Military medical modeling and simulation in the 21st century.

As we enter the 21st century, military medicine struggles with critical issues. One of the most important issues is how to train medical personnel in peace for the realities of war. In April, 1998, The General Accounting Office (GAO) reported, "Military medical personnel have almost no chance during peacetime to practice battlefield trauma care skills. As a result, physicians both within and outside the Department of Defense (DOD) believe that military medical personnel are not prepared to provide trauma care to the severely injured soldiers in wartime. With some of today's training methods disappearing, the challenge of providing both initial; and sustainment training for almost 100,000 military medical personnel is becoming insurmountable. The "training gap" is huge and impediments to training are mounting. For example, restrictions on animal use are increasing and the cost of conducting live mass casualty exercises is prohibitive. Many medical simulation visionaries believe that four categories of medical simulation are emerging to address these challenges. These categories include PC-based multimedia, digital mannequins, virtual workbenches, and total immersion virtual reality (TIVR). The use of simulation training can provide a risk = free realistic learning environment for the spectrum of medical skills training, from buddy-aid to trauma surgery procedures. This will, in turn, enhance limited hands on training opportunities and revolutionize the way we train in peace to deliver medicine in war. High-fidelity modeling will permit manufacturers to prototype new devices before manufacture. Also, engineers will be able to test a device for themselves in a variety of simulated anatomical representations, permitting them to "practice medicine".

Renal syndromes of malaria.

Malaria is a disease of the erythron, but as would be expected with involvement of so vital an organ, serious secondary dysfunction of other organs such as the brain or kidneys commonly occurs. The body ultimately acquires defences against red cell parasitism, but when these do not culminate in effective phagocytic clearance of plasmodial antigens, injury to such organs as the liver and kidneys may result. All of the renal syndromes here described may occur in such close correspondence with malarial parasitism that a causative role in some cases is justifiably assumed. However, since all may occur in contexts other than malaria, in malarial as well as non-malarial countries, none is pathognomonic and none constitutes independent evidence of malarial infection. Indeed, though experimental malaria has had but a limited role in delineating the scope of possible malarial injuries to the kidney, the experiments of nature here described reveal natural malaria to be a versatile model system simulating most of the spectrum of known renal responses. The first three syndromes described are more or less direct consequences of unmodified malarial infection; the latter three reflect the intervention of immunity.
