ABSTRACT
High levels of scatter radiation in catheterization laboratories may lead to posterior subcapsular opacities in the lens of the staff. The international Retrospective Evaluation of Lens Injuries and Dose (RELID) was performed in Argentina for the first time in 2010 in the context of the congress of the Latin American Society of Interventional Cardiology (SOLACI) and recently, in 2014, was carried out for the second time (SOLACI-CACI 2014). The 2014 study included 115 participants: interventional cardiologists, technicians and nurses. Posterior subcapsular lens changes typical of ionizing radiation exposure were found in 91.5% of interventional cardiologists, in 77% of technicians and in 100% of nurses, according to the Merriam-Focht scale. This RELID study (Argentina 2014) has particular importance since it allowed the follow-up of 10 professionals evaluated in 2010. The results obtained in the study population highlight the importance of the availability and proper use of the elements of radiation protection, as well as staff training.

Visually evoked potentials to patterned stimuli were recorded from tennis players, rowers and non-athlete control subjects. Each group consisted of 12 males and 12 females of similar age. Tennis players showed shorter P100 latencies compared to those of control subjects and rowers. This difference exists, in the same range, both in the male and in the females. The analysis of covariance and multiple linear regressions show that these shorter latencies cannot be explained by head circumference or by height. The hypothesis of a relationship between these shorter latencies and the specific qualities of racket players is suggested. A second experiment with squash players seems to confirm these first results.
