Ear Piercings Create Open Wounds Susceptible to Bacteria

Dear Doctor: My boyfriend let a friend of his pierce his earlobe and cartilage, and both places got infected. He says things will get better on their own, but I’m worried. What should he be doing?

Dear Reader: When you pierce your ear, whether it’s the soft and fleshy tissues of the lobe, or the thick and dense cartilage that makes up the outer ear, you’re creating an open wound. On top of that, you’re introducing a foreign object into the wound to keep it open until it heals from the inside. Earlobe piercings take from six weeks to two months to heal completely. Cartilage piercings take even longer.

Infection can occur when the site of the piercing isn’t cleaned thoroughly with an antiseptic beforehand. That means bacteria on the surface of the skin can be pushed into the wound, where they can multiply and fester. A needle that hasn’t been completely sterilized can also introduce bacteria into the subsequent wound. Touching an unhealed piercing with dirty hands can introduce bacteria, and failing to keep it clean and dry can lead to infection. So can wearing an earring that’s too tight, which puts stress and pressure on the wound and keeps it from healing properly.

The symptoms of an infected piercing can include warmth, tenderness, swelling, itching, burning and redness at the wound site, and a yellowish discharge that looks like pus. In more serious infections, the swelling can move beyond the immediate area of the piercing and begin to involve the rest of the ear. Because cartilage doesn’t have a lot of blood vessels, infections in that area are harder to treat than those in the earlobe.

Unfortunately, your boyfriend is wrong about infections resolving on their own. If the infection hasn’t progressed very far and is just some minor redness or swelling, he can care for it at home. Start by cleaning both sides of the piercing several times a day using a sterile saline solution. You can make one at home by mixing salt with distilled water. Don’t remove the earring. The wound has to stay open as it heals, otherwise bacteria may become trapped inside the piercing as the hole closes. Hands must be washed thoroughly every time before touching the site or the earring. Other than when rinsing the site, be sure to keep it dry. It’s important to continue this regimen of wound care until the piercing has healed completely.

If things don’t visibly improve in a few days, your boyfriend must seek treatment. If the infection grows or spreads, if there is fever along with the infection, if an abscess develops or if the earring becomes immobile or embedded in the skin, he needs to see a doctor.

Fitful Sleep Not Necessarily a Sign of Alzheimer’s Disease

Dear Doctor: My husband has fallen into a strange sleep pattern. Some nights he’s awake until 3 a.m., tosses and turns all night, then wakes up tired. I’ve read that strange sleep cycles may be linked to Alzheimer’s disease, which his mother had. I’m worried, but what can I do?

Dear Reader: First, a bit of reassurance. More than half of older adults report having problems with sleep, including difficulty falling asleep, too much time spent in light sleep, waking up too often during the night and having trouble staying asleep. These can be the result of illness, anxiety, depression, life changes, a side effect of certain medications, too much electronic screen time or poor sleep habits.

It’s true that disrupted sleep is common among people who have been diagnosed with Alzheimer’s disease. They sleep less during the night, and the quality of that sleep is often poor. As a result, they spend their days feeling drowsy and will often take naps or sleep for hours at a time. Recent research suggests that the onset of fitful or fragmented sleep can also be an early indicator of Alzheimer’s disease, one that precedes the more well-known symptoms of memory problems and cognitive changes.

A study published last year in the journal JAMA Neurology found that people with no obvious cognitive issues, but whose sleep cycles had become altered, were more likely to have clumps of certain types of proteins in their brains. Known as amyloid plaques, these clumps collect between neurons and disrupt the cellular function in the brain.

Another study, published earlier this year in the journal Science Translational Medicine, also assessed sleep patterns in people with no memory or behavioral problems. The researchers found that a drop in the quantity of slow-wave sleep that someone got each night -- that’s the deep sleep that leaves you feeling rested and refreshed -- was associated with a buildup of a brain protein known as tau. Elevated levels of tau brain proteins, which form tangles in the brain and lead to atrophy, are commonly seen in people with Alzheimer’s disease.

Since your husband’s family has a history of Alzheimer’s disease, we suggest that you consider broaching the subject with your family doctor. There is no single test for Alzheimer’s disease at this time, but your doctor has access to a variety of diagnostic tools that can be helpful. This includes taking a detailed medical history, and using specially crafted verbal tests designed to assess cognitive function. If it appears to be necessary, your doctor may suggest a neurological exam that includes brain imaging. Taken together, these will establish a baseline for future comparison.

Cognitive issues aside, getting an adequate amount of high-quality sleep each night is important to many areas of health and well-being. We encourage your husband to discuss his changing sleep patterns with his doctor. It’s possible that they can uncover and address an underlying cause of the change.

Cannabis Use During Pregnancy Linked to Low Birth Weight

Ask the Doctors by by Eve Glazier, M.D. and Elizabeth Ko, M.D

Dear Doctor: Several studies have shown a correlation between marijuana use and low birth weight, and I understand that marijuana today has been cultivated to be much stronger than what was used in earlier years. Should this be a concern for women who are pregnant?

Dear Reader: We’ve written before about the use of marijuana, also referred to as cannabis, during pregnancy, specifically in relation to morning sickness. And while it’s true that cannabis is effective in easing nausea, we recommend against its use during pregnancy.

Cannabis is a complex plant that contains hundreds of chemical compounds, including those with psychoactive effects. Science’s understanding of cannabis’s properties, as well as its long-term effects on the human body, is in its early stages. What we do know is that chemicals in cannabis can pass through a woman’s body and into her fetus, and that may affect development.

Several recent studies have drawn a connection between cannabis use during pregnancy and low birth weight, a term that refers to infants born weighing less than 5 pounds, 8 ounces. Although low birth weight infants can be healthy, they are also at increased risk of complications such as an inability to fight infection, having trouble eating and not gaining weight.

Cannabis use in pregnancy also has been linked to increased risk of preterm birth. A recent study from the Colorado School of Public Health analyzed health data from 3,200 women and found that cannabis use during pregnancy was associated with a 50% higher risk of low birth weight. Close to 90% of women in the survey who had used cannabis during pregnancy also breastfed their babies, adding another unknown to the equation.

As you mention, cannabis products today are 6 to 7 times more potent that they were in the 1970s, according to some estimates. Meanwhile, cannabis use among women who are pregnant has increased more than 60% between 2002 and 2014, according to the National Survey on Drug Use and Health. Current research suggests that 4% to 7% of pregnant women now use cannabis, often in the early months of pregnancy to deal with morning sickness. In a study published earlier this year, which also found a link between cannabis use and low birth weight, 22% of the 2,173 pregnant women screened positive for cannabis use.

Our advice against cannabis use during pregnancy is not based on any specific study. Rather, it’s because too little is known about how the chemical compounds in cannabis may affect a developing fetus or a child’s later development. In our opinion, that lack of knowledge makes the potential risks of cannabis use during pregnancy too great at this time.
