Hairdressers have an increased risk of developing occupational skin diseases due to exposure to skin irritants and sensitizers. In the present work a method of assessing dermal exposure to permanent hair dyes was developed. The sampling performance characteristics of hand wash sampling with bag rinsing were studied for five hair dye compounds. The effect of residence time, sample load and different matrices were studied. Thirty volunteers were exposed to a reference solution of these compounds and to commercial hair dye products. The sampling efficiency after 5 min residence time was between 70 and 90% for the dye components in the hair dye products. Sampling efficiency decreases with increasing residence time, making the time of sampling an important factor. Hand wash sampling should be performed as soon as possible after the work task of interest. We conclude that the sampling efficiency is adequate for measurements of dermal exposure to permanent hair dyes. Hand wash sampling with bag rinsing is a useful tool for field studies of dermal exposure assessment in hairdressers.
The World Wide Web (WWW) offers physicians as well as their patients a huge resource of health information, which can be attained within minutes. Nevertheless it is difficult to select the needed information out of the mass of provided data and their quality is often poor with many unproven statements. Occupational dermatologists can especially benefit from the internet as they need a wide range of data from many sources. Much of this data can already be obtained via internet. To facilitate their search for information, this article presents a selection of German websites. The quality of the websites has been assessed using criteria such as design, search function, provided links and medical information. The results revealed deficiencies in the transparency of the data, e.g. often it is not apparent who is responsible for the information or when they were updated.
To compare the prevalence of natural rubber latex (NRL) sensitization and allergic contact urticaria from NRL in healthcare and non-healthcare workers, we studied all 1171 patients who attended our clinic during 2001 and 2002. Prick testing for NRL and patch testing with European standard series were performed in all patients and an additional rubber series in those who had contact with rubber. Specific immunoglobulin E (IgE) levels against NRL and tropical fruits were measured when prick testing was positive. Sensitization to NRL (positive prick test and specific IgE levels) was much more common in healthcare workers than that in non-healthcare workers, 16.7 versus 2.3%. Among the non-healthcare workers, sensitization to NRL was more common in food handlers (17.1%), construction workers (6.6%), painters (6.2%), hairdressers (5.1%) and cleaners (3.8%). The difference in the prevalence of specific IgE to tropical fruits was not significant. Allergic contact urticaria from NRL was also much more frequent in healthcare workers, 71.4 versus 28.6%. In conclusion, sensitization to NRL and allergic contact urticaria from NRL are more common in healthcare workers, but this is a growing problem in non-healthcare workers and should be investigated in all workers with a history of NRL intolerance or who have contact with NRL.
