Aah, the French:
The idea of putting maggots into open flesh may sound repulsive, but such a therapy might be a quick way to clean wounds, a new study from France suggests.
via Maggots Clean Wounds Faster Than Surgeons | Wound Healing | LiveScience.
I kid. I think this is a good idea, and it’s natures’ way of saying ‘cleanup on aisle three’. Patients not infrequently will be brought to the ED with awful, non-healing wounds infested with maggots.
We typically kill them off, more because a) the staff is completely grossed out and b) if you’re living at home and have maggots in your wounds, let’s just say your personal hygiene is deeply suspect. Rank, in fact. Needs a decon level bad.
However, there is a legitimate role for biological wound cleaning; I have a WWII surgical book with a chapter in it on growing your own sterile maggots. It’s not an ER thing, but it’s yet another tool in the armamentarium of bad wounds.

The popular proverbial saying “you cannot have your cake and eat it too” implies that one cannot consume something and preserve it at the same time–in other words, we cannot have it both ways. Well, for once, maybe we can have our cake–our whole genome sequence (WGS)–and eat it too. I believe having our WGS and consuming it in small bite sizes over a lifetime may be the only way to integrate it into medicine and public health.
Rapid advances in genomic sequencing technologies are making the possibility of reliable and affordable whole genome sequencing (WGS) a reality in the next few years. We all carry about 6 billion base pairs of DNA in each of our cells, with 5-10 million inherited variants that are different among us. This genetic variation along with environmental influences provides a blueprint for health throughout the life span, and is related to virtually every disease of public health significance. There is definite interest among the public and scientists about the personal utility of this information. In a recent survey by Nature, attitudes towards genome sequencing were explored among a sample dominated by scientists and professionals from medicine and public health. Although only 18.2% of respondents had had their genome sequenced or analyzed, 2/3 of those who had not reported they would take the opportunity should it arise. Curiosity was reported as the main single factor influencing respondents.
Can this information be useful today in improving medical care and preventing disease? Read more »

From The Australian:
Stem cell researchers have found a way to turn a person’s skin into blood, a process that could be used to treat cancer and other ailments, according to a Canadian study published today.
The method uses cells from a patch of a person’s skin and transforms it into blood that is a genetic match, without using human embryonic stem cells, said the study in the journal Nature.
Wow. Very cool. I wonder if hopefully someday this could be a replacement for random blood donation?

Continuing this week’s spontaneous theme (we didn’t make the claims and write the stories) of runaway enthusiasm for various screening tests by some researchers and journalists, HealthDay news service has reported on a study published in the Oct. 28 issue of the journal Nature that they say “provides new insight into the genetics of pancreatic cancer.” In the story, they let one of the researchers get away with saying, almost unchallenged:
“What’s important about this study is that it’s objective data in support of why everyone should be screened for pancreatic cancer.”
Mind you, this was a study that looked at tissue from just seven patients. The story continued with its breathless enthusiasm for the pancreatic cancer screening idea:
“In the future, new imaging techniques and blood tests will offer hope for early detection, the study noted. And just as people have a colonoscopy when they turn 50, “perhaps they should have an endoscopy of their upper gastrointestinal organs that includes an ultrasound of the pancreas,” said (the researcher).”
The very end of the story included some skepticism from Dr. Len Lichtenfeld of the American Cancer Society. Read more »
