Different types of nail polish can have varying effects on fingernails, and have pros and cons depending on the chemicals used in making them.

Over the past decade, research has revealed that the majority of patients treated for cancer experience difficulties with memory, attention, concentration, and thinking. There are several lifestyle actions that can help improve these symptoms, as well as certain medications.

Screening symptom-free adults for pancreatic cancer doesn't appear to reduce deaths from the disease, according to a new analysis by the U.S. Preventive Services Task Force (USPSTF). The group advises against recommending screening in this group.

Pancreatic cancer is relatively uncommon, but the prognosis for people who get it is often poor, because it is frequently found at an advanced stage. This has made it the third most common cause of deaths from cancer in the United States. It was hoped that screening for the disease would enable doctors to spot cases earlier, when they might be easier to treat. However, the USPSTF reviewed findings on pancreatic cancer screening in people without symptoms and determined that there is no evidence that screening in this group — or treating cases of pancreatic cancer found on screening tests — reduces deaths from the disease. The task force concluded that the benefits of screening do not outweigh the potential harms.

Could a traumatic experience raise the risk of ovarian cancer? Researchers at the Harvard T.H. Chan School of Public Health and Moffitt Cancer Center found that women who remembered experiencing six or more symptoms of post-traumatic stress disorder (PTSD) had double the risk of later developing ovarian cancer, compared with women who had not reported PTSD symptoms. They were also more likely to develop a more aggressive form of the cancer. The researchers looked at data from more than 50,000 women who participated in the Nurses' Health Study II. Early in the study, women were asked to identify their most stressful life experience and any PTSD symptoms they had experienced following that event. Researchers then looked to see which of the women went on to develop ovarian cancer. The study, published Sept. 5 in Cancer Research, found higher cancer risk persisted even if a woman's PTSD symptoms had occurred decades in the past. Past animal research suggests that stress hormones may spur tumor growth.

Q. I have terrible dandruff that just doesn't seem to ever clear up. What can I do to treat it?

A. For most people, using a dandruff shampoo once or twice a week can control this annoying condition, in which the skin on the scalp becomes dry and flakes off. But in some cases, the condition doesn't clear up and actually requires medical attention.

For years, the conventional wisdom about dairy is that we should be eating less of it, and when we do have any it should be low-fat or fat-free. But more recent research suggests that some full-fat dairy in our diets could in fact be beneficial, though the type of dairy still matters.

A widely-advertised facial moisturizer claims to be the best on the market — and sells for $225 per bottle. Should you buy it? Another brand offers a complete skin care regimen — but it comes in 10 different bottles of lotions and potions that all need to be applied daily. Is it worth your time?

Despite manufacturers' claims, many cosmetic products will remove more cash from your wallet than dirt and oils from your skin. You don't need an expensive or lengthy skin care routine — and the good news is, the most effective and reliable regimen is also quick and inexpensive.

Eczema is an itchy rash that's often hard to get rid of. Most people can't help scratching it, which further irritates the skin. Eczema is often, but not always, related to allergies. A common cause is your skin overreacting to everyday irritants, such as dust, soaps and detergents, or even dry, cold air, which triggers an intensely itchy allergic reaction.

Skin affected by eczema becomes dehydrated and dry easily, so treatment involves rehydrating the skin. Baths and showers must be short and not too hot. Afterwards, gently pat your skin dry and promptly apply moisturizers while your skin is still moist. Thick creams that lock in the moisture help the most. Be sure to choose creams or lotions without fragrances or preservatives. Limit the use of soaps and shampoos, too. These products remove the skin's natural oils and worsen dryness. And over-the-counter oral antihistamines can help with the ferocious itch.

Whole grains contain fiber and nutrients that can help your health.

It's a low-carb world, and many people are pushing grains off their plate in an effort to control their waistline. But they may be doing their body a disservice. Whole grains have some unique properties that make them a valuable addition to the diet. Not only do they contain a host of nutrients, such as iron, B vitamins, copper, zinc, and magnesium, but studies have linked diets rich in whole grains to a lower risk of colon cancer, which is a growing health threat for many younger Americans.

"The main benefit of whole cereal grains, such as wheat, oats, and barley, is in the fiber," says Teresa Fung, adjunct professor in the Department of Nutrition at the Harvard T.H. Chan School of Public Health. "Cereal fiber is different from vegetable fiber or bean fiber."

Approximately 1% of the population has vitiligo, a skin condition in which areas of skin lose their color. While topical treatments and light therapy help some, research with a class of medications not previously used for this condition has shown promising results.
