What is the definition of allergies

American Academy of Allergy, Asthma, and Immunology

This academy’s website provides valuable information to assist readers determine the difference between colds, allergies, and sinusitis. A primer guide on sinusitis also provides more specific information about the chronic version of the illness. Additional resources include a «virtual allergist» that helps you to review your symptoms, as well as a database on pollen counts.

American College of Allergy, Asthma, and Immunology (ACAAI)

In addition to providing a comprehensive guide on sinus infections, the ACAAI website also contains a wealth of information on allergies, asthma, and immunology.

The site’s useful tools include a symptom checker, a way to search for an allergist in your area, and a function that allows you to ask an allergist questions about your symptoms.

Asthma and Allergy Foundation of America (AAFA)

For allergy sufferers, the AAFA website contains an easy-to-understand primer on sinusitis. It also provides comprehensive information on various types of allergies, including those with risk factors for sinusitis.

Centers for Disease Control and Prevention (CDC)

The CDC website provides basic information on sinus infections and other respiratory illnesses, such as common colds, bronchitis, ear infections, flu, and sore throat.

It offers guidance on how to get symptom relief for those illnesses, as well as preventative tips on practicing good hand hygiene, and a recommended immunization schedule.

U.S. National Library of Medicine

The U.S. National Library of Medicine is the world’s largest biomedical library. As part of the National Institutes of Health, their website provides the basics on sinus infection. It also contains a number of links to join you with more information on treatments, diagnostic procedures, and related issues.



In most cases, people with allergies develop mild to moderate symptoms, such as watery eyes, a runny nose or a rash.

But sometimes, exposure to an allergen can cause a life-threatening allergic reaction known as anaphylaxis. This severe reaction happens when an over-release of chemicals puts the person into shock.

What is the definition of allergies

Allergies to food, insect stings, medications and latex are most frequently associated with anaphylaxis.

A second anaphylactic reaction, known as a biphasic reaction, can happen as endless as 12 hours after the initial reaction.

Call 911 and get to the nearest emergency facility at the first sign of anaphylaxis, even if you own already istered epinephrine, the drug used to treat severe allergic reactions. Just because an allergic person has never had an anaphylactic reaction in the past to an offending allergen, doesn’t mean that one won’t happen in the future.

If you own had an anaphylactic reaction in the past, you are at risk of future reactions.

Semiochemical:

Chemical that affects the behaviour of an organism. Such chemicals include pheromones, which are used for communication between members of the same species, and allelochemicals, which act as chemical signals between members of diverse species. [Source: FAO Efficacy guidelines]

Safety factor:

Composite (reductive) factor by which an observed or estimated no-observed-adverse- effect level (NOAEL) is divided to reach at a criterion or standard that is considered safe or without appreciable risk. Also referred to as: Assessment factor, Uncertainty factor. [Source: IPCS/OECD]

Skin irritation:

Production of reversible damage to the skin following the application of a test substance for up to 4 hours.

[Source: GHS]

Specific Target Organ Toxicity – Repeated Exposure (STOT-RE):

Production of specific, non-lethal target organ toxicity arising from a repeated exposure to a substance or a mixture. Every significant health effects that can impair function, both reversible and irreversible, immediate and/or delayed – and not specifically addressed in the relax of the GHS – are included. [Source: GHS]

Specification:

Parameters and criteria defining the physical appearance and physical and chemical properties of technical and formulated pesticides linked with hazard and risk profiles.

[Source: International Code of Conduct]

Supervised trials (for estimating maximum residue levels):

Scientific studies in which pesticides are applied to crops or animals according to specified conditions intended to reflect commercial practice after which harvested crops or tissues of slaughtered animals are analysed for pesticide residues. Generally specified conditions are those which approximate existing or proposed GAP. [Source: JMPR]

Specific Target Organ Toxicity – Single Exposure (STOT-SE):

Production of specific, non-lethal target organ toxicity arising from a single exposure to a substance or a mixture.

Every significant health effects that can impair function, both reversible and irreversible, immediate and/or delayed – and not specifically addressed in the relax of the GHS – are included. [Source: GHS]

Skin sensitizer:

Substance that will lead to an allergic response following skin contact. [Source: GHS]

Subchronic:

Repeated over a short period, generally about 10 % of the life span; an imprecise term used to describe exposures of intermediate duration. Also referred to as “subacute”. [Source: IUPAC]

Subchronic toxicity test:

Animal experiment serving to study the effects produced by the test substance when istered in repeated doses (or continually in food, drinking water, air) over a period of up to about 90 days.

[Source: IUPAC]

Synergism (in toxicology):

Pharmacological or toxicological interaction in which the combined biological effect of exposure to two or more substances is greater than expected on the basis of the simple summation of the effects of each of the individual substances.

Skin corrosion:

Production of irreversible damage to the skin; namely, visible necrosis through the epidermis and into the dermis, following the application of a test substance for up to 4 hours. Corrosive reactions are typified by ulcers, bleeding, bloody scabs, and, by the finish of observation at 14 days, by discolouration due to blanching of the skin, finish areas of alopecia, and scars.

Histopathology should be considered to assess questionable lesions. [Source: GHS]

Supervised trials median residue (STMR):

Expected residue level (expressed as mg/kg) in the edible portion of a food commodity when a pesticide has been used according to maximum GAP conditions.

What is the definition of allergies

The STMR is estimated as the median of the residue values (one from each trial) from supervised trials conducted according to maximum GAP conditions. [Source: JMPR]

Sensitization:

Two-phase process including i. Induction of specialized immunological memory in an individual by exposure to an allergen; and ii. Elicitation, i.e. production of a cell-mediated or antibody-mediated allergic response by exposure of a sensitized individual to an allergen. [Source: GHS]

Serious eye damage:

Production of tissue damage in the eye, or serious physical decay of vision, following application of a test substance to the anterior surface of the eye, which is not fully reversible within 21 days of application.

Benadryl

Generic Name:diphenhydramine (DYE fen HYE dra meen)

Medically reviewed by Sanjai Sinha, MD Final updated on Dec 18, 2018.


What is Benadryl?

Benadryl (diphenhydramine) is an antihistamine that reduces the effects of natural chemical histamine in the body.

Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Benadryl is used to treat sneezing, runny nose, watery eyes, hives, skin rash, itching, and other freezing or allergy symptoms.

Benadryl is also used to treat motion sickness, to induce sleep, and to treat certain symptoms of Parkinson’s disease.


Important information

You should not use Benadryl to make a kid sleepy.

When taking Benadryl, use caution driving, operating machinery, or performing other hazardous activities. Diphenhydramine may cause dizziness or drowsiness.

What is the definition of allergies

If you experience dizziness or drowsiness, avoid these activities.

Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while taking Benadryl.

Do not give this medication to a kid younger than 2 years ancient. Always enquire a doctor before giving a cough or freezing medicine to a child. Death can happen from the misuse of cough and freezing medicines in extremely young children.
