Protecting the immunocompromised patient: the role of the hospital clinical engineer.

While the discipline of clinical engineering has long been limited to the area of medical equipment management, few areas in hospital engineering practice so closely meet the literal definition of "clinical" engineering as the care of the immunocompromised patient. Although ventilation has been the domain of the plant maintenance department, the increasing numbers of clinical engineers being given responsibility for plant functions, as well as the critical nature of the topic, make the care of the bone marrow transplant (BMT) patient an appropriate area of clinical engineering practice. Further, as clinical engineering branches out of the equipment management area, the clinical engineer can be truly termed the "hospital engineer".

Hyperextension strain or "whiplash" injuries to the cervical spine.

Purpose: To define "whiplash" radiologically.

Material And Methods: A full cervical spine radiographic series (including flexion and extension views) was reviewed in 40 patients with clinically proven "whiplash" injuries and compared to the radiographs in 105 normal controls. The level and degree of kinking or kyphosis, subluxation, and the difference in the amount of fanning between spinous processes on flexion and extension films were measured in each patient.
