If any of you have missionary friends, please pass this on. There is a self-teaching (well, almost) medical tutorial for use by non-medical missionaries working in remote areas. It focuses on cookbook-type diagnosis, using logical protocols/flow diagrams with no medical jargon. The diagnostic system is not of use in the West. The course is available for free download at villagemedicalmanual.org. It requires the use of the Village Medical Manual, currently in its 6th edition, from William Carey Library, cost less than $30. I wrote the course as well as the manual. If there are any groups interested in a 10-day hands-on course, I'm open to traveling at my own expense, always looking for ways to "student-proof" the materials.
