[2010] Do pregnant women need to abstain completely from drinking? - By Libby Copeland - Slate Magazine

http://www.slate.com/articles/double_x/doublex/2010/10/drinking_while_pregnant.html This is why an obstetrician will warn patients not to consume any alcohol whatsoever, but tell a particular panicked woman who reports drinking twice before she realized she was pregnant that her baby is fine. "I will strongly suggest to women who plan pregnancy that they don't drink," says Gideon Koren, who directs a clinical, research and teaching program called Motherisk at the Hospital for Sick Children in Toronto. After all, Koren says, lack of proof of harm does not equal lack of harm. And alcohol is not like asthma medication, worth some risks because of benefits to the mother's health. But that doesn't mean he expects the babies of women who drink a bit to be harmed by it.

Auto-appendectomy in the Antarctic: case report -- Rogozov and B

The Russian surgeon Leonid Rogozov’s self operation, undertaken without any other medical professional around, was a testament to determination and the will to life The ship Ob , with the sixth Soviet Antarctic expedition on board, sailed from Leningrad on 5 November 1960. After 36 days at sea she decanted part of the expedition onto the ice shelf on the Princess Astrid Coast. Their task was to build a new Antarctic polar base inland at Schirmacher Oasis and overwinter there. After nine weeks, on 18 February 1961, the new base, called Novolazarevskaya, was opened. http://www.bmj.com/content/339/bmj.b4965.full

APL scientists and engineers developed the underlying technology under DARPA's Revolutionizing Prosthetics 2009 program, an ambitious four-year effort to create a prosthetic arm that would by far eclipse the World War II era hook-and-cable device used by most amputees.

Pourquoi, pour dormir la nuit, doit-on se couvrir sans quoi nous avons froid? Ce phénomène s'explique par la baisse de la température du corps dans la phase du sommeil. http://ptaff.ca/blogue/2010/08/07/pourquoi_doit-on_se_couvrir_lorsque_lon_dort/

Pourquoi doit-on se couvrir lorsque l’on dort?

The kind of drowning you see on T.V.—think thrashy, screamy—doesn't have much in common with what real drowning looks like, according to writer and Navy/Coast Guard veteran Mario Vittone . That's because of something called the Instinctive Drowning Response, a pattern of behavior that appears to be hard-wired into humans and pops up whenever somebody feels like they're suffocating in water. Frank Pia, Ph.D. , the psychologist and lifeguard to first described the Instinctive Drowning Response explains it this way :

Effect of traditional chinese medicine on survival... [Chin J Integr Med. 2006] - PubMed result

http://www.ncbi.nlm.nih.gov/pubmed/17005076 To explore the effect and possible mechanism of traditional Chinese medicine (TCM) on survival and quality of life (QOL) in patients with esophageal carcinoma after esophagectomy. Adopting prospective controlled method of study, the authors had 128 post-esophagectomy patients, hospitalized from February 2001 to February 2002, randomly divided into 3 groups: the TCM group, treated with TCM drugs alone; the chemotherapy group, with chemotherapy alone applied; and the synthetic group, treated with chemotherapy combined with Chinese medicine. Their survival rate and QOL were compared.
Souvent parée de toutes les vertus, l’ADN n’est pas la “ reine des preuves ” : erreurs de manipulation, d’analyse ou de conservation, “ faux positifs “… les annales policières et judiciaires ont d’ors et déjà répertorié plusieurs cas de personnes, accusées et incarcérées, à tort, parce que leur ADN les désignait comme suspectes (voir Quand les “experts” se trompent ). Plusieurs scientifiques tirent aujourd’hui la sonnette d’alarme : les taux d’erreurs seraient bien trop importants. En juin 2010, plusieurs utilisateurs de 23andme, l’une des entreprises proposant de décoder son propre ADN (voir L’avènement de la génomique personnelle ), découvrirent , stupéfaits, qu’ils n’avaient pas le même ADN que leurs enfants, frères, soeurs, parents, ou bien qu’ils étaient noirs, ou asiatiques (alors qu’ils étaient blancs)…

New guide aims to bring sense to the media coverage of drugs | Media | guardian.co.uk

A guide to help prevent the myth-representation of drugs I was expecting to speak at midday today at the launch of an excellent pamphlet The media guide to drugs: Key facts and figures for journalists produced by an organisation called DrugScope . It is a superb, comprehensive piece of work, running to 140 pages, that should prove invaluable to all journalists who write at any time about drugs . Sadly, there are no trains this morning from Brighton to London because of the snow, so I will not be able to attend the launch after all. If I had done so, I would have said that newspapers have had a poor record in reporting on drugs. They have contributed to the widespread misunderstanding about the topic.

Where do most people get their information about drugs? From the press. And where does the press get its information?

[2010] Variole, le retour | Courrier international

Trente ans après son éradication, le virus de la variole frappe à nouveau en République démocratique du Congo (RDC). Selon une étude de l'Université de Californie à Los Angeles réalisée entre 2005 et 2007 et relayée par la revue espagnole Publico , il s'agirait d'une variante animale transmissible à l'Homme. 760 nouveaux cas ont été détectés dans différentes régions du pays mais le taux de mortalité de cette épidémie reste à déterminer. Il n'existe aucun traitement contre la maladie.
La viruela, erradicada en 1977, ha regresado a África en una forma menos peligrosa, pero rodeada de misterio. Se trata de la viruela del simio, una variante animal que está saltando a personas, según un estudio realizado en la República Democrática del Congo (RDC) entre 2005 y 2007. El trabajo señala que, desde que se puso fin a la campaña de vacunación en este país en 1980, los casos de viruela del simio se han multiplicado por 20.
