4 false-positive results occurred per radiograph for the control group.
Conclusion: CAD has
the potential to detect approximately P5091 half of the lesions overlooked by human readers at chest radiography. (C) RSNA, 2009″
“Shuddering attacks are benign shivering movements occurring in young children. The etiology is unknown; however, a relationship to essential tremor has been postulated. A series of 12 consecutive children were identified over a 6-year period ending January 1, 2007. Shuddering attacks were diagnosed based on descriptive history and videotape review. Their referral diagnosis was epilepsy in 7 (58%) and movement disorder in 5 (42%). The referring physician never suspected the diagnosis. The age of onset ranged from 8 months to 2 years (mean 13 months). Family history was negative for essential
tremor. None had epileptiform discharges on electroencephalography (EEG). All children were followed for 2 to 8 years (mean 6.3). Complete remission was noted by 3 to 7 years (mean 5.6) of age, and none had subsequent tremor during follow-up. In conclusion, shuddering attacks are frequently misdiagnosed leading to unnecessary investigations or treatment. No association with essential tremor was found neither in the child nor in the family.”
“Study Design. Prospective cohort study.
Objective. To evaluate the relative efficacies of soft and rigid collars for restricting both the full, active and functional ranges of motion (ROM) of the cervical spine during 15 activities Selleck WH-4-023 of daily living (ADLs).
Summary of Background Data. Cervical collars are frequently used for the purpose of limiting cervical motion after surgical procedures or as a treatment for certain injuries. Rigid collars are generally believed to reduce cervical motion to a greater extent than soft collars but the latter are often preferred by patients because of their
greater comfort. Although there are some data to suggest that soft collars restrict full, active ROM (i.e., the extremes of motion) to a lesser degree than rigid braces, there are currently no comparative studies that have assessed the effects of these 2 types of cervical collars on the PF-562271 functional ROM that is required to perform multiple ADLs.
Methods. In this investigation, a previously validated electrogoniometer device was used to quantify both the full, active ROM of 10 subjects as well as the functional ROM they exhibited during a series of 15 ADLs. For each individual, these ROM measurements were repeated after the application of both a soft collar and a rigid orthosis.
Results. The soft collar limited flexion/extension, lateral bending, and rotation by 27.1% +/- 9.9% (mean +/- standard deviation), 26.1% +/- 4.8%, and 29.3% +/- 10.3%, respectively. The corresponding reductions in ROM with a rigid collar were 53.7% +/- 7.2%, 34.9% +/- 6%, and 59.2% +/- 5.3%, respectively.
