Eosinophilic meningitis (EoM) is an acute disease that affects the central nervous
system. It is primarily caused by infection with the nematode Angiostrongylus
cantonensis. This infection was previously restricted to certain Asian
countries and the Pacific Islands, but it was first reported in Brazil in 2007. Since
then, intermediate and definitive hosts infected with A. cantonensis
have been identified within the urban areas of many states in Brazil,
including those in the northern, northeastern, southeastern and southern regions. The
goals of this review are to draw the attention of the medical community and health
centres to the emergence of EoM in Brazil, to compile information about several
aspects of the human infection and mode of transmission and to provide a short
protocol of procedures for the diagnosis of this disease.
All program directors and department chairs who participated in the survey are aware of this technology with the exception of one department chair. More than half of the program directors reported that they have incorporated this technology in their curricula compared to only 12% of department chairs. Currently, only 10% or less of complete denture cases are processed using the CAD/CAM technology, at either the post- or predoctoral levels. Both groups reported that the main use of this technology is for the fabrication of denture bases and for processing dentures including the try-in step. The majority of respondents in both groups indicated they plan to add digital denture fabrication into their curricula within the next 1 to 4 years.
The metal impression copings were more accurate than plastic copings when using the Straumann system, and there was no difference between metal and plastic copings for the Nobel Replace system. The system-by-screw location was not conclusive, showing no correlation within each system.
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.
