Lasers shooting into irises

I did not think my first minor surgery would involve someone shooting lasers to make holes in my iris. It sounds like more fun than it actually was, but was mostly painless and here I am, looking at a computer screen 3 hours later. My eyes feel like they’ve had about 5 hours of sleep, which is good considering they’re now sporting two brand new drain holes.

Laser iridotomy is also performed prophylactically(preventively) on asymptomatic individuals with narrow angles and those with pigment dispersion. Individuals with a narrow angle are at higher risk of an acute angle closure, especially upon dilation of the eye

I also just started reading Bad Science by Ben Goldacre, which is about the use and misuse of the banner of science by a large group of people including nutritionists, pharmaceutical companies and “alternative” treatment specialists. It has a great chapter on the “placebo” effect, how much of it is culturally mediated, and how much doctor demeanour and confidence in their skills and outcome affects results. The doctor shooting holes in my eye was extremely confident in their skills and their results, and normally, my brain would be sending off all kinds of hubris warnings. In this case, their confidence reassured me a bit, and Bad Science definitely helped. It was also interesting to see a large section on homeopathy in the book, since I’ve written about my contact with homeopathy and felt that the cultural practices of a good homeopath can be of some use to people as long as they don’t go too far. The book confirmed some of that.

    Bisphenol A – Getting More Powerful Everyday

    So is it Mondays with Bisphenol?? You know what, the scary thing about this chemical is that its acute (short term, immediate) toxicity at high doses, which is the only safety testing that is ever done, does not correlate with all the subtle effects that are seen at low doses (chronic). Here’s another study where ambient level exposure to bisphenol A interferes with prostate cancer treatment by making the tumor cells androgen independent, so the standard testosterone deprivation therapy will not work any more.

    Environmental Health News: New Science

    A common plastic molecule to which virtually all Americans are exposed may interfere with the standard medical treatment for prostate cancer, according to new experiments with human prostate tumors implanted into mice. The doses of the plastic molecule, bisphenol A, were chosen specifically to be within the range of common human exposures. Tumor size and PSA levels were significantly greater in exposed animals just one month after treatment.

    One of the principal known sources of exposure to bisphenol A in the U.S. is through its use to make a resin that lines the majority of food cans sold in markets. These new results by Wetherill et al. suggest men concerned about prostate cancer may want to reduce their consumption of canned goods and their use of polycarbonate water bottles, another common source of exposure

    This is one powerful (if not actually more dangerous) chemical. it is so ubiquitous that finding a substitute is not going to be easy.

  • www.oliveridley.org

    Every self important blog needs its own domain. I got http://www.oliveridley.org quite a while back. But I am finally setting up this blog to redirect to the eponymous url. The blog is still hosted on wordpress’ servers and nothing should change as far as the links, the rss, etc. Everything should forward seamlessly without delay to the new url. But, if there are issues with the rss feeds, the suggested fix is to re-subscribe using the new url.

    Now, to cure those summer blahs!

  • Rain in Chennai

    rainHard to believe, but it is raining in Chennai in the middle of  March.  Most people  I speak to  say that the last 3 years have seen extremely weird weather with rain patterns being completely unpredictable, rain in “spring”, cool weather this late in March, I guess the Chennaiwasis will take it, though the roads get completely messed up even with a few mm of rain. The streets are a lot cleaner, though the suburbs are still a nightmarish mess at times.

    Blogging has been non existent because I’ve been doing other things and I’ve been living without an internet connection, except for a half hour here and there everyday. So, no time or inclination, which is a pity, because Chennai is in such a state of flux that things happen everyday, there are pollution issues, transportation issues, zoning (or lack thereof!) issues, corruption, a dizzying pace of new construction, etc. Infrastructure can’t possibly keep up, but the authorities have done a good, if not great job in trying. Chennai has done a much better job than Bangalore, where traffic just does not move. Every month, there are new traffic patterns to try out, new one way streets, new flyovers and intersections, seriously, for someone who used these streets every day for many years, I find myself getting lost because I just can’t drive by landmark any more.

    Oh well, there’s still some greenery and beauty to be had, I went birding in Nanmangalam, in the Southern “suburbs” (no white picket fences in these suburbs!) and had the most wonderful time catching up with some old bird friends, the bulbuls, mynahs, bee eaters, cuckoos of various kinds, pheasants, raptors. kingfishers, babblers, warblers, snipes, many more, and my very favorite, the Great Horned Owl!! (the link is to an article detailing captive breeding of the owl in the forest I was in yesterday).

    Owl

    If you peek really hard, you will see the owl in the center of your picture, courtesy my 3X point and shoot (look up from the patch of white bird droppings, that is how we found the bird!). It’s a great site for birding, low scrub forest, and the birds pretty much show themselves, not very hard!

    So long, back in the US next week, thank heavens for always on wireless!

    Smoking bans in North Carolina?

    After this morning’s post about Tennessee, I got curious and wanted to see what we were doing in North Carolina on smoking bans. So, I looked up my very own NC General assembly homepage and used their full text bill search function (key word smoking!). Here’s what I found.

    In the State Senate

    Great! Senate Bill S635 will ban smoking in all public places indoors except in tobacco shops, designated smoking rooms in hotels and for “research”. Follow the progress of this bill using the bill’s very own rss feed!

    In the House

    Not so good, House bill H259 has been referred to committee. But it has giant loopholes for all bars and “private clubs”. It has its very own rss feed too.

