Talk:Urticaria

Types
Pressure also

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)

My husband has urticaria caused by the pathogenic sub-types of Blastocystis hominus. [Proteases in the central vacuole of these parasites induce the activation of specific clones of Th2 lymphocytes, the release of related proinflammatory cytokines, and, consequently, the production of IgE.] Detailed information about this type of urticaria (and the role of B. hominus in its etiology) can be found in the last four issues of Parasitology Research.

I'm curious about streptococcus induced urticaria. Is there a reference anywhere for that? Claire --ClaireMullan (talk) 08:32, 15 March 2008 (UTC)

I have seen a version called artificial urticaria. Shows a woman and pictures here. I think its weird and cool at the same time... --Rootbear75 (talk) 07:20, 1 December 2008 (UTC)

What about hemorrhagic urticaria? Mkayatta (talk) 22:57, 18 December 2008 (UTC)

In the section titled "cholinergic and stress," there are a couple of things I don't get. First, in the sentence that reads, "It precisely becomes marked (etc.)," is it the becoming or the marking that is precise? Second, the reference to jogging instead of riding a stationary bike has me wondering why the patient was asked to change activities.1canuckbuck (talk) 08:46, 21 January 2013 (UTC)

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?


 * Mwah. It's possible. JFW | T@lk  20:31, 4 December 2005 (UTC)


 * 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)

Simple, unexpected source of relief: I had hives for pretty close to 10 years. My hives were usually associated with heat and pressure. I was original diagnosed and treated by a good allergy specialist who prescribed a small dose of prednisone for close to a year after the less risky drugs brought no relief. The doctor then said I needed to learn to live with it because the prednisone was too risky. Like most others, the hives were pretty disruptive to my life. I had to give up golf, carrying the grandkids was an invitation to trouble and I was even careful about the types of chairs I would sit in because, for example, wooden chairs with ladder backs would often generate welts. I never had any extended periods where I without the hives. I hope you get the picture. About 4-5 months ago, I decided I wanted to lose some weight. As part of this, I cut back on the amounts I was eating at meals and I started drinking a glass or two of V8 juice daily, since vegetables haven't been part of my diet. Since I started drinking the V8 juice I have not had any problems with hives except for a brief period during a holiday trip when I didn't drink any V8 juice. Clearly this is not a scientific study and it might be that something else in my life has changed which is more directly related. For now, though, I believe it's related to the V8 juice. I am thrilled that I have this under control with something simple and if it just one other person benefits, then that would be awesome! Craigjh (talk) 06:03, 8 February 2010 (UTC)

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)

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)

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)

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).

Confusing
Just as 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.

 * Yes, this is confusing, but so is the immune system. —Preceding unsigned comment added by 85.156.24.108 (talk) 22:23, 22 January 2009 (UTC)

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.

HIVES
I have also having problems with itchy skin, and only notice the change with the change in laundry degentent. Currently decided to change the degentent, so as to determine the change in myself, can only confirm at a later stage when the change is made. thanks for all your coments, very informative. —Preceding unsigned comment added by 196.15.199.123 (talk) 08:17, 3 October 2008 (UTC)

Contradiction
There's a strange contradiction here. This article says "Less common causes of hives include friction, pressure, temperature extremes, exercise, and sunlight." while Dermatographic urticaria says "Dermatographic urticaria [...] is one of the most common types of urticaria". What gives? Is friction/pressure one of the most common causes or one of the least common ones? 145.99.155.53 (talk) 20:36, 27 July 2009 (UTC)
 * As an additional and related contradiction, the page for Dermatographic urticaria says that DU is one of the LEAST common forms of urticaria, but here it's listed as one of the MOST common forms. Which of these pages is correct? Metheglyn (talk) 08:19, 28 November 2013 (UTC)

Tartrazine, not thorazine
I have no idea how to edit on here, but I noticed a mistake right away when reading this entry and someone needs to fix it. In the dietary section a study is mentioned that used food additive "E102" and it has been mistakenly referred to as Thorazine. Thorazine is an old school antipsychotic that was used to treat schizophrenic and bipolar patients. The name of food additive E102 is actually Tartrazine. —Preceding unsigned comment added by 69.114.7.189 (talk) 21:31, 8 July 2010 (UTC)

Hives and H. Pylori
Hives alone, or when associated with stomach problems like ulcers and gastritis is very likely caused by H. Pylori, why is H. Pylori down-played in this article by using the words "less likely"?

H. Pylori is common in 50% of the world population and in 70% of children. Most people do not have symptoms or adverse reactions, but if all in a family unit are not treated, then the family member who is suffering can be easily re-infected through oral/oral or fecal/oral contamination. The association of hives and H. Pylori should not be down-played and maybe should even have it's own section so that people can be well informed.

The test for H. Pylori is quite non-invasive and inexpensive with a simple breath test. After two days, you know the result and usually a 14 day cycle of two (2) anti-biotics are prescribed.

 * If you have a change to make to the article based on reliable sources, then please suggest that change or, if you prefer, edit the article. A suggestion here (with references) would be ideal.
