ABSTRACT
An evaluation is made of Goldberg s (1992) 100 Unipolar Markers of the five-factor model of personality. The factor structure of these items in samples of older men from the Normative Aging Study and undergraduate students are examined, and both item transformation and consistency testing approaches are used to evaluate replications of the five-factor structure. Results show that the five-factor structure is difficult to replicate in the sample of older men. While item transformations and sample trimming based on a consistency test did improve the quality of the replication in this older, nonstudent sample, both methods have serious drawbacks. The five-factor solution appeared in the student sample without sample trimming or data transformation. Additionally, in both student and nonstudent samples, oblique rotation resulted in inter-factor correlations relevant to more general issues in the study of trait structure. We conclude that the 100 Unipolar Markers may be unsuitable for use in older populations or with nonstudent samples.

Air embolism produced by vaginal insufflation is an unusual but potentially lethal consequence of sexual activity, especially in the pregnant patient. Reported here is the case of a young pregnant woman who presented to the ED in full cardiac arrest, with little history to explain her condition. Despite aggressive resuscitative measures, the patient died, but her infant son was delivered via perimortem cesarean section and survived. A high level of suspicion for air embolism should be maintained for young women who unexpectedly develop cardiac arrest, particularly during sexual activity. Air embolism patients may require vigorous medical resuscitation, hyperbaric oxygen therapy, or surgical intervention to survive. The emergency physician should be familiar with the indications for perimortem cesarean delivery in the third-trimester patient presenting to the ED with cardiac arrest.
