How’s your Hearing—What??

December, 2019

This column is largely about public health issues, i.e. issues that have a general population health impact. Most often those involve the prevention of diseases with direct or indirect effects beyond the individual to at least portions of the rest of the population, as immunizations do.  Last month I wrote about sleep, which has only indirect public health implications resulting from sleepy people driving home from work or elsewhere, or generally not being their best. Mt. Vernon’s John Olson thanked me for the insights it gave him and suggested I might write about hearing loss as a sequel. The only public health issues there are in the possibilities in preventing or diminishing the afflictions; nevertheless, I suspect hearing loss is of interest to many, so here goes!

Deafness is a relatively rare condition until people reach retirement age. Sure, a few youngsters suffer it, but by the time people reach age 70, nearly half of them are significantly deaf by formal testing. Deafness rapidly develops in most of the other half over the next 2 decades; well over 90% over 90 suffer have hearing loss, according to epidemiologic statistics. That number seems a little high to me, but many with the disease hide it well; for instance, they start agreeing with me after the first repeat, even though they have no clue what I just said. So, my impression of how many have significant hearing loss, is undoubtedly an undercount.  

Almost all deafness is due to injury or blockage of both ears. Thank the Lord we are given two ears by evolution, so knocking out one ear is only a minor inconvenience.  Here is how hearing works. Each ear is made up of 3 parts: 

•External ear, the ear lobe and canal

•Middle ear (the ear drum, ear bones, and the air-filled space drained by the Eustachian tubes to the back of the throat

•Inner ear, very complicated, containing:

-Semi-circular canals, like 3 small gyroscopes lined with hair-cell, which, via the 8th cranial nerve, alert the brain where little sand grains inside each canal land, in 3 dimensions, to tell you where you are in relation to gravity

-Cochlea, another long, coiled tube like a snail shell, also lined with hair cells that are twitched by each different frequency in the normal hearing range, low to high, roughly 0.5-2.5 cps [cycles per second, or “Hertz”) 

Deafness is caused predominantly by presbycusis, Greek for “old hearing”, which means the cumulative effects of aging on hearing, almost always from recurrent exposure to loud (at or over 85 decibels) noise, be it music, chain saws, or many other things you can imagine. That level  is a consensus of professionals, although there are no national standards or clinical trials (not surprising, since who would volunteer to be a subject in a study where they might be subjected to high decibel noise daily for many years, to see what happens!) Loud noise repeatedly hitting the middle C hair cell in the cochlea, causes that cell eventually to be damaged. The high-pitched hair cells above high C are the most sensitive to such injury. So, high pitch hearing is usually lost first. And because consonants provide a major part of word meaning, the loss of their whispery, high pitched sounds severely impacts a person’s ability to interpret other’s speech. Vowel sounds are in the 0.5-1.5 cps range and hence are lost much later. Manifesting very similarly is much rarer interference or damage to the auditory nerve from medicines, like the reversible ear-ringing caused by aspirin in moderately high doses (over 1 gm daily), permanently from some medicines, classically antibiotics, like streptomycins, or other diseases like Menniér’s Disease. These types of losses are all categorized as a Sensory-Neural (S-N) hearing loss.

The second most common contributor to presbycusis is ear wax in the external ear. Usually this normal mixture of dead skin, sweat and oil stays soft and leaks out of the canal on its own or with the help of warm water in dry climates like winter. But if it does not, it can build up into very firm, dark -brown plugs. Ineffective efforts to dislodge it with fingers, Q-tips or other tools can pack it even more firmly against the ear drum causing a “conductive” hearing loss. Ironically hearing aids do this very well too. Older people have less oily skin secretions and hence get this condition more easily. Usually it can be prevented by simply running warm water into the ear canals while bathing or showering. And for people with recurrent wax impaction and resultant conductive hearing loss, a family member can gain the skill of looking in there weekly or monthly to prompt more room temperature water irrigation with a bulb syringe and frequent ear drops to soften the impacted wax.

Clinicians can distinguish between S-N and conductive hearing loss by looking in the ear and with simple tuning fork tests called Rinné and Weber. 

So, what can we do to help/cope?

First, prevention: 

•Avoid loud noise damage. Ear protectors work fine, though they can be uncomfortable on a hot summer day. Wear them or ear plugs, which I think are a little less good because they are harder to get a good fit. Make your nearly adult kids to protect their hearing at concerts or using machines; they may thank you decades later.

•Be sure you are not given medicines that can cause permanent damage unless you must have it to survive.

•Run bath water into your ear canals while bathing 

Second, accommodate:

• If wax impaction occurs, regularly check for impacted wax and irrigate the ears clear.

•Speak in low frequencies to presbycusis sufferers. Men’s voices work better than women’s; women can speak in their lowest voices. Don’t shout; that diminishes the clarity of consonants, which are crucial to understanding speech. Look at the person, so they can see your lips move; use confirming gestures. They can begin to learn lip reading that way.

•Hearing loss accompanies dementia often, and each makes the other worse. Isolation can be due to either, and accommodating hearing loss can slow progression of dementia.

