Congenital dermal sinus cutaneous abnormalities, infection, and neurological deficits. Congenital dermal sinus is a tract from the surface layer of the skin, through the deeper tissues into the cranial or spinal cavity. The skin findings of this tract can include: The stratified squamous epithelium of the congenital dermal sinus tract can extend to the spinal fascia of the dura mater or all the way to the spinal cord. Thus, the congenital dermal sinus forms a point of entry for infection, this can allow for the formation of an abscess. Infection can then travel up the spinal cord to result in meningitis, which can
Whole body vibration varying degrees of success. Common modes of patient transport include hand carried stretcher (litter), ground ambulance, and air medical services which all contain multiple forms of shocks and whole-body vibrations. Measurements are taken with accelerometers to estimate the amount of vibration exposure to the human body. These measurements are taken at the human body or at the vibration source or surface. Measurements of different directions are taken to relate the motion direction with the response of the human body. Specifically, transfer functions can be used to determine the human response to the vibration. Measurement techniques for estimating exposures to whole
