5:51 AM | Mike Adams and NY Post promote more hysteria over Ebola
I’ve been asked several times about this NY Post article on the CDC’s “admission” that a sneeze could spread Ebola. The Post (which, I should note, is the least credible newspaper in New York City, for those not familiar with the paper) suggests that the CDC has changed their tune regarding the spread of Ebola.…

9:04 PM | The Return Of The CDC’s `How Ebola Spreads’ Infographic
Droplet Spread – Credit CDC   # 9273   Earlier today I mentioned that an infographic showing that Ebola can potentially spread over short distances via droplets had been temporarily pulled by the CDC, just 5 days after first releasing it (see Guidance Gone, But Not Forgotten).   Since this removal was causing such a stir online and in the media, I expressed hopes it would be reinstated soon.   Well, I very pleased to say that a slightly modified […]

6:38 PM | WHO Ebola Response Situation Report – Oct 31st
# 9263   The numbers coming out of West Africa continue to bounce around, with the total number of cases actually down by nearly 200 over the report from October 29th, but the number of fatalities slightly higher. This drop in cases was attributed to some suspected cases in Guinea being ruled out.   Given the limits of surveillance and reporting in these three countries, there’s not a great deal of faith that the numbers we are getting truly represent the […]

12:55 PM | SEVERE CHRONIC HYPONATREMIA: A Pathophysiological Rumination.
PART 4: CONTROL ISSUES1. Losing Control:In the preceding posts, I explained how sudden emergence of water diuresis as the predominant mechanism by which rapid overcorrection of serum sodium happens in cases of severe chronic hyponatremia.  Few situations or more stressful in nephrology than when we suddenly find that serum sodium has increased by 12 mmol or more within a few hours. The usual scurried response is the immediate administration of 5% dextrose water, DDAVP are both.

12:32 PM | Brain Size and Intelligence
I was recently asked about the relationship between brain size and intelligence. This is a question I get every now and then, because the relationship is not an obvious one. In this particular case, the questioner was curious about the fact that Neanderthals had a larger cranial capacity on average than modern Homo sapiens. For [...]

12:27 PM | Guidance Gone, But Not Forgotten
  # 9269     Generally speaking, I’m very supportive of the CDC in this blog. Like most Americans, I recognize that they have a tough job to do, and have consistently viewed them more favorably than any other Federal agency.   While I’ve occasionally been critical of their messaging, I’ve always tried to convey my concerns with respect – not scorn.   Last Saturday, when the CDC released the following infographic (see CDC: […]

10:00 AM | Antivaccinationists versus Jonas Salk’s centennial
One thing that happened this week that I didn’t get around to writing about is the 100th anniversary of the birth of Jonas Salk, which was October 28.

9:16 PM | CDC Guidance: Considerations For Discharging Persons Under Investigation For Ebola
CDC Infographic: Is it flu, or Ebola?   # 9268   As has already been demonstrated, while a fair number of people may be initially suspected of having Ebola, few will actually end up being infected with the virus. The CDC has fielded calls on scores of `suspected’ Ebola cases from hospitals around the country – performed testing on dozens – and yet only small handful have tested positive for the virus.    Today the CDC has issued guidance on […]

Since Ebola is only spread very late in the disease, like when you are sick and in the ICU, it goes without saying that Kaci Hickox is no risk to her community. But she looks to be in great shape, so any squirrel in the road better watch out!

3:20 PM | Alcoholism as a Reward System Dysfunction
Alcoholism and other addictive behaviors often occur together within individual patients.For example, individuals with alcoholism commonly also are smokers and meet criteria for a diagnosis of nicotine dependence.This co-occurrence suggests multiple types of addiction may share genetic and environmental risk factors.

2:42 PM | All The Ebola News Not Fit To Print
      # 9266   Earlier this week a `fake’ news story made the rounds of Twitter and Facebook, suggesting that students at an Elementary school in Olanthe, Kansas had been infected with the Ebola virus.   When I was first alerted to the story, I did a quick search, found the offending article, and quickly determined it was fake.   Unfortunately, the story did what it was intended to to – it went `viral’ – and […]
