particularly related.<br>
<br>
The juxtaposition of these two events creates an interesting
perspective. &nbsp;While it is good news that Zarqawi is out of
action, it is bad news that the stock markets around the world are
struggling. &nbsp;The thing is, the good news does not have any
direct effect on the quality of life here in the USA, while the bad
news <i>does</i> have a direct domestic effect.
&nbsp;How bad the negative effect will be remains to be seen.
&nbsp;I'm not arguing that the economic news is dire; rather, I am
saying that this juxtaposition of events may highlight the relative
importance of the two. &nbsp;It is going to be hard for people to
care about an incremental improvement in Iraq, when their own
retirement funds are going in the tank.</div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114979266619990687'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114979266619990687'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/06/todays-lesson.html' title='Today's Lesson?'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry><entry><id>tag:blogger.com,1999:blog-6281085.post-114974738938794238</id><published>2006-06-08T02:10:00.000-04:00</published><updated>2006-06-08T02:16:29.823-04:00</updated><title type='text'>"They Must Actually Take Their Medication"</title><content type='html'><div id="Science">
A <a
href="http://www.medpagetoday.com/Endocrinology/Osteoporosis/tb2/3471?pfc=101&amp;spc=246">new
report</a> indicates that treatment with calcium and vitamin D
might actually reduce the incidence of hip fractures. &nbsp;This
appears to contradict some other studies that were reported widely in
the popular media. &nbsp;<br>
<blockquote>Dr. Boonen presented results of a meta-analysis of
major randomized placebo-controlled trials that analyzed the effects of
vitamin D alone or in combination with calcium. The meta-analysis found
that in patients getting 800 units of vitamin D and more than 1,000 mg
of calcium a day, there was a 21% reduction in risk of fracture
compared to placebo.<br>
</blockquote>
The new report was a <a title="Wikipedia link"
href="http://en.wikipedia.org/wiki/Meta-analysis"><i>meta-analysis</i></a>,
meaning that the authors pooled the results of several studies.
&nbsp;As seen in Wikipedia:<br>
<blockquote>In <a
href="http://en.wikipedia.org/wiki/Statistics"
title="Statistics">statistics</a>, a <b>meta-analysis</b>
combines the results of several studies that address a set of related
research hypotheses. The first meta-analysis was performed by <a
href="http://en.wikipedia.org/wiki/Karl_Pearson"
title="Karl Pearson">Karl Pearson</a> in 1904, in an
attempt to overcome the problem of reduced <a
href="http://en.wikipedia.org/wiki/Statistical_power"
title="Statistical power">statistical power</a> in
studies with small sample sizes; analyzing the results from a group
of studies can allow more accurate data analysis.</blockquote>
To give an idea of why the meta-analysis might be more valid than the
other studies, the authors point out:<br>
<blockquote>For one thing, he said, neither study had enough
statistical power to find an effect. For instance, he said, the RECORD
trial, looking at hip fractures, had 2,649 participants and only 93
events. By contrast, Dr. Boonen said, he and his colleagues had a
patient pool of 16,978 individuals and 812 fractures.<br>
</blockquote>
I'm not sophisticated enough with statistics to be able to give an
opinion of the validity of this particular analysis, and the report I
am citing here has not yet been subjected to peer review.
&nbsp;Therefore, the results are to be considered to be
preliminary. &nbsp;<br>
<br>
What is interesting is the list of reasons given, for why the
meta-analysis gives results that are different than the
previously-reported studies. &nbsp;It turns out that the positive
effect is seen only in those patients who actually had a deficiency of
either calcium or vitamin D. &nbsp;If the patient's regular diet
provides enough of those nutrients, there is no effect from
supplements. &nbsp; Some patients in the studies did not take doses
that were high enough. &nbsp;Some did not take both the calcium and
the vitamin D. &nbsp;Also, the prior reports included in the
analysis patients who did not actually take the supplements at all:<br>
<blockquote>Dr. Boonen told reporters after his presentation that
clinicians need to pay attention to four factors. They must prescribe a
combination of calcium and vitamin D, the doses must be high enough,
the patients must be in need of the supplements, and finally they must
actually take their medication.<br>
</blockquote>
It seems kind of obvious to say that the patients actually have to take
the supplements in order to see an effect, but in daily practice, noncompliance
turns out to be a common problem. &nbsp;Sometimes the factors that
seem too obvious to even consider, are the ones that turn out to be
important.</div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114974738938794238'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114974738938794238'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/06/they-must-actually-take-their.html' title='"They Must Actually Take Their Medication"'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry><entry><id>tag:blogger.com,1999:blog-6281085.post-114948416952699754</id><published>2006-06-05T01:09:00.000-04:00</published><updated>2006-06-05T01:09:29.560-04:00</updated><title type='text'>Is This One For Real?</title><content type='html'><div id="Science">
The LA Times (free registration required) has an article on the
possibility of a shortage of physicians in the USA:<br>
<blockquote><b><a
href="http://www.latimes.com/business/la-fi-doctors4jun04,0,1528090.story">Physician
Shortage Looms, Risking a Crisis, as Demand for Care Explodes</a></b><br>
<b><small>An aging America needs more doctors, but supply
isn't keeping up. Experts fear worsening quality and dangerously long
waits for appointments.</small></b><br>
<small>By Lisa Girion, Times Staff Writer<br>
June 4, 2006</small><br>
<br>
A looming doctor shortage threatens to create a national healthcare
crisis by further limiting access to physicians, jeopardizing quality
and accelerating cost increases.<br>
<br>
Twelve states &mdash; including California, Texas and Florida
&mdash; report some physician shortages now or expect them within a
few years. Across the country, patients are experiencing or soon will
face shortages in at least a dozen physician specialties, including
cardiology and radiology and several pediatric and surgical
subspecialties.<br>
<br>
The shortages are putting pressure on medical schools to boost
enrollment, and on lawmakers to lift a cap on funding for physician
training and to ease limits on immigration of foreign physicians, who
already constitute 25% of the white-coated workforce.<br>
<br>
But it may be too late to head off havoc for at least the next decade,
experts say, given the long lead time to train surgeons and other
specialists. [...]<br>
</blockquote>
The biggest issue there is the funding for medical training.
&nbsp;It is incredibly expensive to train physicians. &nbsp;I
recall that when I was in medical school, and students were complaining
about double-digit increases in tuition, one of the administrators told
us that our tuition only covered about one-third of the actual cost of
training. &nbsp;As an <a
href="http://www.med.umich.edu/medschool/facts_faces/index.htm#tuition">historical
aside</a>:<br>
<blockquote><a
href="http://www.flickr.com/photos/jyaroch/160615766/"><img
alt="First UM Medical building"
title="First UM Medical building"
src="http://static.flickr.com/47/160615766_2a0812a0ef_o.jpg"
align="right" border="0" height="86" width="120"></a>When
the Medical School first opened in 1850, students paid only a $10
registration or matriculation fee.<br>
<br>
By 1891, the matriculation fee was $10 for Michigan residents and $25
for students from out of state. Over the next 50 years, tuition rose
slowly until it was $250 in 1940. In the early part of the twentieth
century, students were required to pay laboratory and demonstration
fees totaling $136 over the four years. None of this takes into account
room and board. The average cost of room and board in 1893 was $3-$5 a
week; 1931: $12-15 a week. In 2003, tuition and fees for Michigan
residents were $20,526 (out of state, $31,526) and estimated living
expenses were $20,300 a year. Currently, the average student debt for
someone receiving an M.D. degree from the University of Michigan is
close to $100,000. <br>
</blockquote>
Medical schools are allowed to charge more for services, based upon the
recognition of the fact that training costs are high. &nbsp;But the
federal government has balked at these higher fees, so there have been
caps. &nbsp;This debatable policy has made it more difficult for
medical schools to expand enrollment.<br>
<br>
There have been dire warnings of physician shortages before, but this
time it seems more credible to me. &nbsp;The key factor is the fact
that the average age of the US population is increasing.
&nbsp;Obviously, older people require more doctoring than younger
people. &nbsp;But there is another factor:<br>
<blockquote>At the same time, younger male physicians and women
&mdash; who constitute half of all medical students &mdash; are
less inclined to work the slavish hours that long typified the
profession. As a result, the next generation of physicians is expected
to be 10% less productive, Edward Salsberg, director of the Assn. of
American Medical Colleges' Center for Workforce Studies, told a
congressional committee in May.<br>
</blockquote>
I expect that the trend toward fewer work hours will bring up some
controversy, and possibly some resentment. &nbsp;Some physicians
will be negatively judgmental about those who choose to work fewer
hours. &nbsp;Others will face pressures to delay their retirement.
&nbsp;At the same time, it will be increasingly difficult for
physicians to keep up-to-date with their skills and knowledge base.
&nbsp;Every hour spent on continuing education is an hour that is
not devoted to patient care. &nbsp;There is a risk that the demand
for more patient-care hours could lead to doctors devoting less time to
continuing education, which obviously would have a detrimental effect
on quality.<br>
<br>
It seems likely that the prediction of a shortage of physicians is
accurate. &nbsp;That will pose new challenges for physicians, in
terms of managing stress. &nbsp;It occurs to me as I write this,
that it may be desirable to make a point of educating medical students
about these pressures, and how to deal with them. &nbsp;As soon as
I figure out how to deal with them, I will post that information here. </div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114948416952699754'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114948416952699754'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/06/is-this-one-for-real.html' title='Is This One For Real?'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry><entry><id>tag:blogger.com,1999:blog-6281085.post-114945540600864470</id><published>2006-06-04T17:01:00.000-04:00</published><updated>2006-06-04T17:14:42.266-04:00</updated><title type='text'>What To Do On 6/6/6</title><content type='html'>There is still time to make your plans:

