Diverticular disease of the colon

Diverticular disease develops due to a lack of dietary fiber, and is most common in the elderly, but many people never realize they have it because there are few symptoms.

Rhabdomyosarcoma

Sarcomas are a type of cancer that develops from the soft tissues (fleshy parts) of the body, as well as from bone and fatty tissue. This type of cancer is different from carcinomas. Carcinomas develop more frequently in the body's organs, especially those organs that contain glands. Examples of carcinomas include lung cancer, colon cancer, pancreatic cancer, breast cancer, prostate cancer.

Rhabdomyosarcoma is a cancer that forms in the skeletal muscles. Skeletal muscles attach to bones. They help the body move. Most rhabdomyosarcomas occur in children and teenagers.

Will there be a COVID-19 vaccine?

Ask the doctor

Q. Will we have a vaccine to prevent COVID-19 and, if so, when?

A. I'm optimistic because never in human history has so much scientific time and effort been spent trying to make a vaccine. But it won't it be easy. As fast as possible, the vaccine scientists need to prove, first, that a vaccine is safe (minimal side effects) and, second, that it works to reduce a person's risk of getting the disease. Then they need to produce enough of it to immunize most of the 7.6 billion people on earth. Doing all of this within two to three years of a new virus being discovered would be an unprecedented achievement.

Aspirin linked to fewer digestive tract cancers

In the journals

Scientists continue to explore the health benefits versus risks of aspirin therapy. One new analysis suggests that taking aspirin may protect against several types of digestive tract cancers. The results were published online April 1, 2020, by Annals of Oncology.

Researchers examined 113 observational studies of cancer in the general population. They found that individuals who took aspirin regularly — at least one or two tablets a week — had significantly lower rates of cancers of the bowel, stomach, gallbladder, esophagus, pancreas, and liver, compared with people who did not take aspirin.

Eczema is associated with a higher risk of bone breaks

Research we're watching

If you suffer from the common skin condition eczema, you may have a higher risk of breaking a bone compared with someone who doesn't have the condition, according to a study published in the February 2020 issue of The Journal of Allergy and Clinical Immunology. The study authors found that the 500,000 people in the study who had eczema, which causes itchy dry patches on the skin, were 7% to 18% more likely to break a bone in the wrist, hip, pelvis, or spine when compared with more than 2.5 million participants who didn't have the condition. Researchers said it's not clear if this elevated fracture risk was related to the eczema itself or whether other factors caused the association. For example, the increase in risk could have been related to medications people took to treat eczema. Even so, if you have eczema, the study authors say it may be worth asking your doctor whether you might be at increased risk for osteoporosis.

Avoiding atrial fibrillation

How maintaining a healthy weight and other lifestyle habits can help prevent this common heart rhythm disorder.

During a bout of atrial fibrillation, your heart may beat so rapidly, it may feel as though it's going to explode out of your chest. Commonly known as afib, this heart rhythm problem can leave you breathless and lightheaded—or cause no symptoms at all. About 9% of people ages 65 and older have afib, which raises the risk of stroke and other heart-related problems. But there are ways to lower your odds of developing afib—or to reduce its impact if you already have the condition.

Lessen your load

By far, the most important step you can take is to attain and stay at a healthy weight. "We have good evidence from multiple studies showing that people who are overweight have a higher risk of afib than people who are at a healthy weight," says Harvard professor of medicine Dr. Christine Albert, former director of the Center for Arrhythmia Prevention at Brigham and Women's Hospital. And the more you weigh, the higher your risk: people who are overweight have a 20% to 25% higher risk, whereas those who are obese (a body mass index, or BMI, of 30 or higher) have a 60% higher risk.

What to do about tennis elbow

Tennis elbow is the common term for lateral epicondylitis, an inflammatory condition of the tendon that connects the extensor muscles of the lower arm to a bony prominence on the outside of the elbow called the lateral epicondyle. The condition causes pain at the point where the tendon attaches to the epicondyle. The pain may radiate to the forearm and wrist, and in severe cases, grip strength may lessen. It can become difficult to perform simple actions like lifting a cup, turning a key, or shaking hands.

As many as half of all people who play racket sports have the condition, but most people who have tennis elbow didn't acquire it by playing tennis, squash, or racquetball. It can result from any activity that involves twisting or gripping motions in which the forearm muscles are repeatedly contracted against resistance, such as pruning bushes or pulling weeds, using a screwdriver, or playing a violin. Tennis elbow is an occupational hazard for professional gardeners, dentists, and carpenters.
