Bilateral maculopathy following electrical burn: case report / Maculopatia bilateral após queimadura elétrica: relato de caso

CONTEXT: Electrical burns are an important etiology in dealing with patients suffering from burns. In situations of extensive deep lesions of multiple organs and systems affecting young and economically active people, there is a need for expensive multidisciplinary treatment, with a high socioeconomic cost for the community. Among the permanent injuries that explain this high cost, eye injuries stand out, since they are widely disabling. Although rare, lesions of the posterior segment of the eye are associated with higher incidence of major sequelae, and thus deserve special attention for dissemination and discussion of the few cases observed. CASE REPORT: The authors report the case of a patient who suffered high-voltage electrical burns and presented bilateral maculopathy, which evolved with a need for a surgical approach to repair retinal detachment and permanent low visual acuity. CONCLUSION: This report highlights the rarity of the etiology of maculopathy and the need for campaigns for prevention not only of burns in general, but also especially of electrical burns. .

CONTEXTO: As queimaduras elétricas representam etiologia importante na abordagem de pacientes vítimas de queimaduras. Lesões extensas e profundas de múltiplos órgãos e sistemas e o acometimento de população jovem economicamente ativa apontam para a necessidade de tratamento multidisciplinar dispendioso, com alto custo socioeconômico para as comunidades. Dentre as lesões permanentes que justificam esse alto custo, as oculares têm local de destaque, porque são amplamente incapacitantes. Embora raras, as lesões do segmento posterior do olho estão associadas a maior incidência de sequelas importantes, merecendo atenção especial para divulgação e discussão dos poucos casos observados. RELATO DE CASO: Os autores relatam o caso de paciente vítima de queimadura elétrica com fio de alta voltagem que apresentou maculopatia bilateral, evoluindo com necessidade de abordagem cirúrgica para correção de descolamento de retina e baixa acuidade visual permanente. CONCLUSÃO: Este relato destaca a raridade da etiologia da maculopatia e a necessidade de campanhas de prevenção não só das queimaduras em geral, mas especialmente das queimaduras elétricas. .

Ritmo nodal secundario a descarga eléctrica de alto voltaje: Report of one case / Transient high frequency nodal rhythm after a high voltage electric shock

Electrical shock can cause a direct myocardial damage and different types of arrhythmias, which are uncommon and occur more often when there is a high voltage exposure. We report a 19-year-old male that received a high voltage shock, falling thereafter from an altitude of four meters. On admission to the emergency room, he had second and third degree burns in the right hand and the left thigh. The electrocardiogram showed a nodal rhythm of 72 beats per minute. After four hours of monitoring, sinus rhythm returned spontaneously.

Changes of CK-MB and HSP 60 in electrical-injuried rats / 法医学杂志

OBJECTIVE@#To investigate the changes of creatine kinase-MB (CK-MB) and heat shock protein 60 (HSP 60) in rats without electric marks after electric injury, to identify the relationship of the CK-MB, HSP 60 and the time of electric injuries, and to evaluate the damage to cells after electric injury.@*METHODS@#The animal model of electric injury without electric marks was established by alternating current (voltage 110 V). Automatic biochemistry analyzer was used to detect the serum CK-MB and immunohistochemical staining technology was used to analyze the tissues of myocardium and left lobe of liver.@*RESULTS@#The amount of serum CK-MB was increased when the rats were injuried, and reached the peak at 30min. Then the amount of CK-MB began to decrease and showed a slight downward trend in 3-5 h after electric injury, and leveled off at 6 h. Immunohistochemistry staining also showed the changes of HSP 60 of rats' myocardial cells and hepatic cells regularly after electric injury.@*CONCLUSION@#The regular changes of serum CK-MB and tissular HSP 60 in rats can be used to diagnosis electric injury and assess the injury of internal organs after the electric injury without electric marks.

Esophageal stricture following electrical injury.

