Skeptips 09.10.02

Homeopater är farliga vaccinationsmotståndare. Det skriver Steven Novella i ett viktigt och läsvärt inlägg på Neurologica-bloggen.

"In a recent press release, the Alliance of Registered Homeopaths simultaneously claim that the H1N1 vaccine is dangerous and not effective, while homeopathic treatments are proven effective. This, of course, is the opposite of the truth. They are essentially saying – don’t use that science-based treatment which doesn’t work, use our absurd snake oil instead."

Richard Dawkins delar med sig av en berättelse om personlig villfarelse. Det handlar om en cykelkorg som kanske eller kanske inte innehåller ett stort lås.

"Be that as it may, I'd have been prepared to go into a court of law and swear that the lock was not there. I would have been thoroughly convincing in the witness box: a jury might have convicted somebody of murder on my evidence. Yet I am now recording here that, as so often with eye-witness testimony, my evidence was worthless."

Ett lavemang var 30:e dag håller tarmen jätteglad! Eller? Nja, men lavemang och tarmrening av diverse slag är trendiga inom den alternativa hälsobranschen. Enligt förespråkarna kan metoderna användas till allt från viktminskning till bättre hälsa.

Dock finns det föga bevis för att det är till någon egentlig nytta förutom vid medicinska behov. Wall Street Journal har en intressant artikel om detta.

""I've seen a lot of colons and the notion that people have pounds of feces and evil toxins built up in there is pure fantasy," says John I. Allen, a Minnesota gastroenterologist who has performed more than 20,000 colonoscopies, including many in patients who haven't drunk the traditional medical cleansing preparation beforehand. Claims for colonics and other forms of cleansing, Dr. Allen says, "just play to people's fears and desire to lose weight.""

Tvärtom kan lavemang göra mer skada än nytta.

"Some gastroenterologists worry that colonics can wash out beneficial bacteria and create infections, abscesses and electrolyte imbalances; there have been cases of rectal perforations."

Hur blir man avgudad av religiösa i Indien? Jo, man kan t ex skära av sig sin tunga och offra den till gudinnan Amba i ett tempel.

"In a bizarre incident, a 35-year-old man, Ramveer Singh Baghel, cut his tongue and offered it to appease goddess Amba at a temple in Meghaninagar on Sunday morning. Devotees, who found him bleeding profusely from his mouth, treated him like a deity and anointed his forehead instead of rushing him to the hospital. Surrounded by devotees, he had not received any medical attention till late evening on Sunday. Baghel too has chosen to stay in the temple. "

Fyndet av ett 4,4 miljoner år gammalt fossil ökar kunskapen om människans ursprung och evolution. Ardi heter den kvinnliga förfadern (förmodern?) och gick enligt forskarna upprätt, men den tolkningen kommer säkert debatteras framöver.

Sussi sa...

ingen aning om lavemang är bra eller inte. Men jag kan tänka mig att man känner sig renare, så placeboverkan kan säkert göra att man får "en nystart" om man t.ex. vill planerar att byta diet.
