OBJECTIVE To determine the prevalence of hearing loss associated with occupational noise exposure and other risk factors. DESIGN A cross-sectional study involving 269 exposed and 99 non-exposed subjects (non-industrial noise exposed subjects) randomly selected. Current noise exposure was estimated using both sound level meter and noise-dosimeter. Past(More)
Stress urinary incontinence is a common problem among women of all ages but may resolve with pelvic floor reeducation in many cases. Compliance to a regimen of pelvic floor muscle exercises is poor and many devices have been produced to make exercising these muscles more effective and interesting. This article describes a study in which two such devices --(More)
The objective was to investigate the reliability and effects of age and noise on high-frequency hearing thresholds. A cross-sectional study was used involving 187 exposed and 52 non-industrial noise-exposed subjects selected randomly from noise-exposed and non-industrial noise-exposed subjects, respectively. Each subject was tested with both(More)
The efficacy of ultrasound examination by the trainee urologists in the management of urological emergencies admitted in a district general hospital was studied. Fifty patients (100 kidney units) had renal ultrasound performed by urological trainees on acute admission. The results were compared with subsequent definitive radiological investigations. On(More)
Inflammatory Bowel Disease (IBD) is partly caused by oxidative stress from free radicals and reduced antioxidant levels. Using hydrogen peroxide to induce oxidative stress in vitro in peripheral lymphocytes we investigated the induction of DNA damage supplemented with ethanolic extract of Chaga mushroom as a protective antioxidant. Lymphocytes were obtained(More)
A retrospective study was conducted in 75 consecutive patients requiring postmastectomy breast reconstruction over a period of 30 months. Each woman was offered one of the following four reconstructive options: free transverse rectus abdominis musculocutaneous flap (total number of reconstructions, n = 34); latissimus dorsi musculocutaneous flap (with or(More)
1. The effect of providing information about medicines by a short 'sales' interview between individual general practitioners and an 'academic representative' on prescribing was investigated. 2. The promotional campaign was designed to encourage a rational approach to prescribing of non-steroidal anti-inflammatory agents in an intervention group of 101(More)
underestimate the effect of an intervention on the burden of illness. Future research should collect serial data on severity to estimate changes in " total illness. " 2 Secondly, for trials of a new intervention the control is usually nothing (placebo). But for trials of antibiotics for acute respiratory infections the established treatment is already(More)
BACKGROUND A high prevalence of 50-65% iron-deficiency anaemia in mothers and infants in Jordan was reported by the United Nations Relief and Works Agency (UNRWA) in 1990. Iron-deficiency in infancy has been shown to delay cognitive and psychomotor development with long-term consequences. While socioeconomic deprivation and inadequate nutrition are known(More)
The psychometric function relating stimulus intensity to response probability generally presents itself as a monotonically increasing sigmoid profile. Two summary parameters of the function are particularly important as measures of perceptual performance: the threshold parameter, which defines the location of the function over the stimulus axis (abscissa),(More)
