An unusual case of lightning injury: a melted silver necklace causing a full thickness linear burn

Lightning-induced pacing system malfunction: a case report

BACKGROUND

Atmospheric electrical discharge is an extremely powerful natural phenomenon which can have dangerous and lethal effects on the human body. However, there is no evidence to indicate whether and, if so, to what extent the electric current travelling through the body can affect proper pacemaker function.

CASE SUMMARY

An 80-year-old patient admitted to emergency department after being struck by a lightning bolt while riding a bike. The patient had a DDD pacemaker implanted 4 years prior to the incident. The ECG on admission depicted pacemaker spikes and native sinus rhythm at 50-60 b.p.m. On the 3rd day after admission the patient developed recurrent pacing-induced tachycardia. Pacemaker interrogation showed high pacing thresholds (failure to pace in the atrial channel). When the patient's condition stabilized she was transferred to the tertiary hospital for transcutaneous lead extraction. The extracted pacing system was sent to Biotronik for thorough evaluation.

DISCUSSION

Injuries due to a lightning strike are considered a rare occurrence but being struck by lightning with a pacemaker or an ICD is even less common. In the present case, the cause of cardiac arrhythmia was most probably electrical burn at the endocardial-electrode interface and a sudden elevation of the pacing threshold leading to transient pacing failure in both PM channels. To the best of our knowledge, in this case presentation we first described permanent lightning-induced pacemaker dysfunction.

Lightning Burns and Electrical Trauma in a Couple Simultaneously Struck by Lightning

More people are struck and killed by lightning each year in Florida than any other state in the United States. This report discusses a couple that was simultaneously struck by lightning while walking arm-in-arm. Both patients presented with characteristic lightning burns and were admitted for hemodynamic monitoring, serum labs, and observation and were subsequently discharged home. Despite the superficial appearance of lightning burns, serious internal electrical injuries are common. Therefore, lightning strike victims should be admitted and evaluated for cardiac arrhythmias, renal injury, and neurological sequelae.

Right Hemispheric Leukoencephalopathy as an Incidental Finding Following a Lightning Strike

BACKGROUND

Lightning injuries may produce a variety of medical conditions, and specific neurological complications have been identified, with the character of immediate aftershock effects or even long-term consequences.

AIM

The authors describe the incidental finding following a routine unenhanced brain MRI performed to a young female patient, suffering from a headache.

CASE REPORT

Diffuse white matter changes with the character of a leukoencephalopathy were seen, which strictly interested only the right cerebral hemisphere. The parents referred that she suffered from an indoor lightning strike at age of seven months, although she survived with almost no external burns or signs, and recovered uneventfully at that time. A discussion over the effects of electrocution and lightning strike on the human body in general, and over the nervous system, is made. Particular attention must be shown when making the differential diagnosis of leukoencephalopathies with a strictly one-hemisphere extension since several other conditions might resemble each other under the radiological aspect, here including brain viral infections, genetic disorders, and so on.

CONCLUSION

The particularity of the long-term aftershock effects of the lightning strike on the central nervous system raise again the necessity of collecting data and duly reporting every electrical accident, lightning events included.

Wilderness Medical Society practice guidelines for the prevention and treatment of lightning injuries: 2014 update

To provide guidance to clinicians about best practices, the Wilderness Medical Society (WMS) convened an expert panel to develop evidence-based guidelines for the treatment and prevention of lightning injuries. These guidelines include a review of the epidemiology of lightning and recommendations for the prevention of lightning strikes, along with treatment recommendations organized by organ system. Recommendations are graded on the basis of the quality of supporting evidence according to criteria put forth by the American College of Chest Physicians. This is an updated version of the original WMS Practice Guidelines for Prevention and Treatment of Lightning Injuries published in Wilderness & Environmental Medicine 2012;23(3):260-269.

Jewelry-induced diseases of the head and neck

The desire to modify a person's outer appearance is a phenomenon that can be traced back to the beginning of humankind. Body modifications have been practiced among all cultures around the globe to differing extents. The authors present medical complications through jewelry in a series of 35 consecutive patients. Patient charts were evaluated for age, gender, type and sequelae of injury, complications, and treatment results. The male-to-female ratio was 1:2.2. Most of the recorded complications were related to the new vogue of piercing, with the ear affected most commonly. Usually the complications were minor; however, 2 patients sustained disfiguring damage to their auricular cartilage as a result of high ear piercing, a child nearly asphyxiated on an aspirated earring, and 2 patients experienced severe dysphagia as a result of tongue piercing. The most severe complication was a lethal strangulation injury in a female patient whose necklace got trapped in the headrest of her car seat during a front-end collision.

An unusual case of lightning strike: full-thickness burns of the cranial bones

An unusual full-thickness burn of the scalp and cranial bones due to a lightning strike is reported. A thick nylon cover protected the head from the direct effects of the lightning injury, but heated water over the thick nylon cover caused full-thickness burn of the scalp and cranial bones. The relevant literature has been reviewed.
