Modafinil, a novel stimulant which has several remarkable features that distinguish it from other stimulants, has been developed by Lafon, a French pharmaceutical company. Unlike the amphetamines, for example, modafinil is reported to have minimal peripheral side effects at therapeutic doses. It also appears to have a low abuse potential, does not interfere(More)
BACKGROUND Recent investigation into the push-pull effect (PPE), the reduction of +Gz tolerance when preceded by less than +1 Gz, has focused on centrifuge studies to demonstrate the presence of adverse cardiovascular responses. Maneuvers found to cause the Push-Pull Effect (PPEM) have not been studied previously in U.S. Air Force (USAF) fighter aircraft.(More)
BACKGROUND A recent Canadian Forces CF-18 Hornet aircraft accident has focused interest on the push-pull effect (PPE). PPE has not previously been identified in U.S. Air Force (USAF) G-Induced Loss of Consciousness (G-LOC) Accidents. The presence of maneuvers known to cause the push-pull effect (PPEMs) that lead to G-LOC accidents suggests that PPE is(More)
Initial high-G centrifuge training of USAF fast jet pilots was instituted in 1985. Also, since the mid-1980's, pilot awareness of G-induced loss of consciousness (G-LOC) has been enhanced by briefings, videotapes, and safety articles. Aircraft accidents caused by an improperly performed anti-G straining maneuver (AGSM), however, continue to occur.(More)
Under the auspices of the European Command (EUCOM) Military-to-Military Exchange Program, the authors participated in 13 trips to visit aeromedical facilities of nine Eastern European nations (Albania, Belarus, Bulgaria, Czech Republic, Hungary, Lithuania, Poland, Romania, and Slovakia). In addition, eight of these Eastern European nations visited United(More)
UNLABELLED We compared the cancer incidence of male United States Air Force (USAF) aircrew (342 cancers, 532,980.97 man-years) with non-flying Air Force officers (827 cancers, 1,084,370.08 man-years) between 1975-89. METHODS Incident cancer cases for both aviators and non-flying officers were obtained from USAF hospitalization records. Age-adjusted(More)
U.S. Air Force (USAF) regulations do not recommend the routine movement of obstetrical patients greater than 34 weeks gestation. However, U.S. Department of Defense and embassy physicians throughout Europe continually request aeromedical movement of obstetrical patients greater than 34 weeks gestation. Therefore, a year-long prospective review of obstetric(More)
In-flight incapacitation of a fully trained crewmember due to a serious underlying medical condition is a rather infrequent event. In order to delineate the extent and nature of the incapacitation problem we reviewed the data base at the Air Force Safety and Inspection Center for all incidents coded for incapacitation, preexisting disease, or other acute(More)
INTRODUCTION Previous studies have determined that spatial disorientation (SD) causes 0.5-23% of aircraft crashes, but SD-related crash and fatality rates in different aircraft types have not been systematically studied. METHODS SD crashes for the fiscal years 1990 to 2004 and aircraft sortie numbers for all U.S. Air Force (USAF) aircraft were obtained(More)
