▶ My Study Skills Book: • What is it? • Allergic rhinitis consists of the inflammation of the nasal mucosa, it is the most frequent cause of non-infectious rhinitis and is associated with the inflammatory response to environmental or occupational allergic stimuli. This can appear seasonally or throughout the year. • What causes it? • Allergic rhinitis, as its name denotes, is caused by some allergenic stimulus. Generally in its seasonal variety it is caused by plant allergens that vary according to the season. • In spring it can be caused by: tree pollens (eg, oak, elm, maple, alder, birch, juniper, olive) • During the summer, it is caused by grass pollens (eg, honey grass, timothy grass, colored grass, dactyl, Johnson's grass, or Aleppo sorghum) and weed pollens (eg, Russian thistle, plantain) • Finally in Autumn it is caused by other weed pollens (eg ragweed) • In some populations, symptoms can also be caused by airborne fungal spores. • Essentially once the allergen comes into contact with the nasal mucosa, it triggers a series of inflammatory reactions mediated by IgE that favor the release of a substance called histamine, histamine produces the appearance of classic symptoms such as transparent nasal discharge and sneezing. continuous. • What symptoms does it produce? • The symptoms of rhinitis are varied and we can name nasal itching or itching, transparent nasal discharge, continuous or continuous sneezing known as stunned in salvo, nasal obstruction, alterations of smell such as hyposmia and watery eyes. • On physical examination, nasal polyps and bluish-red coloration of the nasal mucosa, eyelid edema, and conjunctival irritation may be found. • As I mentioned at the beginning, it can coexist with conditions such as sinusitis, asthma, dermatitis and conjunctivitis, so there may also be data on these pathologies, in many cases the culprit allergen is the same although it is not the case in all cases. • How is the diagnosis made? • Allergic rhinitis can almost always be diagnosed simply with a good history of the condition and a physical examination. Allergic tests are usually performed in the event of a poor response to initial treatment, in these tests specific allergens can be identified in order to avoid exposure to them. Some of these common allergens are: seasonal pollens, house mite feces, cockroaches, animal dander, and fungi. It can also be supplemented with an allergen-specific IgE test in case skin tests are inconclusive. In rare cases, other studies are carried out in order to rule out complex pathologies or syndromes that can give symptoms similar to allergic rhinitis. • Which is the treatment? • Treatment is usually based on reducing the inflammatory processes that lead to symptoms and reducing exposure to the allergen once identified. • Antihistamine medications such as loratadine, desloratadine, and cetirizine and nasal steroids such as mometasone are used. Among these two, nasal steroids are considered the first-line treatment because of their easy adherence and good response to lessen symptoms. Nasal medications are often preferred over oral medications as they are less systemically absorbed and have fewer adverse effects. • Nasal saline can help mobilize nasal secretions and prevent infections and injuries to the nose. • Immunotherapy is a specialized alternative for patients who are particularly resistant to treatment, and consists of successive exposure to an allergen in order to desensitize the body and reduce symptoms after exposure to this allergen. This therapy can be done with injections or sublingually. • 0:00 Introduction • 0:53 What causes allergic rhinitis? • 2:21 What symptoms does allergic rhinitis produce? • 3:12 How is allergic rhinitis diagnosed? • 4:19 What is the treatment for allergic rhinitis? • 5:42 How can allergic rhinitis be prevented? • 6:48 I answer your feedback questions • • Add yourself to my social networks: • ▶ FACEBOOK: http://bit.ly/2YjFKR2 • ▶ TWITTER: http://bit.ly/2ZpOame • ▶ INSTAGRAM: http://bit.ly/2Yiorzy • ▶ BLOG: https://doctorsindoctorado.com/ • If you are interested in financially supporting the project • ▶ PAYPAL: https://www.paypal.me/TapiaMoreno • ▶ PATREON: https://goo.gl/adEdVh
