Rhinitis is know as many things: 1. Allergenic Rhinitis ( Hay fever ) 2. Non-allergenic Rhinitis 3. Vasomotor Rhinitis 4. Infectionous Rhinitis 5. Hormonal
Allergenic RhinitisSeasonal allergenic rhinitis (hay fever) ismainly an alergy caused by outdoorallergens such as tree, grass, weeds, andmold spores. If you sneeze, have a runny orstuffy nose during spring, summer, or fallyou may have hay fever. Hay fever is themost common type of allergy problems.Symptoms include sneezing, itching, runnyor stuffy nose, and red watery eyes.
NON-ALLERGENIC RHINITISNon-allergenic rhinitis involves chronic sneezing orhaving a congested, drippy nose with no apperentcause. The symptoms are similar to thoses of hayfever, but there is no allergic reactions involved.Nonallergic rhinitis can affect children and adults,however is more common over the age of 20. Moreannoying than harmful, it can be triggered byodors, irritants, weather, certain foods, or anotherunderlying condition. A diagnosis of nonallergenicrhinitis is given after allergic is ruled out by skintests.
VASOMOTOR RHINITISVasomotor rhinitis is also known as post-nasal drip and nasal congestion. A personwith this type of rhinitis may havesymptoms when exsposed to temperatureand humudity changes. Symptoms can alsooccur when exposed to smoke, strongodors, perfumes, or even emotional upsets.All of the above mentioned exposurescause dialation in the blood vesseles in thelining of the nose, which result in swellingand drainage.
INFECTIONOUS RHINITISInfectionous rhinitis can occur as a cold, which mayclear rapidly or continue with symptoms that canlast a week or longer. Some people may devolpean actue or chronic bacterial infection. The mostcommon is the common cold which is 92% of thetime caused by Rhinovirues and Coronavirues.Symptoms not only include runny or stuffy nose butalso sore throat, headache, and cough. Also notedis an increase in colored (not clear as in otherrhinitis) yellowed or greenish thickend nasaldischarge.
HORMONAL RHINITISHormonal rhinitis is often seen with... as the nameimplies, hormonal changes. It often occurs withpregnancy, puberty, hypotyroidism, and themenstral cycle. The most common being pregancyduring the early tri-mester and last 2-3 weeks ofpregnancy. Hormonal rhinitis displayes the samecommon traits as allergenic with a noticed increasein clear nasal fluid discharge. It is not commonlytreated by any medication due the cause beingtriggered by homones and the means to control itwould be to administer an anti-hormone blockerthat would cause an adverse reaction greater thenthe annoyence of the rhinitis.
Pathogen and Virulence factors.Virulence is the degree of pathogenecity or theability of a bacteria/virus to invade a host. Rhinitisis a very common misconception that it in its-self isa pathogen. Its not. It is an outside agent that isbeing dispelled from the body therfore being a signor a symptom and not a classic defenition of apathogen. Rhinitis is the outcome of the bodysability to produce mucous to trapdust, pollen, pollution, bacteria, viruses, etc.. Nasalfluid flows from the front of the nose to the rear ofthe nose and down the throat. When to muchmucous is made then it cause an overflow whichpushes fluid out the front (runny nose).
Epidemiology of RhinitisEpidemiology is the study of health events, healthcharacterics, and health patterns in a population. Rhinitisbeing one the most common misdiagnosed problems andbrushed off as just a cold, leads it to have great problemsunderstanding the epidemiology. It is seen everywheree onthe globe, including outer-space as in 1994 a shutlle missionastronaught had non-allergenic rhinitis after his 5th day beingin outer-space. It has many causes from theweather, pollutions, to simple human sensetivity. Also beingthat in the medical field, rhinitis is seen more as anannoyense then a true problem, most epidemioligist choosenot to study rhinitis but rather a more pressing or urgentmatter.
