Methods: The participants (n=120) were recruited from flour mills at South Cairo. A questionnaire, clinical examination, chest x-ray,spirometry, bronchodilator test andpeak flow rate variabilitytest were done. Occupational asthma was diagnosed according to GINA guidelines. Results: This study showed that 25% of mills workers had asthma related to work.The asthma symptoms appearduring work which showed improvement after leaving workplace. It showed also reversibility in FEV1,PEFR as well as diurnal PEFR variability characteristics of occupational asthma. It revealed also that asthmatic workers had lower level of spirometric parameters in relation to non-asthmatic. Conclusion: Asthma questionnaire followed by ventilatory function test assessing reversibility and variability can be used for early diagnosis of occupational asthma in Egypt. | ||||
