Dislocation of the hip is a well-described event that occurs in conjunction with highenergy trauma or postoperatively after total hip arthroplasty. Bigelow first described closed treatment of a dislocated hip in 1870, and in the last decade many reduction techniques have been proposed. In this article, we review all described techniques for the reduction of hip dislocation while focusing on physician safety. Furthermore, we introduce a modified technique for the reduction of posterior hip dislocation that allows the physician to adhere to the back safety principles set for by the Occupational Safety and Health Administration.

This chapter discusses the roles of government in promoting occupational and environmental health, with a focus on the U.S. federal government. Governmental interventions, as described here, can range from non-regulatory interventions, such as dissemination of information or generation and communication of information, to establishing regulatory requirements through the promulgation and enforcement of standards and regulations. The chapter describes the U.S. laws and roles of the administrative agencies responsible for occupational and environmental health, including the Occupational Safety and Health Administration, the Mine Safety and Health Administration, and the Environmental Protection Agency. Noting the budgetary and political constraints on these federal agencies, the chapter goes on to discuss briefly the role of the public and the states. The government also plays a role when preventive efforts fail, and the chapter provides a brief summary of programs designed to provide compensation to injured workers.

Cabin air quality and thermal conditions have a direct impact on passenger and flight crew’s health and comfort. In this study, in-cabin thermal environment and particulate matter (PM) exposures were investigated in four China domestic flights. The mean and standard deviation of the in-cabin carbon dioxide (CO2) concentrations in two tested flights are 1440 ± 111 ppm. The measured maximum in-cabin carbon monoxide (CO) concentration is 1.2 ppm, which is under the US Occupational Safety and Health Administration (OSHA) permissible exposure limit of 10 ppm. The tested relative humidity ranges from 13.8% to 67.0% with an average of 31.7%. The cabin pressure change rates at the end of the climbing stages and the beginning of the descending stages are close to 10 hPa·min−1, which might induce the uncomfortable feeling of passengers and crew members. PM mass concentrations were measured on four flights. The results show that PM concentrations decreased after the aircraft cabin door closed and were affected by severe turbulences. The highest in-cabin PM concentrations were observed in the oldest aircraft with an age of 13.2 years, and the waiting phase in this aircraft generated the highest exposures.

Eula Bingham, toxicologist and former head of the Occupational Safety and Health Administration, is now at that place in her professional life where she can look back over her long career and identify its turning points and evaluate what worked and what didn't, what was important and what of lesser significance. In two interviews, she also looks at the present and the future and expresses concerns about the way we live now.
