ABSTRACT

Hand injuries are a frequent occurrence and account for 41% of all occupational injuries. In general such accidents are the result of stress, inattention, tiredness, use of defective or poorly maintained machinery. However, artention must equally be directed at the large number of accidents occurring in leisure time activities since the inability to work due to a leisure time accident is similarly cost-intensive. Throughout Europe attempts have been made in the past 10 years to improve prevention. At the initiative of the Hand Trauma Committee (HTC) of FESSH prevention conferences were stated in 2009. These have in part reduced the number of hand injuries in -Europe. In Austria a special controlling committee was founded by the Austrian Workers' Compensation Board (AUVA) with the specific objective of reducing the number of hand injuries. Similarly the "Circle for Leisure Time Hand Injury Prevention" was created to specifically deal with hand injuries occurring during leisure time activities. Through the cooperation of these 2 committees and implementation of the thus decided measures, a reduction in the number of accidents involving the hand is to be expected with a concomitant reduction in the associated costs.

ABSTRACT

Benzo[a]pyrene, benzo[b]fluoroanthene and dibenzo[a,h]anthracene dissolved in a 1:2 mixture of dimethylsulphoxide (DMSO) and water were administered to two groups of female mice, each group containing 15 mice. The doses were administered orally (via gavage) at the respective rates of 1 and 100 micrograms kg-1 body weight five times per week for a period of 9 weeks. The influence of the polycyclic aromatic hydrocarbons (PAHs) was determined using the following methods: determination of DNA-PAH adducts, of chromosome injuries (micronucleus test), of induction of repair using the unscheduled DNA synthesis (UDS) test, and by examination of the DNA structure after nucleoid sedimentation. All the methods investigated provided evidence of a significant effect resulting from exposure to PAHs on the parameters examined. Following chronic exposure to PAHs, the formation of DNA-PAH adducts and injury to the genetic material, as well as the appearance of micronuclei (micronucleus test), the induction of unscheduled DNA synthesis (UDS test) and mutation of the DNA structure (nucleoid sedimentation), were demonstrated. The described methods therefore provide a means for the detection of genetic damage caused by PAH exposure in humans.

ABSTRACT

The hearing loss of 46,776 subjects exposed to hazardous impact or continuous noise was measured: 11% were exposed to impact noise (10.3% in men, 12.7% in women). Impact noise causes less hearing loss than continuous noise up to a noise emission level (NIL) of 115 dB(A). This result is still compatible with the concept of equivalent continuous A-weighted sound pressure level (LA,eq) and seems to be caused by the protective effect of the stapedius muscle. However, at emission levels higher than 115 dB(A), not covered by ISO 1999 prognosis, impact noise becomes more detrimental. This could be the effect of mechanical damage to the organ of Corti, as observed in animal experiments at sound pressure levels exceeding 114 dB(A). A diminishing protective function of the stapedius muscle could explain the more serious hearing impairment after long exposure to impact noise compared with shorter exposures to an equal dose. Since the hearing loss caused by impact or continuous noise is clearly different in the highest NIL ranges, safety criteria for impact noise should be revised. The NIL defined by Burns and Robinson underestimates the effect of the exposure time for impact noise.

ABSTRACT

From compulsory screening examinations of 260,917 noise-exposed workers standardized audiograms as well as medical and occupational histories of 110,647 workers were selected because of full-time exposure to well-defined noise greater than 85 dB (A) and analyzed by loglinear and multiple linear regression. The most important factors for prediction of pure-tone hearing loss at 4 kHz were found to be age, sex and noise immission level. For predicting speech impairment and handicap the history of ear disease, head injury and tinnitus were more important than noise immission level. Dose-response relationships are given to improve prevention and compensation of hearing loss from combined factors.

ABSTRACT

Weighted regression analysis was applied to determine the dependence of the hearing thresholds of 47,388 noise-exposed workers on age, sex, noise immission level, ear disease, head injury, tinnitus, hearing protector usage, and audiometric frequency in the range from 0.5 to 6 kHz. It could be shown that the hearing thresholds at any frequency are dominated by the age of the worker and that women, after equivalent exposure conditions, hear better than men. The relative effects of sex, noise immission level, ear diseases, tinnitus, and hearing protector usage are related to the audiometric frequency. Users of hearing protectors at the last audiometric investigation hear worse than nonusers. Hearing protector usage is strongly related with the hearing threshold in the low-frequency range. The noise immission level does not noticeably affect the hearing threshold below 3 kHz. The most important frequency of the noise immission level is as expected 4 kHz. For 4 kHz, it was shown that the variables age, noise immission level, tinnitus, head injuries, and ear diseases act in a good approximation additively on the pure-tone hearing threshold.

ABSTRACT

Out of data on 25,544 workers exposed to noise three groups of the same age and of equally high exposure are selected, which serve to study the effects of the varying periods of noise exposure. A regression-analysis is made for both men and women in each group. Due to the method of analysis chosen the ascent of the regression-line (regression-coefficient) represents exclusively the effects of noise-exposure on the loss of hearing. The regression-coefficients for men and women turn out to be the same. Thus, contrary to previous studies, there is no difference between men and women in the effects of occupational noise-exposure on the ability to hear. The fact that male workers exposed to noise suffer usually from a more deteriorated sense of hearing than female workers can be explained by the increased effects of presbyacusis.
