Text of the page (random words):
e latter is an empirical presumption about group averages in measurable traits someone with an iq of 80 is as human as someone with an iq of 120 and this is so regardless of whether the average iq of one race is different from that of another what worries people like those in the times story is that racial differences in iq or other traits seem to lend empirical support to racist theories but those theories are qualitatively wrong so that no empirical evidence could make them right if all individuals are of equal dignity and worth regardless of iq then a group is not fundamentally superior or inferior to another group by virtue of differences in average iq it seems that some very smart people mistakenly think that intelligence is a measure of fundamental worth maybe they re a little too

the influence of world war i on heart surgery posted by sydney on 11 11 2007 12 25 00 pm 0 comments saturday november 03 2007 a word about mrsa i ve been fielding a lot of doorknob questions about mrsa lately doorknob questions questions thrown out just as my hand reaches the doorknob to leave the room little wonder it s been in the news again and again and has even prompted the closing of schools and cancelling of football games despite what some editorialists say it is being framed as a threat to our children here s an example of the typical coverage a 16 year old springfield high school junior remained in serious condition friday in the intensive care unit of akron children s hospital with a drug resistant staph infection michael forester of lakemore was hospitalized oct 24 and was to undergo surgery friday said his mother mary baxter the more prayers i can get the better baxter said friday at the hospital on wednesday springfield school superintendent william stauffer in a letter sent to parents acknowledged that a student had become ill and was admitted to the hospital the superintendent said rumors that the student has a contagious disease that puts other students at risk and that the high school has an ongoing problem with staph infections are not true stauffer could not be reached for comment friday what is this mrsa a better question might be what is sa the sa in mrsa is staphylococcus aureus a bacteria that resides in our nasal passages and skin that is its habitat normally it causes us no problem but if conditions are right it can make us quite ill it s often the culprit behind boils and styes and cellulitis and urinary tract infections it can also cause more serious infections such as pneumonia as in the case of the young man in the linked to article above meningitis sepsis endocartditis and osteomyelitis it is one of the most common causes of sepsis penicillin conquered staph infections for a little while but the bacteria acquired resistance within a few years of the antibiotic s introduction when penicillin became widely used in the community the population of staph aureus living in noses and on skin shifted toward those containing an enzyme that could cut the betalactam ring on penicillin rendering it ineffective new antibiotics were developed to get around this one of those antibiotics was methicillin which brings us to the mr part of mrsa we don t use methicillin any longer we use drugs like augmentin instead but when we say that a staph aureus infection is methicillin resistant we mean that it s resistant to all penicillins even those that were developed to get around the betalactam eating defenses of the staph aureus population this doesn t mean that it s resistant to all antibiotics however just the ones that we typically use for a staph infections in the hospital we often use vancomycin for mrsa infections in the outpatient setting we use drugs like bactrim and clindamycin in most cases the infections respond nicely to these drugs there is however concern that the bacteria may one day develop resistance to these too as we use them more to treat the growing resistant population of staph so here are the take home points about mrsa 1 it isn t running amok in our schools like the blob or killer tomatoes it s living on our skin and nasal passages just as it always has before it developed resistance to penicillin and its cousins 2 one of the reasons bacteria acquire resistance is because we expose them to antibiotics when we don t need to don t insist on an antibiotic for every runny nose even if the snot is yellow and don t insist on one of the special antibiotics for mrsa for every pimple or pustule or red scratch if we overuse our remaining effective antibiotics we ll only end up with a population of staph aureus that is resistant to those too 3 don t freak out if you or your child develops a skin infection most staph infections are easily treatable even most mrsa infections are easily treatable 4 when you read the newspaper always remember that they lean to the dramatic in all things it makes for more entertaining reading posted by sydney on 11 03 2007 07

comments lies damned lies and well you know the new york times is parsing rudy guiliani s prostate cancer statitistics i had prostate cancer five six years ago mr giuliani a republican presidential candidate said in a speech that has been turned into the radio commercial my chance of surviving prostate cancer â and thank god i was cured of it â in the united states eighty two percent my chance of surviving prostate cancer in england only 44 percent under socialized medicine the office for national statistics in britain says the five year survival rate from prostate cancer there is 74 4 percent and doctors also say it is unfair to compare prostate cancer statistics in britain with those in the united states because in the united states the cancer is more likely to be diagnosed in its early stages certainly if you intensively screen for prostate cancer you will find early disease â said dr ian m thompson chairman of the department of urology at the university of texas at san antonio and simply because you find it earlier you will always have longer survival after the disease is diagnosed one reason that prostate cancer is diagnosed earlier in the united states than in britain is that they don t screen for it at all in britain at least not at the expense of the nhs which is one of the reasons they spend less on healthcare than the united states they don t indulge in as much screening as we do at any rate his statistics don t appear to be all that far off the mark at least for men in their 80 s but even the nhs admits that prostate cancer survival is increasing because more people are starting to have their psa checked meaning