It’S A Lousy World

DEAR DR. DONOHUE: My entire family has lice. I am starting a support group for families who have had to experience this awful invasion of their scalps. I have reached the breaking point. Give me a plan for treatment and a timetable for their eradication from our home. — Name Withheld Lest Neighbors Find Out

ANSWER: One of nature’s smallest creatures, the head louse upsets domestic tranquility with more revulsion than most health-endangering illnesses. Head lice bring no disease with them. They are tiny, only 3 millimeters (1/10 inch) in length. They feed on blood and die within a day or two off the scalp. After feeding, lice have a reddish-brown hue. The mother louse glues louse eggs to hair, and those structures are called nits. They are only 1 millimeter (4/100 inch) long. The eggs hatch in six to 10 days. If nits are more than a quarter of an inch from the scalp, the baby louse has already hatched, and the nit is no longer a problem. In an average life span of three months, the mother louse can lay up to 300 eggs.

Lice are not an indication of poor hygiene. Most of the time, they’re introduced into a family by a child who caught them at school. They can infest other family members quickly. Transmission comes from direct contact with an infested individual and, less often, from contact with inanimate objects used by that individual, like hats, combs, brushes and bedding. You’re not alone. Six to 12 million Americans come down with head lice yearly.

Almost all people with head lice have intense scalp itching. A number of methods effectively rid you of the problem. The first medicines used are permethrin (Nix) or pyrethrins (Rid), which are cheap and usually effective, although lice are becoming resistant to them in some locations. A second treatment is given seven to 10 days after the first. Ovide (malathion) is used if lice linger after Nix or Rid. And should Ovide not work, the oral medicine Stromectol (ivermectin) is available. A new medicine is Natroba (spinosad) suspension. It is held in reserve as a last resort. This nightmare should be over in two to three weeks.

DEAR DR. DONOHUE: My husband was told he had prostate cancer in 2010 and had his prostate removed. Now his doctor wants him to have PSA testing. He says he might need radiation because he has prostate cancer. If he has no prostate gland, how can he have prostate cancer? — D.R.

ANSWER: The doctor wants to be sure that cancer cells did not spread from to other body sites. Even though the gland was completely removed, not all the potential sites for cancer spread were removed. That’s all but impossible to do. The PSA test will show if prostate cancer is active in those other places. If it is, then further treatment is required.

The booklet on the prostate gland discusses the PSA test and prostate cancer in detail. Readers can order a copy by writing: Dr. Donohue — No. 1001W, Box 536475, Orlando, FL 32853-6475.
