Injuries from lightning strikes are an infrequent occurrence, and are only rarely noted to involve pregnant victims. Only 13 cases of lightning strike in pregnancy have been previously described in the medical literature, along with 7 additional cases discovered within news media reports. This case report presents a novel case of lightning-associated injury in a patient in the third trimester of pregnancy, resulting in fetal ischemic brain injury and long-term morbidity, and reviews the mechanics of lightning strikes along with common injury patterns of which emergency providers should be aware...

Electrical injuries in animals occur most often accidentally. They comprise contact to various forms of currents, including alternating, rotary, or direct currents. Depending on various parameters of the current (including the type of circuit, voltage, current and duration of exposure) and conditions of the animal (such as wet or dry hair coat and pathway of current through the body), lesions may be absent or may include early or localized development of rigor mortis, signs of acute circulatory failure, or severe thermoelectrical burns...

According to data from the National Oceanic and Atmospheric Administration,in the years from 1959 to 1994, lightning was responsible for more than 3000 deaths and nearly 10,000 casualties. The most important characteristic features of lightning injuries are multisystem involvement and widely variable severity. Lightning strikes are primarily a neurologic injury that affects all 3 components of the nervous system: central, autonomic,and peripheral. Neurologic complications of lightning strikes vary from transient benign symptoms to permanent disability...

INTRODUCTION: Every year, 240,000 people are struck by lightning worldwide, causing injuries leading to significant handicaps. Most of the symptoms involve brain lesions; neuromuscular sequelae and myelopathy are less common. OBSERVATIONS: We describe five cases of patients struck by lightning with various clinical presentations. The first patient presented painful paresthesias in both upper limbs that disappeared 18 months later; the injury was a plexopathy. The second patient developed proximal weakness in the upper-left limb due to a myopathy...

Several cases of motor neuron disease (MND) after electric injury have been reported in the last number of years, but the relationship between electric injury and MND remains controversial. Herein we report the case of a 60-year-old man who developed a MND following an electrical trauma. In the case presented here, the onset of disease at the site of lightning strike and the short interval of time between the electrical injury and the clinical onset of MND raise the possibility of considering electrical shock as a trigger factor for MND...

INTRODUCTION: Electrocution is the cause of a large number of accidents and, of these, a considerable percentage result in death. Several factors affect the severity and distribution of the injuries. It is known that for low voltages the characteristics of alternating current make it three times more dangerous than continuous current. The high percentage of neurological sequelae can be accounted for by the fact that nerves are the tissue with the lowest resistance in the body and electricity tends to follow the path that offers the least resistance...

Proverbs tend to have meanings that are true both literally and figuratively (i.e., Lightning really doesn't strike the same place twice). Consequently, discourse contexts that invite a literal reading of a proverb should provide more conceptual overlap with the proverb, resulting in more rapid processing, than will contexts biased towards a non-literal reading. Despite this, previous research has failed to find the predicted processing advantage in reading times for familiar proverbs when presented in a literally biasing context...

While spinal cord injuries caused by lightning strike or electrical shock are rare, their clinical manifestations pose unique challenges to the clinician who must anticipate the interaction of multiple system involvement with the altered physiology of spinal cord injury. Spinal cord damage may be secondary to the direct effects of electrical current passing through neural tissue producing immediate or delayed impairment. Alternatively, lightning strike and electrical shock may lead to spinal cord damage due to the secondary consequences of injury such as spinal fractures sustained after a fall...

BACKGROUND: Brain death is the irreversible cessation of intracranial neurologic function and is considered as the person's death. The objective of this study was to describe the characteristics of pediatric donors in the Hospital Central de Asturias from October 1995 to October 2002. METHODS: We performed a retrospective and descriptive study of the dead children who were potential donors in the pediatric intensive care unit (PICU). RESULTS: Of 43 dead children, 15 (34...

PRIMARY OBJECTIVE: This paper examined the use of an atypical neuroleptic medication, risperidone, in reducing the excessive motor activity of an adolescent with an anoxic brain injury following cardiac arrest from a lightning strike. Lower extremity restlessness caused the patient to develop skin breakdown and interfered with healing of existing burns. RESEARCH DESIGN: Single-blind, placebo-controlled single-subject experimental design. EXPERIMENTAL INTERVENTION: Escalating doses of risperidone up to 1 mg and in combination with methylphenidate (10 mg) and amantidine (100 mg)...

OBJECTIVE: To report the clinical and mitochondrial genetic analyses of two families, each of which carries both the 11778 and 14484 Leber hereditary optic neuropathy (LHON) mutations in mitochondrial DNA. METHODS: In addition to detailed clinical histories, the complete sequence of the mitochondrial DNA (mtDNA) from each family was determined. RESULTS: A small Australian LHON family (Vic20) and a family from the United States carry the 11778 and 14484 LHON mutations...

The present study attempts to better understand the mechanism of injuries associated with direct lightning strikes. We reviewed the records of 256 individuals struck by lightning between 1965 and 1999, including 56 people who were killed. Basal skull fracture, intracranial haemorrhage, pulmonary haemorrhage, or solid organ rupture was suspected in three men who died. Generally these lesions have been attributed to current flow or falling after being struck. However, examination of surface injuries sustained suggested that the true cause was concussion secondary to blast injury resulting from vaporization of water on the body surface by a surface flashover spark...

Two previously healthy 14-year-old horses developed right-sided unilateral vestibular signs after they had possibly been struck by lightning. Repeated radiographic and endoscopic evaluations did not reveal any significant changes. A brainstem auditory evoked response test indicated a subtle left to right interaural latency difference of waves I, III and V in the more severely affected pony, but its central conduction time remained normal.

Exposure to electrical current via industrial or residential accidents or lightning strikes is a serious and growing concern in today's medical community. The sequelae that result are referred to as electrical injury (EI) or lightning injury (LI). The relevant principles in electricity are reviewed with particular attention given to their damaging capabilities on the body. Specific neuropsychological, psychiatric, and neurological signs and symptoms as well as objective measures of psychological and neuropsychological functioning and brain imaging in victims of EI and LI, are reviewed from past research...

We report an extraordinary event of a lightning strike to the head of a helmeted bicyclist that occurred under fair weather conditions with a cloudless sky. The patient sustained a cardiac arrest and hypoxic encephalopathy with residual neurologic impairment. With the availability of highly developed meteorologic equipment, we were able to determine that the lightning "bolt from the blue" probably originated in a thunderstorm that was about 16 km away and obscured by the mountains.

When a person is struck by lightning a spectrum of neurologic damage can result. Approximately one third of the strikes prove to be fatal. The possibility of damage to the CNS relates to the type of lightning injury (direct strike, stride potential, or side flash), the intensity and duration of the current, the pathway of the current within the body, and secondary injuries to brain either from cardiac arrest and hypoxia or from physical trauma. Direct strikes to the head have a high degree of fatality and often result in petechiae or larger brain hemorrhages...

An analysis of 45 victims of fatal lighting strike revealed the incident occurred most frequently in the early afternoon during midsummer in a field of one form or another. The scene of death, damage to clothing, and alterations of metallic objects on the victim are described. A terminal cardiac rhythm of ventricular fibrilation was recorded in half for whom data were available, and asystole was found in 40%. All but four had cutaneous injuries, and nearly one-third had pathognomonic patterns of erythematous arborization...
