We designed an educational software package, RELAX, for teaching first-year anesthesiology residents about the pharmacology and clinical management of neuromuscular blockade. The software uses an interactive, problem-based approach and moves the user through cases in an operating room environment. It can be run on personal computers with Microsoft Windows (Microsoft Corp., Redmond, WA) and combines video, graphics, and text with mouse-driven user input. We utilized test scores 1) to determine whether our software was beneficial to be the educational progress of anesthesiology residents and 2) to compare computer-based learning with textbook learning. Twenty-three residents were divided into two groups matched for age and sex, and a pretest was administered to all 23 residents. There was no significant difference (P > 0.05) in the pretest scores of the two groups. Three weeks later, both groups were subjected to an educational intervention; one with our computer software and the other with selected textbooks. Both groups took a posttest immediately after the intervention. The test scores of the computer group improved significantly more (P < 0.05) than those of the textbook group. Although prior to the study the two groups showed no statistical difference in their familiarity with computers, the computer group reported much higher satisfaction with their learning experience than did the textbook group (P < 0.0001).

Surgeons in America in the eighteenth century treated wounds, fractures, dislocations, and gunshot injuries of the skeletal structures and also contended with osteomyelitis and tuberculosis of bones and joints. In meeting this challenge, they proved innovative, adaptive and courageous, and developed principles of surgery, some of which still are in use today.
The history of the Campbell Clinic is deeply seated in the accomplishments of Dr. Willis Cahoon Campbell. At the age of 26 he decided to live in Memphis and become an orthopaedic surgeon. At the time Memphis was growing rapidly and orthopaedic surgery was evolving as a surgical specialty. These conditions provided him with the opportunity to do many things that were visionary. He established the Campbell Clinic and the orthopaedic department of the medical school and aided in founding hospitals and clinics for private patients and patients who were indigent. His major contributions to the field of orthopaedics include the recruitment of outstanding associates who would follow and build on his high standards of performance, the establishment of an outstanding residency program, the publication of Campbell's Operative Orthopaedics, and providing leadership for many orthopaedic surgeons. It can be said without reservation that Campbell and the early staff members played an important role in the growth of orthopaedic surgery essentially from its infancy and into the second half of the century. The legacy of excellence that Campbell and all the members of the staff established has continued to be the hallmark of the Campbell Clinic.

RATIONALE AND OBJECTIVES: Information overload is a significant problem for the modern radiologist. This prospective study compares the instructional effectiveness of a multimedia textbook (HyperLung) with a lecture. HyperLung is a radiologic multimedia textbook about imaging diffuse lung disease created using a multimedia authoring tool, the Annotator (the University of Iowa Second Look Computing, Iowa City, IA), on the Apple Macintosh computer (Apple Computer, Cupertino, CA). METHODS: Forty-nine staff physicians and residents in the Department of Radiology were randomized to receive instruction either by HyperLung or by a lecture. The instructional content was the same in both groups, and both groups were tested before and after instruction. The actual time spent in each instructional situation was recorded. RESULTS: The instructional effectiveness of the multimedia textbook and lecture was equal. The instructional efficiency of HyperLung was only 60% of the lecture. Users of the multimedia textbook found it enjoyable and straightforward to use. CONCLUSIONS: Multimedia textbooks have a promising future in radiology education.

Born in Wetter, Germany, in 1500, Johannes Eichmann (Dryander) studied medicine and anatomy at the University of Paris from 1528 to 1534. In 1535, he was appointed professor of medicine at the University of Marburg. During the next year he held two public dissections, and in 1536 he was the author of the first text illustrating a Galenic dissection of the human brain. An expanded edition of this early book, the Anatomiae pars prior, was published in 1537. These texts represented an important transition from the dogma of medieval scholasticism to the precise observations of Vesalius. The books depicted the brain in eight figures, with four additional plates describing the skull, skull base, and cranial sutures. Detailed illustrations of the dura mater, cerebral cortex, and posterior fossa structures with clear, but inaccurate, relationship to the cranial nerves demonstrated Dryander's reliance on his own dissections. In 1542, he published a translated edition of Mundinus' anatomy. As was common at that time, the text plagiarized a portion of Vesalius' Tabulae sex, which resulted in the famous anatomist's anger. Despite this, Dryander continued to write on medical subjects as well as mathematics and astrology until his death in 1560. Because he was a progenitor of rational scientific thought, his earlier books represented an important advance in the progression to modern anatomic description and illustration.
Serefeddin Sabuncuoğlu (AD 1385-1468?) is the author of Cerrahiyyetü'l-Haniyye (Imperial Surgery), which was written in Turkish in 1465. It was the first illustrated textbook of surgery in the Turkish medical literature, containing color illustrations of surgical procedures, incisions, and instruments. Sabuncuoğlu, a pioneer of surgery, developed numerous original techniques in a variety of surgical specialties. He described surgical management of spinal trauma, epilepsy, migraine, facial palsy, hemiplegia, low back pain, cranial fracture, and hydrocephalus. The aim of this study is to describe his contributions to neurosurgery.
JOHN BINGHAM ROBERTS (1852-1924) of Philadelphia was an active general surgeon in the latter 19th and early 20th centuries. He made pioneering contributions to a number of areas of surgery. From 1880 until the end of his career, he was one of the few American surgeons to advocate an aggressive exploratory approach to cranial fractures in an effort to avoid consequences such as infection, delayed seizures, and insanity. In his 1885 article in the Transactions of the American Surgical Association titled "The Field and Limitation of the Operative Surgery of the Human Brain," he predicted that with antiseptic precautions and the growing knowledge of cerebral localization, operations on the brain would become commonplace. This work predated that of Horsley, Keen, and many others. Roberts had a continuing interest in head injuries, cranial fractures, and the development of trephines and burrs for reconstructive cranial work, but his active enthusiasm for brain surgery diminished in the 1890s. Nevertheless, Roberts was a very prolific teacher and leader in American surgery who is perhaps best remembered for his monographs and textbooks on general, orthopedic, plastic, and reconstructive surgery.
