17 Laboratory Tests Nasal Smear. The doctor may take a nasal smear. The nasal secretion is examined microscopically for factors that might indicate a cause, such as increased numbers of white blood cells, indicating infection, or high counts of eosinophils. High eosinophil counts indicate an allergic condition, but low counts do not rule out allergic rhinitis. Tests for IgE. Blood tests for IgE immunoglobulin production may also be performed. One test is called the radioallergosorbent Test (RAST), used to detect increased levels of allergen-specific IgE in response to particular allergens. Blood tests for IgE may be less accurate than skin tests. They should be performed only on patients who cannot undergo skin testing or when skin test results are uncertain.

18 Imaging Tests In people with chronic rhinitis, the doctor may also check for sinusitis. Imaging tests may be useful if other tests are ambiguous. CT scans may be useful for some cases of suspected sinusitis or sinus polyps.

20 TIPE ALLERGIC RHINITIS
Seasonal (hay fever) Perennial (intermittent or persistent) Occurs in response to specific allergens (pollen from tree, grasses, & weeds) present at predictable times of the year and typically cause more acute symptoms Occurs year round in response to nonseasonal allergens (e.g.,dust mites, animal dander, molds) and usually causes more subtle, chronic symptoms.

21 SEASONAL ALLERGIC RHINITIS
Symptoms of Seasonal Allergic Rhinitis : Runny nose; congestion; sneezing Itching of the eyes, throat, nose, or roof of the mouth Watering or redness of the eyes Macam2 alergen, seperti: grass pollens, tree pollens, fungal mould spores. grass pollens tree pollens fungal mould spores Perennial

26 House dust mite Dust mites favour homes with high humidity levels and constant warm temperatures, and under these conditions mite populations explode, although there are some seasonal fluctuations. The mites are known to concentrate in high traffic areas in homes and on certain furniture items, especially beds, upholstered lounges, chairs, and in carpets with long fibres. They are attracted to these areas for food, and they feed on shed human skin scales and secretions, house dust, fungal spores, pollen grains, plant fibres, and insect scales. Dust mites dislike strong light and will take harbourage in the seams, ledges, and framework of furniture when exposed. Due to their light weight, dust mites can become airborne during activities such as bed making, and in this way can be distributed throughout the room or house.

It has two distinct meanings, referring both to the usual state preceding falling asleep, and the chronic condition referring to being in that state independent of a circadian rhythm. The disorder characterized by the latter condition is most commonly associated with users of prescription hypnotics, such as mirtazapine or zolpidem.e times. Tx

49 TIPS... Do not keep pets such as dog and cat at home. If you already have one and cannot give it away, try to avoid close contact. Keep it away from the living room and bedroom. Avoid fuzzy or furry toys or clothing. Do not carpet the floor. Change the linen and pillow case frequently (twice a week) and wash them in hot water (>60 degree Celsius). There are also special anti-dust mite cover for the mattress and pillow available commercially. Keep the house dry, clean and adequately ventilated. Clean the curtain and upholstery frequently. Avoid prolonged stay in dusty and polluted areas.

59 Indoor Protection against Allergens
1. Controlling Pets People who already have pets and are not allergic to them are probably at low risk for developing such allergies later on. When children are exposed to more than one dog or cat during their first year, they have a much lower risk for not only pet allergies but also seasonal allergies and asthma. (Pet exposure does not protect them from other allergens, notably dust mites and cockroaches). For children who have an existing allergy to pets: If possible, pets should be given away or kept outside. If this isn't possible, they should at least be confined to carpet-free areas outside the bedroom. Cats harbor significant allergens, which can even be carried on clothing. Dogs usually present fewer problems. Washing animals once a week can reduce allergens. Dry shampoos, such as Allerpet, that remove allergens from skin and fur and are now available for both cats and dogs and are easier to use than wet shampoos.

60 Indoor Protection against Allergens (Lanjt..)
Preventing Exposure to Cigarette and Cooking Smoke Parents who smoke should quit. Studies show that exposure to second-hand smoke in the home increases the risk for asthma and asthma-related emergency room visits in children. 3. Controlling Dust Spray furniture polish is very effective for reducing both dust and allergens. Air cleaners, filters for air conditioners, and vacuum cleaners with High Efficiency Particulate Air (HEPA) filters can help remove particles and small allergens found indoors. Neither vacuuming nor the use of anti-mite carpet shampoo, however, is effective in removing mites in house dust. Vacuuming actually stirs up both mites and cat allergens. People with these types of allergies should avoid having carpets or rugs in their homes. For children with allergies, vacuuming should be performed when the child is not around.

