Requiring students to have computers: questions for consideration.

For the past several years a dialogue has been taking place in the offices, lounges, and meeting rooms of medical schools about whether medical students should be required to bring or purchase computers when they enter school. Microcomputers offer educators a unique opportunity to provide students with access to computer-assisted instruction, asynchronous communication, and extensive knowledge bases. However, there is still no evidence attesting to the effectiveness of computers as teaching or learning tools in medical education. The author raises questions that schools need to consider before requiring students to own computers: What kind of computer best suits their needs? What might impede using computers to teach? And who is currently requiring computers? In addressing the last question, the author presents information about 15 North American schools that currently require their students to have computers, reporting each school's software and hardware requirements; how each expects students to use the computers; and who covers the cost of the computers (the students or the school). Finally, he argues that major institutional commitment is needed for computers to be successfully integrated into any medical school curriculum.

Pharmacy practice in the United States Army.

The current status of pharmaceutical services in the United States Army Medical Department is described. The mission of the Army Medical Department is to ensure the health of the soldier during times of peace and war. Of the 225 commissioned pharmacy officers currently on active duty, 156 are assigned to U.S. Army medical centers and community hospitals in the United States, and 29 are stationed at hospitals in Europe, Korea, Panama, and Japan. Army pharmacy officers are supported by 879 Army-trained pharmacy technicians and 319 civilian pharmacists employed by the Army. Army Medical Department hospital pharmacies provide inpatient and ambulatory-care services as well as specialized nuclear pharmacy, oncology, investigational drug, and materials development services. Pharmacy officers assigned to the Pharmacy Branch of the U.S. Army Academy of Health Sciences conduct 17-week technician training programs six times a year and provide other pharmacy courses and continuing education programs. The U.S. Army Allergen Extract Laboratory dispenses diagnostic and immunotherapy agents by mail in response to prescriptions submitted by military allergy clinics. Pharmacy officers may be deployed with field hospitals during times of combat or for extended training exercises in places such as Egypt, Grenada, and Honduras. Pharmacy officers may also be assigned to three- or four-year tours of duty in Army hospitals located in Europe. In the future, the emphasis of Army pharmacy practice will be on the expansion of clinical pharmaceutical services and the development of advanced interactive communication systems, quality assurance programs, and peer-review programs.

Scintigraphy of gastrointestinal hemorrhage: superiority of 99mTc red blood cells over 99mTc sulfur colloid.

The relative efficacy of 99mTc sulfur colloid and in vitro-labeled 99mTc red blood cells in detecting and localizing gastrointestinal hemorrhage was evaluated in a prospective tandem study of 100 patients referred for suspicion of gastrointestinal tract hemorrhage. Thirty-eight true-positive scintigrams were obtained with 99mTc red blood cells, whereas 99mTc sulfur colloid detected only five sites of hemorrhage. Scintigraphic findings were corroborated by clinical, endoscopic, arteriographic, and surgical findings. 99mTc red blood cells were clearly superior, with a sensitivity of 93%, specificity of 95%, and overall accuracy of 94% in detecting and localizing gastrointestinal hemorrhage.

Scintigraphic detection of occult hemorrhage using RBCs labeled in vitro with technetium Tc 99m sodium pertechnetate.

Scintigraphy with RBCs labeled with technetium Tc 99m sodium pertechnetate effectively located the source of hemorrhage in a patient receiving long-term anticoagulant therapy. (The patient was initially seen with a large hematoma on the flank.) More important, the procedure was used to monitor activity in this otherwise-occult bleeding site. Scintigraphic studies may be useful in the management of these difficult clinical problems.
