Contrast sensitivity measurement accurately evaluates the sensitivity of all human visual channels, even in a more detailed manner than simple acuity measures can. This is a study of visual contrast sensitivity in a series of subjects occupationally exposed to organic solvents. Contrast sensitivity was measured for 42 printers and 28 age-stratified controls(More)
Tobacco smoke is the single most important modifiable risk factor for coronary diseases and the leading preventable cause of death in the US. While the effect of cigarette smoking on the progression of atherosclerotic diseases is established and well studied, the role of cigarette smoking on cardiac arrhythmia is less clearly defined. In fact the(More)
The aim of this study was to examine whether signs of neurotoxic influence on the autonomic nervous system, after lengthy occupational lead exposure, could be revealed by appropriate cardiac rhythm analysis. A total of 109 male lead-exposed workers and 27 controls were examined in a cross-sectional study. In addition, 17 lead-exposed participants were(More)
Augmented Reality (AR) uses computer-generated virtual information to enhance the user’s information access. While numerous previous studies have demonstrated the large potential of AR to improve industrial processes by enhancing product quality and reducing production times it is still unclear if and how long term usage of such AR technology produces(More)
To verify occupational neurotoxic effects it will be necessary to enlist the help of clinical psychologists and psychiatrists. However, no unified professional test battery exists to date. 119 healthy workers (26 lead-exposed, 45 exposed to mixed organic solvents, and 48 controls) were tested using uniformly standardised psychological and psychiatric(More)
PURPOSE Interest in diseases of the nervous system resulting from occupational exposure to mixed organic solvents has greatly increased. The aim of our study was to identify preclinical effects of low-level chronic solvent exposure on the central nervous system in car painters by assessing their cognitive performance. METHODS This psychological study(More)
INTRODUCTION PTSD is associated with comprehensive disruption of several neurobiological regulation mechanisms and with a disruption in the parasympathetic-sympathetic balance. This can be measured with the heart rate variability (HRV). METHODS A systematic review in PubMed using the keywords "hrv" or "heart rate variability" and "PTSD" or "posttraumatic(More)
The situation of exposure in a copper works facility in Germany enabled early lead-induced neurotoxic effects to be investigated in the workers. The aim of the investigation was to study the long-term effects of small doses of lead on psychometric/psychophysiological performance of workers. The study involved 70 male lead exposed workers and 27 male(More)
The aim of the study was the determination of the influence of chronic occupational exposure to organic solvent mixtures on the contrast sensitivity (CS) of silk-screen printers. Contrast sensitivity was measured for 28 matched (age, sex) pairs of silk-screen printers and controls using the Vision Contrast Test System - VCTS 6500 chart. The duration of(More)
