Abstract: Thoughts and moods are the result of biological processes; disordered thoughts and moods may be the result of disordered biological processes. As brain dysfunction can manifest with emotional symptoms or behavioral signs, the etiology of some mental health afflictions and some abnormal conduct is pathophysiological rather than pathopsychological. Various studies confirm that some chemical toxicants which modify brain physiology have the potential to affect mood, cognitive function, and to provoke socially undesirable outcomes. With pervasive concern about myriad chemical agents in the environment and resultant toxicant bioaccumulation, human exposure assessment has become a clinically relevant area of medical investigation. Adverse exposure and toxicant body burden should routinely be explored as an etiological determinant in assorted health afflictions including disordered thinking, moods, and behavior. The impact of toxicant bioaccumulation in a patient with neuropsychiatric symptoms is presented for consideration as an example of the potential benefit of recognizing and implementing exposure assessment. 相似文献

Abstract: Santeria and Palo Mayombe are syncretic religions created in the New World based upon African religious beliefs combined with Christianity. The main worship of Palo Mayombe involves religious receptacles that may contain earth, sticks, varied artifacts, and animal and human remains. Due to the use of human and nonhuman remains, discovery of these items often leads to involvement by the police due to a concern of homicide. We review in detail the medical examiner records of two of these ritualistic cases including the autopsy, anthropology, police, and investigators' reports. For the human remains, careful consideration of the context in which the remains were recovered, their state of preservation, and the associated artifacts (e.g., beads and mercury) are important in determining the appropriate level of forensic significance. Anthropological examination with particular attention to taphonomic characteristics also may help determine the origin and forensic significance. 相似文献

Abstract — This is the second paper of a series following a study carried out in the Brazilian Amazon region of peasant livelihoods, their current character and problems of sustainability. It analyses how different people might be affected by environmental degradation in the region by looking at their social and economic activities, the degree of dependency on wild resources, land ownership and the social relations underpinning the structure of the labour force. The study covers three districts within the ecological system of terra firme. Extractivist activities generate income and contribute considerably to food supplies throughout the year. Access to these resources is not generally tied to ownership. Environmental degradation may reduce the future availability of resources or, alternatively, attack health directly. Peasants exposure to these risks is assessed and the long-term sustainability of their livelihoods examined. Possible planning solutions to problems are presented and the more recent debate on the creation of conservation units (SNUC) in Brazil is discussed. 相似文献
