We believe that investigations into back pain and spinal changes in microgravity will contribute significantly to our knowledge and understanding of factors that cause back pain and the influence of spinal cord distraction on sensory and autonomic dysfunction. This information may have clinical implications for the treatment and rehabilitation of patients(More)
BACKGROUND Noise and vibration are stressors that may adversely affect the well-being of infants and children being transported between facilities. Although the problem has been recognized, little has been done to rectify the situation.

PURPOSE To determine what growth rate is acceptable before recommending histologic diagnosis of solid breast lesions diagnosed as fibroadenoma at fine-needle aspiration biopsy (FNAB). MATERIALS AND METHODS For 1,070 consecutive patients with breast lesions diagnosed as fibroadenoma at FNAB, three measurements of each mass were performed at the initial(More)
PURPOSE This study was done to produce enhanced fetal biometry charts and graphs presenting percentile values as a function of fetal age. METHODS The relationships between the ultrasound measurements of 10 fetal parameters and menstrual age were determined by a cross-sectional study. Data were obtained from 508 to 790 fetuses. Anatomic structures were(More)

PURPOSE To evaluate whether helmets increase the incidence and/or severity of cervical spine injury; decrease the incidence of head injury; and/or increase the incidence of collisions (as a reflection of adverse effects on peripheral vision and/or auditory acuity) among young skiers and snowboarders. METHODS During one ski season (1998-99) at a world(More)
The diurnal height change reported to occur in young adults was investigated to characterize changes in the lumbar range of motion, spinal profile, and range of motion of the back. Twelve subjects aged 18-22 years were measured using stereophotography and standard clinical examinations in the evening and after a minimum of 8 hours of complete bed rest. The(More)
We conducted a prospective cohort study to determine whether administration of large doses of the corticosteroid methylprednisolone following spinal cord injury as recommended in the National Acute Spinal Cord Injury Study-2 (NASCIS-2) protocol results in an increased incidence of avascular necrosis (AVN) of the femoral or humeral head. All subjects were(More)
