Noise, as the most common physical agent in workplace, not only causes hearing loss but also leads to various diseases, such as hypertension and cardiovascular disease. Sound is likely to stimulate and increase the secretion of adrenal catecholamines, and may have an indirect role in the pathogenesis of diseases caused by stress. This study was performed to investigate the effect of noise on ur...

This study investigated the hypotheses that occupational exposure to acid mists is positively associated with periodontal disease, assessed by periodontal attachment loss. The study sample included 530 male workers at a metal processing factory. Data were obtained from interviews and oral examinations. Periodontal attachment loss was defined as >or= 4mm at probing, in at least one tooth. A job ...

In May 2000, an occupational medicine physician contacted the Missouri Department of Health and Senior Services (MoDHSS) to report eight cases of fixed obstructive lung disease in former workers of a microwave popcorn factory. Four of the patients were on lung transplant lists. All eight had a respiratory illness resembling bronchiolitis obliterans with symptoms of cough and dyspnea on exertion...

To clarify the relationship between erythrocyte Na+/K+-ATPase activity and haematological findings, several clinical laboratory examinations were performed on 31 male workers employed in a scrap lead refining factory and, as controls, 50 male workers employed in railway construction. The results were: (1) Values for erythrocyte Na+/K+-ATPase activity, blood and urine lead, urine delta-aminolaev...

The study was conducted on 27 rubber factory workers for the functional assessment of brainstem auditory pathway. Neurobehavioural questionnaire was administered to the workers and the personal sampler was used to evaluate the respirable particulate load inhaled per day of each worker along with qualitative analysis for PAH compounds. Evoked potential recording was carried out for brainstem aud...

Occupational skin disorders, in particular inflammations, dryness and erythema, in 80% of cases affect the skin of hands. The most frequent diagnosis, in over 90% of cases of occupational skin diseases, points to an irritant or allergic contact dermatitis. Our aim was to study the prevalence of self-reported skin symptoms on hands and forearms in different populations. The study was conducted o...

Background & Aims of the Study: Serum paraoxonase (PON1) is a potent antioxidant that is associated with the pathogenesis of several diseases. Also, it is reported that environmental factors can modulate the PON1 activity. In this study, the association between the Organophosphates (OP) exposure and plasma Paraoxonase/Arylesterase (PON1) activity and also OP-induced oxidative stress was investi...

Somatosensory evoked potentials (SEPs) on median nerve stimulation were studied in 38 rubber factory workers to detect possible subclinical impairments in the somatosensory pathway as a result of exposure to rubber factory chemicals. Results showed trend towards the prolongation of latencies of all the major peaks of SEP such as P1, N1, P2, N2, P3, N3 in exposed workers besides changes in peak ...

OBJECTIVE Lock and key factory workers are under the risk of metal pneumoconiosis and occupational asthma. In this cross-sectional study, it's aimed to evaluate the relationship between metal dust exposure and respiratory symptoms, pulmonary function tests of workers in different section of lock and key factory. METHODS 54 male workers (mean age, 32.8 ± 5.4) in a security and safety products ...

PURPOSE Shoe manufacturing workers are exposed daily to an extensive range of potential physical and chemical occupational hazards. Shoe manufacturing in Indonesia is one of the industrial sectors that has shown sustained growth amongst the newly industrialized countries (NICs). In this study, we investigated the possible potential exposure of the workers to physical and occupational hazards an...
