Recent strides in allergy treatment aim to get severe allergy sufferers up and moving with new pill and liquid (oral drop) treatments. If approved, these allergy drugs could work more effectively than and eventually replace traditional allergy shots.

Allergies and hay fever can cause allergy sufferers serious discomfort. In addition to a runny nose and nasal congestion, hay fever can cause sinus pressure, itchy eyes and dark circles under the eyes called allergic shiners. Severe hay fever also can cause sleep issues and sinus infections (sinusitis), and may worsen asthma problems.

Some allergy sufferers rely on injections to address these severe symptoms, especially in the spring and fall when allergies and hay fever peak. Shots are given frequently—as often as twice weekly to twice monthly—for several years to build a tolerance to allergens. This therapy is now available orally in pill or drop form, known as sublingual immunotherapy.

Immunotherapy can cut symptoms by 20-30 percent, slightly higher than the use of nasal sprays (17 percent) and daily antihistamines (12-15 percent). Although immunotherapy drops and tablets have not yet made their way to the United States, they are already being used in Europe. Researchers are still investigating the long-term effectiveness of sublingual immunotherapy. One such investigation appears in the Journal of Allergy and Clinical Immunology.

Do you suffer from recurring sinus problems? If so, a friend's cigarette could be to blame. Two out of five cases of chronic sinusitis may be due to exposure to secondhand smoke.

Sinusitis occurs when the sinuses become swollen or infected. According to Mayo Clinic, sinusitis is usually the result of a cold, allergies or other nasal problems, and can easily be treated with antibiotics, heat (to relieve sinus pressure) or a variety of over-the counter medications.

When the condition persists for more than eight weeks or recurs frequently, this is known as chronic sinusitis. Secondhand smoke contains over 50 known carcinogens; these chemicals can also cause heart problems, asthma attacks and nasal irritation.

Researchers from the Henry Ford Health System in Detroit, recruited 612 non-smokers to participate in a study investigating the relationship of secondhand smoke (SHS) and its source to chronic sinusitis. All had been exposed to SHS for five years prior to the study, and half had been diagnosed with chronic sinusitis (CRS).

Researchers focused on four locations where participants were primarily exposed—home, work, public places and social functions. All showed a marked relationship between secondhand smoke exposure and incidence of chronic sinusitis, especially at social functions (51 percent) and in public places (90 percent).

Although levels of exposure were significantly lower for nonsmokers who had not been diagnosed with chronic sinusitis, study co-author Amanda Holm, MPH, says even modest levels of exposure carry risk.

"The poisons found in secondhand smoke are quite an irritant to the sinus and nasal passages and are a major contributor to the development of rhinosinusitis," Holm said in a press release. “"Our findings reaffirm the health hazards of secondhand smoke."
