A follow-up survey of 1,087 physicians who had graduated from the University of California, San Francisco, School of Medicine from 1951 through 1971 was completed in 1977. A total of 307 (28.2 percent) of these persons were found to have left California. Comparison of the 307 who left with the 780 who remained showed only slight and statistically insignificant differences on most variables, such as sex, academic performance in premedical and medical education, educational level and social class of parents, age at entry into medical school, ratings by admissions interviewers, choice of specialty and a wide variety of personality inventory measures. Among the variables that did differentiate were place of birth, location and prestige of premedical college, preferences for subjects in the sciences and the humanities, and the Medical College Admission Test (MCAT) scores for quantitative ability and general information. However, attempts to combine these individual differentiators into clusters or equations from which to forecast emigration from California were unsuccessful.

Number of children wanted and expected by American physicians.

Seven hundred thrity-five male and 93 female physicians indicated the number of children they would like to have; 713 and 89 indicated the number they expected to have. These questionnaire responses were related to demographic, educational, and personality test data gathered while the physicians were in medical school. The strongest predictor of both number of children wanted and expected was the size of the physician's own family of origin. Specialists in obstetrics and gynecology wanted and expected more children than those in other specialties.

A comparison of medical students from medical and nonmedical families.

A total of 1,195 students from 11 classes at the University of California, San Francisco, School of Medicine was studied. Of these, 162 were from medical and 1,033 from nonmedical families. Those from medical families were insignificantly different from their classmates on premedical scholastic achievement and Medical College Admission Test scores, but they were slightly younger and attended more prestigious undergraduate colleges. Academic and clinical performance in medical school was equivalent for the two groups. However, long-range consequences in regard to choice of specialty were observable. Psysicians from medical families were more likely than their peers to be in ophthalmology and otorhinolarngoloy, dermatology, and surgery and less likely to be in psychiatry, pediatrics, and obstericsgynecology.

An attempt to predict graduation from medical school.

Although there is less attrition from medical school now than in prior years, 500 or more students can be expected to withdraw from American medical schools during each academic year. Continuing study of the problem is, therefore, warranted. Personality inventory, cognitive, and application data, all gathered at the time of admission, were examined for 1,014 graduates and 57 dropouts; separate analyses were conducted for the 17 who departed for academic reasons and the 40 whose attrition was attributable to other causes. Correlational analyses were also conducted in which graduates, nonacademic dropouts, and academic dropouts were scaled in a 4-3-1 continuum. The best predictor of this graduation versus dropout hierarchy was given by a six-variable combination, including scores on the Quantitative ability subtest of the Medical College Admission Test and premedical grades for the last two terms, with positive weightings; personality inventory scales for status potential, socialization, and communality, also with positive weightings; and a personality scale for conformist achievement drive, weighted negatively.

Histopathologic features of the initial and early stages of experimental gingivitis in man.

The pathologic alterations occurring in the gingival tissues of humans immediately following the beginning of plaque accumulation have not heen elucidated previously. Seven males, 22--31 years of age, free of clinical manifestations of dental and periodontal disease, and exhibiting a Plaque Index score of zero for the previous 28 days served as subjects. Plaque control measures were discontinued for 8 days and biopsies were taken from the buccal marginal gingiva of the first premolars on days 0, 2, 4, and 8. Paraffin- and Epon-embedded section, treated with a variety of histochemical stains were analyzed microscopically and cell counts were done on 1-micron Epon section. At 2 and 4 days following the beginning of plaque accumulation, the vessels subjacent to the juctional epithelium exhibited vasculitis and alterations in the perivascular collagen. There was a statistically significant increase in the number of neutrophils residing in the junctional epithelium. By the end of the 8-day period, the number of small mononuclear cells, mostly lymphocytes, in the connective tissues had increased by 3-fold and the area of collagen fiber alteration by 4-fold. In addition, the number of fibroblasts per unit area of connective tissue decreased significantly. Thus, within the period of 8 days following the beginning of plaque accumulation, an early lesion exhibiting many features characteristic of delayed hypersensitivity develops.
