OBJECTIVES: To determine the prevalence and related factors of work related musculoskeletal symptoms in hairdressers. METHODS: Informations on general characteristics, job strain, and musculoskeletal symptoms were obtained by a self-administered questionnaire, through adopting NIOSH instrument and JCQ(Job content questionnaire), from 267 hairdressers, between March and May, 2000. RESULTS: The symptom prevalence by NIOSH surveillance criteria in total was high as 94.4%; shoulder (61.0%), neck (59.9%), low back (53.2%), hand and wrist (41.6%), etc. In multiple logistic regression, significant factors affecting the symptoms by body region; job insecurity on neck' gender, alcohol, decision latitude on low back; alcohol on hand and wrist; smoking on thigh and knee,' smoking, decision latitude on ankle and foot; job insecurity on upper back. CONCLUSIONS: Musculoskeletal symptoms of hairdresser were highly prevalent, and associated with job strain and their health habits. This is a basic data of work related musculoskeletal disorders among hairdressers who are not the subjects of occupational health service at the present time in Korea.

OBJECTIVES: Lung injuries due to exposure to nitrogen oxides can occur in various process in industry. We experienced a case of chemical pneumonitis induced by accidental inhalation of nitrogen oxides emitted from the bath in an acid dipping operation. CASE: Dyspnea, cough and blood-tinged sputum production, cyanosis, and tachypnea occurred after exposure to oxides of nitrogen. There were bilateral diffuse ground glass opacities in simple chest radiography and high resolutional computed tomography, hypoxemia in arterial blood gas analysis, mixed ventilation defect and reduced diffusion capacity in spirometry. As an oxygen and supportive therapy, after hospitalization, was given, the patient recovered completely from the lung injury on the 8th day after admission. There was no evidence of delayed onset of bronchiolitis obliterance or pulmonary edema in a follow-up for about 6 months. CONCLUSIONS: Acid dip operation require more efficient hooding and exhausting system for the prevention of lung injuries caused by inhalation of nitrogen oxides. Also health education for worker need.
