No, it’s not one of those “name three things that don’t go together” deals, it’s a strange but true story that started with a German patient with strange symptoms that no one could figure out. But a doctor at the Centre for Undiagnosed Diseases in Marburg, Dr. Juergen Schaefer, a ‘House’ fan, recognized the symptoms from an episode featuring a patient with a deteriorating artificial joint and was able to determine he was suffering from cobalt poisoning as a result of an old pair of hip replacements. Once the metal joints were replaced with ceramic he made a partial recovery (some of the damage was permanent).
But, you ask, what about the beer? It turns out that cobalt poisoning is extremely rare, mostly confined to steelworkers (cobalt is used as an additive). But there was also another group that was affected, beer drinkers in 1960s Quebec. That’s because a brewery, Dow, added cobalt sulfate to its beer to help foam stability. Although most drinkers had no problems with the beer, very heavy drinkers ingested enough cobalt to come down with symptoms. Dow went out of business in 1997, sales never having recovered from the incident.
Om Malik, himself a diabetic, looks at Google’s Smart Contact Lenses.
While I was aware that diabetics must be aware of a number of health issues (in addition to their blood sugar levels) the recommendation against contact lenses is new to me. Diabetic health is definitely an area that could use some automation, obviously, but smart contacts aren’t the answer.
After bailing out of the approval process, 23andMe’s DNA testing kit was (technically) banned from sale by the FDA. But it’s still for sale.
Charles Seife in Scientific American says that’s not the reason you should be concerned. That’s because 23andMe’s real business isn’t medical research, it’s data collection.
I’ve blogged this before but since it’s coming onto swimming season, it bears mentioning again: Drowning doesn’t look like drowning. It’s nothing like you’ve seen in movies and TV so educate yourself and you just might save a life.
Craig Bowron asks this important question: Is testosterone testing important? And is treating a condition that is not well understood with a hormone who’s effects are not well understood a good idea?
Or as I like to put it: Getting older is NOT a disease!
If you think contaminated ground water, increased seismic activity and unknown impacts to the food chain are a bad idea, there’s still time to comment on NY’s regulations on hydraulic fracturing (fracking).
