BACKGROUND Extensive spread of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in the United States, and the concomitant increase in severe invasive staphylococcal infections, including osteomyelitis, in healthy children, has led to renewed interest in Panton-Valentine leukocidin (PVL). However, the pathogenetic role of PVL in… (More)
The patterns of activation of splenius capitis, semispinalis capitis, transversospinalis, and levator scapulae muscles were studied during various head-neck positions, movements, and isometric tests in 19 healthy human subjects. Myoelectric activities were recorded with intramuscular bipolar wire electrodes. Cervical computerized tomography of each subject… (More)
To determine the postural role of longus colli (LC) and dorsal neck muscles, we have studied the relationship between their cross-sectional areas related to their force of contraction and the lordosis and the length of the cervical spine. This study was carried out in 36 healthy subjects. Muscle cross-sectional areas were measured by computerized… (More)
Splenius capitis (SPL) electromyograms were recorded using conventional surface and intramuscular wire electrodes simultaneously during various head-neck movements and isometric tasks to test the selectivity of surface electrodes for SPL myoelectric signals. The insertion of bipolar wire electrodes was aided by a computerized tomographical study of each… (More)
In this paper we overview the achievements of the IDD European project, which aims at defining a new framework for the design of automotive systems. In particular, starting from the weaknesses of the current design process, especially as regards issues related to diagnosis (diagnosability analysis, generation of the FMEA-Failure Mode Effect Analysis,… (More)
Paraganglioma of the filum terminale is a rare tumor but well described in the neurosurgery and pathology literature. Few MRI reports are mentioned. Paraganglioma, often misdiagnosed with ependymoma or schwannoma on MRI images, must be kept in mind, when a highly vascular lesion with serpentine vessels is observed.
Biomechanical models of the cervical spine require knowledge of the position, size and orientation of the individual muscles that act on the cervical spine. We have developed a technique to stereometrically measure anatomical specimens. The apparatus is composed of three graduated metallic rods, which slide along a fixed support. This method is accurate to… (More)
A method is described for control of a bicipital groove projection using a tele-controlled table with centering guided by direct screen imaging: the patient is placed in contralateral anterior oblique position with the arm in antepulsion to project the groove into the supraspinal fossa on a lateral scapular image.
Historical aspects and anatomophysiologic features of posterior lumbar vertebral joints are summarized and results of arthrography of 55 joints presented, together with a simple, original method for performing this examination. Normal anatomic appearances condition understanding of principal lesions encountered, particularly with respect to compression of… (More)
