C diff Guidelines: Metronidazole Still Preferred?

IDSA and The Society for Healthcare Epidemiology of America (SHEA) have published Clinical Practice Guidelines for Clostridium difficile infection. Not surprisingly, it’s a comprehensive, extensively-referenced document that will be an invaluable resource, especially since the previous version is approximately 15 years old. But with the caveat that I’m not an expert in this area, these particular treatment recommendations […]

Now for Some Good News: TB Cases Continue to Decline

From the latest MMWR: This figure speaks for itself, but two sentences from the Editorial Note deserve highlighting: The 11.4% decrease in reported TB rate in 2009 is the largest single-year decrease ever recorded. From 1953 to 1993, the single largest annual percentage decrease in TB case rate was 11.1% in 1956 Since I started my ID career […]

Bats in the Bedroom: Canadians Make a Policy Change

ID doctors know all too well the panicky call — usually from a terrified friend, family member, or colleague, or possibly the emergency room or primary care doc — about finding a bat in the house. Usually in the bedroom. (In one memorable case, it was the house cat’s leaping in the air to try and catch […]

Magic Wand Destroys H1N1 — and More!

From the folks at Hammacher Schlemmer comes this extraordinary device: Tests performed by an independent antimicrobial testing laboratory showed the wand destroyed 99.98% of the H1N1 virus after a five-second exposure when held 3/4″ above the contaminated surface. Also capable of killing MRSA, mold, and dust mites, the UV-C light penetrates viral and bacterial membranes and […]

Holiday Surprise: Generic Valacyclovir

Last week one of my patients went to refill a Valtrex prescription, and was offered generic valacyclovir for the first time.  It made him nervous, so he requested I write a “brand-name only” script. I confess the existence of a generic formulation of valacyclovir — which according to the PharmD here has been available for several […]

So Much in Less than a Week!

First the updated WHO Guidelines.  Then the following: Updated DHHS Guidelines.  Agree?  Disagree?  Sensible or crazy?  Practical or ivory-tower academic? South Africa does the right thing.  Yes, it’s about time, but good news nonetheless. 2012 International AIDS Meeting in Washington, D.C. First time in USA in a long, long time — 1990, to be exact — […]

WHO HIV Treatment Guidelines Updated

This just in: WHO is now recommending that ART be initiated at a higher CD4 threshold of 350 cells/mm3 for all HIV-positive patients, including pregnant women, regardless of symptoms. Which makes eminent sense, of course.  Because if starting HIV therapy might prolong survival in developed countries, why shouldn’t it do the same in the developing world? In fact, […]

Ties Tied to Bugs

Are doctors’ neckties causing infections?  That’s the implication of this Wall Street Journal piece: The list of things to avoid during flu season includes crowded buses, hospitals and handshakes. Consider adding this: your doctor’s necktie. … A 2004 analysis of neckties worn by 42 doctors and medical staffers at the New York Hospital Medical Center of […]

Would Changing Restrictive HIV Testing Laws Improve Survival?

Emphatically yes — to the tune of >600,000* years of life gained nationwide.  So says a nifty paper being presented at the annual IDSA meeting today by Mike April, under the direction of Rochelle Walensky. (*Original abstract said 549,437, cited in the link; number at the actual presentation, though, was 609,656.) Bottom line is that laws that […]

Well That Was Fast! HIV Vaccine Trial Published

Remember the HIV vaccine trial press release?  The one announcing the first-ever positive result? Then the backlash, with people questioning how the analyses were done, and reported? Now, less than a month later, we have the scientific presentation and the paper appear on the same day. Read all about it here and here. If you want the view […]
