Separate diagnostic dust mite lists for the coastal and inland areas because of climatic and dwelling differences required to be implemented. Compared with traditional heating, central heating significantly increases the risk of exposure to Der f 1 levels >2 microg/g of dust (odds ratio, 7.35; 95% confidence interval, 1.43-37.87; P = 0.01).

The authors aimed to examine potential relationships between work-related symptoms attributed to sick building syndrome (SBS) and certain psychological, somatic, and environmental factors. The multidisciplinary, cross-sectional study comprised 171 female subjects working in air-conditioned and naturally ventilated nonindustrial office buildings. The authors collected information concerning symptoms related to SBS and made assessments of quality of life by using appropriate questionnaires. They assessed the women's levels of emotional stability or neuroticism using the Cornell Index. They determined skin and airway reactivity markers and indoor microclimate data by using standardized methods. The study showed that the subjects had a high prevalence of fatigue (60.2%), sore and dry eyes (57.9%), and headache (44.4%), as well as a generally high score according to the SBS Index. Neuroticism and subjectively estimated physical health as well as the type of building ventilation significantly contributed to the prediction of the SBS Index, explaining 15% of the variance.

Present study aimed at an integral assessment of sister chromatid exchange (SCE) frequencies in the health care workers occupationally exposed to cytostatics. The results of 500 individual analyses were evaluated. Drug handling practice was investigated in parallel and the results showed that cytostatics are mostly prepared outside hospital pharmacy (98%) and mainly handled by nurses (96%). Mean frequency of SCE was 5.63 +/- 2.28, while HFC represented 9.65% of the cells analysed. Both values were higher compared to previously established control values for Croatian population. The duration of exposure, profession, age, gender, smoking habit, medical exposures, and simultaneous exposure to other occupational mutagens significantly contributed to SCE and HFC values. The usefulness both biomarkers in the assessment of cytogenetic damage is confirmed. Since current practice in Croatian hospitals does not include regular monitoring of workplaces, to ensure maximal occupational safety, a surveillance on exposed health care workers, including periodic biomonitoring, is recommended.

The effect of handling antineoplastic drugs was examined in 42 nurses working in an oncology department, and the same number of nurses not exposed to antineoplastic drugs acted as controls. The exposure effect was evaluated by analysis of sister chromatid exchanges (SCE) incidence and structural chromosomal abnormalities. SCE as well as chromosomal abnormalities in the exposed group were increased (p less than 0.001 and p less than 0.01, respectively). Sign test for paired sample was used for statistical assessment.
