Medicolegal Implications of Fatalities Because of Entanglement in the Augers of Feed Mixer Wagons.

ABSTRACT: Feed mixer or total mixed ration mixer wagons are powerful agricultural machines used to shred and mix silage with other ingredients and deliver it direct to the feeding troughs on livestock farms. Fatalities involving these feed mixers may occur when operators become trapped in the augers or, less frequently, are crushed by moving wagons. Death can occur very rapidly because of dismemberment, multiple lesions, or crushing. The aim of this review is to focus on the diagnostic evaluations that need to be performed to confirm that the death was accidental and to exclude a hypothesis of murder or suicide. Forensic investigations in such cases must involve the detailed analysis of the death scene and the mechanical characteristics of the machinery with an accurate postmortem and toxicological examination.

Medicolegal Investigations Into Deaths Due to Crush Asphyxia After Tractor Side Rollovers.

Farm tractors are large, heavy, powerful vehicles with a high center of gravity. When driven carelessly on sloping, irregular, or slippery ground, tractors can overturn sideways and cause the death by crush asphyxia of the driver or passengers, especially if appropriate safety equipment is not fitted or used. The aim of this review is to focus on the diagnostic difficulties with which coroners and forensic pathologists have to cope when a confirmation of crush asphyxia after tractor side rollover is required by judicial authorities. Forensic investigations in such cases must involve the meticulous analysis of the death scene and the mechanical characteristics of the vehicle together with accurate postmortem and toxicological examination.

Urban green spaces activities: A preparatory groundwork for a safety management system.

INTRODUCTION: Urban green spaces works and maintenance are high-risk activities and usually represent possible sources of injuries. The management issues are complex and strongly influenced by companies' policies in terms of safety management and human factor. A high number of tasks-including protecting public health and safety and safe working procedures-need to be faced by professional arborists or gardeners. METHOD: The present paper provides a preparatory groundwork for modeling and describing the real risk levels during the abovementioned activities. The methodology represents a useful tool for decision making both for group leaders and safety coordinators. This goal is reached by collecting data emerging from several workplaces located in North East Italy regarding the frequency and severity of injuries. RESULTS: The preliminary results point out that the most frequent injuries in green maintenance activities are represented by cuts, contusions, and ocular lesions, but none of them have lead to particularly serious consequences for the operators; indeed, the high levels of severity are related to traumas, fractures, and acute lumbar herniated discs. The riskiest activities are related to pruning, especially using mobile elevating work platforms, and grass cutting, especially when operated in escarpments and banks. Workers' behavior and companies' safety policies are key elements for a correct safety management system.

Neck injury patterns resulting from the use of petrol and electric chainsaws in suicides. Report on two cases.

Suicides due to neck injuries caused by chainsaws are uncommon events. The cutting elements of petrol and electric chainsaws produce different features in lethal neck injuries. The accurate evaluation of the death scene, of the power and mechanical characteristics of the chainsaw and of wound morphology are all essential in distinguishing a case of suicide.

Air analysis in the assessment of fumonisin contamination risk in maize.

BACKGROUND: In maize-growing areas where fumonisin contamination is endemic, there is an urgent need for novel methods to assess the quality of grain lots before their delivery to common drying and storage collection centres. Aerobiological samples of fungal spores released during harvest were analysed to establish a relationship between fumonisin contamination and the abundance of pathogen propagules collected in the combine harvester using a cyclone and membrane filters. Filter-captured propagules were analysed by direct plating, immunoenzymatic assay of specific Fusarium extracellular polysaccharides and real time polymerase chain reaction of the extracted DNA using fum1, a gene involved in the biosynthesis of fumonisin, as a target. RESULTS: The results showed that time of harvest and environmental conditions strongly influenced the efficiency and performance of the collection system. The data obtained were informative in comparing individual samples collected under similar conditions. The immunoenzymatic assay provided the most reliable data, which improved the ability of a neural network to predict the fumonisin content of lots, when added to agronomic, environmental and phytosanitary data. CONCLUSION: This is the first attempt to evaluate the Fusarium propagules dispersed during harvesting as a predictive means to assess maize quality. A method based on cyclone/filter capture and immunological detection has been shown to be feasible and to have the potential for the development of a continuous monitoring system, but the prediction capabilities in the present implementation were limited.
