CAN EXPOSURE TO NAIL SALON CHEMICALS/DUST INCREASE THE RISK OF DEVELOPING OCCUPATIONAL ASTHMA?
Quy Nguyen, Bill Pruitt; Univ of South Alabama, Mobile, AL
Background: Nail salon technicians (NST) are exposed to various inhaled agents (chemicals/dust) during work. This exposure may increase the risk of developing occupational asthma. Methods: A study group of 15 NST and an unmatched convenience group of 15 controls were recruited. A questionnaire was used to gather information from both groups on demographics, smoking history, respiratory symptoms, occupational exposure (and use of protective equipment for NST) as well as ventilation status in the nail salons. PFT and FENO measurements were done for all participants. Results: In the study group, three of the 15 participants had abnormal spirometry values; none of the 15 had high FENO values. For two study group participants, the FEV1 % predicted was 78 and 76 (< 80% is normal). One participant in the study group had a low FEV1% of 53 ( < 70% is normal). None of these participants had any respiratory symptoms or complaints (however, two study group participants with normal spirometry complained of a cough). FENO measured at less than 35 parts per billion (ppb) for all study group participants. (In steroid-naive persons, respiratory symptoms and FENO < 35 ppb has been suggested as compatible with a diagnosis of asthma). In the control group, 4 of the 15 participants had abnormal spirometry values and none had high FENO values. Three control group participants had low FEV1% predicted (79%, 68%, and 77%). One of the three also had a low FVC% predicted (71%). One control group participant had a low FVC% predicted (78%). None of these participants had any respiratory symptoms or complaints (however, one control group participant with normal spirometry complained of a cough). Discussion: Exposure to work place chemicals/dust can cause chronic or acute respiratory conditions. In the current study, results are inconclusive although participants in control group seem to have slightly more related respiratory symptoms than study group. Conclusions: This study data does not appear to support a conclusion that exposure to nail chemicals causes any occupational related respiratory disease.
