Surgeons in the United States. Activities, output and income.

In a national surgical manpower questionnaire survey, 76% of those MD and DO surgeons who were contactable returned questionnaires that included a log diary reporting details of their daily activities. Comparisons were made of allocation of professional time, number of operations performed, and net income of respondents by physician classification (including certification), specialty, practice arrangement, age, and census division. The mean professional workweek was estimated at 46 hours for all respondents. More than two thirds of the total professional time was spent in direct patient care; about half the surgeon's time was spent in the hospital, with nearly 20% in the operating room. The median annual work load of respondents was 170 operations. Their median annual net income was $45,700.

Human fat cell sizing--a quick, simple method.

Two methods were used to determine the mean cell diameters of 37 samples of human adipose tissue, obtained by open or needle biopsy. Method I was the sizing of cells in cell suspensions and Method II was a quick, simple method of sizing cells from fixed sections. The agreement between the two methods was good (r = 0.93, P = less than 0.001). The results using Method II were slightly lower than those using Method I, and a correction factor is suggested. Method II has several advantages over Method I and we propose that it is a suitable method for sizing cells when a quick method with a permanent record is required.
