Alexander Chong asked:


What is actually allergy rhinitis? Allergy rhinitis is an allergic disease, which is caused by the sensitinogen that reacting on the mucous membranes in the nasal cavity. It has two types; those are perennial and seasonal allergic rhinitis. Perennial allergic rhinitis occurs throughout the year; whereas, seasonal allergic rhinitis usually occurs during the blossoming or flowering season. In this season, plants start to release their pollen for breeding purpose. Pollen is one of the sensitinogens to the allergic rhinitis. Clinical features of allergic rhinitis are; itching in the nose, sneezing, watery nasal discharge and nasal obstruction. There are about 20 % of adults and children have seasonal or perennial allergic rhinitis.

Although it is prevalence in most of the countries regardless tropical or seasonal, most of the conditions are not treated adequately and the consequence is that allergic rhinitis becomes chronic. The chronic state of allergic rhinitis usually will lead to more serious complications of the upper and lower airways such as asthma, sinusitis and otitis media with effusion. Otitis media is an inflammation of the middle ear. Fluid is built up in the middle ear and causes temporary lose of hearing. However, if this chronic disease is not treated properly, it may lead to permanent hearing impairment.

 A few medical scientists had carried out surveys to study the epidemiologic links between allergic rhinitis and other airway diseases. What they had found out were, 78% of patients who had asthma were also had allergic rhinitis. They also found out that 99% of adults and 93% of adolescents, who had allergic asthma, also had allergic rhinitis. Besides, the other study that had been carried out for 23 years was found out that college students who previously had allergic rhinitis had three times higher the possibility to have asthma compared to those students who had not had allergic rhinitis What is actually allergy rhinitis?

Besides, the other study that had been carried out for 23 years was found out that college students who previously had allergic rhinitis had three times higher the possibility to have asthma compared to those students who had not had allergic rhinitis before.

Many researches and works had been carried out to study the epidemiologic link between allergic rhinitis and sinusitis. The results had been well documented. The earlier study showed that 53% of children, who had allergic rhinitis, also had sinusitis. They proved this from the children abnormal sinus radiographs. Whereas, recent study showed that up to 70% of children, who had allergy and chronic rhinitis, had abnormal sinus radiographs. 78% of the patients who had recurrent sinus infection, rhinitis allergy was coming together with their extensive sinus disease. For the children who had otitis media with effusion, 40 to 50% of them had allergic rhinitis. This was confirmed by positive allergy skin tests or increased serum IgE antibodies to specific allergens test.

Scientist had proposed a model for the development of sinusitis and otitis media. Their proposed model assumes that the earliest cause for sinusitis is not bacterial infection but it is due to the obstruction in the nasal cavity, which hinders the normal movement of air and secretions in and out of sinuses. Virus that causes nasal inflammation is upper respiratory tract infection (URTI) type, which is called rhinovirus. Research had been carried out to study the effect of this virus to the nasal diseases. The result showed that when rhinovirus is inoculated into the nasal passage of a group people, one third of these people would develop sinus abnormities and typical sinus disease symptoms. Another study also showed that 87% of healthy adult, who voluntarily went through self-diagnosed colds, had maxillary sinuses illness.

Fluid inside the sinus cavity must be drained normally to keep the nasal healthy. When nasal being infected by bacteria or virus, or exposure to allergen, dust or chemicals, thicken secretion will be developed and it has higher possibility blocks the narrowed sinus ostia (opening that connect to the sinus cavity). Accumulation of these secretions in the sinus cavity will lead to further obstruction, mucosal swelling and also thicken the sinus mucosa. This will create an anaerobic environment that further favorite the bacterial growth and lead to infection. Congested sinus ostia must be resolved if not, it will lead to recurrent acute and eventually chronic nasal disease. This model also explained why chronic sinusitis is resistant to the antimicrobials treatment alone. To treat the sinusitis properly, antihistamines and corticosteroids have to be used as a combination with the antimicrobials treatment.

A similar model had been developed by scientist to explain the occurrence of otitis media with effusion. 83% of the children had at least once occurrence of acute otits media by the time they reach 3 years old. This model hypothesizes that nasal inflammation that is caused by allergens or URTIs virus will further cause inflammatory swelling and obstruction of the Eustachian tube. Obstruction of the Eustachian tube will increase negative pressure in the middle area and without improper ventilation; fluids will accumulate in the middle ear. Obstructed Eustachian tube will open occasionally with an effusion and this will **** the inner nasal secretion, which contain bacteria, virus and allergens into the middle ear cavity. Consequently, this will cause acute bacterial otitis media.

