This is the 18th Annual conference which concentrates on physical effects on cells, tissues and organisms (mechanical, electrical, magnetic, ultrasound....). The Queen Mary is both hotel and conference center. Abstracts are now being requested and the Deadline is June 1, 1998. Some highlighted topic areas this year are: --Mechanical, ultrasound, E-M effects on cytomorphology and wound healing. --Cell membrane sealing and fusion. --Mechanical and E-M effects on tissue morphogenesis. Please see and mark the following WEB site for Abstract information, Call for Papers, a picture of the Queen Mary, and other program details as they become available: WWW.ec.hscsyr.edu/sprbm All aboard! . ========================= Joseph A.

Liboff) Newsgroups: bionet.emf-bio Subject: Appliances and Leukemia Date: 18 May 1998 11:22:01 -0700 Organization: BIOSCI International Newsgroups for Molecular Biology Lines: 71 Sender: daemon@net.bio.net Approved: afrey@uu.net Distribution: world Message-ID: <199805181610.MAA12436@cliff.acs.oakland.edu> NNTP-Posting-Host: net.bio.net A peculiar report appears in the May 1998 issue of Epidemiology (Hatch, Linet et al, 9: 234-245). The possible correlation of exposure to household appliances and acute lymphoblastic leukemia (ALL) in children up to 14 was examined, both pre- and post-natally in nine states for 640 patients and 640 matched controls. THis report is peculiar for a number of reasons. First, although the (eleven) authors seem to have been motivated to undertake this study because of the magnetic fields associated with 60 Hz appliances, they dismissed whatever positive correlations that were obtained as probably having little to do with magnetic exposure: "...we think that a causal relation between magnetic fields from the appliances and [ALL] is unlikely...". The underlying reason for this conclusion is that such a finding might seem to contradict a prior study in 1997 by the same group (Linet et al, New England J. of Medicine, 337: 1-7) which claimed that it was not possible "to link measured magnetic fields in residences to leukemia...". At times, we are all a little guilty of looking at our own work as the last word, as the most definitive. But somehow I expect more of epidemiologists. Perhaps it's because they wear their objectivity on their sleeves. They hardly ever smile or frown for fear that someone will accuse them of expressing an opinion. However, judging from the way this group invoked its own prior research in coming to its conclusions, perhaps they are more human than I thought, as self-serving as the rest of us. A more thoughtful reading of their results might have treated their data set in an independent manner, without resorting to the results of a totally different study to color their conclusions, particularly in view of the very different protocols and objectives employed in the earlier work. On the other hand, there is something to be said for a group seeking the appearance of consistency in consecutive studies, especially when large sums of money and time are involved. Another strange thing about the conclusions from this report is that they are tied strongly to the premise that for magnetic fields to have any possible causal relationship to ALL, there must be evidence of a dose-response. Especially strange is that their prior report on power line fields seemed to take the opposite point of view, that whatever dose response was observed, it had little to do their findings. In any event,this premise has less to do with epidemiology and more to do with science. It has been pointed out, not only by me, but also by others, that magnetic intensity as an independent variable is merely one metric among many others. Investigators looking at the epidemiological aspects of magnetic fields should rethink the approach that deals with B-fields as if these will necessarily act in the same manner as a chemical carcinogen, with magnetic intensity playing a role similar to ppm contamination or daily milligrams consumed. There are only three dimensions that comprise the universe of chemical carcinogens, the formulation, the concentration, and the rate of exposure. By comparison, the potential number of dimensions for independent B-field interactions include, among other things, the intensity, the three spatial directions, the frequency, the various AC/DC combinations, the gradient, the waveshape, and carrier modulations. For each of these nine variables there are separate interaction possibilities. If one finds evidence for a leukemia correlation with magnetic field, it is not correct to discount this evidence simply because of an "inconsistency in the dose-response patterns". A.R.
