In the ECE 127 Regulation on pedestrian leg protection, as well as in the Euro NCAP test protocol, a legform impactor hits the vehicle at the speed of 40 kph. In these tests, the knee is fully extended and the leg is not coupled to the upper body. However, the typical configuration of a pedestrian impact differs since the knee is flexed during most of the gait cycle and the hip joint applies an unknown force to the femur.

This study focused on a better understanding and characterization of the submarining phenomenon that occurs in frontal crashes when the lap belt slides over the anterior superi or iliac spine. Submarining is the consequence of the pelvis kinematics relative to the lap belt, driven by the equilibrium of forces and moments applied to the pelvis. The study had two primary purposes; the first was to provide new PMHS data in submarining test configurations, the second was to investigate the Hybrid II and Hybrid III dummies biofidelity regarding submarining.

Rib fractures constitute a good indication of severity as there are the most frequent type of AIS3+ chest injuries. In 2008, Trosseille et al. showed a promising methodology to exhibit the rib fracture mechanisms, using strain gauges glued on the ribs of Post-Mortem Human Subjects (PMHS) and developing a specific signal analysis.

Occupant protection in rear impact involves two competing challenges. On one hand, allowing a deformation of the seat would act as an energy absorber in low severity impacts and would consequently decrease the risk of neck injuries. However, on the other hand, large deformations of the seat may increase the likelihood of occupant ejection in high severity cases.

Introduction: Patients with prominent median lobe hyperplasia and/or high International Prostate Symptom Score (IPSS) are often contraindicated for prostate brachytherapy, mainly because of the risk of post-implant urinary retention. We evaluated an approach combining in the same operative step a limited transurethral resection (TURP) of the median lobe, immediately followed by permanent implant-free seed brachytherapy.

Methods And Materials: From January 2007 to November 2008, 22 patients underwent a customized limited TURP of their median lobe immediately before brachytherapy.

Purpose: The retrospective use of prostate cancer tissue is crucial to design tumor marker prognostic studies. We hypothesize that comparison between recent and more historical cases could introduce biases due to stage and grade migration upon time.

Design: We reviewed 544 margin-free specimens from patients treated for clinically localized prostate cancer by radical prostatectomy between 2000 and 2005.

Thoracic injury criteria and injury risk curves in side impact are based on impactor or sled tests, with rigid or padded surfaces while airbags are very common on current cars. Besides, the loading is generally pure lateral while real crashes or regulations can generate oblique loadings. Oblique tests were found in the literature, but no conclusion was drawn with regard to the effect of the direction on the injury outcome.