<br>
June 4, 2006<br>
<br>
HELL, Mich. -- They're planning a hot time in Hell on Tuesday.<br>
<br>
The day bears the date 6/6/06 -- abbreviated as 666, it is the "number of the beast" according to the Bible's Book of Revelation, often linked to the devil or the Antichrist.<br>
<br>
And there's not a snowball's chance in Hell the day will go unnoticed in the unincorporated hamlet 60 miles west of Detroit.<br>
<br>
Nobody seems more fired up than John Colone, the town's self-styled mayor and owner of a souvenir shop.<br>
<br>
''I've got '666' T-shirts and mugs. I'm only ordering 666 so once they're gone, that's it,'' said Colone, also known as Odum Plenty. ''Everyone who comes will get a letter of authenticity saying you've celebrated June 6, 2006, in Hell.''<br>
<br>
Not all 'Hell-billies' happy<br>
<br>
Most of Colone's wares will sell for $6.66, including deeds to one square inch of Hell.<br>
<br>
Mike ''Smitty'' Hickey, owner of Dam Site Inn, wasn't sure what kind of clientele would show up Tuesday.<br>
<br>
''I don't think we're going to get the cult crowd, the devil worshippers or anything like that,'' Hickey said.<br>
<br>
Jason LeTeff, one of the town's 72 year-round residents -- or, as the mayor calls them, Hellions or Hell-billies, wasn't enthused.<br>
<br>
''Now, here I am living in Hell, taking my kids to church and trying to teach them the right things and the town where we live is having a 6-6-6 party,'' he said.</blockquote>