    Observations

    1. It is good to see that my representatives Kinnaird (we share a yoga class on Monday nights!) and Insko are co-sponsors on the bills. But I live in that bastion of progressivism (in the South, anyways!) Chapel Hill/Carrboro, so this is pretty unsurprising!
    2. My question to the House is this: Why are bartenders, employees of bars and private clubs, and patrons of such establishments considered not worthy of protection from second hand smoke? As someone who goes out drinking often, this is where all my exposure to second hand smoke occurs.
    3. Kudos to North Carolina for designing an accessible and easily searchable bill repository complete with rss feeds, way to go!

    Once I hear back from Sen. Kinnaird on the prospects of legislation this session, I’ll be sure to post about it.

    Update: See this. The House and Senate bills have gotten a lot closer, and most of the loopholes are gone.

  • Religion

    A friend’s post on facebook triggered some thoughts on religion, so I expanded my comment (not science/policy related, so feel free to glaze over).

    I grew up Hindu, or shall we say, Tamil Brahmin. In India, each community’s practice of Hinduism is very different, informed by place, caste, class and more, so calling yourself a Hindu is not very illuminating. I went to the temples with my parents, and felt a connection with something (in hindsight, it was the architecture, grandeur more than Ganapathy) I prayed (after a fashion), more for specific things like “Oh god, let me do well in this test” rather than anything. I participated in the ritual and festivals, like any good kid. All this ritualistic practice aside, my single greatest spiritual memory as a young adult (and to this day) is a 5 minute meditation experience I had with my uncle sitting in a simple Ramakrishna Mission hall. I remember losing connection with my usually racing brain and reaching what I perceived as a meaningful connection with God, but what I would now associate with a particularly successful mindfulness practice. I still haven’t quite achieved that sense of “levitation” since.

    I remember being about 15, going to a really crowded temple (I think it was this one) and jostling with thousands of other people to get a fleeting glimpse of a stone (or gold plated? super rich temple!) idol, I lost my faith in one moment (at least, that’s how I perceive it). I persisted in going to temples and participating in ritual for a bit, hell, even going back to the same temple a couple of years later, but there was nothing there.

    ganapathyInto my late teens and twenties, I tuned much more into the powers of organized religion to oppress, deny freedom and restrict behaviour. At that age, I perceived the community around me using religion (in hindsight, it’s much more complicated) to restrict my activities and censure them (oh privileged male!). I was very likely to lump the people with their religion. I did not believe religion to be a force of anything other than restriction and censure, and I judged the people around me who still practiced their religion in spite of “ought to know better”. I very plainly refused to practice any rituals, or go to temples. Leaving India helped as well, since I had no community pressure to practice anything.

    Those years were ritual free (after a fashion), and I would call myself a primarily analytical person, using logic to solve problems (oh, so simple!). But, I did find ritual missing in my life. Into my thirties, I sub-consciously (at first) started to incorporate some ritualistic practices like morning coffee, regular gym workouts, and many other time based ritual activities as a substitute. My health and well-being definitely improved, though you could say the fact that I chose gym workouts as a ritual rather than bar hopping did not hurt! But, that’s really the point of ritual, isn’t it, to find the ones that centre you?

    As I grow older, I am less militantly anti-religious and more likely to incorporate yoga, mindfulness, meditation and other behaviours that could be associated with spirituality into my life. But I see them as healthy behaviours, almost like exercise rather than connecting me to something greater. I went through a phase wishing I could believe in a god again, it would be a lot easier than having to figure it out for yourself, but that passed. I am still as atheist as I’ve ever been, just a lot more tolerant of other people’s paths and processes. I understand that everyone’s well being depends on connection, whether it is social, or spiritual or physical. If their practice of “religion” or their belief helps them achieve that connection, that’s just lovely (The last few times I’ve visited India, I’ve even let my parents drag me on temple excursions!) That is, as long as they do not end up supporting oppressive homophobic, racist or misogynist behaviour based on religion. I still believe that most organized religion is a tool of patriarchy and control, and cynically uses people’s need for connection to achieve political power and money, so no support there.

    Meanwhile, in the other India

    While India prepares to spend many billions of dollars on fighter jets, it cannot provide clean water for its citizens.

    Cholera-diarrhoea toll mounts to 164 in Orissa-India-The Times of India

    Cholera and diarrhoea, having assumed epidemic proportions in three tribal dominated Orissa districts, have so far claimed 164 lives as officials confirmed five more deaths in worst-hit Koraput on Thursday.

    The death toll, which had mounted to 159 on Wednesday, further rose to 164 with confirmation of five casualties in Dasmantpur block of Koraput district, Chief District Medical Officer (CDMO) R K Agarwal said.

    While the toll in Koraput district went up to 73, the situation remained by and large unchanged in Rayagada with 64 casualties as the killer diseases claimed as many as 27 lives in Kalahandi, official sources said.

    The water-borne diseases had assumed epidemic form in nine blocks of these three backward districts located adjacent to each other though separated by hills and the waterspread of the vast Indravati reservoir.

    Despite state government’s claim to have effectively controlled the spread of the diseases, residents of the affected areas alleged that the administration had failed to provide adequate medical facilities to the patients.

    This is disgusting and very symptomatic of the urban-rural divide that exists in India. Unless the government can provide basic infrastructure to its rural citizens, all those fancy malls and F16s mean little.
