Irritated skin can be caused by a variety of factors. These include immune system disorders, medications and infections. When an allergen is responsible for triggering an immune system response, then it is an allergic skin condition. Atopic Dermatitis (Eczema), Eczema is the most common skin condition, especially in children. It affects one in five infants but only around one in fifty adults. Allergic Contact dermatitis occurs when your skin comes in direct contact with an allergen.

Drug allergies are a group of symptoms caused by an allergic reaction to a drug (medication). Adverse reactions to drugs are common. (adverse means unwanted or unexpected.) Almost any drug can cause an adverse reaction. Reactions range from irritating or mild side effects such as nausea and vomiting to life-threateninganaphylaxis. A true drug allergy is caused by a series of chemical steps in the body that produce the allergic reaction to a medication.  

When an allergy instigating substance, known as an allergen, enters the body, the immune system can cause succession of physical reactions, inclusive of blood vessel dilation and the production of inflammatory substances or mediators, such as histamine. Histamine causes common general allergy symptoms such as itchy and watery eyes, sneezing, stuffy nose, and a runny nose. 

Allergies can cause many ear, nose, and throat signs. Children with nasal allergies are at greater risk for developing asthma. Nasal allergies can cause sneezing, itching, nasal rubbing, nasal congestion, and nasal drainage

Allergies may play role in ear infections, fluid behind the eardrum, or problems with troublesome ear pressure. Diagnosing and treating allergies may be an important part of healthy ears.

Allergies may lead to the disposition of too much mucus which can make the nose run or drip down the back of the throat, leading to "post-nasal drip." It can lead to cough, sore throats, and a husky voice.

A food allergy or hypersensitivity, is an abnormal response to a food that is triggered by the immune system. The immune system is not responsible for the symptoms of a food intolerance, even though these symptoms can resemble those of a food allergy. Food allergies involve two features of the human immune response. One is the production of immunoglobulin E (IgE), a type of protein called an antibody that circulates through the blood. The other is the mast cell, a specific cell that occurs in all body tissues but is especially common in areas of the body that are typical sites of allergic reactions, including the nose and throat, lungs, skin, and gastrointestinal tract.

Allergies and hypersensitivity to certain substances are considered immune system disorders. When the immune system does not function properly, it leaves the body susceptible to an array of diseases. Allergies are disorders of the immune system. Most allergic reactions are a result of an immune system that responds to a "false alarm." When a harmless substance such as dust, mold, or pollen is encountered by a person who is allergic to that substance, the immune system may react dramatically by producing antibodies that "attack" the allergen (a substance that produces allergic reactions). The result of an allergen entering a susceptible person's body may include wheezing, itching, runny nose, watery or itchy eyes, and other symptoms.

Allergy shots help your body get used to allergens, the things that trigger an allergic reaction. They don’t cure allergies, but eventually your symptoms will get better and you may not have allergic reactions as often. Allergy shots, also called "immunotherapy," may work for you if allergy drugs don’t work well or you have symptoms more than three months a year. Allergen immunotherapy changes the way the immune system reacts to allergens, by switching off allergy. The end result is that you become immune to the allergens, so that you can tolerate them with fewer or no symptoms.  

It is very important to make the diagnosis of occupational allergies as early as possible because if there is a long delay before diagnosis the asthma may not improve on removal from exposure, and persist indefinitely. Exposure to organic dusts, chemicals, or animals at work can cause the development of all sorts of allergic responses. The clinical history usually provides the first clue by the association of symptoms with work, and recovery with absence from work, but it is seldom so clear-cut because prolonged reactions are common, and daily exposure adds up towards the end of the week.

If your child suffers from allergies or other problems with his immune system is Pediatric Allergy. Child’s immune system fights infections. If your child has allergies, her immune system wrongly reacts to things that are usually harmless. Pet dander, pollen, dust, mold spores, insect stings, food, and medications are examples of such things. This reaction may cause her body to respond with health problems such as asthma, hay fever, hives, eczema (a rash), or a very severe and unusual reaction called anaphylaxis.

A variety of air pollutants have been attracting attention as one causative factor. Epidemiological and toxicological research suggests a causative relationship between air pollution and the increased incidence of asthma, allergic rhinitis, and other allergic disorders. These include ozone, nitrogen dioxide and, especially particulate matter, produced by traffic-related and industrial activities. Strong epidemiological evidence supports a relationship between air pollution and the exacerbation of asthma and other respiratory diseases.