Esophageal injury resulting from electrical shock is rare. Stricture of esophagus following external electrical injury has not been reported yet. We report a 24-year-old electric lineman who developed esophageal stricture following external electrical shock. He responded to dilatation with Savary-Gilliard dilators.

Electrical Injury As A Possible Cause of Sick Sinus Syndrome

Electrical injury is a serious public health problem. Heart is one of the most frequently affected organs. Electrical injury can cause life-threatening cardiac complications such as asystole, ventricular fibrillation, and myocardial rupture. In this case report, we present a 20-yr-old male patient with sick sinus syndrome that developed years after electrical injury.

Acute transverse myelitis following electrical injury: a short report.

We report a 30 years lady who developed transverse myelitis following an accidental electric shock and later recovered completely.

Trauma eléctrico: fisiopatología y resucitación / Electric trauma: physiopathology and resuscitation

La atención del paciente que sufre una injuria eléctrica es generalmente poco conocida por el médico general, probablemente debido a su relativa poco frecuencia, excepto en centros especializados a tal fin o en instituciones en que este fenómeno traumático es más frecuente (ej.: trabajadores de red de distribución eléctrica). Se describe la epidemiología del trauma eléctrico, su atención inicial y forma de presentación en el terreno, como también los tipos de lesiones que pueden aparecer luego de la injuria, por lo general de manifestación tardía con posibles secuelas severas a largo plazo. El seguimiento atento de estos pacientes a corto y mediano plazo es la clave para prevenir daños mayores.

Comprometimento pulmonar em trauma eletrico: relato de caso / Pulmonary lesion in eletric injury: case report

Trauma eletricos severos constituem cerca de 5 por cento das admissoes em Unidades de Queimados. O acometimento visceral pela corrente eletrica apresenta grande morbidade e mortalidade. A presenca de lesoes viscerais sem continuidade com lesao de partes moles e pouco referida, porem de extrema gravidade, principalmente pela dificuldade diagnostica que apresenta. Lesoes cardiacas tem sido mais frequentemente relatadas, ocorrendo em 10 a 25 por cento dos pacientes, consistinto basicamente em arritmias e disturbios de conducao, consequentes a espasmos coronarios ou lesao muscular difusa pela corrente...

Injuria miocárdica asociada a corriente eléctrica domiciliaria / Myocardial injury caused by domiciliary electric current

La injuria eléctrica del miocardio ha sido descrita en diversas instancias. La injuria eléctrica por rayos y de alto voltaje, son sabidas causas de arritmias severas, isquemia miocárdica transitoria, así como cambios electrocardiográficos y enzimáticos simulando un infarto de miocardio. La corriente eléctrica alterna de bajo voltaje (110 a 380V) usada en el equipamiento eléctrico domiciliario, ha sido reportada como causante de muerte súbita, usualmente como resultado de fibrilación ventricular. La naturaleza de la injuria eléctrica miocárdica es una intriga. La rareza del evento y la escasez de datos experimentales relevantes, hacen la tarea de revelar los mecanismos patogénicos de la injuria miocárdica eléctrica muy dificultosa. Describiremos los hallazgos electrocardiográficos inusuales, así como el curso clínico de un paciente que presentó un infarto de miocardio luego de una injuria eléctrica de bajo voltaje. Realizamos una profunda revisión bibliográfica sobre la injuria eléctrica de bajo voltaje causando infarto de miocardio. En conclusión, la similitud de la injuria miocárdica con la injuria de repercusión, así como la ausencia de trombos coronarios o ateroesclerosis significativa en la autopsia, hacen el espasmo coronario como probable causa de necrosis miocárdica en la electrocución

Electrocardiographic manifestations following household electric current injury.

Electrocardiographic monitoring of a 24 year old male, who sustained household electric current injury, showed low voltage ECG complexes, varying degrees of atrioventricular (AV) blocks, and ventricular fibrillation. The low voltage ECG complexes and varying AV blocks disappeared spontaneously and ventricular fibrillation reverted to normal after cardioversion.