From the information above that have been gathered from various scientific publications, we know that common nasal allergy should not be left untreated. This is because it will lead to obstruction, fluid accumulation, bacterial infection and acute disease. If these diseases are not treated properly or successfully, a chronic state of inflammation, nasal congestion, and sinus infection will be developed. And it can further cause mucosal damage and ultimately, chronic disease. If the disease spreads to the middle ear, it will cause permanent hearing impairment

 



Detailed Information on Nasal Polyposis

Juliet Cohen asked:


Nasal polyps are the most common tumors of the nasal cavity. Nasal polyposis can impair a person’s quality of life more than perennial allergic rhinitis. Nasal polyps are soft, jelly-like overgrowths of the lining of the sinuses. They look like grapes on the end of a stalk. Large polyps can bloc the nose and increase the risk of sinusitis. They may be yellowish, grey or pink in colour. They are common and are not cancerous. Nasal polyposis results from chronic inflammation of the nasal and sinus mucous membranes. Chronic inflammation causes a reactive hyperplasia of the intranasal mucosal membrane, which results in the formation of polyps.

Nasal polyps can vary significantly in size. There may be only one but sometimes several develop like a ’small bunch of grapes’ on a stem. Polyps usually affect both nostrils. Nasal polyps can vary greatly in size. There may be only one but sometimes several grow like a ’small bunch of grapes’ on a stem. The cause of the inflammation is certain conditions make nose inflammation and polyps more likely. These include: asthma, allergy to aspirin, cystic fibrosis, and some rare conditions of the nose. Nasal polyps can occur along with many other respiratory diseases, such as allergic rhinitis, chronic sinusitis, asthma, and aspirin allergy.

Nasal polyps also occur in a majority of people with Churg-Strauss syndrome, a rare disease that inflames the blood vessels (vasculitis). Nasal polyps occur in around 1 in 200 people. It appears that nasal polyps are more common in people with non-allergic rhinitis and non-allergic asthma, rather than allergic types of these conditions. Nasal polyps can affect anyone. However, most cases occur in people over the age of 40 years. They are four times more common in men than in women. In general, women are more likely to have nasal polyps than are men. Nasal polyps are uncommon in children.

Medications are the most common treatment for nasal polyps. Surgery may be needed to eliminate larger growths. Topical nasal steroid sprays, such as Flonase and Nasonex, can help decrease the size of nasal polyps and prevent polyps from growing back after surgery. Use allergy shots in an attempt to treat or stop nasal polyps from growing back after surgery. Intranasal corticosteroid sprays reduce the growth of small intranasal polyps are most effective in the postoperative period. Prevention is better than cure. Avoid over-the-counter saline sprays that contain additives, such as benzalkonium, which can actually inflame the mucous lining of your nose.



How to Take Good Care of your Nose?

Alexander Chong asked:


A patient once had asked to a doctor about what did he need to do to take good care of his nose. The doctor simply and straightforwardly replied to the patient that what was more important was what not to do to your nose. Bad habits such as nose-picking, sniffing, rubbing, blowing the noses hard or stuffing things such as tissue and handkerchiefs up to the nostril can do a lot of harm to your nose. Generally, nose will take good care by itself. Physiologically, when we breathe in air in our lung, nose will warm, clean and humidify it. When we breathe out the air from our lung, it will cool and remove the water from the air. Besides using for breathing, nose is also the organ of smell and allows us to speech with a quality voice. Anatomically, a layer of skin covers the external part of the nose. Appearance of the nose is maintained by a complex network of bone and cartilage. Its function and shape may be altered if its complex network of bone and cartilage has been damaged by either trauma or infection.

Internal part of the nose contains respiratory mucous membranes, paranasal sinuses, nasolacrimal duct and nasopharynx. Besides all these sinuses, internal part of the nose also contains gland that secreting mucous. Tiny-hair-like-cilia continuously pushes the secreted mucous backwards into the back of our nose and throat, in order that, mucus does not flow out from our nostrils. Septum is the partition in the middle part of the internal nose. It is a cartilage, which can be easily fractured. Some people septum has deviated after born and some deviation may due to the unperceived injury during childhood. This will cause blockage on one side of the nose. However, this deviation can be corrected by an operation.

