[edit] Pictures?

Pictures of people infected with the disease would be a nice addition. Maybe just their hands. Randomfrenchie 01:10, 9 February 2007 (UTC)

[edit] groundwater nitrate

"It can be caused by drinking water nitrate-nitrogen levels that exceed current EPA standards of 10ppm. Nitrate can cause the reaction in the bloodstream, especially in babies."

Actually Methemoglobinemia is caused by drinking water with elevated nitrite-nitrogen levels. Levels of nitrite associated with the reaction have not been documented - levels are transitory. The EPA nitrate criteria is a proxy for dealing with the nitrite concern. Nursing babies are particularly sensitive because their ability to metabolise nitrite is undeveloped. Young children are capable of digesting large quantities of nitrites. The sales of lunch meat and hot dogs relies heavily on this metabolic capacity.- Paleorthid 17:52, 24 January 2006 (UTC)

Changed. -- Irixman (t) (m) 23:36, 4 June 2006 (UTC)
I have found a more informative reference that indicates my previous understanding, as stated above, was simpplistic. Nitrates in water are a problem (in addition to the nitrites) for infants because they metabolize nitrates into nitrites. -- 67.185.75.97 01:24, 5 June 2006 (UTC)


The Fugates of Kentucky/West Virginia do not have methemoglobinemia from drinking water, it is a recessive gene carried down in the family. Both parents must carry this gene in order to produce a "blue" child. I know this because I have Fugates in my family lineage and have done research on this family line. There are at least eight generations in my family between the Fugate line and the Ritchie line that have "blue" skin and fingernails. ~~FloraCalifornia

[edit] Appalachian Blue People (merger debate)

Suggested addition: A very well-known series of cases was among the Moon Family of Eastern Kentucky/Western Virginia area. It carried on through several generations, due to a high amount of intermarriage in the area. This might be an informative addition to the article

Added, but I saw it was among the Fugate family, per my cited reference. -- Irixman (t) (m) 23:36, 4 June 2006 (UTC)


I disagree. Do not merge this entry with the entry on the Blue Fugates of Appalachia - continue to provide links and cross-references between the two articles. The Blue Fugate entry has the potential to be expanded as a family history, with many details outside the scope of a general overview of methemoglobinemia. See FloraCalifornia's note above for an example. If more information about the Fugate family is posted to Wikipedia, it would simply clutter up a combined entry, and result in the entries being split apart anyway. -- 71.162.11.76 04:30, 23 November 2006 (UTC)
I googled 'Blue Fugates' hoping *specifically* to find a Wikipedia entry on them. Since I wrote the above^^^ comment, you have removed all but the most basic information about the Blue Fugates - now there is NO room for the type of biographical information I was looking for, and the Fugates are reduced to a one-paragraph example of symptoms. Can you please explain this decision? -- 71.162.11.76 19:37, 25 November 2006 (UTC)
I reverted Blue Fugates back to its state before redirect. I couldn't find any record of this merger reaching consensus--the only comments on it seem to be the ones above, which go against it. (I'd second that vote). Torc2 23:09, 5 October 2007 (UTC)
I am for a merge because the Methemoglobinemia article has all of the information that this article has. As for the argument that the addition of more information about the blue fugates would clutter the methemoglobinemia article... no content additions have been made to the blue fugates article since its december 2005 creation... almost two years ago. I seriously doubt a content addition is coming. Also, a number of merger attempts have been made and reverted (including my own), demonstrating that support exists for a merger even if not in the form of 'offical' votes on the discussion page. --Nanobri 01:53, 8 October 2007 (UTC)

Let's please close the debate on this page and discuss it from scratch over here (as is normal procedure according to Wikipedia:Merging_and_moving_pages#Proposing_a_merger. Torc2 04:37, 14 October 2007 (UTC)


[edit] Symptoms

I am unsure exactly what the percentages indicates. 70% of people exposed to the LD-50 of any nitrite die? It takes 70% over a normal dose to kill someone? Etc... please readd if anyone knows what they truly indicate, and explain a ibit. -- Irixman (t) (m) 23:36, 4 June 2006 (UTC)

[edit] Removal of probable copyvio material

This series edits by an anon IP editor on 21 August would seem to be a copyvio, given the use from nowhere of numbered footnotes (the article does not use the cite.php system, and certainly not from number 24). As such I have removed the material on sight, (as shown below):

It has been reported (Heard & Ashworth 1968 apud Basrani et al. 2007) that, when placed in an aqueous solution, Chlorhexidine Gluconate (antiseptic) slowly hydrolyzes and forms para-chloroaniline (4-Chloroaniline, p-Chloroaniline or PCA) (24). Para-chloroaniline (PCA) has been shown to be toxic (28, 29). As an aromatic amine, the primary toxic effect is methemogloblin formation (28). Toxicological studies in rats and mice have shown that the hemopoietc system is the major target for PCA (28). In 1990, Chhabra et al (28) conducted a 90-day study (with p-chloroaniline) and found that methaemoglobin formation and accompanying haemolytic anaemia, extra-medullary haematopoiesis, and splenomegaly were indicative of erythrocyte toxicity and regenerative anemia.

Could editors with knowledge of the topic consider if the points that the paragraph covers are notable, and if so include in a fresh manner. David Ruben Talk 01:27, 23 December 2007 (UTC)

[edit] Help citing source on vitamin C

So, I thought the statement at the end of the Treatment section that said "Also vitamin C cures this condition" seemed kind of dubious. I found vitamine C talked about at http://www.emedicine.com/MED/topic1466.htm and replaced the statement with what it says there. I don't know how to properly reference the website though. Can someone help me? Nanobri (talk) 00:08, 23 February 2008 (UTC)

[edit] Acute Acquired Methemoglobinemia

I recently was diagonosed with this after going to the doctor for what was pneumonia. The doctor mentioned I looked blue...and after many expensive tests (no medical insurance) they did an areterial blood gas test and found my oxygen level was 97% even though the finger test showed it between 84-89. The culpit was Dapsone, used to treat the skin disorder associated with Celia Sprue. Before they reversed it, my hands were a dark gray blue...people were telling me I looked dead. I was fortunate that it turned out to be something that is reversible. I hope never to feel that bad again. Admiralcaptain (talk) 19:23, 13 May 2008 (UTC)