issue final tolerance approval for 20 organophosphate and carbamate
pesticides. The scientists cite &ldquo;compelling
evidence&rdquo; which EPA leadership is choosing to ignore that
these &ldquo;pesticides damage the developing nervous systems of
fetuses, infants and children.&rdquo;<br>
<br>
Today&rsquo;s Wall Street Journal <a
href="http://www.peer.org/news/clips.php">article</a>
(subscription) broke the story and cites political pressure by agency
managers and pesticide-industry officials to allow the continued use of
a family of pesticides that might be harmful to children, infants and
fetuses. The letter asks EPA Administrator Stephen Johnson to either
adopt maximum exposure protections for these agents or take them off
the market.<br>
</blockquote>
It seems ironic that persons who advocate for a "culture of life" would
want to make it legal to poison fetuses. &nbsp;Of course, no one is
saying that these pesticides actually <i>kill</i> fetuses,
just that they damage their brains. &nbsp;The real irony is that it
is going to be a lot harder to keep up the supply of scientists and
science teachers, if we poison their developing brains.</div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114943995756746030'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114943995756746030'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/06/war-on-science-update.html' title='War on Science Update'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry><entry><id>tag:blogger.com,1999:blog-6281085.post-114937223473548790</id><published>2006-06-03T17:52:00.000-04:00</published><updated>2006-06-03T18:03:54.780-04:00</updated><title type='text'>Cheslea Painters Art Show</title><content type='html'>In Chelsea, Michigan, the <a href="http://www.chelseapainters.com/artfair/media.htm">Chelsea Painters</a> are having their annual art fair.

OK, this synopsis does not contain much actual information; certainly,
not enough to be useful as a basis for medical decisions. &nbsp;But
it
does provide an example to illustrate the process of skeptical
thinking. &nbsp;It's from Medscape News (free registration required

but it's worth the hassle).<br>
<blockquote><a
href="http://www.medscape.com/viewarticle/533557">Sildenafil
May Improve Sexual Functioning in Diabetic Women</a><br>
<blockquote>NEW YORK (Reuters Health) May 31 - Premenopausal
women with
type 1 diabetes with sexual dysfunction may find that sildenafil
improves arousal, orgasm and sexual enjoyment and decreases pain during
intercourse, results of a small pilot study suggest. [...]<br>
<br>
To test their theory, they recruited 32 women with type 1 diabetes who
in the past had experienced normal sexual desire within their
heterosexual relationship, but currently experienced sexual dysfunction
-- for 3.5 years on average. [...]<br>
<br>
Sildenafil was associated with significantly improved arousal, orgasm,
and enjoyment compared with baseline (p &lt; 0.001 for each).
Compared
with placebo, the experience of arousal (p &lt; 0.01) and orgasm (p
&lt; 0.05) were better during active treatment. Only desire and
frequency did not change significantly in either group. [...]<br>

Note: <a title="Wikipedia link"
href="http://en.wikipedia.org/wiki/Sildenafil" rel="tag">sildenafil</a>
is the generic name for <a title="manufacturer's site"

The original study can be found <a

have no other use for) in order to read the text.<br>
<br>
There are a couple of points that one needs to consider in interpreting
a study such as this. &nbsp;First, as a general rule, one should
not make medical decisions based upon small studies that are identified
as pilot studies. &nbsp;Doing so, one is likely to expose patients
to risks that have not been justified by sufficient research. <br>
<br>
Second, it is important to examine critically the outcome measures used
in the study. &nbsp;Specifically, it is necessary to look beyond
the measures of statistical significance. &nbsp;The statistics in
this study look reasonably impressive, at first glance.
&nbsp;However, those numbers do not tell you what you really want
to know. &nbsp;Remember, <i>statistical</i>
significance does not necessarily translate into <i>clinical</i>
significance. &nbsp;<br>

<br>
To be fair, the authors of the paper are cautious about interpreting
the numbers. &nbsp;They include all the appropriate cautions and
limitations. &nbsp;My concern is that a newspaper could easily pick
up this story and print the high points, leading to a great deal of
misinterpretation among the general public. &nbsp;<br>
<br>
When I get around to it, I'll put up another post with my
interpretation of the numbers. &nbsp;In the meantime medical
students and interested readers are encouraged to look at the data and
think about what conclusions may be justified by the numbers.<br>

When DSM-V is published, it will expand the list of symptoms of
caffeine intoxication:<br>
<ul>
<li>Excessive use of unordered lists and bullet points</li>
<li>Gross failure to comply with social norms of HTML coding</li>
<li>Implusive, pointless linking from one post to another</li>
<li>Pathological refusal to use tags only for their intended

This is a good illustration of an important point reagrding the
categorization of medical conditions (<a

&nbsp;When the expectations and demands of society change, we have

This is not really big news, but it makes me stop and think. &nbsp;<a

href="http://en.wikipedia.org/wiki/Escitalopram" rel="tag">Escitalopram</a>
has been approved in generic form (5, 10, 20mg tabs, 5mg/5ml solution).
&nbsp;Previously, it could only be obtained as the branded product,
Lexapro. &nbsp;As of today, that leaves only one selective
serotonin reuptake inhibitor (<a title="Wikipedia link"
href="http://en.wikipedia.org/wiki/SSRI" rel="tag">SSRI</a>)
with patent protection: Zoloft (<a title="Wikipedia link"
href="http://en.wikipedia.org/wiki/Sertraline" rel="tag">sertraline</a>).
&nbsp;Zoloft is going off patent in June 2006. &nbsp;<br>
<br>
I'm still not entirely sure when generic sertraline will be available.
&nbsp;There has been a lot of convoluted legal wrangling over the
subject, a discussed in <a
href="http://www.ftc.gov/ogc/briefs/050208teva.pdf">this
court ruling</a> (82 KB PDF). &nbsp;When it does occur,
though, there will be no SSRIs under patent protection.
&nbsp;Effexor (<a title="Wikipedia link"

and Cymbalta (<a title="Wikipedia link"
href="http://en.wikipedia.org/wiki/Duloxetine" rel="tag">duloxetine</a>)
will be the only popular antidepressants that are patented.
&nbsp;(The Emsam (<a title="Wikipedia link"

patch was <a
href="http://www.fda.gov/bbs/topics/NEWS/2006/NEW01326.html">approved
recently</a>, but it remains to be seen how popular it will turn
out to be.)<br>
<br>
For many years, antidepressants have been a major contributor to the
cost of prescription drug insurance coverage. &nbsp;Clearly, that
is changing. &nbsp;<br>
<br>
I suppose we can all expect our insurance to get cheaper now.</div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114887480886263509'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114887480886263509'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/05/generic-escitalopram.html' title='Generic Escitalopram'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry><entry><id>tag:blogger.com,1999:blog-6281085.post-114885977269194789</id><published>2006-05-28T19:40:00.000-04:00</published><updated>2006-05-28T19:42:52.766-04:00</updated><title type='text'>On the Recursive Nature of Pride</title><content type='html'>Pride is one of the seven deadly sins. &nbsp;The others are greed
and sloth and a few others I can't remember. &nbsp;Pride is the one
I remember best, because of its curious mathematical properties.
&nbsp;Things with unexpected properties are easier to remember than
ordinary things like greed and sloth and so forth.<br>

