When sleeplessness starts in the legs

Uncomfortable nighttime leg sensations can spoil your sleep, but you can take steps to relieve it.

Is restless legs syndrome (RLS) the cause of your restless sleep? This exasperating condition triggers abnormal sensations in the legs and an irresistible urge to move them. It can wreak havoc with sleep, leading to daytime fatigue.

Portable ultrasound reveals early signs of heart disease

A portable ultrasound device that detects plaque buildup in arteries may offer a simple, cost-effective way to detect heart disease before it causes any symptoms. A report in the December 2014 Global Heart journal describes findings from a large-scale test of the technology in India, the United States, and Canada.

The innermost layer of an artery's wall (the intima) provides a smooth surface for blood to flow through. The middle layer (the media) contains muscle and elastic fibers that let the vessel expand and contract with each heartbeat. The thicker the intima and the media, the more likely the artery is choked with cholesterol-filled plaque. Using ultrasound, a doctor can easily measure the intima-media thickness in the arteries of the neck and upper leg.

When are opioids safe to take?

Opioids are commonly used to control acute, intense pain. Meditation, yoga, and acupuncture may help control pain when tapering off opioids.

Ask the doctor: Which bone density test should I have?

Q. My doctor has recommended a bone density screening, but the medical center with the full-body scanner is a 45-minute drive from my house. A health fair at a neighborhood church offers a bone density test using a foot scanner. Would that be as accurate?

A. The foot scan is called a quantitative ultrasound, and it usually measures the bone density of the heel bone.
It appears to be at least as good as clinical risk factors—such as older age, family history of bone fractures, low body mass index, smoking, corticosteroid use, and excessive alcohol consumption—for identifying people at high risk for osteoporosis.

"Advanced" cholesterol testing: Is it for you?

A discussion with your doctor can help to determine whether an advanced cholesterol test will be beneficial for you.

For most people, there is no advantage to tests that measure cholesterol and triglyceride particle size.

Healthy travel: Don't let this common hazard spoil your best-laid plans

Long trips come with an increased risk of blood clots deep in the leg veins, which can have serious complications.

Ask the doctor: I'm 75. Do I need a geriatrician?

Q. My doctor, an internist, just retired, and my health plan is asking me to designate a new primary care physician. I'm 75. Would there be advantages to choosing a geriatrician as my new doctor?

A. First, a disclaimer: I am a geriatrician. So my short answer is, "Yes, of course!" But my reasoned, unbiased answer would be, "It depends." If you are a generally healthy 75-year-old woman, a family physician or internist will be able to take excellent care of you. Geriatricians are trained to care for older adults with complex illnesses and are expert in managing the care of people who are frail. Improving your ability to function, and the quality of your life, are the guiding principles of geriatric medicine. We are expert at managing complexity and uncertainty, working with families, and caring for people with serious illnesses who are approaching the end of life. A geriatrician would be a good choice if you have physical or cognitive impairment, if you take a lot of medications, or if your friends and family are involved in your medical care. For people who have several medical problems, we emphasize the role of patient and family preference in making medical decisions, with the patient's goals as our primary focus.
