Each year I see hundreds of new patients with complaints of hives and swelling. Hives are intensely itchy skin rashes that resemble welts and can occur anywhere on the body. They typically arise without warning and about half the time, are accompanied by angioedema, a deeper swelling in the skin. "Urticaria" is the technical term for hives. These skin eruptions generally last for several hours but rarely for more than twenty four hours. Hives which come and go for more than six weeks are considered chronic urticaria (CU).
Acute hives are more short-lived (less than six weeks) and often don't require an allergy specialist. Foods or drugs are common triggers of acute urticaria but triggers associated with chronic urticaria are more difficult to identify. In fact, 80-90% of the time doctors are unable to determine the cause of chronic urticaria despite comprehensive testing.

Let me tell you a tale of two Deborahs, and two different ways to handle stress. The first tale takes place in 1993. I was working at the corporate headquarters of a bookstore chain. Although I was doing a good job and getting stellar performance reviews from a very exacting boss, the company was in trouble. There had already been one round of layoffs, and another was expected. I wasn't worried about losing my job, but I was being given more and more work. Most of it involved running reports and analyzing data in a frantic attempt to find ways to prove to our parent company, Kmart, that we really were doing well in sales. Being overburdened with doing work that you know is not going to be enough to keep your coworkers from being laid off is a recipe for being pretty stressed out.
At the time my desk was right near a conference room. Despite the belt-tightening, food was served during at least one meeting a day in that conference room. So a lot of extra food made its way to the ...
Drug-induced immune hemolytic anemia is a blood disorder that occurs when a medicine triggers the body's defense (immune) system to attack its own red blood cells. This causes red blood cells to break down earlier than normal.

Causes, incidence, and risk factors
In some cases, a drug can cause the immune system to mistakenly think your own red blood cells are dangerous, foreign substances. Antibodies then develop against the red blood cells. The antibodies attach to red blood cells and cause them to break down too early.
Drugs that can cause this type of hemolytic anemia include:
Cephalosporins (a class of antibiotics)
Penicillin and its derivatives
Some nonsteroidal anti-inflammatory drugs (NSAIDs)
There are many other rarer causes of drug...
