Type of strabismus and changes to fusion measures

Assessing the range of vergence provides information about the patient’s ability to maintain the binocular vision. Disparity vergence measurements should be used to quantify control of an underlying eye misalignment. In the presence of a manifest deviation the testing is performed by first compensating the angle of deviation to determine prognosis. Type of deviation: a) in an exophoria there is an increase in the fast fusional convergence while in an esophoric deviation there is an increase in reflex fusional divergence to attain binocular single vision; b) convergence fusion amplitudes have been found to correlate with control of the exodeviation; c) there is a greater BO range for esos and greater BI range for exos.

Climate changes influence in occupational exposure to fungi and mycotoxins

Climate changes and their effects on fungal distribution and activity are aspects of concern regarding the human exposure to mycotoxins. An exhaustive search was made for papers available in scientific databases reposrting the influence that climate cchange has on fungi and mycotoxins. Also a review regarding fungal burden, collected between 2010 and 2015 in different settings, was done to support the discussion about future fungi and mycotoxins ocuupational exposure. A. flavus complex, E. graminerarum complex and F. verticilliodes were the most reported to be influenced by climate changes. We noted also that the analyzed Portuguese settings presented already an occupational problem due to their fungal burden. It will be important to know future climate changes to select what complexes/species and strains, and consequently the mycotoxins, we should consider as indicators of an occupational problem. In addition, epidemiologic studies are needed to increase knowledge about potential health effects related with the exposure to both risk factors.
