If you have clergyman's knee, tailor's seat, tennis elbow or trigger finger, what you really have is a form of bursitis or tendinitis, the Arthritis Foundation points out. These and other slang expressions are often used to describe certain types of bursitis or tendinitis which affect structures around different joints. Sudden stress, from a sports injury, for example, or from repeated use of a joint, as on certain jobs, may bring on this condition. However, the exact cause is often unknown.

Over-the-counter painkillers fall into two groups. The first, nonsteroidal anti-inflammatory medications (NSAIDs), includes ibuprofen (often sold as Advil and Motrin), naproxen (sold as Aleve) and aspirin. All three drugs dull pain and fight inflammation. Acetaminophen (often sold as Tylenol) is in a group of its own and targets only pain. Scientists are still working out the details about how these drugs work. NSAIDs are the better understood. In general, this group attacks two types of enzymes that produce prostaglandins, a broad class of chemicals that do a wide variety of jobs throughout our bodies.

If you're drinking bottled tea beverages in order to reap the benefits of polyphenols in tea, you may be wasting your money. A new study shows that at least some bottled beverages that boast of having tea content actually have paltry levels of polyphenols. Polyphenols are antioxidants that are thought to promote health by protecting the body's tissues against oxidative stress and related cell damage that can cause cancer, heart disease and inflammation. A typical cup of brewed black or green tea contains 50 to 150 milligrams of polyphenols.

A new study found that people who'd had coronary bypass surgery were more than three times more likely to be alive 15 years later if they were happily married than if they were not married. A big part of this effect could be due to the positive influence of a supportive spouse, the authors say -- in getting the patient to live better, take meds, get to doctor appointments, etc. Plus marriage could give someone heightened reason and feeling of responsibility to look after themselves.

Eating food containing trans fats and saturated fats could contribute to depression, scientists reported Wednesday. Researchers in Spain followed 12,059 people over six years, analyzing their diets, lifestyles and medical problems. The people who ate the most trans fats, which are commonly found in pastries and fast food, had a 48% increased risk of depression compared with people who did not eat trans fats. Individuals who ate a lot of polyunsaturated fats -- a healthier type of fat that is found in olive oil, for example -- had a lower risk of depression.

Pfizer Inc., the world's biggest drug company, is laying off as many as 800 scientists this year in its latest effort to refocus disappointing research efforts and cut overhead ahead of an expected crash in revenue. Pfizer plans to reduce its global research staff of about 10,000 people by 5% to 8% this year, the company said. The move comes after the New York company announced in September that it was narrowing its research focus to six disease areas -- Alzheimer's, cancer, schizophrenia, pain, inflammation and diabetes.