<br>
The thing about pride is this: once a person becomes aware of it, he or
she tends to recognize that it is a sin. &nbsp;That person then
takes steps to banish the pride. &nbsp;Then the person is proud for
having banished the sin, thus becoming a paragon of virtue.
&nbsp;Rather naturally, the person then realizes that excessive
pride in one's own virtue is itself a sin. &nbsp;Then the whole
thing starts over again.<br>
<br>
Some people do manage to get&nbsp;little bit wiser with each
iteration. &nbsp;Others do not.<br>
<br>
I have never been able to figure out what makes the difference.
&nbsp;Nor have I been able to find an objective way to determine if
I am one of the ones who is getting wiser.<br>

designed a new banner. &nbsp;(I had help with the techincal
aspects, but the design was my idea.) &nbsp;I'm a little worried
that they are redesigning the layout, so it is possible that the size
will be wrong or the colors won't match, but I decided to do it anyway.
&nbsp;It should be simple enough to change, if that turns out to be
necessary.<br>
<br>
The <a
href="http://en.wikipedia.org/wiki/Wikipedia:Picture_of_the_day/March_21%2C_2006">image
on the left</a> is a macro photo of an Intel 486-DX2 processor;
the <a href="http://www.bartleby.com/107/illus720.html">image
on the right</a> is an illustration from the 1918 edition of
Gray's Anatomy. &nbsp;Both are in the public domain. &nbsp;I
found the images on Wikipedia. &nbsp;The text is in a font known as
Ringbearer, which I downloaded from a free font site. &nbsp;I
suppose I should mention the site, but I can't recall the name of the
site. &nbsp;If you search for "Ringbearer font" you will find
several sites that have it.<br>
<br>
The banner was made using <a href="http://www.gimp.org/">GIMP</a>,
the Gnu Image Processor, which is an open-source program.
&nbsp;Although it started as a Linux program, there are version for
Mac and Windows.<br>

prior posts on the topic, or if you already are familiar with the
concept of a live CD, just skip to <a href="#The_bottom_line">the
bottom line</a> for the info that is specific to Accelerated
Knoppix. &nbsp;<br>
<blockquote>&nbsp;&nbsp;&nbsp; We affirm that the
world's magnificence<br>
&nbsp;&nbsp;&nbsp; has been enriched by a new beauty:<br>
&nbsp;&nbsp;&nbsp; the beauty of speed.<br>
<br>
Filippo Tommaso Marinetti - Manifesto of Futurism -<br>
</blockquote>
That quote is on the <a
href="http://www.alpha.co.jp/biz/rdg/ac-knoppix/index_en.html">homepage</a>
for the Accelerated <a rel="tag"
href="http://distrowatch.com/table.php?distribution=knoppix">Knoppix</a>
project. &nbsp;What that means is that computer users
can boot from the CD and get a complete operating system and a complex
set of applications, ready to use. &nbsp; It boots if the hard
drive has crashed. &nbsp;It even boots if there is no hard drive
in the computer at all. &nbsp;<br>
<br>
There are several uses for a <a title="Wikipedia link"
href="http://en.wikipedia.org/wiki/Live_CD">live CD</a>.
&nbsp;Probably the most
obvious is that it enables a user to try an operating system or an
application without having to install the application on the hard
drive. &nbsp;So if you've never used <a title="Wikipedia link"
href="http://en.wikipedia.org/wiki/Linux">Linux</a>
before, and want to give
it a try, you can use alive CD to try it out, with minimal effort, and
with no risk of messing anything up. &nbsp;Or, if you've heard
about OpenOffice -- the free alternative to Microsoft Office -- and
want to see if it
really will open your Word documents, and see if it really is as easy
to use as Microsoft Word, you can do so easily. &nbsp;<br>
<br>
Another use for a live CD is for emergency use. &nbsp;If your
computer crashes and you HAVE TO check your email, you can do it
quickly with a live CD. (It can't configure a dial-up connection
automatically, but it can and will recognize and use a broadband or
ethernet connection without specific user intervention.)
&nbsp;Likewise, if your system won't boot,
you might be able to recover data using a live CD. &nbsp;<br>
<br>
A more obscure use of a live CD could be to use it for anonymous
browsing. &nbsp;<a
href="http://www.lxnaydesign.net/index.php?option=com_content&amp;task=view&amp;id=190&amp;Itemid=2">lxnay
dEsigN</a> is planning to develop a live CD (actually a DVD) that
uses <a title="Wikipedia link"
href="http://en.wikipedia.org/wiki/Tor_%28anonymity_network%29"
rel="tag">TOR</a> servers to obscure your internet
usage. &nbsp;Plus, being on an unwritable medium, there would be no
cookies, no browsing history, or other traces that could be recovered
later.<br>
<br>
Finally, some folks have used Knoppix to figure out how to configure
their Linux systems. &nbsp;I've done that myself. &nbsp;When I
was first learning to do intermediate-level configuration, I somehow
messed up my XF86Config file (one of the files that says "Please do not
edit this file" at the top.) &nbsp;I booted from Knoppix and saw
how Knoppix autoconfigured the file, saved it to a USB flash drive, and
fixed the problem that way.<br>
<br>
By the way, there are live CD's for <a
href="http://en.wikipedia.org/wiki/Live_CD#List_of_live_CDs">operating
systems other than Linux</a>. &nbsp;I've never used any of
them, though. &nbsp;<br>
<br>
<a name="The_bottom_line"></a>The bottom line: one
disadvantage of a live CD is that it can take a couple of minutes to
boot. &nbsp;Accelerated Knoppix uses a <a
href="http://www.alpha.co.jp/biz/rdg/ac-knoppix/index_en.html#notes2">new
technology</a> to speed up the boot process. &nbsp;I did not
time it, but it seemed to boot in less than a minute. &nbsp;<br>
<br>
<div align="center"><a

