Traumatic pneumocephalus.

A case is described of pneumocephalus involving both frontal lobes, following a frontoethmoidal fracture. It is noteworthy because it illustrates how extensive cerebral damage may be before it it detected. Intracerebral pneumocephalus occurs most commonly in fractures involving the frontal sinus or anterior ethmoidal/cribriform plate area. These fractures are not rare, and this potential complication should be in the minds of Ear, Nose and Throat surgeons who deal with trauma to the frontonasal region.

Closing volume in coal miners.

Closing volume and closing capacity were determined in 82 working Appalachian coal miners and in a comparable group of control subjects. Abnormalities of closing volume and closing capacity were related to other measurements of pulmonary function. The relationship of smoking history, dust exposure, and presence of pneumoconiosis and bronchitis to elevations of closing volume and closing capacity was determined. It was shown that nonsmoking miners had elevated closing volume and closing capacity when compared to control subjects. Miners who were smokers or ex-smokers also had elevated closing capacity when compared to control subjects. Neither bronchitic symptoms nor the radiographic presence of pneumoconiosis were associated with an elevation of closing volume or closing capacity.

Sex differences in the eyes of expert personality assessors: unwarranted conclusions.

In a recent paper, Haan and Livson reported sex differences between male and female psychologists in their evaluations of adult men and adult women. Their conclusions have implication for the validity of clinical assessments and were interpreted in terms of stereotypic sex role perceptions. However, their statistical analysis was in fundamental error. When the data they employed were reanalyzed, no reliable sex differences between men and women psychologists were found, a finding in accord with a number of previous investigations of this problem.

Change and sameness in personality development: unwarranted conclusions.

A recent paper by Haan and Day reports personality characteristics displaying change and sameness during the course of a longitudinal study. The personality characteristics had been classified according to statistical criteria following which the personality qualities within each category were interpreted. Thus the usefulness of the interpretation depends upon the basis for classification of the personality characteristics. The present note calls attention to three fundamental statistical errors in the Haan and Day classification scheme, errors which influence dramatically and adversely the consequent interpretations.
