prevalence
The e-medicine article suggest 0.01% (1 in 10,000) of population is afflicted with Situs inversus, we appear to use this statistic. http://healthlink.mcw.edu/article/901226430.html suggests 1 in 7000 to 8000 is afflicted. Which shall we use? --OldakQuill 19:57, 6 May 2004 (UTC)
- 0.01% might be a rounded figure. Fredrik 20:19, 6 May 2004 (UTC)
- This page (http://www.ehendrick.org/healthy/002176.htm) gives 1:8500. Ksheka 13:02, May 8, 2004 (UTC)
- This page (http://www.medigraphic.com/ingles/i-htms/i-circir/i-cc2000/i-cc00-2/ir-cc002f.htm) suggests 2 out of 118,012 patients, whereas this one (http://www.sma.org.sg/smj/4007/articles/4007me3ans.html) suggests 1 in 8,000. Well, it's rare, just exactly how rare I'm not sure ... Alex.tan 18:37, 9 May 2004 (UTC)
background
The developmental biology of Situs inversus must be governed by the action potential which orders the formation of the tissues of the inverted organs. Ancheta Wis 03:10, 7 May 2004 (UTC)
In particular, the heart is really a spiral of muscle (see Hermann Weyl's book on Symmetry; thus the heart in Situs inversus may be also a inverted spiral as well) Ancheta Wis 03:10, 7 May 2004 (UTC)
When a genetic marker for this condition is discovered, it ought to be possible to detect a difference in action potential during the transition from morula to blastula, as compared to the usual development stages.Ancheta Wis 10:25, 7 May 2004 (UTC)
I've got a book at home with loads on the history of how situs invertus was first discovered. If I get time over the weekend (which actually is probably unlikely) I'll add it in. Otherwise, if anyone wants to look it up and do it themselves, the book is Left Hand, Right Hand (and there's plenty of info at the book's website (http://www.righthandlefthand.com)). --ALargeElk 13:36, 7 May 2004 (UTC)
images
Does anyone know of any free images of this? I suppose mirroring regular x-rays won't do. Fredrik 09:47, 10 May 2004 (UTC)
- why not ;-) e 02:05, 11 May 2004 (UTC)
- Mirror this? (and remove labels)Bensaccount 04:18, 13 May 2004 (UTC)
- urg... a good start, but I'm not personally a fan of those old gray's images - all that texture hides the point... anybody got anything clearer? don't forget it affects the abdomen as well. --e 14:20, 13 May 2004 (UTC)

anatomy
I do not at all understand the meaning of this: Individuals with situs inversus that require transplantation of solid organs (e.g., the liver) may have issues regarding managing the altered anatomy they present with. "Regarding managing" and "present with" aren't even proper English, I think, but I don't understand this well enough to clarify it. Also, I think it'd be nice to know something more about these issues. Nickptar 00:29, 11 May 2004 (UTC)
- this is just a 'left' shoe on 'right' foot problem - could be said clearer tho. e 02:05, 11 May 2004 (UTC)
