Another autism report

Reader Josh sent a link to the Immunization Safety Review Committee's 2004 Immunization Safety Review: Vaccines and Autism whose description reads in part:

This eighth and final report of the Immunization Safety Review Committee examines the hypothesis that vaccines, specifically the measles-mumps-rubella (MMR) vaccine and thimerosal-containing vaccines, are causally associated with autism. The committee reviewed the extant published and unpublished epidemiological studies regarding causality and studies of potential biologic mechanisms by which these immunizations might cause autism. Immunization Safety Review: Vaccines and Autism finds that the body of epidemiological evidence favors rejection of a causal relationship between thimerosal-containing vaccines and autism. The book further finds that potential biological mechanisms for vaccine-induced autism that have been generated to date are only theoretical.

The 214 page report is available for download as a .pdf for ~$35. And to be fair, I haven't been following this issue closely, so I don't know what's "right." I'm just interested in the issue, especially these days as more and more of my friends are starting families.

Searching for autism’s causes

There seems to be a lot of discussion lately about what causes autism (see, for example, this recent column by Robert F. Kennedy Jr., Vaccines and Autism: Looking for the Truth? Study the Amish). Most of what I've read focuses on preservatives in childhood vaccinations as the cause. But an interesting op-ed in yesterday's New York Times, The Male Condition, by Simon Baron-Cohen (the director of the autism research center at Cambridge University) hypothesizes that genetics, rather than environmental factors, may be the cause of autism:

One needs to be extremely careful in advancing a cause for autism, because this field is rife with theories that have collapsed under empirical scrutiny. Nonetheless, my hypothesis is that autism is the genetic result of "assortative mating" between parents who are both strong systemizers. Assortative mating is the term we use when like is attracted to like, and there are four significant reasons to believe it is happening here.

The reasons he outlines sound pretty compelling to me, and I look forward to seeing further research that could support his assertions.

The joy of the outdoor shower

Outdoor ShowerA common feature at beach houses in New England is the outdoor shower. (It may be common at other beach houses in other places too, but I don't have experience with that.) It's supposed to keep people from getting the inside of the house all sandy after a day at the beach, make it easy for a quick rinse off of salt, etc., and probably also handle the extra bathing requirements of a house full of guests. But beach day or not, hot day or cool, I use the outdoor shower whenever I possibly can! Because there's something so pleasant about taking a shower outside — watching the trees bend in the wind and the clouds move across the sky and listening to the birds twitter and squeak. Unlike the indoor shower, which is dark and cramped, outdoors the feeling is expansive, almost wild. I feel it lends itself to the best shower thinking and day dreaming. It's just such a nice start or end to the day. The true end of summer for me is marked by the day when I have to return to the indoor shower.
