Abstract Monkey mortality in Costa Rica is due, in most cases, to anthropogenic factors, such as deforestation, forest fragmentation, lack of tree connectivity, and tourism development in most coastal areas. The latter factor has caused the death of at least 450 monkeys per year due to electrocution, as a result of the increase in electrical wiring that has arisen in the different regions with urban development. Faced with this threat, proposals have been developed to avoid the danger, such as the construction of appropriate passage infrastructure for monkeys, the placement of insulated wiring, and the protection of electrical transformers. Using the morphometric measurements of the four species of monkeys native to Costa Rica (Alouatta palliata, Ateles geoffroyi, Saimiri oerstedii, and Cebus imitator), a model of safe and functional aerial passages or bridges for them was designed, the foundations of which are discussed in this article.

Resumen La mortalidad de los monos en Costa Rica se debe, en la mayoría de los casos, a factores antropogénicos, como la deforestación, la fragmentación de los bosques, la falta de conectividad arbórea y el desarrollo turístico en la mayoría de las zonas costeras. Este último factor ha provocado la muerte de al menos 450 monos por año debido a la electrocución, a raíz del aumento del cableado eléctrico que ha surgido en las diferentes regiones con desarrollo urbanístico. Ante esta amenaza se han elaborado propuestas para evitar el peligro, como la construcción de infraestructura de paso apropiada para los monos, la colocación de cableado aislado y la protección de los transformadores eléctricos. Utilizando las medidas morfométricas de las cuatro especies de monos nativas de Costa Rica (Alouatta palliata, Ateles geoffroyi, Saimiri oerstedii y Cebus imitator), se diseñó un modelo de pasos aéreos o puentes seguros y funcionales para ellos, cuyos fundamentos se discuten en el presente artículo.

Resumen: Introducción: la luxofractura glenohumeral posterior (LFGHP) es una lesión poco frecuente. Puede ser secundaria a una crisis convulsiva, casos de electrocución, o por traumatismo directo. Su diagnóstico suele ser tardío, lo que aumenta la tasa de complicaciones y secuelas. Caso clínico: paciente de sexo masculino de 52 años, trasladado a centro de alta complejidad por convulsión tónico-clónica y LFGHP derecha. En el estudio inicial con radiografías se confirma lesión de hombro derecho y se diagnostica luxación glenohumeral posterior simple de hombro izquierdo no pesquisada previamente. Se complementa estudio con tomografía computarizada (TC) de ambos hombros, observándose una LFGHP bilateral, lo que demuestra agravamiento intrahospitalario de la lesión del hombro izquierdo. Se realiza reducción abierta y osteosíntesis con placa bloqueada bilateral en un tiempo. El hombro izquierdo requirió dos reintervenciones, una por falla de osteosíntesis y otra para liberación articular. Dos años después del procedimiento el paciente evoluciona satisfactoriamente con 5% en la escala Quick DASH y un puntaje de 72 y 76 en la escala de Constant en el hombro derecho e izquierdo, respectivamente. Conclusión: la LFGHP es una lesión poco frecuente que requiere un alto índice de sospecha para evitar el retraso diagnóstico y la aparición de secuelas. En casos de convulsión se debe sospechar compromiso bilateral. Con un tratamiento quirúrgico oportuno se pueden obtener resultados satisfactorios y reintegración del paciente a sus actividades habituales.

Abstract: Introduction: posterior glenohumeral fracture dislocation (PGHFD) is a rare injury. It may present secondary to a seizure, electrocution or due to direct trauma. It is usually missed, and late diagnosis is common which increases the rate of complications and sequalae. Case report: 52 year old male, transferred to a reference trauma center due to a tonic-clonic seizure and a right PGHFD. Upon admission radiographs are requested and right shoulder injury is confirmed. Additionally, a simple left posterior glenohumeral dislocation (that was missed in the initial assessment of the patient) is observed. A computed tomography (CT) scan is obtained for both shoulders to plan surgery. The CT scan showed a bilateral PGHFD with severe comminution in the left shoulder, showing considerable worsening of the left shoulder since admission. Open reduction and bilateral locked plate osteosynthesis were performed in a one stage surgery. At two years follow up the patient evolved favorably with a Quick DASH score of 5% and a CONSTANT score of 72 and 76 for his right and left shoulder, respectively. Conclusion: PGHFD is an infrequent injury, which requires a high level of suspicion to avoid diagnostic delay and prevent complications and sequelae. Bilateral cases may be seen in cases of seizure. With prompt surgical treatment, satisfactory results can be achieved with a complete return to normal activities.

