Although solvent mixture concentrations and noise levels were low, our results demonstrate that there may be a concurrent ototoxicity and neurotoxicity condition and emphasize the importance of including BAEP analysis for comprehensive assessments. Future studies that include otoacoustic emissions assessments to monitor cochlear function and central auditory processing tests are imperative.
This article describes the current situation of occupational health (OH) in Mexico, including socioeconomic context, legislation, health system, and educative and investigative resources, as well as the practice of OH. Workplace accidents per 100 workers decreased from 7.23 to 2.3 workers in 20 years; deaths decreased from 1.68 to 0.9 per 10,000 workers, while the occupational disease rate increased from 0.6 to 1 per 10,000 workers. This can be interpreted as an improvement in preventive measures as well as problems of recognition and registry. In Mexico OH faces challenges that range from needs for professional training and performance to needs for development of legal measures, coordination, information, and research.
All blood cytological components analyzed demonstrated mild changes, potentially associated with exposure to the mixture of BTX. Macrocytosis could constitute an early manifestation worthy for surveillance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
