Allergy is a complication that occurs when the immune system overreacts to certain substances known as allergens. If you have an allergy, your body identifies allergens as foreign harmful substances and tries to destroy them. Common allergens include insects’ venom, dust, pet dander, and pollen. When your immune system reacts to allergens, it produces a chemical or antibody known as immunoglobulin E (IgE). Production of this antibody is a part of your immune system’s attempt to destroy the allergen and protect the body. In this process, IgE antibody signals other immune cells to release inflammatory chemical called histamine. Excess of histamine in the body causes an unwanted response that causes irritation to the skin, lung, eyes and throat. Causes of Allergy There several types of allergies , depending on the cause. Some of them are seasonal while others occur year round. The most common allergies or their corresponding allergens include: ·      ...

Allergies are your body's reaction to a substance it views as a harmful “invader.” For example, coming into contact with what is normally a harmless substance, such as pollen, might cause the immune system (the body's defense system) to react. Substances that cause these reactions are called allergens. What is an allergic reaction? An  “allergic reaction ” is way the body responds to the allergen. A chain of events occur that result in an allergic reaction. The first time an allergy-prone person is exposed to a specific allergen (such as pollen), the body responds by producing allergic (IgE) antibodies. The job of these antibodies is to find molecules of the offending substance in the bloodstream and tissues and to usher them to the body's mast cells (a type of white blood cell) for destruction. As the mast cells destroy the allergens, a chemical called histamine is released into the bloodstream. A large amount of histamine swells body tissues (inflammation), causes...

Hospitals are charged with responsibility of keeping patients wee and safe. Safety and wellness are closely linked as patient safety concerns usually tie directly into patient’s health concerns. Medication errors, diagnostic errors and acquired infections are a few issues that cause health safety concerns. These  patient safety issues  and many others will continue to flow in every year. Some of them are long established and will remain in the forefront of providers’ minds for years to come. Below are 8 patient safety issues you should know: 1.        Medication Errors According to recent statistics about 1.5 million U.S patients experience adverse effects every year due to medication errors. This issue has incurred healthcare system extra costs of about $3.5 billion when trying to deal with the problem. Recent research suggests that medication errors are largely caused by communication errors between patients and healthcare pro...