Resumo A eletrocussão é tema pouco relatado para as grandes araras. O objetivo deste trabalho foi analisar a mortalidade das araras por eletrocussão na área urbana de Campo Grande, Mato Grosso do Sul. Entre 2011 e 2020 foram registradas 59 araras mortas por eletrocussão, tendo como vítimas duas espécies: Ara ararauna (Linnaeus, 1758) e a Ara chloropterus (Gray, 1859). A. ararauna foi a espécie com maior incidência, com 48 aves mortas, seguida da A. chloropterus, com 11 indivíduos. A eletrocussão foi um importante fator de perda das grandes araras no ecossistema urbano. O tamanho corporal, a envergadura das asas e o comportamento das araras, bem como a localização e proximidade das estruturas elétricas com os recursos alimentares e de nidificação favoreceram as chances de eletrocussão. Logo, é necessário desenvolver medidas de mitigação para conciliar o desenvolvimento sustentável de uma cidade de porte médio como Campo Grande com a conservação da biodiversidade.

Abstract Electrocution is a theme that has been rarely reported for large macaws. The objective of this study was to analyze mortality of macaws due to electrocution in an urban area of Campo Grande, Mato Grosso do Sul. Between 2011 and 2020, 59 macaws were registered as having died through electrocution, and these were from two species: Ara ararauna (Linnaeus, 1758) and Ara chloropterus (Gray, 1859). A. ararauna had the largest number of deaths registered (48), and A. chloropterus had 11 individuals. Electrocution was shown to be an important factor for the loss of large macaws in this urban environment. Body size, wingspan, and behavior of the macaws, as well as location and proximity of food resources and nests to electrical structures, were shown to increase the probability of electrocution. These results demonstrate the need to develop mitigation measures to reconcile the sustainable development of a medium-sized city such as Campo Grande with biodiversity conservation.

Resumen La electrocución es tema poco reportada en los guacamayos. El objetivo de este trabajo fue analizar la mortalidad de guacamayos en el área urbana de Campo Grande, Mato Grosso do Sul. Entre 2011 y 2020 fueron registrados 598 guacamayos muertos por electrocución teniendo como víctimas, dos espécies: Ara ararauna (Linnaeus, 1758) y Ara chloropterus (Gray, 1859). A. ararauna fue la especie con más incidencia, con 48 aves muertas, seguida de A. chloropterus , con 11 individuos. La electrocución es la causa importante de pérdida para los guacamayos en el ecosistema urbano. El tamaño corporal, la envergadura de las alas y el comportamiento urbano de los guacamayos, bien como la localización y la proximidad de los tendidos eléctricos con los recursos alimenticios y de nidificación favorecido las posibilidades de electrocución. Por lo tanto, es necesario desarrollar medidas de mitigación conciliar el desarrollo sustentable de una ciudad mediana como Campo Grande com la conservación de la biodiversidad.

