Get Out of Bed and Stay ACTIVE

Rest has been standard recommendation for low back pain (LBP) for years, especially within the medical community. This recommendation persists despite research evidence (see "Sciatica: Bed Rest vs. Watchful Waiting" in the April 1999 issue of To Your Health) suggesting that prolonged rest serves no purpose and may delay return to work and resumption of normal activities.

This report from the International Paris Task Force on Back Pain outlines the role of activity in the treatment of back pain. In addition to presenting numerous recommendations and summaries, the authors offer the following key points as summary to their findings:

* Bed rest is contraindicated in subacute and chronic cases of LBP.

* In acute cases, bed rest should neither be enforced nor prescribed.

* If authorized (based on pain indication), bed rest should be for the shortest duration possible.

* Patients whose pain is intense enough to justify bed rest should be referred for a specialized back pain evaluation if daily activities have not been resumed after 10 days of strict bed rest (defined as getting up only to go to the bathroom) and adequate pain therapy.

Are you suffering from low back pain? If you think bed rest is the solution to your pain, think again. As the authors note (see above), if your pain is intense enough to justify bed rest, schedule a "specialized back pain evaluation" with an expert in managing and resolving back pain -- your doctor of chiropractic!

DTP, Tetanus Vaccinations Cause Allergy Symptoms?

Infants and young children have been routinely vaccinated against diptheria, tetanus and pertussis since the late 1940s. Such vaccination practices have reduced the incidence of disease, although they have not come without a price.

A case in point comes from a recent study published in the Journal of Manipulative and Physiological Therapeutics. Data from the Third National Health and nutrition Examination Survey (1988-1994) provided information on diptheria-tetanus-pertussis (DTP) or tetanus vaccination, allergy history, and allergy symptoms in 13,944 children (two months to 16 years old).

Results showed that vaccinated children were twice as likely to have a history of asthma, and 63% more likely to suffer an allergy-related symptom in the previous 12 months, compared with unvaccinated children. These associations were particularly strong in younger children (5-10 years of age).

The authors conclude that the number of allergies or allergy-related conditions attributable to vaccination may be high, as nearly all children in the United States receive at least one dose of DTP vaccine. Considering that chronic sinusitis, asthma and allergic rhinitis account for nearly 10 million care visits annually among children 15 and younger, parents should consult with their doctor to discuss the potential benefits and risks of vaccination.

weight Training: Is One Set Enough?

The physiological benefits of resistance training include increased strength, muscle size, lean body mass, bone mass, and overall physical function. Millions of Americans spend a number of hours each week at the local gym or health club, grinding out set after set in the quest for lifelong health and fitness.

The American College of Sports Medicine and the Surgeon General recommend a weight-training program requiring a minimum of one set of 8-12 repetitions for each muscle trained per exercise, and some research suggests that multiple sets may maximize the physical benefits. However, a recent study in Medicine & Science and Sports & Exercise adds to the mounting evidence that one set per exercise may be just as effective as two or more sets.

Forty-two recreational weightlifters (20-50 years old, averaging 6.2 years of previous training) were divided into two groups and participated in a nine-exercise resistance training circuit. Group 1 performed one set of 8-12 repetitions for each of the nine exercises; Group 2 performed three sets under the same conditions. No significant differences were noted between the two groups after 13 weeks of training, with both groups improving significantly in terms of muscular endurance, one-repetition maximum strength, lean body mass, and overall body composition.

Your doctor of chiropractic can evaluate your current exercise regimen and outline nutritional and exercise guidelines suitable to your needs.

vitamin C Lowers Women's Risk of Gallbladder Disease

The gallbladder's most important function is to store bile, a substance manufactured in the liver which helps the body digest fatty foods. Cholesterol is a normal component of bile; if too much cholesterol accumulates in the gallbladder, gallstones eventually result.

Because estrogen is an important risk factor for gallstone formation (it increases the concentration of cholesterol in bile), women are at particular risk for the disease. Experimental animal studies suggest that ascorbic acid (vitamin C) may play a role in preventing gallstones, an observation that led to a recent study published in the Archives of Internal Medicine.

As part of the Third National Health and nutrition Examination Survey, 7,042 women and 6,088 men provided data on vitamin C intake and the incidence of gallbladder disease. Results showed that increasing serum levels of ascorbic acid were related to a reduced risk for clinical and asymptomatic gallbladder disease in women, but not in men. Specifically, each standard increment increase in ascorbic acid level reduced the risk of a woman getting the disease by 13%.

Your chiropractor can provide you with more information on these results and suggest nutritional guidelines appropriate to your needs.

NSAIDs May Contribute to Congestive Heart Failure

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed for migraines, sprains, strains, and countless other conditions in which pain and/or inflammation result. NSAIDs have come under fire in recent years, with mounting evidence suggesting possible dangerous side effects associated with their use.

