Common causes and treatment of ‘Allergy’

Monday, April 21st, 2014

An allergy is defined as an overreaction to usually harmless substance that the immune system determines is harmful, even if it is not. When the immune system is challenged with an allergen (substance which causes an allergic reaction) it becomes sensitized, committing the allergen memory. From that moment forward, the immune system recognizes the allergen and sets up a defense by releasing the chemical into the blood that may cause various symptoms.
Diagnosis of allergy is mainly depends upon carful history, habits, symptoms, physical examination. In case of food allergy elimination diet and food diary should be maintained. Laboratory tests mainly include skin and blood tests.
A doctor will base the diagnosis on a physical examination and your symptoms. In most cases, a doctor will suspect that your problem is a drug allergy if you have a history of allergic reactions after the use of certain medications.
Skin tests sometimes can be used to determine if someone has an allergy to a medication. Penicillin skin testing, for example, involves an injection just beneath the skin of a small amount of one part of the penicillin molecule. People with a penicillin allergy will develop a reaction at the site of injection that can be measured. However, these tests are not always reliable since only a part of the penicillin molecule is injected. This test often is used for a person who needs a penicillin-like drug to treat a serious infection.

 

Viral fever can happen at anyplace with anyone

Wednesday, April 9th, 2014

During the monsoon season, a typical viral syndrome grips the region. The symptoms include fever, burning in eyes, running nose (coryza), sore throat, loose motions, etc. It is a self-limiting disorder and the symptoms will reduce on its own within five days. There is no need to take any antibiotics, as it will only aggravate the problem.

Headaches, body aches and a skin rash characterise most of these viral fevers. They may affect any age group, and are seen world-wide. They require only symptomatic treatment. Some are highly contagious. Most of them are not dangerous and self-limited, but some can progress rapidly leading to death.

Several microorganisms, such as bacteria, viruses, fungi and other types of germs enter the human body, almost every single day. The immune system usually fights off these microorganisms, which keeps them from causing any major problems, within the body. However, there may be times when the immune system cannot fight all of them and eliminate them from the body.

When a person’s immune system fails to fend off these harmful viruses, they usually cause an infection in the body, which subsequently leads to a viral fever. Hence the term viral fever can be used for several types of infections that have been caused by viruses. Although viral fevers are highly contagious and should be strictly avoided, they are fairly harmless and do not lead to any major complications. However, in some instances, the symptoms of a viral fever could worsen rapidly and could lead to other dangerous health conditions, some of which could also be a threat ot the life of the individual.
