Aneurysms of the thoracic aorta remain a challenge to surgeons. My early experience began in 1950, when I excised a large aneurysm in one of Dr Alfred Blalock's patients. The patient survived and was cured. This experience convinced me that aortic aneurysms could be treated successfully by aggressive surgical means. Treatment, however, has changed from the early emphasis on excision of the lesion to the present belief in restoration of circulatory continuity using a suitable Dacron graft, or endoaneurysmorrhaphy.

In 1968, the Journal of the American Medical Association published a paper on the "Initial clinical experience with intraaortic balloon pumping in cardiogenic shock," which gave the results of the first clinical use of the procedure developed in our laboratory. For more than 2 years, our group was the only one using intraaortic balloon pumping clinically. Later, intraaortic balloon pumping was used by others, and despite poor clinical salvage, the hemodynamic benefit was demonstrated convincingly. At the present time, approximately 70,000 balloon pump procedures are performed annually.
A 4-month "minisabbatical" (June through September 1992) provided me with a selected view of the current status of thoracoscopic surgery as it is being performed in Europe. This experience comprised visits to three countries and a total of five clinical units doing endoscopic surgery. Observations are grouped into five categories: (1) the clinical spectrum of thoracoscopic procedures, (2) operating room design, (3) the evolution of instrumentation and imaging, (4) educational programs, and (5) strategies for testing innovative technologies. This short visit convinced me of the need for greater communication with our European colleagues.

First developed more than 20 years ago as a research tool for investigations of myocardial infarction, the pulmonary artery or Swan-Ganz catheter has gained general usage as a valuable clinical tool. Its development paralleled the rapid growth of technological advancements in clinical medicine. Rapid incorporation of technological advancements into clinical practice, however, is not without risk. Care must be taken to assure that clinicians possess the understanding of both basic concepts and requisite hardware to provide quality patient care. Equipment selection and calibration, patient selection, data interpretation, potential complications, troubleshooting, and procedure limitations must all be considered. Broader application of the Swan-Ganz catheter in surgery, anesthesiology, and critical care as well as in cardiology has provided information on hemodynamics that has had considerable impact on diagnostics as well as on therapy for patients with a wide variety of clinical conditions.

The paper first describes the subjective experience of chronic ulcerative colitis. Using autobiographical data some of the intra- and inter-personal strategies for coping with the disease are outlined. Then, selective socio-medical issues arising from the data--the relationships between physical and social events, denial and normalisation of illness, doctor-patient communications, and lay knowledge and perceptions--are elaborated. Finally suggestions for the social management of patients with ulcerative colitis are drawn out. It is argued that the importance of the subjective experience, as well as the physical process of the disease must be confronted by the physician, that the counseling of colitics should aim, where possible, to encourage normal social development, that the possibilities of the life-threatening nature of the disease and the type of curative surgery should be addressed at an early stage by the patient and their family and that patients should be allowed to do "grief-work" to help them to come to terms with the disease and its likely outcomes.