Allergic conjunctivitis or ocular allergy, eye allergy occurs when something you are allergic to irritates the conjunctiva. This is the delicate membrane covering the eye and the inside of the eyelid. Like all allergies, allergic conjunctivitis starts when the immune system identifies an otherwise harmless substance as an allergen. This causes your immune system to overreact and produce antibodies called Immunoglobulin (IgE). Theseantibodies travel to cells that release chemicals which cause an allergic reaction. In this case, allergic reactions include eyes that water, itch, hurt or become red or swollen.

Insecting allergy can develop at any age and usually manifests after several uneventful stings. The severity of an insect sting reaction varies from person to person. There are three types of reactions- normal, localized and allergic.  A normal reaction will result in pain, swelling, and redness around the sting site. 

The role of infection in asthma is presently a paradox. While respiratory syncytial virus, among others, has long been believed to instigate immunological changes which lead to asthma, and rhinovirus might be an important contributory factor in the exacerbation of asthma symptoms in children and adults, there is increasing speculation that infections in early life have a protective role in the development of allergy and asthma. 

There are many factors involved in an accurate diagnosis and an effective treatment plan. Allergy skin testing is the gold standard and is used along with the medical history to establish a diagnosis. Both blood and skin allergy tests can detect a patient’s sensitivity to common inhalants like pollen and dust mites or to medicines, certain foods, latex, venom, or other substances. When it comes to human allergic disease, an individual’s medical history is as important as the results of an allergy test.

Allergic diseases such as allergic rhinitis represent a global health problem, affecting 10%–25% of the world population. There is clear evidence to support the concept that allergic diseases are influenced by genetic predisposition and environmental exposure. Polymorphisms of candidate genes have been associated with clinical expression of these diseases..

The advent of molecular techniques has resulted in the ability to tailor medications to specific protein targets. Such therapies are known as biologic immunomodulators, or more commonly, biologics. Since their introduction, these therapies have been designed to specifically target the molecular pathways involved in the pathogenesis of various autoimmune and inflammatory disorders.

Veterinary Allergy is the first comprehensive, high quality reference dealing with all aspects of veterinary allergy in all species and all body systems involved with allergy. Providing solid breadth and excellent depth of coverage, it deals with the immunopathology of the various allergic conditions as well as with clinical presentation, diagnosis and treatment of veterinary allergic diseases.  

Primary immunodeficiency diseases (PI) are a group of more than 250 rare, chronic disorders in which part of the body’s immune system is missing or functions improperly. While not contagious, these diseases are caused by hereditary or genetic defects, and, although some disorders present at birth or in early childhood, the disorders can affect anyone, regardless of age or gender. Some affect a single part of the immune system; others may affect one or more components of the system.come red or swollen.

Analysis of genetically engineered mice and biochemical studies continue to help unravel the molecular pathways that drive allergic inflammatory reactions. The knowledge acquired may lead to novel approaches for suppressing allergic inflammation.

The development of cancer therapies is increasingly dependent on our understanding of tumor biology, andbiomarkers—especially predictive biomarkers—are crucial tools in the field of personalized medicine and health economics, in particular, as they enable definition of the populations of patients who are most likely to benefit from targeted therapies.

FARE has a variety of resources designed for specific audiences such as school professionals, health professionals, and restaurant and food industry professionals.These tools are available to help you in turn teach staff members the essentials behind food allergy management to help individuals safe from reactions. Some of the resources found here are published under the Food Allergy & Anaphylaxis Network name. We will be rebranding many of our materials in the coming year.

An allergist/immunologist can provide expert consultation for a number of diseases and conditions. These can be divided into two broad categories: 1) chronic diseases frequently followed by primary care physicians or another specialist/sub-specialist, and 2) conditions in which allergist/ immunologist consultation is usually necessary for definitive diagnosis and treatment.

The primary utility of feminist ethics theory in policy development is the ability torefocus the underlying motives of decisions executed by health professionals. Byincorporating the most basic interpretations of feminist critiques in decision-making processes, health professionals raise their awareness and sensitivity towards the fact that health policies will have a direct impact on the lives of others, whether this impact will be observed by the health professional or not.
