Ethical problems in radiology: radiological consumerism
No full textOne of the causes of the increasing request for radiological examinations occurring in all economically developed countries is the active role played by the patient-consumer. Consumerism places the radiologist in an ethical dilemma, between the principle of autonomy on the one hand and the ethical principles of beneficence, nonmaleficence and justice on the other. The choice made by radiologists in moral dilemmas is inspired by an adherence to moral principles, which in Italy and elsewhere refer to the Judaeo-Christian tradition or to neo-Darwinian relativism. Whatever the choice, the radiologist is bound to adhere to that choice and to provide the patient with all the relevant information regarding his or her state of health
[The role of "competent physician" for prevention of accidents at work]
No full textUsing at best the professional and legal tools at his/her disposal, the "competent physician" can have a relevant role in reducing accidents in the workplace. In assessing the worker's suitability to specific tasks, the competent physician checks the presence of pathologies or functional impairments of organs or apparatuses that can be an additional risk for the occurrence of accidents at work. The activity aimed to preventing accidents at work translates also in taking part in the planning and implementation of information activities and workers' training within the company. The various risk factors inherent in the workplace and so-called "human factors" can interact in a negative way to the point of becoming a cause of accidents. The human variables of accident risk at the industrial, occupational and even individual level, may be numerous. In this paper we shall review these important aspects and attempt to clarify the role that can be played by the competent physician in the prevention of accidents at work

Toxicological Effects of Titanium Dioxide Nanoparticles: A Review of In Vivo Studies
Full text linkThe essence of nanotechnology is the production of nanoparticles (NPs) with unique physicochemical properties allowing worldwide application in new structures, materials, and devices. The consequently increasing human exposure to NPs has raised concerns regarding their health and safety profiles. Titanium dioxide (TiO2) has been reported to induce adverse pulmonary responses in exposed animals. However, the potential more dangerous biological activities of TiO2 NPs compared to their fine-sized counterparts are not fully understood. Therefore, this work is aimed to provide a comprehensive evaluation of the toxic effects induced by TiO2 NPs in in vivo experiments. It is intended to deeply understand the toxicological behaviour of TiO2 NPs and to predict potential human health effects. Moreover, it may be an instrument to extrapolate relevant data for human risk evaluation and management and to identify those critical aspects that deserve great attention in future population and epidemiologic research
