“…Primeau et al (1995) and Barrash et al (1996) point out that the cognitive complaints after EI resemble those in mild to moderate traumatic brain injury. However, it seems that the level of problems after EI can be hard to predict (Andrews 2012;Primeau et al 1995) and EI symptoms may occur or worsen after a delay (Bailey et al 2008). In the previously mentioned study by Pliskin et al (1998), the self-reported cognitive symptoms were more pronounced in the post-acute phase than in the acute phase after the accident.…”

“…If an EI victim does not present clear tissue damage, monitoring or follow-ups are uncommon. Andrews (2012) points out that psychological disability may be the biggest problem for an EI patient. While physical disabilities are often accommodated in a rehabilitation process after EI, cognitive and psychological problems can be a challenge for successful return to work (Stergiou-Kita et al 2014a, b;Theman et al 2008).…”

“…Being the victim of an occupational (or any) accident can be traumatic and lead to increased psychological problems (Chin et al 2017;Lin et al 2014) and this is evidently the case also for electrical accidents Piotrowski et al 2014;Pliskin et al 1998;Ramati et al 2009). Andrews (2012) indicates that psychological disability may be the biggest problem for an EI patient. In Pliskin et al (1998), approximately half of the EI patients reported anxiety and depressed mood.…”

Purpose The purpose was to examine long-term consequences of exposure to electrical current passing through the body. We investigated (1) whether electricians after having experienced an electrical accident report more cognitive problems and lower mental wellbeing and (2) have objectively verifiable reduced cognitive function; and (3) which circumstances at the time of the accident affect long-term subjective cognitive function and mental wellbeing? Methods A survey of male electricians who had experienced electrical accidents (n = 510) and a clinical study in a subsample (n = 23) who reported residual health problems was carried out. Both groups were examined regarding subjective cognitive function (Euroquest-9) and mental wellbeing (Symptom Checklist-90 subscales). The clinical study included neuropsychological tests of memory, attention, spatial function, and premorbid intellectual capacity. A matched control group was retrieved from reference data. Results The survey participants reported more cognitive problems and lower mental wellbeing than referents. Of the examined circumstances, having experienced mortal fear at the time of the accident and health complaints, especially mental symptoms, for > 1 week after the accident were the most significant risk factors for later subjective cognitive problems and lower mental wellbeing. The only statistically significant difference in neuropsychological tests was better performance in part of the memory tests by the clinical study group compared to the control group. Conclusions The participants reported more cognitive problems and lower mental wellbeing than referents, but no long-term objective cognitive dysfunction was detected. Emotional response at the time of the accident and health complaints in the aftermath of the accident may constitute important indications for medical and psychological follow-ups.

High-voltage electrical injuries are a devastating form of trauma often treated in burn centers. Examining superficial wounds alone may lead to an inaccurate assessment of local, regional, and systemic severity of injury. In this work, the neurovasculature at sites regionally distinct from the contact wound were assessed for cellular pathology. Nine male Sprague-Dawley rats subjected to 1000 V direct-current shocks were separated into three groups: high-shock (>10-second contact), low-shock (<4-second contact), and control. Injury video was captured with a forward-looking infrared camera, and a thermal excitation analysis was performed. The neurovascular bundles from the iliofemoral region to the distal posterior tibial region were dissected from the hind limbs of the shocked animals and stained by immunohistochemistry for antibodies specific to apoptosis (APO) 1, caspase-3, activating transcription factor 3, high-mobility group box-1, granulocyte-macrophage colony-stimulating factor and interleukin-6. Real-time reverse-transcription polymerase chain reaction was used to quantify differential transcript levels of superoxide dismutases 1, 2, and 3 and heat-shock protein 70 from peripheral blood mononuclear cells and liver tissue. Finally, a protein array was used to identify key inflammatory cytokines in blood plasma. Significant dose-dependent trends were identified in apoptotic markers as well as inflammatory markers in both arterial and nerve tissues. Although arterial tissue exhibited a gradual decline in these markers proximally from the wound site, nerve tissue maintained a constant level at every location. Transcript analysis revealed an up-regulation of extracellular superoxide dismutase, and down-regulation of heat-shock protein 70, whereas plasma inflammatory cytokine levels indicated no significant changes. Thermal excitation analysis revealed a linear temperature increase, with a dose-dependent thermal maximum. In this study the authors have shown that neurovascular APO and inflammation are present at locations extremely proximal to electrical injury contact sites and this appears to be dose-dependent. Nerve tissue APO and inflammation may extend farther proximally than the iliofemoral region, and multiple proapoptotic mechanisms may be activated. No systemic inflammatory response was indicated in this study.