alt="Accelerated Knoppix" height="340" width="490"></a><br>
</div>
<br>
In the spirit of open-source software, the developers of Acclerated
Linux have made available their <a
href="http://www.alpha.co.jp/biz/rdg/ac-knoppix/index_en.html#download">"LCAT"
(Live CD Acceleration Toolkit)</a>. &nbsp;If you want to
convert your favorite Live CD distro to an accelerated version.
&nbsp;<br>
<br>
The one trick to this distribution is that the default language is
<i>Japanese</i>. &nbsp;In order to get English menus,
you have to type&nbsp; <code>Knoppix
lang=US</code> &nbsp;when it first starts. <br>
<br>
So, I will now keep a copy of this at home and at my various offices,
just for emergency recovery.

It was publicized pretty well, when the Administration <a

taxes on teenagers</a>. &nbsp;This has been discussed

however, that there has been another tax increase, again affecting
Americans who have little influence. &nbsp;And like the one that

<blockquote><a
href="http://www.iht.com/articles/2006/05/26/business/tax.php">U.S.
tax law sends expatriates reeling</a><br>
By Keith Bradsher and David Cay Johnston <br>
The New York Times<br>
<br>
FRIDAY, MAY 26, 2006<br>
<br>
HONG KONG The sudden, and retroactive, imposition by the U.S. Congress
last week of much higher taxes on Americans living abroad has left
individuals and companies scrambling to regroup, while many executives
and entrepreneurs assert that the move could backfire by hurting U.S.
business interests at home and abroad.<br>
&nbsp;<br>
The $69 billion tax cut signed into law May 17 raises taxes on
Americans living overseas by $2.1 billion over the coming decade. [...]<br>
</blockquote>
To put this in perspective, consider that the additional revenue
represents <a
href="http://www.usatoday.com/news/world/iraq/2003-09-07-cover-costs_x.htm">the
cost</a> of only a two weeks of fighting the war in Iraq (which
does not include reconstruction costs).
&nbsp;If it hurts international trade, it obviously wouldn't be
worth it. &nbsp;<br>
<br>
Note that this increase is not only a violation of one of Bush's
campaign pledges, but it also increases the complexity of the tax code:<br>
<blockquote>Last year the law allowed most overseas Americans to
exclude $80,000 of foreign earned income from income taxed in the
United States. The new law adjusts the exclusion for inflation to
$82,400, but it raises taxes by adding complex new provisions on how
the exclusion is calculated.&nbsp;<br>
</blockquote>
Oddly, this article shows up on the <i>International Herald
Tribune</i> site, but not on the <i>New York Times</i>
website, despite the fact that it was written by NYT reporters.

Speech to Medical Graduates, Bloomberg Diverges From G.O.P. Line</a><br>
By DIANE CARDWELL<br>
Published: May 26, 2006<br>
<br>
Distancing himself from national Republicans and the Bush
administration, Mayor Michael R. Bloomberg yesterday urged an end to
the political manipulation of science, which he said had been used to
discredit the threat of global warming and undermine medical
advancements in areas like stem-cell research.<br>
<br>
In a speech to graduating students of Johns Hopkins University School
of Medicine in Baltimore, Mr. Bloomberg railed against what he sees as
ideologically motivated arguments that have fueled debate over
hot-button issues like teaching evolution in public schools and the
Terri Schiavo case.<br>
<br>
"Today, we are seeing hundreds of years of scientific discovery being
challenged by people who simply disregard facts that don't happen to
agree with their agenda," Mr. Bloomberg said. "Some call it
pseudoscience, others call it faith-based science, but when you notice
where this negligence tends to take place, you might as well call it
'political science.' " [...]<br>
</blockquote>
Bloomberg only cited global warming, stem cells, Terri Schiavo, and
Intelligent Design. &nbsp;There is a lot more that he could have
mentioned, but I am sure the new graduates appreciate the fact that he
didn't go on at encyclopedic length.<br>
<br>
In his speech, Bloomberg clearly acknowledged the systematic nature of
the war on science. &nbsp;<br>
<br>
From time to time, I have wondered, momentarily, if scientists are
defensive about their field, <i>imagining</i> they are
under attack, much as a subset of conservative Christians feel there is
a war on Christmas. &nbsp;I never think that for more than a few
seconds, though. &nbsp;<br>
<br>
At other times, I wonder why scientists worry about the war on science.
&nbsp;After all, science will endure. &nbsp;Presidents come and
go, religions come and go, but science marches on. &nbsp;Surely
scientists can find other things to work on, at those times that petty
power struggles give rise to temporary impediments. &nbsp;Then,
when the heat dies down, they can get back to whatever it was that the
politicians or theocrats were meddling in.<br>
<br>
But then I remember that science is actually <i>important, now</i>.

