“…However, the magnitude of chronic airway disease after long-term exposure to cotton dust remains unclear. Several studies have indicated that longterm exposure may lead to chronic respiratory disease [1][2][3] and excessive loss of lung function [4,5], whereas others have not [6,7]. Due to a scarcity of longitudinally collected data, some important questions remain unresolved.…”

In order to evaluate chronic effects of long-term exposure to cotton dust on respiratory health, and the role of dust and endotoxin, longitudinal changes in lung function and respiratory symptoms were observed prospectively from 1981 to 2001 in 447 cotton textile workers, along with 472 silk textile controls.The results from five surveys conducted over the 20-yr period are reported, including standardised questionnaires, pre-and post-shift spirometric measurements, work-area inhalable dust sample collections and airborne Gram-bacterial endotoxin analysis.Cotton workers had more persistent respiratory symptoms and greater annual declines in forced expiratory volume in one second (FEV1) and forced vital capacity as compared with silk workers. After exposure cessation, in the final 5-yr period, the rate of FEV1 decline tended to slow in nonsmoking males, but not in nonsmoking females. Workers who reported byssinotic symptoms more persistently suffered greater declines in FEV1. Chronic loss in lung function was more strongly associated with exposure to endotoxin than to dust.In conclusion, the current study suggests that long-term exposure to cotton dust, in which airborne endotoxin appears to play an important role, results in substantial adverse chronic respiratory effects.

“…42 It may be due to inhalation of chemical agents resulting from cotton dust and textile dyeing. 43 In the current study, we did not found any association between accompaniments of children to their parents in textile industry. But working mother or father in the textile industry was associated with risk of AE.…”

A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : To evaluate trends in the prevalence of symptoms and risk factors of atopic eczema in 13-14 years old school children in Denizli. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : This survey was first conducted in 2002 and repeated in 2008 using the same ISAAC questionnaire in the same age group. Possible risk factors were also asked. R Re es su ul lt ts s: : A total of 3004 children (response rate, 93.8%) in 2002 and 4078 children (response rate, 75%) in 2008 were included into the studies. Doctor diagnosed eczema ever increased from 2.1% to 3% (POR =0.7, 95% CI = 0.52-0.95, p= 0.015). The prevalence of itch rash ever and itch rash in last 12 month decreased respectively from 20.8% to 14.7% (POR =1.52, 95% CI =1.39-1.72, p<0.001) and from 15.4% to 9.5% (POR=1.72, 95% CI=1.49-1.99, p<0.001). The prevalence of itch rash with typical distribution, itch rash cleared completely in last 12 month and kept awake at night by this itchy rash in last 12 month were significantly decreased in 2008. Atopic family history, tumble drying at home, working father or mother in textile industry were found as significant risk factors for atopic eczema in 2008. C Co on nc cl lu us si io on n: : Although the prevalence of doctor diagnosed atopic eczema in 13-14 years age group was found to be increasing in Denizli, this study showed a decrease in the prevalence of typical clinical symptoms and signs of atopic eczema. Atopic family history, tumble drying at home, a working parent in textile industry were important risk factors for doctor diagnosed atopic eczema in 2008. Hayat boyu doktor tanılı egzema %2,1'den %3'e çıkmıştır (POR=0,7, %95 GA= 0,52-0,95 ve p=0,015). Hayat boyu kaşıntılı döküntü ve son 12 aydaki kaşıntılı döküntü sırasıyla %20,8'den %14,7'ye (POR=1,52, %95 GA=1,39-1,72 ve p<0,001) ve %15,4'ten %9,5'e (POR=1,52, %95 GA=1,39-1,72 ve p<0,001) düşmüştür. Tipik dağılımlı kaşıntılı döküntü, son 12 ayda tamamen düzelen kaşıntılı döküntü ve son 12 ayda bu kaşıntılı döküntü nedeniyle uykudan uyanma prevalansı, 2008'de anlamlı olarak azalmıştır. Atopik aile öyküsü, evin içinde çamaşır kurutulması, anne ya da babanın tekstil endüstrisinde çalışması 2008'de atopik egzema için anlamlı risk faktörleri olarak saptanmıştır. S So on nu uç ç: : Bu çalışma; doktor tanılı atopik egzemanın, Denizli'deki 13-14 yaş grubunda artmış olduğunu göstermesine rağmen, atopik egzema bulgularının ve tipik klinik semptomlarınn prevalansında azalma olduğunu göstermiştir. Atopik aile hikayesi, evde çamaşır kurutulması, ebeveynin tekstil endüstrisinde çalışması, 2008'de doktor tanılı atopik egzema için önemli risk faktörleri olarak bulunmuştur.A An na ah h t ta ar r K Ke e l li i m me e l le er r: : Dermatit, atopik; prevalans; risk faktörleri; eğilimler T Tu ur rk ki iy ye e K Kl li in ni ik kl le er ri i J J D De er rm ma at to ol l 2 20 01 16 6; ;2 26 6( (1 1) ): :1 1--9 9

CHRISTIANI DC, EISEN EA, WEGMAN DH, YE T-T, GONG Z-C, LU r-t., DAI H-L. Respiratory diseasein cotton textileworkers in the People's Republicof China: II Pulmonary function results. Scand J Work Environ Health 12 (1986) 46-50. Pulmonary function tests were performed pre and post workshift on 887 textile workers with at least two years of employment in two cotton mills and one silk mill in Shanghai, the People's Republic of China. Environmental sampling was performed with vertical elutriators, and pulmonary function was performed with standardized techniques. Cotton textileworkers were found to have greater across-shift decrements in forced expiratory volume in I s (FEVl.o) than silk workers. Increasing duration of exposure resulted in increasing acute decrements in FEVl. o, although significant acute decrements werefound in workers with lessthan fiveyearsof exposure. The acute changes in FEVl.o were noted in both symptomatic and asymptomatic cotton workers, though the difference between the across-shift change in FEVl.o (.6. FEVl. o 010) of the byssinotics and nonbyssinotics increased as work duration increased. There was no difference in preshift FEV 1 . o between the cotton and silk workers, but several selection factors likely influenced the observations.
