Q. I have had a dandruff problem for years. I have tried selenium and zinc shampoos, as well as ketoconazole shampoo. Nothing has worked. Are there other options?

A. Dandruff, which is a chronic skin condition known as seborrheic dermatitis of the scalp, can range from a minor irritant to a severe rash of the entire scalp.

Don't be surprised if your doctor doesn't rush you into treatment.

Urinary tract infections (UTIs) can be tricky in older age. They're not always as easy to spot or treat as in youth. And the decades-long approach to treatment is changing. "We've been hasty in using antibiotics, and we're learning there are significant consequences that can range from side effects of medication to infections with antibiotic-resistant bacteria," says Dr. Helen Chen, a geriatrician at Harvard-affiliated Hebrew Rehabilitation Center.

About UTIs

UTIs can occur anywhere in the urinary tract. The most common places are the bladder (where urine is stored) and the urethra (the tube through which you urinate). Less common, but more serious, is infection of the kidneys, which filter waste and extra water from the blood and make urine. Infections may be triggered by sexual activity, catheters, kidney stones, decreased estrogen in the lining of the vagina, or urine that's pooled in the bladder.

Red meat is associated with an increased risk for developing cardiovascular disease, diabetes, and some types of cancer. Now, a study published online Jan. 9, 2017, by the journal Gut suggests that eating red meat is associated with an increased risk for developing diverticulitis. This occurs when tiny pouches in the wall of the large intestine become inflamed, potentially causing cramps, diarrhea, constipation, and even rectal bleeding. We don't really know what causes diverticulitis, so researchers explored possible dietary links. They analyzed health and diet information reported by more than 46,000 men (ages 40 to 75) over 26 years. Men who ate the most red meat per week (about 13 servings) were 58% more likely to develop diverticulitis during the study period, compared with men who ate the least red meat per week (1.2 servings). The association was strongest for unprocessed red meat like steak. However, the risk for developing diverticulitis was 20% lower when people in the study substituted poultry or fish for a serving of unprocessed red meat each day. The findings don't prove that red meat causes diverticulitis, but other studies have suggested red meat may be a factor in diverticular disease.

Removing a Speck From the Eye

Occasionally, an eyelash or speck of dirt gets into the eye and causes irritation. If tears that form do not wash out the object, it can sometimes be removed by pulling the upper eyelid down over the lower eyelid. The lashes of the lower eyelid may brush out any foreign object that is caught under the upper lid.

If this does not work, try either of the procedures described below.

In preliminary research, sucralose and acesulfame potassium increased insulin levels, although more studies are necessary to determine whether they—or other artificial sweeteners—increase the risk of insulin resistance.

Despite the lack of a universally recognized therapy for nighttime leg cramps, a few approaches may be worth trying.

Few things are more jarring to a night's sleep than shooting calf pains. If you have nocturnal leg cramps, you have lots of company. Although they can strike people at any time of life, they become more common with age. Among people over 60, almost half report having leg cramps, a third say they are awakened by cramps at night, and 15% report weekly episodes.

What causes leg cramps?

The risk of developing stress incontinence or urge incontinence increases along with BMI and body fat percentage. Stress incontinence is also associated with declines in grip strength.

Some experts feel there is evidence that probiotics may help prevent or treat several conditions, such as inflammatory bowel diseases, travelers’ diarrhea, irritable bowel syndrome, and some allergies (particularly eczema).

The realities of treatment can help relieve hearing loss concerns.

Hearing loss is common in older age. It affects one in three people ages 65 or older, and two out of three people ages 75 or older. The condition leaves people struggling to keep up with conversations or simply hear the phone or TV, which can lead to serious problems. "Hearing loss can make a person less likely to engage with friends and family, which can be associated with depression," says Dr. David Jung, an otologist (ear specialist) with Harvard-affiliated Massachusetts Eye and Ear Infirmary.
