I wonder if the techniques used in detecting internal damage to the body by
electricity can also be used to detect damage due to microwaves and other waves
used on us. Another question, where is the doctor willing to perform these
tests? What do you think?
Advanced Diagnostic Methods: To diagnose occult damage to muscle, nerve and
bone - which may later be aggressively treated surgically - Electrical Trauma
Program collaborators from the Department of Radiology are employing new
strategies in magnetic resonance (MR) imaging to locate and quantify tissue
injury and monitor response to therapy. A very low field Instrumentarium MEGA-4
(0.1 T) unit has been installed in the emergency ward to permit rapid study
before a patient is transported to the intensive care unit. The 0.1 T unit
permits higher sensitivity to tissue protein - water interactions (thus, edema),
and it allows simultaneous use of resuscitation equipment during imaging. In the
laboratory, more advanced strategies are being developed: MR angiography can
both detect damage to vasculature and monitor tissue perfusion; and MR sodium
imaging, by distinguishing changes in extra-cellular and intra-cellular ion
concentrations, can locate and quantify cell membrane damage in tissues. Gregory
Karczmar, PhD, and Martin J. Lipton, MD, are leading this MR effort, and MR
facilities are located within the emergency ward.

Positron emission tomography (PET) and single photoelectron emission computed
tomography (SPECT) are also being employed (Fig. 3) to map and monitor tissue
injury. Richard Reba, MD, Malcolm Cooper, MD, and Chin-Tu Chen, PhD, of the
University's Franklin Memorial Research Institute, have implemented protocols
for measuring tissue perfusion, muscle membrane integrity, and glucose
metabolism. Soon to be routinely performed at the bedside, these techniques
employ radiotracers to reflect physiological conditions including cellular
metabolism, blood flow, and cell membrane integrity.
Nerve injuries are practically unavoidable following electrical shock. Because
of the complex composition of nerve tissue, the pattern of injury that often
results from electrical shock is more complex than commonly used neurological
tests allow to detect. To more accurately describe the electrical nerve injury
we have adapted more sophisticated spectral analysis techniques. We have found
that these studies are very helpful in making diagnosis and planning therapy.
Another aspect of the multidisciplinary clinical research program is the
complete neuropsychologic, psychiatric, and social-emotional evaluation of the
patients. Kathleen Kelley, MD, Neil Pliskin, PhD, Joseph Fink, PhD, and Gregory
Meyer, PhD, from the Department of Psychiatry, have begun a longitudinal study
of acute psychiatric ET patients. Their assessments are integrated with findings
of the peripheral nervous system evaluation, in-depth chart review to clarify
the degree and functional consequences of CNS damage, its correlates, and
predisposing factors. The rigorous neuropsychological evaluation of electrical
injury patients admitted in the program has provided important insight into
effective strategies for rehabilitation of patients with CNS injury. The first
article by N. Pliskin et al describing neuropsychological symptom presentation
after electrical injury was published in 1998 in the Journal of Trauma (8). To
understand the risk factors for development a psychiatric disorder following
electrical injury (such as depression or posttraumatic stress disorder), Dr.
Kathleen Kelley and Tatiana Tkachenko, MA, PhD, began to analyse which injury
circumstances are statistically associated with the increased likelihood of
subsequent emotional illness (9), the information that will allow to develop
more effective early intervention strategies to prevent or mitigate psychiatric
pathology.
