[edit] Types
The layout of this section confuses two orthogonal issues. Urticaria can be acute or chronic. By the definition I'm working from, an acute case is one with a duration less than 6 weeks, and a chronic case is longer than that. Separate from duration, the symptoms can be differentiated based on cause (e.g. physical, contact, infections, etc.). --Ipsuid 01:10, 11 February 2006 (UTC)
I'm curious about streptococcus induced urticaria. Is there a reference anywhere for that? Claire --ClaireMullan (talk) 08:32, 15 March 2008 (UTC)
[edit] Treatments
"The most recently proposed allergen is long-term accumulation of laundry detergent residues in the skin." This sounds kind of quack-ish... is there any evidence of it?
- I spent a few minutes researching in medical journals, and couldn't come up with any studies showing this. I might not have looked hard enough. There is a class of Urticaria that is caused by contact with substances (Contact Urticaria), so it is conceivable that a procedure like this may provide relief for some. But I think that this paragraph may need to be reworked a bit. --Ipsuid 01:10, 11 February 2006 (UTC)
I was prescribed prednisone for chronic hives and angioedema by an allergist (after Zyrtec, Tagamet, Allegra, etc. had no effect), and it was the only treatment that seemed to work. Should prednisone / corticosteroids in general be added to the treatment section? I have no formal sources or citations, I'm afraid... --Dirk Gently 16:13, 6 April 2006 (UTC)
- Well, I put it there now. Hopefully someone has some sources for all this stuff. (And just for the record, the laundry detergent bit does sound quack-ish.) --Dirk Gently 15:40, 12 May 2006 (UTC)
I don't think the laundry detergent thing is quackish. I recently broke out into hives and was prescribed several different drug treatments that didn't work. The last prescription I had recieved was for prednisone, which worked but I didn't want to use it for long term treatment due to it's nasty side effects. After visiting an allergist for tests I found out my allergic reaction and hives were being caused by the laundry detergent I was using (they recently changed there formula). After discontinuing use of that laundry detergent and switching to one that is dye and perfume free my hives and all alergic reactions have been gone for months now without the use of any meds. So to me it doesn't sound quackish since I've been medically diagnosed as having a severe allergic reaction to certain dyes, perfumes, and chemicals that are commonly used in laundry detergent. I recently also read a story about a young girl that died in england from a severe allergic reaction to a toothpaste she used. The toothpaste's formula had recently changed and after a few weeks of getting hives and progressively worse allergic reactions she went into anaphylactic shock and died. They later figured out her allergy was do to the reformulated toothpaste. 208.50.36.230 (talk) 20:21, 23 January 2008 (UTC)
[edit] Picture
How about getting a picture that complies with the description? I don't see any red in the current one. Twilight Realm 01:29, 22 March 2006 (UTC)
- Hmm... do you think this picture (http://www.ceruleantown.com/albums/album32/DSCN1287.jpg) is any better? It is a pic I took, I could upload it here... Emmyceru 14:45, 10 August 2006 (UTC)
- Oh, and forgot to mention, that was induced by an antibiotic, similar to the picture that is already in the article. Emmyceru 14:48, 10 August 2006 (UTC)
[edit] Sources
There is a lot of medical information and claims about treatment that should be cited. - Victah 10:27, 5 April 2006 (UTC)
I agree, these treatments should be cited or removed. The one cited above as 'quackish' has some real red flag pseudo-technical language.
[edit] Pronunciation
How is "urticaria" pronounced?
- Assuming my doctor had it right (and that I can remember it from about a decade back), "er-ti-CARE-ear". First syllable as in the word "earth". Second as in "tick", third as in the verb to care, fourth as in the things on the side of your head you hear with. BigHaz 03:45, 13 July 2006 (UTC)
- I've always heard it to be pretty much the same, but ending in a two-syllable "ia", like it's spelled. Could be regional, though. --Dirk Gently 20:15, 10 August 2006 (UTC)
ia is not pronounced 'ear', ever. —Preceding unsigned comment added by 155.188.183.6 (talk) 20:12, 26 December 2007 (UTC)
[edit] add this somewhere somehow
Found this chunk in another atricle (Contact dermatitis):
"Contact urticaria is another form of allergic reaction. Its mechanism is classified as Type I allergy, and is different in nature to ACD in the toxins responsible, the toxicolgical mechanism and, more importantly, the time scale overwhich the reaction occurs. As mentioned previously, ACD requires both sensitisation and elicitation, whereas Type I reactions only require a single exposure to the allergen. Contact urticaria manifests itself as small itching wheals (ESCD 2006) which disappear soon after appearing. It has been shown that natural rubber along with other animal proteins trigger this form of contact dermatitis. The molecules associated with this condition are large molecular weight antigens and must therefore usually be aided by some form of previous skin irritation or damage to traverse the skin barrier.
As with other forms of contact dermatitis, the reactions occur at the site of contact with the chemical, and in this way differentiate themselves from other forms of eczema. However, unlike with some other forms of contact dermatitis, urticaria appears to have a genetic aspect to it, with atopic individuals being more susceptible due to their raised allergen-specific IgE plasma levels."
V medical a bit hard to read but could do with more flow and adding whats relevant to the article. whaddya think? relevant anybody? Knowsitallnot 06:28, 14 August 2006 (UTC)
[edit] symptoms
it would be helpful for first time sufferers and first time users of ur website to know the time span within which the hives / welts / edema must appear, under each condition, to more or less confirm that type of urticaria. Docs do help but a little more knowledge goes a long way in prevention. —The preceding unsigned comment was added by 202.78.166.11 (talk) 10:03, 13 April 2007 (UTC).
[edit] Confusing
Just as I was reading through, I thought this was very confusing: Chronic urticaria refers to hives that persists for 6 weeks or more. There are no visual differences between acute and chronic urticaria. Some of the more severe chronic cases have lasted more than 20 years. A survey indicated that chronic urticaria lasted a year or more in more than 50% of sufferers and 20 years or more in 20% of them. Of course this does mean that in almost half the people it clears up within a year and in 80% it clears up within 20 years or less (Champion and others, British Journal of Dermatology 1969). (If my head was in the mood, I would do the math and fix it up...) So I suggest that someone rewrites it a bit to get rid of "Of course this does mean" and rearrange a few of the percentages maybe? —Preceding unsigned comment added by 71.186.54.55 (talk) 03:11, 14 December 2007 (UTC)
QUERY: Does "persists" mean that a person has the same itchy spots in the same places for years without relief? Or does it mean that they get an attack of hives whenever they are exposed to their triggers for years, but the hives go away in between attacks? We can't leave the reader guessing.

[edit] Redundant reference
The following reference seems redundant to the other reference discussing treatment. It doesn't clarify the relationship between CUV1647, and melatonan (or whatever), which would be good to link the two. Also, given the Australian company not having a wikipedia page, mentioning the name of the company doesn't really add anything to the page.
