Delayed Reaction and Priming

Matt, a thirty year old with a long history of seasonal allergic rhinitis and asthma in the fall, attended his new girlfriends’ family Labor Day picnic. Shortly after arriving, Matt began to develop a runny nose and sneezing. But after being pestered by these symptoms for several hours outdoors, they gradually subsided. When the picnic […]

Delaying Exposure May Delay Allergies

Mary, a 28-year-old schoolteacher with a history of hay fever and atopic dermatitis, is eight months pregnant. Her husband also has had asthma since childhood. They are wondering if there is any way to delay or even prevent their baby from developing allergies. People with atopy have a tendency to develop closely linked allergic disorders […]

Allergen Avoidance Begins at Home

We spend about one third of our lives in our bedroom. And because most of this time is spent in bed, the bedroom is the most important room to be rid of dust mites, pet dander, and molds. One of the most common indoor asthma and allergy triggers are dust mites. Even though you cannot […]

Allergic Rhinitis

Anne, a 28 year old musician, has experienced increased sneezing with a runny and stuffed nose, for more than ten years, particularly worse in the fall. She wonders “Am I allergic to something in the air?” Defined as an “abnormal sensitivity to substances such as pollen, food, medication or insect sting, an allergy is normally […]

Allergic Rhinitis: Histamine and Antihistamine

As we know, allergic reactions involve an interaction amongst IgE, allergens, mast cells or basophils, which release chemical mediators such as histamine, leukotrenes, and prostaglandins to name a few. After being released from mast cells, histamines seek out “receptor” sites located in the nasal lining tissue. Like a key inserted into a lock, the histamine […]

Pollination and Allergy

Pollen, tiny particles that travel in the air or carried by insects, are male cells of flowering plants and essential to plant fertilization. However, if it’s windy while pollination is in progress, there exists a higher tendency of wind-borne-pollen induced allergic conjunctivitis, rhinitis and asthma. In the United States , most wind-pollinating plants, those not […]

Sinusitis: Facts and Remedy

Our sinuses are located within cavities beneath the formation of our cheekbones, called maxillary, behind the forehead and eyebrows, called frontal, on both sides of the bridge of the nose, called ethmoid, and behind the nose, in front of the brain, called sphenoid. Each sinus cavity is joined to an opening into a continuous membrane, […]

Treating Nasal Inflammation

Allergic rhinitis, chronic inflammation of the lining membrane of the nose, is triggered by allergens such as trees, grasses, weeds, dust mites, and animal dander. The interaction between allergens, IgE and our mast cells and basophiles triggers the release of chemical mediators such as histamine, prostaglandins, and leukotrienes to name a few. The first step […]

Urticaria: An Allergic Skin Condition

Have you ever been stung by a bee or wasp or bitten by a mosquito and developed an itchy, red, spongy, raised, flat bump? If so, then you have experienced an “urticaria or hives.” Urticaria (hives) is an outbreak of red bumps or patches called wheals that appear on the skin that are produced by […]