Resumen Introducción: Aunque los pasos de fauna han demostrado ser exitosos para reducir las colisiones entre vehículos y vida silvestre y vincular el hábitat fragmentado, su capacidad para prevenir electrocuciones de la vida silvestre arbórea no se ha examinado a fondo. Objetivo: Evaluar la efectividad de los puentes aéreos de cuerdas para restaurar la conectividad del hábitat de las especies arbóreas en Manuel Antonio, Costa Rica y al mismo tiempo prevenir las electrocuciones al determinar 1) qué especies están usando los puentes de cuerda y 2) si la vida silvestre prefiere usar puentes de cuerda en lugar de otras estructuras peligrosas que cruzan las carreteras (como cables telefónicos, que frecuentemente están muy cerca de cables eléctricos). Métodos: De enero a mayo de 2016, se monitorearon nueve puentes de cuerda a lo largo de la carretera principal altamente transitada que se extiende desde Quepos a Manuel Antonio, Costa Rica, utilizando cámaras trampa y la observación directa en diez puentes de cuerda a lo largo de una carretera pavimentada más pequeña fuera de la carretera principal. Resultados: Se observaron un total de 11 especies utilizando los puentes y se presenciaron 1 540 cruces mediante cámaras trampa y observaciones (1 234 mediante cámaras trampa, 306 durante las observaciones). Los resultados de una prueba t pareada no mostraron diferencias significativas en el número promedio de individuos que cruzan la carretera a través de puentes de cuerda versus cables telefónicos, t (8) = 1.027, P = 0.334. Conclusiones: Los puentes de cuerdas son utilizados por una variedad de especies de vida silvestre arbóreas con un alto grado de frecuencia; sin embargo, debido al uso igualmente elevado de cables telefónicos por parte de la vida silvestre arbórea, se considera que son insuficientes para prevenir las electrocuciones de la vida silvestre por sí solas. Los puentes de cuerda deben instalarse junto con otros métodos para evitar electrocuciones, como cables eléctricos aislados, para facilitar el paso seguro de la vida silvestre por las carreteras.

Abstract Introduction: Although wildlife crossing structures have proven successful at reducing wildlife-vehicle collisions and linking fragmented habitat, their ability to prevent electrocutions of arboreal wildlife has not been closely examined. Objective: To evaluate the effectiveness of aerial rope bridges in restoring habitat connectivity for arboreal species in Manuel Antonio, Costa Rica, while preventing electrocutions by determining 1) what species are using the rope bridges and 2) whether wildlife prefer to use rope bridges instead of other hazardous structures that cross the roads (such as telephone cables, which are often in close proximity to electric wires). Methods: From January to May 2016, nine rope bridges along the highly-trafficked main road that extends from Quepos to Manuel Antonio, Costa Rica, were monitored using camera traps, and ten rope bridges were observed directly along a paved side road off the main road. Results: A total of 11 species were seen using the bridges, and 1 540 crossings were witnessed via camera traps and observations (1 234 via camera traps, 306 during observations). Results from a paired t-test showed no significant difference in the average number of individuals crossing the road via rope bridges versus telephone cables (t(8) = 1.027, P = 0.334). Conclusions: Rope bridges are used by a variety of arboreal wildlife species with a high degree of frequency; however, due to the equally high usage of telephone cables by arboreal wildlife, they are insufficient to prevent wildlife electrocutions on their own. Rope bridges should be installed in tandem with other methods to prevent electrocutions, such as insulating electric wires, to facilitate the safe passage of wildlife over roads.

Resumen Introducción: son pocos los datos documentados sobre los resultados de la reanimación cardiopulmonar en el paro cardiorrespiratorio extrahospitalario por causa de electrocución. El paro cardiorrespiratorio se produce cuando una descarga eléctrica interrumpe de forma abrupta la actividad eléctrica normal del corazón, lo que genera una electrocución y una alteración en los movimientos cardiacos y, por consiguiente, bombeo anormal de sangre y oxígeno a los tejidos. Ello constituye una emergencia clínica que puede ocasionar nefastas consecuencias de no tomarse medidas enérgicas e inmediatas. Presentación del caso: hombre con paro cardiorrespiratorio producido por electrocución y manejado en un ámbito extra-hospitalario, quien respondió con éxito a las maniobras aplicadas. Personal técnico y de salud iniciaron precozmente la reanimación cardiopulmonar y luego fue reforzada por personal médico, que aplicó desflbrilación en dos ocasiones con desflbrilador externo automático (DEA). Con ello se logró recuperar los signos vitales del paciente y trasladarlo a un centro asistencial para continuar su manejo intrahospitalario. Conclusión: la realización de una reanimación precoz y la desfibrilación de pacientes electrocutados, así como las medidas encaminadas a la protección del cerebro, son la norma prioritaria en la asistencia pre-hospitalaria de estos pacientes, quienes son potencialmente recuperables. Por tal razón, es importante que la comunidad, en general, esté preparada y que el personal de salud se reentrene en soporte vital básico, que incluye el manejo del DEA para dar oportunidad de sobrevivir a personas que sufran un paro cardiorrespiratorio extrahospitalario.

