Exfoliative Cytology of the Upper Respiratory and Urinary Tract among Sudanese Fuel Station Workers

Abstract

tlbjective: The aim of this study is to evaluate the cytological changes in the cells of the respiratory and urinary tract among Sudanese fuel station workers. Design: This is a retrospective cohort case control study carried out in Khartoum state. lflaterial and methods: The study sample consists of zooparticipants selected from the relevant population. Most of the study's participants were Arab and Africans. A sample of 100 was collected from different fuel stations workers (cases), and another 100 samples were also selected from non-fuel stations workers (control). From each group, two samples of sputum and urine were collected, and then the samples were processed, stained and microscopically examined. Results: The acute inflammatory cells were seen in sputum smears in 28 of the cases and 18 of the controls, and the chronic inflammatory cells were seen in 9 of both cases and the controls. ln the urine specimens the acute inflammatory cells were seen in 19 of the cases and 5 of the control and the chronic inflammatory cells were seen in 2 of the cases and none of the controls show chronic inflammation. This indicates that exposure to benzene is a major factor that contributes to inducing inflammation in the urinary bladder, but not the in lungs.The 4 '1' Annual Conference ¢-L'-ll @515-ll L25-ll ¢'\-U-‘ii J43-e Ministry Of Higher Education (4,-ll-ll ¢->.-"J Q-“#31 9:5-3| bbu) &Scientitic Research (GCNU‘t) pY- ‘V/\ Y/\ ~-‘t Exfoliative Cytology of the Upper Respiratory and Urinary Tract among Sudanese Fuel Station Workers lltabab.