•Hearing loss also causes depression; sufferers withdraw from contacts because of frustration with not being able to participate in conversations. Find ways to engage anyway.

•Many users experience “recruitment,” which is a condition where the useful loudness of sound lies in a very narrow decibel range. You may have spoken louder and louder to a deaf person who suddenly says “quieter, you don’t have to shout”; you know then that you overstepped their narrow range. The same can happen with a hearing aids.

•Use assistive devices, just as you would a cane with a bad set of knees. A cheap stethoscope in the sufferers’ ears and held toward you can markedly improve their understanding. Electronic devices are often available at churches, as they are for TV sets and telephones. 

•Explore hearing aids, though beware, there are a lot of shysters out there. Get an evaluation at a hospital audiology center (MaineGeneral centers in Augusta and Waterville, and elsewhere). The problems with hearing aids are that they are moderately hard to keep working, especially with concomitant cognitive problems. They magnify all sounds, not just the ones you want to focus on. Aids can be very expensive, in the many $1000s. 

So, practice prevention starting now, wherever you are on the hearing spectrum. Prevent ear wax build up if you or family members have a problem. Use assistive devices sooner rather than later.

Sleep

Many people experience “problems” sleeping at some point in their lives, more often the older they get and when travelling across several time zones. My wife and I have experienced both recently. I’ll review the issues and some do’s or don’t solutions.

First, aging gradually speeds the internal body clock. When experimenters house teens or adults in a room with a constant level of light 24/7, they tend to develop their own endogenous rhythm, waking and falling asleep at the same times every day after a week or so. Those between 25 and 45 years old tend to exactly match the 24-hour cycles of our earth’s spin around its axis. Teens and younger adults tend to settle into moderately longer, about 25-26 hours., wake/sleep cycles. Older people shorten their days to that of their endogenous (built-in) body clock cycles of less than 24 hours; and the older they are, the shorter those cycles are, down to 21-22 hours a day. So, by the time people reach retirement age, their natural cycle will tend to have them waking up earlier and earlier every day and going to bed earlier and earlier too. Teens are the opposite, going to bed later and waking up in the morning later and later. That’s why the recent big push makes sense, to allow teens to arrive at school later than their middle-aged and older teachers and superintendents tend to schedule classes. Each group’s tendencies are curbed by the sun and scheduled activities.

Travel across time zones can be heartening in one direction, and more stressful going in the opposite direction. So, an old guy, like me, is thrilled to find, when travelling east five time zones to England, he can stay up until after midnight easily, and sleep until 9 am local time instead of awakening at 5 or 6 am for a few days. Teens and young adults traveling west, find that their usual late to bed, late to rise, fits the normal pattern of their elders for the first few days after they arrive. For all, correction for time zone travel is more rapid if one gets some sun or any daytime outdoor exposure around noon local time for a few days.

So usually, the young have trouble falling asleep in the evening, and the older have trouble sleeping late in the morning. The safest and best solutions are to go with the flow. Avoid sedation with medications or alcohol. Antihistamines (like Benadryl, Sominex, Tylenol pm, and many others), can sedate (make you sleepy) somewhat, but are likely to cause confusion the older a person is, because of their effect on the brain. Typical benzodiazepine sleep medicines (Valium, Librium, Ativan and many others), likewise can cause confusion . in spades and are more likely, the older a person is, because their metabolism of such drugs is slower. Alcohol can make people sleepy, but it has an awakening effect several hours later. And the flickering light of a bedtime TV can mess up wake/sleep cycles. Daytime exercise, at least 4 hours before going to bed, can facilitate falling asleep more soundly. 

So, understand your body clock cycles’ tendencies and don’t fight them too hard. Regular bed and awakening times help; avoid shift work, if you possibly can.

Sleep well!  Happy Holidays! And get a flu shot soon; tis the season (see Mt V newsletter, Nov. 2018, p5 about why)!

Influenza This Year in Maine

Dan Onion, MD, MPH

Mt. Vernon/Vienna Health Officer

293-2076; dkonion@gmail.com

December, 2018

Winter is coming and so is influenza. Last year we had a bad year and there was a lot of bad press about immunizations, so let's review this annual epidemic and what we know so far this year.

Influenza is an infectious disease of the upper and lower respiratory tract (nose, throat, breathing tubes and lungs themselves) caused by an influenza virus. Two major types of influenza infect humans, A and B.  "A" types cause most of the disease, injury and death; "B" types are less common and more benign, but are still hard on, and sometimes fatal, to babies and the elderly. Influenza viruses survive over the centuries because they change their coat every few years. Those are, on Type A viruses, surface proteins called hemagglutinin (H) (with subtypes 1-5), and neuramidase (N) (subtypes 1 and 2), against which our bodies make effective antibodies when we are infected or immunized. By changing those coat proteins through genetic natural selection every few years, the slightly different flu virus becomes more infectious because people haven't been previously exposed to that version.

To treat this common disease, boost your family's immunity with a flu shot every year, so none of you catches it or maybe get only a mild case. Years, when most of us have already been infected by and/or immunized against the circulating H/N combination types, cases of illness are fewer and less severe. The US Centers for Disease Control (CDC) makes an educated guess each year about which recent subtypes are going to predominate, and incorporates 3 or 4 of those into vaccine manufactured each fall. The vaccine is egg-based, so the rare person who is truly egg protein allergic (I’ve never met one), can’t take the shot and must use available alternative vaccines.

