Urticaria (hives) Urticaria is the medical name for hives. These scars, pink tumors that arise in any area of skin. They itch and each hive lasts a few hours before disappearing, leaving no trace. New hives appear as older areas disappear. They can be a pea or register to cover wide areas of the body. Although itching may be intense, the skin is usually not scurvy or broken. Some people burn or sting hives. Beehives are often 10-20 percent of people with at least one episode in his life. Rash may occur in the deeper tissues of the eye, mouth, hands and genitals. This area rug to develop a tumor that looks scary, but usually is less than 24 hours. This swelling is called edema. In many cases, an attack of hives associated with infection or a virus and go away within a few days to several weeks. Some people get repeated attacks that occur as an allergic reaction to different things (food, often nuts, chocolate, fish, tomatoes, eggs, fresh berries and milk, insect stings and medications). In this case, they usually break down within hours after exposure. Typically, patients investigate themselves, and they never bother coming to the doctor. Some people may develop ongoing hives from sunlight, cold, pressure, vibration or exercise. This so-called physical urticarias. If hives develop from scratching and rubbing it firmly into the skin it is called dermatographism. It is the most common physical urticarias and affects about 5 percent of the population. It does not always itch. This condition sometimes occurs with other forms of hives. Some people react to everything that makes them hot and sweaty from the hive. It can be sunlight, exercise, warm baths, blushing or anger. These tiny severe itching rash with large red stain around them and called cholinergic urticaria. Pressure urticaria appears as a deep scar in the long-term pressure. Sometimes people react to cold. Even more rare is a reaction to sunlight. Sometimes, people continue to be hives for many years. These hives, called chronic urticaria can be one of the most frustrating problems dermatologists see in lasix without prescription their patients. It is defined as urticaria lasts longer than 6 weeks. Patients, as happened in miserable and worried by this problem, often seeing several specialists. Neither patient nor doctor can determine the cause of urticaria. Patients often say it must be something causing these hives. In fact, it is difficult to accept for some patients. In most cases this is not what causes chronic urticaria, it is nothing. That is, about 95% of cases of chronic urticaria, urticaria is idiopathic (medical term which means that no significant reason). After those 5% of cases the reason should consult a doctor to determine whether the underlying disease is present (eg thyroid problems, liver, skin diseases, sinusitis), or if allergic causes (eg, reaction to medication, insect food etc.). This can be achieved by a good history and physical, some blood and urine, and sometimes the skin. Some patients with chronic urticaria and elevated thyroid antibodies in the blood will improve when given thyroid supplements, even if thyroid function is normal. Approximately half of patients with chronic idiopathic urticaria, due to the fact that the body's immune system, in a sense, overactive. Urticaria is autoimmune. The immune system attacks normal body tissues and cause a rash as a result. We know that some are suffering from urticaria and other signs of autoimmune problems. Some of them have autoimmune thyroid disease, swollen joints, or some deviation in the blood (especially in the test ANA). New treatments recently developed autoimmune urticaria. This use plakvenyl, the drug initially used to combat malaria. At last the 83% improved or completely cleared using for three months or more. Thus, many patients with chronic urticaria, in fact no influence (drugs, food, insect, chemical) guilty of urticaria. The patient must understand and accept it at perfect control. Basically, all you need do is to treat hives. The main treatment of urticaria is antihistamines, and they will work if used properly. Common reasons for lack of effectiveness of antihistamines: 1) features an antihistamine used is not strong enough 2) antihistamines is available in very high doses of 3) antihistamines does not last for quite a long period. The most well-tolerated initial treatment nesedatyvni antihistamine Claritin. Zyrtec is similar, but sometimes can cause sedation. If it does not eliminate the rash, sedative type antihistamine (Hydroxyzine, tsiprogeptadin or doksepin) is added at night. High doses may be necessary and this will cause sedation. Fortunately, most patients will be less inclined to comfort after they took the drug regularly for some time.
(steroids) to clear the hives completely. Then the patient can maintain an action in a much safer antihistamines, since steroids have significant side effects if used long term. The drug used to treat psoriasis and kidney transplantation is almost always effective in cleaning even the most difficult cases of chronic hives in small doses. However, it causes serious side effects when taking a long time. There are other medications that can be added to antihistamines, but these non-standard treatments are not always effective. However, if the rash does not respond, they should try. Examples are anti-acid tablets (Tagamet, Zantac), dapsone and sulfasalazine (anti-inflammatory antibiotics), nifedipine (blood pressure medicine), Accolate (asthma drug), colchicine (for gout drug), and others. It is important that the patient receives enough medication (antihistamines, possibly in combination with other drugs) to suppress the hives. How would it not that the control patients rash, should be daily routine, taking drugs every day, regardless of their hives in any day. The idea is that one interferes with hives breakout. Some doctors believe that treatment should be continued for a long time - maybe even a month after the hives disappeared. Again, the exception is a cortisone / steroid-type drugs to be used only for short periods at first calm down urticaria. Remember to work closely with your doctor to find a cure mode, which suppresses the hives until they are themselves. .
