of new study on melanoma of the eye
A recent article
outlined the design of a study of uveal melanoma (a tumour of the
iris and related structures in the eye). Exposure to radiofrequency
radiation from cell phones is one of the main areas to be explored,
but a variety of potential risk factors will be included. The study
compares newly diagnosed cases of the tumour in Germany with controls.
The latter are of three types. Population-based controls are randomly
selected from population lists, and will be matched to the cases
for age, gender, and residential area. A second group will be drawn
from the clients of ophthalmologists who have referred cases to
the study. A third group will be siblings of cases. Data will be
collected by self-administered questionnaire and by telephone interview.
The authors hope to publish the study results in the summer of 2005.
for the research study was the publication of another German study
on uveal melanoma in 2001 (Stang and colleagues). Three of the authors
of the present paper contributed to the earlier paper. The 2001
study was criticized on methodological grounds. For more, see "What's

of health effects of RF exposure
of the epidemiology of health effects of exposure to radiofrequency
radiation has been published. The conclusions of the authors are
similar to other reviews:
"Results of epidemiologic studies to date give no consistent
or convincing evidence of a causal relation between RF exposure
and any adverse health effect. On the other hand, these studies
have too many deficiencies to rule out an association".

studies of self-reported cell phone use
A group of German
researchers has published two papers describing studies in which
they assessed the validity of self-reported cell phone use, as documented
in a questionnaire used in the INTERPHONE study (see "Research
Programs - IARC).
The authors found good correlation between self-reported use and
information provided by network providers in terms of the number
of calls per day. The correlation was moderate with regard to cumulative