From Nature News, we hear of another twist in the story of inheritance:<br>
<br>
<blockquote><a
href="Mutant%20mice%20challenge%20rules%20of%20genetic%20inheritance">Mutant
mice challenge rules of genetic inheritance</a><br>
DNA's cousin, RNA, may also pass information down the generations.<br>
<br>
Helen Pearson<br>
<br>
In a discovery that rips up the rulebook of genetics, researchers in
France have shown that RNA, rather than its more famous cousin DNA,
might be able to ferry information from one generation of mice to the
next.<br>
<br>
DNA has long been credited with the job of passing traits from parent
to child. Sperm and egg deliver that DNA to the embryo, where it
ultimately decides much of our looks and personality.<br>
<br>
The new study in Nature1 thrusts RNA, DNA's sidekick, into the
limelight. It suggests that sperm and eggs of mammals, perhaps
including humans, can carry a cargo of RNA molecules into the embryo -
and that these can change that generation and subsequent ones.<br>
<br>
"It's a very exciting possibility," says Emma Whitelaw who studies
patterns of inheritance at Queensland Institute of Medical Research in
Brisbane, Australia. "DNA is certainly not all you inherit from your
parents." [...]</blockquote>
We already knew that mitochondrial DNA could play a role, albeit a
small <br>
role, in the process of inheritance. &nbsp;<br>
<br>
<a href="http://news.bbc.co.uk/1/hi/sci/tech/5011826.stm">
Spotty mice flout genetics laws</a>, on the BBC site, is another
article on the same topic. &nbsp;The Washington Post has a version,
<a
href="http://www.washingtonpost.com/wp-dyn/content/article/2006/05/25/AR2006052501785.html">here</a>.
&nbsp;<br>
<br>
When I hear of things like this, I am reminded of how little we know
about the details of the functioning of even fairly simple processes in
biology. &nbsp;Think about inheritance, which is the transfer of a
defined set of information. &nbsp;Then think about the operation of
the human brain, which has something like 10<small><sup>15</sup></small>
synaptic connections. &nbsp;<br>
<br>
Now, I am going to write something very un-scientific. &nbsp;<br>
<br>
Proponents of Intelligent Design might look at the subtleties of
inheritance, or the vast complexity of the brain, and take those
observations as evidence for their proposition. &nbsp;As far as I
can tell, though, their only argument is that the origin of species via
evolution just doesn't <i>seem</i> right; it doesn't mesh
with their intuition. &nbsp;My intuition apparently works
differently. &nbsp;What I see is that scientists start out with a
bunch of complex, seemingly-inexplicable phenomena, then one by one,
make discoveries that explain more and more of what previously was
inexplicable. &nbsp;What my intuition tells me is that, eventually,
science will come up with mundane (complex, perhaps, but still mundane)
explanations for an ever-increasing percentage of things that formerly
were awe-inspiring. &nbsp;From that, I conclude that the mere
existence of seemingly-miraculous things can only be taken as evidence
of limitation in our knowledge and understanding. &nbsp;It does not
mean anything more.</div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114861524291119356'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114861524291119356'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/05/nature-is-full-of-surprises.html' title='Nature is Full of Surprises'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry><entry><id>tag:blogger.com,1999:blog-6281085.post-114853299254311884</id><published>2006-05-25T00:44:00.000-04:00</published><updated>2006-05-25T00:58:57.986-04:00</updated><title type='text'>Nice Picture</title><content type='html'><div id="Science">

I suppose that one tires of all the fancy do-dads after a while.
&nbsp;Or maybe it is just a desire for something different.
&nbsp;After all, different things always have a certain appeal.<br>

Speaking of that appeal, it has been determined that we now have a
"new"

<blockquote><a

By John Lichfield in Paris<br>
Published: 24 May 2006<br>
<br>
In a world full of disappearing or threatened species, here is some
good news at last. The planet is about to welcome a new species of
penguin.<br>
<br>
The birds - a few thousand small penguins on the French islands of
Amsterdam and St Paul in the southern Indian Ocean - resemble millions
of rockhopper penguins found all around the northern fringe of the
Antarctic.<br>
<br>
And thanks to the stubborn research of a French ornithologist, they
have been declared a species in their own right.<br>
<br>
Pierre Jouventin, scientist and film-maker and one of the world's
foremost experts on penguins, first claimed that the Amsterdam and St
Paul rockhoppers were a separate species 25 years ago. [...]<br>
<br>
His claims were dismissed by other ornithologists. Now, two years
before his retirement, Mr Jouventin, 63, has been vindicated. In a
forthcoming article in the magazine Molecular Ecology he will reveal
DNA tests which show that the Amsterdam and St Paul rockhoppers are a
distinct species. [...]<br>

