Specific morphological changes may be absent in some cases of electrocution shocked by the voltage of 220 V or lower. In this study, we attempted to demonstrate that the anterior wrist and medial malleolus were the optimal sites with promising and significant changes in electric death through the hand-to-foot circuit pathway. We established an electric shock rat model and observed histopathologic changes in the anterior wrist and medial malleolus. The results showed that the current intensities in the left anterior wrist and right medial malleolus were remarkably higher than those in the other sites, and the nuclei long/short (L/S) axis ratios of the arterial endotheliocyte and the skeletal muscle cell in these two areas were significantly higher than those in other parts of the body...

BACKGROUND: About 4% of glenohumeral dislocations are posterior and only 1% is associated with fracture of the humeral head. Most frequent causes are high energy traumas, seizures and electrocution. The fracture and the posterior dislocation, associated with the trauma and capsular lesion can cause an important vascular damage of the humeral head. METHODS: We describe 5 cases of posterior fracture-dislocation of the shoulder that required open reduction and internal fixation treated using double approach: posterior approach for reduction humeral head and eventually bone and capsular posterior repair and anterior approach for osteosynthesis...

BACKGROUND: Reliable quantification of mosquito host-seeking behaviours is required to determine the efficacy of vector control methods. For malaria, the gold standard approach remains the risky human landing catch (HLC). Here compare the performance of an improved prototype of the mosquito electrocuting grid trap (MET) as a safer alternative with HLC for measuring malaria vector behaviour in Dar es Salaam, Tanzania. METHODS: Mosquito trapping was conducted at three sites within Dar es Salaam representing a range of urbanicity over a 7-month period (December 2012-July 2013, 168 sampling nights)...

Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was performed to map elements in thin formalin-fixed paraffin-embedded tissue sections of two forensic cases with firearm and electrocution injuries, respectively. In both cases, histological examination of the wounded tissue regions revealed the presence of exogenous aggregates that may be interpreted as metallic depositions. The use of imaging LA-ICP-MS allowed us to unambiguously determine the elemental composition of the observed aggregates assisting the pathologist in case assessments...

INTRODUCTION: While generally reducing morbidity and mortality, electrical weapons have risks associated with their usage, including eye injuries and falls. With sufficient probe spread, an uncontrolled fall to the ground typically occurs along with the possibility of a fatal brain injury. METHODS: We analyzed possible risk factors including running and elevated surfaces with established head-injury criteria to estimate the risk of brain injury. We searched for cases of arrest-related or in-custody death, with TASER(®) electrical weapon usage where fall-induced injuries might have contributed to the death...

Electrical shock can result in neurological complications, involving both peripheral and central nervous systems, which may present immediately or later on. High-voltage electrical injuries are uncommonly reported and may predispose to both immediate and delayed neurologic complications. We report the case of a 68-year-old man who experienced a high-voltage electrocution injury, subsequently developed bulbar dysfunction and spontaneously recovered. We describe the development of bulbar palsy following a significant electrical injury, which showed no evidence of this on magnetic resonance imaging...

Electrocution cases reported in the literature were mainly caused by low-voltage alternating current, with few cases associated with high-voltage direct current. In this article, we report the case of a 48-year-old woman who unexpectedly and suddenly died in the wild because of electric shock by a high-voltage direct current while hunting. The postmortem inspection found a suspected current mark on her right upper thigh, and histological examination of the suspected current mark revealed a slight elongation of the epidermal cell nuclei and separation of the corneous layer...

BACKGROUND: New sampling tools are needed for collecting exophilic malaria mosquitoes in sub-Saharan Africa to monitor the impact of vector control interventions. The OviART gravid trap and squares of electrocuting nets (e-nets) were recently developed under semi-field conditions for collecting oviposition site seeking Anopheles gambiae (sensu stricto) (s.s.). This study was designed to evaluate the efficacy of these traps for sampling malaria vectors under field conditions. METHODS: Prior to field testing, two modifications to the prototype OviART gravid trap were evaluated by (i) increasing the surface area and volume of water in the artificial pond which forms part of the trap, and (ii) increasing the strength of the suction fan...

Decades after the problem was first identified, power line electrocution continues to be a cause of avian mortality. Currently, several federal laws protect eagles and other migratory birds, meaning that utility companies may be liable for electrocution-related deaths. Veterinarians and veterinary pathologists called upon to diagnose and treat electrocuted birds should keep this in mind when conducting clinical and postmortem examinations. This review details necropsy findings and methods used to diagnose electrocution...

When skin is subjected to water temperatures gradually rising from moderate to critical ranges for a prolonged period of time, the resulting scalds will initially present as reddening, followed by blistering and at last by full-thickness burns. On changing from second- to third-degree burn, the blisters stop to become enlarged and solidify due to heat-induced coagulation necrosis. Such gradually intensifying tissue damage results in multiple firm skin blisters together with third-degree burn of the affected area...

The current observation of deaths by electrocution, both for domestic and work-related accidents as well as those in other contexts, has deepened the scope of investigation into electric marks, especially from the histological point of view. This is one of the few investigation tools that may lead to the diagnosis of death by electrocution in this distinct area, bearing in mind the diagnostic difficulties that this type of fatality presents. Our attention has been placed on the phenomenon of metallization. In particular, we focused on using the Timm's method [1] to locate the copper deposits...

BACKGROUND: Photography is an integral component of the international travel experience. Self-photography is becoming a mainstream behaviour in society and it has implications for the practice of travel medicine. Travellers who take selfies, including with the use of selfie sticks, may be subject to traumatic injuries associated with this activity. This review article is the first in the medical literature to address this emerging phenomenon. METHODS: Articles indexed on PubMed and Scopus databases through 2015 were retrieved, using the search terms 'travel', combined with 'selfie', 'self-photography', 'smartphone', 'mobile phone' and 'social media'...

Although cardiac injury is known to be the leading cause of death in electrocution, the differential diagnosis can be challenging in forensic practice since the exact mechanism is poorly understood and there is lack of reliable markers. Thus, death due to electrocution may be classified as a negative autopsy. The serum levels of and myocardial immunostaining loss for cardiac troponins and heart-type fatty acid binding protein (H-FABP) are highly sensitive and specific biomarkers of ischemic myocardial damage and may have a diagnostic value in determining the myocardial injury or the cause of death due to electrocution...

BACKGROUND: On-going malaria transmission is increasingly mediated by outdoor-biting vectors, especially where indoor insecticidal interventions such as long-lasting insecticide treated nets (LLINs) are widespread. Often, the vectors are also physiologically resistant to insecticides, presenting major obstacles for elimination. We tested a combination of electrocuting grids with synthetic odours as an alternative killing mechanism against outdoor-biting mosquitoes. METHODS: An odour-baited device, the Mosquito Landing Box (MLB), was improved by fitting it with low-cost electrocuting grids to instantly kill mosquitoes attracted to the odour lure, and automated photo switch to activate attractant-dispensing and mosquito-killing systems between dusk and dawn...

BACKGROUND: Bilateral posterior fracture-dislocation of the shoulders is an uncommon complication of grand mal seizures. We report a case of bilateral posterior dislocation of the shoulders with proximal humeral fractures following epileptic seizures. A posterior fracture-dislocation of the shoulder is very rare and can be caused by epileptic seizures, trauma, electrocution or electroconvulsive therapy. CASE PRESENTATION: A 62-year-old Sri Lankan male was admitted to our medical unit following four repeated generalized tonic-clonic convulsions, each lasting for several minutes...