61 Indoor Protection against Allergens (Lanjt..)
4. Bedding and Curtains Replace curtains with shades or blinds, and wash bedding using the highest temperature setting. Encase mattress and pillow in special dust mite proof covers (however, washing is very important since impermeable covers alone do not help prevent allergies). Wash pillow in water hotter than 150 F, or in cooler water with detergent and bleach. Wash sheets in blankets weekly and hot water. Avoid sleeping or lying on cushions or furniture that is cloth covered. Stuffed toys should be kept away from the bed and washed weekly as described above. Placing toys in a dryer or freezer may help but is not considered enough. Children should sleep as high off the floor as possible (avoid the bottom bunk of a bunk bed).

62 Indoor Protection against Allergens (Lanjt..)
5. Reducing Humidity in the House Living in a damp environment is counterproductive. Humidity levels should not exceed %. Fix all leaky faucets and pipes, and eliminate collections of water around the outside of the house. Dehumidify basements, but empty and clean humidifier daily with a vinegar solution. Clean often any moldy surfaces in basement or in other areas of the home. 6. Exterminating Pests (Cockroaches and Mice) Use professional exterminators to eliminate cockroaches. (One study reported that ridding a home of cockroaches and cleaning the house using standard housecleaning techniques failed to eliminate the cockroach allergens themselves.) Exterminate mice and attempt to remove all dust, which might contain mouse urine and dander. Keep food and garbage in closed containers. Keep food out of bedrooms.

63 Outdoor Protection against Allergens
The following are some recommendations for avoiding allergens outside: Start taking allergy medications weeks before ragweed season begins. Be sure to take allergy medications before going outside. If regular medications do not work, ask your doctor about allergy shots. Camping and hiking trips should not be scheduled during times of high pollen count (May and June for grass pollen and September to October for ragweed). Patients who are allergic should avoid barns, hay, raking leaves, and mowing grass. (A mask can be worn during outdoor chores to help reduce pollen exposure.) Sunglasses can help prevent pollen from getting into eyes. After being outdoors, clean off pollen residue by bathing, washing hair and clothes, and using a nasal salt water rinse.

64 Dietary Factors Some evidence suggests that people with allergic rhinitis and asthma may benefit from a diet rich in omega-3 fatty acids (found in fish, almonds, walnuts, pumpkin, and flax seeds) and fruits and vegetables (at least five servings a day). Some studies also suggest reducing sodium, trans fatty acids (hydrogenated fats found in commercial products and baked goods), and omega-6 fatty acids (found in most vegetable oils). Investigators are also studying probiotics -- so-called good bacteria, such as lactobacillus and bifidobacterium, which can be obtained in supplements.

65 LAMA PENGOBATAN Perbaikan gejala seharusnya terjadi dalam beberapa hari. Jika tidak ada perbaikan setelah 5 hari → rujuk ke dokter Outline Dokter !!

66 Saat untuk merujuk ke dokter
Wheezing & shortness of breath Tightness of chest Painful ear Painful sinuses Purulent conjungtivitis Failed medication Nasal polyps occur in some people with perennial rhinitis; they are smooth, round, soft structures attached to the lining of the nose. They can cause obstruction of the nose, and loss of smell. Occasionally they need to be surgically removed due to extreme discomfort. Over time, people with perennial rhinitis may experience a reduced sense of smell, headaches, and recurrent infections. Other potential complications include infections of the middle ear and sinuses. Outline Thanx

67 Purulent conjungtivitis
any inflammatory process that involves the conjunctiva; however, to most patients, conjunctivitis (often called pink eye) is a diagnosis in its own right. Most causes of conjunctivitis are benign, and the role of the emergency physician is to separate those few conditions requiring more vigorous treatment from the majority that can be handled satisfactorily in the ED. Purulent conjungtivitis

68 Allergic Rhinoconjunctivitis
The presence of ocular itching, tearing, or redness and/or the presence of nasal itching, persistent rhinorrhea, nasal obstruction, or sneezing. There may be an identifiable season of the year or a particular exposure which will elicit symptoms. Symptoms should exceed 6 weeks or be present in a particular season at least 2 years in a row.
