VA Physicians Data Apparently Also Lost
-
Printer Friendly|#| Trackback
A laptop containing names, social security numbers, and dates of birth on 26 million veterans was stolen from a VA employee's home on May third. Though extremely concerning, I had no reason to think my data was on that laptop. After all, I'm not a Veteran. A letter arrived yesterday informing me that "[a]s a result of this incident, information identifiable with you was potentially exposed to others." I've worked at the Veterans Administration providing anesthesia care. I can only assume that the laptop contained more than just data on 'veterans and some spouses' but some physicians as well.
I must say I'm surprised by this breach of security. In my experience with the VA, their IT security policies were among the most rigorous and thorough.

Vaccines, Mercury, and Autism--New Data
-
Printer Friendly|#| Trackback
My smart wife tells me that this article is really big news: Early Downward Trends in Neurodevelopmental Disorders Following Removal of Thimerosal-Containing Vaccines (pdf). I've quoted the entire abstract below:
"Contemporaneously with the epidemic rise in neurodevelopmental disorders (NDs), first observed in the United States during the 1990s, the childhood immunization schedule was expanded by the U.S. Centers for Disease Control and Prevention (CDC) to include several additional thimerosal-containing vaccines (TCVs). On July 7, 1999, a joint recommendation was made by the American Academy of Pediatrics (AAP) and the U.S. Public Health Service (PHS) to remove thimerosal from vaccines. A two-phase study was undertaken to evaluate trends in diagnosis of new NDs entered into the Vaccine Adverse Event Reporting System (VAERS) and the California Department of Developmental Services (CDDS) databases on a reporting quarter basis, from 1994 through 2005. Significant increasing trends in newly diagnosed NDs were observed in both databases 1994 through mid-2002. Significant decreasing trends in newly diagnosed NDs were observed in both databases from mid-2002 through 2005. The results indicate that the trends in newly diagnosed NDs correspond directly to the expansion and subsequent contraction of the cumulative mercury dose to which children were exposed from TCVs through the U.S. immunization schedule."
The big news is the last sentence: trends in newly diagnosed ND's [ed: autistic spectrum disorders] correspond directly to the expansion and subsequent contraction of the cumulative mercury dose to which children were exposed from TCVs through the U.S. immunization schedule.
There were suspicions during the time that vaccines contained Thimerisol that it was responsible for an associated increase is the so-called autistic spectrum disorders. The suspicion was based on reports of increases in autism in the community. These were explained away by the observation that diagnosis had become much better during the same time period and the fact that scientific data supporting such a link were of very poor quality. Nonetheless, many parents chose to forgo immunization of their children out of concern that vaccination would increase their risk of autism or related disorders. Skipping immunization did not increase their risk of infectious disease because of herd immunity, up until enough members of a population are unprotected and disease can once again propagate among the non-immunized.
There are ongoing flame wars among blogs about this issue, but his article should cause many of those involved to rethink their position.

Desperate for Dollars - The Nation of Guinea Pigs:
"How India became the global hot spot for drug trials. Big pharmas have a billion people vying to be part of clinical trials of untested drugs. Areas known only for snakes and heat now have good hospitals after the government passed a law allowing the drug testing and advertised its "treatment naive" patients."

Aspect Medical Fearmongering Pays Off
-
Printer Friendly|#| Trackback
Aspect Medical is the company that sells the 'awareness' monitors for anesthesia. Their product is the one featured so prominently in photos accompanying every print story I've seen on intra-operative awareness. This Yahoo Finance headlines seems to indicate it's paying off:
"Aspect Medical posts revenue, profit gains in 2005 (bizjournals.com via Yahoo! Finance):
Aspect Medical Systems Inc. ended 2005 with a large jump in both revenue and net income, as demand for its anesthesia monitoring systems expanded at a healthy clip."
Full disclosure: I still don't use a BIS monitor

Are Lower Back Tattoos A Contraindication To Labor Epidurals?
-
Printer Friendly|#| Trackback
My Google News section on 'epidurals' came up with an interesting hit: Lower-back tattoos are popular with women, but do they make having epidurals during childbirth more dangerous?. It's a very good question because, at least in my practice, lower back tattoos are extremely common in laboring women. So common, in fact, that Saturday Night Live has a commercial parody for a product called Turlington's Lower Back Tattoo Remover (quicktime | windows media).
I was taught to avoid putting an epidural needle through tattooed skin and have gone to great lengths to do so. For example, one patient had a very large tattoo of what appeared to be the face of the devil on her lower back. On closer inspection, I noticed that the devil's right nares (which was free of tattoo ink) was right over her L3-4 interspace. I wished I'd taken a picture of that epidural catheter snaking out of the devil's nose.
I can't seem to find much science on the subject save for one abstract which makes a very reasonable suggestion to avoid coring out tattooed skin by making a small incision, if necessary. This may sound like a lot of trouble, but all it takes is a 16 gauge (or similarly large) hypodermic needle inserted into the skin first, then the epidural needle through that 'incision'.

No Trasylol For Me or My Patients, Please
-
Printer Friendly|#| Trackback
Trasylol (Aprotinin) is a very expensive drug used during many kinds of cardiac surgery to reduce blood loss. In today's print edition of the NEJM (but not online yet) is a very important article by Dennis Mangano (very, very smart anesthesiologist) which shows an "association between aprotinin and serious end-organ damage" including doubling the risk of renal failure requiring dialysis, a 55% increase in the risk of MI or heart failure, and a near doubling of the risk of stroke or encephalopathy. The good news is that there are alternative drugs which cost one tenth as much and are also very good at reducing the need for blood transfusion. More soon....

Prilosec and C.Diff?
-
Printer Friendly|#| Trackback
Reading a blog far afield of medicine, then to the Washington Post, I cam across an interesting nugget on C. Diff. The JAMA published an article on December 21, 2005 titled Use of Gastric AcidâSuppressive Agents and the Risk of Community-Acquired Clostridium difficileâAssociated Disease [abstract]. In two population-based case-control studies:
" The incidence of C difficile in patients diagnosed by their general practitioners in the General Practice Research Database increased from less than 1 case per 100 000 in 1994 to 22 per 100 000 in 2004. The adjusted rate ratio of C difficileâassociated disease with current use of proton pump inhibitors was 2.9 (95% confidence interval [CI], 2.4-3.4) and with H2-receptor antagonists the rate ratio was 2.0 (95% CI, 1.6-2.7). An elevated rate was also found with the use of nonsteroidal anti-inflammatory drugs (rate ratio, 1.3; 95% CI, 1.2-1.5). "
A teleconference is planned for January 18th to discuss these results as part of the new Author-in-the-room series.
