conclusions most cases of splenectomy in our center caused by trauma, and among the different types of trauma, blunt trauma is the dominant cause. road traffic accidents, in particular motor vehicle accidents, especially motorbike injures, are the most frequent cause of splenectomy. due to the instability of trauma patients, a mortality rate of 8% seems to be reasonable for splenectomy. rnwe re...

the direct torque control (dtc) of interior permanent magnet synchronous motor (ipmsm) offers simple structure and fast torque response. the conventional switching table-based dtc (st-dtc) presents some disadvantages like high torque and flux ripple and also variable switching frequency. this paper investigates the improved st-dtc strategies to reduce both torque and flux ripple in dtc of ipmsm...

Although airbags reduce the overall risk of injury and death from motor vehicle accidents, the airbag may cause injuries during deployment. We present a case of apparently isolated sternal fracture caused by airbag deployment during a motor vehicle crash and we discuss the ultrasonographic diagnosis. We also examine the mechanism of injury caused by the airbag.

Epidemiology of head injury in childhood Between the ages of 1 and 14 years accidents constitute the greatest single cause of death and head injuries account for 40% of these, amounting to 403 in the United Kingdom in 1985.1 Only about one quarter of children who rece...

PRIMARY OBJECTIVE To analyse the relationship between motor vehicle collision factors and TBI. RESEARCH DESIGN Retrospective design analysed the difference between the types of brain injuries sustained in distinct collision configurations. METHODS AND PROCEDURES Medical charts and police accident reports were reviewed for individuals sustaining TBI in 168 motor vehicle collisions between 19...

The article by Snyder and Bloom highlights the importance of physicians’ actively participating in the legislative process when medicolegal issues are involved. The specific forensic questions addressed by the authors focus on physician reporting of potentially impaired drivers—a problem that has been precipitated by the complexities involved in determining fitness to drive in the elderly. It i...

In a world overwhelmed by information, how can news media messages and their stewards break through that barrier and compel us to sit up and take notice? Much depends upon a story’s meaning and relevance to our own lives. Improving these qualities of communication requires a thorough knowledge of a complex arena and some means with which to reach its gatekeepers and, ultimately, penetrate its v...