Botox for Depression?</title><content type='html'><div id="Science">
Medscape News has an interesting item: <a
href="http://www.medscape.com/viewarticle/532355"><i>Botox
Injections May Be Useful for Major Depression</i></a> (free
registration required).<br>
<blockquote><b>Botox Injections May Be Useful for Major
Depression</b><br>
Laurie Barclay, MD<br>
<br>
May 16, 2006 &mdash; Botulinum toxin A injections can treat major
depression, according to the results of a small case series reported in
the May issue of Dermatologic Surgery.<br>
<br>
"Major depression is a common and serious disease that may be resistant
to routine pharmacologic and psychotherapeutic treatment approaches,"
write Eric Finzi, MD, PhD, and Erik A. Wasserman, PhD, from Dermatology
and Cosmetic Surgery Associates in Greenbelt, Maryland, and Chevy Chase
Cosmetic Center in Maryland. "There is a body of evidence that suggests
that the facial expression of emotion may play a causal role in the
subjective experience of emotion. We initiated a small open pilot trial
to determine whether inhibiting the expression of facial frowning
commonly associated with depression could help ameliorate depressive
symptoms."<br>
</blockquote>
This was an extremely small study, involving only ten patients,
without, and with double- or single-blind condition. &nbsp;That
means that it is not possible to draw any valid conclusions, other that
to say that a larger, double-blind, placebo-controlled study might be
worthwhile. &nbsp;<br>
<br>
The idea is not without precedent. &nbsp;It is known that people
with anxiety tend to be overly vigilant concerning somatic symptoms
that are correlated with anxiety. &nbsp;When they notice such
symptoms, it tends to increase their anxiety, which increases the
symptoms: a classic positive feedback loop. &nbsp;Sometimes,
patients with anxiety disorders can learn to interrupt the feedback
loop, resulting in clinical improvement. &nbsp;As far as I know,
nobody has tried anything like that with mood disorders, until now.<br>
<blockquote>A total of 10 patients who met Diagnostic and
Statistical Manual of Mental Disorders, Fourth Edition, criteria for
ongoing major depression refractory to pharmacologic or
psychotherapeutic treatment were evaluated with the Beck Depression
Inventory II (BDI-II) before receiving botulinum toxin A to their
glabellar frown lines.<br>
<br>
Two months later, all patients were reevaluated clinically and with the
BDI-II. Nine of 10 patients were no longer depressed, and the 10th
patient had an improvement in mood.<br>
<br>
"These findings are very promising and show that Botox has the ability
to work in ways we don't expect," Alastair Carruthers, MD,
president-elect of the American Society for Dermatologic Surgery and
head of Carruthers Dermatology in Vancouver, British Columbia, Canada,
says in a news release.<br>
</blockquote>
Personally, I would be astonished if this turned out to work in a
large, randomized, double-blind, placebo-controlled study. &nbsp;On
the other hand, it would be pretty neat if it did work. &nbsp;What
is more likely is that it either will not pan out at all; or it will
turn out to be of great benefit to a few people, partial benefit to a
few more, and no benefit to everyone else. &nbsp;Even so, stranger
things have happened. &nbsp;The first discovery of <a
title="Wikipedia link"
href="http://en.wikipedia.org/wiki/Antidepressants" rel="tag">antidepressant</a>
medication occurred when an antitubercular antibiotic, iproniazid, <a
title="Medscape link"
href="http://www.medscape.com/medline/abstract/11478422?queryText=iproniazid%20depression">was
found</a> to relieve melancholia in patients being treated for
tuberculosis. &nbsp;<br>
<br>
None of this indicates that <a title="Wikipedia link"
href="http://en.wikipedia.org/wiki/Botox" rel="tag">Botox</a>
is likely to work for treatment of depression, but it shows that it is,
at least, remotely possible.<br>
<br>
Update: The Washington Post <a
href="http://www.washingtonpost.com/wp-dyn/content/article/2006/05/20/AR2006052000979.html">picked
up the story</a>, and has a testimonial from one patient.
&nbsp;From a scientific standpoint, one testimonial is meaningless.
&nbsp;What it does do, though, is give you an idea of what the
experience is like from the patient's point of view.</div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114818633229301839'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114818633229301839'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/05/huh-botox-for-depression.html' title='Huh?

This is sort of &nbsp;a follow-up to a <a
href="http://corpus-callosum.blogspot.com/2006/05/neurogenesis-promoted-by-fluoxetine.html">recent
post</a>,
in which I discussed the correlation between administration of
fluoxetine, and neurogenesis in the hippocampus. &nbsp;In that
post, I
mentioned that skeptics of psychopharmacology are fond of pointing out
the lack of a well-defined connection between the inhibition of
serotonin reuptake, and the clinical effects of the serotonin reuptake
inhibitors. &nbsp;<br>
<br>
The hypothesis that there is a connection between serotonin and
depression is a refinement of the monoamine hypothesis of depression.
&nbsp;That hypothesis states that there may be a connection between
relative underactivity of brain monoamines (serotonin, norepinepherine,
dopamine) and depression. &nbsp;It is an old idea, derived in part
from studies such as this one: &nbsp;Antagonism to reserpine
induced depression by imipramine, related psychoactive drugs, and some
autonomic agents<i>.</i> &nbsp;Sigg EB, Gyermek L, Hill
RT.&nbsp;<i>Psychopharmacologia</i>. 1965 Feb
15;7(2):144-9.<br>
<br>
Obviously, we have learned a lot since 1965, so the monoamine
hypothesis is significant mainly as an historical relic. &nbsp;Even
the refinement -- the serotonin hypothesis -- is ancient.
&nbsp;Since then, ample evidence has been found, showing that the
serotonin hypothesis is, at best, a gross oversimplification.
&nbsp;There is no strict correlation between serotonin activity and
any defined mental illness.<br>
<br>
The lack of a strict correlation means that the action of
antidepressant
medication is not fully understood; nobody I know will dispute that.
But the thing is, harping on that string is pointless. &nbsp;It is
like
pointing out that there is not a strict correlation between the noise
of an automobile engine, and the motion of he automobile. &nbsp;It
is
true that sometimes an automobile moves without the engine making
noise; and sometimes the engine makes noise without moving.
&nbsp;Sometimes there is a significant lag between the time the
engine
starts making noise, and the time the automobile starts to move.
&nbsp;With the correct instruments, it would even be possible to
show
that
none of the energy that goes into the production of noise has anything
to do with the movement of the automobile. &nbsp;True, all of it.
&nbsp;But can we conclude that there is no connection between the
noise
of the automobile, and the motion? &nbsp;<br>
<br>
Perhaps the serotonin boost is not at all related to the clinical
effect. &nbsp;It could be an&nbsp;<a title="Wikipedia link"
href="http://" rel="tag">epiphenomenon</a>.
&nbsp;Physicians generally know about epiphenomena, and are
cautious about overinterpreting them. &nbsp;Pointing out the fact,
that there is not necessarily a causal connection, is tiresome.
&nbsp;Thus, when a skeptic takes pains to point it out, it merely
shows that the skeptic is not aware of how obvious it is to
medically-educated people.<br>
<br>
As an aside, it occurs to me that epiphenomena are roughly analogous to
<a title="Wikipedia link"
href="http://en.wikipedia.org/wiki/Spandrel">spandrels</a>.
&nbsp;If I felt like getting tediously philosophical, I could write
a post outlining that analogy. &nbsp;Another time, perhaps.
&nbsp;(A hint: just as a feature that evolves as a spandrel can
turn out to be useful, sometimes side effects of mediation can be
useful.)<br>
<br>
Sometimes it is difficult to avoid getting tediously philosophical.
&nbsp;Oh well. &nbsp;It occurs to me also that this is an
example of how a good understanding of evolutionary theory can be
helpful in understanding medicine, as Orac is <a
href="http://scienceblogs.com/insolence/2006/03/medicine_and_evolution_part_i.php">fond
of pointing out</a>. &nbsp;(As is my former residency
director, <a
href="http://www.sciencemag.org/cgi/content/summary/311/5764/1071?maxtoshow=&amp;HITS=10&amp;hits=10&amp;RESULTFORMAT=&amp;fulltext=medicine+needs+evolution&amp;searchid=1&amp;FIRSTINDEX=0&amp;resourcetype=HWCIT">Randy
Nesse</a>.) &nbsp;This is true regardless of whether you
believe that evolution is responsible for the origin of species.<br>
<br>
Putting that aside aside, and getting back to the point: Because it is
tiresome to hear skeptics harp on that string (the lack of a
fully-delineated connection between serotonin and depression) I was
surprised to see this article in a well-regarded journal:<br>
<a
href="http://medicine.plosjournals.org/perlserv?request=get-document&amp;doi=10.1371/journal.pmed.0020392"><i>Serotonin
and Depression: A Disconnect between the Advertisements and the
Scientific Literature</i></a>, by Jeffrey R. Lacasse and
Jonathan Leo.<br>

