Hypersensitivity is an excessive, harmful immune reaction to antigens. Type I hypersensitivity is also known as immediate hypersensitivity, because usually occurs 15 to 30 minutes after exposure to an antigen (allergen). When an allergen enters the body, selected plasma B cells produce allergen-specific immunoglobulin E(IgE). In Type I hypersensitivity, allergens bind to IgE on the membranes of basophils and mast cells, stimulating them to release preformed mediators like histamine, tryptase and others. This chemicals trigger glandular secretion and capillary permeability, causing clinical signs of local edema, mucus hypersecretion, congestion, watery eyes, and itchiness. It also produces smooth muscle spasms causing bronchospasms, vomiting,

... immune system. The body’s immune system is beneficial to rid of illness and foreign invader our body note to be a threat such as parasite, virus, or bacteria but sometimes it can also reacts to a harmless substance. As a result to protect out immune system, the body manufacture a protective protein barrier called antibodies. This protective agent exhibit swelling and inflammation of tissues whenever an allergic reaction occurs as a response to eliminate the threat (Burks, Harthoorn,Van Ampting, Oude Nijhuis, Langford, Wopereis, & Harvey, 2015). In addition, the anatomical systems of babies are still developing in the sense that, they have small, sensitive airways in their lungs. In a situation of allergy contact, the airways become swollen as a result to rid virus and bacteria; and in response, babies start to cough, sneeze and can progress to wheezing and asthma.
Anaphylaxis shock occurs when someone who is sensitive to a substance they are exposed to which results in constricted airway and possible inability to breathe. Parents with children that experience any form of allergic reaction most notify the day care provider so appropriate precautionary steps are taken to maintain a safe health environment for these children. As allergy conditions have slowly increased within our society day care providers have taken more aggressive action to protect these children by extending a “peanut free environment” within the school setting. The percentage of children who experience their first allergic reaction outside the home has increased by 77% over past years daycare providers need to be trained and prepared to handle all types of allergic reaction situations. Steps that a provider and parent should take are as follows: 1. Food allergy action plan, 2. Inform all staff, 3. Post child’s name and allergy,
In a latex allergy, your immune system identifies latex as a harmful substance. With wheezing, runny nose or anaphylaxis, your immune system triggers certain cells to produce immunoglobulin E (IgE) antibodies to fight the latex component (the allergen). The next time you come in contact with latex, the IgE antibodies sense it and signal your immune system to release histamine and other chemicals into your bloodstream. The more exposure you have, the more your immune system is likely to respond to latex (sensitization). These chemicals cause a range of allergic signs and symptoms. Histamine is partly [sic] responsible for most allergic responses. (ACAAI)
You have close relatives with allergy (that is, a mother, father, sister, brother, aunt, uncle, or child)
In most situations, genetic heredity plays a role in what allergy a person acquires. Children inherit their allergy from their parents. (Mills et al., 2007) On the contrary, some of individuals develop certain allergies in spite of their parents. One proposed theory that will be explored in this paper is whether or not the use of vaccines causes us to develop certain allergies. Before that theory can be proven as right or wrong, we must first get a more thorough understanding of the immune system.
Developing allergies that people are unaware of can be very scary and dramatically life changing. Some of the effects that allergies can cause can be troubling and they might happen multiple times before
Atopic dermatitis is a recurring skin condition that is characterized by inflammation and itching of the skin. In Atopic dermatitis, which can also be referred to as atopic eczema the patient has signs of redness and scaly skin. It is often accompanied by asthma and hay fever, but not always. Approximately thirty percent of children who have eczema will develop asthma later in life. Most people who develop eczema will have an outbreak before the age of two. It is estimated that only ten percent of people diagnosed with eczema are diagnosed after the age of five. It is important for eczema to be diagnosed early to prevent the recurrence of future outbreaks. Seeking treatment early can decrease sleep disturbances, scarring, discomfort, and skin infections.
Most of you may not think of asthma as a killer disease, yet more that 5,000 Americans die of asthma each year. According to the Mayo Clinic web page, asthma also accounts for more that 400,000 hospital discharges annually. As the number of people with asthma increases, the more likely you are to come in contact with a person who has the disease. As far as I can remember, I have had asthma my whole life. My mother and one of my sisters also have asthma, so I have a first hand experience with it. This morning, I will discuss some interesting facts about asthma, I will specifically focus on what it is, warning signs, symptoms, causes, and the treatments that are used.
Human race is known to have developed numerous allergies to various known and unknown allergens. An extreme allergic reaction which can be “life-threatening”. (Mydr.com.au, 2014) is referred to as Anaphylaxis.It is a “medical emergency”(Lloyd & Sisman,2013).Statistics indicate that maximum deaths occur due to allergic reactions of various medicines. The other causative agents can be insects, food, latex, hair dye, etc(Lloyd & Sisman,2013). The most common trigger to stimulate anaphylaxis among children are food products such as peanuts, dairy, seafood etc. Exposure to any of these allergens can result in severe anaphylactic attack within 20 minutes.(Australian Resuscitation council, 2012).However the doctors discuss the history of symptoms occurring in children suffering with peanut allergy before declaring them to be anaphylactic and prescribing medication. (Unknown, 2014). Symptoms of anaphylaxis may occur in varied forms depending upon the severty of the reaction. For instance in mild cases swelling of lips, eyes or face occurs along with hives, rash, tingling of mouth and vomitting accompanied with abdominal pain. Nevertheless in extreme conditions the former symptoms may be accompanied with noisy breathing, wheezing, hoarseness and unconsciousness. (Lloyd & Sisman,2013).
In such a situation when the allergens enter the body, the immune system overreacts and may show some severe physical symptoms. The symptoms are given below
“Just because the people are average don’t mean that you've got to be average.” Many people want to fit into a crowd, so they will change the way the act. In this quote it says that just because people around you are average doesn't mean that you have to be average. It is telling the viewer that you don't have to have to average just because your pears are average. You can be successful and great even though people around you are just average I agree with this quote because many people want to fit in the crowd of people they are around with.
This article explores the increasing hypersensitivity of college students. Universities are protecting students against uncomfortable ideas, which leads to vindictive protectiveness; vindictive protectiveness can encourage more hostile and violent responses to various microaggressions. Furthermore, social media has led to an increasing amount of vindictive protectiveness, since students are coming together on a global scale to campaign more easily. Combined together, these negative thoughts against different viewpoints discourages critical thing. As a result, this is weakening American democracy and the workforce because it does not prepare students to succeed in a world full of diverse viewpoints.
Patients who usually have allergies suffer from many symptoms due to the allergic reaction(s). Normally, your immune system protects you against invading agents such as bacteria and viruses. Otherwise harmless allergens (allergy-producing substances) cause your body to react as if they were dangerous invaders. In effect, your immune system is responding to a false alarm.
Experiencing allergic reactions are generally more common on days that have higher pollen counts and stronger winds.