Abstract Introduction: There are few the documented data about the cardiopulmonary resuscitation results in the cardiorespiratory arrest extra-hospital due to the electrocution. The cardiorespiratory arrest occurs when the heart's normal electrical activity is abruptly interrupted by electric shocks generated by electrocution, causing the disturbance in the cardiac movements and, consequently, abnormal pumping of blood and oxygen to the tissues. The cardiorespiratory arrest due to electrocution is one clinic emergency that can cause disastrous consequences, if energetic measures are not taken immediately. Case presentation: A man with cardiorespiratory arrest produced by electrocution and managed in an extra-hospital area, who responded successfully to the maneuvers applied. The cardiopulmonary resus-citation maneuvers were precociously started by the health technical staff; next, reinforced by medical it, applying the defibrillation on two occasions, with external automatic defibrillator (AED), recovering the patient's vital signs and allowing his transfer to a healthcare center to continue in-hospital management. Conclusion: The performing of early resuscitation and defibrillation of electrocuted patients, as well as the measures aimed at protecting the brain, are the priority rules in the pre-hospital scene of these patients, who are potentially recoverable. For this reason, it is important that the community, in general, be ready, and the health staff gets trained in basic vital support that includes the management of AED to give the opportunity of surviving to people that suffer a cardiorespiratory arrest.

The electrocution of large birds such as eagles and vultures when making simultaneous contact between a phase conductor and the top of a pole on medium voltage woodpole distribution lines is addressed. System (phase-to-phase) voltages of 11 kV, 22 kV and 33 kV are covered. This phenomenon has been investigated by measurement of the resistance of poles used in the field, as well as measurement of the impedance of recently deceased birds. This has previously been used to compile a simple electrical model for 22 kV systems. This paper compiles a detailed model that is used to estimate the risk posed to large birds by this mode of electrocution for all three voltage levels. The results show that only a few scenarios exist whereby a bird may be at risk, which ties in with field experience. Details of how the wood and bird resistance was measured are also included, as are details of calculations performed.

ABSTRACT Primates are in imminent risk of extinction due to different types of anthropogenic activities. Mortality due to road accidents and electrocution from power lines are among the major direct anthropogenic threats to the survival of primates. We collected primate mortality data from 2015 to 2017 at Lawachara National Park and Satchari National Park in northeastern Bangladesh. We recorded 27 fatalities in five species of primates caused by road accidents (n = 15) and electrocution (n = 12). Most mortality records were for Trachypithecus phayrei (Blyth, 1847) (n = 8) while the lowest recorded mortality was for Macaca mulatta (Zimmermann, 1780) (n = 3). Ninety percent of primates in Bangladesh are threatened and populations are gradually declining. Our results suggest that roads and power supply lines are major sources of primate mortality that should be managed in these two forests. We strongly suggest avoiding construction of roads and power supply lines inside forests. Furthermore, control of the speed limit of vehicles inside the forests, use of insulated power lines, maintenance of natural canopy bridges and preparation of artificial canopy bridges are strongly recommended.

BACKGROUND. Electrocution as a cause of death has been discussed extensively in the international literature. However, research on this topic in South Africa (SA) is scarce. OBJECTIVES. To address the need for further research in this field and emphasise the necessity for preventive measures by determining the demographic and pathological profile of fatal electrocution cases seen in the Tygerberg Forensic Pathology Services, Western Cape Province, SA. METHODS. The study was a retrospective and descriptive case series of all the cases of death secondary to electrocution referred to the study facility from 1 January 2008 to 31 December 2012. RESULTS. A total of 39 cases were included. Ten victims (25.6%) were aged <13 years. The geographical area most affected by electrocution deaths was the informal settlement Khayelitsha (56.4% of cases). The primary injuries described were mainly burn wounds (34 cases, 87.2%) and abrasions (4 cases, 10.3%). Most injuries were to the upper limbs. Unfortunately, the results pertaining specifically to the pathology of electrical burn wounds were inconclusive. CONCLUSIONS. In view of discrepancies found in the reporting of electrical burn wounds, a standardised system for classifying these wounds is suggested. Although electrocution-related mortality is not a leading cause of death in high-prevalence areas, awareness should be raised.

