Power-line grids are increasingly expanding worldwide, as well as their negative impacts on avifauna, namely the direct mortality through collision and electrocution, the reduction of breeding performance, and the barrier effect. On the other hand, some bird species can apparently benefit from the presence of power lines, for example perching for hunting purposes or nesting on electricity towers. In this perspective essay, we reviewed the scientific literature on both costs and benefits for avifauna coexisting with power lines...

INTRODUCTION: Deaths from electricity, generally, do not have specific findings at the autopsy. The diagnosis is commonly based on the circumstances of the death and the morphologic findings, above all the current mark. Yet, the skin injury due to an electrocution and other kinds of thermal injuries often cannot be differentiated with certainty. Therefore, there is a great interest in finding specific markers of electrocution. The search for the metallization of the skin through Scanning Electron Microscope equipped with Energy Dispersive X-Ray Spectroscopy (EDS) probe is of special importance in order to achieve a definite diagnosis in case of suspected electrocution...

Diagnosis of death by electrocution may be difficult when electric marking is not visible or unclear. Accordingly, the body of a man who appeared to have died from accidental electrocution was carefully forensically analysed. Macroscopic and microscopic analysis of the current mark was carried out using a variable-pressure scanning electron microscope equipped with energy dispersive X-ray microanalyser to highlight skin metallisation, indicating the presence of iron and zinc. The histological findings of electrocution myocardial damage were supported by the results of biochemical analysis which demonstrated the creatine kinase-MB and cardiac troponin I elevation...

The interaction between wildlife and power lines has collateral effects that include wildfires and Carbon Dioxide (CO2) emissions. However, currently available information is scarce and so new approaches are needed to increase our understanding of this issue. Here, we present the first analysis of wildfires and their incidence as a result of this interaction in Spain during the period 2000-2012. Amongst the 2788 Power-Line Mediated Wildfires (PLMW recorded) during this period, 30 records of Fauna Mediated Wildfires (FMW) were found, with an average affected vegetation cover of 9...

Temminck's ground pangolin is the only pangolin present in South Africa. It is a myrmecophagous mammal with a bipedal gait. The thoracic limbs are used to break open ant nests, dig for food, and expand previously occupied burrows. This study describes the osteology and radiological anatomy of the thoracic limbs of this threatened species. Thoracic limbs from four Temminck's ground pangolins, which succumbed from electrocution or natural causes, were digitally radiographed in situ. The individual bones were then cleaned, described and digitally radiographed...

BACKGROUND: The UK military was continuously engaged in armed conflict in Iraq and Afghanistan between 2003 and 2014, resulting in 629 UK fatalities. Traumatic cardiac arrest (TCA) is a precursor to traumatic death, but data on military outcomes are limited. In order to better inform military treatment protocols, the aim of this study was to define the epidemiology of TCA in the military population with a particular focus on survival rates and injury patterns. METHODS: A retrospective database analysis of the UK Joint Theatre Trauma Registry was undertaken...

Electrocution fatality cases are difficult to investigate. High-voltage electrocution burns resemble burns caused by other sources, especially if the person survives for few days. In that case, circumstantial evidence if correlated with the autopsy findings helps in determining the cause and manner of death. In addition, the crime scene findings also help to explain the pattern of injuries observed at autopsy. A farmer came in contact with a high-voltage transmission wire and sustained superficial to deep burns over his body...

INTRODUCTION: Death from electrocution is rare and generally an accidental occurrence. In contrast to civilian patterns of electrocution injury, the military work environment suffers from a greater percentage of fatal high-voltage electrocutions. This study compared U.S. and international electrocution case fatality rates to rates among deployed military personnel presenting for care at expeditionary medical care facilities. We also sought to identify potential risk factors for fatal electrocution injury among deployed military personnel...

Broilers in the United States are typically electrically stunned using low voltage-high frequency (12-38 V, ≥400 Hz) DC or AC water bath stunners. In the European Union, however, broilers are required to be electrocuted using high voltage-low frequency (50-150 V, 50-350 Hz) AC. Low voltage stunned broilers regain consciousness in the absence of bleeding. In contrast, high voltage stunned broilers die due to induction of cardiac fibrillation. For birds stunned with low voltage systems, concerns have been raised regarding animal welfare during bleeding...

BACKGROUND: Plasmodium knowlesi is found in macaques and is the only major zoonotic malaria to affect humans. Transmission of P. knowlesi between people and macaques depends on the host species preferences and feeding behavior of mosquito vectors. However, these behaviours are difficult to measure due to the lack of standardized methods for sampling potential vectors attracted to different host species. This study evaluated electrocuting net traps as a safe, standardised method for sampling P...

Shoulders are the most common major joint to become disarticulated, and shoulder dislocation is a frequent patient presentation to the ED. Bilateral shoulder dislocations, however, are rare and typically caused by seizure activity or electrocution. Posterior disarticulation is most common following seizure activity. This article describes an adolescent girl who dislocated both shoulders anteriorly following seizure activity.

In forensic practice, determination of electrocution as a cause of death usually depends on the conventional histological examination of electrical mark in the body skin, but the limitation of this method includes subjective bias by different forensic pathologists, especially for identifying suspicious electrical mark. The aim of our work is to introduce Fourier transform infrared (FTIR) spectroscopy in combination with chemometrics as a complementary tool for providing an relatively objective diagnosis. The results of principle component analysis (PCA) showed that there were significant differences of protein structural profile between electrical mark and normal skin in terms of α-helix, antiparallel β-sheet and β-sheet content...

Cadaveric spasm causes instantaneous rigor without preceding post-mortem flaccidity. The precise pathophysiological basis of this phenomenon is still unknown. We report a case of accidental electrocution where the deceased was found dead with a metallic water supply pipe of a motor booster pump firmly gripped in his hand. In this report, we review the literature and consider the mechanisms that may cause this phenomenon.

Presented are 2 cases of death from pulmonary alveolar proteinosis (PAP). Within the past 2 years, there have been 2 cases of rare nonneoplastic lung disease that consists of the filling of the alveoli of the lung by a periodic acid-Schiff stain-positive lipoproteinaceous material. This condition bears a certain resemblance to interstitial lung disease and/or Pneumocystitis jirovecci infection of the lungs. The presented cases were clinically diagnosed as interstitial lung disease. In the first case presented, the decedent was admitted to hospital with diagnosis of pneumonia but died in hospital despite observation and treatment...
