Volunteer studies of experimental, low-velocity rear-end collisions have shown a percentage of subjects to report short-lived symptoms, but the cause of these symptoms remains unknown. It is unclear whether the symptoms arise from biomechanical stress causing injury or from psychological stress causing symptom expectation and anxiety. Similarly, the cause(More)
A study was conducted to find out whether in a rear-impact motor vehicle accident, velocity changes in the impact vehicle of between 10 and 15 km/h can cause so-called “whiplash injuries”. An assessment of the actual injury mechanism of such whiplash injuries and comparison of vehicle rear-end collisions with amusement park bumper car collisions was also(More)
The shoulder is now accessible to MRI owing to recent technical advances. The major advantages of this modality include its noninvasive nature, lack of ionizing radiation, excellent contrast and anatomic resolution, multiplanar imaging capability, and ability as a single imaging modality to evaluate simultaneously for a wide variety of pathologic processes.(More)
BACKGROUND/AIMS The first main objective of the work presented in this paper was to investigate ways of optimizing the current arm patch test protocol by (1) increasing the sensitivity of the test in order to evaluate more effectively the products that are inherently non-irritating, and/or (2) reducing the costs of these types of studies by shortening the(More)

OBJECTIVE To assess differences in prevalence and cell densities of enterococci, Gram negative enterics (GNEs), yeast and Staphylococcus aureus among four genital sites and to examine whether the presence of organisms at one site affected the presence of organisms at other sites. METHODS Swab samples from the perineum, below and above the hymen, and the(More)
BACKGROUND/PURPOSE The studies presented here are intended to continue the validation of the behind-the-knee test system developed to evaluate the mechanical irritation potential of products such as catemenial pads, baby and adult diapers (which are inherently non-irritating products/chemicals). These products are intended to be worn for prolonged periods(More)