Bilateral shoulder dislocations are usually of the posterior type, which is commonly associated with seizures, electrocution or electroconvulsive therapy. Bilateral anterior shoulder dislocations are very rare and usually result from significant trauma. Simple bilateral anterior shoulder dislocations without associated fracture are much rarer and not many cases have been reported in the literature. We present a traumatic bilateral simple anterior shoulder dislocation in a 24-year-old male without any features of ligamentous laxity, and review the international literature on simple bilateral anterior shoulder dislocations. From the review we conclude that seizures are as important an aetiology of simple bilateral anterior shoulder dislocation as is trauma. Moreover, this injury is not as rare as was considered in the past.

El trauma eléctrico es poco frecuente en la consulta pediátrica. Sólo corresponde al 1% de la lesiones por quemaduras, siendo más frecuente en niños menores de 6 años, varones, con capacidad de deambulación y exploración autónoma del entorno. El órgano blanco por excelencia de la corriente eléctrica son los nervios, por su baja resistencia. Esto condiciona las múltiples manifestaciones clínicas, en diversos tiempos, pudiendo ser causa de mortalidad, gran morbilidad y secuelas que ocasionan discapacidades con impacto sobre la calidad de la vida del individuo. Se reporta el caso de un lactante menor masculino con trauma por electrocución con neuropatía craneal y periférica, haciendo énfasis en los aspectos fisiopatogénicos, clínicos y paraclínicos de la lesión neurológica. Conclusión: La corriente eléctrica tiene como órgano blanco el sistema nervioso central. El trauma eléctrico tiene expresión clínica neurológica variable y puede dejar secuelas que modifican la calidad de vida del niño. Las estrategias de educación en prevención pueden disminuir la ocurrencia de estas lesiones.

Electrical trauma is rare in the pediatric clinic. Only 1% of injuries correspond to burns, these being more common in male infants and preschool children with sufficient mobility and autonomy to explore their environment. Nerves are the target organ of electric current , due to their low resistance. This determines multiple clinical manifestations and may be the cause of mortality, high morbidity and sequels that may cause disabilities which impact negatively the child’s quality of life. The case of a male infant with trauma by electrocution with cranial and peripheral neuropathy is reported, with particular emphasis on pathophysiological, clinical and paraclinical aspects of the neurological injury. Conclusion: Electric trauma has variable clinical neurological expressions and may cause severe sequels that affect the child’s quality of life. Educational strategies on prevention can reduce the occurrence of these external injuries.

In this work, a risk analysis for working with an analyzer for gamma cameras diagnostic was made. The method employed is based on determining the Hazard Rating Number (HRN). The results showed that the risks with higher value of HRN are electrocution with 100 and touch source container with hands with 75. These risks were classified as "Very High" and "High" respectively. The following risks were classified as "Important": Fall of the source container (HRN = 25), high dose of the sample in the container (HRN = 20) and fracture of glass detector (HRN = 30). The wrong shielding of the source container (HRN= 10) is a risk that was classified as "Low". Safety rules for use of the system are indicated. An action plan for risk management is also presented

Se realizó un estudio de los riesgos asociados al trabajo con un analizador para el diagnóstico de cámaras gamma. Para ello se utilizó el método Hazard Rating Number, el cual se basa en la determinación del número de riesgo. Los resultados mostraron que los riesgos con mayor HRN son por electrocución con un valor de 100 y por tocar el contenedor de la fuente con las manos, con 75. Estos riesgos se clasificaron como “Muy Alto” y “Alto” respectivamente. Como “Importante” se clasificaron los siguientes riesgos: caída del contenedor de la fuente (HRN = 25), dosis elevada de la muestra en el contenedor (HRN = 20) y fractura del cristal del detector (HRN = 30). El mal blindaje del contenedor de la fuente (HRN = 10) es un riesgo que se clasificó como “Bajo”. Se indican reglas de seguridad para uso del sistema. También se presenta un plan de acción para la gestión de los riesgos

