Negative pressure wound therapy

A streamlined version of ‘negative-pressure’ wound therapy is put to the test in Haiti — and could have ‘enormous potential’ across the developing world.

Nobody knows precisely why it works, but doctors have known for decades that the healing process for open wounds can be greatly speeded up by applying negative pressure — that is, suction — under a bandage sealed tightly over the affected area. The speculation is that it helps by drawing bacteria and fluid away from the wound, keeping it cleaner.

For patients, there is a benefit even beyond the speedier healing. Traditional dressings need to be removed and replaced — sometimes painfully — up to three times a day, but with the negative pressure system dressings can be left in place for a few days. But in the developing world, there’s a problem: The systems are expensive, and they need to be plugged in or powered by batteries that last only a few hours. In many developing nations, a reliable source of electricity is rarely available.

Mmmm… Freshly ground black people

An Australian publisher has had to trash and reprint a cook-book after one recipe listed “salt and freshly ground black people” instead of black pepper.

PastaPenguin Group Australia had to reprint 7,000 copies of Pasta Bible last week, the Sydney Morning Herald has reported.

The reprint cost A$20,000 ($18,000; £12,000), but stock in bookshops will not be recalled as it is “extremely hard” to do so, Penguin said.

The recipe was for spelt tagliatelle with sardines and prosciutto.

“We’re mortified that this has become an issue of any kind, and why anyone would be offended, we don’t know,” head of publishing Bob Sessions is quoted as saying by the Sydney newspaper.

Penguin said almost every one of the more than 150 recipes in the book listed salt and freshly ground black pepper, but a misprint occurred on just one page.

“When it comes to the proofreader, of course they should have picked it up, but proofreading a cook-book is an extremely difficult task. I find that quite forgivable,” Mr Sessions said.

If anyone complains about the “silly mistake”, they will be given the new version, Penguin said.