that slow growing early cancers are being added to the mix just as happens here in the us as it happens even back in 2002 the five year survival rate for prostate cancer in the us was 99 still a much better figure than the uk s 71 but as the astute bloggers point out prostate cancer isn t the best example of the benefits of screening prostate cancer is in most cases slow growing and although our screening policies detect many early cancers that would never do harm if left undetected we also end up spending a lot more money treating these same cancers when given the choice between watchful waiting and removal many choose removal another reason why we end up spending more and being less healthy in surveys like this but the astutes take a closer look at cancer in england and cancer in the us see this report entitled cancer survival rates improving across europe but still lagging behind united states and remember that england s rates not broken out are among the worst in europe taking recent figures female five year cancer survival rates are 62 9 per cent on average in the us and 52 7 per cent in england to compare america s privately insured with england s nhs patients you d need to bump up that american survival rate a bit the uninsured most likely have lower survival rates otherwise why worry about universal coverage and bump down the english one because some brits have private insurance and so buy better care nationally american cancer survival rates are significantly better certainly not by the 40 point margin giuliani implied but still looks like the truth is somewhere between rudy and the times posted by sydney on 11 01 2007 09 43 00 pm 5 comments monday october 29 2007 take some tylenol and call me in the morning what will we do without cough and cold medicine i can hear it now that familiar refrain tylenol doesn t do anything and it doesn t at least not for runny noses sneezes and coughs despite what the expert says childrenâ s tylenol and childrenâ s motrin when sold by themselves were excluded from the discussions because the medicines in those products acetaminophen and ibuprofen respectively are safe and effective in treating fevers and aches even in young infants tylenol and motrin are sold in syrupy concoctions that help coughs because the syrup coats the back of the throat and calms cough receptors said dr ian paul a pediatrician at penn state childrenâ s hospital in hershey pa who consults for industry the committee skipped any lengthy discussion of antihistamines like benadryl because there is little debate that such medicines are effective for allergies benadryl also known as diphenhydramine also puts some children to sleep but nearly all the experts said deliberate sedation should be discouraged the medicines that earned the most scorn were those commonly sold to treat coughs runny noses and congestion including dextromethorphan and phenylephrine none of them have any proven effect on childrenâ s cold symptoms all have risks the advisory panel is right however about the effectiveness of the medications they are effective mostly in that they give a parent something to do so they don t feel as if they re standing by while their child suffers the number of children injured by the drugs however has been exceedingly small a study by the centers for disease control and prevention found that at least 1 519 children younger than 2 had serious health problems from 2004 to 2005 after having been treated with common cold medicines three children died the disease control agency found but the argument is that if they don t do any good in the first place then why tolerate any risk but according to this story the pharmaceutical companies say the issue is accidental overdosage not inherent risk in properly dosed drugs the consumer healthcare products association chpa which represents manufacturers and distributors of over the counter medicines said in a statement the data clearly show that these medicines are very safe when used as directed and that harm to this age group while very rare is attributable in most cases to accidental ingestion an issue of safekeeping that is best addressed through education so what to do my recommendation would be not to use them runny noses and coughs aren t in the category of intolerable suffering and these products aren t likely to be much benefit anyway posted by sydney on 10 29 2007 08 10 00 am 3 comments i screen you screen the american academy of pediatrics is recommending that all children be screened for autism they ve only press released their recommendations however so it s difficult to assess them wouldn t it be nice if professional organizations actually released their recommendations to their members before they did so to the public it would make it so much easier for doctors to discuss the news stories with their patients they re releasing them today at their annual conference and later in the november issue of their journal which is not yet available online though it may be in aap member s mailboxes part of any well child visit is screening for developmental delays so one has to wonder what s different about these recommendations are they setting lower limits for what s abnormal so that those mild cases of autism which some argue aren t really autism or even disease can be treated if that s the case then don t be surprised when a couple of years from now there s a upward spike in the number of cases of autism and don t blame it on vaccines posted by sydney on 10 29 2007 07 56 00 am 5 comments sunday october 28 2007 magnet free europe for some reason the eu was proposing severe restrictions on the use of mri scans a proposal which has been halted for now here s the reasoning behind the original restrictions the directive was drafted by dg employment with the aim of minimising workersâ exposure to electromagnetic fields emf currently eight million mri patient examinations per year are carried out in europe said professor dag rune olsen who works in experimental radiation therapy at the norwegian radiation hospital oslo norway and is chairman of the physics committee of the european society for therapeutic radiology and oncology estro â œbut these are likely to have to stop since the directive sets limits to occupational radiation exposure which will mean that anyone working or moving near mri equipment will breach them thus making it possible for them to sue their employers even those maintaining or servicing the equipment may be affected â he said radiation exposure mri s don t emit radiation they detect the magnetic spin of atoms the eu is worried that workers will be