One of the most severe potential side effects may be congestive heart failure (CHF) in susceptible patients, according to a study in the March 27, 2000 issue of the Archives of Internal Medicine. Patients admitted to hospitals with a primary diagnosis of CHF (365 cases) were compared with patients without CHF (658 cases) admitted to the same hospitals for other conditions. Patients were interviewed to gather data on recent use of aspirin and other NSAIDs.

Results: Use of NSAIDs in previous week doubled the risk of hospital admission for CHF. Additionally, patients who reported taking higher levels of NSAIDs in the previous week were more likely to be admitted for CHF than patients taking lower levels.

Why this relationship exists is unknown, although the authors speculate that possible drug interactions (NSAIDs and other drugs used by heart patients) may contribute to the problem. They emphasize that "NSAIDs should be used with caution in patients with a history of cardiovascular disease." Talk to your doctor about the potential dangers of NSAIDs and other commonly prescribed drugs.

Olive Oil Helps Prevent Colon Cancer?

According to mythology, the olive tree was brought to Greece from the goddess Athena. Olive oil has long been considered a symbol of excellence and purity, and increasing evidence points to its value in maintaining a healthy lifestyle and preventing disease.

Precisely this type of evidence appeared in a recent issue of the journal Gut, which published a study espousing the benefits of olive oil in preventing colon cancer. Rats were randomly assigned to receive a diet rich in one of three types of fatty acids found in oil (safflower oil, olive oil, fish oil). After one week receiving a 5% fat diet, each dietary group was redivided, with half of the animals receiving a cancer-causing agent and half receiving harmless saline.

Rats fed a diet supplemented with olive oil had a lower risk of colon cancer than those fed diets supplemented with safflower oil -- nearly as low as those supplemented with fish oil (an established colon cancer-fighting agent).

These findings add to the considerable evidence linking good nutrition with health promotion and disease prevention. Your chiropractor can provide you with more information on the value of nutrition in fighting disease, and help you develop a comprehensive wellness program for you and your family.

Never Too Late to Start Exercising

No doubt you've heard about the many documented benefits of physical activity: decreased incidence of disease and increased vitality and wellness. Are you participating in a consistent exercise routine? If you're not, it's never too late to start.

Consider a study that appeared in the British Journal of Sports Medicine last year which examined the potential relationship between balance and postural control deficits and the incidence of falls. Specifically, the authors sought to determine whether it is of value for the elderly to start physical and sporting activities (PSA).

Sixty five men and women (aged 60-85) were divided into four groups based on reported levels of PSA (always practiced; never practiced; lately begun; or stopped at an early age), and a series of posture tests provided information on overall balance control and other variables.

Consistent participation in physical and sporting activities optimized balance control. Subjects who never practiced PSA had the worst balance control; subjects who always practiced PSA had the best control. Most interesting perhaps was the observation that subjects who had begun PSA late in life had nearly the same postural control as those who had always practiced PSA.

As the authors suggest in their conclusion, "...PSA are extremely useful for elderly people even if it has not been a lifelong habit." These findings are particularly important, as accidental falls are the primary cause of death among the elderly population. Whatever your age, take advantage of the many benefits of consistent physical activity. For more information, contact your chiropractor.

Arthritis Sufferers: Get the Facts on Chondroitin Sulfate

Thin, brittle bones can break without warning - one of the most distressing complications associated with arthritis. There are more than 100 different types of arthritis. The common misconception holds that the disease only affects the elderly, but millions of young people, including children, are also affected.

Previous research suggests that exercise (see "Maintain Strong Bones with Exercise" in the Sept. 1999 To Your Health), and nutritional factors (see "Magnesium Helps Prevent Bone Breakdown," Nov. 1998 TYH) can help fight arthritis by improving bone strength. Further evidence of this potential nutritional role comes from the Journal of Rheumatology, which published a study evaluating the utility of chondroitin sulfate (CS) in the management of osteoarthritis.

Chondroitin sulfate is the substance that gives cartilage (the spongy portion of bone) its elasticity and fluidity, suggesting its potential usefulness in influencing bone strength. This study reviewed previous controlled trials of CS in the treatment of hip and knee osteoarthritis (OA), finding that:

* In seven reviewed trials, reported pain was only 57% of original baseline scores in groups taking CS; and

* Patients taking CS reported reductions in consumption of nonsteroidal anti-inflammatories (NSAIDs) and/or analgesics compared to baseline.

The authors emphasize that their results require additional support, but note that "There is evidence that chondroitin sulfate can reduce pain and improve function in patients suffering from osteoarthritis." If you or someone you know suffers from arthritis, talk to your doctor about the potential benefits of chondroitin sulfate.
