“…The difference of abnormal pulmonary function between smokers and nonsmokers increased with increasing duration of exposure. The percentage of workers with asthma, occurring after the age of 30 and after entering the company, was found importantly high among the group with spirometric declines, while the prevalence of allergic rhinitis was particularly frequent disease (Chaari et al, 2009;Huggins et al, 2005;Sauni et al, 2009). Table 3 showed the proportion of impaired lung function and the prevalence of respiratory symptoms, asthma and allergic rhinitis in the study population, N (N ¼ 443 workers), classified according to their smoking habits.…”

A number of epidemiological studies have shown that byssinosis is associated with exposure to high levels of cotton dust. In this first survey, the prevalence of respiratory symptoms in cotton workers under low concentration of cotton dust was investigated. A respiratory questionnaire consisting of 47 questions was given to 443 cotton workers. Their lung function was measured with spirometry. Breathing zone cotton dust concentration was measured by personal samplers and static sampling was used to define the level of the work area concentration. Workers with abnormalities in the pulmonary function parameters, including forced expiratory volume in 1 second (FEV₁), forced vital capacity (FVC) and peak expiratory flow rate (PEFR), were 5.9%. In this group of operatives 7.7% had symptoms compatible with byssinosis, 65.4% of them were smokers, 69.2% of them had symptoms of allergic rhinitis, while 72.2% of them were smokers. Asthma, which appeared after the age of 30, was reported by 57.7%, while 60% of them were smokers. Mean breathing zone cotton dust concentration was 0.16 mg/m³ and the mean work area cotton dust concentration 0.14 mg/m³. Despite the reduction in cotton dust concentration, byssinosis symptoms, allergic rhinitis, asthma and impaired pulmonary function are the most common findings in our cotton workers depending on the duration of exposure, whether they are smokers or not and the nature of the cotton dust.

“…With appropriate training and explanation, it is possible to achieve high quality recordings in workers suspected of asthma 39. While they are subject to potential falsification and inaccurate transcription, they offer the best and easiest first-line approach to assessing the physiological response to inhaled agents in the workplace.…”

“…A study was determined that 56% of the patient's made sufficient PEF measurements while made themselves, and this rate increased to 85% in the measurements made by the patients at the hospital [31]. Nevertheless, as in the COVID-19 pandemic, it is difficult to use PEF device while using compulsory respiratory protective equipment, and perform PEF in the workplace, and also part-time workers have difficulty to performing and analyzing their records [32].…”

Objective: It is recommended to monitoring PEFR to diagnosing OA. Gold standard method is SIC test. The aim of this study is to evaluate comparison of SIC test results in patients with OA and non-OA and to discuss PEFR monitoring and underdiagnosed.Materials and Methods: 24 patients (16 OA, 8 non-OA) who underwent SIC test were analyzed retrospectively. Results:Although number of patients exposed to LMW (wood powders [n: 5]) was higher, IgE level was found significantly higher at OA (697.39 ± 839.36 kU/ml) (p: 0.027). Average PEFR monitoring days mean was 26.53±12.90.13 patients who diagnosed with OA with SIC was evaluated PEFR monitoring results were negative [%92.86]. Minimum FEV1 value on exposure day was lower in OA (p:0.001). Conclusion:We detected underdiagnosed cases rates were higher with diagnosing OA with PEFR monitoring alone. Our study also demonstrated that LMW agents cause immunological OA, independently from agent type and duration of exposure.

Improving the quality of peak flow measurements for the diagnosis of occupational asthma

Abstract: The return rate of PEFs for diagnosing occupational asthma is better when patients have been given specific instructions from a PEF specialist and the data quantity better when recorded on a dedicated form.