When the virus changes its coat, as it always does, and/or the US CDC hasn't guessed right, and/or we haven't done a good job of immunizing everybody, then we have worse epidemics. Their severity is usually measured by elementary school absence rates over 20%, higher than average emergency room and office visits for "influenza-like" illnesses, hospitalizations, and deaths.

When given the standard shot into our arm muscle, most of us do fine, suffering at most a mildly sore arm for a day or two. Many claim to have “gotten the flu from the shot,” but this is not possible because there is no live virus in the shot. Most, I think, are describing an aching from the body’s healing up the injection site and getting rid of the dead virus parts, thereby enhancing new antibody formation; that's why the shots work.

The US CDC monitors and regularly reports vaccine "efficacy", calculated as the percentage of people who, after having had a flu shot, later have a worrisome enough illness to prompt a medical visit. But illness visits could also reflect unusually easy access to medical care, and/or other factors. And those numbers are from the same 5 states every year, never Maine. Last year that "efficacy" was only 40%; it usually is around 50%, but occasionally is as high as 60% and rarely as low as 10%. Publicizing only the "efficacy" statistic seems quite misleading. I'd rather they emphasized hospitalization and/or mortality rates, both much "harder" outcomes and calculated for all states. Last year, Maine hospitalization rates for flu were almost 70% higher than in the previous year, confirming a bad season.

Important things to know, understand, and recognize: 

•Influenza is not a viral cold (sore throat, under 100°F temperature degrees, and the patient still able to function). Nor is it gastroenteritis , predominantly nausea, vomiting and diarrhea from gut germs, which we often also call “flu.”

•The vaccine:  This year the vaccine is directed against 3 (trivalent) or 4 (quadrivalent) types: influenza A/H1N1, A/H3N2, B/Colorado and B/Phuket. And we have designer vaccines with the added 4th virus' proteins at quadruple doses, and also with "adjuvants", all to enhance the effect for older or other high risk people. Childhood vaccines for ages 6 months to 8 years old are similarly specific to that age group and usually require two doses. The vaccine can also be given by nasal spray. So far this year, Maine CDC graphs (below) look good with only 34 cases in Maine. But last year at this time, things looked similarly good, so there's no telling for sure. Even if the vaccine match turns out less than ideal, you should get it and not let the perfect be the enemy of the good.

•Three ways people get sick with the flu and to watch out for: 

1. Rapidly super sick patients with overwhelming viral pneumonia: Usually young people, mostly teenagers and young adults. They get sick one night with chills, often have a fever over 101, become prostrate (flat out sick) within hours, always have cough, which may or may not produce sputum; their lungs fill with fluid making them short of breath; they can get confused, turn blue and can die within hours if not hospitalized. If you see these signs, get to an emergency room ASAP, DO NOT DELAY!! Rare, but extremely dangerous.

2. Another group in trouble with delayed complications: especially in toddlers and elderly, who get the usual flu symptoms with fever over 101°, productive cough, feel rotten all over, may have some vomiting (rarely diarrhea), who then develop a secondary bacterial pneumonia. They start to get better after 3-5 days then relapse back with high fever, get sicker again, with more cough, more sputum, if not too weak to produce it, and can die in a few more days if not diagnosed and treated with bacterial antibiotics. Get them to the emergency room as soon as that regression to bad happens.

3. Finally, the rest of those with influenza, have sore throat, fever/chills, cough, feel lousy, often still try to work, then gradually improve over a week and get back to normal within 7-10 days.

•Effective antiviral drugs that help those in groups 2 and 3 above: oseltamivir (Tamiflu) 75 mg and several similar drugs work to ameliorate severity and complications if started within 48 hours of symptoms. Many clinicians will want to test a throat swab before prescribing these but when the flu season gets bad, most will figure hoof beats mean horses and prescribe it even over the phone if your symptoms fit. These drugs also work at lower doses to prevent having flu or at least reduce its complications when a family member has it.

•Think of your friends and neighbors. Don’t work or visit with them when you are sick, if you can help it; not 100% effective because you are spreading the virus a couple days before you get really sick, but worth doing.

Now, late October-early November is the time to get a flu shot. Earlier immunization risks getting the flu while the flu is still peaking in March and April (see 2nd graph below) as the immunization begins to wane 6 months after the getting it. Getting a pneumonia immunization (pneumovax), if you are due, is a good idea too, especially for older adults, because complicating pneumococcal pneumonia (group 2 above) causes many flu deaths.  I had my flu shot 2 weeks ago in mid-October, which should protect me into April. So please get yours!

There is some hope that this annual dance will change soon. After decades of trying, the first universal flu vaccine, a nasal spray, is about to enter its first human trials. It appears to be able to  generate immunity to parts of the virus that are the least variable from strain to strain and thereby protect against all human influenza strains. That would get rid of all this trying to guess which flu strain will be the problem next year.
