Hair thinning? Get to the root of the problem

Female hair loss is a common problem. Causes of hair loss in women range from pregnancy and hormonal shifts to genetic causes or illness. Some hair loss is also caused by overuse of styling products and tools. Treatment for hair loss depends on the cause, but can include everything from medication to hair transplant surgery.

5 common medications that can have serious side effects

Many medications have the potential for dangerous side effects. For example, angiotensin-converting enzyme (ACE) inhibitors may cause an allergic-type reaction called angioedema; large daily doses of the over-the-counter painkiller acetaminophen can damage the liver and lead to liver failure; and NSAIDs such as ibuprofen and naproxen even when taken as directed can still cause ulcers, stomach bleeding and kidney damage. When taking any medication, be sure to watch for side effects and report new symptoms to the doctor.

What to do about incidental findings

Medical imaging can reveal unexpected anomalies. An incidental finding might be a nodule or tumor (abnormal growths that may be benign or malignant) or a cyst (a fluid-filled or debris-filled sac). For example, the doctor may order a chest x-ray in a person with a bad cough to look for pneumonia, but the radiologist finds nodules instead. Such incidental findings can lead to more testing, more medical bills, and a great deal of anxiety.

Born to move: Human hearts evolved to need exercise

Chimpanzees, which are humans’ closest evolutionary relatives, have hearts with thick, stiff walls. This adaptation reflects their need for short bouts of climbing and fighting. In contrast, prehistoric people had to hunt and gather food to survive, so the human heart evolved to have thinner, more flexible walls. These adaptations reinforce the importance of regular brisk walking or jogging throughout life to stay healthy. Young people who don’t exercise regularly may have hearts that more closely resemble chimpanzee hearts. This may contribute to high blood pressure later in life.

2020 vision: Cardiology trends to watch

Several new cardiology technologies are gaining traction, including digital stethoscopes, handheld ultrasound devices, and a cuffless blood pressure monitor. Designed for use with smartphones or tablets, they hold the promise of faster, non-invasive diagnoses of various heart-related conditions. A lab-on-a-chip may help researchers find better anti-clotting medications, and a drug that lowers stubbornly high cholesterol with just two injections per year is being tested.
