Spring Means Sinusitis
Johns Hopkins University
By Howard Levy, M.D.

This time of year is a common time for sinusitis, which simply means inflammation of the sinuses. Let's take a look at the causes of these bothersome symptoms:
Pain and Pressure
The inflammation causes mucus to build up in the sinus cavities behind the cheeks and forehead, causing pain and pressure in the face and head.

Sneezing
When some of the mucus runs down the nose, it triggers sneezing.

Coughing
When mucus drips down the back of the throat into the lungs and upper airway, it causes the coughing.

Sore Throat
The sore throat is due to post-nasal drip. The mucus tends to accumulate in the back of the throat while we're sleeping overnight, so the sore throat is often worse first thing in the morning.

Patients often ask for or expect to be prescribed antibiotics for sinusitis. However, the most common cause is allergy, not infection, so antibiotics are often not the best choice.

Allergy symptoms can occur year-round (perennial) or just during the times when certain triggers are present in the environment (seasonal). The timing, frequency, duration and severity of allergic sinusitis vary from one person to the next, and can change over time.

Allergies are immune reactions to something in the environment. For allergic sinusitis, it is typically something in the air. Pollens (from grasses, trees and other plants), animal dander, and molds are some of the more common allergic triggers, but there are hundreds of possible causes.

Allergy can develop at any time in life - with the very first exposure, after thousands of exposures, or any time in between. So even if you've never been diagnosed with allergy before, it is always something to consider if you have sinusitis.]]>

A new study shows drinking apple juice may improve memory by preventing the decline of an essential neurotransmitter known as acetylcholine.

Neurotransmitters are chemicals released by nerve cells to transmit messages to other nerve cells. They are critical for good memory and brain health.

Previous studies have shown that increasing the amount of acetylcholine in the brain can slow the mental decline found in people with Alzheimer's disease Alzheimer's disease.

"The findings of the present study show that consumption of antioxidant-rich foods such as apples and apple juice can help reduce problems associated with memory loss," says researcher Thomas Shea, PhD, director of the Center for Cellular Neurobiology & Neurodegeneration Research at the University of Massachusetts Lowell, in a news release.

Prior research has shown that supplementing animal diets with other antioxidant-rich fruits and vegetables, such as blueberries, spinach, and strawberries, can help slow age-related mental decline better than using dietary supplements containing purified forms of antioxidants.
Apples for Alzheimer's?

In the study, researchers compared normal adult mice, normal "aged" mice, and special mice that were a genetic model for human Alzheimer's.

The mice were given either a normal diet, or a diet lacking in essential nutrients, for one month. Some of the mice on the nutrient-poor diet were also given apple juice concentrate mixed in their water.

The results showed that normal adult mice and the genetically-engineered mice on normal diets had the same acetylcholine levels.

In fact, the normal adults had the same acetylcholine levels regardless of diet.

However, the genetically engineered mice on the nutrient-poor diet had lower acetylcholine levels. But this drop was prevented in those given apple juice.

In the aged mice on a normal diet, acetylcholine levels were lower than in the normal adult mice; and their levels were even lower if placed on the nutrient-poor diet. But, again, this decline was prevented by the addition of apple juice to drink.

The mice were also put through maze memory tests. "It was surprising how the animals on the apple-enhanced diets actually did a superior job on the maze tests than those not on the supplemented diet," says Shea.

The amount of apple juice the mice drank was comparable to drinking about two 8-ounce glasses of apple juice or eating two to three apples a day for humans.

Human studies looking at apple consumption are coming in the future.

The study was funded by an unrestricted grant from the U.S. Apple Association and the Apple Products Research & Education Council.

Apple to fight Alzhemier's
Drinking apple juice helped mice deliver above average performances in maze trials, which maintained the same level of mental fitness that was otherwise observed as these mice aged.

Thomas B. Shea, of the Centre for Cellular Neurobiology, University of Massachusetts, and his team showed that mice receiving human equivalent of two glasses of apple juice daily for a month produced less of "beta-amyloid," responsible for forming plaques, commonly found in Alzheimer's disease, said a Massachusetts release.

Shea commented that "these findings provide further evidence linking nutritional and genetic risk factors for age-related neuro degeneration and suggest that regular consumption of apple juice not only can help to keep one's mind functioning at its best, but may also be able to delay key aspects of Alzheimer's disease and augment therapeutic approaches."

The study was published in the January issue of the Journal of Alzheimer's Disease.
