Civilian helicopters and emergency medical services in the United States have been in existence for approximately 15 years. The rapid growth of this type of health care delivery coupled with an increasing number of accidents has prompted professional and lay scrutiny of these programs. ⋯ Significant questions regarding the number of pilots in a helicopter and in a program remain to be answered. This article reviews the role of emergency medical air transport services in providing care to trauma patients, staff training and evaluation, and safety criteria and offers recommendations to minimize risks to patients and crews.

Comparative Study
Anatomical and profile analysis of the female black American nose.
An anatomical and anthropometric study was conducted that compared nasal pyramid measurements of Negroid with Caucasian skulls and surface measurements of black with Caucasian controls. Eight external surface measurements were used to develop a classification system to show the range of the female black American nose. This classification will be described along with the range of measurements on which it is based. This classification may provide a better understanding of the anatomic characteristics of the normal variation of Negroid noses, and thus improve the surgeon's ability to evaluate black patients for rhinoplasty.
