In recent years, professionalism in medicine has gained increasing attention. Many have called for a return to medical professionalism as a way to respond to the corporate transformation of the U.S. health care system. Yet there is no common understanding of what is meant by the word professionalism. To encourage dialog and to arrive eventually at some consensus, one needs a normative definition. The author proposes such a definition and asserts that the concept of medical professionalism must be grounded both in the nature of a profession and in the nature of physicians' work. Attributes of medical professionalism reflect societal expectations as they relate to physicians' responsibilities, not only to individual patients but to wider communities as well. The author identifies nine behaviors that constitute medical professionalism and that physicians must exhibit if they are to meet their obligations to their patients, their communities, and their profession. (For example, "Physicians subordinate their own interests to the interests of others.") He argues that physicians must fully comprehend what medical professionalism entails. Serious negative consequences will ensue if physicians cease to exemplify the behaviors that constitute medical professionalism and hence abrogate their responsibilities both to their patients and to their chosen calling.

Our results suggest that the teaching of professionalism in undergraduate medical education varies widely. Although most medical schools in the United States now address this important topic in some manner, the strategies used to teach professionalism may not always be adequate.

Of 44 children with hemolytic-uremic syndrome seen at Milwaukee Children's Hospital, 15 (34%) had neurological involvement. This group contained 8 boys and 7 girls, with a mean age of 3 1/4 years. Twelve patients had seizure within 48 hours of admission. Seizures were associated with hypertension, fever, hyponatremia, or hypocalcemia. Other neurological symptoms included altered consciousness, behavioral changes, diplopia, and dizziness. Hemiparesis (4 patients), eye involvement (7 patients), decerebrate posturing (2 patients), and ataxia (1 patient) were present on physical examination. Cerebrospinal fluid examination showed increased protein in 4 of 11 patients. Electroencephalograms were abnormal in all 9 patients tested. Computed tomographic and radionuclide scans showed evidence of vascular abnormalities in 4 of the 14 patients studied. Complete neurological recovery occurred in only 6 of the 15 children, while the remaining 6 demonstrated residual hemiparesis, seizures, and cortical visual defect. In those children with neurological involvement, there was a higher incidence of residual hypertension (49% versus 11%), chronic renal damage (40% versus 3.5%), and death (28% versus 0%), suggesting that central nervous system involvement indicates severe hemolytic-uremic syndrome.
