous bone marrow transplantation. We discuss some aspects related to diagnosis of neuropathy and current treatment of AL.

Web-based learning in undergraduate medical education: development and assessment of an online course on experimental surgery.

In order to increase the number of practical and discussion classes offered to students in the traditional-curriculum scenario, while decreasing the lecture-based ones and to create an online community to share knowledge on surgery, we developed and assessed the first online course for undergraduate medical students on experimental surgery at the Federal University of Sao Paulo-UNIFESP, Brazil. The purposes of the present study are: describe and discuss the process and the lessons learned involved in developing an undergraduate web-based course and analyze the students' attitude towards this educational environment. A group of medical students was taught online during 5 weeks on the theory of experimental surgery through video quizzes, required readings, collaborative activities using discussion board and asynchronous communication. The students' knowledge gain, their web session variables and the results of the course evaluation were used to support our study. The students have significantly improved their knowledge on experimental surgery after the course. Among factors in the online course that could possibly have contributed to this gain, the interactive activities (video quizzes), key element in our online material, seemed to be promising for candidates. The evaluation results demonstrated high levels of course functionality, effectiveness of its online content and acceptance among medical students. This study indicated that a web-based course for undergraduate students may be successfully developed and implemented in medical settings and the students seem to be quite supportive. We encourage undergraduate medical learning strategies involving the Web.

Computer aided learning versus standard lecture for undergraduate education in urology.

PURPOSE: The current model of undergraduate medical education is under debate since knowledge retention and student interest seem to be decreasing. To clarify this situation we developed and evaluated a computer aided learning program using a multimedia presentation about prostate cancer for undergraduate teaching in urology. MATERIALS AND METHODS: A total of 60 medical students from years 2 and 3 were divided into group 1-31 who used the multimedia program and group 2-29 who attended a standard lecture on the same subject. At the end the level of knowledge acquisition for the 2 groups was evaluated by a multiple choice test. Group 1 students also answered a questionnaire about subjective feelings on computer based teaching. RESULTS: Test performance in groups 1 and 2 was similar (60% vs 62% correct answers, p >0.05). On the other hand, 23 of 31 students using the multimedia program believed that it did not adequately replace the instructor and interaction with a mentor still seems to be relevant. CONCLUSIONS: According to this study computers and multimedia programs can be used for undergraduate education in urology, providing that direct contact with an instructor is concomitantly offered to students.

[The role of distance education in continuing medical education: a critical review].

This paper reviews findings of recent literature which have systematically evaluated outcomes of continuing medical education programs worldwide, methods for measuring especific demands in medical areas, and quality and reliability of contents related to such programs. Particular features of the Brazilian health context and internet technologies are described, as well as possible directions towards life-long medical education development in Brazil for the next few years.

[Computing in medical practice].

OBJECTIVES: Currently, information technology is part of several aspects of our daily life. The objective of this paper is to analyze and discuss the use of information technology in both medical education and/or medical practice. SOURCES: Information was gathered through non-systematic bibliographic review, including articles, official regulations, book chapters and annals. Direct search and search of electronic databanks in Medline and Lilacs databases were also performed. SUMMARY OF THE FINDINGS: This paper was structured in topics. First, there is a discussion on the electronic medical record. The following aspects are presented: history, functions, costs, benefits, ethical and legal issues, and positive and negative characteristics. Medical decision-support systems are also evaluated in view of the huge amount of information produced every year regarding healthcare. The impact of the Internet on the production and diffusion of knowledge is also analyzed. Telemedicine is assessed, since it presents new challenges to medical practice, and raises important ethical issues such as "virtual medical consultation." Finally, a practical experience of modernization of a pediatric outpatient center by the introduction of computers and telecommunication tools is described. CONCLUSIONS: Medical computing offers tools and instruments that support the administrative organization of medical visits, gather, store and process patient's data, generate diagnoses, provide therapeutical advice and access to information in order to improve medical knowledge and to make it available whenever and wherever adequate decision-making is required.