Introduction: Electrocution is a frequent cause of traumatic death. It produces lesions and external signs that should be corroborated by microscopic findings. Objective: To correlate macroscopic findings with histopathologic results in electrocution deaths. Design: Descriptive, cross-sectional, correlational, retrospective study. Setting: Legal Medicine Institute-MP, Pathology Institute, Universidad Nacional Mayor de San Marcos, Lima, Peru. Material: Medicolegal necropsy reports. Results: From 116 cases, 8 were women and 108 males, mean age was 31.3 years. Twenty three per cent were electricians and 18% worked in construction. The incident occurred at labor center in 51%. Suicide accounted for two cases. Frequent macroscopic findings were general signs of choking, power input injuries, myocardial hemorrhage and subpleural petechiae in 73.3%. Microscopic alterations were skin coagulative necrosis in 87 cases, cerebral edema in 101, pulmonary hemorrhage in 83, acute myocardial infarction in 87, and acute tubular necrosis in 72 cases. A significant association between macroscopic and microscopic findings (0.592 V Cramer value; p <0.0001) was found. Conclusions: Most common macroscopic findings (lesion input, myocardial hemorrhage and subpleural petechiae) and most frequent microscopic findings (skin coagulative necrosis, acute myocardial infarction and acute tubular necrosis) related to electrocution seemed to be significantly associated.

Introducción: La electrocución es una causa de muerte de índole traumática y de alta mortalidad, que produce lesiones y signos externos que deben ser corroborados por hallazgos microscópicos. Objetivo: Correlacionar hallazgos macroscópicos con resultados histopatológicos en muertes por electrocución. Diseño: Descriptivo, transversal, correlacional, retrospectivo. Institución: Instituto Medicina Legal-MP, Instituto Patología, Universidad Nacional Mayor de San Marcos, Lima, Perú. Material: Informes de Necropsia Médico legal. Intervenciones: En la Morgue Central de Lima, en el periodo 2006-2011, se hizo búsqueda y análisis de información de electrocución. Principales medidas de resultados: Medida de tendencia central, frecuencias y porcentaje. Análisis de correlación. Resultados: De 116 casos, 108 varones y 8 mujeres, la media de edad fue 31,3 años, 23% fueron electricistas, 18% trabajaban en construcción. El hecho ocurrió en el centro de trabajo 51%, con etiología suicida en dos casos. Los hallazgos macroscópicos más frecuentes fueron signos generales de asfixia, lesiones por entrada de corriente eléctrica, hemorragia miocárdica y petequias subpleurales, en 73,3%. Las alteraciones microscópicas fueron: necrosis coagulativa en piel 87 casos, edema cerebral 101 casos, hemorragia pulmonar 83 casos, infarto agudo de miocardio 87 casos, necrosis tubular aguda 72 casos. Al correlacionar los hallazgos macroscópicos y microscópicos más frecuentes, encontramos una asociación significativa (valor V de Cramer de 0,592, p<0,0001). Conclusiones: Los hallazgos macroscópicos más frecuentes (lesión de entrada, hemorragia miocárdica y petequias subpleurales) y los hallazgos microscópicos más frecuentes (necrosis coagulativa en piel, infarto agudo de miocardio y necrosis tubular aguda) relacionados a electrocución parecen estar significativamente asociados.

Bilateral anterior dislocation of the glenohumeral (shoulder) joint is uncommon. Incidences of bilateral anterior fracture dislocation of the shoulder are relatively rare. About 16 cases are reported in the world literature. We report a case of bilateral anterior dislocation of the shoulder with bilateral avulsion fractures of the greater tuberosities of the humerus following seizure or convulsion due to electric shock.
