  • Proper Interpretation of DDREF in IREP
    John R. Trabalka

    The comment by the authors about the computer code IREP used by NIOSH, namely: “IREP includes a DDREF, which lowers the probability of causation [PC] for low-dose-rate exposures,” has the potential to be misinterpreted. IREP contains two discrete DDREF distributions, one for most solid cancers and another, more restricted, distribution for thyroid and female breast cancers. The first mentioned, with values of DDREF rang...

  • Biological monitoring of wood dust exposure
    Heikki Savolainen

    Dear Editor,

    This informative article on the occupational wood dust exposure in Italy requests a monitoring method for received personal doses. Such a method exists exploiting samples obtained by nasal lavage (1). It is based on the the chemical analysis for wood polyphenols. Although they are species specific they are good quantitative indicators of hardwood dust particles coarse enough to be retained in the na...

  • Respiratory disease by diisocyanate exposure
    Heikki Savolainen

    Dear Editor,

    As described in this investigation only a minority workers with an occupational asthma due to a diisocyanate exposure have specific IgE antibodies towards the monomers (1).

    Therefore, it is likely the host factors play an important role (2). However, their significance may not be so firm so as to be used as predictors of a disease. The concept is, however, important in the workers´ compen...

  • Response to Chris J Kalman
    Adeleh Shirangi

    June 8th 2009

    We are writing to respond to Dr.Kalman in regard to our article entitled “Maternal Occupational Exposure and Risk of Spontaneous Abortion in Veterinary Practice”.

    Regarding the risk relating to radiation, we presented data separately for those with 1-4 x-rays a week in Table 2. Readers are able to use these analyses rather than those in Table 3 if they prefer. The results for exposure...

  • Response to authors
    Chris J Kalman

    Dear Sir

    I am grateful for the speedy response from Dr Shirangi and her colleagues to my original letter. I regret the delay in my further response.

    Importantly, the authors justify the combination of the ‘no exposure’ and ‘one to 5 films per week’ categories (ie the elimination of an exposure category) on the identification that the crude relative risk data did not indicate any adverse outcome for t...
