Lightning safety guidelines.

On average, lightning causes more casualties annually in the United States than any other storm-related phenomenon except floods. Although 90% of those injured survive, they may have permanent sequelae and disability. Many of these people incur injuries or are killed by lightning because of misinformation and inappropriate behavior during thunderstorms. A few simple precautions can reduce lightning injury risk. To standardize recommended actions during thunderstorms, the Lightning Safety Group (LSG), composed of lightning experts from many lightning-related backgrounds, met at the American Meteorological Society meeting Phoenix, AZ, in January 1998 to collectively address personal lightning safety. This paper is a summary of the recommendations developed by the LSG.

Lightning accident with eight victims: case report and brief review of the literature.

A case of a lightning accident with eight victims is presented. The patients presented with typical injuries, such as cardiocirculatory arrest, apnea, burns, lightning paralysis, and rupture of internal organs. Two of three patients with cardiocirculatory arrest were successfully resuscitated. A brief description of the spectrum of typical lightning injuries, as well as the recommended therapy concepts, are given.

Electrical injury and amyotrophic lateral sclerosis: a systematic review of the literature.

Electrical injury may act as a potential precipitating or risk factor for amyotrophic lateral sclerosis (ALS). A systematic review of the literature was undertaken to assess the relationship between electrical injury and the development of ALS. Information for the review was obtained using five medical databases, and from manual searching of individual papers. Patients presenting with a neurological syndrome after electrical injury, including lightning, were included and classified into four categories: ALS; progressive upper motor neurone (UMN) syndrome; progressive lower motor neurone (LMN) syndrome; and non-progressive syndrome. Linear regression and chi2 testing were used for analysis of the data. 96 individuals, comprising 44 with ALS, 1 with a progressive UMN syndrome, 7 with a progressive LMN syndrome and 44 with a non-progressive syndrome, were identified from 31 papers with publication dates between 1906 and 2002. The median interval between electrical injury and disease onset was 2.25 years for all progressive syndromes and just over 1 week for the non-progressive syndrome. The more severe the shock (excluding lightning), the more likely individuals were to have a non-progressive motor syndrome. A non-progressive spinal cord syndrome is associated with more severe electrical injury. Overall, the evidence reviewed does not support a causal relationship between ALS and electric shock.

Amyotrophic Lateral Sclerosis↗

A case of takotsubo-shaped hypokinesis of the left ventricle caused by a lightning strike.

A 62-year-old woman was struck by lightning while on a mountain and fortunately did not suffer burns or unconsciousness. She stayed at a mountain lodge overnight and was taken to our hospital by helicopter the next day. Upon admission, electrocardiography showed ST segment elevation indicating acute lateral myocardial infarction, and echocardiography showed takotsubo-shaped hypokinesis of the left ventricle indicating an apical aneurysm. Her serum escaped enzyme levels were increased, as is typical in cases of myocardial infarction, however, she did not complain of cardiac symptoms. Coronary arteriography performed 4 days after admission showed a normal coronary artery while left ventriculography showed apical akinesia. An echocardiogram obtained 2 days later showed resolution of the LV wall motion abnormality. This is the first reported case of takotsubo cardiomyopathy caused by lightning. Takotsubo-shaped hypokinesis is not described as a complication of lightning-induced cardiac injury and its pathogenesis remains controversial.

Medical mountain rescue in the Mont-Blanc massif.

Because of its peculiar geographic location beneath Mont-Blanc, the Chamonix Hospital plays an important role in the management of mountaineering- and skiing-related traumatic injuries. The authors, thanks to the study of 5200 mountain rescue medical reports, set out to explain the different aspects of this activity: epidemiology, specific equipment, care in the field, reception and primary survey, dispatching, common therapeutic attitudes, progress, and results. In the dangerous environment of the high mountains, emphasis is put on the physicians' experience, allowing an early evacuation in the best conditions to the hospital. Diagnosis at the scene of the accident is very basic, and the initial treatment is based on immobilization, analgesia, and sedating. In the case of resuscitation, only the vital maneuvers are performed; these actions are carried on during the short flight and improved in the crash rooms. Finally, different specific pathologies are mentioned, including cold- or heat-related injuries, exhaustion, lightning strikes, and mountain sickness.

Lightning Strike and Electric Shock Survivors, International.

Prior to1989 no known support group existed for victims of lightning or electrical shock injury and their families. A lightning strike survivor of twenty years, Steve Marshburn, recognized the need both from his personal experience and after meeting two other survivors. With his wife and psychologist, he formed Lightning Strike and Electric Shock Survivors International. The organization has grown nearly one hundredfold from the thirteen who attended the first annual meeting. The support group serves people from around the world, has produced a number of publications, participated in research about these injuries and has become active in prevention activities. This paper will describe some of the factors that have led to such success for the organization.

Neurorehabilitation of cerebral disorders following lightning and electrical trauma.

The most devastating casualties in lightning and electrical trauma patients are the result of lesions of the nervous system, and especially lesions of the brain. The brain injuries can be divided into three categories: global dysfunction; focal brain injuries; and behavioral-cognitive sequelae without gross physical signs. Lightning injuries are usually the result of outdoor sports and leisure activities. Most electrical trauma cases are the result of workplace accidents. Rehabilitation planning should begin early after the incident and often needs to be continued for a long time. The goal of the rehabilitation team is to maximize functional return in patients with deficits related to brain lesions. The neurorehabilitation team includes the neurorehabilitation physician, physical therapists, occupational therapists, psychologists, speech therapists, and case managers.

Atmospheric flash injuries in roe deer (Capreolus capreolus).

The pathological and histopathological examination of two female roe deer found dead after a severe thunderstorm is described. One of the two roe deer was killed by a direct hit of atmospheric flash, while the other animal, lying 1.5 m from the first one, died as a consequence of ground current strike. The major part of the coat and skin of the animal that was killed by a direct hit was covered with scorched streaks. The trachea and bronchi of both animals contained a considerable amount of aspirated light-red foam. Necropsy revealed diffuse haemorrhages over the epicardium of the right atrium with a diameter of 1 millimetre. The liver and the kidney exhibited severe congestion.