Contents of mucus are merely a mixture of water, ions, glycoproteins and immunoglobulins. Mucus can be said as part of the nasal defense system and it keeps the nose clean and free from bacteria, fungus and viruses. At the roof of the nose, there is olfactory mucosa, which is responsible for our sense of smell. Located at the side and top of the nasal cavity are the air sacs paranasal sinuses. There are total four pairs of paranasal sinuses and given name as maxillary, ethmoid, frontal and sphenoid sinuses. This is where the mucous has been produced and being drained out through the openings called ostium. Infection that causes obstruction to this mucous outflow can lead to sinusitis. Conditions that directly and indirectly affect the nose are common colds, allergic rhinitis, sinusitis and nasal polyps.

Common cold is a very common disease that everybody can suffer at one time or another. It is caused by an infection of self-limiting viral. The symptoms are production of excessive clear mucous (runny nose), sneezing and nasal congestion. Seriousness of this disease is depending to how strong our immune system and also how vigorous the viruses that attack us. If we have a strong immune system, this disease will not exacerbate to sinusitis, asthma and Otitis Media with Effusion (OME). People with weak immune system will suffer a lot more. This is because it not only causes runny nose but also causes inflammation in the nasal passages and sore throat. If this disease does not treat within a few days for the one who does not have a strong immune system, it can exacerbate to sinusitis, asthma and Otitis Media with Effusion (OME). This disease can easily spread through body to body close contact especially hand to hand contact, sneezing mucous and saliva droplets. To recover from this disease, infected person only needs to keep warm, rest and take a lot of warm water. According to most of the resources, there is no cure for common cold. However, doctor usually prescribes antibiotic, anti-fever drug and anti-cough syrup to the patience. Most of the medical doctor will also include a few supplements such as vitamin C, zinc and Echinacea. Prescribed antibiotic by the doctor is not for treating the common cold virus. This is because antibiotic is not capable to kill virus. However, it can kill bacteria that take advantage during the infection of cold viruses.

Allergic rhinitis is also known as sensitive nose. Symptoms of this disease are continuous sneezing, nasal congestion and runny nose. The symptoms emerge only when one has been exposed to certain allergens such as house dust-mite, pollen, fungi, cigarette smoke, animal dandruff, furs and other irritating volatile chemicals. Sufferer can take anti-histamine tablets to relieve from this disease. Histamine is the main chemical that causes sensitive feeling in the nasal cavity. Nasal sprays contains corticosteroid hormone, which helps reduce our body immune system sensitivity to the foreign antigen, also can help to relieve the sensitive feeling in the nasal cavity. Corticosteroid is one of hormone that has been secreted from our adrenalin gland. Besides all these, immunotherapy is also one of the ways that can be used to treat this disease. These symptoms also can be alleviated by having regular exercise

Sinusitis is caused by the infection of the bacteria and fungi to the paranasal sinuses. This happens when bacteria and fungi entering these cavities. Occurrence of sinusitis is due to inflammation, nasal polyps and other nasal anatomical abnormalities that obstruct the mucosal outflow. Patient with sinusitis usually feels pain or pressure at the forehead or face. It is quite common that yellowish and greenish mucous will be discharged from your nostril especially in the morning. One with sinusitis, sense of smell will reduce or not that sharp compared to healthy nose. Sinusitis is due to the bacteria and fungi infection, so, antibiotics can help. However, prolonged and frequent sufferers may need to go through operation to clean up the nasal sinuses.

Nasal polyps are a grape-like swellings found in nasal cavity. They tend to block the air to flow through the nasal passage when breathing. Usually, it will cause production of excessive mucous. Sometimes, it will obstruct the ostium of the paranasal sinuses and cause the nasal mucous cannot be flowed out easily from the paranasal sinuses. This will give rise to sinusitis. Nasal sprays can control nasal polyps. Some nasal sprays can make the nasal polyps shrank temporarily. However, prolonged use will cause the nasal polyps rebound and become bigger. But if the nasal polyps are big and multiple and cause obstruction in the nasal cavity, operation is required to remove them. Unfortunately, they are a recurring disease.