</div>
<br>
I was surprised to see this, because it is, to me, a new twist on the
old theme. &nbsp;The authors do not imply that antidepressant
medication does not work; nor do they argue that psychopharmacology is
suspect. &nbsp;<br>
<blockquote>To equate the impressive recent achievements of
neuroscience with support for the serotonin hypothesis is a mistake.<br>
</blockquote>
Rather, they argue that it is inappropriate for pharmaceutical
companies to base advertising campaigns upon the presumed link between
serotonin and depression. &nbsp;<br>
<blockquote>In the US, the FDA monitors and regulates <acronym
title="direct-to-consumer advertising">DTCA</acronym>.
The FDA requires that advertisements &ldquo;cannot be false or
misleading&rdquo; and &ldquo;must present information that is
not inconsistent with the product label&rdquo; [27]. Pharmaceutical
companies that disseminate advertising incompatible with these
requirements can receive warning letters and can be sanctioned. The
Irish equivalent of the FDA, the Irish Medical Board, recently banned
GlaxoSmithKline from claiming that paroxetine corrects a chemical
imbalance even in their patient information leaflets [29]. Should the
FDA take similar action against consumer advertisements of SSRIs?<br>
</blockquote>
Curiously, the authors devote several paragraphs to debunking the
serotonin hypothesis, even though, in my opinion, their purpose could
have been served with one or two citations. &nbsp;What is even more
curious is that they do not go on to draw a specific conclusion that
answers the question they pose: they never answer directly the question
about whether the FDA should take action against the pharmaceutical
companies that refer to the serotonin hypothesis in their
advertisements. &nbsp;<br>
<br>
In fact, they do make a good case against the pharmaceutical companies,
and I happen to agree. &nbsp;It appears to be true, based upon
their argument, that pharmaceutical companies are not following FDA
regulations regarding DTC advertisements. &nbsp;Moreover, the
authors make several other good points, such as this one:<br>
<blockquote>Patients who are convinced they are suffering from a
neurotransmitter
defect are likely to request a prescription for antidepressants, and
may be skeptical of physicians who suggest other interventions, such as
cognitive-behavioral therapy [<a
href="http://medicine.plosjournals.org/perlserv?request=get-document&amp;doi=10.1371/journal.pmed.0020392#JOURNAL-PMED-0020392-B48">48</a>],
evidence-based or not.<br>
</blockquote>
I personally have spent a lot of time in the office, with patients,
trying to undo the misinformation contained in DTCA. &nbsp;It
bothers me that I have to do that. &nbsp;I would much rather spend
the time providing good education, not undoing bad education.
&nbsp;I would prefer to not have to deal with direct-to-consumer
advertising at all; but if we have to have it, companies really ought
to be held to the standards that exist to ensure balance and accuracy.</div></content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114816542652747583'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6281085/posts/default/114816542652747583'/><link rel='alternate' type='text/html' href='http://corpus-callosum.blogspot.com/2006/05/serotonin-and-depression-disconnect.html' title='Serotonin and Depression: A Disconnect'/><author><name>: Joseph j7uy5</name><uri>http://www.blogger.com/profile/12806669663107445151</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVJBzauYzPUXYT0CJ_mAitRBt8G2SDKkcSagvAIpSw_EcqJl25b8N1K8POIiJiWSnjyddZqzRGp4FbixU8DgRDf7TP7ZJuGSsKRZIM0DQbfGclkbqiZ1kNiJKeUs1ylA/s220/j7uy5.jpg'/></author></entry><entry><id>tag:blogger.com,1999:blog-6281085.post-114810689413182953</id><published>2006-05-20T02:32:00.000-04:00</published><updated>2006-05-20T02:34:54.176-04:00</updated><title type='text'>Impeachment Update</title><content type='html'><div id="Politics">
Howard Kurtz, <a
href="http://www.washingtonpost.com/wp-dyn/content/linkset/2005/04/11/LI2005041100587.html">writing</a>
on the <i>Washington Post</i> column, <i>Media Notes</i>,
has an update on the brewing impeachment issue. &nbsp;It turns out
that some Republican strategists have been hyping the threat of
impeachment. &nbsp;Apparently, they believe that the possibility of
impeachment of the President might motivate some voters to go to the
polls and vote for Republican congressional candidates.<br>
<br>
Personally, I do not see the problem with impeachment hearings, even
looking at it from the Republican perspective. &nbsp;After all,
with regard to the domestic spying operations, the Administration keeps
telling us that if we haven't done anything wrong, we have nothing to
fear. &nbsp;Certainly, the same principle applies to the
Administration itself.
