  ABSTRACT: An apparent excess of abnormal urine cytological findings in crime laboratory workers exposed to potentially carcinogenic aromatic amines was investigated by a cross-sectional epidemiologic study comparing these workers with an unexposed control group. The prevalence of atypical findings in the laboratory workers exceeded that in the control group; however, the results were not statistically significant. A number of serious problems were identified including a high prevalence of inflammatory changes (25% to 26%) and a moderately high percentage of atypical changes (2.5% to 5.4%) in the control population, failure to detect (on urological workup) evidence of neoplastic disease of the urinary tract in any of the laboratory workers whose urine examinations were cytologically interpreted as either atypical or neoplastic cells, and difficulty in determining proper referral criteria for urological workup.

  ABSTRACT: Results of over 800 medical surveillance ocular examinations on microwave and laser workers were evaluated using multiple regression analysis techniques. No lenticular or retinal defects were noted that could be attributed to work with either microwave or laser radiation. Increased incidences of minute lenticular defects were noted with increasing age. A high variability in the recording of such defects at different locations was attributed to differences in the subjective evaluation of individual examiners. It was concluded that periodic medical surveillance as conducted on the microwave and laser workers under study was nonproductive and suggestions were made to limit medical surveillance for these worker groups to preassignment, postaccident exposure, and termination eye examinations.

  ABSTRACT: This study examines the value of urine cytology as a medical surveillance technique in the industrial setting through an evaluation of the variability in interpretation of urine cytology slides. Urine samples were collected from 259 individuals for cytological examination. The slides were read by pathologists and screeners at one large Army medical center and separately read again by an independent pathologist at another Army medical center. The two independent readings for each of the 259 cases were compared. The comparison indicated that overall agreement was fairly high in reporting the presence or absence of inflammatory cells, red blood cells, and atypical (including metaplastic) cells. However, considering positive findings of the presence of red blood cells or atypical cells only, significant differences between the two independent readings were noted when the sign test was applied. Implications of these findings are discussed in light of the use of urine cytology as a medical surveillance tool in occupational medicine.
