AIMS To characterise the development of noise induced damage to hearing. METHODS Hearing and noise exposure were prospectively monitored among a cohort of newly enrolled construction industry apprentices and a comparison group of graduate students, using standard pure tone audiometry and distortion product otoacoustic emissions (DPOAEs). A total of 328(More)
AIMS To validate the accuracy of construction worker recall of task and environment based information; and to evaluate the effect of task recall on estimates of noise exposure. METHODS A cohort of 25 construction workers recorded tasks daily and had dosimetry measurements weekly for six weeks. Worker recall of tasks reported on the daily activity cards(More)
AIM To examine the relations between noise exposure and other risk factors with hearing function as measured by audiometric thresholds and distortion product otoacoustic emissions. METHODS A total of 456 subjects were studied (393 apprentices in construction trades and 63 graduate students). Hearing and peripheral auditory function were quantified using(More)
In this paper we report the results of a longitudinal study which examined memory for a single routine activity of daily living in people with dementia of the Alzheimer type. We assessed memory in a natural setting, visiting volunteers in their homes. We video-taped performance on the selected task and analysed the record for the presence or absence of each(More)
This study was conducted to verify the performance of a recently developed subjective rating (SR) exposure assessment technique and to compare estimates made using this and two other techniques (trade mean, or TM, and task-based, or TB, approaches) to measured exposures. Subjects (n = 68) each completed three full-shift noise measurements over 4 months.(More)
Long-term sickness absence and incapacity benefits (disability pension) rates have increased across industrialised countries. Effective measures are needed to support return to work. The recommendations of this guidance were informed by the most appropriate available evidence of effectiveness and cost-effectiveness. Public health evidence was provided by(More)
OBJECTIVES Random errors in exposure data were explored to determine their effect on exposure-response relationships using individual, grouped, or combined (grouped and individual) exposure assessment methods. METHODS Monte Carlo simulations were conducted by generating small "studies" of one hundred subjects divided into four exposure groups. Observed(More)
BACKGROUND Treatment of childhood cancer occurs over a 2- to 3-year period, with initial intense phases of chemotherapy followed by less severe treatment periods. From first diagnosis, families are encouraged by healthcare professionals (following government guidelines) to try to maintain a normal life. The aim of this paper is to contribute to our(More)
We describe the Quality of Life (QoL) and IQ of survivors of retinoblastoma (Rb), both in relation to the normal population and between subgroups of Rb patients differing in relative risk (i.e. unilateral vs. bilateral disease). The sample included 54 children (28 males, age-range 8-16 years) and their mothers. Mothers completed standardized questionnaires(More)
