    ABSTRACT: OBJECTIVE: To describe and review autonomic complications of lightning strike. METHODS: Case report and laboratory data including autonomic function tests in a subject who was struck by lightning. RESULTS: A 24-year-old man was struck by lightning. Following that, he developed dysautonomia, with persistent inappropriate sinus tachycardia and autonomic storms, as well as posttraumatic stress disorder (PTSD) and functional neurologic problems. INTERPRETATION: The combination of persistent sinus tachycardia and episodic exacerbations associated with hypertension, diaphoresis, and agitation was highly suggestive of a central hyperadrenergic state with superimposed autonomic storms. Whether the additional PTSD and functional neurologic deficits were due to a direct effect of the lightning strike on the central nervous system or a secondary response is open to speculation.

    ABSTRACT: The electric flash burns are a common cause of accident at workplace, especially among electricians. The aim of this study is to determine the parts of the body most often burned by the flash, to define the usual course and finally to give some simple rules of care and prevention. This is a retrospective, observational and descriptive study including all patients treated at the University Hospital of Tours for electrical flash burns between 1 January 2003 and 01 January 2013. A collection of medical and socio-economic data was achieved. We present 3 cases of patients hospitalized in our department. Thirty-three patients were included. In our series, all hospitalized patients were men. The average age was 43.2years (range 18 to 82years). In 81% of cases, the burn was due to a low voltage source, in 19% of cases to a high voltage source. It was an accident at workplace for 71% of patients, of whom 67% were electricians. The average total burned area was 9,52% (from 1.5% to 24%). The main locations included the face (86%), upper limbs (86%) and hands (86%). Medical treatment has healed 95% of patients. A surgical procedure was required in 5% of cases. A post-traumatic stress was found in 41% of patients. Outpatient treatment was performed in 36% of cases. Flash burns remain a common cause of hospitalization. Screening for hearing and eye disorders, a post-traumatic stress, as well as the prescription of early physiotherapy for burned hands are important components of their management. Following simple rules of prevention would limit their morbidity.

    ABSTRACT: Aim: This article provides and reviews hypotheses to help explain the poorly understood phenomenon of delayed neurological injury following lightning or electrical injury. Method: A review of extant literature provides a starting point to integrate what is already known in an attempt to provide new hypotheses for this phenomenon, as well as to discuss existing hypotheses. Result: The author proposes two theories which stem from the literature on the damaging effects of oxidative stress, and also reviews an existing hypothesis, the electroporation hypothesis. The former two theories can account for delayed damage which is either of vascular or nonvascular origin. The electroporation hypothesis can explain changes both in cases where there is cellular loss as well as cases where there only appears to be change in function after lightning or electrical injury. Conclusion: Although all theories discussed are speculative, the formation of hypotheses is always a starting point in the scientific process. In cases where there is delayed neurological damage with a vascular origin, it is possible that free radicals resulting from oxidative stress may gradually damage spinal vascular endothelial cells, cutting off blood supply, and ending in death of spinal neurons. When the delayed condition is demyelination without vascular damage, it is possible that the free radicals from oxidative stress are formed directly from the lipids found in abundance in myelin cells. The electroporation hypothesis, the formation of additional pores in neurons, may best explain immediate or progressive changes in structure and function after lightning or electrical injury.
